【発明の属する技術分野】
本発明は、窓ガラスのガラスと網戸の網の両方を清掃するための清掃装置に関するものである。
【０００２】
【従来の技術】
従来より、図８に示すような清掃装置が提案されている。この清掃装置は窓ガラスのガラスの清掃と網戸の網の清掃に兼用されるものであって、第一清掃部材１と第二清掃部材２を一組として構成されている。第一清掃部材１はガラスや網の一方（屋内側）の表面に沿って移動するように操作されるものであって、ガラスや網と対向する正面には洗浄部（図示省略）が設けられていると共にガラスや網の反対側に向く背面には取手部４が形成されている。また、第二清掃部材２はガラスや網を介して（挟んで）第一清掃部材１と磁着され、移動する第一清掃部材１に追随してガラスや網の他方（屋外側）の表面に沿って移動するものであり、ガラスや網と対向する正面には第一清掃部材１と同様の洗浄部３が設けられている。また、第一清掃部材１の正面と第二清掃部材２の正面には、移動させやすいように、ガラスや網の表面で転動するローラー７が設けられている。
【０００３】
上記の洗浄部３は給水体２２とワイパー２１で構成されている。給水体２２はフェルト等で形成されるものであって、水あるいは洗剤を含む水などの洗浄液を保水する保水機能とこの保水した洗浄液をガラスや網の表面に供給する給水機能を有するものである。また、ワイパー２１はゴム等の弾性体で形成されるものであって、給水体２２から洗浄液が供給されたガラスや網の表面に先端が弾接して摺動することによって、洗浄液及びこれにより浮き上がった汚れを掻き取って集める集水機能を有するものである。
【０００４】
このような清掃装置でガラスや網を清掃するにあたっては、まず、ガラスや網を挟んで第一清掃部材１と第二清掃部材２を対向させて配置し、ガラスや網を介して第一清掃部材１と第二清掃部材２を磁着させる。この時、第一清掃部材１の洗浄部はガラスや網の一方の表面に当接し、第二清掃部材２の洗浄部３はガラスや網の他方の表面に当接する。次に、取手部４を握って第一清掃部材１をガラスや網の一方の表面に沿って略水平に移動させる。この時、第二清掃部材２は第一清掃部材１に追随してガラスや網の他方の表面に沿って移動する。そして、第一清掃部材１が移動することにより、第一清掃部材１の洗浄部がガラスや網の一方の表面で摺動し、この洗浄部の摺動によりガラスや網の一方の表面が清掃され、また、第二清掃部材２が移動することにより、第二清掃部材２の洗浄部３がガラスや網の他方の表面で摺動し、この洗浄部３の摺動によりガラスや網の他方の表面が清掃されるのである。
【０００５】
ところで上記の清掃装置では、ローラー７を軸部に回転自在に取り付けると共に第一清掃部材１や第二清掃部材２にその内部にまで貫通する軸受け孔を設け、軸部を軸受け孔に差し込んで固定することによって、ローラー７を第一清掃部材１や第二清掃部材２に取り付けるようにしている。
【０００６】
【発明が解決しようとする課題】
しかし、上記のように第一清掃部材１や第二清掃部材２に軸受け孔を形成すると、給水体２２に洗浄液を保水させるために洗浄液に第一清掃部材１や第二清掃部材２を浸漬させたときに、軸受け孔から第一清掃部材１や第二清掃部材２の内部に洗浄液が侵入することとなり、従って、第一清掃部材１や第二清掃部材２に内蔵される磁石や磁性体を防水しなければならず、第一清掃部材１や第二清掃部材２とは別体に形成される防水用の部品が必要となってコストが高くなるという問題があり、また、防水用の部品を取り付ける作業が必要となって製造工程が増加するという問題があった。しかも、軸部を固定した後に軸部を簡単に取り外すことができず、軸部あるいはローラー７のみの補修や交換を行うことが難しいという問題があった。
【０００７】
本発明は上記の点に鑑みてなされたものであり、コストや製造工程を低減することができ、しかも軸部やローラーの補修や交換を容易に行うことができる清掃装置を提供することを目的とするものである。
