Description
【０００１】
【発明の属する技術分野】
本発明は、浴槽を載置する防水パンに取り付けられる排水装置の、排水口に備えられるカバー部材に関するものである。
【０００２】
【従来の技術】
従来より、浴室など、槽体を載置した防水パンの排水口には、配管上の必要性や、排水の逆流防止の目的から、様々な機能を付加されたカバー部材が備えられている。
図５に示した浴室配管の場合、
防水パンを、浴槽を載置する載置部（特開平１０−１６８９７２号の「浴槽設置部」に相当）と、使用者が身体を洗う等する洗い場部とに分割し、
洗い場部には排水トラップを、載置部には排水部をそれぞれ備え、且つ両者をパイプ管等にて接続して、排水部からの排水を排水トラップにて処理できるように構造している。
更に排水部に、浴槽からの排水が流入する第二排水孔と、載置部上の排水を行う、逆流防止弁を備えた第一排水孔を備えたカバー部材（特開平１０−１６８９７２号の「集水板」に相当）を配置して、洗い場部上面から浴槽上縁までの高さ（以後「またぎ高さ」と呼ぶ）が低い配管構造を提供している（例えば、特許文献１）。
【０００３】
更にこれらの配管構造において、浴槽の排水口を、浴槽の縁部に設けた操作部に操作を加えることで自在に開閉する、遠隔操作式排水栓装置が知られている。図６に示した遠隔操作式排水栓装置の場合、浴槽に取り付けられた排水栓と、防水パン上の排水口との接続を行う排水継手の側面から、操作部に加えられた操作の伝達を行う操作伝達部材の一種であるレリースワイヤを挿通して、浴槽配管における、遠隔操作式排水栓装置の施工を行っている（例えば、特許文献２）。
【０００４】
また、上記段落０００３に記載された操作伝達部材の挿通方法とは別の方法として、図７に示した遠隔操作式排水栓装置の場合、防水パン上に、排水口とは別途の操作伝達部材用の挿通口とそれに続く配管部材を配設し、それらを介して、操作伝達部材を防水パン上から排水装置の内部に挿通し、遠隔操作式排水栓装置の施工を行っている（例えば、特許文献３）。

【発明が解決しようとする課題】
上記したまたぎ高さが高いと、乗り越えなければならない壁面が高くなることから、使用者にとっては浴槽が利用し難いものとなってしまう。このため、このまたぎ高さをなるべく低くすることが近年の浴室配管の重要な課題となっている。
しかしながら、浴槽を浅くすることでまたぎ高さを低くすると、浴湯の量が少なく、また浴槽の使用者が全身を浴湯に浸りにくくなり、使用者にとっては不満が生じるものとなってしまう。
また、洗い場部を浴槽に対して高くすることでまたぎ高さを低くすると、スラブ面と防水パンの下面との幅が大きなものになってしまい、その分、洗い場部よりも上の生活空間が上下方向に幅狭になる、という問題が生じる。
そこで、実際に用いられるまたぎ高さを低くする方法として、浴槽と防水パンの間をできるだけ狭くし、その分またぎ高さを低くする方法が主に採用されている。
この方法であれば、浴槽を浅くすることなく、またスラブ面と防水パンの下面との幅を大きくすることなく、またぎ高さを低くすることができる。
【０００７】
しかし、上記のような浴槽と防水パンの間をできるだけ狭くする方法は、排水栓を固定するナット等の部材の厚み分、浴槽載置面との間が必要とされ、充分に跨ぎ高さを低くすることができなかった。
【０００８】
また、上記した、図６に示した遠隔操作式排水栓装置を備えた浴室配管に利用する場合、レリースワイヤなどの操作伝達部材や、それらを排水配管内に挿通させる際に、水密性を確保するためのパッキンなどを配置する高さ幅が、浴槽と浴槽載置面との間に要求されるため、遠隔操作式排水栓装置を備えない浴室配管ほどまたぎ高さを狭くすることができない。
また、図７に示した遠隔操作式排水栓装置を備えた浴室配管の場合は、またぎ高さを、排水栓に遠隔操作式排水栓装置を備えない浴室配管と同等とすることができるが、図６の遠隔操作式排水栓装置を採用した配管構造と比べて、操作伝達部材の挿通ルートを配管する分だけ部材点数や施工の手間が増えるためコストアップし、さらに部材同士の継ぎ目から漏水の可能性が生じる等の問題があった。
【０００９】
本発明は上記問題点に鑑み考案されたものであって、
遠隔操作式排水栓装置を採用した浴室配管において、またぎ高さを可能な限り低いものとしつつ、且つ部材の点数を特に増やさない浴室配管を達成することができる、カバー部材に関するものである。

【００１７】
【発明の実施の形態】
以下に本発明の第一実施例を、図面を参照しつつ説明する。
図１乃至図２に示した本発明のカバー部材（３）は、平面視略円形の板状の部材であって、円形形状の中心部分に、後述する排水栓（５）を接続する、円筒形状にして内周面に雌ねじを設けた固定部（４）を設けてなり、その周囲に円環状に溝部（６）を設けてなる。
