A basketball-stand comprising: a base; at least one support system carried by the base; a beam carried by the at least one support system, the beam is attached to a back-board and basketball-rim, the beam-and thereby the stand-being capable of moving between a storage position and a playing position; and gravity operated mechanism acting upon a point connected to the at least one support system and accumulating potential energy when the stand is lowered to the storage position, wherein the accumulated potential energy is released when the stand is raised to the playing position. Preferably, said gravity operated mechanism is at least one weight adjustably suspended from at least one suspension rod, the end of one weight comprising the point connected to the at least one support system, the at least one suspension rod extending substantially horizontally in its position stand, and vertically in its position corresponding to the playing position of the basketball-stand.
