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 having a volume less than or equal to 25% of a volume of the body portion; and

an insert disposed in the second interior cavity portion, the insert comprising a filler material.

2. A golf club head as defined in claim 1, wherein the second interior cavity portion comprises a recessed portion in the bottom portion.

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

4. 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 second interior cavity portion defines a recessed portion in the bottom portion, and the bottom cover portion and the fastener together retain the insert in the recessed portion.

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

6. 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 located aft of the structural support portion, the second interior cavity portion comprising a filler material.

7. A golf club head as defined in claim 6, wherein the second interior cavity portion comprises a recessed portion in the bottom portion.

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

9. A golf club head as defined in claim 6 further comprising a bottom cover portion, wherein the second interior cavity portion comprises a recessed portion in the bottom portion, the bottom cover portion at least partially covering the recessed portion, the bottom cover portion attached to the body portion by a fastening mechanism.

10. 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 located at or near the rear portion and the bottom portion, the second interior cavity portion comprising a filler material.

11. A golf club head as defined in claim 10, wherein the groove portion extends more than 60% of the maximum toe-to-heel distance.

12. A golf club head as defined in claim 10, wherein the groove portion extends more than 70% of the maximum toe-to-heel distance.

13. A golf club head as defined in claim 10, wherein the groove portion extends more than 80% of the maximum toe-to-heel distance.

14. A golf club head as defined in claim 10, wherein the groove portion extends more than 90% of the maximum toe-to-heel distance.

15. A golf club head as defined in claim 10, wherein a volume of the second interior cavity portion is 5% to 45% of a volume of the body portion.

16. A golf club head as defined in claim 10, wherein a volume of the second interior cavity portion is 5% to 35% of a volume of the body portion.

17. A golf club head as defined in claim 10, wherein a volume of the second interior cavity portion is 5% to 25% of a volume of the body portion.

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