また、上記固定部（４）の下端はそのまま排水口（２）内部に解放されており、従って固定部（４）は排水栓（５）の排水を、排水口（２）を介して後述する排水エルボ（１５）内に流入する、流入口としての機能も備えている。
該溝部（６）の底面（６ａ）には、後述するレリースワイヤ（１２）を挿通するための挿通部として挿通孔（１３）が、底面（６ａ）に対して４５度程度の角度を備えて設けられており、更に同じく底面（６ａ）に、シリコンゴムなどの、柔軟で比重が１よりも軽い素材を使ったフロート弁（７ａ）を利用した、上面側から下面側への排水は通すが、下面側から上面側への排水は通さない逆流防止弁（７）が設けられている。この逆流防止弁（７）の通水口（７ｂ）の上端は、底面（６ａ）と同じ高さであって、従って溝部（６）内に流入した排水を完全に排水することができる。
更に、カバー部材（３）の下面に、環状パッキン（１１）が、環の内部に固定部（４）と溝部（６）が配置されるように備えられてなる。
【００１８】
上記したカバー部材（３）は、以下のような浴室配管に用いられる。
本発明のカバー部材（３）を採用した浴室配管は、下記の防水パン（１）、浴槽（Ｂ）、排水トラップ（１４）、排水エルボ（１５）、排水栓（５）、及び遠隔操作式排水栓装置その他の部材から構成される。
防水パン（１）は、浴槽（Ｂ）を載置し、排水が流れる浴槽載置面（１ｂ）を備えた載置部（１ａ）と、載置部（１ａ）に載置される浴槽（Ｂ）の底面より高い位置に、浴室の使用者が身体を洗う等して、使用済みの排水が流れる洗い場面（１ｄ）が設けられた洗い場部（１ｃ）と、両者を隔てる堤防部（１ｅ）とを設けてなり、更に浴槽載置面（１ｂ）と洗い場面（１ｃ）のそれぞれに１／５０〜１／１４０程度の勾配をつけ、その勾配の最下端となる位置に、後述する排水トラップ（１４）または排水エルボ（１５）を取り付けるための取着孔を設けてなる。
浴槽（Ｂ）は、上方が開口した略箱体形状の部材であって、その底面に排水栓（５）を取り付ける排水栓取付孔を備え、また開口の周縁部分に、操作部（１８）を取り付ける操作部取付孔をそれぞれ設けてなる。
排水トラップ（１４）は、内部に封水部（９）と呼ばれる排水の溜まり部分を排水の通路に設けた排水装置であって、上面に設けた、防水パン（１）上の排水を流入する第二排水口（８）、封水部（９）と連通した、接続先の排水が流入する枝管部（１４ａ）、第二排水口（８）、枝管部（１４ａ）からの排水を、封水部（９）を介した上で排出する排出口（１４ｂ）、からなり、該封水部（９）によって、下水側からの臭気や害虫類の逆流を防止している。
排水エルボ（１５）は、防水パン（１）上の排水を流入する、段部（２ａ）を備えた排水口（２）、及び枝管部（１４ａ）に接続され、排水口（２）からの排水を排出する吐出口（１６）からなる排水装置である。なお、該段部（２ａ）の外周縁はカバー部材（３）の外周縁よりも多少大径で、段部（２ａ）の内周縁はカバー部材（３）の環状パッキン（１１）の外周縁よりも多少小径に形成されている。
排水栓（５）は浴槽（Ｂ）の排水栓取付孔に取り付けられる、内部に浴槽排水口（５ａ）を形成した円筒形状の部材であって、排水栓（５）上端には外側面方向に突出したフランジ部（５ｂ）を、円筒部分の外側面にはカバー部材（３）の固定部（４）の雌ねじと螺合する雄ねじを、円筒形状の内部には後述する遠隔操作式排水栓装置の弁体（１７）とレリースワイヤ（１２）を接続する軸受部（５ｃ）を備えてなる。
遠隔操作式排水栓装置は、操作部取付孔に取り付けられ、排水栓（５）の浴槽排水口（５ａ）の開閉を操作する操作部（１８）と、上下に昇降して浴槽排水口（５ａ）の開閉を行う、軸受部（５ｃ）に配置される弁体（１７）と、操作部（１８）に加えられた操作を弁体（１７）に伝達して弁体（１７）を昇降させる、操作伝達部材としてのレリースワイヤ（１２）と、レリースワイヤ（１２）の周囲に配置されるチューブ状の部材であって、レリースワイヤ（１２）と挿通孔（１３）との水密性を確保するためのブッシュパッキン（１９）と、からなる。
【００１９】
上記のように構成した、カバー部材（３）を採用した浴室配管の各部材は、以下のようにして浴室用の防水パン（１）に施工される。なお、必要のある箇所以外は特に記載していないが、各接続箇所／または取付箇所等は、接着もしくはパッキンなどの水密部材を利用した方法によって、漏水等が生じないように水密的に接続／または取付等を行っている。
【００２０】
まず、防水パン（１）に排水トラップ（１４）、排水エルボ（１５）などの排水装置を取り付ける。
