Connection hinge for spectacles frames of the type adapted to connect the lateral sidearm of a spectacles frame to the front part of the same spectacles frame; the connection hinge being characterized by comprising: a cup-shaped body, which is structured so as to be fixed cantilevered in a rigid manner onto the lateral side of the front part of a spectacles frame, and is provided with a central cavity of substantially cylindrical shape and with a transversal, oblong, pass-through slot or cut, which extends along the lateral side of the cup-shaped body while remaining on a lying plane locally substantially perpendicular to the reference axis of the central cavity, and penetrates in the cup-shaped body up to said central recess; a central pin which has a cylindrical shape substantially complementary to that of the central cavity of the cup-shaped body, and is inserted in axially rotatable manner in the central cavity of the cup-shaped body; and a transverse locking plug which has an end rigidly fixed to the body of the central pin, and is structured so as to protrude cantilevered from the cup-shaped body engaging in pass-through and sliding manner the pass-through slot or cut present on the lateral side of the cup-shaped body, and to be rigidly fixed or incorporated on the proximal end of the lateral sidearm of the spectacles. |

1. Connection hinge (1) for spectacles frames (100) of the type designed to connect the lateral sidearm (102) of a spectacles frame (100) to the front part (101) of the same spectacles frame (100); the connection hinge (1) being characterized by comprising:
a cup-shaped body (2) which is structured so as to be fixed cantilevered and in rigid manner onto the lateral side of the front part (101) of a spectacles frame (100), and is provided with a substantially cylindrical-shaped central cavity (3) and with a transversal, oblong, pass-through slot or cut (5) which extends along the lateral side of the cup-shaped body (2) while remaining on a lying plane locally substantially perpendicular to the reference axis (C) of the central cavity (3), and penetrates in the cup-shaped body (2) to reach said central cavity (3); a central pin (4), which has a cylindrical shape substantially complementary to that of the central cavity (3) of the cup-shaped body (2), and is inserted in axially rotatable manner in the central cavity (3) of the cup-shaped body (2); and a transversal locking plug (6) which has an end (6a) rigidly fixed to the body of the central pin (4), and is structured so as to cantilevered protrude from the cup-shaped body (2) engaging in pass-through and sliding manner the pass-through slot or cut (5) present on the lateral side of the cup-shaped body (2), and so as to be rigidly fixed to or incorporated on the proximal end of the lateral sidearm (102) of the spectacles. |
