Description

【０００１】
【発明の属する技術分野】
本発明は、浴槽や洗面台などの槽体の底面に開口された排水口を開閉するための栓蓋部材と、該栓蓋部材を用いた排水装置に関するものである。
【０００２】
【従来の技術】
従来より、浴槽や洗面台など、使用によって排水を生じる槽体には、生じた排水を処理するため、排水装置が用いられている。図１６に示したのはその一例で、これら排水装置には、通常、排水を下水側に排出するため槽体の底面に排水口を開口すると共に、必要に応じて排水口を閉口するための弁部材や、排水の下流側に毛髪や微少なゴミ等が流れ込むことを防止する目皿部材が備えられている。
【０００３】
清掃などの際に、これら排水装置に用いられる弁部材また目皿部材を別々に取り出すことは手間であるから、洗面台の排水装置などでは両者を組み合わせて一体の栓蓋部材として利用する方法が近年多くなってきている。しかしながら、この場合は弁部材と目皿部材を着脱不可能に組み合わせて一つの部材としたため、清掃の際に手を入れることができない狭隘な部分や方向などが発生し、清掃性は悪化することとなっていた。
【０００４】
かかる問題の解決のため、本出願人は、特願平９−２７０３１４号（特開平１１−６１９３１号）において、弁部材と目皿部材の着脱を可能とした栓蓋部材を発明している。その具体的な構成としては、
１．弁体の下面中央部に突起部材を突設し、該突起部材と前記弁体を支持する軸部との間隙に弾性部材を配設して、弁体と軸部を着脱自在とし、この着脱箇所から目皿部材を取り出す方法、
２．弁体と軸部を一体に構成すると共に、軸部の外周面に凹溝を周設し、この凹溝にストッパーの役割を果たす弾性部材を嵌入することで、目皿部材の抜き差しを自在とする方法、
３．軸部にガイド面等を周設し、また目皿部材の一部を切欠して、ガイド面と切欠部分を合わせることで目皿部材を側面方向から引き抜く方法、
４．軸部に横方向の貫穿孔を形設し、この貫穿孔に掛止突子を軸着して、この掛止突子の方向を軸部の方向に合わせることで、目皿部材を取り出す方法、
等が示されている。
【０００５】
【発明が解決しようとする課題】
しかしながら、上記のような栓蓋部材は、次に記載したような問題点を有しており、実使用には不適であった。
ａ．上記１．の場合、弁体と軸部、目皿部材がそれぞれ別部材にて構成されているため、分解／組立に手間が掛かり面倒である。また使用により弾性部材が劣化して弁体と軸部の係合力が弱くなると、排水口内に軸部と目皿部材が落下して利用不可能となる場合がある。
ｂ．上記２．の場合、弁部材と目皿部材、弾性部材がそれぞれ別部材にて構成されているため、分解／組立に手間が掛かり面倒である。また弾性部材が劣化して弁部材と弾性部材の係合力が弱くなると、排水口内に弾性部材と目皿部材が落下して利用不可能となる場合がある。
ｃ．上記３．の場合、目皿部材の切欠部分は強度的に弱く、壊れやすい。また切欠分だけ目皿の孔が広く開口しているため、その部分から排水中の毛髪・ゴミなどが流れ出し易い。
ｄ．上記４．の場合、軸部に横方向の貫穿孔を形設しているため、強度的に通常の軸部よりも弱いものとなってしまう。また、この貫穿孔に掛止突子を軸着するなど細かい機構が要求されるため必然的に構造は複雑となり、故障しやすくまた単価は高くなる。また使用時に偶然係止突子の向きが軸部の向きと一致した場合、排水口内に目皿部材が落下して利用不可能となる場合がある。
【０００６】
また、近年排水装置を含む排水配管においては、配管に求められるスペースの全高を狭めることで、床下空間やキャビネット内のデッドスペースをできる限り狭め、その分生活空間やキャビネット内の収納空間を上下方向に大きく確保することが強く求められている。
この目的の達成の為に、遠隔操作式の排水装置においては、図１７に示したように、弁部材を下面中央に係合口を設けた弁体のみから構成し、この弁体の係合口に、レリースワイヤのロッド部先端に設けた係合部を直接係合させる方法が考案されている。このようにすることで、図１６に示した栓蓋部材を採用した遠隔操作式排水装置に比べて、軸部に必要とされる高さ分（例えば軸部が傾かないように軸受部材の円筒部内に常に収納されている高さ幅など）だけ高さ幅を狭くすることができる。
【０００７】
しかし図１７に示した遠隔操作式排水装置については、弁部材に軸部が存在しないため、段落０００４の１．〜４．に示した各方法を利用することができず、弁部材と目皿部材を別々の部材とする方法しか利用できなかった。
本発明は上記問題点に鑑み発明されたもので、弁部材と目皿部材を着脱自在とした栓蓋部材と、該栓蓋部材の使用に適した排水装置を提供するものである。

【００１４】
【発明の実施の形態】
