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 club head body comprising a first metallic material having a first density and further comprising:
a hollow interior;
a strike face;
a crown portion comprising a crown hole opening into the hollow interior;
a sole portion; and
a support structure located between the crown portion and the sole portion, the support structure comprising a structure hole aligned with the crown hole, and the structure hole having a first aperture opening into the hollow interior toward the crown hole and a second aperture opposite the first aperture and opening into the hollow interior away from the crown hole;
a shaft comprising a shaft tip; and
a hosel insert comprising a second metallic material having a second density;
a hollow tubular body;
a first hosel portion configured to receive the shaft tip; and
a second hosel portion adjacent to the first hosel portion; and
a barrier;
wherein the barrier separates and isolates the first hosel portion from the second hosel portion;
such that the shaft tip abuts the barrier when the shaft is inserted into the hosel insert;
wherein:
the second density is less than the first density;
the crown hole is configured to receive the first hosel portion; and
the structure hole is configured to receive the second hosel portion;
wherein the hosel insert has a first end proximate the crown hole and a second end proximate the support structure and a sidewall located between the first end and the second end;
wherein the hosel insert comprises a plurality of voids in non-end portions of the sidewall of a hosel insert surface;
wherein the hosel insert is fixedly attached to the club head body.

2. The golf club of claim 1 , wherein:
the second material is different than the first material.

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

4. The golf club of claim 1 , wherein at least one of:
the first density is approximately 4.5 g/cm 3 ; or
the second density is approximately 1.7 g/cm 3 .

5. The golf club of claim 1 , wherein:
the second hosel portion is configured to be fixed to the support structure.

6. The golf club of claim 1 , wherein:
the second hosel portion is configured to be fixed to the support structure; and
the first hosel portion is configured to be fixed to the crown hole.

7. The golf club of claim 1 , wherein:
the structure 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.

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

9. The golf club of claim 1 , wherein:
the structure hole comprises a structure hole diameter between approximately 0.25 inches and approximately 0.75 inches; and
the second hosel portion comprises at least one hosel insert outside diameter between approximately 0.25 inches and approximately 0.75 inches.

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

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

12. 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.

13. The golf club of claim 1 , wherein:
the structure hole is located between approximately 0.25 inches to approximately 1.5 inches away from the sole portion.

14. The golf club of claim 1 , wherein:
the second hosel portion comprises a hosel flange;
the structure hole comprises a structure hole diameter; and
the hosel flange comprises a hosel flange diameter greater than the structure hole diameter.

15. A method comprising:
providing a golf club head, the providing the golf club head comprising:
forming a club head body comprising a first metallic material having a first density and further comprising:
a hollow interior;
a strike face;
a crown portion comprising a crown hole opening into the hollow interior;
a sole portion; and
a support structure located between the crown portion and the sole portion, the support structure comprising a structure hole aligned with the crown hole, and the structure hole having a first aperture opening into the hollow interior toward the crown hole and a second aperture opposite the first aperture and opening into the hollow interior away from the crown hole;
wherein:
the crown hole is configured to receive a first hosel portion of a hosel insert;
the structure hole is configured to receive a second hosel portion of the hosel insert;
the hosel insert comprises the first hosel portion, the second hosel portion, a barrier, and a second metallic material having a second density;
the first hosel portion is configured to receive a shaft tip of a shaft;
the second hosel portion is adjacent to the first hosel portion; and
the second density is less than the first density;
wherein the barrier separates and isolates the first hosel portion from the second hosel portion;
such that the shaft tip abuts the barrier when the shaft is inserted into the hosel insert;
wherein the hosel insert has a first end proximate the crown hole and a second end proximate the structure hole, and a sidewall located between the first end and the second end;
wherein the hosel insert comprises a plurality of voids in non-end portions of the sidewall of a hosel insert surface;
wherein the hosel insert is fixedly attached to the club head body.

16. The method of claim 15 , wherein:
the second material is different than the first material;
the first density is between approximately 2.6 g/cm 3 and approximately 7.8 g/cm 3 ;
