MASQUE PERMEABLE A L’AIR

Abstract

The present disclosure relates to an air-permeable mask (20, 30) comprising a body (21, 31). The body comprises: a main frame (24, 34), a lens (25, 35) and a waterproof sealing skirt (26, 36), suitable for fitting on the face of a user. The body further comprises a head strap (27, 37), which has two ends (271, 272; 371, 372) fixed on the main frame or the waterproof sealing skirt. The two ends are positioned to correspond respectively to the two sides of the eyes (E) of the user. The region where the waterproof sealing skirt is configured to contact the user's face, has the highest portion (281, 381) and the lowest portion (282, 382), wherein a center point (w1) of the highest portion to a center point (w2) of the lowest portion defines a maximum height between 100 millimeters (mm) and 165 millimeters (mm).

Title of the invention: AIR-PERMEABLE MASK Technical field

[0001] The present disclosure relates to a full face mask, specifically a breathable mask for diving. Descriptions of related art

[0002] The currently marketed full face snorkeling mask (FFSM) 10 can allow the user's mouth and nose to breathe through the mask. Its structure generally comprises a body 11 and a breathing tube 12. The breathing tube 12 is in fluid communication with an interior of the body 11. The body 11 comprises a main frame 14, a lens 15 integrated into the main frame, a waterproof sealing skirt 16 integrated with the main frame 14 and the lens 15, and a head strap assembly 17 extending rearwardly from the main frame 14. When the head strap 17 is attached to the user's head, the waterproof sealing skirt 16 can fit snugly over a user's face and seal off the eyes, nose, and mouth from the outside.The outer periphery formed by the main frame 14, the lens 15 and the waterproof sealing skirt 16 encircles from the top of the user's forehead, along the outside of the eyes, through the cheekbones and then the mandible, thus covering the entirety of the user's eyes, nose and mouth. In this way, the entire waterproof sealing skirt 16 closely contacting the user's face generally forms the average fitting height often reaching more than 170 mm under actual measurement. Therefore, four points P1, P2, P3 and P4 having an X shape must be cross-fixed on the main frame 14 to achieve sufficient rigidity and ensure stability when wearing the mask 10, thus preventing it from leaking, being uncomfortable for the user or increasing the risk of use.These four fixed points should be evenly distributed over the circumferential edge of the entire main frame 14. Such a configuration results in the two upper fixed points being approximately distributed above or diagonally above the ocular portion of the main frame 14, while the two lower fixed points should be approximately distributed on both sides of the mouth area of ​​the main frame 14 in order to achieve the balanced fixation of the upper and lower areas, as shown in Figures 1A and 1B. However, the cross-connection of the head with four-point head straps is quite troublesome to put on, take off, and wear, and often may not be easily performed by one person. Additional measures, such as quick release, may be added to compensate for the insufficient . design; however, the cross shape of the head strap 17 itself is not simple enough, so it is still quite inconvenient to use. In particular, during underwater use, if water enters the inside of the mask 10, the user cannot quickly take off the mask 10 to drain the water, which is very uncomfortable and often dangerous. After draining the water, the user must encounter the above-mentioned inconvenience when wearing the mask again. In summary, the four-point type head strap 17 only focuses on one mask stability technology. However, the convenience of putting on or taking off the mask, and the relative safety problems when the mask needs to be quickly removed in emergency situations have never been effectively solved. Summary

[0003] One of the objectives of the present disclosure is to provide a full face diving mask which controls the height of the mask body within a relatively small range, enabling the use of a two-fixed-point head strap to overcome the above problems. The two points fixed to the main frame or the waterproof sealing skirt can be respectively placed on both sides of the eye portion of the mask body. In this way, the mouth and nose area on the lower part of the mask do not have to be designed with other fixing devices.When the two-fixed-point head strap is attached around the back of the user's head, the mouth and nose area of ​​the waterproof skirt can be securely and tightly fitted to the lower part of the user's face (i.e., the part covering both sides of the user's mouth and nose and the chin), without the risk of water entering the mask.

