Description

The present invention relates to a mask fitting device, for example, one that is attached to a commercially available sanitary mask or medical mask after it has been put on, or one that is detachably attached to a commercially available sanitary mask or medical mask.

Conventional disposable masks sold in stores have a reinforcing element with a built-in metal wire at the top that fits the shape of the face after the mask is put on, eliminating gaps that mainly occur between the nose and cheeks.
In addition, reusable (mainly washable) masks are cut so that they become roughly spherical when in use and the upper edge does not create a gap that usually occurs between the nose and cheeks. Specifically, the right and left halves are sewn together so that they become roughly spherical when opened.
Conventional breath-leak prevention materials for sanitary masks are attached to the surface of the nose area of the sanitary mask wearer, and the breath-leak prevention plate material is pressed firmly against the surface of the sanitary mask from the outside, eliminating any gaps between the sanitary mask and the area around the nose (see, for example, Figure 5 of Patent Document 1).

However, the technology described in Patent Document 1 uses an adhesive to attach the breath-proof material to the mask, making the mask essentially disposable.

Utility Model Registration No. 3155828

The inventors discovered a new problem with disposable masks, in that the strength of the reinforcing member, especially the center portion, is insufficient.
Furthermore, because reusable masks are designed to be washed, they cannot be reinforced with wires, and the mask's shape means it is prone to slipping when moving the chin, such as when talking, which is a new issue they discovered.
The present invention aims to provide a tighter fit at the top of the mask.

Hereinafter, preferred embodiments of the mask fitting device of the present invention will be described in detail with reference to Figs. 1 to 8 .

Fig. 74 shows a conventional disposable mask 200 in a worn state. The disposable mask 200 is equipped with a reinforcing member 203 incorporating a metal wire. However, even if the reinforcing member 203 is adjusted to fit the face, the mask 200 is pulled from both ends, causing the reinforcing member 203 to be stretched in a straight line. It is believed that the mask 200 is pulled from both ends mainly due to the tension of the rubber straps that attach the mask 200 to the ears. In this way, the reinforcing means 1 of the conventional disposable mask 200 does not have enough strength in the area that comes into contact with the periphery of the nose 300, and the mask 200 cannot be fitted tightly.
The mask fitting device 100 of the present invention solves this problem by reinforcing the fitting action of the reinforcing device 203.
Fig. 105 shows a reusable mask 200 made of cloth. When worn, it takes on a three-dimensional shape close to a sphere in order to effectively cover the face, especially the area around the nose. To achieve this three-dimensional shape, two fan-shaped pieces of cloth are sewn together at the arcs of the fan shape.
As can be seen from the figure before wearing, the two pieces of cloth are fan-shaped, and the part of the hole for hanging over the ear is the center of the arc of the fan (hereinafter referred to as the center of the arc). The distance from the center of the arc to the arc of the fan does not change even when it is rotated around the center of the arc. Therefore, the mask 200 formed in this way has the problem that it is very easy to rotate around the center of the arc. This is the same when the mask 200 is worn. Therefore, there is a problem that the mask 200 easily shifts when opening and closing the mouth during conversation, etc. On the other hand, a mask 200 that does not have a three-dimensional shape (such as the disposable mask 200 described above) is flat when not worn, so when worn, it has a shape like a cylinder whose side is cut in the axial direction along the face. Therefore, shifting the mask 200 up and down means that the distance from the ear to the mask 200 changes. Therefore, it is relatively difficult to shift depending on opening and closing of the mouth, etc.
In addition, the reusable mask 200 is designed to be washable, and therefore, if the reinforcing means 1 is incorporated, there is a risk that the fabric of the mask 200 may be damaged during washing.
Such a problem would not occur if the mask close contact device 100 were provided separately from the mask 200 and made detachable. The mask close contact device 100 of the present invention is detachable, and therefore solves this problem.

(1) Overview of the embodiment The mask 200 is fixed to the mask 200 by pinching the front and back of the mask 200 with magnets 24 or the like, making it easy to put on and take off. In the case of a disposable mask 200, the mask 200 is disposable, but the mask fitting device 100 can be reused. In order to minimize gaps in the mask 200, it is desirable to pinch both sides of the nose 300 with the elastic reinforcing means 1, but in that case, the reinforcing means 1 easily comes off along the slope of the nose side 303. By providing a guide means 6 to be placed on the nose 300 in advance and connecting the guide means 6 and the reinforcing means 1 with a magnetic force or the like, the reinforcing means 1 can be held in an appropriate position and the reinforcing means 1 can be prevented from coming off.

(2) Details of the embodiment FIG. 1 is a perspective view of a mask close contact device 100 to which the present embodiment is applied.
The mask 200 has a thin band-like reinforcement member 203 made of a metal wire wrapped in plastic.
The reinforcing member 203 is arranged parallel to the upper edge of the mask 200, about 1 cm away from the upper part of the mask 200. The mask 200 is a sanitary mask made of nonwoven fabric. The embodiment described below can be applied to both medical masks and cloth masks.
That is,
The mask fitting device 100 has a reinforcing means 1 for fitting at least a part of the upper part of the mask 200 to the face, and
The reinforcing means 1 is fixed to the mask 200 by a fixing means 2, and is detachable. (Corresponding to Appendix 1 ) (See the end of this document for the appendix.)
In order to be called easily removable, it must be possible to reuse it a certain number of times.
For example, the number of times of reuse can be specified in increments of 5 from 3 to 2000.
For example, the mask contact device 100 can be fixed to the mask 200 and can also be detached from the mask 200, but it is not preferable that the detachment be accompanied by destruction of the mask contact device 100 or that the mask contact device 100 be destroyed immediately upon detachment.
That is,
At least a part of the upper part of the mask 200 is a strip-shaped region located a certain distance (including zero) downward from the upper edge of the mask 200 (corresponding to Supplementary Note 2).
The fixed distance is the distance from the top of the mask 200 to both ends of the nostrils 302, and can be in the range of 0 to 5 cm in increments of 1 mm. A distance of 0.5 to 3.5 cm is preferable, a distance of 1 cm to 2.8 cm is more preferable, and a distance of 1 cm to 2 cm is even more preferable. The vertical width of the strip-shaped region can be, for example, 1 mm to 30 mm in increments of 1 mm.
The band-shaped area does not necessarily have to be entirely in contact with the face. In other words, it is sufficient that the band-shaped area is in close contact with the face. The band includes a line.
Regarding the close contact, the mask close contact device 100 may have the effect of reducing breath leakage, reducing the shifting of the mask 200, and preventing glasses from fogging up when the user wears glasses.
For example, the close contact refers to a distance of 0.5 mm or less between the band-like region and the face, which is a distance to which the mask 200 cannot be brought any closer, taking into account the state of the fibers of the mask 200 .

That is,
The fixing means 2 fixes the mask 200 by at least one of sandwiching the front side 201 and the back side 202 of the mask 200 and piercing the mask 200 (corresponding to Appendix 3).
That is,
In the case where the mask 200 has a reinforcing member 203,
Based on the wearing state of the mask 200,
The position where the front side 201 and the back side 202 are sandwiched is such that the reinforcing member 203 itself is sandwiched between the upper and lower sides of the reinforcing member 203 (corresponding to Appendix 4).
That is,
The position where the mask 200 is pierced and fixed is the lower side of the reinforcing member 203 (corresponding to Appendix 4).
As a result, even if the fixing means 2 is pulled upward, the protrusions 211 (described later) come into contact with the reinforcing means 1 , and therefore the protrusions 211 will not come above the reinforcing means 1 .
Furthermore, since the convex portion 211 penetrates the front and back of the mask 200 to hold the fixing means 2, the mask close contact device 100 can be firmly fixed.
If the position where the mask 200 is held is brought to the upper side of the reinforcing member 203 , the position where the front side 201 and the back side 202 are sandwiched will be the upper side of the reinforcing member 203 .
If the position where the mask 200 is held is brought above the reinforcing tool 203, a hole will be created above the reinforcing tool 203. The intrusion of outside air through the hole is stopped by the reinforcing tool 203 of the mask 200, which has the effect of preventing a decrease in the original function of the mask 200 due to the hole being created.
Furthermore, if the mask 200 is reusable, the holes in the mask 200 will be located near the upper end of the mask 200, which has the effect of not spoiling the appearance too much.
That is,
The fixing means 2 can be separated into a front part 21 and a back part 22 (corresponding to Appendix 7).
The front portion 21 is at the front side 201 of the mask 200. The back portion 22 is at the back side 202 of the mask 200.
The front portion 21 and the rear portion 22 are formed in a plate shape and are connected to each other by a linking means 3 (described later).
That is,
The back portion 22 has a protrusion 211, and the protrusion 211 penetrates the front and back of the mask 200, thereby piercing the fixing means 2 into the mask 200 (corresponding to Appendix 8).

The protrusion 211 extends from the back portion 22 in a protruding manner perpendicular to the surface constituting the back portion 22, and the protrusion 211 is a thin cylindrical rod screw. The tip of the rod screw is further pointed and has a configuration similar to a needle, and the tip is approximately spherical with a diameter of 0.5 mm.
The bar thread is a male thread.

The reinforcing member 203 is sandwiched between a front surface 204, which is a surface constituting all or a part of the front surface of the mask 200, and a back surface 205, which is a surface constituting all or a part of the back surface of the mask 200.
The reinforcing member 203 is fixed by adhesive surfaces 206 (including fused surfaces) of a front surface 204 and a back surface 205 that are present at at least one of the top, bottom, left, and right positions of the reinforcing member 203 .
In this embodiment, the mask 200 has a double structure made up of an outer fabric and an inner fabric. The reinforcing member 203 is sandwiched between the outer fabric and the inner fabric at a position about 1 cm from the upper end of the mask 200. In order to fix the reinforcing member 203, the outer fabric and the inner fabric are fused at the top, bottom, left and right positions of the reinforcing member 203, that is, so as to surround the periphery of the reinforcing member 203. This fused surface is called an adhesive surface 206.
Also, the mask 200 may be made of a single piece of fabric. Even in this case, in order to fix the reinforcing tool 203, it is possible to prepare additional fabric that can cover the reinforcing tool 203, sandwich the reinforcing tool 203 between the fabric and the additional fabric, and bond the fabrics together. The part that covers the reinforcing tool 203 and comes on the front side 201 is called the front surface 204, and the part that covers the reinforcing tool 203 and comes on the back side 202 is called the back surface 205. It does not matter whether this is the fabric that constitutes the mask 200 or the additional fabric.
When the additional fabric is on the front side 201, the additional fabric is the front surface 204. And the part of the fabric itself that covers the back side 202 of the reinforcing element 203 is the back surface 205. When the additional fabric is on the back side 202, the additional fabric is the back surface 205, and the part of the fabric itself that covers the front side 201 of the reinforcing element 203 is the front surface 204.
The bonding also includes sewing.
The fused surface is an ellipse measuring 2 mm in the horizontal direction and 1 mm in the vertical direction.

That is,
In the case where the mask 200 has a reinforcing member 203,
The reinforcing member 203 is sandwiched between a front surface 204, which is a surface constituting all or a part of the front surface of the mask 200, and a back surface 205, which is a surface constituting all or a part of the back surface of the mask 200.
The reinforcing member 203 is fixed by adhesive surfaces 206 (including fused surfaces) of a front surface 204 and a back surface 205 that are present at at least one position among the top, bottom, left, and right of the reinforcing member 203,
When the tip of the protrusion 211 is placed against the adhesive surface 206,
The circumference of the tip of the protrusion 211 is equal to or less than the circumference of the outer periphery of the adhesive surface 206 of the mask 200, so that the mask 200 is more easily penetrated from the adhesive surface 206 than from other surfaces. (Corresponding to Appendix 9)
The advantages of this configuration will be explained in detail in the fifth embodiment.
It is apparent that if the tip of the projection 211 is thinner than the length of the fusion surface in the short direction, the hole can be easily drilled.

That is,
The mask fitting device 100 is
A linking means 3 is provided to link the front portion 21 and the back portion 22,
The linking means 3 has a separated state 31 in which the front part 21 and the back part 22 are separated,
The front portion 21 and the back portion 22 can be joined together in a joined state 32.
When the separated state 31 is changed to the combined state 32, the front portion 21 or the back portion 22 is caused to describe a certain trajectory 33 of movement,
When the separated state 31 is changed to the combined state 32, the front portion 21 and the back portion 22 are naturally fixed to the mask 200 (corresponding to Appendix 10).
That is,
In the separated state 31, the opposing surfaces 62 of the front portion 21 and the back portion 22 are in a double-open state.
The combined state 32 is a state in which the open state is closed.
The locus 33 is a circular arc (corresponding to Appendix 11).

The linking means 3 is a hinge provided at the upper ends of the front portion 21 and the back portion 22 .
When viewed from the front, the front portion 21 and the back portion 22 are overlapped in that order in a combined state 32. The front is the opposite side to the face when worn.
The front portion 21 can be rotated about the linking means 3 to open into a double-page spread state. The double-page spread state is a separated state 31. The separated state 31 is shown by a dashed line.
When transitioning from the combined state 32 to the separated state 31, a trajectory 33 is drawn which is an arc.
That is,
When the separated state 31 is changed to the combined state 32, the front portion 21 and the back portion 22 are naturally fixed to the mask 200 (corresponding to Appendix 10).
Since the trajectory 33 is an arc, the position where the front portion 21 and the convex portion 211 intersect changes when transitioning from the combined state 32 to the separated state 31. Therefore, the hole provided in the front portion 21 for the convex portion 211 to penetrate the front portion 21 has an elliptical shape that is long vertically.
When the mask 200 is shifted from the combined state 32 to the separated state 31 , the convex portions 211 perforate the mask 200 , and the front portion 21 and the back portion 22 are naturally fixed to the mask 200 .

That is,
The reinforcing means 1 is deformable and retains its shape once deformed. (Corresponding to Supplementary Note 12)
The reinforcing means 1 is a thin mild steel with a thickness of about 0.5 mm. Mild steel is tough and has some elasticity. Therefore, the reinforcing means 1 can be bent freely to fit the shape of the face and retains that shape. This is called plastic deformation.
Mild steel will return to its deformed shape even if some force is applied to it. This is because the yield point has not been exceeded, and is called elastic deformation.

That is,
The reinforcing means 1 is located along the reinforcing tool 203 at any one of the positions above the reinforcing tool 203, below the reinforcing tool 203, and overlapping the reinforcing tool 203 (corresponding to Appendix 13).
If even a part of the reinforcing means 1 overlaps the reinforcing tool 203, it is determined that the reinforcing means 1 is in a position overlapping the reinforcing tool 203.
In other cases, if the reinforcing means 1 is located above the reinforcing tool 203, it is considered to be on the upper side of the reinforcing tool 203, and if the reinforcing means 1 is located below the reinforcing tool 203, it is considered to be on the lower side of the reinforcing tool 203.
Actual measurements showed that the reinforcing member 203 was embedded at a position between 7 mm and 11 mm from the upper edge of the mask 200 .
The reinforcing member 203 was fixed by a plurality of adhesive surfaces 206 (including fused surfaces) provided in a continuous broken line shape at positions 6 mm and 12 mm from the upper edge parallel to the upper edge.
The adhesive surfaces 206 were also provided on both ends of the reinforcing tool 203 in the longitudinal direction. The adhesive surfaces 206 were provided in the form of dashed lines parallel to the upper edge over a distance of 23 mm from the right and left ends of the mask 200 toward the center. The length of the reinforcing tool 203 was 10.5 cm. One dashed line was provided on the upper side of the reinforcing tool 203 , and two dashed lines were provided on the lower side of the reinforcing tool 203. The second dashed line on the lower side was provided 15 mm from the upper edge.
The size of the mask 200 was 9.5 cm in length and 17 cm in width. The reinforcing member 203 will be described later.
If the reinforcing means 1 is a horizontally long rectangle when viewed from the front, with dimensions of 1 cm length, 8 cm width, and 0.5 mm thickness, it will be as follows. In these cases, the downward direction is considered a positive value.
Being positioned so as to overlap the reinforcing member 203 means that the lower long side of the reinforcing means 1 is positioned in a range of more than 7 mm and not more than 21 mm from the upper side of the mask 200.
Being located above the reinforcing member 203 means that the lower long side of the reinforcing means 1 is located 7 mm or less from the upper side of the mask 200. This may be a negative value (see the second embodiment). In this embodiment, the reinforcing means 1 does not function at 0 mm, so it is greater than 0 mm and is 7 mm or less.
Being located below the reinforcing member 203 means that the lower long side of the reinforcing means 1 is located 21 mm or more from the upper side of the mask 200.

