<p>A closing device for glasses orbit rim is described. The orbit is divided into two parts (6,7) for the arrangement of a lens (3). The closing device comprises two bushings (8, 9) each integral with the ends of the respective two parts (6,7) of the orbit (2) and a coupling device (11) for coupling the two bushings (8, 9). The coupling device (11) is made up of a non threaded screw (11) with an enlarged head (13) and with a stem (4) provided with T-10 shaped end (12). The two bushings (8,9) are provided with an internal axial slot (16) for the passage of the stem (4) and the T-shaped end (12) of the screw (11) and with a supporting surface (20) for said end (12) of the screw (11) when this is rotated from the position of insertion. The closing device comprises a ring (15) of elastic material arranged around the stem (4) of the screw (11) in proximity of the head (13) of the same screw in such a way as, to be squeezed between the head (13) of the screw (11) and the first one (9) of the two bushings (8,9) in the direction of insertion of the screw (11) into said slot (16) of the two bushings (8,9).</p> |
