Description

【０００１】
【発明の属する技術分野】
本発明は緊急事態用浴室ドアに関する。ここで緊急事態とは、例えば浴室内で人が倒れた場合を言う。このような場合本発明の緊急事態用浴室ドアは、ドア本体から救助用中扉を開放することができる。
【０００２】
【従来の技術】
従来の一例としては、特開平６−３０７１６９号公報に記載の緊急脱出扉付き浴室ドアがある。この公報記載の浴室ドアは、レバーハンドルを有するドア本体と、このドア本体に一体的に組込まれた緊急脱出ドアとから成り、前記緊急脱出ドアは、まず緊急時に非常用解錠装置の操作部材を操作し、ドア本体と緊急脱出ドアとの係合を常に保持している係合手段を解除する。ドア本体と緊急脱出ドアを一体的に結合している係合手段は、ドア本体の縦框に沿って固定的に設けられた端面ハット型の被係合部材と、この被係合部材の凹所にバネ部材のバネ力により常時圧接係合するように付勢され、かつ、緊急脱出ドアの縦縁部に取付けられた突起状係合部材とから成る。
【０００３】
そこで、凹所側の被係合部材と凸側の係合部材との係合は、ドア本体側に備えられた非常用解錠装置の操作部材によって係合解除される訳であるが、この係合解除は、ドア本体の外壁面から突出する操作つまみを有する長板片状操作部材を縦方向へと移動操作すると、その解除レバーの先端部が緊急脱出ドアの係合部材をバネ部材のバネ力に抗して係合解除の方向（見付け方向）へと押圧する。
【０００４】
次に係合手段の係合を解除したならば、緊急脱出ドアを浴室ドアの幅方向へとスライド移動させ、さらに、緊急脱出ドアを縦軸を介してドア本体から脱衣室側へと回転開放させる。したがって、次に列挙するような問題点があった。
▲１▼縦框に対する緊急脱出ドアの「がたつき」を防止することができる利点を有するが、係合手段はその構成する部品点数が多く、また非常用解錠装置の解除レバーとの当接関係も考慮しなければならない。
▲２▼非常用解錠装置を構成する部品点数も多い。例えば縦框に対してドアの奥行き方向に合わせられるサッシ状支持部材、この支持部材の窓孔から水平軸を介して先端部が突出する解除部材、この解除部材の内端部を軸支する長板片状操作部材、この操作部材の適宜箇所に設けられた操作用摘み等が必要である。そして、これらの各部材をドア本体の縦枠に取付けなければ成らない。したがって、ドア本体及び緊急脱出ドアの奥行き（見込み幅）の縁部が拡大化する。
▲３▼緊急脱出ドアをそのまま開放すると、ドア本体のレバーハンドルが邪魔になる。そこで、レバーハンドルとの衝突を回避するために緊急脱出ドアをスライド型に構成している。そのため緊急脱出ドアに複雑なスライド機構を設けている。
【０００５】
【発明が解決しようとする課題】
本発明は以上のような従来の欠点に鑑み、第１の目的は、緊急時に係合手段の係合状態を解除させた救助用中扉を、そのままの位置から脱衣室側に水平回転させて開放することができることである。この場合ドア本体のレバー状操作部材が邪魔にならないことである。第２の目的は、平常時に操作部材を中扉側にプッシュするとラッチが操作部材の連動してフロント面に収没し、一方、緊急事態発生時に操作部材の回転量規制用ストッパー片を手動で操作（スライド）した後に操作部材を脱衣室側にプル（引き寄せ）すると、ラッチが操作部材に連動しないで、操作部材のみが水平回転することである。第３の目的は、レバー状操作部材を簡単にドア本体の取付け受け座に組込むことができると共に、操作部材をいずれの方向（中扉側と脱衣室側）にそれぞれ水平回転（プッシュとプル）させてもバネ部材のバネ力により浴室ドアの外壁面に対向する位置へと復帰することである。第４の目的は、平常時には操作部材が脱衣室側に回転せず、一方、緊急時には直ちに操作部材の前記回転規制の解消を図ることができることである。
【０００６】
【課題を解決するための手段】
本発明の緊急事態用浴室ドアは、ラッチ９をフロント面に収没させるレバー状の操作部材１０を有するドア本体３と、このドア本体の開口部５に一体的に組込まれた救助用中扉４とから成り、前記救助用中扉４は、平常時にはドア本体並びに救助用中扉４にそれぞれ設けられた係合手段６を介して一体的に係合し、一方緊急時には、係合手段６の係合状態を解除し、また操作部材１０をバネ部材１３のバネ力に抗して脱衣室側へと水平回転させたうえで開放し、前記バネ部材１３は、ドア本体３の取付け受け座１１に突出形成された角型嵌合口部１７に嵌合する操作部材１０の回転部２２内にラッチ９用の駆動片３０と共に組込まれ、さらに、平常時に於いて、操作部材１０が脱衣室側に回転しないように前記嵌合口部１７に操作部材１０の突起板２１と当接するストッパー片５０が摺動可能に設けられていることを特徴とする。
【０００７】
【発明の実施の形態】
図１乃至図１２に示す第１実施例の緊急事態用浴室ドアＸについて説明する。まず、図１を参照に浴室ドアＸの実施形態を簡単に説明する。符号Ａは浴室、Ｂは脱衣室、１はドア用枠、Ｘは枢軸２を介して前記ドア用枠１に開放自在に取付けられた緊急事態（救出）用浴室ドアである。
【０００８】
普通一般に浴室ドアは、浴室Ａ側に開放する。したがって、浴室Ａ内で人が倒れた緊急事態発生の場合には、図１の仮想線で示すように、浴室ドアＸを浴室Ａ側に開いて人を助け出さなければならない。本発明の浴室ドアＸも、もちろん浴室Ａ側に開放するので、普通一般の浴室ドアと同様に浴室ドアＸを浴室Ａ側に開き、倒れた人を助け出すことができる。
