Abstract

A novel golf club includes an elongated metal shaft and a metal club head secured to a lower end portion thereof. The club head comprises an integrally molded body having a hollow interior with an opening outwardly onto a planar front face. A plurality of metal face plates, each having a planar back face with an outer periphery matching the periphery of the front face of the club head body are adapted to be mounted on the body closing off the hollow opening thereof and secured in place with fasteners. Each face plate includes a ball engaging outer face having a set of characteristics comprising a curved bulge from toe to heel, a curved roll from bottom to top and a degree of angular loft relative to a bottom edge, and at least one of the characteristics of a selected face plate is different from that of the other(s) to impart a different path to a ball when struck thereby. The top and bottom walls, and the toe and heel portions of the club head taper from a minimum thickness rearwardly of the front face to a maximum thickness at the front face around the hollow opening.

Claims

1. A wood type golf club comprising:

an elongated shaft; and

a metal club head secured to a lower end portion of said shaft,

said club head comprising an integrally molded body having a hollow interior with an opening outwardly onto a substantially planar front face;

a plurality of interchangeable, ball engaging, metal face plates, each of said plates including a substantially planar back face having a surface and a peripheral edge matching the surface and the peripheral edge around said planar front face of said body; and

a plurality of fasteners for securing a selected one of said face plates with its back face held tightly against said front face of said body to close said hollow opening of said club head in readiness for use,

each of said face plates having a ball engaging, outer face spaced apart from and opposite said back face, said outer face formed with a set of characteristics including a curved bulge from toe to heel, a curved roll from bottom to top and a degree of angular loft relative to a bottom edge, and at least one of said characteristics of one face plate being different than that of another face plate to impart a different path to a ball when struck thereby,

said club head body having spaced apart top and bottom walls extending rearwardly of said front face and a curved back wall spaced rearwardly of said front face integrally joining rearward portions of said top and bottom walls, said body further including spaced apart toe and heel portions extending rearwardly of said front face and integrally joining opposite edge portions of said top and bottom wall and having rearward portions integrally joining upstanding opposite edge portions of said rear wall,

said top and bottom walls having a minimum wall thickness adjacent said rearward portion gradually tapering toward a maximum wall thickness at said front face above and below said hollow opening, said toe and heel portions increasing substantially in thickness from said rearward portions joining said rear wall to a maximum wall thickness at said front face which is substantially thicker than said maximum wall thickness of said top and bottom wall measured at a level on said toe and heel portions that is intermediate said top and bottom walls joined therewith.

2. The golf club of claim 1 wherein said toe portion has an outer surface convexly curved between the top and botton and between said front face and said rear wall, said heel portion having an outer surface convexly curved between the top and bottom and between said front face and said rear wall, and wherein said back wall has an outer surface convexly curved between the top and bottom and between said upstanding opposite edge portions joining said heel and toe portions.

3. The golf club of claim 2 wherein said top wall has an outer surface convexly curved between said toe and heel portions and between said front face and said back wall.

4. The golf club of claim 3 wherein said toe and heel portions have inner surfaces curved inwardly toward one another and spaced apart a minimum distance at said front face and a maximum distance where joined with said back wall.

5. The golf club of claim 4 wherein said plurality of fasteners comprises a pair of threaded fasteners extending between said face plate on the one hand and forward portions of said toe and heel portions on the other hand, each having said maximum wall thickness and spaced on opposite sides of said opening on said front face of said club head.

6. The golf club of claim 1 wherein said opening on said front face is oblong in shpe with rounded corners and is surrounded by said maximum wall thickness portion of said top and bottom walls and said toe and heel portions.