排水トラップ（１４）の枝管部（１４ａ）に排水エルボ（１５）の吐出口（１６）を接続した上で、載置部（１ａ）側の取着口には排水エルボ（１５）を、洗い場部（１ｃ）側の取着口には排水トラップ（１４）を、防水パン（１）上の排水がそれぞれの排水口（２、８）に流れ込むように取り付ける。更に排水トラップ（１４）の排出口（１４ｂ）に、下水側へ連通する下水配管を接続する。
なお、この時、排水エルボ（１５）は排水トラップ（１４）の封水部（９）に接続されているため、枝管部（１４ａ）又は吐出口（１６）の上端最下部と、排水トラップ（１４）の封水部（９）の上縁とで封水を形成して、トラップ機能を備える。
【００２１】
次に浴槽（Ｂ）にカバー部材（３）と遠隔操作式排水栓装置を取り付ける。
浴槽（Ｂ）の排水栓取付孔に、排水栓（５）を挿通した上で、排水栓（５）の雄ねじにカバー部材（３）の固定部（４）の雌ねじを螺合させ取付作業を行う。この際は、カバー部材（３）の挿通孔（１３）の位置が、後述するレリースワイヤ（１２）の挿通に適切となる方向にカバー部材（３）を向けた上で、排水栓（５）を回転させて螺合させ、カバー部材（３）の固定部（４）周縁と、排水栓（５）のフランジ部（５ｂ）とで、排水栓取付孔の周縁を挟持するようにして取付固定を行う。
次いで、浴槽（Ｂ）の操作部取付孔に操作部（１８）を取り付けた後、挿通孔（１３）の周縁にブッシュパッキン（１９）が配置され挿通孔（１３）の水密性が確保された状態として、操作部（１８）に接続したレリースワイヤ（１２）をカバー部材（３）の挿通孔（１３）に挿通する。更にレリースワイヤ（１２）の先端を排水栓（５）の軸受部（５ｃ）に接続して、弁体（１７）の昇降が可能となるようにレリースワイヤ（１２）を取り付け、浴槽（Ｂ）への遠隔操作式排水栓装置の取り付けが完了する。
【００２２】
最後に、浴槽（Ｂ）を防水パン（１）の浴槽載置面（１ｂ）上に載置する。この際、カバー部材（３）の環状パッキン（１１）が、排水口（２）の段部（２ａ）に当接するように位置合わせを行いつつ載置する。環状パッキン（１１）は、排水口（２）の段部（２ａ）内周縁よりも若干大径に形成されているため、防水パン（１）と浴槽（Ｂ）との間に、多少水平方向の位置ずれが生じていても、その位置ずれを吸収して、水密的に施工することができる。
【００２３】
この施工が完了した状態において、洗い場面（１ｄ）は、浴槽（Ｂ）の底面ならびに浴槽排水口（５ａ）上縁よりも高い高さ位置である。また、該浴槽排水口（５ａ）より下方の、浴槽載置面（１ｂ）の勾配の最下端よりも低く、且つ略同一の高さに、カバー部材（３）の固定部（４）上縁とカバー部材（３）周縁とが配置されている。
更にそれらより下方の高さ位置に排水トラップ（１４）の封水部（９）の上縁が配置され、この固定部（４）上縁（もしくはカバー部材（３）周縁）と封水部（９）上縁の間となる高さ位置に、カバー部材（３）の挿通孔（１３）と通水口（７ｂ）が備えられている。
なお、上記した「略同一の高さ」とは、施工現場で生じた若干の高さ位置のずれや、部材の成型による厚み誤差、または水密性を確保するために用いられるパッキンの弾性等によって、同一の高さに設計しているものに対し、高さ方向に微細な寸法ずれ（通常は数ミリ程）が生じても、それらの誤差を許容して「同一の高さ」とするものである。また、上記文章中の「浴槽載置面（１ｂ）の勾配の最下端よりも低く、且つ略同一の高さ」とは、高さ方向の微細な寸法ずれを考慮し、その分のマージンを確保して確実に浴槽載置面（１ｂ）の勾配の最下端よりも低くすると共に、なるべく同一の高さに近づける、という考えを示すものである。
【００２４】
上記のように構成された浴室配管において操作部（１８）に操作を加えると、操作伝達部材であるレリースワイヤ（１２）を介して操作部（１８）に加えられた操作が伝達され、弁体（１７）が上昇／下降して浴槽排水口（５ａ）の開閉が行われる。
また、浴槽排水口（５ａ）から排水が行われた場合、浴槽排水口（５ａ）から排水エルボ（１５）を介して、排水トラップ（１４）内に排水が行われ、最終的には封水部（９）を通過して吐出口（１６）から下水側に排水が行われる。
また、浴槽載置面（１ｂ）上に排水があった場合、排水は勾配に沿って排水口（２）に流れ、カバー部材（３）の逆流防止弁（７）の通水口（７ｂ）から排水エルボ（１５）内に排水が流入し、その後は浴槽排水口（５ａ）からの排水と同様に、排水エルボ（１５）を介して、排水トラップ（１４）内に排水が行われ、最終的には封水部（９）を通過して排出口（１４ｂ）から下水側に排水が行われる。
また、洗い場面（１ｄ）上に排水があった場合、排水は勾配に沿って第二排水口（８）に流れ、封水部（９）を通過して排出口（１４ｂ）から下水側に排出される。
