Description

本発明は、時差修正機構（時修正機構）、該機構を備えたムーブメント、及び該ムーブメントを備えた時差修正時計に係わる。   The present invention relates to a time difference correction mechanism (time correction mechanism), a movement including the mechanism, and a time difference correction timepiece including the movement.

揺動する車を用いて、プラス方向（進む方向）又はマイナス方向（遅れる方向）のいずれか一方のみに時差修正を行い得るようにした時差修正機構は知られている（例えば、特許文献１）。   There is known a time difference correction mechanism that can perform time difference correction only in one of a plus direction (forward direction) and a minus direction (delay direction) using a swinging vehicle (for example, Patent Document 1). .

しかしながら、この特許文献１の技術では、時差修正機構で行い得る方向とは逆方向に時差を修正しようとすると、時差修正の手間がかかり過ぎる。   However, in the technique of Patent Document 1, if it is attempted to correct the time difference in the direction opposite to the direction that can be performed by the time difference correction mechanism, it takes too much time to correct the time difference.

一方、両方向の時差修正を可能にすべく、通常の巻真とは別に時差修正用に第二の巻真を設けることは提案されている（特許文献２）。   On the other hand, in order to enable correction of the time difference in both directions, it has been proposed to provide a second winding stem for correcting the time difference separately from the normal winding stem (Patent Document 2).

しかしながら、この特許文献２の技術では、デザインを制約するだけでなく、スペースを占有する無駄な部品が多くなる。   However, the technique of Patent Document 2 not only restricts the design, but also increases unnecessary parts that occupy space.

更に、単一の巻真を用いて時差修正を行わせる機構として、巻真の引出し操作に応じておしどりやかんぬきを介して時差修正用の輪列が係脱するようにしたものも提案されている（特許文献３）。   Furthermore, as a mechanism for correcting the time difference using a single winding stem, a mechanism in which the train wheel for correcting the time difference is engaged or disengaged via a lever or a pin according to the pulling operation of the winding stem has been proposed. (Patent Document 3).

しかしながら、この特許文献３の技術は、時差修正輪列自体を係脱することから十分なスペースを確保する必要があるだけでなく、その係脱動作を支えるべく強度の高い部品を備える必要もある。   However, the technique of this Patent Document 3 requires not only a sufficient space to engage / disengage the time difference correction wheel train itself, but also a high-strength part to support the engagement / disengagement operation. .

本発明は、前記諸点に鑑みなされたものであって、その目的とするところは、所望の引出位置において巻真を回す方向を変えるだけで時差を増減させ得るだけでなく、揺動や並進等による係脱動作なくしても筒車から巻真側への回転の伝達を避け得る時差修正機構、該機構を備えたムーブメント、及び該ムーブメントを備えた時差修正時計を提供することにある。   The present invention has been made in view of the above-mentioned points, and the object of the present invention is not only to increase or decrease the time difference by simply changing the direction in which the winding stem is rotated at a desired drawing position, but also to swing, translate, etc. An object of the present invention is to provide a time difference correction mechanism capable of avoiding transmission of rotation from the hour wheel to the winding stem side without the engagement / disengagement operation by the movement, a movement provided with the mechanism, and a time difference correction timepiece provided with the movement.

本発明の時差修正機構は、前記目的を達成すべく、巻真の回転に応じて連続的に回転される時修正駆動車であってピン及び円弧状長穴のうちの一方の係合要素を備えたものと、歯のある有歯部と該歯を欠く欠歯部とを周方向に交互に備え前記時修正駆動車と同軸に配置された時修正間欠車であって前記時修正駆動車の前記一方の係合要素に遊嵌され係合されるべく前記ピン及び前記円弧状長穴のうちの他方の係合要素を備えたものとを有し、前記時修正間欠車が筒歯車に噛合された筒車側時修正輪列の歯車に対して前記有歯部で間欠的に噛合されるように構成されている。   The time difference correcting mechanism of the present invention is a correction driving wheel that is continuously rotated in accordance with the rotation of the winding stem to achieve the above object, and includes one engagement element of a pin and an arc-shaped elongated hole. A time-correcting intermittent vehicle having a toothed portion having teeth and a missing tooth portion lacking the teeth alternately arranged in the circumferential direction and arranged coaxially with the time-correcting driving vehicle. The other one of the pin and the arc-shaped elongated hole to be engaged with the one engagement element of the first and second engagement elements. The toothed portion is intermittently engaged with the gear of the hour wheel side correction wheel train engaged.

本発明の時差修正機構では、「巻真の回転に応じて連続的に回転される時修正駆動車であってピン及び円弧状長穴のうちの一方の係合要素を備えたもの」が設けられているので、巻真の正逆方向の回転に応じて時差修正駆動車が対応する方向に連続的に回転され得る。また、本発明の時差修正機構では、「歯のある有歯部と該歯を欠く欠歯部とを周方向に交互に備え時修正駆動車と同軸に配置された時修正間欠車であって時修正駆動車の前記一方の係合要素に遊嵌され係合されるべくピン及び円弧状長穴のうちの他方の係合要素を備えたもの」が設けられているので、時差修正駆動車の前記対応する方向への連続的な回転に応じて、時修正駆動車ピン及び円弧状長穴のうちの一方の係合要素が、時修正間欠車のピン及び円弧状長穴のうちの他方の係合要素に係止されるところまで回転された後、時修正間欠車が時修正駆動車と同一の方向に回転され得る。更に、本発明の時差修正機構では、「時修正間欠車が筒歯車に噛合された筒車側時修正輪列の歯車に対して有歯部で間欠的に噛合されるように構成されている」ので、時修正間欠車の有歯部が筒車側時修正輪列の歯車に噛合される毎に筒車側時修正輪列の歯車を介して筒歯車が回転されて、時差修正が行われ得る。   In the time difference correcting mechanism of the present invention, there is provided “a driving vehicle that is corrected when continuously rotated according to the rotation of the winding stem and includes one engaging element of a pin and an arc-shaped elongated hole”. Therefore, the time difference correcting drive wheel can be continuously rotated in the corresponding direction according to the forward / reverse rotation of the winding stem. In the time difference correcting mechanism of the present invention, the time-correcting intermittent wheel is provided with a toothed portion having teeth and a missing tooth portion lacking the teeth alternately in the circumferential direction and arranged coaxially with the time-correcting driving vehicle. Since there is provided the other of the pin and the arc-shaped elongated hole so as to be loosely fitted and engaged with the one engagement element of the time correction driving vehicle, the time difference correction driving vehicle is provided. In response to the continuous rotation of the hour correction drive wheel pin and the arc-shaped elongated hole, the other engagement element of the hour correction intermittent wheel pin and the arc-shaped elongated hole Then, the hour correction intermittent wheel can be rotated in the same direction as the hour correction driving vehicle. Further, in the time difference correction mechanism of the present invention, “the time correction intermittent wheel is intermittently engaged with the gear of the hour wheel correction wheel train engaged with the cylindrical gear at the toothed portion. Therefore, every time the toothed portion of the hour correction intermittent wheel is meshed with the gear of the hour correction wheel train, the cylindrical gear is rotated via the gear of the hour correction wheel train, and the time difference is corrected. Can be broken.

ここで、筒歯車は、時針が取付けられた筒歯車部分又はこれと同期回転する部分をいう。この時針が取付けられた筒歯車部分は、典型的には、通常運針輪列と直接的に噛合している別の筒歯車部分に対しては所定トルクの範囲内で係合しており、該所定トルクを超えるトルクを受けた際には、通常運針輪列と直接的に噛合している別の筒歯車部分に対して相対回転可能である。   Here, the cylindrical gear refers to a cylindrical gear portion to which an hour hand is attached or a portion that rotates synchronously therewith. The cylindrical gear portion to which the needle is attached at this time is typically engaged within a predetermined torque range with another cylindrical gear portion that is directly meshed with the normal needle train. When a torque exceeding a predetermined torque is received, it can rotate relative to another cylindrical gear portion that is directly meshed with the normal wheel train.

