エレベーター
Document Type and Number:
Japanese Patent JP6811165
Kind Code:
B2
Abstract:
To provide an elevator capable of preventing such an erroneous detection that an upper end part or a lower end part of a door part is normal even in a state where a gap is generated in the upper end part or the lower end part.SOLUTION: The elevator includes a car, a door part 11A, an upper part detection switch 40, a lower part detection switch 40, and a control part. The upper part detection switch 40 outputs an upper part door closing detection signal when it is detected that the door part 11A is moved to a closing end position T1 at an upper end part 11a in the vertical direction in the door part 11A. The lower detection switch 50 outputs a lower part door closing detection signal when it is detected that the door part 11A is moved to the closing end position T1 at the lower end part 11b in the vertical direction in the door part 11A. The control part determines that the car can be moved up/down when receiving both of the upper part door closing detection signal and the lower part door closing detection signal.SELECTED DRAWING: Figure 3
