Low drag golf club head with improved mass properties
First Claim
Patent Images
1. A golf club head comprising:
- a ball-striking face;
a crown extending back from a top of the ball-striking face;
a sole extending back from a bottom of the ball-striking face and meeting the crown to define a trailing edge at a height between 44% and 56% of a height of the golf club head when at address, such that an amount of work required to achieve a golf club swing speed of 100 mph is less than or equal to 6 joules; and
a strut protruding downwards from an aft of the sole with a weight of about 11 g/cm{circumflex over (
)}3 density pendant from the sole at an end of the strut, by which means a club head center of gravity is located within 3 millimeters of an idealized axis passing through a center of and normal to the ball striking face.

Abstract
This disclosure describes golf club heads with optimized aerodynamics, in which a highly-lifted trailing edge minimizes drag, and in which a protruding element optimizes a location of a club head center of gravity. Features of the disclosure reduce drag forces on a club head during a golf swing and consequently reduce the work required to move the club head through the air. Thus, the club heads allow golfers to achieve faster golf swing velocities and increase golf shot distances.

8. A golf club head comprising:
-
a ball-striking face; a crown and a sole both extending back from a top of the ball-striking face and meeting at a trailing edge at a height between 44% and 56% of a height of when the club head at address, such that an amount of work required to achieve a golf club swing speed greater than or equal to 100 mph is less than or equal to 6 joules; and a weight pendant from an aft section of the sole and connected to the aft section of the sole via a protruding strut such that a club head center of gravity is located within at most 3 mm of an idealized axis passing through a center of and normal to the ball-striking face.
