Abstract:
1. A terminal post for a barrier, the post comprising: an upright portion in the form of an I-beam comprising two parallel flanges connected by a web, said upright portion having a ground engaging portion and an aperture, the aperture being the web in a region of the upright portion above the ground engaging portion; a transverse reinforcing member located on one side of the aperture, said transverse reinforcing member including a slot for receiving a cable, wherein the slot is dimensioned to retain a terminal end of the cable and the aperture is dimensioned to allow the terminal end of the cable to pass through the aperture and wherein when the post is viewed side on, the aperture and the transverse reinforcing member are separated by a set distance which provides a sufficient gap through which the terminal end of the cable can pass, in order to exit the post, upon deformation thereof; and a groove or a pair of notches defined by the upright portion, said groove or pair of notches being located beneath the aperture and forming a predetermined fail line along which the post will fail upon receiving a substantially inline impact, which causes the transverse reinforcing member to move so as to release said terminal end of the cable from the slot and allow the terminal end to pass through the aperture to release the cable from the upright portion.
