上記遠隔操作式排水栓装置において、操作部に故障などの問題が生じた場合に、操作部から操作ボタンを取り外して修理を行う場合がある。特許文献１に記載の発明では、操作部の側面から動作部を分解して電動用駆動部を取り外せる構造としている。
しかしながら、この作業を行うためには、浴槽であればエプロン、洗面ボウルではスイッチ近傍のパネルなど、槽体の側面を開放して操作部の全体を露出させ、更にネジなどを解除して操作部の分解作業を行う必要があるなど、大変な手間がかかるものであった。また、操作体自体には特に何ら対応を行うものではなく、操作体に故障の原因があった場合には何ら解決ができないものであった。
簡単な修理方法としては、まず操作ボタンを取り外し、操作部内部に対して視認及び作業ができるようにする方法があるが、特許文献１に記載の発明にこのような方法を用いると、操作ボタンと操作体の嵌合を外す際に、操作ボタンと操作体がうまく外れず、レリースワイヤ又はロック機構の操作体と操作体の弾性嵌合を外して無理な操作体の引き上げを行ってしまい、結果電動用駆動部に係る部分を破損としてしまう場合があった。
本発明は上記問題点に鑑み発明されたものであって、遠隔操作式排水栓装置において、操作ボタンを取り外す際に操作部の破損などが生じることなく、その後の修復作業などを容易に行うことができる遠隔操作式排水栓装置を提供するものである。 In the remote-controlled drain plug device, when a problem such as a failure occurs in the operation unit, the operation button may be removed from the operation unit for repair. In the invention described in Patent Document 1, the operating portion can be disassembled from the side surface of the operating portion to remove the electric drive portion.
However, in order to perform this work, the side of the tank body, such as the apron for the bathtub and the panel near the switch for the wash bowl, is opened to expose the entire operation unit, and the screws are released to expose the operation unit. It took a lot of time and effort, such as the need to disassemble the. In addition, no particular measures are taken for the operating body itself, and if there is a cause of failure in the operating body, no solution can be made.
As a simple repair method, there is a method of first removing the operation button so that the inside of the operation unit can be visually recognized and operated. However, when such a method is used for the invention described in Patent Document 1, the operation button is used. When removing the mating of the operating body, the operating button and the operating body did not come off well, and the elastic fitting of the operating body and the operating body of the release wire or the lock mechanism was removed and the operating body was pulled up unreasonably. As a result, the part related to the electric drive unit may be damaged.
The present invention has been invented in view of the above problems, and in a remote-controlled drain plug device, subsequent repair work and the like can be easily performed without causing damage to the operation unit when the operation button is removed. It provides a remote-controlled drain plug device capable of performing.

以下に、本発明の第一実施例について、図面を参照しつつ説明する。尚、以下の各実施例への説明においては、レリースワイヤ１１のインナーワイヤ１１ｂが排水口８ａ側に移動することを「前進」、操作部Ｓ側に移動することを「後退」として記載する。また、本実施例の説明における「上」「下」は、図１の図示に基づいて記載する。
