Abstract
The traffic barrier was designed to give law-enforcement officers an effective traffic barrier which can be easily carried in the trunk of a car and quickly deployed across a roadway and just as quickly, removed from the roadway as the situation warrants. There is no need for assembly or mechanical procedure, the chain is simply stretched across the roadway at a right angle to the direction of traffic and pulled taut. The traffic barrier chain is designed so that no matter how the chain is placed on the road surface, half of the splines will be facing the direction of the traffic flow at an angle of 45 degrees. The other half will be facing the other direction. Deployment of the traffic barrier chain is a preferable option to using an expensive patrol car for a road block, or attempting to shoot out the tires or radiator of a vehicle. The traffic barrier chain would be a useful addition to the entries of security facilities where traditional gates are vulnerable to breech by ramming with a vehicle.
