In sports, round athletic balls typically spin or rotate when being thrown, kicked, hit, rolled or otherwise projected a particular distance. A rotation is a circular movement of a ball around its center of rotation. Balls and spheres rotate around an imaginary line called a rotation axis. When an athletic ball such as a baseball travels through the atmosphere, the baseball experiences the force of gravity in addition to the drag and Magnus forces as understood by the skilled artisan. For example, when a baseball pitcher throws a baseball, the forward movement of the pitcher's arm propels the baseball with a force that produces a velocity. A countering force called drag (air resistance) slows the baseball down. Simultaneously, the force of gravity places a downward motion onto the baseball. When a ball spins, it creates an envelope of air around it called the boundary layer. This boundary layer moves with the ball whether it spins forward or backward or sideways. The interaction of this boundary layer with the surrounding air results in an outside force that changes the path of the baseball. As understood by persons of ordinary skill in the art, this is known as the “Magnus Effect.”
The spin of the baseball dictates the rotation of the boundary layer. When the ball has back-spin, like a fastball, the boundary layer under the baseball shoots air forward into the air that is trying to move around the baseball. The opposing air flows result in slower air movement and higher air pressure underneath the baseball. On top of the ball, the boundary layer shoots air backward in the same direction as the air that is trying to move around the baseball. These air flows compliment each other and combine to create faster air movement and lower air pressure on top of the baseball. The combination of slower air movement under the ball and faster air movement over the ball creates lift that opposes gravity—a “rise.” The Magnus Effect, in this case, acts just like an airplane wing. For a curveball, the top-spin is like turning that wing upside-down. The opposing air flows are now on top of the baseball and the complimentary air flows are on bottom. Here, the Magnus Effect creates lift that compliments gravity—a drop. With a tilted spin axis, the Magnus Effect creates a tilted lift. A left tilt adds right-to-left movement when the pitch has back-spin and left-to-right movement when the pitch has top-spin. A right tilt has the opposite effects. When a pitch spins perfectly sideways, like a screwball or a sweeping curveball, the Magnus Effect does not create a “rise” or drop. Instead, it creates sideways lift. Viewed from the top, clockwise spin results in left-to-right lift, and counter-clockwise spin results in right-to-left lift. The Magnus Effect is greatest when the baseball's rotation axis is perfectly perpendicular to the velocity of the baseball. As the rotation axis turns (or yaws) from perpendicular to parallel to the baseball's velocity, the Magnus effect decreases accordingly. Likewise, the magnitude of the Magnus effect increases as the spin axis moves from parallel to perpendicular to the baseball's velocity.
In sports, to achieve a desired path of travel of a ball in space it is often necessary to produce a particular ball rotation. Likewise, a particular ball rotation is often an indicator that a ball has been thrown, kicked, tossed, hit, etc., in a proper manner, otherwise a particular rotation would not have been achieved. For example, a properly shot basketball released from a person's hand should have a substantially true backspin, i.e., true north to true south of the ball, toward the basketball goal. By providing a training tool with an indicator member that is visible to the user and/or another person and/or a coach the rotation of a particular ball may be evaluated to determine its accuracy in regard to the optimum desired ball rotation for a particular activity in question.
To better understand the novelty of the device, assembly, system and method of use thereof, reference is hereafter made to the accompanying drawings. Generally, one simplified training tool of this application is provided in
With reference now to
In one embodiment, the training tool 10 may be manufactured to include a ball 12 and indicator 14 in combination as desired. In another embodiment, the training tool 10 may be constructed using a preexisting ball 12 whereby an indicator 14 may be attached thereto. In one suitable embodiment of original manufacture, a training tool 10 may include an indicator 14 adhered directly to the outer surface of the ball 12. In another embodiment of original manufacture, the proximal end of an indicator 14 may be set below the surface of the ball 12 to a desired depth, e.g., a depth that substantially maintains the center of gravity of a particular ball 12 with the addition of a particular indicator 14.
Depending on the type of ball 12 in question, the ball 12 may be provided with a cavity or hole for receiving part of the indicator 14 in a mating position thereto. In one embodiment, the indicator 14 may be adhered to the inner surface of the cavity or hole using one or more adhesives. In another embodiment, an indicator 14 may be threadedly connected to the ball 12. In another embodiment, the indicator 14 may be attached to a ball 12 using a snap-fit type connection. In embodiments comprising threaded and snap-fit type connections, the indicator 14 may be removable as desired, e.g., in order to replace the indicator 14 or to provide a ball 12 less the indicator 14 for one or more purposes. Without limiting the invention, suitable adhesives include, but are not necessarily limited to thermosetting or thermoplastic adhesives, expanding glues, radiation cured adhesives, adhesives activated by solvents, and combinations thereof.
