【０００１】
【発明の属する技術分野】
本発明は、例えば洗濯機の給水口に取り付けた給水ホースに延長ホースを水密かつ着脱可能に接続するためのホース接合装置に関する。
【０００２】
【従来の技術】
周知の通り、全自動洗濯機等では、その給水口と水道栓とを給水ホースで直結するようにして使用している。そして、給水口と水道栓との距離が離れていて給水ホースだけでは届かない場合、給水ホースの先端の継手部に延長ホースのノズル部を水密かつ着脱可能に接続し、さらに延長ホースの先端の継手部を水道栓に取り付けて給水を行うようにしている。この時、ホース接合装置が給水ホースの継手部に延長ホースのノズル部を単に差し込むだけのものでは、給水ホースの先端部分に延長ホースを接続する際に差し込み方が不十分であると、給水ホースあるいは延長ホースに外力が加わった場合、差し込み方向とは逆方向に抜け外れてしまう虞があった。
【０００３】
このため、以下に図１０を参照して説明するようなホース接合装置が従来は用いられていた。すなわち、図１０はホース接合装置を説明するための図で、図１０（ａ）はノズル部を断面で示す延長ホースの側面図、図１０（ｂ）は給水ホースの側面図である。
【０００４】
図１０において、１は延長ホースで、延長ホース本体２の先端に水道栓に取り付けるための継手部３、他端にノズル部４を設けて構成されている。そして継手部３は、延長ホース本体２の先端に係止部材５を設けた継手６を装着して構成されており、係止部材５は、継手６の外周部分に突出する支持部７によって中間部が支持され、支持部７が弾性変形することによって延長ホース１の略軸方向を含む面内で揺動可能に形成されている。さらに係止部材５には先端に係止爪８が形成されている。一方、ノズル部４は、延長ホース本体２の他端に円形環状板でなる係合部材９とノズル１０を装着して構成されており、係合部材９は、ノズル１０の片端側を延長ホース本体２の他端部に圧入するようにして装着する際、両方の間に挟持するようにして取り付けられている。
【０００５】
また、１１は給水ホースで、給水ホース本体１２の先端に同じく水道栓に取り付けるための継手部３、他端に洗濯機の給水口に取り付けるための給水口ナット１３を設けて構成されている。なお、１４は延長ホース１及び給水ホース１１の両端に設けられた継手部３の継手６やノズル部４のノズル１０、給水口ナット１３の各ホース本体２，１２での保持を強化するためにかしめ固定されたキャップである。
【０００６】
このように構成されているので、給水ホース１１に延長ホース１を接続する場合には、給水ホース１１の先端の継手部３に、延長ホース１の他端のノズル部４を差し込むように嵌め合わせると共に、給水ホース１１の継手部３に設けられた係止部材５を、支持部７を弾性変形させながら延長ホース１の略軸方向を含む面内で先端の係止爪８を引き起こすように操作し、延長ホース１の円形環状板の係合部材９の外周部分に係止爪８を支持部７の弾性復元力によって引掛け、係止部材５を係合部材９に係合する。これにより継手部３にノズル部４が十分に差し込まれることになり、さらに係止部材５の係止爪８が係合部材９に引掛けられているので、給水ホース１１あるいは延長ホース１に外力が加わった場合でも、差し込み方向とは逆の方向には簡単に抜け外れてしまうことがない。
【０００７】
しかしながら上記の従来技術においては、継手部３へのノズル部４の差し込みが不十分になる虞は減少するものの、継手部３とノズル部４の接合部分が床面上に置かれていたりすると踏み付けられたり、また設置物の隙間に挟まれるなどしたりすることによって、係止部材５に直接外力が加わって係止爪８が係合部材９から外れてしまったり、係止部材５が破損等する虞があった。
【０００８】
【発明が解決しようとする課題】
上記のような状況に鑑みて本発明はなされたもので、ホース接合が十分に行えると共に、外力が加わっても係止部材が係合部材から簡単には外れてしまったりすることがないようにしたホース接合装置を提供することを目的とする。
【０００９】
【課題を解決するための手段】
本発明のホース接合装置は、ノズルが装着された第１のホースの端部に取り付けられた係合部材と、第２のホースの端部に装着された継手と、この継手に設けられた係止部材と、この係止部材に形成された係止爪とを備え、ノズルを継手に嵌挿すると共に、係止爪を係合部材に係合して第１のホースと第２のホースとを抜け止めし、水密かつ着脱可能に接合するホース接合装置であって、係合部材が、係合された係止部材の横ずれ防止構造を備えており、係止部材は継手に一体に形成されていることを特徴とするものであり、
さらに、横ずれ防止構造が、係合部材の外周部分に切り欠き形成された凹部でなり、該凹部の深さ寸法が係止部材の係合部分の高さ寸法より大きいものとなっていることを特徴とするものであり、
さらに、係合部材が、係合された係止部材の係合解除方向の動きを拘束する保持具を備えていることを特徴とするものであり、
さらに、係合部材が、係合された係止部材を覆う保持カバーを備えていることを特徴とするものであり、
さらに、横ずれ防止構造が、係合部材の外周部分に突出するよう係合孔が形成された凸部でなり、係合孔は係止部材が係合可能に貫通するように形成されたものであることを特徴とするものであり、
さらに、横ずれ防止構造が、係合部材の外周部分にホース接合方向に削設された溝部と、該溝部を横断するように設けられた係止部材の係止爪を係合する係合段部とを備えていることを特徴とするものであり、
さらに、溝部が、深溝と浅溝をホース接合方向に交差する方向に隣接して設けたものであって、係合段部が深溝を横断するように設けられていることを特徴とするものであり、
さらに、溝部は、係止爪を係合段部に係合させた際に係止部材が該溝部の外に出ない深さ寸法であることを特徴とするものである。
【００１０】
【発明の実施の形態】
以下、本発明の実施の形態を図面を参照して説明する。
【００１１】
先ず、第１の実施形態を図１及び図２により説明する。図１はホース接合装置を説明するための図で、図１（ａ）はノズル部を断面で示す延長ホースの側面図、図１（ｂ）は給水ホースの側面図であり、図２はホース接合装置の要部の斜視図である。
【００１２】