図１乃至図９に示した、本発明の第一実施例の排水栓装置は、槽体の一種である浴槽Ｂの排水配管に採用される排水栓装置であって、以下に記載する、排水口本体８、支持部材９、継手部材１０、操作部Ｓ、弁部材７、操作伝達部材としてのレリースワイヤ１１、支持部材９、ロック機構５、ガイド管１２、等の部材より構成される。
浴槽Ｂは上方が開口した箱体であって、その底面に排水口本体８を取り付けるための取付孔Ｂ１を、また上縁周縁に操作部Ｓを取り付けるための操作部取付孔Ｂ２を備えてなる。
排水口本体８は略円筒形状を成す部材であって、その上端部分外周側には、側面方向に突出するフランジ部８ｂを設けてなり、外側面には雄ネジを設けてなる。
支持部材９は、レリースワイヤ１１端部を排水口８ａ内に配置固定する部材であって、その中央部分にアウターチューブ１１ａ端部が接続される。
継手部材１０は、有底略円筒形状を成す部材であって、上方の開口に排水口本体８の雄ネジと螺合する雌ネジを、側面に内部の排水を排出するための排出口１０ａと、レリースワイヤ１１を挿通するための筒状の挿通部１０ｂを、それぞれ備えてなる。
操作部Ｓは浴槽Ｂの操作部取付孔Ｂ２に取り付けられる部材であって、以下に記載する、第一ケーシング１、第二ケーシング２、操作部本体Ｓ１、電動駆動機構６ａ、基板部材、第一操作体３、第二操作体４、操作ボタン１３、接続部材Ｃ３、第一カバー部材Ｋ１、第二カバー部材Ｋ２、から構成される。
第一ケーシング１は、略円筒形状を成す部材であって、その両端に開口を備えてなり、上端側は浴槽Ｂの操作部取付孔Ｂ２に取り付けられる。この上端側の端部は、操作ボタン１３が進退する開口部１ａを形成する。
また、開口部１ａとは反対側の端部には接続部Ｃ１を備えてなる。
第二ケーシング２は、略円筒形状を成す部材であって、両端に開口を備えてなり、上端は第一ケーシング１の接続部Ｃ１と接続される被接続部Ｃ２を備えてなる。また、その内部は、ロック機構５を弾性嵌合により着脱自在に固定できるように構成されてなる。ここで、ロック機構５と第二ケーシング２との嵌合は、後述する操作ボタン１３と第一操作体３、第一操作体３と第二操作体４、第二操作体４と保持軸５ｂ、のいずれの嵌合よりも充分に強く、操作体を介しての作業では、ロック機構５と第二ケーシング２との嵌合は解除できない。
操作部本体Ｓ１は、対向する２つの側面が開口した、略箱状の外形を備えたケーシング体であって、その上面に第二ケーシング２と同じ被接続部Ｃ２を、また該被接続部Ｃ２の同軸上であって、対向する下面に第一ケーシング１と同じ接続部Ｃ１を、それぞれ備えてなる。また、操作部本体Ｓ１内には、図４に示したように、側面に設けられた２つの開口の略中間部分に、操作部本体Ｓを二つに区画する隔壁部Ｓ２を備えてなり、操作部本体Ｓ１内部であって、隔壁部Ｓ２で区画される２つの空間の内、被接続部Ｃ２および接続部Ｃ１に連通する側の空間と、施工時に操作部本体Ｓ１に接続される第一ケーシング１、及び第二ケーシング２によって、手動操作部Ｍが形成される。
また、操作部本体Ｓ１の隔壁部Ｓ２で区画される２つの空間の内、被接続部Ｃ２および接続部Ｃ１に連通しない側の空間には、モーター等の電動用の駆動機構からなる電動駆動機構６ａと、このモーターの動作を制御する電子基板である基板部材が配置されて、遠隔操作式排水栓装置を電気的に動作させる電動駆動部６となる。
即ち、本実施例の「電動駆動部６」とは、モーターなど電動的な動作を行う電動駆動機構６ａと、それを制御する基板部材が配置される空間であると共に、この部分に収納された部材によって、電動的に遠隔操作式排水栓装置を作動させる機能を有する部分を指し示すものである。
尚、該基板部材は、給湯器の操作パネルなど、電動操作用の操作部に接続され、電力の供給を受けるとともに、電動操作用の操作部からの信号を受けて電動駆動機構６ａを動作させる。また、該電動駆動機構６ａは、後述する操作体の位置を検出することで、操作体から連動する排水口８ａの開閉状況を把握するセンサ（図示せず）を備えてなる。
モーターには、モーターが作動することにより回転する歯車部材６ｂが備えられてなり、この歯車部材６ｂが隔壁部Ｓ２の貫通孔Ｓ４を介して、電動駆動部６から手動操作部Ｍ側に突出する。尚、歯車部材６ｂにはその周囲にＯリングが取り付けられて貫通孔Ｓ４周縁に水密的に当接してなり、手動操作部Ｍ側から貫通孔Ｓ４を介して電動駆動部６側に湯水が流入しないように、水密な状態を維持することができる。
また、操作部本体Ｓ１の内部には、被接続部Ｃ２および接続部Ｃ１の中心軸と同軸となるようにして、後述する第二操作体４を配置・接続してなる。
更に、隔壁部Ｓ２の手動操作部Ｍ側に、隔壁部Ｓ２から垂直な方向に立ち上がる環状の壁面からなる、環状壁部Ｓ３を備えてなる。この環状壁部Ｓ３は、操作部本体Ｓ１の上方の開口を閉塞する際に、第一カバー部材Ｋ１によってその上端を水密的に閉塞される。また、環状壁部Ｓ３には、接続部Ｃ１側に向けて、施工時に接続部Ｃ１から操作体（ここでは第二操作体４）が余裕を持って挿通できるように、操作体よりも大きな正円の開口を備えてなる。一方、被接続部Ｃ２側は、第二操作体４の軸部分が水密的に進退できるように、壁面に軸部分の外径とほぼ同じ内径であって、Ｏリングを備えた開口のみを形成してなる。このため、第二操作体４は、第二ケーシング２が接続されている接続部Ｃ１側には引き出して操作部本体Ｓ１から抜き出すことができるが、第一ケーシング１が接続されている被接続部Ｃ２側には引き出して操作部本体Ｓ１から抜き出すことができない。
尚、施工完了時、後述するロック機構５によって、この環状壁部Ｓ３の正円の開口は閉塞される。
