Door drive for a door, in particular of a piece of furniture or an appliance, method for operating such a door drive as well as device with at least one such door drive

A method of operating a door drive of a door, the method comprising:

• driving the door by a door drive, and
• moving the door from a first position into a second position in relation to a housing element,
• wherein the door drive comprises:
• a drive motor,
• a drive shaft which, in driving the door, is driven and thereby rotated by the drive motor,
• a clutch, and
• a threaded spindle which, in driving the door, is driven and thereby rotated by the drive shaft via the clutch whereby the door is driven by the drive motor via the threaded spindle, the clutch and the drive shaft,
• wherein
• the clutch comprises:
• a catch element,
• an actuating element which, by rotating the drive shaft, is driven and thereby rotated around an actuation rotational axis by the drive shaft, the actuating element comprising at least one first actuation area, and
• a clutch element which comprises at least one second actuation area corresponding to the first actuation area, wherein the clutch element is translationally movable along the actuation rotational axis relative to the catch element between at least one decoupling position in which the clutch element is decoupled from the catch element, and at least one coupling position in which the clutch element is coupled to the catch element, and wherein a relative rotation between the actuating element and the clutch element, the relative rotation being effected by rotating the drive shaft, is converted, by the actuation areas, into a translational movement of the clutch element from the decoupling position into the coupling position, the translational movement taking place along the actuation rotational axis, relative to the catch element, relative to the actuating element and in the direction of the catch element;
• wherein the clutch element is rotatable in relation to the housing and translationally movable between the coupling position and the decoupling position, wherein at least one brake element formed separately from the clutch element is provided, and wherein by the brake element the clutch element can be braked against the housing at least with respect to the clutch element's rotation taking place in relation to the housing;
• wherein at least one first surface of the brake element directly contacts at least one second surface of the clutch element.
