[Prior art]

 Since nickel-titanium alloys have ideal physical properties such as superelasticity and shape memory properties, the demand for their use is extremely high and they are put to practical use in various fields. This nickel-titanium-based superelastic alloy is widely used as a material for eyeglasses, and various advantages can be obtained by using it. For example, it becomes possible to improve the strength and corrosion resistance of eyeglasses, and to manufacture eyeglasses that are relatively lighter than eyeglasses using other materials. In addition, if a super elastic alloy is used for the eyeglass temples, the springiness of the temples is significantly improved, and even if a slight unreasonable force is applied to the temples, it will easily return to its original state.

However, since such a nickel-titanium-based superelastic alloy does not have good bondability with other materials, for example, the surface of a core material made of this superelastic alloy is covered with a coating material such as a synthetic resin. In the case of an eyeglass temple formed by wearing the eyeglasses, there is a drawback that the joint strength between the core material and the covering material is low. Further, in the spectacle temple having such a structure, the superelasticity property, which is an advantage, acts in reverse, and also acts as a demerit. That is, since the temple portion is easily elastically deformed, a load due to the elastic deformation is applied many times, and the peeling between the core material and the covering material gradually increases due to the load. Therefore, there are drawbacks that the coating material is peeled off from these joint ends, or cracks or cracks occur.

[Technical issues to be solved]

 The present invention has been made in view of the above-described problems in the conventional eyeglass temples using a superelastic alloy, and the periphery of the core made of a superelastic alloy material is covered with a covering material. In the broken temple member, by pressing one end of this covering material with the sleeve passed through the core material, it is possible to prevent the covering material from peeling from the core material, and at the same time, the sleeve has a function as a beautiful decoration. It is a technical subject to provide a decorative superelastic template for eyeglasses.

[0005]

[Means adopted for solving the problem]

 Means adopted by the present inventor to solve the above technical problems will be described below with reference to the accompanying drawings.

That is, according to the present invention, in the temple member 1 in which the periphery of the core material 11 made of a superelastic alloy material is covered with the coating material 12, at least one cutout having the sink hole 22 at the end of the shaft hole 21. The above technical problem is solved by adopting the peeling prevention means of covering the core material 11 with the sleeve 2 and crimping the core material 11 at a predetermined position and inserting the insertion end 13 of the covering material 12 into the sink hole 22 of the parting sleeve 2. Is characterized in that it has been solved.

【Example】

 Hereinafter, the present invention will be described in more detail with reference to the embodiments shown in the accompanying drawings. 1 is a perspective view of a spectacle temple of a first embodiment product configured by applying the present invention, FIG. 2 is an exploded sectional explanatory view showing a cross section of a main part of FIG. 1, and FIG. 3 is a first embodiment product. 4 is a perspective view of a sleeve used in FIG. 4, FIG. 4 is an exploded cross-sectional explanatory view showing a cross section of a main part of an eyeglass temple of a second embodiment product configured by applying the present invention, and FIG. FIG. 6 is a perspective view of an eyeglass temple of the third embodiment, and FIG. 6 is a cross-sectional view of a main part of FIG.

First, the spectacle temple of the first embodiment product configured by applying the present invention will be described. In FIG. 1, what is designated by reference numeral 1 is a temple member in which a core material 11 made of a nickel-titanium superelastic alloy material is covered with a covering material 12, and the parting sleeve 2 is provided on the core material 11. And is crimped near the base of the hinge piece 14. As the covering material 12, a colorful synthetic resin molded body such as an acrylic resin can be used. Further, as the parting sleeve 2, one made of an alloy such as nickel silver can be used. The covering material 12 may be covered by inserting the core material 11 through a parting sleeve 2 into a temple-shaped synthetic resin molded body having a hole for inserting the core material, or by insert molding. It is possible to adopt a method of coating the temple to which the parting sleeve is crimped with synthetic resin by processing. As shown in FIGS. 2 and 3, a shaft hole 21 is formed in the parting sleeve 2, and a sink hole 22 having the same diameter as that of the covering material 12 is formed at an end of the shaft hole 21. . By inserting the insertion end 13 of the covering material 12 into the sunk hole 22, the insertion end 13 is sandwiched between the core material 11 and the parting sleeve 2 and pressed against each other. As a result, it is possible to prevent the coating material from peeling off from the core material made of nickel-titanium superelastic alloy material with poor joining property and from cracking or cracking due to deformation of the small portion of the coating material. Become. Furthermore, the presence of the sleeve 2 allows a beautiful decoration in a smart form to be formed at the boundary between the hinge piece 14 and the covering material 12, so that it is possible to obtain a spectacle temple having a decoration function at the same time.

Further, a spectacle temple of a second embodiment product configured by applying the present invention will be described. As shown in FIG. 4, a small-diameter insertion end 13a is projectingly provided at the end of the covering material 12. By fitting the small-diameter insertion end 13a into the sink hole 22 of the parting sleeve 2, a spectacle temple with a smart appearance can be obtained without causing a step at the boundary between the parting sleeve 2 and the covering material 12.

Further, the spectacle temple of the third embodiment product configured by applying the present invention will be described. As shown in FIGS. 5 and 6, the third embodiment product is an example in which two parting sleeves 2 are provided at two positions of the temple. One of these parting sleeves 2 is the same as that of the first embodiment, and is attached near the base of the hinge piece 14. The other parting sleeve 2 is attached to the middle part of the temple, and sunk holes 22 are formed at both ends of the parting sleeve 2 in the middle part. The ends of the covering material 12 are fitted in these sink holes 22. By providing a plurality of parting sleeves 2 at a plurality of positions on the temple in this way, a spectacle temple having a more varied design can be obtained.

The embodiments of the present invention are generally as described above, but the present invention is not limited to the above-mentioned embodiments, and various modifications can be made within the scope of the “claim for utility model registration”. However, for example, it is possible to change the shape of the parting sleeve or to give a colorful decorative pattern to the surface of the sleeve, and it is said that any of these modifications belongs to the technical scope of the present invention. There is no end.

[0012]

[Effect of device]

 As described above with reference to the embodiments, according to the present invention, in a temple member in which a core material made of a superelastic alloy material is covered with a coating material, this coating is performed by a sleeve passed through the core material. Since one end of the material is hidden, the covering material is prevented from peeling off from the core material. Also, although there was a limit to the wall thickness of the covering material as the covering material becomes thin and cracks and cracks occur in the fore edge, by installing the sleeve, it is possible to make the covering material as thin as possible. In addition to being possible, the elastic effect of the core material can be fully exerted. In addition, the presence of the sleeve allows a beautiful decoration to be performed, and at the same time, the decoration function can be achieved, and the eyeglasses having an excellent design can be obtained. Therefore, the use of superelastic alloys in eyeglasses will be further expanded, and the industrial utility value will be great.
