A turnstile entry gate comprising at least two, at equiangular distances on an arm carrier (5) mounted barrier arms (2-3), the arm carrier (5) being by way of a remote-controlled barrier device (6) arranged to permit or to prevent turning in at least one rotational direction. The arm carrier (5), or at least one of disks (7; 8) arranged near and connected thereto exhibits a magnetic strip (9) preferably extending circumferentially and adapted, by way of sensors, to indicate the position and the direction of movement of the turnstile. The barrier function of the device (6) is normally mechanically disconnected when one of the barrier arms (2-4) in the turnstile is in its home position, i.e. horizontally oriented, the sensor and electronic systems only checking that a passage has taken place and that, with the aid of e.g. a spring and/or hydraulics, the turnstile can assume its next home position. |