【０００８】

【００１６】
【発明の実施の形態】
以下、本発明の実施の形態を説明する。
【００１７】
本発明の清掃装置は、第一清掃部材１と第二清掃部材２とで形成されている。
【００１８】
図３（ａ）（ｂ）（ｃ）及び図４（ａ）（ｂ）（ｃ）で示すように、第一清掃部材１は、正面側（ガラスや網と対向する側）が開口する略箱状の筺体部１０と、筺体部１０の正面の開口に装着される第一清掃プレート１１とで構成されている。筺体部１０は第一清掃プレート１１側の正面が開口する略箱状に形成された取手部４と、取手部４の左右の開口縁部及び上側の開口縁部に取手部４を囲うように延設される延設部１２と、延設部１２の上端に第一清掃プレート１１の方に向かって延設される上係止片１３と、取手部４の下側の開口縁部及び延設部１２の下端に第一清掃プレート１１の方に向かって延設される下係止片１４とを具備して形成されている。延設部１２の取手部４よりも上側の部分は背方に向かって凸曲する凸曲面６１として形成されている。また、取手部４の上面は取手部４を握った手の人差し指を折り曲げて当接させる指当接面５として形成されている。
【００１９】
延設部１２の左右の側部は上下方向に長いワイパー取付片１５として形成されており、ワイパー取付片１５の先端には第一清掃プレート１１の正面（外面）側に延設されるワイパー係止片１６が全長に亘って形成されている。また、取手部４の側面には上下方向に長い滑り止め突起１７が設けられている。さらに、筺体部１０の内部には棒状（筒状）のリブ１８ａ、１８ｂ、１８ｃが設けられている。最も上側のリブ１８ａは凸曲面６１の内側に、残りのリブ１８ｂ、１８ｃは取手部４の内側に設けられており、真ん中のリブ１８ｂの先端は係合部１９として形成されている。
【００２０】
第一清掃プレート１１は、第一プレート本体２０、洗浄部３を構成するワイパー２１と給水体２２、及びローラー７を具備して形成されている。第一プレート本体２０は筺体部１０側の背面が開口する略箱状に形成される磁着部２３と、磁着部２３の左右の開口縁部の全長に亘って延設される給水体取付片２４と、磁着部２３の上側の開口縁部及び給水体取付片２４の上端部に筺体部１０の方に向かって延設される上係止部３０と、磁着部２３の下側の開口縁部及び給水体取付片２４の下端部に筺体部１０の方に向かって延設される下係止部３５と、磁着部２３の略中央部に筺体部１０の方に向かって突設される係着部３１とを具備して形成されている。また、給水体取付片２４の側端にはワイパー係止片３４が突設されている。そして、磁着部２３の背面側（内面側）には磁石３２が係着部３１を挟んで上下に一つずつ設けられていると共に両方の磁石３２の背面に接触するようにして磁着部２３にヨーク３３が収納されている。この時、係着部３１はヨーク３３を貫通してヨーク３３の背面側に突出している。
【００２１】
また、第一プレート本体２０の磁着部２３の正面は清掃時にガラス又は網の表面と対向する面であって、磁着部２３には複数個のローラー収納凹部２５が凹設されており、各ローラー収納凹部２５にローラー７が収納されている。尚、図３（ｃ）に示すように、この実施の形態では左右一対のローラー７を一組とし、この組を上下に３個設けて形成されている。ローラー７は上下に長い略円棒状に形成されるものであって、その上下の略中央部には接触部２６がローラー７の外周の全長に亘って突設されている。また、ローラー７には上下に貫通する軸部２７が設けられており、軸部２７に対してローラー７が回転自在に取り付けられている。そして、軸部２７の上端と下端がローラー収納凹部２５内において磁着部２３に固定されることで、ローラー７が第一プレート本体２０に回転自在に取り付けられている。この時、ローラー７はローラー収納凹部２５にほぼ収納されているが、接触部２６はローラー収納凹部２５から正面側に突出している。このローラー７は第一清掃部材１が移動する際にガラスや網の表面で転動するものであって、このことで第一清掃部材１が移動しやすくなるのである。また、ローラー７は後述の第二清掃部材２にも設けられており、第二清掃部材２が移動する際にガラスや網の表面で転動するものであって、このことで第二清掃部材２が移動しやすくなるのである。
