Abstract:
A method of modernizing the car door system of a elevator car, which originally comprises at least one car door leaf, a door drive with a crank gear and a drive linkage displacing the car door leaf and a car door/shaft door coupling actuated by the drive linkage, with the following method steps: demounting the door drive together with the crank gear and the drive linkage, mounting a door drive with a linearly moved drive means and coupling of the drive means with the car door leaf of the original car door system, and mounting an actuating device for actuating the car door/shaft door coupling.
