Further, as a first aspect of the helmet as described above, the interior body includes a hammock, the projection is provided on the hammock, and the helmet holds the ear straps with the projections of the hammock passing through the holes of the ear straps. will be explained.

Further, as a second aspect of the helmet as described above, the interior body includes a hammock, the protrusion is provided on the cap body, and the hammock holds the ear straps in a state where the protrusions of the hat penetrate through the holes of the ear straps. Describe the helmet.

FIG. 1 is a schematic diagram of a helmet 1 according to this embodiment. This helmet 1 includes a cap body 11 covering the wearer's head, an inner body 12 attached inside the cap body 11, and ear straps 13 attached to the cap body 11 or the inner body 12.例文帳に追加

Specifically, the ear straps 13 are composed of, for example, two straps corresponding to the left and right ears. Of these two strings, the two ends of the string corresponding to the left ear (hereinafter sometimes referred to as the left string) are attached to the left side of the cap body 11 or the inner body 12, and the right ear are attached to the right side of the cap body 11 or the inner body 12 .

Although not shown in FIG. 1, projections (1211, 1211a to 1211d) are provided on the cap body 11 or the inner body 12, and holes through which the projections pass are formed in the ear straps 13. , passes through the hole of the ear string 13. The cap body 11 and the inner body 12 are connected with the protrusions passing through the holes of the ear straps 13 .

Specifically, for example, two projections are provided on the left side of the cap body 11 or the inner body 12, near the front and near the back, while these two projections are provided at the two ends of the left string that constitutes the ear string 13. are formed with two holes through which . Two projections on the left side of the cap body 11 or the inner body 12 pass through two holes of the left string.

Two projections are provided on the right side of the cap body 11 or the inner body 12, near the front and near the back, and these two projections penetrate through the two ends of the right string that constitutes the ear string 13. Two holes are formed. Two projections on the right side of the cap body 11 or the inner body 12 pass through two holes of the right string.

All of the four protrusions are normally provided on either the inner body 12 or the cap body 11 . However, one or two or more of the four projections may be provided on the inner body 12 and the other one or two or more may be provided on the cap body 11 .

Alternatively, the ear straps 13 may be composed of one strap. Three holes are formed in both ends and the center of this one string, and three projections passing through these three holes are provided on the left side, the right side, and the rear side of the inner body 12 or the cap body 11, The three protrusions may pass through the three holes.

However, the configuration of the ear straps 13 is not limited. Moreover, the number and positions of the holes formed in the ear straps 13 are not limited. Furthermore, the number and positions of protrusions provided on the inner body 12 or the cap body 11 are not limited.

The number of holes formed in the ear straps 13 and the number of protrusions provided in the inner body 12 or the cap body 11 are usually the same, but may be different. For example, when two or more holes are formed in the ear strap 13, some of the two or more holes may not pass through any protrusions of the inner body 12 or the cap body 11. In the case where the body 12 or the hat body 11 is provided with two or more projections, some of the two or more projections do not have to pass through any holes of the ear straps 13 .

For example, when projections are provided on the inner body 12 as in the first aspect described later, the cap body 11 is attached to the ear straps 13 with the projections of the inner body 12 passing through the holes 131 of the ear straps 13 . hold down. Further, for example, when projections are provided on the cap body 11 as in the second aspect described later, the inner body 12 is configured such that the projections of the cap body 11 pass through the holes of the ear straps 13, and the ear straps are attached to the inner body 12. Hold 13.

The inner body 12 has a hammock 121 and a headband 122 . The hammock 121 is composed of, for example, three or more (four in FIG. 1) hanging bands each of which is connected at one end at one point. The coupling may be, for example, coupling by a coupling member such as a ring cord or bracket, or integral molding.

The other end of each of the three or more hanging bands is connected to each of the headband 122 and the cap body 11 . Specifically, the other end of each suspension band is coupled to the outer surface of the headband 122 as shown in FIG. . However, it does not matter which surface and position of each of the headband 122 and the hat body 11 the other end of each suspension band is connected. Thereby, the inner body 12 is constructed and results in the inner body 12 being attached inside the cap body 11 .

Each of the three or more suspension bands of the hammock 121 has a branch portion 121b that branches off and extends from the vicinity of the end portion (hereinafter simply referred to as "end portion") on the side that is coupled to the headband 122 and the like. have. The tip of each of the three or more branches 121 b is connected to the headband 122 . The tip of each branch portion 121 b is connected to the inner surface side of the headband 122 , for example, but may be connected to the outer surface side of the headband 122 . However, the branch portion 121b is not essential, and each of the three or more suspension bands may not have the branch portion 121b.

