本考案は針合せなどの操作に用いる時計などの操作装置
に関するものである。[Detailed Description of the Invention] The present invention relates to an operating device for a watch or the like used for operations such as setting hands.
従来における時計の操作装置、特に目安修正装置におい
てはラチェツト歯とラチェットバネの噛合によって修正
軸の逆転を防止していた。In conventional watch operating devices, particularly in scale adjustment devices, the adjustment shaft is prevented from reversing by meshing ratchet teeth with a ratchet spring.
この装置においては部品点数が多く設計スペースを広く
とることや、ラチェットバネ圧の設定が必要なことなど
多くの問題を生じていた。This device has many problems, including the large number of parts, requiring a large design space, and the need to set the ratchet spring pressure.
さらに、改良された操作装置においては第1図に示すよ
うに、裏ケース2に軸支された目安操作ツマミ4と噛合
する伝え車6に、コイルバネ8がかるく接触する程度に
挿入され、コイルバネ8から延び出した腕8aが地板1
0に穿設された透孔10 aに係止されていた。Furthermore, in the improved operating device, as shown in FIG. The arm 8a extending from the main plate 1
It was locked in a through hole 10a drilled in the hole 10a.
この装置で、操作ツマミ4が正回転した時には伝え車6
に挿入されたコイルバネ8が回転による曲げモーメント
によってコイルバネ8の孔径を大きくするように働くた
め、コイルバネ8は伝え車6には影響を与えず回転は通
常に行なわれる。With this device, when the operating knob 4 rotates forward, the transmission wheel 6
Since the coil spring 8 inserted into the transmission wheel 8 acts to enlarge the hole diameter of the coil spring 8 by the bending moment caused by rotation, the coil spring 8 does not affect the transmission wheel 6 and the rotation is performed normally.
操作ツマミ4が逆回転のときには、コイルバネ8が回転
による曲け゛モーメントによりコイルバネ8の孔径を小
さくするように働くため、コイルバネ8か沖間車6を弾
圧保持し、その摩擦力により逆転を防止することができ
るように構成されていた。When the operating knob 4 rotates in the reverse direction, the coil spring 8 acts to reduce the hole diameter of the coil spring 8 due to the bending moment caused by rotation, so the coil spring 8 or the floating wheel 6 is held elastically, and the frictional force thereof prevents reverse rotation. It was configured so that it could be done.
しかじなか゛らこの改良された装置においては、逆転時
に大きな力を加えることによるコイルバネの変形、ある
いは係止部からのはずれということを除去することはで
きず、大きな問題となっていた。However, with this improved device, it was not possible to eliminate the deformation of the coil spring due to the application of a large force at the time of reversal, or the possibility of the coil spring coming off the locking portion, which was a major problem.

また、目安操作ツマミ42を軸支する裏ケース44には
、目安操作ツマミ42のツマミ逆転防止爪50と係合す
る逆転防止爪52か゛設けられている。Further, the back case 44 that pivotally supports the guide operation knob 42 is provided with a reversal prevention pawl 52 that engages with a knob reversal prevention pawl 50 of the guide operation knob 42.
第5図には裏ケースに形成された逆転防止爪部の平面図
が示され、第6図には第5図のB−B線断面図か示され
ている。FIG. 5 shows a plan view of the anti-reverse claw portion formed on the back case, and FIG. 6 shows a sectional view taken along the line B--B in FIG. 5.
このように、逆転防止爪52はツマミ逆転防止爪50と
同様に、円状に形成され山部52aと谷部52 bとか
らなり、山部52 aと谷部52 bとの間は緩斜面5
2 Cまたは、崖部52 dによって連続している。In this way, like the knob reversal prevention pawl 50, the reversal prevention pawl 52 is formed in a circular shape and consists of a crest 52a and a trough 52b, and there is a gentle slope between the crest 52a and the trough 52b. 5
2 C or is continuous by a cliff portion 52 d.
本考案の第1実施例は以上の構成からなり、以下に作用
の説明をする。The first embodiment of the present invention has the above configuration, and its operation will be explained below.
