[0002]

2. Description of the Related Art There are various types of eyeglass frames for eyeglasses used for correcting eyesight, protecting eyes from ultraviolet rays, and the like.
A pair of annular frames positioned at predetermined intervals, a bar-shaped bridge spanned between inner ends of both frames, an armor attached to an outer end of each frame, and a temple flexibly attached to each armor Glasses frames having a pair of legs attached to the inner end of each frame and a nose pad attached to the tip of each leg are provided on the market.

The lens is fixed to the inner part of each frame by positioning the lens on the inner part of each frame of the eyeglass frame having such a configuration and tightening the respective screws to reduce the diameter of each frame. So-called glasses are configured.

However, in the conventional eyeglass frame having the above structure, the bridge is connected at both ends by welding between the inner ends of both frames, and the armor and legs are also welded at one end to each frame. Are connected to the outer end and the inner end, so that the number of welding points as a whole increases, the assembling takes time, and the production efficiency deteriorates. In addition, the quality of welding largely depends on the experience and intuition of the operator, and it is difficult to always provide good quality.

The present invention solves the above-mentioned problems of the prior art, and can reduce the number of welding points as a whole and greatly reduce the labor required for assembly. It is an object of the present invention to provide a spectacle frame that can significantly improve production efficiency and always provide good quality without depending on an operator.
