Description

EYEGLASSES HINGE

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spectacle hinge, and more particularly, to a spectacle hinge that moves by the interaction of a leaf spring and a cam.

The hinge of existing glasses is a method of assembling eyeglass legs and eyeball front part using screws and hinges. However, when using the hinge of the existing glasses, the legs of the glasses are continuously folded and repeatedly repeatedly moved, the screw is loosened naturally. If this is done, the screw is easily lost and the glasses can not be worn normally .

As such, the conventional spectacle hinge can not be easily disassembled by using a screw, and it is difficult to find a different point from other glass products because it is uniform in design. When a coil spring or a rubber band is inserted into a hinge portion for a good fit feeling, There is a problem that it is necessary to replace the entire leg when a failure occurs.
