Abstract: Hinge mechanism for glasses, with terminations in lateral of the frontal, provided with receptions and flexible ends in trident in the temples with insertions, a coupling connector for mobile and flexible union that is assembled to the above mentioned terminations. The flexible terminations have a distal loop with a window with a trident insert. The trident of the flexible ends of the temples is composed of a central tab and two parallel extensions, upper and lower, turned ninety degrees, separated by intermediate spaces. The coupling connector has a lateral opening longitudinal for reception and insertion of the terminations, a transverse gap that coincides with the window suitable for receiving the central tab of the flexible ends of the temples.
