Abstract

L'invention concerne une monture articulée pour lunettes possédant une excellente durabilité. Ladite monture comprend un cadre avant pouvant tourner en douceur et facilement maintenu à un angle de rotation arbitraire, et une paire de cadres avant qui ne se superposent pas vers l'arrière et vers l'avant comme les lunettes articulées classiques. Lorsqu'on tourne le cadre avant principal et qu'on le relève devant les yeux, un arbre rotatif (11) relié audit cadre avant principal tourne tout en s'opposant à la résistance de frottement entre un tube en résine (14), une barre en pont et la résilience d'un ressort à lames. Lorsqu'on atteint un angle désiré, on arrête de tourner le cadre avant principal et le tube en résine (14), et l'arbre rotatif (11) est soumis à la résistance par frottement entre le tube en résine (14), la barre en pont (10) et la résilience du ressort à lames (13) et maintenu à cette position.