図１及び図２において、２１は第１のホースである延長ホースで、これは可撓性を有する耐圧ホースでなる延長ホース本体２２の先端に水道栓に取り付けるための継手部２３を設け、他端にノズル部２４を設けて構成されている。そして継手部２３は、延長ホース本体２２の先端に、係止部材２５を一体成形により設けた合成樹脂製の継手２６を装着して構成されている。また、係止部材２５は、継手２６の外周部分に外方に突出するように形成された板状の支持部２７によって中間部が支持され、支持部２７が弾性変形することによって延長ホース２１の略軸方向を含む面内で揺動可能に設けられている。さらに係止部材２５の先端には同じく係止爪２８が一体成形により形成されている。
【００１３】
一方、ノズル部２４は、延長ホース本体２２の他端に円形環状板でなる係合部材２９とノズル３０を装着して構成されている。ノズル３０は中間部に中間鍔部３１を有し、片端側には延長ホース本体２２に圧入するように装着した際に抜け止まるように形成した抜け止め段部３２を備え、さらに他端側には、後述する給水ホース３３に接続する際に給水ホース３３の継手２６が水密かつ着脱可能に接合されるよう形成した嵌合段部３４を備えている。
【００１４】
また、係合部材２９は、円形環状板の外周部分に係止部材２５の横ずれ防止構造である凹部３５が少なくとも１か所切り欠き形成されており、その形状寸法は給水ホース３３の継手２６に設けられた係止部材２５が係合した際に凹部３５から突出しない寸法となっている。すなわち、凹部３５の深さ寸法は係止部材２５の係合部分の高さ寸法より大きいものとなっている。そして係合部材２９は、ノズル３０の片端側の抜け止め段部３２を延長ホース本体２２の他端部に圧入するようにして装着する際、抜け止め段部３２を係合部材２９の内径部３６に貫通させた状態で、延長ホース本体２２の他端面とノズル３０の中間鍔部３１との間に挟持するようにして取り付けられている。
【００１５】
また、第２のホースである給水ホース３３は、可撓性を有する耐圧ホースでなる給水ホース本体３７の先端に、延長ホース２１に設けられているものと同構成の水道栓に取り付けるための継手部２３を設け、他端に洗濯機の給水口に取り付けるための給水口ナット３８を設けて構成されている。なお、３９は延長ホース２１及び給水ホース３３の両端に設けられた継手部２３の継手２６やノズル部２４のノズル３０、給水口ナット３８の各ホース本体２２，３７での保持を強化するためにかしめ固定されたキャップである。また、４０ａ，４０ｂは係止部材２５に突出するように設けられた引き起こし操作範囲を規制する規制突起および規制片である。
【００１６】
このように構成されているので、給水ホース３３に延長ホース２１を接続する場合には、給水ホース３３の先端に設けられた継手部２３の継手２６に、延長ホース２１の他端に設けられたノズル部２４のノズル３０を差し込むように嵌め合わせると共に、給水ホース３３の継手部２３に設けられた係止部材２５を、支持部２７を弾性変形させながら延長ホース２１の略軸方向を含む面内で、規制突起４０ａと規制片４０ｂにより動きが規制される範囲内で先端の係止爪２８を引き起こすように後端側を操作し、延長ホース２１の円形環状板の係合部材２９の外周部分に形成された凹部３５内に係止部材２５を嵌め合わせ、さらに係止爪２８を支持部２７の弾性復元力によって凹部３５の底部分に引掛け、係止部材２５を係合部材２９に係合する。これにより継手部２３の継手２６にノズル部２４のノズル３０が十分に差し込まれる。
【００１７】
また、この時、係止部材２５は、係合部材２９の凹部３５内に外周部分より外方に突出しないように嵌め合わされ、さらに先端の係止爪２８が凹部３５の底部分に引掛けられた状態になるため、給水ホース３３あるいは延長ホース２１に外力が加わった場合でも、差し込み方向とは逆の方向には簡単に抜け外れてしまうことがなくなる。また継手部２３とノズル部２４の接合部分が床面上に置かれていて踏み付けられたり、設置物の隙間に挟まれるなどしたりしても、凹部３５内に嵌め合わされていて横方向への動きが規制されているので、係止部材２５は外力を受けて横方向にずれ動くことがなくなる。これにより係止爪２８が係合部材２９から外れてしまうことがなく、係止部材２５が変形したり、破損したりする虞が低減する。
【００１８】
なお、給水ホース３３と延長ホース２１の接続を解除する場合には、再び係止部材２５を操作し、支持部２７を弾性変形させながら先端の係止爪２８を引き起こして係合部材２９の凹部３５の底部分から外し、この状態で継手２６からノズル３０を差し込み方向とは逆の方向に引き抜くことによって、給水ホース３３と延長ホース２１の接続は解除される。
【００１９】
次に、第２の実施形態を図３により説明する。図３はホース接合装置の要部の斜視図である。なお、第１の実施形態と同一部分には同一符号を付して説明を省略し、異なる本実施形態の構成について説明する。
【００２０】
図３において、４１は第１のホースである延長ホースで、延長ホース本体２２の先端に給水ホース３３と同構成の図示しない継手部を設け、他端にノズル部４２を設けて構成されている。この延長ホース４１は、ノズル部４２の軸方向外側を給水ホース３３の継手部２３に接合することによって給水ホース３３と接続されるものである。そして延長ホース４１に設けられたノズル部４２は、延長ホース本体２２の他端に略円形環状板でなる係合部材４３と図示しないノズルを装着して構成されている。係合部材４３は、係合された継手２６の係止部材２５の横ずれ防止構造である係合孔４４を有する凸部４５が、その略円形環状板の外周部分に少なくとも１か所突出するように形成されており、凸部４５に形成された係合孔４４は係止部材２５が係合可能に貫通するような形状に形成されている。また係合部材４３は、ノズルの片端側を延長ホース本体２２の他端部に圧入するようにして装着する際、ノズルの片端側を係合部材４３の内径部分に貫通させた状態で、延長ホース本体２２の他端面とノズルの図示しない中間鍔部との間に挟持するようにして取り付けられている。
【００２１】
このように構成されているので、給水ホース３３に延長ホース４１を接続する場合には、給水ホース３３の先端に設けられた継手部２３の継手２６に、延長ホース４１の他端に設けられたノズル部４２のノズルを差し込むように嵌め合わせると共に、差し込む際に給水ホース３３の継手部２３に設けられた係止部材２５を、支持部２７を弾性変形させながら延長ホース４１の略軸方向を含む面内で先端の係止爪２８を引き起こすように後端側を操作しながら、係止部材２５を延長ホース４１の係合部材４３に形成された凸部４５の係合孔４４に貫通させ、その後に係止爪２８を支持部２７の弾性復元力によって係合孔４４の縁部分に引掛け、係止部材２５を係合部材４３に係合する。これにより継手部２３の継手２６にノズル部４２のノズルが十分に差し込まれる。
