Description
【０００１】0001
本考案は腕時計の指針修正機構に関するものである。 The present invention relates to a pointer adjustment mechanism for a wristwatch.
【０００２】0002
腕時計の成熟化に伴い時計の低コスト化が押し進められ、低コスト化を達成さ せるためにコストダウン効果の大きい指針修正機構の構造の簡素化、部品点数削 減及び裏回り部品のプラスチック化などが課題となっていた。 With the maturation of wristwatches, the cost of watches has been reduced, and lower costs have been achieved. In order to improve Issues such as reducing the number of parts and using plastic for behind-the-scenes parts were issues.
【０００３】 従来の時計の指針修正機構は分針車の分針歯車と分カナがスリップする方式が とられており、周知の如く指針修正時には巻真を引き出すことにより、巻真の角 部と係合し、巻真と一体に回転するツヅミ車から小鉄車、日ノ裏車などの指針輪 列を介して分針車及び筒車を回転させて指針修正を行っている。また、指針修正 時は分針車の分針歯車と分針カナとの摩擦嵌合によるスリップ機構により、分針 歯車、３番車、４番車への輪列系列には回転が伝達されない様になっている。0003 The pointer adjustment mechanism of conventional watches is a system in which the minute hand gear and minute pinion of the minute hand slip. As is well known, when adjusting the needle, the corner of the winding stem can be adjusted by pulling out the winding stem. The pointer wheel of Tsuzumi wheels, Kotetsu cars, Hinoura cars, etc. that engages with the winding stem and rotates together with the winding stem. Pointers are corrected by rotating the minute wheel and hour wheel through the rows. Also, the guidelines have been revised. The hour is controlled by a slip mechanism created by a friction fit between the minute hand gear and the minute hand pinion. Rotation is not transmitted to the gear train to the gears, 3rd wheel, and 4th wheel.
【０００４】 この様な分針車にスリップ機構を設けた構造に於いてはスリップトルク値が低 いと分針のアンバランスの影響により軽衝撃で分針飛びが発生し、又スリップト ルクが高いと指針修正輪列の回転負荷が大きくなり、指針修正時に針回しゴリ、 或いはツヅミ車、小鉄車、日ノ裏車などの指針修正輪列の磨耗や破損などの問題 が発生しやすく、従ってスリップトルク値の管理が難しく大きなコストアップ要 因となっていた。又ツヅミ車及び分針車、日ノ裏車などの指針修正輪列のプラス チック化に対しても歯の強度が持たないため実現性は困難であった。0004 In this structure where the minute wheel is equipped with a slip mechanism, the slip torque value is low. Due to the unbalance of the minute hand, a slight impact may cause the minute hand to jump, or the minute hand may slip. If the torque is high, the rotational load on the pointer correction wheel train will be large, causing the needle to rotate when adjusting the pointer. Or problems such as wear and tear on the guideline correction wheel train of Tsuzumi cars, Kotetsu cars, Hinoura cars, etc. Therefore, it is difficult to control the slip torque value and requires a large increase in cost. It was the cause. Also, the addition of pointer correction wheel trains such as Tsuzumi wheel, minute hand wheel, and Hinoura wheel. It was difficult to realize this method because the teeth did not have enough strength to withstand ticking.
【０００５】 この分針車のスリップ構造を廃して指針修正機構を簡素化する方式として、指 針修正時に３番カナと分針歯車の噛合いを何らかの方法で外す構造が考案されて いる。例えば実開昭６２─１６０３８７号公報の時計番車構造によれば、地板よ り一体成形されたボスを中心に回転可能に軸支された穴部と３番車ホゾの一方を 軸支する穴部と巻真先端部によって回転規制される立ち曲げ弾性部を有する作動 レバーにより、巻真を指針修正位置にセットすることにより３番車のカナと２番 車の歯車との噛合い係合を外す構造がとられている。[0005] As a method to simplify the pointer correction mechanism by eliminating the slip structure of the minute wheel, the pointer A structure was devised to remove the engagement between the No. 3 pinion and the minute hand gear in some way when adjusting the hands. There is. For example, according to the clock wheel structure disclosed in Japanese Utility Model Application No. 62-160387, the main plate One side of the hole and the tenon of the third wheel, which are rotatably supported around the integrally molded boss. Operation with a vertical bending elastic part whose rotation is regulated by the shaft-supporting hole and the tip of the winding stem. By setting the winding stem to the pointer correction position using the lever, the pinion of the 3rd wheel and the 2nd wheel are adjusted. It has a structure that allows it to be disengaged from the gears of the car.
