Abstract

Embodiments of golf club heads with hosel inserts are presented herein. Other embodiments can be described and claimed.

First claim

What is claimed is:

1. A golf club comprising:
a golf club head comprising:
a hollow body comprising a first material having a first density and further comprising:
a strike face;
a crown coupled to the strike face comprising a crown hole opening into an interior of the hollow body;
a sole coupled to the strike face;
an interior surface forming an outer boundary of the interior of the hollow body; and
a support structure coupled to the interior surface and aligned with the crown hole;

a hosel insert comprising a first hosel portion configured to house a shaft tip and a second hosel portion adjacent to the first hosel portion; and
a shaft comprising the shaft tip, the shaft tip located within the first hosel portion of the hosel insert;
wherein:
the hosel insert is located within the crown hole and comprises a second material having a second density;
the second material is different than the first material;
the second density is less than the first density;
the first hosel portion engages the crown hole;
the second hosel portion engages the support structure; the strike face has an exterior strike face surface configured to strike a golf ball, and an interior strike face surface opposite the exterior strike face surface and forming a portion of the outer boundary of the interior of the hollow body; the support structure is a support structure boss coupled with the interior strike face surface and spaced between the sole and the crown hole; and the support structure comprises a second hole extending entirely through the support structure, the second hosel portion extends through the second hole, and the support structure supports the second hosel portion.

2. The golf club of claim 1 , wherein:
the first density is approximately 4.5 g/cm 3 ; and
the second density is approximately 1.7 g/cm 3 .

3. The golf club of claim 1 , wherein:
the crown hole comprises a crown hole cross section;
the hosel insert comprises at least one hosel insert exterior cross section; and
the crown hole cross section and the at least one hosel insert exterior cross section are substantially the same shape.

4. The golf club of claim 1 , wherein:
the crown hole comprises a first part of a two part mechanical fastener;
the hosel insert comprises a second part of the two part mechanical fastener; and
the first part is complementary to the second part.

5. The golf club of claim 1 , wherein:
the hosel insert comprises a hosel tip located proximate to the crown hole; and
the hosel tip is configured to engage a tool to secure the hosel tip to the crown hole.

6. The golf club of claim 1 , wherein:
the crown hole comprises a crown hole diameter between approximately 0.75 inches and approximately 0.25 inches; and
the hosel insert comprises at least a first hosel outside diameter between approximately 0.75 inches and approximately 0.25 inches.

7. The golf club of claim 1 , wherein:
the hosel insert comprises a length between approximately 0.25 inches and approximately 3.0 inches.

8. The golf club of claim 1 , wherein:
the hosel insert comprises at least one opening at a non-end portion of a sidewall of the hosel insert.

9. The golf club of claim 1 , wherein:
the first density is between approximately 2.6 g/cm 3 and approximately 7.8 g/cm 3 ; and
the second density is between approximately 1.0 g/cm 3 and approximately 2.8 g/cm 3 .

10. The golf club of claim 1 , wherein:
the strike face comprises titanium; and
the hosel insert comprises magnesium.

11. The golf club of claim 1 , wherein:
the first material has a first dampening capacity;
the second material has a second dampening capacity; and
the first dampening capacity is less than the second dampening capacity.

12. A golf club head comprising:
a hollow body comprising a first material and further comprising:
a strike face;
a crown coupled to the strike face and comprising a crown hole opening into an interior of the hollow body;
a sole coupled to the strike face;
an interior surface forming an outer boundary of the interior of the hollow body; and
a support structure coupled to the interior surface and aligned with the crown hole; and

a hosel insert comprising a first hosel portion configured to house a shaft tip and a second hosel portion adjacent to the first hosel portion;
wherein:
the first hosel portion engages the crown hole;
the second hosel portion engages the support structure;
the hosel insert comprises a second material different from the first material;
the strike face has an exterior strike face surface configured to strike a golf ball, and an interior strike face surface opposite the exterior strike face surface and forming a portion of the outer boundary of the interior of the hollow body;
the support structure is a support structure boss coupled with the interior strike face surface and spaced between the sole and the crown hole; and
the support structure comprises a second hole extending entirely through the support structure, the second hosel portion extends through the second hole, and the support structure supports the second hosel portion.

13. The golf club head of claim 12 wherein:
the second material comprises a lower density than the first material.

14. The golf club head of claim 12 , wherein:
the second hosel portion comprises a substantially circular cross section; and
the support structure comprises a complementary circular shape.

15. The golf club head of claim 12 , wherein:
the first hosel portion comprises a first part of a two part mechanical fastener;
the crown hole comprises a second part of the two part mechanical fastener; and
the second part is complementary to the first part.

16. The golf club head of claim 12 , wherein:
the first hosel portion further comprises a hosel end configured to engage a tool for securing the first hosel portion to the crown hole.

17. The golf club head of claim 12 , wherein:
at least one of a braze, a weld, or an adhesive fixes the first hosel portion to the crown hole.

18. The golf club head of claim 12 , wherein:
a non-end portion of a sidewall of the first hosel portion of the hosel insert comprises at least one opening to reduce a mass of the hosel insert.

19. The golf club head of claim 12 , wherein:
the first hosel portion has an exterior first hosel portion adjacent to the outer boundary of the interior of the hollow body; and
the exterior first hosel portion comprises a flange, the flange engaging the crown hole.

20. The golf club head of claim 12 , wherein:
the hosel comprises a hollow tubular body, a first hosel end proximate the first hosel portion, and a second hosel end proximate the second hosel portion; and
a barrier within the hollow tubular body between the first hosel end and the second hosel end.

21. The golf club head of claim 12 , wherein:
the second hosel portion is received by the support structure approximately 0.75 inches above the sole.

22. A method for providing a golf club, the method comprising:
providing a golf club head comprising:
a hollow body comprising a first material having a first density and further comprising:
a strike face;