加えて、本発明の時差修正機構では、「巻真の回転に応じて連続的に回転される時修正駆動車であってピン及び円弧状長穴のうちの一方の係合要素を備えたものと、歯のある有歯部と該歯を欠く欠歯部とを周方向に交互に備え時修正駆動車と同軸に配置された時修正間欠車であって時修正駆動車の前記一方の係合要素に遊嵌され係合されるべくピン及び円弧状長穴のうちの他方の係合要素を備えたもの」とが設けられていて、「時修正間欠車が筒歯車に噛合された筒車側時修正輪列の歯車に対して有歯部で間欠的に噛合されるように構成されている」ので、筒車側時修正輪列の歯車と時修正間欠車の欠歯部とが対面している場合には筒歯車から時修正間欠車を介した時修正駆動車への回転の伝達ないし該時修正駆動車を介した巻真への回転の伝達が禁止されるのは勿論として、（当初は筒車側時修正輪列の歯車と時修正間欠車の有歯部とが噛合していて）筒歯車が回転した場合に該筒歯車の回転に伴って当初は時修正間欠車が回転する場合であっても、筒車側時修正歯車に対して時修正間欠車の欠歯部が対面するようになると筒車側時修正輪列の歯車から時修正間欠車への回転の伝達が断たれるから、（仮に一時的に生じたとしても）筒歯車から時修正間欠車を介した時修正駆動車への回転の伝達ないし該時修正駆動車を介した巻真への回転の伝達を速やかに禁止し得る。しかも、時修正間欠車の一つの有歯部分の回転がピン及び円弧状長穴のうちの一方の係合要素と他方の係合要素との遊嵌領域で解消される場合には、時修正間欠車の回転が時修正駆動車に影響を及ぼさないので、巻真側への回転の伝達が仮に生じても最低限に抑えられ得る。   In addition, in the time difference correcting mechanism of the present invention, “a driving vehicle that is corrected when continuously rotated according to the rotation of the winding stem and includes one engaging element of a pin and an arc-shaped elongated hole” And a tooth-correcting intermittent vehicle having a toothed portion having teeth and a missing tooth portion lacking the teeth alternately in the circumferential direction and arranged coaxially with the time-correcting driving vehicle. A cylinder in which the hour-correcting intermittent wheel is meshed with a cylindrical gear. `` It is configured to be intermittently engaged with the gear of the vehicle side correction wheel train at the toothed portion '', so that the gear of the hour wheel correction wheel train and the toothless portion of the hour correction intermittent train are When facing each other, transmission of rotation from the cylindrical gear to the hour correction driving vehicle via the hour correction intermittent vehicle or rotation to the winding stem via the hour correction driving vehicle is performed. As a matter of course, the rotation of the cylindrical gear when the cylindrical gear rotates (initially, the gear of the hour correction wheel train on the hour side of the hour wheel and the toothed portion of the hour correction intermittent wheel mesh). As a result, even if the hour correction intermittent wheel rotates at the beginning, if the tooth missing portion of the hour correction intermittent wheel faces the hour correction wheel, the gear of the hour correction wheel train Since the transmission of rotation to the time correction intermittent vehicle is interrupted, the rotation transmission from the cylindrical gear to the time correction driving vehicle via the time correction intermittent vehicle (even if temporarily generated) or the time correction drive Transmission of rotation to the winding stem through the vehicle can be prohibited immediately. Moreover, when the rotation of one toothed portion of the hour correction intermittent wheel is eliminated in the loose fitting region between one engagement element and the other engagement element of the pin and the arc-shaped elongated hole, the time correction Since the rotation of the intermittent wheel does not affect the hour corrective driving vehicle, even if transmission of rotation to the winding stem side occurs, it can be minimized.

本発明の時差修正機構では、典型的には、前記時修正間欠車の前記欠歯部に嵌る時修正間欠車躍制爪部を備えた時修正躍制レバーを有する。   The time difference correction mechanism of the present invention typically includes a time correction jump control lever provided with a time correction intermittent vehicle jump control claw portion that fits into the missing tooth portion of the hour correction intermittent wheel.

その場合、時差修正間欠車の回転位置を適切に規正し得、筒車側時修正輪列の歯車が通常は時修正間欠車の欠歯部に対面するようにしておくことにより、筒車から巻真側への回転の伝達の生起を確実に避け得る。また、他の歯車との回転位相を合わせて噛合いを適切に行わせ易い。   In that case, the rotational position of the time difference correcting intermittent wheel can be properly adjusted, and the gear of the hour wheel on the hour wheel correction wheel train normally faces the toothless part of the time correcting intermittent wheel so that The transmission of rotation to the winding stem side can be surely avoided. In addition, it is easy to appropriately engage with the other gears by matching the rotation phase.

本発明の時差修正機構では、典型的には、前記時修正躍制レバーが前記時修正間欠車躍制爪部の反対側の端部に前記筒車側時修正輪列の前記歯車に対して躍制動作を行う筒車側時修正歯車躍制爪部を備える。   In the time difference correction mechanism of the present invention, typically, the hour correction jump control lever is located at the opposite end of the hour correction intermittent vehicle jump control claw portion with respect to the gear of the hour wheel correction wheel train. An hour wheel correction gear jump control claw portion that performs jump control operation is provided.

その場合、時修正間欠車に欠歯部があるにもかかわらず、時修正間欠車の有歯部と筒車側時修正輪列の歯車の歯との回転位相を確実に合わせて、歯同士の突っ張り等の虞を最低限に抑えた状態で確実に噛合させ得る。   In that case, even though the hour correction intermittent wheel has a missing tooth part, the rotational phase of the toothed part of the hour correction intermittent wheel and the gear teeth of the hour wheel of the hour wheel correction wheel is surely matched, It is possible to surely engage with each other in a state where the risk of stretching is minimized.

本発明の時差修正機構では、典型的には、前記時修正躍制レバーを支える時修正躍制レバー作動ピンと、該時修正躍制レバー作動ピンの変位を許容する案内部と、前記時修正躍制レバー作動ピンを前記時修正間欠車の方へ弾性的に押す時修正躍制解除レバーとを有する。   In the time difference correction mechanism of the present invention, typically, the time correction jump lever operating pin that supports the time correction jump control lever, a guide portion that allows the displacement of the time correction jump lever operation pin, and the time correction jump And a correction jump release release lever when the brake lever operating pin is elastically pushed toward the time correction intermittent vehicle.

その場合、時修正躍制解除レバーが、時修正躍制レバーを躍制位置と躍制解除位置との間で確実に位置決めし得、時修正躍制レバーの筒車側時修正歯車躍制爪部による筒車側時修正輪列の歯車に対する規正を完全に解除し得るので、余計なクリック感を生じさせることまで回避し得る。   In this case, the hour correction jump release lever can reliably position the hour correction jump lever between the jump position and the jump release position, and the hour correction gear jump lever claw of the hour correction jump lever. Since it is possible to completely cancel the restriction on the gear of the hour wheel side correction wheel train by the portion, it is possible to avoid even generating an extra click feeling.

本発明の時差修正機構では、典型的には、前記時修正躍制解除レバーは、前記時修正間欠車の前記有歯部に係合した際に、前記時修正間欠車から離間する向きにされて前記時修正躍制レバー作動ピンの後退を許容し、前記時修正躍制レバーによる躍制動作を解除するように構成される。   In the time difference correction mechanism of the present invention, typically, the time correction jump release release lever is oriented away from the time correction intermittent vehicle when engaged with the toothed portion of the time correction intermittent vehicle. The time correction jump control lever actuating pin is allowed to move backward, and the jump operation by the time correction jump control lever is released.

本発明の時差修正機構では、典型的には、支持基板が複数の案内ピンを備え、前記時修正躍制レバー及び前記時修正躍制解除レバーが複数の前記案内ピンの整列方向に変位されるように該案内ピンに遊嵌される長穴を備える。   In the time difference correction mechanism of the present invention, typically, the support substrate includes a plurality of guide pins, and the time correction jump control lever and the time correction jump release lever are displaced in the alignment direction of the plurality of guide pins. Thus, a long hole that is loosely fitted to the guide pin is provided.

その場合、時修正躍制解除レバー及び時修正躍制レバーが安定に位置決め案内され得る。また、複数の案内ピンを共用して動作位置を重複させることにより、時修正躍制レバー作動ピンに対する力の付与や解除を行ない易くなり、複雑化する動作を比較的簡単な構成で実現し得る。   In this case, the hour correction jump release lever and the hour correction jump release lever can be stably positioned and guided. Also, by sharing a plurality of guide pins and overlapping the operation positions, it becomes easier to apply and release the force to the hour correction jump lever operating pin, and a complicated operation can be realized with a relatively simple configuration. .

