Abstract
Spaced prong arms, spring loaded toward an initial position, are moved relative to fixed prong arms, against the spring force, to a position for engagement of opposing sections of the eyeglasses frame. The ends of the prong arms are shaped to receive the frame. The spring force causes the prong arms to securely retain the eyeglasses frame. In one embodiment, the moveable prong arms are associated with a coil spring. Movement of the prong arms compresses the spring, which urges the prong arms toward an expanded position. In a second embodiment, the moveable prong arms are leaf springs. The springs flex to permit the frame to be inserted. The ends of the prong arms may be plastic coated to protect the eyeglasses frame.
