7 . The driver of claim 1 , wherein said club head weighs approximately 240 grams and said shaft weighs approximately 175 grams.
8 . The driver of claim 1 , wherein said ratio of a weight of said club head to a weight of said shaft comprises less than 1.2.
9 . The driver of claim 1 , further comprising a grip, said grip coupled to said shaft at said butt end of said shaft.
10 . The driver of claim 1 , wherein said club head comprises one or more of aluminum, titanium, and stainless steel, and said shaft comprises one or more of steel and a steel alloy.
11 . The driver of claim 1 , wherein the combined weight of said club head and said shaft is greater than approximately 400 grams.
12 . The driver of claim 1 , further comprising a weight attached to an inside surface of the hollow club head.
13 . A golf club driver comprising:
a substantially hollow club head; and a shaft, said shaft comprising a butt end and a tip end, and said shaft further comprising a hollow longitudinal axis; wherein said club head is coupled to said tip end of said shaft; and wherein said club head comprises walls wherein a thickness of said walls ranges from approximately 1.6 mm to approximately 6.2 mm.
14 . The driver of claim 13 ,
wherein a front face of said club head ranges in thickness from approximately 5 mm to approximately 6.2 mm; wherein a top surface of said club head ranges in thickness from approximately 1.6 mm to approximately 2.9 mm; and wherein a bottom surface of said club head ranges in thickness from approximately 2.3 mm to approximately 3 mm.
15 . The driver of claim 13 ,
wherein the inside diameter of said tip end of said shaft ranges from approximately 0.25 mm to approximately 0.27 mm; wherein the outside diameter of said tip end of said shaft ranges from approximately 0.33 mm to approximately 0.34 mm; wherein the thickness of the shaft wall at said tip end ranges from approximately 0.066 mm to approximately 0.088 mm; wherein the inside diameter of said butt end of said shaft ranges from approximately 0.53 mm to approximately 0.57 mm; wherein the outside diameter of said butt end of said shaft ranges from approximately 0.58 mm to approximately 0.60 mm; and wherein the thickness of the shaft wall at said butt end ranges from approximately 0.044 mm to approximately 0.063 mm.
16 . The driver of claim 13 , wherein said shaft comprises a plurality of sections, each section comprising a different inside and outer diameter.
17 . The driver of claim 13 , further comprising a grip, said grip coupled to said butt end of said shaft.
18 . The driver of claim 13 , wherein said club head comprises one or more of aluminum, titanium, and stainless steel, and said shaft comprises one or more of steel and a steel alloy.
19 . A golf club driver comprising:
a substantially hollow club head; and a shaft, said shaft comprising a butt end and a tip end; wherein said club head is coupled to the tip end of said shaft; wherein said club head ranges in weight from approximately 240 grams to approximately 450 grams; and wherein said shaft ranges in weight from approximately 175 grams to approximately 250 grams.
20 . The driver of claim 19 , wherein a ratio of a weight of said club head to a weight of said shaft comprises a range of approximately 1.2 to 1.6.
21 . The driver of claim 19 , wherein said club head comprises one or more of aluminum, titanium, and stainless steel, and said shaft comprises one or more of steel and a steel alloy.
22 . The golf club driver of claim 19 , wherein the weights of said club head and said shaft perfect the timing of the release of said club head when said driver is swung by a golfer.Cited by (0)