【００２２】
また、この時、係止部材２５は、係合部材４３の係合孔４４内に、凸部４５の逆Ｕ字状のアーチで外側が防護されるようにして嵌め合わされ、さらに先端の係止爪２８が係合孔４４の縁部分に引掛けられた状態になるため、給水ホース３３あるいは延長ホース４１に外力が加わった場合でも、差し込み方向とは逆の方向には簡単に抜け外れてしまうことがなくなる。また継手部２３とノズル部４２の接合部分が床面上に置かれていて踏み付けられたり、設置物の隙間に挟まれるなどしたりしても、係止部材２５は係合孔４４を有する凸部４５に嵌め合わされていて横方向への動きが規制されているので、係止部材２５は外力を受けて横方向にずれ動くことがなくなる。これにより係止爪２８が係合部材４３から外れてしまうことがなく、係止部材２５が変形したり、破損したりする虞が低減する。
【００２３】
なお、給水ホース３３と延長ホース４１の接続を解除する場合には、再び係止部材２５を操作し、支持部２７を弾性変形させながら先端の係止爪２８を引き起こして係合部材４３の係合孔４４の縁部分から外し、この状態で継手２６からノズルを差し込み方向とは逆の方向に引き抜くことによって、給水ホース３３と延長ホース４１の接続は解除される。
【００２４】
次に、第３の実施形態を図４により説明する。図４はホース接合装置の要部の斜視図である。なお、第１の実施形態と同一部分には同一符号を付して説明を省略し、異なる本実施形態の構成について説明する。
【００２５】
図４において、５１は第１のホースである延長ホースで、延長ホース本体２２の先端に給水ホース３３と同構成の図示しない継手部を設け、他端にノズル部５２を設けて構成されている。この延長ホース５１は、ノズル部５２の軸方向外側を第２のホースである給水ホース３３の継手部２３に接合することによって給水ホース３３と接続されるものである。そして延長ホース５１に設けられたノズル部５２は、延長ホース本体２２の他端に、外形状が略円錐台状の筒状体でなる係合部材５３を径大部が軸方向外方側となるように装着すると共に、図示しないノズルを装着して構成されている。係合部材５３は、係合された継手２６の係止部材２５の横ずれ防止構造である軸方向の溝部５４が、その筒状体の外面部分に少なくとも１か所形成されており、溝部５４には軸方向外側部分に横断するように係止部材２５の係止爪２８が引掛けられ係合する係合段部５５が設けられている。
【００２６】
また、溝部５４の形状寸法は、係合段部５５に係止爪２８を引掛け係合させた際に溝部５４から係止部材２５が突出しない寸法となっている。すなわち、溝部５４の深さ寸法は係止部材２５の係合部分の高さ寸法より大きいものとなっている。また係合部材５３は、ノズルの片端側を延長ホース本体２２の他端部に圧入するようにして装着する際、ノズルの片端側を係合部材５３の内径部分に貫通させた状態で、延長ホース本体２２の他端面とノズルの図示しない中間鍔部との間に挟持するようにして取り付けられている。
【００２７】
このように構成されているので、給水ホース３３に延長ホース５１を接続する場合には、給水ホース３３の先端に設けられた継手部２３の継手２６に、延長ホース５１の他端に設けられたノズル部５２のノズルを実線矢印Ｘで示す方向に差し込むように嵌め合わせると共に、差し込む際に給水ホース３３の継手部２３に設けられた係止部材２５を、支持部２７を弾性変形させながら延長ホース５１の略軸方向を含む面内で先端の係止爪２８を引き起こすように後端側を操作しながら、係止部材２５を延長ホース５１の係合部材５３に形成された溝部５４に嵌め合わせ、その後に係止爪２８を支持部２７の弾性復元力によって係合段部５５に引掛け、係止部材２５を係合部材５３に係合する。これにより継手部２３の継手２６にノズル部５２のノズルが十分に差し込まれる。
【００２８】
また、この時、係止部材２５は、係合部材５３の溝部５４内に外周面部分より外方に突出しないように嵌め合わされ、さらに先端の係止爪２８が係合段部５５に引掛けられた状態になるため、給水ホース３３あるいは延長ホース５１に外力が加わった場合でも、差し込み方向とは逆の方向には簡単に抜け外れてしまうことがなくなる。また継手部２３とノズル部５２の接合部分が床面上に置かれていて踏み付けられたり、設置物の隙間に挟まれるなどしたりしても、係止部材２５は溝部５４内に嵌め合わされていて横方向への動きが規制されているので、外力を受けて横方向にずれ動くことがなくなる。これにより係止爪２８が係合部材５３から外れてしまうことがなく、係止部材２５が変形したり、破損したりする虞が低減する。
【００２９】
なお、給水ホース３３と延長ホース５１の接続を解除する場合には、再び係止部材２５を操作し、支持部２７を弾性変形させながら先端の係止爪２８を引き起こして係合部材５３の溝部５４の係合段部５５から外し、この状態で継手２６からノズルを差し込み方向とは逆の方向に引き抜くことによって、給水ホース３３と延長ホース５１の接続は解除される。
【００３０】
次に、第４の実施形態を図５により説明する。図５はホース接合装置の要部の斜視図である。なお、第１の実施形態と同一部分には同一符号を付して説明を省略し、異なる本実施形態の構成について説明する。
【００３１】
図５において、６１は第１のホースである延長ホースで、延長ホース本体２２の先端に給水ホース３３と同構成の図示しない継手部を設け、他端にノズル部６２を設けて構成されている。この延長ホース６１は、ノズル部６２の軸方向外側を第２のホースである給水ホース３３の継手部２３に接合することによって給水ホース３３と接続されるものである。そして延長ホース６１に設けられたノズル部６２は、延長ホース本体２２の他端に、外形状が略円錐台状の筒状体でなる係合部材６３を径大部が軸方向外方側となるように装着すると共に、図示しないノズルを装着して構成されている。また係合部材６３は、係合された継手２６の係止部材２５の横ずれ防止構造である軸方向の溝部６４が、その筒状体の外面部分に少なくとも１か所形成されている。溝部６４は浅溝６５と、この浅溝６５に周方向に隣接して削設された深溝６６とを有し、深溝６６には軸方向外側部分に横断するように係止部材２５の係止爪２８が引掛けられ係合する係合段部６７が設けられている。
