本発明は、貴石、セラミックス、サファイヤ、ガラス、
アルマイト、超硬、ステライト等の素材を用いた時計用
針に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to precious stones, ceramics, sapphire, glass,
This invention relates to watch hands made of materials such as alumite, carbide, and stellite.

に、針の素材として貴石、セラミックス、サファイヤ等
を使用する提案があった。-Clocks are now required not only to display the time, but also to improve their design and enhance their decorative effect. Among the various proposals made for this purpose, there were proposals to use precious stones, ceramics, sapphires, etc. as materials for the needles.
従来技術は第３図の針の断面図に示すように、サファイ
ヤの針体６をノーカマ部７ａを一体成形した金属板７に
接着剤８を介して接着固定していた。In the prior art, as shown in the cross-sectional view of the needle in FIG. 3, a sapphire needle body 6 is adhesively fixed to a metal plate 7 having a nozzle part 7a integrally formed thereon with an adhesive 8.
この従来構造の針に於ては、モジュールの針軸に針を押

携帯衝撃強度を十分に満足するものが要望されているが
、現在は実現されていない。In the needle of this conventional structure, when the needle is pushed into the needle shaft of the module and assembled, the sapphire 6 often peels off or cracks from the metal plate 7, which impairs the ease of assembly. Also, when the watch is carried, the sapphire 6 is damaged by the metal plate 7 due to external impact.
There are a lot of market complaints that come out of the box. Furthermore, as watches have become thinner in recent years, the hands have become jewel-like and less than 150μ thick.
Although there is a demand for something that fully satisfies the impact strength of mobile phones, it has not been realized at present.

用針を提供することを目的とするものである。The object of the present invention is to eliminate the drawbacks of the conventional hands mentioned above, and to provide a thin watch hand in which the needle hook is firmly joined using materials such as precious stones, ceramics, sapphire, alumite, carbide, stellite, and glass. That is.

・Mechanically formed into a hook shape and anti-corrosion plated), 6 indicates a vapor phase plating layer, 4 indicates a wet plating layer, and 5 indicates solder. Cr is applied by sputtering to the back surface and hole of the sapphire outer body 1 formed into a needle shape with a thickness of 100μ.
A vapor phase plating layer 6 is formed with a film thickness of 0.3 μm.

Further, the metal forming the wet plating layer 4 may be Cr, Au, etc. in addition to Ni, and the film thickness is optimally in the range of 0.5 μm to 10 μm from the functional and economical viewpoints. The purpose of forming the vapor phase plating layer 6 is to obtain adhesion and a high-class appearance quality that cannot be obtained by wet plating. The purpose of forming the wet plating layer 4 is to improve the adhesion of the solder.

観である。Then, place the sapphire outer body 1 on a hot plate with the lower surface side facing upward, and insert the needle hook 2 into the sapphire outer body 1.
By inserting the needle into the hole and heating it at 250° C. to 300° C. for 5 to 15 minutes, the sapphire outer body 1 and the needle hook 2 are firmly soldered together. The 60-color vapor phase plating layer is visible on the lower surface of the sapphire outer body 1, giving the needle a very beautiful jewel-like appearance.

も発生しなかった。Even when the 100 .mu. thick sapphire needle completed in this example was pressed and assembled into the needle shaft of the module, there was no peeling of the needle hook 2 or cracking of the sapphire outer body 1. Also 100μ
As a result of evaluating the impact resistance of a watch with thick sapphire hands using an impact tester, the watch was found to have enough strength to meet the impact standards for watches. We also conducted a mobile phone test, and no problems occurred when using the device.
