Description

【発明の属する技術分野】
本発明は、水栓用部品と固定ジョイントとの接続構造に関する。
【０００２】
【従来の技術】
水栓用部品の中には、取付基部（例えば、装置の外郭部や浴室の壁面等）に固定されるものがある。例えば、吐水具（トップシャワー用の吐水具等）の中には、シャワー装置の外郭部に固定されるもの（例えば、特許文献１参照）や、浴室の壁面等に固定されるものがある。かかる固定構造においては、取付基部に固定ジョイントが固定され、水栓用部品が固定ジョイントに固定されることがある。
【０００３】
この固定に際し、水栓用部品の接続部と固定ジョイントの接続部とのうちの一方に他方を挿入すると共に、この挿入によって構成される挿入部分に対し、抜け止め用のネジを装着することがある。
【０００４】
【特許文献１】
特開平１１−３１５５６１号公報（図２、図４）
【０００５】
【発明が解決しようとする課題】
しかし、この接続構造では、ネジが緩んで抜けると、水栓用部品が固定ジョイントから離脱する。よって、ネジの抜けを防止し、水栓用部品と固定ジョイントとの接続構造をより堅固なものとすることが必要とされている。
【０００６】
本発明は、上述の課題を解決するものであり、連結材が挿入部分から抜けることを防止して、水栓用部品が固定ジョイントから抜けることを確実に防止できる、水栓用部品と固定ジョイントとの接続構造を提供することを目的とする。
【０００７】
【課題を解決するための手段】
請求項１の発明の水栓用部品と固定ジョイントとの接続構造（以下、単に「接続構造」と称することがある。）は、所定の水栓用部品の接続部と、所定の固定ジョイントの接続部とのうちの一方に他方を挿入して構成される挿入部分において、抜け止め用の連結材を該挿入部分の外側より、一方の接続部から他方の接続部に至る状態に装着し、両接続部を接続して構成される、水栓用部品と固定ジョイントとの接続構造であって、
カバー材により前記連結材における前記挿入部分からの抜け方向側の端部を覆って前記連結材の該抜け方向への移動を規制することを特徴とする。
【０００８】
請求項１の発明では、連結材が緩む等して挿入部分から抜けようとしても、カバー材が連結材の抜け方向側の端部と当接する。即ち、この当接によって連結材が抜け方向に沿って自由に移動することが規制されるため、この連結材が挿入部分から抜けることが防止され、水栓用部品が固定ジョイントから抜けることが防止される。
【０００９】
ここで、水栓用部品の接続部と固定ジョイントの接続部は、両者とも筒状の接続部（筒状接続部）であってもよいし、外側に配置される接続部が筒状の接続部（筒状接続部）であれば、この接続部に挿入される接続部は中実状（柱状）の接続部であってもよい。また、両接続部のうちの少なくとも一方の内部空間を通水部としたい場合には、例えば、この通水部にしたい接続部を筒状の接続部（筒状接続部）とすればよい。更に、ここに述べる「筒状」は、円筒状に限定されず、三角、四角等の多角形状の横断面を備えた筒形状であってもよい。
【００１０】
カバー材は、「連結材における挿入部分からの抜け方向側の端部（以下、適宜、「当該端部」という。）」と当接しながら、当該端部を覆うものであってもよいが、カバー材と当該端部との間に所定の隙間が設けられてもよい。例えば、連結材が、「カバー材と当該端部との最短距離の方向（挿入部分を構成する接続部が円筒状の場合には半径方向）」に沿って装着される場合には、「連結材の全長（装着方向に沿った全長）」から「連結材における他方の接続部への装着長（装着方向に沿った長さであって、他方の接続部に埋設等されて装着される長さ）」を差し引いた長さを、当該端部とカバー材との隙間（最短距離）よりも大きくすれば、当該端部とカバー材との間に隙間が存在しても、カバー材は連結材の抜け止めを行うことができるからである。
