Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
103 words
A method of training oneself to properly swing a golf club comprising the steps of: (A) providing a golf swing training device comprising a pair of training sticks, separate and independently movable relative to one another, each of said training sticks having a shaft having upper and lower ends, a weight, and flexible elongate means of fixed length connecting said lower end of said shaft and said weight; and (B) practicing movements associated with a golf swing while swinging the training sticks in a prescribed pattern of exercise with each hand holding a different one of the shafts by an upper end thereof.
Claim 2
Independent Claim
103 words
A method of training oneself to properly swing a golf club comprising the steps of: (A) providing a golf swing training device comprising a pair of training sticks, separate and independently movable relative to one another, each of said training sticks having a shaft having upper and lower ends, a weight, and flexible elongate means of fixed length connecting said lower end of said shaft and said weight; and (B) practicing movements associated with a golf swing while swinging the training sticks in a prescribed pattern of exercise with each hand holding a different one of the shafts by an upper end thereof.
Claim 3
Dependent Claim
12 words
The method of claim 1 wherein said elongate means comprises a cable.
Claim 4
Dependent Claim
21 words
The method of claim 1 wherein the length of said elongate means is short relative to the length of said shaft.
Claim 5
Dependent Claim
50 words
The method of claim 1 wherein said weight has upper and lower portions and said elongate means connects said shaft lower end and said weight upper portion so that the maximum separation of said shaft upper end and said weight lower portion is less than about 58 cms (23 ins.).
Claim 6
Dependent Claim
15 words
The method of claim 1 wherein each said weight is about 94 gms. (0.37 lbs.).
Claim 7
Dependent Claim
17 words
The method of claim 1 wherein each said weight is about 6.4 cms (2.5 ins.) in diameter.
Claim 8
Dependent Claim
21 words
The method of claim 1 wherein said shaft comprises about 74% by weight of said device, and said weight about 22%.
Claim 9
Dependent Claim
29 words
The method of claim 7 wherein the device also includes means for connecting said shafts at a selected point along their length to limit separation therebetween at said points.
Claim 10
Dependent Claim
11 words
The method of claim 8 wherein said connecting means is flexible.
Claim 11
Dependent Claim
14 words
The method of claim 8 wherein said connecting means connects said shaft upper ends.
Claim 12
Dependent Claim
20 words
The method of claim 8 wherein said connecting means provides a variable maximum separation between said shafts at said points.
Claim 13
Dependent Claim
16 words
The method of claim 10 wherein said variable maximum separation is about 7.6-25.4 cms (3-10 ins.)
Claim 14
Dependent Claim
32 words
The method of claim 8 wherein each of said shaft upper ends defines attachment means, and said connecting means comprises a non-stretchable means of variable effective length for interconnecting said attachment means.
Claim 15
Dependent Claim
22 words
The method of claim 8 wherein said connecting means enables said shafts to be held by a spaced pair of back-to-back hands.
Claim 16
Dependent Claim
22 words
The method of claim 8 wherein said connecting means enables said shafts to be held by a spaced pair of palm-to-palm hands.
Claim 17
Dependent Claim
51 words
The method of claim 1 wherein said training sticks are configured and dimensioned such that in certain training exercises an improper swing is evidenced by a non-parallel relation between said training sticks during a swing and a proper swing is evidenced by a parallel relation between said shafts during a swing.
Claim 18
Dependent Claim
43 words
The method of claim 1 wherein said elongate means is configured and dimensioned such that in certain training exercises an improper swing is evidenced by said weight leading the wrists on the down stroke, whereby control of the stick is rendered more difficult.
Claim 19
Dependent Claim
22 words
The method of claim 1 wherein in step (B) the shafts are held with the hands in a crossed generally back-to-back relation.
Claim 20
Dependent Claim
22 words
The method of claim 1 wherein in step (B) the shafts are held with the hands in a non-crossed generally palm-to-palm relation.
Claim 21
Dependent Claim
51 words
The method of claim 1 wherein the device includes means for connecting the shafts, each at a selected point along its length to variably limit separation therebetween at the points, and step (A) includes adjusting the connecting means to provide the desired limit on separation between the shafts at the points.
Claim 22
Dependent Claim
62 words
The method of claim 20 wherein in step (B) the shafts are held with the hands in a crossed generally back-to-back relation, and the user swings the training sticks together while maintaining the shafts as close to parallel as possible during the swing and a non-parallel relation between the shafts during the swing evidences that one hand or the other is dominating.
Claim 23
Dependent Claim
29 words
The method of claim 20 including the step of connecting the shafts with the connecting means at the upper ends thereof to limit separation therebetween at the upper ends.
Claim 24
Dependent Claim
47 words
The method of claim 1 wherein the user swings the training sticks separately while maintaining his wrist, the shaft and the weight aligned during each down swing as much as possible and the weight moving ahead of the shaft and wrist with a jerking motion evidences casting.
Claim 25
Dependent Claim
28 words
The method of claim 1 wherein the prescribed pattern of exercise causes the orientation of the training sticks during the practice swings to evidence an improper practice swing.