本発明の時差修正機構では、典型的には、前記巻真と前記時修正駆動車とをつなぐ複数の歯車からなる巻真側時修正輪列を有する。   The time difference correcting mechanism of the present invention typically has a winding stem side correcting wheel train composed of a plurality of gears connecting the winding stem and the hour correcting driving wheel.

その場合、時修正駆動車が巻真から離れた所望位置に配置され得る。   In that case, the hour correction drive wheel can be arranged at a desired position away from the winding stem.

本発明のムーブメントは、前記目的を達成すべく、上述のような時差修正機構（時修正機構）と、時修正用引出位置に設定可能な前記巻真とを備え、該時修正用引出位置に設定された際に該巻真の回転により前記時修正駆動車が回転されるように構成される。   In order to achieve the above object, the movement of the present invention includes the time difference correction mechanism (time correction mechanism) as described above and the winding stem that can be set at the time correction drawer position. When set, the hour correction drive wheel is configured to rotate by rotation of the winding stem.

その場合、巻真を時差修正用の引出し位置に設定するだけで、巻真の回転方向に応じて時差が進む方向にも遅れる方向にも時差修正（時修正）が行われ得る。   In this case, the time difference can be corrected (time correction) in both the direction in which the time difference advances and the direction in which the time difference lags in accordance with the rotation direction of the winding stem simply by setting the winding stem to the drawing position for correcting the time difference.

本発明の時差修正時計は、前記目的を達成すべく、前記ムーブメントすなわち上述のような時差修正機構を備えたムーブメントを有する。   The time difference correction timepiece of the present invention has the movement, that is, the movement provided with the time difference correction mechanism as described above, in order to achieve the object.

In addition, as long as three long holes are circular arc shape, they do not need to be concentric. The number of arc-shaped elongated holes 45 may be two or less or four or more. The hour correction drive wheel 40 is engaged with the fifth hour correction transmission wheel 39 by the gear portion 44.

時修正間欠車５０は、図１〜図４に加えて図６の（ａ）及び（ｂ）に拡大して示したように、概ね円板状の本体５１と、該本体５１の外周縁５２のうち周方向の複数箇所（この例では５箇所）に等間隔に形成された有歯部５３と、該有歯部５３，５３の間の円弧状すなわち部分円筒状の欠歯部５４と、周方向の複数箇所（この例では３箇所）に周方向に等間隔に形成された係合要素としての係合ピンないし係合突起部５５を備える。係合突起５５の数並びに周方向及び径方向の位置は、時修正駆動車４０の円弧状長穴４５の数並びに周方向及び径方向の位置と同じである。各有歯部５３は少なくとも一つの歯、典型的には、複数（この例では３個）の歯５６を備える。各有歯部５３の周方向の長さは同一であり、各欠歯部５４の周方向の長さも同一である。但し、場合によっては、有歯部５３の周方向の長さにバラツキがあってもよい。   As shown in FIGS. 6A and 6B in addition to FIGS. 1 to 4, the hour correction intermittent wheel 50 includes a substantially disc-shaped main body 51 and an outer peripheral edge 52 of the main body 51. Toothed portions 53 formed at equal intervals in a plurality of circumferential locations (5 locations in this example), an arcuate portion between the toothed portions 53, 53, that is, a partially cylindrical missing tooth portion 54, Engagement pins or engagement protrusions 55 as engagement elements formed at equal intervals in the circumferential direction are provided at a plurality of circumferential locations (three locations in this example). The number of engaging projections 55 and the positions in the circumferential direction and the radial direction are the same as the number of arc-shaped elongated holes 45 of the hour correction drive wheel 40 and the positions in the circumferential direction and the radial direction. Each toothed portion 53 includes at least one tooth, typically a plurality (three in this example) of teeth 56. The circumferential length of each toothed portion 53 is the same, and the circumferential length of each missing tooth portion 54 is also the same. However, depending on the case, the circumferential length of the toothed portion 53 may vary.

時修正間欠車５０の三つの係合要素としてのピン５５，５５，５５は、時修正駆動車４０の三つの係合要素としての円弧状長穴４５，４５，４５に丁度遊嵌される。すなわち、時修正間欠車５０の一つのピン５５が時修正駆動車４０の対応する円弧状長穴４５のＨ１方向端部４５ａに位置する場合、時修正間欠車５０の残りの二つのピン５５，５５（図１では図示せず）も時修正駆動車４０の対応する円弧状長穴４５，４５（図１では図示せず）のＨ１方向端部４５ａ，４５ａ（図１では図示せず）に位置する。また、時修正間欠車５０の一つのピン５５が時修正駆動車４０の対応する円弧状長穴４５のＨ２方向端部４５ｂに位置する場合、時修正間欠車５０の残りの二つのピン５５，５５（図１では図示せず）も時修正駆動車４０の対応する円弧状長穴４５，４５（図１では図示せず）のＨ２方向端部４５ｂ，４５ｂ（図１では図示せず）に位置する。   The pins 55, 55, 55 as the three engaging elements of the hour correction intermittent wheel 50 are loosely fitted just into the arc-shaped elongated holes 45, 45, 45 as the three engaging elements of the hour correction driving wheel 40. That is, when one pin 55 of the hour correction intermittent wheel 50 is located at the H1 direction end 45a of the corresponding arc-shaped elongated hole 45 of the hour correction driving wheel 40, the remaining two pins 55 of the hour correction intermittent wheel 50, 55 (not shown in FIG. 1) is also connected to H1 direction end portions 45a and 45a (not shown in FIG. 1) of corresponding arc-shaped elongated holes 45 and 45 (not shown in FIG. 1) of the hour correction drive wheel 40. To position. Further, when one pin 55 of the hour correction intermittent wheel 50 is located at the H2 direction end 45b of the corresponding arc-shaped elongated hole 45 of the hour correction driving wheel 40, the remaining two pins 55, 55 (not shown in FIG. 1) is also connected to H2 direction end portions 45b and 45b (not shown in FIG. 1) of the corresponding arc-shaped elongated holes 45 and 45 (not shown in FIG. 1) of the hour correction drive wheel 40. To position.

従って、時修正駆動車４０がＨ１方向に回転されると、時修正駆動車４０の円弧状長穴４５，４５，４５はＨ２方向端部４５ｂ，４５ｂ，４５ｂで時修正間欠車５０のピン５５，５５，５５に当たって時修正間欠車５０をＨ１方向に回す。一方、時修正駆動車４０がＨ２方向に回転されると、時修正駆動車４０の円弧状長穴４５，４５，４５はＨ１方向端部４５ａ，４５ａ，４５ａで時修正間欠車５０のピン５５，５５，５５に当たって時修正間欠車５０をＨ２方向に回す。   Therefore, when the hour correction drive wheel 40 is rotated in the H1 direction, the arc-shaped elongated holes 45, 45, 45 of the hour correction drive wheel 40 are the pin 55 of the hour correction intermittent wheel 50 at the end portions 45b, 45b, 45b in the H2 direction. , 55, and 55, the hour correction intermittent vehicle 50 is rotated in the H1 direction. On the other hand, when the hour correction driving wheel 40 is rotated in the H2 direction, the arc-shaped elongated holes 45, 45, 45 of the hour correction driving wheel 40 are pins 55 of the hour correction intermittent driving wheel 50 at the H1 direction end portions 45a, 45a, 45a. , 55, and 55, the hour correction intermittent wheel 50 is rotated in the H2 direction.

なお、筒車側時修正伝え輪列６は、この例では、一つの車すなわち第七時修正伝え車２８からなる。第七時修正伝え車２８は、中心軸線ＪのまわりでＪ１，Ｊ２方向に回転可能で、第一筒歯車部１２ｃに噛合し（図３及び図４参照）、時修正間欠車５０の有歯部５３に向き合うと（即ち、時修正間欠車５０のうち有歯部５３が第七時修正伝え車２８の方に向く回転位相になると）、該有歯部５３と噛合可能である。なお、第七時修正伝え車２８が時修正間欠車５０の欠歯部５４に向き合うと（即ち、時修正間欠車５０のうち欠歯部５４が第七時修正伝え車２８の方に向く回転位相になると）、時修正間欠車５０と第七時修正伝え車２８との間における歯の噛合いがなくなるので、時修正間欠車５０と第七時修正伝え車２８との間における回転の伝達はなくなる。   In this example, the hour correction transmission wheel train 6 on the hour wheel side includes one car, that is, the seventh correction transmission wheel 28. The seventh hour corrector transmission wheel 28 can rotate in the J1 and J2 directions around the central axis J, meshes with the first cylindrical gear portion 12c (see FIGS. 3 and 4), and the toothed teeth of the hour correction intermittent wheel 50. When facing the portion 53 (that is, when the toothed portion 53 of the hour correction intermittent wheel 50 is in a rotational phase toward the seventh hour correction transmission wheel 28), the toothed portion 53 can be engaged. When the seventh correction transmission wheel 28 faces the missing tooth portion 54 of the hour correction intermittent wheel 50 (that is, the rotation of the missing tooth portion 54 of the hour correction intermittent wheel 50 toward the seventh correction transmission wheel 28). When the phase is reached), the tooth engagement between the hour correction intermittent wheel 50 and the seventh hour correction transmission wheel 28 is eliminated, so that the rotation is transmitted between the hour correction intermittent wheel 50 and the seventh hour correction transmission wheel 28. Will disappear.

