Abstract
Abstract A display rack adapted to support and display a plurality of golf clubs, specifically putters. The rack has an alignment system associated therewith for permitting a golfer to analyze his putting stance and select a putter having the proper shaft angle. The alignment system includes an elongated vertically extending sight tube mounted on the rack and positioned above an alignment mark which represents the position of a golf ball. The sight tube has a calibrated arm projecting horizontally therefrom and adapted to be positioned adjacent the shaft of a putter when the head thereof is disposed adjacent the alignment mark. The calibrating arm has calibrations thereon which indicate the angle assumed by the putter shaft relative to the vertical axis of the sight tube.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
122 words
A device for determining the proper shaft angle for a putter, comprising: stationary base means having a substantially horizontal plate adapted to be disposed on the floor, said plate having an alignment mark thereon; vertical sighting means mounted on said base means and spaced upwardly from said plate, said sighting means being vertically aligned with said mark; said vertical sighting means comprising an elongated hollow tube positioned vertically and defining a vertical line of sight which is substantially aligned with said mark, said tube having the lower end thereof spaced upwardly from said plate; and means coacting with said sighting means for determining the angle of a putter shaft relative to the vertical when the putter head is located adjacent said mark.
Claim 2
Independent Claim
122 words
A device for determining the proper shaft angle for a putter, comprising: stationary base means having a substantially horizontal plate adapted to be disposed on the floor, said plate having an alignment mark thereon; vertical sighting means mounted on said base means and spaced upwardly from said plate, said sighting means being vertically aligned with said mark; said vertical sighting means comprising an elongated hollow tube positioned vertically and defining a vertical line of sight which is substantially aligned with said mark, said tube having the lower end thereof spaced upwardly from said plate; and means coacting with said sighting means for determining the angle of a putter shaft relative to the vertical when the putter head is located adjacent said mark.
Claim 3
Dependent Claim
34 words
A device according to claim 1, wherein said hollow tube has an opening extending therethrough which has a diameter which is of the same order of magnitude as the diameter of a golf ball.
Claim 4
Dependent Claim
34 words
A device according to claim 1, wherein the means for determining the angle of a putter shaft includes an arm projecting substantially horizontally away from the vertical sight line defined by said sighting means.
Claim 5
Dependent Claim
25 words
A device according to claim 3, further including means mounting said arm for swinging movement relative to said base means about a substantially vertical axis.
Claim 6
Dependent Claim
22 words
A device according to claim 3, wherein said arm is horizontally swingable relative to said base means about said vertical sight line.
Claim 7
Dependent Claim
25 words
A device according to claim 5, wherein said arm has an upper surface with indicia thereon for visually indicating the angle of a putter shaft.
