Abstract

A golf club with improved weighting characteristic is disclosed. More specifically, the present invention discloses to a golf club wherein the improved weighting distribution stems from an increase in the mass of the golf club at a specific distance away from the butt end or proximal end of the golf club head to help increase the feel and minimize the dispersion of the golf shot by minimizing the pull and or draw tendencies of a golf shot.

Claims

1. A golf club comprising:

a club head located at a distal end of said golf club;

a grip located at a proximal end of said golf club; and

a shaft juxtaposed between said club head and said grip, connecting said club head to said grip;

wherein said shaft further comprises a heavy weighted section, located at a distance of between exactly 10 and exactly 15 inches away from said proximal end of said golf club, and

wherein said heavy weighted section further comprises a dense layer, having a material density greater than a material density of said shaft, said dense layer is longitudinally located between an internal wall of said shaft and an external wall of said shaft from a beginning of said heavy weighted section to an end of said heavy weighted section.

2. The golf club of claim 1, wherein said dense layer only partially covers said heavy weighted section.

3. The golf club of claim 1, wherein said shaft further comprises a second lightweight section, located at a distance of between exactly 5 and exactly 10 inches away from said proximal end of said golf club head,

wherein said mass of said heavy weighted section is greater than about 140% of a mass of said second lightweight section.

4. The golf club of claim 3, wherein said mass of said heavy weight section is greater than about 145% of said mass of said second lightweight section.

5. The golf club of claim 4, wherein said mass of said heavy weight section is greater than about 150% of said mass of said second lightweight section.

6. The golf club head of claim 3, wherein said heavy weight section has a mass of greater than about 9 grams.

7. The golf club head of claim 3, wherein said heavy weight section has a mass of greater than about 9.5 grams.

8. The golf club head of claim 3, wherein said heavy weight section has a mass of greater than about 10 grams.

9. The golf club head of claim 6, wherein said dense layer is created using dense powder.

10. The golf club head of claim 6, wherein said dense layer is created using a thin layer of tungsten metal.

11. The golf club head of claim 6, wherein said dense layer is created using a thin layer of steel.

12. A golf club comprising:

a club head located at a distal end of said golf club;

a grip located at a proximal end of said golf club; and

a shaft juxtaposed between said club head and said grip, connecting said club head to said grip;

wherein said shaft further comprises a heavy weighted section, located at a distance of between exactly 10 and exactly 15 inches away from said proximal end of said golf club,

wherein said heavy weighted section further comprises a dense layer, having a material density greater than a material density of said shaft, said dense layer is located between an internal wall of said shaft and an external wall of said shaft, and

wherein said dense layer is created using dense powder.

13. The golf club head of claim 12, wherein said dense layer only partially covers said heavy weighted section.
