  • Patent number: 6159111
    Abstract: A portable basketball training device used to teach basketball players how to properly shoot. The training device is comprised of a folding base and a telescoping vertical column supported by the base; attached to the top of the vertical column is a horizontally adjustable u-shaped shooting guide. The training device is used by first unfolding the legs and then adjusting the telescoping vertical column to the appropriate height, which is determined by adjusting the telescoping vertical posts until the bottom of the u-shaped shooting guide is parallel to the wrist of the user's shooting arm with the elbow extended to the shooting position. Once the appropriate height has been set the u-shaped shooting guide is adjusted horizontally in order to prevent horizontal drift of the shooting hand as the ball is projected toward the goal. Proper use of this device also provides optimal arc and natural backspin giving the ball truer flight to the goal.