第一操作体３は、略円筒形状をなす部材であって、上端は後述する操作ボタン１３の下面と弾性嵌合可能に、また筒状部分の内側端部は後述する第二操作体４の上端部分と弾性嵌合可能に、それぞれ構成されてなる。また、第一操作体３の側面にはリブ片３ａが設けられてなり、開口部１ａからこのリブ片３ａを取っ手のように利用して、第一操作体３を回転させることができる。
第二操作体４は、棒状の部材であって、一端は上記第一操作体３の筒部分の端部と弾性嵌合可能に、また他端は後述するロック機構５の保持軸５ｂ端部と弾性嵌合可能に、それぞれ構成されてなる。また、第二操作体４の側面には段部４ａが設けられてなる。
また、第一操作体３の円筒形状部分の内部と、第二操作体４の棒状部分側面には合致する凹凸が設けられてなり、第一操作体３を円筒形状の中心軸を中心に回転させると、それに伴って第二操作体４も回転する。
また、図７等に示したピニオン部材１４は、筒体を、その中心軸を通過する平面にて等分したような形状を成す部材であって、その側面には歯車部材６ｂと歯合する歯合部１４ａが備えられてなり、またその内部には第二操作体４の段部４ａに対し一方向だけ係合する係止段部１４ｂが備えられてなる。
また、第二操作体４の段部４ａとピニオン部材１４の係止段部１４ｂとの係合は、第二操作体４がピニオン部材１４に対して適正な方向を向いている場合にのみ行われ、第二操作体４の軸部分を中心として定まった方向に回転させると、第二操作体４の段部４ａとピニオン部材１４の係止段部１４ｂとの係合状態を解除することができる。但し、第二操作体４の軸部分を中心とした回転動作は規制されており、通常の遠隔操作式排水栓装置の使用では、回転が生じて第二操作体４とピニオン部材１４との係合が解除されることは無い。第二操作体４を回転させてピニオン部材１４との係合を解除させるためには、使用者が第二操作体４に回転操作を行う等の、意図的に回転を行う必要がある。
尚、ピニオン部材１４は、施工完了時、操作体の一部となる第二操作体４に沿ってのみ移動可能なように、環状壁部Ｓ３内に配置される。
ここで、第二操作体４とモーターに接続された歯車部材６ｂとの連結について以下に詳述する。
第二操作体４には段部４ａがあり、この段部４ａを覆うようにしてピニオン部材１４を配置する。この時、図３に示したように、第二操作体４の段部４ａを、ピニオン部材１４の係止段部１４ｂが覆うように配置する。
また、このように配置することによって、図５に示したように、ピニオン部材１４の歯合部１４ａが歯車部材６ｂと歯合するように配置される。
このように、ピニオン部材１４を介して、第二操作体４とモーターに接続された歯車部材６ｂとは連結される。
操作ボタン１３は、遠隔操作式排水栓装置を手動にて操作する場合の使用者が、押し込み操作を行う略円盤状の部材であって、その裏側中央は、第一操作体３の上端と弾性嵌合可能に構成されてなる。
接続部材Ｃ３は、略Ｃ字形状を成す部材であって、第一ケーシング１と電動駆動部６、及び電動駆動部６と第二ケーシング２の接続部Ｃ１と被接続部Ｃ２が接続された状態において、側面方向から差し込むことで、接続状態を維持固定するように機能する。尚、特に詳述しないが、この接続部Ｃ１と被接続部Ｃ２の接続はＯリング等を介して水密的に、且つ回動可能に接続される。
また、接続部材Ｃ３を接続部Ｃ１および被接続部Ｃ２の側面方向から抜脱することで、接続部Ｃ１と被接続部Ｃ２の接続を解除することが可能である。
弁部材７は、排水口８ａの上端を閉口する略円盤状の部材であって、その下面中央部分に、弁軸１１ｃ先端との嵌合部分を構成されてなる。
レリースワイヤ１１は、側面方向に可撓性を、軸方向に剛性を有したアウターチューブ１１ａと、該アウターチューブ１１ａ内に摺動自在に配置される、側面方向に可撓性を、軸方向に剛性を有したインナーワイヤ１１ｂと、インナーワイヤ１１ｂの一方の端部に備えられた棒状の硬質の部材である弁軸１１ｃと、レリースワイヤ１１内に備えられ、インナーワイヤ１１ｂをアウターチューブ１１ａに対して弁軸１１ｃとは反対側に付勢する戻りスプリングと、から構成されてなる。

以下に、上記第一実施例の遠隔操作式排水栓装置の使用方法を説明する。まず、手動操作による排水口８ａの開閉方法について説明する。
上記のように構成した排水栓装置を使用する場合、まず弁部材７を降下して、排水口８ａが図８のように閉口した状態とする。
この状態から操作ボタン１３に押し操作を加えると、保持軸５ｂ後端が押し込まれて、インナーワイヤ１１ｂを前進させると共に、ロック機構５が作用して、インナーワイヤ１１ｂが前進した状態にて維持固定される。この動作により、インナーワイヤ１１ｂ端部の弁軸１１ｃ側の端部が突出して、図９のように弁部材７を押し上げた状態で維持固定されるため、排水口８ａが開口する。槽体である浴槽Ｂ内に排水又は湯水が溜まっていた場合、又は流入している場合、排水口８ａから排水口本体８、また継手部材１０内を通過して、排出口１０ａから下水側に排出される。
この状態から操作ボタン１３に再度押し操作を加えると、再び保持軸５ｂ後端が押し込まれて、ロック機構５の保持軸５ｂの固定状態が解除される。これによって、インナーワイヤ１１ｂは、弁部材７の自重と、レリースワイヤ１１の戻りスプリングの作用によって、保持軸５ｂと共に操作部Ｓ側に後退し、図８のように弁部材７が排水口８ａを閉口する。
以降、操作ボタン１３に押し込み操作を繰り返すことで、排水口８ａを排水口８ａから離間した操作部Ｓへの操作によって開閉することができる。 The method of using the remote-controlled drain plug device of the first embodiment will be described below. First, a method of opening and closing the drain port 8a by manual operation will be described.
