【発明の属する技術分野】
本発明は乗場戸インタロック用係合ローラとかご戸インタロック解除用係合部材との係合外れを検出して自動復帰を行うかご戸係合部材の係合外れ復帰装置、及び係合外れを検出してかご内利用者に報知するかご戸係合部材の係合外れ報知装置に関する。
【０００２】
【従来の技術】
一般にエレベータ装置では、かごが停止していない時に乗場戸だけが単独で開閉する危険を避けるために、乗場戸インタロック用係合ローラとこのインタロックを解除するためにかご戸に設けられたかご戸インタロック解除用係合部材とが備えられていて、これらが係合しなければ乗場戸の開閉ができないようにしている。
【０００３】
この従来の乗場戸インタロック装置では、図１７及び図１８に示すように、かご戸１にはアングル２によってかご戸インタロック解除用係合部材３が取り付けられ、乗場戸４にはこのかご戸インタロック解除用係合部材３と両側から係合する乗場戸インタロック用Ａ係合ローラ５、Ｂ係合ローラ６が取り付けられている。
【０００４】
そしてエレベータ制御装置からのかご戸開閉指令によってかご戸１が開動作を開始した時には、図１８に実線で示した状態からかご戸１が左側へ動き始めることによってかご戸インタロック解除用係合部材３が乗場戸インタロック用Ｂ係合ローラ６に当接し、この押圧力でＢ係合ローラ６が若干スイングし、これに連動してＡ係合ローラ５もスイングしてかご戸インタロック解除用係合部材３に後側（図１８において右側から左側へ動いて鎖線で示す状態で係合部材３の右側面に係合し、このＡ係合ローラ５の動作で接点（図示せず）が反転動作して乗場戸４のインタロックを外し、かご戸１の動きに連動して乗場戸４が共に開き始める。
【０００５】
乗場戸４とかご戸１とが閉じる際には、図１８に鎖線で示した状態までかご戸１と乗場戸４が左側から右側へ動くと、まず乗場戸４が全閉状態になって停止し、これと共に乗場戸４に固定されているＢ係合ローラ６が先に停止し、かご戸１だけがさらに右側へ移動することによってＢ係合ローラ６からＡ係合ローラ５とかご戸インタロック解除用係合部材３が離れて、かご戸１は実線で示す全閉状態に戻る。Ａ係合ローラ５が図１８で実線で示す元の位置まで復帰すると乗場戸インタロック解除信号の出力が停止し、エレベータ制御装置は乗場戸インタロックをかける。またかご戸１の全閉を検出するスイッチが動作してかご戸１の全閉信号をエレベータ制御装置に出力する。
【０００６】
この乗場戸インタロック装置は、戸の安全装置の１つで、各階乗場戸に設けられていて、かごが停止してかご戸が開き始めなければ乗場戸の開閉ができないようにして、かごが停止していない階床の乗場側から乗場戸が開かれ、昇降路に誤って人が落ち込まないようにするものである。
【０００７】
ところが、利用者がいたずらなどでかご戸を無理に開けたり、戸開の状態で台車による荷物の出し入れの際にかご戸に設けられている戸開装置（ドアセーフティ）に台車をぶつけた場合には、図１９に示すようにかご戸インタロック解除用係合部材３が乗場戸インタロック用Ａ，Ｂ係合ローラ５，６間からＢ係合ローラ６の左側（かご戸１の開く方向）に外れてしまうことが起こり得る。また台車を乗場戸にぶつけたりして全開している乗場戸にさらに開かせようとする無理な力が加わったり、逆に全開状態でかご戸１に無理に閉じようとする力が加えられた時には、図２０に示すように乗場戸インタロック用Ａ，Ｂ係合ローラ５，６間からＡ係合ローラ５の右側にかご戸インタロック解除用係合部材３が外れてしまうことも起こる。
【０００８】
図１９に示すような係合外れ状態になった時にはかご戸１と乗場戸４とが一緒に閉じて来ると乗場戸４が先に全閉状態になるが、Ｂ係合ローラ６の左側（閉じる方向の後側）に係合部材３が引掛ったままになっているためにかご戸１が全閉状態まで閉まることができなくなり、いつまで待ってもエレベータを発車させることができなくなる。
【０００９】
また図２０に示すような係合外れ状態になった時には、かご戸１と乗場戸４とが一緒に閉じて来るとかご戸１が先に全閉状態になるが、Ａ係合ローラ５の右側（閉じる方向の前側）に係合部材３が引掛ったままになっているために乗場戸４が全閉状態まで閉まることができなくなり、エレベータを発車させることができなくなる。
【００１０】
【発明が解決しようとする課題】
上述したように、従来の乗場戸インタロック装置では、いったんかご戸インタロック解除用係合部材３が乗場戸インタロック用Ａ，Ｂ係合ローラ５，６間の位置から外れてしまうと、それを自動的に正規の位置に復帰させる手段を備えていなかったために人手によって係合外れを復帰させなければエレベータを発車させることができず、いつまでも停止したままになる問題点があった。
【００１１】
