Description

【0001】
【発明の属する技術分野】
本発明は、洗面器、浴槽などの槽体の排水口の開閉を遠隔操作する、遠隔操作式排水栓装置に関するものである。
【0002】
【従来の技術】
従来よく知られた、浴槽等に取り付けられる遠隔操作式排水栓装置としては、例えば図1に示した浴槽において、図8に示した操作部を採用したものがある(例えば、特許文献1参照)。以下に図8に示した操作部を用いた遠隔操作式排水栓装置の従来例を、図面を参照にしつつ説明する。
図8に図示した操作部を採用した従来例の遠隔操作式排水栓装置は、以下に記載した排水栓、弁体、レリースワイヤ、操作部、排水栓受け部材としてのエルボ部材、チューブ管、より構成されてなる。
排水栓は、内部に排水口を形成する略円筒形状であって、その外側面にねじを備えて成る。
弁体は、上記排水口を閉口する部材である。
レリースワイヤは、可撓性を備えた中空のアウターチューブと、該アウターチューブの内面を軸方向に摺動するインナーワイヤと、から成る。
操作部は、以下に記載するスイッチケーシングと、操作ボタンと、スラストロック機構を内蔵した保持機構部と、から成る。
スイッチケーシングは、円筒形状にして内面に凸設された段形状の載置部を備えて成り、更にその内部には、上方から順に後記する操作ボタン、保持機構部、を収納してなる。
操作ボタンは、使用者がこれを手で押しこむことによって、その駆動をレリースワイヤへ伝達するための部品であり、下部は保持機構部の動作軸に取り付け固定されてなる。
保持機構部は、その内部に、公知であるノック式ボールペンなどのロック機構等に用いられるスラストロック機構を備え、その外側面上方に、スイッチケーシングの載置部に係止される鍔部を備えるとともに、その中心に、前記操作ボタンの押しこみ操作毎に前進(降下)して固定/固定を解除しレリースワイヤのインナーワイヤに付勢されて後退(上昇)、を繰り返す動作軸を備えてなる。
エルボ部材は、排水栓のねじと螺合するねじを設け、排水栓の排水口と連通する開口を備えて成る。また、排水口から流れ込む排水を下水側に排出するための排水用の開口、及びレリースワイヤを相通する接続口を備えて成る。
チューブ管は、筒状にして軸方向には剛性を、また側面方向には可撓性を備えた中空の部材であって、一方の端部は前記操作部のスイッチケーシング下端外周面に、他端はエルボ部材の接続口にそれぞれ水密的に接続され、内部にはレリースワイヤが挿通されてなる。
【0003】
上記のように構成した遠隔操作式排水栓装置を図1に図示した浴槽に取り付ける場合、まず、浴槽等に設けた排水栓取付用の開口の周縁を介して排水栓とエルボ部材を螺合させ、浴槽の開口に排水栓を取り付ける。
次に、浴槽上縁部に設けられた取付孔に、操作部のスイッチケーシングを取り付け固定し、更にスイッチケーシングの下端と前記エルボ部材の挿通口とを、前記チューブ管を介して水密的に接続する。
更にレリースワイヤを、スラストロック機構に連動するようにして保持機構部に接続し、保持機構部の鍔部がスイッチケーシングの載置部上に係止するまで挿入すると、レリースワイヤはチューブ管、接続口を介し、エルボ部材内に挿通される。更に浴槽の上方側から、エルボ部材内に配置しているレリースワイヤの先端を、排水口を通してペンチなどで浴槽側へ引き上げる。
この状態より、排水口より引き上げたレリースワイヤの端部を弁体に連結させて、レリースワイヤの排水口側端部を弁体の直下となるように配置することで遠隔操作式排水栓装置の取り付けが完了する。
【0004】
この従来例の遠隔操作式排水栓装置を使用する場合、まず操作部の操作ボタンに操作を加えて弁体が排水口を閉口した状態、即ちレリースワイヤのインナーワイヤが操作部側に後退した状態とする。この状態より操作ボタンに操作を加えて、インナーワイヤを排水口側に前進させると、インナーワイヤ先端が上昇して直上にある弁体を押上げ、排水口を開口する。この開口状態は操作部に備えた保持機構部のスラストロック機構によって維持される。この状態より操作ボタンに操作を加えてスラストロック機構の維持状態を解除すると、インナーワイヤが操作部側に後退するため、レリースワイヤによって押し上げられていた弁体も降下して排水口を閉口する。以後この操作を繰り返すことで排水口の開閉を自在に操作することができる。

【発明が解決しようとする課題】
上記したような遠隔操作式排水栓装置においては、以下の作用を得る為に操作部とエルボ部材との間にチューブ管を介して接続されている。このため、
