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.

What is claimed is: 1. An elevator system for adjusting the height of a basketball backboard above a playing surface, the system comprising: a basketball support element; a basketball backboard having at least a first position above said playing surface and a second position above said playing surf

What is claimed is: 1. An elevator system for adjusting the height of a basketball backboard above a playing surface, the system comprising: a basketball support element; a basketball backboard having at least a first position above said playing surface and a second position above said playing surface, the first position being lower than the second position; at least one elevator arm rotatably connected to said backboard and rotatably connected to said basketball support element; a ratchet having a plurality of ratchet teeth, said ratchet being rigidly connected to said at least one elevator arm; a pawl, said pawl being in engageable relation with the plurality of ratchet teeth when said backboard is at both the first position and the second position and capable of maintaining a position of said backboard above said playing surface; and a cam rotatably connected to said ratchet and said backboard and having an elongated slot, said ratchet being slidably engageable with the elongated slot; wherein the application of an upward force to said backboard when said backboard is at the first position causes said backboard to move to said second position and the application of an upward force to said backboard when said backboard is at the second position causes said cam to disengage said pawl from said ratchet, preventing said pawl from engaging with the plurality of ratchet teeth and permitting said backboard to move from the second position to the first position. 2. The system according to claim 1, wherein: the elongated slot has a first end and a second end; and said ratchet has a pin in slidable engagement with the slot, the pin engaging the first end of the slot when said backboard is located at the first position and the second position and engaging with the second end of the slot during the movement of said backboard from the second position to the first position. 3. The system according to claim 1, further comprising an adjustment pole for applying an upward force to said backboard. 4. The system according to claim 1, wherein the first position is the lowest possible vertical position of said backboard above said playing surface. 5. The system according to claim 1, wherein the second position is the highest possible vertical position of said backboard above said playing surface. 6. The basketball apparatus of the claim 1, wherein said pawl is biased into engageable relation with the plurality of teeth.
