Description

【0001】
【発明の属する技術分野】
本発明は、時刻修正のための針合わせを行う時計に関する。
【0002】
【従来の技術】
巻真とつづみ車と小鉄車とを有する時計の切換構造において、巻真の引出しにより、おしどりとかんぬきを介して、つづみ車を巻真の軸方向に移動させて、針合わせ輪列とつづみ車を噛み合わせる時計の切換構造が従来から知られている。この時計の切換構造は、つづみ車を巻真の軸方向に移動させるために、おしどり、かんぬき等の部品を介して行う複雑な機構を有するものであり、また、つづみ車がスライドするストロークとかんぬき等の引掛け部が必要なためにムーブメントの外径も大きくなるという問題がある。
【0003】
上記の問題を解決する時計の切換構造が、特許文献1に開示されている。即ち図5と図6に示す如く、巻真とつづみ車と小鉄車とを有する時計の切換構造において、つづみ車移動部材によってつづみ車を上下に移動させ、つづみ車と針合わせ輪列の小鉄車と噛合わせたり噛合いを外したりする切換構造である。この従来の時計の切換構造においては、巻真1が地板2に摺動可能に保持され、バネ部材3の貫通穴には巻真1のソロバン玉1a部が引掛けられている。ソロバン玉1a部と巻真角部1cの間には、つづみ車4が案内されている。つづみ車4の外周と地板2の間には、板バネ14又はコイルバネ15が配置されている。
【0004】
図5の通常運針時の巻真1を押し込んだ状態では、巻真角部1cが地板2の横穴2aに逃げ、板バネ14又はコイルバネ15が、つづみ車4を常に小鉄車5から遠ざける方向へ押しつけている。このため、つづみ車4の歯4aと小鉄車5は噛合わず、他の輪列は通常の運針を行っている。図6の針合わせ時の巻真1を一段引いた状態では、巻真角部1cが地板2の横穴2aに逃げ、板バネ14又はコイルバネ15が、つづみ車4の内周角穴に噛合い、板バネ14又はコイルバネ15は押し下げられ、つづみ車4の歯4aと小鉄車5が噛合い、巻真1を回すことにより時刻修正ができる。
【0005】
特許文献1に開示されている時計の切換構造は、かんぬきを用いないで、つづみ車移動部材でつづみ車と小鉄車を噛み合わせたり外したりできる構造である。つづみ車が巻真の軸方向にスライドしないこと、及びつづみ車にかんぬきなどの引掛け部を設けなくても済むのでつづみ車の長さが短くなることから、ムーブメント外径を小さくできるという効果を奏するものである。しかしながら、この従来の時計の切換構造はつづみ車移動部材を備えるものであるから、まだ構成が複雑であるという問題がある。また、通常運針時も小鉄車は針合わせ輪列に噛合っているので、針合わせ輪列の負荷がその分だけ大きいという問題もある。

【0007】
【発明が解決しようとする課題】
本発明が解決しようとする課題は、巻真とつづみ車と小鉄車とを有する時計において、かんぬきは勿論のこと、つづみ車移動部材を用いない簡単な切換構造の時計を提供することである。
【0008】
【課題を解決する手段】
上記課題を解決する時計を、通常運針時位置と時刻修正時位置の少なくとも2つの軸方向位置に位置決めされるようにして地板に取り付けられた巻真と、巻真の角部と噛合う内周角穴が形成されたつづみ車と、前記巻真が通常運針時位置に位置づけられたときには上位置に保持され且つ前記巻真が時刻修正時位置に位置づけられたとき下位置に移動させられる小鉄車とで構成した。そして、前記小鉄車を、前記上位置にあるときは前記つづみ車と針合わせ輪列との噛合いを夫々外され、また前記下位置にあるときは前記つづみ車と針合わせ輪列と夫々噛合うように地板に取り付けた。
【0009】
上述の時計において、前記小鉄車は回転軸を有するものであって、前記小鉄車はその上側回転軸が輪列受に形成された案内穴に案内され且つその下側回転軸が地板に形成された案内穴に案内されて上下移動可能に支持され、更に、前記小鉄車はバネによって下向きに弾性力が印加されていることを特徴とするものである。
【0010】
また、上述の時計において、前記小鉄車は中心に案内穴が外周部に下方に突き出たクラッチピンが形成されたものであって、前記小鉄車は地板に固定された回転軸に前記案内穴を貫通し且つ前記クラッチピンを地板に形成された案内穴を貫通させて上下移動可能に支持され、更に前記小鉄車はバネによって下向きに弾性力が印加されていることを特徴とするものである。
【0011】
【発明の実施の形態】
