Description

【0001】
【発明の属する技術分野】
この発明は、かご内に積載された車両の行き過ぎを規制して車両と出入口の戸との衝突を未然に防止するエレベータの車止め装置に係るものである。
【0002】
【従来の技術】
図13は、実開昭56−13477号公報に開示されたものと同様の機構を有する従来のエレベータの車止め装置を示す。
即ち、正面側乗場1Fには乗場出入口2Fと乗場戸3Fが設けられ、背面側乗場1Rには乗場出入口2Rと乗場戸3Rが設けられている。かご4には正面側Fにかご出入口6Fとかご戸7Fが設けられ、背面側Rにかご出入口6Rとかご戸7Rが設けられている。
【0003】
また、正面側Fのかご床5には車止め具61Fと、この車止め具61Fを上下動させるリンク機構63Fと、このリンク機構63Fを作動させる足踏棒62Fが設けられている。背面側Rのかご床5には、同様に車止め具61Rとリンク機構63Rと足踏棒62Rが設けられている。両リンク機構63Fと63Rは、連結棒64で連結されており、足踏棒62Fを踏み込むことにより車止め具61Fを上昇させ、車止め具61Rを下降させる。足踏棒62Rを踏み込むことにより車止め具61Rを上昇させ、車止め具61Fを下降させる。
【0004】
正面側乗場1Fから台車11がかご4に乗り入れる場合、作業者12は正面側Fの車止め具61Fを下げなければならない。そこで、背面側Rの足踏棒62Rを踏み込み、リンク機構63Rを時計方向へ揺動させて車止め具61Rを上昇させる。リンク機構63Fは連結棒64を介して反時計方向へ揺動して車止め具61Fを下降させる。
【0005】
かご4に乗り込むと、台車11の前車輪11aからの張出寸法Hoは、車止め具61Rの台車11側の面からかご戸7Rの内面迄の寸法Soよりも小さいので、仮に台車11を背面側Rへ突進させたとしても、台車11は車止め具61Rに当って停止し、かご戸7Rに当ることはない。
目的階に到着したならば、正面側Fの足踏棒62Fを踏み込んで車止め具61Rを下降させた後、台車11をかご4から降車させる。
【0006】
【発明が解決しようとする課題】
従来のエレベータの車止め装置は、上記のとおり、車止め具61Rからかご戸7R迄の寸法Soが固定されていて変更することはできなかった。このため、使用される台車11は寸法Soが小さいものでなければならず、台車11の選択の範囲が狭い、という問題があった。
また、使用台車11の選択範囲を広げるために、車止め具61Rをかご4の内側寄りに設置してかご戸7R迄の寸法Soを予め大きくしておくことも考えられるが、かご床5の有効面積を不必要に狭めることになる、という問題もあった。
正面側Fについても同様の問題があった。
【0007】
この発明は、上記問題点を解決するためになされたものであり、かご内に積載される車両の車輪からの前後方向の張出寸法に見合った適所で車止め具を作動させることにより、かご床の有効面積を不必要に狭めることなく、使用車両の上記張出寸法の変化に対応することができるエレベータの車止め装置を提供することを目的とする。
【0008】
【課題を解決するための手段】
この発明に係るエレベータの車止め装置は、かご床のかご出入口反対側の縁近傍に上下動可能に設けられ、かご出入口でかご戸が開いているときに、上昇している車止め具を備え、車止め具は、長手をかご床のかご出入口反対側の縁に平行する方向へ向けてかご床のかご出入口反対側の縁側からかご出入口側へ複数列設され、かご床のかご出入口反対側の縁に最も近い位置に設置された駆動車止め具が上下に駆動され、車両の車輪からの前方向の張出寸法よりもかご床のかご出入口反対側の縁からかご出入口側に設置された車止め具の内でかご床のかご出入口反対側の縁に最も近い位置に取り付けられた適所車止め具が、駆動車止め具に着脱可能な連結具を介して連結されて連動して上下に駆動されるものである。
また、この発明に係るエレベータの車止め装置は、かご床のかご出入口反対側の縁近傍に上下動可能に設けられ、かご出入口でかご戸が開いているときに、上昇している車止め具を備え、車止め具は、長手をかご床のかご出入口反対側の縁に平行する方向へ向けてかご床のかご出入口反対側の縁側からかご出入口側へ複数列設され、車両の車輪からの前方向の張出寸法よりもかご床のかご出入口反対側の縁からかご出入口側に設置された車止め具の内でかご床のかご出入口反対側の縁に最も近い位置に取り付けられた適所車止め具のみが上下に駆動されるものである。
【0009】
【発明の実施の形態】
実施の形態1.