In this embodiment, when the convex portion 211 penetrates the upper side of the reinforcing member 203, the reinforcing means 1 can be disposed on the upper side of the reinforcing member 203 along the reinforcing member 203.
When the convex portion 211 penetrates the underside of the reinforcing member 203 , the reinforcing means 1 can be disposed along the underside of the reinforcing member 203 .
Furthermore, by adjusting the vertical position adjustment means 26 described later, the reinforcing means 1 can be positioned so as to overlap the reinforcing member 203.

For example, if multiple reinforcing means 1 and fixing means 2 are provided, they can be arranged at any position along the reinforcing device 203, such as above the reinforcing device 203, below the reinforcing device 203, or at a position overlapping the reinforcing device 203.

That is,
If a reinforcing tool 203 of the mask 200 is present, the reinforcing means 1 can be located along the reinforcing tool 203 at least one of the positions above the reinforcing tool 203, below the reinforcing tool 203, and a position overlapping the reinforcing tool 203 (corresponding to Supplementary Note 13).
Although this varies depending on the mask 200, actual measurements show that the upper side of the reinforcing device 203 is 7 mm or less from the top end of the mask 200, the position overlapping the reinforcing device 203 is more than 7 mm but less than 11 mm from the top end of the mask 200, and the lower side of the reinforcing device 203 is more than 11 mm away from the top end of the mask 200.

That is,
The reinforcing means 1 is located on at least one of the front side 201 and the back side 202 of the mask 200 (corresponding to Appendix 14).
Providing the reinforcing means 1 on the front surface has the effect of firmly adhering the mask 200. Providing the reinforcing means 1 on the back surface has the effect of improving the appearance since the reinforcing means 1 cannot be seen from the outside of the mask 200.
If two reinforcing means 1 are prepared, the reinforcing means 1 can be positioned on both the front side 201 and the back side 202 of the mask 200. In this way, the mask 200 can be sandwiched by the reinforcing means 1 in addition to the fixing means 2, which has the effect of allowing the mask 200 to be more firmly attached.
When the reinforcing means 1 is located on the back side 202 of the mask 200, it is preferable to cover the reinforcing means 1 with a soft material such as vinyl, which has the effect of making the reinforcing means 1 soft against the skin.
In addition, when the reinforcing means 1 is configured to sandwich both sides of the mask 200, one side can be made of a flexible material such as resin. This makes molding easier and has the effect of improving the design due to the difference in material.
In addition, when the reinforcing means 1 are configured to sandwich both sides of the mask 200, the outer reinforcing means 1 only needs to play a role of pressing from the outside, so flexible, non-stretchable materials such as cloth, vinyl, rope, etc. can be used. The difference in material has the effect of improving the design.

That is,
The mask fitting device 100 is based on the state in which the mask 200 is worn,
The reinforcing means 1 is provided with a vertical position adjustment means 26 for adjusting the vertical position of the reinforcing means 1 relative to the fixing means 2. (Corresponding to Appendix 15)
That is,
The mask fitting device 100 is configured as follows, based on the state in which the mask 200 is worn:
The reinforcing means 1 is provided with a left-right position adjustment means 27 for adjusting the left-right position of the reinforcing means 1 relative to the fixing means 2. (Corresponding to Supplementary Note 16)

One of the vertical position adjustment means 26 and the horizontal position adjustment means 27 is a hole in the shape of a character "King" with a horizontal bar added (hereinafter referred to as "King") provided in the reinforcing means 1. The character "King" consists of four ovals arranged in parallel at equal intervals in the horizontal direction and one oval in the vertical direction.
The other of the vertical position adjustment means 26 and the horizontal position adjustment means 27 is a metal disk, such as a batch back screw, having a female thread at the center. The female thread is screwed into the male thread of the protrusion 211.
A protrusion 211 penetrates the reinforcing means 1 from the back to the front at one of the holes of the character "KING". The protrusion 211 protruding to the front is screwed into a disk. This allows the position of the reinforcing means 1 to be adjusted up, down, left, right, without changing the position where the protrusion 211 penetrates the mask 200. The left-right position can be adjusted by moving the protrusion 211 in the direction of the horizontal bar of the character "KING". The up-down position can be adjusted by changing the level of the horizontal bar at which the protrusion 211 is located.

For example, if the car is currently at the first level of the horizontal bar, the reinforcing means 1 is moved so that the convex portion 211 is at the position of the vertical bar of the character "KING". This is equivalent to moving the convex portion 211 relatively. Then, when the convex portion 211 reaches the position of the vertical bar, the reinforcing means 1 is moved so that the convex portion 211 is at the position of the second level of the horizontal bar. Once the convex portion 211 reaches the second level, the reinforcing means 1 can be moved left and right. This operation is similar to when the shift position of a manual transmission vehicle is H-shaped, and the driver can freely change gears to match the shape of the H. Then, when the reinforcing means 1 is at the appropriate position, the female screw is rotated in the direction of tightening at the center of the thickness direction of the disc to fix the reinforcing means 1 in place.

Next, the operation of the embodiment configured as above will be described.
The user determines the location where he/she wants to fasten the reinforcing means 1 to the mask 200 .
The reinforcing means 1 is applied to the front side 201 of the mask 200 .
The reinforcing means 1 is placed below the reinforcing tool 203. The upper side of the reinforcing means 1 is placed at a position where it comes into contact with the lower side of the reinforcing tool 203. This is because the reinforcing tool 203 is inserted in the mask 200, creating a step on the surface of the mask 200, and the reinforcing means 1 is to be fitted into the lower part of this step.
By doing so, even when the mouth is opened and closed while talking, etc., the reinforcing means 1 is caught on the step, so that the mask fitting device 100 is unlikely to slip, and furthermore, even if the user opens his/her mouth, the upper surface of the mask 200 is unlikely to drop.

The user places the fixing means 2 in a double-open state, i.e., in a separated state 31, with the front part 21 on the top and the back part 22 on the bottom. The fixing means 2 is positioned so that it can pass through the character "KING" of the applied reinforcing tool 203. Since the fixing means 2 has the vertical position adjustment means 26 and the horizontal position adjustment means 27, it is sufficient that the fixing means 2 can pass through any position of the vertical bar in the center of the character "KING".
The mask 200 is pierced at the tip of the protrusion 211 from the adhesive surface 206. The position at which the mask 200 is pierced and fixed is selected to be below the reinforcing member 203. When the mouth is opened while talking, the mask 200 is pulled down by the chin.
Therefore, the mask contact device 100 tends to shift upward relative to the mask 200. The mask contact device 100 is pierced to the lower side of the reinforcing device 203, so that the convex portion 211 does not come above the reinforcing device 203 by hitting the reinforcing device 203 of the mask 200. Therefore, the mask contact device 100 can be prevented from shifting. To obtain this effect, it is preferable to select the adhesive surface 206 closest to the lower side of the reinforcing device 203. The adhesive surface 206 is provided in one or two rows along the upper and lower sides of the reinforcing device 203 in order to fix the reinforcing device 203 to the mask 200. The convex portion 211 is inserted into the hole in the center of a metal disk, and the disk is temporarily fixed by rotating it around the central axis of the disk.

The user adjusts the vertical and horizontal positions of the reinforcing means 1 so that the convex portion 211 is located at any one of the positions of the character king.
The user wears the mask 200.
The reinforcing means 1 is deformed to fit the face. Since the deformation exceeds the yield point of the metal of the reinforcing means 1, the reinforcing means 1 maintains its shape.
In this state, the user rotates the disc about the central axis thereof to fix the position of the reinforcing means 1 relative to the fixing means 2.
If the user thinks that the position of the fixing means 2 is not appropriate, the position can be readjusted by loosening the screw between the disk and the protrusion 211.
It is also possible to use a configuration in which both the reinforcing means and the mask are sandwiched between the front and back portions.
In this way, the reinforcing means 1 is sandwiched between the wide areas of the front and back surfaces, so the hole in the reinforcing means 1 can be a square or other shape that fits (encompasses) the character for "king" instead of a square. It can also be a polygon or circle instead of a square. In this case, there is an effect that it becomes easier to attach the mask fitting device 100 to the mask 200.
Furthermore, if the mask 200 is allowed to be damaged,

That is,
The left-right position adjustment means 27 adjusts the intervals 25 between the fixing means 2 when there are a plurality of fixing means 2. (Corresponding to Supplementary Note 17)
In order to prevent damage to the mask, the fixing means may be configured to connect the front and back parts with magnetic force, or the fixing means may be configured to sandwich the front and back sides with elastic force.
For example, a case where the coupling is performed by magnetic force will be described.
In this embodiment, there was a protrusion on the back side. Instead, the protrusion is placed on the front side. The front and back sides have a magnetic force and attract each other.

The front portion 21 is provided with a bar screw that protrudes perpendicularly from the surface, and the reinforcing means 1 is provided with a hole shaped like a king. The reinforcing means 1 is fixed by screwing the bar screw with a metal disk such as a batch back screw. The vertical and horizontal positions of the reinforcing means 1 can be adjusted by loosening the screw on the disk. Also, in this state, the interval 25 of the fixing means 2 can be widened. In conjunction with these adjustments, the position of the fixing means 2 relative to the mask 200 may be moved. However, since the front portion 21 and the back portion 22 are only attracted by magnetic force, it is easy to move the fixing means 2 relative to the surface direction of the mask 200 even in the attracted state.
Once the adjustment of the gap 25 has been completed, the screws of the disk are tightened to fix the reinforcing means 1 to the fixing means 2.
There are other ways to bond them besides magnetically.
For example, the same operation can be achieved by configuring the front and back of the mask 200 to be sandwiched between the front portion 21 and the back portion 22 by elastic force, and providing the front portion 21 with a rod screw that protrudes perpendicularly from the surface.

Even when the mask 200 is temporarily removed from the face, there is no need to remove the mask fitting device 100 from the mask 200, and the mask fitting device 100 can be stored in a state in which it is fixed to the mask 200. Therefore, there is an effect that the mask 200 can be worn immediately when it is re-attached. The same applies to the following examples.
When removing the mask fitting device 100, the above-mentioned operations are generally reversed.
The screws connecting the disk and the protrusion 211 are loosened, and the disk is removed from the protrusion 211. Then, the reinforcing means 1 is removed from the protrusion 211.
The linking means 3 is set to the separated state 31. The protrusions 211 penetrating the mask 200 are pulled out of the holes, and the fixing means 2 is removed from the mask 200.
When storing, if the mask fitting device 100 is stored in a state where it is attached to the mask 200, loss of each part can be prevented.
For example, the linking means 3 is brought into a coupled state 32, and the protruding portion 211 is protruded from the front portion 21. A character "K" is passed through the protruding portion 211, and a disk is screwed onto the protruding portion 211 protruding from the reinforcing means 1.

As described above, with the mask fitting device of this embodiment, the reinforcing means presses the upper part of the mask, allowing the upper part of the mask to fit more closely.

Next, a second embodiment will be described.
In the first embodiment described above, the fixing means 2 is located at the same position to clamp the front side 201 and the back side 202, whereas in this second embodiment, the fixing means 2 is located at a different position, so that the mask 200 is effectively clamped.
FIG. 3 is a perspective view of the mask contact device in the second embodiment (where the clamping positions of the fixing means 2 are separated).
The same components as those in the first embodiment shown in Fig. 1 are designated by the same reference numerals, and the description thereof will be omitted as appropriate. This also applies to the following embodiments.

Figure 3 shows a perspective view of a mask fitting device 100 to which this embodiment is applied (where the clamping positions of the fixing means 2 are separated).

That is,
The fixing means 2 fixes the mask 200 by sandwiching the front side 201 and the back side 202 of the mask 200 (corresponding to Supplementary Note 3).
That is,
The sandwiching is performed by the force of the elastic body 23 returning to its original shape (corresponding to Appendix 5).
The reinforcing means 1 is a deformable rod of soft iron.
The fixing means 2 in the center is a rod-like metal member. The fixing means 2 is connected to the reinforcing means 1 via a bearing 294. The bearing 294 is disk-shaped, with the reinforcing means 1 passing through the center of the disk. The bearing 294 rotates while keeping the surface constituting the disk perpendicular to the reinforcing means 1. Therefore, the fixing means 2 in the center also rotates around the reinforcing means 1 as an axis. The bearing 294 is fixed with a set screw so that it does not move left or right.
The bearing 294 and the set screw function as the left/right position adjustment means 27 .

That is,
The mask fitting device 100 has a left-right position adjustment means 27 for adjusting the left-right position of the reinforcing means 1 relative to the fixing means 2 (based on the state in which the mask 200 is worn) [corresponding to appendix 16]
The fixing means 2 on both sides also have left and right position adjustment means 27. This will be described later.
The side of the fixing means 2 connected to the reinforcing means 1 is partially hollow and pipe-shaped. A helical spring 293, which is the elastic body 23, is inserted into the hollow part. The elastic body 23 is biased. The helical spring 293 is in contact with the cam 291 via a steel ball 292. The ball 292 is pressed against the cam 291 by the helical spring 293, and moves to the side of the cam 291 where the thickness is thinner. Therefore, in the illustrated state, the fixing means 2 in the center tries to rotate clockwise around the reinforcing means 1. In other words, the fixing means 2 on both sides try to rotate counterclockwise around the reinforcing means 1. Therefore, the fixing means 2 in the center and the fixing means 2 on both sides sandwich the mask 200, and the sandwiching is performed by the force of the elastic body 23 returning to its original shape.

That is,
The mask fitting device 100 pinches the mask by the force of the elastic body 23 returning to its original shape. (Corresponding to Supplementary Note 5)
When the fixing means 2 is rotated counterclockwise, at a certain point, the ball 292 passes over the peak of the cam 291 (the part of the side of the cam 291 that is farthest from the central axis). Then, the fixing means 2 in the center tries to rotate counterclockwise due to the force of the helical spring 293.
Therefore, when the cam 291 is exceeded, the tips of the fixing means 2 in the center and the fixing means 2 on both sides tend to open, which has the effect of facilitating attachment and detachment.
The reinforcing means 1 is a deformable rod of soft iron. Before use, it extends in a straight line. However, when used, it is deformed to fit the face.
Then, the fixing means 2 tries to deform the mask 200,
That is,
It can be said that the sandwiching is performed by the resistance force that causes the mask 200 to return to its original shape after being deformed into the shape of the fixing means 2 (corresponding to Supplementary Note 5).
This means that although the reinforcing member 203 is deformed beyond the yield point, it also has elasticity and therefore tries to return to a certain shape. This force that tries to return to a certain shape is called resistance.

Based on the wearing state of the mask 200,
The position where the front side 201 and the back side 202 are sandwiched straddles the upper and lower sides of the reinforcing member 203, and also sandwiches the reinforcing member 203 itself.
That is,
In the case where the mask 200 has a reinforcing member 203,
Based on the wearing state of the mask 200,
The position where the front side 201 and the back side 202 are sandwiched is at least one of the upper side and the lower side of the reinforcing member 203 (corresponding to Appendix 4).

The reinforcing means 1 is deformable and once deformed, retains its shape.
The reinforcing means 1 is a wire made of mild steel with a diameter of about 1 mm. Mild steel is tough and has some elasticity. Therefore, the reinforcing means 1 can be bent freely to fit the surface of the face and retains that shape. This is called plastic deformation. Plastic deformation is deformation that remains even after the external force is removed, and occurs when an external force exceeding the yield point is applied.
As long as the yield point is not exceeded, the material will return to its original shape even if some force is applied. This is called elastic deformation.
Elastic deformation is a deformation in which an object that has been deformed by an external force returns to its original shape when the external force is removed.

That is,
The reinforcing means 1 is located above the reinforcing tool 203 along the reinforcing tool 203 (corresponding to Appendix 13).
The reinforcing means 1 is located at or above the upper end of the mask 200. Since the mask fitting device 100 has a plurality of fixing means 2, even if it is configured above the mask 200, at least a part of the upper part of the mask 200 can be fitted closely along the face. In the embodiment, the number of fixing means 2 is three, but three or more may be used to better fit the shape of a person's face.
The fixing means 2 arranged on both sides are in the form of a pipe and a rectangular plate joined together. The short side of the rectangle is joined parallel to the axial direction of the pipe. The reinforcing means 1 passes through the inside of the pipe, and the pipe and the reinforcing means 1 are fixed together by a set screw that passes through the pipe from the side in the direction of the central axis. In other words, by loosening the set screw, the reinforcing means 1 can be freely moved left and right relative to the fixing means 2. In other words, the left and right position of the reinforcing means 1 relative to the fixing means 2 can be adjusted.

