Spectacles, have U-shaped elastically deformable strip comprising branch immobilized by screw on flange and another branch that is freely supported on end forming branch cam and interposed perpendicularly between ends of branches of plates

摘要

The spectacles have an optical/solar frontage supported by side branches (3), each being connected directly to the frontage and a hinge. A U-shaped elastically deformable strip (8) of the branch is enclosed perpendicularly between parallel plates (9, 10) forming a flange. The strip has a branch (11) immobilized by a retaining unit (13) i.e. screw, on the flange and another branch (12) i.e. active branch. The latter branch is freely supported on an end (3a) forming a cam of the branch near a hinge axis (7) and interposed perpendicularly between ends of the branches of the plates.
