Description

Masks for water activities

The invention relates to a mask for water activities, in particular to a mask for water activities (including above-water and underwater activities) such as swimming, snorkeling, free diving, and fishing, and the mask usually at least covers the user's eyes.

The common masks used for underwater activities at present include swimming goggles that only cover the eyes or diving masks that cover both the eyes and the nose. Later, full-face breathable masks that cover the eyes, nose and mouth were also developed. Among these styles, diving masks and full-face respirable masks are designed to avoid touching the user's face (especially the area where the bridge of the nose and the root of the nose are located) as much as possible to avoid discomfort to the user, and may require a large enough viewing lens to maintain a sufficient field of view, and may even require a breathing channel to be configured in the mask body (especially in the design of full-face respirable masks). These requirements are not conducive to the miniaturization of the mask design, and also make the heaviest area of the mask (i.e. the area where the frame and lens are located) far away from the user's face, so that in terms of structure, this area will generate downward tension, which will affect the watertight effect of the waterproof sealing skirt. In order to improve the stability of the mask when worn, most designs choose to increase the wall thickness of the waterproof sealing skirt to keep the weight distribution of the mask body balanced.

However, increasing the thickness of the waterproof sealing skirt is not conducive to flexible deformation. If it is necessary to adapt to the different face shapes of users due to age, gender, and race to ensure comfortable wearing and excellent waterproofness, it will be even more difficult. Therefore, after the industry usually develops a mask style, it is inevitable that it must produce products of multiple sizes corresponding to the same style for selection, which will inevitably cause a significant increase in the production and sales costs of the mask.

Furthermore, once a general user puts on the mask, the waterproof sealing skirt is attached to the user's face like a suction cup, lacking sufficient cushioning ability. When performing underwater sports, if there is an external force impact or the user's own face shakes, the waterproof sealing skirt will be slightly separated from the face and water will enter, which is also one of the shortcomings of current masks.

In view of this, designing a mask for water activities that can partially or fully solve the above problems has become a goal that the industry strives to achieve.

One purpose of the present invention is to provide a mask for water activities, as long as the mask has a waterproof sealing skirt that fits the face, a long groove with substantial size significance (not decorative) can be provided in the area of the waterproof sealing skirt that does not fit the face, especially the outer edge of a hard frame or a soft frame formed integrally with the waterproof sealing skirt. By having the characteristic of being easier to bend along the longitudinal direction of the groove, the flexible deformation ability of the waterproof sealing skirt can be improved, that is, the waterproof sealing skirt can be made easier to stretch or bend within a certain range, so as to better adapt to the contours of the faces of different users. At the same time, in a specific implementation, the elongated groove can have the same effect as a rib, which can undoubtedly enhance the strength of the waterproof sealing skirt. On the one hand, it reduces the need to thicken the waterproof skirt, and on the other hand, it increases the strength of the mask body when worn. When the mask is accidentally hit by external force or the user's face shakes unexpectedly, it can provide further cushioning, so that the waterproof sealing skirt will not immediately fall off the face, and can still maintain good water tightness.

To achieve the above-mentioned purpose, the present invention discloses a mask for underwater activities, comprising a lens portion, a lens frame portion and a waterproof sealing skirt. The waterproof sealing skirt has a first area and a second area. A portion of the first area and the lens portion are waterproofly embedded in the lens frame portion. When a user wears the mask for underwater activities, a rear edge of the second area can fit the face of the user. At least one groove is formed between the first area and the second area of the waterproof sealing skirt to substantially increase the degree of elastic deformation of the waterproof sealing skirt so that the rear edge can better fit the contour of the face of the user. The at least one groove has at least two of a width, a depth and an external angle, wherein the width is between 1.5 and 25 millimeters (mm), the depth is between 2 and 30 millimeters (mm), and the external angle is between 5 and 180 degrees.

In one implementation, the first area of the waterproof sealing skirt has an upper frame portion and a lower cover portion, and the lens frame portion is formed by extending the upper frame portion as an integral part, so that the lens portion is waterproofly embedded in the lens frame portion, so that when the user wears the mask for water activities, the lens portion can properly cover the user's eyes and the lower cover portion can properly cover the user's nose.

In one example, the waterproof sealing skirt is formed with a plurality of grooves circumferentially located on an outer edge of the lens frame portion.

