Golf club head with hosel support structure
A golf club head having a hosel, a hollow interior, and a support ring disposed within the hollow interior and at least partially encircling the hosel 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 support ring, and a composite crown affixed to the body to close the upper opening and define a hollow interior, the support ring contained within the hollow interior and extending along the interface from a heel-most side of the body to the return portion and making contact with an inner surface of the front wall. The support ring reduces the stresses placed on, for example, the crown during hosel bending processes.

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, 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 flange region defined as an interface between the tube portion and the body;
a crown sized affixed to the body to close the upper opening and define a hollow interior; and
a support ring disposed within the hollow interior, wherein the support ring is integrally cast with the body,
wherein the support ring extends along the flange region from the heel side to the return portion, and
wherein the support ring contacts an inner surface of the front wall.
2. The golf club head of claim 1 , further comprising a face component, wherein the front wall comprises a front opening, and wherein the face component is affixed to the body to cover the front opening.
3. The golf club head of claim 1 , further comprising a bond flange, wherein the bond flange encircles the upper opening.
4. 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.
5. 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.
6. The golf club head of claim 5 , wherein the first material is a metal alloy, and wherein the third material is carbon composite.
7. The golf club head of claim 6 , wherein the second material is an aluminum alloy.
8. The golf club head of claim 1 , wherein the hosel is integrally cast with the body.
9. The golf club head of claim 1 , wherein the support ring has a length of approximately 0.125 inch and a thickness of approximately 0.060 inch.
10. The golf club head of claim 1 , wherein the body is integrally cast with the hosel and the support ring 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. 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 hosel, a flange region, a support ring, and a volume of 50-250 cubic centimeters; 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 ring is contained within the hollow interior and extends along the flange region from the heel side to the return portion, and
wherein the support ring has a maximum length of at least 0.050 inch and a maximum thickness of at least 0.010 inch.
13. The wood-type golf club head of claim 12 , 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.
14. The wood-type golf club head of claim 12 , wherein the support ring has a length of approximately 0.125 inch and a thickness of approximately 0.060 inch.
15. The wood-type golf club head of claim 12 , wherein the support ring contacts an inner surface of the front wall.
16. A fairway wood-type golf club head comprising:
a cast metal body comprising a front wall with a front opening, a rear side opposite the front wall, a heel side, a toe side, a sole extending away from a lower edge of the front wall towards the rear side, a return portion extending away from an upper edge of the front wall towards the rear side, an upper opening disposed between the rear side and the return portion, a bond flange encircling the upper opening, a hosel, a hosel flange region, and a support ring;
a face component affixed to the body to cover the front opening; and
a carbon composite crown affixed to an exterior surface of the bond flange to close the upper opening and define a hollow interior,
wherein the hosel flange region is defined as an interface between the hosel and the rest of the body,
wherein the support ring is contained within the hollow interior and extends along the flange region from the heel side to the return portion,
wherein the support ring contacts an inner surface of the front wall,
wherein the support ring has a maximum length of approximately 0.125 inch and a maximum thickness of approximately 0.060 inch, and
wherein the golf club head has a volume of 50 to 250 cubic centimeters.
17. The fairway wood-type golf club head of claim 16 , wherein the crown is affixed to the bond flange with a permanent adhesive material.
