Abstract

<P>PROBLEM TO BE SOLVED: To provide a mechanism which can synchronize a minute hand and a second hand, in a clock which has a mechanism having at least the minute hand and the second hand, and matching the minute hand by a movement. <P>SOLUTION: The mechanism in which the minute hand of the movement is coincided includes a winding stem which can be adjusted to an axial direction between a normal position and an adjusting position. The winding stem is connected with back wheel groups of a day of the movement so as to adjust the minute hand by the rotation of the winding stem when the winding stem is in the adjusting position. Furthermore, the winding stem collaborates with a return-to-zero mechanism. The return-to-zero mechanism moves the second hand to a zero position when the winding stem moves to the adjusting position. During the winding stem is located at the adjusting position, the return-to-zero mechanism stops the second hand at the zero position. When the winding stem is returned to the normal position, the return-to-zero mechanism releases the second hand again. By this, the back wheel groups of the day of the movement have stop mechanisms. This stop mechanism can be stopped at sixty stopping positions. Therefore, by rotating the winding stem at the adjusting position, the minute hand can be adjusted to the head of a certain minute scale between sixty positions of the minute hand. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

本発明は、少なくとも1つの分針、1つの秒針および1つのムーブメントを備え、ムーブメントが分針を合わせる機構を備える時計に関する。この機構は、りゅうずを引き出しまたは押し込むことによって通常位置と調整位置との間で軸方向に調整可能な巻真を含む。巻真は、調整位置にあるとき、巻真の回転によって分針が調整されるように、ムーブメントの日の裏車群と連結する。さらに、巻真は帰零機構と協働し、帰零機構は、巻真を調整位置に動かすとき秒針を帰零させ、巻真が調整位置にある間は、秒針をこのゼロ位置でブロックし、巻真を通常位置に戻すと、秒針を再び解放する。   The present invention relates to a timepiece including at least one minute hand, one second hand, and one movement, and the movement includes a mechanism for aligning the minute hand. This mechanism includes a winding stem that can be adjusted in the axial direction between a normal position and an adjustment position by pulling out or pushing in the crown. When the winding stem is in the adjustment position, the winding stem is connected to the minute wheel group of the movement so that the minute hand is adjusted by the rotation of the winding stem. In addition, the winding stem cooperates with the return zero mechanism, which causes the second hand to return to zero when moving the winding stem to the adjustment position and blocks the second hand at this zero position while the winding stem is in the adjustment position. When the winding stem is returned to the normal position, the second hand is released again.

この種の機構を備える時計は従来技術において既に知られている。例えば、CH18774/71はこのような帰零機構を備えた時計を開示している。時計の時刻合わせのためにりゅうずを引き出すと、秒針はゼロに調整され、りゅうずを押し戻すまでその位置に保持される。   Timepieces with this type of mechanism are already known in the prior art. For example, CH18774 / 71 discloses a timepiece having such a nulling mechanism. When the crown is pulled out to set the time of the watch, the second hand is adjusted to zero and held in that position until the crown is pushed back.

この既知の機構の欠点は、時刻を合わせる過程において秒針と分針の同時性が失われることである。使用者が、りゅうず(巻真は調整位置)を引き出した状態で、りゅうずを回し、それによって巻真を回すと、分針が上に設置された分針筒は、対応する歯車機構を介して回転する。その際、時刻合わせの過程後に、分針が任意の位置、例えば2つの分目盛の真中にあることがある。りゅうずを押し込んだ後、ムーブメントが再び動き始めると、秒針はゼロから動き始めるのに対し、分針は任意の位置から動き始める。したがって、分針と秒針の動きが非同期となる。   The disadvantage of this known mechanism is that the synchronization of the second and minute hands is lost during the time setting process. When the user pulls out the crown (the winding stem is in the adjustment position), the crown is turned, and when the crown is turned, the minute hand cylinder with the minute hand placed on it is connected via the corresponding gear mechanism. Rotate. At that time, after the time setting process, the minute hand may be at an arbitrary position, for example, in the middle of two minute scales. After the crown is pushed in, when the movement starts moving again, the second hand starts moving from zero, while the minute hand starts moving from any position. Therefore, the movements of the minute hand and the second hand are asynchronous.