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３に図示した、本発明の第一実施例による栓蓋部材（１）は、以下に記載した弁部材（３）及び目皿部材（７）から成る。
弁部材（３）は、後述する排水口（２）を閉口する平面視円形状の弁体（４）と、該弁体（４）の中央部下面より下方に垂下された、下端に外周方向に向かって周縁に沿って突出した突部（６）を有する軸部（５）よりなる。
目皿部材（７）は上下に開口した筒状にして該弁部材（３）の軸部（５）を昇降自在に収納する筒部（８）と、筒部（８）外側面から外方向に向かって放射状に設けられた複数のスリット及びスリットの外側端部を円弧状に連結する環状部分から成る目皿部（１０）と、更に筒部（８）の上端に設けた、縦方向の切り欠きによって弾性を備えると共に、内周側に設けた突出部分によって弁部材（３）の突部（６）と係合する係合爪（９）、から構成されてなる。
【００１５】
また、上記栓蓋部材（１）は、図４また図５に示した、以下に記載した、排水口（２）を有する排水栓（２０）、軸受部材（２２）、レリースワイヤ（１９）、等の各部材から構成された排水装置に使用されて成る。
排水栓（２０）は、内部に排水口（２）を形成する略円筒形状であって、その上縁外周側にフランジ部を設け、また排水口（２）内周面に、円弧に沿って複数の凸部（２１）が設けられて成る。
軸受部材（２２）は排水口（２）内に着脱自在に配置・固定される部材であって、弁部材（３）の軸部（５）を収納すると共に、下端に後述するレリースワイヤ（１９）のアウターチューブ（１９ａ）端部を接続する円筒部（２３）と、排水口（２）内の凸部（２１）上に載置した状態で着脱自在に固定配置されるリング部（２４）、該リング部（２４）に設けられた、排水口（２）の凸部（２１）と係合して軸受部材（２２）を固定する爪部（２５）及びリング部（２４）と円筒部（２３）を支持する支持翼（２６）と、から成る。
レリースワイヤ（１９）は、可撓性を備えた中空のアウターチューブ（１９ａ）と、該アウターチューブ（１９ａ）内を軸方向に摺動自在に進退するインナーワイヤ（１９ｂ）と、インナーワイヤ（１９ｂ）の一端に備えられ、アウターチューブ（１９ａ）を軸受部材（２２）の円筒部（２３）下端に接続した際に、上記弁部材（３）の軸部（５）下方に配置され昇降軸（１３）として機能するロッド部、から成る。尚、以後本第一実施例及び第二実施例においてはロッド部は昇降軸（１３）として機能するため昇降軸（１３）と表現する。
またその他の部材として、排水栓（２０）と接続する開口部（２７）、レリースワイヤ（１９）が挿通する挿通孔（２８）、及び排水口（３）からの排水を下水側に排出する為の排出口（２９）を有したエルボ部材（２６）、及びレリースワイヤ（１９）の一端に接続されて、インナーワイヤ（１９ｂ）の進退動作を制御することで排水口（２）の開閉を操作する操作部（１８）とを備えて成る。
【００１６】
上記のように構成した栓蓋部材（１）及びそれを用いた排水装置は、以下のようにして浴槽等の槽体（Ｂ）に設けられた取着孔に取着される。
まず槽体（Ｂ）の底面に設けられた取着孔に排水栓（２０）の円筒部分を挿通し、更にエルボ部材（２６）の開口部（２７）に接続して、取着孔の周縁をフランジ部下面と開口部（２７）上面とで挟持させて排水栓（２０）及びエルボ部材（２６）を取着孔に取着固定する。
次にレリースワイヤ（１９）の一端を操作部（１８）に接続してから、レリースワイヤ（１９）の他端、昇降軸（１３）側をエルボ部材（２６）の挿通孔（２８）を介して排水口（２）内に引き上げる。その後、軸受部材（２２）の円筒部下端にアウターチューブ（１９ａ）の端部を接続した上で、軸受部材（２２）のリング部（２４）を、排水栓（２）の凸部（２１）上面に載置し、また凸部（２１）に爪部（２５）を係合させて軸受部材（２２）を排水口（２）内に固定する。更に、目皿部材（７）の筒部（８）内に弁部材（３）の軸部（５）を挿通させ、栓蓋部材（１）とする。この際、軸部（５）下端の突部（６）が目皿部材（７）の係合爪（９）と衝突するが、係合爪（９）には弾性が備えられているため、その径が拡径して軸部（５）を筒部（８）内に挿通することができる。
該栓蓋部材（１）の弁部材（３）の軸部（５）を円筒部（２３）内に収納し、軸部（５）下端が昇降軸（１３）先端の直上に配置されることで、栓蓋部材（１）と、該栓蓋部材（１）を用いた排水装置の施工が完了する。
【００１７】
上記のように構成した遠隔操作式排水装置を使用する場合、まず操作部（１８）に操作を加えて、栓蓋部材（１）の弁体（４）が排水口（２）を閉口した状態とする。この状態より操作部（１８）に操作を加えて、インナーワイヤ（１９ｂ）を排水栓（２０）側に突出した状態で固定すると、弁軸（５）下端が昇降軸（１３）に押し上げられ、栓蓋部材（１）の弁部材（３）が上昇し、排水口（２）が開口する。
