Description

【０００１】
【発明の属する技術分野】
この発明は、浄水器、食器洗い機、湯沸器、洗濯機などの機器の給水ホースへ給水できる水道用コンセントの配管接続機構に関する。
【０００２】
【従来の技術】
水道用コンセントは、前面に少なくとも二つの開口を有するハウジングと、このハウジングの一方の開口に配置された継手部と、前記ハウジングの他方の開口に配置され、前記継手部から送出する水の流量を調整するためのハンドルとを備えている。そして、水道用コンセントを例えば台所に既設の水栓（湯水混合栓など）の近傍の壁に設置し、水道用コンセントの流入口に、前記既設の水栓に水または湯を供給するために設置されている給水配管から分岐された分岐給水配管を接続することで、例えば浄水器の給水ホースが前記継手部に接続された場合には、前記ハンドル操作にて浄水器に送られる水の量を調整することができる。そして、これにより、前記既設の水栓に浄水器の給水ホースを接続することで浄水器に給水した場合における既設の水栓と浄水器とを同時に使用することができないといった問題点を解消できる。すなわち、水道用コンセントを用いることで前記既設の水栓と浄水器とが同時に使用できる点で利便性がある。
【０００３】
一方、給水と給湯の配管工事に際して、給水主管と、給湯設備からの給湯主管とを屋内に引き込んで、これら給水主管および給湯主管を給水用の配管用ヘッダーおよび給湯用の配管用ヘッダーにそれぞれ接続し、これら各ヘッダーと対応する各水道用コンセントの前記流入口とを接続する水供給管、湯供給管として、架橋ポリエチレンまたは架橋ポリブテンなどの樹脂パイプを蛇腹状の鞘管に挿通して成るものが使用されており、それによって、水漏れ等の場合に鞘管はそのままにして前記樹脂パイプの両端の接続を解除するだけで鞘管内から前記樹脂パイプを取り出し、入れ替えできる点で利便性がある。
【０００４】
【発明が解決しようとする課題】
この場合、樹脂パイプの上流端および下流端はそれぞれヘッダーおよび水道用コンセントの前記流入口に接続されるとともに、鞘管をバンド等の固定手段によって適宜の位置に固定されており、更に、鞘管の上流端は接続部材によってヘッダーに接続されていたけれども、鞘管の下流端だけは水道用コンセントに接続されないままであった。そのため、吐水状態から止水状態への水道用コンセントのハンドル操作で水撃（ウォータハンマ）が発生した際に樹脂パイプが振動し、その振動が鞘管に伝わり、増幅されて数秒ではあるが騒音が発生するという事態に陥る。
【０００５】
本発明は上述の事柄に留意してなされたもので、その目的は、水撃による騒音を低減できる水道用コンセントの配管接続機構を提供することである。
【０００６】
【課題を解決するための手段】
上記目的を達成するために、この発明は、少なくとも二つの開口が前面部に形成されたハウジングと、このハウジング内に設けられ、流入口、流出口および弁体を有する水栓本体と、前記ハウジングの一方の開口に配置され、前記水栓本体の流出口から流出可能な水の流量を調整するための流量調整ハンドルと、この流量調整ハンドルの回動操作を前記弁体に伝達するための伝達機構と、前記水栓本体の流出口に固定されるとともに前記ハウジングの他方の開口に配置され、給水ホースの上流端に設けられた継手部材が着脱自在である継手部とを備えるとともに、
前記水栓本体に、外周面にねじ部を有する外管と、供給管による供給流路を前記流入口に連通させる流路を形成する内管とで構成された接続用筒状部が連設されている水道用コンセントの前記流入口と前記供給管とを接続する水道用コンセントの配管接続機構であって、
前記供給管を、蛇腹状の鞘管と、この鞘管の内部に取り出し可能に挿通された樹脂パイプとで構成するとともに、
鞘管の下流端に外嵌する円筒部材と、
円筒部材を鞘管に固定する手段と、
鞘管に固定された円筒部材が挿入される角筒の連結部材と、
円筒部材を連結部材に固定する手段と、
樹脂パイプの下流端が前記接続用筒状部の前記内管に固定された状態で連結部材をハウジングに取り付ける手段とを備え、
さらに、
円筒部材を連結部材に固定する手段は、円筒部材の外周面に形成されている係止爪と、連結部材に形成され、前記係止爪が係止されるスリットとから構成される一方、
円筒部材を鞘管に固定する手段は、円筒部材の周面に形成されたスリットと、鞘管の下流端の先端面が当接するよう円筒部材に形成された下流側開口と、この下流側開口の内面に鞘管の下流端の先端面を当接させた状態で円筒部材の周面に形成された前記スリットを介して鞘管の溝に係合し、円筒部材を鞘管に位置決め固定しうる位置決め固定部材とから構成されていることを特徴としている（請求項１）。
この発明では、位置決め固定部材はコ字型であり、連結部材は、平面形状が正方形の角筒であり、円筒部材は、連結部材の対向面部の内面に外面が接する径を有し、円筒部材の前記下流側開口が円筒部材の上流側開口よりも小径に形成されており、前記連結部材をハウジングに取り付ける手段は、連結部材の対向面部のうち一方の対向面部の上端でそれぞれ外向き方向に形成されたビス穴を有する接続片と、前記ビス穴に対向するようハウジングの底部に設けたねじ穴と、樹脂パイプの下流端を前記接続用筒状部の前記内管に締め込み、前記ビス穴と前記ねじ穴を介して連結部材をハウジングの底部に取り付けるビスとから構成される一方、連結部材に形成されている前記スリットは、連結部材の対向面部のうち他方の対向面部の下端に当該下端をそれぞれ切り抜いて形成されているのが好ましい（請求項２）。
【０００７】
【発明の実施の形態】
以下、この発明の実施形態を、図を参照しながら説明する。
図１〜図５は、この発明の一実施形態を示す。