In one example, the width of each of the grooves is between 2 and 10 mm, the depth is between 5 and 15 mm, and the external angle is between 5 and 100 degrees.

In another implementation, the first area of the waterproof sealing skirt has an upper frame portion and a lower cover portion, and the upper frame portion and the lens portion are waterproofly embedded in the lens frame portion, so that when the user wears the mask for water activities, the lens portion can properly cover the user's eyes and the lower cover portion can properly cover the user's nose.

In one example, the waterproof sealing skirt is formed with a groove located on an upper side of the waterproof sealing skirt.

In one example, the width of the groove is between 5 and 20 mm, the depth is between 3 and 15 mm, and the external angle is between 5 and 100 degrees.

In yet another implementation, the first area of the waterproof sealing skirt has an upper frame portion and a lower cover portion, and the upper frame portion and the lens portion are waterproofly embedded in the lens frame portion, so that when the user wears the mask for water activities, the lens portion can properly cover the user's eyes, and the lower cover portion can properly cover the user's nose and mouth.

In one example, the waterproof sealing skirt is formed with two grooves, which are respectively located at two opposite sides of the waterproof sealing skirt.

In one example, the width of each of the grooves is between 3 and 10 mm, the depth is between 5 and 20 mm, and the external angle is between 15 and 120 degrees.

In yet another embodiment, the first area of the waterproof sealing skirt and the lens portion are waterproofly embedded in the lens frame portion, so that when the user wears the mask for water activities, the lens portion can properly cover the user's eyes, nose and mouth.

In one example, the waterproof sealing skirt is formed with a groove located at a lower side of the waterproof sealing skirt.

In one example, the width of the groove is between 2 and 10 mm, the depth is between 10 and 25 mm, and the external angle is between 30 and 180 degrees.

The following description of the embodiments is only for explaining the content of the present invention, and is not intended to limit the present invention. Elements not directly related to the present invention are not shown (for example, the headband that fixes the mask to the user's head is not shown in some figures), and the size relationship between the elements in the figures is only for easy understanding, and is not intended to limit the actual proportion. In addition, the front, back, left, right, inside, outside, front, back, etc. in each description are defined based on the direction of the user, which is only a relative relationship and is not intended to be limiting.

The present invention relates to a mask for water activities, which may be (but not limited to) swimming goggles, swimming masks, diving masks or any form of breathable masks (e.g., full-face masks), and all of them may adopt the structure of the mask of the present invention, and the difference lies in whether the body only covers the user's eyes, eyes and nose, or eyes, nose and mouth, and whether there is a breathing tube connected to the inside of the body, etc. However, such changes do not affect the characteristic description of the mask body of the present invention, and therefore, parts other than the mask body, such as the breathing tube, headband, air intake and exhaust channels, etc., which are not related to the structure of the body, are no longer specifically described. In addition, in order to facilitate the description of the characteristics of the present invention, the headband is only retained in Figures 2A, 3A, and 4A, and the remaining figures are omitted.

The first embodiment of the present invention is a mask 1 for underwater activities, as shown in FIGS. 1A and 1B. The mask 1 for underwater activities is a mask used for activities such as fishing, swimming training or snorkeling. The mask 1 for underwater activities comprises a lens portion 11, a lens frame portion 13 and a waterproof sealing skirt 15. The waterproof sealing skirt 15 has a first area (i.e., front area) 15a and a second area (i.e., rear area) 15b. A portion of the first area 15a is waterproofly embedded in the lens frame portion 13 together with the lens portion 11.

In this embodiment, the first area 15a of the waterproof sealing skirt 15 has an upper frame portion 15a1 and a lower cover portion 15a2. The lens frame portion 13 is formed by integrally extending the upper frame portion 15a1, so that the lens portion 11 can be waterproofly embedded in the upper frame portion 15a1. When a user wears the underwater activity mask 1 through a fastening device (for example, an elastic headband, not shown), the lens portion 11 can cover the user's eyes, and the lower cover portion 15a2 can cover the user's nose. As shown in Figure 1A, the lens portion 11 and the lens frame portion 13 respectively include two separate lenses 11a, 11b and two separate frames 13a, 13b.

In addition, when the user wears the mask 1 for underwater activities, a rear edge 15b1 of the second area 15b of the waterproof sealing skirt 15 can fit the user's face. A plurality of grooves 15g are formed between the first area 15a and the second area 15b of the waterproof sealing skirt 15, which are circumferentially located at an outer edge of the lens frame 13 (i.e., corresponding to the position of the outer periphery of the eye sockets and the brow bone of the user). In this embodiment, as shown in Figures 1A and 1B, the grooves 15g are substantially horizontal, that is, extending along the periphery of the lens frame 13. The grooves 15g can be designed to have a certain depth to produce an effect equivalent to a rib. When the waterproof sealing skirt 15 is pushed by an external force, it can resist a part of the position of the outer periphery of the eye sockets and the brow bone of the user, so that the mask 1 for underwater activities can fit the face very stably. However, in other embodiments, the groove may not extend completely along the periphery of the lens frame, that is, it is not limited to the manner shown in Figures 1A and 1B.

Specifically, further referring to FIG. 1C , a partial cross-sectional view of the waterproof sealing skirt 15 near the groove 15g is shown. Each groove 15g has at least two of a width w, a depth d, and an outer angle θ, wherein the width w is between 1.5 and 25 millimeters (mm), the depth d is between 2 and 30 mm, and the outer angle θ is between 5 and 180 degrees. Preferably, the width w of each groove 15g is between 2 and 10 mm, the depth d is between 5 and 15 mm, and the outer angle θ is between 5 and 100 degrees. Under these substantial dimensional settings, the grooves 15g can substantially increase the degree of elastic deformation of the waterproof sealing skirt 15 so that the rear edge 15b1 fits the contour of the user's face better. Furthermore, the groove 15g not only improves the wearing flexibility of the mask 1 for water sports for more different face shapes, but also provides further buffering when the user is accidentally affected by internal and/or external forces. As shown in FIG. 1D , it depicts a deformation state of the groove 15g when the user wears the mask 1 and his face fits against the waterproof sealing skirt and squeezes the waterproof sealing skirt 15 forward (as shown by the arrow).

The second embodiment of the present invention is a mask 2 for underwater activities, as shown in Figures 2A and 2B. The mask 2 for underwater activities is a mask used for activities such as snorkeling or diving. The mask 2 for underwater activities includes a lens portion 21, a lens frame portion 23 and a waterproof sealing skirt 25. The waterproof sealing skirt 25 has a first area 25a and a second area 25b. A portion of the first area 25a is waterproofly embedded in the lens frame portion 23 together with the lens portion 21.

In this embodiment, the first area 25a of the waterproof sealing skirt 25 has an upper frame portion 25a1 and a lower cover portion 25a2. The upper frame portion 25a1 and the lens portion 21 are waterproofly embedded in the lens frame portion 23. When a user wears the underwater activity mask 2 through a fastening device (for example, an elastic headband 201, as shown in FIG. 2A), the lens portion 21 can appropriately cover the user's eyes, and the lower cover portion 25a2 can appropriately cover the user's nose. As shown in FIG. 2A, the lens frame portion 23 is a single component, and the lens portion 21 includes two separate lenses 21a and 21b. The lens portion 21, the lens frame portion 23 and the waterproof sealing skirt 25 are assembled to form the underwater activity mask 2.

In addition, when the user wears the mask 2 for water activities, a rear edge 25b1 of the second area 25b of the waterproof sealing skirt 25 can fit the user's face. A groove 25g is formed between the first area 25a and the second area 25b of the waterproof sealing skirt 25, and is located on an upper side of the waterproof sealing skirt 25 (i.e., close to the user's brow bone). Similarly, further reference is made to FIG. 2C, which shows a partial cross-sectional view of the waterproof sealing skirt 25 near the groove 25g. The groove 25g has at least two of a width w, a depth d, and an external angle θ, wherein the width w is between 1.5 and 25 mm, the depth d is between 2 and 30 mm, and the external angle θ is between 5 and 180 degrees. Preferably, the width w of the groove 25g is between 5 and 20 mm, the depth d is between 3 and 15 mm, and the outer angle θ is between 5 and 100 degrees. When the waterproof sealing skirt 25 is affected by internal and/or external forces, the groove 25g will be deformed. As shown in FIG. 2D , it depicts a deformed state of the groove 25g when the user wears the mask 2 and his face fits the waterproof sealing skirt and squeezes the waterproof sealing skirt 25 forward (as shown by the arrow).

The third embodiment of the present invention is a mask 3 for underwater activities, as shown in FIGS. 3A and 3B. The mask 3 for underwater activities is a full-face mask in the form of glasses for activities such as snorkeling. The mask 3 for underwater activities includes a lens portion 31, a lens frame portion 33, a waterproof sealing skirt 35, and a breathing tube 37. The waterproof sealing skirt 35 has a first area 35a and a second area 35b. A portion of the first area 35a is waterproofly embedded in the lens frame portion 33 together with the lens portion 31.

In this embodiment, the first area 35a of the waterproof sealing skirt 35 has an upper frame portion 35a1 and a lower cover portion 35a2. The upper frame portion 35a1 and the lens portion 31 are waterproofly embedded in the lens frame portion 33. When a user wears the underwater activity mask 3 through a fastening device (for example, an elastic headband 301, as shown in FIG. 3A ), the lens portion 31 can properly cover the user's eyes, and the lower cover portion 35a2 can properly cover the user's nose and mouth. As shown in FIG. 3A , the lens portion 31 and the lens frame portion 33 are both a single component. The lens portion 31, the lens frame portion 33, the waterproof sealing skirt 35 and the breathing tube 37 are assembled to form the underwater activity mask 3.

In addition, when the user wears the underwater mask 3, a rear edge 35b1 of the second area 35b of the waterproof sealing skirt 35 can fit the user's face. Two grooves 35g are formed between the first area 35a and the second area 35b of the waterproof sealing skirt 35, respectively located at two opposite sides of the waterproof sealing skirt 35 (i.e., positions close to the outer sides of the user's eyes). Optionally, a groove 35g can also be added to a bottom of the waterproof sealing skirt 35 to increase the flexibility of the underwater mask 3 in fitting the user's chin.

Similarly, further referring to FIG. 3C , a partial cross-sectional view of the waterproof sealing skirt 35 near the groove 35g is shown. The groove 35g has at least two of a width w, a depth d, and an external angle θ, wherein the width w is between 1.5 and 25 mm, the depth d is between 2 and 30 mm, and the external angle θ is between 5 and 180 degrees. Preferably, the width w of each groove 35g is between 3 and 10 mm, the depth d is between 5 and 20 mm, and the external angle θ is between 15 and 120 degrees. When the waterproof sealing skirt 35 is affected by internal force and/or external force, the groove 35g will be deformed. As shown in FIG. 3D , it depicts a deformation state of the groove 35g when the user wears the mask 3 and his face fits against the waterproof sealing skirt and squeezes the waterproof sealing skirt 35 forward (as shown by the arrow).

The fourth embodiment of the present invention is a mask 4 for underwater activities, as shown in FIGS. 4A and 4B. The mask 4 for underwater activities is a full-face mask for activities such as snorkeling. The mask 4 for underwater activities includes a lens portion 41, a lens frame portion 43, a waterproof sealing skirt 45 and a breathing tube 47. The waterproof sealing skirt 45 has a first area 45a and a second area 45b. A portion of the first area 45a is waterproofly embedded in the lens frame portion 43 together with the lens portion 41.

In this embodiment, when a user wears the underwater mask 4 through a fastening device (e.g., an elastic headband 401, as shown in FIG. 4A ), the lens portion 41 can properly cover the user's eyes, nose, and mouth. As shown in FIG. 4A , the lens portion 41 and the lens frame portion 43 are both a single component. The lens portion 41, the lens frame portion 43, the waterproof sealing skirt 45, and the breathing tube 47 are assembled to form the underwater mask 4.

In addition, when the user wears the mask 4 for water activities, a rear edge 45b1 of the second area 45b of the waterproof sealing skirt 45 can fit the user's face. A groove 45g is formed between the first area 45a and the second area 45b of the waterproof sealing skirt 45, and is located at a lower side of the waterproof sealing skirt 45 (i.e., close to the user's chin).

