Problems solved by technology

The pitching techniques used to curve this ball differ from that of pitching techniques used to curve a conventional baseball; therefore this ball does not make a practical pitch training aid.

Embodiment Construction

[0025] With reference to the drawings, and in particular to FIGS. 1-10 thereof, a baseball embodying the principles and concepts of the present invention will be discussed.

[0026]FIG. 1 illustrates a perspective view of baseball 10 made according to a preferred embodiment of the present invention. The baseball comprises a core body member 20 and a plurality of V-shaped vent member sections 40 which follow a lined figure-8 path around the ball's surface, basically in the same manner as that of the stitching of a conventional baseball. Fin member 41 of vent member section 40, (see in particular FIG. 8) acts as an air deflecting shield which increases the drag forces against the ball as it is thrown through the air with a rotating spin motion, causing the ball to curve more dramatically. Cross braces 42 help support center fin member 41 and also provide an outer surface 43, filling the gap between fin member 41 and core body member 20, essentially forming a continuation of the outer pe...

Abstract

An instructional baseball used for the art of teaching the proper techniques of throwing a curveball is shown having a spherical body with a recessed elongated V-shaped groove which extends around the outer surface of the body in a figure-8 path similar to the stitching of a conventional baseball. Centered within the V-shaped groove opening is a fin member which also follows the same figure-8 path as the V-groove. The fin member acts as an air shield creating greater drag forces on the baseball as it is thrown through the air with a spinning motion. The greater drag forces increase the Magnus force on the ball, allowing it to curve move dramatically then that of a conventional baseball. Increasing the curve rate of the baseball will serve to help pitchers more easily see the results of their throwing techniques and ultimately improve their curveball throwing skills. To fill the gap left on each side of the fin member and give the pitcher a surface to grasp, cross braces are set perpendicular to the fin member and are spaced evenly along the figure-8 path of the groove and fin member.

Description

FIELD OF THE INVENTION [0001] This invention relates to a baseball, and more particularly, to an instructional baseball which is designed to curve more dramatically when thrown than that of a conventional baseball. The instructional baseball is intended to help pitchers learn the art of throwing curveballs. Generally, according to the principle behind throwing a curveball, as the ball travels through the air in a spinning motion, the side which is spinning toward the direction of travel is traveling at a greater speed than the side which is spinning away from the direction of travel and therefore, the side which is traveling at a higher speed has more drag forces applied to it, creating a Magnus force which moves the ball in a side, curving direction. This invention is intended to increase the drag forces on the spinning baseball creating a larger Magnus force which results in improved curving action compared to conventional baseballs. With conventional baseballs, the general surfac...
