Abstract

Abstract A longitudinal member, with a dimple to receive a golf ball, and an elongated indicia design, contains a reflective insert between a pair of parallel walls to indicate the position of the user's eyes relative to the ball and also includes a retaining bar supported by said walls to encourage a square, accelerating putting stroke.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 136 words
A longitudinal channel the major portion of whose interior surface is composed of nonreflective material; the channel having walls on the longer sides; the channel containing a dimple in which to receive a golf ball; a reflective area centrally located in said channel and adjacent to said dimple; the channel having an elongated indicia extending down a major portion of the longitudinal center of the channel; the width of the channel being slightly greater than the width of a standard putting clubhead; a retaining bar provided to fit in the parallel walls through various openings and perpendicular to said indicia; the parts being so constructed and arranged that the reflective area gives an optical indication when the eye of the user is aligned vartically above the longitudinal center, and on line with the center of impact.
Claim 2
Dependent Claim 136 words
A longitudinal channel the major portion of whose interior surface is composed of nonreflective material; the channel having walls on the longer sides; the channel containing a dimple in which to receive a golf ball; a reflective area centrally located in said channel and adjacent to said dimple; the channel having an elongated indicia extending down a major portion of the longitudinal center of the channel; the width of the channel being slightly greater than the width of a standard putting clubhead; a retaining bar provided to fit in the parallel walls through various openings and perpendicular to said indicia; the parts being so constructed and arranged that the reflective area gives an optical indication when the eye of the user is aligned vartically above the longitudinal center, and on line with the center of impact.
Claim 3
Dependent Claim 81 words
A golf putting aid comprising; a rectangular longitudinal member of substantially non-reflective material; said member having a pair of longitudinal sidewalls; a dimple on the longitudinal axis of said member for receiving a golf ball; a centrally located reflective area adjacent to said dimple; a visible longitudinal indicia extending for a major portion of the length of said channel and equidistant from said sidewalls, and; a movable rod member mounted in said sidewalls transverse the longitudinal axis of said longitudinal member.
Claim 4
Dependent Claim 81 words
A golf putting aid comprising; a rectangular longitudinal member of substantially non-reflective material; said member having a pair of longitudinal sidewalls; a dimple on the longitudinal axis of said member for receiving a golf ball; a centrally located reflective area adjacent to said dimple; a visible longitudinal indicia extending for a major portion of the length of said channel and equidistant from said sidewalls, and; a movable rod member mounted in said sidewalls transverse the longitudinal axis of said longitudinal member.
Claim 5
Dependent Claim 27 words
The combination in accordance with claim 2 wherein said indicia extends for the length of said longitudinal member except for the longitudinal dimension of said reflective area.
Claim 6
Dependent Claim 67 words
The combination in accordance with claim 2 wherein said longitudinal member is slightly wider than the width of the average golf putter; said average being 4 inches; wide enough to guide the putter squarely but not so as to restrict the swing; said width of channel being 6 inches so that putters ranging from 31/2 to 5 inch stay square to the line and yet swing freely.