本発明はこのような従来の問題点に鑑みてなされたもので、何らかの原因でかご戸インタロック解除用係合部材が乗場戸インタロック用Ａ，Ｂ係合ローラ間から外れた時に自動的に係合外れを復帰させることができるかご戸係合部材の係合外れ復帰装置を提供することを目的とする。
【００１２】
本発明はまた、上記係合外れが発生した時にかご内利用者に係合外れの発生を報知することができる係合外れ報知装置を提供することも目的とする。
【００１３】
【課題を解決するための手段】
請求項１の発明のかご戸係合部材の係合外れ復帰装置は、かご戸にかご戸インタロック解除用係合部材が取り付けられ、乗場戸に前記かご戸インタロック解除用係合部材に対して全閉位置側とその反対側とから係合する乗場戸インタロック用Ａ係合ローラ、Ｂ係合ローラが取り付けられ、前記かご戸インタロック解除用係合部材が前記乗場戸インタロック用Ｂ係合ローラに当接させ、この押圧力でＢ係合ローラを通過させ、さらに、前記Ａ係合ローラを前記かご戸インタロック解除用係合部材に後側から係合させ、この状態で前記乗場戸のインタロックを外し、前記乗場戸をかご戸と連動して開動させ、乗場戸インタロック解除信号を出力する乗場戸インタロック装置と、前記乗場戸インタロック解除信号と外部からのかご戸閉信号とのいずれか一方の信号のみが入力される時に前記乗場戸インタロック用Ａ係合ローラ若しくはＢ係合ローラと係合部材との係合外れ発生を検出する係合外れ検出手段と、前記かご戸インタロック解除用係合部材を起倒駆動する吸引装置によって、前記係合部材を正規の位置で前記かご戸に対して直立するように支持し、かつ、前記係合外れ検出信号を受けると前記係合部材を引き倒すことによって当該係合部材と前記Ａ係合ローラ若しくはＢ係合ローラとの係合を外し、前記かご戸若しくは乗場戸を全閉位置まで移動させ、その後に前記係合部材を直立する正規の状態まで復帰させる係合外れ復帰手段とを備えたものである。
【００１４】
この請求項１の発明のかご戸係合部材の係合外れ復帰装置では、乗場戸インタロック用係合ローラとかご戸インタロック解除用係合部材との係合外れが発生した時には、係合外れ検出手段が係合外れを検出し、さらに係合外れ復帰手段がこの係合外れ検出を受けて乗場戸インタロック用係合ローラとかご戸インタロック解除用係合部材との係合外れを復帰させる。これによってかご戸係合部材の係合外れの発生時に自動的にその復帰ができて、乗場戸がいつまでも閉じなくてエレベータの起動ができなくなる事態の発生を防止することができる。
【００１７】
請求項２の発明のかご戸係合部材の係合外れ復帰装置は、かご戸にかご戸インタロック解除用係合部材が取り付けられ、乗場戸に前記かご戸インタロック解除用係合部材に対して全閉位置側とその反対側とから係合する乗場戸インタロック用Ａ係合ローラ、Ｂ係合ローラが取り付けられ、前記かご戸インタロック解除用係合部材が前記乗場戸インタロック用Ｂ係合ローラに当接させ、この押圧力でＢ係合ローラを通過させ、さらに、前記Ａ係合ローラを前記かご戸インタロック解除用係合部材に後側から係合させ、この状態で前記乗場戸のインタロックを外し、前記乗場戸をかご戸と連動して開動させ、乗場戸インタロック解除信号を出力する乗場戸インタロック装置と、前記乗場戸インタロック解除信号と外部からのかご戸閉信号とのいずれか一方の信号のみが入力される時に前記乗場戸インタロック用Ａ係合ローラ若しくはＢ係合ローラと係合部材との係合外れ発生を検出する係合外れ検出手段と、前記かご戸インタロック解除用係合部材を起倒駆動する吸引装置によって、前記係合部材を正規の位置で前記かご戸に対して直立するように支持し、かつ、前記係合外れ検出信号を受けると前記係合部材を引き倒すことによって当該係合部材と前記Ａ係合ローラ若しくはＢ係合ローラとの係合を外し、前記かご戸若しくは乗場戸を全閉位置まで移動させ、その後に前記係合部材を直立する正規の状態まで復帰させる係合外れ復帰手段と、前記係合外れ検出手段が前記係合外れを検出した時に当該係合外れの発生を報知する、かご内に設置された係合外れ報知手段とを備えたものである。
【００１８】
この請求項２の発明のかご戸係合部材の係合外れ復帰装置では、請求項１の発明のように乗場戸インタロック用係合ローラとかご戸インタロック解除用係合部材との係合外れが発生した時には、係合外れ検出手段が係合外れを検出し、さらに係合外れ復帰手段がこの係合外れ検出を受けて乗場戸インタロック用係合ローラとかご戸インタロック解除用係合部材との係合外れを復帰させる。そしてこれと共に、係合外れを検出した時には、かご内に設置された係合外れ報知手段がこの係合外れをかご内の利用者に報知し、利用者の不安を解消する。
【００１９】
請求項３の発明は、請求項１または２のかご戸係合部材の係合外れ復帰装置においてさらに、前記かご戸インタロック解除用係合部材の破損を検出する破損検出手段と、前記破損検出手段が前記かご戸インタロック解除用係合部材の破損を検出した時に、前記係合外れ復帰手段の動作を禁止する復帰動作禁止手段とを備えたものである。
