【発明の属する技術分野】
本発明は、壁体に取付ける、機能部が露出した露出型混合水栓（以下、特に露出形と明示する必要や後述の２穴式と１穴式を区別する必要がある場合を除き、略称して混合水栓と呼ぶ）の取付構造に関するものである。なお、ここにいう壁体とは、壁、カウンター、浴槽等、混合水栓を取付けるための面を有するもの全般を指し、混合水栓を取付ける面が、鉛直面、水平面、斜面の何れであるかは問わないし、混合水栓は、壁体裏面側の配管と壁体表面側の混合水栓とを連結する貫通継手（以下、請求項を引用したり、水側と湯側を区別する必要がある場合を除き、略称して継手と呼ぶ）が貫通する壁開口を、水側及び湯側に別々に設ける２穴式であるか、一つの壁開口で共用する１穴式であるかも問わない。
【０００２】
【従来の技術】
Ａ）従来から、壁体に単水栓や２穴式露出型混合水栓を取付固定するために壁体に設ける継手の取付構造は、特開昭６３−１４２１３４「ユニットバス用水栓取付ボックスの仮固定構造」、特開平９−１５２０５８「継手収納ボックス内への継手の固定構造」、特開平１０−７２８５２「壁用水栓取付け装置」、特開平３−６９７３４「流体配管用の中継接続具」等、数多く提案されているが、何れも、水栓は継手を介して壁体に取付固定するため、継手も、壁体や壁体の支持材類に強固に取付固定するようになっている。
【０００３】
Ｂ）一方、壁体等に取付固定された水側と湯側の一対の継手に混合水栓本体を取付固定するためには、継手の芯間と混合水栓本体入口側の芯間を合せるため、通常は、図９に示す、ＪＩＳ Ｂ２０６１「給水栓」の「付属書８（参考） 給水栓の形状」の「壁付きサーモスタット湯水混合水栓」等のように、一対の、クランク状に曲がった連結部品９００を介して、継手と混合水栓本体８００とを連結する。
【０００４】
Ｃ）又、クランク状部品をなくすため、特開平９−３９９３「水栓取付具」のように、正確な間隔を得るために、継手をフランジで連結したものや、特開平８−１８４０８２「湯水混合水栓用水栓エルボの固定構造及び取付脚の接続構造」のように、継手の間隔を調節可能に成す保持部を有するものがある。
Ｄ）更に、１穴式の混合水栓にあっては、特開平１−２９９９２７「混合水栓への湯水供給装置」や特開平１１−３６３９２「湯水混合水栓の接続構造」のように、水側と湯側が一体となった継手と混合水栓本体とを接続するものがある。
【０００５】
【発明が解決しようとする課題】
Ａ）の継手の取付構造では、継手を、壁体や壁体の支持材類に強固に取付固定するため、一対の継手の間隔は完全に固定され、しかも、継手の取付固定作業も施工現場での作業となるため、精度が出にくいので、混合水栓本体入口側の間隔と一致せず、混合水栓本体を取付固定できないという不具合が発生する可能性が大きい。
【０００６】
このため、Ｂ）のように、クランク状に曲がった連結部品９００を介して、継手と混合水栓本体８００とを連結することが行われるが、その調整作業にはかなりの熟練を要するばかりか、漏水の可能性も大きく、又、壁体と混合水栓本体８００との間に一対の連結部品９００があり、しかも形状が複雑なため、コスト、意匠、清掃性の面で問題がある。
【０００７】
この問題を解決するために、Ｃ）が提案されているが、前者では、継手の間隔及び混合水栓本体入口側の間隔の双方に、高度な寸法精度を要求するため、製造コストの上昇を招くという問題がある。又、後者では、一般的なＡ）より、継手の間隔調整がやり易い分、施工性が向上しているが、壁体施工後に壁体前面側から調整することはできないため、継手の間隔を予め混合水栓本体入口側の間隔に正確に合せておく必要があり、これを忘れたり、疎かにすると、壁体裏面側に回れない場合は、手の施しようがなくなる可能性もある。
【０００８】
Ｄ）では、水側と湯側の継手が一体のため、混合水栓本体入口側との取合において、寸法的な遊びが取り難く、高度な寸法精度が要求され、製造及び取付施工の困難さと、それに伴うコストの上昇を招き、かつ、製造及び施工精度不良に伴う漏水の可能性が大きいという問題がある。
【０００９】
なお、上記何れの従来技術でも、継手は回動不能に取付固定されているため、配管取出方向の自由度が制限されるとともに、配管の曲がりや捩じれ等による反発力等のために、継手を所定の向きに取付固定する作業が困難で、施工コストの上昇を招くという問題もある。
【００１０】
本発明は、上記課題を解決するためになされたもので、本発明の目的は、１穴式、２穴式に拘わらず、製造や施工が容易で、意匠性、清掃性が良く、漏水の可能性が小さく、安価な混合水栓の取付構造を提供することにある。
【００１１】
【課題を解決するための手段】

また、請求項５記載の混合水栓の取付構造では、前記水栓取付座を、前記壁開口を通して前記壁裏当て材に連結固定することを特徴とすることとした。

【００１３】
【発明の実施の形態】
壁体に開設した壁開口と、この壁開口を貫通する貫通継手と、継手出口側に接続する混合水栓本体を有する混合水栓の取付構造では、継手が一体の時には、継手出口側と混合水栓入口側との取合において、寸法的な遊びが取り難く、高度な寸法精度が要求され、製造及び取付施工の困難さと、それに伴うコストの上昇を招き、かつ、製造及び施工精度不良に伴う漏水事故の可能性が大きいという問題があるが、これを解決するために、水側及び湯側の貫通継手を互いに分離独立した別体品とした。更に、分離独立した一対の継手出口側を壁開口から同時に引き出せるように、又、配管に取付けた継手が自立し所定の位置に留まり易いようにして施工を容易にし、施工コストの低減を図るため、壁体裏面側に壁裏当て材を設けて、一対の継手出口側を略所定の間隔に保持して緩やかに一体化した。なお、略所定の間隔に保持するとは、所定の間隔に動かないように固定するのではなく、所定の間隔よりやや広くも、やや狭くも動かせる状態に、更に、必要に応じてその軸回りに回動可能な状態に支持することを意味する。
【００１４】
次に、壁開口から引き出した一対の継手出口側が後方即ち壁体裏面側方向に逃げないようにするため、壁体表面側に後方移動規制部材を設けて、継手出口側の後方への移動を規制した。なお、これにより、壁裏当て材への保持と合せて前後２箇所で保持することになり、一対の継手出口側の平行度と壁体表面に対する垂直度が向上し、次に述べる水栓取付座の着脱が容易になるという効果もある。
【００１５】
次に、一対の継手の平行度と壁体表面に対する垂直度を更に向上させることにより、次に述べる継手出口側と水栓連結管との連結をより容易にすると共に、混合水栓本体を簡便かつ強固に取付固定するため、継手出口側を収納、保持する水栓取付座を設けて、壁体表面側に取付固定した。
【００１６】
混合水栓本体を、水密的にも機械的にも簡便かつ確実、強固に取付固定するため、継手出口側と混合水栓の水栓本体入口側とを水密的に連結する水栓連結管と、混合水栓本体を機械的に取付固定する水栓固定部材を設けた。なお、故障時の対応、及び機能や意匠等の向上のための混合水栓本体の交換を容易ならしめるため、混合水栓本体は着脱自在とした。
【００１７】
また、簡単な構造にして、製造及び施工を容易にすることにより、安価に、継手出口側の後方への移動を規制する手段を得るため、後方移動規制部材を、壁体表面側に当接し得る外形と継手出口側を挿通可能な継手挿通口とを有する継手プレートと、止め輪とから構成し、継手挿通口を継手出口側に嵌め合わせて、略円筒状の継手出口側の後方に形成した円周方向の凹溝を継手プレートの前方即ち壁体表面側方向に露出せしめ、この凹溝に止め輪を挿入係止することにより、継手出口側を、その軸回りに回動可能で、かつ、後方に移動不能に保持した。なお、回動可能に保持するのは、配管取出方向の自由度を確保するとともに、発明の実施の形態で詳しく述べる通り、配管の反発力を緩和して、施工性の向上を図るためである。又、壁体表面に当接し得るとは、壁体表面に直接当接するものは勿論、他の部材等を挟んで、壁体表面に間接的に当接するものをも含み、略円筒状とは、断面が均一径の円筒は勿論、例えば、円筒の内面及び／又は外面に任意方向の凹凸や前後方向のテーパを設けたもの等をも含むことを意味する。
【００１８】
また、容易に施工できるようにして施工コストの低減を図るため、水栓取付座を、継手出口側を挿入可能な継手保持穴を有する水栓取付座本体と、継手保持穴の前方にあって継手出口側の挿通が不能でかつ水栓連結管の挿通が可能な連結管挿通穴を有する抜け止めと、水栓取付座本体の後方外周にあって壁体表面側に当接し得るフランジとから構成して、継手保持穴を継手出口側に嵌め合わせてから、水栓取付座を壁体に固定することにより、継手出口側を、その軸回りに回動可能で、かつ、後方以外の方向に略移動不能に保持した。なお、略移動不能とは、想定する各種の寸法誤差等を吸収するための多少の遊びを許容することを意味する。
【００１９】
