The waterproof sealing skirt is provided with a first area, a second area and at least one groove formed between the first area and the second area. The groove has at least two of a width, a depth and an outer included angle in a specific numerical range, so that the flexible deformation degree of the waterproof sealing skirt is substantially increased, and when a user wears the underwater activity mask, a rear edge of the second area can better fit the outline of the face of the user.

Description

Technical Field

[0001] The utility model relates to a mask for underwater activities, in particular to a mask for swimming, snorkeling, free diving, fishing and other underwater activities (including above-water and underwater activities), and the mask usually at least covers the eyes of the user. Background Art

[0002] The common masks 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 respirable masks that cover the eyes, nose and mouth were 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) as much as possible to avoid discomfort to the user, and may require a large enough viewing lens to maintain a sufficient field of vision, 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 lenses are located) far away from the user's face, so that in terms of structure, this area will generate downward pulling force, 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 maintain a balanced weight distribution of the mask body.

[0003] However, increasing the thickness of the waterproof sealing skirt is not conducive to flexible deformation, and it is even more difficult to adapt to the different face shapes of users due to age, gender, and race to ensure comfortable wearing and excellent waterproofness. 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.

[0004] Furthermore, once a user puts on the mask, the waterproof sealing skirt is attached to the user's face like a suction cup, lacking sufficient cushioning capacity. 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 defects of existing masks.

[0005] 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 pursue. Utility Model Content

[0006] An object of the present invention is to provide a face mask for underwater activities. As long as the face mask has a waterproof sealing skirt that fits the face, a long groove with a substantial dimensional significance (rather than decorative) can be provided in the non-face-fitting area of the waterproof sealing skirt, especially at the outer edge of a rigid frame or a soft frame integrally formed with the waterproof sealing skirt. By virtue of the characteristic of being more easily bent 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 more easily stretched or bent within a certain range to better adapt to the facial contours of different users. At the same time, in a specific implementation, the long groove can have the effect equivalent to that of a rib, which not only reduces the need to thicken the waterproof skirt part, but also increases the strength of the face mask body during wearing. When the face mask is accidentally impacted by an external force or the user's face shakes unexpectedly, it can provide further buffering so that the waterproof sealing skirt will not immediately separate from the face and can still maintain good water tightness.

[0007] To achieve the above object, the present invention discloses a face mask for underwater activities, which includes a lens part, a frame part and a waterproof sealing skirt. The waterproof sealing skirt has a first area and a second area. A part of the first area and the lens part are jointly waterproofly embedded in the frame part. When a user wears the face mask for underwater activities, a trailing edge of the second area is adapted to fit the user's face. At least one groove is formed between the first area and the second area of the waterproof sealing skirt, thereby substantially increasing a degree of flexible deformation of the waterproof sealing skirt so that the trailing edge fits better to a contour of the user's face. The at least one groove has at least two of a width, a depth and an outer included angle, wherein the width is between 1.5 and 25 millimeters (mm), the depth is between 2 and 30 millimeters (mm), and the outer included angle is between 5 and 180 degrees.

[0008] In one implementation, the first area of the waterproof sealing skirt has an upper frame part and a lower cover part, and the frame part is integrally extended from the upper frame part so that the lens part is waterproofly embedded in the frame part. Thus, when the user wears the face mask for underwater activities, the lens part is adapted to cover the user's eyes, and the lower cover part is adapted to cover the user's nose.

[0009] In an example, a plurality of grooves are formed in the waterproof sealing skirt and are circumferentially located at an outer edge of the frame part.

[0010] In an example, the width of each of the plurality of grooves is between 2 and 10 mm, the depth is between 5 and 15 mm, and the outer included angle is between 5 and 100 degrees.

[0011] In another implementation, the first region 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 jointly and waterproofly inlaid in the frame portion. Thus, when the user wears the mask for underwater activities, the lens portion can suitably shield the user's eyes, and the lower cover portion can suitably shield the user's nose.

[0012] In an example, a groove is formed in the waterproof sealing skirt on an upper side thereof.

