Abstract
The present invention is related to a system and method for adjusting the height of a basketball backboard assembly. The present invention includes a releasable locking mechanism connected to the backboard assembly to lock the backboard at a selected vertical height above a playing surface. In one embodiment of the present invention, the releasable locking mechanism may include a ratchet and cam, the ratchet having a plurality of ratchet teeth configured to engage with a pawl. A cam may be configured to allow a user to incrementally increase the height of the backboard using the releasable locking mechanism and may further be configured to prevent the releasable locking mechanism locking the backboard at any height when a user desires to decrease the height of the backboard.
