Golf club head with hosel support structure
A golf club head having a hosel, a hollow interior, and a support structure disposed within the hollow interior proximate a flange region is disclosed herein. In particular, the present invention is directed to a fairway wood head comprising a body with a front wall, an upper opening, a return portion between the front wall and the upper opening, a hosel, an interface between the hosel and the heel side of the body, and a hosel support ring or support rod, and a composite crown affixed to the body to close the upper opening and define a hollow interior. The support structure reduces the stresses placed on, for example, the crown during hosel bending processes.
1. A golf club head comprising:
a body comprising a sole, a heel side, a toe side, a front wall, a rear side opposite the front wall, a return portion extending away from the front wall towards the rear side, a front opening in the front wall, a hollow interior, and an upper opening;
a hosel connected to the body at the heel side, the hosel comprising a tube portion and a shaft receiving bore;
a face component affixed to the body to close the front opening;
a flange region defined as an interface between the tube portion and the body;
a crown affixed to the body to close the upper opening and enclose the hollow interior; and
a support rod disposed within the hollow interior,
wherein the support rod extends from the sole to the return portion proximate the flange region,
wherein the support rod is disposed entirely behind the hosel along a horizontal, front-to rear x-axis, and heel-ward of a vertical xz plane extending through a heel-most side of the front opening, wherein the z-axis is in a vertical, sole to top direction.
2. The golf club head of claim 1 , further comprising a bond flange, wherein the bond flange encircles the upper opening.
3. The golf club head of claim 1 , wherein the golf club head is selected from the group consisting of a fairway wood, a driver, and a hybrid.
4. The golf club head of claim 1 , wherein the body is composed of a first material having a first density, wherein the hosel is composed of a second material having a second density, wherein the crown is composed of a third material having a third density, and wherein the first density is greater than the second density and the third density.
5. The golf club head of claim 4 , wherein the first material is a metal alloy, and wherein the third material is carbon composite.
6. The golf club head of claim 5 , wherein the second material is an aluminum alloy.
7. The golf club head of claim 1 , wherein the support rod is integrally cast with the body.
8. The golf club head of claim 7 , wherein the hosel is integrally cast with the body.
9. The golf club head of claim 1 , wherein the body is composed of a first material having a first density, wherein the support rod is composed of a second material having a second density, and wherein the first density is greater than the second density.
10. The golf club head of claim 1 , wherein the body is integrally cast with the hosel and the support rod from a material selected from the group consisting of titanium alloy and steel, and wherein the crown is composed of a carbon composite material.
11. The golf club head of claim 1 , wherein the golf club head has a volume of 50 to 250 cubic centimeters.
12. The golf club head of claim 1 , further comprising at least one of a weight port and a weight lip.
13. The golf club head of claim 12 , wherein the golf club head comprises two weight ports and a weight lip.
14. A wood-type golf club head comprising:
a cast metal body comprising a sole, a heel side, a toe side, a front wall, a rear side opposite the front wall, a return portion extending away from the front wall towards the rear side, an upper opening, a front opening in the front wall, a hosel, a flange region, a support rod, and a volume of 50-250 cubic centimeters;
a face component affixed to the body to close the front opening; and
a carbon composite crown affixed to the body to close the upper opening and define a hollow interior,
wherein the flange region is defined as an interface between the hosel and the rest of the body,
wherein the support rod is contained within the hollow interior proximate the flange region and extends from the sole to the return portion approximately parallel with the front wall, and
wherein the support rod is disposed entirely behind the hosel along a horizontal, front-to rear x-axis, and heel-ward of a vertical xz plane extending through a heel-most side of the front opening, wherein the z-axis is in a vertical, sole to top direction.
15. The wood-type golf club head of claim 14 , further comprising a bond flange, wherein the bond flange encircles the upper opening, and wherein the crown is permanently affixed to an exterior surface of the bond flange with an adhesive material.
16. The wood-type golf club head of claim 14 , further comprising at least one of a weight port and a weight lip.
17. The wood-type golf club head of claim 16 , wherein the golf club head comprises two weight ports and a weight lip.
