Abstract
Abstract A synthetic pile carpet athletic game playing surface, such as for golf and the like, is formed with a relatively thick, loosely felted, springy fiber mat laid upon a stabilized base, with the pile carpet laid over the mat. The mat is filled with generally coarse, sand granules to provide a shock absorbent, compact resistant layer. The carpet is also filled with a sand granule layer of substantially the height of its pile fibers, and a flexible water barrier sheet is arranged between the carpet and the upper surface of the mat.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
124 words
A game playing surface, such as for golf, formed of a synthetic pile carpet positioned upon a stabilized support base surface, comprising: a relatively thick mat laid upon said support base surface, with said mat being formed of loosely felted, somewhat springy, coarse coconut hair fibers, so that the mat resiliently resists compacting; a filling of generally coarse sand granules which substantially fill the interstices between the mat fibers, wherein the filled mat forms a shock absorbent, compact resistant layer over the support base surface; a pile carpet laid over said mat, with the carpet formed of generally equal length, upwardly extending, synthetic fibers fastened at their lower ends to a carpet primary base sheet, so that the fibers give a substantially grass-like appearance;
Claim 2
Dependent Claim
124 words

Claim 3
Dependent Claim
43 words
a uniform thickness coating of sand-like granules covering the carpet primary base sheet and covering the fibers for a substantial portion of their heights, such as close to their upper free ends, and with the coating substantially filling the interstices between the fibers.
Claim 4
Dependent Claim
43 words
a uniform thickness coating of sand-like granules covering the carpet primary base sheet and covering the fibers for a substantial portion of their heights, such as close to their upper free ends, and with the coating substantially filling the interstices between the fibers.
Claim 5
Dependent Claim
42 words
A game playing surface as defined in claim 1, and including a water barrier pad arranged between the mat and the carpet; said pad being formed of a non-woven, flexible sheet which is substantially water impervious for diverting water from the mat.
Claim 6
Dependent Claim
27 words
A game playing surface as defined in claim 1, and including a rubber-like, resilient backing sheet bonded to the lower surface of the carpet primary backing sheet.
Claim 7
Dependent Claim
42 words
A game playing surface as defined in claim 3, and including a water barrier pad arranged between the mat and the carpet, with said pad being formed of a flexible sheet which is substantially water impervious for diverting water from the mat.
Claim 8
Dependent Claim
30 words
A game playing surface as defined in claim 4, and including a mesh-like flexible sheet fastened to the lower surface of the mat for engagement with the support base surface.
Claim 9
Dependent Claim
32 words
A game playing surface as defined in claim 1, and including an open mesh, flexible sheet fastened to the lower surface of the mat for frictional engagement with the support base surface.
Claim 10
Dependent Claim
25 words
A game playing surface as defined in claim 1, and including a relatively thick, resilient foam plastic layer interposed between the carpet and the mat.
Claim 11
Dependent Claim
42 words
A game playing surface as defined in claim 1, and including a rubber-like, resilient backing sheet bonded to the lower surface of the carpet primary backing sheet; and a relatively thick, resilient foam plastic layer arranged between the carpet and the mat.