【０００９】
次に本発明の浴室ドアＸの構成について詳しく説明する。この浴室ドアＸは、基本的には、ドア本体３と、このドア本体に一体的に組み込まれた救助用中扉４と、平常時この救助用中扉が前記ドア本体から外れないように一体化させる係合手段６と、ラッチ９をドア本体のフロント面から収没させる操作部材１０と、この操作部材を常態の位置へ復帰させるバネ部材１３と、平常時に於いて、操作部材１０が脱衣室側に回転しないように取付け受け座１１の嵌合口部１７の係合部２０に摺動自在に設けられた上下の係合爪片５２、５２を有するストッパー片５０とから成る。
【００１０】
そこで、これらの基本的構成部材について順番に説明する。まずドア本体３について説明する。ドア本体３はアルミニュームで、いわゆる矩形枠（サッシ）状に形成されている。図１を基準にすると、３ａは上框、３ｂは下框、３ｃはラッチ側の縦框、３ｄは枢軸２或いは蝶番側の縦框である。矩形枠状のドア本体３は、水が脱衣室Ｂ側に飛散しないように下枠１ａや縦枠１ｂで規制されている。
【００１１】
したがって、ドア本体３は浴室Ａ側に開放可能であるが、脱衣室Ｂ側には開放することができない。そこで、ドア本体３を普通一般の浴室ドアと同様に浴室Ａ側に開放しようとする場合に於いて、人が倒れた状況如何（例えば浴室ドアに当たっている。）によってはドア本体３の開放が非常に困難、或いはドア本体３の開放が人体に対する危険性を含み、次に説明する救助用中扉４を脱衣室Ｂ側に開放する必要性が生じる。
【００１２】
救助用中扉４は、ドア本体３と同一垂直面になるように開口部５内に一体的に組込まれている。この救助用中扉４は、浴室Ａ内で倒れた人（例えば老人）を容易に救出することができるように、やや大きめに形成されている。この中扉４は、そのままドア本体３から完全に分離することができるように矩形枠状ドア本体３に組込んでも良いが、本実施例では図１の仮想線で示すように外方向（脱衣室Ｂ側）に回転開放する。したがって、中扉４は、ドア本体３に枢着する組立て前は、ドア本体３に対して独立した物品である。４ａは中扉４の側端部付近の外壁面に組込んだ把手である。
【００１３】
次に平常時中扉４がドア本体３から外れないように一体化させる係合手段６について説明する。この係合手段６は、図１で示すように浴室ドアＸの上下に一組設けられている。すなわち、７はドア本体３に一端部が軸支されたバー状の係止片、一方、８は中扉４の外壁面に突出状態に固定された鉤状の係合受け片である。本実施例のように係合手段６が浴室ドアＸの外壁面から突出する場合には、図示しないカバーを設けるのが望ましい。この点外観上の理由から係合手段６の突出を極力避けたい場合には、例えば操作摘み部がドア本体３の外壁面から突出するバー状係止片７をドア本体３の縦框３ｃ内に回転自在に組込み、一方、中扉４の側端部にバー状係止片７の自由端部が係合する係合凹所を形成すれば良い。或いはまた係止片７を水平方向に移動する出没自在なスライド部材に構成し、該スライド部材のテーパー状突出先端部が常時中扉４側の係合凹所に係合するように図示しない付勢バネを縦框３ｃに内設しても良い。要は平常時に於いて、中扉４がドア本体３から簡単に開放しなければ良い。
【００１４】
次に図２乃至図５を参照にレバー状の操作部材１０について説明する。この操作部材１０は、ドア本体３の縦框３ｃの中央部に固定された取付け受け座１１に垂直軸１２を介して水平方向に回転可能に軸支され、かつ、取付け受け座１１と操作部材１０との組合わせ部分に内装されたバネ部材１３により、長板状操作部１０ａが常に浴室ドアＸの外壁面に対向する位置へと復帰する。
【００１５】
本発明の操作部材１０は、長板状操作部１０ａを中扉４の外壁面側に押圧すると、ラッチ９がフロント面より収没し、一方、長板状操作部１０ａから手を離すと、操作部材１０は前記バネ部材１３のバネ力により復帰すると共に、ラッチ９がラッチバネ４１のバネ力によりフロント面から突出する。この点ラッチ９は、普通一般のレバーハンドルと同様に操作部材１０の作動に連動する。
【００１６】
また操作部材１０は、緊急時に、まず取付け受け座１１の嵌合口部１７の係合部２０に係合するストッパー片５０を取付け受け座１１側へと水平方向にスライドさせ、次にドア本体３と中扉４との係止手段６の係合を解き、前記中扉４を脱衣室Ｂ側に開放すると、その障害にならないように脱衣室Ｂ側に水平回転する。この時ドア本体３のラッチ９は、操作部材１０の水平回転に連動（収没）しない。そして、長板状操作部１０ａから手を離すと、操作部材１０は前記バネ部材１３のバネ力により元の位置へと復帰する。
【００１７】
そこで、本発明の操作部材１０に関連する部材並びに操作部材１０についてさらに説明する。まず取付け受け座１１の構成である。取付け受け座１１は、図４で示すように長座型のものが用いられている。すなわち、１５は縦長状の取付け基板部で、この取付け基板部１５の上下には、一対の固着具用小孔１６が形成されている。１７は取付け基板部１５の中央部に連設形成された角型の嵌合（口）部で、この嵌合口部１７には、垂直軸１２用の一対の軸孔１８が形成されている。
【００１８】
しかして、取付け受け座１１は、嵌合口部１７から取付け基板部１５に至って貫通状態の角筒状に形成され、図６で示すように前記取付け基板部１５の１つの内壁部１５ａはやや肉厚状に形成されている。そして、内壁部１５ａの内壁面は、嵌合口部１７の奥側からラッチ９側の内側開口に至るまで弧状であり、該内側開口を多少塞いでいる。
