PROBLEM TO BE SOLVED: To provide a safety device for a passenger conveyor which can detect floating of an intersection part between a tread of a footstep and a riser.SOLUTION: A safety device for a passenger conveyor comprises: a sensor device which is arranged at one of skirt guards disposed outside of a moving footstep to generate a detection wave toward the other of skirt guards, does not detect the detection wave when the footstep does not exist in a direction of travel of the detection wave, and detects the detection wave reflected on the lateral face of an intersection part between a tread of the footstep and a riser when the footstep exists in the direction of travel of the detection wave; and a controller which detects floating of the intersection part between the tread of the footstep and the riser on the basis of a detection state of the detection wave by the sensor device.
【課題】踏段の踏板とライザーとの交わり部の浮き上がりを検出することができる乗客コンベアの安全装置を提供する。【解決手段】乗客コンベアの安全装置は、移動する踏段の外側に設けられたスカートガードの一方に設けられ、前記スカートガードの他方に向けて検出波を発し、前記踏段が当該検出波の進行方向に存在しない場合は当該検出波を検出せず、前記踏段が当該検出波の進行方向に存在する場合は前記踏段の踏板とライザーとの交わり部の側面で反射した検出波を検出するセンサ装置と、前記センサ装置による検出波の検出状態に基づいて、前記踏段の踏板とライザーとの交わり部の浮き上がりを検出する制御装置と、を備えた。【選択図】図1
