Head profile for a golf iron

Abstract

The head of a golf iron having an improved profile that enables a golfer to accurately align the club head with a golf ball so that the club head will strike the ball at the sweet spot located on the club face. The club head has a top edge which runs above the club face and includes first and second portions that extend in first and second directions. The boundary line between the first and second portions at the top edge of the club head lies in a vertical sweet spot reference plane with the center of the sweet spot. The boundary line at the top edge of the club head is visible to the golfer looking down at his club head so as to provide the golfer with an indication of the location of the sweet spot on the club face at which to strike the golf ball during his swing.

1 . A golf club head attached to a hosel and comprising a face at which a golf ball is to be struck, a sweet spot located on the face at which to apply an impact force to the golf ball when the golf club head is swung towards the golf ball, an inside end at which the hosel is attached, an outside end located opposite the inside end, and a top edge which runs above the face of the club head between the inside and outside ends thereof, said top edge having a first portion which runs in a first direction and a second portion which runs in a second direction. 
     
     
         2 . The golf club head recited in  claim 1 , wherein there is a perceptively visible boundary line lying between the first and second portions of said top edge which run in said first and second directions, said visible boundary line being aligned with the center of the sweet spot located on the face of said club head. 
     
     
         3 . The golf club head recited in  claim 2 , wherein said visible boundary line is located in a vertical sweet spot reference plane with the center of the sweet spot that is located on the face of said club head. 
     
     
         4 . The golf club head recited in  claim 3 , further comprising a plurality of parallel spin control grooves formed in and extending horizontally across the face of said club head, said vertical sweet spot reference plane in which said visible boundary line and the center of the sweet spot are located lying in perpendicular alignment with the horizontally extending spin control grooves. 
     
     
         5 . The golf club head recited in  claim 4 , wherein the first portion of said top edge inclines upwardly in said first direction between the hosel at the inside end of said club head and the vertical sweet spot reference plane in which said visible boundary line is located, and the second portion of said top edge extends horizontally in said second direction between said sweet spot reference plane and the outside end of said club head. 
     
     
         6 . The golf club head recited in  claim 5 , wherein the second portion of said top edge which extends horizontally in said second direction lies in parallel alignment with the plurality of horizontally extending spin control grooves formed in and extending across the face of the club head. 
     
     
         7 . The golf club head recited in  claim 5 , wherein each of the upwardly inclined first portion and the horizontally extending second portion of said top edge runs continuously in a straight line path. 
     
     
         8 . A golf club head attached to a hosel and comprising a face at which a golf ball is to be struck, a sweet spot located on the face at which to apply an impact force to the golf ball when the golf club head is swung towards the golf ball, an inside end at which the hosel is attached, an outside end located opposite the inside end, and a top edge which runs above the face of the club head between the inside and outside ends thereof, said top edge having a first portion that extends in a straight line in a first direction and a second portion that extends in a straight line in a second direction and lies adjacent said first portion, such that the first and second straight line portions of said top edge are aligned with one another to form an angle, and wherein a perceptively visible boundary line is located at the intersection of said first and second straight line portions. 
     
     
         9 . The golf club head recited in  claim 8 , wherein the visible boundary line located at the intersection of the first and second straight line portions of said top edge is aligned with the center of the sweet spot located on the face of said club head. 
     
     
         10 . The golf club head recited in  claim 9 , wherein said visible boundary line is located in a vertical sweet spot reference plane with the center of the sweet spot that is located on the face of said club head. 
     
     
         11 . The golf club head recited in  claim 10 , further comprising a plurality of parallel spin control grooves formed in and extending horizontally across the face of said club head, said vertical sweet spot reference plane in which said visible boundary line and the center of the sweet spot are located lying in perpendicular alignment with the horizontally extending spin control grooves. 
     
     
         12 . The golf club head recited in  claim 11 , wherein the first portion of said top edge is inclined upwardly in said first direction and the second portion of said top edge extends horizontally in said second direction so as to lie in parallel alignment with the horizontally extending spin control grooves. 
     
     
         13 . The golf club head recited in  claim 11 , wherein the first portion of said top edge inclines upwardly in said first direction and the second portion of said top edge declines downwardly in said second direction.