【００１９】
また前記嵌合口部１７の上・下壁１７ａ、１７ｂの取付け受け座１１の取付け基板部１５寄りの端部には、凹所状の対向溝１９、１９がそれぞれ形成され、これらの対向溝１９、１９は前記取付け基板部１５に直交している。そして、上下の対向溝１９、１９の内壁底面には、図８で示すように取付け基板部１５に対して平行の突起状係合部２０、２０がそれぞれ所要間隔を有して複数個設けられている。
【００２０】
次に操作部材１０の特徴は、例えば図５に良く示されている。そこで、図５を基準にすると、１０ａは前述したように長板状操作部で、この操作部１０ａの内壁面の一端（右）部には、上下に所要間隔を有して水平方向の突起板２１が一対設けられている。これら上下の突起板２１は、平常時に於いて、操作部材１０が脱衣室側に回転しないように前記嵌合口部１７に摺動自在に設けられたストッパー片５０に当接する機能及び外観上化粧板としての美的機能を発揮する。
【００２１】
したがって、上下の突起板２１は、本実施例では操作部１０ａの内壁面からそれぞれ水平状態に突出する化粧板部２１ａ、２１ａと、これらの化粧板部２１ａ、２１ａの端部寄りの部位から取付け受け座１１の取付け基板部１５の方向へと延びる突起部２１ｂとを有する。
【００２２】
２２は上下の突起板２１、２１内に位置するように操作部１０ａの内壁面に突設され、かつ、取付け受け座１１の少なくとも嵌合口部１７に嵌め込まれる（嵌合する）ケース状回転部である。この回転部２２は、形状的には、操作部１０ａの内壁面の一端部から人間の手首状に延びる連設支持部２３と、この連設支持部部２３にさらに拳状に連設し、かつ、ラッチ９を連動させるためのアーム状駆動片３０の基端部３０ａ及び操作部材１０を復帰させるためのバネ部材１３を略収納する一部開口２４のケース状部２５とから成る。
【００２３】
しかして、前記ケース状部２５の垂直壁部２５ａに交差方向に対向連設する上下の段差状水平板部２５ｂ、２５ｂの中央部には、垂直軸１２用の枢支孔３２、３２が形成されている。また上下の水平板部２５ｂ、２５ｂの内壁面の適宜箇所には、バネ部材１３の形状を考慮し、該バネ部材１３の上下のリング状部１３ａ、１３ａが合理的に位置すべき収納空間形成用のアングル状段差部２５ｃ、２５ｃがその内壁面に沿って形成されている。そして、ケース状部２５の適宜部位（例えば垂直壁部２５ａの側端部）には、バネ部材１３の下端部１３ｂを係止する係合切欠部２６が形成されている。
【００２４】
次に操作部材１０を復帰させるバネ部材１３及びラッチ９を出没させる駆動片３０について説明する。バネ部材１３は、図６で示すように駆動片３０の基端部３０ａに形成された垂直軸孔３５に、その上下のリング状部１３ａ、１３ａが合うように該駆動片３０に添設した状態で操作部材１０の回転部２２内に組込まれる。その際、下端部１３ｂは回転部２２の係合切欠部２６に係止され、一方、上端部１３ｃは、取付け受け座１１の内壁面に圧接する。また上下のリング状部１３ａ、１３ａを結ぶコ字型状の中途部１３ｄは、駆動片３０のアーム状駆動部３０ｂの一側（垂直）面に当接する。そして、アーム状駆動部３０ｂの先端部は取付け受け座１１の内側開口から突出し、図１０で示すようにラッチ出没機構Ｙを構成する回転レバー（被駆動片）４０に係合する。
【００２５】
ここで、図１０を参照にラッチ出没機構Ｙを構成する各部材を簡単に説明する。４１はラッチ９をフロント板４２から常時突出するように付勢するラッチバネ、４３はラッチバネ４１の一端部を受けるバネ受け板、４４はバネ受け板４３と回転レバー４０との間に介在するＬ字型の係合回転片で、この係合回転片４４の一端部４４ａはラッチ９の後端部に形成、或いは設けたラッチ係合部４５に係合する。また係合回転片４４の他端部４４ｂは回転レバー４０に係合する。
【００２６】
最後に弾性のストッパー片５０について説明する。ストッパー片５０は、平常時に於いて、操作部材１０が脱衣室Ｂ側に回転しないように規制するストッパー機能を有し、本実施例では取付け受け座１１の嵌合口部１７に水平方向へと摺動可能に設けられている。
【００２７】
しかして、本実施例のストッパー片５０は、図４で示すように上下に係合爪片５２、５２を有する端面リップミゾ形状の弾性係脱部材であり、前述した取付け受け座１１の嵌合口部１７の対向溝１９にそれぞれ設けた上下の係合部２０、２０に対して係脱自在である。なお、前記係合爪片５２、５２の先端部は、対応する係合部２０が水平棒状の突起であるため、弧状に切欠されている。
【００２８】
上記構成に於いて、平常時、浴室ドアＸを浴室Ａ側に開けようとする場合には、図９で示すように操作部材１０の操作部１０ａを中扉４側に押す。この場合操作部材１０は、その突起板２１の化粧板部２１ａの一端部がストッパー片５０の側壁面に当る所まで回転する。つまり、平常時に於いては、図２及び図３で示すように前記突起板２１の化粧板部２１ａの一端部は、ストッパー片５０から離れているので、操作部材１０を中扉４側にプッシュすることができる。
【００２９】
しかして、操作部材１０がバネ部材１３のバネ力に抗して垂直軸１２を支点に内側方向へ水平回転すると、操作部材１０のケース状回転部２２に支持されるように設けられたアーム状駆動片３０の先端部は、図１０で示すように矢印方向に移行する。これにより、ラッチ出没機構Ｙを構成する回転レバー４０及び係合回転片４４は、それぞれ矢印方向（時計／反時計方向）に回転し、その結果、ラッチ９はラッチ案内板４６に案内され、かつ、ラッチバネ４１のバネ力に抗して収没する。したがって、浴室ドアＸをそのまま開放することができる。