When the drain plug device configured as described above is used, the valve member 7 is first lowered so that the drain port 8a is closed as shown in FIG.
When a pushing operation is applied to the operation button 13 from this state, the rear end of the holding shaft 5b is pushed forward to advance the inner wire 11b, and the lock mechanism 5 acts to maintain and fix the inner wire 11b in the advanced state. Will be done. By this operation, the end of the inner wire 11b on the valve shaft 11c side protrudes, and the valve member 7 is maintained and fixed in a pushed-up state as shown in FIG. 9, so that the drain port 8a opens. If drainage or hot water is accumulated in the bathtub B, which is a tank body, or if it is flowing in, it passes through the drainage port main body 8 and the joint member 10 from the drainage port 8a and from the discharge port 10a to the sewage side. It is discharged.
When the operation button 13 is pushed again from this state, the rear end of the holding shaft 5b is pushed again, and the fixed state of the holding shaft 5b of the lock mechanism 5 is released. As a result, the inner wire 11b retracts to the operation portion S side together with the holding shaft 5b due to the weight of the valve member 7 and the action of the return spring of the release wire 11, and the valve member 7 retracts the drain port 8a as shown in FIG. Close the mouth.
After that, by repeating the pressing operation on the operation button 13, the drain port 8a can be opened and closed by operating the operation unit S separated from the drain port 8a.

次に、電動操作による排水口８ａの開閉方法について説明する。
上記のように構成した排水栓装置を使用する場合、まず弁部材７を降下させて、図８のように、排水口８ａが閉口した状態とする。
この状態から給湯器の操作パネルなどを介して排水口８ａへの操作を行うと、電動駆動部６のモーターが動作して歯車部材６ｂが回転し、歯車部材６ｂに歯合する歯合部１４ａを有するピニオン部材１４が、ピニオン部材１４の係止段部１４ｂが第二操作体４の段部４ａに当接する方向へ移動し、操作体を、押し操作を加えられた時と同様に動作させる。これにより、保持軸５を押し込んで、インナーワイヤ１１ｂを前進させると共に、ロック機構５が作用して、インナーワイヤ１１ｂが前進した状態にて維持固定される。この動作により、インナーワイヤ１１ｂ端部の弁軸１１ｃ側の端部が突出して、弁部材７を押し上げた状態で維持固定されるため、図９のように排水口８ａが開口する。槽体内に排水又は湯水が溜まっていた場合、又は流入している場合、排水口８ａから排水口本体８、また継手部材１０内を通過して、排出口１０ａから下水側に排出される。尚、上記動作が行われたことをセンサにより電動駆動機構６ａが検知すると、電動駆動機構６ａはモーターを逆回転させ、ピニオン部材１４を当初の位置まで後退させる。
この状態から再び給湯器の操作パネルなどを介して排水口８ａへの操作を行うと、やはり電動駆動部６のモーターが動作して歯車部材６ｂが回転し、歯車部材６ｂに歯合する歯合部１４ａを有するピニオン部材１４が、ピニオン部材１４の係止段部１４ｂが第二操作体４の段部に当接する方向へ移動し、操作体を、押し操作を加えられた時と同様に動作させる。これによって、保持軸５ｂを押し込んで、ロック機構５の保持軸５ｂの固定状態が解除されることで、インナーワイヤ１１ｂは、弁部材７の自重と、レリースワイヤ１１の戻りスプリングの作用によって、保持軸５ｂと共に操作部Ｓ側に後退し、図８のように、弁部材７が排水口８ａを閉口した状態に戻る。尚、ピニオン部材１４も前述したとおり、押し込みの動作が完了したと判断された時点で、モーターが逆回転して当初の位置まで後退するため、上記操作体の動作が妨げられることは無い。
以降、電動操作により排水口８ａへの開閉操作を繰り返すことで、排水口８ａを排水口８ａから離間した操作パネルなどの操作によって開閉することができる。 Next, a method of opening and closing the drain port 8a by electric operation will be described.
When the drain plug device configured as described above is used, the valve member 7 is first lowered so that the drain port 8a is closed as shown in FIG.
When the drain port 8a is operated from this state via the operation panel of the water heater, the motor of the electric drive unit 6 operates to rotate the gear member 6b, and the tooth portion 14a meshes with the gear member 6b. The pinion member 14 having the above moves in the direction in which the locking step portion 14b of the pinion member 14 abuts on the step portion 4a of the second operating body 4, and causes the operating body to operate in the same manner as when a pushing operation is applied. .. As a result, the holding shaft 5 is pushed in to advance the inner wire 11b, and the lock mechanism 5 acts to maintain and fix the inner wire 11b in the advanced state. By this operation, the end of the inner wire 11b on the valve shaft 11c side protrudes, and the valve member 7 is maintained and fixed in a pushed-up state, so that the drain port 8a opens as shown in FIG. When drainage or hot water is accumulated in the tank, or when it is flowing in, the drainage port 8a passes through the drainage port main body 8 and the joint member 10 and is discharged from the drainage port 10a to the sewage side. When the electric drive mechanism 6a detects that the above operation has been performed by the sensor, the electric drive mechanism 6a rotates the motor in the reverse direction and retracts the pinion member 14 to the initial position.
