【０００２】
【従来の技術】
本出願人は、水栓への供給流路を形成する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挿通してある蛇腹状の鞘管を保持する鞘管ホルダを開発中である。
【０００３】
それは、鞘管ホルダ本体を別途用意する必要がなく、共通の鞘管ホルダ本体でサイズの異なる鞘管に対応できるよう構成されたものである。
【０００４】
【発明が解決しようとする課題】
しかし、鞘管ホルダを構成する残りの二部材、すなわち、鞘管の溝に係合する複数の内爪を内周面に有する爪リング体と、前記内爪が前記溝から抜けるのを防止するよう前記爪リング体が着脱自在に装着される抜け止めリング体は、鞘管のサイズに合わせて交換しなければならず、サイズの異なる鞘管への対応に問題があった。
【０００５】
また、前記二部材を、前記爪リング体の機能と抜け止めリング体の機能を持った一部材に変更してサイズの異なる鞘管への対応ができるタイプの鞘管ホルダがあるけれども、これは２分割部材で構成されており、鞘管を取り付けるときに手間がかかるおそれがある。
【０００６】
この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、鞘管の取り付けが容易で部品点数が少なく、かつ、サイズの異なる鞘管に対応できる鞘管ホルダを提供することである。
【０００７】
【課題を解決するための手段】
上記目的を達成するために、この発明の鞘管ホルダは、水栓への供給流路を形成する樹脂パイプを挿通してある蛇腹状の鞘管を保持する鞘管ホルダにおいて、水栓側に設けた樹脂パイプ挿通用開口部に連通する鞘管挿入穴を有する状態で前記樹脂パイプ挿通用開口部に連設される鞘管ホルダ本体と、前記鞘管ホルダ本体に着脱自在に装着されるとともに鞘管が挿入される爪リング体とを備え、更に、この爪リング体は、前記爪リング体内に挿入される鞘管の溝に係合する複数の内爪をそれぞれ上部および下部に有し、外径の異なる鞘管がそれぞれ挿入可能なように、前記爪リング体の中心軸と前記上部の内爪の先端間の径方向における距離が、前記爪リング体の中心軸および前記下部の内爪の先端間の径方向における距離よりも小さく設定されているとともに、鞘管ホルダ本体は係止窓を有し、また、爪リング体は前記係止窓に係合する係合足を有し、前記係止窓と係合足とで、鞘管が挿入された爪リング体を鞘管ホルダ本体の前記鞘管挿入穴に挿入して爪リング体を鞘管ホルダ本体に装着したときに、爪リング体が前記鞘管ホルダ本体から抜けるのを防止する爪リング体抜け止め手段が構成される。
【０００８】
【発明の実施の形態】
以下、この発明の実施形態について説明する。
図１〜図９は、この発明の一実施形態を示す。
【０００９】
図１〜図９において、１は、樹脂製の鞘管ホルダである。この実施形態では、外径の異なる二つの蛇腹状の鞘管Ａ，Ｂがそれぞれ挿入可能なように構成されている鞘管ホルダ１を示す。この鞘管ホルダ１は、吐出口部２ｄから給水ホースを介して例えば洗濯機へ給水する水栓２への水導入流路（供給流路）ｉを形成する樹脂パイプ３を挿通してある鞘管Ａまたは鞘管Ｂを保持する機能を有する。また、水栓２は、樹脂パイプ３の下流端３ａに接続する接続部３０を有する。
【００１０】
前記鞘管ホルダ１は、略筒状で、樹脂製の鞘管ホルダ本体５と、この鞘管ホルダ本体５に着脱自在に装着されるとともに、外径の異なる二つの鞘管Ａ，Ｂが挿入される樹脂製の爪リング体６とを備えている。鞘管Ａよりも鞘管Ｂの外径が大である。
【００１１】
前記鞘管ホルダ本体５は、水栓２のハウジング底部２ａに設けた平面視略円形の樹脂パイプ挿通用開口部７に連通する鞘管挿入穴８を有するとともに、樹脂パイプ挿通用開口部７に連設されている。前記鞘管ホルダ本体５は、上部小径部１６と下部大径部１７よりなり、下部大径部１７は、一対の係止窓１８を有する。
【００１２】
一方、前記爪リング体６は、爪リング体６内に挿入される外径の小さな鞘管Ａの溝９に係合する複数の内爪１０を上部に有するとともに、爪リング体６内に挿入される、鞘管Ａよりも大きな外径を有する鞘管Ｂの溝９ａに係合する複数の内爪１１を下部に有する。内爪１０（以下、上部内爪という）は、前記爪リング体６の内周面の上部における同一高さの位置に円周方向に沿って複数個設けられており、同一形状である。また、内爪１１（以下、下部内爪という）は、前記爪リング体６の内周面の下部における同一高さの位置に円周方向に沿って複数個設けられており、同一形状である。１２は、前記爪リング６の中心軸であり、Ｏは、中心軸１２が通る円の中心を示す。
【００１３】
