Abstract: The invention relates to an automatic door system including a first door leaf of a first door leaf arrangement that can be displaced in the longitudinal direction. A floor-side guide rail arrangement extends in the longitudinal direction and includes a first floor rail arrangement. The at least one first door leaf includes an engagement element which is arranged on an underside of the at least one first door leaf. The at least one first floor rail arrangement includes at least one first floor rail and at least one connection and/or functional element, wherein the at least one connection and/or functional element is arranged on an end side of the at least one first floor rail. The at least one first floor rail includes at least one first guide groove extending in the longitudinal direction.

Abstract: A drive apparatus for a rotor of a revolving door, wherein the drive apparatus includes a drive device, which is motion-coupled to the rotor via a drive belt. The drive apparatus further includes a tensioning device for tensioning and deflecting the drive belt, wherein the drive belt connects the drive device, the tensioning device and the rotor. The tensioning device and/or the drive device are mounted with a variable distance between one another, so that an extension of the drive belt caused by acceleration or deceleration of the rotor is compensated by varying the distance between the tensioning device and the drive device.

Abstract: The present invention discloses a drive device for a rotor of s carousel door, In addition to a main drive motor (10), which has a main-drive-motor shaft (12), the drive device according to the invention comprises a secondary drive motor (12) with a secondary-drive-motor shaft (22). The main-drive-motor shaft (12) is coupled at least indirectly to the secondary-drive-motor shaft (22, 62) in terms of rotation, and therefore the secondary-drive-motor shaft (22, 62) is coupled to the rotor in terms of movement.

The drive apparatus further comprises a tensioning device for tensioning and deflecting the drive belt, wherein the drive belt runs via the drive device and via the tensioning device. The tensioning device and/or the drive device are mounted with a variable distance between one another, so that an extension of the drive belt caused by acceleration or deceleration of the rotor is compensated by varying the distance between the tensioning device and the drive device.
