PROBLEM TO BE SOLVED: To provide a door-opened travel preventing device which eliminates the need of a control circuit and components provided on a guide rail, and which can prevent an elevator car from travelling with the door opened.SOLUTION: A door-opened travel preventing device 20 which is provided in an elevator including a guide rail 2 installed upright in a hoistway 1, a car frame 3 slidably supported by the guide rail 2 and traveling in the vertical direction, and an elevator car 5 supported by the car frame 3, and which prevents the elevator car 5 from travelling in the state in which a door 6 of the elevator car 5 is opened, is provided on the elevator car 5 side near the moving end of the door 6 of the elevator car 5 during the door opening operation, and moves rotationally with the movement of the door 6 of the elevator car 5 in the moving end direction during the door opening operation. The door-opened travel preventing device is equipped with a rotating body 21 which is pressed to be engaged to a predetermined part, for example, each end part of a door 8 of an elevator hall 7 or each pocket 11 in which the door 8 of the elevator hall 7 is held.SELECTED DRAWING: Figure 3
【課題】制御回路を要することなく、またガイドレールに設けられる部品を要することなく乗かごの戸開走行を防止することができる戸開走行防止装置の提供。【解決手段】本発明は、昇降路1内に立設されたガイドレール2と、このガイドレール2に摺動可能に支持され上下方向に走行するかご枠3と、このかご枠3に支持され乗かご5とを有するエレベータに設けられ、乗かご5の戸6が開いた状態で乗かご5が走行することを防止する戸開走行防止装置20であって、乗かご5の戸6の開動作時の移動端付近の乗かご5側に設けられ、乗かご5の戸6の開動作時の移動端方向への移動に伴って回動し、所定部位、例えば乗場7の戸8の端部、あるいは乗場7の戸8が保持されるポケット11のそれぞれに圧接される回動体21を備えた構成にしてある。【選択図】図3
