Frame for spectacles has lenses held in place by U-shaped wire staples with deformed ends to retain lenses

摘要

The frame for spectacles is made from one or more sections (1-3) and has at least one hole (12). the lenses (4,5) also have a hole (13) to receive a wire staple (6). The staple is U-shaped and the ends are deformed to prevent it loosening from the holes. The wire diameter is slightly smaller than the hole size to allow the staple to be pushed into place.
