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