1.前記操作部のスイッチケーシング内に侵入した排水をチューブ管を通して直接エルボ部材から下水側へ排水することができ、浴槽下に垂れ流しにならず浴槽下が汚れることが無い。
2.上記の遠隔操作式排水栓装置の施工の際や、メンテナンスの際に、チューブ管がレリースワイヤの案内通路となるので、円滑にレリースワイヤをエルボ部材側まで案内でき、狭い浴槽下などにもぐりこむことなく作業することが出来る。これは特に浴槽一式の施工が終了し、防水パンや浴槽の裏側から作業を行うことが出来ないメンテナンス時に効果的である。
【0007】
ところで、このレリースワイヤの、スイッチケーシング、チューブ管、エルボ部材の長さによって決定される、遠隔操作式排水栓装置の施工に最低限必要となるレリースワイヤの長さ(以後、単に「必要長さ」と記載)に対して、実際に施工に使用されるレリースワイヤが短かすぎると、当然操作部からエルボ部材側までの間をレリースワイヤで接続することが不可能である。しかしながら、レリースワイヤが長すぎると余分な長さのレリースワイヤがチューブ管内で捻れたり、無理な曲がり方をしてレリースワイヤを破損させてしまう、といった問題がある。このような理由から、通常遠隔操作式排水栓装置のレリースワイヤは、必要長さ以上の余分な長さ分(以下、単に「あそび長さ」と記載)がほとんど生じないように寸法調整を行っている。
【0008】
一方で上記のような遠隔操作式排水栓装置においては、レリースワイヤを弁体に接続する際に、浴槽上方の排水口から浴槽内に一旦レリースワイヤを引き上げて、レリースワイヤの排水口側端部を弁体に接続する必要があり、この場合にはあそび長さが長い方がレリースワイヤの浴槽内への飛び出し長さも長くなり、施工が容易となる。
しかし、前記段落0007に記載したように、実際にはレリースワイヤにはあそび長さがほとんどないため、排水口から引き出すことが出来るレリースワイヤの長さもごくわずかであり、この接続作業の作業者は浴槽の中に身を乗り出して浴槽の底とレリースワイヤの飛び出しのわずかな隙間で作業を行わなければならず、大変施工作業が不便であった。また、この困難さから、作業者がレリースワイヤを無理に引っ張り出そうとして過大な引っ張り力を加えてしまうことがあり、レリースワイヤの損傷の一因となっていた。
【0009】
更なる問題として、前記したスイッチケーシングの内面と保持機構部の側面との間には隙間がほとんどないため、スイッチケーシング内に排水が流入した場合に、保持機構部に内蔵しているスラストロック機構内部を通過してエルボ部材側へと排水していた。このため、内部の動作軸などの動作を行う部分に排水が流入して排水中の汚濁物質が付着し、故障や誤作動の原因となっていた。
【0010】
本発明は上記のような問題を解決するために発明されたものであって、
ア.遠隔操作式排水栓装置の取り付け作業の作業性を向上させ、レリースワイヤの損傷や挫屈を防止する。
イ.保持機構部の排水流入による保持機構部の故障、誤作動防止、を目的とする。
【0011】

【0017】
【実施例】
以下に本発明の第1実施例を、図面を参照しつつ説明する。
図2乃至図5に図示した、本発明の操作部を採用した遠隔操作式排水栓装置は、以下に記載した排水栓(9)、弁体(2)、レリースワイヤ(5)、操作部(S)、排水栓受け部材としてのエルボ部材(7)、チューブ管(8)、図6及び図7に図示した引き上げ用治具(Z)より構成されてなり、図1に図示した浴槽(B)に採用されてなる。
排水栓(9)は、内部に排水口(1)を形成する略円筒形状であって、その外側面にねじを備えて成る。
弁体(2)は、上記排水口(1)を閉口する部材である。
レリースワイヤ(5)は、可撓性を備えた中空のアウターチューブ(5b)と、該アウターチューブ(5b)の内面を軸方向に滑動するインナーワイヤ(5a)と、から成るとともに、インナーワイヤ(5a)の操作部側端部は後記するスラストロック機構の動作軸と一体的に構成されてなる。
操作部(S)は、以下に記載するスイッチケーシング(3)と、操作ボタン(10)と、引き上げナット(4)と、保持機構部(6)と、から成る。
スイッチケーシング(3)は、円筒形状にして内面に円周に沿って凸設された段形状の載置部(3a)と、内周面の軸方向溝状に刻設された位置決め受け部(3b)と、上面視位置決め部(6b)と交互となるように、位置決め受け部(3b)の下方に軸方向溝状に刻設してなる爪受け部(3c)と、から構成され、その内部に、上方から順に後記する操作ボタン(10)、保持機構部(6)、引き上げナット(4)を収納してなる。