【００３２】
また、溝部６４の形状寸法は、浅溝６５の深さ寸法については、ノズル部６２と継手部２３とを接合する際に引き起こした係止爪２８が、通過可能な深さとなっており、深溝６６の深さ寸法については、係合段部６７に係止爪２８を引掛け係合させた際に深溝６６及び溝部６４から係止部材２５が突出しない寸法、すなわち、係止部材２５の係合部分の高さ寸法より大きいものとなっている。さらに係合段部６７の高さ寸法は、係止部材２５の動きが規制突起４０ａと規制片４０ｂにより規制されるまで引き起こした係止爪２８が、乗り越えない高さとなっている。また係合部材６３は、ノズルの片端側を延長ホース本体２２の他端部に圧入するようにして装着する際、ノズルの片端側を係合部材６３の内径部分に貫通させた状態で、延長ホース本体２２の他端面とノズルの図示しない中間鍔部との間に挟持するようにして取り付けられている。
【００３３】
このように構成されているので、給水ホース３３に延長ホース６１を接続する場合には、給水ホース３３の先端に設けられた継手部２３の継手２６に、延長ホース６１の他端に設けられたノズル部６２のノズルを実線矢印Ｘで示す方向に差し込むように嵌め合わせると共に、差し込む際に給水ホース３３の継手部２３に設けられた係止部材２５を、支持部２７を弾性変形させながら延長ホース６１の略軸方向を含む面内で先端の係止爪２８を引き起こすように後端側を操作し、さらに、係止部材２５を延長ホース６１の係合部材６３に形成された溝部６４の浅溝６５に軸方向に動かして嵌め合わせ、続いて実線矢印Ｙで示すように周方向に回動することで係止部材２５の係止爪２８が深溝６６内に嵌め合わされるようにする。その後に係止爪２８を支持部２７の弾性復元力によって係合段部６７に引掛け、係止部材２５を係合部材６３に係合する。これにより継手部２３の継手２６にノズル部６２のノズルが十分に差し込まれる。
【００３４】
また、この時、係止部材２５は、係合部材６３の溝部６４内に外周面部分より外方に突出しないように嵌め合わされ、さらに先端の係止爪２８が軸方向と周方向の２つの動きを組み合わせた形で係合段部６７に引掛けられた状態になるため、給水ホース３３あるいは延長ホース６１に外力が加わった場合でも、差し込み方向とは逆の方向には簡単に抜け外れてしまうことがなくなる。また継手部２３とノズル部６２の接合部分が床面上に置かれていて踏み付けられたり、設置物の隙間に挟まれるなどしたりしても、係止部材２５は溝部６４内に嵌め合わされていて横方向への動きが規制されているので、外力を受けて横方向にずれ動くことがなくなる。これにより係止爪２８が係合部材５３から外れてしまうことがなく、係止部材２５が変形したり、破損したりする虞が低減する。
【００３５】
なお、給水ホース３３と延長ホース６１の接続を解除する場合には、再び係止部材２５を操作し、支持部２７を弾性変形させながら先端の係止爪２８を引き起こして係合部材６３の溝部６４の係合段部６７から外し、続いてノズル部６２を周方向に回動して係止爪２８が深溝６６から浅溝６５に来るようにする。そして、この状態で継手２６からノズルを差し込み方向とは逆の方向に引き抜くことによって、給水ホース３３と延長ホース６１の接続は解除される。
【００３６】
次に、第５の実施形態を図６及び図７により説明する。図６はホース接合装置の要部の斜視図であり、図７はノズル部の斜視図である。なお、第１の実施形態と同一部分には同一符号を付して説明を省略し、異なる本実施形態の構成について説明する。
【００３７】
図６及び図７において、７１は第１のホースである延長ホース、７２は第２のホースである給水ホースで、延長ホース本体２２及び給水ホース本体３７の先端には継手部７３が設けられている。なお、延長ホース本体２２の継手部７３については図示してない。また、延長ホース本体２２の他端にはノズル部７４が設けられ、給水ホース本体３７の他端には洗濯機の給水口に取り付けるための図示しない給水口ナットが設けられており、延長ホース７１は、ノズル部７４の軸方向外側を給水ホース７２の継手部７３に接合することによって、給水ホース７２と接続される。そして給水ホース７２の継手部７３は、給水ホース本体３７の先端に、係止部材７５を一体成形により設けた合成樹脂製の継手７６を装着して構成されている。また、係止部材７５は、継手７６の外周部分に外方に突出するように形成された板状の支持部２７によって中間部が支持され、支持部２７が弾性変形することによって給水ホース７２の略軸方向を含む面内で揺動可能に設けられている。さらに係止部材７５の先端には係止爪２８が同じく一体成形により形成され、後端には保持凹部７７が形成されている。
【００３８】
一方、延長ホース７１に設けられたノズル部７４は、延長ホース本体２２の他端に略円形環状板でなる係合部材７８と図示しないノズルを装着して構成されている。係合部材７８は、係合された継手７６の係止部材７５の横ずれ防止構造である凹部７９と保持具８０とが、その略円形環状板の外周部分に少なくとも１か所に設けられている。そして凹部７９の形状寸法は、給水ホース７２の継手７６に設けられた係止部材７５が係合した際に凹部７９から突出しない寸法となっている。すなわち、凹部７９の深さ寸法は係止部材７５の係合部分の高さ寸法より大きいものとなっている。また、保持具８０は、例えば鋼棒材を曲折して形成したもので、略Ｕ字状の保持部８１と両先端に支軸８２を有し、支軸８２を係合部材７８の延長ホース本体２２端側の面に突設した軸受け部８３に、保持部８１が凹部７９内で矢印Ｒで示すように回動可能に支持されている。そして係合部材７８は、ノズルの片端側を延長ホース本体２２の他端部に圧入するようにして装着する際、ノズルの片端側を係合部材７８の内径部分に貫通させた状態で、延長ホース本体２２の他端面とノズルの図示しない中間鍔部との間に挟持するようにして取り付けられている。

