本考案は時計の停止装置、特に針合せ操作時に時計輪列
を一時的に停止する停止装置の改良に関するものである
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a stop device for a timepiece, particularly a stop device for temporarily stopping a timepiece wheel train during a hand setting operation.
時計の針合せ操作時に時計輪列及び指示針の回転を停止
して正確な針合せを行なう為に従来より種々の停止装置
が提案されている。2. Description of the Related Art Various stopping devices have been proposed in the past in order to accurately set the hands of a watch by stopping the rotation of a watch wheel train and an indicator hand when setting the hands of a watch.
従来の停止装置は、針合せ操作と連動する停止レバーの
先端を時計輪列中の任意の歯車に当接させ、前述した時
計輪列の回転停止を行っていた。The conventional stop device stops the rotation of the timepiece train by bringing the tip of a stop lever, which is linked to the hand setting operation, into contact with an arbitrary gear in the timepiece train.
この従来装置では、歯車への当接作用を得るために停止
レバーはそれ自体弾性を有し、この結果、歯車の半径方
向への押圧力によって以下の欠点を生じていた。In this conventional device, the stop lever itself has elasticity in order to obtain an abutting action on the gear, and as a result, the following disadvantages occur due to the pressing force in the radial direction of the gear.
即ち、停止レバーが当接する歯車に直接大きな弾圧力が
加わる為歯車真の曲り及び歯形部の変形を生じるという
欠点があった。That is, since a large elastic force is directly applied to the gear that the stop lever contacts, there is a drawback that the gear is bent and the tooth profile is deformed.
更に、従来装置では、停止レバーの弾性を利用し、歯車
との当接状態で適正な弾圧力を得る為に操作レバーの形

。Furthermore, in conventional devices, in order to utilize the elasticity of the stop lever and obtain an appropriate elastic force when in contact with the gear, the shape and size accuracy or spring constant of the operating lever must be managed extremely accurately. It has the disadvantage of poor processing and assembly workability, and if the above-mentioned appropriate elastic force cannot be obtained, a good stopping action cannot be achieved, and in extreme cases, a stopping failure may occur during needle alignment. There were drawbacks such as:
従来の改良された装置として、停止レバーの弾圧力を利
用する事なく、輪列に停止用の特別の突起その他を設は
停止レバーと突起を係合する事により停止作用を得るも
のも提案されているが、この従来装置では特別な突起を
別個に設けなければならない等の欠点があった。As an improved conventional device, a device has been proposed in which a special protrusion or the like for stopping is provided on the wheel train and the stopping action is obtained by engaging the stop lever and the protrusion without using the elastic force of the stop lever. However, this conventional device has drawbacks such as the need to separately provide a special protrusion.