操作ボタン(10)は、使用者がこれを手で押しこむことによって、その駆動をレリースワイヤ(5)のインナーワイヤ(5a)へ伝達するための部品であり、下部は後記するスラストロック機構の動作軸に取付固定されてなる。
保持機構部(6)は内部にスラストロック機構を内蔵する部材であって、上端部に傘状の突起からなる係合部(6d)を設け、また外周面には雄ねじ(6a)を設けると共に、雄ねじ(6a)の更に下方の外周面に、前記スイッチケーシング(3)の位置決め受け部(3b)の溝に嵌ることでスイッチケーシング(3)に位置決めされる位置決め部(6b)と、位置決め部(6b)の更に下方に、上面視位置決め部(6b)と重ならないように脚状に設けられ、前記スイッチケーシング(3)の爪受け部(3c)に当接する抜け防止爪(6c)と、から構成される。
保持機構部(6)に内蔵されているスラストロック機構は、図示しないがノック式ボールペンや従来の遠隔操作式排水栓装置などのロック機構等に用いられている公知の機構であって、その中心に、前記操作ボタン(10)の押しこみ操作毎に前進(降下)して固定/固定を解除しレリースワイヤ(5)のインナーワイヤ(5a)に付勢されて後退(上昇)、を繰り返す動作軸を備えてなる。更に、図示しないが後記するレリースワイヤ(5)のインナーワイヤ(5a)端部は該動作軸と一体的に構成されてなる。
引き上げナット(4)は、円筒形状であって、外側面にスイッチケーシング(3)の載置部(3a)に載置される鍔部(4c)を有し、かつ内周面には前記した保持機構部(6)の雄ねじ(6a)と螺合する、雌ねじ(4a)を二重螺旋状に設けている。また、引き上げナット(4)上端には、上面視外周方向から中心部に向かって延びたアームを適宜設けて、前記保持機構部(6)の係合部(6d)と係合する被係合部(4b)を設けて成る。
上記の引き上げナット(4)と保持機構部(6)とは、それぞれのねじ部(雄ねじ(6a)及び雌ねじ(4a))の形状を、ねじ山同士の間隔をねじ山の幅以上の幅とするとともに、ねじ山を2重螺旋状に設け、また引き上げナット(4)及び保持機構部(6)のねじ部の上下をそれぞれ通水可能に隙間(11)を設けて解放してなる。具体的にこの実施例では、螺合時にねじ山一つ分の隙間が生じるように形成されて成り、この隙間を、スイッチケーシング(3)内に進入した排水を排出するための通水隙間(11)として利用してなる。
エルボ部材(7)は、排水栓(9)のねじと螺合するねじを設け、排水栓(9)の排水口(1)と連通する開口を備えて成る。また、排水口(1)から流れ込む排水を下水側に排出するための排水用の開口、及びレリースワイヤ(5)を挿通する接続口(7a)を備えて成る。
チューブ管(8)は、筒状にして軸方向には剛性を、また側面方向には可撓性を備えた中空の部材であって、一方の端部は前記操作部(S)のスイッチケーシング(3)下端外周面に、他端はエルボ部材(7)の接続口(7a)にそれぞれ水密的に接続され、内部にはレリースワイヤ(5)が挿通されてなる。
引き上げ用治具(Z)は、図6及び図7に示したように、スイッチケーシング(3)の内部で引き上げナット(4)を回動させることで引き上げナット(4)を引き上げるもので、前記スイッチケーシング(3)の上端開口の円筒内周よりも小径な外周面を有する筒状体(13)から成り、該筒状体(13)には、一方の開口に設けた前記引き上げナット(4)の鍔部(4c)と嵌合する切欠形状に設けられた嵌合部(13a)と、筒状体(13)の他方の端部の外周面を、遠隔操作式排水栓装置の排水口(1)の内周面よりも小径とすると共に、該他方の端部に、概略中空の球体を四半分とした形状であって、筒状体の軸方向と、該軸方向の垂直となる方向とを内面において滑らかに連通する、レリースワイヤ(5)のガイド部(13b)を設けて成る。
また、この引き上げ用治具(Z)には、その側面にスイッチケーシング(3)や排水口(1)の開口よりも大径な落下防止リブ(13c)を設けて成り、引き上げ用治具(Z)がスイッチケーシング(3)や排水口(1)から下方に落下することを防止している。
尚、当然のことながら、該落下防止リブ(13c)から嵌合部(13a)までの長さはスイッチケーシング(3)の開口から引き上げナット(4)が配置される載置部(3a)までの距離よりも長く形成されている。
また、落下防止リブ(13c)からガイド部(13b)までの長さは排水栓(9)の開口から下端までの長さよりも長く形成されている。即ち、図7に示したように落下防止リブ(13c)を排水口(1)に当接させた時にはガイド部(13b)は排水栓(9)の開口を貫通し、排水栓(9)の下端から突出する構造となる。