[0013] In an example, the width of the groove is between 5 and 20 mm, the depth is between 3 and 15 mm, and the outer included angle is between 5 and 100 degrees.

[0014] In yet another implementation, the first region 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 jointly and waterproofly inlaid in the frame portion. Thus, when the user wears the mask for underwater activities, the lens portion can suitably shield the user's eyes, and the lower cover portion can suitably shield the user's nose and mouth.

[0015] In an example, two grooves are formed in the waterproof sealing skirt on two opposite sides thereof respectively.

[0016] In an example, the width of each of the two grooves is between 3 and 10 mm, the depth is between 5 and 20 mm, and the outer included angle is between 15 and 120 degrees.

[0017] In still another implementation, the first region of the waterproof sealing skirt and the lens portion are jointly and waterproofly inlaid in the frame portion. Thus, when the user wears the mask for underwater activities, the lens portion can suitably shield the user's eyes, nose and mouth.

[0018] In an example, a groove is formed in the waterproof sealing skirt on a lower side thereof.

[0019] In an example, the width of the groove is between 2 and 10 mm, the depth is between 10 and 25 mm, and the outer included angle is between 30 and 180 degrees.

[0020] The beneficial effect of the present utility model is that the mask for underwater activities of the present utility model improves the flexible deformation ability of the waterproof sealing skirt by providing deformable grooves at the parts where the waterproof sealing skirt does not contact the user's face. Therefore, it can improve the adaptation to different user face shapes of different ages, genders and races to ensure comfortable wearing and excellent waterproof performance.

[0057] The following description of the embodiments is only for explaining the content of the present invention and not for limiting the present invention. Elements not directly related to the present invention are not shown (for example, the headband for fixing the face mask to the user's head is not shown in some of the drawings), and the dimensional relationships between the elements in the drawings are only for easy understanding and not for limiting the actual ratio. In addition, the front, rear, left, right, inside, outside, front, and rear in each description are defined based on the direction of the user and are only relative relationships and not for limitation.

[0058] The present invention relates to a face mask for underwater activities, which can be (but is not limited to) swimming goggles, a swimming face mask, a diving mask, or any form of breathable face mask (for example, a full-face mask). The structure of the face mask of the present invention can be adopted, and the difference lies only in that the body only covers the user's eyes, both the eyes and the nose, or the eyes, nose, and mouth, and whether there is a breathing tube communicating with the inside of the body. However, these variations do not affect the description of the features of the present invention on the face mask body. Therefore, parts outside the face mask body, such as the breathing tube, headband, air intake and exhaust channels, etc., which are not related to the body structure, will not be described in detail. In addition, for the convenience of explaining the features of the present invention, the headband is only retained in Figure 2A , Figure 3A , Figure 4A , and the rest of the figures are omitted.

[0059] The first embodiment of the present invention relates to an underwater activity face mask 1, as shown in Figure 1A and Figure 1B . The underwater activity face mask 1 is a face mask for activities such as spear fishing, swimming training, or snorkeling. The underwater activity face mask 1 includes a lens part 11, a frame part 13, and a waterproof sealing skirt 15. The waterproof sealing skirt 15 has a first area (i.e., the front area) 15a and a second area (i.e., the rear area) 15b. A part of the first area 15a and the lens part 11 are jointly waterproof and inlaid in the frame part 13.

[0060] In this embodiment, the first region 15a of the waterproof sealing skirt 15 has an upper frame portion 15a1 and a lower cover portion 15a2. The frame portion 13 is integrally extended from 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 (such as an elastic headband, not shown in the figure), the lens portion 11 can shield the user's eyes, and the lower cover portion 15a2 can shield the user's nose. As Figure 1A shown, the lens portion 11 and the frame portion 13 respectively include two separate lenses 11a, 11b and two separate frames 13a, 13b.

