Door system

A door system for an elevator, the door system having a shaft door, a car door, a car door drive and a door coupling that couples the car door to the shaft door, the car door and the shaft door when coupled being movable between an open position and a closed position, the door system comprising:

• the car door having an electrically activated car door lock that locks and unlocks the car door when the car door is in the closed position;
• the shaft door having an electrically activated shaft door lock that locks and unlocks the shaft door when the shaft door is in the closed position;
• wherein the car door drive includes a motor and a drive means, the drive means moving the car door from the closed position to the open position and back to the closed position;
• wherein the door coupling has a first part arranged on the car door and a second part arranged on the shaft door;
• wherein the second part of the door coupling has a vertically aligned first guide web projecting from the shaft door and a vertically aligned second guide web projecting from the shaft door, the first and second guide webs being arranged at a fixed guide web spacing from one another;
• wherein the first part of the door coupling has a contact body, the contact body having a length dimension along a length direction that is greater than the guide web spacing, and the contact body having a width dimension along a width direction that is smaller than the guide web spacing;
• wherein the contact body is arranged rotatably on the car door between the first guide web and the second guide web when the car door and the shaft door are arranged together;
• a lever connected to the drive means and the lever being rotationally fixed to the contact body;
• and
• wherein the contact body is rotated, by movement of the drive means, from a decoupled position in which the contact body is arranged between the first and second guide webs with play due to the width dimension being smaller than the guide web spacing, into a coupling position in which the contact body touches the first and second guide webs.
