Abstract

A golf club head made of a suitable metal such as stainless steel includes a hollow body and a hosel. The hollow body has a top wall, a bottom wall, a side wall, and a front wall with a face arranged for impacting golf balls. The hollow body has a weight pad which provides the golf club head with increased resistance to rotation or twisting upon impact with golf balls at off-center points on the face. The weight pad weighs between 5 and 15 grams and is located in the heel portion of the body. The weight pad is elongated in a direction extending along a length dimension of the body side wall.

Claims

1. A golf club head having a center of gravity, said golf club head comprising:

a hollow body having a heel portion, a toe portion, a top wall, a bottom wall, a side wall between said top and bottom walls, a front wall with a face for impacting a golf ball;

a hosel for receiving one end of an elongated shaft;

said face having a sweet spot thereon aligned with the center of gravity so that when a golf ball is impacted at said sweet spot no rotation of the club head will occur, said face being disposed forwardly of an inclined with respect to a first vertical plane containing a longitudinal axis of the elongated shaft, said face intersecting and being substantially perpendicular to a second vertical plane containing the center of gravity, said second vertical plane dividing said body into said heel and toe portions;

a weight pad disposed along said side wall in the heel portion of the body rearwardly of said first vertical plane and intermediate said hosel and said second vertical plane, said weight pad providing the golf club head with increased resistance to horizontal rotation about a vertical axis that extends through the center of gravity when the club head impacts a golf ball on the face at off-center points spaced laterally of the sweet spot;

said side wall having a length dimension measured between said first vertical plane and a third vertical plane which is disposed generally parallel to said first vertical plane while being located rearwardly of both said front wall and said hosel, said third vertical plane containing a rearwardmost point on said side wall, said weight pad being elongated in a direction extending along the length dimension of said side wall; and

said weight pad being divided into two substantially equal parts by a fourth vertical plane which intersects the first and second vertical planes at approximately 45 degrees.

2. The golf club head of claim 1, wherein said weight pad weighs between 5 and 15 grams.

3. The golf club head of claim 1, wherein said hollow body is formed of metal.

4. The golf club head of claim 3, wherein said hollow body is formed of stainless steel.

5. The golf club head of claim 1, wherein said first, second and fourth vertical planes intersect at a common axis.

6. The golf club head of claim 1, wherein said top, bottom and side walls each have a thickness between 0.036 and 0.040 inch, and wherein said front wall has a thickness between 0.128 and 0.135 inch.