【００２２】
給水体２２はフェルト等で形成されるものであって、水あるいは洗剤を含む水などの洗浄液を保水する保水機能とこの保水した洗浄液をガラスや網の表面に供給する給水機能を有するものである。この給水体２２は上下に長い矩形状に形成されており、第一プレート本体２０の給水体取付片２４の正面側に全長に亘って取り付けられている。ワイパー２１はゴム等の弾性体で形成されるものであって、洗浄液が供給されたガラスや網の表面に先端が弾接して摺動することによって、洗浄液及びこれにより浮き上がった汚れを掻き取って集める集水機能を有するものである。
【００２３】
そして、第一清掃部材１は筺体部１０の正面の開口に第一清掃プレート１１を装着することによって形成される。この時、筺体部１０の上係止片１３と下係止片１４と係合部１９を、第一清掃プレート１１の上係止部３０と下係止部３５と係着部３１にそれぞれ係合させる。また、リブ１８ａ、１８ｃの先端をヨーク３３の背面側に当接させ、リブ１８ａ、１８ｃと第一プレート本体２０の間で磁石３２とヨーク３３を挟持して保持することによって、第一清掃部材１に磁石３２とヨーク３３を内蔵させる。さらに、ワイパー２１をワイパー取付片１４の正面側に配置し、ワイパー係止片１６、３４とワイパー取付片１４の間でワイパー２１の基部を挟持して保持することによって、第一清掃部材１にワイパー２１を取り付けるようにする。
【００２４】
図５（ａ）（ｂ）及び図６（ａ）（ｂ）（ｃ）で示すように、第二清掃部材２はカバー４０と、カバー４０の正面側に装着される第二清掃プレート４１とで構成されている。カバー４０は略平板状に形成されており、その上端には第二清掃プレート４１の正面側に延設される上係合片４２が形成されていると共にカバー４０の下端には第二清掃プレート４１の正面側に延設される下係合片４３が形成されている。また、カバー４０の側部はワイパー取付片５５として形成されており、ワイパー取付片５５の端部には第二清掃プレート４１の正面側に延設されるワイパー係止片４４が突設されている。さらに、カバー４０の略中央部には正面側に突出する結合部４５が形成されている。
【００２５】
第二清掃プレート４１は第一清掃プレート１１の厚みを薄く形成した点及びローラー７の個数が少ない点を除いては、第一清掃プレート１１とほぼ同等に形成されている。すなわち、第二清掃プレート４１は、第二プレート本体４６、洗浄部３を構成するワイパー２１と給水体２２、及びローラー７を具備して形成されている。第二プレート本体４６は背面が開口する略箱状に形成される磁着部４７と、磁着部４７の左右の開口縁部の全長に亘って延設される給水体取付片４８と、磁着部４７の上側の開口縁部及び給水体取付片４８の上端部にカバー４０の方に向かって延設される上係合部４９と、磁着部４７の下側の開口縁部及び給水体取付片４８の下端部にカバー４０の方に向かって延設される下係合部５０と、磁着部４７の略中央部にカバー４０の方に向かって突設される取着部５１とを具備して形成されている。また、給水体取付片４８の側部にはワイパー係止片５２が突設されている。そして、磁着部４７の背面側（内面側）には磁石３２が取着部５１を挟んで上下に一つずつ設けられていると共に両方の磁石３２の背面側に接触するようにして磁着部４７にヨーク３３が収納されている。この時、取着部５１はヨーク３３を貫通してヨーク３３の背面側に突出している。
【００２６】