また、混合水栓本体を取付固定する水栓取付座の取付強度を確保し、かつ、水栓取付座の小型化と、それに伴うコスト低減、意匠性の向上を図り、メンテナンスをも容易とするため、水栓取付座を、壁体表面側から、壁開口を通し壁体を挟んで、壁体裏面側に設けた（継手出口側の保持のみならず、荷重分散を図る役目をも担う）壁裏当て材に連結固定した。なお、壁開口を通して連結固定するとは、壁開口の内、貫通継手が占有する領域を除いた部分を利用して、ねじ等を使ってお互いをつなぎ合わせて固定する、という意味であり、これによって、壁開口を拡大したり、連結固定するための穴を新たに開けたりする必要がなく、壁開口の外側で壁体に取付固定する場合に比べて、大幅な小型化が可能となる訳である。
【００２０】
また、継手出口側、水栓取付座、混合水栓本体相互の取合に、壁パネルの厚さ種類やその誤差の吸収を考慮する必要をなくして、構造の単純化と小型化を可能ならしめ、製品コストの低減を図るため、継手出口側及び水栓取付座の前後位置を、壁体表面側を基準に位置決めするようにした。混合水栓本体は水栓取付座に取付固定するため、継手出口側及び水栓取付座の前後位置を、壁体表面側を基準に位置決めすれば、混合水栓本体も同じ基準で位置決めすることになるので、継手出口側、水栓取付座、混合水栓本体の三者の前後の位置関係が常に一定になる訳である。
【００２１】
また、製品に要求される寸法精度を低く抑えながら、施工を容易なものとして、漏水の可能性と、製品コスト及び施工コストの低減を図るため、一対の継手出口側の間隔と、水栓本体入口側の水側及び湯側の間隔との寸法誤差を吸収する、芯間調整手段を設けた。
【００２２】
また、簡単な構造にして、製造及び施工を容易にすることにより、安価に、芯間調整機能を得るため、芯間調整手段を、水栓連結管と水栓本体入口側とを固定する連結管固定材と水栓連結管との間、及び／又は、水栓取付座の継手保持穴と継手出口側との間に、所定の遊びを設けた。なお、連結管固定材とは、袋ナットや押え板等のことであり、所定の遊びとは、一対の継手出口側の間隔と、水栓本体入口側の水側及び湯側の間隔との、想定する各種寸法誤差等を吸収するに必要十分な逃げ寸法のことを指す。
【００２３】
以下、本発明の実施の形態を、図面を参照しつつ更に詳説する。
【００２４】
図１は、本発明を浴室ユニットの壁パネルに取付ける１穴式混合水栓に適用した第１実施例の断面分解斜視図、図２は第１実施例の正面図、図３は第１実施例の要部断面斜視図、図４は第１実施例の要部縦断面図で、１は配管、２は継手（貫通継手）、３は壁裏当て材、４は壁パネル（壁体）、５は後方移動規制部材、６は水栓取付座、７は水栓連結固定部材（水栓連結管と水栓固定部材）、８は混合水栓本体である。
【００２５】
本実施例の標準的な施工要領を説明しながら、各部の構成や、それぞれの施工段階における本実施例の効果について説明する。なお、施工順序その他の要領は、必ずしもこの通りでなくとも良い。
【００２６】
▲１▼一対、即ち水側及び湯側の配管１を敷設し、浴室ユニットの防水床パン（図示せず）等に仮固定し、配管１に継手２の継手入口側２１に形成された入口側接続部２１１を接続して、一対の継手２の高さが略揃うように位置の粗調整を行う。
【００２７】
本実施例では、配管１は可撓性樹脂配管で、入口側接続部２１１はワンタッチ接続式の接続継手となっているので、配管１を挿し込むだけで確実に接続、固定され、漏水のおそれもない。又、入口側接続部２１１は自由回転式の接続継手ともなっているため、配管１の曲げ癖や捩じれがあっても接続が容易で、継手出口側２２があらぬ方向を向いても、修正に手間取ることもない。
【００２８】
▲２▼壁裏当て材本体３１とともに壁裏当て材３を構成し、継手出口側２２を壁裏当て材本体３１に保持する役目を担う、壁裏保持材３２に形成された一つの壁裏保持材開口３２１に、一対の継手出口側２２を通し、壁裏保持材３２に形成された継手保持部３２２を、継手出口側２２の後方に形成された凹溝２３に嵌め込む。
【００２９】
本実施例では、壁裏保持材３２は、半硬質樹脂でできているため、変形させて、継手保持部３２２の内法より大きい外径を持つ継手出口側２２を通過させるのは容易である。
【００３０】
▲３▼壁裏当て材本体３１に形成された一つの壁裏当て材開口３１１に一対の継手出口側２２を挿通し、壁裏保持材３２に形成された爪３２３を壁裏当て材開口３１１に挿入係止する。
【００３１】
本実施例では、壁裏保持材３２は半硬質樹脂製である上、爪３２３の前方先端は斜面、その後方は鉤状になっているため、壁裏当て材開口３１１への挿入係止は容易であるが、更に壁裏保持材３２には把持部３２４を形成しているので、この部分を把持することにより、爪３２３を内側に撓ませると、更に容易に挿入係止できる。この簡単な作業で、一対の継手出口側２２は、壁裏当て材３にて、略所定の間隔に保持され緩やかに一体化される。又、継手出口側２２はその軸回りに回動可能に保持される、即ち、継手入口側２１がどの方向を向いていても保持が可能であるので、配管１の曲げ癖や捩じれがあっても、従来のように、配管１の反発力に逆らいつつ継手入口側２１を所定の向きに合せて固定するために苦労する必要はなく、本工程での継手出口側２２の保持作業はきわめて容易である。
【００３２】
▲４▼一対の継手出口側２２の位置を、壁パネル４に開設された一つの壁開口４１の位置に合せた場合より、配管１がやや長目になるように調整して、配管１を浴室ユニットの防水床パン等に本固定し、壁パネル４を建て込み、継手出口側２２を壁開口４１から手前側に引き出す。
【００３３】
前記工程▲３▼で一対の継手出口側２２は緩やかに一体化されているためバラバラになることはなく、又、一対の配管１で支持されるため、お互いに強度を補い合い、曲がりを矯正し合うので、一対の継手２を各１本の配管１で支持する場合に比べて、自立し易く、かつ所定の位置に留まり易いため、位置合わせがやり易い。更に、壁開口４１全体を継手出口側２２が占めるわけではなく適当な空間ができるため、手指を挿入して継手出口側２２を手前側に引き出すのは容易である。本実施例では、継手出口側２２はその軸回りに回動可能に保持されており、しかも配管１が可撓性樹脂配管であるため、配管１をやや長目に調整しておけば、継手出口側２２がその軸回りに回動することにより配管１が容易に撓み、継手出口側２２を壁開口４１の位置に合わせて引込むことは容易である。なお、壁裏当て材本体３１に形成された３個の壁裏当て材突起３１２の外接円は、壁開口４１の内径よりやや小さくしてあるので、各種の誤差があっても確実に壁開口４１内に嵌合でき、混合水栓本体８を所定の位置に正確に取り付けることに寄与する。
【００３４】
▲５▼止め環５２とともに後方移動規制部材５を構成する継手プレート５１の継手挿通穴５１１を、十分に引き出した継手出口側２２の後方に形成された凹溝２３が十分に露出するまで嵌め合わせてから、止め環５２を凹溝２３に挿入係止し、継手出口側２２を後方に押し付ける。
【００３５】
本実施例では、止め環５２は、金属や樹脂等の弾性素材で形成されたワンタッチ取付式のスナップリングとなっているため、凹溝２３への挿入係止は容易である。又、凹溝２３の前後幅が十分に大きいので、壁パネル４の厚さ種類への対応範囲が広く、又、止め環５２を凹溝２３に挿入係止するに十分なだけ継手出口側２２を引き出せる。この簡単な作業で、一対の継手出口側２２は、止め環５２及び継手プレート５１、即ち後方移動規制部材５を介して壁パネル４に押し当てられて、後方への移動を規制されるので、下記工程▲６▼▲７▼▲９▼で、継手２が後方へ逃げるおそれがなくなる。又、継手出口側２２は、上記工程▲３▼と同様、継手入口側２１がどの方向を向いていても保持が可能であるので、上記工程▲４▼で配管１を撓ませることが可能となり、配管１はやや長目になるように大まかに調整すれば良いので、配管１の長さ調整作業と継手出口側２２の保持作業はきわめて容易である。又、本工程で、一対の継手出口側２２の平行度と壁パネル４表面に対する垂直度が増すので、下記工程▲６▼の作業が容易となる。更に、一対の継手出口側２２は、互いに略必要最小限の間隔で配置されるため、混合水栓の小型化に寄与する。
【００３６】
▲６▼水栓取付座６の取付座本体６１の内部に形成された一対の継手保持穴６２と一対の継手出口側２２とを嵌め合せてから、座固定ねじ６３を、座固定穴６４、座固定ねじ挿通穴５１３、壁開口４１を通して、壁裏当て材本体３１に形成した座固定ねじ穴３１３に螺合して、水栓取付座６を、簡単には動かないが力を入れれば回転できる程度に、仮固定する。
【００３７】
この作業により、一対の継手出口側２２は、抜け止め６５によって前方への移動を、継手保持穴６２によって前方及び後方以外の方向への移動を規制されると共に、平行度と壁パネル４表面に対する垂直度を更に増して、下記工程▲７▼▲９▼での水栓連結管７１の挿入が容易になる。本実施例では、上記工程▲３▼▲５▼と同様、継手出口側２２はその軸回りに回動可能であるので、継手入口側２１の向きに関係なく、本工程での保持作業もきわめて容易である。又、水栓取付座６と壁裏当て材本体３１とは、壁開口４１の内、継手出口側２２が占有する領域を除いた部分を利用してねじ固定されるので、壁開口４１の外側で壁パネル４に取付固定する場合に比べて、大幅な小型化が可能となり、意匠の向上と製品コストの低減ができる。更に、継手プレート５１に形成された３個の継手プレート突起５１２の外接円は、壁裏当て材突起３１２と同様、壁開口４１の内径よりやや小さくしてあるので、各種の誤差があっても確実に壁開口４１内に嵌合でき、混合水栓本体８を所定の位置に正確に取り付けることに寄与する。又、壁裏当て材突起３１２と継手プレート突起５１２の位置は、互いに重ならないように配置してあるので、壁パネル４の厚さが薄い場合でも、双方の突起が衝突して、壁を十分に締め付け固定できなくなるおそれがない。
