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 apparatus for a rotor of a revolving door, wherein the drive apparatus comprises a drive device, which is motion-coupled to the rotor via a drive belt. 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.

Abstract: An apparatus for the insertion and withdrawal of a plug-in module with front panel into and out of a module carrier includes a lever arm (2) pivotable about an axis (3) with a handle portion (2a) for the rotation of the lever arm as well as a bolt (5) to lock the lever arm and an operating element (5a) connected to the bolt with which the lever arm can be unlocked. The operating element (5a) is arranged spaced from the lever arm (2), and the handle portion (2a) is designed such that it contacts the front panel (10) of the plug-in module in the inwardly pivoted position.
