摘要:
The invention is concerned with a new constructive form of hinge for junction and opening of the arms (A) on the front (F) of the glasses, and being the automatic closure of the arms (A), when the glasses aren't being worn. The innovative peculiarity of the invention is to provide the presence of an elastic means (6), operating on a pin (26) of a gear (27), arranged in direct grip with a crown wheel section (11) of a disk (10), where it determines and regulates the movement of the gear (27), the gear (27) itself being solid to the arm (A) to open, whereas the crown wheel section (11) is fixed with the extremity of the hinge of front (F) of glasses.
摘要:
The present invention concerns a hinge for the hinging of spectacle temples, which allows the automatic closing of the temples on the same front of spectacle which has been removed from the head or which features one or both temples in open or wide-open position. A hinging element is provided attached to the endpiece of the front, which is cam-shaped with an eccentric profile progressively increasing from its internal position to its external position and on which a follower runs. The follower is guided in an axial hole 23 in the temple 20 to be hinged and together with an elastic medium which acts axially with the hinge pin while the follower works on an inclined plane produced by the shape of the cam to help the automatic return of the temple 20 in the closing phase.
