Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
78 words
A practice putting green assembly, said assembly comprising a playing mat having a putting end, a ball cup in said mat, and means for adjusting a topography of said green, said adjusting means being above said playing mat and including a support structure having an interior channel, said adjusting means further including a plurality of elongated members extending at least partially through said interior channel in said support structure for raising and lowering parts of said playing mat.
Claim 2
Dependent Claim
78 words
A practice putting green assembly, said assembly comprising a playing mat having a putting end, a ball cup in said mat, and means for adjusting a topography of said green, said adjusting means being above said playing mat and including a support structure having an interior channel, said adjusting means further including a plurality of elongated members extending at least partially through said interior channel in said support structure for raising and lowering parts of said playing mat.
Claim 3
Dependent Claim
25 words
The practice putting green assembly of claim 1 wherein said adjusting means can selectively elevate a section of said playing mat adjacent said ball cup.
Claim 4
Dependent Claim
25 words
The putting green assembly of claim 1 wherein said elongated members selectively elevate parts of said playing mat to create a plurality of inclines therein.
Claim 5
Dependent Claim
34 words
The practice putting green assembly of claim 1 wherein a plurality of balls can be returned to said putting end by pulling one of said elongated members and causing said playing mat to incline.
Claim 6
Dependent Claim
32 words
The practice putting green assembly of claim 1 wherein at least one of said elongated members extends outside said interior channel and is attached to an external surface of said support structure.
Claim 7
Dependent Claim
35 words
The practice putting green assembly of claim 1 including protruding means on at least one of said elongated members and wherein said support structure includes at least one detent means for engaging said protruding means.
Claim 8
Dependent Claim
16 words
The practice putting green assembly of claim 1 wherein said ball cup includes an inclined bottom.
Claim 9
Dependent Claim
19 words
