A method of operating a turnstile gate for the purpose of controlling human thoroughfare. A thoroughfare-obstructing structure rotates around a fixed axis and has thoroughfare-obstructing means extending out of it and separated by equal angles. The thoroughfare-obstructing means can be shifted out of their usual state, the operational state, into a non-operational state, as the thoroughfare-obstructing structure rotates. The thoroughfare-obstructing means revolve out of a thoroughfare-obstructing position and into a thoroughfare unobstructing position. Another arm revolves into the thoroughfare-obstructing position whenever the arm directly downstream of it revolves out of the thoroughfare-obstructing position and into the thoroughfare unobstructing position. When a condition, a power failure for example, that interferes with regular operation occurs, at least the thoroughfare-obstructing means currently in the thoroughfare-obstructing position shift out of that position and into a non-operational state that allows continuous thoroughfare. Once the condition resulting in disengagement of the mechanisms that maintain at least the thoroughfare-obstructing means currently in the thoroughfare-obstructing position in the operational state has been eliminated, the means are shifted back into that state by force directed toward the thoroughfare-obstructing structure's axis of rotation and are maintained in that state such that they can be shifted out of it.

Method of operating a turnstile gate

In a security revolving door is provided (1) with a turnstile (2) rotatably through one passage sector (8) and one blocking sector (9), which turnstile can be turned into a defined resting position. An electronic control unit (28) with peripheral monitoring devices is provided to control a blocking device (14) releasing or blocking the rotation of the turnstile (2). The blocking device (14) consist of the simplest possible, identical individual parts, which can be simply adjusted or readjusted to different cases of application and modes of operation. This is achieved by the blocking device (14) having a blocking member (15) which is connected nonrotatably to the turnstile (2). The blocking member is provided with blocking cams (18, 19, 20), whose number corresponds to the number of the cross wings (4, 5, 6), and is associated with two electromagnetically controllable blocking elements (16, 17). One of the blocking elements (16) brings about blocking of the counterclockwise rotation (arrow 22) in cooperation with a blocking cam (18, 19, 20), and the other blocking element (17) brings about blocking of the clockwise rotation (arrow 23) in cooperation with another blocking cam (18, 29, 20), wherein the blocking elements (16, 17) can be mechanically deflected from their blocking position from the blocking cams (18, 19, 20) in the opposite direction of rotation.
