<p>The glasses (1) have an optical or solar frontage (2) supported by branches (3), where each branch is connected to a mounting (4) or directly to the frontage by a tenon (5) and an articulation (6). The branch has a clamp (8) whose parallel arms (9, 10) enclose upper and lower fields of a rigid element, where the clamp is in U-shape. The clamp and the element are secured to articulation of the tenon and end heel (13) of the branch, respectively and retained relative to each other by a locking unit (7) in three directions at 90 degree based on height (h), length (L) and thickness.</p> |