In other embodiments, a ball 12 for a particular sport may be acquired and there after converted into a training tool 10. For example, a regulation baseball 12 may be converted to a training tool 10 by adhering an indicator to the outer surface of the baseball 12. In another embodiment, an internal cavity or hole 20 may be formed into the baseball 12 for receiving at least part of an indicator 14 therein (see
In another embodiment, the indicator 14 may be operationally configured to receive a secondary indicator in attachment thereto. As seen in the simplified embodiment of
Without limiting the invention, a suitable indicator 14 has a length ranging from about the surface of the corresponding ball 12 out to a length greater than the outer diameter (or width) of the corresponding ball 12. Likewise, a suitable indicator 14 has a width (or outer diameter) up to about equal the outer diameter (or width) of the corresponding ball 12. In one particular embodiment, the length and width of the indicator 14, relative to the corresponding ball 12, is a size operationally effective to allow for use of the training tool 10 without disrupting the ball's 12 performance as accomplished with a stand alone ball 12. As an example, in an embodiment where the training tool 10 includes a baseball/softball 12 type device, a suitable indicator 14 has a size that does not affect a person's ability to catch the training tool 10 in a baseball/softball glove or mitt. In an embodiment where the training tool 10 includes a basketball 12 type device, a suitable indicator 14 has a size that allows for the training tool 10 to pass through a basketball goal (hoop and net). In addition, a suitable indicator 14 is attached to a ball 12 in a manner not affecting the center of gravity of the ball 12 thereby maintaining a true and correct spin in a substantially similar manner as a stand alone ball 12.
In an embodiment of a training tool 10 including a regulation baseball 12, a suitable indicator 14 has a visible length extending from the surface of the baseball 12 ranging from about 3.18 mm to about 50.8 mm (about 0.125 inches to about 2.0 inches) and a width ranging from about 3.18 mm to about 19.05 mm (about 0.125 inches to about 0.75 inches). In one suitable embodiment of a baseball type training tool 10, the visible length of the indicator 14 may be up to about 50.0 percent the outer diameter of the baseball 12, i.e., a ratio of about 1:2. In another suitable embodiment of a baseball type training tool 10, the width of the indicator 14 may be up to about 10.0 percent the outer diameter of the baseball 12, i.e., a ratio of about 1:10. As stated above, the length of the indicator 14 housed within a ball 12 may vary as necessary to substantially maintain the center of gravity of the ball 12. In terms of a regulation baseball 12, an indicator 14 may include a total length from about 6.35 mm to about 108.0 mm (about 0.25 inches to about 4.25 inches).
In an embodiment of a training tool 10 including a regulation softball 12, a suitable indicator 14 has a visible length extending from the surface of the softball 12 ranging from about 3.18 mm to about 57.15 mm (about 0.125 inches to about 2.25 inches) and a width ranging from about 3.18 mm to about 19.05 mm (about 0.125 inches to about 0.75 inches). In one suitable embodiment of a softball type training tool 10, the length of the indicator 14 may be up to about 40.0 percent the outer diameter of the softball 12, i.e., a ratio of about 2:5. In another suitable embodiment of a softball type training tool 10, the width of the indicator 14 may be up to about 6.5 percent the outer diameter of the softball 12, i.e., a ratio of about 3:50. In terms of a regulation softball 12, an indicator 14 may include a total length from about 6.35 mm to about 146.1 mm (about 0.25 inches to about 5.75 inches).
Regardless the intended use of a particular training tool 10, a suitable indicator 14 is constructed from one or more resilient materials resistant to chipping, cracking and reshaping as a result of ozone, weathering, heat, moisture, other outside mechanical and chemical influences, as well as various impacts and other loads placed on the indicator 14. Suitable materials include resilient type materials (at least in part) operationally configured to be displaced from an original unstressed position (“P-1”) to a stressed position (“P-2”) and return to the unstressed position once an applied force is removed from the indicator 14 (see for example the simplified illustration in
In one suitable embodiment, an indicator 14 may be constructed from a one-piece or solid resilient rubber or plastic material operationally configured to act as shown in
In another suitable embodiment, an indicator 14 may be constructed from two or more component parts as desired. For example, the indicator 14 may include a rubber member with a resilient member disposed longitudinally therein. Without limiting the invention, one suitable resilient member includes a resilient coil spring operationally configured to be manipulated, e.g., stretched and/or compressed, and return there after to its original unstressed position, e.g., position P-1. Although the training tool 10 may be built to scale, a suitable resilient member includes a length up to about 95.0 percent the length of the corresponding rubber member of the indicator 14. In an embodiment for use with baseball and softball, a suitable resilient member includes a length of about 6.35 mm (0.25 inches) less than the total length of the corresponding rubber member of the indicator 14. In operation, the proximal end of the resilient member is set about flush with the proximal end of the rubber member set inside the ball 12, i.e., the distal end of the resilient member is about 6.35 mm (0.25 inches) shorter than the distal end of the rubber member. Without limiting the invention to a particular embodiment or mode of operation, one suitable resilient member for use with a baseball or softball type indicator 14 may be provided as follows:
Without limiting the invention, a training tool 10 of this application may include a weight up to about 15.0 percent greater than a corresponding stand alone athletic ball 12. For example, a baseball related training tool 10 may weigh from about 5.0 to about 11.0 percent greater than a regulation baseball 12. A softball related training tool 10 may weigh from about 5.0 to about 16.0 percent greater than a regulation softball. In addition, an indicator 14 may include a weight from about 0.1 percent to about 20.0 percent the weight of a corresponding stand alone athletic ball 12.
