Abstract

An iron type golf club head includes a body having a front face arranged for impact with a golf ball, a back face, a heel portion and toe portion. A perimeter weighting element protrudes rearwardly from the front face and defines a primary cavity in the back face of the body. The perimeter weighting element includes a top rail and a sole which extend between the body heel and toe portions along an upper portion and a lower portion, respectively, of the body. An interior wall extends from a first end located adjacent the body heel portion through the primary cavity between the top rail and the sole to a second end located adjacent the body toe portion. The interior wall defines a secondary cavity within the primary cavity, and a weight adjustment member is disposed in the secondary cavity. The weight adjustment member is selected from a plurality of weight adjustment members and is used to overcome manufacturing tolerances and to adjust golf club swingweights.

Claims

1. An iron type golf club head comprising:

a body having a front face arranged for impact with a golf ball, a back face, a heel portion and a toe portion;

a perimeter weighting element protruding rearwardly from said front face defining a primary cavity in said back face, said perimeter weighting element including a top rail extending between said heel and toe portions along an upper portion of said body, said perimeter weighting element also including a sole extending between said heel and toe portions along a lower portion of said body,

an interior wall extending from a first end connected to said perimeter weighting element adjacent said body heel portion through said primary cavity between said top rail and said sole to a second end connected to said perimeter weighting element adjacent the body toe portion defining a secondary cavity within said primary cavity, said interior wall having a height dimension that varies between said first and second ends thereof with said height dimension being greater at said second end than at said first end; and

a weight adjustment member disposed in said secondary cavity.

2. The iron type golf club head of claim 1, wherein said primary cavity has a bottom surface, and wherein said interior wall is integrally formed on said bottom surface of said primary cavity.

3. The iron type golf club head of claim 1, wherein said weight adjustment member is selected from a plurality of weight adjustment members of different weights.

4. In an iron type golf club head including a body having a front face arranged for impact with a golf ball, a back face, a heel portion, a toe portion, a perimeter weighting element protruding rearwardly from said front face defining a primary cavity in said back face, said perimeter weighting element including a top rail extending between said heel and toe portions along an upper portion of said body, said perimeter weighting element also including a sole extending between said heel and toe portions along a lower portion of said body, the improvement comprising:

an interior wall extending from a first end connected to said perimeter weighting element adjacent said body heel portion through said primary cavity between said top rail and said sole to a second end connected to said perimeter weighting element adjacent the body toe portion defining a secondary cavity within said primary cavity, said interior wall having a height dimension that varies between said first and second ends thereof with said height dimension being greater at said second end than at said first end; and

a weight adjustment member disposed in said secondary cavity.

5. In the iron type golf club head of claim 4, wherein said weight adjustment member comprises a top surface, a bottom surface, and a side surface extending between said top and bottom surfaces, and wherein a groove formed in said side surface extends peripherally of said weight adjustment member.

6. In the iron type golf club head of claim 5, wherein adhesive is applied to said bottom surface of said weight adjustment member in order to secure said weight adjustment member in said secondary cavity, and wherein any excess adhesive collects in said groove when said weight adjustment member is inserted in said secondary cavity.
