ABSTRACT:
Certain preferred embodiments of the present invention provide an improved adjustment system and method for raising and lowering a basketball backboard and goal using a telescoping assembly such as an extension and retraction cylinder. In some preferred embodiments, an actuator assembly is mounted to a midpoint of a lever arm and situated such that the extension or retraction of the actuator assembly causes a mechanically advantaged travel in the height adjustment structure for the goal assembly. As a preferred feature, the present invention provides a greater height adjustment distance in the backboard assembly for a reduced number of cranks compared to a direct connection between an actuator incorporated in or directly attached to an adjustment arm.
