Abstract
A golf club head having an adjustable weight system. The golf club head having a single, relatively compact slot for receiving a weight assembly. The weight assembly comprising a relatively high mass. Wherein small lateral movements of the heavy weight assembly are sufficient to shape a golfer's shot. Wherein the small movements also prevents the reduction of the total golf club head moment of inertia, thus preserving the forgiveness of the golf club when the ball is miss-hit.
Claims15
A golf club head, comprising:
- a front portion having a strikeface, a crown, a sole, a toe region, a heel region, and a rear portion, which together form a hollow interior;
- wherein the strikeface defines a strikeface geometric center, and a loft plane extends tangent to the strikeface geometric center;
- a coordinate system having a coordinate system origin at the strikeface geometric center, the coordinate system comprising:
- an x-axis extending through the strikeface geometric center from the toe region to the heel region;
- a y-axis extending through the strikeface geometric center in a direction from the crown to the sole;
- and
- a z-axis extending through the strikeface geometric center in a direction from the front portion to the rear portion;
- wherein the x-axis, y-axis, and z-axis are perpendicular to one another;
- a depth of 3.0 inches to 6.0 inches, measured from the loft plane to a rear-most point of the rear portion parallel to the z-axis;
- a single slot in the rear portion, comprising:
- a slot top surface;
- a slot bottom surface;
- a slot height measured between the slot bottom surface and the slot top surface, wherein the slot height varies;
- three weight assembly attachment apertures;
- a slot cross-sectional shape in a toe-to-heel direction that is non-uniform [and defines three slot receptacles associated with the three weight assembly attachment apertures];
- a slot structure mass less than 7.0% of a total mass of the golf club head;
- and
- a moveable weight assembly configured to be positioned within the single slot and releasably affixed to a selected one of the three weight assembly attachment apertures [within an associated weight assembly attachment aperture], the moveable weight assembly comprising a single weight member and a single fastener, wherein the moveable weight assembly has a mass of 16 grams to 50 grams;
- wherein the non-uniform slot cross-sectional shape of the single slot prevents sliding of the moveable weight assembly within the single slot between the three weight assembly attachment apertures.

- a depth of 3.0 inches to 6.0 inches, measured from the loft plane to a rear-most point of the rear portion parallel to the z-axis;
- a single slot in the rear portion, comprising:
- a slot top surface;
- a slot bottom surface;
- a slot height measured between the slot bottom surface and the slot top surface, wherein the slot height varies;
- three weight assembly attachment apertures, wherein each of the three weight assembly attachment apertures is separated from an adjacent weight assembly attachment aperture by an aperture separation distance of 0.5 inch to 0.6 inch;
- a slot aperture housing for each weight assembly attachment aperture;
- a slot interior rib;
- a slot cross-sectional shape in a toe-to-heel direction that is non-uniform;
- a slot structure mass less than 7.0% of a total mass of the golf club head;
- a slot interior surface;
- and
- two slot sidewalls;
- wherein the slot interior surface, slot bottom surface, slot top surface, and two slot sidewalls cooperate to form a slot channel open to the rear portion and sole of the golf club head and a slot structure exposed to the hollow interior;
- and
- wherein the slot bottom surface does not extend as far towards the rear-most point of the rear portion as the slot top surface;
- and
- a moveable weight assembly configured to be positioned within the single slot and releasably affixed to a selected one of the three weight assembly attachment apertures, the moveable weight assembly comprising a single weight member and a single fastener, wherein the single fastener is retained within the single weight member when the moveable weight assembly is detached from the single slot, and wherein the moveable weight assembly has a mass of 16 grams to 50 grams;
- wherein the non-uniform slot cross-sectional shape of the single slot prevents sliding of the moveable weight assembly within the single slot between the three weight assembly attachment apertures.
