Abstract

See full text

A breakaway coupling for a light pole or the like is disclosed and is utilized on each of the anchor bolts of the foundation for the pole. Each of the couplings comprises a metal coupling nut which has a plurality of radially spaced-apart and vertically disposed slits formed therein which extend thereinto to create weakened areas or zones in the coupling nut. The coupling nut is embedded in a fiber-reinforced material which provides the necessary hoop strength to the coupling nut. The base plate of the pole is positioned on the upper ends of the coupling nuts and is secured thereto by bolts extending downwardly through the base plate of the pole. If the pole is struck by a vehicle, the fiber-reinforced body members, as well as the coupling nuts, fracture to permit the pole to break away from the foundation. The fiber-reinforced body member of the coupling not only adds hoop strength to the coupling nut, but prevents the metal coupling nut from being exposed to corrosive elements such as salt or the like.