【００３０】
一方、緊急時、浴室ドアＸの中扉４をドア本体３から開放する場合には、まず係合手段６の係止片７を係合受け片８から外し、また図８の矢印で示すようにストッパー片５０を手動で取付け受け座１１の取付け基板部１５側へとスライドさせる。この時ストッパー片５０は弾性係脱部材であるため、多少外拡変位を繰り返し、操作部材１０側の係合部２０から取付け基板部１５側の係合部２０へと移行する。その結果、ストッパー片５０が操作部材１０の突起板２１の突起部２１ｂに対して逃げた状態となり、図１１で示すように操作部材１０を外方向（脱衣室Ｂ側）に引き寄せることができる。
【００３１】
そこで、図１２で示すように中扉４の把手４ａに手（例えば右手）を掛け、中扉４を手前側に引く。この時、他方の手（例えば左手）を操作部材１０の操作部１０ａの内側に差し入れ、外方向に引き寄せる。操作部材１０は他方の手で外方向に引き寄せられると、バネ部材１３のバネ力に抗して水平移転し、中扉４から離れる。したがって、このようにドア本体３に対して中扉４を開放する時には、操作部材１０は全く障害にならない。そして、中扉４を所望状態まで開放した後操作部１０ａから手を放すと、操作部材１０はバネ部材１３のバネ力により復帰する。
【００３２】
【実施例】
まず第１実施例に於いて、係合手段６を構成するバー状係止片７と鉤状係合受け片８の取付け位置は逆であっても良い。また操作部材１０を復帰させるバネ部材１３は、１本のバネ線材で構成し、操作部材１０をいずれの方向（中扉側と脱衣室側）にそれぞれ水平回転（プッシュとプル）させても復帰力が働くようにしているが、設計如何によっては２本のバネ線材で構成しても良い。また上下の対向溝１９内に設けた突起状係合部２０は、それぞれ１個づつであっても良い。
【００３３】
次に図１３及び図１４を参照に本発明の第２実施例について説明する。なお、この第２実施例の説明に当たって、前述した第１実施例と同一構成の部分には、同一又は同様の符号を付し、重複する説明を省略する。
【００３４】
まずこの第２実施例は、ストッパー片５０Ａを水平方向へと移動させる際に、該ストッパー片５０Ａが嵌合口部１７Ａに上下動可能に設けた複数個の係合部材２０Ａに対し、スムースに係脱することができることを目的とする。この第２実施例のストッパー片５０Ａは、第１実施例のストッパー片５０のように必ずしも弾性部材である必要はない。
【００３５】
しかして、前記係合部材２０Ａは、各対向溝１９Ａにそれぞれ内装された小バネ６１により常時外（係合）方向に付勢され、この実施例では嵌合口部１７Ａの上・下壁１７ａ、１７ｂにそれぞれ形成された対向溝１９Ａの内壁底面部に係止される係合フランジ部２０ａと、この係合フランジ部２０ａに連設する係合突起部２０ｂとから成る。そして、各係合部材２０Ａの係合突起部２０ｂは、図１３で示すようにストッパー片５０Ａの係合爪片５２にそれぞれ係合する。
【００３６】
上記構成に於いては、ストッパー片５０Ａを水平方向へと移動させると、上下の係合部材２０Ａはそれぞれ小バネ６１のバネ力に抗して嵌合口部１７Ａの内側方向へと後退する。したがって、上述した発明の目的を達成することができる。
【００３７】
【発明の効果】
以上の説明から明らかなように、本発明にあっては次に列挙するような効果がある。
（１）緊急時に係合手段の係合状態を解除させた救助用中扉を、そのままの位置から脱衣室側に水平回転させて開放することができる。
（２）平常時に操作部材を中扉側にプッシュするとラッチが操作部材の連動してフロント面に収没し、一方、緊急事態発生時に操作部材を脱衣室側にプル（引き寄せ）すると、ラッチが操作部材に連動しないで、操作部材のみが水平回転する。したがって、操作部材を通常は普通一般のレバーハンドルとして使用し、一方、緊急時には中扉をスムースに開放する手段として使用することができる。
（３）レバー状操作部材を簡単にドア本体の取付け受け座に組込むことができると共に、操作部材をいずれの方向（中扉側と脱衣室側）にそれぞれ水平回転（プッシュとプル）させてもバネ部材のバネ力により浴室ドアの外壁面に対向する位置へと復帰する。
（４）平常時には操作部材が脱衣室側に回転しないので、使用上の不便さを感じさせない。そして、緊急時にはストッパー片をスライド操作して操作部材の回転規制を容易に解消させることができる。
（５）請求項３に記載の発明は、ストッパー片５０Ａを水平方向へとスムースに移動させることができると共に、移動させた後もストッパー片５０Ａを所定の箇所に確実に停止させることができる。

BACKGROUND OF THE INVENTION
The present invention relates to emergency bathroom doors. Here, an emergency situation refers to a case where a person falls in a bathroom, for example. In such a case, the emergency bathroom door of the present invention can open the rescue middle door from the door body.