図1から図8は、この発明に係るエレベータの車止め装置の実施の形態1を示し、特に、二方口のエレベータの車止め装置を示す。図中の符号で、末尾の「F」又は「R」は正面側又は背面側を示す。以下、必要に応じて両者を区別することなく説明する。
【0010】
図1は、エレベータの奥行方向の縦断面図で、特に、正面側Fから車両が乗り入れるときの状態を示す。図中、1は乗場、2は乗場出入口、3は乗場戸、4はかご、5はかご床、6はかご出入口、7はかご戸、8はかご戸7が開き始めると開放され、閉じると閉成する戸閉検出スイッチ、11はかご4に乗降する台車からなる車両、12は台車11を使用する作業者、20は長手をかご戸7に平行する方向へ向けてかご床5の出入口近傍に設けられたエレベータの車止め装置であって、台車11が乗り入れる正面側Fの車止め装置20Fは、その車止め具21Fが下降して台車11の通行を可能とし、背面側Rの車止め装置20Rの車止め具21Rは上昇して台車11の行き過ぎを規制している。
【0011】
図2は、台車11がかご4に乗り終った状態を示すエレベータの奥行方向の縦断面図、図3は、同じく奥行方向の横断面図である。図1と同符号は同一部分を示し、説明を省略する。乗場戸3及びかご戸7はいずれも閉じている。車止め装置20の車止め具21は正面側F及び背面側R共に上昇しており、仮に、台車11が図2に符号11′で示したとおり、かご4内で背面側Rへ移動したとしても車止め具21Rによって止められるので、かご戸7Rに衝突することはない。台車11が正面側Fへ移動したときも同様である。
【0012】
図4は、背面側Rから台車11が乗り出すときの状態を示すエレベータの奥行方向の縦断面図で、図1と同符号は同一部分を示し、説明を省略する。
台車11が乗り出す背面側Rの車止め装置20Rは、その車止め具21Rが下降して台車11の通行を可能とし、正面側Fの車止め装置20Fの車止め具21Fは上昇して台車11の行き過ぎを規制している。
【0013】
図5において、21R1は、複数の背面側Rの車止め具21Rの内、かご戸7Rに最も近い位置に設置された戸側車止め具21R1の詳細を示す斜視図である。ここで、「R1」は背面側Rのかご戸7R側から最初の車止め具21Rであることを意味する。台車11の車輪11aが当る頭部21aR1は、図3に示したとおり、かご出入口6Rの全幅よりも長い板材からなる。頭部21aR1の下面中央部と両端部には、頭部21aR1よりも薄い板材からなる腹部21bR1が長手方向へ沿って所定の幅で下方へ向けて凸設されている。腹部21bR1の下端には、腹部21bR1と同幅で腹部21bR1よりも厚い脚部21cR1が固着されている。更に、中央部の脚部21cR1には一対のアイプレート24R1が取り付けられている。
【0014】
図6は、図2に示す背面側Rの車止め装置20Rを拡大して示す詳細図であり、図7は、図6に示すVII−VII線部分のかご4全高の断面を矢視した断面図である。図中、図1と同符号は同一部分を示す。
5hRは、長手をかご戸7Rに平行する方向へ向けてかご床5の出入口近傍に欠切された床穴で、3列の車止め具21R1〜21R3が遊挿されてかご戸7R側から奥側へ向けて列設されている。22Rは、床穴5hRが形成された部位のかご床5の下面に取り付けられたハット形の車止めガイドで、この車止めガイド22Rの溝部には貫通孔が形成されており、その貫通孔に各車止め具21R1〜21R3の腹部21bR1〜21bR3が遊嵌されている。
【0015】
従って、車止め具21R1〜21R3は、車止めガイド22Rに案内されて上下動し、上昇したときは脚部21cR1〜21cR3の張出部分が下側から車止めガイド22Rに当接し、下降したときは頭部21aR1〜21aR3の張出部分が上側から車止めガイド22Rに当接する。このとき頭部21aR1〜21aR3の上面は、かご床5と同一面となる。
【0016】
23R1は、車止め具21R1の脚部21cR1底面と車止め具21R2の脚部21cR2底面の間に跨設された連結板、23R2は、車止め具21R2の脚部21cR2底面と車止め具21R3の脚部21cR3底面の間に跨設された連結板である。従って、連結板23R1及び23R2によって上下動する車止め具21R1〜21R3の数を選択して、台車11を停止させる位置を変えることができる。図6の例では、車止め具21R1〜21R3は連結板23R1及び23R2によって連結されており、一体となって上下動する。従って、台車11はかご戸7Rから最遠の位置で停止することになる。24R1は、車止め具21R1の脚部21cR1底面に下方へ突設されたアイプレートである。
