Abstract

A golf club head comprising a body, an elevated weight bar, and a plurality of carbon tubes is disclosed herein. The body comprises a hollow interior, a face section, a sole section, and a crown section, and the elevated weight bar bridges at least a portion of the sole and may be formed separately from the rest of the body and then affixed to the body by welding or a mechanical fastener. In one embodiment, each of the carbon tubes extends from the crown section and terminates at the elevated weight bar, while in another embodiment each of the carbon tubes extends from the crown section to the sole section and passes through the elevated weight bar without making contact with the floating weight bar.

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, a hollow interior, and an elevated weight bar extending from a heel side of the sole section to a toe side of the sole section and bridging a central area of the sole section;
a face component positioned over the opening; and
a plurality of carbon tubes, each of the plurality of carbon tubes extending from the crown section to the sole section,
wherein the elevated weight bar comprises a plurality of through-bores,
wherein each of the plurality of carbon tubes extends through one of the plurality of through-bores to contact the sole section, and
wherein the elevated weight bar and each of the plurality of carbon tubes are disposed within the hollow interior proximate the front section.

2. The golf club head according to claim 1 , wherein the elevated weight bar is formed separately from the body.

3. The golf club head according to claim 2 , wherein the elevated weight bar is welded to the sole section.

4. The golf club head according to claim 1 , wherein the crown section comprises a first plurality of apertures, wherein each of the first plurality of apertures corresponds to a carbon tube of the plurality carbon tubes, wherein the sole section comprises a second plurality of apertures, and wherein each of the second plurality of apertures corresponds to a carbon tube of the plurality carbon tubes.

5. The golf club head according to claim 1 , wherein none of the plurality of carbon tubes contacts the elevated weight bar.

6. The golf club head according to claim 1 , wherein the face component comprises at least one return section and a striking plate section, and wherein each of the plurality of carbon tubes is within 11 millimeters of an interior surface of the striking plate section.

7. The golf club head according to claim 1 , further comprising a plurality of bosses, wherein each of the plurality of bosses corresponds to an aperture of the first and second pluralities of apertures.

8. The golf club head according to claim 1 , wherein the golf club head is a wood-type golf club head.

9. The golf club head according to claim 1 , wherein each of the plurality of carbon tubes is spaced a distance of at least 12 millimeters and no more than 25 millimeters from an adjacent carbon tube.

10. A fairway wood-type golf club head comprising:
a steel body comprising a sole section, a crown section, a front section having an opening, a hollow interior, and an elevated weight bar extending from a heel side of the sole section to a toe side of the sole section and bridging a central area of the sole section;
a steel face component positioned over the opening, the face component comprising a striking plate section and at least one return section; and
at least three carbon tubes, each of the carbon tubes extending from the crown section to the sole section and positioned rearward from an interior surface of the striking plate section a distance of no less than 2 millimeters and no more than 11 millimeters,
wherein the elevated weight bar comprises at least three through-bores,
wherein each of the carbon tubes extends through one of the through-bores to contact the sole section,
wherein none of the carbon tubes contacts the elevated weight bar,
wherein the elevated weight bar and each of the plurality of carbon tubes are disposed within the hollow interior proximate the front section, and
wherein the elevated weight bar is welded to the sole section.
