Abstract
The invention relates to an elastic hinge element (60) for a spectacle frame, comprising a body (10) consisting of a housing (11) comprising a guiding area (12) and at least one cavity comprising a retaining partition, a slide (20) fitted in the housing and comprising a guided part (22), a center part and a rod, a spring (40) for returning the slide to a rest position, mounted around the rod, and a bushing (30) forming a front stop for the spring. According to the invention, the cavity comprising the retaining partition is located in the guiding area (12) and opens out therein, and the guided part (22) of the slide comprises a recess into which an elastic tab (32) of the slide extends. Advantage: creation of a short-length hinge element.
Claims13
An elastic hinge element for a spectacle frame, comprising:
- a housing comprising a hollow longitudinal portion comprising a guiding area, the guiding area having at least one cavity defining a retaining wall,
- a slide arranged in the hollow portion according to a longitudinal translation axis, comprising a protruding part extending outside the hollow portion, a guided part cooperating with the guiding area, a central part and a rod,
- a spring for returning the slide to a rest position,
- a compression part for compressing the spring, coupled with the rod, forming a rear stop for the spring, and
- a bushing forming a front stop for the spring, comprising a body mounted around the central part of the slide and at least one elastic tab extending towards a front of the hollow portion according to a determined angle, a distal end of the at least one elastic tab presses on the retaining wall,
- wherein the cavity comprising the retaining wall opens out in the guiding area, and the guided part of the slide comprises at least one first guiding face that comprises:
- a recess into which a portion of the at least one elastic tab extends when the slide is in the rest position, and
- guiding edges situated along the recess, an entire length of the guiding edges being in contact with the guiding area of the hollow longitudinal portion of the housing in and between the rest position and an extended position of the slide.
An elastic hinge element for a spectacle frame, comprising:
- a housing having a hollow interior defining a guiding area, the guiding area having at least one cavity recessed into the housing to form a retaining wall;
- a slide positioned in the hollow interior, the slide including a protruding part located outside the guiding area, a guided part located within the guiding area and a rod having a rear stop;
- a spring positioned over the rod and abutting the rear stop;
- and
- a bushing mounted on the rod and positioned between the guided part and the spring, the bushing having at least one elastic tab extending toward a front of the hollow portion at a determined angle, a distal end of the at least one elastic tab abutting the retaining wall, wherein the guided part of the slide includes at least one first guiding face having a recess therein, the at least one elastic tab extending into the recess in a rest position, the recess forming at least one guiding edge proximate the recess, an entire length of the at least one guiding edge being in continuous sliding contact with the guiding area.
