Eyeglass frame with internal spring and slider assemblies

Abstract

Disclosed is an eyeglasses frame using temple joints improved according to the present invention. Each hinge assembly is fixed to the joint piece of either side of the frame. It comprises an engagement piece having an axle transversing in its recess end, and a hollow sheath having a lever pivotally fixed to its open end and a spring-biased slider contained therein. The slider has a hook end. The engagement piece is fixed to the joint piece, and the sheath is fixed to the temple. The temple is connected to the front by inserting the hook of the slider in the recess of the engagement piece, and then the temple is pulled to the engagement piece by the resilient force, which is applied to the slider all the time. Thus, the temple-to-front connection is assured to be tight, still permitting the stable opening-and-folding of the temple relative to the front.