【０００６】 このような指針修正機構に於いて、指針修正時に２番歯車と３番カナの噛合い 係合を外すことにより分針車のスリップ機構が廃止出来、且つ２番歯車と２番カ ナとの一体化も可能となる。また従来の２番車のスリップトルクによるツヅミ車 、小鉄車、日ノ裏車などの指針輪列への回転負荷がなくなり、指針修正トルクが 微少となるため指針修正輪列のプラスチック加工による加工容易化或いはプラス チック一体成形による部品点数削減が出来、コストダウンがはかれる。[0006] In such a pointer correction mechanism, when adjusting the pointer, the meshing of the No. 2 gear and the No. 3 pinion By disengaging the engagement, the slip mechanism of the minute hand wheel can be abolished, and the 2nd gear and 2nd gear can be removed. It also becomes possible to integrate with Na. Also, the Tsuzumi car due to the slip torque of the conventional second car , Kotetsu cars, Hinoura cars, etc., the rotational load on the pointer wheel train is eliminated, and the pointer correction torque is reduced. Since the amount is minute, the pointer correction wheel train can be easily processed by plastic processing or it can be improved. Integral molding reduces the number of parts and reduces costs.
【０００７】[0007]
しかしながら実開昭６２─１６０３８７号公報に於いては巻真の指針修正位置 にて巻真を回転し、分針を所定の位置に時刻合わせをし、巻真を押し戻した時に 、３番カナ側のホゾを軸支している作動レバーが巻真の動きに連動しながら回転 動作して２番車と３番車との噛合い係合が行われるが、その際２番車の歯車に対 して３番車のカナの歯の位置が一致していない場合（時刻合わせをする際に秒針 の位置に関係なく分針を所定の位置に合わせ込むことが多く、従って２番歯車と ３番カナの歯の位相関係は必ずしも一定しないためこの様な現象が起り得る）に は、３番車はローター（図示せず）までの輪列系列と噛合状態となっているため に３番車自身は回転不能のため、３番カナの歯の位置に対して２番歯車が強制的 に回転されながらい噛合係合することになる。 However, in Utility Model Application No. 62-160387, the pointer correction position of the winding stem is Rotate the winding stem with , set the minute hand to the specified position, and push the winding stem back. , the operating lever that pivots the tenon on the No. 3 pinion side rotates in conjunction with the movement of the winding stem. The second wheel and the third wheel are engaged with each other, but at that time, the gear of the second wheel is engaged with the second wheel. If the positions of the pinion teeth on the third wheel do not match (when setting the time, the second hand The minute hand is often set to the specified position regardless of the position of the second gear, and therefore the second gear and This phenomenon can occur because the phase relationship between the teeth of the third pinion is not necessarily constant.) This is because the third wheel is in mesh with the gear train up to the rotor (not shown). Since the 3rd wheel itself cannot rotate, the 2nd gear is forced to the position of the teeth of the 3rd pinion. This results in a meshing engagement while being rotated.
