【考案の詳細な説明】
本考案は時計の指針秒針帰機構の改良に関し、
特に、秒針規制（帰零）操作が時刻修正の際に修

きることを特徴とする。[Detailed description of the invention] This invention relates to the improvement of the second hand return mechanism of a watch.
In particular, in addition to the second hand regulation (return to zero) operation that is performed when the correction axis is operated when adjusting the time, it is impossible to operate the second hand return to zero using the correction axis using an operating lever located outside the watch mechanism. The present invention is characterized in that the operating lever can be set to enable only the return of the second hand to zero, other than correction of the hour and minute hands.
従来、時計の指針修正機構には修正軸にテーパ
ー面を有する規正カムが固着され、該修正軸の修
正方向移動に伴い前記規正カムが秒針規制を行な
うと共に、この状態にて修正軸を回転し時分針の
修正を果たす機構が周知である。 Conventionally, in the pointer adjustment mechanism of a watch, a regulation cam having a tapered surface is fixed to a correction shaft, and as the correction shaft moves in the correction direction, the regulation cam regulates the second hand, and in this state, the correction shaft is rotated. Mechanisms for correcting the hour and minute hands are well known.

い。つまり、使用者は秒針等の停止あるいは帰零
を行なう場合、又は、時分針の修正に行なう場合
において極めて強く修正軸を引かなければなら
ず、操作性を損なうものであつた。 In this correction mechanism, a return spring is attached to the regulating body so that the regulating body does not interfere with the timing operation of the timepiece wheel train when the regulating body is not corrected. Further, a return spring is attached to the correction shaft so that the engagement between the watch wheel train and the correction pinion is released when the correction shaft is not corrected. Therefore, when the user wants to correct the pointer, he or she must operate against the return forces of the two return springs, one on the body and one on the correction shaft. In other words, the user has to pull the correction shaft extremely hard when stopping or returning the second hand, etc., or when correcting the hour and minute hands, which impairs operability.
また、指針修正と指針規制が１個の修正軸にて
連動される修正機構では、指針規制のみを行なう
場合でも修正カナと表示車は一担伝動可能に噛合

秒針規制における不具合解消が強く望まれてい
る。 In addition, with a correction mechanism in which pointer correction and pointer regulation are linked by a single correction shaft, even when only pointer regulation is performed, the correction kana and the display wheel are meshed for one-way transmission, so the hour and minute hands are incorrectly corrected. There were also problems caused by this. In recent years, the precision of electronic watches having crystal oscillators has been significantly improved, and there are more opportunities to adjust the second hand than to adjust the hour and minute hands. Therefore, it is strongly desired to resolve the problem with the second hand regulation.
本考案は上記の問題を解消するためになされた
ものであり、その目的は、秒針帰零が指針修正軸
による時刻修正操作時に行えると共に、指針修正
軸以外の操作レバーにて時刻修正輪列と全く関係

構を提供することである。 The present invention was made to solve the above problems, and its purpose is to allow the second hand to return to zero when adjusting the time using the pointer adjustment shaft, and to also enable the time adjustment wheel train to be adjusted using an operating lever other than the pointer adjustment shaft. To provide a pointer correction mechanism capable of only returning the second hand to zero without any involvement.

る。 In order to achieve this purpose, the present invention provides a pointer correction mechanism in which the second hand returns to zero by bringing a regulating body swingably supported on a receiving plate into contact with a heart cam provided at the fourth stem. In the vicinity of the time adjustment shaft, an operating body is provided that is rotatable and movable in the axial direction on a receiving plate, etc., and is pivotally supported so that it can be selectively held at a predetermined position in the axial direction. has a first part that can be engaged with the correction shaft when the correction shaft is operated to correct the time.
A second operating lever is always engaged with the operating lever by a regulating body and a return force applied to the regulating body, and presses and moves the regulating body in the direction of the heart cam when the second hand returns to zero. A third operation that is exposed outside the mechanism and that can be selectively placed in a position where the first operation lever can be engaged with the correction shaft or a position where it cannot be engaged with the correction shaft when the first operation lever is operated by an external operation to correct the time of the correction shaft. When a lever is provided and the first operating lever is placed in a position where it cannot engage with the correction shaft due to external operation of the third operating lever, the third operating lever can be rotated manually. The feature is that the second hand returns to zero only when the watch is turned.

は従来よりも弱くてよく、操作性は向上する。 Next, the operation of the above embodiment will be explained. FIG. 1 shows a state in which the second hand regulation is set to be interlocked with the correction shaft 14, and the third operating lever 38 is located at the C position shown in FIG. In this state, when the correction shaft 14 is pulled in the direction of the arrow X in FIG. Rotate. The correction pinion 12 and the correction transmission wheel (not shown) are engaged with each other so that the hour and minute hands can be corrected, and
The second operating lever 36 of the operating body 26 presses and moves the regulating lever 48 of the regulating body 46, and as is well known, the regulating portion 50 comes into contact with the heart cam 44, thereby regulating the second hand. In addition, in FIG. 1, the third operating lever 38 of the operating body 26 is operated externally to
By moving from position C to position D in the diagram,
The regulating body 46 can be adjusted without any operation of the correction shaft 14.
can only be operated. Since the operating force acting on the operating body 26 is applied at a position relatively far from the axial center of the operating body 26, even if the return force of the return spring 52 biased by the regulating body 46 is strong, the operating force is extremely small. Can be operated. Furthermore, the correction shaft 14 is directly connected to the regulating body 46.
Since the second hand is controlled via the operating body 26 rather than being moved in a plane, the friction between the regulating body 46 and the adjusting cam fixed to the adjusting shaft 14, which conventionally occurs, is also reduced. As a result, when the second hand regulation is performed in conjunction with the hour and minute hand correction, the operating force of the correction shaft 14 may be weaker than in the past, and the operability is improved.

ように規制体４６を可動させて行なう。 Next, a case will be described in which only the hour and minute hands are corrected without regulating the second hand. When the third operation lever 38 shown in FIG. 1 is moved from the C position to the E position shown in FIG. The operating body 26 is engaged with the locking groove 32b and moves in the direction of arrow A. The first operating lever 34 of the operating body 26 and the collar portion 10 of the correction shaft 14 are set in a completely non-overlapping state. In this state, when the correction shaft 14 is pulled in a well-known manner, the correction pinion 12 and the correction transmission wheel (not shown) are engaged, and only the hour and minute hands are corrected. The restoring force applied to the correction shaft 14 is only the restoring spring 24 shown in FIG. In this state, in order to control the second hand, the third
This is possible by externally operating the operating lever 38. In other words, as shown in FIG.
By moving directly from the E position to the F position, the operating body 26 is rotated in the Z direction in FIG. 2, and the regulating body 46 is moved as described above.

However, by fixing another disk having teeth, it is possible to create a structure in which the second hand is stopped by extremely simple modification of the operating body 26.

段に向上するという効果がある。 As described in detail above, according to the present invention, the user can easily change the pointer correction mode as desired by an extremely simple operation. Further, the operating body 26 that transmits the second hand regulation operation can provide a large operating force with an extremely small force based on the so-called lever principle, so that the operational load can be reduced. Furthermore, since the second hand can be regulated independently of the correction axis, the problem that the hour and minute hands are erroneously corrected when the second hand is regulated (returns to zero) is eliminated. Furthermore, when the present invention is used in a wall clock, the pointer correction form can be easily changed between when the wall clock is hung on a wall, etc., and when it is removed from the wall and held at hand, and its operability is improved. It has the effect of significantly improving it.
