Description

本発明は、槽体の排水口を、排水口から離間した位置に設けた操作部への操作により開閉する遠隔操作式の排水栓装置に関するものであって、特に手動操作と、電動による操作の両方を兼用する電動・手動兼用式の遠隔操作式排水栓装置の操作部に関するものである。 The present invention relates to a remote-controlled drain plug device that opens and closes the drain port of a tank body by operating an operation unit provided at a position spaced from the drain port, and particularly relates to manual operation and electric operation. The present invention relates to an operating portion of a remote operated drain plug device that can be used for both electric and manual use.

従来より、浴槽や洗面ボウルなどの槽体の内部に生じた排水を処理するため、槽体の底面等に排水口を設け、この排水口から配管部材を介し、下水側に排水を排出する方法が広く知られている。また、槽体内に水を溜める場合に、弁部材の昇降を利用して排水口を開閉する方法があるが、この弁部材による排水口の開閉を、弁部材や排水口から離間した位置、例えば槽体の縁部や槽体側面の上方に設けた操作部への操作によって行う遠隔操作式排水栓装置が知られている。
広く知られた遠隔操作式排水栓装置としては、特許文献1に記載のような、槽体の底面に設けられた排水口と、排水口を上下動することによって閉塞する弁部材と、槽体の近傍に備えられた、ボタン部材及び操作体を有する操作部と、操作部に加えられた操作を排水口に備えられた弁部材に伝達するレリースワイヤと、から構成されるものがある。
この特許文献1の遠隔操作式排水栓装置の操作部は、一端が開口した開口部を備えた箱状部分を備えてなり、その開口部の内部に操作用のボタン部材を配置して構成してなる。
また、操作部には電動操作のため、モーター等からなる電動用駆動部を併設して構成してなる。
また、特許文献1に記載された遠隔操作式排水栓装置では、弁部材の上昇状態を維持するため、排水口にロック機構(スラストロック機構)が備えられてなり、ロック機構の一端に弁部材が、他端にレリースワイヤが接続されてなる。
該操作部にて手動による排水口の開閉操作を行う場合、ボタン部材を押し込むことで、ボタン部材に接続された操作体(特許文献1では「連結軸」と記載)が進退し、排水口まで延設されたレリースワイヤ端部を押し込むことでロック機構が動作し、弁部材が昇降して排水口が開閉される。また、該操作部にて電動による排水口の開閉操作を行う場合、電動の操作にて電動用駆動部を動作させると、モーターの動作に応じて操作体が進退され、排水口まで延設されたレリースワイヤ端部を押し込むことでロック機構が動作し、弁部材が昇降して排水口が開閉される。
Conventionally, in order to treat the wastewater generated inside the tank body such as a bathtub or a washbowl, a drainage port is provided at the bottom of the tank body, etc., and the wastewater is discharged from this drain port to the sewer side through a piping member. is widely known. In addition, when water is stored in the tank body, there is a method of opening and closing the drain by utilizing the elevation of the valve member. A remotely operated drain plug device is known which is operated by operating an operation part provided on the edge of the tank body or on the upper side of the tank body.
As a widely known remote-operated drain plug device, as described in Patent Document 1, a drain port provided on the bottom surface of a tank body, a valve member that closes the drain port by moving up and down, and a tank body and a release wire for transmitting an operation applied to the operation part to a valve member provided in the drain port.
The operating portion of the remote-controlled drain plug device of Patent Document 1 comprises a box-shaped portion having an opening with one end open, and a button member for operation is arranged inside the opening. It becomes

Further, in the remote-controlled drain plug device described in Patent Document 1, a lock mechanism (thrust lock mechanism) is provided at the drain port in order to maintain the raised state of the valve member. is connected to the release wire at the other end.
When the operation unit is used to manually open and close the drain port, by pushing the button member, the operating body connected to the button member (described as a “connecting shaft” in Patent Document 1) advances and retreats to the drain port. Pushing in the end of the extended release wire activates the lock mechanism, which raises and lowers the valve member to open and close the drain port. In addition, when the operation part is used to electrically open and close the drain, when the electric driving part is operated by the electric operation, the operating body moves back and forth according to the operation of the motor, and extends to the drain. By pushing the end of the release wire, the lock mechanism operates, and the valve member moves up and down to open and close the drain port.

