Title: Method and apparatus for adjusting a basketball goal
Inventor: NYE STEPHEN F
IPC: A63B63/08
Filed: 1989-02-17
Granted: 1993-02-23
Abstract: ABSTRACT OF THE DISCLOSURE    An apparatus for adjusting the height of a basketball goal.  A basketball goal is pivotally connected to a rigid vertical support by means of two parallel support members thereby forming a parallelogrammatic structure.   A support arm containing a slot with a plurality of notches is pivotally connected to one of the vertexes of the parallelogrammatic structure while the opposite end of the support arm slidably engages a post attached to the parallelogrammatic structure.          The notches are configured such that when a notch engages the post, the parallelogrammatic structure is locked in position.          The method of the present invention allows a user equipped with a pole and standing on the basketball playing surface to apply a  force to the goal thereby forcing the notch to disengage  the  post  and  allowing  the  parallelogrammatic structure to deform such that the user may raise the goal and engage the locking mechanism upon the release of the force.          By applying a force directly to the support arm, a user may disengage the locking mechanism and move the goal to any of several predetermined heights.  When the goal has been placed at the desired height, the force is released thereby engaging the locking mechanism and preventing further deformation of the parallelogrammatic structure.