The connecting mechanism for connecting the cap body 11 and the inner body 12 may be, for example, a fixture such as a bracket or a screw, or may be an adhesive agent. Alternatively, the coupling mechanism may be an elastic body possessed by one or more of the inner body 12 and the cap body 11 . In other words, the cap body 11 and the inner body 12 may be combined as a result of pressing against each other by one or more elastic bodies possessed by at least one of them. Any coupling mechanism may be used as long as the cap body 11 and the inner body 12 are coupled as a result.

In the first aspect of the present embodiment, the projections (1211, 1211a to 1211c) are usually provided on the hammock 121 forming the inner body 12. As shown in FIG. However, the protrusion may be provided on the headband 122 that constitutes the inner body 12 .

In addition, the inner body 12 may further include a liner, for example. A liner is a shell-shaped impact absorbing member attached to the inner surface of the cap body 11 . For example, the projection may be provided on a liner that constitutes the inner body 12 or may be provided on any component of the inner body 12 .

Furthermore, although not shown in FIG. 1 , on the inner surface of the cap body 11 , for example, ridges are formed at positions corresponding to each of the three or more suspension bands of the hammock 121 . A ridge is an elongated projection. The ridges are, for example, longitudinal ribs (longitudinal ribs) indicated by reference numeral 111 in FIG. 3, but their length, shape and direction are not limited. Three or more (in the present embodiment, four) protrusions provided on the inner surface of the cap body 11 are hereinafter referred to as protrusions 111 . The ridges 111 have the effect of increasing the strength of the cap body 11 and also have the action of pushing the ear straps 13 toward the hammock 121 when the cap body 11 and the interior body 12 are coupled.

In addition, in a second aspect of the present embodiment, which will be described later, the projection (1211d) is provided on the cap body 11. As shown in FIG. The liner described above can also be considered part of the cap 11 .

(First aspect)
FIG. 2 is a diagram showing an example of a hammock 121 having projections. FIG. 2 shows the end of one of the three or more suspension bands forming the hammock 121 together with the ear straps 13 . In each of the other two or more suspension bands, the configurations of the ends and the ear straps 13 attached thereto are the same as those described below, but different ) can be used.

The ear straps 13 in this example are elongated rectangular (for example, tape-like) straps. A hole 131 is formed in the vicinity of the end of the ear string 13 . The vicinity of the end of the ear strap 13 is, for example, a position 10 mm to 20 mm from the end, but may be a position less than 10 mm from the end, or a position more than 20 mm from the end. The position of hole 131 with respect to the end of 13 does not matter. Further, the hole 131 is, for example, circular, but may be elliptical or polygonal such as rectangular or hexagonal. The circle or ellipse may not be a perfect circle or ellipse, and the polygon may have, for example, rounded corners.

Although the size of the hole 131 is, for example, 5 mm to 12 mm, it may be less than 5 mm or more than 12 mm, and the numerical value is not limited. Note that the maximum diameter is, for example, a diameter, a major axis, a diagonal length, or the like (the same shall apply hereinafter).

Hammock 121 includes protrusion 1211 and lateral hole 1212 . The projection 1211 is a columnar projection extending from the outer surface of the hammock 121 toward the inner surface of the hat body 11 . The columnar shape is, for example, a columnar shape, but may be an elliptical columnar shape or a polygonal columnar shape such as a square column or a hexagonal column.

The size of the columnar protrusion 1211 is, for example, in the range of 5 mm to 12 mm, preferably in the range of 8 mm to 10 mm, but may be less than 5 mm or more than 12 mm. Note that the size here is the maximum diameter of the upper surface of the protrusion 1211 .

That is, protrusion 1211 generally has a shape corresponding to the shape of hole 131 and a size corresponding to the size of hole 131 . However, as long as the protrusion 1211 can pass through the hole 131, one or more of the shape and size may be different.

The columnar projection 1211 is preferably slanted upward with respect to the normal to the outer surface of the hammock 121 . However, such an inclination is not essential, and the columnar projection 1211 may extend parallel to the normal to the outer surface of the hammock 121 (in other words, perpendicular to the outer surface). The height of the columnar protrusion 1211 is, for example, in the range of 5 mm to 10 mm, but it may be less than 5 mm or more than 10 mm, and the numerical value is not limited.

A groove 12111 is preferably formed at the tip of the columnar projection 1211 to engage with the above-described ridge 111 formed on the inner surface of the cap body 11 . However, the groove 12111 is not essential, and the tip of the columnar protrusion 1211 may be flat.

