A portable wheeled basketball stand has a base which carries at least one support system and a beam for attachment of a backboard and ring. The beam, and thereby the stand, is capable of being moved between a lower, storage, position and a higher, playing position. Power storage springs act between a point connected to the base and a point connected to the at least one support system, and accumulate power when the stand is brought into its storage position. The power is relieved and the accumulated energy in the springs is freed when the stand is brought into its playing position. The base carries rods which are driven downwardly from the base by energy stored in the power storage springs when the beam is brought into its playing position. The rods are connected to a frame for engaging a surface on which the stand is positioned and lift at least a part of the stand from the floor as the stand is brought into its playing position for lifting at least some of the wheels off the surface and thus inhibiting movement of the stand during play.
