Abstract

A golf club head having a body defining a heel, toe, top wall, sole, and a front wall defining an upwardly and rearwardly inclined front face in ball-addressing position of the head, and comprising

a) said body defining a forwardly extending main recess located rearwardly of said front wall,

b) and said body having upper and lower projections extending rearwardly from said front wall above and below said main recess, said projections being rearwardly elongated and said recess being horizontally elongated in said ball-addressing position of the head.

Claims

1. A golf club head having a body defining a heel, toe, top wall, sole, and a front wall defining an upwardly and rearwardly inclined front face in ball-addressing position of the head, and comprising

a) said body defining a forwardly extending main recess located rearwardly of said front wall,

b) and said body having upper and lower projections extending rearwardly from said front wall respectively above and below said main recess, said projections being rearwardly elongated and said recess being rearwardly elongated in said ball-addressing position of the head,

c) said projections tapering rearwardly,

d) said upper projection having a lower surface and said lower projection having an upper surface, a vertical plane normal to said front face intersecting said surfaces to define lines that extend substantially horizontally rearwardly in substantially parallel relation in said ball-addressing position.

2. The club head of claim 1 wherein said lower surface is upwardly concave along its length in a direction between the heel and toe.

3. The golf club head of claim 1 wherein said body has a third rearward projection at said toe and which is rearwardly elongated adjacent said rearwardly elongated recess.

4. The golf club head of claim 3 wherein said third projection has an inner surface characterized in that horizontal planes intersect said inner surface to define lines that extend horizontally rearwardly in said ball-addressing position.

5. The golf club head of claim 1 wherein at least one of said upper and lower projections has an inner surface adjacent said recess, and an outer surface, one of said inner and outer surfaces tapering relatively toward the other of said inner and outer surfaces.

6. The golf club head of claim 4 wherein said third projection tapers rearwardly.

7. The golf club head of claim 1 wherein said body is metallic.

8. The golf club of claim 1 wherein said body consists of a metallic casting.

9. The golf club head of claim 7 wherein said body is a one-piece casting, and defines an iron golf club head.

10. The golf club head of claim 3 wherein said third projection has an inner surface facing said recess characterized in that forwardly extending planes intersecting said third projection inner surface defines lines that project horizontally rearwardly in said ball-addressing position.

11. The golf club head of claim 1 wherein each of said rearward projections has an overall rearward length dimension and a thickness dimension outwardly from said recess, said length dimension substantially exceeding said thickness dimension.

12. The golf club head of claim 3 wherein said third projection arcuately merges with each of said upper and lower projections to define two arcuate and rearwardly extending corner projections, each of which has an inner corner surface facing said recess, forwardly extending planes intersecting said corner surfaces to define lines projecting substantially horizontally rearwardly in said ball-addressing position.

13. The golf club head of claim 12 wherein said body has at least one slit extending rearwardly in at least one of said projections and outwardly from said main recess.

14. The golf club head of claim 13 wherein there are multiple of said slits in multiple of said rearward projections.

15. The golf club head of claim 3 wherein said body has four of said slits located outwardly from said main recess as follows:

proximate the junction of the heel and top wall

proximate the junction of the heel and bottom wall

proximate the junction of the toe and top wall

proximate the junction of the toe and

bottom wall.

16. The golf club head of claim 4 wherein said body has a fourth rearwardly projecting surface adjacent said recess and being closer to the heel than said upper, lower and third surfaces, horizontal planes intersecting said fourth surface defining lines that extend substantially horizontally rearwardly in said ball-addressing position.

17. Multiple golf clubs in a set, each club having a head, each head having a configuration as defined in claim 1, the inclined front faces of the heads in the set having increasing rearward angularity.

18. Multiple golf clubs in a set, each club having a head, each head having a configuration as defined in claim 10, the inclined front faces of the heads in the set having increasing rearward angularity.

19. Multiple golf club heads in a set, each head having a body defining a heel, toe, top wall, bottom wall, and a front wall defining an upwardly and rearwardly inclined front face, and comprising

a) said body defining a forwardly extending main recess located rearwardly of said front wall, each said recess and the boundaries thereof, extending horizontally rearwardly in ball address position,

b) said body having rearwardly elongated projections at the top wall, bottom wall and toe,

c) said projections tapering rearwardly,

d) at least two of said projections having corner surfaces facing said recess, forwardly extending planes intersecting said surfaces to define horizontally rearwardly extending lines, in ball-addressing position of the head.