この状態より再度操作部（１８）に操作を加えて、インナーワイヤ（１９ｂ）の固定を解除すると、インナーワイヤ（１９ｂ）が操作部（１８）側に後退して弁体（４）が下降し、排水口（２）が弁部材（３）の弁体（４）により閉口される。以後、同様の操作を繰り返すことで排水口（２）の開口／閉口を自在に操作することができる。
【００１８】
また上記第一実施例の栓蓋部材（１）は、弁部材（３）を持ち上げて引き抜くことで、係合している目皿部材（７）をも同時に取り出すことができる。更に第一実施例の栓蓋部材（１）は、弁部材（３）と目皿部材（７）とが弾性を備えた係合爪（４）によって係合しているため、多少力を加えながら引き抜くことで、弁部材（３）と目皿部材（７）を分離することができ、容易に清掃を行うことができる。また、段落００１６に記載した手順によって、栓蓋部材（１）を組み立て、排水口（２）に装着することも容易に行うこともできる。
【００１９】
次に本発明の第二実施例を、図面を参照しつつ説明する。
図６乃至図８に図示した、本発明の第二実施例による栓蓋部材（１）は、以下に記載した弁部材（３）及び目皿部材（７）から成る。
弁部材（３）は、後述する排水口（２）を閉口する平面視円形状の弁体（４）と、該弁体（４）の下面中央に設けた、弾性を備えた係合口（１１）より成る。
目皿部材（７）は、上端に弁部材（３）の係合口（１１）と係合する係合部（１２）を備えた軸部（５）と、軸部（５）外側面から外方向に向かって放射状に設けられた複数のスリット及び該スリットの外側端部を円弧状に連結する環状部分から成る目皿部（１０）と、更に目皿部材（７）の下面中央に設けた、弁部材（３）の係合口（１１）と略同形状である第二係合口（１５）より成る。
【００２０】
また、上記栓蓋部材（１）は、図９また図１０に示した、以下に記載した、排水口（２）を有する排水栓（２０）、軸受部材（２２）、レリースワイヤ（１９）、等の各部材から構成された排水装置の排水口（２）に使用されて成る。
排水栓（２０）は、内部に排水口（２）を形成する略円筒形状であって、その上縁外周側にフランジ部を設けてなる。
軸受部材（２２）は排水口（２）内に着脱自在に配置・固定される部材であって、中央部分に後述するレリースワイヤ（１９）のアウターチューブ（１９ａ）端部を接続する円筒部（２３）と、排水口（２）内の凸部（２１）上に載置した状態で着脱自在に固定配置されるリング部（２４）、及びリング部（２４）と円筒部（２３）を支持する支持翼（２６）と、から成る。
レリースワイヤ（１９）は、可撓性を備えた中空のアウターチューブ（１９ａ）と、該アウターチューブ（１９ａ）内を軸方向に摺動自在に進退するインナーワイヤ（１９ｂ）と、インナーワイヤ（１９ｂ）の一端に備えられた昇降軸（１３）から成り、更に昇降軸（１３）の先端には上記目皿部材（７）の第二係合口（１５）と係合する、目皿部材（７）の軸部（５）先端の係合部（１２）と略同形状の第二係合部（１４）を設けて成る。但し、この第二係合口（１５）と第二係合部（１４）の係合の強度は、係合口（１２）と係合部またその他の部材として、排水栓（２０）と接続する開口部（２７）、レリースワイヤ（１９）が挿通する挿通孔（２８）、及び排水口（３）からの排水を下水側に排出する為の排出口（２９）を有したエルボ部材（２６）、及びレリースワイヤ（１９）の一端に接続されて、インナーワイヤ（１９ｂ）の進退動作を制御することで排水口（２）の開閉を操作する操作部（１８）とを備えて成る。
【００２１】
上記のように構成した栓蓋部材（１）及びそれを用いた排水装置は、以下のようにして浴槽等の槽体（Ｂ）に設けられた取着孔に取着される。
まず槽体（Ｂ）の底面に設けられた取着孔に排水栓（２０）の円筒部分を挿通し、更にエルボ部材（２６）の開口部（２７）に接続して、取着孔の周縁をフランジ部下面と開口部（２７）上面とで挟持させて排水栓（２０）及びエルボ部材（２６）を取着孔に取着固定する。
次にレリースワイヤ（１９）の一端を操作部（１８）に接続してから、レリースワイヤ（１９）の他端、昇降軸（１３）側をエルボ部材（２６）の挿通孔（２８）を介して排水口（２）内に引き上げる。その後、軸受部材（２２）の円筒部下端にアウターチューブ（１９ａ）の端部を接続した上で、軸受部材（２２）のリング部（２４）を、排水栓（２）の凸部（２１）上面に載置し、また突部（６）に爪部（２５）を係合させて軸受部材（２２）を排水口（２）内に固定する。
次に目皿部材（３）の係合部（１２）を弁部材（３）の係合口（１１）に係合固定した後、該目皿部材（７）の第二係合口（１５）を、昇降軸（１３）の先端の第二係合部（１４）に係合させて、栓蓋部材（１）と、該栓蓋部材（１）を用いた排水装置の施工が完了する。
【００２２】