When the drain port 8a is operated again from this state via the operation panel of the water heater, the motor of the electric drive unit 6 also operates, the gear member 6b rotates, and the teeth mesh with the gear member 6b. The pinion member 14 having the portion 14a moves in the direction in which the locking step portion 14b of the pinion member 14 comes into contact with the step portion of the second operating body 4, and the operating body operates in the same manner as when a pushing operation is applied. Let me. As a result, the holding shaft 5b is pushed in and the fixed state of the holding shaft 5b of the lock mechanism 5 is released, so that the inner wire 11b is held by the weight of the valve member 7 and the action of the return spring of the release wire 11. It retracts to the operation unit S side together with the shaft 5b, and returns to the state in which the valve member 7 closes the drain port 8a as shown in FIG. As described above, when it is determined that the pushing operation of the pinion member 14 is completed, the motor rotates in the reverse direction and retracts to the initial position, so that the operation of the operating body is not hindered.
After that, by repeating the opening / closing operation to the drain port 8a by the electric operation, the drain port 8a can be opened / closed by the operation of the operation panel or the like separated from the drain port 8a.

また、排水口８ａの開口状態では操作体は前進し、閉口状態では操作体が後退して、操作体の位置が移動している。センサを利用して操作体の位置の変位を検知することで、排水口８ａの開閉の状態を電動駆動機構６ａが検知することができる。この排水口８ａの開閉状態の検知の機能を利用して、給湯器の操作パネルに給湯を行う指示があり、センサが検知した排水口８ａの状態が開口状態であった場合、給湯器の操作パネルが自動的に排水口８ａの開閉操作を指示して排水口８ａを閉口するように構成することも可能である。 Further, in the open state of the drain port 8a, the operating body moves forward, and in the closed state, the operating body moves backward and the position of the operating body moves. By detecting the displacement of the position of the operating body using the sensor, the electric drive mechanism 6a can detect the open / closed state of the drain port 8a. When there is an instruction to supply hot water to the operation panel of the water heater using the function of detecting the open / closed state of the drain port 8a and the state of the drain port 8a detected by the sensor is the open state, the operation of the water heater is performed. It is also possible to configure the panel to automatically instruct the opening / closing operation of the drain port 8a to close the drain port 8a.

また、上記のように構成したため、排水口８ａの開閉操作において、開口、閉口の手順を、手動操作のみ、電動操作のみ、電動と手動の混在のどのような手順に沿っても行うことができる。即ち、手動操作で排水口８ａを開口した場合は手動操作で閉口しなければならない、電動操作で排水口８ａを開口した場合は電動操作で閉口しなければならない、といった制限なく自在に排水口８ａの開閉操作を行うことができる。 Further, since it is configured as described above, in the opening / closing operation of the drainage port 8a, the opening / closing procedure can be performed according to any procedure of manual operation only, electric operation only, and a mixture of electric and manual operations. .. That is, if the drainage port 8a is opened manually, the drainage port 8a must be closed manually, and if the drainage port 8a is opened by electric operation, the drainage port 8a must be closed by electric operation. Can be opened and closed.

上記のように構成した遠隔操作式排水栓装置において、故障等により、操作部Ｓ内部を確認したり、操作部Ｓ内部に作業を行う場合、まず操作ボタン１３を操作部Ｓから取り外す。この時は、操作ボタン１３と開口部１ａの隙間に冶具を差し込んで操作ボタン１３を引き出す、または操作ボタン１３上面に吸盤などを貼り付け、吸盤を取っ手代わりとして引き上げる等によって、操作ボタン１３と第一操作体３との弾性嵌合を解除し、操作部Ｓから操作ボタン１３を取り出すことができる。尚、前述の通り、第一操作体３と操作ボタン１３との弾性嵌合の嵌合強度は、第一操作体３と第二操作体４の弾性嵌合や、第二操作体４と保持軸５ｂの弾性嵌合の強度よりも弱いため、上記作業の際に、第一操作体３と操作ボタン１３以外の弾性嵌合の箇所が解除されることは無い。
この時点で、例えば第一操作体３に毛髪が絡んで動作不良を生じていた等の理由で遠隔操作式排水栓装置が操作できなくなっていた場合は、故障の原因を取り除くことで修理を行うことができる。 In the remote-controlled drain plug device configured as described above, when checking the inside of the operation unit S or performing work inside the operation unit S due to a failure or the like, the operation button 13 is first removed from the operation unit S. At this time, the operation button 13 and the operation button 13 are pulled out by inserting a jig into the gap between the operation button 13 and the opening 1a, or by attaching a suction cup or the like to the upper surface of the operation button 13 and pulling up the suction cup as a handle. The elastic fitting with the operation body 3 can be released, and the operation button 13 can be taken out from the operation unit S. As described above, the fitting strength of the elastic fitting between the first operating body 3 and the operating button 13 is the elastic fitting between the first operating body 3 and the second operating body 4 and the holding strength with the second operating body 4. Since it is weaker than the elastic fitting strength of the shaft 5b, the elastic fitting points other than the first operating body 3 and the operating button 13 are not released during the above operation.
