ABSTRACT:
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 position for wearer use of the frame and which permits still further elastic movement of the temple piece beyond the normal open position 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 protrudes from the seat. A hole is formed in the slide which extends coaxially in the slide over a predetermined depth from its protruding end. A slot is formed in the slide which extends longitudinally in the slide over a predetermined length from its protruding 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 pressing contact with the bottom wall defining the hole.
