Abstract
An elevator door system has a shaft door, a car door, a car door drive and a door coupling that couples the car door to the shaft door. An electrically activated car door lock, locks and unlocks the car door in a closed position. The door coupling includes a contact body with a length dimension greater than a spacing between a pair of guide webs and a width dimension smaller than the guide web spacing. The contact body is arranged rotatably on the car door between the guide webs and a lever is connected to a drive means and rotationally to the contact body, the contact body being rotated by a movement of the drive means from a decoupled position, in which the contact body is arranged with play between the guide webs due to the width dimension, into a coupling position, in which the contact body touches the guide webs.
