Abstract
A hoistway and a car door are coupled by means of a vane attached to one of the hoistway door and the car door, and a mating channel mounted to the other of the hoistway or car door. A mechanism allows the channel to extend from its mounting towards the vane if the car is in preparing to load or unload passengers. The vane enters the channel to couple the car and hoistway doors for motion together. If the car is in motion the mechanism causes the channel to move towards its mounting and away from the vane so that each channel does not interfere with any vanes on any floor that is passed while in the car is in motion. The channel allows the vane attached thereto, to slightly ascend and descend while still coupled to the channel. The mounting has a spring that bends to move the channel away from the vane and unbends to move the channel towards the vane. The channel releases a lock attached to a hoistway door as the channel moves away from its mounting to allow the hoistway door to open as the car doors open.