[0004] Another object of the present disclosure is to provide a breathable mask in which the main frame and lens(es) of the mask body are designed to cover only the user's eyes. This design can significantly reduce the volume of the entire mask. In addition, since the rigid parts (i.e., the main frame and lenses) are concentrated in the eye part of the mask body, the softer parts (i.e., the waterproof sealing skirt usually made from silicone rubber) can be just located near the mouth and nose area of ​​the mask body and do not need to extend too much downward. Therefore, it is sufficient to use a head strap with two fixed points and fix it on the two sides of the rigid main frame or the skirt which are close enough to the rigid frame.There is no need for the oral and nasal area, i.e. the lower part of the body, to add further fixing devices. When the two-fixed-point head strap is tightened around the back of the user's head, the lower part of the body can be in contact, in a solid and sealed manner, with the lower part of the user's face, i.e. the . part covering both sides of the mouth and nose and chin, without risk of water entering the mask.

[0005] Yet another objective of the present disclosure is to provide a breathable mask in which the main frame and the lens(es) of the mask body only cover the eyes of the user and at the same time, the height of the mask body is controlled within a small range. In this case, assembling the head strap at two fixed points to both sides of the main frame or the waterproof sealing skirt can not only make the whole mask lighter, but also achieves better effects of wearing convenience and waterproofness.

[0006] In order to achieve the above objectives, the present disclosure provides a full face mask comprising a body and a breathing tube, and the breathing tube is in fluid communication with an interior of the body. The body comprises a main frame, at least one lens which is integrated into the main frame, a waterproof sealing skirt which is partially mounted with the main frame and the lens. The waterproof sealing skirt is configured to fit the face of a user, including the eyes, nose and mouth. The body further comprises a head strap which has two ends fixed on the main frame or the waterproof sealing skirt, wherein the two ends are positioned to correspond respectively to the two outer sides of the eyes of the user.The waterproof sealing skirt has a region that is configured to contact the user's face and having a highest portion and a lowest portion, a center point of the highest portion and a center point of the lowest portion defining a maximum height of between 100 millimeters and 165 millimeters. When the main frame and the at least one lens are configured to cover the user's eyes, nose, and mouth, the maximum height may be determined to be between 140 millimeters and 165 millimeters.When the main frame and the at least one lens are configured to cover only the user's eyes, and the waterproof sealing skirt has an eyepiece portion that is integrated with the main frame and the lens, the maximum height may be further determined to be as low as between 100 millimeters and 150 millimeters, and preferably even lowered to a range between 100 millimeters and 130 millimeters.

[0015] Figures 2A and 2B show the first embodiment of the full face mask of the present disclosure, wherein the main frame and the lens are configured to cover the eyes, nose and mouth of a user. The full face mask 20 includes a body 21 and a breathing tube 22. The breathing tube 22 is in fluid communication with an interior of the body 21. The body 21 includes a main frame 24, a lens 25 which is integrated into the main frame 24, a waterproof sealing skirt 26 which is integrated with the main frame 24 and the lens 25 with its entire surface, thus the waterproof sealing skirt 26 is suitable for fitting over the face of a user, including the eyes, nose and mouth.The body 21 further comprises a head strap 27 which has two ends 271 and 272 attached to the main frame 24 (or attached to the waterproof sealing skirt 26, not shown), and the two ends 271, 272 are positioned to correspond to the two sides of the user's eyes respectively. The waterproof sealing skirt 26 has a region which is configured to be in contact with the user's face and having a highest portion 281 and a lowest portion 282, a center point wl of the highest portion 281 and a center point w2 of the lowest portion, both measured vertically, defining a maximum height (H), preferably between 100 millimeters and 165 millimeters.

