Abstract
Description
このドアの開閉装置においては、車両本体に対して固定されたベース板の略中央に、戸閉めスイッチが取り付けられている。そして、両側のドアが完全に閉じたときに、一方のドアの吊り金具に設けたスイッチ作動金具が、戸閉めスイッチに当接することで、両開きのドアが閉じたことが検知される。そして、戸閉めスイッチからの信号によってソレノイドなどが励磁され、ロック棒がロック装置に係止してドアをロックする。
しかしながら、両開きのドアを連動させる機構が故障する可能性はゼロではなく、ドアを連動させる機構が故障した場合においても、確実に両開きのドアが全閉位置にあるか否かを検知することができる鉄道車両用ドアスイッチが求められている。
そこで、上記のような戸閉めスイッチを、両開きの各ドアに対応させて2つ設けることも考えられるが、この方法によると、スイッチの数が増加し、電気部品が増えることにより、システム全体の故障率が上がるおそれがある。また、部品点数増加によりコストも上昇してしまう。また、戸閉めスイッチを車体に固定する代わりに一方のドアに設け、他方のドアで戸閉めスイッチを作動させることも考えられるが、ドアの開閉に伴って戸閉めスイッチの配線も開閉ストロークと同程度に大きく動くため、配線が断線しやすくなり、確実に両開きのドアが全閉位置にあるか否かを検知することが困難である。更に配線の耐久性が要求されるため、コストも上昇してしまう。
これにより、スイッチの数を増やすことなく、より確実に両開きのドアが全閉位置にあるか否かを検知することができる。
これにより、ドアが全閉位置に到達していないときに、誤って、ドアがロックされてしまうことを防ぐことができる。また、ドアが全閉位置に到達していないときに、誤って、ドア開閉のための駆動出力が制御されてしまうことを防ぐことができる。
図1は、本発明の実施形態に係るドア開閉装置1を示す全体図である。
ドア開閉装置1は、ベース板2を介して、鉄道車両の本体の側壁に固定されている。当該ドア開閉装置1は、ラックアンドピニオン機構を用いて、両開きの一対のドア(ドア100a,ドア100b)を開閉する装置である。当該ドア100a,100bは、全閉状態で、鉄道車両の本体の側壁に形成された乗降口を全て覆うように構成された平板状のドアである。また、ラックアンドピニオン機構は、車両の前後方向に延びる一対のラック3a,3bと、当該一対のラック3a,3bにそれぞれ噛み合うピニオン(図示せず)とを備えて構成される。
レール部材6a,6bは、車両本体に固定されたガイドレール8a,8bによりラック側ブラケット5a,5bの移動方向と平行に案内される。また、ドア吊り用ブラケット7a,7bは、それぞれ、ドア100a及びドア100bの上端部の2箇所に固定されている。
当該ドアスイッチ10は、車両前後方向における、乗降口の中央部の上方(遊星歯車機構4の下方)に、ベース板9を介して配置されている。即ち、ドアスイッチ10は、全閉位置にあるドア100a,100bの戸先の上方に位置するように配置されている。
図2は、図1に示すドア開閉装置1に設けられたドアスイッチ10近傍部の拡大図である。また、図3は、図2に示すドアスイッチ10をドア100a,100bの開閉方向と平行に車両前方側(ブッシュ35側)から見た図である。また、図4(a)は、ドアスイッチ10をベース板9とは逆側から見た図である。尚、図4(a)において、リミットスイッチ20の内部の構造が分かるように、リミットスイッチ20の本体ケース21の一部を省略して示している。また、図4(b)は、図4(a)に示すドアスイッチ10を矢印A方向から見た図である。
図3及び図4に示すように、レール40は、ドア100a,100bの開閉方向と平行に延びるようにベース板9に対して固定されている。そして、スイッチケース30の底板31には、レール40と係合するガイド部材32が固定されている。当該ガイド部材32は、当該スライドレール40に係合した状態で、当該スライドレール40に沿って移動可能である。これにより、スイッチケース30は、レール40に沿って、ドア100a,100bの開閉方向と平行に移動可能である。また、本実施例においては、リミットスイッチ20のメンテナンスが行いやすいように、スイッチケース30の底板31の反対側は開放されている。
