Embodiment Construction

[0066] Referring to the accompanying drawings, an elastic hinge 1 of a spectacle frame realized according to the present invention is completely shown.

[0067] According to the invention, the elastic hinge 1 is intended to realize any type of spectacle frame, including corrective spectacles, sunglasses, sports glasses or other types of spectacles, and is used in a known manner to be interconnected to a frame corresponding to the nose 3 of the spectacle frame. on leg 2.

[0068] The spectacle frame will be realized in a completely conventional form, therefore in a plastic material, such as nylon, acetate or another plastic material suitable for the purpose, or also in a metal material. The framework is not in a specifically required form, so its design principles are briefly described below to a skilled person.

[0069] In more detail, the frame generally consists of a front for supporting a pair of lenses connected in the middle by a bridge and a pair of legs 2 pivotally sec...

Abstract

Elastic hinge for spectacle frames, comprising a hinge screw (6) used in the holes of the two hinge elements (4, 5) to connect them. The hinge screw (6) comprises a shank (61) provided with a narrow portion (61A) for insertion into the hole (50A) of the first tab (5A) of the first hinge element (5), and an enlarged ring portion (61B) for forming a step (70) and inserting into the hole (90A) of the head (9A) of the other hinge element (4). The hinge screw (6) easily achieves a limit position (P1), where the screw is tightened and aligned with the hinge axis (X), and a locked position (P2), where the screw is loosened and is controlled by the hinge elastic device (7) The applied spring force is inclined relative to the hinge axis (X), in such a way that the step (70) of the hinge screw (60) meets the edge (71) of the hole (50A) of the first wing (5A) of the hinge element (5), This prevents further unscrewing of the articulation screw (6).

Description

technical field [0001] The invention relates to an elastic hinge for spectacle frames and a method for handling the hinge screws of the hinge. [0002] The elastic hinges in question are intended to be better used in the manufacture of plastic and metal eyeglass frames of any kind, especially for sunglasses and corrective eyeglasses. [0003] Therefore, the hinge according to the invention relates to the eyewear industry producing eyeglasses and their accessories and eyeglass components. Background technique [0004] In the eyewear industry, hinges are traditionally used to hinge the legs to the front of the frame. [0005] Each hinge usually consists of two hinge elements that pivot relative to each other, the first element being fixed to the leg and the second element being fixed to one of the side sections of the front of the frame (also referred to in the terminology of the art as for "nose"). [0006] Functionally, the hinge allows the legs to rotate between a closed...