本発明の第1実施形態の時計は、通常運針時における断面図である図1と時刻修正時における断面図である図2に示す如く、通常運針時位置と時刻修正時位置の少なくとも2つの軸方向位置に位置決めされるようにして地板2に取り付けられた巻真1と、巻真1の角部1cと噛合う内周角穴が形成されたつづみ車4と、巻真1が通常運針時位置に位置づけられたときには上位置に保持され且つ巻真1が時刻修正時位置に位置づけられたときに下位置に移動させられる上下移動可能な小鉄車5とを有する時計である。
【0012】
上下移動可能な小鉄車5は、前記上位置にあるときはつづみ車4との噛合いと日の裏車6との夫々の噛合いを外され、また前記下位置にあるときはつづみ車4と日の裏車6と夫々噛合うように地板2に取り付けられている。
【0013】
即ち、図1及び図2に示す上下移動可能な小鉄車5は、つづみ車4と噛合う歯5aと、上側回転軸5bと下側回転軸5cからなる回転軸とを有する。小鉄車5の上側回転軸5bは輪列受11に形成された案内穴11aに案内され且つその下側回転軸11cが地板2に形成された案内穴2aに案内されて上下移動可能に支持されている。更に、小鉄車5は小鉄車押えバネ16によって下向きに弾性力が印加されている。
【0014】
図1と図2に示す小鉄車押えバネ16は、小鉄車5の上側回転軸5bの端部を上から押える板バネである。この板バネは電池のプラス端子等のバネ部品を利用して形成できる。しかしながら、小鉄車に下向きの弾性力を印加する部材は、図1と図2に示す板バネの小鉄車押えバネ16に限定されるものではない。例えば、小鉄車5の上面と対向する輪列受11の下面との間に配置した板バネ又はコイルバネも小鉄車押えバネ16として利用できる。
【0015】
以上説明した第1実施形態の時計において、巻真1が押し込まれた通常運針時位置にあるときには、図1に示す如く、巻真1の先端の円柱部は小鉄車5の下側回転軸5cに入り込み、小鉄車5は上位置に押し上げられる。すると、小鉄車5はつづみ車4との噛合いを外され、時計は通常運針状態となる。この場合、小鉄車5は日の裏車6との噛合いも外されるから、その分だけ、針回し輪列の負荷が減る。
【0016】
巻真1が一段引き抜かれた時刻修正時位置にあるときには、図2に示す如く、巻真1の先端は小鉄車5の下側回転軸5cから完全に離れるから、小鉄車5は小鉄車押えばねの弾性によって下位置に押し下げられる。すると、小鉄車5はつづみ車4と日の裏車6とに噛合い、巻真1からつづみ車4、つづみ車4から小鉄車5、小鉄車5から日の裏車6の順に、巻真1から針回し輪列へ回転力が伝達可能な状態、即ち時刻修正状態となる。
【0017】
次に、本発明の第2実施形態の時計は、通常運針時における断面図である図3と時刻修正時における断面図である図4に示す如く、通常運針時位置と時刻修正時位置の少なくとも2つの軸方向位置に位置決めされるようにして地板2に取り付けられた巻真1と、巻真1の角部1cと噛合う内周角穴が形成されたつづみ車4と、巻真1が通常運針時位置に位置づけられたときには上位置に保持され且つ巻真1が時刻修正時位置に位置づけられたとき下位置に移動させられる上下移動可能な小鉄車5とを有する時計である。
【0018】
上下移動可能な小鉄車5は、前記上位置にあるときはつづみ車4と針合わせ輪列との夫々の噛合いを外され、また前記下位置にあるときはつづみ車4と日の裏車6と夫々噛合うように地板2に取り付けられている。
【0019】
即ち、図3及び図4に示す上下移動可能な小鉄車5は、つづみ車4と噛合う歯5aと、中心部に穿たれた案内穴5dを有する。またクラッチピン17は小鉄車5と地板2の間に位置し、3/4以上の環状部分と下方に突き出した形状を有する。小鉄車5は地板2に固定された固定回転軸2bを案内穴5dに貫通させる。またクラッチピン17を地板2に形成された案内穴2cを貫通させて上下移動可能に支持されている。更に、小鉄車5は小鉄車押えバネ16によって下向きに弾性力が印加されている。
【0020】
図3と図4に示す小鉄車押えバネ16は、小鉄車5の上面を上から押える板バネであるが、コイルバネでもよい。
【0021】
以上説明した第2実施形態の時計の切換構造において、巻真1が押し込まれた通常運針時位置にあるときには、図3に示す如く、巻真1の先端の円柱部はクラッチピン17の下側に入り込み、クラッチピン17と小鉄車5は上位置に押し上げられる。すると、小鉄車5はつづみ車4との噛合いを外され、時計は通常運針状態となる。この場合、小鉄車5は日の裏車6との噛合いも外されるから、その分だけ、針回し輪列の負荷が減る。
【0022】
巻真1が一段引き抜かれた時刻修正時位置にあるときには、図4に示す如く、巻真1の先端はクラッチピン17から完全に離れるから、小鉄車5は小鉄車押えばねの弾性によって下位置に押し下げられる。すると、小鉄車5はつづみ車4と日の裏車6とに夫々噛合い、巻真1からつづみ車4、つづみ車4から小鉄車5、小鉄車5から日の裏車6の順に、巻真1から針回し輪列へ回転力が伝達可能な状態、即ち時刻修正状態となる。
