Title: Improvements in and relating to barriers
IPC: G07F17/14
Filed: 1969-10-01
Abstract: 1283975 Turnstiles ETABS GEORGES KLEIN 1 Oct 1969 [2 Oct 1968] 48135/69 Headings G4T and G4V A barrier mechanism comprises a barrier element (3) (Fig. 1, not reproduced) normally unlocked and at rest in a position to obstruct passage, and a locking element 5 (Fig. 2) actuable, on initial displacement of the barrier element (3) by unauthorized persons or objects, to lock the barrier element (3) in its rest position. As described, the supporting shaft of a turnstile carries a disc 7 having three notches 6 for cooperation with a locking bolt 5, and a second disc 13 having abutments 14-16 for operating pairs of unidirectional, normally open microswitches 11, 27 and 12, 28 that are sensitive to respective directions of rotation of the disc 13. On each passage through the turnstile (3), the discs 4 and 13 rotate through 120 degrees (alternatively, the disc 13 rotates once per passage and carries only one abutment to operate microswitches 11, 27, a second disc serving to operate microswitches 27, 28). Fig. 2 shows the turnstile in its normal rest position. Passage through the turnstile in a first direction begins to rotate the second disc 13 in direction A<SP>1</SP>, whereupon abutment 14 closes microswitch 11. If a series switch 18a is closed by a changeover bar 19, an electromagnet 10 is energized to move the bolt 5 into engagement with a switch 6 in disc 7, and lock the turnstile against further rotation. Similarly, passage in the reverse direction is controlled by a microswitch 12 and series switch 18b. In an alternative embodiment, initial rotation is detected by photo-cells. Passage in the first direction may be authorized by an operator, or by coin insertion, to send one or more authorization pulses to an input 23 of a memory 22, which then opens a switch 21 to prevent energization of electromagnet 10. As the disc 13 reaches the end of a rotation through 120 degrees, microswitch 27 is closed by an abutment 14-16, to send a deduction pulse to memory 22. When the number of deduction pulses (one per turnstile rotation) equals the number of authorization pulses, the memory 22 closes switch 21 to render the electromagnet 10 operative again. Similarly, passage in the reverse direction is authorized by coin insertion, the memory 22, and microswitch 28. A separate memory 22 and switch 21 may be provided for each direction of passage, and the coin insertion slots may be locked against use. In an alternative embodiment (Fig. 4, not reproduced), a pair of microswitches (111) and (112) is attached to the end of each arm (4) of the turnstile (3), to be activated on initial turnstile movement by the pressure of a surrounding and displaceable casing.