【０００８】 従って２番車に固着された分針が回転され、所定の位置に合わせた時刻に対し て分針位置がズレることになり、例えば２番歯車の歯数が６０枚とすると、最悪 では２番歯車の歯が１／２ピッチずれることになり、分針位置としては６０（分 ）×１／６０×１／２＝０．５分（＝３０秒）だけ、分針ズレが発生し、時刻合 わせが正確に行われない欠点があった。[0008] Therefore, the minute hand fixed to the second wheel is rotated, and the minute hand is set at a predetermined position. For example, if the number 2 gear has 60 teeth, the minute hand position will shift. In this case, the teeth of the No. 2 gear will be shifted by 1/2 pitch, and the minute hand position will be 60 (minute). ) × 1/60 × 1/2 = 0.5 minutes (= 30 seconds), the minute hand is misaligned, and the time is not set. There was a drawback that the alignment was not performed accurately.
【０００９】 本考案の目的は以上の様な欠点を除去させるために時刻合わせ後の巻真押込み 時の分針ズレを解消し、正確な時刻合わせが行える腕時計の指針修正機構を提供 するものでる。[0009] The purpose of this invention is to eliminate the above-mentioned drawbacks when the winding stem is pushed in after setting the time. Providing a wristwatch pointer correction mechanism that eliminates the misalignment of the hour and minute hands and allows accurate time setting. There is something to do.

The vertical bent portion 2c of the actuating lever 2, which was in contact with the tip 1a of the winding stem 1, is now restricted. When released, the spring portion 2b swings counterclockwise due to the spring force, and the spring tip 2d changes its shape. By releasing the side pressure of the part 3b and pushing up the shaped part 3c, the third wheel release lever is released. The bar 3 rotates around both tenons 3d and 3e, and the outer shape of the third wheel release lever 3g is Its position is regulated by coming into contact with the outer portion 11c of the train wheel bridge. Therefore, the third wheel 6 is Interlocked with the rotation of the third wheel release lever 3, which pivotally supports the tenon 6d on the third gear 6a side. Then, the main plate 10 is tilted about the axis 10d as a fulcrum, and the number 4 pinion 4b and the number 3 gear 6a are aligned. The mesh becomes disengaged.
【００１６】 この時、３番車６の歯車６ａ側のホゾ肩６ｅを受ける３番車掛け外しレバー３ のアガキ規制部３ｆは、３番車６の軸心に対して４番車４側と反対の片側のみで 受け、４番車４側は浚イ部３ｈを設けているので３番車６は傾いた状態に於いて もキシむことなく一定の縦アガキが得られるようになっている。[0016] At this time, the third wheel release lever 3 receives the tenon shoulder 6e on the gear 6a side of the third wheel 6. The backlash regulating portion 3f is only on one side opposite to the fourth wheel 4 side with respect to the axis of the third wheel 6. Since a dredging part 3h is provided on the side of the receiver and the fourth wheel 4, the third wheel 6 is in a tilted state. It is now possible to obtain a certain amount of vertical agitation without causing any strain.
【００１７】 又、時刻修正後の巻真押し戻し操作に於いて、３番歯車６ａと４番カナ４ｂが 噛合係合するときに、４番カナ４ｂの歯の位置に対して３番歯車６ａの歯の位相 がズレていた場合には４番カナ４ｂの歯数を８枚とすると最悪４番カナ４ｂの歯 の１／２ピッチだけ３番歯車６ａが強制的に噛合係合するが、分針のズレ量とし ては６〇秒×１／８×１／２＝３．７５秒であり、約１／１０と大巾減少させる ことが出来る。[0017] Also, when pushing back the winder after adjusting the time, the 3rd gear 6a and 4th pinion 4b are When meshing, the phase of the teeth of No. 3 gear 6a with respect to the position of the teeth of No. 4 pinion 4b If the number of teeth of No. 4 pinion 4b is 8, in the worst case, the teeth of No. 4 pinion 4b are misaligned. The third gear 6a is forcibly engaged by 1/2 pitch of the minute hand. is 60 seconds x 1/8 x 1/2 = 3.75 seconds, which is a huge reduction of about 1/10. I can do it.