CH18774/71CH18774 / 71

本発明の課題は、この欠点を克服することである。   The object of the present invention is to overcome this drawback.

この課題は、請求項1のプリアンブルを基礎とし、請求項1の特徴部分によって解決される。   This problem is based on the preamble of claim 1 and is solved by the features of claim 1.

本発明に基づく停止機構は、ムーブメントの日の裏車群に設けられ、60の停止位置が可能である。調整位置にある巻真を回すと、分針筒が動き、それに伴って分針が歩進するが、分針は任意の分目盛から次の分目盛にしか調整できない。つまり分針が2つの分目盛の中間にくることはない。りゅうずを押すと、ムーブメントは再び動き始め、分針は任意の分目盛の頭から、秒針はゼロからスタートし、したがって、両方の針は同期して動く。   The stop mechanism according to the present invention is provided in the minute wheel group of the movement, and 60 stop positions are possible. When the winding stem at the adjustment position is turned, the minute hand cylinder moves and the minute hand advances accordingly. However, the minute hand can be adjusted only from one minute scale to the next minute scale. That is, the minute hand does not come between the two minute scales. When the crown is pressed, the movement starts moving again, the minute hand starts from the head of any minute scale and the second hand starts from zero, so both hands move synchronously.

本発明の有利な実施形態は従属項に記載され、以下の記述で説明する。   Advantageous embodiments of the invention are described in the dependent claims and are explained in the following description.

本発明の特に有利な一実施形態によれば、停止機構は、日の裏車と同心に配設され、内周に60個の停止突部を備えた停止リングと、停止リングの内側に配設され、旋回可能に支承された、少なくとも1つの停止ラッチとを含む。ここでこの停止ラッチは、ばね部材によって径方向外側に突き出され、停止リングの停止突部によってロックされる。りゅうずを引き出した状態で巻真を回すと、停止ラッチに対して停止リングが回転する。停止ラッチは、停止リングの内側に形成された停止突部の形状により、停止ラッチを外側に押すばね部材の力に抗して、その都度径方向内側へ押され、次の停止突部によって再びロックされる。このように、簡単かつ確実に分針の歩進式調整が実現される。   According to a particularly advantageous embodiment of the invention, the stop mechanism is arranged concentrically with the minute wheel and has a stop ring with 60 stop projections on the inner periphery, and is arranged inside the stop ring. And at least one stop latch mounted and pivotally supported. Here, the stop latch protrudes radially outward by the spring member and is locked by the stop protrusion of the stop ring. When the crown is turned with the crown pulled out, the stop ring rotates relative to the stop latch. The stop latch is pushed radially inward each time against the force of the spring member pushing the stop latch outward due to the shape of the stop protrusion formed inside the stop ring, and again by the next stop protrusion. Locked. As described above, the step adjustment of the minute hand can be realized easily and reliably.

好ましくは、停止機構は対称的に配設された2つの停止ラッチを含み、これらの停止ラッチは、その都度、ばね部材のアームによって径方向外側へ突き出される。さらにばね部材は、好ましくは、組立てを簡単にするために二部で形成される。   Preferably, the stop mechanism comprises two symmetrically arranged stop latches, each of which is projected radially outward by the arm of the spring member. Further, the spring member is preferably formed in two parts for ease of assembly.

本発明の特に好ましい一実施形態によれば、帰零機構は、巻真の軸方向の動きによって旋回可能なレバーを含み、このレバーは、巻真を調整位置に動かしたとき、中間車を介して帰零レバーを旋回させ、帰零レバー自体は、秒針を帰零させる帰零作動装置を作動させる。   According to a particularly preferred embodiment of the invention, the nulling mechanism comprises a lever that can be pivoted by the axial movement of the winding stem, which lever is moved via an intermediate wheel when the winding stem is moved to the adjustment position. Then, the nulling lever is turned, and the nulling lever itself operates a nulling operation device that nullifies the second hand.