【0017】
25Rは、かご床5の底面から垂設されたブラケット26Rに取り付けられた電動機で、車止め具21R1〜21R3を上下に駆動する駆動手段である。27Rは、電動機25Rの回転軸に取り付けられたウォーム、28はブラケット26Rから水平方向へ相対峙して併設されたブラケット29Rに回動自在に軸支されてウォーム27Rと噛合して回動するウォームギヤである。30R1はウォームギヤ28Rとアイプレート24R1に軸支されたアームで、ウォームギヤ28Rの揺動によって戸側車止め具21R1を上下動させるものである。
【0018】
31Rは戸側車止め具21R1に取り付けられたカム、32Rはブラケット33Rを介してかご床5の下面に取り付けられた上限スイッチで、カム31Rとの係合により作動して電動機25Rによる戸側車止め具21R1の上昇を停止させるものである。34Rは下限スイッチで、カム31Rとの係合により作動して電動機25Rによる戸側車止め具21R1の下降を停止させるものである。
【0019】
次に、動作を説明すると、かご戸7Rが閉じていて、戸閉検出スイッチ8Rが作動しているときは、車止め具21R1〜21R3は上昇して停止している。このため、台車11の停止位置は、かご戸7Rから所定距離を隔てた範囲に制限される。
かご戸7Rが開き始めると、戸閉検出スイッチ8Rが復帰する。この復帰によって電動機25Rが回動してウォームギヤ28Rを図示のD方向へ揺動させ、アーム30R1を介して車止め具21R1を下降させる。車止め具21R2は連結板23R1を介して車止め具21R1に連動して下降し、車止め具21R3は連結板23R1及び23R2を介して車止め具21R1に連動して下降する。下限スイッチ34Rがカム31Rと係合して作動すると、電動機25Rは停止する。このとき、頭部21aR1〜21aR3の張出部分が車止めガイド22Rに当接して頭部21aR1〜21aR3の上面はかご床5と同一面となる。
【0020】
戸閉指令が出されると、電動機25Rは逆回動してウォームギヤ28Rを図示のU方向へ揺動させ、アーム30R1を介して車止め具21R1を上昇させる。車止め具21R2及び21R3も連結板23R1及び23R2を介して上昇する。上限スイッチ32Rがカム31Rに係合して作動すると、電動機25Rは停止する。このとき、脚部21cR1〜21cR3の張出部分が下側から車止めガイド22Rに当接する。上記動作は、図12に示した電気回路接続図によっても開示した。
【0021】
図8は、上下動させる車止め具21R、即ち、適所車止め具の設定を示した説明用図である。
かご床5を有効に利用するため、台車11は出来るだけかご戸7Rに近付けて停止させることが望ましい。そこで、車輪11aからの前後方向の張出寸法よりもかご戸7Rから奥側に設置された車止め具21Rの内で、かご戸7Rに最も近い位置に取り付けられた車止め具21R、即ち、適所車止め具を上下方向に駆動するようにしたものである。
【0022】
図8(a)は、かご戸7Rから最も離れた位置に設けられた車止め具21R3を適所車止め具とする場合を示す。
即ち、台車11の前車輪11aからの張出寸法はH3であり、張出寸法H3は車止め具21R3の台車11側の面からかご戸7Rの内面迄の寸法S3よりも小さいが、車止め具21R2の上記寸法S2よりも大きい場合は、車止め具21R3を適所車止め具に設定する。
具体的には、図6に示したように、連結板23R1及び23R2によって車止め具21R3を車止め具21R1と連動させる。この設定により、台車11とかご戸7Rとの衝突を阻止することができる。
【0023】
図8(b)は、車止め具21R2を適所車止め具とする場合を示す。
即ち、台車11の前車輪11aからの張出寸法はH2であり、張出寸法H2は車止め具21R2の台車11側の面からかご戸7Rの内面迄の寸法S2よりも小さいが、かご戸7Rに最も近い戸側車止め具21R1の上記寸法S1よりも大きい場合は、車止め具21R2を適所車止め具に設定する。