【００３８】
▲７▼袋ナット（水栓固定部材）７２とともに水栓連結固定部材７を構成する、混合水栓本体８の水栓本体入口側８１に押え板７１１によって取付固定された一対の水栓連結管７１を、水栓取付座６に設けられた一対の連結管挿通穴６６を通して、継手出口側２２に設けられた連結管接続穴２２１に十分に挿入してから、混合水栓本体８を左右に回転して、取付角度の調整を行う。
【００３９】
本実施例では、水栓連結管７１の後方端外面、及び連結管接続穴２２１の前方端内面は面取りされており、上記工程▲６▼で保持された継手出口側２２と継手保持穴６２との間には、想定する各種寸法誤差を吸収するに必要十分な所定の遊びが設けられているため、一対の継手出口側２２が、一対の水栓連結管７１の間隔に合せて移動する、即ち、自らの間隔を自動調整するので、挿入は容易である。又、上記工程▲６▼で、壁裏当て材本体３１と水栓取付座６とは回転可能な状態となっているため、取付角度の調整も容易である。
【００４０】
▲８▼混合水栓本体８を一旦取り外し、座固定ねじ６３を十分に締め付ける。
【００４１】
この作業により、水栓取付座６は、取付座本体６１の後方外周部に形成されたフランジ６７と、荷重分散の役目を担う壁裏当て材本体３１とで壁パネル４を挟み込んで、強固に取付固定される。なお、継手出口側２２は、止め環５２、継手プレート５１を介して壁パネル４の表面側に押し付けられるので、壁パネル４の表面側を基準にして位置決めされることになり、かつ、水栓取付座６も壁パネル４の表面側を基準に位置決めされるので、継手出口側２２、水栓取付座６、混合水栓本体８相互の取合に、壁パネル４の厚さ種類やその誤差の吸収を考慮する必要がなく、従って、構造の単純化と小型化が可能になって、製品コストを低減できる。又、本実施例では、フランジ６７の裏面には、パッキン６８が貼り付けてあるので、この簡単な作業で、水栓取付部の水密性を確保でき、かつ、パッキン６８の弾性及び摩擦抵抗によって、取付部が緩んだり回転したりすることを防止できる。
【００４２】
▲９▼再び、混合水栓本体８に固定された水栓連結管７１を、連結管接続穴２２１に挿入し、混合水栓本体８を後方に押し付けながら、混合水栓本体８の水栓本体入口側８１に、押え板７１１によって保持された袋ナット７２の雌ねじ７２１を、水栓取付座６に形成された水栓固定ねじ６９に螺合し、十分に締め付けると完成である。
【００４３】
本実施例では、連結管接続穴２２１の内部にはＯリング２２２が設けられているため、この工具不要の簡単な作業で、継手出口側２２、水栓連結管７１、混合水栓本体８が水密的に連結され、かつ、混合水栓本体８は、袋ナット７２を介して、水栓取付座６に強固に取付固定される。又、水栓取付座６は、上記工程▲８▼で、壁パネル４に強固に取付固定されているので、混合水栓８も、壁パネル４に強固に取付固定されることになる。更に、水栓連結管７１を、連結管接続穴２２１に挿入すると、継手出口側２２に内蔵された開閉弁２２３が開き、引き抜くと開閉弁２２３が閉じるようになっているので、元栓を閉めないでも混合水栓本体８を着脱でき、メンテナンス時等の施工手間を低減できる。又、元栓を閉めないで、誤って混合水栓本体８を取り外した場合にも、湯水が吹出して事故に発展することを防止できる。
【００４４】
以上の通り、本実施例の混合水栓の取付構造では、配管接続を含む混合水栓の取付作業が、壁パネル４建て込み前の作業及び壁パネル４建て込み後の壁パネル４表面側からの作業で、全て可能であるので、壁パネル４の裏面側に作業者が回れる空間や通路を設けるとか、壁パネル４に作業用の開口を設ける必要がなく、各作業もきわめて容易で、かつ確実に取付固定でき、しかも、小型で簡単な構成、形状であるので、製造性、施工性、意匠、清掃性、コストの全ての面で、課題を解決できる。又、意匠や機能向上のために、混合水栓本体８を取り替えることも、きわめて容易である。

【００４６】
本実施例と第１実施例との主な違いは、次の通りであであり、他の部分は、基本的に第１実施例と同一であるので、同一機能かつ同一名称の部分には同じ符号を付して説明する。
【００４７】
１）第１実施例の１穴式に対して、本実施例は２穴式であること。
【００４８】
２）第１実施例では、壁裏保持材を壁裏当て材本体の後方に配置したが、本実施例では、壁裏当て材本体の前方に配置したこと。
【００４９】
３）第１実施例では、連結管固定材を押え板とし、水栓連結管及び水栓固定部材の混合水栓本体への取付を工場組立としたが、本実施例では、連結管固定材を第１袋ナットとし、水栓連結管及び水栓固定部材の取付を施工現場での組立てとしたこと。
【００５０】
４）第１実施例では、芯間調整手段を、水栓取付座の継手保持穴と継手出口側との間に所定の遊びを設けたものとしたが、本実施例では、水栓連結管と水栓本体入口側とを固定する第１袋ナット（連結管固定材）と水栓連結管との間に所定の遊びを設けたものとしたこと。
【００５１】
第１実施例の場合と同様、本実施例の標準的な施工要領を説明しながら、各部の構成や、それぞれの施工段階における本実施例の効果について説明する。なお、施工順序その他の要領は、第１実施例の場合と同様、必ずしもこの通りでなくとも良い。
【００５２】
▲１▼一対の配管１を敷設し、浴室ユニットの防水床パン（図示せず）等に仮固定し、配管１に継手２の継手入口側２１に形成された入口側接続部２１１を接続して、一対の継手２の高さが略揃うように位置の粗調整を行う。
【００５３】
本実施例では、配管１は可撓性樹脂配管で、入口側接続部２１１はワンタッチ接続式の接続継手となっているので、配管１を挿し込むだけで確実に接続、固定され、漏水のおそれもない。又、入口側接続部２１１は自由回転式の接続継手ともなっているため、配管１の曲げ癖や捩じれがあっても接続が容易で、継手出口側２２があらぬ方向を向いても、修正に手間取ることもない。
【００５４】
▲２▼壁裏当て材本体３１に形成された一対の壁裏当て材開口３１１に、一対の継手出口側２２を挿通した後、壁裏当て材本体３１とともに壁裏当て材３を構成し継手出口側２２を壁裏当て材本体３１に保持する役目を担う一対の壁裏保持材３２に形成された壁裏保持材開口３２１を、一対の継手出口側２２に嵌め合わせ、壁裏保持材３２に形成された継手保持部３２２を、継手出口側２２の後方に形成された凹溝２３に嵌め込む。
【００５５】
本実施例では、壁裏保持材３２は、半硬質樹脂でできているため、変形させて、継手保持部３２２の内法より大きい外径を持つ継手出口側２２を通過させるのは容易である。
【００５６】
▲３▼壁裏保持材３２に形成された爪３２３を壁裏当て材開口３１１に挿入係止する。
【００５７】
本実施例では、壁裏保持材３２は半硬質樹脂製である上、爪３２３の後方先端は斜面、その前方は鉤状になっているため、壁裏当て材開口３１１への挿入係止は容易であるが、更に壁裏保持材３２には把持部３２４を形成しているので、この部分を把持することにより、爪３２３を内側に撓ませると、更に容易に挿入係止できる。この簡単な作業で、一対の継手出口側２２は、壁裏当て材３にて、略所定の間隔に保持され緩やかに一体化される。又、継手出口側２２はその軸回りに回動可能に保持される、即ち、継手入口側２１がどの方向を向いていても保持が可能であるので、配管１の曲げ癖や捩じれがあっても、従来のように、配管の反発力に逆らいつつ継手入口側２１を所定の向きに合せて固定するために苦労する必要はなく、本工程での継手出口側２２の保持作業はきわめて容易である。
【００５８】
▲４▼一対の継手出口側２２の位置を、壁パネル４に開設された一対の壁開口４１の位置に合せた場合より、配管１がやや長目になるように調整して、配管１を浴室ユニットの防水床パン等に本固定し、壁パネル４を建て込み、継手出口側２２を壁開口４１から手前側に引き出す。
【００５９】
前記工程▲３▼で一対の継手出口側２２は緩やかに一体化されているためバラバラになることはなく、又、一対の配管１で支持されるため、お互いに強度を補い合い、曲がりを矯正し合うので、一対の継手２を各１本の配管１で支持する場合に比べて、自立し易く、かつ所定の位置に留まり易いため、位置合わせがやり易い。更に、壁開口４１全体を継手出口側２２が占めるわけではなく適当な空間ができるため、手指を挿入して継手出口側２２を手前側に引き出すのは容易である。本実施例では、継手出口側２２はその軸回りに回動可能に保持されており、しかも配管１が可撓性樹脂配管であるため、配管１をやや長目に調整しておけば、継手出口側２２がその軸回りに回動することにより配管１が容易に撓み、継手出口側２２を壁開口４１の位置に合わせて引込むことは容易である。