これにより、ロッド22の先端が軸方向に付勢され、当該ロッド22がバネ23の付勢力に抗して軸方向基端側に所定量移動すると、当該一対の板部24が、一対の電極25に当接し、検知信号がドア開閉装置1の制御部に出力される。
図6は、ドアスイッチ10の作動を説明するための模式図である。
尚、上記実施形態の構成と、図6に模式的に示した構成との対応関係は以下の通りである。
図2に示す付勢軸52a,52b及び付勢板53a,53bは、図6における、付勢部55a,55bに相当する。また、図4に示すロッド22及び一対の板部24は、図6におけるロッド26a及び被検知部26bを有するロッドユニット26に相当する。また、図4に示すバネ23が、図6におけるバネ27に相当する。また、図4に示すスイッチケース30が、図6に示すスイッチケース36に相当する。また、図4における一対の電極25は、図6における検知部28に相当する。
図6(b)は、2つのドアが、正常に閉動作を行い、いずれも全閉位置まで到達したときの状態を示している。
図6(c)は、ドア開閉装置1の故障により、両開きの2つのドアの一方のドア100aのみが、全閉位置まで到達した状態を示している。
図6(d)は、ドア開閉装置1の故障により、両開きの2つのドアの他方のドア100bのみが、全閉位置まで到達した状態を示している。
図6(a)に示す状態から、更にドア100a,100bが閉方向に移動すると、当該ドア100a,100bに対して固定された2つの付勢部55a,55bは、互いに近づく方向(図6における矢印X2方向)に移動し、当該付勢部55a,55bが、ほぼ同時に、ロッド26aの先端及びスイッチケース36に当接する(図6(a)において二点差線で示す)。
更に、ドア100a,100bが閉方向に移動することにより、ロッドユニット26は付勢部55aからの付勢力により、バネ27の付勢力に抗して、当該付勢部55aの移動方向と同じ方向に移動する(図6(b)参照)。
一方、スイッチケース36は、付勢部55bからの付勢力により、バネ27の付勢力に抗して、当該付勢部55bの移動方向と同じ方向にスライドレール40(図6において省略)上を移動する。
即ち、ドア100a,100bが閉方向に移動することで、バネ27が縮まるように変形し、被検知部26bと、検知部28との間隔が狭くなるように、当該ロッドユニット26とスイッチケース36との相対位置関係が変化する。
このように、ロッドユニット26のみが直接付勢されることにより、スイッチケース36がスライドレール40に沿って、付勢部55aの移動方向と同じ方向に移動する。このとき、バネ27の縮みはほとんどなく、被検知部26bと検知部28との間隔は、図6(a)に示す状態における間隔に比べて、ほとんど変化しない。
これにより、ドア100bが完全に閉じていない場合は、ドアスイッチ10から検知信号が出力されることはない。
このように、スイッチケース36のみが直接付勢されることにより、スイッチケース36とロッドユニット26とがスライドレール40に沿って、付勢部55bの移動方向と同じ方向に移動する。このとき、バネ27の縮みはほとんどなく、被検知部26bと検知部28との間隔は、図6(a)に示す状態における間隔に比べて、ほとんど変化しない。
これにより、ドア100aが完全に閉じていない場合は、ドアスイッチ10から検知信号が出力されることはない。
(1)
以上説明したように、本実施形態に係るドア開閉装置1は、ドアスイッチ10を備えている。
