DEVICE FOR PRACTICING THROWING A BALL
A device (10) for practicing throwing a ball (24) includes an elongated bag (12) having an opening (14) at one end thereof with a second end (16) of the bag being closed. A flexible sleeve (18) is fixed to the bag around a perimeter of the opening of the bag. The flexible sleeve and the opening in the bag allow a hand (26) of a person to pass through the sleeve and the opening. A cinching strap (20) provided with a hook and loop fastening system (22) is fixed to the sleeve. A ball is placed inside the bag, and a hand of a person is passed through the sleeve into the bag. The device is secured to a forearm or wrist of the person such that the device will not become separated from the person when the person has his hand in the bag with a ball grasped by his hand and releases the ball from his grasp when making a throwing motion.
This is a non provisional application claiming priority of provisional application Ser. No. 61/288,312 filed Dec. 20, 2009.
FIELD OF THE INVENTIONThe present invention relates to a device for practicing throwing a ball, such as a baseball, softball, football or any ball that can be thrown with one hand.
BACKGROUND OF THE INVENTIONNormally, throwing a ball, such as a baseball, softball, any ball that can be thrown with one hand, results in the ball traveling some distance from the thrower, which requires either that a second person be positioned to catch and return the ball to the thrower, or that the thrower leave his throwing location to retrieve the ball. Throwing a ball indoors encompasses the risk of unintended damage to objects in the enclosed area. It is desirable to have a device that would allow a person to practice throwing a ball without the need for another person to catch and return the thrown ball and without the risk of causing property damage if a ball is thrown indoors. The present invention provides a device that addresses both of these problems.
DISCUSSION OF THE PRIOR ARTU.S. Pat. No. 7,563,183 B2 discloses the use of “indicator bands” attached to the wrist of a throwers arm such that by practicing a throwing motion the resultant positions of the indicator bands teach indicate whether proper throwing is occurring. The device of U.S. Pat. No. 7,563,183 B2 does not require the person being trained and evaluated to actually grasp a ball during the use of the device, which does allow it to be used safely indoors. However, this is a drawback because the grip used to grasp a ball is a major influence upon the behavior of a thrown ball. The use of the device of the present invention allows a thrower to grasp a ball and release the ball in a throwing motion safely indoors.
SUMMARY OF THE INVENTIONThe present invention provides a device for practicing throwing a ball wherein the device includes an elongated bag having an opening at one end thereof with a second end of the bag being closed. A flexible sleeve is fixed to the bag around a perimeter of the opening of the bag. The flexible sleeve and the opening in the bag allow a hand of a person to pass through the sleeve and the opening. A cinching strap (20) provided with a hook and loop fastening system is fixed to the sleeve. A ball is placed inside the bag, and a hand of a person is passed through the sleeve into the bag. The device is secured to a wrist or forearm of the person such that the device will not become separated from the person when the person has his hand in the bag with a ball grasped by his hand and releases the ball from his grasp when making a throwing motion.
The new device has utility for teaching proper throwing technique, rehabilitation of an injury in the throwing hand, arm, shoulder or other body parts, and in warming up before participating in practice or competition.
The end of the bag having the opening 14 is fixed to a means 18, 20 for securing the device to a forearm or wrist of the person such that the device will not become separated from the person when the person has his hand in the bag with a ball grasped by his hand and releases the ball from his grasp when making a throwing motion.
In the drawing figures the means for securing the device to the forearm of the person is a flexible sleeve 18 that is fixed to the bag around a perimeter of the opening 14 of the bag 12 and a means 20 for tightening the sleeve around at least one of the forearm or wrist of a person. The sleeve may comprise an elastic material or any other suitable material. As used herein and in the claims the term “elastic material” is understood to refer to a flexible stretchable fabric made with interwoven strands of rubber or an imitative synthetic fiber, the fabric attempting to return to an initial form after deformation. The flexible sleeve 18 is fixed to the bag 12 around a perimeter of the opening 14 of the bag. Both the flexible sleeve and the opening in the bag allow a hand of a person to pass through the sleeve and the opening in the bag. Further, a ball 24 can pass through the sleeve and the opening in the bag. As a point of reference in sizing these components it is noted that diameter of a regulation size baseball is about 2.9 inches.
The sleeve is provided with a means for securing the sleeve in place with respect to the forearm and wrist of a user. A tightening member 20 is provided for extending around an exterior surface of the flexible sleeve 18 such that the tightening member can be cinched around the sleeve with a means 22 for maintaining a cinched state of the tightening member. In the drawings a cinching strap 20 is fixed to the sleeve 18 and the cinching strap is provided with a fastening system 22 to secure the flexible sleeve in place with respect to the wrist and forearm of a user, such as a buckle, elastic band, knot, one or more snaps, a hook and loop fastening system. An example of a hook and loop fastening system is marketed under the trademark Velcro®. The hook tape presents a rough or hard side for mating with the loop tape that presents a soft or fuzzy side. The hook and loop tapes may be secured to the straps by sewing, adhesive or any other suitable means.
In a prototype of the device the elongated bag 12 has a width when laid flat of about 7.75 inches and a length of about 15 inches as measured from the end of the flexible sleeve. The flexible sleeve when laid flat has a length of about 6.5 inches and a width of about 3 inches. It is to be understood that these dimensions are merely exemplary, and that the device may be manufactured in sizes suitable to children, youth and adults of various sizes. While the bag before assembly with the sleeve may have a substantially rectangular shape when laid flat, it is understood that the bag may be of a tubular configuration. The sleeve may be fixed to the sleeve in any suitable manner such as sewing, weaving, adhesive, heat welding and so forth. The cinch strap may be fixed to the flexible sleeve by any suitable means including sewing, weaving, adhesive, heat welding and so forth. However, it is understood that a cinch strap or other suitable means for securing the sleeve in place around the forearm and wrist of a user may be a separate component that is not permanently fixed to the sleeve, and is applied after the user has inserted his hand, wrist and forearm into the device.
