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. I -
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
1 o 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 polyamide.
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
2 0 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
2 o 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.
