Abstract (en)
[origin: WO9008875A1] A turnstile has a rotary disk (3) which can be held in each blocking position by a catch device (10) and an elastic rotary coupling (8) between the rotary disk (3) and the catch device (10). The turnstile also comprises an angle of rotation identification system (11) which locks the catch device (10) in each blocking position and a brake (9) which functions only in the event of unauthorized rotation of the turnstile. The elastic rotary coupling (8) enables a system (7) which identifies the direction of rotation to detect an unauthorized rotation even when the catch device (10) is locked. When the system (7) for detecting the direction of rotation detects an authorized rotation, the catch device (10) is released, and when it detects an unauthorized rotation, the brake (9) is activated.
