Abstract

A golf club head comprising a body and a plurality of carbon tubes is disclosed herein. The body comprises a face section, a sole section with a protrusion extending upward and a crown section. The body defines a hollow interior. Each of the plurality of carbon tubes extends from the crown section to the protrusion of the sole section.

First claim

We claim as our invention the following:

1. A golf club head comprising:
a body comprising a sole section, a crown section, a front section having an opening, and an elongated protrusion extending upward from the sole section and towards the front section and extending from a heel side of the body to a toe side of the body;
a face component positioned over the opening, the face component comprising a striking plate; and
a plurality of carbon tubes,
wherein the plurality of carbon tubes ranges from two carbon tubes to eight carbon tubes,
wherein each of the plurality of carbon tubes is disposed within a hollow interior of the body and extends from the crown section to the elongated protrusion,
wherein the crown section comprises a plurality of crown apertures, each of the plurality of crown apertures corresponding to a carbon tube of the plurality carbon tubes,
wherein the elongated protrusion of the sole section comprises a plurality of bosses, each of the plurality of bosses corresponding to a carbon tube of the plurality carbon tubes,
wherein each of the plurality of bosses extends upwards from an upper surface of the elongated protrusion, and
wherein each of the plurality of carbon tubes is located within 11 millimeters of an interior surface of the striking plate.

2. The golf club head according to claim 1 , wherein each of the plurality of carbon tubes has a diameter ranging from 2 millimeters to 5 millimeters.

3. The golf club head according to claim 1 , wherein each of the plurality of carbon tubes has a length ranging from 30 millimeters to 60 millimeters.

4. The golf club head according to claim 1 , wherein the golf club head has a volume ranging from 100 cubic centimeters to 300 cubic centimeters.

5. The golf club head according to claim 1 , wherein each of the plurality of carbon tubes is positioned rearward from the interior surface a distance ranging from 2 millimeters to 11 millimeters.

6. The golf club head according to claim 1 , wherein the body is composed of an iron alloy.

7. A fairway wood-type golf club head comprising:
a body comprising a crown section, a front section having an opening, and a sole section having an elongated protrusion extending from a heel side of the body to a toe side of the body and upward and forward towards the front section, the body composed of a first metal material;
a face component composed of a second metal material positioned over the opening, the face component comprising a striking plate portion and a return portion that extends substantially perpendicular to the striking plate portion; and
a plurality of carbon tubes, each of the plurality of carbon tubes disposed within a hollow interior of the body and extending from the crown section to the elongated protrusion,
wherein the plurality of carbon tubes ranges from two carbon tubes to eight carbon tubes,
wherein each of the plurality of carbon tubes is located within 11 millimeters of an interior surface of the striking plate portion,
wherein the crown section comprises a plurality of crown apertures, each of the plurality of crown apertures corresponding to a carbon tube of the plurality carbon tubes,
wherein the first metal material is different from the second metal material,
wherein the elongated protrusion of the sole section comprises a plurality of bosses,
wherein each of the plurality of bosses extends from an upper surface of the elongated protrusion, and
wherein each of the plurality of bosses corresponds to a carbon tube of the plurality carbon tubes.

8. The fairway wood-type golf club head according to claim 7 , wherein the elongated protrusion comprises a base section and an extension section, and wherein the extension section extends above an internal surface of the sole section and toward the striking plate portion.

9. The fairway wood-type golf club head according to claim 7 , wherein each of the plurality of carbon tubes has a diameter ranging from 2 millimeters to 5 millimeters.

10. The fairway wood-type golf club head according to claim 7 , wherein each of the plurality of carbon tubes has a length ranging from 30 millimeters to 60 millimeters.

11. The fairway wood-type golf club head according to claim 7 , wherein the golf club head has a volume ranging from 100 cubic centimeters to 300 cubic centimeters.

12. The fairway wood-type golf club head according to claim 7 , wherein each of the plurality of carbon tubes is positioned rearward from an interior surface of the striking plate portion a distance ranging from 2 millimeters to 11 millimeters.

13. The fairway wood-type golf club head according to claim 7 , wherein the body is composed of a titanium alloy.

14. The fairway wood-type golf club head according to claim 7 , wherein the body is composed of an iron alloy.

15. A golf club head comprising:
a body comprising a sole section, a crown section having a plurality of crown of apertures, a hollow interior, a front section having an opening in communication with the hollow interior, and an elongated protrusion extending from a heel side of the body to a toe side of the body within the hollow interior, the elongated protrusion extending upward from the sole section towards the front section;
a face component positioned over the opening, the face component comprising a striking plate portion and a return portion extending substantially perpendicular to the striking plate portion; and
a plurality of carbon tubes,
wherein the elongated protrusion comprises a base section and an extension section,
wherein the extension section extends above an internal surface of the sole section and toward the striking plate portion without making contact with the striking plate portion,
wherein each of the plurality of carbon tubes is disposed within the hollow interior and extends from the crown section to connect with the extension section of the elongated protrusion,
wherein the elongated protrusion comprises at least 20% of an overall mass of the body,
wherein the golf club head has a volume ranging from 100 cubic centimeters to 300 cubic centimeters and a mass ranging from 135 grams to 200 grams,
wherein the face component is welded to the body,
wherein the plurality of carbon tubes ranges from two carbon tubes to eight carbon tubes,
wherein each of the plurality of carbon tubes is positioned rearward from an interior surface of the striking face portion a distance ranging from 2 millimeters to 11 millimeters, and
wherein each of the plurality of crown apertures corresponds to a carbon tube of the plurality carbon tubes.