[0061] In addition, when the user wears the underwater activity mask 1, a trailing edge 15b1 of the second region 15b of the waterproof sealing skirt 15 can fit the user's face. Between the first region 15a and the second region 15b of the waterproof sealing skirt 15, a plurality of grooves 15g are formed, which are circumferentially located at an outer edge of the frame portion 13 (i.e., the position corresponding to the periphery of the user's eye socket and the eyebrow bone). In this embodiment, as Figure 1A and Figure 1B shown, the grooves 15g are substantially horizontal, that is, extending along the circumference of the frame portion 13. The grooves 15g can be designed to have a certain depth to produce an effect equivalent to ribs. When the waterproof sealing skirt 15 is pushed by an external force, it can resist a part of the position of the periphery of the user's eye socket and the eyebrow bone, so that the underwater activity mask 1 can fit the face stably. However, in other embodiments, the grooves may not completely extend along the circumference of the frame portion, that is, not limited to Figure 1A and Figure 1B shown.

[0062] Specifically, further referring to Figure 1C , which shows a partial cross-sectional view of the waterproof sealing skirt 15 near the grooves 15g. Each groove 15g has at least two of a width w, a depth d, and an outer included 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 included 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 millimeters mm, and the outer included angle θ is between 5 and 100 degrees. Under these substantially meaningful dimension settings, the plurality of grooves 15g can substantially increase the degree of flexible deformation of the waterproof sealing skirt 15, so that the trailing edge 15b1 can fit the contour of the user's face better. Moreover, in addition to improving the wearing elasticity of the underwater activity mask 1 for more different face shapes, the grooves 15g also provide further buffering when the user is accidentally affected by internal and / or external forces. As Figure 1DAs shown, it depicts a deformed state of the groove 15g after the user wears the face mask 1 and presses the waterproof sealing skirt 15 forward with their face fitting against the waterproof sealing skirt (as indicated by the arrow).

[0063] The second embodiment of the present utility model relates to a face mask 2 for water activities, as Figure 2A and 2B shown. The face mask 2 for water activities is a face mask for activities such as snorkeling or diving. The face mask 2 for water activities includes a lens part 21, a frame part 23, and a waterproof sealing skirt 25. The waterproof sealing skirt 25 has a first region 25a and a second region 25b. A part of the first region 25a and the lens part 21 are jointly waterproofly inlaid in the frame part 23.

[0064] In this embodiment, the first region 25a of the waterproof sealing skirt 25 has an upper frame part 25a1 and a lower cover part 25a2. The upper frame part 25a1 and the lens part 21 are jointly waterproofly inlaid in the frame part 23. When a user wears the face mask 2 for water activities through a fastening device (for example: an elastic headband 201, as Figure 2A shown), the lens part 21 can suitably cover the user's eyes, and the lower cover part 25a2 can suitably cover the user's nose. As Figure 2A shown, the frame part 23 is a single component, and the lens part 21 includes two separate lenses 21a, 21b. The lens part 21, the frame part 23, and the waterproof sealing skirt 25 are assembled to form the face mask 2 for water activities.

[0065] In addition, when the user wears the face mask 2 for water activities, a trailing edge 25b1 of the second region 25b of the waterproof sealing skirt 25 can suitably fit against the user's face. A groove 25g is formed between the first region 25a and the second region 25b of the waterproof sealing skirt 25, located on an upper side (i.e., approaching the user's eyebrow bone position) of the waterproof sealing skirt 25. Similarly, further referring to Figure 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 outer included angle θ, where the width w is between 1.5 and 25 mm, the depth d is between 2 and 30 mm, and the outer included 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 included angle θ is between 5 and 100 degrees. When the waterproof sealing skirt 25 is affected by internal force and / or external force, the groove 25g will deform. As Figure 2D shown, it depicts a deformed state of the groove 25g after the user wears the face mask 2 and presses the waterproof sealing skirt 25 forward with their face fitting against the waterproof sealing skirt (as indicated by the arrow).

