The revolving door frame (6) of components has a drive motor (7) with driven shaft (8) connected to a mechanism part positioned on the night-time barrier (5) and the same width as the barrier. The barrier has a toothed belt (10) engaging with a driven pinion (9) of the drive mechanism (7). The toothed belt is positioned on the outer surface (11) of the night-time barrier. The drive mechanism drives the toothed belt via pressure rollers (12) beside the driven pinion. The night-time barrier is suspended by a roller guide (13) from the revolving door frame. |