尚、本発明においては、施工時に、前述した引き上げナット(4)の雌ねじ(4a)と、保持機構部(6)の雄ねじ(6a)とが螺合することによって、レリースワイヤ(5)の先端から、引き上げナット(4)までの長さが短く収縮するように構成されて成る。引き上げナット(4)は、鍔部(4c)がスイッチケーシング(3)の載置部(3a)上に当接して、スイッチケーシング(3)の軸方向に対して位置決めされるため、結局は螺合によってレリースワイヤ(5)が操作部(S)側に後退する。本実施例では、この螺合を完了した状態において、レリースワイヤ(5)の、排水口(1)からのレリースワイヤ(5)の飛び出し長さが、遠隔操作式排水栓装置の作動に適切となる長さになるよう、レリースワイヤ(5)の全長が調整されてなる。
【0018】
上記のように構成した遠隔操作式排水栓装置を、図1に図示した浴槽(B)に取り付ける場合、まず、浴槽(B)等に設けた排水栓取付用の開口の周縁を介して排水栓とエルボ部材(7)を螺合させ、浴槽の開口に排水栓(9)を取り付ける。
次に、浴槽(B)上縁部に設けられた取付孔に、操作部(S)のスイッチケーシング(3)を取り付け固定し、更にスイッチケーシング(3)の下端と前記エルボ部材(7)の接続口(7a)とを、前記チューブ管(8)を介して水密的に接続する。
更に図3に示したようにレリースワイヤ(5)を、保持機構部(6)に接続した上で、保持機構部(6)の位置決め部(6b)がスイッチケーシング(3)の位置決め受け部(3b)に嵌ってスイッチケーシング(3)に係止するまで挿入すると、レリースワイヤ(5)はチューブ管(8)、接続口(7a)を介し、エルボ部材(7)内に挿通される。更に浴槽(B)の上方側から、エルボ部材(7)内に配置しているレリースワイヤ(5)の先端を、排水口(1)を通して浴槽(B)側へ引き上げる。
このレリースワイヤ(5)を排水口(1)から引き上げる際には、前記した引き上げ用治具(Z)のガイド部を、図7に示したように排水口(1)内に挿入する。このようにすることで、レリースワイヤ(5)の先端が引き上げ用治具(Z)のガイド部(13b)に当接し、上方に突出するため、わざわざ狭い排水口(1)内に指やペンチを使用せずにレリースワイヤ(5)を浴槽(B)空間内まで簡単に引き出すことが可能である。
このとき、レリースワイヤ(5)の浴槽(B)内への飛び出し長さは、雌ねじ(4a)と雄ねじ(6a)とが螺合を完了した状態において、排水口(1)からのレリースワイヤ(5)の飛び出し長さが遠隔操作式排水栓装置の作動に適切となる長さになるようにレリースワイヤ(5)の全長が調整されてなるため、雌ねじ(4a)と雄ねじ(6a)との螺合がほとんど行われていないこの状態においては、従来の遠隔操作式排水栓装置と比べて、螺合の長さ分だけ余分に浴槽(B)内に突出してなる。
この状態において、レリースワイヤ(5)の排水口(1)側の端部を弁体(2)に接続させる。
その後、スイッチケーシング(3)内に前記した引き上げ用治具(Z)の嵌合部(13a)と引き上げナット(4)の鍔部(4c)を嵌合させて引き上げ用治具(Z)を回転させると、引き上げナット(4)が引き上げ用治具(Z)の回転に併せて回転し、引き上げナット(4)の雌ねじ(4a)と保持機構部(6)の雄ねじ(6a)の螺合が進んで、保持機構部(6)が上昇して引き上げナット(4)に巻き上げられる形となる。この際には、位置決め部(6b)が、スイッチケーシング(3)の位置決め受け部(3b)の溝に収納された状態のため、雌ねじ(4a)と雄ねじ(6a)との間には、一方の回転の際による摩擦によって、他方のねじも回転し、螺合がそれ以上進行しなくなる共回り現象が生じることなく、図2のように両者の螺合を完成させることができる。
また、引き上げナット(4)と保持機構部(6)の各ねじ部のねじ山はそれぞれに2山設けられている。このため、螺合が容易に進行するようにねじのピッチを荒くし、例えば1回転で螺合が完了するように構成したり、通水隙間(11)形成のため、ねじ山同士の間隔をねじ山の幅以上の幅としても、両者の回転軸がずれることがないので、螺合不良を防止することができる。
また、螺合が完成すると同時に、引き上げナット(4)の被係合部(4b)に保持機構部(6)の係合部(6d)が係合するように構成されてなる。この係合は、係合部(6)の傘状の突起の下方に、被係合部(4b)のアームの先端が嵌り込むことで達成されるが、この係合時の衝撃もしくは衝撃音で施工している作業者は引き上げナット(4)の巻き上げの終了を知ることができる。また、上記雄ねじ(6a)と雌ねじ(4a)の螺合は、通水隙間(11)を形成し、両者の間にほとんど摩擦が生じないように構成されているため、通常のねじによる螺合とことなり、部材同士をつなぎ止めておくことはほとんど不可能であるが、この係合によって、引き上げナット(4)に保持機構部(6)を固定し、保持機構部(6)が引き上げナット(4)から脱落することを防止することができる。
