CG height adjustability by conformal crown weighting
View Patent ↗A golf club head comprising a crown with an edge support structure and a flexible, conformal weight sized to fit within the edge support structure is disclosed herein. The edge support structure preferably is disposed on an internal surface of the crown so that the conformal weight is invisible when the golf club head is viewed at address. The conformal weight can be removed to adjust the vertical center of gravity of the club head, and preferably is oriented in a front-to-back direction along the club head's X-axis. The conformal weight preferably is composed of a high-density polymeric material with a specific gravity ranging from 1.8 to 4.2.
1. A golf club head comprising:
a face component comprising a face component contact surface;
a sole;
a crown; and
a flexible weight comprising a first front edge, a width, a length, a rear edge, and at least one cutout,
wherein the flexible weight comprises a polymer having a specific gravity value of 1.8 to 4.2,
wherein at least one of the sole and the crown comprises a second front edge, an aft edge, and an edge support structure,
wherein the flexible weight is retained within the edge support structure, wherein a damping layer is disposed between the flexible weight and an interior surface of the crown or the sole, and
wherein the length of the flexible weight is greater than the width of the flexible weight.
2. The golf club head of claim 1 , wherein the first front edge abuts one of the second front edge and the face component contact surface when the weight is fully engaged within the edge support structure.
3. The golf club head of claim 1 , wherein at least one of the crown and the sole comprises at least one weight port.
4. The golf club head of claim 1 , wherein at least one of the crown and the sole is composed of composite and comprises a doubly curved shallow shell structure.
5. The golf club head of claim 1 , wherein the flexible weight is aligned with a golf club head X-axis when the flexible weight is engaged with the edge support structure.
6. The golf club head of claim 1 , wherein the edge support structure is integrally formed with at least one of the crown and the sole.
7. The golf club head of claim 1 , further comprising an aft opening in communication with the edge support structure, wherein the aft opening is sized to receive the flexible weight.
8. The golf club head of claim 1 , wherein the edge support structure is selected from the group consisting of internal rails, an internal enclosed support structure, and external rails.
9. The golf club head of claim 8 , wherein the edge support structure is internal rails, and wherein at least one of the sole and the crown comprises an opening disposed over the internal rails to form an external channel.
10. The golf club head of claim 1 , wherein the weight front edge has shape selected from the group consisting of rectangular, tapered, and rounded.
11. The golf club head of claim 1 , wherein the flexible weight comprises a plurality of cutouts.
12. The golf club head of claim 11 , wherein each of the cutouts is disposed at an edge of the flexible weight.
13. The golf club head of claim 1 , wherein the flexible weight has an initial un-deformed shape comprising a curvature that matches a curvature of the crown or the sole.
14. A golf club head comprising:
a face component comprising a face component contact surface;
a sole comprising a sole aft edge, an internal surface, and an edge support structure disposed on the internal surface;
a weight composed of a polymeric material; and
a fastener,
wherein the edge support structure is integrally formed with the sole,
wherein the weight comprises a rectangular shape,
wherein the weight is removably retained within the edge support structure, and
wherein the weight is compressed between the fastener and the face component contact surface.
15. The golf club head of claim 14 , wherein the weight is hidden from view when it is fully engaged with the edge support structure.
16. The golf club head of claim 14 , wherein the weight comprises a plurality of weight protrusions.
17. The golf club head of claim 14 , wherein the weight comprises a thick-edged cross-sectional shape.
18. The golf club head of claim 14 , wherein the weight comprises a plurality of cutouts.
19. The golf club head of claim 14 , further comprising a damping layer disposed between the flexible weight and an interior surface of the sole.
