Abstract:
Elevator door coupling systems are described. The systems include a car door lock having a coupling element and a lock element, the lock element operably connected to a latch for locking the car door lock and a landing door lock having a movable plate, a first contact element mounted to the movable plate and configured to engage with the coupling element and a second contact element configured to engage with the lock element. In operation, the coupling element is operable to apply force to the first contact element and cause the movable plate to rotate and as the movable plate rotates, the second contact element applies force to the lock element to urge the latch from a locked position to an unlocked position.
