Golf club heads with protrusion weights and related methods
First Claim
1. A golf club head comprising:
- a body comprising;
a crown portion, a sole portion, a heel portion, a toe portion, a rear portion, a front portion comprising a club face, and a geometric center; and
a protrusion weight protruded from the body;
wherein;
if the body comprises a skirt portion, the protrusion weight protrudes from the heel portion and at least one of the sole portion or the skirt portion of the body;
if the body lacks the skirt portion, the protrusion weight protrudes from the heel portion and the sole portion of the body;
a center of gravity of the golf club head is defined by both a mass of the body and a mass of the protrusion weight;
a center of gravity of the body is defined by the mass of the body independent of the mass of the protrusion weight;
a center of gravity of the protrusion weight is defined by the mass of the protrusion weight independent of the mass of the body, and is external to a body volume of the body of the golf club head;
a moment of inertia of the golf club head is increased due to a distance extension of a distance between the center of gravity of the protrusion weight and the center of gravity of the golf club head, the distance extension being external to the body volume;
the center of gravity of the golf club head is located at the heel portion of the body, shifted by the protrusion weight away from the toe portion and away from the center of gravity of the body; 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 body and a protrusion weight protruded from a heel, a sole, and/or a skirt of the body. A center of gravity of the protrusion weight can be external to the body of the golf club head. A moment of inertia of the golf club head can be increased due to a distance extension between the center of gravity of the protrusion weight and a center of gravity of the golf club head, the distance extension being external to the body. The center of gravity of the golf club head can be located at a heel portion of the body, shifted by the protrusion weight away from a toe portion of the body and from a center of gravity of the body. The protrusion weight can be at least partially visible from an exterior of the golf club head. Other examples are disclosed herein.

15. A method for providing a golf club head, the method comprising:
-
providing a body of the golf club head; and providing a protrusion weight protruding from the body of the golf club head; wherein; providing the body of the golf club head comprises; providing a crown portion, a sole portion, a toe portion, a heel portion, a rear portion, and a front portion comprising a club face; and providing a center of gravity of the body defined by a mass of the body independent of a mass of the protrusion weight; providing the protrusion weight comprises; if the body comprises a skirt portion; providing the protrusion weight to protrude from the heel portion and from at least one of the sole portion, or the skirt portion of the body; if the body lacks the skirt portion; providing the protrusion weight to protrude from the heel portion and from the sole portion of the body; providing a center of gravity of the golf club head defined by both the mass of the body and the mass of the protrusion weight; providing a center of gravity of the protrusion weight defined by the mass of the protrusion weight independent of the mass of the body, and external to the body of the golf club head; providing the protrusion weight to be at least partially visible from an exterior of the body; locating the center of gravity of the golf club head at the heel portion, shifted by the protrusion weight away from the center of gravity of the body and away from a geometric center of the body; and providing a moment of inertia of the golf club head to be increased due to a distance extension of a distance between the center of gravity of the protrusion weight and the center of gravity of the golf club head, the distance extension being external to a volume of the body. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)

23. A golf club head comprising:
-
a club head body comprising; a crown portion, a sole portion, a rear portion, a front portion comprising a club face, a heel portion, a toe portion, and a geometric center; and a protrusion weight protruded from the club head body; wherein; the protrusion weight is at least partially visible from an address position viewpoint and is at least partially external to the club head body; if the club head body comprises a skirt portion, the protrusion weight protrudes from the heel portion and at least one of the sole portion or the skirt portion of the club head body; if the club head body lacks the skirt portion, the protrusion weight protrudes from the heel portion and the sole portion of the club head body; a center of gravity of the golf club head is defined by both a mass of the club head body and a mass of the protrusion weight; a center of gravity of the club head body is defined by the mass of the club head body independent of the mass of the protrusion weight; a center of gravity of the protrusion weight is defined by the mass of the protrusion weight independent of the mass of the club head body, and is external to a contour of the club head body; the center of gravity of the golf club head is located at the heel portion of the club head body, shifted by the protrusion weight away from the toe portion and away from the geometric center of the club head body; a moment of inertia of the golf club head is increased due to a distance extension of a distance between the center of gravity of the protrusion weight and the center of gravity of the club head body, the distance extension being external to a volume of the club head body; the club head body comprises a compass plane defined by; a heel-to-toe axis extending through the geometric center; and a front-to-rear axis extending through the geometric center; and with respect to the address position viewpoint; a toe-end of the heel-to-toe axis is at zero degrees with respect to the compass plane; and
the center of gravity of the protrusion weight is located between approximately 120 degrees and approximately 180 degrees with respect to the compass plane. - View Dependent Claims (24, 25, 26, 27)
