Description

{Hinge structure of eyeglass frames and legs}

The present invention relates to a hinge structure connecting a spectacle frame and a leg, and more specifically, to a hinge structure of an spectacle frame and a leg, which improves the hinge structure connecting the spectacle frame and the leg, thereby simplifying the structure, reducing the manufacturing cost by not relying on welding, improving the manufacturability and operability, and at the same time, has a firm bonding force and is easy to assemble and replace, thereby simplifying repairs, and pursues overall weight reduction while not exposing the joining part, thereby improving the aesthetics and wearing comfort, and allows the user to replace the leg with one of various colors, as needed, thereby pursuing various fashion styles.

Typically, glasses are made up of a frame and a leg, and the leg is connected to the frame through a hinge (or lining). These glasses have a structure where the lining is inserted between the frame and the leg, and each is firmly connected by welding, but recently, glasses that have adopted a partially connected structure have appeared, attempting to improve the assembly and enable changes in fashion.

As prior art documents that can be referenced in this regard, the following are presented: Republic of Korea Utility Model Registration No. 20-0315936 (prior document 1), Republic of Korea Utility Model Registration No. 20-0415626 (prior document 2), and Korean Patent Publication No. 10-2013-0057124 (prior document 3).

Prior art document 1 proposes a glasses (1) in which a lens fixing member (9)(10) to which a bolt (11) is fastened so that a lens (3) can be replaced is welded to a hinge member (5) connected to a glasses frame (4) that is folded by a hinge (6)(7) fastened to a bolt (8) on the lens fixing member (10); a replacement structure of a glasses frame and a hinge member including a hinge member is proposed in which a fixing member holder (12) formed at the tip of an “ㄱ” shaped hinge member (5) connected to the glasses frame (4) has a fastening hole (13) so that a lens fixing member (9)(10) formed on the glasses frame (2) can be inserted and removed.

However, according to the above-mentioned prior art, since the eyeglass frame (2) has various thicknesses, a hinge part (5) that matches it must be produced, which increases the manufacturing cost, and since it uses a hinge part (5) in the shape of the letter “ㄱ”, it is difficult to manufacture, so productivity and workability are significantly reduced, resulting in a high manufacturing cost.

Prior art document 2 proposes a spectacles bridge connecting device that is composed of a connecting body (11) fixed to a spectacle frame (1), a square-shaped rotating body (12) fixed to an end of a spectacles bridge (2), and a hinge (13) that rotatably connects the connecting body (11) and the rotating body (12), thereby facilitating assembly work and reducing assembly time and manufacturing costs.

However, according to the above-mentioned prior art, there is a disadvantage in that the bonding strength of the part connecting the legs to the hinge is weak, so there is a great risk of injury to the glasses wearer even with a small impact.

Prior art document 3 proposes a connecting structure between an eyeglass frame and an eyeglass frame, characterized by comprising: a hinge piece (12) formed by protruding on the inside of an end piece (11) integrally formed at the end of an eyeglass frame (10) by synthetic resin injection and having a catch groove (a); an elastic member (20) having an upper plate and a lower plate each formed with a catch hole (b) that is elastically bent in the middle so as to be fitted into the hinge piece (12) in a double manner, and a protruding portion (21) formed laterally in the middle of the upper plate by being bent at a predetermined angle; and an eyeglass frame (30) having a rotary pin (31) formed at the tip so as to be fitted into the catch groove (a) of the hinge piece (12) while elastically pressing the upper plate of the elastic member (20), and an operating hole (c) formed relatively long in the longitudinal direction at the tip so as to be able to rotate around the rotary pin (12).

However, according to the above-mentioned prior art, this also adopts a configuration in which both ends of the metal eyeglass frame are bent and connected to the eyeglass arms, which causes a problem in that repair due to breakage or impact is almost impossible.
