Title:
ELEVATOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/179169
Kind Code:
A1
Abstract:
This elevator device is equipped with a sensor 104 that is provided in a car 100 and a car driving unit 101 that drives the car 100. This elevator device measures the distance between the sensor 104 and a landing door 200 while changing the measurement point of the sensor 104 by causing the car 100 to travel and detects if there is an abnormality in the shape of the landing door 200 from the difference between the initial data and the measured distance. Since measurements can be taken while changing the measurement point of the sensor 104, there is no need to install a plurality of sensors per landing door, and it is possible to detect even partial deformation of the landing doors 200 using few sensors.
