Abstract

An iron-type golf club head includes a body having a front face arranged for impact with a golf ball, a heel end, a toe end and a beveled sole. The beveled sole has leading and trailing edges with a ridge located between them. The beveled sole includes a primary surface and a secondary surface, both of which vary in width from the heel end to the toe end. The primary surface is located between the leading edge and the ridge, and the secondary surface is located between the trailing edge and the ridge. The primary surface has a first width dimension adjacent the heel end, a second width dimension measured along a center line located substantially between the heel and toe ends, and a third width dimension adjacent the toe end. The first and third width dimensions of the primary surface are less than the second width dimension of the primary surface. The secondary surface has a first width dimension adjacent the heel end, a second width dimension measured along the center line, and a third width dimension adjacent the toe end. The first and third width dimensions of the secondary surface are greater than the second width dimension of the secondary surface.

Claims

1. A golf club head of an iron-type comprising:

a body having a front face arranged for impact with a golf ball, a heel end, a toe end and a beveled sole;

said beveled sole having a leading edge disposed along a bottom portion of said front face, a trailing edge disposed rearwardly of said leading edge, and a ridge located between said leading and trailing edges;

said beveled sole having a primary surface located between said leading edge and said ridge, said primary surface varying in width from said heel end to said toe end, said primary surface having a first width dimension adjacent said heel end and a second width dimension measured along a center line located substantially midway between said heel and toe ends, said first width dimension of said primary surface being less than said second width dimension of said primary surface; and

said beveled sole also having a secondary surface located between said trailing edge and said ridge, said secondary surface meeting said primary surface along said ridge and being disposed at an obtuse angle to said primary surface, said secondary surface also varying in width from said heel end to said toe end, said secondary surface having a first width dimension adjacent said heel end and a second width dimension measured along said center line, said first width dimension of said secondary surface being greater than said second width dimension of said secondary surface.

2. The golf club head of claim 1, wherein said front face has a loft angle at least 48 degrees.

3. The golf club head of claim 1, further comprising:

a hosel connected to said heel end of said body and adapted for receiving a shaft, said hosel having a longitudinal axis; and

said primary surface of said beveled sole has a heel extension that is intersected by the longitudinal axis of said hosel.

4. The golf club head of claim 1, further comprising:

said body including a back face opposite said front face;

said back face having an elongated cavity formed therein; and

a weight member disposed in said cavity.

5. The golf club head of claim 4, wherein said cavity extends into a lower thickened section of said body.

6. The golf club head of claim 1, wherein said primary surface of said beveled sole has a third width dimension adjacent said toe end, and wherein said third width dimension of said primary surface is less than said second width dimension of said primary surface.

7. The golf club head of claim 1, wherein said secondary surface of said beveled sole has a third width dimension adjacent said toe end, and wherein said third width dimension of said secondary surface is greater than said second width dimension of said secondary surface.

8. A golf club head of an iron-type comprising:

a body having a front face arranged for impact with a golf ball, a heel end, a toe end and a beveled sole;

said beveled sole having a leading edge disposed along a bottom portion of said front face, a trailing edge disposed rearwardly of said leading edge, and a ridge located between said leading and trailing edges;

said beveled sole having a primary surface located between said leading edge and said ridge, said primary surface varying in width from said heel end to said toe end, said primary surface having a first width dimension adjacent said heel end, a second width dimension measured along a center line located substantially midway between said heel and toe ends and a third width dimension adjacent said toe end, said first and third width dimensions of said primary surface being less than said second width dimension of said primary surface; and

said beveled sole also having a secondary surface located between said trailing edge and said ridge, said secondary surface meeting said primary surface along said ridge and being disposed at an obtuse angle to said primary surface, said secondary surface also varying in width from said heel end to said toe end, said secondary surface having a first width dimension adjacent said heel end, a second width dimension measured along said center line and a third width dimension adjacent said toe end, said first and third width dimensions of said secondary surface being greater than said second width dimension of said secondary surface.

9. The golf club head of claim 8, further comprising:

a hosel connected to said body and adapted for receiving a shaft, said hosel having a longitudinal axis; and

said primary surface of said beveled sole having a heel extension intersected by the longitudinal axis of said hosel.

10. A golf club head of an iron-type comprising:

a body having a front face arranged for impact with a golf ball, a back face opposite said front face, a heel end, a toe end and a beveled sole, said front face having a loft angle of at least 48 degrees, said back face having an elongated cavity extending into a thickened section of said body;

a weight member disposed in said cavity;

a hosel connected to said heel end of said body and adapted for receiving a shaft, said hosel having a longitudinal axis;

said beveled sole having a leading edge disposed along a bottom portion of said front face, a trailing edge disposed rearwardly of said leading edge, and a ridge located between said leading and trailing edges;

said beveled sole having a primary surface located between said leading edge and said ridge, said primary surface varying in width from said heel end to said toe end, said primary surface having a first width dimension adjacent said heel end, a second width dimension measured along a center line located substantially midway between said heel and toe ends and a third width dimension adjacent said toe end, said first and third width dimensions of said primary surface being less than said second width dimension of said primary surface;

said primary surface of said beveled sole having a heel extension intersected by the longitudinal axis of said hosel; and

said beveled sole also having a secondary surface located between said trailing edge and said ridge, said secondary surface meeting said primary surface along said ridge and being disposed at an obtuse angle to said primary surface, said secondary surface also varying in width from said heel end to said toe end, said secondary surface having a first width dimension adjacent said heel end, a second width dimension measured along said center line and a third width dimension adjacent said toe end, said first and third width dimensions of said secondary surface being greater than said second width dimension of said secondary surface.
