  • Turning blocking device
    Patent number: 6170194
    Abstract: A method of blocking passage of a user through a passageway comprising a turnstile with a housing; a drive and a locking element in which a barrier arm is set in motion following verification of the access authorization of a user wishing to pass, rotating the barrier arm from its blocking position into a position out of line of passage. The advance of the user is then detected by a downstream sensor, in particular an opto-electronic sensor, which causes the barrier arm to rotate further in the same direction into the blocking position.
    Type: Grant
    Filed: June 15, 1999
    Date of Patent: January 9, 2001
    Assignee: Skidata Computer (yesellschaft m.b.H.)