特開2003-247253号Japanese Patent Application Laid-Open No. 2003-247253

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 part, the operation button may be removed from the operation part for repair. In the invention described in Patent Document 1, a structure is adopted in which an electric drive section can be removed by disassembling the operation section from the side surface of the operation section.
However, in order to perform this work, it is necessary to open the side of the tub body, such as the apron for a bathtub and the panel near the switch for a washbowl, to expose the entire operation section, and then unscrew the screws to expose the operation section. It took a lot of time and effort, such as the need to disassemble the parts. In addition, no special measures were taken for the operating body itself, and if there was a cause of failure in the operating body, nothing could be done to solve the problem.
As a simple repair method, there is a method in which the operation button is first removed so that the inside of the operation unit can be visually recognized and the work can be performed. When the operating body is disengaged from the operating body, the operating button and the operating body cannot be detached well, and the elastic engagement between the operating body and the operating body of the release wire or the lock mechanism is disengaged, and the operating body is forced to be pulled up. As a result, the portion related to the electric drive unit may be damaged.
SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems. To provide a remotely operated drain plug device capable of

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。

When the drain port 8a is operated from this state via the operation panel of the water heater, etc., the motor of the electric drive unit 6 is operated to rotate the gear member 6b, and the meshing portion 14a that meshes with the gear member 6b. The pinion member 14 moves in the direction in which the locking stepped portion 14b of the pinion member 14 contacts the stepped portion 4a of the second operating body 4, and the operating body is operated in the same manner as when the 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 operates to maintain and fix the inner wire 11b in the advanced state. By this operation, the end of the inner wire 11b on the side of the valve shaft 11c protrudes, and the valve member 7 is maintained and fixed in a state of being pushed up, so that the drain port 8a is opened as shown in FIG. When waste water or hot water is collected or flows into the tank body, it passes through the drain port 8a, the drain port main body 8, and the joint member 10, and is discharged from the drain port 10a to the sewage side. When the electric drive mechanism 6a detects that the above operation has been performed, the electric drive mechanism 6a reversely rotates the motor to retract the pinion member 14 to the initial position.
From this state, when the drain port 8a is operated again via the operation panel of the water heater, etc., the motor of the electric drive unit 6 is also operated to rotate the gear member 6b, and the gear member 6b is engaged with the gear member 6b. The pinion member 14 having the portion 14a moves in the direction in which the locking stepped portion 14b of the pinion member 14 comes into contact with the stepped portion of the second operating body 4, and the operating body operates in the same manner as when the pushing operation is applied. Let 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. It retreats to the operating portion 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, the pinion member 14 also rotates in the reverse direction and moves back to the initial position when it is determined that the pushing operation is completed, so that the operation of the operating body is not hindered.
Thereafter, by repeating the opening and closing operation to the drain port 8a by electric operation, the drain port 8a can be opened and closed by operating an operation panel or the like spaced apart 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, when the drain port 8a is open, the operation body moves forward, and when the drain port 8a is closed, the operation body moves backward. 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. Using the function of detecting 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 and the state of the drain port 8a detected by the sensor is the open state, the water heater is operated. It is also possible to configure such that the panel automatically instructs 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。 In addition, because of the structure described above, in the opening and closing operation of the drain port 8a, the procedure for opening and closing the drain port 8a can be performed according to any procedure, such as only manual operation, only electric operation, or a mixture of electric and manual operations. . That is, the drain port 8a can be opened freely without restrictions such that when the drain port 8a is opened by manual operation, it must be closed by manual operation, and when the drain port 8a is opened by electric operation, it 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 operating portion S or performing work inside the operating portion S due to a failure or the like, the operating button 13 is removed from the operating portion S first. In this case, the operation button 13 and the opening 1a can be 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 operation button 13 can be removed from the operation portion S by releasing the elastic fitting with the one operation body 3 . As described above, the fitting strength of the elastic fitting between the first operating body 3 and the operating button 13 depends on the elastic fitting strength of the first operating body 3 and the second operating body 4 and the holding strength of the second operating body 4 . Since it is weaker than the elastic fitting strength of the shaft 5b, the elastic fitting parts other than the first operation body 3 and the operation button 13 will not be 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 in the first operating body 3 causing 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 resolved by the above method, the rib piece 3a of the operating body 3 is used as a 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 concavities and convexities that match each other, when the first operating body 3 is rotated, the second operation is performed accordingly. The body 4 also rotates, and this intentional rotation disengages the stepped portion 4a of the second operating body 4 from the locking stepped portion 14b of the pinion member 14 .

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 performing the above measures, the repair procedure will change depending on the failure situation.
When the first operating body 3 is to be removed from the operating portion S, the first operating body 3 is pulled up from the opening 1a and removed from the operating portion S. In this case, first, the elastic engagement between the second operating body 4 and the holding shaft 5b of the lock mechanism 5 is released due to the difference in the strength of the elastic engagement. In some cases, it may be necessary to fix the holding shaft 5c of the lock mechanism 5 in a downwardly advanced state in order to secure a distance necessary for the release operation. Next, by releasing the elastic engagement between the first operating body 3 and the second operating body 4, the first operating body 3 is removed from the opening 1a. Since the second operating body 4 cannot be removed from the operating section 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 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 up to a level that cannot be reached in normal use, damage or the like may occur inside the operating portion S. 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 repairing, when the operating portion main body S1 is separated from the bathtub B, that is, separated from the first casing 1 attached to the bathtub B, the connection between the operating portion main body S2 and the first casing 1 is replaced by a connecting member. By detaching C3, it is possible to release and separate the operation portion main body S1 from the first casing 1. As shown in FIG. At this time, the operation portion main body S1 is separated from the bathtub B while the first operation portion 3 is connected to the operation portion main body S1 side, or the first operation portion 3 is taken out in advance and the operation portion main body S1 is removed from the bathtub B. The worker can freely select whether or not to perform the work of paragraphs 0020 and 0021 by performing/not performing the work.