【００１１】
つまり、連結材が緩む等して挿入部分から若干（前記最短距離の分だけ）、抜けようとしても、連結材はカバー材と当接し、それ以上の移動を規制されるため、連結材は依然として挿入部分を構成する両接続部に装着された状態を維持できる。尚、この場合、当該端部と、カバー材との間に「１ｍｍ〜５ｍｍ」の隙間が確保されるとより好適である。この隙間が１ｍｍ未満であると、カバー材の装着の際に、上記端部とカバー材とが当接し、カバー材の装着作業を効率的に行うことができないおそれがある。一方、５ｍｍを超えると、連結材が緩んだとき等に、がたつきが大きくなるおそれがあるからである。
【００１２】
また、連結材は、上述の如く、挿入部分に対して、上記最短距離の方向（両接続部が円筒状の場合等には、両接続部の半径方向）に装着されてもよいが、この最短距離の方向に対して傾斜する（９０度よりも小さな傾斜角）方向に装着されてもよい。即ち、このように、「カバー材と当該端部との最短距離の方向と所定の角度をなす方向に沿ってに装着される場合には、連結材の全長（挿入方向に沿った全長）の「最短距離の方向」への「射影長（所定の角度がα度で、連結材の全長がＬのとき、Ｌ・ＣＯＳαで示す長さ」から「連結材における他方の接続部への装着長」の「最短距離の方向」への「射影長（所定の角度がα度で、装着長がＭのとき、Ｍ・ＣＯＳαで示す長さ」を差し引いた長さを、当該端部とカバー材との隙間（最短距離）よりも大きくすれば、当該端部とカバー材との間に隙間が存在しても、カバー材は連結材の抜け止めを行うことができるからである。
【００１３】
「連結材」としては、「雄ネジ（ビス等）」や「ピン」等のように、挿入部分の外部に露呈する露呈部（例えば、頭部）と、挿入部分に螺合状、螺入状、遊嵌状若しくは圧入状等に装着される埋設部（例えば、軸部）と、を備えるものに限定されず、例えば、埋設部（例えば、軸部）のみによって構成されるもの等であってもよい。より具体的には、「挿入部分を構成する両接続部の部分に、取付孔（内壁面に雌ネジが設けられているか否かを問わない。）が相互に位置合わせ可能な状態に設けられる場合に、この取付孔に螺合状若しくは螺入状に装着される雄ネジ（ビス等）」、「挿入部分に、ねじ込まれながら、この部位に装着される雄ネジ（ビス等）」、「挿入部分を構成する両接続部の部分に、取付孔が相互に位置合わせ可能な状態に設けられる場合に、この取付孔に装着されるピン（遊嵌状に挿入されても、圧入状に挿入されてもよい。）」等を例示できる。
【００１４】
「カバー材」は、水栓用部品と固定ジョイントのうちの一方若しくは両方に保持されてもよいが、水栓用部品及び固定ジョイント以外の部材に保持されてもよい。また、水栓用部品及び固定ジョイントの外側に配置される部品の一部によって「カバー材」を構成することもできる。尚、水栓部品や固定ジョイントの接続部が通水部を構成する場合においても、カバー材が、連結材の抜け方向側の端部を覆うだけの構造、即ち、接続部内を流れる水の圧力を受けない構造である場合には、カバー材は必ずしも接続部等に堅固に保持される必要はない。
【００１５】
両接続部の挿入構造は、水栓部品の接続部を固定ジョイントの接続部に挿入させる構造であってもよいし、固定ジョイントの接続部を吐水具の接続部に挿入させる構造であってもよい。また、固定ジョイントは、例えば、所定の「取付基部」に固定されるが、この「取付基部」としては、「水栓関連用品（例えば、シャワー装置、水栓）やその外郭部」、「浴室、洗面所、台所等の水栓の設置空間の壁面若しくはデッキ面（パネルで構成されるものを含む。）」、「浴室、洗面所、台所等の水栓の設置空間内に設置されるカウンター」等を例示できる。
【００１６】
