Title: Hinge structure for use in joining temple and front rim in eyeglasses

Abstract: Disclosed is an improved hinge structure for joining a temple and a front or lens rim together in eyeglasses. It comprises two semicolon-like rotary pieces each having a step-like circular extension integrally connected to its triangular block. The step-like circular extension has a through hole made therein. The semicolon-like rotary pieces are so combined that their step-like circular extensions are laid on each other, with a flat washer sandwiched therebetween. The semicolon-like rotary pieces are joined together by inserting a pivot pin in the through holes of the step-like extensions with another flat washer laid on one side of the so combined rotary pieces, and with the outward-curved resilient washer laid the other side of the so combined rotary pieces. The pivot pin is swaged against the so combined rotary pieces. The triangular blocks of the rotary pieces are to be fixed to the temple and the front or lens rim of the frame.