図１〜図５において、水道用コンセントＤは、縦に並んだ二つの開口１，２が前面部３に形成されたハウジング４と、このハウジング４内に設けられ、水または湯の流入口５および流出口６ならびにカートリッジ式の弁体８を有する水栓本体７と、前記ハウジング４の一方の開口１に配置され、前記水栓本体７の流出口６から流出可能な水の流量を調整するための流量調整操作部材であるダイヤル型の流量調整ハンドル９と、この流量調整ハンドル９の回動操作を前記弁体８に伝達するための伝達機構（特願２０００− ３４９３号の明細書、図面参照）１０と、前記水栓本体７の流出口６に固定されるとともに前記ハウジング４の他方の開口２に配置され、給水ホースＨの上流端に設けられた継手部材Ｈ’が着脱自在である継手部１１とを備えている。
【０００８】
前記開口１，２は、正面視がほぼ円形状となるように形成されている。
【０００９】
前記前面部３は、前記開口１，２が形成されている中央部３ａと、この中央部３ａを保持するための枠体３ｂとからなる。
【００１０】
前記ハウジング４は、ほぼ直方体形状であり、前記前面部３と、この前面部３が着脱可能なハウジング本体１４とからなる。
【００１１】
前記流入口５には後述する接続用筒状部５０を介して水供給管１３の下流端１３ａが接続されている。この水供給管１３の上流端は、屋内に引き込まれた給水主管に接続されている給水用の配管用ヘッダー（図示せず）に接続されている。
【００１２】
前記水栓本体７は、前記ハウジング本体１４の底部に固定されており、前記水供給管１３からの水が、流入口５から内部に導入され、流出口６から下流側へ送出される構成となっている。
【００１３】
前記カートリッジ式の弁体８は、水栓本体７の内部に挿入されており、その軸心回りに回転可能な筒体１５を有している。そして、前記流入口５から水栓本体７内に至った水は、筒体１５の内部と、前記筒体１５の側壁に形成され、流出口６に連通する貫通孔（図示せず）とを経た後に流出口６から送出されるように構成されており、前記筒体１５の回動操作に伴って、流出口６と貫通孔との重なり部分の大きさが変化するため、水栓本体７内から流出口６に送出可能な水の流量も変化することになる。従って、筒体１５の回動操作を行うことにより、流出口６から送出される水の流量を調整することができる。なお、流出口６は例えば浄水器の給水ホースに接続されている。
【００１４】
前記水供給管１３は、たとえば水道用架橋ポリブテン管または水道用架橋ポリエチレン管の樹脂パイプ１８を蛇腹状の鞘管１９の内部に収容してなり、樹脂パイプ１８は鞘管１９によって配管経路上にガイドされるとともに保護されている。前記水供給管１３はバンド等の固定手段（図示せず）によって適宜の位置に固定されている。樹脂パイプ１８の上流端および鞘管１９の上流端は、それぞれ接続部材で前記ヘッダーに接続されている。
【００１５】
前記接続用筒状部５０は、水道用コンセントＤの前記水栓本体７の前記流入口５から下方に連設されており、前記水栓本体７と水供給管１３を接続する。この筒状部５０は、外周面に雄ねじ５１を有する外管５２と、前記水供給管１３による供給流路ｉを前記流入口５に連通させる流路ｊを形成する内管５３とで構成されている。
【００１６】
この内管５３は、外管５２よりも下方に長さｄだけ突出している。前記外管５２の下端（先端）は内側に外向きテーパ面ｍ〔図２（Ｂ）参照〕を有する。そして、水栓本体７と水供給管１３の接続時において、前記樹脂パイプ１８の下流端１８ａを前記内管５３に外嵌させる。
【００１７】
５４は、外管５２の外周面に形成された前記雄ねじ５１に螺着される袋ナットで、雌ねじ５５の下に内向きテーパ面ｎ〔図２（Ｂ）参照〕が形成されている。
【００１８】
５６は金属製の縮径可能な割りリングで、樹脂パイプ１８の下流端１８ａの位置における外周面ａに嵌め込まれ、樹脂パイプ１８の下流端１８ａを前記内管５３に外嵌させた後外管５２の前記外向きテーパ面ｍによって下流側への移動を阻止される。すなわち、割りリング５６は、一端に前記テーパ面ｍに当接するテーパ面ｂ〔図２（Ｂ）参照〕を有する。また、割りリング５６は、他端に袋ナット５４の前記内向きテーパ面ｎが当接するテーパ面ｃ〔図２（Ｂ）参照〕を有する一方、内周面に複数段の環状突起８０を有し、これにより、袋ナット５４の締め込みによって樹脂パイプ１８の下流１８ａを内管５３に強固に固定することができる。
【００１９】
次に、この発明の特徴的構成について説明する前に図４、図５を用いて水道用コンセントＤの取り付け方について説明する。
【００２０】
水道用コンセントＤは、前記ハウジング４の前面部３が壁Ｗの前面とほぼ面一となるように壁Ｗ内に配置され、かつ、間柱Ｐに対して、直接取り付けられる。
【００２１】
水道用コンセントＤのハウジング本体１４の側壁には、三方が切り欠かれ、かつハウジング本体１４の内側に折れ曲げられ、平面視がほぼへの字形状となっている折れ曲がり部７０が形成されており、この折れ曲がり部７０は、ネジ７１が挿通可能な穴７１’を有している。そして、水道用コンセントＤを間柱Ｐに取り付けるには、ハウジング４の前記折れ曲がり部７０が形成されている側壁を間柱Ｐに当接させ、穴７１’を挿通させたネジ７１で止めればよい。なお、穴７１’は、折れ曲がり部７１の前側の傾斜した面に形成されていることから、前記ネジ７１を用いたハウジング本体１４の取り付け作業を簡単に行うことが可能である。
【００２２】
また、ハウジング本体１４の側壁には、前後方向において自在に位置決め可能なはさみ板７２が設けられており、このはさみ板７２と前記前面部３の枠体３ｂとで壁Ｗをはさみこむことが可能である。
【００２３】
