ースのボタン部構造に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a wristwatch case, and more particularly to the structure of a button part of a wristwatch case whose outer skin is made of metal and whose inside is made of an insulating material such as synthetic resin.

第１図は平面図で、第２図は第１図のＡ−Ｂ縦断面図で
従来構造のうち最も一般的なボタン部構造を示したもの
で、第３図以降が、本考案の実施例を示したものである
。Figure 1 is a plan view, Figure 2 is a vertical sectional view taken along line A-B in Figure 1, and shows the most common conventional button structure. This is an example.

以下、これらの図面に基いて説明する。The following will explain based on these drawings.

第２図の従来構造は、最も普及している構造であり、金

６ｂに接して、電気的なスイッチ動作をさせるものであ
った。The conventional structure shown in FIG. 2 is the most popular structure, and has a hole 4 formed in a body 4 made of a metal outer skin 4a and an insulator 4b.
c is passed through button 1, and C ring 2 is bitten into the groove at the end of the button shaft from a direction perpendicular to the button shaft direction to lock the body 4 and button 1. When button 1 is pushed downward, the button returns. A contact spring 6a, which also served as a spring, was pushed down and brought into contact with the contact 6b, causing an electrical switch operation.

しかし、この従来構造のボタン１の材質に導電性の良い
金属等を使用すると、外皮４ａとボタン１の間でＭＣ気
のスパークを生じこのスパークがボタン１を通り接点バ
ネ６ａに入ってＩＣに影響を与え、時計表示が狂う欠点
があった。However, if a metal with good conductivity is used for the material of the button 1 of this conventional structure, a spark of MC air is generated between the outer cover 4a and the button 1, and this spark passes through the button 1 and enters the contact spring 6a, and is connected to the IC. This had the disadvantage that the clock display would be incorrect.

また従来の構造はＣリングをボタン軸と直角方向に喰付
かせるため、ボタンの組込が極めて困難で、保全サービ
ス等がしにくい等の欠点があった。Furthermore, in the conventional structure, the C-ring is attached perpendicularly to the button shaft, making it extremely difficult to assemble the button and making maintenance services difficult.

本考案は上記の欠点を解消するもので、金属ボタンの使
用をしても不具合がなく、組込が容易で保全サービスの
し易い腕時計ケースを提供する事を目的とする。The present invention solves the above-mentioned drawbacks, and aims to provide a wristwatch case that is free from defects even when metal buttons are used, is easy to assemble, and is easy to service.

以下、本考案の実施例について、第３図以降の図面に基
き説明する。Hereinafter, embodiments of the present invention will be described based on the drawings from FIG. 3 onwards.

第３図は本考案の要部断面図で、第４図は係止部材（以

５図は４ケボタンの時のボタン止め斜視図、第６図は２
ケボタンの時、ボタン止めの一部をバネとして構成した
時の要部断面図である。Fig. 3 is a cross-sectional view of the main part of the present invention, Fig. 4 is an example of a locking member (hereinafter referred to as a button stopper) in the case of 2 buttons, and Fig. 5 is a perspective view of the button stopper in the case of 4 buttons. , Figure 6 is 2
FIG. 6 is a cross-sectional view of a main part when a part of the button stopper is configured as a spring in the case of a button.

第３図において、ボタン１１は胴４のボタン穴４ｃに貫
通させる。In FIG. 3, the button 11 is passed through the button hole 4c of the body 4.

ボタン１１の端部には突起１１ｂを形成し更に外周部に
溝１１ａを形成する。A protrusion 11b is formed at the end of the button 11, and a groove 11a is further formed at the outer periphery.

この突起部１１ｂに絶縁体より成るボタン止め１２の穴
をボタン軸方向に圧入し、以って固定する。A hole in a button stopper 12 made of an insulator is press-fitted into the projection 11b in the axial direction of the button, thereby fixing the button.

このように固定されたボタン止め１２はその端部１２ｂ
が胴内面に当接するのでボタン１１が抜ける事はなく、
下端部１２ａは接点バネ６ａと接し押し上げられる力を
受け、図のように落ち着く。The button stopper 12 fixed in this way has its end 12b
Button 11 will not come off as it will come into contact with the inner surface of the body.
The lower end portion 12a comes into contact with the contact spring 6a, receives a force of pushing up, and settles down as shown in the figure.

第３図から明らかなように、ボタン１１と胴外皮４ａが
その電位差によりスパークしてもボタン止め１２が絶縁
体であるため、スパークの影響は接点バネ６ａに入らず
、ＩＣにも入らず、従来の不具合は解消できた。As is clear from FIG. 3, even if a spark occurs due to the potential difference between the button 11 and the body shell 4a, since the button stopper 12 is an insulator, the influence of the spark will not enter the contact spring 6a or the IC. Previous problems have been resolved.

また、ボタン止め１２はボタンの軸方向から圧入するの
みで組付が終了するため極めて簡便に組付、保全サービ
スが可能となった。In addition, since the button stopper 12 can be assembled by simply press-fitting it from the axial direction of the button, assembly and maintenance services are extremely easy.

第４図、第５図は腕時計が複数のボタンを有する時に、
２個、または４個のボタン止めを一体的に構成して、よ
り組付を要具にしたものの一実施例である。Figures 4 and 5 show that when a wristwatch has multiple buttons,
This is an embodiment in which two or four button fasteners are integrally constructed to make assembly easier.

第６図は一体的に２個のボタン止メを形威し、更に、つ
なぎの部分１２Ｃを裏ブタに当接させ、つなぎ部の有す
るバネ力によりボタン押し後の復帰を可能にした時の一
実施例である。Figure 6 shows a state in which two button clasps are integrally formed, and the joint part 12C is brought into contact with the back lid, allowing the button to return after being pressed by the spring force of the joint part. This is an example.