具体的には、連結板23R1によって車止め具21R2を戸側車止め具21R1と連動させる。この設定により、台車11とかご戸7Rとの衝突を阻止することができると共に、かご床5を有効利用できる。
【0024】
図8(c)は、戸側車止め具21R1を適所車止め具とする場合を示す。
即ち、台車11の前車輪11aからの張出寸法はH1であり、張出寸法H1は車止め具21R1の台車11側の面からかご戸7Rの内面迄の寸法S1よりも小さい場合は、車止め具21R1を適所車止め具に設定することができる。
具体的には、連結板23R1を取り外して戸側車止め具21R1のみを上下動させる。この設定により、台車11とかご戸7Rとの衝突を阻止することができると共に、かご床5の広い範囲を有効利用することもできる。
以上は、背面側の車止め装置20Rについて説明したが、正面側の車止め装置20Fについても同様であり、上記記載から容易に類推できるので、説明を省略する。
【0025】
上記実施の形態1のエレベータの車止め装置によれば、長手をかご戸7に平行する方向へ向けた車止め具21を、かご床5の出入口近傍にかご戸7側から奥側へ3列設け、この車止め具21の内、かご戸7に最も近い戸側車止め具21と、かご4に積載される台車11の車輪11aからの前後方向の張出寸法H1〜H3よりもかご戸7から奥側に設置された車止め具21であって、最もかご戸7側に位置する車止め具21である適所車止め具21とを、連結板23で連結し、かご戸7の開閉に合わせて上下動させるようにしたものである。
このため、台車11とかご戸7との衝突を阻止することができると共に、車止め装置20によってかご床5の有効面積が不必要に狭められることがない。
また、連結板の着脱によって適所車止め具21を戸側車止め具21と連結することができるので、車輪11aからの前後方向の張出寸法の変化に容易に対応することもできる。
【0026】
実施の形態2.
図9は、この発明に係るエレベータの車止め装置の実施の形態2を示し、特に、二方口のエレベータの背面側の車止め装置20Rを示す。
図中、図6と同符号は同一部分を示す。また、末尾の「F」又は「R」は正面側又は背面側を示し、以下、必要に応じて両者を区別することなく説明する。
各車止め具21Rの脚部21cR下面には、それぞれアイプレート24Rが突設されている。ここでは、台車11の張出寸法H3に対応して車止め具21R3が適所車止め具として設定され、この適所車止め具21R3のアイプレート24R3にアーム30Rの一端部が軸支されている。
【0027】
アーム30Rの他端部には、各車止め具21R1〜21R3との取付けに合わせて取付孔30Rhが複数形成されており、アーム30Rは、この取付孔30Rhを介してウォームギヤ28Rに軸支されている。ウォームギヤ28Rの軸にはカム35Rが螺着されて共に揺動するようになっている。また、ブラケット29Rに固着されたブラケット36Rには上限スイッチ32R及び下限スイッチ34Rが取り付けられていて、適所車止め具21R3の上限位置及び下限位置でそれぞれ作動するようになっている。
【0028】
図9では、車止め具21R3を適所車止め具とした場合であるが、車止め具21R2又は21R1が適所車止め具となる場合は、車止め具21R2又は21R1とウォームギヤ28Rとをアーム30Rで連結する。ここで、アーム30Rの各取付孔30Rhは、対応する車止め具21R2又は21R1が上限位置に達したときに上限スイッチ32Rが作動し、下限位置に達したときに下限スイッチ34Rが作動する位置に穿設されているので、適所車止め具を変更する場合は、アーム30Rの他端部の取付け位置を変更するだけでよい。
以上は、背面側の車止め装置20Rについて説明したが、正面側の車止め装置20Fについても同様であり、上記記載から容易に類推できるので、説明を省略する。
【0029】
上記実施の形態2によっても、台車11とかご戸7との衝突を阻止することができると共に、車輪11aからの前後方向の張出寸法の変化に合わせて適所車止め具21を設定し、この適所車止め具21とウォームギヤ28とをアーム30で連結して上下動させるようにしので、車輪11aからの前後方向の張出寸法の変化にも容易に対応することもできる。
特に、適所車止め具のみを上下動させるようにしたので、揚重負荷が軽量となり、電動機25の容量を軽減することができる。
【0030】
実施の形態3.
