Elastic hinge element for spectacles frame

An elastic hinge element for a glasses frame that comprises:

• a box (100, 110, 120) that comprises a guiding cavity (101),
• a slide (200) that comprises a body moving in the guiding cavity (101), and
• at least one elastic piece (204, 237, 241, 242, 271) that works with the box (100) to produce an elastic reaction that opposes the extraction of the slide from the guiding cavity (101),
• characterized in that the slide body (201, 221, 231) comprises an inside cavity that accommodates the elastic piece,
• and in that it comprises a holding clip (207) for locking a proximal end of the elastic piece relative to the box (100), with the holding clip comprising flexible arms that extend in a distal direction and holding means (207a, 207b) that work with the box (100).

A process for manufacturing an elastic hinge element for a glasses frame, whereby the hinge element comprises a box (100, 110, 120) that comprises a guiding cavity (101), a slide (200) that comprises a body that moves into the guiding cavity (101), and at least one elastic piece (204, 237, 241, 242, 271) that works with the box (100) to produce an elastic reaction that opposes the extraction of the slide from the guiding cavity (101), the process comprising:

• providing an inside cavity in the slide body (201, 221, 231),
• producing a holding clip (207) for locking a proximal end of the elastic piece relative to the box (100), whereby the holding clip comprises flexible arms that extend in a distal direction and holding means (207a, 207b) that work with the box (100),
• arranging the elastic piece in the inside cavity, and
• arranging the holding clip in the elastic hinge element.