下板２１には、一対の案内ピン２３，２３及びばね受ピン２４及びレバーアガキ決めピン２５が植設されている。また、時修正躍制レバー作動ピン９０が下板２１及び時修正輪列受２２によってＫ１，Ｋ２に変位可能に支持されている。すなわち、時修正躍制レバー作動ピン９０は、大まかには、ピン状軸部９１とフランジ状部９２とからなり、より詳しくは、両端側に大径部９３，９４を備えると共に中間に小径部９５を備える。時修正躍制レバー作動ピン９０は、下板２１側の大径部９３において該下板２１の長穴２１ａ内にＫ１，Ｋ２方向に変位可能に遊嵌され、フランジ状部９２において時修正輪列受２２の細長い凹部２２ａ内にＫ１，Ｋ２方向に変位可能に遊嵌されている。   On the lower plate 21, a pair of guide pins 23, 23, a spring receiving pin 24, and a lever post fixing pin 25 are implanted.

In this K1 direction biased position, the inclined surface portions 87, 87 on both sides of the claw-like engaging portion 86 are separated from the side edges of the toothed portion 53 of the hour correction intermittent wheel 50, and the concave portion 88 of the claw-like engaging portion 86 is It is separated from the missing tooth portion 54 of the hour correction intermittent wheel 50. On the other hand, during time correction (time difference correction), the time correction jump release lever 80 is pushed by the toothed portion 53 of the hour correction intermittent wheel 50 at the claw-like engaging portion 86 and is biased in the K2 direction. The corrected jump control lever operating pin 90 is allowed to retract in the K2 direction.

時修正躍制レバー７０は、図１〜図４に加えて図７の（ａ）及び（ｂ）に拡大して示したように、概ね長方形状の本体部７１と、時修正躍制レバー作動ピン９０でＫ１方向に支えられるばね部７２と、該ばね部７２の先端部に形成された第七時修正伝え車２８の筒車側時修正伝え車躍制爪部としての第七時修正伝え車躍制爪部７３とを備える。本体部７１は、一対の案内ピン２３，２３に係合されて本体部７１のＫ１，Ｋ２方向の変位を許容する長穴７４を備えると共に、先端部７５に時修正間欠車５０に対して躍制動作をする時修正間欠車躍制爪部７６を備える。時修正間欠車躍制爪部７６は、概ね直線状ないし平面状の両側縁の傾斜面部７７，７７と、中央の円弧状凹部７８とを有する。凹部７８の曲率半径は、時修正間欠車５０の有歯部５３の歯先の包絡線の曲率半径と実際上一致する。時修正躍制レバー７０の爪状係合部７６は、両側縁の傾斜面部７７，７７で時修正間欠車５０の有歯部５３の側縁に係合して時修正間欠車５０の欠歯部５４に嵌り込んだり、円弧状凹部７８で時修正間欠車５０の有歯部５３に乗り上げたりする。   As shown in FIGS. 7 (a) and 7 (b) in addition to FIGS. 1 to 4, the hour correction jump control lever 70 has a substantially rectangular main body 71 and a time correction jump control lever operated.

A correction intermittent vehicle jump control claw portion 76 is provided when the braking operation is performed. The hour correction intermittent vehicle jump control claw portion 76 has inclined surface portions 77, 77 on both side edges that are generally linear or planar, and an arcuate concave portion 78 in the center. The radius of curvature of the concave portion 78 actually coincides with the radius of curvature of the envelope of the tooth tip of the toothed portion 53 of the hour correction intermittent wheel 50. The claw-like engaging portion 76 of the hour correction jump control lever 70 is engaged with the side edge of the toothed portion 53 of the hour correction intermittent wheel 50 by the inclined surface portions 77, 77 on both side edges, and the missing tooth of the hour correction intermittent wheel 50. It fits into the part 54, or rides on the toothed part 53 of the hour correction intermittent wheel 50 with the arc-shaped recess 78.

時修正躍制解除レバー８０の爪部８６が時修正間欠車５０の欠歯部５４に嵌り込み該時修正躍制解除レバー８０の作用下で時修正躍制レバー作動ピン９０がＫ１方向端部に位置する場合において、時修正躍制レバー７０の爪部７６が時修正間欠車５０の欠歯部５４に嵌り込み該時修正間欠車躍制爪部７６が時修正間欠車５０を規正するＫ１方向偏倚位置にあるときには、ばね腕部７２が本体７１に対して後退するようにＭ１方向に揺動し得るので、第七時修正伝え車躍制爪部７３による第七時修正伝え車２８の規正が解除される。一方、時修正躍制解除レバー８０の爪部８６が時修正間欠車５０の欠歯部５４に嵌り込み該時修正躍制解除レバー８０の作用下で時修正躍制レバー作動ピン９０がＫ１方向端部に位置する場合において、時修正躍制レバー７０の爪部７６が時修正間欠車５０の有歯部５３に乗り上げて該時修正躍制レバー７０の時修正間欠車躍制爪部７６が時修正間欠車５０の規正を行わないＫ２方向偏倚位置にあるときには、ばね腕部７２が時修正躍制レバー作動ピン９０によってＫ１方向に押されて本体７１に対してＭ２方向に揺動するので、第七時修正伝え車躍制爪部７３が第七時修正伝え車２８を規正する。さらに、時修正躍制解除レバー８０の爪部８６が時修正間欠車５０の有歯部５３に乗り上げて該時修正躍制解除レバー８０がＫ２方向に偏倚した場合において、時修正躍制レバー７０の爪部７６が時修正間欠車５０の有歯部５３に乗り上げて該時修正躍制レバー７０の時修正間欠車躍制爪部７６が時修正間欠車５０の規正を行わないＫ２方向偏倚位置にあるときには、ばね腕部７２が本体７１に対して後退するようにＭ１方向に揺動し得るので、第七時修正伝え車躍制爪部７３による第七時修正伝え車２８の規正が解除される。   The claw portion 86 of the hour correction jump release lever 80 is fitted into the toothless portion 54 of the hour correction intermittent wheel 50, and the hour correction jump lever operating pin 90 is at the end in the K1 direction under the action of the hour correction jump release lever 80. In this case, the claw portion 76 of the hour correction jump control lever 70 is fitted into the toothless portion 54 of the hour correction intermittent wheel 50, and the hour correction intermittent vehicle jump control claw portion 76 regulates the time correction intermittent wheel 50. When in the direction biased position, the spring arm portion 72 can swing in the M1 direction so as to move backward with respect to the main body 71, so that the seventh correction transmission wheel 28 of the seventh correction transmission wheel 28 by the seventh correction transmission wheel jump control claw portion 73 can be obtained. The regulation is released. On the other hand, the claw portion 86 of the hour correction jump release lever 80 is fitted into the toothless portion 54 of the hour correction intermittent wheel 50, and the hour correction jump release lever operating pin 90 moves in the K1 direction under the action of the hour correction jump release lever 80. In the case of being located at the end, the claw portion 76 of the hour correction jump control lever 70 rides on the toothed portion 53 of the hour correction intermittent gear 50 and the hour correction intermittent vehicle jump control claw portion 76 of the hour correction jump control lever 70 is When the hour correction intermittent wheel 50 is not in the K2 direction bias position, the spring arm 72 is pushed in the K1 direction by the hour correction jump lever operating pin 90 and swings in the M2 direction with respect to the main body 71. The seventh correction transmission wheel jumping claw portion 73 regulates the seventh correction transmission wheel 28. Furthermore, when the claw portion 86 of the hour correction jump release lever 80 rides on the toothed portion 53 of the hour correction intermittent wheel 50 and the hour correction jump release lever 80 is biased in the K2 direction, the hour correction jump release lever 70 K2 direction bias position where the claw portion 76 of the hour rides on the toothed portion 53 of the hour correction intermittent vehicle 50 and the hour correction intermittent vehicle jumping claw portion 76 of the hour correction jump control lever 70 does not correct the hour correction intermittent vehicle 50 Since the spring arm 72 can swing in the M1 direction so as to move backward with respect to the main body 71, the regulation of the seventh correction transmission wheel 28 by the seventh correction transmission jump control pawl 73 is released. Is done.

