ABSTRACT:
Elevator doors have operating bars that are pivoted on a car door and that serve to actuate shaft-door actuating rollers that operate shaft doors. These doors are operated by an apparatus having an actuating device that changes a spacing between the operating bars and that has an actuating lever coupled with a door actuator. This actuating lever is coupled with a first link pivoted on the operating bars. The actuating lever and the first link are pivotal through a predetermined angle. A latch for the car doors is provided with a tension element connected between one operating bar and the actuating lever.