【００２５】
上記のような浴室配管において、洗い場面（１ｄ）に大量の排水が生じ、排出口（１４ｂ）からの排水の処理が追いつかなくなった場合、第二排水口（８）からの排水の一部は枝管部（１４ａ）を介し、排水エルボ（１５）内に逆流を生じる場合がある。
この場合、逆流防止弁（７）のフロート弁（７ａ）が働き、通水口（７ｂ）を閉口するため、浴槽載置面（１ｂ）上に排水が逆流して溢れることがない。
【００２６】
上記記載の、本発明のカバー部材（３）を採用した浴室配管においては、レリースワイヤ（１２）の挿通孔（１３）をカバー部材（３）の溝部（６）内に設けているため、図６に示した従来例のように、浴槽（Ｂ）とカバー部材（３）の間に、レリースワイヤ（１２）など操作伝達部材を挿通する幅をとる必要がなく、その分またぎ高さを低くすることができる。
また、図７に示した従来例のように、操作伝達部材を挿通するために特別な配管部材を配置する必要がなく、漏水の危険やコストアップがほとんど生じない。
また、溝部（６）内にレリースワイヤ（１２）等操作伝達部材の挿通部を備えているため、溝部（６）の深さを設計時に調整して、挿通部の水密性を保つ部材（ブッシュパッキン（１９）など）が溝部（６）内に収納されるようにすることで、その分浴槽（Ｂ）下面とカバー部材（３）上面（及び略同一である浴槽載置面（１ｂ））との間を狭くし、またぎ高さを狭くすることができる。上記第一実施例では、図６の従来例と比較して、ブッシュパッキン（１９）の肉厚分だけ高さ幅を狭くなされている。
また、溝部（６）内で操作伝達部材の方向を変更し、カバー部材（３）の上面上において、操作伝達部材を、最もその高さ幅が狭くなる方向に向けることができる。上記第一実施例では、一旦４５度程度にレリースワイヤ（１２）が延出され、それから水平方向にレリースワイヤ（１２）が向かうため、仮にカバー部材（３）の上面上に挿通孔（１３）があれば、４５度程度に延出されてから、水平方向に向かうまでの高さ幅が必要になるところ、溝部（６）内で既に４５度程度にレリースワイヤ（１２）が延出され、更に方向を変えてほぼ水平方向にレリースワイヤ（１２）が延出されているため、カバー部材（３）の上面上ではレリースワイヤ（１２）の高さ幅が最も狭くなる水平方向にそのまま延出することができる。
この効果は、レリースワイヤ（１２）等の操作伝達部材が、カバー部材（３）の上方を向いて延出されていることから（挿通孔（１３）が多少傾斜を備えていたとしても、カバー部材（３）が略水平に形成されている限り、他の効果を損なうことなく上方に向かう要素が無くなることはあり得ない）、操作伝達部材の曲がり半径確保のため、浴槽（Ｂ）下面と防水パン（１）の浴槽載置面（１ｂ）との間には充分な高さ幅が必要となるところ、またぎ高さを低くしたことで、浴槽（Ｂ）下面と浴槽載置面（１ｂ）との間に操作伝達部材の曲がり半径確保のための充分な高さ幅を確保できない場合に、特に有用である。
【００２７】
次に、本願発明の第二実施例を、図面を参照しつつ説明する。
図３乃至図４に示した本発明のカバー部材（３）は、平面視略円形の板状の部材であって、円形形状の中心部分に、後述する排水栓（５）を接続する、円筒形状にして内周面に雌ねじを設けた固定部（４）を設けてなり、その周囲に円環状に溝部（６）を設けてなる。
該溝部（６）の底面（６ａ）には、後述するレリースワイヤ（１２）を挿通するための挿通部として挿通孔（１３）が、底面（６ａ）に対して４５度程度の角度を備えて設けられており、更に同じく底面（６ａ）に、シリコンゴムなどの、柔軟で比重が１よりも軽い素材を使ったフロート弁（７ａ）を利用した、上面側から下面側への排水は通すが、下面側から上面側への排水は通さない逆流防止弁（７）が設けられている。この逆流防止弁（７）の通水口（７ｂ）の上端は、底面（６ａ）と同じ高さであって、従って溝部（６）内に流入した排水を完全に排水することができる。
更に、カバー部材（３）の下面に、環状パッキン（１１）が、環の内部に固定部（４）と溝部（６）が配置されるように備えられてなる。
更に上記のカバー部材（３）においては、カバー部材（３）の下方に該排水栓（５）と同心であって、下方が開口した略逆円錐形状の壁部からなる下カバー部（１０）を設け、該下カバー部（１０）内に、遠隔操作式排水栓装置の操作伝達部材であるレリースワイヤ（１２）を挿通するように構成してなる。
【００２８】
上記したカバー部材（３）は、上記段落００１８に記載された浴室配管の各部材と同様の部材から構成されてなる。
【００２９】
上記のように構成した、カバー部材（３）を採用した浴室配管の各部材は、上記段落００２０乃至段落００２２と同様の方法によって、段落００２３に記載した位置関係となるようにして、浴室用の防水パン（１）に施工される。