ここで、旋回可能なレバーは角度レバーであり、歯を備えていることが好ましい。この歯は、中間車の対応する歯と協働できるようになっている。   Here, the pivotable lever is an angle lever, and preferably has teeth. This tooth can cooperate with the corresponding tooth of the intermediate wheel.

好ましくは、中間車は、カム調整面および/または歯を備え、この歯は帰零レバーと協働する。このとき角度レバーの旋回は、まず互いに噛み合った歯を介して中間車に伝達され、中間車は回転運動を行う。この調整面および/または中間車の第2の歯を介して、帰零レバーが旋回する。   Preferably, the intermediate wheel comprises a cam adjustment surface and / or teeth, which cooperate with a nulling lever. At this time, the turning of the angle lever is first transmitted to the intermediate wheel via the meshed teeth, and the intermediate wheel performs rotational movement. The zero return lever pivots through this adjustment surface and / or the second tooth of the intermediate wheel.

帰零レバーはこのとき帰零作動装置を作動させるが、好ましくは、帰零作動装置はハート形の調整カムを含む。秒真とも呼ばれ、秒針の帰零調整をするこのようなハート形の調整カムは従来技術において十分に知られている。   The nulling lever then activates the nulling actuator, but preferably the nulling actuator includes a heart shaped adjustment cam. Such a heart-shaped adjusting cam, which is also referred to as second second and adjusts the return of the second hand to zero, is well known in the prior art.

本発明の好ましい一実施形態によれば、帰零レバーは2つのアームから形成され、第1アームは帰零作動装置を作動させ、第2アームは時計のテンプ輪をストップさせるストップ機構を作動させる。ここで、2つのアームから成るレバーは、好ましくは、りゅうずを引き出した際、帰零作動装置が作動する直前にストップ機構が作動するように形成される。つまり、秒針がムーブメントによって動かされなくなってはじめて、秒針の帰零が行われる。   According to a preferred embodiment of the present invention, the nulling lever is formed of two arms, the first arm activates the nulling actuator and the second arm activates a stop mechanism for stopping the watch balance wheel. . Here, the lever composed of two arms is preferably formed such that when the crown is pulled out, the stop mechanism is actuated immediately before the nulling device is actuated. That is, the second hand is zeroed only when the second hand is not moved by the movement.

本発明の特に有利な一実施形態によれば、帰零レバーは弾性的に形成された領域を備える。2つのアームから成る帰零レバーにおいては、第1アーム、即ち帰零作動装置を作動させるアームを弾性的に形成する場合が特に有利である。弾性があることによって帰零作動装置に作用する力の大きさが適切に調整でき、つまり、確実に帰零調整が達成され、しかも秒車群が損傷を受けない。   According to a particularly advantageous embodiment of the invention, the nulling lever comprises an elastically formed region. In the nulling lever composed of two arms, it is particularly advantageous if the first arm, that is, the arm for operating the nulling actuator is formed elastically. Due to the elasticity, the magnitude of the force acting on the zero return actuator can be appropriately adjusted, that is, the zero return adjustment is reliably achieved, and the second wheel group is not damaged.

分針の調整を力の流れから外すために、ムーブメントの三番車群と秒車群を好ましくは各々二重に実施する。ここで各々、1つ目を香箱とテンプ輪の間で力の流れの中に置き、2つ目を直接または間接的に日の裏車と連結する。   In order to remove the adjustment of the minute hand from the force flow, the third wheel group and the second wheel group of the movement are preferably carried out in duplicate. Here, the first is placed in the flow of force between the barrel and the balance wheel, and the second is connected directly or indirectly to the sun wheel.

