Abstract
A golf club head (42) having a substantially square or rectangular body is disclosed herein. The golf club head (42) preferably has a volume ranging from 420 cubic centimeters to 470 cubic centimeters. The golf club head (42) preferably has a moment of inertia about the lzz axis through the center of gravity of the golf club head greater than 4000 grams-centimeters squared, and a moment of inertia about the lxx axis through the center of gravity of the golf club head greater than 3000 grams-centimeters squared.
Claims21
A golf club head comprising:
- a front wall having a perimeter;
- a heel wall extending 2.5 inches to 4.5 inches rearward from the perimeter of the front wall;
- an aft wall substantially perpendicular to the heel wall, the aft wall extending from 2.5 inches to 4.5 inches from an aft edge of the heel wall;
- and
- a toe wall substantially perpendicular to the aft wall, the toe wall extending from 2.5 inches to 4.5 inches from an aft edge of the toe wall.
2 more elements
A golf club head comprising:
- a body having a face, a crown, a sole, a heel wall, an rear wall, and a toe wall,
- wherein the body has a volume ranging from 350 cubic centimeters to 500 cubic centimeters, and
- wherein each of the rear wall, the toe wall and the heel wall is substantially straight.
A golf club head comprising:
- a face component composed of a first material, the face component comprising a striking plate portion and a return portion, the return portion extending a distance ranging from 0.25 inch to 1.5 inches from a perimeter of the striking plate portion;
- and
- a substantially square aft-body coupled to the return portion of the face component, the aft-body composed of a second material having a density less than that of the first material, the aft-body comprising a crown portion, a sole portion, the sole portion having a bottom section and a ribbon section, the ribbon section being located between the crown portion and the bottom section of the sole portion, wherein the golf club head is substantially square.
A golf club head comprising:
- a body comprising a crown, a sole, a ribbon and a striking plate,
- wherein the golf club head has a volume less than 460 cubic centimeters, a mass ranging from 190 grams to 225 grams, a moment of inertia about the lzz axis through the center of gravity of the golf club head greater than 4000 grams-centimeters squared, and a moment of inertia about the lxx axis through the center of gravity of the golf club head greater than 3000 grams-centimeters squared.
A golf club head comprising:
- a face component composed of a first material, the face component comprising a striking plate portion and a return portion, the return portion extending rearward from a perimeter of the striking plate portion;
- and
- an aft-body coupled to the return portion of the face component, the aft-body composed of a second material having a density less than that of the first material, the aft-body comprising a crown portion, a sole portion, the sole portion having a bottom section and a ribbon section,
- wherein the golf club head has a volume less than 460 cubic centimeters, a mass ranging from 190 grams to 225 grams, a moment of inertia about the lzz axis through the center of gravity of the golf club head greater than 4000 grams-centimeters squared, and a moment of inertia about the lxx axis through the center of gravity of the golf club head greater than 3000 grams-centimeters squared.
1 more element
A golf club head comprising:
- a front wall having a perimeter;
- a heel wall extending rearward from the perimeter of the front wall a distance of least 66% of the length of the heel wall at an angle of 80 degrees to 90 degrees relative to a plane parallel to the farthest extent of the front wall;
- an aft wall extending from 2.5 inches to 4.5 inches from an aft edge of the heel wall;
- and
- a toe wall extending rearward from the perimeter of the front wall a distance of least 66% of the length of the toe wall at an angle of 80 degrees to 90 degrees relative to a plane parallel to the farthest extent of the front wall,
- wherein the golf club head has a volume ranging from 420 cubic centimeters to 470 cubic centimeters.