【0023】
【発明の効果】
本発明は、巻真が通常運針時位置に位置づけられたときには上位置に保持され且つ前記巻真が時刻修正時位置に位置づけられたとき下位置に移動させられる小鉄車とを有する時計の切換構造であるから、従来の時計の切換構造と異なり、かんぬき、おしどり等の部品を用いない簡単な構成の時計の切換構造を提供することができた。
【0024】
また、本発明に係る時計の切換構造においては、巻真が通常運針時位置に位置づけられたときには小鉄車と針合わせ輪列との夫々の噛合が外れるので、その分だけ針回し輪列の負荷が減り、運針用モータの消費電流を低減できるようになった。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a timepiece for adjusting hands for time correction.
[0002]
[Prior art]
In a switching structure of a timepiece having a winding stem, a pinwheel, and a small iron wheel, by pulling out the winding stem, the stroller is moved in the axial direction of the winding stem via a setting lever and a bolt, and the hand setting wheel train and 2. Description of the Related Art A switching structure of a timepiece that meshes with a ratchet wheel has been conventionally known. The switching structure of the timepiece has a complicated mechanism for moving the stroller in the axial direction of the winding stem through a component such as a setting lever, a bolt, and the like. There is a problem that the outer diameter of the movement becomes large because a hook portion such as a bolt is required.
[0003]
A timepiece switching structure that solves the above problem is disclosed in Patent Document 1. That is, as shown in FIGS. 5 and 6, in a timepiece switching structure having a winding stem, a stroller and a small iron wheel, the stroller wheel is moved up and down by a stroller moving member so that This is a switching structure that meshes with and disengages from a row of small iron wheels. In this conventional switching structure of a timepiece, the winding stem 1 is slidably held on the main plate 2, and a through-hole of the spring member 3 is hooked by a solo van ball 1 a of the winding stem 1. A continuous wheel 4 is guided between the solo ban ball 1a and the winding true corner 1c. A leaf spring 14 or a coil spring 15 is disposed between the outer periphery of the wheel 4 and the main plate 2.
