Abstract

Abstract A method for training and warming-up baseball pitchers, using an apparatus comprising a closed loop of stretchable cord having a baseball or a simulated baseball mounted thereon. In accordance with one aspect of the method, the cord is secured to an anchor point spaced above the ground, and the pitcher slowly performs a simulated pitching movement while standing with his back to the anchor point and at a distance therefrom determined by the desired tension in the cord. In accordance with another aspect of the method, the pitching motion is performed without turning the pitching arm and wrist, and it is ascertained whether turning has occurred by sensing whether or not the upper fingers of the gripping hand of the pitcher engage portions of the cord at the baseball.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 174 words
A method of training a relatively young baseball pitcher to pitch without twisting his or her arm and wrist, said method comprising: (a) providing first and second sections of flexible elastic stretchable cord that connects to opposite sides of a spherical object in the nature of a baseball, (b) holding the end of the cord, remote from said baseball, so as to prevent substantial movement of said remote end, (c) gripping said baseball with a pitching grip, in such relationship to said first and second cord sections that the upper fingers of the pitcher do not touch either of said sections, (d) simulating a pitching movement while said baseball is thus gripped, while standing with the back toward said remote end of said cord, and while attempting to prevent the arm and hand from rotating, and (e) employing, as an indication of failure to perform said simulation step (d) properly, the fact that said upper fingers come into contact with one of said first and second cord sections at opposite sides of said baseball.
Claim 2
Independent Claim 174 words
A method of training a relatively young baseball pitcher to pitch without twisting his or her arm and wrist, said method comprising: (a) providing first and second sections of flexible elastic stretchable cord that connects to opposite sides of a spherical object in the nature of a baseball, (b) holding the end of the cord, remote from said baseball, so as to prevent substantial movement of said remote end, (c) gripping said baseball with a pitching grip, in such relationship to said first and second cord sections that the upper fingers of the pitcher do not touch either of said sections, (d) simulating a pitching movement while said baseball is thus gripped, while standing with the back toward said remote end of said cord, and while attempting to prevent the arm and hand from rotating, and (e) employing, as an indication of failure to perform said simulation step (d) properly, the fact that said upper fingers come into contact with one of said first and second cord sections at opposite sides of said baseball.
Claim 3
Dependent Claim 45 words
The invention as claimed in claim 1, in which said method further comprises causing said cord sections on opposite sides of said baseball to be portions of first and second elongated cord sections that extend from said baseball for a distance of a few feet.
Claim 4
Dependent Claim 67 words
The invention as claimed in claim 2, in which said method further comprises causing said cord sections to be parts of a continuous loop, and in which said method further comprises connecting the portion of said cord remote from said baseball to a stationary object at a substantial height above the ground, said substantial height being substantially that of the head of the person performing the method.