第7図には目安操作ツマミ42のツマミ逆転防止爪50
と、裏ケース44に形成された逆転防止爪52とが噛み
合っている状態の断面図が示されている。Fig. 7 shows the knob 50 for preventing reverse rotation of the rough operating knob 42.
A cross-sectional view is shown in which the reverse rotation prevention pawl 52 formed on the back case 44 is engaged with the reverse rotation prevention pawl 52 .
目安操作ツマミ42に指の押圧に伴った回転力か゛加え
られると押圧方向によってはスナップフイツ1〜爪と部
材との間に間隙をもつことから目安操作ツマミが傾き、
それとともに回転方向が矢印り方向の場合には、ツマミ
逆転防止爪50の緩斜面50 Cが逆転防止爪52の緩
斜面52 Cを上昇し、目安操作ツマミ42は軸方向に
移動し、目安操作ツマミ42の回転が可能となる。When a rotational force is applied to the guide knob 42 due to finger pressure, the guide knob tilts depending on the direction of the push because there is a gap between the snap fitting 1~claw and the member.
At the same time, when the rotation direction is in the direction indicated by the arrow, the gentle slope 50C of the reverse rotation prevention claw 50 moves up the gentle slope 52C of the reverse rotation prevention claw 52, and the guideline operation knob 42 moves in the axial direction, allowing the guideline operation to be performed. Rotation of the knob 42 becomes possible.
そして、その回転は伝え車40に伝達され以下時計輪列
に伝わることになる。The rotation is then transmitted to the transmission wheel 40 and then to the clock train.
また、目安操作ツマミ42を矢印り方向とは逆の方向に
回転させようとした場合には、ツマミ逆転防止爪50の
屋内50 dが、逆転防止爪52の屋内52 dを押す
ことになるため目安操作ツマミ42は回転することばで
゛きない。Also, if you try to rotate the guide control knob 42 in the direction opposite to the direction indicated by the arrow, the indoor 50 d of the knob reversal prevention claw 50 will push the indoor 52 d of the reverse rotation prevention claw 52. The reference operation knob 42 cannot be rotated in words.
このように、本考案においては逆転防止爪を裏ケースと
操作ツマミに設けるため、従来に較べて大きな力が加わ
っても逆転を確実に防止することか゛できる。As described above, in the present invention, since the reversal prevention pawl is provided on the back case and the operation knob, reversal can be reliably prevented even if a larger force is applied than in the past.
第8図には本考案の第2実施例が示されている。FIG. 8 shows a second embodiment of the invention.
第1実施例においては目安操作ツマミ42のツマミ逆転
防止爪50と係合する逆転防止爪を裏ケース44に設け
たが、この第2実施例においては逆転防止爪(第8図の
60)を上板22に設けたことを特徴どし、逆転防止爪
60の形状およびその動作は第1実施例と同様であり、
説明を省略する。In the first embodiment, a reversal prevention pawl that engages with the knob reversal prevention pawl 50 of the standard operation knob 42 was provided on the back case 44, but in this second embodiment, a reversal prevention pawl (60 in FIG. 8) is provided. This embodiment is characterized by being provided on the upper plate 22, and the shape and operation of the anti-reverse claw 60 are the same as in the first embodiment.
The explanation will be omitted.
なお、他の構成については第1実施例と同じであり同符
−号を付して説明を省略する。Note that the other configurations are the same as those in the first embodiment, so the same reference numerals are given and the explanation will be omitted.
以上のように、本実施例では目安操作装置について説明
したが、他の操作装置についても実施可能である。As described above, although the reference operating device has been described in this embodiment, the present invention can also be implemented with other operating devices.
以にのように本考案によれば、強度の逆転力に対しても
逆転防止をすることができ、構造が簡単で部品点数の少
ない時計などの操作装置を得ることができる。As described above, according to the present invention, it is possible to prevent reverse rotation even in the case of a strong reverse force, and it is possible to obtain an operating device such as a watch that has a simple structure and a small number of parts.
また、部品点数を減少させることから設計スペースを大
幅に節減でき、時計ムーブメン1〜の薄型化および小型
化が可能となる。Further, since the number of parts is reduced, the design space can be significantly saved, and the watch movement 1 can be made thinner and smaller.
