Patent Images
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.

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)
