Description

[Detailed description of the invention] [Industrial application field] The present invention is an improvement of the eyeglass hinge. Specifically, by making the hinge spherical, the folded part of the eyeglass hinge is improved not only during use but also when the temple is bent. This relates to a spherical hinge structure that is not angular and has a sophisticated appearance.

[Prior art and problems to be solved]

As is well known, the temples of glasses, whether made of metal or plastic, have a flat cross-section and are connected to a bracket fixed to the outside of the rim using a screw. . therefore,
When the temple is expanded, the end of the bracket and the tip of the temple are butted against each other, but when not in use, the temple is folded, so both end surfaces open at approximately 90 degrees, with the tip of the temple facing outward. This had the disadvantage of being exposed and getting caught in clothing, etc., causing it to tear.

The present invention eliminates the above-mentioned drawbacks of conventional eyeglass screws, and goes one step further to create a new structure of eyeglass screws that can add a one-point design feature to the eyeglass screw portion, which tends to flow monotonously. This is an attempt to provide a number.

[Means adopted to solve the problem]

The means adopted by the present invention to solve the above problems will be explained below with reference to the accompanying drawings.

That is, the eyeglass screw provided by the present invention has a rim frame 1.
A spherical part 3 is provided at the end of the bracket 2 fixed to the outer side of the bracket 2, and a slit 4 of a constant width is formed along the lateral great circle line of the spherical part 3.
Inside, a stopper 5 is provided at a position close to the bracket 2, a screw hole 6 is provided at the lower hemisphere pole of the spherical portion 3, and a sunken hole 8 with a seat hole 7 is provided at the upper hemisphere pole, On the other hand, Temple 10
A disc-shaped flange portion 11 having approximately the same diameter as the spherical portion 3 and fitting into the slit 4 is provided at the end thereof,
A shaft hole 12 having the same diameter as the sunken hole 8 is provided at the center of the flange portion 11, and a small diameter portion 13 is provided on the outer periphery of the flange portion 11 at a width of approximately 90° inward from the tip, into which the stopper 5 slides; The flange portion 11 at the tip of the temple is assembled into the slit 4 of the spherical portion 3, the hinge shaft 14 is inserted from above the sink hole 8, and the hinge shaft 14 is tightened and fixed so that its head sinks into the seat hole 7.

Therefore, when wearing glasses, as shown in FIG.
On the other hand, when the temple 10 is bent, the stopper 5 comes into contact with the other step of the small diameter portion 13 and is positioned.

[Effects of this invention]

The glasses of this invention have a combination structure of a spherical support hinge piece and a disc-shaped structure as described above, so the appearance is spherical in all directions without any protrusions or angular parts, so it does not touch clothes etc. There is no danger of it getting caught, and the spherical shape creates a one-point change in the otherwise monotonous side shape of the glasses, making it an interesting design.

Also, from a structural point of view, the contact area between the slit 4 and the flange portion 11 is large, and the structure is stable and has little wobbling, so it is strong in terms of strength.

As described above, the present invention provides benefits that cannot be expected from conventional eyeglass hinges, both in terms of practicality and design.
