ABSTRACT:
A rollable sports ballast base for supporting a sports apparatus support member comprising a base member which has a first edge and a second edge, a top surface and a bottom surface. The bottom surface is adapted to contact a support surface such as a driveway or other playing surface. There is at least one wheel assembly for contacting the support surface. One of the wheel assemblies is retractable from a lowered position to a raised position such that when in the raised position, the bottom surface of the base member substantially contacts the support surface. In the lowered position, both wheel assemblies contact the support surface thereby separating or elevating the base member from the support surface. In another embodiment, the invention consists of a similar rollable sports base for supporting a sports apparatus support member wherein one wheel assembly is retractable and comprises a pivoting connector coupled to the base member and a wheel bracket coupled to the pivoting connector. The wheel bracket is adapted to receive an axle and at least one wheel, and is further provided with a handle extending outwardly from the wheel bracket. The handle is used to pivotally rotate the wheel assembly about a transverse axis such that when the handle is rotated away from the base member, the wheel contacts the support surface and the bottom surface of the base member is separated or elevated from the support surface.
