Elevator door coupler assembly

摘要

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.

1. An elevator door assembly, comprising:
a car door subassembly comprising:
a car door;a first vane supported for movement relative to the car door;a second vane supported for movement relative to the car door; anda door mover; a hoistway door subassembly comprising:
a hoistway door;a locking member configured to selectively lock the hoistway door; anda coupler member associated with the locking member, wherein, when the car door is in a position adjacent the hoistway door:
the first vane is configured to be moved, relative to the car door, by the door mover so as to position the first vane in contact with the coupler member and thereafter to cause movement of the coupler member such that the locking member moves into an unlocked position prior to movement of the car door and the hoistway door from a closed position toward an open position; andthe second vane is retained in a non-blocking position by the coupler member when the car door and the hoistway door move from the closed position toward the open position, and wherein, the second vane moves into a blocking position in which further movement of the car door is inhibited when the car door is in another position different than the position adjacent the hoistway door and the car door moves toward the open position.