図10〜図12は、この発明に係るエレベータの車止め装置の実施の形態3を示し、特に、車止め具21の頭部21aにかかる荷重を検出するようにしたものである。
図10は、図6に示した背面側Rの車止め装置20Rの車止め具21R1〜21R3に、それぞれ荷重検出手段40を装着した要部を示し、図中、図6と同符号は同一部分を示す。
図11は、奥行方向のかご4の横断面図で、図3と同符号は同一部分を示す。
【0031】
図10及び図11において、車止め具21R1の頭部21aR1上面には、荷重検出手段40R1が装着されている。この荷重検出手段40R1は、四方位に配設された4個を一群とする押ばね41R1と、この押ばね41R1の内径内に収納されて立設され、過圧縮を阻止するストッパ42Rと、各押ばね41R1の中間部位で頭部21aR1の上面に取り付けられて荷重を検出するリミットスイッチ43R1とで構成された荷重検出ユニットが、頭部21aR1の左右上面にそれぞれ一対設けられ、この荷重検出ユニットを、頭部21aR1の張出部に係止されて上下に移動可能なカバー44R1で覆ったものである。
従って、カバー44R1に重量がかかると押ばね41R1が圧縮されて沈む。所定値以上の重量がかかると、リミットスイッチ43R1が作動する。
車止め具21R2及び21R3の頭部21aR2及び21aR3の上面にも同構成の荷重検出手段40R2及び40R3が装着されている。
【0032】
図12に基いて動作を説明する。
43R1a〜43R3aは、それぞれリミットスイッチ43R1〜43R3のブレーク接点である。52R1〜52R3は、それぞれリミットスイッチ43R1〜43R3を無効にする無効手段である無効スイッチで、例えば、車止め具21R2が適所車止め具に設定されたために車止め具21R3が上下動しない場合、無効スイッチ52R3が閉成されてリミットスイッチ43R3は無効となる。51Rは荷重検出リレーで、51Raはメーク接点、51Rbはブレーク接点である。54Raは戸閉指令リレー(図示しない。)のメーク接点である。8Raは戸閉検出スイッチ8Rのメーク接点、8Rbは同じくブレーク接点である。32Raは上限スイッチ32Rのメーク接点、32Rb及び32Rcは同じくブレーク接点である。34Raは下限スイッチ34Rのメーク接点、34Rb及び34Rcは同じくブレーク接点である。
【0033】
53Rは上昇指令リレーで、そのメーク接点53Raの閉成によって電動機25Rを付勢して車止め具21R1を上昇させる。53Rbは、そのブレーク接点である。56Raは戸開指令リレー(図示しない。)のメーク接点である。55Rは下降指令リレーで、そのメーク接点55Raの閉成によって電動機25Rを付勢して車止め具21R1を下降させる。55Rbそのブレーク接点である。57Rは限時リレーで、57Rbは、その限時復帰のブレーク接点である。58はブザーからなる警報装置である。
【0034】
1.背面側Rのかご戸7Rが戸閉状態から開く場合
かご戸7Rが戸閉状態のときに、戸開指令が出されると、接点56Raが閉成されて下降指令リレー55Rが付勢される。この付勢によって接点55Raが閉成し、電動機25Rが付勢されて車止め具21Rが下降し始める。下限スイッチ34R作動すると接点34Rbが開放されて下降指令リレー55Rは消勢され、車止め具21Rは下限位置で停止し、台車11のかご4への乗降が可能となる。
【0035】
2.背面側Rのかご戸7Rが戸開状態から閉じる場合
戸開状態のときは、接点34Rbは開放され、接点32Rbは閉成されている。この状態で戸閉指令が出されると、接点54Raが閉成されて上昇指令リレー53Rが付勢される。この付勢によって接点53Raが閉成して電動機25Rが付勢され、車止め具21Rが上昇し始める。上限スイッチ32Rが作動すると接点32Rbが開放されて上昇指令リレー53Rは消勢され、電動機25Rは消勢されて車止め具21Rは上限位置で停止し、台車11の行過ぎを規制してかご戸7Rとの衝突を阻止する。
かご戸7Rが閉じ切ると戸閉検出スイッチ8Rの接点8Raが閉成するので、仮に車止め具21Rが上限位置から下降移動したとしても、この下降移動により上限スイッチ32Rが復帰して接点32Rbが閉成し、上昇指令リレー53Rは再度付勢されて車止め具21Rを上限位置へ復帰させる。従って、かご戸7Rが閉じている限り、車止め具21Rが下降することはない。
【0036】
【発明の効果】