At this point, if the remote-controlled drain plug device cannot be operated due to, for example, hair being entangled with the first operating body 3 and causing a malfunction, repair is performed by removing the cause of the failure. be able to.

上記の方法にて故障を解決できなかった場合、操作体３のリブ片３ａを取っ手代わりに利用して第一操作体３を円筒部分の中心軸を中心として回転させる。第一操作体３の円筒形状部分の内部と、第二操作体４の棒状部分側面には合致する凹凸が設けられているため、第一操作体３を回転させると、それに伴って第二操作体４も回転し、この意図的な回転によって、第二操作体４の段部４ａとピニオン部材１４の係止段部１４ｂとの係合状態が解除される。 If the failure cannot be solved by the above method, the rib piece 3a of the operating body 3 is used instead of the handle to rotate the first operating body 3 about the central axis of the cylindrical portion. Since the inside of the cylindrical portion of the first operating body 3 and the side surface of the rod-shaped portion of the second operating body 4 are provided with matching irregularities, when the first operating body 3 is rotated, the second operation is performed accordingly. The body 4 also rotates, and by this intentional rotation, the engagement state between the step portion 4a of the second operating body 4 and the locking step portion 14b of the pinion member 14 is released.

上記の対応を行った上で、修理の手順は故障の状況によって変化する。
第一操作体３を操作部Ｓから取り出したい場合は、そのまま第一操作体３を開口部１ａから引き上げて操作部Ｓから取り外す。この場合、弾性嵌合の強度の差異によって、まず第二操作体４とロック機構５の保持軸５ｂの弾性嵌合が解除される。尚、解除作業を行うのに必要な距離を確保するため、ロック機構５の保持軸５ｃを下方側に前進した状態で固定させておく必要がある場合がある。次に第一操作体３と第二操作体４の弾性嵌合を解除することで、第一操作体３が開口部１ａから取り出される。第二操作体４は、上方の被接続部Ｃ２を介して操作部本体Ｓ２から抜脱することは不可能なため、第一操作体３を引き上げると、第一操作体３と第二操作体４の弾性嵌合を解除することができる。この時、第二操作体４とピニオン部材１４との係合は解除されているため、第二操作体４を通常の使用では達しないほどに上方まで引き上げても、操作部Ｓ内に破損などは生じない。 After taking the above measures, the repair procedure will change depending on the failure situation.
When it is desired to take out the first operating body 3 from the operating unit S, the first operating body 3 is pulled up from the opening 1a as it is and removed from the operating unit S. In this case, the elastic fitting of the second operating body 4 and the holding shaft 5b of the lock mechanism 5 is first released due to the difference in the strength of the elastic fitting. In addition, in order to secure the distance required for performing the release work, it may be necessary to fix the holding shaft 5c of the lock mechanism 5 in a state of being advanced downward. Next, the first operating body 3 is taken out from the opening 1a by releasing the elastic fitting between the first operating body 3 and the second operating body 4. Since the second operating body 4 cannot be detached from the operating unit main body S2 via the upper connected portion C2, when the first operating body 3 is pulled up, the first operating body 3 and the second operating body 4 are pulled up. The elastic fitting of 4 can be released. At this time, since the engagement between the second operating body 4 and the pinion member 14 is released, even if the second operating body 4 is pulled upward to the extent that it cannot be reached in normal use, the inside of the operating portion S may be damaged. Does not occur.

修理の過程において、操作部本体Ｓ１を浴槽Ｂから分離させる、つまり浴槽Ｂに取り付けられている第一ケーシング１から分離させる場合は、操作部本体Ｓ２と第一ケーシング１との接続を、接続部材Ｃ３を脱着することで解除し、操作部本体Ｓ１を第一ケーシング１から分離させることができる。この時、第一操作体３を操作部本体Ｓ１側に接続したまま操作部本体Ｓ１を浴槽Ｂから分離させるか、事前に第一操作体３を取り出した上で操作部本体Ｓ１を浴槽Ｂから分離させるかは、段落００２０及び段落００２１の作業を行う／行わないにより作業者が自由に選択することができる。 In the process of repair, when the operation unit main body S1 is separated from the bathtub B, that is, from the first casing 1 attached to the bathtub B, the connection between the operation unit main body S2 and the first casing 1 is connected to the connecting member. It can be released by attaching and detaching C3, and the operation unit main body S1 can be separated from the first casing 1. At this time, the operation unit body S1 is separated from the bathtub B while the first operation body 3 is connected to the operation unit body S1 side, or the operation unit body S1 is removed from the bathtub B after the first operation body 3 is taken out in advance. The operator can freely select whether to separate the cells depending on whether or not the operations of paragraphs 0020 and 0021 are performed.

