  • Patent number: 8043024
    Abstract: A light weight, high strength cable supported by a longitudinal device that is capable of stopping a 15,000 lb vehicle at speeds exceeding 30 mph and provides for manual operation by one (1) person, whereas the barrier may pivot, move vertically, or swivel horizontally to control vehicle passage. Typically, the cable is embedded within a longitudinal support device and remains concealed. During normal operations where the vehicle barrier is moved, there is no tension on the cable and it remains unfastened. If a vehicle impact occurs, the cable immediately engages and fastens to the end support structures to resist vehicle impact forces. The light weight cable and longitudinal support device provides span distances exceeding 24 feet across a vehicle travel path, while requiring only one (1) person to manually move the barrier. The light weight cable and longitudinal support device also minimizes the counterweight size. The barrier may be moved by an operator from either side of the vehicle travel path.

    Abstract: In order to stop a moving vehicle without injury to occupants, a vehicle barrier is provided having a pair of platforms disposed on opposite sides of a roadway, and a capture net extending across the roadway between the platforms. Each platform has a rotatably mounted spool attached to a different end of the net, and a dual acting extension-compression shock absorber pivotally mounted to the spool, such that when the force or energy of an impacting vehicle on the net is applied to the shock absorbers, via rotation of the spools. Rotation of spools operate the shock absorbers in compression, and if needed, in extension. In railroad crossing application, two of the vehicle barriers are provided on either side of the railroad tracks to prevent vehicles from crossing the railroad tracks.

  • Patent number: 7125197
    Abstract: A vehicle capture net disposed between a pair of towers each of which includes a shaft, a pair of spools coupled to the shaft, and a pair of straps connected to the net. Each strap is wound on a spool. A brake is coupled to the shaft and to the spools for providing a restraining force of increasing magnitude as the straps are unwound. Unwinding of the straps from the spools advances the pair of spools on threaded portions of the shaft to compress the adjacent braking surfaces against each other. The vehicle is stopped by deploying a vehicle capture net connected to at least one pair of straps each wound on a spool, permitting the vehicle to collide with the capture net and to unwind the straps from corresponding spools, and providing a restraining force of increasing magnitude on the straps as the straps are unwound from the spools.

  • Patent number: 6969185
    Abstract: A safety net that includes at least one illuminating element. The safety net is intended to be stored in a rolled-up fashion (similar to a roll-up window shade) in the trunk of a vehicle. When illuminated, the safety net provides a completely new and unique means of alerting oncoming traffic to a road hazard or other situation requiring traffic control. The safety net provides a warning means that will not be knocked over by the wind, as wind blows freely through the voids of the net. In addition, the safety net screens the scene from the view of those in oncoming traffic. The device may include a solid state controller that provides a variety of patterns or symbols to further enhance the visual safety features of the device. This can be accomplished by placing fiber optic strands in the net voids, or within the side illuminating fiber optic conduit itself. The device may also include metal cables to form a physical barrier.
