A personnel access-control device in the form of a turnstile (1) has one or more blocking arms (2, 3) connected to a main shaft (5) mounted in a carrier (4). The blocking arms (2, 3) assume a blocking position and at least one free position in dependence upon the rotation of the main shaft (5). Each blocking arm (2, 3) includes a flat component (6, 7) that is mounted to rotate about its longitudinal axis (8, 9) in dependence upon the rotation of the main shaft (5). In the blocking position of the blocking arms (2, 3), a pre-defined angular position of the flat component (6, 7) with respect to the perpendicular direction is achieved, and in the free position, the flat component (6, 7) is rotated such that passage of a person is allowed and/or that the passage width is not limited. |
