Problems solved by technology

However, in the conventional eyeglass frames, because the materials of the entire bridge of the nose and the entire temples are made of superelastic materials, there is a problem that it is difficult to firmly wear them on the user's head.
That is, since the material deforms softly, the frame of the glasses worn will slide forward over time
In addition, when a large force is unintentionally applied when the spectacle frame is taken off, or in the case of an unexpected collision accident, etc., the spectacle frame is often deformed.

Abstract

Provided is a spectacle frame that employs shape-memorizing material to obtain wearing comfort and can be firmly worn without sliding forward. The spectacle frame (10) connects the left and right lenses (40) via the bridge of the user nose. A hinge (60) is utilized to install the spectacle legs, with the spectacle legs (50) capable of freely rotating. One side of the hinge (60) is provided with a clamping portion (66) clamped with a through hole arranged in the lenses (40), with the other side of the hinge (60) being provided with a hinge side fixing portion that is provided with an inserting hole. The spectacle legs (50) are provided with a spectacle leg side fixing portion, with the hinge (60) thereof having an inserting hole.

Description

technical field [0001] The present invention relates to a spectacle frame, and more particularly to a metal or resin spectacle frame that uses a superelastic material such as a shape memory alloy to achieve a comfortable wearing feeling. [0002] In addition, in this specification, the term "glass frame" means the structure which removed the part of "lens" from the whole "glasses." Background technique [0003] A typical spectacle frame has temples connected by hinges to both end portions of a front portion having a pair of lenses. In a full-rim type spectacle frame with a circular frame on the front or a half-rim type spectacle frame with a semi-circular frame, the left and right frames are connected in the center by a nose bridge, studs are provided at the ends of the two frames, and the temples are hinged. Connect with each pile head. [0004] In addition, in a two-point spectacle frame without a frame, the left and right lenses are directly connected at the center by t...