【００２０】
この請求項３の発明のかご戸係合部材の係合外れ復帰装置では、乗場戸インタロック用係合ローラとかご戸インタロック解除用係合部材との係合外れと、かご戸インタロック解除用係合部材の破損とを区別して検出し、かご戸インタロック解除用係合部材の破損を検出した時には係合外れ復帰手段による自動復帰動作を禁止し、本来のインタロック機能を維持させて二次災害を防止する。
【００２１】
請求項４の発明は、請求項１または２のかご戸係合部材の係合外れ復帰装置においてさらに、前記かご戸インタロック解除用係合部材の破損を検出する破損検出手段と、前記破損検出手段が前記かご戸インタロック解除用係合部材の破損を検出した時に、前記係合外れ復帰手段の動作を禁止する復帰動作禁止手段と、前記破損検出手段が前記かご戸インタロック解除用係合部材の破損を検出した時に、当該係合部材破損の発生を報知する、前記かご内に設置された破損発生報知手段とを備えたものである。
【００２２】
この請求項４の発明のかご戸係合部材の係合外れ復帰装置では、乗場戸インタロック用係合ローラとかご戸インタロック解除用係合部材との係合外れと、かご戸インタロック解除用係合部材の破損とを区別して検出し、かご戸インタロック解除用係合部材の破損を検出した時には係合外れ復帰手段による自動復帰動作を禁止し、本来のインタロック機能を維持させて二次災害を防止する。これと共に、破損発生報知手段によって係合部材の破損発生をかご内の利用者に報知して、利用者の不安を解消する。
【００２３】
【発明の実施の形態】
以下、本発明の実施の形態を図に基づいて詳説する。図１は本発明の第１の実施の形態の機能構成を示しており、乗場戸インタロック装置１１からの乗場戸閉信号１２と、かご戸装置１３からのかご戸閉信号１４とを入力し、これらの信号の組み合わせで係合外れを判定する係合外れ検出回路１５と、この係合外れ検出回路１５からの係合外れ検出信号１６に基づき動作する係合外れ復帰装置１７を備えている。
【００２４】
乗場戸インタロック装置１１は、図１７〜図２０に示した従来例と同様の構成、機能を有していて、エレベータ制御装置からのかご戸開閉指令によってかご戸１が開動作を開始した時には、図１８に実線で示した状態からかご戸１が左側へ動き始めることによってかご戸インタロック解除用係合部材３が乗場戸インタロック用Ｂ係合ローラ６に当接し、この押圧力でＢ係合ローラ６が若干スイングし、これに連動してＡ係合ローラ５もスイングしてかご戸インタロック解除用係合部材３に後側（図１８において右側から左側へ動いて鎖線で示す状態で係合部材３の右側面に係合し、このＡ係合ローラ５の動作で接点（図示せず）が反転動作した時にインタロックを解除してかご戸１と乗場戸４とが一緒に開閉動作可能とする機能を有している。また乗場戸インタロック装置１１は、従来から広く用いられている手段、例えば、乗場戸４が全閉状態になった時にその乗場戸４と共に動く接点当接要素（図示せず）が乗場戸口の固定部に取り付けられている全閉検出スイッチ（図示せず）の可動接点に当接してスイッチを反転動作させた時に乗場戸閉信号１２を出力する機能を有している。
【００２５】
かご戸装置１３はかご戸１を開閉駆動する装置であり、従来から広く用いられている手段、例えば、かご戸１が全閉状態になった時にそのかご戸１と共に動く接点当接要素（図示せず）がかごの固定部に取り付けられている全閉検出スイッチ（図示せず）の可動接点に当接してスイッチを反転動作させた時にかご戸閉信号１４を出力する。
【００２６】
係合外れ検出回路１５は、図１９に示した状態、つまり乗場戸閉信号１２が入力されているのにかご戸閉信号１４が入力されない場合、また図２０に示した状態、つまりかご戸閉信号１４が入力されているのに乗場戸閉信号１４が入力されない場合に乗場戸インタロック用Ａ，Ｂ係合ローラ５，６とかご戸インタロック解除用係合部材３との係合外れが発生したと判定し、係合外れ信号１６を出力する。
【００２７】
係合外れ復帰装置１７は図２及び図３に示す機械的な構成であり、かご戸１に取り付けられた、かご戸インタロック解除用係合部材３を起倒駆動するための油圧式あるいは電磁式の吸引装置２１と、この吸引装置２１により吸引、押出駆動されるプランジャ２２と、かご戸インタロック解除用係合部材３の起倒動作をガイドするガイドレール２３と、このガイドレール２３に沿ってスライドするガイドシュー２４とから構成されている。なお、２５は固定アングルであり、係合部材３を正規の位置でかご戸１に対して垂直に直立するように支持する。
【００２８】