また、第二プレート本体４６の磁着部４７は清掃時にガラス又は網の表面と対向する面であって、磁着部４７には複数個のローラー収納凹部２５が凹設されており、各ローラー収納凹部２５にローラー７が収納されている。尚、図５（ａ）に示すように、この実施の形態では左右一対のローラー７を一組とし、この組を上下に２個設けて形成されている。ローラー７及びその取り付けは第一清掃プレート１１のものと同様である。また、給水体２２及びその取り付けは第一清掃プレート１１のものと同様である。さらに、ワイパー２１は第一清掃プレート１１のものと同様のものである。
【００２７】
そして、第二清掃部材２はカバー４０の正面に第二清掃プレート４１を装着することによって形成される。この時、カバー４０の上係合片４２と下係合片４３と結合部４５を、第二清掃プレート４６の上係合部４９と下係合部５０と取着部５１にそれぞれ係合させる。また、カバー４０の正面をヨーク３３の背面側に当接させ、カバー４０と第二プレート本体４６の間で磁石３２とヨーク３３を挟持して保持することによって、第二清掃部材２に磁石３２とヨーク３３を内蔵させる。さらに、ワイパー２１をワイパー取付片５５の正面側に配置し、ワイパー係止片４４、５２とワイパー取付片５５の間でワイパー２１の基部を挟持して保持することによって、第二清掃部材２にワイパー２１を取り付ける。
【００２８】
尚、第一清掃部材１と第二清掃部材２の両方に磁石を設ける必要はなく、第一清掃部材１と第二清掃部材２の一方に磁石を設けると共に第一清掃部材１と第二清掃部材２の他方に磁性体を設けるようにしてもよい。
【００２９】
上記のように形成される清掃装置を用いて窓ガラスのガラスの表面や網戸の網の表面を清掃するにあたっては、次のようにして行う。まず、第一清掃部材１と第二清掃部材２を洗浄液に浸漬するなどして給水体２２に洗浄液を含浸させて保水させる。次に、ガラスや網を挟んで第一清掃部材１と第二清掃部材２を対向させて配置し、ガラスや網を介して第一清掃部材１と第二清掃部材２を磁石３２及びヨーク３３によって磁着させる。この時、第一清掃部材１のワイパー２１と給水体２２とローラー７の接触部２６がガラスや網の一方（屋内側）の表面に当接し、第二清掃部材２のワイパー２１と給水体２２とローラー７の接触部２６がガラスや網の他方（屋外側）の表面に当接する。次に、取手部４を握って第一清掃部材１を操作してガラスや網の一方の表面に沿って移動させる。移動させる方向はワイパー２１と給水体２２が並ぶ方向で横方向（略水平方向）である。そして、この第一清掃部材１の移動により、給水体２２がガラスや網の一方の表面で摺動して洗浄液が供給されると共に洗浄液が供給されたガラスや網の一方の表面でワイパー２１が摺動することになり、給水体２２から供給された洗浄液により浮き上がった汚れがワイパー２１で掻き取られて集められて、ガラスや網の一方の表面が第一清掃部材１で清掃されるのである。
【００３０】
また、第二清掃部材２は第一清掃部材１に磁着されているので、第一清掃部材１に追随してガラスや網の他方の表面に沿って移動することになり、この第二清掃部材２の移動により、給水体２２がガラスや網の他方の表面で摺動して洗浄液が供給されると共に洗浄液が供給されたガラスや網の他方の表面でワイパー２１が摺動することになり、給水体２２から供給された洗浄液により浮き上がった汚れがワイパー２１で掻き取られて集められて、ガラスや網の他方の表面が第二清掃部材２で清掃されるのである。
【００３１】
このようにして本発明では、給水体２２とワイパー２１からなる洗浄部３を具備するので、ガラスや網の表面に洗浄液を供給する作業とガラスや網の表面から汚れを掻き取る作業とを第一清掃部材１と第二清掃部材２を移動させるだけで行うことができ、清掃を効率よく行うことができるものである。
【００３２】