このように構成されているので、給水ホース７２に延長ホース７１を接続する場合には、給水ホース７２の先端に設けられた継手部７３の継手７６に、延長ホース７１の他端に設けられたノズル部７４のノズルを差し込むように嵌め合わせると共に、給水ホース７２の継手部７３に設けられた係止部材７５を、支持部２７を弾性変形させながら延長ホース７１の略軸方向を含む面内で、規制突起４０ａと規制片４０ｂにより動きが規制される範囲内で先端の係止爪２８を引き起こすように後端側を操作し、延長ホース７１の円形環状板の係合部材７８の外周部分に形成された凹部７９内に係止部材７５を嵌め合わせ、さらに係止爪２８を支持部２７の弾性復元力によって凹部７９の底部分に引掛け、係止部材７５を係合部材７８に係合する。またさらに、保持具８０を支軸８２を中心に係止部材７５の後端側に回動し、係止部材７５の後端に形成された保持凹部７７に嵌め合わせ、保持具８０によって、揺動可能に設けられた係止部材７５を動かないよう拘束する。これにより継手部７３の継手７６にノズル部７４のノズルが十分に差し込まれた状態になる。
【００４０】
また、この時、係止部材７５は、係合部材７８の凹部７９内に外周部分より外方に突出しないように嵌め合わされ、さらに先端の係止爪２８が凹部７９の底部分に引掛けられた状態になり、保持具８０で係止部材７５が拘束されるため、給水ホース７２あるいは延長ホース７１に外力が加わった場合でも、差し込み方向とは逆の方向には簡単に抜け外れてしまうことがなくなる。また継手部７３とノズル部７４の接合部分が床面上に置かれていて踏み付けられたり、設置物の隙間に挟まれるなどしたりしても、係止部材７５は凹部７９内に嵌め合わされていて横方向への動きが規制され、さらに保持具８０によって動かないよう拘束されているので、外力を受けて横方向にずれ動くことがなくなる。これにより係止爪２８が係合部材７８から外れてしまうことがなく、係止部材７５が変形したり、破損したりする虞が低減する。
【００４１】
なお、給水ホース７２と延長ホース７１の接続を解除する場合には、保持具８０を拘束を解除するように回動し、係止部材７５を操作し、支持部２７を弾性変形させながら先端の係止爪２８を引き起こして係合部材７８の凹部７９の底部分から外す。そして、この状態で継手７６からノズルを差し込み方向とは逆の方向に引き抜くことによって、給水ホース７２と延長ホース７１の接続は解除される。

係合部材９３は、係合された継手２６の係止部材２５の横ずれ防止構造である凹部７９と保持カバー９４とが、その略円形環状板の外周部分に少なくとも１か所に設けられている。そして凹部７９の形状寸法は、給水ホース３３の継手２６に設けられた係止部材２５が係合した際に凹部７９から突出しない寸法となっている。すなわち、凹部７９の深さ寸法は係止部材２５の係合部分の高さ寸法より大きいものとなっている。また、保持カバー９４は、合成樹脂製の係止部材２５を覆う形状のカバー体９５と、カバー体９５の片端部の両側面に突設された支軸９６を有し、支軸９６を係合部材９３の延長ホース本体２２端側の面に突設した軸受け部８３に、カバー体９５が凹部７９内で矢印Ｒで示すように回動可能に支持されている。そして係合部材９３は、ノズルの片端側を延長ホース本体２２の他端部に圧入するようにして装着する際、ノズルの片端側を係合部材９３の内径部分に貫通させた状態で、延長ホース本体２２の他端面とノズルの図示しない中間鍔部との間に挟持するようにして取り付けられている。
【００４５】
このように構成されているので、給水ホース３３に延長ホース９１を接続する場合には、給水ホース３３の先端に設けられた継手部２３の継手２６に、延長ホース９１の他端に設けられたノズル部９２のノズルを差し込むように嵌め合わせると共に、給水ホース３３の継手部２３に設けられた係止部材２５を、支持部２７を弾性変形させながら延長ホース９１の略軸方向を含む面内で、規制突起４０ａと規制片４０ｂにより動きが規制される範囲内で先端の係止爪２８を引き起こすように後端側を操作し、延長ホース９１の係合部材９３の外周部分に形成された凹部７９内に係止部材２５を嵌め合わせ、さらに係止爪２８を支持部２７の弾性復元力によって凹部７９の底部分に引掛け、係止部材２５を係合部材９３に係合する。またさらに、保持カバー９４を支軸９６を中心に係止部材２５を覆うように回動し、保持カバー９４で覆うことにより係止部材２５を動かないよう拘束する。この結果、継手部２３の継手２６にノズル部９２のノズルが十分に差し込まれた状態になる。
【００４６】
また、この時、係止部材２５は、係合部材９２の凹部７９内に外周部分より外方に突出しないように嵌め合わされ、さらに先端の係止爪２８が凹部７９の底部分に引掛けられた状態になり、保持カバー９４で係止部材２５が覆われることになるため、給水ホース３３あるいは延長ホース９１に外力が加わった場合でも、差し込み方向とは逆の方向には簡単に抜け外れてしまうことがなくなる。また継手部２３とノズル部９２の接合部分が床面上に置かれていて踏み付けられたり、設置物の隙間に挟まれるなどしたりしても、係止部材２５は凹部７９内に嵌め合わされていて横方向への動きが規制され、さらに保持カバー９４によって動かないよう覆われてしまっているので、外力を受けて横方向にずれ動くことがなくなる。これにより係止爪２８が係合部材９３から外れてしまうことがなく、係止部材２５が変形したり、破損したりする虞が低減する。

BACKGROUND OF THE INVENTION
The present invention relates to a hose joining device for connecting an extension hose in a watertight and detachable manner to a water supply hose attached to a water supply port of a washing machine, for example.
[0002]
[Prior art]