【００６０】
▲５▼止め環５２とともに後方移動規制部材５を構成する継手プレート５１の継手挿通穴５１１を、十分に引き出した継手出口側２２の後方に形成された凹溝２３が十分に露出するまで嵌め合わせてから、止め環５２を凹溝２３に挿入係止し、継手出口側２２を後方に押し付ける。
【００６１】
本実施例では、止め環５２は、金属や樹脂等の弾性素材で形成されたワンタッチ取付式のスナップリングとなっているため、凹溝２３への挿入係止は容易である。又、凹溝２３の前後幅が十分に大きいので、壁パネル４の厚さ種類への対応範囲が広く、又、止め環５２を凹溝２３に挿入係止するに十分なだけ継手出口側２２を引き出せる。この簡単な作業で、一対の継手出口側２２は、止め環５２及び継手プレート５１、即ち後方移動規制部材５を介して壁パネル４に押し当てられて、後方への移動を規制されるので、下記工程▲６▼▲７▼▲８▼で、継手２が後方へ逃げるおそれがなくなる。又、継手出口側２２は、上記工程▲３▼と同様、継手入口側２１がどの方向を向いていても保持が可能であるので、上記工程▲４▼で配管１を撓ませることが可能となり、配管１はやや長目になるように大まかに調整すれば良いので、配管１の長さ調整作業と継手出口側２２の保持作業はきわめて容易である。又、本工程で、継手出口側２２の平行度と壁パネル４表面に対する垂直度が増すので、下記工程▲６▼の作業が容易となる。又、継手プレート５１に形成された４個の継手プレート突起５１２の外接円は、壁開口４１の内径よりやや小さくしてあるので、各種の誤差があっても確実に壁開口４１内に嵌合でき、混合水栓本体８を所定の位置に正確に取り付けることに寄与する。
【００６２】
▲６▼水栓取付座６の取付座本体６１の内部に形成された一対の継手保持穴６２と一対の継手出口側２２とを嵌め合せてから、座固定ねじ６３を、座固定穴６４、座固定ねじ挿通穴５１３、壁開口４１を通して、壁裏当て材本体３１に形成した座固定ねじ穴３１３に螺合し十分に締め付けて、水栓取付座６を取付固定する。
【００６３】
この作業により、一対の継手出口側２２は、抜け止め６５によって前方への移動を、継手保持穴６２によって前方及び後方以外の方向への移動を規制されると共に、平行度と壁パネル４表面に対する垂直度を更に増して、下記工程▲７▼での水栓連結管７１の挿入が容易になる。又、継手出口側２２は、止め環５２、継手プレート５１を介して壁パネル４の表面側に押し付けられるので、壁パネル４の表面側を基準にして位置決めされることになり、かつ、水栓取付座６も壁パネル４の表面側を基準に位置決めされるので、継手出口側２２、水栓取付座６、混合水栓本体８相互の取合に、壁パネル４の厚さ種類やその誤差の吸収を考慮する必要がなく、従って、構造の単純化と小型化が可能になって、製品コストを低減できる。本実施例では、上記工程▲３▼▲５▼と同様、継手出口側２２はその軸回りに回動可能であるので、継手入口側２１の向きに関係なく、本工程での継手出口側２２の保持作業もきわめて容易である。又、水栓取付座６は、取付座本体６１の後方外周部に形成されたフランジ６７と、荷重分散の役目を担う壁裏当て材本体３１とで壁パネル４を挟み込むことにより、強固に取付固定される。又、フランジ６７の裏面には、パッキン６８が貼り付けてあるので、この簡単な作業で、水栓取付部の水密性を確保でき、かつ、パッキン６８の弾性及び摩擦抵抗によって、取付部が緩んだり回転したりすることを防止できる。
【００６４】
▲７▼水栓連結固定部材７は、水栓連結管７１と、前方に向けて開口した第１袋ナット（連結管固定材）７１２と、後方に向けて開口した第２袋ナット（水栓固定部材）７３を備えているが、その第１袋ナット７１２を、間にパッキン７１４を挟んで、混合水栓本体８の水栓本体入口側８１の外周に形成した連結管固定ねじ８２に、水栓連結管７１が、第１袋ナット７１２との間に設けられた遊びの範囲で自由に移動できる程度に、軽く螺合した後、水栓連結管７１を、水栓取付座６に設けられた連結管挿通穴６６を通して、継手出口側２２に設けられた連結管接続穴２２１に挿入する。
【００６５】
本実施例では、水栓連結管７１の後方端外面、及び連結管接続穴２２１の前方端内面は面取りされており、第１袋ナット７１２と水栓連結管７１との間には、想定する各種寸法誤差を吸収するに必要十分な所定の遊びが設けられているため、一対の水栓連結管７１が、一対の継手出口側２２（正確には連結管接続穴２２１）の間隔に合せて移動する、即ち、自らの間隔を自動調整するので、挿入は容易である。
【００６６】
▲８▼混合水栓本体８を後方に押し付けながら、第２袋ナット７３を、取付座本体６１の外周に形成した水栓固定ねじ６９に螺合して十分に締め付けた後、第１袋ナット７１２を十分に締め付けると完成である。
【００６７】
本実施例では、連結管接続穴２２１の内部にはＯリング２２２が設けられているため、この簡単な作業で、継手出口側２２、水栓連結管７１、混合水栓本体８が水密的に連結され、かつ、混合水栓本体８は、第２袋ナット７３を介して、水栓取付座６に強固に取付固定される。水栓取付座６は、上記工程▲６▼で、壁パネル４に強固に取付固定されているので、混合水栓本体８も、壁パネル４に強固に取付固定されることになる。又、水栓連結管７１を、連結管接続穴２２１に挿入すると、継手出口側２２に内蔵された開閉弁２２３が開き、引き抜くと開閉弁２２３が閉じるようになっているので、元栓を閉めないでも混合水栓本体８を着脱でき、メンテナンス時等の施工手間を低減できる。更に、元栓を閉めないで、誤って混合水栓本体８を取り外した場合にも、湯水が吹出して事故に発展することを防止できる。
【００６８】
以上の通り、本実施例の混合水栓の取付構造では、第１実施例と同様、配管接続を含む混合水栓の取付作業が、壁パネル４建て込み前の作業及び壁パネル４建て込み後の壁パネル４表面側からの作業で、全て可能であるので、壁パネル４の裏面側に作業者が回れる空間や通路を設けるとか、壁パネル４に作業用の開口を設ける必要がなく、各作業もきわめて容易で、かつ確実に取付固定でき、しかも、小型で簡単な構成、形状であるので、製造性、施工性、意匠、清掃性、コストの全ての面で、課題を解決できる。又、意匠や機能向上のために、混合水栓本体８を取り替えることも、きわめて容易である。
【００６９】
なお、芯間調整手段を、１穴式の第１実施例では、継手出口側２２と継手保持穴６２との間に設けた所定の遊びとし、２穴式の第２実施例では、第１袋ナット７１２と水栓連結管７１との間に設けた所定の遊びとしたが、第１実施例を一部変更して、押え板７１１と水栓連結管７１との間に所定の遊びを設けることも、第２実施例を一部変更して、継手出口側２２と継手保持穴６２との間に所定の遊びを設けることも可能である。
【００７０】

【発明の効果】
本発明は上記構成により次の効果を発揮する。
【００７９】
請求項１記載の混合水栓の取付構造では、壁体に壁開口を開設し、前記壁体の裏面側に敷設された水側及び湯側配管を、前記壁開口を貫通する一対の貫通継手へ接続し、前記貫通継手に混合水栓を接続する混合水栓の取付構造において、前記壁体の裏面側で、変形により前記貫通継手の出口側を挿入、係止する壁裏当て材にて前記継手出口側を保持すると共に、前記壁体の表面側には、前記継手出口側を収納する水栓取付座を位置させ前記壁裏当て材に連結固定し、さらに前記貫通継手の前記壁体の裏面側への移動を規制する後方移動規制部材を設け、前記継手出口側と前記混合水栓の本体入口を水栓連結管にて連結し、前記混合水栓本体を前記水栓取付座に取付固定した。したがって、水栓取付座と壁裏当て材とで壁体を挟み込んで強固に取付固定されると共に、貫通継手は前後２箇所で保持されることになり、一対の継手の平行度と壁体表面に対する垂直度が向上し、水栓取付座の脱着が容易になる。また、一対の継手出口側は、壁裏当て材で一体化することができる。すなわち、分離独立した一対の継手出口側を壁開口から同時に引き出せ、施工が容易になり、施工コストの低減を図ることができる。
【００８４】
また、請求項２記載の混合水栓の取付構造では、前記壁裏当て材が、ともに開口を有する壁裏保持材と壁裏当て材本体からなり、前記壁裏保持材の変形により前記継手出口側を前記壁裏保持材の開口に挿入、係止すると共に、前記壁裏保持材を前記壁裏当て材本体の開口に挿入、係止し、前記水栓取付座は前記壁裏当て材本体と連結固定した。したがって、壁裏保持材を半硬質樹脂で作成し、その変形により継手出口側を壁裏保持材の開口に挿入、係止させることができ、継手出口側の保持作業はきわめて容易となる。
【００８５】
