Car and Hoistway Door Coupling Apparatus Abstract An apparatus is provided which couples a car door and a hall door in an elevator system. The apparatus includes a roller which is spring loaded into a first position for engaging a vane on the car door and which is movable from that first posi- tion for disengaging the vane if the vane is on the wrong side of the roller. The apparatus allows the car door to open and close the hall door by engaging this roller and, if the vane is on the wrong side of the roller, nevertheless, allows the car door to close.