また、この螺合が完成すると同時に、保持機構部(6)の抜け防止爪(6c)がスイッチケーシング(3)の爪受け部(3c)に係止される。これにより、例えば弁体(2)が開口時に強い衝撃が加わって、その衝撃がレリースワイヤ(5)を介して保持機構部(6)に伝達したとしても、保持機構部(6)が適正位置より飛び出すことがなくなる。
またこのとき、操作部(S)は、図5に図示したように、スイッチケーシング(3)内周面と、引き上げナット(4)の外周面に通水用の通路(12)を設けて配置し、更に、上面視位置決め受け部(3b)と重複しないように設けられた、抜け防止爪(6c)が嵌っていない爪受け部(3c)の隙間を通水用の通路(12)として解放したので、操作部(S)に侵入した排水は該通水用の通路(12)内を通過してエルボ部材(7)側へ円滑に排水することが出来、保持機構部(6)の故障や誤作動を防止することができる。
また、保持機構部(6)の雄ねじ(6a)と引き上げナット(4)の雌ねじ(4a)は、それぞれのねじ山とねじ山の間に沿って設けられた通水用の隙間(11)を設けているので、スイッチケーシング(3)内に排水が流入しても、排水は互いのねじ山に沿って排水用の隙間(11)を通過するので円滑にチューブ管(8)側へと排水を行うことができる。
この螺合が完了した状態において、レリースワイヤ(5)の、排水口(1)からのレリースワイヤ(5)の飛び出し長さが、遠隔操作式排水栓装置の作動に適切な長さになる。
その後、排水口(1)より引き上げたレリースワイヤ(5)の端部を弁体(2)に連結させて、排水口(1)側のレリースワイヤ(5)端部が弁体(2)の直下となるように配置することで遠隔操作式排水栓装置の取り付けが完了する。
【0019】
また、本実施例の遠隔操作式排水栓装置は、前記段落0004に記載した従来例と同様の方法によって使用することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a remote-operated drain plug device that remotely controls the opening and closing of drains of tank bodies such as basins and bathtubs.
[0002]
[Prior art]
As a well-known remote-operated drain plug device attached to a bathtub or the like, for example, in the bathtub shown in FIG. 1, there is one that employs the operation unit shown in FIG. 8 (see, for example, Patent Document 1). . Hereinafter, a conventional example of a remote-operated drain plug device using the operation unit shown in FIG. 8 will be described with reference to the drawings.
The remote control type drain plug device of the prior art adopting the operation section illustrated in FIG. 8 includes a drain plug, a valve body, a release wire, an operation section, an elbow member as a drain plug receiving member, a tube tube, and the like described below. Consists of.
The drain plug has a substantially cylindrical shape that forms a drain port therein, and includes a screw on the outer surface thereof.