この係合外れ復帰装置１７は、図２及び図３に示す正規の状態において、後述する係合外れ復帰信号１６を受けると図５及び図７に示すように吸引装置２１を駆動してプランジャ２２を吸引し、これによって係合部材３の根本部分を吸引装置２１側に引き寄せて倒し、係合部材３の先端部分を乗場戸４側のＡ，Ｂ係合ローラ５，６よりもかご戸１側に近づかせることにより、かご戸１と乗場戸４とが相対的に移動できるようにし、またこの後に吸引装置２１によってプランジャ２２を元の位置まで押し出して、係合部材３を図２及び図３に示す正規の状態まで起こす動作をすることができる。
【００２９】
次に、上記構成のかご戸係合部材の係合外れ復帰装置の動作について説明する。図２及び図３に示すようにかご戸１と乗場戸４が共に全閉状態から、かご戸開閉指令によってかご戸１が開動作を開始した時には、従来例と同様に、図１８に実線で示した状態からかご戸１が左側へ動き始めることによってかご戸インタロック解除用係合部材３が乗場戸インタロック用Ｂ係合ローラ６に当接し、この押圧力でＢ係合ローラ６が若干スイングし、これに連動してＡ係合ローラ５もスイングしてかご戸インタロック解除用係合部材３に後側（図１８において右側から左側へ動いて鎖線で示す状態で係合部材３の右側面に係合し、このＡ係合ローラ５の動作で接点（図示せず）が反転動作して乗場戸４のインタロックを外し、かご戸１の動きに連動して乗場戸４が共に開き始める。
【００３０】
また乗場戸４とかご戸１とが閉じる際には、図１８に鎖線で示した状態までかご戸１と乗場戸４が左側から右側へ動いてくると、まず乗場戸４が全閉状態になって停止し、これと共に乗場戸４に固定されているＢ係合ローラ６が先に停止し、かご戸１だけがさらに右側へ移動することによってＢ係合ローラ６からＡ係合ローラ５とかご戸インタロック解除用係合部材３が離れて、かご戸１は実線で示す全閉状態に戻る。Ａ係合ローラ５が図１８で実線で示す元の位置まで復帰すると乗場戸インタロック解除信号の出力が停止し、エレベータ制御装置は乗場戸インタロックをかける。またかご戸１の全閉を検出するスイッチが動作してかご戸１の全閉信号をエレベータ制御装置に出力する。
【００３１】
ところが、利用者がいたずらなどでかご戸を無理に開けたり、戸開の状態で台車による荷物の出し入れの際にかご戸に設けられている戸開装置（ドアセーフティ）に台車をぶつけたりして、図４に示すようにかご戸インタロック解除用係合部材３が乗場戸インタロック用Ａ，Ｂ係合ローラ５，６間からＢ係合ローラ６の左側（かご戸１の開く方向）に外れてしまうと、かご戸１と乗場戸４とが一緒に閉じて来ると乗場戸４が先に全閉状態になるが、Ｂ係合ローラ６の左側（閉じる方向の後側）に係合部材３が引掛ったままになっているためにかご戸１が全閉状態まで閉まることができなくなる。
【００３２】
この時、図１において乗場戸インタロック装置１１から乗場戸閉信号１２が出力されるが、かご戸装置１３からはかご戸閉信号１４が出力されない。このため、係合外れ検出回路１５は係合外れ検出信号１６を係合外れ復帰装置１７に出力する。
【００３３】
係合外れ復帰装置１７は、係合外れ検出信号１６を受けると、図５に示すように吸引装置２１を駆動してプランジャ２２を吸引して係合部材３を倒す。これによって係合部材３の先端部分がＢ係合ローラ６との引掛りから外れ、かご戸１は全閉位置まで移動できるようなり全閉状態まで移動する。そこで、吸引装置２１によりプランジャ２２を押し出して係合部材３を直立する正規の状態まで復帰させることにより、係合部材３が乗場戸インタロック用Ａ，Ｂ係合ローラ５，６間に位置するようになり、係合外れから復帰できる。
【００３４】
また逆に図６に示すような係合外れ状態になった時には、かご戸１と乗場戸４とが一緒に閉じて来るとかご戸１が先に全閉状態になるが、Ａ係合ローラ５の右側（閉じる方向の前側）に係合部材３が引掛ったままになっているために乗場戸４が全閉状態まで閉まることができなくなる。
【００３５】
この時には、図１において乗場戸インタロック装置１１から乗場戸閉信号１２が出力されず、かご戸装置１３からかご戸閉信号１４が出力されるようになるため、係合外れ検出回路１５は係合外れ検出信号１６を出力する。そこで、係合外れ復帰装置１７は、図７に示すように吸引装置２１を駆動してプランジャ２２を吸引して係合部材３を倒し、係合部材３の先端部分がＡ係合ローラ５との引掛りから外れ、乗場戸４を全閉位置まで移動させ、この後に吸引装置２１によりプランジャ２２を押し出して係合部材３を直立する正規の状態まで復帰させ、係合部材３を乗場戸インタロック用Ａ，Ｂ係合ローラ５，６間に位置させ、係合外れから復帰させる。
【００３６】
以上の動作の制御を図８のフローチャートで説明すると、乗場戸３の全閉信号１２とかご戸１の全閉信号１４のどちらかが入力されない場合に、係合外れ検出回路１５が係合外れを検出し（ステップＳ１）、係合外れ復帰装置１７が起動されて上述した係合外れ復帰動作をしてかご戸インタロック解除用係合部材３と乗場戸インタロック用Ａ，Ｂ係合ローラ５，６との係合外れを自動的に復帰させて、エレベータを発車できるようにするのである（ステップＳ２）。
