Abstract: An anchor for anchoring the post of a basketball goal to a container. The anchor includes a portion of a vehicle tire that has been modified so that the tire has been severed transversely to provide a pair of ends and a major portion of the sidewalls of the tire have been removed to provide partial sidewalls respectively having holes therethrough adapted to receive the post of a basketball goal. A tightener extends between the pair of ends for selectively drawing the ends together to tighten the anchor around a container. A modified embodiment includes a tire of a right size to snugly fit around a container or a portion thereof and the tire is complete except for aligned holes respectively in the opposite sidewalls of the tire and adapted to receive the post of a basketball goal. A specially designed container is disclosed that is adapted to be used with the modified embodiment.

Abstract: A portable basketball goal assembly which includes an anchor, a goal post, a backboard, and a basket. The mass of the anchor is variable to promote mobility. The anchor includes a nonpermeable receptacle which facilitates the storage of a volume of substance, such as water. The container may be either a drum, such as an industrial drum, a rain barrel, a garbage canister, or the like, or it may be an industrial strength bag suspended from a frame assembly both of which are capable of retaining the volume of substance. The volume of substance is proportional to the mass of the anchor. A variance in the volume of substance produces a variance in the mass of the anchor. The nonpermeable receptacle has an opening in the top to allow the user to add to the volume of substance, thus increasing the mass of the anchor. Also included near the bottom of the nonpermeable receptacle is a stopclock which enables the user to discharge some of the volume thereby decreasing the mass of the anchor.