また、請求項３記載の混合水栓の取付構造では、前記後方移動規制部材が、前記壁体の表面側に当接する継手プレートと止め輪からなり、前記継手プレートに設けた継手挿通口に前記継手出口側を嵌め合わせ、前記継手出口側の外周に形成した凹溝を継手プレートの前方即ち前記壁体の表面側方向に露出させ、前記凹溝に前記止め輪を挿入、係止することにより、前記継手出口側をその軸回りに回動可能で、前記壁体の裏面側へ移動不能に保持した。したがって、いずれの部材も簡単な構造、形状であり、製造及び施工が容易な、従って安価な、継手出口側の後方への移動を規制する手段を得ることができると共に、配管に曲げ癖や捩れがあった場合でも、継手出口側の保持作業は容易となる。
【００８６】
また、請求項４記載の混合水栓の取付構造では、前記水栓取付座が、前記継手出口側を挿入可能な継手保持穴を有する水栓取付座本体と、前記継手保持穴の前方にあって前記継手出口側の挿通が不能で、かつ前記水栓連結管の挿通が可能な連結管挿通穴を有する抜け止めと、前記水栓取付座本体の外周にあって壁体表面側に当接するフランジからなり、前記継手保持穴に前記継手出口側を巌め合わせて収納することにより、前記継手出口側を、その軸回りに回動可能で、後方以外の方向に略移動不能に保持した。したがって、施工が容易で、施工コストの低減を図ることができる。
【００８７】
また、請求項５記載の混合水栓の取付構造では、前記水栓取付座を、前記壁開口を通して前記壁裏当て材に連結固定した。したがって、壁開口の内、継手出口側が占有する領域を除いた部分を利用してねじ等により固定されるので、連結固定するための穴を新たに壁体に開ける必要がなく、加重を分散させることができると共に、混合水栓本体を取付固定する水栓取付座の取付け強度を確保でき、かつ、水栓取付座の小型化と、それに伴うコスト低減、意匠の向上が図れ、メンテナンスも容易になる。
【００８８】
また、請求項６記載の混合水栓の取付構造では、前記継手出口側及び前記水栓取付座の前後位置を、前記壁体の表面側を基準に位置決めすることとした。したがって、継手出口側、水栓取付座、混合水栓本体相互の取合に、壁パネルの厚さ種類やその誤差の吸収を考慮する必要がなく、構造の単純化と小型化が可能になり、製品コストの低減をはかることができる。
【００８９】
また、請求項７記載の混合水栓の取付構造では、水側及び湯側の貫通継手の出口側間の間隔と、前記混合水栓本体の水側及び湯側の入口間の間隔との寸法誤差を吸収する、芯間調整手段を設けた。したがって、継手出口側と混合水栓入口側との取合で、寸法的な遊びが取り易くなり、製品に要求される寸法精度を低く抑えながら、施工が容易になり、漏水の可能性と、製品コスト及び施工コストの低減を図ることができる。
さらに、請求項８記載の混合水栓の取付構造では、前記芯間調整手段が、前記水栓連結管と前記混合水栓本体入口側を固定する連結管固定材と、前記水栓連結管との間、及び／又は、前記継手保持穴と前記継手出口側との間に、所定の遊びを設けた。したがって、構造が簡単で、製造及び施工が容易になり、安価に、芯間調整機能を得ることができる。

BACKGROUND OF THE INVENTION
The present invention is an exposed mixed water faucet that is attached to a wall and has a functional part exposed (hereinafter abbreviated unless it is particularly necessary to clearly indicate an exposed type or to distinguish between a 2-hole type and a 1-hole type described later). And a mixing faucet). In addition, a wall body here refers to the whole thing which has a surface for attaching a mixing faucet, such as a wall, a counter, and a bathtub, and the surface which installs a mixing faucet is any of a vertical surface, a horizontal surface, and a slope. Regardless of whether or not the mixed faucet is a through joint that connects the pipe on the back side of the wall and the mixed faucet on the wall surface (hereinafter, it is necessary to quote a claim or to distinguish between the water side and the hot water side) It may be a two-hole type in which a wall opening through which water passes is separately provided on the water side and the hot water side, or a one-hole type shared by one wall opening. Absent.
[0002]
[Prior art]
A) Conventionally, a joint mounting structure provided on a wall body for mounting and fixing a single faucet or a two-hole exposed mixed water faucet on the wall body is disclosed in JP-A 63-142134 "Temporary fixing structure", Japanese Patent Laid-Open No. 9-152058, "Fitting structure for fitting in joint storage box", Japanese Patent Laid-Open No. 10-72852, "Water faucet mounting device", Japanese Patent Laid-Open No. 3-69734, "Relay connection for fluid piping" However, since the faucet is attached and fixed to the wall body via the joint, the joint is also firmly attached and fixed to the wall body and the wall supporting materials. .
[0003]
B) On the other hand, in order to attach and fix the mixed faucet body to a pair of water side and hot water side joints attached and fixed to a wall or the like, the gaps between the joint cores and the cores on the inlet side of the mixed water faucet body are matched. Therefore, as shown in Fig. 9, a pair of crank-shaped, such as "Wall thermostat hot / cold water faucet" in "Appendix 8 (reference) faucet shape" of JIS B2061 "Water faucet" The joint and the mixed water faucet body 800 are connected via the bent connecting part 900.
[0004]
C) Also, in order to eliminate the crank-shaped parts, as in JP-A-9-3993 “Water faucet fitting”, in order to obtain an accurate distance, a joint is connected with a flange, or JP-A-8-184082 “hot water” is used. Some have a holding portion that can adjust the distance between joints, such as a “fixing structure of a faucet elbow for a mixed faucet and a connection structure of mounting legs”.