【００３７】
次に、本発明の第２の実施の形態のかご戸係合部材の係合外れ報知装置を図９及び図１０に基づいて説明する。この第２の実施の形態の特徴は、係合外れ検出回路１５が乗場戸インタロック用Ａ，Ｂ係合ローラ５，６とかご戸インタロック解除用係合部材３との係合外れを検出した時に、この係合外れ検出信号１６によって、例えば、「かご戸の係合が外れました。非常ボタンを押してください。」といった放送を行うかご内報知装置１８をかご内に設置した点にある。
【００３８】
この第２の実施の形態によれば、図１０のフローチャートに示すように、第１の実施の形態と同様に図４または図６の係合外れが発生し、係合外れ検出回路１５が係合外れを検出した時には（ステップＳ１１）、かご内報知装置１８によって利用者に係合外れを放送し、利用者の不快感、不安感を抑える（ステップＳ１２）。
【００３９】
なお、かご内報知装置１８としては、スピーカによって音声による報知を行う代わりに、あるいは同時にかご内に設置されているディスプレイに表示する手段を採用することもできる。
【００４０】
また、上記の第１と第２の実施の形態との機能を共に有するものとして、図１１に示すかご戸係合部材の係合外れ復帰装置を構成することもできる。この第３の実施の形態のかご戸係合部材の係合外れ復帰装置では、係合外れ検出回路１５が係合外れを検出して係合外れ検出信号１６を出力する時に、係合外れ復帰装置１７によって係合外れの復帰動作をすると共に、かご内報知装置１８によって、「かご戸の係合外れが発生しました。復旧しますので、しばらくお待ちください。」といった案内放送をかご内に流すことによって利用者の不快感、不安感を抑えることができる。
【００４１】
次に、本発明の第４の実施の形態のかご戸係合部材の係合外れ復帰装置を図１２〜図１４に基づいて説明する。第４の実施の形態は、係合外れ検出回路１５と共にかご戸インタロック解除用係合部材３の破損を検出するかご戸係合部材破損検出装置１９をかご戸１に設け、第１、第２の実施の形態で係合外れ検出回路１５が係合外れ検出信号１６を出力する場合でも、かご戸係合部材検出装置１９がかご戸インタロック解除用係合部材３の破損を検出した時には係合外れ検出信号１６を出力しないようにしたことを特徴とする。
【００４２】
図１３に示すようにかご戸係合部材破損検出装置１９は、かご戸インタロック解除用係合部材３にかご戸１との間の距離Ｇを計測するギャップセンサ２７を備え、このギャップセンサ２７が検出する距離Ｇが規定値よりも大きくずれた場合にかご戸係合部材破損検出信号１１０を出力する働きをする。例えば、かご戸インタロック解除用係合部材３が何かの部材に引掛り、大きく変形したり、脱落したりすると、ギャップセンサ２７の検出するかご戸１までの距離Ｇは規定値から大きく変化する。そこで、かご戸係合部材破損検出装置１９はこのギャップセンサ２７からの距離計測信号を受けて、規定値と比較して大きなずれが発生している時にかご戸係合部材破損検出信号１１０を出力するのである。
【００４３】
そこで、第４の実施の形態のかご戸係合部材の係合外れ復帰装置は、図１４のフローチャートに示すように動作する。乗場戸閉信号１２またはかご戸閉信号１４のどちらか一方だけが入力されることによって、係合外れ検出回路１５は係合外れと判定するが（ステップＳ２１）、この時にはさらに、係合部材破損検出信号１１０の入力の有無を判定し（ステップＳ２２）、破損検出信号１１０が入力されていなければ本当に係合外れが発生していると判断して係合外れ信号１６を係合外れ復帰装置１７に出力し、係合外れ復帰装置１７は第１の実施の形態と同じ動作によってかご戸インタロック解除用係合部材３の係合外れを復帰させる（ステップＳ２３）。
【００４４】
しかしながら、ステップＳ２２の判断で、係合部材破損検出装置１９が破損検出信号１１０を出力していれば係合外れ検出回路１５は係合外れ検出信号１６を出力しないようにして、係合外れ復帰装置１７の動作を禁止する。
【００４５】
これによって、かご戸インタロック解除用係合部材３が破損した結果として係合外れが発生している場合には、単なる係合外れと区別し、係合外れ復帰装置１７の動作で再係合させてエレベータを発車させると発生するかもしれない二次災害の発生を未然に防止する。
【００４６】
次に、本発明の第５の実施の形態のかご戸係合部材の係合外れ復帰装置を図１５及び図１６に基づいて説明する。この第５の実施の形態は、第４の実施の形態において、さらにかご内報知装置１８をも並設したことを特徴とする。すなわち、係合外れ検出回路１５と共にかご戸インタロック解除用係合部材３の破損を検出するかご戸係合部材破損検出装置１９をかご戸１に設け、またかご内報知装置１８をかご内に設置し、第１、第２の実施の形態で係合外れ検出回路１５が係合外れ検出信号１６を出力する場合でも、かご戸係合部材検出装置１９がかご戸インタロック解除用係合部材３の破損を検出した時には係合外れ検出信号１６を出力しないようにし、代わりにかご内報知装置１８には係合部材破損検出信号１１０を出力するようにしている。
