  • Patent number: 8282309
    Abstract: An inertial barrier includes a standard size plastic container and a single size insert that is supported by a ledge inside the container for supporting different amounts of sand or other dispersible granular energy absorbing material thereon to achieve different barrier weight configurations. The insert has an axially upwardly, radially inwardly extending top wall that permits some downward flexing of the insert inside the container as the weight of the material that is placed on the insert builds up, causing the sides of the insert to expand and push radially outwardly against the container side wall, preventing the material from leaking past the insert inside the container. Axially extending ribs may be provided in the container side wall for increased strength and rigidity.

  • Patent number: 7901156
    Abstract: A plate-mounted bollard which includes an internal impact absorption mechanism that enables the bollard to absorb impact forces greater than conventional plate-mounted bollards. The bollard makes use of a force transfer process that shifts impact forces to areas better able to resiliently absorb the impact without causing damage to the bollard, the impact absorption mechanism, or the ground in which the bollard is installed. The impact absorption mechanism consists of an internal resilient core rod mounted at its proximal end to a base plate which is fixed to the ground. Impact forces are then transferred through an outer shell to the distal or upper end of the internal resilient core. With energy from the impact force being distributed along the maximum length of the resilient core rod, the rod flexes and the full length of the rod is utilized to absorb the impact energy.

  • Patent number: 7785031
    Abstract: A heavy duty ground retractable automobile barrier for a railroad crossing. Concrete bunkers are placed at each side of a roadway. An upstanding concrete-filled steel pipe fixed in each bunker has a sleeve for rotational and axial movement. Shock absorbers are mounted on each sleeve. A net extends across the road and is attached to the opposite ends of the shock absorbers. Collision of an automobile with the net creates tensile forces in the net. The shock absorbers expand while rotating about the pipe's axis in response to tensile forces from the net that meet or exceed a minimum threshold. Forces from the net pass through the axis of the steel pipe. The net is stored in a pit transverse the roadway parallel to the railroad tracks and is raised and lowered as appropriate. The net includes a cable that extends across the road in a wave pattern, having peaks, valleys and midpoints, wherein tangents of the wave midpoints are at least 90 degrees from tangents of the peaks and valleys.

  • Publication number: 20100202830
    Abstract: The invention relates to a device reducing speed of vehicles travelling on a roadway, formed by at least one strip of flexible material, rubber or other similar material, made up of several hollow chambers which are interconnected by a calibrated conduit which enables the controlled passage of the fluid filling said chambers from that flattened by the wheel of the vehicle towards the adjacent chambers. The fluid contained therein is water, or a non-Newtonian fluid offering the higher viscosity, the higher the stress gradient applied thereto is, the fluid itself acting as means for controlling the resistance to deformation of the strip as the higher is the speed of impact of the vehicle in said strip.

  • Patent number: 7726056
    Abstract: There is provided a knock down signpost comprising a post member (6) and a lower body member (10) held together by a spring (3) having a preload when the post is vertical, acting two flat surfaces (8) creating an initial resistance to motion off the horizontal. Two steel cables (114) transmit the force of the spring and are spaced apart which allows the cables to act as a non rotation mechanism. Two round protrusions (16) in the post member (6) locate into two matching clearance holes (14) in the lower body for post alignment. A shock tube (4) is fitted over the cable and internal to the spring to prevent over compression and provides a mechanical stop. As the top assembly is rotated chamfered edges (15) of the post member (6) engage and interlock into an annular groove (13) to act as a pseudo-hinge.

  • Patent number: 7690859
    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.
