Abstract
A cable safety barrier has means for disengagement of the cable from an anchor portion of the cable safety barrier when certain vehicle impact conditions are met. Disengaging of the cable may involve allowing a cable end fitting to escape from an open ended slot, when the cable is deflected upwards, or causing the cable fitting to fail.
Claims15
A safety barrier comprising a series of posts, at least one cable which is supported by the posts so as to extend along the series of posts and which has an end portion extending downwards beyond the series of posts, an anchor body securable to a substrate beyond the series of posts, and an attachment means for attaching the end portion of the cable to the anchor body, the attachment being fixed on said end portion, and the anchor body having disengagement means for causing the attachment to disengage the cable from the anchor body in response to a predetermined deflection of said end portion of the cable, said disengagement means being adapted to shear the attachment so as to cause said attachment to fracture under tension applied by the cable when said end portion of the cable is deflected by a predetermined amount.
A safety barrier comprising a series of posts, at least one cable which is supported by the posts so as to extend along the series of posts and which has an end portion extending downwards beyond the series of posts, an anchor body securable to a substrate beyond the series of posts, and an attachment for attaching said end portion of the cable to the anchor body, the attachment being fixed on said end portion, the anchor body having a first abutment surface facing away from the series of posts and the attachment having a second abutment surface facing the first abutment surface, the abutment surfaces being urged towards each other by tension applied to the cable, and the anchor body having disengagement means for allowing the attachment to escape from the anchor body in a direction parallel to the abutment surfaces in response to a predetermined deflection of said end portion of the cable, thereby to disengage the cable from the anchor body.
