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 hollow body portion having a front portion, a rear portion, a toe portion, a heel portion, a bottom portion, a top portion, a plurality of ports in the bottom portion, and an elastic polymer insert in contact with the inner surface of the bottom portion. Other examples and embodiments may be described and claimed.

Claims

1. A golf club head comprising:

a hollow body portion having a front portion, a rear portion, a toe portion, a heel portion, a top portion, and a bottom portion having an inner surface and an outer surface;

a plurality of ports in the bottom portion, the plurality of ports extending from the outer surface of the bottom portion toward the top portion, the plurality of ports comprising a first plurality of ports and a second plurality of ports, wherein the first plurality of ports are closer to the rear portion than the front portion, and the second plurality of ports are closer to the front portion than the rear portion; and

an elastic polymer insert in contact with the inner surface of the bottom portion, the elastic polymer insert extending from the inner surface of the bottom portion toward the top portion, the elastic polymer insert surrounding the plurality of ports.

2. A golf club head as defined in claim 1, wherein the second plurality of ports extends more than 50% of a maximum toe-to-heel distance between the toe portion and the heel portion.

3. A golf club head as defined in claim 1, the elastic polymer insert comprising a plurality of cutout portions, wherein each port of the plurality of ports is substantially aligned with one of the plurality of cutout portions.

4. A golf club head as defined in claim 1 further comprising a continuous inner wall portion extending from the inner surface of the bottom portion toward the top portion, the inner wall portion surrounding the plurality of ports.

5. A golf club head as defined in claim 1, wherein the elastic polymer insert comprises a thermoplastic elastomer.

6. A golf club head as defined in claim 1, wherein the elastic polymer insert is attached to the inner surface of the bottom portion with an epoxy.

7. A golf club head as defined in claim 1, wherein the elastic polymer insert is attached to the inner surface of the bottom portion with a solvent-based solution.

8. A golf club head comprising:

a hollow body portion having a front portion, a rear portion, a toe portion, a heel portion, a top portion, and a bottom portion having an inner surface and an outer surface;

a plurality of ports in the bottom portion, the plurality of ports extending from the outer surface of the bottom portion toward the top portion, the plurality of ports comprising a first plurality of ports and a second plurality of ports, wherein the second plurality of ports extends more than 50% of a maximum toe-to-heel distance between the toe portion and the heel portion; and

an elastic polymer insert in contact with the inner surface of the bottom portion, the elastic polymer insert extending from the inner surface of the bottom portion toward the top portion, the elastic polymer insert surrounding the plurality of ports.

9. A golf club head as defined in claim 8 further comprising:

an inner port region on the inner surface of the bottom portion, the plurality of ports located within the inner port region; and

an inner support portion extending from the inner surface of the bottom portion toward the top portion and surrounding the inner port region.

10. A golf club head as defined in claim 8, wherein the elastic polymer insert comprises a plurality of hexagonal recesses in a honeycomb configuration.

11. A golf club head as defined in claim 8, wherein the elastic polymer insert is attached to the inner surface of the bottom portion with a bonding portion.

12. A golf club head as defined in claim 8 further comprising a continuous inner wall portion extending from the inner surface of the bottom portion toward the top portion, the inner wall portion surrounding the plurality of ports.

13. A golf club head as defined in claim 8 further comprising an outer support portion defined by an indentation in the bottom portion extending on the outer surface of the bottom portion between the front portion and the rear portion.

14. A golf club head comprising:

a hollow body portion having a front portion, a rear portion, a toe portion, a heel portion, a top portion, and a bottom portion having an inner surface and an outer surface;

a plurality of ports in the bottom portion, the plurality of ports extending from the outer surface of the bottom portion toward the top portion, the plurality of ports comprising a first plurality of ports and a second plurality of ports; and

an elastic polymer insert in contact with the inner surface of the bottom portion, the elastic polymer insert extending from the inner surface of the bottom portion toward the top portion, the elastic polymer insert surrounding the plurality of ports.

15. A golf club head as defined in claim 14 further comprising a continuous inner wall portion extending from the inner surface of the bottom portion toward the top portion, the inner wall portion surrounding the plurality of ports.

16. A golf club head as defined in claim 14 further comprising an inner support portion extending from the inner surface of the bottom portion toward the top portion, the inner support portion located between the plurality of the ports and a periphery of the body portion.

17. A golf club head as defined in claim 14 further comprising an outer support portion on the bottom portion, the outer support portion located between the plurality of the ports and a periphery of the body portion.

18. A golf club head as defined in claim 14 further comprising a plurality of weight portions, one of the plurality of weight portions disposed in each of the plurality of ports.

19. A golf club head as defined in claim 14 further comprising:
