Abstract
Golf club heads with ribs are described herein. Other embodiments and related methods are also disclosed herein.
Claims25
A golf club head comprising:
- a body having a heel end, a toe end, a sole, a front surface, and a rear surface;
- and
- a plurality of ribs protruded from a rib surface of the body and comprising:
- a first rib with a first longitudinal axis;
- a second rib with a second longitudinal axis;
- and
- a third rib with a third longitudinal axis;
- wherein:
- the first, second, and third longitudinal axes intersect at a common point external to the body;
- and
- the plurality of ribs are concave relative to a crown of the golf club head.