As is well known, in a fully automatic washing machine or the like, the water supply port and the water tap are directly connected by a water supply hose. If the distance between the water supply port and the water tap is too far to reach by the water supply hose alone, connect the nozzle part of the extension hose to the joint at the tip of the water supply hose in a watertight and detachable manner. The joint is attached to a water tap to supply water. At this time, if the hose joining device simply inserts the nozzle part of the extension hose into the joint part of the water supply hose, when the extension hose is connected to the tip of the water supply hose, the insertion method is insufficient. Alternatively, when an external force is applied to the extension hose, the extension hose may come off in the direction opposite to the insertion direction.
[0003]
For this reason, a hose joining device as will be described below with reference to FIG. 10 has been conventionally used. That is, FIG. 10 is a view for explaining the hose joining device, FIG. 10 (a) is a side view of the extension hose showing the nozzle portion in cross section, and FIG. 10 (b) is a side view of the water supply hose.
[0004]
In FIG. 10, reference numeral 1 denotes an extension hose, which is configured by providing a joint part 3 for attaching to a water tap at the tip of the extension hose body 2 and a nozzle part 4 at the other end. And the joint part 3 is comprised by mounting | wearing with the joint 6 which provided the latching member 5 in the front-end | tip of the extension hose main body 2, and the latching member 5 is intermediate | middle by the support part 7 which protrudes in the outer peripheral part of the joint 6. The support portion 7 is supported, and the support portion 7 is elastically deformed to be swingable in a plane including the substantially axial direction of the extension hose 1. Furthermore, a locking claw 8 is formed at the tip of the locking member 5. On the other hand, the nozzle portion 4 is configured by mounting an engagement member 9 made of a circular annular plate and a nozzle 10 on the other end of the extension hose body 2, and the engagement member 9 extends from one end of the nozzle 10 to the extension hose. When it is attached so as to be press-fitted into the other end of the main body 2, it is attached so as to be sandwiched between the two.
[0005]
Reference numeral 11 denotes a water supply hose, which has a water supply hose body 12 provided with a joint portion 3 for attachment to a water tap and a water supply nut 13 for attachment to a water supply port of a washing machine at the other end. In addition, 14 strengthens the holding | maintenance in each hose main body 2 and 12 of the joint 6 of the joint part 3 provided in the both ends of the extension hose 1 and the water supply hose 11, the nozzle 10 of the nozzle part 4, and the water supply nut 13. It is a cap fixed by caulking.