さらに詳細には、例えば、ムーブメントの三番車群は、上下に配設され摩擦連結部を介して互いに連結された2つの三番車を含むことができ、第1三番車は日の裏車群と接続され、第2三番車は香箱とテンプ輪の間で力の流れの中に置かれる。同様に、ムーブメントの秒車群は、上下に配設され摩擦連結部を介して互いに連結された2つの秒車を含むことができ、第1秒車は帰零作動装置と接続されるとともに、三番車群を介して日の裏車群と接続され、第2秒車は香箱とテンプ輪の間で力の流れの中に置かれる。巻真が通常位置にあるときは、摩擦連結部を介して連結された2つの三番車と2つの秒車はそれぞれ一緒に動く。巻真が調整位置にあるときは、秒針を帰零させるために、帰零作動装置を介して第1秒車が回転する。同時に、ストップ機構がテンプ輪をストップさせ、それによって力の流れをストップさせる。秒車群と三番車群の帰零作動装置と動作可能に結合されている半分はそれぞれ、力の流れの中にある他の半分に対して動くだけである。   More specifically, for example, the third wheel group of the movement may include two third wheel wheels arranged one above the other and connected to each other via a friction connecting portion. Connected to the car group, the second wheel No. 3 is placed in the force flow between the barrel and the balance wheel. Similarly, the second wheel group of the movement can include two second wheels arranged one above the other and connected to each other via a friction coupling portion, and the first second wheel is connected to the zero return actuator, The second wheel is connected in the flow of power between the barrel and the balance wheel through the third wheel group and connected to the minute wheel group. When the winding stem is in the normal position, the two third wheel and the second wheel connected via the frictional connection part move together. When the winding stem is in the adjustment position, the first second wheel is rotated via the zero return operating device in order to return the second hand to zero. At the same time, the stop mechanism stops the balance wheel, thereby stopping the force flow. The halves that are operatively associated with the second wheel and third wheel group zero return actuators each move only relative to the other half in the force flow.

りゅうずを押し戻すと、帰零調整作動装置とテンプ輪は再び解放される。その際、摩擦連結部により、本発明の機構のおかげで同期された秒針と分針はあがきを生ずることなく動き始めることができる。   When the crown is pushed back, the zero return adjusting device and the balance wheel are released again. In this case, the frictional connection allows the synchronized second and minute hands to start moving without any striking thanks to the mechanism of the invention.

以下、本発明の好ましい実施形態を添付の図面に基づいて説明する。   Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

FIG.

図1は、本発明に基づく時計のムーブメントの一部分の斜視図である。同じムーブメントが、図2Aおよび3Aでは側面図で、図2Bおよび3Bでは上面図で示されている。巻真16は、図2Aおよび2Bにおいても図1と同様に、通常位置にあり、これに対し、図3Aおよび3Bでは軸方向外側の調整位置に調整されている。図1、図2Aおよび図2Bのように巻真16が通常位置にある場合は、ムーブメントは通常通り作動する。ムーブメントの各機能は当業者には十分周知であり、本発明の対象ではないので、ここでは詳細に説明しない。以下で詳細に説明しない参照番号の意味については、後述する「符号の説明」に示す。   FIG. 1 is a perspective view of a portion of a timepiece movement according to the present invention. The same movement is shown in side view in FIGS. 2A and 3A and in top view in FIGS. 2B and 3B. The winding stem 16 is also in the normal position in FIGS. 2A and 2B as in FIG. 1, whereas in FIGS. 3A and 3B, it is adjusted to the adjustment position on the axially outer side. When the winding stem 16 is in the normal position as shown in FIGS. 1, 2A and 2B, the movement operates normally. Each function of the movement is well known to those skilled in the art and is not the subject of the present invention, so it will not be described in detail here. The meanings of reference numerals not described in detail below will be described in “Explanation of Symbols” described later.

特に図2Aおよび3Aの側面図から分かるように、このムーブメントの三番車群34は、互いに上下に配置され、皿ばね35を介して互いに連結された2つの三番車34a、34bを含む。上側三番車34aは、日の裏車群40と結合するのに対して、下側三番車34bは、香箱10とテンプ輪26の間で力の流れの中にある。   As can be seen particularly from the side views of FIGS. 2A and 3A, the third wheel group 34 of this movement includes two third wheel wheels 34 a and 34 b which are arranged one above the other and connected to each other via a disc spring 35. The upper third wheel 34 a is connected to the minute wheel group 40, while the lower third wheel 34 b is in a force flow between the barrel 10 and the balance wheel 26.

