Abstract
Abstract Method and device is provided for recording the swing of a golf club over a mat and permitting the analysis of the depth of the swing, the arc of the swing and the angle of the face of the golf club head when it contacts the mat. A resilient mat is covered with a thin film of chalk dust and a golf club having an attachment secured to the golf club head capable of dispersing the dust on the mat when it contacts the mat. The dust is dispersed in a pattern on the mat, which due to the attachment, permits analysis to determine the foregoing. The mat may also be provided with indicia related to a golf ball and the equivalence of making a divot by the golfer may also be determined.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
255 words
A method for analyzing both the depth and arc of swing of a golfer swinging a golf club head over a mat having indicia simulating golf ball thereon and analyzing the angle of the face of the golf club head when contacting said mat comprising the steps of: dispersing a relatively thin film of relatively soft fine dry pulverized particles of material over the upper surface of said mat; removably attaching dispersing means adapted to disperse said particles when contacting the same to form at least a pair of spaced paths of dispersed material to the head of said golf club, the overall weight of the club head before attaching the dispersing means thereto being only slightly less than the overall weight of the club head and dispersing means after attachment thereto; swinging said golf club head over said indicia on said mat; contacting said mat with said dispersing means thereby dispersing said particles into at least a pair of spaced elongated paths through said material dispersing the same in a pattern on all sides of said tracks; analyzing the pattern of said dispersed particles to determine the depth of swing of said golfer from the overall length of said dispersed particles, analyzing the arc of swing of said golfer from the relationship between the linear configuration of said dispersed particles and the indicia on said mat, and analyzing the angle of the face of said golf club head when said dispersing means contacted said mat from the pattern of dispersion of said dispersed particles.
Claim 2
Independent Claim
255 words
A method for analyzing both the depth and arc of swing of a golfer swinging a golf club head over a mat having indicia simulating golf ball thereon and analyzing the angle of the face of the golf club head when contacting said mat comprising the steps of: dispersing a relatively thin film of relatively soft fine dry pulverized particles of material over the upper surface of said mat; removably attaching dispersing means adapted to disperse said particles when contacting the same to form at least a pair of spaced paths of dispersed material to the head of said golf club, the overall weight of the club head before attaching the dispersing means thereto being only slightly less than the overall weight of the club head and dispersing means after attachment thereto; swinging said golf club head over said indicia on said mat; contacting said mat with said dispersing means thereby dispersing said particles into at least a pair of spaced elongated paths through said material dispersing the same in a pattern on all sides of said tracks; analyzing the pattern of said dispersed particles to determine the depth of swing of said golfer from the overall length of said dispersed particles, analyzing the arc of swing of said golfer from the relationship between the linear configuration of said dispersed particles and the indicia on said mat, and analyzing the angle of the face of said golf club head when said dispersing means contacted said mat from the pattern of dispersion of said dispersed particles.
Claim 3
Dependent Claim
144 words
In the method of claim 1 wherein said step of removably attaching the dispersing means includes the step of attaching dispersing means including a pair of downwardly extending spaced tracks having their longitudinal axes extending in a direction generally normal to the plane of the face of said golf club head to said golf club head, the overall distance between the outside of said tracks being substantially less than the diameter of said indicia; and the step of analyzing the angle of the face of said golf club head includes the step of comparing the difference in distinctiveness of the pattern dispersed material on the side of the path of the material dispersed by one of said tracks with the distinctiveness of the pattern of the dispersed material on the side of the path of the material dispersed by the other of said tracks.
Claim 4
Dependent Claim
182 words
In the method of claim 1 wherein said step of removably attaching dispersing means includes the step of attaching three downwardly extending spaced elements, two of said elements being linearly aligned along an axis extending generally normal to the plane of the face of said golf club head and the third of said elements being spaced from said two of said elements and generally equidistant from each of said two of said elements, the overall distance between the outside of said two of said elements being substantially less than the diameter of said indicia; and the step of analyzing the angle of the face of said head includes the step of comparing the difference between the spacing of the pattern of the dispersed material on the side of the path of the material dispersed by one of said two of said tracks and said third track with the difference between the spacing of the pattern of the dispersed material on the side of the path of the material dispersed by the other of said two of said tracks and said third track.
Claim 5
Dependent Claim
55 words
In the method of claim 1 further including the step of analyzing the equivalence of said golfer making a divot by comparing the distinctiveness of the patterns of the dispersed material at the beginning of the swing arc with the distinctiveness of the patterns of the dispersed material at the bottom of terminal end thereof.
