Abstract
Abstract A portable, knockdown football goal post employing a plurality of straight pipe sections to form a U-shaped upright having a cross-bar and a pair of upright members. The U-shaped upright is supported by a pair of vertical support members having their upper ends attached to the cross-bar of the U-shaped upright. Intermediate the ends of the vertical supports is attached an elongated brace member having one end attached to a vertical support, the brace member being parallel to and in the same plane as the cross-bar. The lower end of each vertical support is attached intermediate the ends of an elongated base member, each base member lying in a plane perpendicular to the plane containing the cross-bar and brace member. The uprights, crossbar, vertical support members, brace member and base support members are appropriately water tight. A liquid is placed inside the goal post as a weighting substance.
