A spectacle frame of the type comprising a central bridge (9) interconnecting the lenses (1, 2) and disposed in the region of the user's nose for which it has bearing elements (12, 13), the central bridge (9) being provided with fixing elements (7, 8) for connection to both lenses (1, 2) on their inner sides facing towards the user's nose, the frame also comprising two side fixing elements (10, 11) each fixed to the outer side of a respective lens and having a respective support (14, 15) for articulation to the arm (16, 17) for bearing on the user's ear, the fixing elements (7, 8) of the central bridge and the side fixing elements (10, 11) having respective plates (20) for bearing on the facing rims (3) of the lenses, and pieces of resilient wire or thread (5, 6) connecting the fixing elements (7, 8) of the central bridge to respective side fixing elements (10, 11), the pieces (5, 6) of resilient wire or thread extending around the rims (3) of the lenses in a peripheral groove formed within the thickness of each lens, fixing the lenses firmly to the elements. The plate (20) of each fixing element for bearing on the rim (3) of the respective lens has a pair of opposed flanges (21, 22) projecting from the bearing plate (20), fixed firmly thereto, and grasping the thickness of the lens (1, 2) so as to be fixed thereto, the plate (20) being extended longitudinally along the periphery of the lens by opposed portions (23, 24) the bearing surfaces of which are shaped so as to match the shape of the periphery of the lens in the specific region in which bearing takes place. The means for anchoring the ends of each piece of resilient wire or thread (5, 6) comprise a head (5a, 6a) provided on the end of each piece of wire or thread to be anchored and having a diameter greater than the diameter of the wire or thread, a hole (25, 26) extending through the thickness of the respective one of the opposed portions (23, 24) of the bearing plate (20), as well as a lateral slot (29, 30) which renders the hole (25, 26) accessible from the edge (27, 28) of the portion of the plate, the width of the slot (29, 30) and the diameter of the hole (25, 26) being substantially equal to the diameter of the wire or thread but less than the diameter of the head (5a, 6a) on the end of the wire or thread to be anchored. The frame also provides for one (21) of the flanges grasping the thickness of the lens to have a small screw (33) the longitudinal axis of which extends substantially perpendicular to the plane of the lens and the tip of which has a pad (34) of soft material. <IMAGE> |
