Abstract

Embodiments of golf clubs head sets with varying characteristics are disclosed herein. Other examples and related methods are also generally described herein.

Claims

1. A golf club head comprising:

a front face; and

a back portion comprising;

a heel region;

a toe region;

a center region between the heel and toe regions;

a back end extended between the heel and toe regions; and

a cavity comprising;

a cavity heel zone;

a cavity toe zone;

a cavity center zone between the cavity heel and toe zones;

a cavity inner section located towards the front face; and

a cavity outer section located towards the back end;

wherein the cavity is wider at the cavity center zone than at the cavity heel and toe zones.

2. The golf club head of claim 1, wherein:

a distance between the front face and an exposed surface of the cavity inner section is greater at the cavity heel and toe zones than at the cavity center zone.

3. The golf club head of claim 1, wherein:

a distance between the back end and an exposed surface of the cavity outer section is greater at the cavity heel and toe zones than at the cavity center zone.

4. The golf club head of claim 1, wherein:

a distribution of mass of the cavity inner section is shifted towards the heel and toe regions and away from the cavity center zone.

5. The golf club head of claim 1, wherein:

the back portion comprises a back face opposite the front face and extended between the heel and toe regions; and

the cavity is located between the back face and the back end.

6. The golf club head of claim 1, further comprising:

an insert comprising;

an insert heel zone;

an insert toe zone; and

an insert center zone;

the insert is configured to be at least partially housed in the cavity.

7. The golf club head of claim 6, wherein:

the insert center zone is thicker than the insert heel and toe zones.

8. The golf club head of claim 6, wherein:

a distribution of mass of the insert is concentrated at the insert center zone and diminishes towards the insert heel and toe zones.

9. The golf club head of claim 6, wherein:

a density of a body of the golf club head is greater than a density of the insert.

10. The golf club head of claim 6, wherein:

the cavity inner section extends from the cavity and towards the front face;

the golf club head comprises a moment of inertia about the center region;

the moment of inertia comprises;

a first portion of the moment of inertia contributed by the cavity inner section at the cavity heel and toe zones; and

a second portion of the moment of inertia contributed by the insert at the insert heel and toe zones; and

the first portion of the moment of inertia is greater than the second portion of the moment of inertia.

11. The golf club head of claim 6, wherein:

the insert heel and toe zones are obtusely angled relative to each other about the insert center zone.

12. The golf club head of claim 11, wherein:

the insert comprises an insert inner wall complementary to the cavity inner section;

the insert heel and toe zones are obtusely angled relative to each other along the insert inner wall; and

the cavity inner section is obtusely angled complementarily to the insert inner wall.

13. The golf club head of claim 6, wherein:

the insert is insertable into the cavity in a top-to-sole direction; and

the insert is interchangeable with a second insert.

14. The golf club head of claim 6, wherein:

the insert comprises a grip portion to aid during removal of the insert from the cavity; and

the grip portion is configured to remain external to the cavity when the insert is inserted into the cavity.

15. The golf club head of claim 6, wherein:

the insert comprises;

a specific gravity of at least approximately 1.2 g/cm³; and

a mass of approximately 10 grams;

and

the body comprises a specific gravity of at least approximately 5.0 g/cm³.

16. A method comprising:

providing an insert for a golf club head;

wherein providing the insert comprises;

providing insert heel and toe zones; and

providing an insert center zone between the insert heel and toe zones that is thicker than the insert heel and toe zones.

17. The method of claim 16, further comprising:

providing a body of the golf club head;

wherein;

providing the body comprises;

providing a back face and a back end at a back portion of the body; and

providing a cavity between the back face and the back end, the cavity comprising;

a cavity inner section adjacent to the back face;

a cavity outer section opposite the back end;

cavity heel and toe zones; and

a cavity center zone between the cavity heel and toe zones that is thicker than the cavity heel and toe zones;

and

providing the insert comprises;

providing the insert to be at least partially housed in the cavity.

18. The method of claim 17, wherein:

providing the insert comprises;

providing an insert front end configured to face the cavity inner section when the insert is inserted into the cavity;

providing an insert rear end configured to face the cavity outer section when the insert is inserted into the cavity; and

providing the insert center zone to be thicker, from the insert front end to the insert rear end, than the insert heel and toe zones.

and

providing the cavity comprises;

providing the cavity center zone to be thicker, from the cavity inner section to the cavity outer section, than the cavity heel and toe zones.

19. The method of claim 17, further comprising:

inserting the insert into the cavity of the body of the golf club head.

20. A golf club head comprising:

a back portion of a body of the club head, the back portion comprising;

a heel region;

a toe region;

a center region between the heel and toe regions;

a back surface opposite the front face and extended between the heel and toe regions;

a back wall extended between the heel and toe regions; and

a cavity located between the back surface and the back wall and comprising;

a cavity heel zone;

a cavity toe zone;

a cavity center zone between the cavity heel and toe zones;

a cavity inner wall comprising a portion of the back surface; and

a cavity outer wall located opposite the back wall;

an insert comprising;

an insert heel zone;

an insert toe zone;

an insert center zone between the insert heel and toe zones;

an insert inner wall complementary to the cavity inner wall; and

an insert outer wall complementary to the cavity outer wall;