そして、上記のように間柱Ｐに取り付けられたハウジング本体１４に前面部３を取り付けるには、壁Ｗの前側から壁Ｗを挿通させた枠体３ｂの後部をハウジング本体１４内に嵌め込み、前記はさみ板７２と枠体３ｂとで壁Ｗをはさみこんだ後、適宜にネジ止めを行い、最後に前面部３の中央部３ａを枠体３ｂに取り付けるだけでよい。
【００２４】
水道用コンセントＤを壁Ｗだけに取り付けた場合には、水道用コンセントＤに対して給水ホースＨを取り外しすることが、壁Ｗを押したり引いたりする動作につながるため、特に壁Ｗが薄かったり頑丈でなかったりすると、壁Ｗがすぐに劣化してしまい、このような壁Ｗの劣化によって、水道用コンセントＤががたつくようになり、また、壁Ｗと水道用コンセントＤとの間に隙間が生じ、そこから水や煙などが侵入するおそれがあるが、上記のように、水道用コンセントＤを間柱Ｐと壁Ｗとに固定していることから、水道用コンセントＤを壁Ｗに対してのみ取り付けている場合に比べて、よりがたつきが無い状態で保持することができ、また、水や煙などの侵入を確実に防止することができる。
【００２５】
以下、この発明の特徴的構成について説明する。
【００２６】
２０は、鞘管１９の下流端１９ａを水道用コンセントＤのハウジング本体１４に接続する取付部材である。この取付部材２０は、例えば平面形状が正方形の角筒で、一方の対向面部ａ，ｂの上端にそれぞれビス穴２１が形成された接続片２２を外向き方向に有する一方、他方の対向面部ｃ，ｄの下端に当該下端をそれぞれ切り抜いて形成された係止用のスリット２３を有する連結部材２４と、この連結部材２４の前記対向面部ａ，ｂ，ｃ，ｄの内面に外面が接する径を有し、下流側開口ｅが上流側開口ｆよりも小径に形成されている円筒部材２５とで主として構成されている。前記スリット２３は、Ｌ型であり、縦スリット部分２３ａおよび横スリット部分２３ｂよりなる。２３ｃは、前記両スリット部分２３ａ，２３ｂ間に形成された抜け止め片である。この抜け止め片２３ｃは、スリット部分２３ｂに位置した後述する係止爪３１がスリット２３から抜けてしまうのを防止する機能を有する。
【００２７】
前記円筒部材２５は、連結部材２４内に挿入したときに円筒部材２５外面が連結部材２４の対向面部ａ，ｂ，ｃ，ｄの内面に接する程度に遊嵌可能な大きさに設定されている。そして、前記円筒部材２５の上流端外面には、対向する形で一対の平坦面部３０が形成されている。
【００２８】
また、前記円筒部材２５は、周面に、前記スリット２３に係合する一対の係止爪３１を有する。この係止爪３１は、前記平坦面部３０の直下流側にそれぞれ設けられている。つまり、円筒部材２５を連結部材２４へ挿入して所定位置にセットした状態では、前記係止爪３１は連結部材２４の対向面部ｃ，ｄの側に位置する。
【００２９】
更に、前記円筒部材２５の周面には、鞘管１９の溝Ｍに係合して円筒部材２５を鞘管１９に位置決め固定するための一対の位置決め固定部材３３用の上下二つのスリット３４が形成されている。つまり、円筒部材２５を連結部材２４へ挿入して所定位置にセットした状態では、固定部材３３およびスリット３４は連結部材２４の対向面部ａ，ｂの側に位置する。前記位置決め固定部材３３はコ字型をなす。
【００３０】
３６は、連結部材２４をハウジング本体１４の底部１４ａに設けたねじ穴３７に螺合するビスである。
【００３１】
そして、前記連結部材２４、円筒部材２５、ビス３６、ねじ穴３７、位置決め固定部材３３から前記取付部材２０が構成されている。
【００３２】
而して、間柱Ｐに取り付けられた水道用コンセントＤに水供給管１３を接続するには、図３に示すように、樹脂パイプ１８の下流端１８ａを袋ナット５４を用いて接続用筒状部５０に締め込む前に、まず、円筒部材２５を水供給管１３に外嵌し、円筒部材２５の下流側開口ｅの内面を鞘管１９の下流端１９ａの先端面に当接させながら、位置決め固定部材３３を用いて円筒部材２５を鞘管１９に位置決め固定する。
【００３３】
続いて、円筒部材２５の前記平坦面部３０を保持しながら円筒部材２５を連結部材２４に挿入するとともに、係止爪３１をスリット２３内に位置させる。この状態は、図５に示されている。最後に、樹脂パイプ１８の下流端１８ａを接続用筒状部５０に締め込み、ビス３６にて連結部材２４をハウジング本体１４に取り付ける。
【００３４】
このように、鞘管１９の下流端１９ａを円筒部材２５、連結部材２４を介してハウジング本体１４に固定したので、吐水状態から止水状態への水道用コンセントのハンドル操作で水撃（ウォータハンマ）が発生した際に樹脂パイプが振動してもその騒音を低減できる。
【００３５】
上記実施形態では、鞘管１９の下流端１９ａを水道用コンセントＤに接続するにあたり、（１）鞘管１９の溝Ｍに、円筒部材２５に備わっているコ字型の固定部材３３を係合させ、（２）続いて、円筒部材２５に形成されている係止爪３１を連結部材２４のスリット部分２３ｂに係止させ、（３）接続用筒状部５０の袋ナット５４の締め込みによって樹脂パイプ１８の下流端１８ａを接続用筒状部５０の内管５３に固定し、（４）最後に、ビス３６を連結部材２４に形成したビス穴２１を介して、ハウジング本体１４の底面１４ａに形成したねじ穴３７に締付けるといった四つの繋ぎ動作を行う必要がある。
【００３６】
図６〜図８は、鞘管１９の下流端１９ａを水道用コンセントＤに容易に接続できるように構成した参考例を示す。図において、図１〜図５に示した符号と同一のものは同一または相当物である。
【００３７】
図６〜図８において、８０は、鞘管１９の下流端１９ａを水道用コンセントＤに接続するための取付部材である。この取付部材８０は、ハウジング本体１４の底面１４ａにスポット溶接により連結された連結部材８２と、筒状で、連結部材８２に着脱可能に装着される鞘管ホルダ８４とから構成される。８５は、連結部材８２のスポット溶接予定位置である。