【００３０】
また上記のように構成した、カバー部材（３）を採用した浴室配管の各部材は、段落００２４に記載した方法によって使用することができる。
【００３１】
また上記のように構成した、カバー部材（３）を採用した浴室配管の各部材は、段落００２５乃至段落００２６に記載した効果に加えて、レリースワイヤ（１２）など、操作伝達部材を下カバー部（１０）内に配置することで、浴槽（Ｂ）を防水パン（１）上に載置する際、操作伝達部材が浴槽と防水パン（１）との間に挟まれて破損する、という問題を防ぎ、また同時に、その形状的な効果によって、枝管部（１４ａ）等を介し、勢い良く排水が排水エルボ（１５）内に逆流してきた場合に、下カバー部（１０）の壁面が排水の勢いを減じ、浴槽（Ｂ）内等へ逆流が溢れることを防止する、という効果を備えてなる。
【００３２】
本発明の実施例は上記の様であるが、本発明は、上記実施例に限定されるものではなく、発明の要旨を変更しない範囲で自在に変更が可能である。

[Problems to be solved by the invention]
If the above-mentioned straddle height is high, the wall surface that must be overcome becomes high, so that it is difficult for the user to use the bathtub. For this reason, it has become an important subject of bathroom piping in recent years to make this straddle height as low as possible.
However, if the straddle height is lowered by making the bathtub shallow, the amount of bath water is small, and it becomes difficult for the user of the bathtub to immerse the whole body in the bath water, resulting in dissatisfaction for the user.
Also, if the height of the washing area is made higher with respect to the bathtub, the width between the slab surface and the bottom surface of the waterproof pan becomes larger, and the living space above the washing area is increased accordingly. There arises a problem of narrowing in the vertical direction.
Therefore, as a method of reducing the straddle height actually used, a method of narrowing the space between the bathtub and the waterproof pan as much as possible and lowering the straddle height is mainly employed.
With this method, the straddle height can be lowered without making the bathtub shallow and without increasing the width between the slab surface and the bottom surface of the waterproof pan.
[0007]
However, the method for narrowing the gap between the bathtub and the waterproof pan as much as possible requires a space between the bathtub mounting surface and the thickness of a member such as a nut for fixing the drain plug. Could not be lowered.
