DESCRIPTION OF THE PREFERRED EMBODIMENT

[0032] It shall be appreciated that the following description of the embodiments is only to explain the contents of the present invention, but not to limit the invention as claimed. Elements not directly related to the present invention are omitted from the description, and the dimensions as depicted for all elements in the drawings are just for easy understanding and do not intend to limit their actual scales. In addition, the used front, back, left, right, inner, outer, or the like adjectives defined in the descriptions are referred to by the direction of the user himself/herself. They are only relative relationships and are not limitative.

[0033] An embodiment of a mask 3 (e.g., a water sports mask) of the present invention is shown in FIGS. 3A and 3B and FIGS. 4A and 4B. In this embodiment, the mask 3 is exemplified by a dual-viewing windows mask.

[0034] Reference is made to FIG. 3A, in which the mask 3 includes two transparent viewing window modules 31L, 31R, a frame portion 33 and a waterproof skirt 35. Preferably, a fastener 36 is provided on both sides of the waterproof skirt 35 to allow a head strap (not shown) to be fastened to them, respectively. The frame portion 33 may include a main frame 33M and a sub-frame 33S. The waterproof skirt 35 has a front portion 351 being embedded with the transparent viewing window modules 31L, 31R and a rear portion 353 being configured to water-tightly fit a face of a user.

[0035] The frame portion 33 may be made of a rigid material. The rigid material is selected from polycarbonate (PC), polyoxymethylene (POM), acrylonitrile butadiene styrene copolymer (ABS), polyvinylchloride (PVC), polyethylene (PE), polypropylene (PP) or combinations thereof. The waterproof skirt 35 may be made of silicone rubber material.

[0036] To assemble the mask 3, the front portion 351 of the waterproof skirt 35 can be embedded with the main frame 33M first, and the transparent viewing window modules 31L and 31R can then be installed from the front to the back into the main frame 33M, and then the sub-frame 33S can be joined with the main frame 33M from the front to the back. At this time, as exemplarily illustrated in FIG. 3B, the front portion 351 of the waterproof skirt 35 is water-tightly embedded with the main frame 33M and the transparent viewing window module 31L.

[0037] The transparent viewing window module 31L is shown in FIGS. 4A and 4B. Since the transparent viewing window module 31R and the transparent viewing window module 31L have the same composition and may only differ in shape as mirror images due to their left and right configuration, the following description will use the transparent viewing window module 31L as an example for illustration. However, in fact, it should be understood that depending on the appearance design of the mask, the transparent viewing window modules 31R and 31L may be different in shape or be completely identical. Both designs are applicable to the present invention as long as they have substantially the same composition.

[0038] The transparent viewing window module 31L includes a glass viewing window 41 and an integrally-formed transparent encapsulation layer 43. The glass viewing window 41 may be made of a tempered glass. The glass viewing window 41 includes an inner surface 411, an outer surface 413 opposite to the inner surface 411 and a peripheral portion 415. The integrally-formed transparent encapsulation layer 43 fully and tightly encompasses the peripheral portion 415 and the inner surface 411 (i.e., the surface proximal to the user's eyes) of the glass viewing window 41. Preferably, the integrally-formed transparent encapsulation layer 43 is directly integrally formed on the peripheral portion 415 and the inner surface 411 of the glass viewing window 41 through an injection-molding process. The peripheral portion 415 is defined by an outer contour of the glass viewing window 41, and it may only include one side surface 417 of the glass viewing window 41. Alternatively, it may also include an outer edge 413e of the outer surface 413.

[0039] Instead of directly injecting a transparent encapsulation layer 43 to encapsulate an already formed glass viewing window 41, in another embodiment, a glass viewing window can first be formed through a glass injection-molding process using either the same or a different machine. Subsequently, a transparent encapsulation layer 43 is integrally injection- molded onto the peripheral portion 415 and the inner surface 411 of the glass viewing window 41 through an injection-molding process, thereby directly constructing the transparent viewing window module 31L.

[0040] The integrally-formed transparent encapsulation layer 43 may be made of thermoplastic and has a Shore D hardness ranging between 40 and 90. Alternatively, it may be made of thermosetting silicone rubber and has a Shore A hardness between 10 and 90. However, it is not limited to these materials, and any transparent, lightweight, non-glass materials are feasible. For example, the thermoplastic may be selected from polycarbonate (PC), polypropylene (PP), polyoxymethylene (POM), acrylic, acrylonitrile butadiene styrene (ABS), nylon or combinations thereof. Herein, the transparent non-glass material refers to a material that does not impede the user's view and may be tinted or colorless.