【００３８】
前記鞘管ホルダ８４は、上流側から下流側に向かって鞘管１９を途中まで押し込めるとともに鞘管１９内の樹脂パイプ１８を挿通させる供給管挿通穴８３を中央に有するとともに、三分割可能に構成されている。
【００３９】
すなわち、鞘管ホルダ８４は、筒状胴部８５と、この上端に形成された上ネジ部８４ａに螺合する上部リング体８６と、前記胴部８５の下端に形成された下ネジ部８４ｂに螺合する下部リング体８７と、後述する割りリング８９とよりなる。
【００４０】
更に、前記胴部８５は、前記上ネジ部８４ａと、これより大径の円筒部材２５’と、前記下ネジ部８４ｂとよりなる。前記胴部８５は、円筒部材２５’と前記下ネジ部８４ｂの間に外向きフランジ８８ａを有する。前記供給管挿通穴８３の一部を構成する円筒部材２５’の貫通穴８３ａは、内面上端が、鞘管１９の下流端１９ａを下部リング体８７の貫通穴から押し込んだときに下流端１９ａの先端部分Ｘが当接する環状当接面Ｙを有するよう形成されている。
【００４１】
また、下部リング体８７には、複数の舌片８８が円周に沿う形で等間隔に形成された割りリング８９が嵌め込まれている。前記各舌片８８は、径方向で内向き、かつ、上方傾斜した状態で設けられている。
【００４２】
前記各舌片８８は、鞘管１９の下流端１９ａが円筒部材２５’の前記貫通穴８３ａに押し込まれた後、鞘管１９の溝Ｍに係合して鞘管１９を円筒部材２５’内に位置決め固定するとともに、鞘管１９が反対方向に抜けるのを防止する機能を有する。
【００４３】
一方、前記連結部材８２は、正面視門型で、底面部８２ａに開口９０を有するとともに、対向する両側面部９１，９２を有する。すなわち、連結部材８２は、例えば一枚の横長の長方形の板部材を長手方向において二箇所１００，２００を互いに対向するよう反対方向に直角に折り曲げて対向する側面部９１および側面部９２を形成するとともに、側面部９１の端を外側に直角に折り曲げて接続片９１ａを形成し、かつ、側面部９２の端を外側に直角に折り曲げて接続片９２ａを形成してなる。すなわち、側面部９１は、前記スポット溶接予定位置８５が位置する接続片９１ａを外向き方向に有する一方、側面部９２は、前記スポット溶接予定位置８５が位置する接続片９２ａを外向き方向に有する。
【００４４】
更に、前記開口９０は、前記胴部８５の上ネジ部８４ａが外嵌可能な径を有するとともに、円筒部材２５’は上ネジ部８４ａよりも大径であるので、上ネジ部８４ａを底面部８２ａの下方側から開口９０に嵌め込んだときに円筒部材２５’の鍔８８ａの上面に開口９０端が当接する。この状態で、上ネジ部８４ａに上部リング体８６を螺合させることにより、円筒部材２５’と上ネジ部８４ａを連結部材８２の底面部８２ａに固定できる。
【００４５】
而して、水道用コンセントＤの施工時に鞘管１９の下流端１９ａを水道用コンセントＤに接続するには、
（１）予め水栓本体７が取り外された状態で、かつ、連結部材８２が底面１４ａにスポット溶接されているハウジング本体１４を例えば間柱Ｐに対して、直接取り付けておく。この場合、鞘管ホルダ８４を開口９０を介して連結部材８２の底面部８２ａに予め固定しておく。なお、下部リング体８７を下ネジ部８４ｂに仮止め状態で螺合させておく。
【００４６】
（２）続いて、鞘管１９を鞘管ホルダ８４の供給管挿通穴８３に押し込む。この場合、下流端１９ａの先端部分Ｘが円筒部材２５’の前記貫通穴８３ａの前記環状当接面Ｙに当接するまで鞘管１９の下流端１９ａが円筒部材２５’の前記貫通穴８３ａに押し込まれる。
【００４７】
（３）続いて、胴部８５の前記下ネジ部８４ｂに、複数の舌片８８が形成された割りリング８９を有する下部リング体８７を螺合する。この下部リング体８７の締め込みによって複数の舌片８８が鞘管１９の溝Ｍに強固に係合することで鞘管１９の下流端１９ａが鞘管ホルダ８４内に確実に固定することができる。すなわち、鞘管１９の下流端１９ａを円筒部材２５’内に確実に位置決め固定するとともに、鞘管１９が反対方向に抜けるのを防止できる。
【００４８】
（４）その後、鞘管１９内の樹脂パイプ１８を鞘管ホルダ８４の供給管挿通穴８３から引き出した状態で、上記第１の実施形態と同様に、予め水栓本体７に接続されている接続用筒状部５０の袋ナット５４の締め込みによって樹脂パイプ１８の下流端１８ａを接続用筒状部５０の内管５３に固定する。
【００４９】
（５）最後に、間柱Ｐに既に固定されているハウジング本体１４に樹脂パイプ１８が接続された状態の水栓本体７を取り付ける。
【００５０】
この参考例では、鞘管１９の下流端１９ａをハウジング本体１４に固定したので、吐水状態から止水状態への水道用コンセントのハンドル操作で水撃（ウォータハンマ）が発生した際に樹脂パイプが振動してもその騒音を低減できる上に、上記第１の実施形態の場合よりも鞘管１９の下流端１９ａと水道用コンセントＤの接続動作が容易に行える利点を有する。
【００５１】
更に、この参考例では、連結部材８２を正面視門型に形成しており、連結部材８２を接続片９１ａ，９２ａを介してハウジング本体１４の底面１４ａに取り付けた状態では、対向する両側面部９１，９２間の前面と後面に、両側面部９１，９２と底面８２ａと底面１４ａ間に形成される空間Ｓに連通する前開口３９９および後開口４００が形成されることから、施工後のメンタナンスのために樹脂パイプ１８が接続された状態の水栓本体７を前方側に傾けた状態でハウジング本体１４から容易に取り外すことが利点を有する。
【００５２】
その手順について以下に説明する。
【００５３】
