Claim:
A spectacle frame comprising a front side, extended by two side tenons and two side-pieces jointed on the tenons about joint axes of two telescopic hinges, each telescopic hinge having a front side element being integral with a tenon and a side-piece element being integral with a side-piece, the side-piece element of each telescopic hinge comprising a slide having a front end jointed on the front side element about the associated joint axis and a back portion mounted slidably in a sheath against and under the action of a spring so that the sheath can move relative to the slide and is biased by the spring toward the associated joint axis, the front side element and the sheath of the side-piece element of the hinge each having a transversal opening rest surface substantially parallel to the joint axis of the hinge, such frame being characterized in that the opening rest surface of one of the front side and side-piece elements having a recessed intermediary area, the opening rest surface of the other of the front side and side-piece elements having a raised intermediary area, the opening rest surfaces of the front side element and side-piece element of each hinge being complementary to one another so as to match with one another when the side-piece is in an opening position.