請求項２の発明は、請求項１に記載の接続構造において、前記カバー材を、内周面に雌ネジ部を有する略円筒状に構成すると共に、両接続部のうちの何れかの接続部の外周面に設けられた雄ネジ部に対して、該雌ネジ部を螺合させることにより、前記カバー材を前記何れかの接続部に保持させることを特徴とする。
【００１７】
請求項２の接続構造によると、カバー材を、雄ネジ部を有する接続部に単にねじ込むだけで、カバー材の組付作業を完了する。即ち、別途の固着手段を使用することなく、カバー材の組付作業を完了するため、この組付作業の手間を少なくできる。
【００１８】
請求項３の発明では、請求項２に記載の接続構造において、前記固定ジョイントが所定の取付基部に固定され、前記固定ジョイントの接続部の外周面側における前記連結材の装着位置よりも、前記取付基部側の部位に前記雄ネジ部が配設され、
前記水栓用部材の接続部の外周面側に係止段部が配設されると共に、
前記カバー材が、前記雄ネジ部への螺合時に前記係止段部に当接する当接片部を、備えることを特徴とする。
【００１９】
請求項３の発明では、カバー材を固定ジョイントの接続部の雄ネジ部に螺合させて、当接片部と、水栓用部品の接続部の係止段部と、を当接させる。これにより、水栓用部品の接続部が固定ジョイントの接続部から抜けようとしても、カバー材自体がその当接片部を係止段部に当接させる。そして、この当接片部と係止段部との当接により、水栓用部品の接続部が押さえられ、水栓用部品の接続部がその抜け方向に移動することが規制させる。よって、請求項３の発明によると、水栓用部品と固定ジョイントとの接続強度を、一層向上させることができる。
【００２０】
請求項４の発明は、請求項１乃至請求項３の何れかに記載の接続構造において、前記水栓用部品は吐水具であることを特徴とする。
【００２１】
請求項４の発明は、「水栓用部品」の一具体例を示すものである。この「吐水具」としては、「トップシャワー用の吐水具（使用者の頭部や全身等にめがけて、湯水を噴出するトップシャワー吐水を行うためのもの）」、「ボディシャワー用の吐水具（使用者の身体に向かって略水平に湯水を噴出するボディシャワー吐水を行うためのもの）」、「打たせ湯シャワー用の吐水具（使用者に適度な刺激を与えるために、滝水等のように湯水を吐水するもの）」、「ミストシャワー用の吐水具（霧状に湯水を吐水するもの）」、「床散湯シャワー用の吐水具（床面を暖めること等を目的に用いられるもの）」、「眼球洗浄シャワー吐水用の吐水具（使用者の眼球を洗浄するために用いられるもの）」、「食器洗浄用のシャワー吐水具」等の「シャワー用の吐水具」の他に、カランや、浄水器用の吐水具等も含まれる。
【００２２】
請求項１〜請求項３の発明は、水栓部品のうちで、通常、使用者の頭上、頭部付近に配置されるもの（例えば、「トップシャワー用の吐水具」）に適用することが特に好ましい。使用者の頭上、頭部付近に配置される吐水具の抜け止めの万全を図ることは、使用者の安全をより確実に確保する上で望ましいからである。
【００２３】
尚、請求項１〜請求項３の発明においては、水栓部品として、「吐水具」以外のものも例示できる。例えば、「固定ジョイントが配置された壁面に固定されるシャワーヘッド用のフック」、「固定ジョイントが配置された水栓本体に装着される水栓用カバー」、「固定ジョイントが配置された水栓本体に接続される配管」、「固定ジョイントが接続された配管に接続される水栓本体」等を例示できる。
【００２４】
【発明の実施の形態】
次に、本各発明に係わる「接続構造」の実施の形態を図面に従って詳細に説明する。本実施の形態では、図１及び図２に示すように、請求項１〜請求項４の発明の「接続構造」の具体例として、「トップシャワー用の吐水具１７」への一適用例を例示する。
【００２５】
