Golf club heads with protrusion weights and related methods
First Claim
1. A golf club head comprising:
- a head body comprising;
a crown portion, a sole portion, a heel portion with a heel end, a toe portion with a toe end, a rear portion, a front portion comprising a club face, and a geometric center;
anda protrusion weight coupled to the head body;
wherein;
the protrusion weight protrudes from at least the heel portion of the head body and is separated from the toe portion of the head body;
a head center of gravity of the golf club head is defined by both a mass of the head body and a mass of the protrusion weight;
a body center of gravity of the head body is defined by the mass of the head body independent of the mass of the protrusion weight;
a weight center of gravity of the protrusion weight is defined by the mass of the protrusion weight independent of the mass of the head body, and is external to a body volume of the head body of the golf club head; and
the protrusion weight is at least partially visible from an exterior of the golf club head.

Abstract
A golf club head can comprise a head body and a protrusion weight coupled thereto. The protrusion weight can protrude from at least the heel portion of the head body. The head center of gravity of the golf club head can be defined by both a mass of the head body and a mass of the protrusion weight. The body center of gravity of the head body can be defined by the mass of the head body independent of the mass of the protrusion weight. A weight center of gravity of the protrusion weight can be defined by the mass of the protrusion weight independent of the mass of the head body, and can be external to a body volume of the head body. The protrusion weight can be at least partially visible from an exterior of the club head. Other embodiments and related methods are also disclosed herein.

11. A method for providing a golf club head, the method comprising:
-
providing a head body comprising; a crown portion, a sole portion, a heel portion with a heel end, a toe portion with a toe end, a rear portion, a front portion comprising a club face, a hosel, and a geometric center; providing a protrusion weight at the head body; and coupling a golf shaft to the hosel of the head body; wherein; the protrusion weight protrudes from at least the heel portion of the head body and is separated from the toe portion of the head body; a head center of gravity of the golf club head is defined by both a mass of the head body and a mass of the protrusion weight; a body center of gravity of the head body is defined by the mass of the head body independent of the mass of the protrusion weight; a weight center of gravity of the protrusion weight is defined by the mass of the protrusion weight independent of the mass of the head body, and is external to a body volume of the head body of the golf club head; the geometric center of the head body defines a center of a compass plane that, from a top view of the golf club head, comprises; a heel-to-toe axis extending through the geometric center; a front-to-rear axis extending through the geometric center; and a zero-degree position defined by a toe end of the heel-to-toe axis; and providing the protrusion weight comprises; locating the protrusion weight such that the weight center of gravity is between approximately 120 degrees and approximately 180 degrees with respect to the compass plane. - View Dependent Claims (12, 13, 14, 15)

16. A golf club head comprising:
-
a head body comprising; a crown portion, a sole portion, a heel portion with a heel end, a toe portion with a toe end, a rear portion, a front portion comprising a club face, a hosel, and a geometric center; and a protrusion weight at the head body; wherein; the protrusion weight protrudes from at least the heel portion of the head body and is separated from the toe portion of the head body; a head center of gravity of the golf club head is defined by both a mass of the head body and a mass of the protrusion weight; a body center of gravity of the head body is defined by the mass of the head body independent of the mass of the protrusion weight; a weight center of gravity of the protrusion weight is defined by the mass of the protrusion weight independent of the mass of the head body; the protrusion weight is separated from the hosel of the head body; the head center of gravity is located between the body center of gravity and the heel end, shifted thereto by the weight center of gravity; and a mass of the protrusion weight comprises approximately 3% to approximately 16% of a total mass of the golf club head. - View Dependent Claims (17, 18, 19, 20)
