【発明の属する技術分野】
この発明は、ロックレバーを有する給水ホースと水栓の給水口部との接続機構に関する。
【０００２】
【従来の技術および発明が解決しようとする課題】
従来この種の接続機構の一例として、図９に示すように、鍔部材７０が下流側に一体形成されたＬ型ニップル本体７０ａの上流側の接続部７１に上流側に向かって、袋ナット７２と、この袋ナット７２とで水栓７３の給水口部７４からの抜けを防止する割りリング７５と、給水口部７４の入口開口に内嵌されるシール部材７６とを順次備えた洗濯機給水ホース用ニップル７７を給水口部７４に差し込み袋ナット７２と給水口部７４をねじ止めしたものがあるけれども、ニップル７７にかかる回転方向以外の力によって袋ナット７２に当接していた割りリング７５が溝７８から外れてニップル本体７０ａ自体が給水口部７４から外れてしまうことがある。
【０００３】
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、ロックレバーを有する給水ホースと水栓の給水口部を確実に接続できるロックレバーを有する給水ホースと水栓の給水口部との接続機構を提供することである。
【０００４】
【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、ロックレバーを有する給水ホースと水栓の給水口部との接続機構において、前記給水口部の外周面に給水流路の下流側から上流側に向かって、給水ホース側継手のロックボールが嵌まり込む環状ロック溝、抜け止め防止用の環状溝および当たり部を順次設ける一方、下流側から前記給水口部に着脱可能に嵌め込まれ、前記当たり部に当接する鍔部材と、この鍔部材に続いて下流側から前記給水口部に嵌め込まれ、前記抜け止め防止用の環状溝に嵌まり込み、それによって、前記ロックレバーが前記鍔部材に係止される接続時には前記鍔部材に当接した状態で前記鍔部材の前記給水口部からの抜けを防止しうる割りリングとを備えている。
【０００５】
また、この発明は別の観点から、ロックレバーを有する給水ホースと水栓の給水口部との接続機構において、前記給水口部の外周面に給水流路の下流側から上流側に向かって、給水ホース側継手のロックボールが嵌まり込む環状ロック溝、環状固定溝を順次設ける一方、この環状固定溝に嵌まり込む小径の開口部および下流側から前記給水口部が挿通可能な大きさを有する大径の開口部よりなるダルマ状の開口が形成された鍔部材と、この鍔部材に前記大径の開口部を介して前記給水口部を挿通させた後前記環状固定溝に前記小径の開口部を嵌め込んだ状態で、下流側から前記大径の開口部に嵌め込み可能に係止され、それによって、前記ロックレバーが前記鍔部材に係止される接続時には前記鍔部材の前記小径の開口部からの抜け止めを防止しうる抜け止め防止部材とを備えたことを特徴とするロックレバーを有する給水ホースと水栓の給水口部との接続機構を提供する。
【０００６】
【発明の実施の形態】
以下、この発明の実施の形態について説明する。
図１〜図３は、本願出願人が先に提案（特願２０００−１７０９６７号・現時点では未公開。）した水道用コンセント（以下、先行例という）に適用したこの発明の第１の実施形態を示す。この実施形態では、給水ホースとして洗濯機用給水ホースを採用している。
図１〜図３において、まず、水道用コンセント１の全体構成について簡単に説明する。
水道用コンセント１は、ほぼ直方体形状のハウジング本体９に着脱可能な枠体２ｂと、この枠体２ｂに着脱可能な中央部２ａとを有する。この中央部２ａは、上開口４および下開口５を有し、前記上開口４にダイヤル型の流量調整ハンドル６が配置され、前記下開口５に、洗濯機の給水ホース（図示せず）の上流端に設けられた継手部材（給水ホース側継手）７が着脱自在である継手部（以下、給水口部という）８が配置されている。１２は、水栓本体で、水または湯の流入口１０および流出口（給水口）１１を有するとともに、セラミック製の固定ディスクおよび可動ディスクを内蔵するカートリッジ式の弁体１３を収容する。更に、中央部２ａには凹所１４が形成され、前記下開口５はこの凹所１４の底部１４ａに形成されている。