トップシャワー用の吐水具１７は、図１及び図２に示すように、シャワー装置の外郭部１（取付基部の一具体例を示すものであって、浴室の壁面や、浴室の壁面パネル等であってもよい。）に固定されるものである。即ち、このトップシャワー用の吐水具１７は「水栓用部品」の一具体例を示すと共に、連結材としてのネジ（ビス等の雄ネジ）２４と、カバー材２８とを利用して、シャワー装置の外郭部１に固定されている。尚、本実施の形態に係るシャワー装置（図示を省略）は、トップシャワー用の吐水具１７のみを備えてもよいし、他の吐水具（ボディシャワー用の吐水具、打たせ湯シャワー用の吐水具、ミストシャワー用の吐水具、床散湯シャワー用の吐水具、シャワーヘッド、カラン等）を備えてもよい。
【００２６】
本実施形態では、トップシャワー用の吐水具（水栓用部品の一具体例）１７の接続部１９を「一方の接続部」とし、固定ジョイント７の接続部９を「他方の接続部」とする。そして、一方の接続部１９に他方の接続部９が挿されて両接続部１９、９が重なり合う部分によって、各発明に示す「挿入部分」の一具体例を構成している。このうち、固定ジョイント７は、内部空間を通水部（通水路）７ａとする略円筒状に構成され、この通水部（通水路）７ａによって、トップシャワー用の吐水具１７から流出させる湯水（湯、水等）を通過させる。また、固定ジョイント７は、外郭部１の取付孔１ａに挿入される取付筒部８と、トップシャワー用の吐水具１７との接続に使用される接続部９と、を備えている。
【００２７】
取付筒部８の外周面にはナット５を螺合させる雄ネジ部８ａが形成されている。また、接続部９は、取付筒部８側の取付座１０と、先端側に設けられると共にトップシャワー用の吐水具１７の接続部１９に挿入される挿入筒部１２と、を備えている。更に、取付座１０は、外径寸法を取付筒部８や挿入筒部１２より大径とした円筒状とされ、その外周面には、カバー材２８の雌ネジ部２９に対応する雄ネジ部１１が設けられている。また、挿入筒部１２の外周面には、固定ジョイント７の半径方向（肉厚方向）に穿設された取付孔１３が開口している。尚、この取付孔１３の内壁面には雌ネジ部が形成されると共に、この取付孔１３は挿入筒部１２の下方側に開口している。
【００２８】
この固定ジョイント７においては、取付座１０が「外郭部１の前面における取付孔１ａの周縁の部位」に当接するまで、取付筒部８を外郭部１の取付孔１ａに挿入させる。そして、雄ネジ部８ａにナット５を螺合させ、取付座１０とナット５とで外郭部１を挟持することにより、この固定ジョイント７は外郭部１に固定される。尚、取付筒部８の後端部には湯水（湯、水）を供給するためのホース３が接続されている。このホース３は、雄ネジ部８ａに螺合する締め具２を利用して、取付筒部８の後端部に接続されている。尚、「取付筒部８の後端部と締め具２との間」、「ナット５と外郭部１の後面との間」、「取付座１０と外郭部１の前面との間」には、各々、水密性を確保するためのパッキン４、６、６１が配設されている。
【００２９】
トップシャワー用の吐水具１７は、揺動自在な本体部１８と、本体部１８の上端から固定ジョイント７の接続部９側に延びる接続部１９と、を備えている。この接続部１９の内部には通水部（通水路）１９ａが形成され、この通水部（通水路）１９ａによって、通水部（通水路）７ａと本体部１８とが連通される。そして、接続部１９には、接続時における接続部９の取付孔１３と対応する位置に、内外周を貫通する取付孔２２が設けられている。また、接続部１９の外周面側においては、取付孔２２よりも、更に外郭部１から離間する側の部位に係止段部としての鍔部２１を突出（全周にわたる鍔部を例示するが、全周の一部に形成される略円弧状の鍔部でもよい。）させている。
【００３０】
