    Abstract: An end terminal for a guardrail system includes an elongated guardrail beam and a flattening or reshaping device defining a channel having an inlet and an outlet vertically aligned along a longitudinal axis. The guardrail beam is moveable along the longitudinal axis through the channel from the inlet to the outlet. An anchor is vertically spaced below the outlet, with a tether coupled between the anchor and an end portion of the guardrail beam. The tether is adapted to pull the guardrail beam downwardly from a first height at the outlet to a second height vertically spaced from the first height free of any engagement with any other structure once the guardrail beam exits the outlet, and with a bending of the deformed guardrail beam in only one direction after the deformed guardrail beam leaves the outlet. Methods of assembly and operation are also provided.

  • Patent number: 8177194
    Abstract: This invention relates to guardrails and guardrail impact heads for use in roading networks or vehicle road lanes requiring separation by a barrier. The invention provides an impact head for a guardrail including cable routing means adapted to form a convoluted path through which a cable can be threaded. The convoluted path that the cables must follow through the impact head of the invention restricts movement of the cable through the head, thereby providing sufficient friction to slow down the movement of the impact head during a vehicle impact. The invention also provides a method of constructing a guardrail including the steps of slidably interconnecting a plurality of rails and attaching them to posts, positioning an impact head according to any one of the preceding claims at one end of the slidably interconnected rails, threading at least one cable through the impact head and anchoring the cable to the ground.

    Abstract: A road safety barrier having a plurality of ropes supported by posts rigidly mounted on or in the ground is described. Each rope is held in tension against the posts and supported in a longitudinally oriented indentation in a side of the posts. The ropes are released from a post and the post is not pulled from the ground when a vertical force is exerted on the rope. The post may have a circular cross-section and the indentation has a bottom oriented substantially parallel to the ground such that the rope is biased to exit upward out of the indentation. The ropes when weaved are tensioned against the posts and this gives rise to a combined frictional resistance to displacement of the ropes relative to each post along the length of the safety barrier.

    Abstract: A highway guardrail post comprises an elongated one-piece roll-formed metal body including a front wall defining an attachment face, a pair of opposing side walls orthogonal to the front wall, a first pair of inverted corners respectively connecting the pair of side walls to the front wall, and a second pair of inverted corners respectively extending from the pair of side walls and terminating in a pair of spaced rear edges to define a rear access opening opposite the front wall. The guardrail posts may be manufactured by roll-forming a metal sheet or coil and cutting the roll-formed metal sheet or coil into lengths.

  • Patent number: 7988133
    Abstract: A combined guardrail and cable safety system is disclosed. In one aspect, a safety barrier incorporating the teachings of the present disclosure may include a plurality of cable posts spaced from each other and disposed adjacent to a roadway. At least two cables may be releasably engaged with and supported by the cable posts. The cable posts and the at least two cables may cooperate with each other to prevent a vehicle from leaving the roadway. A plurality of guardrail posts may also spaced from each other and disposed adjacent to the roadway longitudinally spaced from the plurality of cable post. A box beam guardrail beam may be attached to the plurality of guardrail posts. The at least two cables may operably extend from the cable posts to engage respective cable anchor brackets attached to the box beam guardrail beam.

  • Patent number: 7980533
    Abstract: A breakaway coupling for use with a ground-installed road sign such as a stop sign typically located at the side of a road. The coupling interfaces between a conventional hollow ground stake and a hollow sign post. The coupling can be used with newly installed stop signs, as well as with currently installed stop signs, without modification to either the post of the ground stake. When the sign post is struck by an automobile, the coupling shears along a preformed score section generally aligned with the bottom of the post such that the post and sign break completely from the ground stake and are propelled away from the automobile.

  • Publication number: 20110127480
    Abstract: An energy-absorbing post for absorbing the impact energy of an errant vehicle wherein the impact energy is absorbed by out-of-place deformation in the material of the post. Out-of-plane deformation is provided by utilizing a through bolt extending through a splice connection between upper and lower posts sections. Alternatively, out-of-plane deformation is provided by leaving an axial gap on a splice bolts. For terminal applications, a single through-bolt is utilized to allow the upper post section to pivot during end on impacts. Bolt. tear out facilitators, including stress concentrators and pre-buckles, or an angled through-bolt decrease any initially high tear-out forces.

  • Patent number: 7950870
    Abstract: A non-lethal energy absorbing vehicle barrier for decelerating an impacting vehicle includes a first gate member and a second gate member disposed downstream of the first gate member. The first and second gate members are movable from a retracted position in which the first and second gate members are disposed so as not to impede vehicular traffic on a vehicle pathway, to a deployed position in which the first and second gate members are disposed to impede vehicular traffic on the vehicle pathway. The first gate has a height that is lower than a height of the second gate in the deployed position. Both the first and second gate members include at least a pair of deformable energy absorbing members that are deformed in a substantially inboard direction by a deforming member when the first and second gates are deformed from a pre-impact configuration to an impact configuration.