[0008]
Moreover, when using for the above-mentioned bathroom piping provided with the remote-operated drain plug device shown in FIG. 6, when the operation transmitting member such as a release wire or the like is inserted into the drain piping, water tightness is secured. Since the height width which arrange | positions the packing etc. for doing is requested | required between a bathtub and a bathtub mounting surface, a bathroom piping which does not have a remote control type drain plug apparatus cannot straddle and narrow the height.
In addition, in the case of a bathroom pipe equipped with a remote-operated drain plug device shown in FIG. 7, the straddle height can be equivalent to a bathroom pipe that does not have a remote-operated drain plug device on the drain plug, Compared to the piping structure employing the remote-operated drain plug device of FIG. 6, the number of members and the labor required for construction increase by the amount of piping for the operation transmission member insertion route. There were problems such as the possibility.
[0009]
The present invention has been devised in view of the above problems,
The present invention relates to a cover member that can achieve bathroom piping that does not particularly increase the number of members while keeping the straddle height as low as possible in bathroom piping that employs a remote-operated drain plug device.

The release wire (12) as the operation transmission member and a tubular member disposed around the release wire (12), which secures water tightness between the release wire (12) and the insertion hole (13). And a bush packing (19).
[0019]
Each member of the bathroom piping which employ | adopted the cover member (3) comprised as mentioned above is constructed to the waterproofing pan (1) for bathrooms as follows. In addition, although there is no particular description other than necessary portions, each connection location / or attachment location, etc. is connected in a watertight manner to prevent leakage or the like by a method using a watertight member such as adhesion or packing. Or it is installed.
[0020]
First, drainage devices such as a drain trap (14) and a drain elbow (15) are attached to the waterproof pan (1).
After connecting the discharge port (16) of the drainage elbow (15) to the branch pipe part (14a) of the drainage trap (14), the drainage elbow (15) is attached to the mounting port on the mounting portion (1a) side. A drain trap (14) is attached to the attachment port on the washing area (1c) side so that the drainage on the waterproof pan (1) flows into the drainage ports (2, 8). Further, a sewage pipe communicating with the sewage side is connected to the discharge port (14b) of the drain trap (14).
At this time, since the drainage elbow (15) is connected to the sealing part (9) of the drainage trap (14), the lowermost upper end of the branch pipe part (14a) or the discharge port (16) and the drainage trap A sealing water is formed with the upper edge of the sealing part (9) of (14), and a trap function is provided.
[0021]
Next, a cover member (3) and a remote-operated drain plug device are attached to the bathtub (B).
Insert the drain plug (5) into the drain plug mounting hole of the bathtub (B), and screw the female screw of the fixing part (4) of the cover member (3) into the male screw of the drain plug (5). Do. At this time, the drain plug (5) is positioned after the cover member (3) is directed in a direction in which the insertion hole (13) of the cover member (3) is suitable for insertion of a release wire (12) described later. Rotating and screwing together, fixing the cover member (3) so that the periphery of the drain plug mounting hole is sandwiched between the periphery of the fixing portion (4) of the cover member (3) and the flange portion (5b) of the drain plug (5) I do.
Next, after attaching the operation part (18) to the operation part attachment hole of the bathtub (B), the bush packing (19) is arranged on the periphery of the insertion hole (13), and the water tightness of the insertion hole (13) is ensured. As a state, the release wire (12) connected to the operation part (18) is inserted into the insertion hole (13) of the cover member (3). Further, the tip of the release wire (12) is connected to the bearing portion (5c) of the drain plug (5), the release wire (12) is attached so that the valve body (17) can be raised and lowered, and the bathtub (B) Installation of the remote-operated drain plug device is completed.
[0022]
Finally, the bathtub (B) is placed on the bathtub placement surface (1b) of the waterproof pan (1). At this time, the annular packing (11) of the cover member (3) is placed while being aligned so as to come into contact with the step (2a) of the drain port (2). Since the annular packing (11) has a slightly larger diameter than the inner peripheral edge of the step (2a) of the drain port (2), the annular packing (11) is slightly horizontal between the waterproof pan (1) and the bathtub (B). Even if the positional deviation is generated, it is possible to absorb the positional deviation and perform watertight construction.
[0023]
In the state where this construction is completed, the washing scene (1d) is at a height position higher than the bottom surface of the bathtub (B) and the upper edge of the bathtub drain (5a). Further, the upper edge of the fixing portion (4) of the cover member (3) is lower than the lowest end of the gradient of the bathtub mounting surface (1b) below the bathtub drainage port (5a) and substantially the same height. And the periphery of the cover member (3).