[0006]
Since it is comprised in this way, when connecting the extension hose 1 to the water supply hose 11, it fits so that the nozzle part 4 of the other end of the extension hose 1 may be inserted in the joint part 3 of the front end of the water supply hose 11. At the same time, the locking member 5 provided in the joint portion 3 of the water supply hose 11 is operated so as to cause the locking claw 8 at the tip in the plane including the substantially axial direction of the extension hose 1 while elastically deforming the support portion 7. Then, the locking claw 8 is hooked on the outer peripheral portion of the engagement member 9 of the circular annular plate of the extension hose 1 by the elastic restoring force of the support portion 7, and the locking member 5 is engaged with the engagement member 9. As a result, the nozzle portion 4 is sufficiently inserted into the joint portion 3 and the engaging claw 8 of the engaging member 5 is hooked on the engaging member 9, so that an external force is applied to the water supply hose 11 or the extension hose 1. Even if is added, it will not easily come off in the direction opposite to the insertion direction.
[0007]
However, in the above prior art, although the possibility that the nozzle portion 4 is insufficiently inserted into the joint portion 3 is reduced, the joint portion 3 and the nozzle portion 4 are stepped on when they are placed on the floor surface. Or by being caught in a gap between the installed objects, an external force is directly applied to the locking member 5 and the locking claw 8 is detached from the engaging member 9, or the locking member 5 is damaged. There was a fear.
[0008]
[Problems to be solved by the invention]
The present invention has been made in view of the above situation so that the hose can be sufficiently joined and the locking member is not easily detached from the engaging member even when an external force is applied. An object of the present invention is to provide a hose joining apparatus.

FIG. 1 is a view for explaining a hose joining device, FIG. 1 (a) is a side view of an extension hose showing a nozzle section in section, FIG. 1 (b) is a side view of a water supply hose, and FIG. 2 is a hose. It is a perspective view of the principal part of a joining device.
[0012]
1 and 2, 21 is an extension hose which is a first hose, which is provided with a joint portion 23 for attaching to a water tap at the tip of an extension hose body 22 which is a flexible pressure-resistant hose. A nozzle portion 24 is provided at the end. And the joint part 23 is comprised by mounting | wearing the front-end | tip of the extension hose main body 22 with the synthetic resin joint 26 which provided the latching member 25 by integral molding. Further, the locking member 25 is supported at its intermediate portion by a plate-like support portion 27 formed so as to protrude outwardly on the outer peripheral portion of the joint 26, and the support portion 27 is elastically deformed, whereby the extension hose 21. It is provided so as to be able to swing within a plane including the substantially axial direction. Further, a locking claw 28 is also formed at the tip of the locking member 25 by integral molding.
[0013]
On the other hand, the nozzle portion 24 is configured by mounting an engagement member 29 formed of a circular annular plate and a nozzle 30 on the other end of the extension hose body 22. The nozzle 30 has an intermediate flange portion 31 at the intermediate portion, and is provided with a retaining step portion 32 formed so as to be prevented from coming off when mounted so as to be press-fitted into the extension hose body 22 on one end side, and further on the other end side. Is provided with a fitting step 34 formed so that the joint 26 of the water supply hose 33 is joined in a watertight and detachable manner when connected to a water supply hose 33 described later.
[0014]
Further, the engaging member 29 is formed with at least one recess 35 which is a structure for preventing the lateral displacement of the locking member 25 in the outer peripheral portion of the circular annular plate, and the shape dimension thereof is the same as that of the joint 26 of the water supply hose 33. When the provided locking member 25 is engaged, the dimension does not protrude from the recess 35. That is, the depth dimension of the recess 35 is larger than the height dimension of the engaging portion of the locking member 25. When the engagement member 29 is mounted so that the stopper step 32 on one end side of the nozzle 30 is press-fitted into the other end of the extension hose body 22, the stopper step 32 is connected to the inner diameter portion of the engagement member 29. In a state of passing through 36, it is attached so as to be sandwiched between the other end surface of the extension hose body 22 and the intermediate flange 31 of the nozzle 30.
[0015]
Moreover, the water supply hose 33 which is a 2nd hose is a joint for attaching to the water tap of the same structure as what is provided in the extension hose 21 at the front-end | tip of the water supply hose main body 37 which consists of a flexible pressure hose. A portion 23 is provided, and a water supply nut 38 for attaching to the water supply port of the washing machine is provided at the other end. In addition, 39 strengthens the holding | maintenance in each hose main body 22 and 37 of the joint 26 of the joint part 23 provided in the both ends of the extension hose 21 and the water supply hose 33, the nozzle 30 of the nozzle part 24, and the water supply port nut 38. It is a cap fixed by caulking. Reference numerals 40a and 40b denote restricting protrusions and restricting pieces for restricting the operation range that is caused to protrude from the locking member 25.
[0016]
With this configuration, when the extension hose 21 is connected to the water supply hose 33, the joint 26 of the joint portion 23 provided at the tip of the water supply hose 33 is provided at the other end of the extension hose 21. In-plane including the substantially axial direction of the extension hose 21 while fitting the nozzle 30 of the nozzle part 24 so as to be inserted, and engaging the locking member 25 provided on the joint part 23 of the water supply hose 33 while elastically deforming the support part 27 Then, the rear end side is operated so as to cause the locking claw 28 at the front end within a range in which the movement is restricted by the restriction protrusion 40a and the restriction piece 40b, and the outer peripheral portion of the engagement member 29 of the circular annular plate of the extension hose 21 The engaging member 25 is fitted into the recessed portion 35 formed in the inner surface, and the engaging claw 28 is hooked on the bottom portion of the recessed portion 35 by the elastic restoring force of the support portion 27, and the engaging member 25 is engaged with the engaging member 29. Combine . Thereby, the nozzle 30 of the nozzle part 24 is fully inserted into the joint 26 of the joint part 23.
