Abstract

La présente invention vise à proposer une monture de lunettes de type à charnière ajustée avec laquelle il est possible de réaliser une monture plus légère, sans préoccupation à propos d'une charge significative qui est appliquée dans une direction de torsion sur les cercles ou les lentilles même si un verrou de cercle n'est pas présent, et de plus, est facile à fabriquer et a un degré de liberté élevé dans une conception de monture. A cet effet, la présente invention porte sur une monture de lunettes formée à partir d'une plaque métallique mince et configurée pour comprendre une monture (1) comprenant en outre une pièce d'extrémité divisée (B-B) qui est divisée verticalement en deux pièces ; et des branches (2-2) qui sont couplées par charnière à la pièce d'extrémité divisée (B) de la monture (1). Une pièce de charnière femelle côté supérieur (13a) et une pièce de charnière femelle côté inférieur (13a') sont formées en alignement dans des parties de maintien verticales (13-13) de la pièce d'extrémité divisée (B), et des parties latérales extérieures (P-P') et des parties latérales intérieures (Q-Q') sont respectivement formées dans chacune des pièces de charnière femelles (13a-13a'). Inversement, le positionnement d'une face d'extrémité de base de la branche (2) dans une position de butée contre les parties latérales intérieures (Q-Q') des pièces de charnière femelles (13-13') lorsque la branche (2) est ouverte vers l'extérieur permet de contraindre l'ouverture vers l'extérieur de la branche (2) par les parties latérales intérieures (Q-Q').