次に、以上の如く構成された時差修正機構を備えたムーブメントを有する時差修正時計における筒車１２と巻真３０との間における回転の伝達及び非伝達について、図１から図９に加えて、図１０から図１６に基づいて説明する。   Next, regarding transmission and non-transmission of rotation between the hour wheel 12 and the winding stem 30 in the time difference correcting timepiece having a movement having the time difference correcting mechanism configured as described above, in addition to FIGS. 1 to 9, This will be described with reference to FIGS.

まず、筒車１２の回転が巻真３０に与える影響について説明する。   First, the influence of the rotation of the hour wheel 12 on the winding stem 30 will be described.

図１からわかるように、筒車側時修正伝え車６をなす第七時修正伝え車２８が時修正複合車構造体５の時修正間欠車５０の欠歯部５４に対面していて、第七時修正伝え車２８と時修正間欠車５０との噛合が実際上解除されている場合、筒車１２の回転に伴って第七時修正伝え車２８が回転しても、該第七時修正伝え車２８の回転は時修正間欠車５０に伝達されず、時修正複合車構造体５が回転しないので、巻真側時修正伝え輪列４の車３９，３７，３５，３３，３１も回転しないから、筒車１２の回転は巻真３０に影響を及ぼさない。   As can be seen from FIG. 1, the seventh hour correction transmission wheel 28 that forms the hour correction transmission wheel 6 of the hour wheel face the missing tooth portion 54 of the hour correction intermittent wheel 50 of the hour correction compound vehicle structure 5. When the engagement between the seven o'clock correction transmission wheel 28 and the hour correction intermittent wheel 50 is actually released, even if the seventh hour correction transmission wheel 28 rotates as the hour wheel 12 rotates, the seventh hour correction The rotation of the transmission wheel 28 is not transmitted to the hour correction intermittent wheel 50, and the hour correction compound vehicle structure 5 does not rotate. Therefore, the cars 39, 37, 35, 33, 31 of the winding stem side correction transmission wheel train 4 also rotate. Therefore, the rotation of the hour wheel 12 does not affect the winding stem 30.

また、時修正間欠車５０の回転位相が異なっていて、時修正間欠車５０の有歯部５３が第七時修正伝え車２８に対面する位置にあって、時修正間欠車５０の有歯部５３の歯５６が第七時修正伝え車２８の歯と噛合っている場合であっても、筒車１２の回転に伴って時修正間欠車５０が多少回転するだけで、時修正間欠車５０の欠歯部５４が第七時修正伝え車２８に対面するようになるので、その後は、上記のように、筒車１２の回転が巻真３０に影響を及ぼさなくなることは同様である。   Further, the rotational phase of the hour correction intermittent wheel 50 is different, and the toothed portion 53 of the hour correction intermittent wheel 50 is in a position facing the seventh hour correction transmission wheel 28, and Even when the teeth 56 of the 53 are meshed with the teeth of the seventh hour correction transmission wheel 28, the hour correction intermittent wheel 50 is only slightly rotated as the hour wheel 12 is rotated. Since the missing tooth portion 54 faces the seventh hour correction transmission wheel 28, thereafter, the rotation of the hour wheel 12 does not affect the winding stem 30 as described above.

なお、時修正間欠車５０が筒車１２の回転に応じて回転される僅かな間についていえば、時修正間欠車５０の係合ピン５５が時修正駆動車４０の円弧状長穴４５内で採っている位置に応じて、場合によっては、時修正間欠車５０の係合ピン５５が時修正駆動車４０の円弧状長穴４５内で移動するだけで時修正間欠車５０の回転が時修正駆動車４０に伝達されることなく終わることもあり得る。   Note that the engagement pin 55 of the hour correction intermittent wheel 50 is within the arc-shaped elongated hole 45 of the hour correction driving wheel 40 as long as the hour correction intermittent wheel 50 is rotated according to the rotation of the hour wheel 12. Depending on the position taken, in some cases, the rotation of the hour correction intermittent wheel 50 is corrected by simply moving the engagement pin 55 of the hour correction intermittent wheel 50 within the arc-shaped elongated hole 45 of the hour correction driving wheel 40. It may end without being transmitted to the drive vehicle 40.

また、場合によっては、原理的には、時修正間欠車５０の係合ピン５５の回転移動により該係合ピン５５が時修正駆動車４０の円弧状長穴４５の端部４５ａ又は４５ｂを押して時修正駆動車５５を多少回転させることもあり得る。そのような場合、時修正駆動車５５の多少の回転に従って、巻真側時修正伝え輪列４の車３９，３７，３５，３３，３１を介して巻真３０が僅かに回転される。但し、その後、時修正間欠車５０の欠歯部５４で回転の伝達が断たれるようになると、巻真３０が回転されなくなることは、前述の通りである。   In some cases, in principle, the engaging pin 55 pushes the end 45a or 45b of the arc-shaped elongated hole 45 of the hour correction drive wheel 40 by the rotational movement of the engagement pin 55 of the hour correction intermittent wheel 50. The hour correction drive wheel 55 may be rotated slightly. In such a case, the winding stem 30 is slightly rotated through the wheels 39, 37, 35, 33, 31 of the winding stem side correction transmission wheel train 4 according to the slight rotation of the hour correction driving wheel 55. However, after that, when the transmission of rotation is cut off by the toothless portion 54 of the hour correction intermittent wheel 50, the winding stem 30 is not rotated as described above.

より詳しくは、通常は、時修正躍制レバー７０が時修正間欠車５０の欠歯部５４に係合して該時修正間欠車５０を規正するので、当該規正状態では、時修正間欠車５０の欠歯部５４が第七時修正伝え車２８に対面する。従って、通常は、筒車１２から巻真３０に回転が伝達される虞は実際上ない。   More specifically, normally, the hour correction jump control lever 70 is engaged with the toothless portion 54 of the hour correction intermittent wheel 50 to regulate the hour correction intermittent wheel 50. Therefore, in the correction state, the hour correction intermittent wheel 50 is set. The missing tooth portion 54 faces the seventh hour correction transmission wheel 28. Therefore, normally, there is practically no possibility that rotation is transmitted from the hour wheel 12 to the winding stem 30.

いずれにしても、時修正間欠車５０に欠歯部５４があるので、筒車１２の回転が巻真３０に伝達されるのを最低限に抑え得、通常は、時修正間欠車５０の欠歯部５４が第七時修正伝え車２８に対面するので、筒車１２の回転が巻真３０に伝達されるのを避け得る。   In any case, since the hour-correcting intermittent wheel 50 has the missing tooth portion 54, the rotation of the hour wheel 12 can be minimized and transmitted to the winding stem 30. Since the tooth portion 54 faces the seventh hour correction transmission wheel 28, the rotation of the hour wheel 12 can be prevented from being transmitted to the winding stem 30.

次に、以上の如く構成された時差修正機構を備えたムーブメントを有する時差修正時計において、巻真一段目位置Ｂ１において、巻真３０をまわして、時修正（時差修正）を行う場合の操作及び動作について、図１から図９に加えて、図１０から図１６に基づいて詳しく説明する。   Next, in the time difference correction timepiece having a movement having the time difference correction mechanism configured as described above, an operation for performing time correction (time difference correction) by turning the winding stem 30 at the winding stem first stage position B1 and The operation will be described in detail with reference to FIGS. 10 to 16 in addition to FIGS.

