Abstract:
PROBLEM TO BE SOLVED: To detect that a pair of parallel members provided at a landing door and roller members provided in a car door are interfered with each other in the positional relationship in an elevator door device.SOLUTION: An elevator door device 10 includes: a landing door 12 openable/closable when a car 16 is landed; a pair of parallel members 14 provided in a car door 18 of the car 16 with a prescribed interval so that a longitudinal direction coincides with an elevating/lowering direction of the car 16; roller members 20 provided in the landing door 12 in an arrangement relationship that the roller members 20 can approach between the pair of parallel members 14 with a prescribed interval when the car 16 is normally landed; an inclination detection section 22 for detecting an inclination angle in relation to the elevating/lowering direction of the car door 18; and a determination section 24 for determining whether the inclination angle exceeds an inclination threshold in which the car door 18 is inclined and the roller members 20 and the pair of parallel members 14 are interfered with each other. The inclination threshold is defined on the basis of the prescribed interval and the height of the car door 18.
