Abstract
Abstract Disclosed herein is a golf putting game comprising a flexible base layer of predetermined length, a plurality of smooth monofilament ribbons locked into the base layer from the back and protruding onto the front face thereof to form a surface simulating a putting green, the ribbons extending for a predetermined essentially uniform first height above the base layer and being resilient, a supplemental backing layer bonded to said base layer and having a high coefficient of friction, a group of fibers having a substantially lower resiliency than the ribbons are anchored in the backing layer and extend through it and the base layer to an essentially uniform second height above the base. The second group of fibers is arrayed in a circular configuration to form a raised ring having the same interior diameter as a golf cup on the putting surface.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
164 words
A practice putting game comprising a flexible base layer of predetermined length, a plurality of smooth monofilament fibers locked into said base from the back and protruding through the front surface thereof to form a simulated golf green surface, said fibers having a predetermined essentially uniform first height above said base, a continuous wear layer comprising a material having a high coefficient of friction covering the back of said base, a group of upright fibers anchored in said wear layer and protruding from said base through said monofilament fibers to a substantially uniform second height above said first height, said group of upright fibers being arrayed in a circle to define a raised ring, said ring having a predetermined interior diameter on the surface of said green, and said upright fibers being substantially less resilient than said monofilament fibers to permit a ball rolling on said monofilament fibers to pass through the circle of said upright fibers and into the interior of said ring.
Claim 2
Dependent Claim
164 words
A practice putting game comprising a flexible base layer of predetermined length, a plurality of smooth monofilament fibers locked into said base from the back and protruding through the front surface thereof to form a simulated golf green surface, said fibers having a predetermined essentially uniform first height above said base, a continuous wear layer comprising a material having a high coefficient of friction covering the back of said base, a group of upright fibers anchored in said wear layer and protruding from said base through said monofilament fibers to a substantially uniform second height above said first height, said group of upright fibers being arrayed in a circle to define a raised ring, said ring having a predetermined interior diameter on the surface of said green, and said upright fibers being substantially less resilient than said monofilament fibers to permit a ball rolling on said monofilament fibers to pass through the circle of said upright fibers and into the interior of said ring.
Claim 3
Dependent Claim
16 words
The practice putting game according to claim 1 wherein said monofilament fibers comprise an olefin composition.
Claim 4
Dependent Claim
15 words
The practice putting game of claim 2 wherein said monofilament fibers comprise smooth polypropylene ribbons.
Claim 5
Dependent Claim
22 words
The practice putting game of claim 3 wherein said polypropylene ribbons protrude about 1/2 inch above the surface of said base layer.
Claim 6
Dependent Claim
19 words
The practice putting game of claim 4 wherein said upright group of fibers comprises a plurality of multifilament yarns.
Claim 7
Dependent Claim
15 words
The practice putting game of claim 5 wherein said wear layer is formed of rubber.
Claim 8
Dependent Claim
32 words
The practice putting game according to claim 6 comprising two raised rings located at spaced apart points on said green surface, the centers of said rings being in alignment with each other.
Claim 9
Dependent Claim
41 words
The practice putting game according to claim 7 wherein said golf green surface is a sheared pile fabric formed of a plurality of tufted monofilament ribbons anchored in said base layer and held in said base layer by said wear layer.
Claim 10
Dependent Claim
17 words
The practice putting game of claim 3 wherein said base layer comprises a closely woven synthetic material.
Claim 11
Dependent Claim
19 words
The practice putting game according to claim 3 wherein said upright group of fibers are formed of nylon composition.
Claim 12
Dependent Claim
31 words
The putting game of claim 1 in which said upright fibers are formed into a plurality of tufts arranged in a plurality of adjacent concentric circles to define said raised ring.
Claim 13
Dependent Claim
27 words
The putting game of claim 1 in which said monofilament fibers comprise high resilience synthetic material and said upright fibers comprise relatively low resilience natural textile filaments.
