Abstract

Protective sports eyeglasses with buffer and shock-absorbing function include a cushion (3) having a hollow sealed portion. The cushion encloses a tubular space and is attached on an annular edge of a lens (1) positioned adjacent to the face of a wearer so as to conform to the curvature of the wearer's face. The pressure within the tubular space is preset in advance so that the cushion may contact closely and comfortably to the face of a wearer while acting as a buffer and shock-absorber.

Description

PROTECTIVE SPORTS EYEGLASSES WITH BUFFER AND SHOCK-ABSORBING FUNCTION

BACKGROUND OF THE INVENTION

Common conventional protective eyeglasses such as those used in swimming, diving, cycling, etc. generally have a cushion made of an elastic material such as a sponge or foam rubber to produce soft and comfortable feeling in wearing it on a face.

However, when conventional protective eyeglasses receives strike or shock, a wearer may suffer pain, harm or wound because of poor elasticity the cushions have, limited by its thickness and its elasticity coefficient.

SUMMARY OF THE INVENTION

In view of the disadvantages aforesaid of the conventional protective eyeglasses, this invention has been devised to offer protective sports eyeglasses with buffer and shock-absorbing function, which has a cushion of hollow 3D space attached with a frame or a lens so as to produce soft and comfortable feeling in wearing it.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

A first preferred embodiment of protective sports eyeglasses with buffer and shock-absorbing function in the present invention, as shown in Figs. 1 - 6, includes a lens I and a frame 2 independent from each other and able to be firmly combined together. Further, a cushion 3 is provided with the lens I on the side contacting with the face of a wearer, formed integral with the lens at its peripheral edge, and having a hollow interior. The cushion 3 is shaped as an annular hollow 3D ring, sealed and endless, so its route is not a surface. Further, the cushion 3 is filled with a preset pressure, permitting it contact the face of a wearer steadily and comfortably because of 3D curvature of the cushion 3. having buffer and shock-absorbing effect. The cushion 3 is made of materials having high density and low percolation, selected from poly amide, polyethylene, PolyproPelene, acetic salt of ethylene, polyester, polyamide, Polyurethane, chlorinated polyethylene, or butyl rubber. Or materials having good elasticity, flexibility, anti-low-temperature, and easy processibleness can be used as well. A second preferred embodiment of the protective sports eyeglasses with buffer and shock-absorbing function in the present invention is shown in Figs. 7 - 11, includes a lens 1 and a frame 2 formed integral with the lens 1 , and a cushion 3 made independent to be attached on the frame 2. The cushion 3 is an annular hollow 3D ring with a preset curvature, not a flat two dimensions (2D). The hollow interior of the cushion 3 is filled with air pressure of a preset value. The frame 2 has an annular groove 21 of a preset size for the cushion 3 to fit therein with close fitness and stability.

Another preferred embodiment of that shown in Fig. 7 is shown in Figs. 12 and 13, includes a lens 1 , a frame 2 having a flat surface without an annular groove 21. The annular flat surface of the frame 2 should be wide enough for attaching the cushion 3 thereon.

The cross-section of an inner or the outer shape at any point of the hollow 3D cushion 3 is all the same or not the same, of any geometric shape. As the cushion 3 is made to have a hollow 3D shape closely contacting the face of a user, and a preset pressure in the hollow interior to minimize sport harm or wound with its buffer and shock-absorbing function in practical use, thus Protecting the face from hurt.

The inner buffer pressure filled in the cushion 3 may be preferably in the scope of 0 - 40 psi, and then different buffer pressure can be selected for different objects and different conditions, able to be chosen by consumers. So at least one hollow passageway 30 may be added to the cushion 3, communicating the cushion 3 with outer air. as shown in Figs. 14 - 16, for connecting an air valve 301, a valve, a pump, or the like so as to fill the hollow interior of the cushion 3 with a gas, a semi-fluid, a fluid, a liquid or low-percolating large particle gas such as SF6, C2F6, etc.

An inner pressure of the cushion 3 not communicating with outer air is produced with a special method, such as a process with a hollow mold placed in an air pressure container, forming a sealed cushion 3 with the same inner pressure as that in the air pressure container, which is preset in advance.

While the preferred embodiment of the invention have been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications which may fall within the spirit and scope of the invention.
