Door system for an elevator car, elevator system and method for evacuating an elevator car

A door system for an elevator car, wherein the elevator car is movable in an elevator shaft between several floors and has a car opening, the door system comprising:

• a door leaf adapted to close at least a partial region of the car opening when mounted on the elevator car;
• a mounting device adapted to mount the door leaf on the elevator car for slidable movement of the door leaf in a direction of a sliding axis between an open position, in which the door leaf releases the partial region, and a closed position, in which the door leaf closes the partial region, the mounted door leaf being additionally rotatable about a rotation axis so that the door leaf when in the closed position and/or in an intermediate position between the open position and the closed position is rotatable into an emergency open position in which the car opening is released such that the elevator car can be evacuated through the car opening;
• wherein the mounting device includes a folding part and a sliding part;
• and
• wherein the sliding part is adapted to mount on the elevator car to slide in the direction of the sliding axis between the open position and the closed position, wherein the folding part is mounted on the sliding part to rotate about the rotation axis such that the folding part is slidable together with the sliding part, and wherein the door leaf is fastened to the folding part such that the door leaf is rotatable together with the folding part.
