Abstract
A softball pitching aid enables one to practice throwing rise balls and drop balls at slower speeds than that required by a standard softball. It comprises a ball with opposing convex surfaces at either end of and disposed about a central axis and a plurality of symmetrical slots protruding into its outer surface and disposed circumferentially along the central axis. The ball is constructed of polyurethane foam or other lightweight material. When thrown correctly, the slots interact with ambient air to cause the ball to rise or drop. The slots and lightweight material allow the ball to rise or drop at lower speeds. The slots further provide guidance for gripping the ball and leverage for increasing its spin rate during flight. The ball further comprises a two-tone coloring scheme that, in conjunction with the symmetrical slots, provides instant visual feedback during flight as to whether it was thrown correctly.

DETAILED DESCRIPTION OF THE INVENTION
(7) The invention described herein is a softball pitching aid to be used to practice throwing rise balls and drop balls in fast pitch softball. The apparatus is a lightweight ball comprising a plurality of symmetrical slots that, when the ball is thrown, mimic the interaction between the seams of a softball and the ambient air in exaggerated fashion, enabling one to throw rise balls and drop balls at slower speeds and to practice their delivery for doing so with instant visual feedback. The slots further guide the user to position his or her hand correctly on the ball and also provide a means for the user to exert additional pressure on the ball to increase spin speed.
(8) Referring to
(9) Each slot 120 comprises a base 121, opposing walls 122, 123, and opposing ends 124, 125. The slots 120 are of the same size and shape and spaced uniformly about the circumference of the ball 100. The base 121 of each slot 120 further comprises a pair of adjoining convex bands 126, 127 that run circumferentially along the central axis X of the ball 100—from one end of the slot 120 to the other—and alongside one another. The bands 126, 127 are angled inwardly toward one another, such that their shared boundary 128 creates an indentation along the centerline of the slot 120.
(10) The sides 129, 130 of the bands 126, 127 opposite their shared boundary 128 adjoin the bases of the opposing walls 122, 123 defining the slot. The opposing walls 122, 123, in turn, mirror one another and slope outwardly and away from one another in substantially linear fashion, from the base 121 of the slot 120 to the outer surface 101 of the ball 100.
(11) Each slot 120 is further defined by opposing ends 124, 125 that connect the base 121 of the slot 120 to the convex surfaces 110, 111. The opposing ends 124, 125 mirror one another and connect the base 121 of the slot 120 to the convex surfaces 110, 111.
