Problems solved by technology

However, this hinge has two spacers in addition to the outer hinge body and the inner hinge body, so there is a problem that the number of parts increases, the overall structure is complicated, and it is easy to cause failure. Or, in order to make the hinge strong and avoid failure, there is The problem of having to make the hinge bigger overall

Embodiment Construction

[0036] Figure 1A ~ Figure 3D An example of the hinge for glasses of the present invention is shown. Figure 1A ~ 1C It is a state in which the first link 20 , the second link 30 , and the shaft member 40 constituting the hinge 10 for eyeglasses are assembled, and shows a state in which the temples of the glasses are opened to the maximum. The first link 20 is a link connected to the front of the glasses, and the second link 30 is a link connected to the arms of the glasses. Here, the first connecting member 20 is used as the outer connecting member, and the second connecting member 30 is used as the intermediate connecting member, and they can also be exchanged.

[0037] The first connecting member 20 has: a pair of central portions 21a, 21b formed in a small annular shape; a pair of outer peripheral portions 22a, 22b formed as part of a larger annular body than the pair of central portions 21a, 21b; Part 23, which is connected to the front part. The pair of central parts 2...

Abstract

The invention provides a glass hinge which has a small and simple structure without failure. A glass, which has comfortable wearing sense and can be stably worn at the head of a user without falling off forwardly, is provided. The glass hinge comprises a first connecting piece (20) connected to a front face part, a second connecting piece (30) connected to glass legs, and a shaft component (40) connected to the two connecting pieces. The first connecting piece (20) and / or the second connecting piece (30) are / is provided with an elastic part which is made from super-elastic materials and can be deformed. The first connecting piece (20) and the second connecting piece (30) are respectively provided with the elastic part. The two elastic parts respectively form a part of a ring-shaped body having equal outer diameter.

Description

technical field [0001] The present invention relates to a hinge for spectacles, and in particular, relates to a hinge for spectacles that can make the wearing of the spectacles comfortable and securely wear the spectacles on the head of the user. Moreover, it is related with the spectacles using this hinge for spectacles. Background technique [0002] Two techniques can be cited as main methods for making glasses comfortable to wear. One approach is the technique of using hyperelastic materials. For example, Patent Document 1 describes the invention of using a Ni, Ti, Co ternary superelastic material and a Ni, Ti binary superelastic material for the bridge of the nose and the temples of the glasses. Research on shape memory heat treatment. Patent Document 2 describes an invention related to a synthetic resin material for a front mirror frame, wherein a polyamide-based superelastic resin is used as the synthetic resin material. [0003] Spectacle frames using superelastic...
