To provide a pull-in detection device of an elevator door capable of effectively detecting the pull-in of the elevator door without installing sensors on an entire detection surface and also being easily installed.SOLUTION: A pull-in detection device of an elevator door has a long rail 31 attached to the pull-in end part of the elevator door, a switch 33 arranged on a base plate supported by the rail 31 at a predetermined interval, and a long rotating lever 36 of which one end part is rotatably supported by the rail 31, which has a free end arranged so as to project to the side facing the elevator door, is provided at the position corresponding to the switch 33, and has the pressing part to press the switch 33 by a rotation. The rotating lever 36 is configured so as to rotate around its one end part when its free end part side is pushed by foreign objects and so that the pressing part presses the switch.SELECTED DRAWING: Figure 3
【課題】検出面全面にセンサを設けなくとも効果的に検出を行うことができ、またその設置も容易なエレベータドアの引き込み検出装置を提供する。【解決手段】エレベータドアの引き込み端部に取り付けられた長尺のレール31と、レール31に保持された基板上に所定の間隔をおいて配置されたスイッチ33、レール31に一端部を回動自在に保持され、エレベータドアに面する側に突出して配置された自由端を有し、スイッチ33に対応する位置に設けられ、回動によりスイッチ33を押圧する押圧部を有する長尺状の回動レバー36とを有し、回動レバー36は、その自由端部側が異物により押されることで一端部を中心に回動し、押圧部がスイッチを押すように構成されている。【選択図】図3