ムーブメントの秒車群32も同様に、二部で実施される。この場合も、秒車32aを備えた下側部分は、香箱10とテンプ輪26の間で力の流れの中にある。同様に、この下側秒車32は、摩擦連結部、例えば皿ばねまたは引張ばねを介して上側秒車32bと連結されており、上側秒車32bは帰零ハートカム32cおよび秒車軸32dと回転不能に結合されている。秒車群の上側部分、即ち上側秒車32b、帰零ハートカム32cおよび秒車軸32dは三番車群34を介して日の裏車群40と結合されている。   The second wheel group 32 of the movement is also implemented in two parts. Also in this case, the lower part provided with the second wheel 32 a is in a force flow between the barrel 10 and the balance wheel 26. Similarly, the lower second wheel 32 is connected to the upper second wheel 32b via a friction connecting portion, for example, a disc spring or a tension spring, and the upper second wheel 32b cannot rotate with the zero return heart cam 32c and the second wheel shaft 32d. Is bound to. The upper part of the second wheel group, that is, the upper second wheel 32b, the zero return heart cam 32c, and the second wheel shaft 32d are coupled to the minute wheel group 40 via the third wheel group 34.

りゅうずが押し込まれた状態では、中間車20の歯20Aが角度レバー18の歯18aと噛合することによって、角度レバー18は歯18aで中間車20を保持する。中間車20は、第2の歯20bを介して帰零レバー22を保持している。 ここでは、帰零レバー22の歯22aが、中間車の第2の歯20bと噛合している。帰零レバー22は帰零アーム22bとストップアーム22cとに分けられ、図3Bを見るとその機能が良く理解できる。巻真16が通常位置にあるときは、2つのアーム22b、22cは、それぞれニュートラル位置に保持される。   In a state where the crown is pushed in, the teeth 20A of the intermediate wheel 20 are engaged with the teeth 18a of the angle lever 18, so that the angle lever 18 holds the intermediate wheel 20 with the teeth 18a. The intermediate wheel 20 holds a zero return lever 22 via the second teeth 20b. Here, the teeth 22a of the zero return lever 22 mesh with the second teeth 20b of the intermediate wheel. The nulling lever 22 is divided into a nulling arm 22b and a stop arm 22c, and its function can be well understood by referring to FIG. 3B. When the winding stem 16 is in the normal position, the two arms 22b and 22c are each held in the neutral position.

りゅうずを引き出すと、即ち、巻真16をその調整位置にすると(図3Aおよび3Bを参照)、角度レバー18が旋回し、次いで歯18aを介して同じく歯付きの中間車20を回転させる。第2の歯20bおよび調整面20cを介して、中間車20は帰零レバー22を旋回させる。これによって、帰零レバー22の帰零アーム22bが、秒車群32の一部である帰零ハートカム32cに押し付けられ、秒針を備えた秒車軸32dがゼロ位置に移動し、その位置で固定される。   When the crown is pulled out, that is, when the winding stem 16 is in its adjusted position (see FIGS. 3A and 3B), the angle lever 18 turns and then the toothed intermediate wheel 20 is also rotated through the teeth 18a. The intermediate wheel 20 turns the zero return lever 22 via the second teeth 20b and the adjustment surface 20c. As a result, the zero return arm 22b of the zero return lever 22 is pressed against the zero return heart cam 32c which is a part of the second wheel group 32, and the second wheel shaft 32d provided with the second hand moves to the zero position and is fixed at that position. The

同時に、帰零レバー22のストップアーム22cは、帰零ハートカム32cの作用領域に達する直前にブレーキレバー23を解放し、ブレーキレバー23はブレーキばね24を解放し、次いでブレーキばね24はテンプ輪26をストップし、それによってムーブメントをストップする。   At the same time, the stop arm 22c of the zero return lever 22 releases the brake lever 23 just before reaching the operating region of the zero return heart cam 32c, the brake lever 23 releases the brake spring 24, and then the brake spring 24 releases the balance wheel 26. Stop and thereby stop the movement.

