Abstract
An adjustable basketball goal system for adjusting the height of a basketball goal above a playing surface is disclosed. The basketball goal includes a deformable parallelogrammic structure attached at one end to a rigid support. A basketball goal is attached to the other end of the parallelogrammic structure. An adjustment lever is pivotally mounted to the rigid support below the parallelogrammic structure. An extension arm is positioned between the parallelogrammic structure and the adjustment lever such that movement of the adjustment lever deforms the parallelogrammic structure which repositions the basketball goal to a different height above the playing surface. A lockable piston assembly is attached to the rigid support and to the adjustment lever. The piston assembly includes a switch which locks the piston assembly preventing the parallelogrammic structure from deforming. An actuation trigger pivotally connected to the adjustment lever can be engaged to move the switch to an unlocked position thereby allowing the height of the basketball goal to be adjusted. The piston assembly also serves to counterbalance the weight of the basketball goal such that the height of the baske…