なお、係止段部として鍔部２１の他には図６に示すような態様が示される。すなわち、接続部１９を小径部１９ｅと大径部１９ｄとにより構成して大径部１９ｄを係止段部２１ｄとし、大径部１９ｄの側面に当接片部３０を当接するようにしても良い。また、係止段部は取付孔２２より外郭部寄りの部位に設けられていても良い。
【００３１】
連結材としてのネジ（雄ネジ）２４は、雄ネジを螺刻させた軸部２５と、頭部２６と、を備えている。尚、固定ジョイント７側の接続部９に、予め、雌ネジを設けた取付孔１３を形成していない場合には、このネジ２４としてタッピングネジを使用してもよい。
【００３２】
カバー材２８は略円筒状に構成され、内周面に固定ジョイント７の雄ネジ部１１に対応した雌ネジ部２９を備えている。そして、このカバー材２８においては、雌ネジ部２９から離間する端部側の内周面に、当接片部３０（例えば、全周にわたる当接片部３０や、全周のうちの一部に設けられた略円弧状の当接片部３０等）を突設させている。
【００３３】
尚、本実施の形態のカバー材２８では、トップシャワー用の吐水具１７と固定ジョイント７との接続を完了したときに、ネジ２４の頭部２６とその位置に対応するカバー材２８の内周面２８ａとの間に隙間ｈ（図２）が生ずる。この隙間ｈは以下のように設定されている。即ち、ネジ（雄ネジ）２４の軸部２５が緩んで、この軸部２５が内側の接続部９（他方の接続部）から若干抜けようとしても、頭部２６を内周面２５ａに当接させ、軸部２５の抜け方向への移動を規制する。これにより、軸部２５が両接続部９、１９に装着された状態を維持し、接続部９、１９相互が抜けようとすることを防止できるように設定されている。但し、この隙間ｈを無くすこともできるが、カバー材２８の組付作業の際に、ネジ（雄ネジ）２４の頭部２６とカバー材２８とが干渉せず、この作業を円滑に行うためには設けておくことが望ましい。
【００３４】
本トップシャワー用の吐水具１７を固定ジョイント７に接続する際には、予め、固定ジョイント７を外郭部１に固定する。また、カバー材２８を、予め、トップシャワー用の吐水具１７の接続部１９に外装し、さらに、本体部１８側に配置する。そして、接続時には、先ず、パッキン１５を外装した固定ジョイント７の接続部９を、トップシャワー用の吐水具１７の接続部１９に挿入させるように、接続部１９を接続部９に外装すると共に、取付孔１３、２２を位置合わせする。次いで、ネジ２４（雄ネジ）を、取付孔２２、取付孔１３の順に締め込む。更に、カバー材２８の雌ネジ部２９を固定ジョイント７の雄ネジ部１１に螺合させ、カバー材２８の当接片部３０をトップシャワー用の吐水具１７の鍔部２１に当接させれば、トップシャワー用の吐水具１７を固定ジョイント７に接続することができる。
【００３５】
以上のように構成される接続構造においては、トップシャワー用の吐水具１７と固定ジョイント７との接続後に、ネジ２４が緩み、接続部９から抜けようとしても、カバー材２８の内周面２８ａが、ネジ２４の抜け方向側の端部である頭部２６に当接する。よって、ネジ２４が両接続部９、１９から抜けることが防止され、トップシャワー用の吐水具１７が固定ジョイント７から抜けることを確実に防止できる。
【００３６】
また、カバー材２８が、内周面に雌ネジ部２９を有する略円筒状に構成され、一方の接続部９の外周面に設けられた雄ネジ部１１に螺合されて接続部９に保持されている。このため、カバー材２８を、雄ネジ部１１を有する接続部９に単にねじ込むだけで、接続構造に組み込むことができるため、トップシャワー用の吐水具１７と固定ジョイント７との接続作業において、カバー材２８の組付作業を簡単に行なうことができる。
【００３７】
