Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
114 words
A batter's training device comprising a planar sheet material defining a first area for receiving a batter's rear pivot foot and a second area for receiving a batter's leading stride foot, said second area being spaced apart from said first area and said second area having a first length, means adjacent at least one of said first or said second foot areas for adjustably setting a distance between said first and second areas and means adjacent said second area for altering said first length to a second length, whereby the adjusting of such distance between such first and second areas defines a desired stance and the altering of such lengths defines a desired stride.
Claim 2
Dependent Claim
114 words
A batter's training device comprising a planar sheet material defining a first area for receiving a batter's rear pivot foot and a second area for receiving a batter's leading stride foot, said second area being spaced apart from said first area and said second area having a first length, means adjacent at least one of said first or said second foot areas for adjustably setting a distance between said first and second areas and means adjacent said second area for altering said first length to a second length, whereby the adjusting of such distance between such first and second areas defines a desired stance and the altering of such lengths defines a desired stride.
Claim 3
Dependent Claim
74 words
A batter's training device comprising a planar sheet material defining a first area for receiving a batter's pivot foot and a second area for receiving a batter's stride foot, first closure means adjacent at least one of said first or said second areas for adjustably setting a first distance between said first and said second areas and second closure means adjacent said second area for adjustably changing the length dimension of said second area.
Claim 4
Dependent Claim
74 words
A batter's training device comprising a planar sheet material defining a first area for receiving a batter's pivot foot and a second area for receiving a batter's stride foot, first closure means adjacent at least one of said first or said second areas for adjustably setting a first distance between said first and said second areas and second closure means adjacent said second area for adjustably changing the length dimension of said second area.
Claim 5
Dependent Claim
