Abstract

A putter-type golf club head is disclosed. When oriented in a reference position, the putter-type golf club head comprises a blade member and a central elongate member in communication with, and extending rearwardly from, the blade member. The blade member extends in a heel-to-toe direction and has a striking wall defining a substantially planar striking surface, and an upper surface of the central elongate member comprises at least one generally square-shaped alignment element.

Claims

1. A putter-type golf club head that, when oriented in a reference position, comprises:

a main body comprising a blade member extending in a heel-to-toe direction and having a striking wall defining a substantially planar striking surface, and a central elongate member in communication with, and extending rearwardly from, the blade member, the central elongate member having an upper surface;

wherein;

the main body is formed of plural discrete components including a sole portion comprising a first material and a top portion comprising a second material different from the first material; and

the upper surface of the central elongate member comprising at least one generally square-shaped alignment element.

2. The putter-type golf club head of claim 1, wherein the sole portion is secured to the top portion by a mechanical fastener.

3. The putter-type golf club head of claim 1, wherein the first material comprises a first density and the second material comprises a second density that is less than the first density.

4. The putter-type golf club head of claim 1, further comprising a resilient material sandwiched between the sole portion and the top portion.

5. The putter-type golf club head of claim 1, wherein the first material comprises stainless steel and the second material comprises aluminum.

6. The putter-type golf club head of claim 1, wherein the first material is harder than the second material.

7. The putter-type golf club head of claim 1, wherein the main body is substantially T-shaped.

8. The putter-type golf club head of claim 1, wherein:

the central elongate member further comprises a width, in the heel-to-toe direction, that is greater than a diameter of a conventional golf ball; and

the at least one alignment element comprises a width, in the heel-to-toe direction, that is slightly less than the diameter of the conventional golf ball.

9. The putter-type golf club head of claim 1, wherein the club head is face-balanced.

10. A putter-type golf club head that, when oriented in a reference position, comprises:

a blade member extending in a heel-to-toe direction and having a striking wall defining a substantially planar striking surface;

a central elongate member in communication with, and extending rearwardly from, the blade member, the central elongate member comprising an upper surface having at least one generally square-shaped alignment element;

a cantilevered heel arm extending rearward from a heel-ward portion of the blade member; and

a cantilevered toe arm extending rearward from a toe-ward portion of the blade member.

11. The putter-type golf club head of claim 10, further comprising:

a heel-ward gap defined between the heel arm and the central elongate member, the heel-ward gap having a first bend; and

a toe-ward gap defined between the toe arm and the central elongate member, the toe-ward gap having a second bend.

12. The putter-type golf club head of claim 10, wherein at least one of the heel arm and the toe arm tapers in thickness in the front-to-rear direction.

13. The putter-type golf club head of claim 10, wherein the at least one generally square-shaped alignment element comprises at least two generally square-shaped alignment elements.

14. The putter-type golf club head of claim 10, wherein:

the central elongate member further comprises a width, in the heel-to-toe direction, that is greater than a diameter of a conventional golf ball; and

the at least one alignment element comprises a width, in the heel-to-toe direction, that is slightly less than the diameter of the conventional golf ball.

15. The putter-type golf club head of claim 10, wherein the club head is face-balanced.

16. A putter-type golf club head that, when oriented in a reference position, comprises:

a blade member extending in a heel-to-toe direction and having a striking wall defining a substantially planar striking surface;

a central elongate member in communication with, and extending rearwardly from, the blade member, the central elongate member comprising an upper surface having at least one generally square-shaped alignment element;

a cantilevered heel arm secured to a rear portion of the central elongate member and projecting heel-wardly and forwardly of the rear portion; and

a cantilevered toe arm secured to a toe-ward side of the rear portion of the central elongate member and projecting toe-wardly and forwardly of the rear portion.

17. The putter-type golf club head of claim 16, wherein the at least one generally square-shaped alignment element comprises at least two generally square-shaped alignment elements.

18. The putter-type golf club head of claim 16, wherein:

the central elongate member further comprises a width, in the heel-to-toe direction, that is greater than a diameter of a conventional golf ball; and

the at least one alignment element comprises a width, in the heel-to-toe direction, that is slightly less than the diameter of the conventional golf ball.

19. The putter-type golf club head of claim 16, wherein the club head is face-balanced.

20. The putter-type golf club head of claim 16, wherein the heel arm and the toe arm are formed in a unitary sole portion, and the central elongate member is formed in a unitary top portion discrete from the sole portion, wherein the sole portion is mechanically coupled to the top portion.