図７に第一プレート本体２０を示す。上述のように、第一プレート本体２０の磁着部２３のガラスや網に対向する正面にはローラー収納凹部２５が設けられている。図１（ａ）に示すように、ローラー収納凹部２５は磁着部２３の正面と側面に開口しており、ローラー収納凹部２５の上下の内面は軸部２７の軸方向（上下方向）と直交する軸受け部６０として形成されている。この軸受け部６０はローラー収納凹部２５の底面から突出する凸状段部に形成されている。また、軸受け部６０にはローラー収納凹部２５と磁着部２３の給水体取付片２４側の側面（外側面）に開口する軸取付溝６５が凹設されている。つまり、ローラー収納凹部２５の上側の内面を形成する上側の軸受け部６０には下面と側面に開口する軸取付溝６５が、ローラー収納凹部２５の下側の内面を形成する下側の軸受け部６０には上面と側面に開口する軸取付溝６５がそれぞれ形成されている。
【００３３】
上記のように形成される軸取付溝６５の側面の開口は軸着脱開口６１として形成されていると共に軸取付溝６５の軸着脱開口６１と反対側の端部は軸部２７を保持して設置するための設置部６６として形成されており、さらに、軸着脱開口６１と設置部６６の間は軸入出路６９として形成されている。また、軸受け部６０において軸取付溝６５よりも正面側に位置する部分は弾性変形が可能な薄片の抜け止め片６３として形成されている。さらに、軸取付溝６５の内面の抜け止め片６３と対向する位置には軸抜け止め部６４が軸入出路６９に突出して設けられている。そして、これら抜け止め片６３と軸抜け止め部６４とで抜け止め手段６２が形成されている。
【００３４】
軸抜け止め部６４は軸入出路６９に面する誘い込み部６７と設置部６６に面する軸当接面６８とを有して形成されている。誘い込み部６７は軸着脱開口６１から設置部６６に向かうにしたがって抜け止め片６３（正面側）に徐々に近づくように傾斜する傾斜面（テーパー面）又は曲面として形成されている。軸当接面６８は誘い込み部６７の軸着脱開口６１と反対側の端部に連続して形成されており、設置部６６の奥側に向かうにしたがって抜け止め片６３から徐々に遠ざかるように傾斜する傾斜面又は曲面として形成されている。軸当接面６８は設置部６６に保持される軸部２７の外周面に当接する部分であり、軸部２７との摩擦を小さくするために軸部２７の外周面に沿う凹曲面に形成するのが好ましい。
【００３５】
そして、第一プレート本体２０にローラー７を取り付けるにあたっては、次のようにして行う。まず、ローラー７を上下に貫通してローラー７から突出する軸部２７の端部を軸着脱開口６１から軸取付溝６５の軸入出路６９に挿入し、設置部６６の方に向かって軸部２７を押圧する。このように押圧されると軸部２７は、誘い込み部６７の傾斜面で誘導されながら、図１（ｂ）に矢印で示すように、設置部６６に向かって軸入出路６９に挿入されていくが、この時、軸部２７は誘い込み部６７により抜け止め片６３側に押圧されると共に軸部２７により抜け止め片６３が押圧されて正面側（軸取付溝６５から離れる方向）に弾性変形することになる。つまり、図１（ｂ）に示すように、抜け止め片６３を弾性変形させながら軸部２７を軸入出路６９に挿入していくようにする。
【００３６】
この後、さらに軸部２７を挿入していくと軸部２７が軸取付溝６５の設置部６６に到達する。このように軸部２７が設置部６６に到達すると、誘い込み部６７による軸部２７の押圧が解除されると共に軸部２７による抜け止め片６３の押圧が解除されて抜け止め片６３が弾性変形前の元の状態に戻り、抜け止め片６３が軸部２７の外周面に弾性的に当接することになり、また、軸抜け止め部６４の軸当接面６８が軸部２７の外周面に当接することになる。このようにして抜け止め片６３と軸当接面６８と軸取付溝６５の内面とで軸部２７を挟持することによって、ローラー収納凹部２５にローラー７を収納した状態で軸部２７を軸受け部６０の軸取付溝６５に固定して取り付けることができる。尚、図においてローラー７の一部を点線で示す場合がある。
【００３７】
