ABSTRACT:
A pull-down member is pivotably and ratchetly attached to the distal end of the end-piece of each eyeglass temple. Each pull-down member is pivotably displaceable to the end-piece at a series of angles, and thereby provides a snug fit of the eyeglasses on the user's face. In one embodiment, the pull-down member comprises a disk-shaped core having an edge on which is attached an elongated appendage which is the portion of the pull-down member abutting against the user's ear. The edge of the core also includes a series of notches which are biased by a ball and spring mechanism to provide the pivotable and ratchetable displacement of the pull-down member relative to the end-piece of the eyeglass temple. In another embodiment of the pull-down member, the core has a central opening defined by a series of teeth. A split-pin having a complementary series of teeth along an outer surface thereof engages the toothed opening of the core to provide the pivotable and ratchetable displacement of the pull-down member relative to the end-piece of the eyeglass temple.
