Abstract

L'invention concerne un mécanisme d'articulation destiné à être monté entre l'extrémité temporale du verre et l'extrémité de la branche, d'une paire de lunettes à montures métalliques (ou percées), qui permet de rendre la partie temporale ou l'extrémité de la branche plus fines, et d'offrir un mécanisme d'articulation de structure simple. Ce mécanisme d'articulation est caractérisé par une structure permettant de retenir un anneau de pivotement dans un anneau de retenue, formé par superposition d'une pluralité de structures annulaires dont la circonférence interne entre sensiblement en contact avec la circonférence externe de l'anneau de pivotement, et l'assemblage/la rotation de ces anneaux. Ce mécanisme d'articulation de lunettes est en outre caractérisé en ce que l'anneau de retenue est formé par brasage d'une pluralité de anneaux sur l'extrémité d'une section des lunettes, et en ce que cette pluralité d'anneaux brasés sur l'extrémité d'une section des lunettes agit également comme mécanisme de butée à l'ouverture.
