Description

【０００１】
【産業上の利用分野】
本発明は、既設の止水栓本体を取り除いた後に装着し、分岐路を形成する分岐水栓に関する。更に詳しくは、水道上水を水洗トイレに使用するロータンクに溜めるための給水管に取り付けられた止水栓を取外し、ロータンクへの水と温水洗浄機に使用される水とに分岐するための分岐水洗に関する。
【０００２】
【従来の技術】
図６に特開平６−１３６７９５号公報に記載される従来技術を示す。図６において、１は止水栓本体２に装着された分岐水栓であり、６は止水栓本体２を止水する止水弁である。５は止水弁６を保持し、止水弁６の開閉を司るスピンドルであり、７は分岐路３への流出部１０を止水する水流入口用止水弁である。１１は水流入口用止水弁７を保持し、水流入口用止水弁７の開閉を司る２つめのスピンドルである。なお、９は止水栓本体２からロータンク等（図示せず）に接続される給水管である。
水道上水は、水流入部１２から流水口１４を通り、給水管９より送水されるものと分岐路３より送水されるものとに分岐される。図６から明らかなように、使用者は、自分がどの部分に水を送水するかによって２つのスピンドルを調整し、水の流路を決定することになる。
【０００３】
【発明が解決しようとする課題】
上記の従来技術では、止水栓本体２の止水を司るスピンドル５と分岐路３の止水を司るスピンドル１１とを別々に必要とし、構造的に複雑であるばかりでなく、コスト的にも高いものとなっていた。しかも使用者は、自分の選択する流路を決定するために２つのスピンドル５、１１を別々に調整しなければならない。
本発明は、上記した従来技術の問題点の解決を図ることの出来る、スピンドル１つで流路を決定することの可能な分岐水栓を提供するものである。
【０００４】
【課題を解決するための手段】
本発明は、止水用隔壁１３の下流に２つの水流出口８、８’を備えた止水栓本体２に対して、前記止水用隔壁１３を通過する水の流路軸芯と同一の軸芯を有する水流出口８に設置される分岐水栓であって、分岐路３を有した分岐水栓部材１と、止水弁６と水流入口用止水弁７を有したスピンドル５からなり、前記分岐水栓部材１に止水用隔壁１３に対し前記流路軸芯方向に移動自在となるようスピンドル５を螺着させ、且つ分岐水栓部材１とスピンドル５の間に水流入通路１９を設け、止水栓本体２の流水口１４を止水する止水弁６と前記水流入通路１９上流側の水流入口４を止水する水流入口用止水弁７との間の距離（Ｄ１）が、流水口１４と水流入口４との間の距離（Ｄ２）より短く、前記スピンドル５の移動によって、前記分岐水栓全体の止水と前記分岐路３の止水との切り替えと、前記流水口１４を開放し、前記水流入口４を開放して、前記水流出口８’及び前記分岐路３共に水を流すことができる分岐水栓を提供することを目的とする。
【０００５】
【作用】
本発明は、１つのスピンドルに対し止水用隔壁部分を止水する止水弁及び分岐させるための水流入口部分を止水する水流入口用止水弁の双方を、Ｄ１＜Ｄ２の関係を保つように設けたことによって、２つのスピンドルを用いることなく、１つのスピンドルによって分岐水栓全体の止水と分岐路の止水とを切り替えることが出来る。
【０００６】
【実施例】
次に本発明の実施例を説明する。図５は給水管９を介してロータンク１８に接続された止水栓本体２に分岐水栓を装着する外観を示している。図中にある止水栓本体２を拡大して図４に示すと、止水栓本体２は、図示しない給水元管に接続した水流入部１２、止水用隔壁１３により形成された流水口１４、該流水口１４の下流の水流出口８及びこの水流出口８に連通し、ロータンク等（図示せず）に接続される給水管９を接続する接続口１５を備えている。また、止水弁６を保持するスピンドル５´がキャップ１６により固定されている。
本発明の分岐水栓を装着する場合、先ず水の元栓（図示せず）を締め、止水栓本体２のキャップ１６を取外し、スピンドル５´と止水弁６とを取り出し、止水栓本体２の水流出口８を開口させる。次に止水栓本体２の水流出口８に本発明の分岐水栓を装着する。
【０００７】
図１は本発明の分岐水栓を止水栓本体２に装着した状態を示すものであり、水流入部１２からの水の流入を阻止するための止水弁６と分岐路３への水の流入を阻止するための水流入口用止水弁７を有したスピンドル５が分岐水栓部材１に螺着されている。スピンドル５と分岐水栓部材１の間には、分岐路３へ水を流入させるための水流入通路１９が設けられており、流入口用止水弁７は前記水流入通路１９の上流側にある水流入口４を塞ぎ止水する。この時、止水栓本体２の流水口１４を止水する止水弁６と前記水流入通路１９上流側の水流入口４を止水する水流入口用止水弁７との間の距離（Ｄ１）が、流水口１４と水流入口４との間の距離（Ｄ２）より短くして設けることに注意する。
【０００８】
スピンドル５は、前述したように分岐水栓部材１に螺着されているため、コイン等を使用することによって止水用隔壁に対し前記流路軸芯方向に自由に移動させることができる。そして、この移動状況により本発明の分岐水栓は、３パターンをとりうる。それを以下図１、２、３を用いて説明する。
【０００９】
図１の状態は、スピンドル５を水道上水が流入してくる上流側に移動させている場合である。この時スピンドル５の先端にある止水弁６は、流水口１４を塞ぎ水流入部１２からの水道上水の流入を阻止する。従って分岐水栓には、水道上水が流入することなく、当然給水管９及び分岐路３共に水が流れない。
【００１０】
図２の状態は、スピンドル５を水道上水が流入してくる下流側に移動させている場合である。この時スピンドル５に設けられた水流入口用止水弁７は、水流入通路１９の入口である水流入口４を塞ぎ、同じくスピンドル５に設けられた止水弁６は、流水口１４を開放する。従って、給水管９には水が流れるが、分岐路３には水が流れない。
【００１１】
図３の状態は、図１と図２の中間の位置にスピンドル５を移動させた場合である。この時スピンドル５に設けられた止水弁６は流水口１４を開放し、水流入口用止水弁７も水流入口４を開放する。従って、給水管９及び分岐路３共に水が流れることになる。
【００１２】
【発明の効果】
本発明によれば、一つのスピンドルの操作だけで、止水栓本体の止水と分岐路の止水とを切り替えることが出来て、操作性に優れた分岐水栓が提供される。また、構造的にも単純になるので、安価なものとなる。
本発明の分岐水栓は、水洗便器の給水配管を分岐して、温水洗浄装置等へ給水するのに特に有用である。
