Abstract:

An adjustable basketball goal generally includes a movable support, telescoped within a vertically mounted fixed support, and a hydraulic, water-powered drive mechanism for enabling the raising or lowering of a basketball rim connected to the upper end of the movable support. The drive mechanism includes a dual-compartment water piston and is powered by a conventional garden hose using ordinary household water pressure. With appropriate adjustments made to the water piston, the drive mechanism may be alternatively operable by pneumatic pressure as well as hydraulic pressure. A valve is included for enabling manual control of the drive mechanism. The adjustable basketball goal may also include a rotatable coupling between the movable and fixed supports such that the basketball rim may be rotated 360 degrees about an axis defined by the vertically mounted supports.

The latch bracket having camming edges and being pivotal around said dowel in a past-center relation whereby to cam said camming edges against the second frame member and lock the two vertical frame members together without the use of hand tools. Access from only one side of a panel frame joint is necessary to engage or disengage the interlock system. Only one interlock is required in vertical frame members having at a separate location conventional hook and slot engageable attachments, or equivalent.
