Abstract

A golf club head (such as a putter head), has a face that includes a ball-contacting region. The ball-contacting region has an inset containing an elastically deformable material and at least one rigid element disposed within the elastically deformable material. When a golf ball is struck, the elastically deformable material compresses and the rigid element imparts overspin to the ball that causes it to roll more accurately.

Claims

1. A golf club head comprising a face having a ball-contacting region, wherein the ball-contacting region comprises an inset containing an elastically deformable material having a surface, and at least one rigid element disposed within the elastically deformable material, wherein the at least one rigid element is shaped as an elongated polygon having a longitudinal axis generally perpendicular to the face, such that an edge portion of the at least one rigid element is proximate and angled with respect to the surface of the elastically deformable material.

2. The golf club head of claim 1 wherein the elastically deformable material comprises a polymeric material.

3. The golf club head of claim 2 wherein the polymeric material is selected from the group consisting of thermoplastic elastomers, thermoplastic olefins, soft thermoplastic polyolefin, ethylene-vinylacetate copolymer, ethylene propylene rubber, and combinations thereof.

4. The golf club head of claim 1 wherein the at least one rigid element comprises at least one blade.

5. The golf club head of claim 4 wherein the at least one blade is shaped as a trapezoid.

6. The golf club head of claim 1 wherein the at least one rigid element is angled at an angle of from about 30 to about 60 degrees with respect to the face.

7. The golf club head of claim 1 wherein the inset containing the elastically deformable material has an upper portion and a lower portion, wherein the at least one rigid element is disposed only in the upper portion of the inset.

8. A golf club having an elongate shaft and a head positioned on an end of the shaft, the head comprising:

a face having a ball-contacting region, wherein the ball-contacting region comprises an inset containing an elastically deformable material having a surface, and at least one rigid element disposed within the elastically deformable material, wherein the at least one rigid element is shaped as an elongated polygon having a longitudinal axis generally perpendicular to the face, such that an edge portion of the at least one rigid element is proximate and angled with respect to the surface of the elastically deformable material.

9. The golf club of claim 8 wherein the elastically deformable material comprises a polymeric material.

10. The golf club of claim 8 wherein the polymeric material is selected from the group consisting of thermoplastic elastomers, thermoplastic olefins, soft thermoplastic polyolefin, ethylene-vinylacetate copolymer, ethylene propylene rubber, and combinations thereof.

11. The golf club of claim 8 wherein the at least one rigid element comprises at least one blade.

12. The golf club of claim 11 wherein the at least one blade is shaped as a trapezoid.

13. The golf club of claim 8 wherein the at least one rigid element is angled at an angle of from about 30 to about 60 degrees with respect to the face.

14. The golf club of claim 8 wherein the inset containing the elastically deformable material has an upper portion and a lower portion, wherein the at least one rigid element is disposed only in the upper portion of the inset.
