Pitcher's training device
A pitcher's training device is provided for training a softball or baseball pitcher in gripping and spinning a ball for special pitches, such as fastball, curve ball or screwball pitches. The pitcher's training apparatus includes a base which may be in the form of a folding tripod with a central column that can be raised and lowered to adjust for the person being trained. A training ball supporting arm is attached to and extends from the base and may be positioned for different pitchers. The supporting arm has an elongated slot passing through the side thereof. A pair of practice balls are connected by a shaft extending through the arm slot so that a pitcher can practice the gripping and spinning of the training ball forcing the ball shaft to spin and move in the slot.
This application claims the benefit of U.S. Provisional Application No. 60/658,643, filed Mar. 7, 2005.
BACKGROUND OF THE INVENTIONThe present invention relates to a pitcher's training device and especially to a pitcher's training device used in baseball or softball and especially a training device for fast pitch softball. It is especially useful in teaching proper technique for pitching fastballs, curve balls, screwballs, and rise and drop pitches.
Proper throwing, especially when pitching, requires the person throwing the ball to impart a particular spin or rotation to the ball upon release of the ball from the pitching hand. The exception to this is the knuckle ball which is deliberately delivered in such a manner that the spin or rotation is minimized or non-existent. A fastball is thrown such that as the ball moves towards the plate, the top of the ball rotates towards the release hand of the pitcher and away from the plate. A curve ball is thrown so that the top of the ball rotates away for the release hand of the pitcher and towards the plate. Each pitch requires a particular arm angle and wrist motion to deliver the ball to the plate in the desired manner.
Various techniques exist for teaching proper throwing pitching techniques, such as that seen in the Barth U.S. Pat. No. 5,743,808 for a Baseball Throwing Trainer which has two baseballs connected together with a dowel screw. The student grips either ball in an appropriate manner for a pitch being thrown and flips or throws a ball while trying to impart rotation to the ball. The U.S. Pat. No. to Simpson 6,471,606 shows a device for creating ball spins which has a ball spinning device having a plurality of balls attached thereto. In the Romanick U.S. Pat. No. 5,830,091, a sports ball throwing training device audibly indicates proper throwing mechanics and has a sports ball attached to an elongated hollow tubular member with a closed end and having a freely movable inner dowel in the tubular member. The Kempf U.S. Pat. No. 5,472,187 teaches a Ball Pitch Training Device to facilitate a user learning to make a better pitching release and motion so that a ball, when pitched, will have a proper rotation to achieve maximum velocity and accuracy and is generally disc-shaped.
In contrast, the present invention is specifically directed towards an aid for training a student's speciality pitches in fast pitch softball in which the pitcher grips and spins a softball tandem with proper followthrough to generate spin and translation of the connected ball. The student receives feedback on his technique by the motion of the tandemly connected balls moving within an elongated slot.
SUMMARY OF THE INVENTIONA pitcher's training device is provided for training a softball or baseball pitcher in gripping and spinning a ball for special pitches, such as fastball, curve ball or screwball pitches. The pitcher's training apparatus includes a base which may be in the form of a folding tripod with a central column that can be raised and lowered to adjust for the person being trained. A training ball supporting arm is attached to and extends from the base and may be positioned for different pitchers. The supporting arm has an elongated slot passing through the side thereof. A practice ball has a shaft extending therefrom which shaft is rotatably and moveably attached through the supporting arm slot so that a pitcher can practice the gripping and spinning of the training ball forcing the ball shaft to spin and move in the slot. A pair of balls may be attached to the shaft which extends through the training ball supporting arm slot and the supporting arm may be rotated to different positions. The training ball supporting arm may also be a straight supporting arm or a curved one in which the slot extends through the curved portion. The pitcher's training apparatus allows a pitcher to adjust the position of the training ball supporting arm having the practice ball and shaft attached through the slot therein. Spinning the ball in a manner for pitching a fastball, curve ball, screwball or the like then moves the practice ball and attached shaft rotating in the supporting arm slot to move across the slot.
BRIEF DESCRIPTION OF THE DRAWINGSOther objects, features, and advantages of the present invention will be apparent from the written description and the drawings in which:
Referring to the drawings and especially to
This particular embodiment of the present pitcher's training device is for training a pitcher's wrists for throwing a curve ball or screwball pitch and trains the pitcher's wrist motion for making a softball pitch. The student thus grabs either the ball 24 or 25, depending on whether the pitcher is a left handed or right handed pitcher, with the appropriate grip for the particular ball game and imparts a spin into the ball of the type required for a curve ball or a screwball. Once the ball 24, 25 is rotated in this manner, rotating the dowel 26, the pair of balls 24,25 will, following the spin, extend through the slot to follow the slot 23 in the arm 21 when the appropriate spin is imparted to one of the balls. Continuous rote practice while spinning a ball in this nature teaches the pitcher the proper wrist motion in throwing the softball for producing a curve ball.
Turning to
Turning to
It will be clear at this time that an aide for training a pitcher's wrist, especially for use in fast pitch softball, has been provided in which interchangeable arms can be utilized for training the wrist of a pitcher in different pitches. However, it will also be clear that two or all three of the training arms can be mounted together on one tripod base so that all three can be practiced from different positions around the tripod. In addition, it will be clear that the tripod base is only one means for supporting the upright column and training arms so that any other support can be utilized without departing from the spirit and scope of the invention. It is however desirable to have a vertical column which can be adjusted for the height of different pitchers using the practice device. Accordingly, the present invention is not to be construed as limited to the forms shown which are to be considered illustrative rather than restrictive.