[0004]
In the state where the winding stem 1 is pushed in at the time of the normal hand operation in FIG. 5, the winding true corner portion 1c escapes to the side hole 2a of the main plate 2, and the leaf spring 14 or the coil spring 15 moves the pinwheel 4 away from the small iron wheel 5 at all times. It is pushing to. For this reason, the teeth 4a of the continuous wheel 4 and the small wheel 5 do not mesh with each other, and the other wheel trains perform normal hand movement. In the state where the winding stem 1 at the time of needle setting in FIG. 6 is pulled down by one step, the winding true corner portion 1c escapes to the side hole 2a of the main plate 2, and the leaf spring 14 or the coil spring 15 meshes with the inner peripheral square hole of the pinwheel 4. The leaf spring 14 or the coil spring 15 is pushed down, the teeth 4a of the pinwheel 4 mesh with the small wheel 5, and the time can be adjusted by turning the winding stem 1.
[0005]
The switching structure of a timepiece disclosed in Patent Literature 1 is a structure in which a stroller wheel and a small iron wheel can be engaged or disengaged by a stroller moving member without using a bolt. The outer diameter of the movement can be reduced because the wheel is not slid in the axial direction of the winding stem, and since the wheel does not need to be provided with a hook portion such as a latch, the length of the wheel is shortened. This has the effect. However, since the conventional switching structure of the timepiece includes the slide wheel moving member, there is a problem that the configuration is still complicated. In addition, there is also a problem that the load on the hand wheel train is correspondingly large since the small wheel wheel meshes with the hand wheel train even during normal hand operation.

[Problems to be solved by the invention]
A problem to be solved by the present invention is to provide a timepiece having a winding stem, a pinwheel and a small iron wheel, and a timepiece having a simple switching structure not using a pinwheel moving member as well as a bolt. is there.
[0008]
[Means to solve the problem]
A timepiece for solving the above-mentioned problem is provided with a winding stem mounted on the main plate so as to be positioned at at least two axial positions of a normal hand movement position and a time correction time position, and an inner periphery meshing with a corner of the winding stem. A ratchet wheel having a square hole formed therein, and a small iron that is held at an upper position when the winding stem is positioned at the normal hand operation position and is moved to a lower position when the winding stem is positioned at the time correction position. It consisted with a car. And when the small iron wheel is in the upper position, the engagement between the wheel and the wheel set wheel is disengaged, and when in the lower position, the wheel and the wheel set wheel are disengaged. They were attached to the main plate so as to mesh with each other.
[0009]
In the above-mentioned timepiece, the small iron wheel has a rotating shaft, and the small iron wheel has an upper rotating shaft guided by a guide hole formed in a train wheel bridge and a lower rotating shaft formed in a main plate. The small iron wheel is supported by the guide hole so as to be able to move up and down, and an elastic force is applied downward by a spring.
[0010]
In the above-mentioned timepiece, the small wheel has a clutch pin formed with a guide hole protruding downward at an outer peripheral portion at the center, and the small wheel has the guide hole formed on a rotating shaft fixed to a main plate. The clutch pin is penetrated and supported vertically movably by passing the clutch pin through a guide hole formed in the main plate. Further, the small iron wheel is characterized in that an elastic force is applied downward by a spring.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
The timepiece according to the first embodiment of the present invention has at least two axes of a normal hand operation position and a time adjustment position, as shown in FIG. 1 which is a cross-sectional view at the time of normal hand operation and FIG. The winding stem 1 attached to the base plate 2 so as to be positioned in the directional position, a continuous wheel 4 having an inner peripheral square hole formed to mesh with the corner 1c of the winding stem 1, and the normal operation of the winding stem 1 This is a timepiece having a vertically movable small iron wheel 5 that is held at the upper position when positioned at the hour position and is moved to the lower position when the winding stem 1 is positioned at the time correction position.