【００４７】
この第５の実施の形態のかご戸係合部材の係合外れ復帰装置では、図１６のフローチャートに示すように、乗場戸閉信号１２またはかご戸閉信号１４のどちらか一方だけが入力されることによって、係合外れ検出回路１５は係合外れと判定するが（ステップＳ３１）、この時にはさらに、係合部材破損検出信号１１０の入力の有無を判定し（ステップＳ３２）、破損検出信号１１０が入力されていなければ本当に係合外れが発生していると判断して係合外れ信号１６を係合外れ復帰装置１７に出力し、係合外れ復帰装置１７は第１の実施の形態と同じ動作によってかご戸インタロック解除用係合部材３の係合外れを復帰させる（ステップＳ３３）。またかご内報知装置１８に対しても係合外れ検出信号１６を出力して、「かご戸の係合外れが発生しました。復旧しますので、しばらくお待ちください。」というような案内放送をして利用者の不快感、不安感をなくす（ステップＳ３４）。
【００４８】
一方、ステップＳ３２の判断で、係合部材破損検出装置１９が破損検出信号１１０を出力していれば係合外れ検出回路１５は係合外れ検出信号１６を出力しないようにして、係合外れ復帰装置１７の動作を禁止する。そしてこの場合にはかご内報知装置１８に係合部材破損検出信号１１０を出力し、かご内報知装置１８に「かご戸の係合装置の不具合が発生しました。非常ボタンを押してください。」といった案内放送を出力させる（ステップＳ３４）。
【００４９】
これによって、かご戸インタロック解除用係合部材３が破損した結果として係合外れが発生している場合には、単なる係合外れと区別し、係合外れ復帰装置１７の動作で再係合させてエレベータを発車させると発生するかもしれない二次災害の発生を未然に防止すると共に、そのような場合にも案内放送によって利用者が抱く不快感、不安感をなくすことができる。

It has a function of outputting a landing door closing signal 12 when the switch is reversed by contacting a movable contact of a fully-closed detection switch (not shown) attached to the fixed portion.
[0025]
The car door device 13 is a device that drives the car door 1 to open and close, and has been widely used, for example, a contact contact element that moves together with the car door 1 when the car door 1 is fully closed (see FIG. A car door closing signal 14 is output when a switch (not shown) abuts against a movable contact of a fully-closed detection switch (not shown) attached to a fixed portion of the car to reverse the switch.
[0026]
The disengagement detection circuit 15 is in the state shown in FIG. 19, that is, when the car door closing signal 14 is not input even though the landing door closing signal 12 is input, or in the state shown in FIG. When the signal 14 is input but the landing door closing signal 14 is not input, the disengagement between the landing door interlocking A and B engaging rollers 5 and 6 and the car door interlock releasing engaging member 3 is disengaged. It determines with having generate | occur | produced, and the disengagement signal 16 is output.
