Abstract

A golf club, the body of the club head is constructed from a first material and has a center of gravity and is adapted to receive a weight member, at least one weight member constructed from a second material having a density greater than that of the first material, the weight member having a center of gravity and is securely received in the club head body in a manner so that the center of gravity of the weight member is positioned below the center of gravity of the club head body.

Claims

1. A club head for a golf club, the club head comprising:

a) a body, said body constructed from a first material and having a center of gravity, said body configured to receive a weight member; and

b) at least one weight member, said at least one weight member constructed from a second material having a density greater than that of said first material, said at least one weight member having a center of gravity and received in said body so that the center of gravity of said at least one weight member is positioned below the center of gravity of said club head body.

2. A club head as in claim 1 and wherein:

a) said body having an elongated configuration terminating at opposite ends thereof and having a longitudinal central axis extending therethrough, said at least one weight member received in said body is aligned along the central axis and extends transverse thereto.

3. A club head as in claim 2 and further including:

a) a second weight member, said second weight member received in said body and aligned along the central axis and extending transverse thereto.

4. A club head as in claim 2 and wherein:

a) each of said at least one weight member and said second weight member are received in said body adjacent to a separate one of said opposite ends thereof.

5. A club head as in claim 3 and further including;

a) a pair bores extending into said body, each of said pair of bores for receiving a separate one of said at least one weight member and said second weight member.

6. A club head as in claim 1 and wherein:

a) each of said first and second materials are selected from a group consisting of metal materials and synthetic materials.

7. A club head as in claim 6 and wherein:

a) said metal materials are selected from the group consisting of aluminum and brass.

8. A club head as in claim 7 and wherein:

a) said synthetic materials are selected from the group consisting of plastic materials and composite materials.

9. A club head as in claim 5 and wherein:

a) said pair of bores are cylindrically shaped and said at least one weight member and said second weight member are shaped to be fixedly received within a separate one of each of said pair of bores.

10. A club head as in claim 2 and wherein:

a) said at least one weight member is disposed beneath the longitudinally extending central axis of said body.

11. A club head as in claim 1 and further including:

a) a passage, said passage extending into said body and configured to receive an end of a golf club shaft.

12. A club head as in claim 2 and wherein:

a) said body is tapered toward each of said opposite ends thereof.

13. A club head as in claim 5 and wherein:

a) each of said at least one weight member and said second weight member are fixedly secured into a separate one of said pair bores.

15. A golf club as in claim 14 and wherein:

a) said body having an elongated configuration terminating at opposite ends thereof and having a longitudinal central axis extending therethrough, said at least one weight member received in said body is aligned along the central axis and extends transverse thereto.

16. A golf club as in claim 15 and further including:

a) a second weight member, said second weight member received in said body and aligned along the central axis and extending transverse thereto.

17. A golf club as in claim 16 and wherein:

a) each of said at least one weight member and said second weight member are received in said body adjacent to a separate one of said opposite ends thereof.

18. A golf club as in claim 16 and further including;

a) a pair bores extending into said body, each of said pair of bores for receiving a separate one of said at least one weight member and said second weight member.

19. A golf club as in claim 18 and wherein:

a) said pair of bores are cylindrically shaped and said at least one weight member and said second weight member are shaped to be fixedly received within a separate one of each of said pair of bores.

20. A golf club as in claim 15 and wherein:

a) said at least one weight member is disposed beneath the longitudinally extending central axis of said body.

14. A golf club comprising:

a) a shaft, said shaft having a gripping portion at one end thereof and a lower portion at an opposite end thereof, said lower portion configured to receive a club head;

b) a club head secured to said opposite end of said shaft, said club head comprising a body constructed from a first material and having a center of gravity, said body configured to receive a weight member; and

c) at least one weight member, said at least one weight member constructed from a second material having a density greater than that of said first material, said at least one weight member having a center of gravity and received in said body so that the center of gravity of said at least one weight member is positioned below the center of gravity of said club head body.