【０００７】
更に、前記給水口部８は、ほぼ円筒状で、流出口（給水口）１１に水平状態で接続される上流側筒部分８ａと、下流側筒部分８ｂとよりなり、水平配置される前記上流側筒部分８ａの水平中心軸Ｘに対して下流側筒部分８ｂが下向き（水平中心軸Ｘに直角なＹ方向）に所定角度θだけ傾斜している。この傾斜角θは鋭角である。また、両筒部分８ａ，８ｂの外径は等しい。
【０００８】
また、この実施形態では、ハウジング本体９に枠体２ｂを介して中央部２ａを取り付けた状態で前記給水口部８が袋ナット１５によって前記給水口１１のまわりに３６０°回転可能なようになっている。そのため、中央部２ａに前記凹所１４が形成されており、前記給水口部８や後述する鍔部材３２が中央部２ａに当接することはない。
【０００９】
ところで、前記給水口部８と給水ホース側継手７の接続機構は前記先行例において詳細に説明されているので省略する。
【００１０】
なお、給水口部８の前記下流側筒部分８ｂの外周面に環状ロック溝部２９が設けられている。給水口部８と給水ホース側継手７の接続時には、このロック溝部２９に給水ホース側継手７のロックボール（後述する）２１が嵌まり込む。また、前記下流側筒部分８ｂ内には、下流側から順に、弁座部材１６と、この弁座部材１６に上流側から当接可能な弁体部１７を有するストップ弁１８と、ストップ弁１８を下流側へと付勢する弾性部材１９とが設けられている。２０はシール部材である。
【００１１】
一方、給水ホース側継手７も、ほぼ円筒状の部材であり、その内壁には、上流側から順に、前記ロック溝部１５を係止するための四つのロックボール２１、２１と、前記下流側筒部分８ｂの外周面に当接可能なシール部材２２と、内径が小さくなる小径部２３とが形成されている。また、２４は、ほぼ円筒状の摺動部材であり、給水ホース側継手７の外壁に沿って、給水ホース側継手７の軸芯方向に摺動可能であるとともに、スプリング２５によって常に上流側へ付勢されている。
【００１２】
以下この発明の特徴的構成について説明する。
【００１３】
２６は、ロックレバーで、摺動部材２４の外壁に一体に形成されている。このロックレバー２６は、給水口部８と給水ホース側継手７の接続時に給水ホース側継手７が給水口部８から抜け落ちるのを防止するためのものである。
【００１４】
そして、前記給水口部８の下流側筒部分８ｂの外周面には、給水流路の下流側から上流側に向かって、前記接続時に給水ホース側継手７のロックボール２１が嵌まり込む前記環状ロック溝２９、抜け止め防止用の環状溝３０および当たり部３１が順次設けられている。前記当たり部３１は、溝部材３３から段差部分ｎを介して連設された谷３１ａと、段差部分ｍを介して連設された山３１ｂとよりなる。すなわち、前記谷３１ａは、溝部材３３の内径ｄより大きな外径Ｄ₁を有する。また、前記山３１ｂは谷３１ａの外径Ｄ₁よりも大きな外径Ｄ₂を有する。
【００１５】
一方、３２は、下流側から前記給水口部８に嵌め込まれ前記当たり部３１に当接する鍔部材である。この鍔部材３２は、図２（Ａ）、図２（Ｄ）に示すように、ほぼ皿状で、中央穴３６のまわりに形成された内側平坦部３７と、傾斜部３８と、外側平坦部３９とより構成されている。前記中央穴３６の径は谷３１ａの外径Ｄ₁に等しい。また、内側平坦部３７と前記谷３１ａの厚みは同一であり、前記傾斜部３８および外側平坦部３９の厚みも内側平坦部３７とほぼ同一である。
【００１６】
４０は、前記鍔部材３２に続いて下流側から前記給水口部８に嵌め込まれ、前記抜け止め防止用の環状溝３０に嵌まり込む割りリングで、図２（Ｂ）、図２（Ｃ）に示すように、２７０°の円周角を有し、中央穴４１の径は溝部材３３の内径ｄに等しい。
【００１７】
