Mount for spectacles

Mount for spectacles comprising a front frame (2) having a pair of structures (4) for holding lenses (3), said pair of structures are connected by a central bridge (5) extending in a nasal support zone, each structure of said pair of structures (4) comprising:

• an upper element (8) for holding the lens (3), configured so as to surround at least a part of a lens profile at a top portion, in a brow arch zone, between the central bridge (5) and a corresponding opposite lateral tenon (6) connectable to a lateral arm (7) so as to articulate about an axis of articulation (X), said upper element (8) being integral with the bridge (5) and the corresponding lateral tenon (6),
• a lower element (9) for supporting the lens (3), said element extends so as to surround the remaining part of the lens profile at a bottom portion between the bridge (5) and the corresponding lateral tenon (6), said lower element (9) having a first end (9a) connected to the front frame (2) at the central bridge (5) and a second, opposite end (9b) configured to be constrained to the lateral tenon (6),
• a corresponding box-shaped body (11) received in each tenon (6) and guided so as to slide to a limited extent in a vertical direction that is substantially parallel to the direction of the axis of articulation, said second end (9b) of the lower support element (9) being constrained to said box-shaped body (11), and
• a surface (13) having a predetermined incline with respect to the vertical sliding direction defined on said body (11), against said surface a screw (16) is active which is screwed in a hole (15) provided in the tenon (6) and directed transversely to the vertical sliding direction, so as to transform a translational movement of the screw (16) with respect to the tenon (6), said movement is created by the screwing or unscrewing of said screw, into a translational movement of said body (11) in the sliding direction, and to subsequently move the lower support element (9) towards or away from the upper support element (8), in order to generate or remove, respectively, a locking of the lens (3) on the frame (2) between said upper element (8) and lower element (9).
