車体がかご敷居2よりはみ出しくA寸法)て、停止する
場合がある。(Problem to be Solved by the Invention) By the way, the draft of the car 13 that entered the elevator car was detected by the light emitter/receiver 6.7 of the photoelectric device because the car 14, which was not scheduled to be used at the time of elevator installation, entered the car. Zuni,
The car body may protrude beyond the car sill 2 (dimension A) and stop.
このとき前記はみ出し量(A)が乗場戸10に干渉しな
い大きさであると、乗場戸10は閉動作が可能であるた
め、乗場戸10は閉ぢて、エレベータが昇降することな
る。At this time, if the amount of protrusion (A) is large enough not to interfere with the landing door 10, the landing door 10 can be closed, so the landing door 10 is closed and the elevator moves up and down.
このような状態でエレベータが昇降すると、自動車々体
のはみ出し部分Aが乗場側の敷居等の昇降路構造物に衝
突する事故が発生する。When the elevator moves up and down in such a state, an accident occurs in which the protruding portion A of the vehicle body collides with a hoistway structure such as a sill on the landing side.
本発明は上記に鑑み、かご戸のない自動車用エレベータ
において、乗り湯側にはみ出した車体の部分を検出して
エレベータの運転を停止させる安全装置の提供を目的と
する。In view of the above, it is an object of the present invention to provide a safety device for an automobile elevator without a car door, which detects a portion of the car body protruding toward the passenger side and stops the operation of the elevator.
(課題を解決するための手段)
このため乗場戸のかごに対向する面の下端に、水平方向
に検知する測距式光電センサを取付け、乗場戸の閉動作
時においてのみ検知出力を作動するように構成する。(Means for solving the problem) For this reason, a distance-measuring photoelectric sensor that detects in the horizontal direction is installed at the lower end of the surface of the landing door facing the car, and the detection output is activated only when the landing door is closed. Configure.
(作用)
車体の長い自動車がかごに乗入れ、車体が乗場戸には接
触しないが、かご床敷居より出入口側にはみ出した場合
、乗場戸に装着した測距式光電センサが乗場戸の閉動作
に伴い降下しながら所定範囲内に異物(車体後部)が在
るか否かを検出し、異物を検出したときは、乗場戸の閉
動作を停止し反転させ、エレベータの運転を停止する。(Function) When a car with a long body enters the car and the car body does not touch the landing door but protrudes beyond the car floor sill to the entrance/exit side, the distance-measuring photoelectric sensor attached to the landing door will control the closing operation of the landing door. While descending, it detects whether there is a foreign object (rear part of the vehicle body) within a predetermined range, and when a foreign object is detected, the closing operation of the landing door is stopped and reversed, and the elevator operation is stopped.
(実施例)
第1図乃至第3図に示す実施例に基づいて本発明を説明