このドアスイッチ10は、両開きのドア100a,100bを備える鉄道車両に設置される鉄道車両用のドアスイッチであって、ベース板9(車両本体)に対して相対移動可能に設けられ、一方のドア100aが全閉位置に向かって移動するときに付勢されるロッド22(第1受動部)と、ベース板9及びロッド22に対して相対移動可能に設けられ、他方のドア100bが全閉位置に向かって移動するときに付勢されるスイッチケース30(第2受動部)と、ロッド22とスイッチケース30との相対位置が所定の相対位置となり、ロッド22に固定された一対の板部24が、スイッチケース30に固定された一対の電極25に当接したときに、検知信号を出力する電気回路(検知手段)と、ロッド22とスイッチケース30との相対位置が、前記所定の相対位置(板部24と電極25とが当接するときの相対位置)とならないように、ロッド22及びスイッチケース30を付勢するバネ23(付勢手段)と、を備える。ここで、前記所定の相対位置は、ロッド22とスイッチケース30とが、バネ23による付勢力に抗して両開きの2つのドア100a,100bに設けられた付勢板53a,53bで付勢されながら、当該2つのドア100a,100bがいずれも全閉位置まで移動したときの、ロッド22とスイッチケース30との相対位置である。
これにより、スイッチの数を増やすことなく、より確実に両開きのドア100a,100bがいずれも全閉位置にあるか否かを検知することができる。
ドアスイッチ10において、ロッド22及びスイッチケース30は、ベース板9に対して、ドア100a,100bの開閉方向と平行に移動できるように設けられている。
これにより、ドア駆動機構(電動モータ、遊星歯車機構4、ラックアンドピニオン機構等)の下方の空間であって、ドア100a,100bが全閉位置にあるときにドア100aの戸先側に固定されたドア吊り用ブラケット7aと、ドア100bの戸先側に固定されたドア吊り用ブラケット7bとの間に位置する横長の空間を利用して、ドアスイッチ10を配置することができる。
ドアスイッチ10は、リミットスイッチ20を備えている。
リミットスイッチ20は、ロッド22と、ロッド22を進退自在に保持するスイッチケース30と、ロッド22とスイッチケース30との間に配置されたバネ23(弾性部材)と、ロッド22がバネ23の弾性力に抗してスイッチケース30に対して所定量移動し、ロッド22に設けられた一対の板部24が一対の電極25に当接したときに、検知信号を出力する電気回路(検知手段)と、を有する。
当該リミットスイッチ20は、ベース板9に対して、ロッド22のスイッチケース30に対する進退方向と平行に移動可能に設けられている。そして、一方のドア100aに設けられた付勢板53aにロッド22が付勢され、かつ、他方のドア100bに設けられた付勢板53bにスイッチケース30が付勢されることで、ロッド22が、スイッチケース30に対して、バネ23の弾性力に抗して移動し、2つのドア100a,100bがいずれも全閉位置に到達したときに、ロッド22がスイッチケース30に対して前記所定量だけ移動して、一対の板部24が一対の電極25に当接するように構成されている。
以上説明したドアスイッチ10を備えるドア開閉装置1は、ドアスイッチ10から出力された検知信号を受信する制御部を備える。当該制御部は、ドアスイッチ10から出力された検知信号を受信すると、ロック装置を駆動して、ドア100a,100bを全閉位置でロックする。
これにより、ドア100a,100bが全閉位置に到達していないときに、誤って、ロック装置を駆動してしまうことを防ぐことができる。
これにより、閉動作中のドア100a,100bに挟まった薄いものをセンサの精度を上げることなく検知可能になる。即ち、閉動作中のドア100a,100b間に、異物が挟まってドア100a,100bが完全に閉まっていないときに、誤って、ドア100a,100bが閉じたことを検知する検知信号が出力されてしまうことを防止することができる。
上記実施形態は以下のように変形して実施することができる。
図7は、上記実施形態の第1変形例の作動を説明するための模式図である。第1変形例に係るドア開閉装置は、ドアスイッチの構成が異なる点で、上記実施形態と異なっている。そのため、ドアスイッチの構成のみ説明し、その他の構成については省略する。尚、上記実施形態と同一部材には同一符号を付して説明する。
ロッド62とスイッチケース61との間には、バネ64が配置されている。当該バネ64は、ロッド62を基端側から先端側に付勢している。
