Abstract

A golf club head, and a process of manufacturing a golf club head, in which the golf club head includes a body having an interior space, a cover plate for attachment to the body, the cover plate having a surface forming a golf ball striking surface, and a quantity of material within at least a portion of the interior space, for assisting in securing the cover plate to the body. The quantity of material can be a filler material which is injected or poured, prior to installing the shaft on the club head, through sleeve which communicates with the interior space of the body of the head. Further, the golf club head may also include an internal transverse surface which can be defined, for example, by a separate partition which divides the interior space of the hollow body, so as to reduce the quantity of the filler material, and a member to hold the cover plate in place prior to the introduction of the filler material into the hollow body, for example, a member which is compressed between the internal transverse surface and the cover plate.

Claims

1. A golf club head comprising:

(a) a body having an interior space;

(b) a cover plate for attachment to said body, said cover plate being a separate member from said body and having a surface forming a golf ball striking surface; and

(c) means for securing said cover plate to said body, comprising a quantity of filler material within at least a portion of said interior space for pressing said cover plate against said body.

2. The golf club head of claim 1, wherein said quantity of material is a unitary mass of material.

3. The golf club head of claim 1, wherein said body comprises an opening communicating with said interior space and defined by a periphery and means on said periphery for positioning said cover plate relative to said body.

4. The golf club head of claim 3, further comprising means for holding said cover plate in a predetermined position prior to introducing said quantity of material within said interior space.

5. The golf club head of claim 4, wherein said means for holding said cover plate comprises an elastic means for pressing said cover plate against said periphery of said body.

6. The golf club head of claim 3, further comprising means for centering said cover plate relative to said periphery of said body.

7. The golf club head of claim 1, wherein said means for positioning said cover plate comprises a continuous peripheral shoulder.

8. The golf club head of claim 1, wherein said means for positioning said cover plate comprises a plurality of peripheral flanges.

9. The golf club head of claim 1, further comprising means for holding said cover plate in a predetermined position prior to introducing said quantity of material within said interior space.

10. The golf club head of claim 1, further comprising means extending from said cover plate for anchoring said cover plate to said quantity of material.

11. The golf club head of claim 1, further comprising a hollow sleeve affixed to said body and communicating with said interior space receiving said quantity of material and for receiving a shaft for a golf club comprised of said golf club head and said shaft.

12. The golf club head of claim 1, wherein said quantity of material is selected from the group consisting of polyamides, polyesters, polyethylenes and composites of any of the foregoing.

13. The golf club head of claim 1, wherein said quantity of material is at least partially formed of an elastomer.

14. The golf club head of claim 1, wherein said body is comprised of a material different from a material of which said cover plate is comprised.

15. The golf club comprising, in combination, the golf club head of claim 1, and a shaft attached to said body of said golf club head.

16. A golf club head comprising:

(a) a body having an interior space;

(b) a cover plate for attachment to said body, said cover plate having a surface forming a golf ball striking surface;

(c) means for securing said cover plate to said body, comprising a quantity of material within at least a portion of said interior space; and

(d) an interior surface positioned within said interior space, spaced from said cover plate, wherein said quantity of material is positioned between said interior surface and said cover plate.

17. The golf club head of claim 16, wherein said interior surface is defined by a partition positioned within said interior space.

18. The golf club head of claim 17, wherein said body comprises a first section and a second section, and wherein said first section and said second section are positioned on opposite sides of said partition.

19. The golf club head of claim 16, wherein said quantity of material includes a first quantity of material occupying a portion of said interior space, and wherein said interior surface comprises an exposed area of said first quantity of material within said portion of said interior space.

20. The golf club head of claim 16, further comprising means for holding said cover plate in a predetermined position prior to introducing said quantity of material within said interior space.

21. The golf club head of claim 20, wherein said means for holding said cover plate comprises an elastic means positioned between said interior surface and an interior surface of said cover plate for pressing said cover plate against said periphery of said body.

22. The golf club head of claim 16, wherein said interior surface is generally parallel to said surface of said cover plate.

23. A golf club head comprising:

(a) a body having an interior space, said body comprising an opening communicating with said interior space and defined by a periphery and means on said periphery for positioning said cover plate relative to said body;

(b) a cover plate for attachment to said body, said cover plate having a surface forming a golf ball striking surface;

(c) means for securing said cover plate to said body, comprising a quantity of material within at least a portion of said interior space; and

(d) an interior surface positioned within said interior space, spaced from said cover plate, wherein said quantity of material is positioned between said interior surface and said cover plate.

24. The golf club head of claim 23, wherein said interior surface is generally parallel to said surface of said cover plate.

25. A golf club head comprising:

(a) a body having an interior space;

(b) a cover plate for attachment to said body, said cover plate being a separate member from said body and having a surface forming a golf ball striking surface; and

(c) means for securing said cover plate to said body, comprising a quantity of filler material within at least a portion of said interior space for pressing said cover plate against said body;

wherein said body comprises an opening defined by a first periphery, said first periphery comprising a first tapered surface facing said interior space,

wherein said cover plate comprises a second periphery, said second periphery comprising a second tapered surface which mates with said first tapered surface when said cover plate is secured to said body, and

wherein said quantity of filler material further comprises means for pressing said second tapered surface of said cover plate against said first tapered surface of said body.