この発明に係るエレベータの車止め装置は、以上述べたとおり、かご床のかご出入口反対側の縁近傍に上下動可能に設けられ、かご出入口でかご戸が開いているときに、上昇している車止め具を備え車止め具が、かご床のかご出入口反対側の縁からの寸法に対する調整機構を有したものである。
このため、かご内に積載される車両の車輪からの前後方向の張出寸法に見合った適所に設置された車止め具を選択して作動させることにより、かご床の有効面積を不必要に狭めることなく、かご戸と車両との衝突を回避することができる、という効果を奏する。
【0037】
4.車止め具21Rが所定時間以内に昇降動作を完了しなかった場合
車止め具21Rが下限位置と上限位置の間にあるときは、接点32Ra及び34Raはいずれも開放されている。この両者開放の時間が、限時リレー57Rの設定時間よりも長い場合、接点57Rbが閉成してブザー58が鳴動し、動作異常を報知する。
【0038】
上記実施の形態3によれば、車止め具21R毎に個別に荷重検出手段40Rを設け、車止め具21Rが上昇中に所定の重量以上の荷重がかかると荷重検出手段40Rが作動して警報を発するようにしたので、車止め具21Rの正常な動作に支障となる荷重を人為によって排除することができると共に、電動機25Rは車止め具21Rの駆動のみとなるから小容量で足りることになる。
また、荷重検出手段40Rを選択的に無効とする無効スイッチ52Rを備え、少なくとも適所車止め具21Rよりもかご4奥側に設置された車止め具21Rの荷重検出手段40Rを無効としたので、荷重検出手段40Rが不必要に作動するのを回避することができる。

2. When the car door 7R on the rear side R is closed from the open state
When the door is open, the contact 34Rb is opened and the contact 32Rb is closed. When a door closing command is issued in this state, the contact 54Ra is closed and the ascending command relay 53R is energized. By this energization, the contact 53Ra is closed, the electric motor 25R is energized, and the vehicle stopper 21R starts to rise. When the upper limit switch 32R is actuated, the contact 32Rb is opened, the ascending command relay 53R is de-energized, the motor 25R is de-energized, the car stopper 21R stops at the upper limit position, and the car door 7R is restricted by overtraveling the carriage 11. To prevent collisions.
When the car door 7R is completely closed, the contact 8Ra of the door close detection switch 8R is closed. Therefore, even if the car stopper 21R is moved downward from the upper limit position, the upper limit switch 32R is restored by this downward movement and the contact 32Rb is closed. Then, the ascending command relay 53R is energized again to return the vehicle stopper 21R to the upper limit position. Therefore, as long as the car door 7R is closed, the car stopper 21R does not descend.
