【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、針表示式の腕時計の時刻表示と時刻修正の
機能切換のための時刻修正構造に関する。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a time adjustment structure for switching the functions of time display and time correction of a hand-display wristwatch.
本発明は、針表示式の腕時計の時刻修正構造におい
て、時刻表示輪列と時刻修正輪列の噛み合い切換を外部
操作部材と切換レバーを使い、関係輪列の断面噛み合い
切換により行い、構造の簡素化、薄型化、小型化したも
のである。According to the present invention, in the time adjustment structure of a hand display type wristwatch, the mesh switching between the time display wheel train and the time correction wheel train is performed by using the external operation member and the switching lever by switching the cross-section meshing of the related wheel train. It has been made smaller, thinner, and smaller.
従来、時刻修正構造として、第３図に示すように巻真
１と係合するオシドリ２、さらにオシドリ２と係合する
カンヌキ３の作動により、巻真１と係合するつづみ車４
と、時刻修正輪列の小鉄車５の噛み合い切換を行ってい
た。また、時刻修正時には、巻真１の回転によりつづみ
車４が回され、小鉄車５→日の裏中間車６→日の裏車７
→二番車８に力が伝達され時刻を修正するが、この際、
駆動モーター部のローター10まで回転が伝わった場合、
磁極位置が変わり、運針スタート時にミスリが起きるた
め、二番車からローターの間の一つの番車に回転止めの
ための規正レバー９を当てていた。またこの場合は通常
二番車にすべり構造を持たせ、時刻修正輪列のみ回転す
る様にしていた。Conventionally, as a time correction structure, as shown in FIG. 3, a clutch wheel 4 engaged with the winding stem 1 by the operation of a mandrel 2 engaged with the winding stem 1 and a cannula 3 engaged with the mandrel 2.
Then, meshing switching of the small iron wheel 5 of the time adjustment train wheel was performed. Further, when adjusting the time, the handwheel 4 is rotated by the rotation of the winding stem 1, and the small iron wheel 5 → the intermediate vehicle 6 behind the day → the rear vehicle 7 behind the day
→ The force is transmitted to the second wheel & pinion 8 to correct the time.
When the rotation is transmitted to the rotor 10 of the drive motor,
Since the magnetic pole position has changed and mishandling occurs at the start of hand movement, the train wheel setting lever 9 for stopping rotation was applied to one wheel between the second wheel and the rotor. Also, in this case, the second wheel usually had a slip structure so that only the time adjustment train wheel could rotate.
しかし、従来構造では、構造が複雑で部品点数も多
く、部品コストダウンや組立性の向上、更に時計体の薄
型、小型化を進める上で、大きな障害となっていた。ま
た、部品形状も複雑なため、部品加工性も悪く、量産上
の品質安定化の上でも、困難をともなっていた。However, in the conventional structure, the structure is complicated and the number of parts is large, which has been a major obstacle in reducing the cost of parts, improving the assembling property, and further reducing the thickness and size of the timepiece body. Further, since the shape of the parts is complicated, the workability of the parts is poor, and it is difficult to stabilize the quality in mass production.
そこで、本発明は、この様な問題点を解決するもので
あり、その目的は部品点数を削減し、薄型小型化、低コ
ストの時刻修正構造を提供するところにある。Therefore, the present invention is to solve such a problem, and an object thereof is to provide a time adjustment structure in which the number of parts is reduced, the size and size are reduced, and the cost is reduced.

徴とする。The time adjustment structure for a wristwatch according to the present invention is a time adjustment structure for a hand indicating wristwatch that decelerates the rotation of a drive motor by a train wheel to drive a pointer wheel to which a pointer is attached and displays the time. And a switching lever that engages with the external operating member, and the first end of the switching lever is disposed in a rotation transmission path that transmits the rotation of the drive motor to the pointer wheel.
The rotation shaft of the second gear arranged on the rotation transmission path for transmitting the rotation of the external operating member to the pointer wheel is engaged, and the switching lever is set to the time correction state. , Disengaging the first gear, meshing the second gear, and meshing the first gear in the time display state,
Further, the meshing state of the first and second gears is switched so as to disengage the meshing of the second gear.
第１図に、本発明の実施例を示す要部の平面図、第２
図に、その断面図を示す。11は巻真、12は巻真11に断面
係合する切換レバー、13は切換レバーの先端と係合する
日の裏中間車、14は同じく三番車である。FIG. 1 is a plan view of an essential part showing an embodiment of the present invention, and FIG.
