Embodiment Construction

[0029] The elastic hinge 1 of the spectacle frame according to the present invention is shown as a whole with reference to the accompanying drawings.

[0030] According to the invention, the elastic hinge 1 is aimed at realizing various spectacle frames, both traditional and sporty, and is intended to be interconnected to a leg 2 corresponding to the nose 3 of the spectacle frame.

[0031] In more detail, the frame usually consists of a front for supporting a pair of lenses connected by a bridge in the middle through two annular sections (or "circles") and a pair of lenses pivotally secured to the sides of the front by elastic hinges 1 The legs 2 constitute, more precisely, the elastic hinges fastened to the two side parts towards the rear of the glasses, called noses 3 in the technical terminology of the industry.

[0032] In particular, the hinge 1 is elastic, which allows the legs 2 to open overtravel, and the elastic resilience makes the glasses comfortable to wear and ens...

Abstract

An elastic hinge for the plastic frame of eyeglasses comprises a first articulation element and a second articulation element, wherein the first articulation element comprises a box-like body provided with a seat and a carriage provided with a rod-like element inserted in the seat and with a head externally projecting from the seat and coupled with the second articulation element. A bush is slidably mounted on the rod-like element, and a spring thrustingly acts on such bush. A fork-shaped body is inserted from the outside into a hole of the box-like body and is engaged with the bush in a straddling manner in order to retain the latter with respect to sliding along the longitudinal axis of the rod-like element.

Description

technical field [0001] According to the preambles of the respective independent claims, the invention relates to an elastic hinge for spectacles and a method of assembling said elastic hinge. [0002] The hinge in question is designed to optimize eyeglass production, in particular its assembly method is easy to use during the production of eyeglasses, mechanically connecting the legs to the nose. [0003] Therefore, this hinge and its method of assembly relate to the eyewear industry producing eyeglasses and eyewear accessories and eyewear components. Background technique [0004] As is well known in the eyewear industry, hinges are used to hinge the legs to the front of the frame. [0005] Each hinge is traditionally made up of two hinged elements pivoting relative to each other, the first element being fixed to a leg and the second being fixed to a side section (in the terminology of the art) of the front of the frame, respectively. Also known as the "nose"). [0006] F...
