Abstract
A guide system includes a first guide rail for guiding a door wing, a second guide rail for guiding the door wing. A carrier can move the door wing relative to the second guide rail in a direction extending transversely to the longitudinal direction of the first guide rail. A drive device has a force storage member, and the carrier can be at least partially ejected by the drive device from the retracted position of the carrier by a force of the force storage member. The drive device includes a coupling portion and a control curve, and the coupling portion and the control curve are decoupled over a large part of the movement of the carrier between the extended position and the retracted position. The carrier can be retracted into the retracted position starting from a position immediately before the retracted position when the coupling portion couples with the control curve.