That is,
The mask fitting device 100 has a left-right position adjustment means 27 for adjusting the left-right position of the reinforcing means 1 relative to the fixing means 2 (based on the state in which the mask 200 is worn) [corresponding to appendix 16]
That is,
When there are a plurality of fixing means 2, the left-right position adjustment means 27 can adjust the intervals 25 between the fixing means 2 (corresponding to Supplementary Note 17).
That is,
The space securing means 5 extends from the fixing means 2 and secures a space 51 for intake air. (Corresponding to Supplementary Note 19)
That is,
The fixing means 2 sandwiches the upper part of the mask 200, thereby securing a space 51 (corresponding to Supplementary Note 20).

The central fixing means 2 on the space securing means 5 side may be made hollow, a rod-shaped member may be inserted therein, and this mechanism may be used to connect the space securing means 5 and the central fixing means 2 to form an expandable structure. This allows the space securing means 5 position adjustment means to be realized.
Here, sandwiching does not only mean sandwiching the front side 201 and the back side 202 at the same position, but may mean pressing the front side 201 at a position different from the position at which the back side 202 is pressed.

Next, the operation of the embodiment configured as above will be described.
The user adjusts the fixing means 2 in the center so that it forms a positive angle with respect to the fixing means 2 on both sides (hereinafter, this will be referred to as a positive state. Note that a state in which the fixing means 2 in the center forms a negative angle with respect to the fixing means 2 on both sides will be referred to as a negative state).
The tip of the central fixing means 2 is open with respect to the fixing means 2 on both sides. The user moves the mask fitting device 100 to a position where the reinforcing means 1 is parallel to the upper end of the mask 200.
The user moves the mask contact device 100 from above to below to a position where the fixing means 2 on both sides and the fixing means 2 in the center can clamp the front side 201 and the back side 202 of the upper part of the mask 200.
The user rotates the central fixing means 2 in a clockwise direction to bring it into a negative state.
Then, the mask 200 is deformed so that the central portion of the mask 200 protrudes from both ends, and the mask fitting device 100 is fixed in place by the resistance of the mask 200 trying to return to its original shape.
Next, a case where the mask close contact device 100 is removed from the mask 200 will be described.
The fixing means 2 in the center is rotated counterclockwise to bring it into the normal state.
By setting the mask 200 in the normal position, the central portion of the mask 200 is recessed further than both ends, so that the fixing means 2 is separated from the mask 200 and the mask contact device 100 can be removed from the mask 200.
In other words, the mask contact device 100 is freely detachable.
By returning the reinforcing means 1 to the normal position and loosening the set screws of the fixing means 2, the left-right position of the reinforcing means 1 relative to the fixing means 2 can be adjusted, and the individual intervals 25 of the fixing means 2 can be adjusted.
That is,
The left-right position adjustment means 27 adjusts the intervals 25 between the fixing means 2 when there are a plurality of fixing means 2 (corresponding to Supplementary Note 16).

This allows adaptation to individual differences.
In addition, the space securing means 5 can be pressed from above the mask 200, set in a positive state to adjust the position of the mask contact device 100, and then set in a negative state to fix it to the mask 200, thereby providing the effect of making it easy to adjust the position.

As described above, with the mask fitting device of this embodiment, the reinforcing means presses the upper part of the mask, allowing the upper part of the mask to fit more closely.

Next, a third embodiment will be described.
In the first embodiment described above, the fixing means 2 is fixed to the mask 200 by piercing it, whereas in this third embodiment, the clamping is performed by magnetic attraction.
FIG. 4 shows a rear view of the mask close contact device 100 in the third embodiment (wherein the fixing means 2 is by magnetic force (rear view)).

That is,
Mask fitting device 100
The fixing means 2 fixes the mask 200 by sandwiching the front side 201 and the back side 202 of the mask 200 .
The position where the front side 201 and the back side 202 are sandwiched is at least one of the lower sides of the reinforcing member 203 (corresponding to Appendix 4).
That is,
The clamping is done by the magnetic attraction force. (Corresponding to Appendix 5)

The fixing means 2 can be separated into a front part 21 and a back part 22 .
The front part 21 is a button-shaped (sometimes called cylindrical or cylindrical) magnet 24. The magnet 24 is very strong, with a magnetic flux density of 280 millitesla. The other examples below also use the same magnet 24. The button-shaped magnet 24 is sometimes called a button magnet 24.
The back portion 22 is a thin iron plate having a substantially square shape with dimensions of 1.5 cm in length, 1.5 cm in width, and 0.5 mm in thickness.
The vertical dimension of the back portion 22 is preferably 0.2 cm to 6 cm. Within this range, the vertical dimension may take any value in increments of 0.1 cm. The horizontal dimension of the back portion 22 is preferably 0.2 cm to 6 cm. Within this range, the horizontal dimension may take any value in increments of 0.1 cm.
The larger the length and width are, the easier it is to ensure the attractive force of the magnet 24. In addition, the effect of sandwiching the mask 200 in cooperation with the reinforcing means 1 can be expected, and the displacement of the mask 200 can be prevented.
Therefore, the vertical dimension is preferably 1 cm or more, more preferably 1.5 cm or more, and even more preferably 2.0 cm or more.
Similarly, the lateral dimension is preferably 1 cm or greater, more preferably 1.5 cm or greater, and even more preferably 2.0 cm or greater.
However, if the length and width are large, the back portion 22 becomes heavy.
Therefore, the vertical dimension is preferably 2 cm or less, more preferably 1.5 cm or less, and even more preferably 1 cm or less.
Similarly, the lateral dimension is preferably 2 cm or less, more preferably 1.5 cm or less, and even more preferably 1 cm or less. The thickness of the back portion 22 is preferably 0.2 mm to 3 mm. The thickness can be freely set in increments of 0.1 mm. The greater the thickness, the stronger the mask 200 can be held. Also, the force of attraction to the magnet 24 will be greater. The thickness is preferably 0.3 mm or more, more preferably 0.4 mm or more, and even more preferably 0.5 mm or more.
On the other hand, if the thickness is too large, it becomes difficult to deform the reinforcing means 1 along the face surface, and the reinforcing means 1 becomes heavy. Therefore, the thickness is preferably 1 mm or less, more preferably 0.7 mm or less, and even more preferably 0.5 mm or less.
Regarding the thickness, in the case where the fixing means 2 is made of a magnetic soft iron plate (including the case where it is a part of the reinforcing means 1), the thickness is the same in the other embodiments.
In this embodiment, it is also possible to bring the reinforcing means 1 to the back side 202 by changing the position of the magnet 24. In that case, the back part 22 described above functions as the front part 21, and the above-mentioned dimensional ranges are the same in that case as well.

The back part 22 is made of soft iron, which is a magnetic material. In this specification, the magnetic material refers to a ferromagnetic material among diamagnetic materials, paramagnetic materials, and ferromagnetic materials. Therefore, the back part 22 is attracted to the front part 21 by the magnetic force of the front part 21.
The reinforcing means 1 is made of a plate of soft iron, which is a magnetic material.
The reinforcing means 1 has a horizontally long rectangular shape when viewed from the front, and has dimensions of 1 cm in length, 8 cm in width, and 0.5 mm in thickness.
The vertical dimension is preferably in the range of 0.1 cm to 5 cm. Within this range, the vertical dimension may take any value in increments of 0.1 cm.
The horizontal dimension is preferably in the range of 3 cm to 20 cm. Within this range, the horizontal dimension may take any value in increments of 0.5 cm.
The larger the length and width, the more closely the mask 200 can be fitted.

From this point of view, the horizontal dimension is preferably 5 cm or more, more preferably 7 cm or more, and even more preferably 8 cm or more. The vertical dimension is preferably 0.5 cm or more, more preferably 1 cm or more, even more preferably 1.5 cm or more, and even more preferably 2 cm or more.
If the dimensions are too large, it will be heavy and look bad.
From this point of view, the lateral dimension is preferably 8 cm or less, more preferably 7 cm or less, and even more preferably 5 cm or less.
The vertical dimension is preferably 2 cm or less, more preferably 1.5 cm or less, even more preferably 1 cm or less, and even more preferably 0.5 cm or less.
The thickness of the reinforcing means 1 is preferably 0.2 mm to 5 mm. The thickness may be any value in increments of 0.1 mm.
The greater the thickness, the stronger the mask 200 can be held, and the stronger the force with which the mask 200 is attracted to the magnet 24.
From this point of view, 0.3 mm or more is preferable, 0.4 mm or more is more preferable, and 0.5 mm or more is even more preferable.
On the other hand, if the thickness is too large, it becomes difficult to deform the reinforcing means 1 along the face surface, and the reinforcing means 1 becomes heavy.
From this point of view, 1 mm or less is preferable, 0.7 mm or less is more preferable, and 0.5 mm or less is even more preferable.
The above dimensions are the same in other embodiments when the reinforcing means 1 is made of a magnetic soft iron plate (including the case where part of the reinforcing means 1 serves as the fixing means 2).

Since the fixing means 2 is made of a magnetic material, the back part 22 is also attracted to the reinforcing means 1. The magnet 24 may be more firmly fixed to the reinforcing means 1 with an adhesive or the like. The reinforcing means 1 itself may be made magnetic to serve as the front part 21. The back part 22 may also be made magnetic. An example in which the back part 22 is made of a magnet 24 is shown in FIG. 12.
In addition, since the magnet 24, which is the back portion 22, is disposed on the back side 202 of the reinforcing means 1, the magnet 24 protrudes from the reinforcing means 1 toward the face. In order to fit this to the surface of the reinforcing means 1, a hole of the same size as the magnet 24 can be drilled in the reinforcing means 1, and the magnet 24 can be fitted into this hole. The periphery of the magnet 24 and the corresponding hole in the reinforcing means 1 are bonded and fixed with an adhesive or the like. In this way, the magnet 24 protrudes from the reinforcing means 1 to the opposite side of the face. This makes it possible to hold the periphery of the nose 300 more strongly. When the magnet 24 is fixed to the reinforcing means 1 by a means other than magnetic force, that is, when the magnet 24 is fixed to the reinforcing means 1 by an adhesive or the like, the reinforcing means 1 does not need to be a magnetic material, and for example, aluminum, brass, plastic, etc. can be used.
FIG. 4 shows a rear view of the mask close contact device 100 in the third embodiment (wherein the fixing means 2 is by magnetic force (rear view)).
The back portion 22 can be bent to fit the shape of an individual's nose 300. In the illustrated state, since the back portion 22 has already been bent to fit the shape of the nose 300, both sides of the reinforcing means 1 are curved to come forward.

That is,
The mask fitting device 100 has a connecting means 3 connecting the front part 21 and the back part 22,
The linking means 3 has a separated state 31 in which the front part 21 and the back part 22 are separated,
The front portion 21 and the back portion 22 can be joined together in a joined state 32.
When the separated state 31 is changed to the combined state 32, the front portion 21 or the back portion 22 is caused to describe a certain trajectory 33 of movement,
When the separated state 31 is changed to the combined state 32, the front portion 21 and the back portion 22 are naturally fixed to the mask 200 (corresponding to Appendix 10).
The linking means 3 is a strip-shaped transparent plastic film. The linking means 3 is adhered to the reinforcing means 1. The linking means 3 is also adhered to the back portion 22.

That is,
In the separated state 31, the opposing surfaces of the front portion 21 and the back portion 22 are in a open state.
The combined state 32 is a state in which the open state is closed.
The locus 33 is a circular arc (corresponding to Appendix 11).
The illustrated state is a double-open state, that is, a separated state 31. The upper end of the mask 200 is located at the vertical half of the linking means 3. In this state, when the linking means 3 is folded back toward the front, a combined state 32 can be achieved in which the front portion 21 and the back portion 22 are combined (see FIG. 5).
When moving from the separated state 31 to the joined state 32, the front portion 21 or the back portion 22 is caused to describe a certain movement trajectory 33, so that the front portion 21 and the back portion 22 are naturally fixed to the mask 200. The joined state 32 is a state in which the open state is changed to a closed state, and the trajectory 33 is an arc.
The reinforcing means 1 is made of soft iron and is therefore deformable.

That is,
The reinforcing means 1 is deformable and retains its shape once it is deformed. (Corresponding to Appendix 12)
That is,
If a reinforcing tool 203 of the mask 200 is present, the reinforcing means 1 is located along the reinforcing tool 203 at at least one of the positions above the reinforcing tool 203, the position below the reinforcing tool 203, and the position overlapping the reinforcing tool 203 (corresponding to Appendix 13).
In this embodiment, it is mainly located below the reinforcing tool 203. It can also be located above the reinforcing tool 203. In that case, it is desirable to adjust the length of the linking means 3. By providing two reinforcing means 1 in two stages, it can also be located both below the reinforcing tool 203 and at a position overlapping the reinforcing tool 203. In that case, the back part 22 becomes a rectangle that is long in the vertical direction.

Furthermore, in order to prevent the fixing means 2 from shifting upward and coming off, a convex portion 211 which is a protrusion protruding perpendicularly to the surface constituting the back portion 22 can be provided, and a hole can be made in the reinforcing means 1 to fit into the protrusion, and the mask 200 can be pierced and secured in place by the protrusion.
Conversely, the convex portion 211 can be provided on the front portion 21 side. In that case, a hole that fits the protrusion is provided in the back portion 22. It is preferable that the hole does not penetrate the back portion 22 so that the convex portion 211 does not protrude from the back portion 22. When this configuration is used, the magnet 24 is brought to the back portion 22 side and a hole is made in the magnet 24. In that case, the surface of the reinforcing means 1 that attracts the magnet 24 becomes the front portion 21. The convex portion 211 is provided from the front portion 21 so as to be approximately perpendicular to the surface of the reinforcing means 1. The convex portion 211 faces the face side. The convex portion 211 can also be provided on both sides of the front portion 21 and the back portion 22.
A hole that fits into the protrusion 211 of the front portion 21 is provided in the back portion 22, and a hole that fits into the protrusion 211 of the back portion 22 is provided in the front portion 21. For example, focusing on the front portion 21, this configuration can be realized by providing the protrusion 211 on the upper side and providing the hole below it. In the example described, the arrangement of the protrusion 211 and the hole is vertical, but they can also be arranged horizontally. Also, the positions of the protrusion 211 and the hole can be reversed.

To adjust the length of the linking means 3, for example, the linking means 3 may be formed on one side of a hook-and-loop fastener, and the other side of the hook-and-loop fastener may be provided on the reinforcing means 1 and the back portion 22, and then connected. When one side of the hook-and-loop fastener is pressed against the other side, the connection is established. When one side of the hook-and-loop fastener is pulled upwards relative to the surface, the connection can be released.
The front part 21 is a magnet 24, and is connected to the reinforcing means 1 by magnetic force.

That is,
The mask fitting device 100 has a vertical position adjusting means 26 for adjusting the vertical position of the reinforcing means 1 relative to the fixing means 2 (corresponding to Appendix 15).
The structure of this embodiment has the advantage of being easy to manufacture.

Figure 12 is an explanation of the cushioning means 28 (back side). If the back part 22 is a magnet 24, the edge of the magnet 24 may come into contact with the wearer and cause pain. In such a case, the periphery of the magnet 24 can be covered with the cushioning means 28 so that the edge does not become a concern. The cushioning means 28 can be made of a material such as silicone rubber. In the illustrated embodiment, the linking means 3 extends from the cushioning means 28. The cushioning means 28 also functions as the breath leakage prevention means 4.

That is,
The mask fitting device 100 is
The mask has a breath leakage prevention means 4 disposed between the back surface of the upper part of the mask 200 and the face, and prevents at least one of the outflow of exhaust air and the inflow of outside air for inhalation from the gap;
The breath leakage prevention means 4 has a back portion 22 (corresponding to Appendix 1 ).

13 is an explanation of the breath leakage prevention means (conceptual side view). Thus, when the reinforcing means 1 is flat, it has a shape as shown in the figure, and when the reinforcing means 1 is curved for use, it conforms to the nose bridge 301 and nose side surface 303.
When the magnet 24 is placed on the reinforcing means 1 side as shown in Figure 4, a member of this shape can fill the gap between the back surface of the reinforcing means 1 and the front portion 21 when the magnet 24 functions as the front portion 21, and can also be used as a member for efficiently holding down the mask 200.

