Glasses, have clamp and rigid element that are secured to articulation of tenon and end heel of branch, respectively and retained relative to each other by locking unit in directions at specific degree based on height, length and thickness

摘要

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.
