Embodiment Construction

[0037] Figures 1A to 1G A hinge is shown comprising a hinge element 10 attached to a side piece 70 and joined to a lug 80 by an axis 90 of the hinge. The lug 80 is integrally formed with, or is formed partly by, the edge of the eyeglass frame (not shown). The lugs can also be screwed onto the lens, in this case into the edge of the frame.

[0038] The hinge element 10 comprises a box 20, a slide 30 and a spring 40, here a helical spring and serving to return the slide to its rest position.

[0039] The cassette 20 comprises a longitudinal housing 21, the front of which comprises or forms a guide area 22 of non-circular (for example rectangular) cross-section. The slider 30 comprises a hinge 31 extending to the outside of the housing, a guide portion 32 cooperating with the guide area 22 and a pin 33 extending to the rear of the housing 21 . The spring 40 is mounted on the pin 33 and sandwiched between a rear stop 50 integral with the pin 33 and a front stop 60 locked in tr...

Abstract

The element (10) has a slide (30) arranged in a longitudinal housing (21) along a longitudinal translation axis, and a slide return spring (40) assembled between a rear stop (50) and a front stop (60) i.e. ring. The spring has a compressibility that is sufficient for a guided part (32) to be removed from a rectangular sectioned guiding area (22). The slide pivots around its longitudinal axis when the part is removed from the area, in a manner to remain the slide in an out-blocked position for facilitating assembling / disassembling operations of a knuckle (31) with a hook shaped lug (80). Independent claims are also included for the following: (1) a spectacle frame comprising an elastic hinge element (2) a method of assembling and disassembling a hinge of a spectacle frame.

Description

technical field [0001] The present invention relates to the field of spectacles and hinges for spectacle frames, in particular in the application WO2005 / 121873 in the name of the applicant Figure 1A Or elastic hinge elements for spectacle frames of the type shown in 2. Background technique [0002] Such a hinge element comprises a slide in the housing and a return spring of the slide. The slider comprises a guide portion cooperating with the guide area of ​​the housing and an end forming a hinge extending to the outside of the housing. The spring works in compression between a rear stop and a front stop integral with the slider. [0003] The hinge elements are assembled at the factory before being attached to the spectacle frame. Once this assembly is complete, the slide has only a short path, making the installation or removal of the hinge more difficult, especially for the hinge, since the slide must be pushed against the return force exerted by the spring, and at the s...