Next, the operation of the embodiment configured as above will be described.
FIG. 4 shows the fixing means 2 using magnetic force (rear view).
First, the back portion 22 is bent in advance so as to fit the nose 300 .
For example, the left and right sides of the back portion 22 are pinched between the fingers, and adjusted so that the front side of the page is convex.
The mask 200 is positioned so that the top end of the mask 200 is located at about the halfway point in the vertical direction of the linking means 3. In this state, the mask 200 is moved in a semicircle around the top end of the mask 200 so that the back part 22 is located downward. Then, the back part 22 and the front part 21 sandwich the front and back of the mask 200 by magnetic force. This is the combined state 32.
The reinforcing member 203 is located above the reinforcing means 1 and the fixing means 2. The thickness of the mask 200 is large in the area where the reinforcing member 203 is located. That is, in the cross section of the mask 200 in the vertical direction, a protrusion is generated at the location of the reinforcing member 203 .
Since the linking means 3 is a flexible sheet, the protrusion of the reinforcing member 203 has the effect of not interfering with the attachment of the mask contact device 100.
For the fixed state of the mask fitting device 100, please refer to FIGS.
9 shows the fixing means 2 being magnetic (when worn). In this state, the reinforcing means 1 is deformed so as to fit closely to the face. Once deformed, the reinforcing means 1 maintains its shape. If necessary, the shape of the back part 22 can be readjusted to fit the shape of the nose 300.

When removing the mask contact device 100 from the mask 200, the above-mentioned operations are carried out in reverse.
The rear portion 22 is attracted to the magnet 24 of the front portion 21. The rear portion 22 can be released from the magnetic restraint and the mask 200 can be pulled downward. If the rear portion 22 is attracted to the front portion 21 again, it is convenient for storage.
As described above, according to the mask fitting device of the present embodiment, the reinforcing means presses the upper part of the mask, so that the upper part of the mask can be fitted more closely.

Next, a fourth embodiment will be described.
In the first embodiment described above, the fixing means 2 is fixed to the mask 200 by piercing it, whereas in this fourth embodiment, the clamping is performed by the magnetic attraction force of two magnets 24.

FIG. 14 shows a fixing means 2 having two magnets 24 (rear view).
In the third embodiment, the front portion 21 has the magnet 24 , but in this embodiment, the back portion 22 has the magnet 24 .
The reinforcing means 1 is made of a magnetic soft iron plate and can be freely deformed in shape.
Therefore, when the linking means 3 is in the combined state 32, the location to which the back portion 22 is attached becomes the front portion 21. The back portion 22 and the reinforcing means 1 are connected by the belt-shaped linking means 3 having a certain length. The location to which the front portion 21 is attached can be freely selected within the range of the width of the reinforcing means 1 in the short direction. If the back portion 22 is attached to a position below the reinforcing means 1, the reinforcing means 1 will be located above the mask 200. Also, if the back portion 22 is attached to a position above the reinforcing means 1, the reinforcing means 1 will be located below the mask 200. In other words, the vertical position of the reinforcing means 1 with respect to the mask 200 can be adjusted depending on the location to which the back portion 22 is attached.

The reinforcing means 1 has a horizontally long rectangular shape when viewed from the front, and has dimensions of 1.5 cm in length, 7.5 cm in width, and 0.5 mm in thickness. The preferable range of dimensions of the reinforcing means 1 is as described in the third embodiment.

That is,
In the mask contact device 100, if a reinforcing member 203 of the mask 200 is present, the reinforcing means 1 is located along the reinforcing member 203 at at least one of the positions above the reinforcing member 203, the position below the reinforcing member 203, and the position overlapping the reinforcing member 203 (corresponding to Supplementary Note 13).
It is considered that the places where the mask 200 is desired to be in close contact vary depending on the shape of the mask 200 and the configuration of the shape of a person's face. This provides the effect of meeting such demands.
Generally, if the reinforcing means 1 is disposed above the reinforcing device 203, breath leakage from the gap between the reinforcing device 203 and the face can be prevented at the rear of the reinforcing device 203. Furthermore, if the reinforcing means 1 is positioned so as to overlap the reinforcing device 203, the effect of enhancing the original function of the reinforcing device 203 can be expected. If the reinforcing means 1 is disposed below the reinforcing device 203, a larger area can be brought into close contact with the face. This is because the area of the reinforcing means 1 is larger than that of the reinforcing device 203. Furthermore, the edge of the reinforcing means 1 fits into the step caused by the thickness of the reinforcing device 203, and there is an effect of preventing the upper part of the mask 200 from shifting even when the mouth is opened or closed.
For an example in which the reinforcing means 1 overlaps the reinforcing member 203, see FIG.
The connecting means 3 is a transparent film, but one side of a hook-and-loop fastener may be used. The other side of the hook-and-loop fastener is attached to the front side of the reinforcing means 1. In this way, the length of the connecting means 3 can be freely adjusted.
In addition, the hook-and-loop fastener can be peeled off while the reinforcing means 1 and the back portion 22 are attached to each other, and the vertical and horizontal positions of the back portion 22 and the interval 25 between the back portions 22 can be adjusted. After the adjustment, the hook-and-loop fastener can be attached.

That is,
The mask fitting device 100 has a vertical position adjustment means 26 for adjusting the vertical position of the reinforcing means 1 relative to the fixing means 2 (based on the state in which the mask 200 is worn) [corresponding to Supplementary Note 15]
That is,
The mask fitting device 100 has a left-right position adjustment means 27 for adjusting the left-right position of the reinforcing means 1 relative to the fixing means 2 (based on the state in which the mask 200 is worn) [corresponding to appendix 16]

That is,
In the mask contact device 100, when there are a plurality of fixing means 2, the left-right position adjustment means 27 adjusts the intervals 25 between the fixing means 2 (corresponding to Supplementary Note 17).

FIG. 18 is an explanatory view (front view) of the breath leakage prevention means, which is a modification of the fourth embodiment.
The mask fitting device 100 is disposed between the back surface of the upper part of the mask 200 and the face, and has a breath leakage prevention means 4 for preventing at least one of the outflow of exhaust air and the inflow of outside air for inhalation through the gap;
The breath leakage prevention means 4 has a back portion 22 (corresponding to Appendix 18).
The connecting means 3 connecting the back part 22 and the reinforcing means 1 is in the form of a band, but it may be configured to become wider as it approaches the reinforcing means 1. The breath leakage prevention means is provided so that the contour of the upper end is shaped like a wave in the figure. The back part 22 is provided at a position slightly below the peak of the wave crest in the figure.
The breath leakage prevention means has a wedge shape in the vertical cross section, with the width narrowing toward the top as shown in the figure. Also, the length of the base of the approximately isosceles triangle that constitutes the wedge shape becomes shorter the further away from the back portion 22. In other words, the average thickness of the breath leakage prevention means in the vertical cross section (hereinafter referred to as the average cross-sectional thickness) is the thickest in the vertical lower part within the range of the width of the back portion 22. The average cross-sectional thickness becomes thinner toward the center and both ends.
This is because breath leakage is noticeable from the corner formed by the face and nose 300, and increasing the thickness of this part in order to fill the gap is effective in preventing breath leakage.

However, in the vicinity of the back portion 22, the thickness is the same as that of the back portion 22.
Moreover, the portion vertically below the range of the width of the back portion 22 (i.e., the range of the diameter of the cylinder) has a thickness substantially equal to that of the back portion 22 .
The thickness decreases in the direction of the lines that define the wave outline.
Then, the edge of the magnet 24 which is the back portion 22 becomes unnoticeable around the periphery of the back portion 22, and functions as a buffer means 28. In addition, the portion connecting the back portion 22 and the reinforcing means 1 functions as a linking means 3.
The material should preferably be flexible and airtight, such as silicone rubber.
If the back portion 22 is a magnet 24, the magnet 24 does not have to be visible on the surface, and may be built into the breath leakage prevention means. The portion where the reinforcing means 1 and the breath leakage prevention means are connected is made thin so that the breath leakage prevention means can be in a separated state 31 or a joined state 32 as the linking means 3 and can rotate around the upper side of the reinforcing means 1 as an axis.

Next, the operation of the embodiment configured as above will be described.
The operation is basically the same as in the third embodiment. The breath leakage prevention means has a two-wave shape as a whole. When wearing it, care should be taken so that the bridge of the nose 301 is in the center between the first and second waves.
FIG. 20 is an explanation (rear view) of the breath leakage prevention means, but the thickness of the breath leakage prevention means is not shown.
The face side of the breath leakage prevention means in the drawing may be a smoothly curved surface that becomes thinner the further away from the magnet 24, with the magnet 24 at the center. The magnet 24 is cylindrical. The face of the magnet 24 opposite the reinforcing means 1 is circular.
A line is drawn on the upper side of the reinforcing means 1 starting from any point on the central axis of the magnet 24. However, the starting point is adjusted so that the line passes through the circumference of the circle. The curved surface defined by this line may be the surface that constitutes the face side of the breath leakage prevention means in the illustration.

In this way, the thickness becomes thinner as it moves away from the magnet 24. It is also possible to make a smooth surface that gradually becomes thinner on the reinforcing means 1 side and the opposite side so as to cover the corner of the cross section passing through the central axis of the magnet 24. It is also possible to increase the thickness slightly and cover the surface that is on the face side of the magnet 24 as shown in the figure.
The breath leak prevention means can also be configured with a cooling agent sealed inside, providing a face cooling function.

As described above, with the mask fitting device of this embodiment, the reinforcing means presses the upper part of the mask, allowing the upper part of the mask to fit more closely.

Next, a fifth embodiment will be described.
In the first embodiment described above, the convex portion 211 of the fixing means 2 is threaded, whereas in this embodiment, the front portion 21 and the back portion 22 are fixed by frictional force.
FIG. 21 shows the fixing means 2 (front view).

That is,
The mask fitting device 100 includes a reinforcing means 1 for fitting at least a part of the upper part of the mask 200 to the face, and
The reinforcing means is fixed to the mask by a fixing means.
It is easily removable. (Corresponding to Appendix 1)
That is,
The fixing means 2 of the mask close contact device 100 is fixed by at least one of sandwiching the front side 201 and the back side 202 of the mask 200 and piercing the mask 200 (corresponding to Supplementary Note 3).
In this embodiment, the mask 200 is fixed mainly by at least one of piercing and fastening, but it can also be said that the mask 200 is fixed by sandwiching the front side 201 and the back side 202 of the mask 200 .

That is,
The fixing means 2 can be separated into a front part 21 and a back part 22 (corresponding to Appendix 7).
That is,
The mask fitting device 100 has a back part 22 having a protruding part 211, and the protruding part 211 penetrates the front and back of the mask 200, thereby piercing the fixing means 2 into the mask 200 (corresponding to Appendix 8).
It is also easy to provide the protrusion 211 on the front part 21. In that case, the length of the protrusion 211 is shortened so that it does not touch the face. Also, the tip of the protrusion 211 may be made gourd-shaped so that it can be stopped in the hollow of the gourd.
It may also be made like a spring hook (see FIG. 108).
The back portion 22 is disk-shaped, and the protrusion 211 is rod-shaped and connected perpendicularly to the surface of the disk. The back portion 22 is made of brass. The diameter of the protrusion 211 is approximately 0.5 mm.
The back part 22 is disk-shaped with a hole in the center that fits with the protrusion 211. As shown in the figure, the reinforcing means 1 is connected to the bottom of the disk. The reinforcing means 1 connects the front parts 21 with a constant gap 25 between them. The gap 25 is 5.5 cm. The reinforcing means 1 is a brass wire with a diameter of approximately 1.2 mm.

That is,
The reinforcing means 1 is deformable and retains its shape once deformed. (Corresponding to Supplementary Note 12)
When a plastically deforming wire is used as part of the reinforcing means 1, its diameter can be any value between 0.2 mm and 50 mm in 0.1 mm increments. This is the diameter of the plastically deforming wire itself, not the diameter of the reinforcing means 1 when it is wrapped with other materials. In such a configuration, it refers to the diameter of the plastically deforming material inside the reinforcing means 1. 0.5 mm to 2 mm is preferable, 0.7 mm to 1.5 mm is more preferable, and 0.9 mm to 1.3 mm is even more preferable.

FIG. 24 shows the fixing means 2 (enlarged side view).
The drawings will be described based on the up, down, left and right directions in the illustrated state.
In the illustrated state, spiral-shaped members (hereinafter referred to as spiral members) extend from the upper and lower sides of the fixing means 2. The spiral members extend to point to the right at first, but change direction midway and are configured to return to the fixing means 2. The upper spiral member spirals in a clockwise direction, and the lower spiral member spirals in a counterclockwise direction. Therefore, there are portions where the upper and lower spiral members face each other. The spiral members are elastic, and the facing portions are biased to press against each other. This portion fixes the convex portion 211 by frictional force. To increase the frictional force, the convex portion 211 may be provided with jagged edges, i.e., small projections and recesses. In the illustrated state, the back portion 22 and the front portion 21 are partially joined. The convex portion 211 is inserted into the mask 200, the front portion 21 and the back portion 22 are joined as shown in the figure, and the convex portion 211 is moved to the right and inserted, so that the front and back of the mask 200 can be completely sandwiched between the front portion 21 and the back portion 22.

FIG. 27 shows what is prevented by the fixing means 2 (the connection between the front portion 21 and the reinforcing means 1).
In this way, the reinforcing means 1 penetrates near the center of the spiral formed by the spiral member. The spiral member is a plate-like elastic body, and the reinforcing means 1 penetrates perpendicularly to the surface that constitutes the spiral. The reinforcing means 1 is soldered to the inside of the spiral. It may also be joined by other methods such as brazing or welding.

FIG. 28 is an illustration of the adhesive surface 206 (rear side).
The entire reinforcing member 203 is covered with a back surface 205, and an adhesive surface 206 is provided around the reinforcing member 203 on the back surface 205. The adhesive surface 206 is one of the line segments that make up the dashed line that appears around the reinforcing member 203. There are many adhesive surfaces 206, so reference numbers are omitted for those that are not representative. The adhesive surface 206 is a rectangle that is 0.5 mm long and 1 mm wide. The dimensions of the adhesive surface 206 vary depending on the mask 200.

That is,
In the case where the mask 200 has the reinforcing member 203, the mask fitting device 100 is
The reinforcing member 203 is sandwiched between a front surface 204, which is a surface constituting all or a part of the front surface of the mask 200, and a back surface 205, which is a surface constituting all or a part of the back surface of the mask 200.
The reinforcing member 203 is fixed by adhesive surfaces 206 (including fused surfaces) of a front surface 204 and a back surface 205 that are present at at least one position among the top, bottom, left, and right of the reinforcing member 203,
When the tip of the protrusion 211 is placed against the adhesive surface 206,
The circumference of the tip of the protrusion 211 is equal to or less than the circumference of the outer periphery of the adhesive surface 206 of the mask 200, so that the mask 200 is more easily penetrated from the adhesive surface 206 than from other surfaces. (Corresponding to Appendix 9)

Note that the tip does not refer only to the tip itself, but to the part up to a certain distance from the tip.
The certain distance is defined as the distance at which the adhesive portion begins to break and at least a hole is created when the mask 200 is pressed against the tip of the adhesive portion while the rest of the adhesive portion is fixed. Also, the certain distance is defined as the distance at which it is possible to confirm that a part of the protrusion 211 has pierced the adhesive portion and protrudes from the inserted side to the other side.
If there is a visible hole protruding and cutting, it is easy to widen it.
For example, the distance can be from 0.1 mm to 1.0 mm in increments of 0.1 mm.
In other words, it is assumed that the adhesive surface 206 is a hole that has been hollowed out in advance from the mask 200 and opened in the mask 200. If the hole is allowed to deform, the protrusion 211 fits into the hole, the shape of the hole is deformed, and the hole can be easily penetrated.
The peripheral length of the tip is the length of the curve that constitutes the outer periphery of the cross section of the convex portion 211 perpendicular to the longitudinal direction.

In this embodiment, the diameter of the cylinder is 0.5 mm. The circumference of the tip is 0.5 mm x pi (=approximately 1.5 mm). On the other hand, the circumference of the outer periphery of the adhesive surface 206 is (0.5 mm + 1 mm) x 2 = 3 mm, which is greater than the circumference of the tip. In addition, the narrowest part of the adhesive surface 206, 0.5 mm in the vertical direction, is equal to the diameter of the cylinder. With this configuration, it can be easily understood that the circumference of the tip of the convex portion 211 is less than the circumference of the outer periphery of the adhesive surface 206 of the mask 200, and therefore the mask 200 is more easily penetrated from the adhesive surface 206 than from other surfaces.
In this embodiment, the perimeter of the outer periphery of the adhesive surface 206 is 3 mm. Since there are differences depending on the product, the periphery can take a value between 1 mm and 20 mm in increments of 0.5 mm.

