ABSTRACT:
A spectacle frame includes two side extensions each having a channel for rotatably receiving two rotary members. A pair of legs are secured to the outer rotary members. A resilient ring is engaged around the rotary members so as to couple the rotary members together. The extensions each includes a curved slot for receiving a rod of an outer rotary member. When the rod is moved along the curved slot against the ring, the ring may relatively bias the outer rotary member and the legs backward to working position so as to form a resilient coupling.