例えば、古い樹脂パイプ１８を取り替える必要がある場合、（１）壁Ｗの設置開口Ｗ_a（図５参照）を介してハウジング本体１４から前面部３ａ，３ｂを取り外し、古い樹脂パイプ１８が接続された状態の水栓本体７をハウジング本体１４から取り外すと、図８に示す状態になる。
【００５４】
（２）この場合、図８に示すように、樹脂パイプ１８が接続された状態の水栓本体７を前方側に傾けた状態でハウジング本体１４から取り外す必要がある。すなわち、図６において、水栓本体７はハウジング本体１４にビス３００で固定されているので、まず、ビス３００を取り外した後、前方側に傾けた状態で古い樹脂パイプ１８付きの水栓本体７を取り外す。つまり、水栓本体７をハウジング本体１４内で前方に傾けても、後方側に傾く接続用筒状部５０は後開口４００を通過することになるから、連結部材８２によって接続用筒状部５０の傾き動作が阻止されることはなく、水栓本体７のハウジング本体１４内からの取り外し動作を容易にできる。同様に、水栓本体７のハウジング本体１４内への収容動作も容易にできる。
なお、古い樹脂パイプ１８の他端、すなわち、樹脂パイプ１８の下流端１８ａとは反対側の樹脂パイプ１８の上流端（図示せず）と例えば給湯器との接続も解除されている。この状態で、水栓本体７をハウジング本体１４から取り外し、接続用筒状部５０の袋ナット５４を弛めて樹脂パイプ１８の下流端１８ａを引き抜くことで、古い樹脂パイプ１８を取り出せる。
【００５５】
（３）次に、新品の樹脂パイプを給湯器側から鞘管１９内を挿通させて鞘管１９の下流端１９ａより樹脂パイプを突出させ、これを接続用筒状部５０に接続し、水栓本体７をハウジング本体１４に取り付ける。
【００５６】

The water outlet is a housing having at least two openings on the front surface, a joint portion disposed in one opening of the housing, and a flow rate of water sent from the joint portion disposed in the other opening of the housing. And a handle for adjustment. A water outlet is installed on the wall near the existing faucet (hot water mixing faucet, etc.) in the kitchen, for example, and is installed at the inlet of the water outlet to supply water or hot water to the existing faucet. For example, when a water supply hose of a water purifier is connected to the joint part by connecting a branched water supply pipe branched from the water supply pipe, the amount of water sent to the water purifier by the handle operation is reduced. Can be adjusted. And the problem that the existing faucet and the water purifier cannot be simultaneously used when water is supplied to the water purifier by connecting the water hose of the water purifier to the existing faucet can be solved. That is, it is convenient in that the existing faucet and the water purifier can be used simultaneously by using a water outlet.

[0019]
Next, before explaining the characteristic configuration of the present invention, how to attach the water outlet D will be described with reference to FIGS.
[0020]
The water outlet D is disposed in the wall W so that the front surface portion 3 of the housing 4 is substantially flush with the front surface of the wall W, and is directly attached to the stud P.
[0021]