Next, the operation of the embodiment configured as above will be described.
FIG. 22 shows a blocking type.
The reinforcing means 1 is bent to some extent so as to fit the face. The reinforcing means 1, and in turn the front portion 21 connected thereto, are positioned appropriately with respect to the mask 200.
At that time, it is advisable to align the hole in the front part 21 with one of the adhesive surfaces 206. This adhesive surface 206 is called the selected adhesive surface 206. The convex part 211 is placed against the selected adhesive surface 206 from the back side 202, and a hole is drilled and penetrated. The convex part 211 is fitted into the hole in the front part 21, and pushed in the direction of the back part 22. This allows the front and back of the mask 200 to be sandwiched between the front part 21 and the back part 22, and pierced and fixed by the convex part 211. By performing this for both fixing means 2, the mask fitting device 100 can be fixed to the mask 200. The mask 200 is then put on. If necessary, the reinforcing means 1 is deformed to fine-tune so that at least a part of the upper part of the mask 200 fits closely along the face. In the figure,

That is,
The mask fitting device 100 is fitted to the mask 200 at the upper side of the reinforcing member 203, but it can also be fitted to the lower side (corresponding to Supplementary Note 4).
Depending on the position of the fixing means 2,
That is,
If a reinforcing member 203 of the mask 200 is present, the reinforcing means 1 of the mask fitting device 100 can be located along the reinforcing member 203, above the reinforcing member 203, or below the reinforcing member 203 (corresponding to Supplementary Note 13).

When removing the mask close contact device 100 from the mask 200, the above-mentioned operations can be carried out in reverse. In a simple manner, the protrusions 211 penetrating the front part 21 and the adhesive surface 206 can be pulled out from them.
When storing, if the protrusion 211 is fitted into the hole in the front part 21, the back part 22 can be prevented from being lost.

29 shows a fixing means 2 that is held in place by the linking means 3. That is, this is an example in which the linking means 3 is provided.

That is,
The mask fitting device 100 has a connecting means 3 connecting the front part 21 and the back part 22,
The linking means 3 has a separated state 31 in which the front part 21 and the back part 22 are separated,
The front portion 21 and the back portion 22 can be joined together in a joined state 32.
When the separated state 31 is changed to the combined state 32, the front portion 21 or the back portion 22 is caused to describe a certain trajectory 33 of movement,
When the separated state 31 is changed to the combined state 32, the front portion 21 and the back portion 22 are naturally fixed to the mask 200 (corresponding to Appendix 10).
That is,
In the separated state 31, the opposing surfaces of the front portion 21 and the back portion 22 are in a open state.
The combined state 32 is a state in which the open state is closed.
The locus 33 is a circular arc (corresponding to Appendix 11).
If configured like this,

That is,
In the case where the mask 200 has the reinforcing member 203, the mask fitting device 100 is
Based on the wearing state of the mask 200, it is below the reinforcing member 203 (corresponding to Supplementary Note 4).
That is,
The mask fitting device 100 is
If a reinforcing member 203 of the mask 200 is present, the reinforcing means 1 is located along the reinforcing member 203 or above the reinforcing member 203 (corresponding to Appendix 13).

It is more convenient to say:
FIG. 99 shows an example of the left/right position adjustment means 27.
In the above embodiment, the front portion 21 and the reinforcing means 1 are fixed by soldering, but the above embodiment can easily be provided with a left/right position adjustment means 27.
One side of the left-right position adjustment means 27 is a biased plate-like elastic body shaped like an upside-down L-shape (hereinafter referred to as a L-shaped member).
The other of the left-right position adjustment means 27 is one side of the scroll member. The reinforcing means 1 is sandwiched between the inner surface of the scroll member and both ends of the L-shaped member, and is fixed by frictional force.

That is,
A mask fitting device (100) having a left-right position adjustment means (27) for adjusting the left-right position of the reinforcing means (1) relative to the fixing means (2) (based on the state in which the mask (200) is worn) (corresponding to appendix 16).
The mask fitting device 100 is characterized in that, when there are a plurality of fixing means 2, the left- right position adjustment means 27 adjusts the intervals 25 between the fixing means 2.
As described above, according to the mask fitting device of the present embodiment, the reinforcing means presses the upper part of the mask, so that the upper part of the mask can be fitted more closely.

Next, a sixth embodiment will be described.
In the first embodiment described above, the fixing means 2 is fixed by a screw, but in this embodiment, it is clamped by an elastic body 23.
FIG. 30 shows the fixing means 2 made of an elastic body 23 (front view).
The fixing means 2 is shaped like a double clip. The fixing means 2 is made of brass. The fixing means 2 has an upper surface, a lower surface, and a bottom surface, and these surfaces form an isosceles triangular prism. The base of the isosceles triangle in the cross section of the isosceles triangular prism corresponds to the cross section of the bottom surface. The equilateral sides correspond to the cross sections of the upper surface and the bottom surface. The ends of the upper surface and the bottom surface opposite the base can be opened and closed (see Figures 32 and 33). Hereinafter, the end of the upper surface opposite the bottom surface will be simply referred to as the end of the upper surface, and the end of the bottom surface opposite the bottom surface will be simply referred to as the end of the bottom surface.

Description will be given with reference to Figure 32.
The bottom surface is made of an elastic body 23, and is biased in a direction that reduces the base angle. Therefore, the front and back of the mask 200 can be sandwiched between the edges of the upper surface and the lower surface. An opening and closing assistant member is provided to facilitate opening and closing the edge. The opening and closing assistant member extends from the apex of the isosceles triangle in the direction of the angle that constitutes the base angle, and is twice as long as the equal sides of the isosceles triangle. The end opposite the apex becomes the force point of the lever. This is called the operating part. The apex of the isosceles triangle becomes the point of action, and the angle that constitutes the base angle becomes the fulcrum. Like a double clip, the opening and closing assistant member can rotate around the side that constitutes the apex as an axis.
The fixing means 2 is brazed to the reinforcing means 1. The reinforcing means 1 is a brass wire having a diameter of about 1.2 mm.
The distance 25 between the fixing means 2 is 6 cm, and the length of the mask fitting device 100 in the lateral direction as shown in the figure is 8 cm when the reinforcing means 1 is stretched in a straight line.

That is,
The reinforcing means 1 is deformable and retains its shape once deformed. (Corresponding to Supplementary Note 12)
That is,
The fixing means 2 fixes the mask 200 by sandwiching the front side 201 and the back side 202 of the mask 200 (corresponding to Supplementary Note 3).
Furthermore, if a needle-like protrusion is provided at the end of the lower surface and a hole through which the protrusion passes is provided near the end of the upper surface, the fixing means 2 will fix the mask 200 by both clamping the front side 201 and the back side 202 of the mask 200 and by piercing it into the mask 200.

That is,
In the case where the mask 200 has the reinforcing member 203, the mask fitting device 100 is
Based on the wearing state of the mask 200,
The position where the front side 201 and the back side 202 are sandwiched is either the upper side or the lower side of the reinforcing member 203 (corresponding to Appendix 4).
That is,
The sandwiching is performed by the force of the elastic body 23 returning to its original shape (corresponding to Appendix 5).
That is,
The elastic body 23 is biased (corresponding to Appendix 6).
That is,
If a reinforcing member 203 of the mask 200 is present, the reinforcing means 1 of the mask contact device 100 is located along the reinforcing member 203 at one of the positions above the reinforcing member 203 and below the reinforcing member 203 (corresponding to appendix 13).

Next, the operation of the embodiment configured as above will be described.
FIG. 30 shows the fixing means 2 made of an elastic body 23 (front view).
The reinforcing means 1 is bent to a certain extent so as to fit the face. The operating portion is pinched between fingers and operated to open the ends of the upper and lower surfaces. In this state, the fixing means 2 is sandwiched into the mask 200. By sandwiching the fixing means 2 on both sides into the mask 200, the mask close contact device 100 is fixed to the mask 200. Depending on the user's choice, the position for sandwiching the front side 201 and the back side 202 can be selected to be either the upper side or the lower side of the reinforcing device 203. If the sandwiching position is the upper side of the reinforcing device 203, the reinforcing means 1 is located on the upper side of the reinforcing device 203 along the reinforcing device 203.

Also, if the position of the clamping is the lower side of the reinforcing tool 203, the reinforcing means 1 is located below the reinforcing tool 203 along the reinforcing tool 203. The user wears the mask 200 to which the mask fitting device 100 is fixed, and as necessary, changes the shape of the reinforcing means 1 so as to fit closely along the face. Since the opening and closing assisting member blocks the field of vision, it may be necessary to move it. In that case, the opening and closing assisting member is rotated around the side that constitutes the apex angle of the isosceles triangle as an axis, and faces downward when worn. This has the effect of allowing the opening and closing assisting member to be brought to a position where it does not get in the way when not being worn. Also, if it is biased downward, the mask 200 can be held down, and it has the effect of being used as a part of the fixing means 2.
32 and 33 are explanatory diagrams of the seventh embodiment, but since the fixing means 2 is the same as that of the sixth embodiment, the operation is also the same in the sixth embodiment.

As described above, with the mask fitting device of this embodiment, the reinforcing means presses the upper part of the mask, allowing the upper part of the mask to fit more closely.

Next, a seventh embodiment will be described.
The seventh embodiment is obtained by providing a left/right position adjustment means 27 to the sixth embodiment.

That is,
The reinforcing means 1 is provided with a left-right position adjustment means 27 for adjusting the left-right position of the reinforcing means 1 relative to the fixing means 2 (based on the state in which the mask 200 is worn) (corresponding to Appendix 16).
However, since it is similar to what has been explained so far, the explanation will be omitted.

As described above, according to the mask fitting device of the present embodiment, the reinforcing means presses the upper part of the mask, so that the upper part of the mask can be fitted more closely.
Next, an eighth embodiment will be described.
In the first embodiment described above, the fixing means 2 is fastened by a screw, whereas in the eighth embodiment, the fixing means 2 is fastened by a frictional force, and the reinforcing means 1 is located on the back side 202 .
FIG. 34 shows the reinforcing means 1 on the back side 202 of the mask 200 (front view).
Referring to FIG. 24, the fixing means 2 is the same as that in the fifth embodiment.
The reinforcing means 1 is a brass wire having a diameter of about 1.2 mm. The reinforcing means 1 is soldered to the back portion 22 at portions close to both ends.

That is,
The reinforcing means 1 is deformable and retains its shape once deformed. (Corresponding to Supplementary Note 12)
That is,
The fixing means 2 of the mask close contact device 100 is fixed by at least one of sandwiching the front side 201 and the back side 202 of the mask 200 and piercing the mask 200 (corresponding to Supplementary Note 3).
That is,
In the case where the mask 200 has the reinforcing member 203, the mask fitting device 100 is
Based on the wearing state of the mask 200,
The position where the reinforcing member 203 is pierced into the mask 200 is at least one of the upper side and the lower side of the reinforcing member 203 (corresponding to Supplementary Note 4).
That is,
The reinforcing means 1 is located on the back side 202 of the mask 200 (corresponding to Appendix 14).
Such a configuration makes it very unnoticeable.

Next, the operation of the embodiment configured as above will be described.
The reinforcing means 1 is bent to some extent so as to fit the face.
An appropriate adhesive surface 206 is selected, and the convex portion 211 is pierced from the back side 202. The fixing means 2 on both sides are pierced, and the front portion 21 is fitted from the front side 201. This fixes the mask fitting device 100 to the mask 200. The mask 200 to which the mask fitting device 100 is fixed is worn. If necessary, the reinforcing means 1 is deformed to fine-tune so that at least a part of the upper part of the mask 200 fits closely along the face.
34, when the reinforcing means 1 is finely adjusted, the reinforcing means 1 may protrude from the upper side of the mask 200 in the figure. However, this is not a problem because as long as the position of the fixing means 2 can be fixed relative to the face, at least a part of the upper part of the mask 200 can be made to fit closely along the face. This configuration has the effect of making it very easy to wear.

Figure 107 shows a modified version of the reinforcing means 1 (front view). Like the breath leakage prevention means described above, the thickness is adjusted and it is formed three-dimensionally to cover the depression formed by the corner between the nose side 303 and the face. The material is sponge or silicone rubber, etc., and the reinforcing means 1 is deformable, and has, for example, brass wire inside so that it retains its shape once it is deformed.

By adopting such a shape, even if the pressing force from the front side 201 is insufficient, the mask 200 is placed between the back surface of the upper part and the face, preventing at least one of the escape of exhaust air and the inflow of outside air for inhalation through the gap, and has the same effect as having at least a part of the upper part of the mask 200 closely adhere to the face.

In the drawing, a pin-shaped protrusion 211 is provided from the position of the back portion 22 and approximately perpendicular to the surface formed by the back portion 22. The protrusion 211 is on the opposite side to the face.
It is inserted from the back side 202, and fixed from the front side 201 with the front part 21 as shown in Fig. 24. It is also possible to fix it with magnetic force as in the previous examples. This configuration has the effect of firmly preventing breath leakage and being very inconspicuous.
In addition, the guide means 6 described below can also be formed in this manner. In that case, it is preferable that the back portion 22 is a magnet 24.

As described above, with the mask fitting device of this embodiment, the reinforcing means indirectly presses the upper part of the mask, allowing the upper part of the mask to fit more closely.

Next, a ninth embodiment will be described.
In the eighth embodiment described above, the reinforcing means 1 was straight before use, whereas in the ninth embodiment, the reinforcing means 1 is formed so as to bypass the nose 300 on the surface that constitutes the face.
FIG. 35 shows a reinforcing means 1 on the rear surface (modified front surface).
According to this operating principle, the reinforcing means 1 does not necessarily have to be deformable.
When the mask 200 is worn, the mask 200 is pulled left and right by the ear hooks. This is necessary to keep the mask 200 on the face. This force can be transmitted by avoiding only the portion of the mask 200 that covers the nose 300. In other words, the reinforcing means 1 may transmit the force required to wear the mask 200 by avoiding the portion of the mask 200 that covers the nose 300. In other words, it can be explained that the reinforcing means 1 bears the force transmitted in the longitudinal direction of the mask 200 to keep the mask 200 worn, only in the portion of the mask 200 that covers the nose 300.
To explain in more detail, the tension of the mask 200 is generated by the force of the elastic body of the ear hook trying to return to its original position. For example, the tension is generated by the left ear hook, and this force is transmitted mainly along the upper and lower sides of the mask 200, reaching the right ear hook. At this time, the force transmitted along the upper side of the mask 200 is received by the fixing means 2 on the left side and transmitted to the reinforcing means 1. The reinforcing means 1 transfers this force to the right fixing means 2, bypassing the part of the mask 200 that covers the nose 300 of the mask 200. From the right fixing means 2 onwards, the upper side of the mask 200 transfers this force, and it reaches the right ear hook. The same applies to the force generated by the right ear hook.
Therefore, the portion of the mask 200 that covers the nose 300 can be in a state where no tension is applied. By skillfully adjusting the shape of the reinforcing means 1, the portion of the mask 200 that covers the nose 300 can be made to fit snugly around the nose 300. Since the tension of the mask 200 is transmitted to both the left and right fixing means 2, the portion of the mask 200 that covers the nose 300 can be pressed against the nose 300 using the tension of the mask 200.
In order to realize this, it is sufficient to form the reinforcing means 1 using a wire like the Λ-shaped member of the twelfth embodiment described later. The reinforcing means 1 needs to withstand tension, and it is desirable that it does not easily deform.
As an example that does not use plastic deformation of the wire (i.e., an example in which the reinforcing means 1 is deformable but does not retain its shape once deformed), a means may be provided for adjusting the apex angle of the Λ of the reinforcing means 1 formed in a Λ shape with a screw.
Similarly, the tension of the mask 200 may be borne by something like a case that covers the entire nose 300. If it is configured as a case, a member such as a sponge may be provided inside the case, and the portion of the mask 200 that covers the nose 300 may be pressed against the nose 300 by the elasticity of the sponge.

In order to perform the above operation, the reinforcing means 1 is formed in advance in an inverted U shape (Λ shape) so as to go around the nose 300. The reinforcing means 1 is deformable so that the portion where the mask 200 covers the nose 300 fits snugly around the nose 300.
Others are the same as those in the ninth embodiment. With this configuration, the portion of the reinforcing means 1 present inside the mask 200 is small, which has the effect of reducing irritation to the skin.
If a member that fits the nose 300 as shown in FIG.

That is,
The mask fitting device 100 has a surface, and the surface is arranged at least on the nose side surface 303, and can prevent at least one of the outflow of exhaust air and the inflow of outside air due to inhalation from between the upper part of the mask 200 and the face. (Similar content to Appendix 26)

As described above, with the mask fitting device of this embodiment, the reinforcing means indirectly presses the upper part of the mask, allowing the upper part of the mask to fit more closely.

