The invention relates to a spectacle frame comprising sliding hinges which enable the arms to move from a stable open position, in which the end (306) of the arms is parallel to the end (313) of the endpiece (307), to an unstable wide-open position, by pivoting around a support point (311) belonging to a coincidence plane (P,P') which passes between the knuckles (C1, C2) of the hinges.The inventive frame, which has a plane of symmetry (X,X'), is characterised in that the support point (311) is located closer to the plane of symmetry (X,X') of the frame than the outer face (309) of the arms at the coincidence plane (P, P').
La monture comporte des charnières télescopiques permettant aux branches de passer d'une position d'ouverture stable, dans laquelle l'extrémité (306) des branches est parallèle de l'extrémité (313) du tenon (307), à une position de sur-ouverture instable par pivotement autour d'un point d'appui (311) appartenant à un plan de coïncidence (P,P') passant entre les charnons (C1,C2) des charnières. La monture qui a un plan de symétrie (X,X') se caractérise par le fait que le point d'appui (311) est situé plus près du plan de symétrie (X,X') de la monture que la face extérieure (309) des branches prise au niveau dudit plan de coïncidence (P,P').
