Waterproof structure for water goggles and swimming goggles

The invention relates to a waterproof structure of water goggles and swimming goggles, in particular to a waterproof structure of water goggles and swimming goggles, which can adjust the tightness of the wearing of the water goggles and swimming goggles to the human face and provide a comfortable wearing experience.

When performing underwater activities, users will wear water glasses to prevent water from entering their eyes, so as to facilitate underwater activities. As shown in Figs. 1 and 2, a rear view and a cross-sectional view of the conventional water mirror 1, respectively. The conventional water mirror 1 will directly bend a skirt 11 of the mask 10 to form a close face 12, by Facial surface 12 fits the human face.

As shown in the cross-sectional view of the conventional water mirror 1 in FIG. 2, the face-contacting surface 12 will present an inwardly curved surface similar to a trumpet-like structure, and the bend 12R of the face-contacting surface 12 is slightly rounded to modify its outline. It does not provide substantial functionality.

Due to the simple structural defects of the above-mentioned conventional mask 10, it is often faced that the user wears it too tightly or encounters excessive water pressure due to diving, and the close-up face 12 will over-press the human face. Once the conventional mask 10 is removed, the face is Deep impressions are left, so wearing the conventional water mirror 1 tends to make the user feel uncomfortable.

In view of the above-mentioned shortcomings, the present invention provides a waterproof structure for water goggles and swimming goggles, which is more comfortable to use and has the function of adjusting the tightness of wearing, which is an urgent need of the industry.

In order to solve the foregoing problem, one object of the present invention is to provide a waterproof structure for water goggles and swimming goggles. The reflexed area is formed by a special structure design to form a buffer space, so that when the user wears it, the user can adjust the face on the face according to personal preference. Tightness. At this time, the buffer space can be adjusted accordingly to match the user's face shape and provide comfortable wearing.

To achieve the above object, the present invention provides a waterproof structure for water glasses and swimming glasses, which includes at least one lens group and a mask portion. The mask portion defines a first portion and a second portion. The first portion is engaged with and supports at least one lens group, and the second portion is located in a skirt portion of the mask portion to fit on the human face. Wherein, the second portion is bent toward an inner side surface of the mask portion to form a contact surface that fits with the human face and a curved surface composed of at least one radius of curvature, and the contact surface of the second portion and the mask A buffer space is created between the inner side surfaces of the part, and when the contact surface is stressed, the buffer space can be compressed.

In order to make the foregoing objects, technical features, and advantages of the present invention more comprehensible, the following describes in detail the preferred embodiments in conjunction with the accompanying drawings.

The content of the present invention will be explained below through the examples. However, the descriptions in the examples are only for explaining the technical content of the present invention and its effects, and are not intended to directly limit the present invention. It should be noted that in the following embodiments and illustrations, components that are not directly related to the present invention have been omitted and not shown; and the dimensions and relative positional relationships of the components in the illustration are for illustration and understanding only, not for Restrict implementation ratio and size.

Please refer to FIG. 2 and FIG. 3, which respectively show a perspective view and a rear view of this embodiment. In the following embodiments, the application principle of the waterproof structure of the mask of the present invention is described in detail with a water mirror, of course, as usual in the technical field It can be easily reached by a knowledgeable person, and the following embodiments are also applicable to swimming goggles.

Referring to FIG. 2 and FIG. 3, this embodiment includes at least one lens group 20 and a mask portion 21. The mask portion 21 may define a first portion 211 and a second portion 212. The first portion 211 is engaged with and supports at least one lens group 20, and the second portion 212 is located at a skirt portion 210 of the mask portion 21 for Fits to the human face.

It should be noted that although the first portion 211 of the mask portion 21 in the drawing of this embodiment is engaged with and supports the two lens groups 20, as understood by those skilled in the art, the first portion of the mask portion 21 211 can also engage and support a single lens group 20.

Refer to FIG. 4A, which is a cross-sectional view of the mask portion 21 according to the line segment B-B of FIG. 3 to illustrate the embodiment of the present invention. A second portion 212 that blocks water penetration is formed at the position of the skirt portion 210 of the mask portion 21, and the first portion 211 and the second portion 212 are integrally formed. The second portion 212 extends toward an inner side surface 21s of the mask portion 21 and is bent. . Thereby, the bent second portion 212 is configured with a contact surface 212a that is in contact with the human face and a curved surface 212R formed by at least one radius of curvature, and the contact surface 212a of the second portion 212 and the mask portion 21 The inner side surface 21s can generate a buffer space P.

