<p>A spectacle frame (1) comprising a frame front (2) in which two lenses are fixed, and a pair of temple elements (3) connected to the frame front (2) by means · of two respective elastic hinges (4) made so as to force said temple elements (3) into their open position regardless of the initial position of said temple elements (3). Each hinge (4) comprises a hinge pivot (5) comprising a sliding surface (6) on which a hinged end (3a) of the respective temple element (3) slides during a rotation thereof. The sliding surface (6) has an eccentric shape so as to cause a gradual increase in the tension of the elastic hinge when the respective temple element passes from its open position to its closed position. The temple elements (3) comprise respective blocking elements (7) suitable to' cooperate with one another to contrast the elastic action of the hinges (4) and hold the temple elements (3) in their closed position if no additional external force is applied.</p> |
