ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a metal temple structure for eyeglasses. Conventional metal temples for eyeglasses can be roughly classified into two groups—one temple is made of relatively broad low-elasticity metal material and the other temple is made of fine wire-formed high-elasticity metal material. The temple made of low-elasticity metal material has the disadvantage of requiring to make up for the insufficient resiliency a relatively broad spring hinge, which causes the weight to be increased, resulting in an increased load on the ears and nose of an wearer. In contrast, the temple made of fine wire-formed high-elasticity metal material is sufficiently resilient to eliminate the use of such a spring hinge as required for the temple mentioned above as the first group, but has the disadvantage of tending to be relatively low in strength, undergoing deflection when they hold a spectacle front frame, the weight of which exceeds a certain level. They also have the disadvantage of allowing little design modification.
The present invention, therefore, improves the strength of the temples mentioned above as the second group with maintaining their lightweight and resilience.
SUMMARY OF THE INVENTION
An object of the present invention is the provision of a new metal temple structure for eyeglasses, which overcomes the disadvantages of the conventional temples mentioned above as the second group, thereby providing flexible temples while maintaining the resilience of such conventional temples.
In one preferred embodiment of the present invention, the temple structure for eyeglasses thereof mainly comprises a spring hinge box, a piece of elastic metal wire folded in two, a flange connecting said spring hinge box and said piece of elastic metal wire, and an ear chip. Said spring hinge box has a one-piece knuckle and a hollow with an opening, which houses a spring hinge member connected to said one-piece knuckle, on its front side, and a longitudinally frontward threaded hole at the end of its rear side. Said piece of the elastic metal wire folded in two is designed to have its two free ends located near the ear of a wearer with its head portion positioned on the side face of said spring hinge box and its arm portion formed in a streamline or tear-drop shape to have a hollow with an opening. Said flange, provided with a screw hole, is positioned in said hollow with an opening, through which a screw is driven into the threaded hole provided at the rear end of the spring hinge box, thereby fixing the piece of elastic metal wire onto the side face of the spring hinge box. Said two free ends of the piece of the elastic metal wire are fit in said ear chip.
