Spectacles i.e. rimmed glasses, have lug with male and female parts comprising bends emerging from virtual center corresponding to axis of branch relative to case front such that parts slide in rotation to form screwless articulation

摘要

The spectacles have an optical or solar case front (2) with two branches (4), where each branch is connected to a frame (3) or case front by a lug (5) and a damper element (6). The lug has a male part (5A) integrated to the case front or frame, and a female part (5B) integrated to an end of the branch. The parts have bends (C, C') emerging from a virtual center (O) corresponding to an articulation axis of the branch relative to the case front such that the parts slide in rotation around the axis by interpenetration during roll out or roll back of the branch to form a screwless articulation.