特に、固定ジョイント７の接続部９の外周面側におけるネジ（雄ネジ）２４の装着位置（取付孔１３の位置）よりも、外郭部１側の部位に雄ネジ部１１が配設されると共に、トップシャワー用の吐水具１７の接続部１９の外周面側におけるネジ２４の装着位置（取付孔２２の位置）よりも、外郭部１から離間する側の部位に鍔部２１が配設されている。そして、カバー材２８には、雄ネジ部１１への螺合時に、鍔部２１に当接する当接片部３０が設けられている。このため、カバー材２８を固定ジョイント７の接続部９の雄ネジ部１１に螺合させて、当接片部３０をトップシャワー用の吐水具１７の接続部１９の鍔部２１に当接させれば、トップシャワー用の吐水具１７の接続部１９が、固定ジョイント７の接続部９から抜けようとして、外郭部１から離れようとしても、当接片部３０と鍔部２１とが当接し、トップシャワー用の吐水具１７の接続部１９は押さえ込まれる。即ち、カバー材２８によっても、トップシャワー用の吐水具１７が固定ジョイント７から抜けることを防止する構造となっている。
【００３８】
尚、本各発明の範囲は、前記発明の実施の形態に限定されるものでなく、更に種々の変形例を例示できる。即ち、図３に示す接続構造を例示することもできる。即ち、図３に示す変形例は、（１）接続部１９が鍔部２１を備えない点と、（２）カバー材２８Ａが当接片部３０を備えない点とが、本実施の形態と異なっている。この変形例においても、カバー材２８Ａを、雄ネジ部１１を有する接続部９に単にねじ込むだけ、つまり、別途の固着手段（ネジ部材等）を使用しなくても、このカバー材２８Ａを接続構造に組み込むことができる。
【００３９】
更に、これらのカバー材２８、２８Ａは、連結材としてのネジ２４の端部２６を覆うことができれば、トップシャワー用の吐水具１７及び固定ジョイント７とのうちの何れの側の接続部１９、９に保持されてもよいし、両者の接続部１９、９に保持されてもよい。また、請求項１の発明等においては、カバー材を、「水栓用部品の接続部」及び「固定ジョイントの接続部」のうちの少なくとも一方に対して別途の固着手段を用いて固定してもよいし、「水栓用部品の接続部」及び「固定ジョイントの接続部」とは別途の部材に対して別途の固着手段を用いて固定してもよい。更に、「水栓用部品の接続部」及び「固定ジョイントの接続部」の周囲に配置される別途の部品の一部によって、カバー材を構成してもよい。
【００４０】
また、カバー材は、連結材の抜け方向側の端部（頭部）を覆って連結材の抜け止めを図れる程度に、所定の接続部に保持されていればよい。例えば、図４及び図５に示す変形例のように、カバー材２８Ｂに爪片からなる係止部３１、３１を設ける。そして、接続部１９側に、係止部３１、３１を係止する係止部２３、２３を設け、接続部９に対してカバー材２８Ｂを係止して保持してもよい。
【００４１】
更に、連結材としては、接続部９、１９に締め付けるネジ（雄ネジ）２４の他、接続部９、１９に嵌め込んだり、圧入する等のピンを使用してもよい。また、接続部９、１９の挿入構造は、固定ジョイント７側の接続部９をトップシャワー用の吐水具１７等の吐水具側の接続部１９に挿入させる構造としてもよし、トップシャワー用の吐水具１７等の吐水具側の接続部１９を固定ジョイント７側の接続部９に挿入させる構造としてもよい。更に、カバー材２８の内周面２８ａと、ネジ（雄ネジ）２４の連結材における挿入部分からの抜け方向側の端部と、の間の隙間が大きくなり、カバー材２８が抜け止め機能を発揮できない場合には、この内周面２８ａに、カバー材２８の半径内側方向に突出する突部を形成し、この間隔を狭くすればよい。
【００４２】
【発明の効果】
以上のように、本各発明の接続構造によると、連結材が挿入部分から抜けることを防止することによって、水栓用部品が固定ジョイントから抜けることを確実に防止できる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a connection structure between a faucet component and a fixed joint.
