Abstract
A training ball having substantially the same size, and exterior construction and appearance as a regulation ball, but having a lighter weight than a regulation ball. The training ball is deformable upon contact with the fielder. The training ball includes an outer shell filled with a particulate material such as polypropylene beads, resulting in a ball having a lower coefficient of restitution than a regulation ball.
Claims
exact text as granted — not AI-modified1 . A training ball having an exterior shell of substantially the same size, construction and appearance as a corresponding regulation ball, but having a lighter weight than a regulation ball.
2 . The training ball of claim 1 , wherein the corresponding regulation ball is a baseball, and the exterior shell of the training ball has a generally spherical shape with a diameter of between about 2¾″ to 3″, and a weight of between about 3½ ounces to about 4½ ounces.
3 . The training ball of claim 2 , having a weight of between about 4.0 ounces to about 4.25 ounces.
4 . The training ball of claim 1 , wherein the exterior shell is constructed of two panels of white leather joined by red stitching.
5 . The training ball of claim 1 , wherein the exterior shell is substantially filled with beads.
6 . The training ball of claim 5 , wherein the beads are formed of polypropylene.
7 . The training ball of claim 5 , wherein the beads have a diameter of between about 0.1 to 0.2 inches.
8 . The training ball of claim 5 , wherein the beads are enclosed within an inner shell, which is enclosed within the exterior shell.
9 . The training ball of claim 1 , having a substantially reduced coefficient of restitution relative to the corresponding regulation ball.
10 . A training ball having an exterior shell of substantially the same size, construction and appearance as a corresponding regulation ball, but being substantially more deformable than the regulation ball.
11 . The training ball of claim 10 , wherein the outer shell is filled with a particulate material.
12 . The training ball of claim 11 , wherein the particulate material comprises polypropylene beads.
13 . The training ball of claim 11 , wherein the particulate material comprises beads having a diameter of between about 0.1 to 0.2 inches.
14 . The training ball of claim 10 , having a lower weight than the corresponding regulation ball.
15 . The training ball of claim 14 , wherein the corresponding regulation ball is a baseball, and wherein the training ball has a weight of between about 4.0 ounces to about 4.25 ounces.
16 . The training ball of claim 10 , wherein the exterior shell is constructed of two panels of white leather joined by red stitching.
17 . A method of practicing play with a regulation ball, said method comprising delivering the ball of claim 10 to a player.
18 . The method of claim 17 , wherein the player is a fielder, and the method further comprises contacting the delivered training ball with a fielding glove of the player.
19 . The method of claim 17 , wherein the player is a batter, and the method further comprises contacting the delivered training ball with a bat.
20 . A game comprising the steps of:
a) forming teams of five players; b) positioning each of the five players of a defensive team as infielders in a position selected from first baseman, second baseman, shortstop, third baseman and pitcher positions; c) designating one of the five players of an offensive team as catcher; d) setting base-path lengths based on an average ability level of the players; e) commencing play following standard rules of baseball, with the following exceptions:
i. each batter begins with a count of one ball and one strike and the batting team begins its inning with one out;
ii. a coach or a member of the batting team pitches the ball;
iii. any ball that rolls past the infield is an automatic double with the batter advancing to second base;
iv. any ball that goes over the head of the infielders on the fly is considered an automatic home run;
v. offensive players do not advance on an overthrow of any base.Join the waitlist — get patent alerts