[0012]
The small movable wheel 5 that can move up and down is disengaged from the ratchet wheel 4 and the minute wheel 6 when it is at the above-mentioned position, and it is disengaged when it is at the above-mentioned lower position. 4 and the minute wheel 6 are attached to the main plate 2 so as to mesh with each other.
[0013]
That is, the small movable wheel 5 shown in FIGS. 1 and 2 that can move up and down has teeth 5a that mesh with the ratchet wheel 4 and a rotating shaft composed of the upper rotating shaft 5b and the lower rotating shaft 5c. The upper rotary shaft 5b of the small iron wheel 5 is guided by a guide hole 11a formed in the train wheel bridge 11, and the lower rotary shaft 11c is guided by a guide hole 2a formed in the main plate 2 so as to be vertically movable. ing.

This leaf spring can be formed using a spring component such as a positive terminal of a battery. However, the member for applying the downward elastic force to the small wheel is not limited to the small wheel presser spring 16 of the leaf spring shown in FIGS. 1 and 2. For example, a leaf spring or a coil spring disposed between the upper surface of the small wheel & pinion 5 and the lower surface of the opposed train wheel bridge 11 can also be used as the small wheel holding spring 16.
[0015]
In the timepiece according to the first embodiment described above, when the winding stem 1 is at the normal hand-operated position where the winding stem 1 is pushed in, as shown in FIG. And the small iron wheel 5 is pushed up to the upper position. Then, the small iron wheel 5 is disengaged from the ratchet wheel 4, and the timepiece is in the normal hand operation state. In this case, since the small wheel wheel 5 is also disengaged from the minute wheel 6, the load on the wheel train is reduced by that much.
[0016]
When the winding stem 1 is at the time-corrected position where it has been pulled out one step, the tip of the winding stem 1 is completely separated from the lower rotating shaft 5c of the small wheel 5 as shown in FIG. It is pushed down to the lower position by the elasticity of the spring. Then, the small wheel train 5 meshes with the shunting wheel 4 and the minute wheel 6, and in the order of the mushroom 1, the small wheel 4, the small wheel 5 from the small wheel 5, and the small wheel 5 from the small wheel 5. , A state in which rotational force can be transmitted from the winding stem 1 to the handwheel train, that is, a time correction state.
[0017]
Next, as shown in FIG. 3 which is a cross-sectional view at the time of normal hand operation and FIG. 4 which is a cross-sectional view at the time of time correction, the timepiece according to the second embodiment of the present invention has at least a normal hand operation position and a time correction position.

[0018]
The small movable wheel 5 that can be moved up and down is disengaged from each other when the wheel is in the upper position and the wheel train and the wheel setting wheel train. It is attached to the main plate 2 so as to mesh with the reverse wheel 6.
[0019]
That is, the small movable wheel 5 shown in FIGS. 3 and 4 that can move up and down has teeth 5a that mesh with the ratchet wheel 4 and guide holes 5d formed in the center. Further, the clutch pin 17 is located between the small iron wheel 5 and the main plate 2 and has a shape that protrudes downward from an annular portion of at least 3/4. The small iron wheel 5 allows the fixed rotating shaft 2b fixed to the main plate 2 to pass through the guide hole 5d. The clutch pin 17 is vertically movably supported by penetrating a guide hole 2c formed in the main plate 2. Further, the small iron wheel 5 is applied with an elastic force downward by a small iron wheel pressing spring 16.
[0020]
3 and 4 is a leaf spring that presses the upper surface of the small wheel 5 from above, but may be a coil spring.
[0021]
In the switching structure of the timepiece according to the second embodiment described above, when the winding stem 1 is in the normal hand-operated position where the winding stem 1 is pushed in, as shown in FIG. The clutch pin 17 and the small wheel 5 are pushed up to the upper position. Then, the small iron wheel 5 is disengaged from the ratchet wheel 4, and the timepiece is in the normal hand operation state. In this case, since the small wheel wheel 5 is also disengaged from the minute wheel 6, the load on the wheel train is reduced by that much.
[0022]
