摘要： A portable sports field goal assembly and framework includes an elongated net with a peripheral rope frame that may be secured to portable end frames. The end frames are made up of at least two releasably interconnected support members that can be secured in upright positions along the ground surface by ground cup assemblies and by guy cord assemblies. Lengths of the rope frame may extend through openings along the support assemblies. The rope lengths are knotted to secure the net corners to the frames. The ground cup assemblies each include an upwardly open cup with a central opening in its bottom horizontal wall. The openings receive headed spikes that may be driven into the ground to secure the cup against the ground surface. The cups also include access openings that receive lengths of the rope frame to be looped over the headed ends of the spikes. The rope frame can thereby be secured by the spikes to the ground and the supporting general framework.
