SPORTS BALL, BAT, AND ASSOCIATED METHODS

Abstract

A sports ball for use in baseball-type games includes a hollow, substantially spherical plastic ball that has a plurality of substantially planar, intersecting regions covering an outer surface thereof. Preferably the ball also has a weight that is substantially less than a weight of a regulation baseball, for enhancing safety in use. The sports system further includes a bat for use with the ball, or with any similar ball, preferably a plastic ball. The bat is a hollow, elongated member that has a handle portion adjacent a bottom end and a barrel portion between the handle portion and a top end. The bat further has a sheath surrounding at least a portion of the barrel portion. The sheath has a coefficient of friction higher than a coefficient of friction of a surface of the barrel portion, for imparting traction to a struck ball.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0019] Referring to FIGS. 1 and 2, the present invention is directed to a sports system that comprises a sports ball 10 for use in baseball-type games. The sports ball 10 comprises a hollow, substantially spherical ball. The ball 10 may comprise a plastic material, although this is not intended as a limitation.

[0020] The ball 10 has a plurality of substantially planar, intersecting regions 11 covering an outer surface 12 thereof. In some embodiments the regions 11 may be slightly concave or convex without departing from the spirit of the invention. The regions 11 may be either regular or irregular, and do not have to conform to a specific pattern. Also preferably the ball 10 comprises a sufficient number of planar regions 11 to remain substantially spherical, meaning that the ball 10 will still bounce and rebound in a manner similar to a spherical ball, such that the bounce and rebound are predictable upon striking subsequent contact with another surface.

[0021] Through experimentation, it has been found that the ball 10 of the present invention travels faster and farther than similar products, and also curves more. However, the aerodynamic characteristics are closer to those of a regulation baseball than to a Wiffle ball, in that baseball spins can be imparted. Since the ball 10 is lighter, safety is enhanced, and also the ball 10 curves much more than a regulation baseball without having to be thrown as hard. In fact, with sufficient backspin, the ball 10 can rise in flight.

[0022] Another advantage is that the planar regions 11 allow for a better grip, also enhancing the amount of spin that can be imparted. Preferably the ball 10 also has a weight that is substantially less than a weight of a regulation baseball, for enhancing safety in use.

[0023] Referring to FIG. 3, the sports system of the present invention further includes a bat 20 for use with the above-described ball 10. The bat 20 comprises an elongated, hollow, lightweight element having a standard bat shape, including a handle portion 21 and a barrel (hitting) portion 22. In a particular embodiment, at least part of the barrel portion 22 is surrounded by a striking sector comprising a sheath 23 that imparts greater traction to a ball 10 when hit than other known bat surfaces. The sheath 23 has a coefficient of friction greater than an adjacent surface sector 24. Alternately, the striking sector can be built or molded into the bat. In either case, it is preferred that the striking sector 23 have a more resilient surface than the adjacent surface sector 24. In a preferred embodiment, the sheath 23 comprises a rubber material, although this is not intended as a limitation.

[0024] The bat 20 of the present invention is usable with other balls besides that 10 of the present invention, and confers cost, safety, and usage advantages over other bats of the prior art. For example, plastic balls travel farther when struck with the bat 20, because of increased backspin created when the ball is properly struck. The hitting surface 23 of the bat 20 provides traction between the ball 10 and the bat 20 and grips the ball 10 at the point of impact to spin the ball at a higher rate than do other known plastic bats. Such backspin created from a properly hit ball creates loft, which carries a ball a greater distance.

[0025] In addition, there is a synergy between the ball 10 and the bat 20 of the present invention, wherein the intersections 13 between planar regions 11 can be gripped effectively by the striking sector 23.

[0026] Even if a ball is struck in a non-ideal manner, the sheath 23 still grips the ball better, resulting in a more efficient transfer of force between the ball and bat 20. If a typical plastic baseball is not hit at its exact center, a portion of the bat's force is lost on the ball owing to slippage, particularly when a plastic ball is struck by a plastic bat surface, thereby resulting in lazy fly balls or weak ground balls. The bat 20 of the present invention, however, preserves some of the force that would otherwise have been lost, and allows the batter to hit the ball harder even if the ball is not struck at an ideal angle.

[0027] The bat 20 also delivers a longer ball because of its added weight over known plastic bats. Additionally, the bat 20 of the present invention is advantageous because the striking sector 23 serves to protect the batter's hands by acting as a shock absorber if a ball is not struck in an ideal manner.

[0028] Referring to FIGS. 4 and 5, according to another embodiment of the present invention, a ball 110 has a plurality of planar regions 111 forming an outer surface 112 thereof. Preferably, the ball 110, like the ball 10, is substantially hollow. Preferably, there are 72 planar regions 111, including 60 hexagonal regions 111A and 12 pentagonal regions 111B. A raised seam 113 extends generally around a circumference of the ball 110 between borders of a portion of the planar regions 111.

[0029] According to a further embodiment of the present invention, referring to FIG. 6, a ball 210 has a plurality of planar regions 211 forming an outer surface 212 thereof. Preferably, the ball 210, like the balls 10 and 110, is substantially hollow. As with the ball 110, there are preferably 72 planar regions 211, including 60 hexagonal regions 211A and 12 pentagonal regions 211B. A raised seam 213 extends generally around a circumference of the ball 210 between borders of a portion of the planar regions 211. A plurality of concave divots 214 are formed in the outer surface 212. Preferably, one divot 214 is generally centered in each of the planar regions 211. The depicted divot 214 is generally circular, although the present invention is not necessarily limited to a particular divot shape.

[0030] For instance, according to an additional embodiment of the present invention, referring to FIG. 7, a ball 310 has a plurality of planar regions 311 forming an outer surface 312 thereof. Preferably, the ball 310, like the balls 10, 110, and 210, is substantially hollow. As with the balls 110 and 210, there are preferably 72 planar regions 311, including 60 hexagonal regions 311A and 12 pentagonal regions 311B. A raised seam 313 extends generally around a circumference of the ball 310 between borders of a portion of the planar regions 311. A plurality of concave divots 314 are formed in the outer surface 312. The shape of the divots 314 generally corresponds to the shape of the planar regions 311 in which they are formed. For example, hexagonal divots 314A are formed in the hexagonal regions 311A and pentagonal divots 314B are formed in the pentagonal regions 311B.

[0031] In the depicted embodiment, one divot 314 is generally centered in each of the planar regions 311. Alternately, divots could be selectively omitted from some planar regions 311. For example, divots could be omitted from some or all of the pentagonal regions 311B. Additionally, the divots could be made larger or smaller. For example, each divot could extend almost to the intersections with adjacent regions. Divots could also be located off center and/or extend onto more than one planar region.

[0032] Unlike the divots 214, which have a slopping transition from their respective regions 211, the divots 314 have a stepped transition from their respective regions 311, although the present invention is not necessarily limited to a particular transition type.

Moreover, the embodiments of the apparatus illustrated and described herein are by way of example, and the scope of the invention is not limited to the exact details of construction.