Next, a tenth embodiment will be described.
In the first to ninth embodiments described above, the reinforcing means 1 is deformable and retains its shape once deformed, whereas in the tenth embodiment, the reinforcing means 1 is configured to clamp the nose side surface 303 by its elasticity.
FIG. 36 shows the reinforcing means 1 sandwiching the nose side surface 303 (rear surface).

That is,
The mask fitting device 100 is fixed by the fixing means 2 by sandwiching the front side 201 and the back side 202 of the mask 200 (corresponding to Supplementary Note 3).
That is,
In the case where the mask 200 has the reinforcing member 203, the mask fitting device 100 is
Based on the wearing state of the mask 200,
The position where the front side 201 and the back side 202 are sandwiched is at least one of the upper side and the lower side of the reinforcing member 203, or the position where the reinforcing member 203 is pierced into the mask 200 is at least one of the upper side and the lower side of the reinforcing member 203 (corresponding to Supplementary Note 4).
That is,
The clamping is done by the magnetic attraction force. (Corresponding to Appendix 5)
The front part 21 and the back part 22 are button-shaped magnets 24. The front and back of the mask 200 are sandwiched between the front part 21 and the back part 22 to fix the mask contact device 100.

That is,
The fixing means 2 can be separated into a front part 21 and a back part 22 (corresponding to Appendix 7).
That is,
The reinforcing means 1 is configured to sandwich the nose side surface 303 by elasticity (corresponding to appendix 12).
The reinforcing means 1 is made of stainless steel, which is an elastic material similar to that used in paper clips. The elastic material used in the reinforcing means is sometimes referred to as a reinforcing means elastic material 11.
It is constructed by bending a wire rod with a diameter of 0.7 mm into a pentagon with one side missing. There is no particular restriction on the shape as long as it can reliably hold the side of the nose 300, but this shape is used because the end of the reinforcing means 1 is approximately perpendicular to the side of the nose 300. The front part 21 is attached to the end of the reinforcing means 1 with an epoxy adhesive. The front part 21 is a button-shaped magnet 24. The joining method may be to drill a cylindrical hole in the button-shaped magnet 24 and fit it into the end of the reinforcing means 1, or to weld it. The reinforcing means 1 is biased so that both ends of the reinforcing means 1 are closed, in other words, in the direction in which the length of the missing side becomes shorter.

That is,
If a reinforcing member 203 of the mask 200 is present, the reinforcing means 1 is located along the reinforcing member 203 at at least one of the positions above the reinforcing member 203 and the position below the reinforcing member 203 (corresponding to Appendix 13).
That is,
The reinforcing means 1 is located on the front side 201 of the mask 200 (corresponding to Appendix 14).
Next, the operation of the embodiment configured as above will be described.
The elasticity of the reinforcing means 1 can be adjusted to some extent by adjusting the angle of the corner located farthest from the pentagonal mask 200.
Once the mask 200 is worn, a position where the reinforcing means 1 pinches the nose side surface 303 is selected. At this time, a mark or the like may be made. The mask 200 is removed from the body, and the tip of the reinforcing means 1 is opened so that the front part 21 is located at the selected position, and the front part 21 is placed against the front side 201 of the mask 200. In this state, the back part 22 is attached to the back side 202 by magnetic force. Then, the mask fitting device 100 is fixed. With the mask fitting device 100 fixed, the mask 200 is worn. If necessary, the position of the reinforcing means 1 is finely adjusted. In this case, the position of the back part 22 must also be adjusted, but the back part 22 can be moved by inserting a finger between the mask 200 and the face, for example.
With this configuration, the reinforcing means 1 pinches the nose side 303, which has the effect of reliably suppressing the portion where the nose 300 begins to extend from the face (the corners of the face that extend left and right from the nose side 303), which is particularly prone to gaps.
When removing the mask contact device 100 from the mask 200, the magnet 24 which is the back portion 22 is simply moved away from the back side 202.
During storage, it is convenient to store the front portion 21 and the back portion 22 in a joined state.

As described above, according to the mask fitting device 100 of this embodiment, the reinforcing means 1 presses the upper part of the mask 200, so that the upper part of the mask 200 can be fitted more closely.

Next, an eleventh embodiment will be described.
In the tenth embodiment described above, the reinforcing means 1 is provided on the front surface of the mask 200, whereas in the eleventh embodiment, the reinforcing means 1 is provided around the nose 300 at the nose bridge 301. In other words, the reinforcing means 1 is provided above the mask 200.
FIG. 37 shows the reinforcing means 1 bent upward (rear view).
The reinforcing means 1 is made of stainless steel, an elastic material similar to that of a paper clip. It is constructed by bending a wire rod with a diameter of 0.7 mm into a V-shape close to a U. When in use, the V-shape is upside down. In other words, it is a Λ-shape. The left side of the two diagonal lines constituting Λ is biased to rotate counterclockwise around the apex. The right side is biased in the opposite direction. In other words, when the reinforcing means 1 is hung on the nose 300, it is configured to pinch the nose by rotating in opposite directions. The front part 21 is a button-shaped magnet 24, and is fixed so that it faces the inside of the two lines constituting Λ. The axis of the cylinder of the button-shaped magnet 24 is attached so that it faces slightly forward in the figure than the surface constituting Λ. In this embodiment, an angle adjustment means is provided, and the angle at which the button-shaped magnet 24 faces the front side with the diagonal line as an axis can be adjusted. The front part 21 may be fixed to the reinforcing means 1 by a universal joint so that the front part 21 can effectively hold the mask 200. The rest is the same as in the tenth embodiment.

That is,
The reinforcing means 1 is deformable and retains its shape once deformed (corresponding to appendix 12).
It is also possible to use the following.

As described above, with the mask fitting device of this embodiment, the reinforcing means presses the upper part of the mask, allowing the upper part of the mask to fit more closely.

Next, a twelfth embodiment will be described.
In the tenth and eleventh embodiments described above, it is necessary to suck the back parts 22 one by one. In contrast, the tenth embodiment is provided with a guide means 6, which makes it easier to fix the front part 21 and the back part 22 together.
FIG. 38 shows the guide means 6 (front view).
The reinforcing means 1 and the front portion 21 are constructed in the same manner as in the tenth embodiment.

That is,
The fixing means 2 fixes the mask 200 by sandwiching the front side 201 and the back side 202 of the mask 200 (corresponding to Supplementary Note 3).
That is,
The mask fitting device 100 is
In the case where the mask 200 has a reinforcing member 203,
Based on the wearing state of the mask 200,
The position where the front side 201 and the back side 202 are sandwiched is the upper side of the reinforcing member 203 (corresponding to Appendix 4).
That is,
The clamping is done by the magnetic attraction force (corresponding to Appendix 5).
That is,
The fixing means 2 can be separated into a front part 21 and a back part 22 (corresponding to Appendix 7).
That is,
The reinforcing means 1 is configured to pinch the nose side surface 303 by elasticity (corresponding to appendix 12).
That is,
If a reinforcing member 203 of the mask 200 is present, the reinforcing means 1 is located below the reinforcing member 203 (corresponding to Appendix 13).
That is,
The reinforcing means 1 is located on the front side 201 of the mask 200 (corresponding to Appendix 14).
That is,
having a guide means 6 arranged in the nose 300,
The guide means 6 has a back part 22,
The front portion 21 is guided to a fixed position.
The fixing position is a position where the reinforcing means 1 is fixed by the front part 21 and the back part 22.

FIG. 38 shows the basic configuration.
The guide means 6 has a Λ-shaped stainless steel wire (hereinafter referred to as the Λ-shaped member). The Λ-shaped member is an elastic body with a diameter of 0.7 mm. It is slightly biased so that the opening below Λ narrows, making it easier to temporarily attach it to the nose 300. The left and right diagonal lines that make up Λ have triangular or trapezoidal members (hereinafter referred to as flag-shaped members) that are triangular or trapezoidal close to a triangle so as to widely cover the side surface of the nose 300, and a magnet 24, which is the back portion 22, is built into this. The surface 61 of the flag-shaped member on the nose 300 side is

That is,
Prevents at least one of the outflow of exhaust air and the inflow of outside air due to inhalation between the upper part of the mask 200 and the face (corresponding to Appendix 25)
Also, it is configured with a smooth curved surface to absorb the step caused by the thickness of the magnet 24. For this point, please refer to the description of the breath leakage prevention means in the fourth embodiment. The flag-shaped member has a back position adjustment means 61, which allows it to rotate around the wire as an axis. Also, the position can be adjusted in the diagonal line direction of Λ. This will be explained in detail below.

FIG. 39 shows a guide means 6 (perspective view) for Westerners, etc.
Generally, the part where the nose 300 connects to the forehead is about the same height as the nose bridge 301. However, both sides of the nose bridge 301 at the same position, that is, the direction of the eyes, are greatly concave. Therefore, for individuals with deep facial features such as Westerners, with a simple Λ-shape, there is a concern that the guide means 6 cannot be temporarily fixed efficiently, or that the position of the Λ-shaped member is generally forward, causing the back portion 22 to come forward and making it impossible to hold the back of the side of the nose 300. The illustrated form solves this problem. The back portion position adjustment means 61 clamps the entire wire, but for convenience of explanation, the upper end or the lower end of the flag-shaped member is illustrated as the back portion position adjustment means 61.

FIG. 40 is a cross-sectional view taken along the line A-A'. The flag-shaped member has a teardrop shape in cross section that is close to an isosceles triangle. It has a flag-shaped member front and a flag-shaped member back, and is connected by a hinge 64 so that it can be opened and closed. The flag-shaped member front and flag-shaped member back are fixed by a hook 65 provided on a part of the inside side so that they do not open normally. In the figure, the upper side is the flag-shaped member back, and the lower side is the flag-shaped member back. A magnet 24, which is the back part 22, is attached to the back of the flag-shaped member (not shown). The back of the flag-shaped member has a wire lateral direction restricting means that presses the wire of the Λ-shaped member horizontally and against the inside side of the flag-shaped member. In addition, the back of the flag-shaped member has a wire vertical direction restricting means that presses the wire of the Λ-shaped member vertically and against the inside side of the flag-shaped member. These press the wire of the Λ-shaped member against the flag-shaped member. Therefore, the flag-shaped member clamps the wire of the Λ-shaped member. The wire of the Λ-shaped member and the flag-shaped member are fixed by friction, so the flag-shaped member can move forward and backward as shown in the figure, and can also rotate around the wire of the Λ-shaped member.
The surface constituting the back of the flag-shaped member (hereinafter sometimes referred to as the prevention surface) is

That is,
Prevents at least one of the outflow of exhaust air and the inflow of outside air due to inhalation between the upper part of the mask 200 and the face (corresponding to Appendix 25)
That is,
The guide means 6 is hooked onto the nose bridge 301 and temporarily fixed (corresponding to Appendix 22).
For this, please refer to Figures 44 and 46. Note that the term "temporarily fixed" includes cases where the device is not completely fixed but is assisted by a hand or the like. In other words, it also includes cases where the device is easier to hold than when it is supported only by a hand or the like.

That is,
The guide means 6 has a back portion position adjustment means 61 for adjusting the position of the back portion 22 (corresponding to Supplementary Note 23).
That is,
The guide means 6 converts the force of the reinforcing means 1 pinching both sides of the nose 300 and pinches the nose side surface 303, or reinforces the pinching force (corresponding to Appendix 24).
Although the guide means 6 itself also pinches the nose 300 for temporary fixation, the reinforcing means 1 pinches both sides of the nose 300, so that the nose 300 is pinched with even stronger force. The apex of the Λ-shaped member may be a hinge that does not open beyond a certain angle.

That is,
The guide means 6 has a surface, and the surface is arranged at least on the nose side surface 303, and prevents at least one of the outflow of exhaust air and the inflow of outside air due to inhalation from between the upper part of the mask 200 and the face. (Corresponding to Supplementary Note 25)
This can further reduce the inflow of dust and the like into the mask 200 (see FIG. 42).

Next, the operation of the embodiment configured as above will be described.
43 shows a mask having a guide means 6 (a state in which the reinforcing means 1 and the guide means 6 are joined together). Inside the mask 200, the front part 21 and the back part 22 are joined together in this manner. Description will be given with this in mind.

Figure 45 shows the guide means 6 (temporarily fastened front). It can be seen that the prevention surface is in close contact with the nose side 303, preventing breath leakage from the guide part and the nose side 303. In addition, both flag-shaped members are lightly pressed against the nose side 303. Also, since the guide means 6 is Λ-shaped when viewed from the front in the figure, it can be seen that it is relatively difficult to fall off because the nose 300 enters the corner side of the apex of Λ when it moves downward. The intended fixing position is adjusted by the rear position adjustment means 61.
In this state, the mask 200 is put on. At that time, the guide means 6 protruding from the mask 200 is held by hand to prevent the guide means 6 from coming off or shifting (see FIG. 47).
The left and right front portions 21 are attracted to the back portions 22 of the guide means 6 by magnetic force.

In the tenth embodiment, the position of the fixing means 2 of the back part 22 is fixed by frictional force caused by the force of the front part 21 and the back part 22 pinching the mask 200. However, when the reinforcing means 1 strongly pinches the nose side surface 303, there is a risk that the nose side surface 303 may shift from the face side toward the nose bridge 301. This is mainly because the nose cross section is wedge-shaped and the nose side surface 303 forms a slope.
However, the configuration of this embodiment has the effect of preventing the fixing means 2 from shifting. If it is desired to more firmly prevent shifting, the wire material of the Λ-shaped member can be made thicker so that it is not easily deformed. In that case, the Λ-shaped member is deformed in advance to match the position of the individual's preference. In particular, the opening at the bottom of the Λ-shaped member is adjusted.
When removing the mask fitting device 100, the magnetic force between the front portion 21 and the back portion 22 is released, and the reinforcing means 1 is separated from the guiding means 6.
Figure 47 shows the state in which the mask having the guide means 6 is worn. It can be seen that the reinforcing means 1 having elasticity strongly presses the nose side surface 303. In addition, since the upper part of the Λ-shaped member protrudes from the mask 200, there is an effect that the mask fitting device 100 and the mask 200 can be easily worn.

As described above, with the mask fitting device of this embodiment, the reinforcing means presses the upper part of the mask, allowing the upper part of the mask to fit more closely.

Next, a thirteenth embodiment will be described.
In the twelfth embodiment described above, the guide means 6 is hooked onto the bridge of the nose 301 and temporarily fixed thereto, whereas in the thirteenth embodiment, the guide means 6 is hooked onto the ala of the nose 302 and temporarily fixed thereto.
FIG. 48 shows the guide means 6 resting on the nasal ala 302 (upper front view).

That is,
The guide means 6 is hooked onto the nose wing 302 and temporarily fixed thereto (corresponding to Appendix 22).
The guide means 6 has a wire rod (hereinafter referred to as a U-shaped member) formed by rotating a U by 90 degrees clockwise. When the upper and lower lines of the U are extended, they intersect to form an isosceles triangle. The base angle is configured so that the upper and lower lines run along the base of the side of the nose 300. As in the twelfth embodiment, the upper and lower lines of the U have a flag-shaped member. The flag-shaped member has a back portion 22 which is a magnet 24. When a position adjustment means is provided, it can be configured in the same manner as in the twelfth embodiment.

FIG. 49 shows the guide means 6 hanging on the nasal ala 302 (temporarily attached front view).
With this configuration, even if the face is deeply carved, the shape of the guide means 6 does not need to be changed regardless of the height of the part where the forehead and the nasal bridge 301 are connected. In addition, since the guide means 6 cannot be seen from the outside of the mask 200, there is an effect of a good appearance.
Also, a length adjustment means for the connecting portion 63 may be provided to adjust the length of the connecting portion 63. This makes it possible to accommodate individual differences in the width of the nose 300, particularly the width of both nostrils 302.
The operation of this embodiment is almost the same as that of the twelfth embodiment, and therefore a detailed description is omitted.

As described above, with the mask fitting device of this embodiment, the reinforcing means presses the upper part of the mask, allowing the upper part of the mask to fit more closely.

Next, a fourteenth embodiment will be described.
The thirteenth embodiment described above does not have an air securing means, but the fourteenth embodiment has an air securing means.
FIG. 50 is an explanatory view (perspective view) of the air securing means.

