Abstract

A golf club head for use in a golf club. The club head has a moulded main body with weighted inserts to improve striking characteristics. The club head includes a shaft anchoring element to attach the club head to a golf club shaft. In one embodiment the club head includes a hardened insert to form a striking face on the golf club. In a further embodiment, the golf club head is formed during a two-step process, first the moulding of a main body, then, the moulding of a insert to form a front face.

Claims

1. A golf club head comprising:

a main body moulded from a mouldable material having a first lower density;

an insert moulded into a face of main body to form a striking surface;

means for weighting said main body, said weighting means having a second higher density and being positioned within said main body to enhance the striking characteristics of the main body;

a shaft receiving bore formed in the main body; and

a shaft anchoring element proximate to said shaft receiving bore, said shaft anchoring element being moulded into said main body and being sized and shaped to receive a golf club shaft therein to securely attach a golf club shaft to said main body.

2. A golf club head as claimed in claim 1 wherein said mouldable main body is made from urethane.

3. A golf club head as claimed in claim 1 wherein said weighting means is made from metal.

4. A golf club head as claimed in claim 1 wherein said weighting means is made from metal and comprises a pair of opposed weights located generally symmetrically about a central axis of said main body, toward lateral side edges of said main body.

5. A golf club head as claimed in claim 4 wherein each weight includes a forward portion and a tapered rearward portion.

6. A golf club head as claimed in claim 5 wherein said weights include means for bonding to said moulded main body.

7. A golf club head as claimed in claim 6 wherein said bonding means comprises knurling on at least a portion of an outside of the weight.

8. A golf club head as claimed in claim 1 wherein said shaft anchoring element is metal and is moulded into said main body.

9. A golf club head as claimed in claim 8 wherein said shaft anchoring element includes a shaft receiving section for closely receiving a shaft therein to permit the formation of a bond between the shaft anchoring element and the shaft wherein said shaft is secured within said club head.

10. A golf club head as claimed in claim 9 wherein said shaft anchoring element includes a roughened surface to facilitate the bonding of said shaft anchoring element into said main body.

11. A golf club head as claimed in claim 10 wherein said shaft anchoring element includes an aperture for a set screw.

12. A golf club head as claimed in claim 10 wherein said shaft anchoring element is a tube of aluminium, and has an outer surface and an inner surface, wherein said outer surface is knurled to promote adhesion to said moulded main body and said inner surface is smooth to promote adhesion to said shaft.

13. A golf club head as claimed in claim 1 wherein said insert is moulded and is comprised of a material having a different hardness than said main body.

14. A golf club head as claimed in claim 13 wherein said insert has a higher hardness than said main body.

15. A golf club head as claimed in claim 14 wherein said insert is formed from moulded urethane and is tapered outwardly from front to back to retain said insert in place.

16. A golf club head as claimed in claim 15 wherein said weights are positioned in said moulded main body to extend rearwardly from an interface between said insert and said main body.

17. A golf club head as claimed in claim 1 wherein said moulded main body is formed with a front insert receiving pocket.

18. A golf club head as claimed in claim 1 further including aerodynamic ridges which extend from the front of the club head to the rear of the club head.

19. A golf club as claimed in claim 18 wherein said main body includes a rearwardly extending dimple on a top surface thereof.

20. A golf club head as claimed in claim 1 wherein said moulded main body includes at least one ridge extending parallel to the axis of movement of the club in use extending from a lower surface thereof.

21. A golf club head as claimed in claim 20 wherein said moulded main body includes two of said ridges.

22. A golf club comprising a golf head having a main body moulded from a mouldable material having a first lower density;

an insert moulded into a face of main body to form a striking surface;

means for weighting said main body, said weighting means having a second higher density and being positioned within said main body to enhance the striking characteristics of the main body;

a shaft receiving bore formed in the main body; and

a shaft anchoring element proximate to said shaft receiving bore, said shaft anchoring element being moulded into said main body and being sized and shaped to receive a golf club shaft therein to securely attach a golf club shaft to said main body a golf club shaft secured to said golf club head

and a grip secured to said golf club shaft.

23. A golf club head comprising:

a main body moulded from a mouldable material having a first lower density and a first hardness;

means for weighting said main body, said weighting means having a second higher density and being positioned laterally within said main body to enhance the striking characteristics of the main body when used as a club head;

a shaft receiving bore formed in the main body; and

a moulded face insert on said main body having a second hardness which is greater than said first hardness and which forms a striking surface on said golf club head.

24. A golf club head as claimed in claim 23 wherein said means for weighing said main body extends rearwardly in said main body from an interface between the main body and the moulded insert.

25. A golf club head as claimed in claim 23 wherein said first hardness is in the range of 60 to 75 on the Durometer D scale and said second hardness is in the range of 80 to 90 on the Durometer D scale.