On the side wall of the housing main body 14 of the water outlet D, there is formed a bent portion 70 that is cut out in three directions and bent inside the housing main body 14 so as to have a substantially square shape in plan view. The bent portion 70 has a hole 71 ′ through which a screw 71 can be inserted. In order to attach the water outlet D to the stud P, the side wall of the housing 4 on which the bent portion 70 is formed may be brought into contact with the stud P and fixed with the screw 71 through which the hole 71 ′ is inserted. Since the hole 71 ′ is formed on the inclined surface on the front side of the bent portion 71, the mounting work of the housing body 14 using the screw 71 can be easily performed.

[0024]
When the water outlet D is attached only to the wall W, removing the water supply hose H from the water outlet D leads to an operation of pushing or pulling the wall W, so that the wall W is particularly thin. If it is not sturdy, the wall W will deteriorate immediately, and the deterioration of the wall W will cause the water outlet D to rattle, and there will be a gap between the wall W and the water outlet D. There is a risk that water, smoke, etc. may enter from there, but since the water outlet D is fixed to the stud P and the wall W as described above, the water outlet D is connected to the wall W. Compared with the case where it only attaches, it can hold | maintain in the state without rattling, and can prevent invasion of water, smoke, etc. reliably.

The cylindrical member 25 is set to a size that allows loose fitting so that the outer surface of the cylindrical member 25 is in contact with the inner surfaces of the opposing surface portions a, b, c, and d of the connecting member 24 when inserted into the connecting member 24. . Then, the upstream end an outer surface on the cylindrical member 25 has a pair of flat surface portions 30 is formed so as to be opposed.
[0028]
The cylindrical member 25 has a pair of locking claws 31 that engage with the slit 23 on the peripheral surface. The locking claws 31 are respectively provided on the downstream side of the flat surface portion 30. That is, in a state where the cylindrical member 25 is inserted into the connecting member 24 and set at a predetermined position, the locking claw 31 is located on the facing surface portions c and d side of the connecting member 24.
[0029]
Further, on the peripheral surface of the cylindrical member 25, there are two upper and lower slits 34 for a pair of positioning fixing members 33 for engaging with the groove M of the sheath tube 19 to position and fix the cylindrical member 25 to the sheath tube 19.