また、軸取付溝６５から軸部２７を取り外すにあたっては、設置部６６から軸着脱開口６１の方に向かう力を軸部２７に加え、抜け止め片６３を正面側に弾性変形させながら軸部２７を設置部６６から軸入出路６９に移動させる。この後、軸部２７を軸着脱開口６１の方に向かって移動させて軸部２７を軸着脱開口６１から抜き出すことによって、軸取付溝６５から軸部２７を取り外すことができ、同時に、軸部２７に取り付けられたローラー７もローラー収納凹部２５から取り外すことができる。
【００３８】
尚、ここでは第一プレート本体２０について説明したが、第二プレート本体４６も厚みが薄く形成されている以外は、第一プレート本体２０と同様に形成されており、ローラー７や軸部２７の取り付け取り外しも同様にして行われる。
【００３９】
このように本発明では、ローラー収納凹部２５の内面である軸受け部６０の表面に軸取付溝６５を形成し、軸取付溝６５にローラー７の軸部２７を取り付けると共に軸部２７が軸取付溝６５から抜けないように抜け止め手段２６で保持したので、第一清掃部材１と第二清掃部材２に軸部２７を差し込むための孔を設ける必要が無くなって、第一清掃部材１と第二清掃部材２をその内部に洗浄液が侵入しない完全防水に形成することが可能となるものである。従って、第一清掃部材１と第二清掃部材２に内蔵される磁石３２や磁性体、あるいはヨーク３３を防水するための部品が不要となり、また、防水用の部品を取り付ける作業も不要となって、コスト及び製造工程の低減を図ることができるものである。
【００４０】
しかも、抜け止め手段６２の抜け止め片６３を弾性変形させながら軸部２７を軸取付溝６５に着脱自在に形成したので、第一清掃部材１において筺体部１０と第一清掃プレート１１を組み立てた後、あるいは第二清掃部材２においてカバー４０と第一清掃プレート４１を組み立てた後に、軸部２７及びローラー７の取り付けと取り外しを行うことができ、軸部２７及びローラー７の故障及び破損の際に軸部２７やローラー７のみの補修や交換を容易に行うことができるものである。
【００４１】
また、軸部２７の正面側（清掃時にガラス側あるいは網側となる方）に抜け止め手段６２の抜け止め片６３を設けたので、第一清掃部材１あるいは第二清掃部材２のガラスや網に対向する面に対する垂直方向に生じる力が軸部２７に加わっても、軸部２７を抜け止め片６３で押圧して軸取付溝６５の設置部６６から抜けないようにすることができる。
【００４２】
また、軸部２７を挟んで抜け止め片６３と対向させて軸抜け止め部６４を第一清掃部材１と第二清掃部材２のガラスや網と対向する面に形成したので、図２（ａ）に示すように、清掃時にローラー７がガラス７０や網の表面に接触して加圧されることによって、軸部２７がガラス７０や網の表面から離れる方向に移動しても、軸部２７が軸着脱開口６１の方向に移動するのを軸抜け止め部６４で係止して防ぐことができ、清掃時に第一清掃部材１と第二清掃部材２を横方向（水平方向）に移動させても、ローラー７及び軸部２７が脱落しないようにすることができるものである。
【００４３】
また、ローラー７を収納するためのローラー収納凹部２５を形成し、ローラー収納凹部２５の内壁面を軸受け部６０として形成したので、軸受け部６０に軸部２７を取り付けるのと同時にローラー収納部２５へローラー７を収納して取り付けることができ、軸部２７及びローラー７の取り付けが容易に行うことができて製造作業の低減を図ることができるものであり、しかも、ローラー７がローラー収納凹部２５に収納されて突出せず、第一清掃部材１と第二清掃部材２の薄型化を図ることができるものである。
【００４４】
また、軸着脱開口６１から軸取付溝６５に挿入された軸部２７を設置部６６に誘導するための誘い込み部６７を軸抜け止め部６４に設けたので、軸部２７の挿入時に誘い込み部６７で軸部２７をガイドすることによって、軸部２７が抜け止め片６３や軸抜け止め部６４に引っ掛かったり、軸部２７の無理な押圧で抜け止め片６３が破損されたりすることを防止でき、軸部２７及びローラー７の取り付けが容易に行うことができて製造作業の低減を図ることができるものである。
【００４５】
