Abstract

A metal golf club head that allows a user to customize the location of the center of gravity. The metal golf club head comprises a hollow body with a weighting port. The weighting port allows a user to place weighting material inside the hollow body, customizing the location of the center of gravity, the swing weight, the total weight, and the balance of the golf club.

Claims

1. A golf club head comprising:

a relatively thin shell comprising a plurality of walls that collectively form a hollow body with a substantially empty or voided cavity, wherein one or more of said walls comprises a striking face configured to strike a golf ball;

a plurality of weights detachably secured to said shell of said club head, each of said plurality of weights being located at a readily user-accessible location along at least one wall of said shell for shifting said center of gravity of said golf club head relative to said striking face;

wherein said location of each of said plurality of weights is selected from a group of locations on said shell of said golf club head, comprising;

a first location near a rear of said club head, left of a center-line of said head;

a second location near said rear of said club head, right of said center-line of said head; and

a third location near the front of said club head; and

wherein repositioning of said plurality of weights between said first, second and third locations to shift said center of gravity of said golf club head relative to said striking face varies a tendency of a golf ball hit by said striking face to fly along generally fading, neutral and drawing trajectories.

2. A golf club head comprising:

a relatively thin shell comprising a plurality of walls that collectively form a hollow body with a substantially empty or voided cavity, wherein at least one of said walls comprises a striking face configured to strike a golf ball;

a plurality of weights detachably secured to said shell of said club head, each of said plurality of weights being located at a readily user-accessible location along said walls of said shell;

wherein said location of each of said plurality of weights is selected from a group of locations on said shell of said golf club head, comprising;

a first location near a rear of said club head, left of a center-line of said head; and

a second location near said rear of said club head, right of said center-line of said head;

each of said plurality of weights being accessible to a user, and each of said plurality of weights being detachable from, and detachably-securable to, said club head by said user for shifting said center of gravity of said golf club head relative to said striking face; and

wherein repositioning of said plurality of weights between said first and second locations at least varies a tendency of said golf club head to impart a drawing, neutral or fading trajectory to a golf ball hit by said striking face.

3. A golf club head comprising:

a relatively thin shell comprising a plurality of walls that collectively form a hollow body with a substantially empty or voided cavity, wherein at least one of said walls comprises a striking face configured to strike a golf ball;

a plurality of weights detachably secured to said shell of said club head, each of said plurality of weights being located in one of a plurality of spaced-apart, readily user-accessible locations along one or more walls of said shell; and

each of said plurality of weights being accessible to a user, and each of said plurality of weights being detachable from, and detachably-securable to, said club head by said user for shifting said center of gravity of said golf club head relative to said striking face to at least vary a tendency of said golf club head to impart a drawing, neutral or fading trajectory to a golf ball hit by said striking face.
