ABSTRACT:
A linkage is provided for joining a car door to a hoistway door, the linkage having a lever attached about a middle portion thereof to one of the car or hoistway doors, the lever having a roller disposed at an end portion thereof for fixedly engaging the other of the car or hoistway doors, the lever cooperating with a linkage connected to the door operating unit to allow the rollers to engage the other of the car or hoistway doors without moving the other of the car or hoistway doors. A latch cooperates with a linkage connected to the door operating unit to allow the car doors to close without disengaging the rollers from the vane and for allowing the rollers to disengage the vane after the doors are closed.
