| Abstract: |
A hinge for use with molded plastic parts and, in particular, for spectacles comprises two parallel bosses with sockets therein forming a part of the spectacle frame. A temple body has two pin arms formed thereon each pin arm including a projecting pin. A slot separates the two pin arms and permits assembly of the hinge. A pin arm locking bar is formed as a part of the temple body and is attached thereto by a web thin enough to be flexible. Cooperating locking means are formed on the locking bar and the pin arms. When the projecting pins are located in the sockets in the bosses and pin arm locking bar is forced between the pin arms, a simple permanent hinge is formed.