また、修理の過程において、第二ケーシング２を操作部本体Ｓ１から分離させる場合は、操作部本体Ｓ２と第二ケーシング２との接続を、接続部材Ｃ３を脱着することで解除し、操作部本体Ｓ２を第一ケーシング１から分離させることができる。
この時に、第二操作体４の段部４ａとピニオン部材１４の係止段部１４ａの係合を解除した上で、第一操作体３を充分に引き上げることで、第二操作体４と保持軸５ｂの弾性嵌合を解除することができる。尚、この際に第一操作体３と第二操作体４の弾性嵌合を解除する／解除しないは、適宜作業者が状況に応じて判断することである。
前述の通り、第一操作体３と第二操作体４の弾性嵌合を解除する場合必要な応力は、第二操作体４と保持軸５ｂを解除する場合に必要な応力よりも大きいため、第一操作体３を引き上げることで、第一操作体３と第二操作体４の嵌合が解除されることなく、第二操作体４と保持軸５ｂの弾性嵌合を解除することができる。このように、操作部本体Ｓ２から第二ケーシング２を分離させる際に、事前に開口部１ａからの操作によって操作体と保持軸５ｂとの弾性嵌合を解除しておくことで、第二ケーシング２の分離作業を容易に行うことができる。
上記のようにして、操作ボタン１３を取り外した後、開口部１ａからの作業によって、修理作業の際の操作体の接続状況を調整することができる。 Further, in the process of repair, when the second casing 2 is separated from the operation unit main body S1, the connection between the operation unit main body S2 and the second casing 2 is released by detaching the connecting member C3, and the operation unit main body is released. S2 can be separated from the first casing 1.
At this time, after disengaging the step portion 4a of the second operating body 4 and the locking step portion 14a of the pinion member 14, the first operating body 3 is sufficiently pulled up to hold the pinion member 14 with the second operating body 4. The elastic fitting of the shaft 5b can be released. At this time, it is up to the operator to appropriately determine whether to release / not release the elastic fitting of the first operating body 3 and the second operating body 4.
As described above, the stress required to release the elastic fitting between the first operating body 3 and the second operating body 4 is larger than the stress required to release the second operating body 4 and the holding shaft 5b. By pulling up the first operating body 3, the elastic fitting between the second operating body 4 and the holding shaft 5b can be released without releasing the fitting between the first operating body 3 and the second operating body 4. .. In this way, when the second casing 2 is separated from the operation unit main body S2, the elastic fitting between the operating body and the holding shaft 5b is released in advance by the operation from the opening 1a, so that the second casing is released. The separation work of 2 can be easily performed.
After removing the operation button 13 as described above, the connection status of the operating body at the time of repair work can be adjusted by the work from the opening 1a.

本発明の実施例は以上のようであるが本発明は上記実施例に限定される物ではなく、主旨を変更しない範囲において自由に変更が可能である。
例えば、上記第一実施例は、手動・電動兼用の遠隔操作式排水栓装置であり、操作伝達部材であるレリースワイヤ１１と操作体の間には、ロック機構５が配置されてなるが、本発明は上記実施例に限定されるものではなく、図１０に示したように、手動専用の遠隔操作式排水栓装置において、操作体とレリースワイヤ端部を直接嵌合によって接続するように構成しても良い。
図１０に示した遠隔操作式排水栓装置では、操作ボタン１３は操作体上端と嵌合してなり、また操作体下端はインナーワイヤ１１のレリースワイヤ１１ｂ上端と嵌合してなる。この時、操作ボタン１３と操作体Ｏ、操作体Ｏとインナーワイヤ１１端部とは、それぞれ弾性嵌合により押し付けることにより嵌合し、引き離すことで解除できる。その弾性嵌合の強度、つまり引き離す場合にどれほどの応力を離間方向に加えれば部材同士の嵌合を解除できるか、について、図１０の実施例では、操作体Ｏとインナーワイヤ１１ｂの弾性嵌合を解除する応力の方が、操作体Ｏとボタン部材１３弾性嵌合を解除する応力よりも強い。尚、レリースワイヤ１１と第二ケーシング２との嵌合は、操作ボタン１３と操作体Ｏや、操作体Ｏとインナーワイヤ１１ｂの、いずれの嵌合よりも充分に強く、操作体Ｏを介しての作業では、レリースワイヤ１１と第二ケーシング２との嵌合は解除できない。
また、ロック機構５は図示しない排水口側の８ａ内の支持部材９内部に組み込まれてなり、操作ボタン１３に押し込み操作を行うと、その操作は操作体Ｏ、及びレリースワイヤ１１のインナーワイヤ１１ｂを介してロック機構５に伝達され、操作ボタン１３の操作の都度、弁部材７を上昇させ排水口８ａを開口した状態を維持して固定／固定を解除し弁部材７を降下させて排水口８ａを閉塞する、を繰り返すように動作させることができる。また、故障などが生じた場合は、第一実施例と同様に、まず操作ボタン１３を取り外してその内部を確認し、その上で対応を行うことができる。前述の通り、操作体Ｏとインナーワイヤ１１ｂの弾性嵌合の強度が、操作体Ｏと操作ボタン１３の弾性嵌合の強度より強いため、誤って操作体Ｏとインナーワイヤ１１ｂの弾性嵌合を解除することなく確実に操作ボタン１３の弾性嵌合のみを解除できる。
その後、必要に応じて開口部１ａより操作体Ｏを取り出したり、あるいは冶具などを用いてレリースワイヤ１１と操作部Ｓとの嵌合を解除し取り出す等の対応を行うことができる。 Examples of the present invention are as described above, but the present invention is not limited to the above examples, and can be freely changed without changing the gist.
