Independent Claim
125 words
A golf swing analysis mat comprising: a backing; a plurality of pliable substantially non resilient, integral fibers, said fibers having a lower portion secured to said backing and an upper portion being bendable from a first normally upstanding position to a second position angularly disposed thereto, whereby said fibers will remain in said first or said second position in the absence of outside forces being applied thereto; and indicating means on said fibers for indicating whether said fibers are in said first or second position, said indicating means including a first color on a first side of said fibers and a second color on a second side of said fibers whereby when said fibers are in said second position, said second color is not visible.
Claim 2
Dependent Claim
125 words
A golf swing analysis mat comprising: a backing; a plurality of pliable substantially non resilient, integral fibers, said fibers having a lower portion secured to said backing and an upper portion being bendable from a first normally upstanding position to a second position angularly disposed thereto, whereby said fibers will remain in said first or said second position in the absence of outside forces being applied thereto; and indicating means on said fibers for indicating whether said fibers are in said first or second position, said indicating means including a first color on a first side of said fibers and a second color on a second side of said fibers whereby when said fibers are in said second position, said second color is not visible.
Claim 3
Dependent Claim