[0002]
[Prior art]
As a conventional example, there is a bathroom door with an emergency escape door described in JP-A-6-307169. The bathroom door described in this publication is composed of a door main body having a lever handle and an emergency escape door integrally incorporated in the door main body. The emergency escape door is first an operation member of an emergency unlocking device in an emergency. Is operated to release the engagement means that always maintains the engagement between the door body and the emergency escape door. The engaging means integrally connecting the door main body and the emergency escape door includes an end face hat-type engaged member fixedly provided along the vertical shaft of the door main body, and a concave portion of the engaged member. And a projecting engagement member attached to the vertical edge portion of the emergency escape door.
[0003]
Therefore, the engagement between the engaged member on the recess side and the engaging member on the convex side is released by the operation member of the emergency unlocking device provided on the door body side. To release the engagement, when the long plate-shaped operation member having an operation knob protruding from the outer wall surface of the door body is operated to move in the vertical direction, the tip of the release lever moves the engagement member of the emergency escape door to the spring member. Push in the direction of disengagement (finding direction) against the spring force.
[0004]
Next, when the engagement means is disengaged, the emergency escape door is slid in the width direction of the bathroom door, and the emergency escape door is rotated and released from the door body to the dressing room side via the vertical axis. Let Therefore, there are problems as listed below.
(1) Although it has an advantage that it is possible to prevent the rattling of the emergency escape door against the vertical shaft, the engaging means has a large number of parts, and it is difficult to contact the release lever of the emergency unlocking device. We must also consider close relationships.
(2) The number of parts constituting the emergency unlocking device is also large. For example, a sash-like support member that is aligned with the vertical shaft in the depth direction of the door, a release member that protrudes from the window hole of this support member through a horizontal axis, and a length that supports the inner end of this release member A plate-like operation member, an operation knob provided at an appropriate position of the operation member, and the like are necessary. And each of these members must be attached to the vertical frame of the door body. Therefore, the edge of the depth (expected width) of the door body and the emergency escape door is enlarged.
(3) If the emergency escape door is opened as it is, the lever handle of the door body gets in the way. Therefore, in order to avoid a collision with the lever handle, the emergency escape door is configured as a slide type. Therefore, a complicated slide mechanism is provided on the emergency escape door.
[0005]
[Problems to be solved by the invention]
In view of the above-mentioned conventional drawbacks, the first object of the present invention is to horizontally rotate the rescue middle door, which has been disengaged from the engaging means in an emergency, from the position to the dressing room side. It can be opened. In this case, the lever-like operation member of the door body does not get in the way. The second purpose is that when the operating member is pushed to the middle door side during normal times, the latch is retracted to the front surface in conjunction with the operating member. When the operation member is pulled (pulled) to the dressing room side after being operated (sliding), only the operation member rotates horizontally without the latch being interlocked with the operation member. The third object is that the lever-like operation member can be easily assembled into the mounting seat of the door body, and the operation member can be rotated horizontally (push and pull) in any direction (inside door side and dressing room side). Even if it makes it, it is returning to the position which opposes the outer wall surface of a bathroom door by the spring force of a spring member.

[0007]
DETAILED DESCRIPTION OF THE INVENTION
The emergency bathroom door X of the first embodiment shown in FIGS. 1 to 12 will be described. First, an embodiment of a bathroom door X will be briefly described with reference to FIG. Reference numeral A is a bathroom, B is a dressing room, 1 is a door frame, and X is an emergency (rescue) bathroom door attached to the door frame 1 via a pivot 2 so as to be freely opened.
[0008]
Generally, the bathroom door is generally opened to the bathroom A side. Therefore, in the case of an emergency situation in which a person falls in the bathroom A, the bathroom door X must be opened to the bathroom A side to help the person as shown by the phantom line in FIG. Of course, since the bathroom door X of the present invention is also opened to the bathroom A side, the bathroom door X can be opened to the bathroom A side in the same way as a normal bathroom door, and a fallen person can be helped.
[0009]
Next, the configuration of the bathroom door X of the present invention will be described in detail. The bathroom door X is basically integrated with the door body 3, the rescue middle door 4 integrally incorporated in the door body, and the rescue middle door so that the rescue middle door does not come off from the door body. Engaging member 6, operating member 10 for retracting the latch 9 from the front surface of the door body, spring member 13 for returning the operating member to the normal position, and the operating member 10 being undressed in normal times. It comprises a stopper piece 50 having upper and lower engaging claw pieces 52 and 52 slidably provided on the engaging portion 20 of the fitting port portion 17 of the attachment receiving seat 11 so as not to rotate toward the chamber side.