[0016] Figures 3A and 3B show a second embodiment of the full face mask of the present disclosure, wherein the main frame and the lens are configured to cover only the eyes (E) of the user. The full face mask 30 includes a body 31 and a breathing tube 32, and the breathing tube 32 is in fluid communication with an interior of the body 31. The body 31 includes a main frame 34, a lens 35 which is integrated into the main frame 34 and a waterproof sealing skirt 36 with its upper portion, i.e., the eye portion which is integrated with the main frame 34 and the lens 35. The waterproof sealing skirt 36 is adapted to fit over a user's face, including the eyes, nose and mouth. The body 31 also includes a head strap 37 which has two ends 371, 372 attached to the main frame 34, the two ends 371, 372 being positioned to correspond respectively to the two outer sides of the user's eyes (as shown in [Fig.4A]). Of course, the two ends 371, 372 of the head strap 37 do not necessarily have to be connected to the main frame 34, but can also be attached to the waterproof sealing skirt 36 on the two outer sides relative to the user's eyes (not shown in the figure). The waterproof sealing skirt 36 has a region that is configured to be in contact with the user's face (as shown in [Fig.4B]) and having the highest portion 381 and the lowest portion 382, ​​a central point wl of the highest portion 381 and a central point w2 of the lowest portion 382, ​​both measured vertically, defining a maximum height (H) which is preferably between 100 millimeters and 165 millimeters.

[0017] In general, regardless of the first embodiment or the second embodiment, the region where the waterproof sealing skirt 26, 36 fits over the user's face is a waterproof ring 28, 38 that encircles the entire face. The waterproof ring 28, 38 may have a two-layer overlapping contour (usually a U-shaped or V-shaped open cross-section or a square or O-shaped closed cross-section, not shown), or a two-layer non-overlapping contour (usually a Y-shaped cross-section, as shown in Figures 2B, 3B and 4B). Also, the region in contact with the user's face has sufficient width to prevent leakage.The above-mentioned maximum height (H) is essentially defined as the distance vertically measured from the center point (i.e., wl) of the highest portions 281, 381 to the center point (i.e., w2) of the lowest portions 282, 382 of the waterproof ring 28, 38.More preferably, in the state in which both the main frame 24 and the lens 25 cover the user's eyes, nose and mouth (i.e., in the first embodiment), the maximum height (H) is between 140 millimeters and 165 millimeters, the two-point fixed head strap (PI, P2) is sufficient to clamp the body on the user's head in a very stable manner, and there is no need to use a chin strap or other means to clamp the chin area of ​​the body on the user's lower jaw, because the height of the entire mask 20 is greatly reduced, while the upper part of the body can be lowered to the user's eyebrows, and the lower part of the body can be close to the mandible bone or even raised to be very close to the user's lower lip (LL).In short, for such a short mask, the user only needs to tighten the mask body with the two-point head straps 37 and a very balanced overall fit of the mask on the face can be perfectly achieved. especially when used underwater, the water pressure coming from the front makes the waterproof sealing skirt even more stable to tightly suck the user's face.

[0018] Taking the second embodiment shown in Figs. 3A, 3B, 4A and 4B as an example, in which the main frame 34 and the lens 35 only cover the eyes (E) of the user (U), as a new model of the breathable mask 30 which has also been provided by the same inventor, the value of the maximum height (H) can be further reduced to an extent of 100 millimeters (mm) to 150 millimeters (mm), and the overall waterproof and balanced effect is even better. Among them, if it is specifically the size for women or children, the value of the maximum height (H) can be as low as between 100 millimeters (mm) and 130 millimeters (mm), so that the two-point head strap 37 can easily tighten the mask 30 against the user's head (U) to achieve a significantly better balancing effect.

[0019] In addition to the above-mentioned preferred embodiments which have detailed descriptions of the structure and operating methods for realizing this inventive technology, any style which is modified based on the same concept, for example, using a different shape, material or quantity of the head strap by modifying it into a multi-strap style, but still fixed with two points (which can be designed to be detachable or non-detachable); or using an additional fixed strap, fixed piece or fixed pad in the chin position of the body in order to further improve the stability of the mask with three-point fixation, and so on, are also a change achievable with the concept of the present disclosure.Additionally, the at least one lens may be an integrated lens that covers only the user's eyes, may be a pair of lenses separated into left and right lenses, or may be a large, one-piece lens for the entire face that covers the user's eyes, nose, and mouth. All of the above possibilities may be an alternative solution and still be within the scope of the present disclosure.