D) Further, in the case of a single-hole type mixing faucet, as disclosed in JP-A-1-299927 “Hot-water supply device to mixing faucet” and JP-A-11-36392 “Connecting structure of hot-water mixing faucet” There is a type that connects a water faucet and a hot water side integrated with a mixing faucet body.
[0005]
[Problems to be solved by the invention]
In the joint mounting structure of A), the joint is firmly fixed to the wall and the wall support material, so the distance between the pair of joints is completely fixed, and the joint mounting and fixing work is also performed at the construction site. Therefore, it is difficult to obtain accuracy, and therefore, there is a high possibility that the mixing faucet body cannot be mounted and fixed because it does not coincide with the interval at the inlet side of the mixing faucet body.
[0006]
For this reason, as shown in B), the coupling and the mixing faucet body 800 are connected via the connecting part 900 bent in a crank shape. However, the adjustment work not only requires considerable skill. There is a great possibility of water leakage, and there is a pair of connecting parts 900 between the wall body and the mixing faucet main body 800, and the shape is complicated, so that there are problems in terms of cost, design, and cleanability.
[0007]
In order to solve this problem, C) has been proposed. However, the former requires high dimensional accuracy for both the joint interval and the interval at the inlet side of the mixing faucet body. There is a problem of inviting. In the latter case, the workability is improved by the ease of adjusting the joint interval from the general A). However, since it cannot be adjusted from the front side of the wall body after the wall construction, the joint spacing is reduced. It is necessary to precisely match the interval on the inlet side of the mixing faucet main body in advance, and if this is forgotten or neglected, there is a possibility that it will be impossible to apply a hand if it cannot be turned to the back side of the wall.
[0008]
In D), since the joint on the water side and the hot water side are integrated, it is difficult to obtain dimensional play in the connection with the inlet side of the mixing faucet body, and high dimensional accuracy is required, making it difficult to manufacture and install. In addition, there is a problem that the cost is increased due to this, and the possibility of water leakage due to poor manufacturing and construction accuracy is high.
[0009]
In any of the above prior arts, since the joint is fixed and fixed so as not to rotate, the degree of freedom in the pipe take-out direction is limited, and the joint is attached due to repulsive force caused by bending or twisting of the pipe. There is also a problem that it is difficult to mount and fix in a predetermined direction, resulting in an increase in construction cost.
[0010]
The present invention has been made to solve the above-mentioned problems, and the object of the present invention is easy to manufacture and install regardless of the one-hole type or the two-hole type, and has good design and cleanability.

[0013]
DETAILED DESCRIPTION OF THE INVENTION
wallA structure for installing a mixing faucet having a wall opening established in the body, a through joint passing through the wall opening, and a mixing faucet body connected to the joint outlet sideThen,When hands are integrated, dimensional play is difficult to achieve at the joint outlet side and mixing faucet inlet side, and high dimensional accuracy is required, making manufacturing and installation difficult, and associated cost increases In order to solve this problem, water-side and hot-water penetration joints are separated and independent from each other. . Furthermore, in order to facilitate construction and reduce construction costs so that a pair of separated joint outlets can be pulled out from the wall opening at the same time, and the joint attached to the pipe is self-supporting and can easily stay in place. A wall backing material was provided on the back side of the wall body, and the pair of joint outlet sides were held at a substantially predetermined interval to be gently integrated. Note that holding at a substantially predetermined interval does not mean fixing it so that it does not move at a predetermined interval, but allows it to move slightly wider or slightly narrower than the predetermined interval, and if necessary, about its axis. It means that it is supported in a rotatable state.
[0014]
Next, the pair of joint outlets pulled out from the wall opening is the rear or wall body.backIn order not to escape in the surface side direction, a rearward movement restricting member is provided on the wall surface side to restrict rearward movement on the joint outlet side. In addition, by this, it will be held at two places in the front and back together with the holding to the wall backing material, the parallelism on the pair outlet side and the perpendicularity to the wall surface will be improved. There is also an effect that the seat can be easily attached and detached.
[0015]
Next, by further improving the parallelism of the pair of joints and the perpendicularity to the wall surface, it is easier to connect the outlet side of the joint described below and the faucet connecting pipe, and the mixing faucet body is simplified. In order to firmly mount and fix, a faucet mounting seat for storing and holding the joint outlet side was provided and fixed to the wall surface side.
[0016]
MixedA faucet connecting pipe for watertightly connecting the joint outlet side and the faucet body inlet side of the mixing faucet in order to easily and securely and securely attach and fix the water faucet body mechanically and mechanically. A faucet fixing member for mechanically attaching and fixing the mixed faucet body was provided. In addition, the mixing faucet body was made detachable in order to facilitate the replacement of the mixing faucet body in order to cope with failure and improve the function and design.
[0017]
Also,In order to obtain a means for regulating the backward movement of the joint outlet side at a low cost by making the structure simple and facilitating manufacture and construction, the outer shape capable of abutting the rear movement restriction member on the wall surface side And a joint plate having a joint insertion port through which the joint outlet side can be inserted, and a retaining ring. A circle formed on the rear side of the substantially cylindrical joint outlet side by fitting the joint insertion port to the joint outlet side. By exposing the groove in the circumferential direction to the front of the joint plate, that is, in the wall surface side direction, and inserting and retaining a retaining ring in the groove, the joint outlet side can be rotated around its axis, and Held immovably backwards. The reason why the rotation is held is to secure the degree of freedom in the pipe take-out direction and, as will be described in detail in the embodiment of the invention, to relieve the repulsive force of the pipe and improve the workability. . The term “can contact the wall surface” includes not only those that directly contact the wall surface but also those that indirectly contact the wall surface with other members in between. In addition to a cylinder having a uniform cross section, it means that, for example, an inner surface and / or an outer surface of the cylinder include irregularities in an arbitrary direction and a taper in the front-rear direction.
[0018]
Also,In order to facilitate installation and reduce the construction cost, the faucet mounting seat has a faucet mounting seat body with a joint holding hole into which the joint outlet side can be inserted, and the joint outlet in front of the joint holding hole. A stopper that has a connecting pipe insertion hole through which the faucet connecting pipe can be inserted, and a flange that is in the rear outer periphery of the faucet mounting seat body and can come into contact with the wall surface side. After fitting the joint holding hole to the joint outlet side, the faucet mounting seat is fixed to the wall body, so that the joint outlet side can be rotated about its axis and substantially in the direction other than the rear. Kept immovable. Note that “substantially immovable” means allowing some play to absorb various dimensional errors and the like.
[0019]
Also,In order to secure the mounting strength of the faucet mounting seat for mounting and fixing the mixed faucet body, and to reduce the size of the faucet mounting seat, reduce the costs associated with it, improve the design, and facilitate maintenance, The faucet mounting seat is provided on the back side of the wall from the wall surface through the wall opening (not only holding the joint outlet side, but also the role of distributing the load) It was connected and fixed to the brazing material. In addition, connecting and fixing through the wall opening means that the part other than the area occupied by the penetration joint in the wall opening is used to connect and fix each other using screws or the like. There is no need to enlarge the wall opening or make a new hole for connecting and fixing, and it is possible to significantly reduce the size compared to mounting and fixing to the wall outside the wall opening. is there.
[0020]
Also,The joint outlet side, faucet mounting seat, mixing faucet body mutual connection eliminates the need to consider the thickness of the wall panel and absorption of its error, making it possible to simplify and miniaturize the structure, In order to reduce the product cost, the front and back positions of the joint outlet side and the faucet mounting seat are positioned based on the wall surface side. Since the mixing faucet body is fixed to the faucet mounting seat, if the front and rear positions of the joint outlet side and faucet mounting seat are positioned relative to the wall surface side, the mixing faucet body should also be positioned based on the same reference. Therefore, the positional relationship between the three sides of the joint outlet side, the faucet mounting seat, and the mixed faucet body is always constant.
[0021]
Also,To keep the dimensional accuracy required for the product low and make the installation easy, the possibility of water leakage and the reduction of the product cost and construction cost. A center-to-core adjusting means for absorbing a dimensional error between the water side and the hot water side is provided.
[0022]
Also,In order to obtain a center-to-core adjustment function at a low cost by making the structure simple and facilitating manufacture and construction, the center-to-core adjustment means is a connection pipe fixing that fixes the faucet connection pipe and the faucet body inlet side. Predetermined play was provided between the material and the faucet connecting pipe and / or between the joint holding hole of the faucet mounting seat and the joint outlet side. The connecting pipe fixing material is a cap nut, a presser plate, etc., and the predetermined play is a distance between a pair of joint outlet side and a water side and hot water side distance on the faucet body inlet side. The clearance dimension necessary and sufficient to absorb various dimensional errors assumed.

