The present invention relates generally to devices and methods for training athletes, and more particularly to devices and methods for training baseball pitchers.
Baseball pitchers commonly use an exercise known as “throw the towel” to improve the follow-through of their delivery. In this exercise, a small hand towel is knotted at one end, and the pitcher grips the knotted end in his/her pitching hand as if it were a baseball. The pitcher then completes his/her delivery without releasing the towel. Audible “snapping” of the unknotted end of the towel at the completion of the pitcher's delivery is indicative of a full follow-through and efficient pitching mechanics. In addition to providing feedback to improve pitching mechanics, the “throw the towel” exercise also provides resistive training for arm muscles and increases arm speed.
But the conventional “throw the towel” exercise falls short of simulating an actual pitcher's delivery in several respects. The towel knot does not have the size, shape or weight of an official baseball, nor does it have a baseball's seams, by which the pitcher's fingers grip the ball. Moreover, because the knot cannot move independently of the entire towel, the ability of the pitcher's hand to rotate as he/she completes his/her delivery is severely constrained. The lack of seams on the towel knot also prevents the trainee pitcher from practicing different grips associated with various pitches, such “four-seam” and “two-seam” fastballs, change-ups and assorted breaking pitches.
In order to better simulate the mechanics of a pitcher's delivery, the present invention provides a training device comprising an official-size baseball with an attached sheet-like, pliable tail member. The baseball has the traditional horseshoe-shaped seams, which may be stitched seams or simulated stitching.
The tail member is attached to the baseball through one of multiple apertures, which are variously positioned relative to the seams, so as to allow the trainee pitcher to alter his/her grip on the seams without obstruction from the tail member. This feature is advantageous because it allows the trainee pitcher to practice a variety of pitches calling for different grips on the seams.
Preferably, the tail member is attached to the baseball so that the ball is free to rotate independently of the tail member. This feature allows the trainee to apply rotation to the ball in the course of his/her delivery, as he/she would in actually delivering a pitch. Rotatable attachment of the tail member to the baseball can be accomplished by the conjugate coupling of a spherical extension at the proximal end of the tail member with a spherical socket inside the baseball.
Optimally, the shape of the tail member is substantially rectangular, with a proximal corner attached to the baseball and a distal corner that snaps upon completion of a pitching delivery with full follow-through. Interchangeable tail members of various sizes can be provided, so that a trainee pitcher can progress from smaller to larger tail members as his/her arm strength increases.
The foregoing summarizes the general design features of the present invention. In the following sections, specific embodiments of the present invention will be described in some detail. These specific embodiments are intended to demonstrate the feasibility of implementing the present invention in accordance with the general design features discussed above. Therefore, the detailed descriptions of these embodiments are offered for illustrative and exemplary purposes only, and they are not intended to limit the scope either of the foregoing summary description or of the claims which follow.
