Abstract
A side arm for an eyeglass frame includes front frame having outer edges, each of the edges terminating in a vertical line parallel to a plane defined by the eyeglasses held within the front frame. The vertical line functions as a fulcrum for the release function. The system further includes a pair of axle journals, and a pair of male bayonet clips, each rotationally dependent at one end from axles within respective the journals of the eyeglass frame. Each of the temple pieces exhibit a forward end terminating in a vertical camming surface which contacts the fulcrum upon rotation of temple members. A pair of female bayonet clips are proportioned for complemental engagement of opposing male bayonet clips, the female clips formed integrally upon inner sides of each temple piece proximally to each of the male bayonet clips when the male clips are press-fitted into the female clips.