[0066] The third embodiment of the present utility model relates to a mask 3 for underwater activities, as Figure 3A and Figure 3B shown. The mask 3 for underwater activities is a goggle-type full-face mask for activities such as snorkeling. The mask 3 for underwater activities includes a lens part 31, a frame part 33, a waterproof sealing skirt 35, and a breathing tube 37. The waterproof sealing skirt 35 has a first region 35a and a second region 35b. A part of the first region 35a and the lens part 31 are jointly waterproof and inlaid in the frame part 33.

[0067] In this embodiment, the first region 35a of the waterproof sealing skirt 35 has an upper frame part 35a1 and a lower cover part 35a2. The upper frame part 35a1 and the lens part 31 are jointly waterproof and inlaid in the frame part 33. When a user wears the mask 3 for underwater activities through a fastening device (for example: an elastic headband 301, as Figure 3A shown), the lens part 31 can suitably shield the user's eyes, and the lower cover part 35a2 can suitably shield the user's nose and mouth. As Figure 3A shown, both the lens part 31 and the frame part 33 are a single component. The lens part 31, the frame part 33, the waterproof sealing skirt 35, and the breathing tube 37 are assembled to form the mask 3 for underwater activities.

[0068] In addition, when the user wears the mask 3 for underwater activities, a trailing edge 35b1 of the second region 35b of the waterproof sealing skirt 35 can suitably fit the user's face. Between the first region 35a and the second region 35b of the waterproof sealing skirt 35, two grooves 35g are formed, respectively located on two opposite sides of the waterproof sealing skirt 35 (i.e., the positions approaching the outer sides of the user's eyes). Optionally, a groove 35g can also be added to the bottom of the waterproof sealing skirt 35 to increase the flexibility of the mask 3 for underwater activities at the position where it fits the user's chin.

[0069] Similarly, further referring to Figure 3C , which shows a partial cross-sectional view of the waterproof sealing skirt 35 near the groove 35g. The groove 35g has at least two of a width w, a depth d, and an outer included angle θ, where the width w is between 1.5 and 25 mm, the depth d is between 2 and 30 mm, and the outer included 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 outer included 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 deform. As Figure 3D shown, it depicts a deformed state of the groove 35g after the user wears the mask 3 and the user's face fits the waterproof sealing skirt and presses the waterproof sealing skirt 35 forward (as shown by the arrow).

[0070] The fourth embodiment of the present utility model relates to a face mask 4 for underwater activities, as Figure 4A and 4B shown. The face mask 4 for underwater activities is a full-face mask of the full-lens type for activities such as snorkeling. The face mask 4 for underwater activities includes a lens portion 41, a frame portion 43, a waterproof sealing skirt 45, and a breathing tube 47. The waterproof sealing skirt 45 has a first region 45a and a second region 45b. A part of the first region 45a and the lens portion 41 are jointly waterproof and inlaid in the frame portion 43.

[0071] In this embodiment, when a user wears the face mask 4 for underwater activities through a fastening device (for example: an elastic headband 401, as Figure 4A shown), the lens portion 41 can suitably cover the eyes, nose, and mouth of the user. As Figure 4A shown, both the lens portion 41 and the frame portion 43 are a single component. The lens portion 41, the frame portion 43, the waterproof sealing skirt 45, and the breathing tube 47 are assembled to form the face mask 4 for underwater activities.

[0072] In addition, when the user wears the face mask 4 for underwater activities, a trailing edge 45b1 of the second region 45b of the waterproof sealing skirt 45 can suitably fit the user's face. A groove 45g is formed between the first region 45a and the second region 45b of the waterproof sealing skirt 45, and is located on the lower side of the waterproof sealing skirt 45 (i.e., approaching the user's chin position).

[0073] Similarly, further referring to Figure 4C , which shows a partial cross-sectional view of the waterproof sealing skirt 45 near the groove 45g. The groove 45g has at least two of a width w, a depth d, and an outer included angle θ, wherein the width w is between 1.5 and 25 mm, the depth d is between 2 and 30 mm, and the outer included 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 outer included angle θ is between 30 and 180 degrees. When the waterproof sealing skirt 45 is affected by internal force and / or external force, the groove 45g will deform. As Figure 4D shown, which depicts a deformed state of the groove 45g when the user wears the face mask 4 and the face fits the waterproof sealing skirt and presses the waterproof sealing skirt 45 forward (as shown by the arrow).