而して、前記鍔部材３２を前記給水口部８の下流側から前記給水口部８に嵌め込み、当たり部３１の段差部分ｍに内側平坦部３７の裏面内周端部３７ａが当接する。
【００１８】
前記鍔部材３２に続いて前記給水口部８の下流側から割りリング４０を前記給水口部８に嵌め込み、前記抜け止め防止用の環状溝３０に嵌め込む。このとき、割りリング４０の裏面内周端部４０ａが当たり部３１の段差部分ｎに当接するとともに、内側平坦部３７の表面内周端部３７ｂが当接する。更に、前記ロックレバー２６の先端に形成された爪２６ａが前記鍔部材３２の外側平坦部３９の裏面部３９ａに係止される。それによって、給水口部８と給水ホース側継手７を確実に接続できる。すなわち、回転方向以外の力が給水口部８にかかっても、給水口部８に設けたロック溝部２９に給水ホース側継手７のロックボール２１が嵌まり込むとともに、給水口部８に鍔部材３２および割りリング４０を固定しているので、割りリング４０が抜け止め防止用の環状溝３０から外れてしまうことはなく、給水口部８と給水ホース側継手７を強固に接続できる。
【００１９】
図４は、洗濯機用水栓等に用いられる単水栓５０に適用したこの発明の第２の実施形態を示す。図４において、図１〜図３に示した符号と同一のものは、同一または相当物である。
【００２０】
この場合、単水栓５０の給水口部８の下流側筒部分８ｂの外周面に、給水流路の下流側から上流側に向かって、接続時に給水ホース側継手７のロックボール２１が嵌まり込む環状ロック溝２９、抜け止め防止用の環状溝３０および当たり部３１が順次設けられている。
【００２１】
図５〜図８は、ダルマ状の開口が形成された鍔部材を用いたこの発明の第３の実施形態を示す。図５〜図８において、図１〜図４に示した符号と同一のものは、同一または相当物である。
【００２２】
図５〜図８において、水道用コンセント１の給水口部８の下流側筒部分８ｂの外周面に、給水流路の下流側から上流側に向かって、接続時に給水ホース側継手７のロックボール２１が嵌まり込む環状ロック溝２９、環状固定溝５１が順次設けられている。
【００２３】
５２は、ロックレバー２６を係止する鍔部材である。この鍔部材５２は、円板状で、中央において上下方向にダルマ状の開口５３を有する。この開口５３は、小径の開口部５４を上部に有する一方、大径の開口部５５を下部に有する。
【００２４】
前記小径の開口部５４は、この実施形態では２２２°の中心角αを有する状態で形成される一方、前記大径の開口部５５は、この実施形態では２６０°の中心角βを有する状態で形成されている。なお、中心角αは、１８０〜２３０°が好ましく、中心角βは２３０〜２６５°が好ましい。
【００２５】
前記大径の開口部５５の内径は、前記下流側筒部分８ｂの外径Ｋよりも大きく設定されている。また、前記小径の開口部５４は、環状固定溝５１の外径ｄ₁に略等しい直径を有する。
【００２６】
前記鍔部材５２は下流側から前記下流側筒部分８ｂに嵌め込まれるが、前記大径の開口部５５の周縁には段差５６が形成されている。そして、この段差５６を境に鍔部材５２の上流側面Ｎの側には径方向に突出した高所部分５７が形成され、鍔部材５２の下流側面Ｍの側には低所部分５９が形成されている。これら段差５６、高所部分５７、低所部分５９で係止部が構成される。
【００２７】
６０は、抜け止め防止部材である。ところで、前記鍔部材５２に前記大径の開口部５５を介して前記下流側筒部分８ｂを挿通させた〔図８（Ｂ）参照〕後、前記下流側筒部分８ｂを、図８（Ｂ）に示すように、矢印Ｕで示す上方向に移動させることにより前記環状固定溝２９に前記小径の開口部５４を嵌め込む〔図６（Ｂ）参照〕ことにより、鍔部材５２を給水口部８に固定設置する。この嵌め込み状態では、前記大径の開口部５５が開いている。仮に、前記大径の開口部５５が開いた状態で、ロックレバー２６を鍔部材５２に係止させると、鍔部材５２が、前記小径の開口部５４から抜け落ちるおそれがある。そこで、開いている前記大径の開口部５５を覆うように下流側から前記抜け止め防止部材６０を前記大径の開口部５５に嵌め込むことにより前記抜け止め防止部材６０を鍔部材５２に係止する。これにより、ロックレバー２６が鍔部材５２に係止される接続時において鍔部材５２が前記小径の開口部５４から抜けるのを防止できる。
