ABSTRACT:
A basketball goal for mounting on a backboard for providing absorption and dissipation of the energy occuring during a dunk shot or the like. The rim of the goal is pivotally mounted to the backboard and held in place by means of a spring and fluid filled hydraulic piston-cylinder mechanism which are mounted between the backboard and the rim. A downward force on the rim is opposed primarily by a vertical coil spring surrounding the cylinder. The cylinder and spring are coaxial with the axis being substantially parallel to the plane of the backboard. The downward motion of the rim opens a valve in the piston-cylinder allowing the cylinder to be moved upwardly with the downward movement of the rim with substantially no hydraulic restrictions. When the rim begins its return to normal position under spring pressure, the valve is closed. The piston has a predetermined diameter smaller than the inside diameter of the cylinder. Expansion of the compressed spring forces the piston upwardly, with the space between the piston wall and cylinder wall creating a limited flow of the fluid so as to cushion and dampen the return of the rim to its normal position.