For example, the first embodiment is a remote-controlled drain plug device for both manual and electric use, and a lock mechanism 5 is arranged between the release wire 11 which is an operation transmission member and the operating body. The present invention is not limited to the above embodiment, and as shown in FIG. 10, in a remote-controlled drain plug device dedicated to manual operation, the operating body and the end of the release wire are configured to be directly connected by fitting. You may.
In the remote-controlled drain plug device shown in FIG. 10, the operation button 13 is fitted to the upper end of the operating body, and the lower end of the operating body is fitted to the upper end of the release wire 11b of the inner wire 11. At this time, the operation button 13 and the operation body O, and the operation body O and the end of the inner wire 11 are fitted by being pressed by elastic fitting, and can be released by being pulled apart. Regarding the strength of the elastic fitting, that is, how much stress should be applied in the separating direction to release the fitting of the members in the separation direction, in the embodiment of FIG. 10, the operating body O and the inner wire 11b are elastically fitted. The stress for releasing the elastic fitting between the operating body O and the button member 13 is stronger than the stress for releasing the elastic fitting. The fitting of the release wire 11 and the second casing 2 is sufficiently stronger than the fitting of the operation button 13 and the operating body O, or the operating body O and the inner wire 11b, and is via the operating body O. In the above operation, the release wire 11 and the second casing 2 cannot be released from each other.
Further, the lock mechanism 5 is incorporated inside a support member 9 in 8a on the drain port side (not shown), and when a pushing operation is performed on the operation button 13, the operation is performed on the operating body O and the inner wire 11b of the release wire 11. It is transmitted to the lock mechanism 5 via the wire, and each time the operation button 13 is operated, the valve member 7 is raised to maintain the state in which the drain port 8a is opened, the fixing / fixing is released, and the valve member 7 is lowered to lower the drain port. It can be operated so as to repeatedly close 8a. Further, when a failure or the like occurs, as in the first embodiment, the operation button 13 can be first removed, the inside thereof can be checked, and then a countermeasure can be taken. As described above, since the strength of the elastic fitting between the operating body O and the inner wire 11b is stronger than the strength of the elastic fitting between the operating body O and the operating button 13, the elastic fitting between the operating body O and the inner wire 11b is erroneously performed. Only the elastic fitting of the operation button 13 can be surely released without releasing it.
After that, if necessary, the operating body O can be taken out from the opening 1a, or the release wire 11 and the operating portion S can be released from the mating and taken out by using a jig or the like.

また、上記実施例では、操作ボタン１３と操作体Ｏの嵌合方法、操作体Ｏと操作伝達部材であるレリースワイヤ１１のインナーワイヤ１１ｂ端部又はロック機構５の軸部である保持軸５ｂとの嵌合方法、又は操作体Ｏ同士である第一操作体３と第二操作体４との嵌合方法は、樹脂弾性等を利用した弾性嵌合に限定されているが、本発明は上記実施例に限定されるものではなく、例えばＯリング等の部材を介しての弾性嵌合や、単に表面の摩擦などを利用しての嵌合等、軸方向に応力を加えることだけで嵌合が行われ、又は解除される嵌合の方法であれば、どのような嵌合方法を採用しても構わない。 Further, in the above embodiment, the method of fitting the operation button 13 and the operation body O, the end of the inner wire 11b of the operation body O and the release wire 11 which is the operation transmission member, or the holding shaft 5b which is the shaft part of the lock mechanism 5 The fitting method of the first operating body 3 and the second operating body 4 which are the operating bodies O are limited to elastic fitting using resin elasticity or the like, but the present invention is described above. The fitting is not limited to the embodiment, and fitting is performed only by applying stress in the axial direction, for example, elastic fitting via a member such as an O-ring, or simply fitting using surface friction or the like. Any fitting method may be adopted as long as the fitting method is performed or released.

また、上記実施例では、遠隔操作式排水栓装置を浴槽Ｂの遠隔操作式排水栓装置としているが、本発明は上記実施例に限定されるものではなく、洗面台の洗面ボウルや、流し台のシンク等に組み込んで利用するようにしても構わない。 Further, in the above embodiment, the remote-controlled drain plug device is used as the remote-controlled drain plug device for the bathtub B, but the present invention is not limited to the above embodiment, and the wash basin wash bowl or sink You may use it by incorporating it in a sink or the like.