The valve body is a member that closes the drain port.
The release wire includes a hollow outer tube having flexibility and an inner wire that slides in the axial direction on the inner surface of the outer tube.
The operation unit includes a switch casing described below, an operation button, and a holding mechanism unit incorporating a thrust lock mechanism.
The switch casing is provided with a cylindrical mounting portion that is formed in a cylindrical shape and protrudes on the inner surface, and further stores therein an operation button and a holding mechanism portion which will be described later in order from above.
The operation button is a part for transmitting the drive to the release wire when the user pushes it in by hand, and the lower part is attached and fixed to the operation shaft of the holding mechanism.
The holding mechanism portion includes a thrust lock mechanism used for a known lock mechanism such as a knock type ballpoint pen inside, and a hook portion that is locked to the placement portion of the switch casing above the outer surface thereof. In addition, at the center thereof, there is provided an operation shaft that repeats forward (lower) every time the operation button is pushed, fixed / unfixed, and urged by the inner wire of the release wire to retreat (up). .
The elbow member is provided with a screw that is screwed with the screw of the drain plug, and has an opening that communicates with the drain port of the drain plug. In addition, a drain opening for discharging waste water flowing from the drain port to the sewage side, and a connection port through which the release wire communicates are provided.
The tube tube is a hollow member that has a cylindrical shape and is rigid in the axial direction and flexible in the side direction. One end of the tube is on the outer peripheral surface of the lower end of the switch casing of the operation unit, and the other. The ends are connected to the connection ports of the elbow members in a watertight manner, and a release wire is inserted inside.
[0003]
When the remote-operated drain plug device configured as described above is attached to the bathtub illustrated in FIG. 1, first, the drain plug and the elbow member are screwed together through the peripheral edge of the drain plug mounting opening provided in the bathtub or the like. Attach a drain tap to the bathtub opening.
Next, the switch casing of the operation section is attached and fixed to the mounting hole provided in the upper edge of the bathtub, and the lower end of the switch casing and the insertion port of the elbow member are connected in a watertight manner through the tube pipe. To do.
Furthermore, the release wire is connected to the holding mechanism so as to interlock with the thrust lock mechanism, and is inserted until the hook of the holding mechanism is locked onto the mounting portion of the switch casing. The elbow member is inserted through the mouth. Further, from the upper side of the bathtub, the tip of the release wire disposed in the elbow member is pulled up to the bathtub side with pliers or the like through the drainage port.

No. 7-38420 (paragraph number 0011, second page of the text, FIG. 1)
[0006]
[Problems to be solved by the invention]
In the remote-operated drain plug device as described above, the operation unit and the elbow member are connected via a tube tube in order to obtain the following effects. For this reason,
1. The drainage that has entered the switch casing of the operation section can be drained directly from the elbow member to the sewage side through the tube tube, and does not run down under the bathtub and the bottom of the bathtub is not soiled.
2. When constructing and maintaining the above-mentioned remote-operated drain plug device, the tube tube serves as the guide wire for the release wire, so that the release wire can be smoothly guided to the elbow member side and can be pulled under a narrow bathtub. You can work without. This is particularly effective during maintenance when the construction of the set of bathtubs is completed and work cannot be performed from the back side of the waterproof pan or bathtub.
[0007]
By the way, the length of the release wire, which is determined by the length of the switch casing, the tube tube, and the elbow member, which is the minimum required for the construction of the remote-operated drain plug device (hereinafter simply referred to as “required length”). In contrast, if the release wire actually used for the construction is too short, it is naturally impossible to connect the operation portion to the elbow member side with the release wire. However, if the release wire is too long, an excessive length of the release wire may be twisted in the tube tube, or may be bent excessively and damage the release wire. For this reason, the release wire of a remote-controlled drain plug device is usually sized so that there is almost no extra length beyond the required length (hereinafter simply referred to as “play length”). ing.
[0008]
On the other hand, in the remote control type drain plug device as described above, when connecting the release wire to the valve body, the release wire is once pulled up from the drain port above the bathtub into the bathtub, and the drain wire side end of the release wire In this case, the longer the play length, the longer the release wire protrudes into the bathtub, and the construction becomes easier.
However, as described in the paragraph 0007, since the release wire actually has almost no play length, the length of the release wire that can be pulled out from the drain outlet is very small. The work had to be carried out in a small gap between the bottom of the bathtub and the release wire jumping out, and the construction work was very inconvenient. In addition, due to this difficulty, an operator may apply an excessive pulling force to forcefully pull out the release wire, which causes damage to the release wire.