[0010]
Therefore, these basic components will be described in order. First, the door body 3 will be described. The door body 3 is made of aluminum and is formed in a so-called rectangular frame (sash) shape. With reference to FIG. 1, 3a is an upper rod, 3b is a lower rod, 3c is a vertical rod on the latch side, and 3d is a vertical rod on the pivot 2 or hinge side. The rectangular frame-shaped door body 3 is restricted by the lower frame 1a and the vertical frame 1b so that water does not scatter to the dressing room B side.
[0011]
Therefore, the door body 3 can be opened to the bathroom A side, but cannot be opened to the dressing room B side. Therefore, in the case where the door body 3 is to be opened to the bathroom A side in the same manner as a general bathroom door, the door body 3 is very open depending on the situation in which the person falls down (for example, hits the bathroom door). The opening of the door body 3 involves a danger to the human body, and the need arises to open the rescue middle door 4 described below to the dressing room B side.
[0012]
The rescue middle door 4 is integrated into the opening 5 so as to be in the same vertical plane as the door body 3. The rescue middle door 4 is formed slightly larger so that a person who falls in the bathroom A (for example, an elderly person) can be rescued easily. The middle door 4 may be incorporated into the rectangular frame-shaped door body 3 so that it can be completely separated from the door body 3 as it is. However, in this embodiment, as shown by the phantom line in FIG. Rotate to room B side). Therefore, the middle door 4 is an article independent of the door body 3 before being assembled to the door body 3. Reference numeral 4 a denotes a handle incorporated in the outer wall surface near the side end of the inner door 4.
[0013]
Next, the engaging means 6 for integrating the door 4 so that it does not come off the door body 3 will be described. As shown in FIG. 1, a set of the engaging means 6 is provided above and below the bathroom door X. That is, 7 is a bar-shaped locking piece whose one end is pivotally supported on the door body 3, while 8 is a hook-shaped engagement receiving piece fixed to the outer wall surface of the inner door 4 in a protruding state. When the engaging means 6 protrudes from the outer wall surface of the bathroom door X as in this embodiment, it is desirable to provide a cover (not shown). In order to avoid the protrusion of the engaging means 6 as much as possible for the reason of this point appearance, for example, the bar-shaped locking piece 7 in which the operation knob protrudes from the outer wall surface of the door body 3 is provided in the vertical rod 3c of the door body 3. On the other hand, an engagement recess for engaging the free end portion of the bar-like locking piece 7 may be formed on the side end portion of the inner door 4. Alternatively, the locking piece 7 is configured as a slide member that can move in and out in the horizontal direction, and a tapered protruding tip of the slide member is always engaged with an engagement recess on the side of the middle door 4 (not shown). A force spring may be provided in the vertical rod 3c. In short, it is sufficient that the middle door 4 is not easily opened from the door body 3 in normal times.
[0014]
Next, the lever-like operation member 10 will be described with reference to FIGS. The operation member 10 is pivotally supported by a mounting receiving seat 11 fixed to the center portion of the vertical shaft 3c of the door body 3 through a vertical shaft 12 so as to be rotatable in the horizontal direction, and the mounting receiving seat 11 and the operating member The long plate-like operation part 10a always returns to the position facing the outer wall surface of the bathroom door X by the spring member 13 built in the combination part with the door 10.
[0015]
When the operation member 10 of the present invention presses the long plate-like operation part 10a against the outer wall surface side of the inner door 4, the latch 9 is retracted from the front surface, while when the hand is released from the long plate-like operation part 10a, The operating member 10 is restored by the spring force of the spring member 13, and the latch 9 protrudes from the front surface by the spring force of the latch spring 41. The point latch 9 is interlocked with the operation of the operation member 10 in the same manner as an ordinary lever handle.
[0016]
In the event of an emergency, the operating member 10 first slides the stopper piece 50 that engages with the engaging portion 20 of the fitting port portion 17 of the mounting receiving seat 11 horizontally toward the mounting receiving seat 11, and then the door body 3. When the engagement of the locking means 6 with the middle door 4 is released and the middle door 4 is opened to the undressing room B side, it rotates horizontally to the undressing room B side so as not to obstruct it. At this time, the latch 9 of the door body 3 is not interlocked (contracted) with the horizontal rotation of the operation member 10. When the hand is released from the long plate-like operation portion 10a, the operation member 10 returns to the original position by the spring force of the spring member 13.
[0017]
Then, the member relevant to the operation member 10 of this invention and the operation member 10 are further demonstrated. First, the configuration of the mounting seat 11 is shown. As shown in FIG. 4, a long seat type is used for the mounting seat 11. That is, 15 is a vertically long mounting board portion, and a pair of small holes 16 for fixing tools are formed above and below the mounting board portion 15. Reference numeral 17 denotes a rectangular fitting (mouth) portion formed continuously at the center of the mounting substrate portion 15, and a pair of shaft holes 18 for the vertical shaft 12 are formed in the fitting port portion 17.
[0018]
Thus, the attachment receiving seat 11 is formed in a rectangular tube shape penetrating from the fitting opening 17 to the attachment substrate portion 15, and as shown in FIG. 6, one inner wall portion 15a of the attachment substrate portion 15 is slightly meaty. It is formed in a thick shape. The inner wall surface of the inner wall portion 15a is arcuate from the inner side of the fitting port portion 17 to the inner opening on the latch 9 side, and somewhat closes the inner opening.
