Abstract
An elastic hinge member (10) for spectacles rims, includes a guiding area (22), a slide (30) having a guided part (32) cooperating with the guiding area (22) and a knuckle (31) and a return spring (40). The spring (40) has a compressibility that is sufficient for allowing the guided part (32) to come out of the guiding area (22), and the slide (30) can pivot about the longitudinal axis thereof in order to remain blocked in an “out-blocked” position that facilitates the assembling or disassembling operations of the knuckle with a spigot

Elastic hinge element (10, 110, 210) for eyeglass frames, comprising:
- a longitudinal housing (21) comprising a guide zone (22),
- a slide (30, 130, 230) arranged in the housing along one longitudinal axis of translation, the slide comprising a rear part (33) with one end (50) arranged in the housing (21), a guided part (32, 132) that works with the guide zone, and a knuckle (31, 131, 231) extending to outside the housing, and
- a return spring (40) of the slide mounted between a rear stop (50) and a front stop (60),
- characterized in that the spring (40) has compressibility that is sufficient to allow the guided part (32, 132) of the slide to leave the guide zone (22),
- and in that the slide (30, 130, 230) can pivot around its longitudinal axis when the guided part (32, 132) has left the guide zone so as to move the slide into a “locked-out” position that makes an operation of assembly or an operation of disassembly of the knuckle with a lug (80, 180, 280) easier.
Process of mounting or dismounting a hinge of an eyeglass frame comprising an elastic hinge element (10, 110, 210) and a lug (80, 180, 280), the hinge element comprising:
- a longitudinal housing (21) comprising a guide zone (22),
- a slide (30, 130, 230) arranged in the housing (21) along one longitudinal axis of translation, the slide comprising a rear part (33) with one end (50) arranged in the housing (21), a guided part (32, 132) that works with the guide zone (22) and a knuckle (31, 131, 231) extending to outside the housing, and
- a return spring (40) mounted between a rear stop (50) and a front stop (60),
- characterized in that it comprises stages consisting in:
- imparting to the return spring (40) a compressibility that is sufficient to allow the guided part (32, 132) of the slide (30, 130, 230) to leave the guide zone,
- moving the guided part (32, 132) outside of the guide zone (22),
- causing the slide (30, 130, 230) to pivot around its longitudinal axis so that it remains locked in a “locked-out” position, and
- assembling or disassembling the knuckle (31, 131) and the lug (80, 180, 280).