また、ロッド62には、軸方向の中間部において磁石66が固定されている。当該磁石66は、ロッド63側に対向するように、ロッド62に固定されている。
そして、ドア100aの閉動作に伴って、付勢部56aが閉方向に移動することにより、当該付勢部56aでロッド62の先端が付勢されるように構成されている。
また、ロッド63は、ベース板9に直交する方向(図7における紙面奥行き方向)において、ロッド62と略同位置に配置されている。即ち、鉛直方向と平行に見て、ロッド62の中心軸と、ロッド63の中心軸とが同一直線状に位置するようにロッド62,63が配置されている。
ロッド63とスイッチケース61との間には、バネ65が配置されている。当該バネ65は、ロッド63を基端側から先端側に付勢している。
また、ロッド63には、軸方向の中間部において磁気センサ67が固定されている。当該磁気センサ67は、ロッド62側に対向するように、ロッド63に固定されている。
そして、ドア100bの閉動作に伴って、付勢部56bが閉方向に移動することにより、当該付勢部56bでロッド63の先端が付勢されるように構成されている。
ここで、磁気センサ67は、所定の範囲(以下、磁気センサ67の検知範囲という)内に磁石66が近づいたときに磁石の磁気を検知し、ドア開閉装置の制御部に対し検知信号を出力するものである。そして、本変形例においては、磁石66が磁気センサ67に対向したとき(即ち、磁石66が磁気センサ67に最も近づいたとき)にのみ、磁石66が磁気センサ67の検知範囲内に入るように、ロッド62,63の間隔が調整されている。
そのため、2つのドア100a,100bが、いずれも全閉位置まで到達したときにのみ、磁気センサ67が検知信号を出力することになる。
同様に、図6(d)に示すように、ドア開閉装置1の故障により、ドア100bのみが、全閉位置まで到達し、ドア100aが途中で停止した状態でも、磁気センサ67と磁石66とが互いに対向せず、磁気センサ67から検知信号は出力されない。
以上説明したように、第1変形例に係るドアスイッチ11は、ベース板9(車両本体)に対して相対移動可能に設けられ、一方のドア100aが全閉位置に向かって移動するときに付勢されるロッド62(第1受動部)と、ベース板9及びロッド62に対して相対移動可能に設けられ、他方のドア100bが全閉位置に向かって移動するときに付勢されるロッド63(第2受動部)と、ロッド62とロッド63との相対位置が所定の相対位置となり、磁石66が検知範囲内に近づいたときに、検知信号を出力する磁気センサ67(検知手段)と、ロッド62とロッド63との相対位置が、所定の相対位置(磁石66が磁気センサ67の検知範囲内に入る相対位置)とならないように、ロッド62及びロッド63を付勢するバネ64,65(付勢手段)と、を備える。ここで、前記所定の相対位置は、ロッド62とロッド63とが、バネ64,65による付勢力に抗して両開きの2つのドア100a,100bに設けられた付勢部56a,56bで付勢されながら、当該2つのドア100a,100bがいずれも全閉位置まで移動したときの、ロッド62とロッド63との相対位置である。
これにより、スイッチの数を増やすことなく、より確実に両開きのドア100a,100bがいずれも全閉位置にあるか否かを検知することができる。
上記実施形態は以下のように変形して実施することができる。
図8及び図9は、上記実施形態の第2変形例の作動を説明するための模式図である。第2変形例に係るドア開閉装置は、ドアスイッチの構成が異なる点で、上記実施形態と異なっている。そのため、ドアスイッチの構成のみ説明し、その他の構成については省略する。尚、上記実施形態と同一部材には同一符号を付して説明する。
尚、ドア100a,100bには、それぞれ、支持部材51a,51bを介して、ドアの開閉方向と平行に延びる棒状の付勢部57a,57bが固定される。
この状態では、軸71回りの方向において、磁気センサ75と磁石76とは、互いに離れている。
