<p>The side-arm knuckle (20) of the elastic hinge for spectacles is prolonged by a slide (30) which can move in a housing (10,12) in an elastic manner against the action of a spring (40) lodged in a central longitudinal slot (34) in the slide and acting between a transverse stop (44) fastened to the housing and the rear end of the slide (32). This side-arm knuckle (20) and the slide (30) are made in two pieces of different material, and then assembled. The slide (30) is, especially, a tube of elongate rectangular cross-section and the knuckle (20) has a rear body (22) in which a slit (26) is made, designed to receive the lateral front end face of the slide. <IMAGE></p> |
