Abstract: A portable basketball assembly is provided which can be readily collapsed into a lowered position permitting storage of the assembly in a conventional garage; in addition, the assembly can be wheeled to a desired location and elevated through a single winch cable to a regulation playing height. In preferred forms, the assembly includes a vertically shiftable, telescopic, backboard-supporting frame as well as structure for raising and lowering of the backboard relative to the frame. In this fashion, the overall assembly can assume a very low profile for storage purposes, whereas raising the backboard for playing is readily accomplished. The assembly can also be elevated to an intermediate playing position below regulation height to accommodate younger players, and an elongated brace secured to the backboard and engageable with the assembly base or frame is provided in order to stabilize the unit at all positions of the backboard.