It is further contemplated that an indicator 14 of this application may include one or more colors as desired. For example, the indicator 14 may include a bright color such as orange or red. In another embodiment, the indicator 14 may include a fluorescent color including, but not necessarily limited to fluorescent orange, yellow, and combinations thereof. The second indicators 16 may also include one or more colors as desired. For example, a baseball related training tool 10 as shown in
As stated above, to achieve a desired path of travel of a ball 12 in space it is often necessary to produce a particular ball rotation. Likewise, a particular ball rotation is often an indicator that a ball has been thrown, kicked, tossed, hit, etc., in a proper manner, otherwise a particular rotation would not have been achieved. In the sports of baseball and softball, pitchers typically cause a ball 12 to rotate in a particular manner (or not to rotate when throwing a knuckle ball as the term is understood by the skilled artisan) in an attempt to cause the ball 12 to travel along a particular path in space from the point of release of a ball 12 from the pitcher's throwing hand to a catcher set up behind home plate. As understood by persons of ordinary skill in the art of pitching, the manner in which a baseball or softball is gripped (see the simplified examples of
Turning now to a softball related training tool 10, exemplary grips and the rotation/spin of several pitches in slow and fast pitch softball will be discussed. Generally, the act of delivering a softball pitch includes a number of steps or phases, including (1) the preparation phase, (2) the cocking phase, (3) the arm acceleration phase and (4) the follow through phase. Pitching is a complex movement involving the lower body, the body core, upper body, and upper extremities through the various phases listed above. Like baseball, softball also includes a plurality of pitch types and travel paths, some of which are depicted in
Turning to
Various softball pitch types and the grip of each in relation to the training tool 10, indicia 16 thereon and position of the indicator are illustrated in
Various softball pitch rotations in space are shown in relation to the training tool 10 in
One advantage of the present training tool 10 includes that once a person has trained with the tool 10, the person may be subsequently given a regulation softball, whereby the person is likely to throw it according to the grip, rotation/spin and mechanics as utilized with the training tool 10. Thus, the training tool 10 may be employed for developing desired muscle memory for one or more throwing motions according to one or more rotational motions desired for a thrown softball 12.
The invention will be better understood with reference to the following non-limiting examples, which are illustrative only and not intended to limit the present invention to a particular embodiment.
In a first non-limiting example, a training tool 10 was provided by modifying a regulation baseball 12 to receive an indicator 14 in attachment thereto. The baseball 12 and indicator 14 had the following characteristics:
(1) Baseball 12
(2) Indicator 14
A hole 20 was formed in the baseball 12 to a depth of about 50.8 mm (about 2.0 inches) for receiving at least part of the indicator 14 therein. The weight of the baseball 12 was reduced to about 0.136 kg (about 4.80 ounces). The indicator 14 was mated with the hole 20 using an adhesive material. The total weight of the training tool 10 was about 0.153 kg (about 5.4 ounces).
In a second non-limiting example, a training tool 10 was provided by modifying a regulation baseball 12 to receive an indicator 14 in attachment thereto. The baseball 12 and indicator 14 had the following characteristics:
(1) Baseball 12
(2) Indicator 14
A hole 20 was formed in the baseball 12 to a depth of about 50.8 mm (about 2.0 inches) for receiving at least part of the indicator 14 therein. The weight of the baseball 12 was reduced to about 0.136 kg (about 4.80 ounces). The indicator 14 was mated with the hole 20 using an adhesive material. The total weight of the training tool 10 was about 0.162 kg (about 5.7 ounces).
In a third non-limiting example, a baseball related training tool 10 having the characteristics as described in Example 1 is provided. The training tool 10 includes a small motion sensor chip embedded within the indicator 14. The chip is in wireless communication with a computer. The chip is operationally configured to track rotational data for the training tool 10, which is relayed to computer software operationally configured to count, store and provide rotational data—from the moment the training tool 10 is released from a person's throwing hand to the moment the training tool 10 impacts a throwing target, e.g., a net or a catcher's mitt. Typically, the more rotations realized the greater the velocity of the thrown training tool 10. Thus, rotational counts are collected, stored and analyzed to evaluate changes in velocity for a particular individual according to one or more pitch types over a given period of time.
Persons of ordinary skill in the art will recognize that many modifications may be made to the present application without departing from the spirit and scope of the application. The embodiment(s) described herein are meant to be illustrative only and should not be taken as limiting the invention, which is defined in the claims.
The application is entitled to the benefit of the filing date of the prior-filed U.S. provisional application No. 61/763,191, filed on Feb. 11, 2013.
