ABSTRACT:
The front part (1) of the spectacle frame carries a body (10) embedded in synthetic resin, the body containing a spring (14) and a ball (15) and having legs (11) to form a hinge part. The other hinge part is solid with the arm (2) and carries a cam shape (7) provided with notches (8 and 9) for defining the folded and normal opening positions. A spacing (22) facing the front end of the arm makes it possible to unfold the latter beyond.