Furthermore, the upper edge of the sealing part (9) of the drain trap (14) is arranged at a height position below them, and the fixing part (4) upper edge (or the periphery of the cover member (3)) and the sealing part ( 9) An insertion hole (13) and a water passage (7b) of the cover member (3) are provided at a height position between the upper edges.
The above "substantially the same height" means a slight shift in the height position generated at the construction site, a thickness error due to molding of the member, or elasticity of the packing used to ensure water tightness. Even if a minute dimensional deviation (usually about several millimeters) occurs in the height direction compared to the one designed at the same height, these errors are allowed to be "the same height" It is. Further, in the above sentence, “the height which is lower than the lowermost end of the gradient of the bathtub mounting surface (1b) and is substantially the same” means that a margin of that amount is taken into account in consideration of minute dimensional deviation in the height direction. The idea of ensuring and making it lower than the lowest end of the gradient of the bathtub mounting surface (1b) and as close to the same height as possible is shown.
[0024]
When an operation is applied to the operation unit (18) in the bathroom pipe configured as described above, the operation applied to the operation unit (18) is transmitted via the release wire (12) which is an operation transmission member. (17) rises / falls to open / close the bathtub drain (5a).
Moreover, when drainage is performed from the bathtub drain outlet (5a), drainage is performed in the drain trap (14) through the drain elbow (15) from the bathtub drain outlet (5a), and finally the sealed water Water is discharged from the discharge port (16) to the sewage side through the section (9).
Moreover, when there is drainage on the bathtub mounting surface (1b), the drainage flows along the gradient to the drainage port (2) and from the water flow port (7b) of the backflow prevention valve (7) of the cover member (3). Drainage flows into the drainage elbow (15) and then drains into the drainage trap (14) via the drainage elbow (15) in the same manner as the drainage from the bathtub drainage port (5a). In this case, the water is discharged from the discharge port (14b) to the sewage side through the sealed portion (9).
In addition, when there is drainage on the washing scene (1d), the drainage flows along the gradient to the second drainage port (8), passes through the sealing portion (9), and goes from the discharge port (14b) to the sewage side. Discharged.
[0025]
In the bathroom piping as described above, when a large amount of drainage occurs in the washing scene (1d) and the wastewater treatment from the discharge port (14b) cannot catch up, a part of the drainage from the second drainage port (8) A backflow may occur in the drainage elbow (15) through the branch pipe (14a).
In this case, since the float valve (7a) of the backflow prevention valve (7) works and closes the water flow opening (7b), the drainage does not flow back and overflow on the bathtub mounting surface (1b).
[0026]
In the bathroom pipe adopting the cover member (3) of the present invention described above, the insertion hole (13) of the release wire (12) is provided in the groove (6) of the cover member (3). As in the conventional example shown in FIG. 6, it is not necessary to provide a width for inserting an operation transmitting member such as a release wire (12) between the bathtub (B) and the cover member (3), and the height of the straddling is reduced accordingly. can do.
Further, unlike the conventional example shown in FIG. 7, it is not necessary to arrange a special piping member for inserting the operation transmitting member, and there is almost no risk of water leakage and an increase in cost.
Further, since the insertion portion of the operation transmission member such as the release wire (12) is provided in the groove portion (6), the member (bush that maintains the water tightness of the insertion portion by adjusting the depth of the groove portion (6) at the time of design. By allowing the packing (19) and the like to be accommodated in the groove (6), the lower surface of the bathtub (B) and the upper surface of the cover member (3) (and the substantially identical bathtub mounting surface (1b)) It is possible to narrow the gap between and the height of the straddle. In the first embodiment, the height width is narrowed by the thickness of the bush packing (19) as compared with the conventional example of FIG.
In addition, the direction of the operation transmission member can be changed in the groove (6), and the operation transmission member can be directed in the direction in which the height width becomes narrowest on the upper surface of the cover member (3). In the first embodiment, since the release wire (12) is once extended to about 45 degrees and then the release wire (12) is directed in the horizontal direction, the insertion hole (13) is temporarily provided on the upper surface of the cover member (3). If there is, a height width is required from about 45 degrees to the horizontal direction, the release wire (12) is already extended to about 45 degrees in the groove (6), Further, since the release wire (12) extends in a substantially horizontal direction by changing the direction, the release wire (12) extends in the horizontal direction where the height width of the release wire (12) is the narrowest on the upper surface of the cover member (3). can do.