上記のように構成した遠隔操作式排水装置を使用する場合、まず操作部（１８）に操作を加えて、栓蓋部材（１）の弁体（４）が排水口（２）を閉口した状態とする。この状態より操作部（１８）に操作を加えて、インナーワイヤ（１９ｂ）を排水栓（２０）側に突出した状態で固定すると、昇降軸（１３）の上昇に伴って、昇降軸（１３）と係合している栓蓋部材（１）が押し上げられ、弁体（４）が上昇し、排水口（２）が開口する。
この状態より再度操作部（１８）に操作を加えて、インナーワイヤ（１９ｂ）の固定を解除すると、インナーワイヤ（１９ｂ）が操作部（１８）側に後退して弁体（４）が下降し、排水口（２）が弁部材（３）の弁体（４）により閉口される。以後、同様の操作を繰り返すことで排水口（２）の開口／閉口を自在に操作することができる。
【００２３】
また上記第二実施例の栓蓋部材（１）は、係合部（１２）と係合口（１１）の係合の強度を、第二係合部（１４）と第二係合口（１５）の係合の強度よりも多少強く設定しているため、弁部材（３）を持ち上げることで、係合している目皿部材（７）をも同時に取り出すことができる。更に第二実施例の栓蓋部材（１）は、弁部材（３）と目皿部材（７）とが係合部（１２）によって係合しているため、多少力を加えながら両部材を離間することで弁部材（３）と目皿部材（７）を分離することができ、容易に清掃を行うことができる。また、段落００２１に記載した手順によって、栓蓋部材（１）を組み立て、排水口に装着することも容易に行うこともできる。
【００２４】
本発明の実施例は上記のようであるが、本発明は上記実施例に限定される物ではなく、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。
例えば上記各実施例においては昇降機構を、操作部（１８）とレリースワイヤ（１９）を用いた、遠隔操作式の排水装置としているが、図１１に示した実施例のように、排水口（２）内に、スラストロックと呼ばれる、昇降軸（１３）を有する単純な昇降機構を備えた排水装置に本発明の栓蓋部材（１）を用いても良い。
【００２５】
また、上記各実施例においては、目皿部材（７）を支持翼（１７）の上面に載置することによって目皿部材（７）が排水口（２）内に落下することがないように構成されているが、図１２に示した実施例のように、排水装置に昇降機構を支持する支持翼（１７）がない場合でも、排水口（２）内に突起部（１６）を設けることによって目皿部材（７）の落下を防止するように構成しても良い。
【００２６】
また、栓蓋部材（１）の構成を、図１３乃至図１５に示した実施例のように、第二実施例の栓蓋部材（１）から、第二係合口（１５）を省略したような構成としても良い。このような構成の栓蓋部材（１）でも、本発明の目的である、弁部材と目皿部材とが着脱自在な栓蓋部材、という目的を達成することができる。
【００２７】
本発明は上記のように構成したため、以下のような優れた効果を奏する。
１）請求項１また請求項２に記載の本発明の栓蓋部材においては、栓蓋部材を構成する弁部材と目皿部材の２部材を着脱可能としたため、着脱不可能な従来品よりも清掃性が向上した。更に、栓蓋部材は２部材のみから成るため、着脱可能ではあるが３部材などから成る従来品よりも安価且つ簡潔で、清掃作業も容易に行うことができる。
２）請求項３に記載の本発明の栓蓋部材においては、目皿部材に第二係合口を設け、また軸心部に第二係合部を設けてなる。これによって、本発明の栓蓋部材を、低床使用の排水装置に適応させることができる。また、第二係合口と第二係合部の形状を係合口及び係合部と略同一の形状としたことで、軸心部の長さを目皿部材の軸部の高さ分だけ縮めたレリースワイヤに交換するだけで、従来目皿部材を用いない仕様の低床用排水装置にも本発明の栓蓋部材の構造を採用することができる。
３）請求項４又は請求項５に記載の排水装置によれば、弁部材から目皿部材が脱落するようなことがあっても、排水口内に設けた突起部又は支持翼によって、目皿部材が排水口内に落下することを防止することができる。
４）請求項６に記載の排水装置によれば、本発明の排水装置の昇降機構の昇降動作を、遠隔操作式に操作することができる。

BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a plug lid member for opening and closing a drain opening opened on the bottom surface of a tank body such as a bathtub or a washstand, and a drainage device using the plug lid member.