[0041] In the embodiment of the transparent viewing window module 31L without vision correction function (i.e., plano), the glass viewing window 41 has a thickness ranging between 0.3 and 4 mm, and the integrally-formed transparent encapsulation layer 43 has a thickness ranging between 0.3 and 4 mm. Preferably, the thickness of the glass viewing window 41 ranges between 2 and 4 mm, and the thickness of the integrally-formed transparent encapsulation layer 43 ranges between 1.5 and 4 mm. When the transparent viewing window module 31L is provided with a vision correction function, the present invention requires only modifying the shape and thickness of the integrally-formed transparent encapsulation layer 43, particularly the thickness and curvature of the portion (which can be referred to as the functional portion) attaching to the inner surface 411 of the glass viewing window 41. Consequently, the integrally-formed transparent encapsulation layer 43 can provide diopter correction for the user's eyes without altering the glass viewing window 41, thereby achieving the objective of lightweight design. In other words, the integrally-formed transparent encapsulation layer 43 may have a functional portion tightly encompassing the inner surface 411 of the glass viewing window 41, which serves as a vision correction layer.

[0042] In addition, since the integrally-formed transparent encapsulation layer 43 of the present invention not only encapsulates the peripheral portion of the glass viewing window 41 but also its inner surface 411 (i.e., it is in contact with and flat against the inner side of the glass viewing window 41). Therefore, it can effectively prevent glass fragments from being flown toward the user in the event of the glass viewing window 41 breaking so as to provide effective protection for the user, particularly for the user's eyes. In addition, the integrally-formed transparent encapsulation layer 43 may be made of materials with inherent anti-fog or UV-resistant properties, providing anti-fog or UV-resistant functions to further enhance the added value of the mask 3. In practice, even if the integrally-formed transparent encapsulation layer 43 does not provide anti-fog or UV-resistant properties, the material of the integrally-formed transparent encapsulation layer 43 (e.g., PC) is easier to be coated with an anti-fog layer or other functional layers than the glass material. Therefore, the integrally-formed transparent encapsulation layer 43 can provide more added benefits to the mask 3 in practical applications.

[0043] The above embodiment mainly takes the mask 3 as a dual-viewing windows mask for illustration. However, based on the detailed description above, it can be understood that the single-viewing window mask of the present invention can simply include a transparent viewing window module and a waterproof skirt. The assembly of the single-viewing window mask may be achieved by directly injection-molding the waterproof skirt onto the transparent viewing window module (i.e., the front portion of the waterproof skirt is embedded with the transparent viewing window module), thereby providing considerable strength of product. However, in practice, adding a frame portion to enhance the overall strength of the mask is also feasible.

[0044] For example, as shown in FIG. 5, the single-viewing window mask 5 includes a transparent viewing window module 51, a frame portion 53 (optional) and a waterproof skirt 55. Likewise, a fastener 56 is preferably provided on both sides of the waterproof skirt 55 to allow a head strap (not shown) to be fastened to them, respectively. The waterproof skirt 55 has a front portion 551 being embedded with the transparent viewing window module 51 and a rear portion 553 being configured to water-tightly fit the face of a user. Since the transparent viewing window module 51 has the same composition as the transparent viewing window modules 31L, 31R and may only differ in shape and size, it will not be further described herein.

[0045] It shall be appreciated that in the drawings, elements not directly related to the present invention, or elements (such as the head strap that ties up the user's head) which may influence the comprehension, are omitted from the illustration. And, the dimensional proportions among individual elements in the drawings are provided only for one of the aspects but not to limit the present invention.

[0046] Among various masks for scuba diving or snorkeling, those that only cover the user's eyes and nose, most often use glass as the material of the viewing window. Therefore, the mask of the present invention is designed to encapsulate the glass viewing window with a non-glass material (e.g., plastic) instead of just using the conventional single glass viewing window. This not only effectively prevents injuries caused by accidental breakage of the glass viewing window but also provides vision correction, anti-fog, and UV-resistant functions without significantly increasing the overall weight of the mask, thereby maximizing its effectiveness.

[0047] Any modifications based on the above core technology of the present invention are intended to be protected. Consequently, the above embodiments are used only to illustrate the implementations of the present invention and to explain the technical features of the present invention and are not used to limit the scope of the present invention. Any modifications or equivalent arrangements that can be easily accomplished by those skilled in the art are considered to fall within the scope of the present invention, and the scope of the present invention should be limited by the claims of the patent application.