この実施形態では、前記爪リング体６は、複数の前記上部内爪１０を有する上部小径体１３と、複数の前記下部内爪１１を有する下部大径体１４とより構成されている。また、上部内爪１０の内向き先端１０ａは、下部内爪１１の内向き先端１１ａよりも長さＨだけ高い位置に設けられている。なお、図１において、ａは、上部内爪１０と上部小径体１３間に形成されたスリット状の溝である。このスリット状の溝ａによって上部内爪１０を弾性変形し易くできる。また、ｂは、上部内爪１０の直上に形成された切欠である。また、ｃは、下部内爪１１の直上に形成された切欠である。また、ｅは、下部内爪１１と下部大径体１４間に形成されたスリット状の溝である。このスリット状の溝ｅによって下部内爪１１を弾性変形し易くできる。
【００１４】
そして、上部内爪１０が、爪リング体６内に挿入される外径の小さな鞘管Ａの溝９に係合するよう、また、下部内爪１１が、爪リング体６内に挿入される外径の大きな鞘管Ｂの溝９ａに係合するよう、前記中心軸１２と前記上部内爪１０の内向き先端１０ａ間の爪リング体６の径方向における距離ｄ（一定値）は、前記中心軸１２と前記下部内爪１１の内向き先端１１ａ間の爪リング体６の径方向における距離Ｄ（一定値）よりも小さく設定されている。つまり、複数の上部内爪１０が鞘管Ａの溝９に係合可能な距離として、各上部内爪１０の内向き先端１０ａと中心Ｏ間の距離がｄ（一定値）に設定されている。また、複数の下部内爪１１が鞘管Ｂの溝９ａに係合するよう各下部内爪１１の内向き先端１１ａと中心Ｏ間の距離がＤ（＞ｄ）に設定されている。
【００１５】
そして、爪リング体６は、距離ｄ（一定値）を維持しながら鞘管Ａの溝９に上部内爪１０が係合した状態で、鞘管ホルダ本体５の鞘管挿入穴８に挿入される。また、爪リング体６は、距離Ｄ（一定値）を維持しながら鞘管Ｂの溝９ａに下部内爪１１が係合した状態で、鞘管ホルダ本体５の鞘管挿入穴８に挿入される。
【００１６】
例えば、距離ｄ（一定値）を維持しながら複数の前記上部内爪１０が鞘管Ａの溝９に係合した状態で、爪リング体６の上部小径体１３が鞘管ホルダ本体５の上部小径部１６内に挿入可能なように、上部小径体１３の外径と鞘管ホルダ本体５の上部小径部１６の内径が設定されている。
【００１７】
同様に、距離Ｄ（一定値）を維持しながら複数の前記下部内爪１１が鞘管Ｂの溝９ａに係合した状態で、下部大径体１４が鞘管ホルダ本体５の下部大径部１７内に挿入可能なように、下部大径体１４の外径と鞘管ホルダ本体５の下部大径部１７の内径が設定されている。
【００１８】
そして、鞘管Ａの溝９に上部内爪１０を係合させる場合、鞘管Ａの山９ｂに上部内爪１０が当たるたびに、上部内爪１０が外向きに弾性変形して前記中心Ｏと前記上部内爪１０の内向き先端１０ａ間の距離が距離ｄ（一定値）よりも大きくなるが、上部内爪１０が溝９に嵌まると内向きに弾性復帰し、上部内爪１０が溝９に係合した状態では、中心Ｏと前記上部内爪１０の内向き先端１０ａ間の距離はｄ（一定値）を維持することになる。また、同様に、下部内爪１１が鞘管Ｂの溝９ａに係合した状態では、中心Ｏと前記下部内爪１１の内向き先端１１ａ間の距離はＤ（一定値）を維持することになる。
【００１９】
更に、下部大径体１４は、前記一対の係止窓１８にそれぞれ係合する係合足１９を有する。
【００２０】
また、前記爪リング体６と鞘管ホルダ本体５は、鞘管Ａまたは鞘管Ｂが挿入された爪リング体６を鞘管ホルダ本体５に装着したときに、爪リング体６が前記鞘管ホルダ本体５から抜けるのを防止する爪リング体抜け止め手段を有する。
【００２１】
この爪リング体抜け止め手段は、前記一対の係止窓１８と前記一対の係合足１９とで構成される。
【００２２】
而して、水栓２の接続部３０に樹脂パイプ３が接続された状態で、外径の小さな鞘管Ａを保持するには、爪リング体６内に鞘管Ａを挿入して鞘管Ａの溝９に複数の上部内爪１０を係合させる。その後、爪リング体６を鞘管ホルダ本体５の鞘管挿入穴８に挿入して係止窓１８に係合足１９を係合させる。
【００２３】
また、水栓２の接続部３０に樹脂パイプ３が接続された状態で、外径の大きな鞘管Ｂを保持するには、爪リング体６内に鞘管Ｂを挿入して鞘管Ｂの溝９ａに複数の下部内爪１１を係合させる。その後、爪リング体６を鞘管ホルダ本体５の鞘管挿入穴８に挿入して係止窓１８に係合足１９を係合させる。
【００２４】
このように、外径の異なる二つの鞘管Ａ，Ｂに一組の鞘管ホルダ１だけで対応できるとともに、取り付けも簡単にできる。
【００２５】
図１０は、給水および給湯用の水栓２’に適用したこの発明の他の実施形態を示す。図１０において、図１〜図９に示した符号と同一のものは、同一または相当物である。
【００２６】
水栓２’の例えば湯側接続部３０’に樹脂パイプ（図示せず）が接続された状態で、外径の小さな鞘管Ａを保持するには、湯側に使用する爪リング体６内に鞘管Ａを挿入して鞘管Ａの溝９に複数の上部内爪１０を係合させる。水栓２’の水側接続部３０’’に外径の小さな鞘管Ａを保持する場合も同様である。
【００２７】
