ABSTRACT OF THE DISCLOSURE The invention is for an improved hinge for pivotably connecting an eyeglass temple piece to an eyeglass frame, which permits a stable positioning of the temple piece in a folded or closed position in order to conveniently store the eyeglasses and a stable positioning of the temple piece into a normal open posi- tion for wearer use of the frame and which permits still further elastic movement of the temple piece beyond the normal open posi- tion without damage to the frames or hinge. The improved hinge includes a rod-shaped slide which is slideably mounted in a seat provided in the end portion of the temple piece and which pro- trudes from the seat. A hole is formed in the slide which extends coaxially in the slide over a predetermined depth from its pro- truding end. A slot is formed in the slide which extends longi- tudinally in the slide over a predetermined length from its pro- truding end. The predetermined length of the slot is less than the depth of the hole in the slide and the slot debouches in that hole. A block is fastened transversely at the mouth of the seat, extends through the slot and constitutes an axial guide for the slide. A spring is mounted in the hole in the slide having an end in pressing contact with the block and another end in press- ing contact with the bottom wall defining the hole.
