BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a modern incorporating a plastically deformable metal pipe, and an eyeglass temple using the same, and more specifically, inserting a metal core of the temple deep inside the modern incorporating the metal pipe. The shape of the temple can be easily adjusted by hand bending to suit the wearer's wearing, and the length of the entire temple can be changed by changing the depth at which the metal core of the temple is inserted. The present invention relates to a spectacle component that can be adjusted to a required size and, if necessary, can display a beautiful decorative pattern on a modern surface and inside.

As is well known, as modern glasses,
A type in which a metal core at the free end of the temple is coated with a synthetic resin material is widely used. By the way, in this type of modern, a plastically deformable metal material is used as a core material, and by inserting this core material deep into the synthetic resin material, the entire modernity can be plastically deformed, and the wearer's ear The bending of the modern is adjusted according to the shape of the hanging part.

However, in the above-mentioned modern, since the temple core material needs to be inserted up to the vicinity of the end of the synthetic resin material, the length of the temple becomes long, resulting in an increase in raw material cost. . In particular, when a temple made of an expensive material such as a solid gold material is used, the manufacturing cost greatly varies depending on the length of the temple, which is directly reflected in the price of the spectacles.

In addition, in such a conventional modern, when it is bent to match the shape of the ear hook of the wearer, the bending position of the modern is changed to adjust the apparent length of the entire temple to some extent. Although it is possible, there is a limit to the adjustment range, and it would be a problem if the left and right temples were disproportionate in appearance. Therefore, if the length of the temples on the wearer's face exceeds this adjustable range, even if the spectacles of your favorite design, replace the temples or choose other spectacles. Was forced to do.

Therefore, regarding the temple length adjustment,
Attempts were made to provide a special adjustable extension mechanism directly on the temple. As such a proposal, for example,
Two slide guides are provided on the temple, and the eyeglasses having an expandable and retractable temple that expands and contracts the length of the temple by rotating the knob of the screw screw (Japanese Patent Laid-Open No. 4-66914) and the expandable body on the temple and the spring There is a temple for eyeglasses (Japanese Patent Laid-Open No. 4-303815) in which the length of the temple is expanded and contracted by elastic force.

However, these temple expansion and contraction mechanisms require various parts and assemblies such as screws and springs in addition to the temples, and the length adjusting mechanism constructed by using these parts is very complicated. It was a structure. Therefore, there is a drawback that it takes time to manufacture this mechanism and the manufacturing cost increases.

[0007]

The present invention has been made in view of the above-mentioned drawbacks in the modern eyeglasses of the related art, and by using the modern with a metal pipe, the temple can be deeply inserted into the interior of the modern. Even if you do not insert the metal core of, the modern can be easily shape-corrected by hand bending, and going one step further, the length of the metal core of the temple is short and material saving and economical modern And to provide a spectacle temple using the same.

Another technical problem of the present invention is to change the depth of insertion of the metal core of the temple into the modern interior so that the length of the entire temple can be easily adjusted according to the head shape of each person. Modern, which can be adjusted and has a simple structure,
And to provide a spectacle temple using the same.

Further, another technical problem of the present invention is that, by devising a combination of a metal pipe and a synthetic resin material forming the modern, the modern and the modern interior can be provided with a complicated and delicate decorative pattern, And to provide a spectacle temple using the same.

First, a modern structure constructed by applying the present invention will be described with reference to FIGS. 1 and 2. The modern M of this embodiment includes a metal pipe 1 and a synthetic resin material 2. The metal pipe 1 is made of a metal material that can be easily plastically deformed by applying an external force, and provides the modern M with hand bending workability. Then, as shown in FIG.
The metal pipe 1 has an insertion pipe opening 11 at one end, and in a state where the insertion pipe opening 11 is exposed, the outer peripheral surface of the metal pipe 1 is made into a shape of an ear hook of spectacles by the synthetic resin material 2. It is covered. That is, as shown in FIG.
It has a double structure that is completely different from the conventional modern structure.

Now, a method for manufacturing the modern M of this embodiment will be described below. As a manufacturing method, a bonding method, an insert molding method, a metal pipe insertion method or the like can be adopted. First, an example in which the modern M is manufactured by using the bonding method will be shown. The outer diameter of the metal pipe 1 is 2.2 mm,
An annealed Ti pipe having a thickness of 0.4 mm and a length of 60 mm was used, and an acetyl cellulose plate was used as the synthetic resin material 2. This acetyl cellulose plate was cut into two pieces in the shape of an ear hook, and the Ti pipe was sandwiched between them to be bonded in a modern shape with a urethane adhesive. This pasting method is conventionally known as a modern manufacturing method.