[0019]
Recessed opposing grooves 19, 19 are formed at the ends of the upper and lower walls 17 a, 17 b of the fitting opening portion 17 near the mounting substrate portion 15, respectively. , 19 are orthogonal to the mounting substrate portion 15. A plurality of protruding engaging portions 20 and 20 parallel to the mounting substrate portion 15 are provided on the bottom surfaces of the inner walls of the upper and lower opposing grooves 19 and 19 with a predetermined interval, as shown in FIG. ing.
[0020]
Next, the characteristics of the operation member 10 are well shown in FIG. 5, for example. Therefore, on the basis of FIG. 5, 10a is a long plate-like operation portion as described above, and a horizontal projection with a predetermined interval is provided at one end (right) portion of the inner wall surface of the operation portion 10a. A pair of plates 21 are provided. These upper and lower protrusion plates 21 are in contact with a stopper piece 50 slidably provided in the fitting port portion 17 so that the operation member 10 does not rotate toward the undressing room in normal times, and a decorative plate in appearance. As an aesthetic function.
[0021]
Therefore, the upper and lower protruding plates 21 are attached from the decorative plate portions 21a and 21a that protrude horizontally from the inner wall surface of the operation portion 10a in this embodiment, and from the portions near the ends of the decorative plate portions 21a and 21a. And a protrusion 21b extending in the direction of the mounting substrate portion 15 of the receiving seat 11.
[0022]
Reference numeral 22 denotes a case-like rotating portion that protrudes from the inner wall surface of the operation portion 10a so as to be positioned in the upper and lower protruding plates 21 and 21 and is fitted (fitted) into at least the fitting opening 17 of the mounting receiving seat 11. It is. The rotating part 22 is connected in a fist-like manner to the continuous support part 23 extending in a human wrist shape from one end of the inner wall surface of the operation part 10a, and to the continuous support part 23. Further, it comprises a base end portion 30a of an arm-like drive piece 30 for interlocking the latch 9 and a case-like portion 25 of a partial opening 24 that substantially houses the spring member 13 for returning the operation member 10.
[0023]
Thus, pivot holes 32 and 32 for the vertical shaft 12 are formed at the center of the upper and lower stepped horizontal plate portions 25b and 25b that are opposed to the vertical wall portion 25a of the case-like portion 25 in the crossing direction. Has been. In addition, considering the shape of the spring member 13 at appropriate locations on the inner wall surfaces of the upper and lower horizontal plate portions 25b, 25b, a storage space in which the upper and lower ring-shaped portions 13a, 13a of the spring member 13 should be reasonably positioned is formed. Angle-shaped step portions 25c, 25c for use are formed along the inner wall surface. An engagement notch 26 that locks the lower end portion 13b of the spring member 13 is formed at an appropriate portion of the case-like portion 25 (for example, a side end portion of the vertical wall portion 25a).
[0024]
Next, the spring member 13 for returning the operation member 10 and the drive piece 30 for retracting the latch 9 will be described. As shown in FIG. 6, the spring member 13 is attached to the drive piece 30 so that the upper and lower ring-shaped portions 13a and 13a are aligned with the vertical shaft hole 35 formed in the base end portion 30a of the drive piece 30. It is assembled in the rotating part 22 of the operating member 10 in a state. At that time, the lower end portion 13 b is locked to the engagement notch portion 26 of the rotating portion 22, while the upper end portion 13 c is in pressure contact with the inner wall surface of the mounting receiving seat 11. A U-shaped intermediate portion 13d connecting the upper and lower ring-shaped portions 13a and 13a abuts on one side (vertical) surface of the arm-shaped drive portion 30b of the drive piece 30. And the front-end | tip part of the arm-shaped drive part 30b protrudes from the inner side opening of the attachment receiving seat 11, and it engages with the rotation lever (driven piece) 40 which comprises the latch retracting mechanism Y, as shown in FIG.
[0025]
Here, with reference to FIG. 10, each member constituting the latch retracting mechanism Y will be briefly described. 41 is a latch spring that urges the latch 9 to always protrude from the front plate 42, 43 is a spring receiving plate that receives one end of the latch spring 41, and 44 is an L-shape interposed between the spring receiving plate 43 and the rotating lever 40. One end portion 44 a of the engagement rotation piece 44 is engaged with a latch engagement portion 45 formed or provided at the rear end portion of the latch 9. Further, the other end 44 b of the engaging rotating piece 44 is engaged with the rotating lever 40.
[0026]
Finally, the elastic stopper piece 50 will be described. The stopper piece 50 has a stopper function for restricting the operation member 10 from rotating to the undressing chamber B side in a normal state. In this embodiment, the stopper piece 50 is slid horizontally in the fitting port portion 17 of the attachment receiving seat 11. It is provided to be movable.
[0027]
Thus, the stopper piece 50 of the present embodiment is an end face lip groove-shaped elastic engagement / disengagement member having upper and lower engagement claw pieces 52, 52 as shown in FIG. The upper and lower engaging portions 20, 20 provided in the 17 opposing grooves 19 can be engaged and disengaged. The tip portions of the engaging claw pieces 52 and 52 are cut out in an arc shape because the corresponding engaging portion 20 is a horizontal bar-like protrusion.