巻真一段目位置Ｂ１において、巻真３０が中心軸線Ｃのまわりで回転されていない図１の巻真３０の回転位置Ｐ０ないし時差修正機構１の状態Ｓ０では、時修正躍制解除レバー８０は、ばね部８２のばね力の作用下で、腕部８３によって時修正躍制レバー作動ピン９０をガイド孔２１ａ内でＫ１方向端部に押付け、Ｋ１方向偏倚位置Ｑ０を採る。この状態では、腕部８３で作動ピン９０に係止された時修正躍制解除レバー８０の係合爪部８６は、その傾斜面部８７，８７が時修正間欠車５０の有歯部５３，５３の側縁から離間し、且つその先端の円弧状凹部８８が時修正間欠車５０の欠歯部５４から離間している。また、この状態Ｓ０では、時修正躍制レバー７０の時修正間欠車躍制爪部７６は、その傾斜面部７７，７７が時修正間欠車５０の有歯部５３，５３の側縁に当接し、その先端の円弧状凹部７８が有歯部５３，５３間の欠歯部５４に嵌り込んだ規正位置Ｔ０を採る。従って、この状態Ｓ０では、時修正躍制レバー７０の時修正間欠車躍制爪部７６によって規正された時修正間欠車５０は基準位置Ｒ０を採る。また、この状態Ｓ０では、筒車側時修正伝え輪列６を構成する第七時修正伝え車２８は基準位置Ｒ０にある時修正間欠車５０の欠歯部５４に対面し、両者の間においては回転の伝達はない。   At the first position B1 of the winding stem, the winding stem 30 is not rotated about the central axis C. In the rotation position P0 of the winding stem 30 in FIG. Under the action of the spring force of the spring portion 82, the arm portion 83 presses the hour correction jumper lever operating pin 90 against the end portion in the K1 direction within the guide hole 21a to take the K1 direction bias position Q0. In this state, the engaging claw portion 86 of the correction jump release release lever 80 when the arm portion 83 is locked to the operating pin 90 has the inclined surface portions 87 and 87 of the toothed portions 53 and 53 of the hour correction intermittent wheel 50. The arcuate concave portion 88 at the tip is separated from the tooth missing portion 54 of the hour correction intermittent wheel 50. Further, in this state S0, the hour correction intermittent vehicle jump control claw portion 76 of the hour correction jump control lever 70 has its inclined surface portions 77 and 77 abutting against the side edges of the toothed portions 53 and 53 of the hour correction intermittent vehicle 50. The arcuate concave portion 78 at the tip thereof takes the setting position T0 in which the toothed portion 53, 53 is fitted into the toothless portion 54. Therefore, in this state S0, the hour correction intermittent wheel 50 set by the hour correction intermittent vehicle jump control claw portion 76 of the hour correction jump control lever 70 takes the reference position R0. In this state S0, the seventh hour correction transmission wheel 28 constituting the hour correction transmission wheel train 6 on the hour wheel side faces the toothless portion 54 of the correction intermittent wheel 50 when it is at the reference position R0. There is no transmission of rotation.

この巻真一段目位置Ｂ１において、時差修正ないし時修正を行うべく巻真３０が中心軸線ＣのまわりでＣ１方向に回転されると、巻真側時修正伝え輪列４を介して、時修正複合車構造体５の時修正駆動車４０がＨ１方向に回転される。従って、図１１に示したように、時修正駆動車４０は円弧状長穴４５のＨ２方向端部４５ｂで時修正間欠車５０のピン５５に係合して、時修正間欠車５０をＨ１方向に回し始める。その結果、時修正間欠車５０が時修正躍制レバー７０の躍制爪部７６の上流側に位置する有歯部５３の隣接側縁５３ａで時修正躍制レバー７０の躍制爪部７６の傾斜面部７７を押してＫ２方向に変位させて時修正躍制レバー７０のばね部７２を作動ピン９０に押付け、更に、ばね部７２のばね力に抗してＫ２方向に変位させ始める。このとき、巻真３０は回転位置Ｐ１にあり、時差修正機構１は状態Ｓ１を採り、時修正間欠車５０は僅かに回転した位置Ｒ１を採り、時修正躍制レバー７０はＫ２方向に僅かに後退した位置Ｔ１を採る。なお、状態Ｓ１では、時修正躍制解除レバー８０はＫ１方向偏倚位置Ｑ０に保たれる。   When the winding stem 30 is rotated around the central axis C in the direction C1 to correct the time difference or the time at the first position B1 of the winding stem, the time is corrected via the winding stem side correction transmission wheel train 4. When the composite vehicle structure 5 is used, the correction drive vehicle 40 is rotated in the H1 direction. Therefore, as shown in FIG. 11, the hour correction driving wheel 40 is engaged with the pin 55 of the hour correction intermittent wheel 50 at the H2 direction end portion 45b of the arc-shaped elongated hole 45, and the hour correction driving wheel 50 is moved in the H1 direction. Start turning to. As a result, the hour correction intermittent wheel 50 is located at the adjacent side edge 53a of the toothed portion 53 located on the upstream side of the jumping claw portion 76 of the hour correction jump control lever 70. The inclined surface portion 77 is pushed and displaced in the K2 direction to press the spring portion 72 of the hour correction jump control lever 70 against the operating pin 90, and further starts to be displaced in the K2 direction against the spring force of the spring portion 72. At this time, the winding stem 30 is in the rotation position P1, the time difference correction mechanism 1 takes the state S1, the hour correction intermittent wheel 50 takes the slightly rotated position R1, and the hour correction jump control lever 70 slightly in the K2 direction. The retracted position T1 is taken. In the state S1, the hour correction jump release lever 80 is kept at the K1 direction bias position Q0.

巻真３０が、中心軸線ＣのまわりでＣ１方向に更に回転されて、図１２に示したように、回転位置Ｐ２に達すると、巻真側時修正伝え輪列４を介して、時修正複合車構造体５の時修正駆動車４０がＨ１方向に回転され、時修正間欠車５０が有歯部５３の側縁５３ａで時修正躍制レバー７０の躍制爪部７６の隣接傾斜面部７７を更に押して時修正躍制レバー７０をＫ２方向に変位させる。その結果、時修正躍制レバー７０のばね部７２が作動ピン９０でＭ２方向に撓められて、第七時修正伝え車躍制爪部７３が筒車側時修正伝え輪列６をなす第七時修正伝え車２８の歯部に対する規正位置に近付けられる。このとき、時差修正機構１は状態Ｓ２を採り、時修正間欠車５０は更に少しだけ回転した位置Ｒ２を採り、時修正躍制レバー７０はＫ２方向に僅かに後退した位置Ｔ２を採る。なお、状態Ｓ２においても、時修正躍制解除レバー８０はＫ１方向偏倚位置Ｑ０に保たれる。   When the winding stem 30 is further rotated in the direction C1 around the central axis C and reaches the rotational position P2, as shown in FIG. 12, the time correction composite is transmitted via the winding stem side correction transmission wheel train 4. The hour correction driving wheel 40 of the vehicle structure 5 is rotated in the H1 direction, and the hour correction intermittent wheel 50 is moved at the side edge 53a of the toothed portion 53 by the adjacent inclined surface 77 of the jumping claw 76 of the hour correction jumper lever 70. When further pressed, the correction jump control lever 70 is displaced in the K2 direction. As a result, the spring portion 72 of the hour correction jump control lever 70 is bent in the M2 direction by the operating pin 90, and the seventh hour correction transmission wheel jump control claw portion 73 forms the hour correction transmission wheel train 6 that forms the hour wheel transmission correction gear train 6. The seven o'clock correction transmission wheel 28 is brought close to the setting position for the tooth portion. At this time, the time difference correction mechanism 1 takes the state S2, the hour correction intermittent wheel 50 takes a position R2 that is further rotated slightly, and the hour correction jump control lever 70 takes a position T2 slightly retracted in the K2 direction. Even in the state S2, the hour correction jump release release lever 80 is maintained at the K1 direction bias position Q0.