[0009]
As a further problem, since there is almost no gap between the inner surface of the switch casing and the side surface of the holding mechanism, the thrust lock mechanism built in the holding mechanism when drainage flows into the switch casing. Drained to the elbow member side through the inside. For this reason, the wastewater flows into the part that performs the operation such as the internal operation shaft, and the pollutant in the wastewater adheres, causing a failure or malfunction.
[0010]
The present invention was invented to solve the above problems,
A. Improve the workability of installing the remote control drain plug device, and prevent damage and buckling of the release wire.
I. The purpose is to prevent the malfunction and malfunction of the holding mechanism due to the drainage of the holding mechanism.

(3) The other end of the lower end outer peripheral surface is watertightly connected to the connection port (7a) of the elbow member (7), and the release wire (5) is inserted inside.
As shown in FIGS. 6 and 7, the lifting jig (Z) lifts the lifting nut (4) by rotating the lifting nut (4) inside the switch casing (3). The switch casing (3) is composed of a cylindrical body (13) having an outer peripheral surface smaller in diameter than the cylindrical inner periphery of the upper end opening. The cylindrical body (13) includes the lifting nut (4) provided in one opening. ), The fitting portion (13a) provided in a notch shape to be fitted to the collar portion (4c), and the outer peripheral surface of the other end portion of the cylindrical body (13) are connected to the drain port of the remote-operated drain plug device.

The lifting jig (Z) is provided with drop prevention ribs (13c) having a diameter larger than that of the opening of the switch casing (3) and the drain port (1) on the side surface thereof. Z) prevents the switch casing (3) and the drain port (1) from falling downward.
Of course, the length from the fall prevention rib (13c) to the fitting portion (13a) is from the opening of the switch casing (3) to the mounting portion (3a) where the lifting nut (4) is disposed. It is formed longer than the distance.
Moreover, the length from the fall prevention rib (13c) to the guide part (13b) is formed longer than the length from the opening of the drain plug (9) to the lower end. That is, as shown in FIG. 7, when the fall prevention rib (13c) is brought into contact with the drain port (1), the guide portion (13b) penetrates the opening of the drain plug (9), and the drain plug (9) The structure protrudes from the lower end.
In the present invention, at the time of construction, the female screw (4a) of the pulling nut (4) and the male screw (6a) of the holding mechanism (6) are screwed together, so that the tip of the release wire (5) To the lifting nut (4) is configured to be contracted short. The lifting nut (4) is positioned with respect to the axial direction of the switch casing (3) because the flange portion (4c) abuts on the mounting portion (3a) of the switch casing (3). As a result, the release wire (5) moves backward toward the operation unit (S). In this embodiment, when the screwing is completed, the length of the release wire (5) protruding from the drain outlet (1) of the release wire (5) is appropriate for the operation of the remote-operated drain plug device. The total length of the release wire (5) is adjusted so that the length becomes.
[0018]
When the remote-operated drain plug device configured as described above is attached to the bathtub (B) illustrated in FIG. 1, first, the drain plug is inserted through the peripheral edge of the drain plug mounting opening provided in the bathtub (B) or the like. And the elbow member (7) are screwed together, and a drain plug (9) is attached to the opening of the bathtub.
Next, the switch casing (3) of the operation section (S) is mounted and fixed in the mounting hole provided in the upper edge of the bathtub (B), and the lower end of the switch casing (3) and the elbow member (7) are fixed. The connection port (7a) is watertightly connected via the tube pipe (8).
Further, as shown in FIG. 3, after the release wire (5) is connected to the holding mechanism portion (6), the positioning portion (6b) of the holding mechanism portion (6) is moved to the positioning receiving portion ( When it is inserted until it is fitted to 3b) and locked to the switch casing (3), the release wire (5) is inserted into the elbow member (7) through the tube tube (8) and the connection port (7a). Further, from the upper side of the bathtub (B), the tip of the release wire (5) arranged in the elbow member (7) is pulled up to the bathtub (B) side through the drain port (1).
When the release wire (5) is pulled up from the drain port (1), the guide portion of the lifting jig (Z) is inserted into the drain port (1) as shown in FIG. By doing so, the tip of the release wire (5) comes into contact with the guide portion (13b) of the lifting jig (Z) and protrudes upward, so that a finger or pliers is purposely placed in the narrow drainage port (1). It is possible to easily pull out the release wire (5) into the bathtub (B) space without using the.
