发明名称 Cue ball point of aim training device and method of use
摘要 A cue ball point of aim training device, comprising a target, a target positioning member, a transverse member, and a support structure provided for aiming a cue ball with respect to a given object ball. The base of the support structure, when positioned on the playing surface, resides to one side of a line bisecting the object ball along the desired direction of travel, and can remain in place during a shot on the object ball. The target, representing where the center of a cue ball needs to be to effectuate a desired trajectory for a given object ball, is positioned by the other components of the device in an opposite direction along the line of intended travel of the object ball. Through repeated use in practice, the cue ball point of aim training device may aid in improving one's skill in playing the game of billiards.