[0002]
[Prior art]
Some faucet parts are fixed to a mounting base (for example, an outer shell of a device or a wall surface of a bathroom). For example, among water spouting devices (such as a water spouting device for a top shower), there are a water fixing device fixed to an outer portion of a shower device (for example, see Patent Literature 1) and a water fixing device fixed to a wall surface of a bathroom. In such a fixing structure, a fixed joint may be fixed to the mounting base, and a faucet component may be fixed to the fixed joint.
[0003]
At the time of this fixing, it is possible to insert the other into one of the connecting part of the faucet part and the connecting part of the fixed joint, and attach a retaining screw to the insertion part formed by this insertion. is there.

JP-A-11-315561 (FIGS. 2 and 4)
[0005]
[Problems to be solved by the invention]
However, in this connection structure, when the screw is loosened and comes off, the faucet component comes off the fixed joint. Therefore, it is necessary to prevent the screws from coming off and to make the connection structure between the faucet component and the fixed joint more robust.
[0006]
SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and a faucet component and a fixed joint that can prevent a connecting member from coming off from an insertion portion and reliably prevent a faucet component from coming off a fixed joint. The purpose of the present invention is to provide a connection structure with the device.
[0007]
[Means for Solving the Problems]
The connection structure between the faucet component and the fixed joint according to the first aspect of the present invention (hereinafter, may be simply referred to as a “connection structure”) includes a connection portion of a predetermined faucet component and a connection portion of a predetermined fixed joint. In an insertion portion configured by inserting the other into one of the connection portions, from the outside of the insertion portion, a connecting member for retaining is mounted in a state from one connection portion to the other connection portion, A connection structure between a faucet part and a fixed joint, configured by connecting both connection parts,
The cover member covers an end of the connecting member on the side in which the insertion portion is removed from the insertion portion and regulates the movement of the connecting member in the removing direction.
[0008]
According to the first aspect of the present invention, even when the connecting member is loosened or the like and tries to come out of the insertion portion, the cover member contacts the end of the connecting member on the side in which the connecting member comes off. That is, since the connecting member restricts the free movement of the connecting member along the pull-out direction, the connecting member is prevented from falling out of the insertion portion, and the faucet component is prevented from falling out of the fixed joint. Is done.
[0009]
Here, the connecting part of the faucet part and the connecting part of the fixed joint may both be cylindrical connecting parts (cylindrical connecting parts), or the connecting parts disposed outside may be cylindrical connecting parts. If it is a part (cylindrical connection part), the connection part inserted into this connection part may be a solid (columnar) connection part. If it is desired to use at least one of the internal spaces as the water passage part, the connection part to be the water passage part may be a cylindrical connection part (cylindrical connection part). Further, the “cylindrical shape” described here is not limited to a cylindrical shape, and may be a cylindrical shape having a polygonal cross section such as a triangle or a square.
