[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eyeglass frame, and more particularly to an eyeglass frame with high production efficiency.

[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.

A plastic or glass lens is positioned between the upper frame 3 and the lower frame 7, and the outer connecting member 13 is held in a state where the upper mounting portion 5 and the lower mounting portion 9 are in close contact with each other. The lid 16 is attached to the main body 14 and the opening of the groove 15 is closed.

A screw 17 is located on the lid 16 side,
The screw part is screwed into the screw hole 14a of the main body part 14 through the screw insertion hole 16a of the lid part 16, the screw insertion hole 9a of the lower attachment part 9, and the screw insertion hole 5a of the upper attachment part 5. And tighten them with a predetermined torque.

A holding member 19 is flexibly attached to a hinge 18 located at a tip of the outer connecting member 13, and a synthetic resin ear pad 20 is attached to the bent end of the holding member 19. Is mounted, and in this manner, the glasses frame 1 according to this embodiment, which includes a plurality of members, is integrally assembled.

In the eyeglass frame 1 according to this embodiment configured as described above, the material of the upper half 2 and the material of the lower half 6 are fitted into the fitting portions 11 of the inner connecting member 10. Then, the two materials are bent by using a machine such as a press, so that the upper half 2, the lower bridge 8, the lower frame 7, and the lower mounting part comprising the upper bridge part 4, the upper frame part 3, and the upper mounting part 5. 9 and the outer connecting member 13 is mounted on each of the upper mounting portion 5 and the lower mounting portion 9, and the upper mounting portion 5 and the lower mounting portion 9 are integrally formed by the outer connecting member 13. Since the two halves 2 and 6 are assembled, no welding work is required.

Accordingly, since the number of welding points as a whole can be reduced, the labor required for assembling can be greatly reduced, and the production efficiency can be greatly improved. In addition, since the number of welding points is small, the quality of the product is not affected by the experience and intuition of the worker, and a product of good quality can always be provided.

In the above description, the outer connecting member 13 is composed of the main body 14 and the lid 16, but the outer connecting member 13 may be formed integrally with the main body 14 and the lid 16. It is a good thing, and it is good also as what is an existing shape, such as a cylinder, an animal, a plant, and a building, as an outside connection member, and what is necessary is just a shape which can fix both attachment parts 5 and 9. It is.

[0026]

According to the present invention, as described above, the upper half and the lower half are each made of a single metal rod-shaped material by bending using a machine such as a press. Along with being able to be formed, the upper bridge part of the upper half and the lower bridge part of the lower half are connected by the inner connecting member,
The upper attachment portion of the upper half and the lower attachment portion of the lower half can be integrally connected by the outer connection member. Therefore, no welding work is required to assemble the upper half portion and the lower half portion, so that the number of welding portions as a whole can be significantly reduced. Therefore, the labor required for assembling can be significantly reduced, and the production efficiency can be greatly improved. Further, since the number of welding points can be reduced, excellent effects such as always providing a good quality product can be provided without depending on the experience and intuition of the worker.
