Abstract:
An elevator car has an access opening, a car door for closing the access opening, which door has at least one door panel that can be displaced parallel to the access opening, a thrust crank drive for displacing the at least one door panel between an open position and a closed position, an electric motor for driving the thrust crank drive, and a control device for actuating the electric motor. The control device actuates the electric motor so that a displacement velocity of the at least one door panel is substantially constant over the entire displacement path between the open position and the closed position of the door panel.