また、第2回動部材73は、付勢部57bに付勢されて、バネ74の付勢力に抗して、第2ストッパ78から離れる方向(図8において矢印R1方向)に軸71回りに回動する。
即ち、付勢部57a,57bが閉方向に移動することにより、磁気センサ75と磁石76とが互いに近づく方向に移動する。
ここで、磁気センサ75は、所定の範囲(以下、磁気センサ75の検知範囲という)内に磁石76が近づいたときに磁石の磁気を検知し、ドア開閉装置の制御部に対し検知信号を出力するものである。そして、本変形例においては、磁石76が磁気センサ75に重なったとき(即ち、磁石76が磁気センサ75に最も近づいたとき)にのみ、磁石76が磁気センサ75の検知範囲内に入るように、第1回動部材72と第2回動部材73との間隔(軸71と平行な方向における間隔)が調整されている。
そのため、2つのドア100a,100bが、いずれも全閉位置まで到達したときにのみ、磁気センサ75が検知信号を出力することになる。
同様に、図9(b)に示すように、ドア開閉装置1の故障により、ドア100bのみが、全閉位置まで到達し、ドア100aが途中で停止した状態でも、磁気センサ75と磁石76とが重ならず、磁気センサ75から検知信号は出力されない。
(1)
以上説明したように、第2変形例に係るドアスイッチ12は、ベース板9(車両本体)に対して相対回動可能に設けられ、一方のドア100aが全閉位置に向かって移動するときに付勢される第1回動部材72(第1受動部)と、ベース板9及び第1回動部材72に対して相対回動可能に設けられ、他方のドア100bが全閉位置に向かって移動するときに付勢される第2回動部材73(第2受動部)と、第1回動部材72と第2回動部材73との相対位置が所定の相対位置となり、磁石76が検知範囲内に近づいたときに、検知信号を出力する磁気センサ75(検知手段)と、第1回動部材72と第2回動部材73との相対位置が、所定の相対位置(磁石76が磁気センサ75の検知範囲内に入る相対位置)とならないように、第1回動部材72及び第2回動部材73を付勢するバネ74(付勢手段)と、を備える。ここで、前記所定の相対位置は、第1回動部材72と第2回動部材73とが、バネ74による付勢力に抗して両開きの2つのドア100a,100bに設けられた付勢部57a,57bで付勢されながら、当該2つのドア100a,100bがいずれも全閉位置まで移動したときの、第1回動部材72と第2回動部材73との相対位置である。
これにより、スイッチの数を増やすことなく、より確実に両開きのドア100a,100bがいずれも全閉位置にあるか否かを検知することができる。
ドアスイッチ12において、第1回動部材72及び第2回動部材73は、ベース板9に対して固定された軸71(回動軸)回りに回動自在に設けられており、軸71は、平板状のドア100a,100bに対して垂直な方向(車両の幅方向)に延びている。
ドアスイッチ12において、第1回動部材72に設けられた磁気センサ75(第1検知部)と、第2回動部材73に設けられた磁石76(第2検知部)とが、所定の位置関係になったとき、即ち、磁気センサ75の検知範囲内に磁石76が入ったときに、当該磁気センサ75は、検知信号を出力する。この磁気センサ75は、第1回動部材72において付勢部57aに付勢される位置よりも、軸71から離れた位置に配置されている。また、磁石76は、第2回動部材73において付勢部57aに付勢される位置よりも、軸71から離れた位置に配置されている。
第2変形例のように、第1回動部材72と第2回動部材73との間にバネ74を設置する場合に限らず、図10に示すように構成してもよい。
そして、2つのドアが、いずれも全閉位置まで到達すると、図10(b)に示すように、磁気センサ75と磁石76とが重なる。
第3変形例のように、第1回動部材72が、扇状に形成されている場合に限らず、例えば、図11において、第1回動部材72'として示すように、L字形状またはV字形状に形成することも可能である。この場合、第1回動部材72'を軽量化できるとともに、当該第1回動部材72'が回動するために必要なスペースを小さくすることができる。
