Abstract
Abstract The training device for improving a baseball batter's swing includes a forward foot actuated switch which is normally open but is closed when the baseball batter takes the short forward foot step during the batter's swing. A wrist movement switch in one embodiment is mechanically linked to a wrist strap on the aft or rearward wrist of the batter. The wrist switch is normally closed and is subsequently opened due to the swinging motion of the wrist during the batter's swing movement. An alarm system is coupled to the foot switch and the wrist switch and further includes, in one embodiment, an audible alarm device which is activated thereby issuing an alarm upon a predetermined sequential movement of the batter's forward foot and wrist during the swing movement. The predetermined sequential movement is the batter's short step, that closes the foot switch, prior to the batter's swinging of the wrist. Movement of the wrist during the bat swing opens the wrist switch and deactivates the alarm. The alarm sounds when the foot switch is closed and the wrist switch remains closed due to the batter taking the short foot step prior initiating the bat swing as sensed by wrist movement.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
113 words
A training device for a batter swinging a baseball bat comprising: a forward foot actuated switch means adapted to be actuated by a forward placed foot of said batter during a short foot step of a batter's swing movement; a wrist movement actuated switch means coupled to a wrist of said batter and adapted to be actuated by a swing motion of said wrist during said batter's swing movement; and, an alarm system coupled to said foot switch means and said wrist switch means, said alarm system having means for issuing an alarm based upon a predetermined sequential movement of said batter's forward foot and said batter's wrist during said batter's swing movement.
Claim 2
Dependent Claim
113 words
A training device for a batter swinging a baseball bat comprising: a forward foot actuated switch means adapted to be actuated by a forward placed foot of said batter during a short foot step of a batter's swing movement; a wrist movement actuated switch means coupled to a wrist of said batter and adapted to be actuated by a swing motion of said wrist during said batter's swing movement; and, an alarm system coupled to said foot switch means and said wrist switch means, said alarm system having means for issuing an alarm based upon a predetermined sequential movement of said batter's forward foot and said batter's wrist during said batter's swing movement.
Claim 3
Dependent Claim
20 words
A training device as claimed in claim 1 wherein the means for issuing said alarm includes an audible alarm device.
Claim 4
Dependent Claim
76 words
A training device as claimed in claim 2 wherein said foot switch means is in a normally open state, said wrist switch means is in a normally closed state, and said means for issuing an alarm actuates said audible alarm device when said batter's forward foot actuates said foot switch means during said short foot step prior to actuation of said wrist switch means during said swing motion of said wrist as said predetermined sequential movement.
Claim 5
Dependent Claim
28 words
A training device as claimed in claim 1 wherein said foot switch means, said wrist switch means and said means for issuing an alarm are electrically coupled together.
Claim 6
Dependent Claim
31 words
A training device as claimed in claim 4 wherein said wrist switch means includes a wrist attachment for said batter's wrist and a mechanically actuated switch linked to said wrist attachment.
Claim 7
Dependent Claim
31 words
A training device as claimed in claim 2 wherein said foot switch means includes a pressure sensitive plate adapted to be depressed during said short step of said batter's swing movement.
Claim 8
Dependent Claim
29 words
A training device as claimed in claim 5 wherein said wrist switch means further includes a cable and pulley linkage between said wrist attachment and said mechanically actuated switch.
Claim 9
Independent Claim
115 words
A method for training a batter swinging a baseball bat comprising the steps of: sensing a physical attribute of a short foot step of a forward placed foot of a batter during a batter's swing movement; sensing a physical attribute of a wrist movement of a rearward wrist of a batter during the batter's swing movement; issuing an alarm directed at said batter based upon the physical attributes of said forward foot and said wrist when the foot sensing step senses the short foot step prior to sensing the wrist movement during the batter's swing movement; and, not issuing an alarm in the absence of sequentially sensing the foot step prior to the wrist movement.
Claim 10
Independent Claim
115 words
A method for training a batter swinging a baseball bat comprising the steps of: sensing a physical attribute of a short foot step of a forward placed foot of a batter during a batter's swing movement; sensing a physical attribute of a wrist movement of a rearward wrist of a batter during the batter's swing movement; issuing an alarm directed at said batter based upon the physical attributes of said forward foot and said wrist when the foot sensing step senses the short foot step prior to sensing the wrist movement during the batter's swing movement; and, not issuing an alarm in the absence of sequentially sensing the foot step prior to the wrist movement.
