ABSTRACT:
A device for controlling the movement of the two doors is housed in a tile-shaped elongate support which is disposed above the doorway and is pivoted about a horizontal axis extending longitudinally of the roof of the car. The tile-shaped support carries centrally an electric motor for rotating two screws which are situated on respective sides of the motor and are threaded in opposite directions. A nut is mounted on each screw to run longitudinally, and has a forked part which engages a draw-bolt carried by the respective door of the doorway. When the tile-shaped support is pivoted upwardly by hand from outside the car, each fork is disengaged from its respective bolt to allow the emergency opening of the doors.