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, when the second casing 2 is to be separated from the operation portion main body S1 in the course of repair, the connection between the operation portion main body S2 and the second casing 2 is released by detaching the connection member C3, and the operation portion main body is disconnected. S2 can be separated from the first casing 1 .
At this time, after releasing the engagement between the stepped portion 4a of the second operating body 4 and the engaging stepped portion 14a of the pinion member 14, the first operating body 3 is fully pulled up, thereby holding the second operating body 4. The elastic fitting of the shaft 5b can be released. At this time, whether or not to release the elastic engagement between the first operating body 3 and the second operating body 4 is determined by the operator depending on the situation.
As described above, the stress required to release the elastic engagement between the first operating body 3 and the second operating body 4 is greater 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. . As described above, when the second casing 2 is separated from the operation portion main body S2, the elastic engagement between the operation body and the holding shaft 5b is released in advance by operating the opening portion 1a. 2 can be easily performed.
After removing the operation button 13 as described above, it is possible to adjust the connection state of the operating body during the repair work by working 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。
Although the embodiments of the present invention are as described above, the present invention is not limited to the above embodiments, and can be freely modified without changing the gist of the invention.
For example, the above-described first embodiment is a remote operated drain plug device for both manual and electric use, and the lock mechanism 5 is arranged between the release wire 11, which is an operation transmission member, and the operating body. The invention is not limited to the above embodiments, and as shown in FIG. 10, in a manually-only remote-operated drain plug device, the operation body and the end of the release wire are configured to be connected by direct fitting. can be
In the remote control drain plug device shown in FIG. 10, the operating button 13 is fitted with the upper end of the operating body, and the lower end of the operating body is fitted with the upper end of the release wire 11b of the inner wire 11. As shown in FIG. At this time, the operating button 13 and the operating body O, and the operating body O and the end of the inner wire 11 can be fitted together by pressing them by elastic fitting, and can be released by pulling them apart. In the embodiment of FIG. 10, the strength of the elastic engagement, that is, how much stress must be applied in the separating direction to release the engagement between the members when they are pulled apart, is determined by elastic engagement between the operating body O and the inner wire 11b. is stronger than the stress for releasing the elastic engagement between the operating body O and the button member 13 . The engagement between the release wire 11 and the second casing 2 is sufficiently stronger than the engagement between the operation button 13 and the operation body O, or between the operation body O and the inner wire 11b. In the work of (2), the engagement between the release wire 11 and the second casing 2 cannot be released.
Further, the lock mechanism 5 is incorporated inside the support member 9 inside the drain port side 8a (not shown), and when the operation button 13 is pushed, the operation is performed by the operating body O and the inner wire 11b of the release wire 11. Each time the operation button 13 is operated, the valve member 7 is raised to maintain the state of opening the drain port 8a, fix / release the fixation, and the valve member 7 is lowered to lower the drain port. 8a can be operated repeatedly. Also, if a failure or the like occurs, as in the first embodiment, the operation button 13 can be removed first to check the inside thereof, and then the countermeasures can be taken. As described above, since the strength of elastic fitting between the operating body O and the inner wire 11b is stronger than the strength of elastic fitting between the operating body O and the operation button 13, the elastic fitting between the operating body O and the inner wire 11b may be erroneously broken. Only the elastic engagement of the operation button 13 can be reliably released without releasing.
After that, if necessary, the operating body O can be taken out from the opening 1a, or a jig or the like can be used to release the release wire 11 from the operating part S and take it out.

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-described embodiment, the method of fitting the operation button 13 and the operation body O, the operation body O and the end of the inner wire 11b of the release wire 11 that is the operation transmission member, or the holding shaft 5b that is the shaft portion of the lock mechanism 5 or the fitting method of the first operation body 3 and the second operation body 4, which are the operation bodies O, is limited to elastic fitting using resin elasticity or the like. It is not limited to the embodiment, and fitting can be performed only by applying stress in the axial direction, such as elastic fitting via a member such as an O-ring, fitting using surface friction or the like. Any fitting method may be adopted as long as it is a method of fitting in which 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-described embodiment, and the washbowl of the washbasin and the sink. It may be incorporated in a sink or the like for use.
