Abstract:
A turnstile entry gate assembly comprising:a gate; a rotatable arm carrier which is rotatable in at least one turning direction; a remote-controlled barrier device operable to selectively permit and prevent the turning of the rotatable arm carrier; barrier arms on the rotatable arm carrier projecting from the carrier and rotatable the carrier and defining barrier arms for the gate; each of the arms being rotatable by the rotatable arm carrier to a home position and away from the home position; magnetic tape coupled with the rotatable arm carrier to rotate therewith; sensors on the gate assembly for sensing the position of the magnetic tape for providing an indication of the position and the direction of rotation of the movement of the rotatable arm carrier, and the gate sensors being operable to determine that a passage past the gate assembly has taken place and that the assembly including the arm carrier and barrier arm has operated so that one of the arms is in a home position; the remote-controlled barrier device being so connected with the sensors and being operable so that a bar function of the barrier device is normally mechanically disconnected when one of the barrier arms is in the home position.