巻真３０が、中心軸線ＣのまわりでＣ１方向に更に回転されて、図１３に示したように、回転位置Ｐ３に達すると、巻真側時修正伝え輪列４を介して、時修正複合車構造体５の時修正駆動車４０がＨ１方向に回転され、時修正間欠車５０が有歯部５３の側縁５３ａで時修正躍制レバー７０の躍制爪部７６の隣接傾斜面部７７を更に押して時修正躍制レバー７０をＫ２方向に変位させ、時修正間欠車５０の有歯部５３の先端が、実際上、時修正躍制レバー７０の傾斜面部７７と円弧状凹部７８との境界に達する。その結果、時修正躍制レバー７０のばね部７２が作動ピン９０でＭ２方向に更に撓められて、第七時修正伝え車躍制爪部７３が筒車側時修正伝え輪列６をなす第七時修正伝え車２８の歯部に嵌り込む規正位置を採る。このとき、時差修正機構１は状態Ｓ３を採り、時修正間欠車５０は回転位置Ｒ３を採り、時修正躍制レバー７０はＫ２方向に後退した位置Ｔ３を採る。時修正躍制レバー７０があるが故に、時修正間欠車５０が回転位置Ｒ３に達すると、時修正間欠車５０の下流側の有歯部５３が、第七時修正伝え車躍制爪部７３によって規正されたばかりの第七時修正伝え車２８の歯に、該有歯部５３の側縁で、突っ張りの虞なく確実に噛合い始める。筒車側時修正伝え輪列６を構成する第七時修正伝え車２８は、実際上まだ回転されておらず、筒車側時修正伝え車躍制爪部としての第七時修正伝え車躍制爪部７３は初期位置Ｕ０にある。なお、状態Ｓ３においても、時修正躍制解除レバー８０はＫ１方向偏倚位置Ｑ０に保たれる。   When the winding stem 30 is further rotated in the direction C1 around the central axis C and reaches the rotational position P3 as shown in FIG. 13, the time correction compound is transmitted via the winding stem side correction transmission wheel train 4. The hour correction driving wheel 40 of the vehicle structure 5 is rotated in the H1 direction, and the hour correction intermittent wheel 50 is moved at the side edge 53a of the toothed portion 53 by the adjacent inclined surface 77 of the jumping claw 76 of the hour correction jumper lever 70. Further, the hour correction jump control lever 70 is displaced in the K2 direction so that the tip of the toothed portion 53 of the hour correction intermittent wheel 50 is actually the boundary between the inclined surface portion 77 of the hour correction jump control lever 70 and the arc-shaped recess 78. To reach. As a result, the spring portion 72 of the hour correction jump control lever 70 is further bent in the M2 direction by the operating pin 90, and the seventh hour correction transmission wheel jump control claw portion 73 forms the hour wheel transmission correction train wheel 6. The correct position for fitting into the tooth portion of the seventh correction transmission wheel 28 is taken. At this time, the time difference correction mechanism 1 takes the state S3, the hour correction intermittent wheel 50 takes the rotational position R3, and the hour correction jump control lever 70 takes the position T3 retracted in the K2 direction. Because of the hour correction jump control lever 70, when the hour correction intermittent wheel 50 reaches the rotational position R3, the toothed portion 53 on the downstream side of the hour correction intermittent wheel 50 is changed to the seventh hour correction transmission wheel jump control pawl 73. The teeth of the seventh correction transmission wheel 28 just set by the gears are surely started to be engaged at the side edges of the toothed portion 53 without fear of tension. The seventh hour correction transmission wheel 28 constituting the hour wheel transmission correction train wheel 6 is not actually rotated yet, and the seventh hour correction transmission wheel jump as the hour wheel correction transmission wheel jumping claw portion. The pawl portion 73 is in the initial position U0. Even in the state S3, the hour correction jump release lever 80 is kept at the K1 direction bias position Q0.

巻真３０が、中心軸線ＣのまわりでＣ１方向に更に回転されて、図１４に示したように、回転位置Ｐ４に達すると、巻真側時修正伝え輪列４を介して、時修正複合車構造体５の時修正駆動車４０がＨ１方向に回転され、時修正間欠車５０が有歯部５３の側縁５３ａで時修正躍制解除レバー８０の係合爪部８６の隣接傾斜面部８７に係合してこれを押し、時修正躍制解除レバー８０をＫ２方向に変位させ始める。図１４の状態Ｓ４では、時修正間欠車５０が回転位置Ｒ４に達し、時修正躍制解除レバー８０は初期位置Ｑ０から変位を開始する（大まかには、未だ、変位されていない初期位置Ｑ０にある）。なお、時修正間欠車５０が回転位置Ｒ３から回転位置Ｒ４まで回る間に、筒車側時修正伝え輪列６の第七時修正伝え車２８をＪ１方向に少し回すので、時修正躍制レバー７０の第七時修正伝え車躍制爪部７３が規正位置から規正解除位置の方に向かう中間位置Ｕ１へとＭ１方向に多少戻される。但し、時修正躍制解除レバー８０が、実際上、初期位置（時修正躍制非解除位置）Ｑ０にあるので、第七時修正伝え車躍制爪部７３による規正は解除されない。なお、筒車側時修正伝え輪列６の第七時修正伝え車２８は筒車１２の第一筒歯車部１２ｃに対して減速結合されているので、筒車筒車１２の（第一筒歯車部１２ｃと一体的な）軸部１２ｄと（運針輪列（図示せず）に直接噛合した）第二筒歯車部１２ｅとの間における軸部１２ｄの歯部１２ｆの一歯分のＮ１方向の相対回転は発生せず、不測のクリック感を与える虞もない。状態Ｓ４において、時修正躍制レバー７０は、円弧状凹部７８で時修正間欠車５０の有歯部５３の先端に当接した状態のままであるので、位置Ｔ３に保たれる。   When the winding stem 30 is further rotated in the C1 direction around the central axis C and reaches the rotational position P4 as shown in FIG. 14, the time correction compound is transmitted via the winding stem side correction transmission wheel train 4. The hour correction drive wheel 40 of the vehicle structure 5 is rotated in the H1 direction, and the hour correction intermittent wheel 50 is adjacent to the inclined surface portion 87 of the engaging claw portion 86 of the hour correction jump release release lever 80 at the side edge 53a of the toothed portion 53. Is engaged and pushed, and the hour correction jump release lever 80 starts to be displaced in the K2 direction. In the state S4 of FIG. 14, the hour correction intermittent wheel 50 reaches the rotational position R4, and the hour correction jump release lever 80 starts to be displaced from the initial position Q0 (roughly, it is still at the undisplaced initial position Q0). is there). While the hour correction intermittent wheel 50 rotates from the rotation position R3 to the rotation position R4, the seventh hour correction transmission wheel 28 of the hour wheel transmission correction wheel train 6 is slightly rotated in the J1 direction. The seventh correction transmission wheel jumping pawl portion 73 of 70 is slightly returned in the M1 direction from the normal position to the intermediate position U1 toward the normal release position. However, since the hour correction jump system release lever 80 is actually in the initial position (time correction jump system non-release position) Q0, the regulation by the seventh hour correction transmission wheel jump control claw portion 73 is not released. Since the seventh correction transmission wheel 28 of the hour correction transmission wheel train 6 is connected to the first cylindrical gear portion 12c of the hour wheel 12 at a reduced speed, the (first cylinder) of the hour wheel 12 N1 direction of one tooth portion of the tooth portion 12f of the shaft portion 12d between the shaft portion 12d (integral with the gear portion 12c) and the second cylindrical gear portion 12e (directly meshed with the needle wheel train (not shown)) The relative rotation does not occur and there is no possibility of giving an unexpected click feeling. In the state S4, the hour correction jump control lever 70 remains in contact with the tip of the toothed portion 53 of the hour correction intermittent wheel 50 at the arc-shaped recess 78, and is thus maintained at the position T3.

