  • Publication number: 20100207087
    Abstract: A guardrail includes a cable routing device providing a tortuous path for at least one tensioned cable, the cable routing device includes a bar having a rotational axis and including a cable entry port having a circumference slightly larger than the cable which passes directly therethrough when the bar is in a first non-cable gripping orientation in which the diameter of the port (diametric width) is substantially orthogonal to the longitudinal axis of the cable, and wherein rotation of the bar about the axis effectively decreases the width of the port relative to the width of the cable to create a second cable-gripping orientation which provides the tortuous path, wherein the tortuous path through the bar is due to the relative decrease in the effective diametric width of the port and this provides sufficient frictional resistance to movement in relation to the cable during impact to facilitate impact energy dissipation.

  • Patent number: 5203543
    Abstract: A bracket for mounting a roadway guardrail to a post adjacent a roadway involves a generally rectangular backing member having an inwardly-extending flange extending along each of the upper and lower edges thereof. The bracket can be interposed between, preferably, a W-shaped guardrail and the post with the upper and lower edges of the guardrail being located adjacent the upper and lower flanges of the bracket respectively. The normal guardrail-mounting bolt will extend through the guardrail, a central aperture in the bracket, and the mounting post for clamping the guardrail end bracket to the post. Upon the impact, particularly sliding impact from a snowplow or the like, the upper and lower edges of the guardrail will contact the flanges and further deformation thereof will be resisted by the flanges. Thus the guardrail which would otherwise be detrimentally deformed by minor impacts will now retain its shock-absorbing capabilities, such detrimental having been resisted by the back of the invention.

    Abstract: A collapsible roadway impact attenuator includes an array of spaced parallel support elements arranged to move axially when the attenuator is struck by impacting vehicle. Elastomeric energy absorbing sheets are rigidly secured between adjacent support elements so as to extend axially and horizontally. When the attenuator is struck axially by a vehicle, the support elements move towards one another and the energy absorbing sheets form at least three inflections, thereby enhancing energy absorbing efficiency of the attenuator. Tethers can be mounted between overlying elastomeric sheets to increase the number of inflections and the energy efficiency of the attenuator.

  • Patent number: 4941633
    Abstract: A support device which is particularly adapted to join a length of rope to a structural member of a building, for example, has a body prepared for ready attachment to the structural member. Projecting outwardly from the body of the device is a set of spaced apart clips. Each clip is defined by an outer strap spaced from the device body and joined thereto by a connecting strap to form a holding area for the rope. The clips are positioned in an opposing manner so that each clip holding area faces in an opposite direction. The outer strap of each clip has an angularly offset wall. These walls are spaced apart and positioned parallel to form an opening to a rope passageway defined by alignment of the clip holding areas. During use the support device is attached to the structural member and an end of the rope length threaded through the passageway to seat in the clip holding areas and be supported horizontally therein.

  • Patent number: 4838523
    Abstract: An improvement to an energy absorbing guard rail terminal for use on longitudinally extending roadways. The energy absorbing guard rail terminal having a number of overlapping horizontally extending parallel guard rails positioned on oppositely disposed sides of a plurality of longitudinally spaced break away posts with the upstream ends of the guard rails secured to the post. Splice bolts connect the overlapping ends of adjacent rails which are characterized by a plurality of openings within each horizontal rail aligned with the splice bolts whereby the impact of the vehicle on the upstream end of the rails will force the bolts to shred out the rail material between the openings within the rails. By absorbing the kinetic energy of the impacting vehicle, the collapseable guard rail terminal allows for safe deceleration of the vehicle upon impact, avoiding serious injury to the driver.