帰零レバー22の帰零アーム22bは比較的薄く、したがって弾性的に形成される。帰零アーム22bが帰零ハートカム32cに作用する力の大きさが、その弾性によって決まり、帰零アーム22bの正確な形状、したがって弾性力は、この図面では図示しない秒針の帰零が確実に機能するが、秒車群32は損傷しないように選択される。中間車20と帰零レバー22の間に特別に配設された歯20b、20aにより、帰零アーム22bのばね力によって生成される回転モーメントは角度レバー18に伝達されない。したがって、巻真16を、それに伴ってりゅうずを、巻真16が自律的に再び通常位置に戻ってしまうことなく、時刻を合わせるために問題なく回すことができる。   The nulling arm 22b of the nulling lever 22 is relatively thin and thus elastically formed. The magnitude of the force that the nulling arm 22b acts on the nulling heart cam 32c is determined by its elasticity, and the exact shape of the nulling arm 22b, and hence the elastic force, ensures that the nulling of the second hand, not shown in this drawing, functions. However, the second wheel group 32 is selected so as not to be damaged. The rotation moment generated by the spring force of the zero return arm 22 b is not transmitted to the angle lever 18 by the teeth 20 b and 20 a specially arranged between the intermediate wheel 20 and the zero return lever 22. Therefore, the winding stem 16 can be rotated without any problem in order to set the time without the winding stem 16 autonomously returning to the normal position again.

巻真16が回転するとき、図示しない分針は分針筒43の周りを回転する。その際、巻真16の回転は、周知のようにして、対応する歯車機構(とりわけ換え歯車36)を介して分針筒43に伝達される。図4A、4Bおよび4Cで明確に認められる、日の裏車群40の停止機構により、この動きをある分目盛から次の分目盛へと歩進式に行うことができる。図4A、4Bおよび4Cに示されるように、停止リング44が設けられ、停止リング44は日の裏車42と同心であり、停止リング44の外周の直径は、外周に歯が刻まれた日の裏車42の直径より僅かに小さい。停止リングは分針筒43と回転不能に結合され(図4B参照)、その内周に停止突部45が60個設けられている。これらの停止突部45は2つの停止ラッチ46と協働して、60の位置を採りうる分針筒43の位置を決定し、それによって分針の位置を決定する。両方の停止ラッチ46は、それぞれ日の裏車42上の軸受47に旋回可能に支承されている。組立てを簡単にするために二部で形成され、日の裏車42の中央に設置される引張ばね48が、2つの停止ラッチ46の、軸受47とは反対側の端部を外側に押し、それにより、2つの停止ラッチ46は、それぞれ、接触面46aにおいて停止リング44の停止突部45に接触する。   When the winding stem 16 rotates, a minute hand (not shown) rotates around the minute hand cylinder 43. At this time, the rotation of the winding stem 16 is transmitted to the minute hand cylinder 43 through a corresponding gear mechanism (in particular, the change gear 36) as is well known. The stop mechanism of the minute wheel group 40, clearly seen in FIGS. 4A, 4B and 4C, allows this movement to be stepped from one minute scale to the next. As shown in FIGS. 4A, 4B and 4C, a stop ring 44 is provided, the stop ring 44 is concentric with the minute wheel 42, and the diameter of the outer periphery of the stop ring 44 is the day on which the teeth are carved on the outer periphery. It is slightly smaller than the diameter of the back wheel 42 of the car. The stop ring is non-rotatably coupled to the minute hand cylinder 43 (see FIG. 4B), and 60 stop protrusions 45 are provided on the inner periphery thereof. These stop protrusions 45 cooperate with the two stop latches 46 to determine the position of the minute hand cylinder 43 that can take the position of 60, thereby determining the position of the minute hand. Both stop latches 46 are pivotally supported by bearings 47 on the minute wheel 42 respectively. A tension spring 48 formed in two parts for ease of assembly and installed in the center of the minute wheel 42 pushes the end of the two stop latches 46 opposite the bearing 47 outward, Thereby, the two stop latches 46 contact the stop protrusion 45 of the stop ring 44 at the contact surface 46a, respectively.

