Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
77 words
A golf practice device for use in perfecting a golf swing comprising in combination: a base having affixed thereto a turflike mat, wherein said base and said turf-like mat include a plurality of linearly disposed ball supporting means, and wherein said base has a leg extending substantially perpendicularly from one side of said base; having affixed thereto a vertically adjuStable indicating member which provides linear and arcuate motion substantially along a longitudinal axis of the perpendicular extension.
Claim 2
Dependent Claim
77 words
A golf practice device for use in perfecting a golf swing comprising in combination: a base having affixed thereto a turflike mat, wherein said base and said turf-like mat include a plurality of linearly disposed ball supporting means, and wherein said base has a leg extending substantially perpendicularly from one side of said base; having affixed thereto a vertically adjuStable indicating member which provides linear and arcuate motion substantially along a longitudinal axis of the perpendicular extension.
Claim 3
Dependent Claim
77 words
A golf practice device for use in perfecting a golf swing comprising in combination: a base having affixed thereto a turf-like mat, wherein said base and said turf-like mat include a plurality of linearly disposed ball supporting means, and wherein said base has a leg extending substantially perpendicularly from one side of said base; having affixed thereto a vertically adjuStable indicating member which provides linear and arcuate motion substantially along a longitudinal axis of the perpendicular extension.
Claim 4
Dependent Claim
77 words
A golf practice device for use in perfecting a golf swing comprising in combination: a base having affixed thereto a turf-like mat, wherein said base and said turf-like mat include a plurality of linearly disposed ball supporting means, and wherein said base has a leg extending substantially perpendicularly from one side of said base; having affixed thereto a vertically adjuStable indicating member which provides linear and arcuate motion substantially along a longitudinal axis of the perpendicular extension.
Claim 5
Dependent Claim
30 words
The golf practice device of claim 1, wherein the ball supporting means are tees disposed linearly substantially along the longitudinal axis of the base and protrude above the turf-like mat.
Claim 6
Dependent Claim
15 words
The golf practice device of claim 2, wherein the turf-like mat resembles naturally occurring grass.
Claim 7
Dependent Claim
15 words
The golf practice device of claim 2, wherein said base is planar and substantially rectangular.
Claim 8
Dependent Claim
60 words
The golf practice device of claim 1, wherein the vertically adjustable indicating member is a telescoping tubular member and wherein the means to retain said vertically adjustable indicating member is a track affixed to the perpendicular leg substantially parallel to the longitudinal axis of said leg; wherein said track permits linear and arcuate motion of said vertically adjustable indicating member.
Claim 9
Dependent Claim
29 words
The golf practice device of claim 5, wherein the means to provide linear and arcuate motion of the vertically adjustable member in said track is a ball-and-socket type joint.
Claim 10
Dependent Claim
24 words
The golf practice device of claim 5 wherein said leg extending substantially perpendicularly from one side of said base is co-planar with said base.
Claim 11
Dependent Claim
26 words
The golf practice device of claim 1, wherein said base includes a means of attachment to the ground to provide increased stability thereof when used out-of-doors.
