ABSTRACT:
Basketball goal height adjustment apparatus comprising a three dimensional parallelogram having nominally parallel but adjustable parallelogram bars. A mounting member is secured to the rear surface of the basketball backboard and coupled to a frame to which the parallelogram bars are also attached. A notched bracket member is secured to the mounting member and a bifurcated member, one end of the bifurcated member including a spring loaded pin which is operatively biased into engagement with a selected one of said notches, each notch corresponding to a predetermined vertical height of the goal. A device for visually indicating the height of the goal is also provided. To adjust the goal height, the bifurcated member (or the backboard) is pushed such that the pin moves away from the notch. The backboard is then moved to the desired height at which time the force is removed from the bifurcated member, the pin being positioned by the compressive force of the spring into the notch corresponding to the desired goal height.
