Abstract: A canopy device including a drive unit for moving a canopy material and at least two girders that extend in a movement direction of the canopy material and which are spaced apart from each other transversely to the movement direction of the canopy material. The canopy material can be moved from an opened actuating state to various actuating states between the girders. The drive unit is fixed in position and includes a transmission arrangement and an actuating element able to move along a girder, which are coordinated such that a driving action can be transmitted from the drive unit to the actuating element. The actuating element is designed for a connection to the canopy material and is coupled to a gear wheel of the transmission arrangement, which is drivable by the drive unit. The gear wheel interacts with a tooth contour formed along the girder.