【００１８】[0018]
以上の説明で明らかな様に本考案によれば分針車のスリップ機能の廃止が可能 である実開昭６２−１６０３８号公報記載の分針歯車と３番カナとの噛合係合を 外すのに対して、３番歯車と４番カナとの噛合係合を外す指針修正機構なので時 刻修正後の巻真の押し戻し操作において、４番カナの歯の位置に対して３番歯車 が噛合係合する際に、最悪４番カナの歯の１／２ピッチだけ３番歯車が回転され たとしても分針ズレ量は微少であるため、従来の腕時計と同様に信頼性の高い時 刻合わせを行うことが出来る。 As is clear from the above explanation, according to the present invention, it is possible to abolish the slip function of the minute wheel. The meshing engagement between the minute hand gear and the No. 3 pinion described in Japanese Utility Model Application No. 62-16038 is The pointer correction mechanism removes the meshing engagement between the No. 3 gear and the No. 4 pinion. When pushing back the winding stem after the time correction, the number 3 gear is In the worst case, the No. 3 gear is rotated by 1/2 pitch of the No. 4 pinion tooth when the gears mesh and engage. Even if the minute hand shifts, the amount of deviation is small, so it is as reliable as a conventional wristwatch. You can make adjustments.
【００１９】 又、３番車掛け外しレバーは回転軸となる両ホゾを地板と受で軸支しているの で、３番車掛け外しレバーの作動はアオリが無く、且つ安定した回転動作が得ら れる。又運針状態での３番車掛け外しレバーの平面的な位置決めを、３番車掛け 外しレバーの３番車ホゾ穴の近傍の形状部を輪列受外形部に当接させて行ってい るので３番車上ホゾの平面位置精度が確保出来、３番歯車と４番カナの噛合い精 度を保証することが出来る。[0019] Also, the third wheel release lever has both tenons, which act as rotational axes, supported by the main plate and bridge. So, the operation of the third wheel release lever has no tilting and stable rotational movement can be obtained. It will be done. In addition, the flat positioning of the third wheel release lever while the hands are moving is The part of the release lever near the third wheel mortise is in contact with the outer part of the gear train bridge. As a result, the plane position accuracy of the upper tenon of the No. 3 wheel can be ensured, and the meshing precision of the No. 3 gear and No. 4 pinion can be ensured. We can guarantee the degree of
【００２０】 又、巻真の指針修正状態での２番歯車と３番カナの平面的な噛合いの変化量が 最小限となるように、２番歯車と３番カナとの噛合い高さ位置と、３番車のカナ 側の軸受部とがほぼ同一断面高さとなっており、且つ、３番車の歯車側のホゾ肩 を受ける３番車掛け外しレバーのアガキ規制部を、３番車のホゾの中心に対して ４番車側と反対の片側のみで受けているので、３番車が傾いた状態でも縦アガキ が一定に保持されるので断面的な噛合い高さ位置も安定する。従って巻真の指針 修正位置における３番車が傾けられた状態での２番歯車と３番カナとの噛合係合 は、噛合浅による噛合突っ張りの不具合も起きることなく安定した噛合係合が得 られるので、巻真の回転操作による指針修正が正常に行える。[0020] Also, the amount of change in the planar engagement between the No. 2 gear and the No. 3 pinion when the winding stem pointer is adjusted is The meshing height position of the 2nd gear and the 3rd pinion and the pinion of the 3rd wheel should be adjusted to the minimum. The bearing part on the side has almost the same cross-sectional height, and the tenon shoulder on the gear side of the third wheel Place the release regulating part of the third wheel release lever against the center of the tenon of the third wheel. Since it is supported only on one side opposite to the 4th wheel side, even if the 3rd wheel is tilted, it will not move vertically. Since this is held constant, the cross-sectional engagement height position is also stable. Therefore, the winding stem guideline Meshing engagement between the 2nd gear and the 3rd pinion when the 3rd wheel is tilted at the corrected position This allows for stable meshing engagement without the problem of meshing tension due to shallow meshing. Therefore, the needle can be corrected normally by rotating the winding stem.