Similarly, further referring to FIG. 4C , a partial cross-sectional view of the waterproof sealing skirt 45 near the groove 45g is shown. The groove 45g has at least two of a width w, a depth d, and an external angle θ, wherein the width w is between 1.5 and 25 mm, the depth d is between 2 and 30 mm, and the external angle θ is between 5 and 180 degrees. Preferably, the width w of the groove 45g is between 2 and 10 mm, the depth d is between 10 and 25 mm, and the external angle θ is between 30 and 180 degrees. When the waterproof sealing skirt 45 is affected by internal and/or external forces, the groove 45g will be deformed. As shown in FIG. 4D , it depicts a deformation state of the groove 45g when the user wears the mask 4 and his face fits against the waterproof sealing skirt and squeezes the waterproof sealing skirt 45 forward (as shown by the arrow).

In general, referring to the above figures, the new mask for underwater activities includes a lens portion, a lens frame portion and a waterproof sealing skirt. The waterproof sealing skirt has a front area (i.e., the first area) and a rear area (i.e., the second area). The lens portion and the lens frame portion are defined as a superordinate concept, which may refer to an embodiment including two lenses and two lens frames to cover the left and right eyes respectively (as shown in FIG. 1A of the first embodiment), or an embodiment combining two lenses with a lens frame (as shown in FIG. 2A of the second embodiment); it may also be an embodiment including one lens and one lens frame to cover the left and right eyes at the same time (as shown in FIG. 3A of the third embodiment), and it may be an embodiment of a full-lens mask that covers the eyes, nose, and mouth at the same time (as shown in FIG. 4A and 4B of the fourth embodiment). As shown in the first to fourth embodiments, the recessed direction of the grooves 15g, 25g, 35g, and 45g may be inwardly directed toward the user; however, in other embodiments, the recessed direction may also be outwardly directed away from the user, thereby forming a convex appearance.

Further referring to FIG. 5 , the groove shape of the present invention can be varied in many ways, for example, the cross-sectional views shown in (a) to (f) can be U-shaped or V-shaped with corners, or U-shaped without corners or other possible variations. The width w is the maximum width of the groove opening, and the depth d is the measurement measured from the center of the groove bottom to the imaginary surface across the groove opening. The outer angle θ is the angle between the outer side wall of the groove and the face section of the waterproof sealing skirt (i.e., corresponding to the second area defined above).

The above embodiment is to provide a long groove on the waterproof sealing skirt that is not in contact with the user's face, which is sufficient for the waterproof sealing skirt to bend and deform more easily, so as to make the waterproof sealing skirt more flexible and deformable than before under the same design parameters of the frame and lens, so as to meet the needs of users with different face shapes, and it is not necessary to manufacture masks of different sizes for different users, and at the same time, it can achieve better cushioning and support effects. Therefore, the layout direction of the groove is best to extend along the periphery of the mask body with its longitudinal length. As for the form and number of the grooves, and how to arrange them, etc., it is not a question.

In addition, the above-mentioned embodiments are only exemplary. In FIG. 5 , various possible groove shape changes and the measurement criteria of the width w, depth d and outer angle θ are shown. A person with ordinary knowledge in the relevant technical field can understand the various possible changes in the groove shape of the present invention, and any changes are intended to be protected by the present invention. For example, unlike the underwater activity mask 2 of FIG. 2B showing a U-shaped groove, FIGS. 6A and 6B respectively show underwater activity masks 6a and 6b having two types of V-shaped grooves 65g. In Fig. 6A, the outer angle θ of the groove 65g of the underwater mask 6a is close to a substantially flat state of 180 degrees, so it is not marked; while in Fig. 6B, the outer angle θ of the groove 65g of the underwater mask 6b is close to 90 degrees. In both Figs. 6A and 6B, the waterproof sealing skirt 25 presents a cross-section similar to an S shape.

In summary, the novel mask for water activities improves the flexibility and deformation ability of the waterproof sealing skirt by providing a deformable groove at the part of the waterproof sealing skirt that does not contact the user's face, so that it can be improved to adapt to the different face shapes of users of different ages, genders, and races to ensure comfortable wearing and excellent waterproofness.

The above-mentioned embodiments are only used to illustrate the implementation mode of the present invention and to explain the technical features of the present invention, and are not used to limit the scope of protection of the present invention. Any changes or arrangements of equalities that can be easily completed by those familiar with this technology are within the scope of the present invention, and the scope of protection of the present invention shall be subject to the scope of the patent application.