[0017]
At this time, the locking member 25 is fitted in the recess 35 of the engagement member 29 so as not to protrude outward from the outer peripheral portion, and the locking claw 28 at the tip is hooked on the bottom portion of the recess 35. Therefore, even when an external force is applied to the water supply hose 33 or the extension hose 21, it will not easily come off in the direction opposite to the insertion direction. Even if the joint part 23 and the nozzle part 24 are placed on the floor surface and stepped on, or sandwiched between the gaps in the installation object, the joint part 23 and the nozzle part 24 are fitted in the recesses 35 so as to extend in the lateral direction. Since the movement is restricted, the locking member 25 does not move laterally by receiving an external force. Thereby, the latching claw 28 does not come off from the engagement member 29, and the possibility that the latching member 25 is deformed or damaged is reduced.
[0018]
When the connection between the water supply hose 33 and the extension hose 21 is to be released, the locking member 25 is operated again to cause the locking claw 28 at the distal end while elastically deforming the support portion 27 to cause the concave portion of the engagement member 29 to be depressed. The connection between the water supply hose 33 and the extension hose 21 is released by removing the nozzle 30 from the bottom portion 35 and withdrawing the nozzle 30 from the joint 26 in the direction opposite to the insertion direction.
[0019]
Next, a second embodiment will be described with reference to FIG. FIG. 3 is a perspective view of a main part of the hose joining apparatus. In addition, the same code | symbol is attached | subjected to the same part as 1st Embodiment, description is abbreviate | omitted, and the structure of this different embodiment is demonstrated.
[0020]
In FIG. 3, reference numeral 41 denotes an extension hose that is a first hose, which is configured by providing a joint portion (not shown) having the same configuration as the water supply hose 33 at the tip of the extension hose body 22 and providing a nozzle portion 42 at the other end. . The extension hose 41 is connected to the water supply hose 33 by joining the outer side in the axial direction of the nozzle portion 42 to the joint portion 23 of the water supply hose 33. The nozzle portion 42 provided in the extension hose 41 is configured by mounting an engagement member 43 formed of a substantially circular annular plate and a nozzle (not shown) on the other end of the extension hose body 22. The engaging member 43 has at least one protrusion 45 having an engaging hole 44 which is a structure for preventing the lateral displacement of the locking member 25 of the engaged joint 26 so as to protrude from the outer peripheral portion of the substantially circular annular plate. The engagement hole 44 formed in the convex portion 45 is formed in a shape that allows the locking member 25 to be engaged therethrough. Further, when the engagement member 43 is mounted so that one end side of the nozzle is press-fitted into the other end portion of the extension hose body 22, the engagement member 43 is extended in a state where the one end side of the nozzle is passed through the inner diameter portion of the engagement member 43. The hose body 22 is attached so as to be sandwiched between the other end face of the hose body 22 and an intermediate flange (not shown) of the nozzle.
[0021]
Since it is configured in this manner, when connecting the extension hose 41 to the water supply hose 33, the joint 26 of the joint portion 23 provided at the tip of the water supply hose 33 is provided at the other end of the extension hose 41. The nozzle part 42 is fitted so that the nozzle is inserted, and the locking member 25 provided on the joint part 23 of the water supply hose 33 is inserted into the nozzle part 42 and includes the substantially axial direction of the extension hose 41 while elastically deforming the support part 27. While operating the rear end side to cause the front-end locking claw 28 in the plane, the locking member 25 is passed through the engagement hole 44 of the convex portion 45 formed in the engagement member 43 of the extension hose 41, Thereafter, the locking claw 28 is hooked on the edge portion of the engagement hole 44 by the elastic restoring force of the support portion 27, and the locking member 25 is engaged with the engagement member 43. Thereby, the nozzle of the nozzle part 42 is fully inserted in the joint 26 of the joint part 23.
[0022]
At this time, the locking member 25 is fitted into the engagement hole 44 of the engagement member 43 so that the outside is protected by the inverted U-shaped arch of the convex portion 45, and the distal end is locked. Since the claw 28 is hooked on the edge portion of the engagement hole 44, even when an external force is applied to the water supply hose 33 or the extension hose 41, the claw 28 is easily detached in the direction opposite to the insertion direction. Nothing will happen. Further, even when the joint portion 23 and the nozzle portion 42 are placed on the floor surface and are stepped on, or are caught in a gap between the installation objects, the locking member 25 has a convex shape having an engagement hole 44. Since the movement in the lateral direction is restricted by being fitted to the portion 45, the locking member 25 does not move in the lateral direction due to the external force. Thereby, the latching claw 28 does not come off from the engagement member 43, and the possibility that the latching member 25 is deformed or damaged is reduced.
[0023]
When the connection between the water supply hose 33 and the extension hose 41 is released, the locking member 25 is operated again, and the locking claw 28 at the tip is raised while elastically deforming the support portion 27 to engage the engaging member 43. The connection between the water supply hose 33 and the extension hose 41 is released by removing the nozzle from the edge portion of the joint hole 44 and pulling out the nozzle from the joint 26 in this state in the direction opposite to the insertion direction.
[0024]
Next, a third embodiment will be described with reference to FIG. FIG. 4 is a perspective view of a main part of the hose joining apparatus. In addition, the same code | symbol is attached | subjected to the same part as 1st Embodiment, description is abbreviate | omitted, and the structure of this different embodiment is demonstrated.
[0025]
