Problems solved by technology

However, the release of the pawl usually requires precise and difficult positioning of the end of the rod on the pawl, which is located on the underside or behind the backboard
Since the detents present small targets, positioning of this bar can be particularly difficult, and the situation can be made worse when the backboard is in its highest position
[0007] Also, for some individuals, such as small children, trying to position the bar to both release the detent and lower the height of the backboard can be very difficult
As a result, some individuals may be discouraged from changing the height of the backboard due to the difficulty in precisely releasing the detents

Embodiment Construction

[0020] The present disclosure will now be described more fully with reference to the accompanying drawings, in which various embodiments of the invention are shown. However, the disclosed subject matter may be embodied in many different forms and should not be construed as limited to the embodiments described herein.

[0021] Figure 1 illustrates an adjustable basketball hoop system 100 in accordance with an embodiment of the present invention. The basketball hoop system 100 may include a rigid support rod 120 extending from the base 110 in a generally upward direction. Although the embodiment in FIG. 1 shows the use of a movable base 110, the system can also be used where the basketball support pole 120 is fixed relative to a playing surface (not shown). While playing surface will be considered generally to mean ground, it is also contemplated that basketball support pole 120 may be fixed in concrete, the type of indoor ground found in gymnasiums, asphalt, or any basketball ...

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.

Description

field of invention [0001] The present invention relates to apparatus and methods for adjusting the height of a basketball backboard assembly. Background of the invention [0002] Basketball has become an increasingly widespread sport, and backyard and neighborhood basketball hoops are becoming more common. These backyard basketball goals are often used well for families and groups playing sports with a wide variety of people, including adults and children. Accordingly, height-adjustable basketball hoops have become the most popular products in backyards or on private basketball courts because they allow individuals of different heights and skill levels to play on the same basketball hoop. [0003] A number of adjustable height basketball hoops have been proposed for accomplishing incremental adjustments in the vertical height of a basketball backboard assembly. Such devices are often incorporated into a parallelogram-type support frame that allows vertical movement of the ...