[0027]
The disengagement return device 17 has the mechanical configuration shown in FIGS. 2 and 3 and is hydraulic or electromagnetic for driving the car door interlock releasing engagement member 3 attached to the car door 1 upside down. Suction device 21, a plunger 22 that is driven to be sucked and pushed out by the suction device 21, a guide rail 23 that guides the raising / lowering operation of the car door interlock release engagement member 3, and the guide rail 23 And a guide shoe 24 that slides. Reference numeral 25 denotes a fixed angle, which supports the engaging member 3 so as to stand vertically upright with respect to the car door 1 at a regular position.
[0028]
When the disengagement return device 17 receives the disengagement return signal 16 described later in the normal state shown in FIGS. 2 and 3, the disengagement return device 17 drives the suction device 21 as shown in FIG. 5 and FIG. As a result, the root portion of the engagement member 3 is pulled toward the suction device 21 side and brought down, and the tip portion of the engagement member 3 is moved more than the A and B engagement rollers 5 and 6 on the landing door 4 side. By moving closer to the side, the car door 1 and the landing door 4 can move relative to each other, and after this, the plunger 22 is pushed out to the original position by the suction device 21, and the engaging member 3 is moved to the position shown in FIGS. 3 can be raised to a normal state.
[0029]
Next, the operation of the disengagement return device for the car door engaging member having the above-described configuration will be described. As shown in FIGS. 2 and 3, when the car door 1 and the landing door 4 are both fully closed and the car door 1 starts to open in response to the car door opening / closing command, as shown in FIG. When the car door 1 starts to move to the left from the state shown, the car door interlock releasing engagement member 3 comes into contact with the landing door interlock B engagement roller 6, and the B engagement roller 6 is slightly moved by this pressing force. Swinging, the A engagement roller 5 swings in conjunction with this, and the rear side of the engagement member 3 for releasing the car door interlock (moved from the right side to the left side in FIG. Engage with the right side, and the operation of this A engagement roller 5 reverses the contact (not shown) to release the interlock of the landing door 4, and the landing door 4 moves together with the movement of the car door 1. Start to open.
[0030]
When the door 4 and the car door 1 are closed, when the car door 1 and the car door 4 move from the left to the right until the state shown by the chain line in FIG. 18, the hall 4 is first fully closed. The B engaging roller 6 fixed to the landing door 4 is stopped first, and only the car door 1 is further moved to the right side to move the B engaging roller 6 to the A engaging roller 5 and the like. The door interlock release engaging member 3 is released, and the car door 1 returns to the fully closed state indicated by the solid line. When the A engagement roller 5 returns to the original position shown by the solid line in FIG. 18, the output of the landing door interlock release signal stops, and the elevator control device applies the landing door interlock. Further, a switch for detecting whether the car door 1 is fully closed operates to output a car door 1 fully closed signal to the elevator control device.
[0031]
However, the user forcibly opens the car door by mischief, or hits the car against the door opening device (door safety) provided in the car door when loading and unloading the car with the car open. As shown in FIG. 4, the car door interlock releasing engagement member 3 is located between the landing door interlock A and B engaging rollers 5 and 6 on the left side of the B engaging roller 6 (in the direction in which the car door 1 opens). If it comes off, when the car door 1 and the landing door 4 are closed together, the landing door 4 is first fully closed, but is engaged with the left side of the B engagement roller 6 (the rear side in the closing direction). Since the member 3 remains caught, the car door 1 cannot be closed to the fully closed state.
[0032]
At this time, in FIG. 1, the landing door closing signal 12 is output from the landing door interlock device 11, but the car door closing signal 14 is not output from the car door device 13. For this reason, the disengagement detection circuit 15 outputs the disengagement detection signal 16 to the disengagement return device 17.
[0033]
When receiving the disengagement detection signal 16, the disengagement return device 17 drives the suction device 21 to suck the plunger 22 and tilt the engagement member 3 as shown in FIG. 5. As a result, the distal end portion of the engaging member 3 is disengaged from the hook with the B engaging roller 6, and the car door 1 can be moved to the fully closed position and is moved to the fully closed state. Therefore, the plunger 22 is pushed out by the suction device 21 to return the engaging member 3 to the normal state in which the engaging member 3 stands upright, whereby the engaging member 3 is positioned between the landing door interlock A and B engaging rollers 5 and 6. Thus, it is possible to return from the disengagement.
[0034]
Conversely, when the car door 1 and the landing door 4 close together when the car door 1 and the landing door 4 are closed together as shown in FIG. 6, the car door 1 is first fully closed. Since the engaging member 3 remains hooked on the right side of 5 (the front side in the closing direction), the landing door 4 cannot be closed to the fully closed state.