That is,
The space securing means 5 extends from the guide means 6 and secures a space 51 for intake air. (Corresponding to Supplementary Note 26)
The thirteenth embodiment had a U-shaped member. The part of the U-shaped member that corresponds to the vertical bar was placed under the nose 300, near the nasal opening of the nose 300. The part that corresponds to the vertical bar, i.e., the connecting part 63, is enlarged and shaped so that it returns around the mouth. The part that corresponds to the connecting part 63 is a wire that is roughly teardrop-shaped. Hereinafter, this member will be referred to as the teardrop-shaped member. As in the thirteenth embodiment, a flag-shaped member is provided at the end of the teardrop-shaped member. The flag-shaped member has a back position adjustment means 61 with a similar mechanism to that of the twelfth embodiment. A space securing means 5 is provided on the front of the teardrop-shaped member.
Fig. 106 shows a conventional space securing means 5. This lifts the part of the mask 200 that mainly touches the mouth and reduces the feeling of breathlessness caused by the mask 200 sticking to the face when inhaling.
FIG. 50 is an explanatory view (perspective view) of the air securing means.
It is placed on the curved portion of the teardrop-shaped member. The air securing means is attached to the teardrop-shaped member at the left and right parts when viewed from the front, and the vertical position of the teardrop-shaped member can be adjusted. For example, a mechanism that clamps the wire of the teardrop-shaped member, like the rear position adjustment means 61, can be provided. However, this is to compensate for individual differences, and once it is adjusted, it is not usually necessary to adjust it.
The portion of the water-drop shaped member where the space securing means 5 is arranged and the portion connecting the flag shaped member function as a connecting portion 63 .
As another configuration, a wire may be extended from both sides of the space securing means 5 and engaged with the flag portion. However, the difference is in the expression whether the wire extends from the guide portion or the space securing means 5.

The reinforcing means 1 is a partially missing circle, i.e. an arc, but it can also be other shapes. In short, it is sufficient if it can effectively press the nose side surface 303 with elastic force. The reinforcing means 1 is a stainless steel elastic wire. The diameter of the wire is 7 mm. The front part 21 and the back part 22 are magnets 24.

Next, the operation of the embodiment configured as above will be described.
While supporting the space securing means 5 with the hand, the mask fitting device 100 is temporarily fixed. At that time, the position of the flag-shaped member is adjusted by the back part position adjustment means 61 so that the back part 22 is in an appropriate position. The mask fitting device 100 is temporarily fixed to the nose 300, but since there is a possibility that the weight of the space securing means 5 cannot be supported, the space securing means 5 is supported by the hand. In this state, the mask 200 is worn. While spreading the tip of the fixing means 2, the front part 21 and the back part 22 are attracted by magnetic force. When the attraction of both fixing means 2 is completed, the mask fitting device 100 is fixed to the mask 200. With this configuration, the size of the space securing means 5 is large, so that it is easy to hold by hand and the mask fitting device 100 is easy to wear. In addition, when the space securing means 5 is provided separately, a string or the like is required to fasten the space securing means 5 to the ear, but this is unnecessary.
When removing the mask contact device 100, the magnetic coupling between the front portion 21 and the back portion 22 is released, and the reinforcing means 1 is separated from the mask 200, as in the previous embodiment.

As described above, with the mask fitting device of this embodiment, the reinforcing means presses the upper part of the mask, allowing the upper part of the mask to fit more closely.

Next, a fifteenth embodiment will be described.
In the twelfth and thirteenth embodiments described above, the reinforcing means 1 is a reinforcing means elastic body 11, whereas in the fifteenth embodiment, the reinforcing means 1 is deformable and once deformed, it retains its shape.

FIG. 51 shows the reinforcing means 1 by shape retention (front view).
The reinforcing means 1 is made of soft iron, which is a magnetic material, and can be freely deformed in shape.
Therefore, the place where the back portion 22 is adsorbed becomes the front portion 21. If the back portion 22 is adsorbed relatively below the reinforcing means 1, the reinforcing means 1 will be located above the mask 200. Also, if the back portion 22 is adsorbed relatively above the reinforcing means 1, the reinforcing means 1 will be located below the mask 200. In other words, the vertical position of the reinforcing means 1 relative to the mask 200 can be adjusted by the place where the back portion 22 is adsorbed. Similarly, the lateral position of the reinforcing means 1 relative to the mask 200 can be adjusted by the place where the back portion 22 is adsorbed.
The reinforcing means 1 has a length of 1.5 cm and a width of 7.5 cm. The range of dimensions is as described above.

That is,
The fixing means 2 fixes the mask 200 by sandwiching the front side 201 and the back side 202 of the mask 200 (corresponding to Supplementary Note 3).
That is,
In the case where the mask 200 has a reinforcing member 203,
Based on the wearing state of the mask 200,
The position where the front side 201 and the back side 202 are sandwiched is the lower side of the reinforcing member 203 (corresponding to Appendix 4).
That is,
The clamping is done by the magnetic attraction force. (Corresponding to Appendix 5)
That is,
The reinforcing means 1 is deformable and retains its shape once it is deformed. (Corresponding to Appendix 12)
That is,
If a reinforcing tool 203 of the mask 200 is present, the reinforcing means 1 is located along the reinforcing tool 203 at any one of the positions above the reinforcing tool 203, below the reinforcing tool 203, and overlapping the reinforcing tool 203 (corresponding to Appendix 13).
That is,
The reinforcing means 1 is located on the front side 201 of the mask 200 (corresponding to Appendix 14).
Incidentally, if the positions of the guide means 6 and the reinforcing means 1 with respect to the mask 200 are reversed, it is also possible to configure the reinforcing means 1 to be located behind the mask 200 .

That is,
The mask fitting device 100 has a vertical position adjustment means 26 for adjusting the vertical position of the reinforcing means 1 relative to the fixing means 2 (based on the state in which the mask 200 is worn) [corresponding to appendix 15]
That is,
The mask fitting device 100 has a left-right position adjustment means 27 for adjusting the left-right position of the reinforcing means 1 relative to the fixing means 2 (based on the state in which the mask 200 is worn) [corresponding to appendix 16]
The guide means 6 has the same configuration as in the twelfth embodiment.

That is,
having a guide means 6 arranged in the nose 300,
The guide means 6 has a back part 22,
The front portion 21 is guided to a fixed position.
The fixing position is a position where the reinforcing means 1 is fixed by the front part 21 and the back part 22.
That is,
The mask fitting device 100 is characterized in that the guide means 6 is hooked onto at least one of the nose bridge 301 and the nose wings 302 and temporarily fixed thereto (corresponding to appendix 22).

The configuration in which the nose wing 302 is hooked and temporarily fixed to at least one side can be achieved by using the guide means 6 of the 13th embodiment. It is also possible to use a combination of the guide means 6 of the 12th and 13th embodiments. A connecting means 63 for connecting both connecting parts 63 can be provided in the flag-shaped member. Specifically, the rear position adjustment means 61 of the 12th embodiment is designed so that a wire can be inserted from both the top and bottom, so the Λ-shaped member can be inserted from above and the U-shaped member can be inserted from below.

That is,
The mask fitting device 100 is characterized in that the guide means 6 has a back portion position adjustment means 61 for adjusting the position of the back portion 22 (corresponding to Appendix 23).
The guide means 6 has the same configuration as in the twelfth embodiment.
A description of the operation of the embodiment configured as above will be omitted.

As described above, with the mask fitting device of this embodiment, the reinforcing means presses the upper part of the mask, allowing the upper part of the mask to fit more closely.

Next, a sixteenth embodiment will be described.
In the twelfth embodiment described above, the back portion 22 of the guide means 6 is a magnet 24, whereas in the sixteenth embodiment, a magnetic body that is attracted to the magnet 24 is used instead of the magnet 24.
FIG. 54 shows a separation type in which the guide means 6 is made of a magnetic material (top view of the combined state of the reinforcing means 1 and the guide means 6).

The guide means 6 is made of magnetic soft iron and can be freely deformed in shape.
Therefore, the place where the front portion 21 is adhered becomes the back portion 22 .

If the front portion 21 is attracted to a position below the guide means 6, the guide means 6 will be located above the mask 200. Also, if the front portion 21 is attracted to a position above the guide means 6, the guide means 6 will be located below the mask 200. In other words, the vertical position of the guide means 6 with respect to the mask 200 can be adjusted depending on the location to which the front portion 21 is attracted. Similarly, the left-right position of the guide means 6 with respect to the mask 200 can be adjusted depending on the location to which the front portion 21 is attracted.
The guide means 6 has a length of 1.5 cm and a width of 7.5 cm. The range of dimensions is the same as that of the reinforcing means 1 of the fifteenth embodiment.
The reinforcing means 1 has the same configuration as that in the twelfth embodiment.

That is,
The fixing means 2 fixes the mask 200 by sandwiching the front side 201 and the back side 202 of the mask 200 (corresponding to Supplementary Note 3).
That is,
In the case where the mask 200 has a reinforcing member 203,
Based on the wearing state of the mask 200,
The position where the front side 201 and the back side 202 are sandwiched is either the upper side or the lower side of the reinforcing member 203 (corresponding to Appendix 4).
That is,
The clamping is done by the magnetic attraction force. (Corresponding to Appendix 5)
That is,
The fixing means 2 can be separated into a front part 21 and a back part 22 (corresponding to Appendix 7).
That is,
The reinforcing means 1 is configured to sandwich the nose side surface 303 by elasticity (corresponding to appendix 12).
That is,
If a reinforcing member 203 of the mask 200 is present, the reinforcing means 1 is located along the reinforcing member 203 at one of the positions above the reinforcing member 203 and below the reinforcing member 203 (corresponding to Appendix 13).
That is,
The reinforcing means 1 is located on the front side 201 of the mask 200 (corresponding to Appendix 14).
That is,
The mask fitting device 100 is
The reinforcing means 1 is provided with a vertical position adjustment means 26 for adjusting the vertical position of the reinforcing means 1 relative to the fixing means 2 (based on the state in which the mask 200 is worn) (corresponding to Appendix 15).
That is,
The mask fitting device 100 is
The reinforcing means 1 is provided with a left-right position adjustment means 27 for adjusting the left-right position of the reinforcing means 1 relative to the fixing means 2 (based on the state in which the mask 200 is worn) (corresponding to Appendix 16).
That is,
The mask fitting device 100 is
having a guide means 6 arranged in the nose 300,
The guide means 6 has a back part 22,
The front portion 21 is guided to a fixed position.
The fixing position is a position where the reinforcing means 1 is fixed by the front part 21 and the back part 22 (corresponding to Supplementary Note 21).
With this configuration, the guide means 6 can be freely deformed, which has the effect of making it easy to fit the face. It is preferable that the guide means 6 is covered with a soft material such as vinyl.
A description of the operation of the embodiment configured as above will be omitted.

As described above, with the mask fitting device of this embodiment, the reinforcing means presses the upper part of the mask, allowing the upper part of the mask to fit more closely.

Next, a seventeenth embodiment will be described.
In the sixteenth embodiment described above, the guide means is a magnetic plate, but in this embodiment, the back of the guide means is made of a magnet and is covered with a soft material.
FIG. 56 shows a rectangular guide means (front view in extended state)
The reinforcing means 1 used is that of the twelfth embodiment.
The guide means 6 is made of vinyl and shaped like cylinders of slightly different sizes, with the smaller cylinder inserted into the larger cylinder. Therefore, there is a double overlap inside. To prevent the two cylinders from coming apart, a string is provided inside to tie both ends together, regulating the maximum length by which the smaller cylinder extends from the larger cylinder. The position of the smaller cylinder relative to the larger cylinder is fixed by friction. This configuration allows the length to be adjusted.
This functions as the back position adjustment means 61 .
The dimensions are 1 cm in length, 8 cm in width when expanded, and 5 cm in width when contracted. The dimensional range is the same as that of the reinforcing means 1 of the fifteenth embodiment.

The polar directions of the left and right magnets 24 are reversed. Therefore, when the guide means 6 is bent, the left and right are attracted to each other (see FIG. 94). With this configuration, when the mask fitting device 100 is not used, the guide means 6 can be substituted for a clip or the like.
Another example of the back position adjustment means 61 may be a hook-and-loop fastener, with the left half being one side of the hook-and-loop fastener and the right half being the other side of the hook-and-loop fastener.

That is,
The fixing means 2 fixes the mask 200 by at least one of sandwiching the front side 201 and the back side 202 of the mask 200 and piercing the mask 200 (corresponding to Supplementary Note 3).
That is,
In the case where the mask 200 has a reinforcing member 203,
Based on the wearing state of the mask 200,
The position where the front side 201 and the back side 202 are sandwiched is either the upper side or the lower side of the reinforcing member 203 (corresponding to Appendix 4).
That is,
The clamping is done by the magnetic attraction force. (Corresponding to Appendix 5)
That is,
The fixing means 2 can be separated into a front part 21 and a back part 22 (corresponding to Appendix 7).
That is,
If a reinforcing member 203 of the mask 200 is present, the reinforcing means 1 is located along the reinforcing member 203 at a position above the reinforcing member 203 or below the reinforcing member 203 (corresponding to Appendix 13).
That is,
The reinforcing means 1 is located on the front side 201 of the mask 200 (corresponding to Appendix 14).
That is,
The mask fitting device 100 is
having a guide means 6 arranged in the nose 300,
The guide means 6 has a back part 22,
The front portion 21 is guided to a fixed position.
The fixing position is a position where the reinforcing means 1 is fixed by the front part 21 and the back part 22 (corresponding to Supplementary Note 21).
That is,
The guide means 6 has a back portion position adjustment means 61 for adjusting the position of the back portion 22 (corresponding to Supplementary Note 23).
That is,
The guide means 6 converts the force with which the reinforcing means 1 pinches both sides of the nose 300, and pinches the nose side surface 303 (corresponding to Appendix 24).

With this configuration, the guide means 6 can be simply configured. In particular, the number of metal members is small, which has the effect of improving safety.
A description of the operation of the embodiment configured as above will be omitted.

As described above, with the mask fitting device of this embodiment, the reinforcing means presses the upper part of the mask, allowing the upper part of the mask to fit more closely.

Next, an eighteenth embodiment will be described.
In the twelfth embodiment described above, individual differences are adjusted by the rear position adjustment means 61, whereas in the eighteenth embodiment, individual differences are adjusted by the user processing the guide means 6.
FIG. 59 shows the guide means 6 which can be processed (upper front view).
The guide means 6 is made of cardboard and has the shape of an isosceles trapezoid with the upper base shorter than the lower base. When in use, the guide means 6 is bent from the center, i.e. the axis of symmetry, to follow the angle of the slope of the nose 300. There are magnets 24, which are the backs 22, near both ends of the lower base. It is preferable to configure the legs of the trapezoid so that they fit the line formed by the face and the base of the nose 300.
FIG. 60 shows a possible processing of the guide means 6 (developed view, rear view).
The back 22 is a button-shaped magnet 24. The bottom surface of the magnet 24 is attached with double-sided tape, which makes it convenient for the user to assemble.

The guide is assembled by folding a rectangular piece of cardboard. First, the horizontal center of the rectangle is pressed against the user's nose 301 as shown in the figure. Then, the cardboard is deformed to fit the shape of the nose 300. Then, the shape of the cardboard can be used to determine which parts of the trapezoid should be the legs. This is the diagonal dashed line shown in the figure. Both ends of the rectangle are folded along the diagonal dashed line to form a trapezoid. In this state, place it on the face to check whether the folding location is appropriate. If it is not appropriate, readjust the folding and place it on the face to check. The folding is then reversed, the double-sided tape of the magnet 24 is removed, and the magnet 24 is fixed in an appropriate position. In the figure, the part to be folded is a right-angled triangle with the narrowest corner pointing downward. Apply adhesive or the like to this part, and fold the dashed line into a valley fold to fix it.
Figure 61 shows a guide means 6 that can be processed (temporarily fixed front side). In the figure, both base corners of the trapezoid are cut off so that they do not come into contact with the face and irritate it.
The reinforcing means 1 is the same as that in the twelfth embodiment.

That is,
The fixing means 2 fixes the mask 200 by at least one of sandwiching the front side 201 and the back side 202 of the mask 200 and piercing the mask 200 (corresponding to Supplementary Note 3).
That is,
In the case where the mask 200 has a reinforcing member 203,
Based on the wearing state of the mask 200,
The position where the front side 201 and the back side 202 are sandwiched is either the upper side or the lower side of the reinforcing member 203 (corresponding to Appendix 4).
That is,
The mask fitting device 100 is
The clamping is done by the magnetic attraction force. (Corresponding to Appendix 5)
That is,
The fixing means 2 can be separated into a front part 21 and a back part 22 (corresponding to Appendix 7).
That is,
The reinforcing means 1 is at least one of a deformable shape that is retained once deformed, and a shape that is elastically sandwiched between the nose side surface 303 (corresponding to appendix 12).
In this embodiment, either method can be appropriately selected by selecting the reinforcing means 1. For example, if both types of reinforcing means 1 are provided, both types of sandwiching methods will be available.

