BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a hinge assembly for an eyeglass frame, and more particularly, to a hinge assembly for an eyeglass frame that combines legs at both ends of a front hinge structure to realize folding and unfolding of legs.

In a typical eyeglass frame, a hinge assembly having a folding function is provided on both sides of the frame, and a leg is connected to the hinge assembly, so that folding between the leg and the frame is realized through folding of the hinge assembly.

The hinge assembly generally comprises a pair of hinge members mounted axially, wherein one of the hinge assemblies is fixed to the frame by welding, and the other hinge assembly is fastened or welded to the glasses frame Lt; / RTI >

Conventional spectacle frames have a frame and a hinge structure through welding or fastening of legs, so that it is difficult for ordinary people to separate them easily. Also, even for experts, it is required to use only a driver for repairing and replacing eyeglass frames and legs.

Particularly, the welded portion formed between the hinge assembly and the frame or the hinge assembly and the legs and the surrounding portion thereof are inevitably subject to thermal deformation, so that physical deformation may occur due to repeated use, and the welded portion may be damaged.

On the other hand, in Korean Patent Registration No. 10-0892543, there is provided an eyeglass frame having one eyeglass leg on each of left and right sides and respective connecting members on the left and right sides,

The end of the connecting member indicates the direction of the opened eyeglass legs and the joint members disposed on the connecting member are engaged with the joint member disposed at the end of the eyeglass leg to form a swivel joint, Wherein the fingers of the eyeglasses legs have three fingers at the ends of the eyeglass legs and the fingers have spring elasticity in the direction of the joint axis of the joints to hold the joint members in a rotatable manner, Wherein the leaf surface is constituted by plate springs which are substantially coplanar with the respective connecting members when the glasses legs are unfolded.

Accordingly, the fingers formed at the upper and lower portions of the three fingers form an outer leaf spring, and the fingers formed therebetween form a mid-leaf spring, so that the folding and unfolding of the leg is achieved by the mid- do.

Such a hinge assembly realizes a flexible folding and unfolding of the legs, thereby performing a critical function of preventing the legs from being arbitrarily developed or folded during the wearing or storing process.

Meanwhile, in the hinge assembly, the upper finger and the lower finger function to connect the connecting member in a hinge structure, and the fingers formed at the center implement the folding and unfolding of the leg assembled with the hinge structure.

In the hinge assembly, the upper finger, the lower finger, and the center finger are formed by cutting the legs in the longitudinal direction. In order to have a sufficient binding force due to the constraint of the folded legs, .

For example, when the central finger does not have sufficient elastic force, it is difficult to maintain the folded state of the leg. To increase the leg area or to increase the thickness of the leg, there are restrictions on the design, The problem may be degraded.

In addition, when the central finger is damaged, it is required to replace the entire leg. Therefore, it is not preferable from the maintenance standpoint and it is difficult to adjust the binding force of the leg by the central finger.

In addition, since the legs are hinged to the connecting member through the upper finger having a free end and the lower finger having a free end, the connecting portion between the leg and the hinge member when worn by the twist of the upper finger and the lower finger It is warped, and it is difficult to secure stable wearability.
