ABSTRACT:
The elastic hinge comprises a hinge element (5) fixed to the front part of a spectacle frame and a hinge element (8) integral with a rod (11) inserted in the bore (9) of a housing (10). The rod (11) is pressed to the rear of the temple by a spring (16) which presses on the one hand against a collar (17) integral with the rod (11) and on the other hand against a ring (25) having a rib (26) which engages elastically on a shoulder (27). As a result of this arrangement, the fitting of the elastic assembly in the bore (9) is substantially simplified.
