Abstract
An elevator door assembly includes car and hoistway door subassemblies. The car door subassembly includes: a car door, a door mover, and first and second vanes supported for movement relative to the car door. The hoistway door subassembly includes: a hoistway door; a locking member that selectively locks the hoistway door; and a coupler member associated with the locking member. When the car door is adjacent the hoistway door: the first vane moves into contact with the coupler member and causes the locking member to move into an unlocked position, prior to movement of the car and hoistway doors; and the second vane is retained in a non-blocking position by the coupler member. When the car door is not adjacent the hoistway door, movement of the car door toward the open position moves the second vane into a blocking position in which further movement of the car door is inhibited.