Specifically, the present invention specifically allows the curved surface 212R of the second portion 212 to be composed of at least one radius of curvature, effectively improving the smoothness of the curved surface 212R, and avoiding the sharp bend directly contacting the user's face. The most important thing is that the structure of the curved surface 212R can support the contact surface 212a and produce a curved surface elasticity; that is, when the external force acts on the contact surface 212a, the curved surface 212R supports the contact surface 212a elastically, so the contact surface 212a can be elastic. To the human face. Therefore, the structural design of the curved surface 212R of the second portion 212 greatly improves the wearing comfort of the water goggles and the swimming goggles.

On the other hand, since the contact surface 212a of the second portion 212 and the inner side surface 21s of the mask portion 21 create a buffer space P, the user can adjust the tightness of the water mirror attachment face by compressing the distance between the buffer space P . Furthermore, when the water mirror 2 is subjected to external water pressure or accidental collision, the buffer space P of the second portion 212 can also absorb the external pressure to reduce the direct impact of the water mirror 2 on the face.

To achieve the effect of curved surface elasticity, at least one curvature radius of the curved surface may be between 1 mm and 10 mm. As shown in a partially enlarged view of the second part 212 in FIG. 4B, the curved surface 212R in this embodiment is composed of three curvature radii R1, R2, and R3, but the curved surface of the present invention is not limited to the current drawing. The number and size of the curvature radius can be adjusted according to different parts of the human body corresponding to the mask.

In order to achieve the buffering effect, the minimum distance D1 of the buffer space P is not less than 3 mm, so as to prevent the elasticity of the second portion 212 from being poor, and the maximum distance D2 is not more than 30 mm, so as not to cause the second portion 212 to deform. It should be noted that the positions of the minimum distance D1 and the maximum distance D2 are not limited to FIG. 4B. In principle, the minimum distance D1 is located at the opening N formed between the end 212d of the second portion and the inner side surface 21s of the mask portion 21.

As understood by those having ordinary skill in the art, the entire mask portion is generally made of an elastic material having the same hardness. However, when the mask part is made of an elastic material with too little hardness, although it can be more softly attached to the human face, it is easy to deform and cannot effectively support the lens group; if it is made of an elastic material with too much hardness, it will sacrifice wearing comfort.

In order to overcome the above disadvantages and adapt the second part 212 to different softness of the human face, the present invention adopts a design in which the hardness of the second part 212 is not greater than that of the first part 211, and the hardness of the first part 211 (Shore A ) Is 50-80 degrees, and the hardness (Shore A) of the second portion 212 is 20-50 degrees. Therefore, when the hardness of the second part 212 is smaller than that of the first part 211, the contact surface 212a of the second part 212 can be softly attached to the human face, and the first part 211 with high hardness can also effectively support the lens group 20 weight.

Alternatively, when the first part 211 and the second part 212 have the same hardness, the elasticity of the curved surface 212R and the buffer space P of the contact surface 212a can still provide a comfortable wearing experience for the user.

In addition, the first part 211 and the second part 212 can also be matched with different colors to increase the overall visual effect.

In another embodiment, the contact surface of the present invention may also be composed of at least one radius of curvature, and form a circular arc-shaped second portion with continuous curvature with the curved surface. This part is illustrated by Figure 5 as follows:

As shown in Fig. 5, in addition to the curved surface 312R being composed of a plurality of curvature radii R1 'and R2', the contact surface 312a is also composed of a curvature radius R3 '. In particular, the contact surface 312a is an arc-shaped curved surface protruding toward a direction away from the inner surface of the 31s of the mask portion 31 to form a second portion 312 of continuous curvature with the curved surface 312R. In other words, the second portion 312 will form a semi-circular arc-shaped outline as a whole, and the minimum distance D1 'is located at the opening N' formed between the end portion 312d of the second portion 312 and the inner side surface 31s of the mask portion 31, thereby more An excellent buffer space P 'can be obtained. As mentioned above, the minimum distance D1 'of the buffer space P' is not less than 3 mm, so as to prevent the elasticity of the second portion 312 from being poor, and the maximum distance D2 'is not more than 30 mm, so as not to deform the second portion 312. As for the curved surface 312R, it is not limited to the figure 5. According to the different parts of the mask corresponding to the human body, the number and size of the curvature radius can be adjusted, and the curvature radius is between 1mm and 10mm to obtain the best flexibility. .

In summary, the mask portion of the present invention provides the user with the ability to directly and easily adjust the tightness of the wearing of the water goggles and swimming goggles through the buffer space of the second part and the curved elasticity of the curved surface. Effectively reduce pressure and discomfort during wearing.

The above embodiments are only used to exemplify the implementation of this creation, and to explain the technical features of this invention, but not to limit the scope of protection of this creation. Any change or equivalence arrangement that can be easily accomplished by those skilled in this technology belongs to the scope claimed by this creation, and the scope of protection of the rights of the present invention shall be subject to the scope of patent application.
