ある。Still another object of the present invention is to improve ease of assembly and after-sales service by reducing the number of places to lubricate the calendar display feed wheel by smoothing the operation of the calendar display feed pawl.
従来の暦表示送り車の構造を第１図、第２図に示す。The structure of a conventional calendar display feeder wheel is shown in FIGS. 1 and 2.
第１図、第２図にふ−いて、暦表示送り爪１は暦表示車
４とかみ合い暦表示送り歯車５からの回転を暦表示車４
にｆ４する。Referring to FIGS. 1 and 2, the calendar display feed pawl 1 meshes with the calendar display wheel 4, and the rotation from the calendar display feed gear 5 is controlled by the calendar display wheel 4.
Press f4.
暦表示送り爪１のスラスト方向のガタを規制する送り水
神え９は暦表示送り車押え６でガタをもって押えられる
。A feed water holder 9 for regulating the play of the calendar display feed pawl 1 in the thrust direction is held down by a calendar display feed wheel presser 6 with no play.
従来の暦表示送り爪１は、暦表示車４を駆動するとき、
矢印７または矢印８のいずれかの方向に自由に移動して
し捷うため、送り水神え９が必要であり、組立性などに
支障があった。When the conventional calendar display feed pawl 1 drives the calendar display wheel 4,
In order to freely move in the direction of arrow 7 or arrow 8, a water feeder 9 is required, which poses a problem in ease of assembly.
従来の暦表示送り爪１は、暦表示送り歯車５、送り水神
え９、暦表示送り車押え６、などの寸法精度が悪い場合
、暦表示車４とのかみ合いが外れ、駆動不良が生じやす
かった。In the conventional calendar display feed pawl 1, if the dimensional accuracy of the calendar display feed gear 5, water feed gear 9, calendar display feed wheel holder 6, etc. is poor, the engagement with the calendar display wheel 4 is likely to disengage, resulting in drive failure. Ta.
従って、各部品精度を厳しく管理する必要があり、加工
性が悪かった。Therefore, it was necessary to strictly control the accuracy of each part, resulting in poor workability.
従来の暦表示送り爪１は、暦表示送り歯車５、送り水神
え９と摺動するため注油が必要であり、組立性、アフタ
ーサービス性などに支障があった。The conventional calendar display feed pawl 1 requires lubrication because it slides with the calendar display feed gear 5 and the water feed gear 9, which poses a problem in ease of assembly and after-sales service.
本考案はかかる欠点を除去したもので、暦表示送り爪先
側面全周に５°以上の勾配と、先端近傍の平面に暦表示
送り歯車を貫通して時計基板に接するピンを設けたもの
である。The present invention eliminates such drawbacks by providing an inclination of 5 degrees or more on the entire circumference of the side surface of the calendar display feed toe, and a pin that penetrates the calendar display feed gear and contacts the watch board on a plane near the tip. .
以下第３図、第４図に基づいて説明する。The explanation will be given below based on FIGS. 3 and 4.
第３図、第４図に釦いて、暦表示送り爪１１の先端近傍
の平面にピン１２と先側面全周に５°以上の勾装置３を
もうけである。As shown in FIGS. 3 and 4, a pin 12 is provided on the plane near the tip of the calendar display feed claw 11, and a tilt device 3 of 5 degrees or more is provided around the entire circumference of the tip side.
暦表示送り爪１１は暦表示車１４とかみ合い、暦表示送
り歯車１５からの回転を暦表示車１４に伝える。The calendar display feed pawl 11 meshes with the calendar display wheel 14 and transmits rotation from the calendar display feed gear 15 to the calendar display wheel 14.
暦表示送り車押え１６は暦表示送り歯車１５の押えかつ
回転中心である。The calendar display feed wheel presser 16 is a presser and rotation center of the calendar display feed gear 15.
本考案は暦表示送り爪１１により暦表示車１４を駆動す
るとき、５°以上の勾装置３により暦表示車１４から矢
印１７方向へ反力を受け、矢印１７方向へ移動する。In the present invention, when the calendar display wheel 14 is driven by the calendar display feed claw 11, a reaction force is received from the calendar display wheel 14 in the direction of the arrow 17 by the tilt device 3 of 5 degrees or more, and the calendar display wheel 14 moves in the direction of the arrow 17.
従って矢印１８方向への移動はなく、移動を規制する部
品は不要であり組立性などが向上する。Therefore, there is no movement in the direction of arrow 18, and no parts are required to restrict movement, improving ease of assembly.
さらに、本発明は、暦表示送り爪１１により暦表示車１
４を駆動するとき、ピン１２により矢印１７方向への移
動を時計基板１９で規制する。Furthermore, in the present invention, the calendar display wheel 1 is
When driving 4, movement in the direction of arrow 17 is restricted by pin 12 and clock board 19.
以上から矢印１７、矢印１８方向の両方向の移動は規制
されることになり暦表示車１４とは確実にかみ合い、駆
動不良は防げる。From the above, movement in both directions of arrows 17 and 18 is restricted, and the calendar display wheel 14 is reliably engaged with the calendar display wheel 14, thereby preventing drive failure.
本考案は矢印１８方向の移動を規制する部品がないため
、暦表示送り爪１１、暦表示送り歯車１５、暦表示送り
車押え１６などの寸法精度が悪くても、暦表示送り歯車
１５、暦表示送り爪１１の作動に影響がない。Since the present invention does not have any parts that restrict movement in the direction of the arrow 18, even if the dimensional accuracy of the calendar display feed pawl 11, the calendar display feed gear 15, the calendar display feed wheel presser 16, etc. is poor, the calendar display feed gear 15, the calendar The operation of the display feed claw 11 is not affected.
従って、各部品の精度管理をゆるめることができ、部品
加工が容易になる。Therefore, precision control of each component can be relaxed, and component processing becomes easier.
本考案は、暦表示送り爪１１が暦表示送り歯車１５、送
り爪押えなどとの摺動部がなく従って、暦表示送り爪１
１への無注油が可能となり組立性、アフターサービス性
が向上する。In the present invention, the calendar display feed claw 11 does not have a sliding part with the calendar display feed gear 15, the feed claw presser, etc.
1 without lubrication, which improves ease of assembly and after-sales service.
本考案は、上記に述べたような、効果があるとともに、
