Turntable barrier system
First Claim
1. An operable barrier system for vehicles, comprising:
- a turntable configured for use with a trafficable surface;
at least one impact element disposed on the turntable; and
a drive system configured to rotate the turntable along a plane of the trafficable surface between a first position configured to prevent passage by vehicles and a second position, approximately 90 degrees from the first position, configured to permit passage by vehicles.

Abstract
An operable barrier system for vehicles includes a turntable for use with a trafficable surface and at least one impact element disposed on the turntable. A drive system is provided to rotate the turntable along the trafficable surface between a first position to prevent passage by vehicles and a second position, approximately 90 degrees from the first position, to permit passage by vehicles. A method of providing an operable vehicle barrier for use with a roadway includes providing a turntable device having a top surface, mounting at least one impact element on the top surface, and providing a drive system capable of rotating the turntable device in a plane that can be driven across by vehicles from the roadway.

26. A rotatable barrier system for vehicles, comprising:
-
a turntable configured for mounting in a generally planar relationship with a trafficable surface, the turntable having at least one impact element disposed thereon; and a drive system coupled to the turntable and having at least one of a power operated mode and a manually operated mode to rotate the turntable from a first position where the impact element is configured to block passage of vehicles and a second position where the impact element is configured to permit passage of vehicles.
