Title:
ELEVATOR DOOR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/141384
Kind Code:
A1
Abstract:
The purpose is to provide an elevator door control device capable of automatically determining whether or not a closer device is capable of causing the boarding area door to self-close. In order to achieve the above, the present invention is provided with: an elevator car door panel and a boarding area door panel for opening and closing the entrance/exit of the elevator car and the entrance/exit of the boarding area, respectively; a motor for driving the opening/closing of the elevator car door panel; a linking means (40) for mechanically linking the elevator car door panel and the boarding area door panel so that the two door panels open and close integrally; a closer device (36) for applying a self-closing force, acting in the door-closing direction, to the boarding area door panel; and a control means for controlling the motor. The control means is provided with: a torque detector (51) for detecting the torque of the motor when the two door panels are opening and/or closing in a state in which the two door panels are linked; and a determination unit (53) for judging, on the basis of the torque detected by the torque detector, whether or not the boarding area door panel can be caused to self-close by the self-closing force in a state in which the two door panels are not linked.
