Abstract

Aspects of this disclosure relate to a golf club head which includes a wood type golf club head body including a ball striking face portion at a front side thereof, a rear side opposite the front side, a crown portion, and a sole portion. Further, the sole or crown or rear portion of the golf club head body may be configured so that the golf club head body includes a bump portion which protrudes from the sole or crown or rear portion and an indented portion which recedes into the sole or crown or rear portion and creates a recess in the sole or crown or rear portion of the golf club head body. Further, the bump portion and the indented portion may be configured so that a center of gravity of the club head body is nearer to one of the heel edge of the club head body and the toe edge of the club head body.

Claims

1. A golf club head comprising:

a hollow wood type golf club head body including a ball striking face portion at a front side thereof, a rear side opposite the front side, a crown portion, and a sole;

wherein the sole consists of an exaggerated depth portion, a non-exaggerated depth portion, and a generally linear, sloped boundary portion, the exaggerated depth portion and the non-exaggerated depth portion separated by the generally linear, sloped boundary portion wherein the thickness of the sole of the golf club head changes, and wherein the sloped boundary portion extends across the sole from a point proximate to the rear side to a point proximate to the ball striking face portion;

wherein the sole of the golf club head has a wall thickness in the exaggerated depth portion that is greater than a wall thickness of the sole of the golf club head in the non-exaggerated depth portion;

wherein a first area of the exaggerated depth portion is within a range of 80% to 120% of a second area of the non-exaggerated depth portion;

wherein the entire exaggerated depth portion and the entire non-exaggerated depth portion are positioned on opposite sides of the sloped boundary portion; and

wherein the majority of a volume and the majority of a mass of the club head body are nearer to the exaggerated depth portion than to the non-exaggerated depth portion.

2. The golf club head according to claim 1, wherein a center of gravity of the club head body is nearer to the exaggerated depth portion than to the non-exaggerated depth portion.

3. The golf club head according to claim 1, wherein the exaggerated depth portion is located in a rear toe quadrant of the golf club head.

4. The golf club head according to claim 1, wherein the exaggerated depth portion is located in a rear heel quadrant of the golf club head.
