Abstract
ABSTRACT
A sports ball has a spherical form and an aerodynamically rough surface.
The ball has a weight in the range 20 to 40 grams. The surface roughness is preferably provided by a layer of woven textile fabric on the outer surface of a spherical core. The ball, when thrown, will simulate and exaggerate the movements of a normal baseball or other simulated ball. The ball may be used as a light weight sports ball or as a training ball for pitchers and batters.

Description
'- 21~9~1 ~PORTS TRAlNING BALL ; `
The present invention relates to sports balls and more particularly to a ball . .. .. ...
that is especially useful for training.
Certain sports involve the throwing of a ba11 to produce desired non-ballistic --ball movements in flight. Such garnes include, for example, baseball, softball and fastball.
-, ~: .., Pitcher training in such a sport is difhcult as a beginning pitcher generally has insufficient j; i control over the ball to produce desired or even detectable ball movements in flight.
The present invention is concerned with a noYel ball that is especially suited for this training purpose. It is to be understood however, that the ba~ has more general ;~
applicability and may be used for training batters or in actual play.
. ",:
According to one aspect of the present invention there is provided a sports ball comprising a subseantially rigid, hollow sphere having a weight in the range ~0 to 40 grams and an aerodynamically rough exterior surface.
The aerodynamically rough surface of the ball is one that will produce significant aerodynamic drag at low ba~ speeds, so that a spinning ba~ ~ snove transversely due to aerodynamic effects as it travels along its flight path. A ball constructed according to the present invention has the ability to produce an exaggerated movement mimtctnng that of 8 normal baseball or other ball when thrown the same way.
The ball~is thus useful both as an instructional tool for the sl~lls of pitching and bat~ng and also as a recleahonal ball.
According to another aspect of the present inven~on there is provided a training ball for training the throwing of a spheAcal sports ball, the training ball having a mass substantially less than that of the sports ball, a surface roughness substantially greater thian that of ~e sports ball and a size substantially e~ual to ~at of the sports ball.

" ,. " .".
~'~, . ..
';'': ~-"' : : .
~,.. , 2102961 ,, It is preferred that the rough surface on the ball is provided by a woven textile fabric covering on the ball core. The covering may be secured to the core by an adhesive or, where desired, by stitching the cover together.
According to a further aspect of the present invention there is provided a method of training the throwing of a spherical sports ball, comprising providing a training ball; providing the tIaining ball with substantially the same size as the SpOItS ba11;
providing the training ball with substantially less mass than the sports ba11; and providing the training ball with a surface that is substantially more aerodynamically rough than the sports ball, and practicing throwing the training ball.
With a training ball emulating a baseball, young children, ages 10 and up can throw pitches which replicate those of professional baseball pitchers. The user can learn the mechanics of various pitches, which can then be transferred to a real baseball once the control of the training ball has been learned. Likewise, a batter may practise hitting balls that move l~e those thrown in a more advanced level of the sport.
The ba11 can be used in a relatively small area, for example a bac~qard or a gymnasium to provide practice year around. The light weight of the ball minimizes any chance of damage occurring through pitching or bat~ng the ball in confined spaces.
In the accompanying drawings, which illustrate exempla~y embodiments of the present invention:
Figure 1 illustrates a ba11 according to the present invention;
Figure 2 illustrates a core of a ball according to the present invention;
Figure 3 illustrates a ball fitted with a simulated baseball cover; and Figure 4 illustrates a cover section for the ball of Figure 3.
Referring to the accompanying drawings, Figure 1 illustraites a ball 10 210 ~ !3 61 constructed according to the present invention. The ball is relatively rigid and has a rough i ~ -outer surface 12 constituted by a layer of woven textile fabric.
Figure 2 illustra~es the core 14 of the ball 10. The core is a hollow plastic ,',~ '"`.,','".'!'.,''.
sphere with holes 16 uniformly distributed over its surface. ~e core has a total mass of 23 grams. To forrn the baU 10, the core is covered with a woven textile fabric as illustrated in Figure 1 bAnging the total mass of the baU up to at least 30 grams. The - ;
circumference of the baU is 23 centimeters. In this embodiment, the textile fabric is secured to the core using an adhesive (not shown). - ~:
An alternative embodiment of the ball is illustrated in Figure 3. This ball 18 - ~

is covered with two strips 20 of textile fabric, one of which is illustrated in Figure 4. As shown in that Figure, each strip has two rounded end lobes 22 and slightly concave side -edges 24 so that the two strips can be wrapped around the ball at right angles to cover the entire ball, in the same way as a baseball is covered. In this case however, the Stlip 20 is , :: ~: . ;.::
made from a woven textile fabric. This technique yields a ball with a searn 26 that is similar in arrangement to that on a conventional basebaU.
.::, ,-. .
The sbips 20 in the iUustrated embodiment are fastened to the baU with an adhesive. In: other embodiments howeverj they may be stitched together in the manner of a baseballco nng.
While certain embodiments of the ball have been illustrated in the foregoing, it is to be understood that other embodiments are possible within the scope of the invention. Thus, for example, it is possiUe to use an uncovered spbere as the ball, ~ ~
provided the mass of the ball is in the 20 to 40 gram range and the surface of the ball is ~ `
aerodynamically rough to create the desired aerodynamic effects on the ball, causing it to ~ :
move transversly in a relatively short flight.

' -' ' ,."',':, 21 02~ 6 1 It is also possible to use covering materials other than a textile fabAc, again providing the aerodynamic roughness of the material is adequate to produce the desired -effectsduringtheball'sflight.
The core of the ball is shown in the foregoing as being a hollow sphere with a number of cireular holes through the waU of the sphere. The core may be made in other ways. It may, for example, omit the holes and it may be other than hoUow, if the weight of the baU does not exceed the desired maximum.
