HINGE MECHANISM OF A PAIR OF SPECTACLES

摘要

A hinge mechanism of a pair of metal frame (or rimless) spectacles provided between the temple and the wraparound endpiece in order to make thin the temple or the wraparound endpiece and to develop a hinge mechanism of simple structure, characterized by the being provided with a structure for clamping an annular pivot ring to a clamp ring, formed by stacking a plurality of annular structures having inner circumference substantially touching the outer circumference of the pivot ring, and coupling/turning them. The hinge mechanism of a pair of spectacles characterized in that the clamp ring is constituted by brazing a plurality of annular rings to the end part of a component of spectacles, and characterized in that the part where the plurality of annular rings are brazed to the end part of a component of spectacles becomes an opening stop mechanism.