Next, three examples of manufacturing the modern M using the insert molding method will be shown. In the first example, the metal pipe 1 has an outer diameter of 2.2 mm, a thickness of 0.4 mm and a length of 60.
Using annealed Ti pipe of mm, as the synthetic resin material 2,
A polyurethane elastomer was used. This polyurethane elastomer was coated on the outer peripheral surface of the Ti pipe using an insert molding method. In this example, since a polyurethane elastomer having a large rubber elasticity and a Shore hardness of 55 was used, a modern M having a very soft touch was obtained. In the second example, as the metal pipe 1, an N having an outer diameter of 2.2 mm, a thickness of 0.5 mm and a length of 60 mm is used.
Using the i-Cr alloy pipe, as the synthetic resin material 2,
Clear cellulose propionate was used. This Ni
-The surface of the Cr-based alloy pipe is gold-plated with a thickness of 2 μm, and the diamond-shaped cutting processing as shown in FIG. 3 is performed, and the gold plating is regularly removed to obtain gold and silver colors. A beautiful intersecting decorative pattern 13 was engraved, and an acrylic resin liquid was applied to the surface thereof to improve the corrosion resistance and the adhesion to the synthetic resin material 2. By coating the outer surface of the Ni-Cr alloy pipe that has been treated in this way with transparent cellulose propionate, you can see the beautiful diamond-cut decorative pattern 13 in which the gold and silver inside shine brightly. I got a nice modern M. In the third example, the metal pipe 1 has an outer diameter of 2.2 mm and a thickness of 0.
Use 4mm and 60mm length stainless steel pipe,
As the synthetic resin material 2, black cellulose propionate was used. A convex decorative pattern 13 'as shown in FIG. 4 is formed on the surface of this stainless pipe, and the convex decorative pattern 13' is formed.
The surface of 13 'was plated with gold. With this convex decorative pattern 13 'exposed, the outer peripheral surface of the stainless pipe was coated with black cellulose propionate. On this occasion,
By making the surfaces of the convex decorative pattern 13 'and cellulose propionate flush with each other, the modern M has a metallic pattern that is comfortable to wear and does not cause discomfort.
was gotten.

In addition to the materials used in the above example, the materials of the metal pipe 1 include Ti and A.
l, Cu, Ag, Au, Pt, Fe, Cr, Zn, M
A metal such as n or Co, or an alloy of a combination of these metals can be adopted. As the material of the synthetic resin material 2, synthetic resin such as soft vinyl chloride resin, silicone resin, polyamide resin, epoxy resin, ethyl vinyl acetate, polyester elastomer, polyether elastomer, polyamide elastomer and ionomer resin can be adopted. .

The structure of the spectacle temple constructed by applying the present invention will be described with reference to FIGS. The temple T of this embodiment includes a metal pipe 1, a synthetic resin material 2,
It consists of rod 3. Metal pipe 1 and synthetic resin material 2
Thus, the modern M as exemplified in the above-described embodiment is adopted, and the small diameter portion 31 of the rod 3 is inserted into the insertion port 11 of the modern M by a required depth and tightly fixed. As a fixing method, as shown in FIG. 7, a clasp 4 is attached to the fitting portion of the modern M and the rod 3 and caulked, or as shown in FIG. It is possible to hold the part 14 and the hooking part 32 at the end of the rod 3 by engaging the male and female. FIG. 5 shows a state in which the entire small diameter portion 31 of the rod 3 is inserted into the hollow portion 12 of the metal pipe 1. In FIG. 6, a portion of the small diameter portion 31 of the rod 3 is inserted into the hollow portion 12. The state is shown. As can be seen from these drawings, in the temple T of this embodiment, by changing the depth of insertion of the small diameter portion 31 of the rod 3 as necessary,
The length of the entire temple T can be adjusted. Therefore, the degree of freedom in adjusting the length of the temple T is remarkably greater than that of the conventional modern in which the length can be adjusted only by the bending condition of the modern itself, and the structure is extremely simple. Further, unlike the case of using the conventional modern, it is not necessary to insert the small diameter portion 31 of the rod 3 deep into the hollow portion 12 of the modern M. Therefore, since the length of the rod 3 can be shortened, the material cost can be greatly saved when a precious metal is used.

The embodiments of the present invention are generally as described above, but the present invention is by no means limited to the above-mentioned embodiments, and various modifications can be made within the scope of the claims. Thus, for example, it is possible to expose the pipe opening of the metal pipe from the end of the modern of the present embodiment and add decoration to the tip thereof to enhance the decorative effect. It goes without saying that it belongs to the target range.

[0020]

As described above with reference to the embodiments, according to the present invention, by using a modern plastic-deformable metal pipe built-in, the rod can be inserted deep inside the modern like a conventional modern. Since it is not necessary to do so, the length of the rod can be shortened, and in particular, when a rod made of an expensive material such as solid gold is used, the cost can be significantly reduced. Further, since the modern has a double structure composed of a metal pipe and a synthetic resin material, a complicated and delicate decorative pattern can be applied to the surface and the inside of the modern by devising a combination of these.

Further, it is possible to obtain a temple length adjusting mechanism by an extremely simple method of inserting a rod into a modern metal pipe without adopting a very complicated length adjusting mechanism in a conventional spectacle temple. it can. In addition, the length of the temple can be freely adjusted simply by changing the insertion depth of the rod, so the temple length required for the wearer's face does not match, so even if the glasses of your favorite design, It is possible to prevent situations such as having to replace temples or select other glasses. Therefore, its practical value is enormous.
