Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eyeglass frame connecting structure, and more particularly, to an eyeglass frame connecting structure that can be extremely easily assembled.

[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 a predetermined interval, a rod-like bridge spanned between the inner ends of both frames, a tongue attached to an outer end of each frame, and a pivotally attached to each tongue. Products with temples and the like are provided on the market.

In this eyeglass frame, the lens can be fixed to the inner part of each frame by positioning the lens inside the respective frame and tightening it with screws or the like so as to reduce the diameter of each frame. , So-called glasses.

However, in such a conventional eyeglass frame, a frame, a bridge, a chin, and a temple are separately formed, and the bridge is connected by welding between inner ends of both frames during an assembling process. The wisdom is connected to the outer end of each frame by welding, and temples are attached to each wisdom via hinges.Because there are many assembled parts when assembling the eyeglass frame, it takes time to process each part In addition, since welding is required at the time of assembling, the assembling work is also troublesome. In addition, poor welding is likely to occur during assembly, making it difficult to provide products of a certain quality.

[0005] Also, recently, an upper half made of one linear member and a lower half made of one linear member are combined to form a pair of annular frame portions and two frame portions. A bar-shaped bridge portion located between the ends and a mounting portion located at the outer end of each frame portion are formed, and the upper half and the lower half are formed separately from the upper half by the wisdom. There has been proposed an eyeglass frame connecting structure in which the mounting portions of the half and the lower half are connected. The tongue used here is formed separately from the upper half and the lower half as described above, and has a main body having a groove for fitting the mounting portion, and an opening in the groove. The main body has a screw hole, and the cover has a screw insertion hole.

In this eyeglass frame connecting structure, screw insertion holes are provided in each of the upper half and lower half mounting portions, and the upper half and the lower half are inserted into the grooves in the body of the body.

The upper and lower mounting portions are fixed in the grooves of the body of the torso, and the upper and lower mounting portions are simultaneously attached to the mounting portions of the torso.

However, in this eyeglass frame connecting structure, as described above, the tongue is composed of the main body and the lid, and is formed separately from the upper half and the lower half. When assembling the eyeglass frame, the upper and lower half mounting parts are fitted into the Ji's groove, and the lid is further fitted into the opening in the Ji's groove. Align the screw holes of the mounting part of the half and the lower part with the screw holes of the main part, and insert the screws through the screw holes of the lid and the screw holes of the mounting parts of the upper and lower parts. An assembly procedure such as screwing into a screw hole of the above and tightening with a predetermined torque must be taken.

[0008] As described above, in the above-mentioned conventional eyeglass frame connection structure, since the upper and lower halves have separate wisdoms and a large number of assembling parts, the assembling operation is large. It becomes complicated, and it is not possible to expect a significant improvement in production efficiency.

The present invention has been made in view of the above problems and has been made to solve the problems. The object of the present invention is to reduce the number of parts to be assembled, to assemble extremely easily, and to greatly improve production efficiency.