At this time, the length of protrusion of the release wire (5) into the bathtub (B) is such that the release wire (1) from the drain port (1) in a state where the female screw (4a) and the male screw (6a) have been screwed together. Since the total length of the release wire (5) is adjusted so that the protruding length of 5) is appropriate for the operation of the remote-operated drain plug device, the female screw (4a) and the male screw (6a) In this state where the screwing is hardly performed, compared to the conventional remote-operated drain plug device, it protrudes into the bathtub (B) by the length of the screwing.
In this state, the end of the release wire (5) on the drain outlet (1) side is connected to the valve body (2).
Thereafter, the fitting portion (13a) of the lifting jig (Z) and the flange portion (4c) of the lifting nut (4) are fitted into the switch casing (3), and the lifting jig (Z) is fitted. When rotated, the pulling nut (4) rotates in accordance with the rotation of the pulling jig (Z), and the female screw (4a) of the pulling nut (4) and the male screw (6a) of the holding mechanism (6) are screwed together. Then, the holding mechanism portion (6) rises and is wound up on the lifting nut (4). At this time, since the positioning portion (6b) is housed in the groove of the positioning receiving portion (3b) of the switch casing (3), there is one between the female screw (4a) and the male screw (6a). The other screw is also rotated by the friction caused by the rotation of the screw, and the screwing of the two screws can be completed as shown in FIG.
Moreover, the thread of each thread part of a raising nut (4) and a holding mechanism part (6) is provided in two each. For this reason, the pitch of the screw is made rough so that the screwing can easily proceed, and for example, the screwing is completed by one rotation, or the gap between the threads is made to form the water passage gap (11). Even if the width is equal to or greater than the width of the screw thread, the rotational axes of the two do not deviate, so that poor screwing can be prevented.
Further, at the same time as the screwing is completed, the engaging portion (6d) of the holding mechanism portion (6) is engaged with the engaged portion (4b) of the pulling nut (4). This engagement is achieved by fitting the tip of the arm of the engaged portion (4b) below the umbrella-shaped protrusion of the engaging portion (6). The worker who is constructing in can know the end of the winding of the lifting nut (4). Further, since the male screw (6a) and the female screw (4a) are screwed together so as to form a water passage gap (11) and hardly cause friction between them, the screwing by a normal screw is used. Therefore, it is almost impossible to keep the members connected to each other, but by this engagement, the holding mechanism portion (6) is fixed to the lifting nut (4), and the holding mechanism portion (6) is fixed to the lifting nut. It is possible to prevent dropping from (4).
Further, at the same time as the screwing is completed, the removal preventing claw (6c) of the holding mechanism portion (6) is locked to the claw receiving portion (3c) of the switch casing (3). Thus, for example, even if a strong impact is applied when the valve body (2) is opened and the impact is transmitted to the holding mechanism portion (6) via the release wire (5), the holding mechanism portion (6) is in the proper position. No more jumping out.
At this time, as shown in FIG. 5, the operation portion (S) is provided with a water passage (12) provided on the inner peripheral surface of the switch casing (3) and the outer peripheral surface of the lifting nut (4). Furthermore, the clearance of the nail holder (3c) provided so as not to overlap with the positioning receiving part (3b) when viewed from above is not fitted as a passage for water (12). As a result, the drainage that has entered the operation section (S) can pass through the passage (12) and smoothly drain to the elbow member (7) side, and the holding mechanism section (6) fails. And malfunction can be prevented.
Further, the male screw (6a) of the holding mechanism section (6) and the female screw (4a) of the lifting nut (4) have a water passage gap (11) provided between the respective screw threads. Even if drainage flows into the switch casing (3), the drainage passes through the drainage gap (11) along the thread of each other, so the drainage smoothly flows to the tube tube (8) side. It can be performed.
In a state where the screwing is completed, the length of the release wire (5) protruding from the drain port (1) of the release wire (5) becomes a length suitable for the operation of the remote-operated drain plug device.
Thereafter, the end of the release wire (5) pulled up from the drain (1) is connected to the valve body (2), and the end of the release wire (5) on the drain (1) side is connected to the valve (2). Installation of the remote-operated drain plug device is completed by placing it directly below.
[0019]
Further, the remote-operated drain plug device of the present embodiment can be used by the same method as the conventional example described in paragraph 0004 above.
[0020]
The remote-operated drain plug device of the present invention is as described above, but the present invention is not limited to the above-described embodiments, and can be appropriately changed within the scope described in the claims.