[0010]
The cover member may cover the end portion while abutting on the “end portion of the connection member on the side of the insertion portion from the insertion portion (hereinafter, appropriately referred to as“ the end portion ”). A predetermined gap may be provided between the cover member and the end. For example, when the connecting member is attached along the “direction of the shortest distance between the cover member and the end portion (the radial direction when the connecting portion forming the insertion portion is cylindrical), From the total length of the material (the total length along the mounting direction) to the length of the connecting material to the other connecting portion of the connecting material (the length along the mounting direction, which is embedded in the other connecting portion and mounted. Is larger than the gap (shortest distance) between the end portion and the cover material, the cover material is connected even if a gap exists between the end portion and the cover material. This is because the material can be prevented from coming off.
[0011]
In other words, even if the connecting member loosens, etc., and tries to come out of the insertion portion slightly (by the shortest distance), the connecting member comes into contact with the cover member and further movement is restricted, so that the connecting member still remains. It is possible to maintain the state of being attached to both connection parts constituting the insertion part. In this case, it is more preferable that a gap of “1 mm to 5 mm” is secured between the end portion and the cover material. If the gap is less than 1 mm, the end may come into contact with the cover material when the cover material is mounted, and the work of mounting the cover material may not be performed efficiently. On the other hand, if it exceeds 5 mm, the rattling may increase when the connecting member is loosened.
[0012]
As described above, the connecting member may be attached to the insertion portion in the direction of the shortest distance (in the case where both connecting portions are cylindrical, for example, in the radial direction of both connecting portions). It may be mounted in a direction inclined with respect to the direction of the shortest distance (inclination angle smaller than 90 degrees). That is, as described above, when the cover member is attached along a direction that forms a predetermined angle with the direction of the shortest distance between the cover member and the end portion, the total length of the connecting member (the total length along the insertion direction) is reduced. From the “projection length” to the “direction of the shortest distance” (when the predetermined angle is α degrees and the total length of the connecting member is L, the length indicated by L · COSα) is changed to “the mounting length of the connecting member to the other connecting portion. The length obtained by subtracting the “projection length (when the predetermined angle is α degrees and the mounting length is M, the length indicated by M · COSα)” to the “shortest distance direction” of Is larger than the gap (shortest distance) between the cover member and the cover member, even if a gap exists between the end portion and the cover member.
[0013]
The “connecting material” includes an exposed portion (for example, a head) that is exposed to the outside of the insertion portion, such as a “male screw (such as a screw)” or a “pin”, and a threaded or screwed insertion portion. And an embedded portion (for example, a shaft portion) mounted in a shape, a loose fitting shape, a press-fitting shape, or the like, and is not limited to a device having an embedded portion (for example, a shaft portion). You may. More specifically, a mounting hole (regardless of whether or not a female screw is provided on the inner wall surface) is provided at a position of both connecting portions constituting the insertion portion so as to be mutually alignable. In this case, a male screw (such as a screw) that is screwed or screwed into the mounting hole, a “male screw (such as a screw) that is screwed into the insertion portion and mounted in this portion”, “ When the mounting holes are provided in the two connecting portions constituting the insertion portion in such a manner that they can be aligned with each other, the pins mounted in the mounting holes (even if they are loosely inserted, they are inserted in a press-fit shape). May be performed.) ".

In addition, the “cover material” may be configured by a part for the faucet and a part arranged outside the fixed joint. Even when the connection part of the faucet part or the fixed joint constitutes the water passage part, the cover member only covers the end of the connection member on the side of the withdrawal direction, that is, the pressure of the water flowing through the connection part. In the case of a structure that is not affected by the cover member, the cover member does not necessarily need to be firmly held at the connection portion or the like.
[0015]
The insertion structure of the two connecting portions may be a structure in which the connecting portion of the faucet component is inserted into the connecting portion of the fixed joint, or a structure in which the connecting portion of the fixed joint is inserted into the connecting portion of the water discharging device. Good. The fixed joint is fixed to, for example, a predetermined “mounting base”. The “mounting base” includes “water faucet-related articles (eg, a shower device, a faucet) and its shell”, and “bathroom”. Counters installed in the faucet installation space of bathrooms, lavatories, kitchens, etc. " And the like.