The lateral hole 1212 is a lateral elongated hole and is provided directly above the protrusion 1211 . The width of the lateral hole 1212 is the same as the width of the ear strap 13 or slightly larger than the width of the ear strap 13 . Also, the height of the horizontal hole 1212 is, for example, in the range of 2 mm to 3 mm, but any numerical value is acceptable as long as it is greater than the thickness of the ear strap 13 . With the protrusion 1211 of the hammock 121 passing through the hole 131 of the ear string 13 , the tip of the ear string 13 passes through the horizontal hole 1212 and is guided to the outer surface side of the hammock 121 .

However, the horizontal hole 1212 is not essential. For example, when using ear straps 13 that have holes 131 formed near their ends (see, for example, ear straps 13 shown in FIG. 4 below), the hammock 121 includes lateral holes 1212. It doesn't have to be.

When assembling the helmet 1 configured as described above, the assembling operator first passes the tips of the ear straps 13 through the horizontal holes 1212 of the hammock 121 . At that time, the assembling worker feeds the ear cords 13 into the lateral holes 1212 until the holes 131 of the ear cords 13 come to positions corresponding to the projections 1211 of the hammock 121 . In this state, when the assembling operator bends the ear strap 13 downward, the hole 131 of the ear strap 13 passes through the projection 1211 directed obliquely upward. Thereby, the ear straps 13 are connected to the hammock 121 .

Next, the assembler also connects the headband 122 to the hammock 121 to which the ear straps 13 are connected. Then, the assembling operator attaches the interior body 12 including the hammock 121 and the headband 122 to the inside of the hat body 11 . At that time, the assembling operator attaches the hammock 121 so that the groove 12111 formed at the tip of the projection 1211 of the hammock 121 engages with the ridge 111 formed on the inner surface of the cap body 11 .

As a result, the cap body 11 and the inner body 12 are joined together so that the cap body 11 presses the ear straps 13 while the projections 1211 of the hammock 121 pass through the holes 131 of the ear straps 13 .

FIG. 3 is a diagram showing a state in which the cap body 11 presses the ear straps 13 with the projections 1211 of the hammock 121 passing through the holes 131 of the ear straps 13 . In this example, the protrusion 111 (longitudinal rib) on the inner surface of the cap body 11 meshes with the groove 12111 of the protrusion 1211, so that the pressure from the cap body 11 is localized to the ear strap 13 via the protrusion 111 and the protrusion 1211. As a result, the ear straps 13 can be effectively prevented from coming off the hammock 121.例文帳に追加

(Modification 1 of the first aspect)
FIG. 4 is a diagram showing another example of a hammock 121 having protrusions. FIG. 4 shows the end of one of the three or more suspension bands forming the hammock 121 together with the ear straps 13 .

The ear string 13 in this example has a hole 131 formed near the end. The protrusion 1211 a is a columnar protrusion extending parallel to the normal to the outer surface of the hammock 121 . This columnar projection 1211a has a convex portion on the upper side of its side surface.

The hammock 121 in this example is provided with a panel 1214 that can be opened and closed via a hinge 1213 at a position corresponding to the protrusion 1211a of the hammock 121 . The hinge 1213 is formed with a slit 1213a through which the tip of the ear string 13 passes. The shape and size of the slit 1213a are not limited as long as the tip of the ear strap 13 can pass through the slit 1213a.

The panel 1214 is formed with a second hole 1214a through which the projection 1211a of the hammock 121 penetrates. The second hole 1214a may have any shape and size as long as the projection 1211a of the hammock 121 can pass through it.

The panel 1214 is closed with the tip of the ear string 13 passing through the slit 1213 a of the hinge 1213 and the protrusion 1211 a of the hammock 121 passing through the hole 131 of the ear string 13 . When the panel 1214 is closed, the protrusion 1211a passes through the second hole 1214a and the panel 1214 is locked by the protrusion of the protrusion 1211a.

When the interior body 12 having the hammock 121 as described above is attached to the cap body 11, the ridges 111 of the cap body 11 come into contact with the panel 1214, and the ear straps 13 are pushed by the cap body 11. Become. Therefore, as a result of the pressure from the cap body 11 being transmitted to a wide range of the ear straps 13 via the ridges 111 and the panel 1214, the ear straps 13 are prevented from coming off from the hammock 121 while suppressing damage to the ear straps 13 due to the pressure. can.