FIG. 4 is a longitudinal sectional view of a main part of the first embodiment, 1 is a pipe, 2 is a joint (penetrating joint), 3 is a wall backing material, and 4 is a wall panel (wall body). 5 is a backward movement restricting member, 6 is a faucet mounting seat, 7 is a faucet connection fixing member (a faucet connection pipe and a faucet fixing member), and 8 is a mixing faucet body.
[0025]
While explaining the standard construction procedure of this embodiment, the configuration of each part and the effect of this embodiment at each construction stage will be described. It should be noted that the construction order and other procedures do not necessarily have to be the same.
[0026]
(1) A pair of pipes 1 on the water side and hot water side are laid and temporarily fixed to a waterproof floor pan (not shown) of the bathroom unit, and the inlet formed on the joint inlet side 21 of the joint 2 on the pipe 1 The side connection portion 211 is connected, and the position is roughly adjusted so that the heights of the pair of joints 2 are substantially aligned.
[0027]
In this embodiment, the pipe 1 is a flexible resin pipe, and the inlet side connection portion 211 is a one-touch connection joint. Therefore, the pipe 1 can be securely connected and fixed by simply inserting it, and there is a risk of water leakage. Nor. In addition, since the inlet side connecting portion 211 is also a free-rotating connection joint, it is easy to connect even if the pipe 1 is bent or twisted, and even if the joint outlet side 22 faces away, it can be corrected. There is no time and effort.
[0028]
(2) One wall back formed on the wall back support material 32 which constitutes the wall back material 3 together with the wall back material main body 31 and plays a role of holding the joint outlet side 22 to the wall back material main body 31. The pair of joint outlet sides 22 are passed through the holding member openings 321, and the joint holding portions 322 formed on the wall back holding member 32 are fitted into the concave grooves 23 formed on the rear side of the joint outlet side 22.
[0029]
In the present embodiment, since the wall backing material 32 is made of a semi-rigid resin, it is easy to deform and pass the joint outlet side 22 having an outer diameter larger than the inner diameter of the joint holding portion 322. .
[0030]
(3) A pair of joint outlet sides 22 is inserted into one wall backing material opening 311 formed in the wall backing material main body 31, and the claws 323 formed in the wall backing holding material 32 are inserted into the wall backing material opening 311. Insert and lock into.
[0031]
In this embodiment, the wall backing material 32 is made of a semi-rigid resin, and the front tip of the claw 323 has a slope and the rear thereof has a bowl shape. Therefore, the insertion locking to the wall backing material opening 311 is not performed. Although it is easy, since the grip part 324 is further formed in the wall backing material 32, if the claw 323 is bent inward by gripping this part, it can be inserted and locked more easily. With this simple operation, the pair of joint outlet sides 22 are held at substantially predetermined intervals by the wall backing material 3 and are gently integrated. Further, the joint outlet side 22 is held so as to be rotatable around its axis, that is, the joint inlet side 21 can be held in any direction, so that the pipe 1 is bent or twisted. However, unlike the prior art, there is no need to have trouble in fixing the joint inlet side 21 in a predetermined direction while resisting the repulsive force of the pipe 1, and the holding work of the joint outlet side 22 in this process is extremely easy. It is.
[0032]
(4) Adjust the position of the pair of joint outlet sides 22 to the position of one wall opening 41 established in the wall panel 4 so that the pipe 1 is slightly longer. This is fixed to a waterproof floor pan or the like of the bathroom unit, the wall panel 4 is built, and the joint outlet side 22 is pulled out from the wall opening 41 to the near side.
[0033]
In the step (3), the pair of joint outlet sides 22 are loosely integrated so that they do not fall apart, and since they are supported by the pair of pipes 1, they complement each other and correct bending. Therefore, as compared with the case where each pair of joints 2 is supported by one pipe 1, it is easier to stand up and stay in a predetermined position, so that alignment is easy. Furthermore, since the joint outlet side 22 does not occupy the entire wall opening 41, an appropriate space is created, so that it is easy to insert a finger and pull the joint outlet side 22 toward the front side. In this embodiment, the joint outlet side 22 is held so as to be rotatable about its axis, and the pipe 1 is a flexible resin pipe. Therefore, if the pipe 1 is adjusted slightly longer, As the outlet side 22 rotates about its axis, the pipe 1 can be easily bent, and the joint outlet side 22 can be easily pulled in accordance with the position of the wall opening 41. Since the circumscribed circle of the three wall backing material projections 312 formed on the wall backing material body 31 is slightly smaller than the inner diameter of the wall opening 41, the wall opening is surely ensured even if there are various errors. 41, which contributes to accurately attaching the mixed faucet body 8 to a predetermined position.
[0034]
(5) Fit the joint insertion hole 511 of the joint plate 51 constituting the rear movement restricting member 5 together with the retaining ring 52 until the recessed groove 23 formed on the rear side of the joint outlet side 22 sufficiently pulled out is sufficiently exposed. After that, the retaining ring 52 is inserted and locked in the concave groove 23, and the joint outlet side 22 is pressed backward.
[0035]
In the present embodiment, the retaining ring 52 is a one-touch attachment type snap ring formed of an elastic material such as metal or resin, so that it can be easily inserted into the concave groove 23. Further, since the front and rear width of the groove 23 is sufficiently large, the range corresponding to the thickness type of the wall panel 4 is wide, and the joint outlet side 22 is sufficient to insert and lock the retaining ring 52 into the groove 23. Can be pulled out. In this simple operation, the pair of joint outlet sides 22 are pressed against the wall panel 4 via the retaining ring 52 and the joint plate 51, i.e., the rear movement restricting member 5, and the rearward movement is restricted. In the following processes (6), (7) and (9), there is no possibility that the joint 2 escapes backward. Further, the joint outlet side 22 can be held in any direction of the joint inlet side 21 as in the step (3), so that the pipe 1 can be bent in the step (4). Since the pipe 1 may be roughly adjusted so as to be slightly longer, the length adjustment work of the pipe 1 and the work of holding the joint outlet side 22 are extremely easy. Further, in this step, the parallelism of the pair of joint outlet sides 22 and the perpendicularity to the surface of the wall panel 4 are increased, so that the following step (6) is facilitated. Furthermore, since the pair of joint outlet sides 22 are disposed at a substantially minimum necessary distance from each other, it contributes to the miniaturization of the mixing faucet.
[0036]
(6) After fitting the pair of joint holding holes 62 and the pair of joint outlet sides 22 formed in the mounting seat body 61 of the faucet mounting seat 6, the seat fixing screw 63 is inserted into the seat fixing hole 64, Through the seat fixing screw insertion hole 513 and the wall opening 41, the water faucet mounting seat 6 is screwed into the seat fixing screw hole 313 formed in the wall backing material body 31, and the faucet mounting seat 6 can be rotated if force is applied. Temporarily fix as much as possible.
[0037]
By this operation, the pair of joint outlet sides 22 are restricted from moving forward by the retaining stopper 65 and from being moved in directions other than the front and rear by the joint holding hole 62, and the parallelism with respect to the surface of the wall panel 4. By further increasing the verticality, the faucet connecting pipe 71 can be easily inserted in the following steps (7) and (9). In the present embodiment, the joint outlet side 22 can be rotated around its axis similarly to the above steps (3) and (5). Easy. Further, the faucet mounting seat 6 and the wall backing material main body 31 are screwed using a portion of the wall opening 41 excluding the region occupied by the joint outlet side 22, so that the outside of the wall opening 41 As compared with the case of mounting and fixing to the wall panel 4, the size can be greatly reduced, and the design can be improved and the product cost can be reduced. Further, since the circumscribed circle of the three joint plate projections 512 formed on the joint plate 51 is slightly smaller than the inner diameter of the wall opening 41 as with the wall backing material projection 312, even if there are various errors. It can be surely fitted into the wall opening 41 and contributes to accurately attaching the mixing faucet body 8 to a predetermined position. Further, since the wall backing material projection 312 and the joint plate projection 512 are arranged so as not to overlap each other, even when the wall panel 4 is thin, both projections collide to sufficiently secure the wall. There is no fear that it will not be possible to fasten and fix to.
[0038]
(7) A pair of faucet connection pipes which are fixed to the faucet body inlet side 81 of the mixed faucet body 8 by the presser plate 711 and constitute the faucet connection fixation member 7 together with the cap nut (faucet fixation member) 72. 71 is sufficiently inserted into the connecting pipe connection hole 221 provided on the joint outlet side 22 through the pair of connecting pipe insertion holes 66 provided in the faucet mounting seat 6, and then the mixing faucet body 8 is moved left and right. Rotate to adjust the mounting angle.
