Iron type golf club head with low profile tuning port

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 hosel is connected to the heel portion of the body. 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 connected to the perimeter weighting element adjacent the body heel portion through the primary cavity between the top rail and the sole to a second end connected to the perimeter weighting element adjacent the body toe portion to define an elongated secondary cavity or tuning port within the primary cavity. The interior wall is integrally formed on a bottom surface of the primary cavity and extends from the bottom surface of the primary cavity in a direction that is substantially perpendicular to the longitudinal axis of the hosel. This orientation of the interior wall provides the secondary cavity, i.e. the tuning port, with a low profile while also moving the center of gravity of the club head lower and farther away from the front face.

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 hosel connected to the heel portion of said body, said hosel having a. longitudinal axis;    a perimeter weighting element protruding rearwardly from said front face defining a primary cavity in said back face, said primary cavity having a bottom surface, 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 the 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 the perimeter weighting element adjacent the body toe portion defining an elongated secondary cavity within said primary cavity; and    said interior wall being integrally formed on said bottom surface of said primary cavity and extending from said bottom surface of said primary cavity in a direction that is substantially perpendicular to the longitudinal axis of said hosel thereby forming an included acute angle between said interior wall and said bottom surface of said cavity.    
   
   
       2 . The iron type golf club head of  claim 1 , wherein said interior wall has a height dimension that varies between said first and second ends thereof.  
   
   
       3 . The iron type golf club head of  claim 2 , wherein the height dimension of said interior wall is greater at said second end than at said first end.  
   
   
       4 . The iron type golf club head of  claim 1 , further comprising a weight adjustment member disposed in said secondary cavity.  
   
   
       5 . The iron type golf club head of  claim 4 , wherein said weight adjustment member is selected from a plurality of weight adjustment members of different weights.