(Modification 2 of the first aspect)
FIG. 5 shows another example of a hammock 121 having projections. FIG. 5 shows the branch portions 121b extending from each of the three or more suspension bands forming the hammock 121 together with the ear straps 13. As shown in FIG. The ear strap 13 in this example is doubled by folding back the tip, and a hole 131 is formed in the doubled portion. In other words, the ear strap 13 is reinforced by forming a double structure in the vicinity of the hole 131 by folding.

However, the folding is not essential, and for example, by adding scraps of the same material as the ear straps 13, the vicinity of the holes 131 of the ear straps 13 becomes a double structure and is reinforced. Alternatively, the vicinity of the hole 131 of the ear strap 13 may be reinforced by, for example, resin coating or attachment of a reinforcing material such as tape, and the reinforcing structure is not critical.

This reinforcing structure can also be used for the ear straps 13 in other modifications of the first aspect and the ear straps 13 in the second aspect described later.

The hammock 121 in this example has protrusions 1211b formed on the branches 121b of each of three or more hanging bands. The branch portion 121b branches from the suspension band, extends obliquely downward, and then bends downward. That is, the vicinity of the tip of the branch portion 121b faces downward, and the projection 1211b includes a leg extending horizontally from the portion directed downward in the vicinity of the tip of the branch 121b, and a leg provided vertically at the tip of the leg. and an elongated member. The longitudinal member has a width substantially equal to the hole 131 of the ear strap 13 , but has a larger longitudinal width, so that it can pass through the hole 131 of the ear strap 13 .

When the assembling operator passes the longitudinal member of the projection 1211b through the hole 131 of the ear cord 13, the ear cord 13 is coupled with the projection 1211b of the branch portion 121b.

When the interior body 12 having the hammock 121 as described above is attached to the cap body 11, the projection 111 of the cap body 11 abuts against the longitudinal member of the protrusion 1211b, and the ear straps 13 are pushed by the cap body 11. result in Therefore, the pressure from the cap body 11 is transmitted to the ear straps 13 via the elongated members of the projections 111 and the protrusions 1211b, so that the ear straps 13 can be prevented from coming off the hammock 121.

(Modification 3 of the first aspect)
FIG. 6 is a diagram showing still another example of the hammock 121 having projections. FIG. 6 shows the ends of each of the three or more hanging bands forming the hammock 121 together with the ear straps 13 . The ear straps 13 in this example have holes 131 near the ends. The hole 131 is, for example, rectangular, but may be circular or the like, and its shape does not matter.

The hammock 121 in this example includes a plate extending upward along the outer surface of each of the three or more suspension bands at the end of each of the three or more suspension bands on the side of the headband 122 (hereinafter sometimes simply referred to as "end"). shaped protrusion 1211c is formed.

However, the position of the plate-like protrusion 1211c is not limited to the end portion, and may be, for example, the center of the hanging band or anywhere on the hammock 121. FIG. The plate-shaped projection 1211c may extend upward along the outer surface of the hammock 121. As shown in FIG.

A rectangular hole 1212c is formed in the end portion, and the plate-like protrusion 1211c has a thin columnar leg provided immediately below the rectangular hole 1212c and a thin columnar leg provided directly below the rectangular hole 1212c. It is composed of a vertically long plate member provided. This plate member has a length in the vertical direction that is longer than the length in the vertical direction of the rectangular hole 1212c, and a width that is narrower than the horizontal width of the rectangular hole 1212c. Therefore, the tip of the plate-like projection 1211c can penetrate the rectangular hole 1212c and protrude toward the inner surface of the hammock 121. As shown in FIG.

As shown in FIG. 6, the plate member preferably has a tapered shape in which the lateral width becomes narrower toward the top, but the plate member does not necessarily have to be tapered.

Further, the width of the plate member forming the protrusion 1211c is the same as or narrower than the width of the hole 131 of the ear strap 13. As shown in FIG. Furthermore, the shape and size of the legs that constitute the projection 1211c are the same as or substantially the same as the shape and size of the hole 131 of the ear strap 13 . Therefore, the hole 131 of the ear string 13 passes through the plate member of the projection 1211c and engages with the leg portion of the projection 1211c.

The assembling operator first passes the hole 131 of the ear string 13 through the tip of the plate-like protrusion 1211c, and engages the hole 131 of the ear string 13 with the leg portion of the plate-like protrusion 1211c. Next, the assembling worker pushes the tip of the plate-shaped protrusion 1211c into the rectangular hole 1212c of the hammock 121. As shown in FIG.