This state is shown in FIG. Finally, the downstream end 18 a of the resin pipe 18 is fastened to the connecting tubular portion 50, and the connecting member 24 is attached to the housing body 14 with screws 36.
[0034]
Thus, since the downstream end 19a of the sheath tube 19 is fixed to the housing body 14 via the cylindrical member 25 and the connecting member 24, the water hammer (water hammer) can be operated by operating the handle of the water outlet from the water discharge state to the water stop state. ), The noise can be reduced even if the resin pipe vibrates.
[0035]
Above you facilities embodiment, the downstream end 19a of the sheath tube 19 Upon connecting to a water outlet D, and (1) in the groove M of the sheath tube 19, the fixed member 33 of the U-shaped are provided on the cylindrical member 25 (2) Subsequently, the locking claw 31 formed on the cylindrical member 25 is locked to the slit portion 23b of the connecting member 24, and (3) the cap nut 54 of the connecting tubular portion 50 is tightened. The downstream end 18a of the resin pipe 18 is fixed to the inner pipe 53 of the connecting tubular portion 50 by (4), and (4) finally, the screw 36 is formed in the connecting member 24 through the screw hole 21 of the housing main body 14. It is necessary to perform four connecting operations such as tightening into the screw holes 37 formed in the bottom surface 14a.
[0036]
FIGS. 6-8 shows the reference example comprised so that the downstream end 19a of the sheath pipe 19 could be easily connected to the outlet D for water supply. In the figure, the same reference numerals as those shown in FIGS. 1 to 5 are the same or equivalent.
[0037]
6 to 8, reference numeral 80 denotes an attachment member for connecting the downstream end 19 a of the sheath pipe 19 to the water outlet D. The attachment member 80 includes a connection member 82 connected to the bottom surface 14a of the housing main body 14 by spot welding, and a sheath-tube holder 84 that is cylindrical and is detachably attached to the connection member 82. Reference numeral 85 denotes a spot welding scheduled position of the connecting member 82.
[0038]
The sheath tube holder 84 has a supply tube insertion hole 83 at the center for pushing the sheath tube 19 halfway from the upstream side toward the downstream side and through which the resin pipe 18 in the sheath tube 19 is inserted, and can be divided into three parts. Has been.
[0039]
That is, the sheath tube holder 84 includes a cylindrical body portion 85, an upper ring body 86 that is screwed into the upper screw portion 84a formed at the upper end, and a lower screw portion 84b that is formed at the lower end of the body portion 85. It consists of a lower ring body 87 to be screwed and a split ring 89 to be described later.
[0040]
Furthermore, the trunk portion 85 includes the upper screw portion 84a, a cylindrical member 25 ′ having a larger diameter than the upper screw portion 84a, and the lower screw portion 84b. The trunk portion 85 has an outward flange 88a between the cylindrical member 25 ′ and the lower screw portion 84b . The through hole 83 a of the cylindrical member 25 ′ constituting a part of the supply pipe insertion hole 83 has an upper end on the inner surface of the downstream end 19 a when the downstream end 19 a of the sheath pipe 19 is pushed from the through hole of the lower ring body 87. It is formed so as to have an annular contact surface Y with which the tip portion X contacts.
[0041]
The lower ring body 87 is fitted with a split ring 89 in which a plurality of tongue pieces 88 are formed at equal intervals along the circumference. Each of the tongue pieces 88 is provided in a radially inward and inclined upward state.
[0042]
Each tongue piece 88 is engaged with the groove M of the sheath tube 19 after the downstream end 19a of the sheath tube 19 is pushed into the through hole 83a of the cylindrical member 25 ', and the sheath tube 19 is inserted into the cylindrical member 25'. And has a function of preventing the sheath tube 19 from coming off in the opposite direction.
[0043]
On the other hand, the connecting member 82 is a front view portal type, has an opening 90 in the bottom surface portion 82a, and has opposite side surface portions 91, 92. That is, the connecting member 82, for example, forms a laterally long rectangular plate member by bending the two portions 100 and 200 in the longitudinal direction at right angles in opposite directions so as to face each other. At the same time, the connection piece 91a is formed by bending the end of the side surface portion 91 outward at a right angle, and the connection piece 92a is formed by bending the end of the side surface portion 92 at a right angle. That is, the side surface portion 91 has the connection piece 91a where the spot welding scheduled position 85 is located in the outward direction, while the side surface portion 92 has the connection piece 92a where the spot welding planned position 85 is located in the outward direction. .
[0044]
Furthermore, the opening 90 has a diameter that allows the upper threaded portion 84a of the body 85 to be fitted outside, and the cylindrical member 25 'has a larger diameter than the upper threaded portion 84a. When fitted into the opening 90 from the lower side of 82a, the end of the opening 90 comes into contact with the upper surface of the flange 88a of the cylindrical member 25 ′. In this state, the cylindrical member 25 ′ and the upper screw portion 84 a can be fixed to the bottom surface portion 82 a of the connecting member 82 by screwing the upper ring body 86 into the upper screw portion 84 a.