That is,
A mask fitting device 100 characterized in that, if a reinforcing tool 203 of a mask 200 is present, the reinforcing means 1 is located along the reinforcing tool 203 at at least one of the positions above the reinforcing tool 203, the position below the reinforcing tool 203, and the position overlapping the reinforcing tool 203 (corresponding to appendix 13).
That is,
The reinforcing means 1 is located on the front side 201 of the mask 200 (corresponding to Appendix 14).
That is,
The mask fitting device 100 is
having a guide means 6 arranged in the nose 300,
The guide means 6 has a back part 22,
The front portion 21 is guided to a fixed position.
The fixing position is a position where the reinforcing means 1 is fixed by the front part 21 and the back part 22 (corresponding to Supplementary Note 21).
That is,
The guide means 6 is hooked and temporarily fixed to the nose bridge 301 (corresponding to Appendix 22).
That is,
The guide means 6 converts the force of the reinforcing means 1 pinching both sides of the nose 300 and pinches the nose side surface 303, or reinforces the pinching force (corresponding to Appendix 24).
That is,
The guide means 6 has a surface, and the surface is arranged at least on the nose side surface 303, and prevents at least one of the outflow of exhaust air and the inflow of outside air due to inhalation from between the upper part of the mask 200 and the face. (Corresponding to Supplementary Note 25)
The surface of the trapezoid that comes into contact with the nose 300 functions as a blocking surface.

By adopting such a configuration, there is an effect that the mask fitting device 100 can be provided at low cost.
In addition, since the entire nose 300 is covered, there is an advantage in that it is highly effective in preventing breath leakage.
In addition, the fold at the center of the trapezoid has the effect of reliably converting the force with which the reinforcing means 1 pinches the nose 300 on both sides.

In another embodiment, a rectangular member may be cut to fit an individual. In that case, the cut is made along the diagonal dashed lines on both sides. For the back 22, a flexible, cuttable, planar magnetic material may be used instead of the button magnet 24 (hereinafter, referred to as cuttable magnetic material). Examples of cuttable magnetic materials include rubber, plastic, etc., containing magnetic material. One example is a rubber magnet.
If the surface portion 21 is a magnet 24, the cuttable magnetic material does not need to be magnetic, and it is sufficient that it is attracted to the surface portion 21 at the very least.
For example, a tape-shaped rubber magnet is used as the cuttable magnetic material. The cuttable magnetic material is attached to the inside along the lower long side of a rectangular cardboard. The user cuts the cardboard along the diagonal dashed lines on both sides to form an isosceles trapezoid. The cuttable magnetic material is folded back from the center so that it is on the opposite side to the nose 300, and then attached to the nose 300. The cuttable magnetic material may be positioned anywhere else as long as it can effectively press the nose side surface 303 and fix the mask 200 with the back part 22 of the reinforcing means 1. For example, it may be arranged in a strip shape along the legs of the trapezoid on both sides. In these cases, it is more convenient to form the magnetic material into a trapezoid in advance rather than a rectangle.
A description of the operation of the embodiment configured as above will be omitted.

[Experimental Results]
(1) The degree of adhesion of the mask 200 was compared between when the mask adhesion device 100 was present and when it was not present.
The reinforcing member 203 was adjusted so that at least a part of the upper part of the mask 200 could be fitted closely to the face as much as possible even without the mask fitting device 100.
FIG. 72 shows the mask 200 in a folded state.
In this way, the mask 200 was folded in half from the center, and the reinforcing member 203 was biased.
FIG. 73 shows the state where it is aligned with the nose 300.
In this manner, the reinforcing member 203 was pressed firmly against the nasal bridge 301 and the nasal side surface 303.
Figure 74 shows the mask being worn (without the mask fitting device).
It can be seen that there is a large gap between the side of the nose 300 and the face.
FIG. 75 shows the gap (without a mask fitting device).
The object in the hand is the handle of a toothbrush. You can see that there is a gap on the left side of the front that is large enough to fit the handle of the toothbrush. The handle of the toothbrush is 13 mm wide and 4 mm thick. The dimensions of the toothbrush are the same in the following drawings.
FIG. 76 shows the gap (without a mask fitting device).
On the right side of the front, you can see that there is a gap large enough to fit a toothbrush handle.
FIG. 81 shows the gap (with a mask fitting).
This shows a state in which the mask close contact device 100 of the fifth embodiment is worn.
It is a little difficult to see in the figure because the reinforcing means 1 is angled slightly upward to go around the nose 300 and is attached to the upper side of the front part 21. However, it can be seen that the reinforcing means 1 pulls the upper side of the front part 21 toward the face more than the reinforcing tool 203 (wire).
FIG. 82 shows the gap (with a mask fitting).
This shows a state in which the mask close contact device 100 of the fifth embodiment is worn.
Since the reinforcing means 1 is located deeper than the thickness of the handle of the mask 200, the front part 21 is pushed further inward. The handle of the toothbrush does not fit into the gap between the mask 200 and the face.
FIG. 83 shows the gap (with a mask fitting and before opening and closing the mouth).
This is a state in which the mask close contact device 100 of the twelfth embodiment is worn. It can be seen that a depression occurs on the surface of the mask 200 that the front part 21 comes into contact with, and the mask 200 is pressed down significantly.

FIG. 78 shows the mouth open.
This is a state in which the mask fitting device 100 of the third embodiment is worn. The mouth is open. Since the fixing means 2 is in the center, both ends of the reinforcing means 1 are pulled down by the mask 200. However, it can be seen that the reinforcing means 1 firmly grips the nose 300, and the position of the mask 200 is maintained.

Figure 86 shows the mouth closed state (2).
This is a state in which the mask close contact device 100 of the twelfth embodiment is worn. This is a state in which the mouth is closed, continuing from Fig. 85. Even when compared with Fig. 84, it can be seen that the mask 200 has not shifted due to the mouth being open.
Figure 87 shows the mouth open position (2).
This is a state in which the mask close contact device 100 of the twelfth embodiment is worn. Continuing from Fig. 86, this is a state in which the mouth is open. It can be seen that even with the mouth open, the mask 200 is held by the mask close contact device 100, and the upper end of the mask 200 is hardly shifted downward.
Figure 88 shows the mouth closed state (3).
This is a state in which the mask close contact device 100 of the twelfth embodiment is worn. This is a state in which the mouth is closed, continuing from Fig. 87. Even when compared with Fig. 84 and Fig. 86, it can be seen that the mask 200 does not shift due to the mouth being open.

The above describes an embodiment of the mask fitting device 100 of the present invention, but the present invention is not limited to the described embodiment, and various modifications can be made within the scope of the claims.

For example, in the embodiment described above, the fixing means 2 and the reinforcing means 1 have different roles, but the reinforcing means 1 may also serve as the fixing means 2.
FIG. 89 shows that the fixing means 2 is caused by the resistance of the mask 200.
The mask fitting device 100 is shaped like an E rotated 90 degrees clockwise. It is made of a deformable soft iron plate. The horizontal bar in the center of the E pushes the center of the mask 200 forward as shown in the figure, and the upper and lower horizontal bars push the mask 200 backward, thereby fixing the mask fitting device 100.

That is,
This is achieved by the resistance force that causes the mask 200 to deform into the shape of the fixing means 2 and return to its original shape (corresponding to Appendix 5).
The vertical bar of E corresponds to reinforcing means 1,
That is,
The reinforcing means 1 is deformable and retains its shape once it is deformed. (Corresponding to Appendix 12)
By configuring in this manner, there is an effect that the mask close contact device 100 can be configured very simply.

In Figure 90, the fixing means 2 is due to the resistance of the mask 200. The mask fitting device 100 is made of stainless steel wire. It is an upside-down U-shaped object with a straight member attached perpendicular to the surface that makes up the U. The straight member pushes out the mask 200, and the vertical rods on both sides of the U push in the mask 200, thereby fixing the mask fitting device 100. The greater the forward protrusion of the straight member, the stronger the clamping force. Also, if there is a reinforcing member 203, the greater the protrusion of that part, the stronger the mask fitting device 100 can be fixed, so the straight member is convex toward the front to slightly increase the protrusion at the top.

FIG. 91 shows an application example of the reinforcing means 1.
In addition, the reinforcing means 1 is mainly described as being rectangular plate-like, which is deformable and retains its shape once deformed, but it may be configured to go around the nose bridge 301 from the nose bridge 301. The go-around part is Λ-shaped, and the nose 300 can extend forward from this part beyond the reinforcing means 1. With this configuration, the nose side 303 can be pressed by both oblique lines of the Λ shape, and the mask 200 can be tightly attached to the nose side 303.
FIG. 92 is an application example of the reinforcing means 1. In the fifth embodiment, the reinforcing means 1 was a wire, but the reinforcing means 1 in FIG. 91 is applied. The Λ-shaped part is a stainless steel wire, and it is possible to deform it to a certain extent while maintaining its strength. If the reinforcing means 1 is made into a rectangular plate, there is no means for adjusting the force applied to the upper long side and the force applied to the lower long side. By making the apex of Λ hit the area from the root of the nose to the nose back 301, a force can be applied to the reinforcing means 1 to rotate it around the longitudinal axis. Therefore, it is possible to finely adjust the force with which the reinforcing means 1 fits at least a part of the upper part of the mask 200 along the face. This is particularly effective when the fixing means 2 does not fix the center lines of the upper and lower sides of the reinforcing means 1.

FIG. 95 shows an application example in which the reinforcing means 1 pinches the nose side surface 303.
The reinforcing means 1 is an elastic wire rod with a U-shape turned upside down. The guide means 6 is a plate of soft iron, which is a magnetic material, and is flexible. The guide means 6 is rectangular. The end of the wire rod is firmly connected to the side of a cylindrical magnet 24. The magnet 24 is attracted to the guide means 6. However, if it is desired to fix this position firmly, another magnet 24 may be placed on the back side 202 of the guide means 6. The surfaces of the magnets 24 facing each other are poles that attract each other. The magnets 24 sandwich the guide means 6, so that the position of the back part 22 can be adjusted by the friction between the magnet 24 and the iron plate. In this case, the back part 22 is the position of the iron plate that attracts the magnet 24 attached to the reinforcing means 1.

That is,
The guide means 6 has a back portion position adjustment means 61 for adjusting the position of the back portion 22 (corresponding to Supplementary Note 23).
When the guide means 6 is brought to the front side 201 of the mask 200 , the iron plate of the guide means 6 described above functions as the reinforcing means 1 .
The iron plate is deformed by an elastic body of wire that is an upside-down U-shape, and is pressed against the nose side surface 303. It is also preferable to deform the iron plate so that it fits the face. The U-shaped reinforcing means elastic body 11 and the iron plate are fixed from the back side 202 by another cylindrical magnet 24.

That is,
The reinforcing means 1 is both deformable and retains its shape once deformed, and also has elasticity that pinches the nose side surface 303 (corresponding to appendix 12).

Instead of this magnet 24, the guide means 6 as in the twelfth embodiment can also be used (see FIG. 44). With such a configuration, the clamping force of the elastic body 23 can be transmitted to a plate-like member (the iron plate mentioned above), and the force can be applied over a wider range. If the clamping force of the reinforcing means elastic body 11 is only to be transmitted to a plate-like member, it does not have to be a magnetic material, and other flexible members, such as plastic plates, may be used. The guide means 6 described so far has been described as an example that performs other functions.

Fig. 96 shows an example (mask close contact device 100 alone) in which the fixing means 2 sandwiches the upper part of the mask 200, thereby securing the space 51. This shape is like turning the reinforcing means 1 part of the mask close contact device 100 explained in Fig. 89 inside out. The folded part is the upper side of the mask 200.
The vertical bar portion of E and the three horizontal bar portions of E firmly fix the mask fitting device 100 to the mask 200. The central horizontal bar of E protrudes greatly forward.
FIG. 97 is a conceptual diagram showing an example in which the fixing means 2 sandwiches the upper part of the mask 200 to secure the space 51 .
When the face is viewed from the side, the central horizontal bar of E is closer to horizontal than the nasal bridge 301, and pushes the mask 200 forward. This ensures a space 51 that makes breathing easier.
FIG. 98 shows an example in which the space securing means 5 extends from the fixing means 2 .

That is,
The mask fitting device 100 is
A space securing means 5 extends from at least one of the fixing means 2 and secures a space 51 for intake air. (Corresponding to Supplementary Note 19)

The end of the horizontal bar in the center of E is gradually widened to make it easier to secure the space 51. In this embodiment, the reinforcing means 1 corresponding to the vertical bar of E is not folded back against the upper side of the mask 200.
Consider an example in which the member in Fig. 98 is made of a magnetic material such as soft iron, is placed on back side 202, and is fixed from front side 201 with two button-shaped magnets 24. The vertical bar of the E functions as fixing means 2. Magnet 24 functions as front portion 21, and the position corresponding to magnet 24 functions as back portion 22. The position where magnet 24 is affixed may be the vertical bar of the E, or the horizontal bars above and below the E.
When the magnets 24 are attached at the upper and lower horizontal bars of the E, the two horizontal bars and the magnets 24 function as the vertical position adjustment means 26 .

That is,
The mask fitting device 100 is
The reinforcing means 1 is provided with a vertical position adjustment means 26 for adjusting the vertical position of the reinforcing means 1 relative to the fixing means 2 (based on the state in which the mask 200 is worn) (corresponding to Appendix 15).
When the magnet 24 is attached at the vertical bar position of the E, the vertical bar and the magnet 24 function as the left-right position adjustment means 27 .

That is,
The reinforcing means 1 is provided with a left-right position adjustment means 27 for adjusting the left-right position of the reinforcing means 1 relative to the fixing means 2 (based on the state in which the mask 200 is worn) (corresponding to appendix 16).
That is,
The mask fitting device 100 has a space securing means 5 extending from the reinforcing means 1 and securing a space 51 for inhalation. [Corresponding to Supplementary Note 19]
This configuration can be easily adopted in other embodiments in which the reinforcing means 1 is arranged on the back side 202.
In the configuration example of the fourth embodiment, the reinforcing means 1 can be disposed on the back side 202. The space securing means 5 may be extended from the reinforcing means 1.
In the configurations of the fifth and sixth embodiments, the reinforcing means 1 can be disposed on the back side 202. In that case, if the reinforcing means 1 and the fixing means 2 are both configured to support the space securing means 5, the space securing means 5 will extend from both the reinforcing means 1 and the fixing means 2.

That is,
If the fixing means 2 and the reinforcing means 1 are both supporting the space securing means 5, the space securing means 5 extends from the reinforcing means 1 and the fixing means 2. For example, this configuration can be easily achieved by using the fixing means 2 on the double clip of the seventh embodiment.

FIG. 100 shows Example 1 in which the reinforcing means 1 is curved.
FIG. 101 shows a second example in which the reinforcing means 1 is curved.
The reinforcing means 1 has been described as being deformable and retaining its shape once deformed, but there are cases where the reinforcing means 1 does not retain its shape well, in which case the shape retention can be reinforced using the techniques shown in Figures 100 and 101. In Figure 101, the force of the upper elastic body trying to return to its original shape is used to apply a force that bends the lower plate. The two plates are fixed by elastic fasteners 231. The bending force can be adjusted by adjusting the position of the elastic fasteners 231.

Figure 102 shows an example (mask fitting device 100 alone) where the reinforcing means 1 also doubles as the fixing means 2. It is made of stainless steel wire in an approximately M shape. The operating principle is the same as the mask fitting device 100 in Figure 98. However, there is no part that corresponds to the vertical bar of E that functions as the reinforcing means 1, and the entire M is held in a three-dimensionally bent state by

That is,
The sandwiching is performed by the resistance force that causes the mask 200 to return to the shape of the fixing means 2 after being deformed into the shape of the fixing means 2 (corresponding to Supplementary Note 5).
Also,
That is,
The reinforcing means 1 is deformable and retains its shape once it is deformed. (Corresponding to Appendix 12)

FIG. 103 shows an example (front view) in which the reinforcing means 1 also serves as the fixing means 2.
FIG. 104 shows an example (rear view) in which the reinforcing means 1 also serves as the fixing means 2.
However, in order to allow freedom of design and to effectively fit at least a portion of the upper part of the mask 200 to the face, it is desirable that the functions of the reinforcing means 1 and the fixing means 2 are separated as in the other embodiments.
The reinforcing means 1, the fixing means 2, the guide means 6 and other members may be combined in other suitable ways, and one may be used as a substitute for another.
