Abstract

In the present invention, a door apparatus and an elevator apparatus are provided with an engaging means (19). In a state where the elevator car has arrived at the boarding area, the engaging means, by means of the action of the car door, causes the car door and the boarding area door to engage, and by means of this engagement the driving force of the car door is transmitted to the boarding area door, and, in response to the release of the engagement, a door locking means (28) is caused to operate. The engaging means is provided with the following: a fixed vane (19a) located on the car door doorstop side; a moveable vane (19c) that is kept parallel with the fixed vane and fixed to the car door pocket side via a link mechanism (19b); and moveable-vane open and close mechanisms (19e, 19f) that vary the distance between the fixed vane and the moveable vane. The moveable-vane open and close mechanisms control the operation of the moveable vane on the basis of electrical door position information, without the need for a special cam.

Description

technical field [0001] The present invention relates to an elevator door device and elevator equipment, in particular to a center-split elevator door for controlling the distance between the fixed wing and the movable wing of the engaging device of the elevator car door Elevator door devices and elevator equipment for side-opening elevator doors. Background technique [0002] In high-rise buildings, especially in winter when there is a temperature difference between indoors and outdoors, there will be a strong updraft in the elevator hoistway. around the hall door. As a result, the wind pressure acting on the surface of the hall door increases, and when the elevator door is about to be completely closed, in the area where only the self-closing force of the door closer spring on the hall door can play a role, it may happen that the hall door cannot be fully closed. Closed situation. [0003] As a solution to this problem, a solution is known in the prior art, which mechani...
