Abstract:
1. A personnel access-control device having a stationary carrier and a rotatable gate with at least two linear blocking arms each having only a single longitudinal axis, said gate being mounted for rotary movement with respect to the carrier about a main axis that is angled with respect to a vertical, said main axis being at an acute angle with respect to said axis of each of said blocking arms, wherein the at least two blocking arms are rotatable about said main axis between a blocking position in which at least one of the blocking arms blocks passage of a person through the device and at least one free position in which the at least one of the blocking arms allows the passage of said person through the device, wherein flat components are mounted to said blocking arms for rotary movement about said main axis and the longitudinal axes of the associated blocking arms, said rotary movement of said flat components about said longitudinal axes of the blocking arms being coupled with the rotary movement of the gate about the main axis such that as the gate rotates about the main axis, the blocking arms and the flat components are rotated about the axes of the blocking arms by at least one motor, whereby when the at least one of the blocking arms is in the blocking position the flat component thereof is at a first defined angle with respect to the vertical to present a barrier to the passage of the person through the device and when the at least one of the blocking arms is in the free position the flat component thereof is at a second defined angle with respect to the vertical to allow the passage of the person through the device.