[0028]
In the above configuration, when the bathroom door X is to be opened to the bathroom A side during normal times, the operation portion 10a of the operation member 10 is pushed to the middle door 4 side as shown in FIG. In this case, the operation member 10 rotates to a position where one end portion of the decorative plate portion 21 a of the projection plate 21 contacts the side wall surface of the stopper piece 50. That is, in normal times, as shown in FIGS. 2 and 3, one end of the decorative plate portion 21a of the projection plate 21 is separated from the stopper piece 50, so that the operation member 10 is pushed toward the inner door 4 side. can do.
[0029]
Thus, when the operating member 10 is horizontally rotated inward with the vertical shaft 12 as a fulcrum against the spring force of the spring member 13, the arm shape provided so as to be supported by the case-like rotating portion 22 of the operating member 10. The tip of the drive piece 30 moves in the direction of the arrow as shown in FIG. As a result, the rotary lever 40 and the engaging rotary piece 44 constituting the latch retracting mechanism Y rotate in the directions of the arrows (clockwise / counterclockwise), respectively. As a result, the latch 9 is guided by the latch guide plate 46, and Then, it is retracted against the spring force of the latch spring 41. Therefore, the bathroom door X can be opened as it is.
[0030]
On the other hand, when the middle door 4 of the bathroom door X is opened from the door body 3 in an emergency, first, the locking piece 7 of the engaging means 6 is removed from the engaging receiving piece 8, and as indicated by the arrow in FIG. Then, the stopper piece 50 is manually slid toward the mounting substrate portion 15 of the mounting seat 11. At this time, since the stopper piece 50 is an elastic engagement / disengagement member, the outward expansion displacement is repeated somewhat, and the engagement portion 20 on the operation member 10 side shifts to the engagement portion 20 on the mounting substrate portion 15 side. As a result, the stopper piece 50 is in a state of escaping from the protruding portion 21b of the protruding plate 21 of the operating member 10, and the operating member 10 can be pulled outward (on the dressing room B side) as shown in FIG.
[0031]
Therefore, as shown in FIG. 12, a hand (for example, a right hand) is put on the handle 4a of the middle door 4, and the middle door 4 is pulled to the near side. At this time, the other hand (for example, the left hand) is inserted inside the operation portion 10a of the operation member 10 and pulled outward. When the operation member 10 is pulled outward with the other hand, the operation member 10 moves horizontally against the spring force of the spring member 13 and moves away from the inner door 4. Therefore, when the middle door 4 is opened with respect to the door body 3 in this way, the operation member 10 does not become an obstacle at all. When the middle door 4 is opened to a desired state and then released from the operation unit 10 a, the operation member 10 is restored by the spring force of the spring member 13.
[0032]
【Example】
First, in the first embodiment, the mounting positions of the bar-shaped locking piece 7 and the hook-shaped engagement receiving piece 8 constituting the engaging means 6 may be reversed. Further, the spring member 13 for returning the operation member 10 is composed of a single spring wire, and returns even if the operation member 10 is horizontally rotated (push and pull) in any direction (inside the door and the dressing room). Although the force works, it may be composed of two spring wires depending on the design. Moreover, the protrusion-like engaging part 20 provided in the upper and lower opposing grooves 19 may be one each.
[0033]
Next, a second embodiment of the present invention will be described with reference to FIGS. In the description of the second embodiment, parts having the same configuration as in the first embodiment described above are denoted by the same or similar reference numerals, and redundant description is omitted.
[0034]
First, in the second embodiment, when the stopper piece 50A is moved in the horizontal direction, the stopper piece 50A is smoothly engaged with the plurality of engaging members 20A provided in the fitting port portion 17A so as to be vertically movable. It aims to be able to escape. The stopper piece 50A of the second embodiment is not necessarily an elastic member like the stopper piece 50 of the first embodiment.
[0035]
Thus, the engaging member 20A is constantly urged in the outward (engagement) direction by the small springs 61 respectively provided in the opposing grooves 19A. In this embodiment, the upper and lower walls 17a of the fitting port portion 17A, The engaging flange portion 20a is engaged with the bottom surface of the inner wall of the opposing groove 19A formed on the opposite groove 17b, and the engaging projection portion 20b is provided continuously with the engaging flange portion 20a. Then, the engagement protrusion 20b of each engagement member 20A engages with the engagement claw piece 52 of the stopper piece 50A as shown in FIG.
[0036]
In the above configuration, when the stopper piece 50A is moved in the horizontal direction, the upper and lower engaging members 20A retreat inward of the fitting opening 17A against the spring force of the small spring 61, respectively. Therefore, the object of the invention described above can be achieved.
[0037]
【The invention's effect】
As is clear from the above description, the present invention has the following effects.
(1) The rescue middle door that has been disengaged from the engagement means in an emergency can be opened by rotating it horizontally from the position to the dressing room side.
(2) When the operating member is pushed to the middle door side during normal operation, the latch is retracted to the front surface in conjunction with the operating member. Only the operating member rotates horizontally without being linked to the operating member. Therefore, the operation member is usually used as a general lever handle, while it can be used as a means for smoothly opening the middle door in an emergency.
(3) The lever-like operation member can be easily assembled in the mounting seat of the door body, and the operation member can be rotated horizontally (push and pull) in any direction (in the middle door side and the dressing room side). It returns to the position facing the outer wall surface of the bathroom door by the spring force of the spring member.
(4) Since the operation member does not rotate to the dressing room side during normal times, there is no inconvenience in use. In an emergency, the rotation of the operating member can be easily canceled by sliding the stopper piece.
(5) According to the invention described in claim 3, the stopper piece 50A can be smoothly moved in the horizontal direction, and the stopper piece 50A can be reliably stopped at a predetermined position even after being moved.