[0035]
At this time, in FIG. 1, the landing door closing signal 12 is not output from the landing door interlock device 11, and the car door closing signal 14 is output from the car door device 13. A miss detection signal 16 is output. Therefore, the disengagement return device 17 drives the suction device 21 to suck the plunger 22 and tilt the engagement member 3 as shown in FIG. 7, and the distal end portion of the engagement member 3 is connected to the A engagement roller 5. The landing door 4 is moved to the fully closed position, and then the plunger 22 is pushed out by the suction device 21 to return the engaging member 3 to the normal state in which the engaging member 3 stands upright. It is positioned between the locking A and B engaging rollers 5 and 6, and is returned from the disengagement.
[0036]
The control of the above operation will be described with reference to the flowchart of FIG. 8. When either the fully closed signal 12 of the landing door 3 or the fully closed signal 14 of the car door 1 is not input, the disengagement detection circuit 15 is disengaged. Is detected (step S1), the disengagement return device 17 is activated to perform the disengagement return operation described above, and the car door interlock release engagement member 3 and the landing door interlock A and B engagement rollers. The disengagement with 5, 6 is automatically restored so that the elevator can be started (step S2).
[0037]
Next, a car door engagement member disengagement notification device according to a second embodiment of the present invention will be described with reference to FIGS. The feature of the second embodiment is that the disengagement detection circuit 15 detects disengagement between the A and B engaging rollers 5 and 6 for the landing door interlock and the engaging member 3 for releasing the car door interlock. In this case, the car disengagement detection signal 16 is provided with an in-car informing device 18 that broadcasts, for example, “The car door has been disengaged. Please press the emergency button.” .
[0038]
According to the second embodiment, as shown in the flowchart of FIG. 10, the disengagement of FIG. 4 or 6 occurs as in the first embodiment, and the disengagement detection circuit 15 is engaged. When the disengagement is detected (step S11), the disengagement and anxiety of the user are suppressed by broadcasting the disengagement to the user by the in-car notification device 18 (step S12).
[0039]
In addition, as the notification apparatus 18 in a car, a means for displaying on a display installed in the car can be employed instead of performing sound notification by a speaker or simultaneously.
[0040]
Further, the car door engaging member disengagement return device shown in FIG. 11 can be configured as having both the functions of the first and second embodiments. In the disengagement return device for the car door engaging member according to the third embodiment, the disengagement return is detected when the disengagement detection circuit 15 detects the disengagement and outputs the disengagement detection signal 16. The device 17 performs the disengagement return operation, and the in-car informing device 18 sends a guidance broadcast such as “There has been a disengagement of the car door. As a result, user discomfort and anxiety can be suppressed.
[0041]
Next, a car door engagement member disengagement return device according to a fourth embodiment of the present invention will be described with reference to FIGS. In the fourth embodiment, a car door engaging member breakage detecting device 19 that detects breakage of the car door interlock releasing engaging member 3 together with the disengagement detection circuit 15 is provided in the car door 1. Even when the disengagement detection circuit 15 outputs the disengagement detection signal 16 in the second embodiment, the car door engagement member detection device 19 detects the breakage of the engagement member 3 for releasing the car door interlock. The disengagement detection signal 16 is not output.
[0042]
As shown in FIG. 13, the car door engaging member breakage detecting device 19 includes a gap sensor 27 that measures the distance G between the car door interlock release engaging member 3 and the car door 1, and this gap sensor 27. It functions to output a car door engaging member breakage detection signal 110 when the detected distance G deviates more than a specified value. For example, if the engagement member 3 for releasing the car door interlock is caught by any member and greatly deforms or falls off, the distance G to the car door 1 detected by the gap sensor 27 greatly changes from the specified value. To do. Therefore, the car door engaging member breakage detection device 19 receives the distance measurement signal from the gap sensor 27 and outputs a car door engaging member breakage detection signal 110 when a large deviation occurs compared to the specified value. To do.
[0043]
Therefore, the disengagement return device for the car door engaging member according to the fourth embodiment operates as shown in the flowchart of FIG. When only one of the landing door closing signal 12 and the car door closing signal 14 is input, the disengagement detection circuit 15 determines that the engagement is disengaged (step S21). It is determined whether or not the detection signal 110 is input (step S22). If the breakage detection signal 110 is not input, it is determined that the disengagement has actually occurred, and the disengagement signal 16 is transmitted to the disengagement return device 17. And the disengagement return device 17 returns the disengagement of the car door interlock releasing engagement member 3 by the same operation as in the first embodiment (step S23).
[0044]
However, if it is determined in step S22 that the engagement member breakage detection device 19 has output the breakage detection signal 110, the disengagement detection circuit 15 does not output the disengagement detection signal 16 so that the disengagement is restored. The operation of the device 17 is prohibited.
[0045]
As a result, when disengagement occurs as a result of the car door interlock release engagement member 3 being damaged, it is distinguished from simple disengagement, and reengagement is performed by the operation of the disengagement return device 17. This will prevent the occurrence of secondary disasters that may occur if the elevator is departed.
