Abstract

A golf club including a shaft and a club head coupled to the shaft. The club head includes a strike face, a shell defining an interior volume and a skeletal structure. The skeletal structure advantageously comprises a plurality of elongate skeletal members and a weight substantially entirely supported by the skeletal structure, wherein the weight and the skeletal structure collectively comprise at least 30% of the entire weight of the club head.

Claims

1. A golf club, comprising:

a shaft;

a club head coupled to the shaft, the club head comprising a strike face, a sole plate, a shell defining an interior volume, and skeletal structure comprised of a plurality of elongated ribs secured to the sole plate; and

a weight substantially entirely supported by the ribs, wherein the weight and the skeletal structure are substantially entirely located within a lower half of the interior volume, the lower half of the interior volume being adjacent the sole plate, the weight and the skeletal structure collectively comprising at least 30% of the entire weight of the club head.

2. The golf club of claim 1, wherein the shell encloses the skeletal structure.

3. The golf club of claim 2, wherein the ribs are attached to the periphery of the strike face.

4. The golf club of claim 1, wherein the shell comprises a material that plastically deforms or breaks when subject to impact with a golf ball at a speed of 100 mph.

5. The golf club of claim 1, wherein the club head further comprises a strike plate that defines the strike face and wherein at least one of the ribs extends rearwardly from the strike face.

6. The golf club of claim 1, wherein the weight is suspended within the interior volume.

7. The golf club of claim 1, wherein each of the ribs is secured to the sole plate substantially entirely along the rib'"'"'s length.

8. The golf club of claim 1, wherein at least one of the ribs has a rearward end extending rearward of the sole plate, the weight being secured to the rearward end.

9. The golf club of claim 1, wherein at least one of the ribs has a rearward end projecting upward from the sole plate, the weight being secured to the rearward end.

10. A golf club, comprising:

a shaft; and

a club head coupled to the shaft, the club head comprising a strike plate defining a strike face, a shell defining an interior volume, a sole plate, and a skeletal structure reinforcing the sole plate, the skeletal structure being substantially entirely located within a lower half of the interior volume, the lower half being adjacent to the sole plate, wherein the strike plate and skeletal structure bear at least 50% of the load when a golf ball is struck by the strike face.

11. The golf club of claim 10, wherein the skeletal structure comprises a plurality of ribs secured to the sole plate.

12. A golf club, comprising:

a shaft;

a golf club head coupled to the shaft, the golf club head comprising a strike plate and a shell having an interior surface defining exactly one contiguous interior volume;

said strike plate and said shell defining a substantially closed exterior envelope; and

a weight, wherein the weight comprises at least 20% of the weight of the club head and the weight is spaced at least 5 mm from the envelope defined by the outer shell and the strike plate, the weight being completely inside of and not forming a portion of the exterior envelope.

13. A golf club, comprising:

a shaft;

a club head coupled to said shaft, said club head comprising a strike face, a shell defining an interior volume, and a compliant skeletal structure acting upon the strike face, the skeletal structure comprising a plurality of elongate skeletal members; and

a weight substantially entirely supported by said skeletal structure;

wherein the compliance of said skeletal structure is such that an impact of said strike face with a golf ball causes both said strike face and the ball to elastically deform and then return to undeformed shapes of said strike face and the ball, wherein said strike face and the ball return to said undeformed shapes at substantially the same moment after the impact.

14. The golf club of claim 13, said skeletal members being curved to provide compliance to said skeletal structure.

15. A golf club, comprising:

a shaft; and

a club head coupled to the shaft, the club head comprising a strike face, a sole plate, a skeletal structure comprised of a plurality of elongate skeletal members secured along portions of their lengths to the sole plate, and a weight plug supported by the skeletal structure, wherein at least one of the skeletal members has a rearward end extending rearward of the sole plate, the weight plug being secured toe,the rearward end, substantially all of said skeletal members originating from said strike face.

16. A golf club, comprising:

a shaft; and

a club head coupled to the shaft, the club head comprising a strike face, a sole plate, a skeletal structure comprised of a plurality of elongate skeletal members secured along portions of their lengths to the sole plate, and a weight plug supported by the skeletal structure, wherein at least one of the skeletal members has a rearward end projecting upward from the sole plate, the weight plug being secured to the rearward end substantially all of said skeletal members originated from said strike face.

17. A golf club, comprising:

a shaft;

a club head coupled to the shaft, the club head comprising a strike face, a sole plate, a shell having an interior surface defining an interior volume, and a skeletal structure comprised of a plurality of elongate skeletal members being secured along portions of their lengths to the sole plate, substantially all of the skeletal members originating from the strike face; and

a weight plug supported by the skeletal structure, wherein substantially all of the elongate members terminate at the weight plug substantially within a rear half of the interior volume, the rear half of the interior volume being located opposite a remaining front half of the interior volume adjacent to the strike face.

18. A golf club comprising:

a shaft;

a club head adjoining the shaft and defining an interior volume, the club head comprising a strike plate, a sole plate, and a plurality of elongated skeletal members located within the interior volume, a majority of the length of each of the skeletal members being secured to the sole plate; and

a weight substantially entirely located in a rear half of the interior volume;

wherein each of the skeletal members originates from the strike plate and terminates at the weight.

19. A golf club, comprising:

a shaft;

a club head coupled to the shaft, the club head comprising a strike face, a sole plate, a shell defining an interior volume, and a skeletal structure comprised of a plurality of elongated ribs secured to the sole plate, and

a weight substantially entirely supported by the ribs;

wherein the weight and the skeletal structure collectively comprise at least 30% of the entire weight of the club head, the weight being suspended within the interior volume.

20. A golf club, comprising:

a shaft;

a club head coupled to the shaft, the club head comprising a strike face, a sole plate, a shell defining an interior volume, and a skeletal structure comprised of a plurality of elongated ribs secured to the sole plate, and;

a weight substantially entirely supported by the ribs, wherein the weight and the skeletal structure collectively comprise at least 30% of the entire weight of the club head, at least one of the ribs having a rearward end extending rearward of the sole plate, the weight being secured to the rearward end.