The cross-sectional view is shown in the figure. Reference numeral 11 is a winding stem, 12 is a switching lever that engages with the winding stem 11 in section, 13 is an intermediate wheel behind the day that engages with the tip of the switching lever, and 14 is a third wheel.
時刻表示を行っている時は、第２図（ａ）、（ｂ）に
示す様にローター15の回転力は、ローター15→五番車16
→四番車17→三番車14→二番車18→日の裏車19、日の裏
中間車13と伝達される。この状態では、切換レバー12の
曲げ先端部Ａは、巻真12の凹部Ｂに入っており、三番車
14と二番車18の係合部Ｃは噛み合い、日の裏中間車13と
小鉄車21の係合部Ｄは噛み合いが外れている。このた
め、伝達トルクは小鉄車21に伝わらない。また、切換レ
バー12は、巻真11の平面方向の位置決めも同時に行って
いる。When the time is displayed, the rotational force of the rotor 15 is changed from the rotor 15 to the fifth wheel 16 as shown in FIGS. 2 (a) and 2 (b).
→ No. 4 wheel 17 → No. 3 wheel 14 → No. 2 wheel 18 → Hino back car 19 and Hino back car 13 transmitted. In this state, the bent tip portion A of the switching lever 12 is in the concave portion B of the winding stem 12, and the third wheel
The engaging portion C of 14 and the center wheel & pinion 18 meshes with each other, and the engaging portion D of the intermediate wheel 13 on the back of the day and the small wheel & pinion 21 disengage from each other. Therefore, the transmission torque is not transmitted to the setting wheel 21. The switching lever 12 also positions the winding stem 11 in the plane direction at the same time.
時刻修正時は、巻真11を引き出すと、切換レバー12の
曲げ先端部Ａは、巻真11の凸部にそって乗り上げ、巻真
11の次の凹部Ｅに入り位置決めされる。凹部Ｅは凹部Ｂ
より外径が大きく、このため、切換レバー12は断面方向
に持ち上げられ、切換レバー12の先端と係合する三番車
14、日の裏中間車13は上方向に上げられ、二番車18と三
番車14の係合部Ｃは噛み合いが外れ、逆に小鉄車21と日
の裏中間車13は噛み合い状態となる。When adjusting the time, when the winding stem 11 is pulled out, the bending tip portion A of the switching lever 12 rides up along the convex portion of the winding stem 11 to set the winding stem 11.
The concave portion E next to 11 is entered and positioned. Recess E is recess B
It has a larger outer diameter, so that the switching lever 12 is lifted in the cross-sectional direction and engages with the tip of the switching lever 12
14, the intermediate wheel 13 on the back of the day is raised upward, the engagement portion C of the second wheel 18 and the third wheel 14 is disengaged, and conversely, the small wheel 21 and the intermediate wheel 13 on the back of the day are in a meshed state. Become.
この状態で、時刻修正のため巻真11を回転すると、回
転力はつづみ車22→小鉄車21→日の裏中間車13→日の裏
車19→二番車18と伝達され時刻修正が可能となる。しか
し、二番車18と三番車14は噛み合いが外れているため回
転は伝わらず、ローター15の磁極位置は変わらない。In this state, when the winding stem 11 is rotated to adjust the time, the torque is transmitted to the clutch wheel 22 → Kotetsu car 21 → Hino intermediate car 13 → Hino reverse car 19 → Second wheel 18 to correct the time. It will be possible. However, since the second wheel & pinion 18 and the third wheel & pinion 14 are out of mesh with each other, the rotation is not transmitted and the magnetic pole position of the rotor 15 does not change.
また、巻真11の位置決めも切換レバー12の曲げ先端部
Ａと巻真12の凹部Ｂ、Ｅにより実現され従来の様な位置
決め部品も不要となる。Further, the positioning of the winding stem 11 is realized by the bent tip end portion A of the switching lever 12 and the concave portions B and E of the winding stem 12, so that the conventional positioning parts are not required.
また、従来二番車18に採用していたすべり構造、規正
レバーも不要となり構造が簡素化される。Further, the sliding structure and the train wheel setting lever which have been conventionally used for the center wheel & pinion 18 are not required, and the structure is simplified.
以上述べた様に、本発明は、時刻修正を行うための複
雑な切換構造を、巻真と切換レバーの二部品を削減し、
併せて二番車の構造簡略化を実現しており、時計小型

立性の向上と、その効果は大である。As described above, the present invention has a complicated switching structure for adjusting the time, which reduces the two parts of the winding stem and the switching lever,
At the same time, the structure of the center wheel & pinion has been simplified, the timepiece has become smaller and thinner, the number of parts has been reduced, and the parts cost has been reduced.
