Abstract
An elastic hinge (40), in particular for spectacle frames, has first and second hinge elements (50, 60) rotatably mounted around a pivot (45), a cam profile (53) integral with the first hinge element, a bearing piece (65) movably mounted in the second hinge element along an elastic translation axis. The bearing piece has a first contact area co-operating with the cam profile to give the hinge at least one stable position, and provides a lock for the hinge when a position of excessive opening is reached. The lock includes a protrusion (53-4) of the cam profile arranged for co-operating with a second contact area (65-2) of the bearing piece by exerting, essentially on the bearing piece, a force substantially perpendicular to the translation axis thereof.

An elastic hinge, comprising:
- first and second hinge elements rotatably mounted around a pivot,
- a cam profile integral with the first hinge element,
- a bearing piece movably mounted in the second hinge element along an elastic translation axis, having a first contact area for co-operating elastically with the cam profile and for giving the hinge at least one stable position, and
- a lock for the hinge when a position of excessive opening is reached,
- wherein the lock for the hinge comprises a protrusion of the cam profile arranged for co-operating with a second contact area of the bearing piece by exerting, essentially on the bearing piece, a force perpendicular to an elastic translation axis of the bearing piece, the protrusion of the cam profile forming with the second contact area of the bearing piece a stop against excessive opening.