[0045]
Thus, to connect the downstream end 19a of the sheath pipe 19 to the water outlet D at the time of construction of the water outlet D,
(1) The housing body 14 in which the faucet body 7 has been removed in advance and the connecting member 82 is spot-welded to the bottom surface 14a is directly attached to the stud P, for example. In this case, the sheath tube holder 84 is fixed in advance to the bottom surface portion 82 a of the connecting member 82 through the opening 90. The lower ring body 87 is screwed to the lower screw portion 84b in a temporarily fixed state.
[0046]
(2) Subsequently, the sheath tube 19 is pushed into the supply tube insertion hole 83 of the sheath tube holder 84. In this case, the downstream end 19a of the sheath tube 19 is pushed into the through hole 83a of the cylindrical member 25 'until the distal end portion X of the downstream end 19a contacts the annular contact surface Y of the through hole 83a of the cylindrical member 25'. It is.
[0047]
(3) Subsequently, a lower ring body 87 having a split ring 89 formed with a plurality of tongue pieces 88 is screwed into the lower screw portion 84b of the body portion 85. By tightening the lower ring body 87, the plurality of tongue pieces 88 are firmly engaged with the groove M of the sheath tube 19, so that the downstream end 19 a of the sheath tube 19 can be securely fixed in the sheath tube holder 84. . That is, the downstream end 19a of the sheath tube 19 can be reliably positioned and fixed in the cylindrical member 25 ′, and the sheath tube 19 can be prevented from coming off in the opposite direction.
[0048]
(4) After that, in the state where the resin pipe 18 in the sheath pipe 19 is pulled out from the supply pipe insertion hole 83 of the sheath pipe holder 84, it is connected to the faucet body 7 in advance as in the first embodiment. The downstream end 18 a of the resin pipe 18 is fixed to the inner pipe 53 of the connecting tubular portion 50 by tightening the cap nut 54 of the connecting tubular portion 50.
[0049]
(5) Finally, the faucet body 7 in a state where the resin pipe 18 is connected to the housing body 14 already fixed to the stud P is attached.
[0050]
In this reference example , since the downstream end 19a of the sheath pipe 19 is fixed to the housing main body 14, when the water hammer (water hammer) is generated by the handle operation of the water outlet from the water discharge state to the water stop state, the resin pipe is Even if it vibrates, the noise can be reduced, and there is an advantage that the operation of connecting the downstream end 19a of the sheath tube 19 and the water outlet D can be performed more easily than in the case of the first embodiment.
[0051]
Further, in this reference example , the connecting member 82 is formed in a front view type, and when the connecting member 82 is attached to the bottom surface 14a of the housing main body 14 via the connecting pieces 91a and 92a, the opposite side surface portions 91 facing each other. , 92 are formed with a front opening 399 and a rear opening 400 communicating with the space S formed between the side surface portions 91, 92, the bottom surface 82a, and the bottom surface 14a. It is advantageous to easily remove the faucet body 7 with the resin pipe 18 connected thereto from the housing body 14 in a state where the faucet body 7 is inclined forward.
[0052]
The procedure will be described below.
[0053]
For example, when it is necessary to replace the old resin pipe 18, (1) the front portions 3 a and 3 b are removed from the housing body 14 through the installation opening W _a (see FIG. 5) of the wall W, and the old resin pipe 18 is connected. When the water faucet body 7 is removed from the housing body 14, the state shown in FIG. 8 is obtained.
[0054]
(2) In this case, as shown in FIG. 8, it is necessary to remove the faucet body 7 with the resin pipe 18 connected thereto from the housing body 14 in a state where the faucet body 7 is tilted forward. That is, in FIG. 6, since the faucet body 7 is fixed to the housing body 14 with screws 300, first, after removing the screws 300, the faucet body 7 with the old resin pipe 18 is tilted forward. Remove. That is, even if the faucet body 7 is tilted forward in the housing body 14, the connecting tubular portion 50 that tilts backward passes through the rear opening 400. Therefore, it is possible to easily remove the faucet body 7 from the housing body 14. Similarly, the operation of accommodating the faucet body 7 in the housing body 14 can be facilitated.
The connection between the other end of the old resin pipe 18, that is, the upstream end (not shown) of the resin pipe 18 opposite to the downstream end 18 a of the resin pipe 18, for example, is also released. In this state, the faucet body 7 is removed from the housing body 14, the cap nut 54 of the connecting tubular portion 50 is loosened, and the downstream end 18 a of the resin pipe 18 is pulled out, whereby the old resin pipe 18 can be taken out.
[0055]
(3) Next, a new resin pipe is inserted through the sheath pipe 19 from the hot water supply side so that the resin pipe protrudes from the downstream end 19a of the sheath pipe 19 and is connected to the connecting tubular portion 50. The stopper body 7 is attached to the housing body 14.
[0056]
【The invention's effect】
In this invention, since the downstream end of the sheath pipe communicating with the inlet of the water outlet is connected to the housing of the water outlet by the mounting member, noise due to water hammer can be reduced.