りゅうずが引き出された状態で巻真16を回すと、換え歯車36を介して分針筒43を停止リング44と結合し、換え歯車36を巻真16と連結する歯車機構が、日の裏車42に対してその停止ラッチ46を回す。帰零ハートカム32cはブロックされているので、このとき、日の裏車42は三番車群34によってブロックされる(図3Aおよび3B参照)。その際、停止ラッチ46は、停止突部45により、ばね部材48が外側に押す力に対して、径方向内側に押され、接触面46aにおいて、それぞれの停止突部45に沿って滑り、その結果、分針筒が停止ラッチ46を再び次の停止突部45によってロックするまでに、分針筒は60分の1回転する。これによって分針を、ある分目盛から次の分目盛へと歩進式に調整することができる。   When the winding stem 16 is turned with the crown pulled out, a gear mechanism for connecting the minute hand cylinder 43 to the stop ring 44 via the change gear 36 and connecting the change gear 36 to the winding stem 16 is provided on the reverse side of the vehicle. The stop latch 46 is rotated with respect to 42. Since the return zero heart cam 32c is blocked, the minute wheel 42 is blocked by the third wheel & pinion group 34 (see FIGS. 3A and 3B). At that time, the stop latch 46 is pushed radially inward by the stop protrusion 45 against the force of the spring member 48 pressing outward, and slides along the stop protrusion 45 on the contact surface 46a. As a result, the minute hand cylinder makes 1 / 60th rotation until the minute hand cylinder locks the stop latch 46 by the next stop protrusion 45 again. As a result, the minute hand can be adjusted step by step from one minute scale to the next minute scale.

りゅうずを押し、それによって巻真16を再び通常位置にすると(図1、2Aおよび2B参照)、角度レバー18は中間車20を動かす。中間車20と帰零レバー22の間で歯20b、22aが噛合することによって、帰零レバー22は再びニュートラルな初期位置に戻される。帰零レバー22の帰零アーム22bは、秒車群32上の帰零ハートカム32cを再び解放する。同時に、帰零レバー22のストップアーム22cによってブレーキレバー23も同様にニュートラル位置に戻され、ブレーキばね24はテンプ輪26から外れ、それによりテンプ輪26が再び解放され、ムーブメントが再び動き始める。   When the crown is pushed, thereby bringing the winding stem 16 back to the normal position (see FIGS. 1, 2A and 2B), the angle lever 18 moves the intermediate wheel 20. When the teeth 20b and 22a are engaged between the intermediate wheel 20 and the zero return lever 22, the zero return lever 22 is returned to the neutral initial position again. The zero return arm 22b of the zero return lever 22 releases the zero return heart cam 32c on the second wheel group 32 again. At the same time, the brake lever 23 is similarly returned to the neutral position by the stop arm 22c of the return lever 22, the brake spring 24 is released from the balance wheel 26, whereby the balance wheel 26 is released again, and the movement starts to move again.

摩擦連結部は、2つの三番車34a、34bならびに秒車群の上側部品(32b、32c、32d)および下側部品(32a)を互いに連結するが、この摩擦連結部によって、分針と秒針はあがきを生ずることなく動き始めることができる。このとき、秒針が帰零機構によってゼロから動き始めるのに対し、分針は停止機構によって分目盛の頭から動き始める。このようにして2つの針は同期して動く。   The frictional connection part connects the two third wheel 34a, 34b and the upper part (32b, 32c, 32d) and the lower part (32a) of the second wheel group, but the minute hand and the second hand are connected by this frictional connection part. You can start moving without creating agitation. At this time, the second hand starts to move from zero by the zero return mechanism, whereas the minute hand starts to move from the head of the minute scale by the stop mechanism. In this way, the two needles move synchronously.
