ABSTRACT:
In a security revolving door assembly for persons, comprising one blocking sector (13) and one passage sector (12) or two passage sectors (12), a motor-driven revolving door (10), which can be blocked by means of a braking device controllable by an electronic control unit, is arranged in the door housing. Peripheral identification devices (46, 47) are connected to the electronic control unit. To ensure reliable entry and exit control, blocking, which cannot be overcome at certain angular positions of the revolving door (10), but which always makes it possible to leave the door housing, is provided. This is achieved by means of a blocking disk (23) which is in a rigid rotating connection with the revolving door (10) and has, in a blocking plane, at least one stop face pair (26/1-26/2, 27/1-27/2, 28/1-28/2) with two stop faces (26/1 through 28/2), each acting in one reaction direction. Two stationary locking bolts (24 and 25), which can be brought into blocking position between two stop faces (26/1 through 28/2), are associated with the blocking disk (23). Due to their special arrangement relative to the distance between two stop faces (26/1 through 28/2), the revolving door (10) is freely rotatable through half the sector angle of the passage sector (12) when the locking bolt (24, 25) has dropped in.
