<p>The invention concerns an elastic hinge for spectacles comprising on the first side (6), a male knuckle (10) and on the second side (4) a female knuckle (20) coupled with the male knuckle by a linking pin (12). When the male knuckle periphery (10') on the first side (6) is in the form of a cam (13, 15), the orifice (11) for the passage of the male knuckle (10') linking pin (12) is then in the form of a longitudinal slot (16) oriented towards the cam-shaped periphery (13, 15). A spring (18) housed in the slot (16) acts between said slot bottom and the linking pin (12) to push the male knuckle cam-shaped periphery against the female knuckle (20') end. When the periphery of the female knuckle (20) aperture rings is in the form of a cam, the first side (6) flat end (14) has then, a transverse longitudinal slot (16). An external part (30) comprising an internal projection (34) slides against the first side (6) flat end (14) wide surfaces covering the slot (16) on either side.</p> |