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, drainage devices have been used for tank bodies that generate drainage by use, such as bathtubs and washstands, in order to treat the generated drainage. FIG. 16 shows an example of such a drainage device. Usually, in order to discharge the drainage to the sewage side, a drainage port is opened on the bottom surface of the tank body, and the drainage port is closed if necessary. A valve member and an eye plate member for preventing hair and minute dust from flowing into the downstream side of the drainage are provided.

Etc. are shown.
[0005]
[Problems to be solved by the invention]
However, the plug lid member as described above has the following problems and is not suitable for actual use.
a. Above 1. In this case, since the valve body, the shaft portion, and the eye plate member are configured as separate members, it takes time and effort to disassemble / assemble. Further, when the elastic member deteriorates due to use and the engagement force between the valve body and the shaft portion becomes weak, the shaft portion and the eye plate member may fall into the drainage port and become unusable.
b. 2. In this case, since the valve member, the eye plate member, and the elastic member are configured as separate members, it takes time and effort to disassemble / assemble. Further, when the elastic member deteriorates and the engagement force between the valve member and the elastic member becomes weak, the elastic member and the countersink member may fall into the drain and become unusable.
c. 3. above. In this case, the cutout portion of the eye plate member is weak in strength and easily broken. In addition, since the hole in the eye plate is wide as much as the cutout, hair, dust, etc. in the drainage easily flows out from that portion.
d. 4. above. In this case, since the horizontal through-hole is formed in the shaft portion, the strength is weaker than that of the normal shaft portion. Further, since a fine mechanism such as attaching a latching protrusion to the through hole is required, the structure is inevitably complicated, and it is easy to break down and the unit price is high.