[0074] Generally speaking, referring to the above drawings, the face mask for underwater activities of the present utility model includes a lens portion, a frame portion, and a waterproof sealing skirt. The waterproof sealing skirt has a front region (i.e., the first region) and a rear region (i.e., the second region). The lens portion and the frame portion are definitions of the upper concept, which can refer to an embodiment including two lenses and two frames that respectively cover the left and right eyes (such as in the first embodiment of Figure 1Aas shown), or an embodiment in which a frame is combined with two lenses (such as that of the second embodiment Figure 2A as shown); it may also be an embodiment that includes one lens and one frame and simultaneously shields both the left and right eyes (such as that of the third embodiment Figure 3A as shown), and more likely an embodiment of a full-face mask that simultaneously shields the eyes, nose, and mouth (such as that of the fourth embodiment Figure 4A and Figure 4B as shown). As shown in the aforementioned first to fourth embodiments, the recessed directions of the grooves 15g, 25g, 35g, and 45g can be inwardly facing the user; however, in other embodiments, the recessed direction can also be outwardly away from the user, resulting in a convex appearance.

[0075] Further referring to Figure 5 , the groove shape of the present utility model can have various variations. For example, in the cross-sectional views shown in (a) to (f), it can be a U-shaped or V-shaped with corners, or a 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 taken between the center of the groove bottom and the imaginary surface spanning the groove opening. The outer included angle θ is the angle between the outer sidewall of the groove and the face-contacting section of the waterproof sealing skirt (i.e., corresponding to the second region defined above).

[0076] In the above embodiments, on the part of the waterproof sealing skirt of the mask body that does not contact the user's face, there is a long groove sufficient to make the waterproof sealing skirt more easily bend and deform, so as to hope that under the same design parameters of the frame part and the lens part, the flexible deformation degree of the waterproof sealing skirt can be better than the original, to conform to more users with different face shapes, without having to manufacture masks of different sizes for different users, and at the same time achieve a better buffering and supporting effect. Therefore, the layout direction of the groove is preferably along the periphery of the mask body with its longitudinal length extending. As for the form and quantity of the grooves, and how to arrange them, etc., they are not in question.

[0077] In addition, the above embodiments are only illustrative. In Figure 5 where various possible variations of the groove shape and the measurement benchmarks of its width w, depth d, and outer included angle θ have been shown, those skilled in the art can understand various possibilities of the groove shape change of the present utility model, and any change in any way is what the present utility model intends to protect. For example, different from Figure 2B the water activity mask 2 shows a U-shaped groove, Figure 6A and Figure 6B respectively show the water activity masks 6a and 6b with V-shaped grooves 65g of two types. In Figure 6A , for the water activity mask 6a, the outer included angle θ of the groove 65g approaches a substantially planar state of 180 degrees, so it is not marked; while in Figure 6BIn [the above], the external included angle θ of the groove 65g of the underwater activity mask 6b approaches 90 degrees. Figure 6A and Figure 6B In both of them, the waterproof sealing skirt 25 presents a cross-section similar to an S shape.

[0078] In summary, the underwater activity mask of the present utility model improves the flexible deformation ability of the waterproof sealing skirt by providing a deformable groove at the part where the waterproof sealing skirt does not contact the user's face. Therefore, it can adapt to the face shapes of different users of various ages, genders, and races to ensure comfortable wearing and excellent waterproof performance.

[0079] The above embodiments are only used to exemplify the implementation manners of the present utility model and to explain the technical features of the present utility model, and are not used to limit the protection scope of the present utility model. Any change or equivalent arrangement that can be easily completed by those familiar with this technology belongs to the scope claimed by the present utility model. The scope of the right protection of the present utility model shall be subject to the claims.
