Abstract
Markings are added to the conventional solid color racquetball ball, which gives the player additional information on the likely trajectory of the ball, and the player is thus able to make a more precise return stroke. When a ball is marked in some visible manner, the player is better able to judge the rotation caused by the walls of the racquetball court, and can adjust his stroke or swing to improve the accuracy of the return. In racquetball the rotation of the ball is particularly important because many shots are received after having bounced off one, two, or three walls, and the rotations are thus difficult to predict. In racquetball the conventional ball is a solid color and the rotation of the ball is not discernible to the player's eye. The markings introduced by this invention make the wall-induced rotation more discernible.
Description
- For the game of racquetball, readily visible markings are added to the racquetball. The markings are in the form of stripes or dots or in the form of colored quadrants. Without markings, a player cannot discern the rotation of the ball. With markings, the rotation of the ball is discernible. In racquetball, many unusual bounces occur, from multiple walls, and from the floor, causing a multiple varieties of rotation and unexpected bounces. A teacher can explain these rotations if there is the aid of markings. The rotations cause multiple directions to be taken by the ball as it leaves the floor. A coach is better able to call to the attention of the student how a ball is set to rotating by striking a wall, and causing unexpected directions of bounces from another wall or from the floor. The markings on the ball area visible to the layer and the coach, and thus the player can better estimate the likely trajectory of the ball after bouncing off the wall or floor. The precision and accuracy of the return shot is improved, and the players receive more satisfaction from the game. The marking principle may also be applied to the ball used in the game of handball. Note: This application is substantially a resubmission 09/199,210.

The return stroke is made after the ball leaves one of the walls. With a solid colored ball, the eye receives no information on rotation.

Watching the stripes as well as the ball, the player is able to more accurately predict the trajectory as it leaves the wall, and so makes a better and improved return shot.

- There is further prior art shown in the patent application of Nov. 24, 1998, Ser. No. 09/199,210, which was an effort to patent a ball for racquetball. The application was abandoned in approximately 2001, and is now reinstated. The reinstatement is owing to the markings having been found particularly suited for racquetball training purposes. The examiner for 09/199,210 is thanked for having found pertinent prior art.