This effect is because the operation transmitting member such as the release wire (12) extends upward from the cover member (3) (even if the insertion hole (13) has a slight inclination) As long as the member (3) is formed substantially horizontally, there is no possibility that the element going upward without impairing other effects), in order to secure the bending radius of the operation transmitting member, Where a sufficient height is required between the waterproof pan (1) and the bathtub mounting surface (1b), the lower height of the straddle makes the bathtub (B) lower surface and the bathtub mounting surface (1b). ) Is particularly useful when a sufficient height width for securing the bending radius of the operation transmitting member cannot be secured.
[0027]
Next, a second embodiment of the present invention will be described with reference to the drawings.
The cover member (3) of the present invention shown in FIGS. 3 to 4 is a plate-like member having a substantially circular shape in plan view, and is a cylinder that connects a drain plug (5) to be described later to a central portion of the circular shape. A fixed portion (4) having a shape and an internal thread is provided on the inner peripheral surface, and an annular groove (6) is provided around the fixed portion.
The bottom surface (6a) of the groove portion (6) has an insertion hole (13) as an insertion portion for inserting a release wire (12), which will be described later, with an angle of about 45 degrees with respect to the bottom surface (6a). Furthermore, drainage from the upper surface side to the lower surface side through the bottom surface (6a) using a float valve (7a) made of a flexible material having a specific gravity less than 1 such as silicon rubber is allowed to pass. A backflow prevention valve (7) that does not allow drainage from the lower surface side to the upper surface side is provided. The upper end of the water flow opening (7b) of the backflow prevention valve (7) has the same height as the bottom surface (6a), and therefore, the wastewater flowing into the groove (6) can be completely drained.
Furthermore, an annular packing (11) is provided on the lower surface of the cover member (3) so that a fixing part (4) and a groove part (6) are arranged inside the ring.
Further, in the above cover member (3), the lower cover portion (10) comprising a substantially inverted conical wall portion that is concentric with the drain plug (5) below the cover member (3) and opens downward. And a release wire (12), which is an operation transmission member of the remote-operated drain plug device, is inserted into the lower cover portion (10).
[0028]
The cover member (3) described above has the paragraph 001 described above. 8 It is comprised from the member similar to each member of the bathroom piping described in 1).
[0029]
Each member of bathroom piping which employ | adopted the cover member (3) comprised as mentioned above is the said paragraph 00. 20 To paragraph 002 2 In the same way as in paragraph 002 3 It is applied to the waterproofing pan (1) for bathrooms so that it may become the positional relationship described in (1).
[0030]
Moreover, each member of bathroom piping which employ | adopted the cover member (3) comprised as mentioned above is paragraph 002. 4 Can be used.
[0031]
Moreover, each member of bathroom piping which employ | adopted the cover member (3) comprised as mentioned above is paragraph 002. 5 To paragraph 002 6 In addition to the effects described above, an operation transmitting member such as a release wire (12) is disposed in the lower cover part (10), so that the operation can be performed when the bathtub (B) is placed on the waterproof pan (1). The problem that the transmission member is sandwiched between the bathtub and the waterproof pan (1) and is damaged is prevented, and at the same time, the drainage is drained vigorously through the branch pipe portion (14a) or the like due to its shape effect. When it flows back into the elbow (15), the wall surface of the lower cover part (10) reduces the momentum of the drainage and prevents the backflow from overflowing into the bathtub (B) or the like.
[0032]
The embodiments of the present invention are as described above. However, the present invention is not limited to the above embodiments, and can be freely changed without departing from the scope of the invention.
For example, in each of the above embodiments, any bathroom pipe employs a remote-operated drain plug device, but even if the remote control drain tap device is not provided, the nut member is omitted, The height can be lowered.
[0033]
In each of the above embodiments, in any bathroom pipe, the inflow port into which the drainage flows into the cover member (3) is configured as an integral part with the fixing portion (4) for connecting and fixing the drain plug (5). However, when the remote-operated drain plug device having the insertion portion at the stepped portion (6) is adopted for the bathroom pipe, the drain plug (5) is fixed by the fixing portion (4) made of a nut member or the like, Paragraph 002 may also be adopted as a structure in which drainage flows from an inlet separate from the fixing portion (4) provided on the cover member (3). 6 From the effect described in (1), the straddle height can be made lower than that of the cover member (3) not provided with the groove (6).

Moreover, in each said Example, the insertion hole (13) which is an insertion part, and the water flow hole (7b) of a backflow prevention valve (7) are provided on the bottom face (6a) of a flat groove part (6). However, if the bottom surface (6a) of the groove portion (6) is inclined and the water passage hole (7b) is located at the lowermost position of the groove portion (6), a small amount of drainage is accumulated in the groove portion (6). This also eliminates this and makes the cover member (3) more hygienic.