巻真３０が、中心軸線ＣのまわりでＣ１方向に更に回転されて、図１５に示したように、回転位置Ｐ５に達すると、巻真側時修正伝え輪列４を介して、時修正複合車構造体５の時修正駆動車４０がＨ１方向に回転され、時修正間欠車５０が有歯部５３の側縁５３ａで時修正躍制解除レバー８０の係合爪部８６の隣接傾斜面部８７を更に押して時修正躍制解除レバー８０をＫ２方向に変位させ、該時修正躍制解除レバー８０を躍制解除位置Ｑ１に設定する。この躍制解除位置Ｑ１では、時修正間欠車５０が有歯部５３の歯５６の先端が時修正躍制解除レバー８０の爪状係合部８６の円弧状凹部８８に当接するようになる。従って、時修正躍制解除レバー８０の腕部８３もＫ２方向に後退するので、時修正躍制レバー作動ピン９０も時修正躍制レバー７０のばね部７２によって押されてＫ２方向に後退する。その結果、時修正躍制レバー７０のばね部７２の先端にある第七時修正伝え車躍制爪部７３もＭ１方向に後退して、第七時修正伝え車２８に対する規正が完全に解除される。この状態Ｓ５では、時修正間欠車５０が回転位置Ｒ５に達して、時修正躍制レバー７０がこのジャンプ位置Ｔ４を採り、時修正間欠車５０のＨ１方向回転に応じて、該間欠車５０の有歯部５３に噛合した第七時修正伝え車２８がＪ１方向に回転するようになり、該車２８のＪ１方向回転に従って、筒車１２の第一筒歯車部１２ｃ及びこれと一体的な軸部１２ｄが第二筒歯車部１２ｅに対してＮ１方向に相対回転するようになり、時針１１ａの回転位置の修正（時修正ないし時差修正）が行われ得るようになる。なお、時修正躍制解除レバー８０がなくても、時修正間欠車５０に加えられるトルクによって第七時修正伝え車２８がばね部７２及び第七時修正伝え車躍制爪部７３からなるジャンパによる規正力に抗して回転され得るけれども、時修正躍制解除レバー８０により第七時修正伝え車躍制爪部７３を完全に後退させておくことにより当該ジャンパ余分な躍制動作をなくす方が好ましい操作感が得られる(時修正の際のクリック感は、筒車１２のところで得られる）。   When the winding stem 30 is further rotated in the C1 direction around the central axis C and reaches the rotational position P5 as shown in FIG. 15, the time correcting composite is transmitted via the winding stem side correction transmission wheel train 4. The hour correction drive wheel 40 of the vehicle structure 5 is rotated in the H1 direction, and the hour correction intermittent wheel 50 is adjacent to the inclined surface portion 87 of the engaging claw portion 86 of the hour correction jump release release lever 80 at the side edge 53a of the toothed portion 53. Is further pressed to displace the corrected jumping release lever 80 in the K2 direction, and the corrected jumping release lever 80 is set to the jumping release position Q1. At the jumping release position Q1, the hour correction intermittent wheel 50 comes to abut the tip of the tooth 56 of the toothed portion 53 against the arcuate recess 88 of the claw-like engaging portion 86 of the hour correction jumping release lever 80. Therefore, the arm portion 83 of the hour correction jump release lever 80 also moves backward in the K2 direction, so that the hour correction jump lever operating pin 90 is also pushed by the spring portion 72 of the hour correction jump control lever 70 and moves backward in the K2 direction. As a result, the seventh correction transmission wheel jump control claw 73 at the tip of the spring portion 72 of the hour correction jump control lever 70 is also retracted in the M1 direction, and the regulation for the seventh correction transmission wheel 28 is completely released. The In this state S5, the hour correction intermittent wheel 50 reaches the rotational position R5, the hour correction jump control lever 70 takes this jump position T4, and the time correction intermittent wheel 50 rotates in the H1 direction according to the rotation of the hour correction intermittent wheel 50. The seventh correction transmission wheel 28 meshed with the toothed portion 53 starts to rotate in the J1 direction. As the wheel 28 rotates in the J1 direction, the first cylindrical gear portion 12c of the hour wheel 12 and the shaft integral therewith. The portion 12d rotates relative to the second cylindrical gear portion 12e in the N1 direction, and the rotational position of the hour hand 11a can be corrected (time correction or time difference correction). Even if the hour correction jump release lever 80 is not provided, a jumper in which the seventh hour correction transmission wheel 28 includes the spring portion 72 and the seventh hour correction transmission wheel jumping pawl portion 73 by the torque applied to the hour correction intermittent wheel 50. Although it can be rotated against the regulation force caused by the time, the jumping movement canceling lever 80 is completely retracted by the hour correcting jump release lever 80 to completely eliminate the jumping action of the jumper. However, a preferable operation feeling can be obtained (a click feeling at the time of correction is obtained at the hour wheel 12).

この後は、図１６に示したように、巻真３０のＣ１方向回転に応じて、時修正間欠車５０の欠歯部５４が第七時修正伝え車２８に対面する回転位相になって時修正間欠車５０の有歯部５３と第七時修正伝え車２８との噛合が解除されるまで、巻真３０のＣ１方向回転が巻真側時修正伝え輪列４を介して時修正複合車構造体５に伝達され、さらに、第七時修正伝え車２８を介して筒車１２の第一筒歯車部１２ｃに伝達されて、時針１１ａが回させられて、時修正すなわち時差修正が行われる。   Thereafter, as shown in FIG. 16, as the winding stem 30 rotates in the C1 direction, the missing tooth portion 54 of the hour correction intermittent wheel 50 becomes a rotation phase facing the seventh hour correction transmission wheel 28. Until the meshing between the toothed portion 53 of the correction intermittent wheel 50 and the seventh hour correction transmission wheel 28 is released, the rotation of the winding stem 30 in the C1 direction via the winding stem side correction transmission wheel train 4 is the hour correction compound vehicle. It is transmitted to the structure 5 and further transmitted to the first cylindrical gear portion 12c of the hour wheel 12 via the seventh hour correction transmission wheel 28, and the hour hand 11a is rotated to correct the time, that is, the time difference. .

以上のような動作における時修正間欠車５０の回転位置の変化と時修正躍制レバー７０の位置と作動ピン９０の位置との関係を大まかに示すと、図１０の通りである。   FIG. 10 schematically shows the relationship between the change in the rotational position of the hour correction intermittent wheel 50 in the above operation, the position of the hour correction jump control lever 70 and the position of the operating pin 90.

以上においては、巻真３０がＣ１方向に回転されて、時針１１ａが時計回り（進む向き）に時差修正が行われる例について説明したけれども、時修正複合車構造体５すなわち該構造体５を構成する時修正駆動車４０及び時修正間欠車５０、並びに時修正躍制レバー７０の躍制爪部７６，７３及び時修正躍制解除レバー８０の係合爪部８６は、回転方向に依存せず対称な形状を有するので、巻真３０がＣ１方向の代わりにＣ２方向に回転されて、時針１１ａが反時計回り）遅れる向き）に時差修正が行われる場合についても、全く同様にそのまま当てはまる。すなわち、この時差修正機構ないし時差修正機構１では、時差を進ませる向きでも遅らせる向きでの全く同様に時差修正が行われ得る。   In the above description, the example in which the winding stem 30 is rotated in the C1 direction and the hour hand 11a is corrected in the clockwise direction (forward direction) has been described. However, the time correcting composite vehicle structure 5, that is, the structure 5 is configured. The hour correction drive wheel 40 and the hour correction intermittent vehicle 50, the jumping claw portions 76 and 73 of the hour correction jump control lever 70, and the engagement claw portion 86 of the hour correction jump release lever 80 do not depend on the rotation direction. Since the winding stem 30 is rotated in the C2 direction instead of the C1 direction and the time difference correction is performed in the direction in which the hour hand 11a is counterclockwise (delayed), since it has a symmetrical shape, the same applies. That is, in the time difference correction mechanism or the time difference correction mechanism 1, the time difference can be corrected in the same manner in the direction in which the time difference is advanced or delayed.

なお、以上においては、時修正複合車構造体５を構成する時修正駆動車４０が係合要素としての円弧状長穴を備え時修正間欠車５０が係合要素としての係合突起（係合ピン）を備える例について説明したけれども、その代わりに、時修正間欠車５０が係合要素としての円弧状長穴を備え時修正駆動車４０が係合要素としての係合突起（係合ピン）を備えていてもよく、その場合も、時差修正機構（時修正機構）は、当然ながら、全く同様に動作し得る。   In the above description, the hour correction drive wheel 40 constituting the hour correction composite vehicle structure 5 has an arc-shaped elongated hole as an engagement element, and the hour correction intermittent wheel 50 is an engagement protrusion (engagement) as an engagement element. However, instead, the hour correction intermittent wheel 50 is provided with an arc-shaped elongated hole as an engagement element, and the hour correction drive wheel 40 is an engagement protrusion (engagement pin) as an engagement element. In this case, the time difference correction mechanism (time correction mechanism) can naturally operate in the same manner.

なお、現時点では請求項に記載の発明の範囲外であるけれども、時修正躍制レバー７０が爪部７６で時修正間欠車５０の有歯部５３，５３及びその間の欠歯部５４に対して躍制動作を行い得る以上、時修正駆動車４０と時修正間欠車５０とが一体回転されるようになっていてもよい。   At this time, although it is outside the scope of the invention described in the claims, the hour correction jump control lever 70 is a claw portion 76 with respect to the toothed portions 53 and 53 of the hour correction intermittent wheel 50 and the toothless portion 54 therebetween. As long as the jumping operation can be performed, the hour correction drive wheel 40 and the hour correction intermittent wheel 50 may be integrally rotated.