[0039]
In this embodiment, the rear end outer surface of the faucet connecting pipe 71 and the front end inner face of the connecting pipe connecting hole 221 are chamfered, and the joint outlet side 22 and the joint holding hole 62 held in the above step (6) Between the pair of joint outlet sides 22 is moved in accordance with the distance between the pair of faucet connecting pipes 71, since predetermined play necessary and sufficient to absorb various dimensional errors assumed is provided between them. That is, since the interval between itself is automatically adjusted, the insertion is easy. In the step (6), the wall backing material body 31 and the faucet mounting seat 6 are in a rotatable state, so that the mounting angle can be easily adjusted.
[0040]
(8) Remove the mixing faucet body 8 and tighten the seat fixing screw 63 sufficiently.
[0041]
By this operation, the faucet mounting seat 6 is firmly held by sandwiching the wall panel 4 between the flange 67 formed on the rear outer peripheral portion of the mounting seat body 61 and the wall backing material body 31 that plays a role of load distribution. Mounted and fixed. Since the joint outlet side 22 is pressed against the surface side of the wall panel 4 via the retaining ring 52 and the joint plate 51, the joint outlet side 22 is positioned with reference to the surface side of the wall panel 4, and the faucet Since the mounting seat 6 is also positioned with respect to the surface side of the wall panel 4, the thickness type of the wall panel 4 and its error can be used for the joint outlet side 22, the faucet mounting seat 6, and the mixed faucet body 8. Therefore, the structure can be simplified and miniaturized, and the product cost can be reduced. In this embodiment, since the packing 68 is attached to the back surface of the flange 67, the watertightness of the faucet mounting portion can be secured by this simple operation, and the elasticity and frictional resistance of the packing 68 can be secured. The mounting portion can be prevented from loosening or rotating.
[0042]
(9) Again, the faucet connecting pipe 71 fixed to the mixing faucet body 8 is inserted into the connecting pipe connecting hole 221, and the faucet body of the mixing faucet body 8 is pressed while pushing the mixing faucet body 8 backward. When the female screw 721 of the cap nut 72 held by the holding plate 711 is screwed onto the inlet side 81 with the water faucet fixing screw 69 formed on the water faucet mounting seat 6, it is completed.
[0043]
In this embodiment, since the O-ring 222 is provided inside the connecting pipe connecting hole 221, the joint outlet side 22, the faucet connecting pipe 71, and the mixing faucet body 8 can be easily operated by this simple tool-free operation. The water faucet body 8 is watertightly connected, and is firmly attached and fixed to the water faucet mounting seat 6 via the cap nut 72. Further, since the faucet mounting seat 6 is firmly attached and fixed to the wall panel 4 in the step (8), the mixed faucet 8 is also firmly attached and fixed to the wall panel 4. Further, when the faucet connecting pipe 71 is inserted into the connecting pipe connecting hole 221, the on-off valve 223 built in the joint outlet side 22 is opened, and when it is pulled out, the on-off valve 223 is closed. However, the mixing faucet main body 8 can be attached and detached, and the construction labor during maintenance can be reduced. Further, even when the mixing faucet body 8 is mistakenly removed without closing the main stopper, it is possible to prevent the hot water from blowing out and developing into an accident.
[0044]
As described above, in the mixing faucet mounting structure of the present embodiment, the mixing faucet mounting operation including pipe connection is performed from the work before the wall panel 4 is built and from the surface side of the wall panel 4 after the wall panel 4 is built. This is all possible, so there is no need to provide a space or a passage for the operator on the back side of the wall panel 4 or to provide an opening for the work on the wall panel 4, and each work is very easy, In addition, since it can be securely mounted and fixed, and has a small and simple configuration and shape, the problems can be solved in all aspects of manufacturability, workability, design, cleanability, and cost. It is also very easy to replace the mixed water faucet body 8 for improving the design and functions.

There is no time and effort.
[0054]
(2) After inserting the pair of joint outlet sides 22 into the pair of wall backing material openings 311 formed in the wall backing material main body 31, the wall backing material 3 and the wall backing material main body 31 constitute the wall backing material 3. The wall backing material openings 321 formed in the pair of wall backing materials 32 that serve to hold the outlet side 22 in the wall backing material main body 31 are fitted to the pair of joint outlet sides 22, and the wall backing material 32 is fitted. The joint holding portion 322 formed in the above is fitted into the groove 23 formed on the rear side of the joint outlet side 22.
[0055]
In the present embodiment, since the wall backing material 32 is made of a semi-rigid resin, it is easy to deform and pass the joint outlet side 22 having an outer diameter larger than the inner diameter of the joint holding portion 322. .
[0056]
(3) The claw 323 formed on the wall backing material 32 is inserted and locked into the wall backing material opening 311.
[0057]
In the present embodiment, the wall backing material 32 is made of a semi-rigid resin, and the rear tip of the claw 323 has a slope and the front thereof has a bowl shape, so that the insertion locking to the wall backing material opening 311 is not Although it is easy, since the grip part 324 is further formed in the wall backing material 32, if the claw 323 is bent inward by gripping this part, it can be inserted and locked more easily. With this simple operation, the pair of joint outlet sides 22 are held at substantially predetermined intervals by the wall backing material 3 and are gently integrated. Further, the joint outlet side 22 is held so as to be rotatable around its axis, that is, the joint inlet side 21 can be held in any direction, so that the pipe 1 is bent or twisted. However, unlike the conventional case, it is not necessary to have a hard time to fix the joint inlet side 21 in a predetermined direction while resisting the repulsive force of the pipe, and the holding work of the joint outlet side 22 in this process is extremely easy. is there.
[0058]
(4) Adjust the position of the pair of joint outlet sides 22 to the position of the pair of wall openings 41 established in the wall panel 4 so that the pipe 1 is slightly longer. This is fixed to a waterproof floor pan or the like of the bathroom unit, the wall panel 4 is built, and the joint outlet side 22 is pulled out from the wall opening 41 to the near side.
[0059]
In the step (3), the pair of joint outlet sides 22 are loosely integrated so that they do not fall apart, and since they are supported by the pair of pipes 1, they complement each other and correct bending. Therefore, as compared with the case where each pair of joints 2 is supported by one pipe 1, it is easier to stand up and stay in a predetermined position, so that alignment is easy. Furthermore, since the joint outlet side 22 does not occupy the entire wall opening 41, an appropriate space is created, so that it is easy to insert a finger and pull the joint outlet side 22 toward the front side. In this embodiment, the joint outlet side 22 is held so as to be rotatable about its axis, and the pipe 1 is a flexible resin pipe. Therefore, if the pipe 1 is adjusted slightly longer, As the outlet side 22 rotates about its axis, the pipe 1 can be easily bent, and the joint outlet side 22 can be easily pulled in accordance with the position of the wall opening 41.

In the present embodiment, the retaining ring 52 is a one-touch attachment type snap ring formed of an elastic material such as metal or resin, so that it can be easily inserted into the concave groove 23. Further, since the front and rear width of the groove 23 is sufficiently large, the range corresponding to the thickness type of the wall panel 4 is wide, and the joint outlet side 22 is sufficient to insert and lock the retaining ring 52 into the groove 23. Can be pulled out. In this simple operation, the pair of joint outlet sides 22 are pressed against the wall panel 4 via the retaining ring 52 and the joint plate 51, i.e., the rear movement restricting member 5, and the rearward movement is restricted. In the following steps (6), (7) and (8), there is no possibility that the joint 2 escapes backward. Further, the joint outlet side 22 can be held in any direction of the joint inlet side 21 as in the step (3), so that the pipe 1 can be bent in the step (4). Since the pipe 1 may be roughly adjusted so as to be slightly longer, the length adjustment work of the pipe 1 and the work of holding the joint outlet side 22 are extremely easy. Further, in this step, the parallelism on the joint outlet side 22 and the perpendicularity to the surface of the wall panel 4 are increased, so that the following step (6) is facilitated. In addition, the circumscribed circle of the four joint plate projections 512 formed on the joint plate 51 is slightly smaller than the inner diameter of the wall opening 41, so that it can be securely fitted into the wall opening 41 even if there are various errors. This contributes to accurately attaching the mixing faucet body 8 to a predetermined position.

In the present embodiment, the rear end outer surface of the faucet connecting pipe 71 and the front end inner face of the connecting pipe connecting hole 221 are chamfered, and it is assumed between the first cap nut 712 and the faucet connecting pipe 71. Since the predetermined play necessary and sufficient to absorb various dimensional errors is provided, the pair of faucet coupling pipes 71 are matched to the interval between the pair of joint outlet sides 22 (more precisely, the coupling pipe connection holes 221). Since it moves, that is, its interval is automatically adjusted, insertion is easy.
[0066]
(8) While pressing the mixing faucet body 8 backward, the second cap nut 73 is screwed into the faucet fixing screw 69 formed on the outer periphery of the mounting seat body 61 and sufficiently tightened, and then the first cap nut When 712 is sufficiently tightened, it is completed.
[0067]