【００２８】
前記抜け止め防止部材６０は、上述したように、前記小径の開口部５４を介して環状固定溝２９に鍔部材５２を固定設置した状態では大径の開口部５５が開いているので、この開き部分を隙間なく埋めるような形状を有する。
【００２９】
すなわち、前記抜け止め防止部材６０は、正面視が前記開き部分と同一の形状をなしており、平坦な一方面（下流側面）Ｍ’と、最下部に爪部６１が形成された平坦な他方面（上流側面）Ｎ’とを有する。前記爪部６１は、前記係止部５６，５７，５９に係合する。
【００３０】
更に、前記抜け止め防止部材６０は、前記爪部６１を有するとともに、上部に前記下流側筒部分８ｂの外周面に対応する形状の上側円弧部６３と、下部に前記大径の開口部５５に対応する形状の下側円弧部６４を有する。すなわち、抜け止め防止部材６０は、下流側筒部分８ｂと大径の開口部５５に挟まれた形で鍔部材５２に装着される。
【００３１】
前記上側円弧部６３は、装着時、環状固定溝２９の位置に対応する前記下流側筒部分８ｂの外周面の下側部分Ｆに当接する。前記下側円弧部６４は、前記係止部５６，５７，５９に係合する形状を有する。
【００３２】
また、爪部６１が形成された他方面（上流側面）Ｎ’には、抜け止め防止部材６０の下側円弧部６４と前記大径の開口部５５との係合を強固にするために、前記係止部５６，５７，５９に係合する形状の係合部７１ａを有する一対の係合片７１，７１が爪部６１を挟む形で形成されている。
【００３３】
而して、鍔部材５２の大径の開口部５５に下流側筒部分８ｂを挿通させた〔図８（Ｂ）参照〕後、下流側筒部分８ｂを、図８（Ｂ）に示すように、矢印Ｕで示す上方向に移動させることにより環状固定溝２９に小径の開口部５４を嵌め込む〔図６（Ｂ）参照〕ことにより、鍔部材５２を給水口部８に固定設置する。
【００３４】
続いて、開いている前記大径の開口部５５を覆うように下流側から前記抜け止め防止部材６０を前記大径の開口部５５に嵌め込むことにより前記抜け止め防止部材６０を鍔部材５２に係止する。これにより、ロックレバー２６が鍔部材５２に係止される接続時において鍔部材５２が前記小径の開口部５４から抜けるのを確実に防止できる。
【００３５】
【発明の効果】
この発明では、水栓の給水口部の外周面に給水流路の下流側から上流側に向かって、給水ホース側継手のロックボールが嵌まり込む環状ロック溝、抜け止め防止用の環状溝および当たり部を順次設ける一方、下流側から前記給水口部に着脱可能に嵌め込まれ、前記当たり部に当接する鍔部材と、この鍔部材に続いて下流側から前記給水口部に嵌め込まれ、前記抜け止め防止用の環状溝に嵌まり込み、それによって、前記ロックレバーが前記鍔部材に係止される接続時には前記鍔部材に当接した状態で前記鍔部材の前記給水口部からの抜けを防止しうる割りリングとを備えたので、給水ホースと水栓の給水口部を確実に接続できる効果がある。
【００３６】
また、この発明では、給水口部の外周面に給水流路の下流側から上流側に向かって、給水ホース側継手のロックボールが嵌まり込む環状ロック溝、環状固定溝を順次設ける一方、この環状固定溝に嵌まり込む小径の開口部および下流側から前記給水口部が挿通可能な大きさを有する大径の開口部よりなるダルマ状の開口を有する鍔部材を設け、この鍔部材に前記大径の開口部を介して前記給水口部を挿通させた後前記環状固定溝に前記小径の開口部を嵌め込んだ状態で、抜け止め防止部材を下流側から前記大径の開口部に嵌め込み可能に係止したので、前記ロックレバーが前記鍔部材に係止される接続時には前記鍔部材の前記小径の開口部からの抜け止めを確実に防止できる。
