- An upper stopper 24 is provided at the upper edge of the car doorway.
- the upper stopper 24 is provided above the front end portion of the movable guide 22.
- FIG. 2 is a diagram for explaining the operation of the elevator door device according to Embodiment 1 of the present invention.
- position A corresponds to one fully closed position of the car door 1.
- Position B corresponds to a preset operating position. For example, the operation position is set near one fully opened position of the car door 1.
- the position C corresponds to one fully open position of the car door 1.
- the connecting rod 18 moves upward.
- the slide roller 21 moves upward.
- the slide roller 21 lifts the first slide device 12.
- the detection bar 11 moves in the opening direction of one of the car doors 1 with respect to one of the car doors 1.
- the detection bar 11 becomes a state equivalent to the state when the obstacle is detected.
- the switch 14 operates. Based on this operation, the control device 15 determines that the detection bar 11 has not been turned off. When the switch 14 does not operate at the position B, the control device 15 determines that the detection bar 11 has an off failure.
- the guide roller 20 gets over the movable guide 22. At this time, the guide roller 20 moves downward due to its own weight. Following the movement, the connecting rod 18 moves downward. Following the movement, the stopper 19 moves downward. At this time, the stopper 19 contacts the upper guide 17. The contact stops the movement of the connecting rod 19. At this time, the height of the guide roller 20 is the same as the position A. The slide roller 21 releases the lifting of the first slide device 12. By the cancellation, the detection bar 11 returns to a state where no obstacle is detected.
- FIG. 3 is a diagram for explaining the operation of the elevator door device according to the first embodiment of the present invention.
- position D corresponds to one fully open position of the car door 1.
- position E corresponds to a preset operation position.
- the operation position is set near one fully opened position of the car door 1.
- the position F corresponds to one fully closed position of the car door 1.
- the car door 1 goes to position F.
- the detection bar 11 maintains a state where no obstacle is detected.
- the detection bar 11 moves in the opening direction of one of the car doors 1 with respect to one of the car doors 1. Specifically, when the guide roller 20 rides on the movable guide 22, the detection bar 11 moves in one opening direction of the car door 1 with respect to one of the car doors 1. For this reason, it can be easily determined that the detection bar 11 has not failed at a timing at which the detection bar 11 does not need to detect an obstacle.
- the detection bar 11 is released from the movement of one of the car doors 1 in the opening direction with respect to one of the car doors 1. For this reason, before the pair of car doors 1 is closed, the state of the detection bar 11 can be returned to the state where no obstacle is detected.
- control device 15 determines the failure of the detection bar 11 based on the movement result of the detection bar 11 when one of the car doors 1 is opened. For this reason, it can be easily determined that the detection bar 11 is out of order at a timing when the detection bar 11 does not need to detect an obstacle. As a result, it is possible to quickly detect a state in which an obstacle cannot be detected even if the detection bar 11 operates.
- the detection bar 11 maintains a state where no obstacle is detected. Specifically, when the pair of doors 1 are closed, the movable guide 22 rotates according to the movement of the guide roller 20. For this reason, the height of the guide roller 20 does not change. As a result, it is possible to prevent the obstacle from being erroneously detected by the operation when detecting the failure of the detection bar 11.
- a position other than the vicinity of one fully opened position of the car door 1 may be set as the operating position.
- the vicinity of one fully closed position of the car door 1 may be set as the operating position.
- the door device for an elevator according to the present invention can be used for an elevator that determines that the detection bar has not failed.
