Abstract

Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head may include a body portion having a first interior cavity portion, a second interior cavity portion, a toe portion, a heel portion, a top portion, a bottom portion, a rear portion, a front portion, and a structural support portion formed in the bottom portion. The second interior cavity portion may include a filler material. Other examples and embodiments may be described and claimed.

Claims

1. A golf club head comprising:

a body portion comprising a top portion, a bottom portion, a toe portion, a heel portion, a front portion, and a rear portion;

a structural support portion formed in the bottom portion, the structural support portion comprising a groove portion extending between the toe portion and the heel portion more than 50% of a maximum toe-to-heel distance;

a first interior cavity portion within the body portion;

a second interior cavity portion defined by a recessed exterior surface of the bottom portion, the second interior cavity portion having a volume less than or equal to 25% of a volume of the body portion, the second interior cavity portion having a first side wall portion closer to the toe portion than the heel portion and a second side wall portion closer to the heel portion than the toe portion; and

an interchangeable insert disposed in the second interior cavity portion, the interchangeable insert comprising a filler material, the interchangeable insert extending from the first side wall portion of the second interior cavity portion to the second side wall portion of the second interior cavity portion,

wherein the interchangeable insert has a maximum thickness that is substantially equal to a maximum depth of the second interior cavity portion.

2. A golf club head as defined in claim 1 further comprising a bottom cover portion, wherein the bottom cover portion at least partially covers the interchangeable insert disposed in the second interior cavity portion.

3. A golf club head as defined in claim 1 further comprising a bottom cover portion and a fastener securing the bottom cover portion to the body portion, wherein the bottom cover portion and fastener together retain the interchangeable insert in the second interior cavity portion.

4. A golf club head as defined in claim 1, wherein the filler material comprises an elastic polymer material.

5. A golf club head comprising:

a body portion comprising a top portion, a bottom portion, a toe portion, a heel portion, a front portion, and a rear portion;

a structural support portion formed in the bottom portion, the structural support portion comprising a groove portion extending between the toe portion and the heel portion more than 50% of a maximum toe-to-heel distance;

a first interior cavity portion within the body portion; and

a second interior cavity portion defined by a recessed exterior surface of the bottom portion and located aft of the structural support portion, the second interior cavity portion having a first side wall portion closer to the toe portion than the heel portion and a second side wall portion closer to the heel portion than the toe portion, the second interior cavity portion comprising an interchangeable filler material, the interchangeable filler material extending from the first side wall portion of the second interior cavity portion to the second side wall portion of the second interior cavity portion,

wherein the interchangeable filler material has a maximum thickness that is substantially equal to a maximum depth of the second interior cavity portion.

6. A golf club head as defined in claim 5 further comprising a bottom cover portion at least partially covering the second interior cavity portion.

7. A golf club head as defined in claim 5 further comprising a bottom cover portion at least partially covering the second interior cavity, the bottom cover portion attached to the body portion by a fastening mechanism.

8. A golf club head as defined in claim 5, wherein a volume of the second interior cavity portion is 5% to 45% of a volume of the body portion.

9. A golf club head as defined in claim 5, wherein a volume of the second interior cavity portion is 5% to 25% of a volume of the body portion.

10. A golf club head as defined in claim 5, wherein a volume of the second interior cavity portion is 5% to 10% of a volume of the body portion.

11. A golf club head comprising:

a body portion comprising a top portion, a bottom portion, a toe portion, a heel portion, a front portion, and a rear portion;

a structural support portion formed in the bottom portion, the structural support portion comprising a groove portion extending between the toe portion and the heel portion more than 50% of a maximum toe-to-heel distance;

a first interior cavity portion within the body portion; and

a second interior cavity portion defined by a recessed exterior surface of the bottom portion and located at or near the rear portion and the bottom portion, the second interior cavity portion having a first side wall portion closer to the toe portion than the heel portion and a second side wall portion closer to the heel portion than the toe portion, the second interior cavity portion comprising an interchangeable filler material, the interchangeable filler material extending from the first side wall portion of the second interior cavity portion to the second side wall portion of the second interior cavity portion,

wherein the interchangeable filler material has a maximum thickness that is substantially equal to a maximum depth of the second interior cavity portion.

12. A golf club head as defined in claim 11, wherein the groove portion extends more than 60% of the maximum toe-to-heel distance.

13. A golf club head as defined in claim 11, wherein the groove portion extends more than 70% of the maximum toe-to-heel distance.

14. A golf club head as defined in claim 11, wherein the groove portion extends more than 80% of the maximum toe-to-heel distance.

15. A golf club head as defined in claim 11, wherein the groove portion extends more than 90% of the maximum toe-to-heel distance.

16. A golf club head as defined in claim 11, wherein a volume of the second interior cavity portion is 5% to 45% of a volume of the body portion.

17. A golf club head as defined in claim 11, wherein a volume of the second interior cavity portion is 5% to 35% of a volume of the body portion.

18. A golf club head as defined in claim 11, wherein a volume of the second interior cavity portion is 5% to 25% of a volume of the body portion.

19. A golf club head as defined in claim 11, wherein a volume of the second interior cavity portion is 5% to 10% of a volume of the body portion.

20. A golf club head as defined in claim 11, wherein the interchangeable filler material comprises a thermoplastic elastomer material.