Thereby, the hammock 121 and the ear straps 13 are connected, and the ear straps 13 are difficult to fall off from the hammock 121 before the hammock 121 is connected to the cap body 11.例文帳に追加As a result, assembly of the helmet 1 is facilitated.

Next, the assembling worker joins the headband 122 to the hammock 121 to which the ear straps 13 are thus joined to form the inner body 12 , and attaches the inner body 12 to the hat body 11 . As a result, the protrusion 111 of the cap body 11 abuts against the plate member of the protrusion 1211 c , and the ear straps 13 are pushed by the cap body 11 . Therefore, after the hammock 121 is connected to the cap body 11, pressure from the cap body 11 is transmitted to the ear straps 13 via the ridges 111 and the plate-like protrusions 1211c, and as a result, the ear straps 13 come off from the hammock 121. can be prevented.

(Second aspect)
FIG. 7 is a diagram showing an example of a cap body 11 having projections. FIG. 7 shows the lower end of the inner surface of the cap body 11 together with the ear straps 13 and the ends of the hammock 121 .

A hole 131 is formed in the vicinity of the end of the ear string 13 in this example. However, the positions of the holes 131 in the ear straps 13 are not limited. Further, the hole 131 is, for example, elliptical, but may be circular or the like, and the shape is not limited.

The hammock 121 in this example has a second hole 1214d at the end. However, the position of the second hole 1214d in the hammock 121 does not matter. Also, the second hole 1214d is, for example, rectangular, but may be circular or the like, and its shape does not matter.

The cap body 11 has a protrusion 1211d formed at the lower end of the inner surface thereof. However, the protrusion 1211d may be formed anywhere on the inner surface of the cap body 11 . The protrusion 1211d is composed of an elongated columnar leg and a rectangular plate member provided perpendicular to the tip of the leg. This plate member has a vertical length shorter than the vertical length of the second hole 1214d and a width narrower than the horizontal width of the second hole 1214d.

Also, the longitudinal length and width of the plate member are generally the same or substantially the same as the major and minor diameters of the hole 131 of the ear strap 13 . However, the plate member may be of any size as long as it can pass through the hole 131 of the ear strap 13 .

Therefore, the tip of the projection 1211d of the cap body 11 can pass through the hole 131 of the ear strap 13 and also through the second hole 1214d of the hammock 121 to protrude toward the inside of the hammock 121.

A connecting portion for connecting the cap body 11 to the hammock 121 is also provided at the lower end portion of the inner surface of the cap body 11 .

A groove 12111 that engages with the protrusion 111 is formed at the tip of the columnar projection 1211, and the engagement between the protrusion 111 and the groove 12111 effectively prevents the ear cord 13 from falling off. can be prevented. Also, the connection between the hammock 121 and the hat body 11 is strengthened.

In addition, in the first aspect, the columnar projections 1211 are inclined upward with respect to the normal line of the outer surface of the hammock 121, so that the ear straps 13 are pulled out before the hammock 121 is connected to the hat body 11. Since falling off can be prevented, assembly of the helmet 1 is facilitated.

In addition, in the first aspect, the hammock 121 is further formed with a horizontal hole 1212 through which the tip of the ear string 13 can pass while the projection 1211 of the hammock 121 passes through the hole 131 of the ear string 13 . Therefore, by inserting the tip of the ear strap 13 into the horizontal hole 1212 and then bending the ear strap 13 downward, the protrusion 1211 of the hammock 121 can be easily passed through the hole 131 of the ear strap 13, and the helmet 1 can be assembled. becomes easier.

In addition, in Modified Example 1 of the first aspect, the hammock 121 is provided with a panel 1214 that can be opened and closed via a hinge 1213 at a position corresponding to the projection 1211a of the hammock 121. The panel 1214 includes: A second hole 1214a through which the projection 1211a of the hammock 121 penetrates is formed. The slit 1213a is penetrated, and the protrusion 1211a of the hammock 121 is closed after passing through the hole 131 of the ear string 13. As shown in FIG. Therefore, by closing the panel 1214 before connecting the hammock 121 to the cap body 11, the ear straps 13 can be prevented from coming off, so that the helmet 1 can be easily assembled. In addition, after the hammock 121 is connected to the cap body 11, pressure from the cap body 11 is widely transmitted to the ear straps 13 through the panel 1214, thereby preventing the ear straps 13 from coming off while suppressing damage to the ear straps 13. can.

In addition, in Modified Example 2 of the first aspect, since the ear straps 13 are reinforced in the vicinity of the holes 131, it is possible to compensate for the decrease in the strength of the ear straps 13 due to the opening of the holes 131 in the ear straps 13. can.
