Abstract

Abstract An aid in practicing putting comprising an elongated flat base and upon said base a channel of U-shaped cross-sectional contour with its side flanges disposed longitudinally of said base. Along their inner surfaces these side flanges are provided with rows of transversely aligned, longitudinally equispaced flaps of flexible material and of preferably semicircular contour. Transversely of the channel, these flaps are spaced from each other by a distance slightly larger than the length of the putter blade. Target means for a golf ball is arranged on the base in an area thereof spaced from one of the open ends of the channel in the vertical plane of symmetry thereof. When a golfer wishes to putt a golf ball from a point on the floor of the channel onto the target means, the blade of his putter must stay free of the opposed flaps on the side flanges of the channel for the stroke to be perfect. If his putter blade touches any one of these flaps, the golfer senses this immediately and knows that his putting stroke is faulty.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 39 words
An aid in practicing putting comprising a channel of U-shaped cross-sectional contour having a pair of transversely spaced longitudinally extending side flanges and projecting from the inner surfaces of said flanges rows of longitudinally spaced flaps of flexible material.
Claim 2
Dependent Claim 39 words
An aid in practicing putting comprising a channel of U-shaped cross-sectional contour having a pair of transversely spaced longitudinally extending side flanges and projecting from the inner surfaces of said flanges rows of longitudinally spaced flaps of flexible material.
Claim 3
Dependent Claim 26 words

Claim 6
Dependent Claim 94 words
An aid in practicing putting comprising an elongated flat base, upon said base a channel of U-shaped cross-sectional contour with its side flanges extending longitudinally of said base, rows of longitudinally spaced flaps of flexible material projecting from the inner surfaces of said side flanges with their inner edges spaced apart by a distance slightly larger than the length of a putter blade, and in an area of said base removed from one end of said channel and within the longitudinal vertical plane of symmetry of said channel target means for a golf ball.
Claim 7
Dependent Claim 94 words
An aid in practicing putting comprising an elongated flat base, upon said base a channel of U-shaped cross-sectional contour with its side flanges extending longitudinally of said base, rows of longitudinally spaced flaps of flexible material projecting from the inner surfaces of said side flanges with their inner edges spaced apart by a distance slightly larger than the length of a putter blade, and in an area of said base removed from one end of said channel and within the longitudinal vertical plane of symmetry of said channel target means for a golf ball.
Claim 8
Dependent Claim 34 words
