Abstract

Claims (34)

1. A golf club head, comprising:

a body including a topline, a sole, and a front face, wherein the front face defines a rear surface that extends along a plane and the body defines a center of gravity plane, wherein the center of gravity plane extends parallel to a ground plane at a center of gravity of the body when the golf club head is at address; and

a lattice structure formed on a portion of the body, layer by layer, via an additive manufacturing process, wherein the portion of the body is bounded by the plane, the center of gravity plane, the topline, and an intersection between the plane and the center of gravity plane, wherein the entire lattice structure is disposed above the center of gravity plane and behind the rear surface, wherein the lattice structure extends along the topline toward a toe end of the body, and wherein a thickness is measured normal to the front face between the front face and a back of the lattice structure, the thickness being smaller in a region proximate the topline and larger in a region proximate the center of gravity plane.

2. The golf club head of claim 1 , wherein the body is fabricated via the additive manufacturing process, and

wherein the additive manufacturing process is a binder jetting process.

3. The golf club head of claim 1 , wherein the lattice structure forms a part of the body.

4. The golf club head of claim 1 , wherein, in an assembled configuration, the lattice structure is visible from an exterior of the golf club head.

5. The golf club head of claim 1 , wherein the lattice structure includes a plurality of unit cells that vary in at least one of a unit cell size or a unit cell shape.

6. The golf club head of claim 5 , wherein an upper region of the body is entirely above the center of gravity plane, a lower region of the body is entirely below the center of gravity plane, and the lower region has a density that is greater than a density of the upper region.

7. A golf club head, comprising:

a body including a topline, a sole, and a front face, wherein the body defines a center of gravity plane, wherein the center of gravity plane is defined as a plane that extends parallel to a ground plane at a center of gravity of the body when the golf club head is at address; and

a lattice structure formed within a portion of the body, layer by layer, via an additive manufacturing process,

wherein the center of gravity plane divides the body into a first region that includes the topline and a second region that includes the sole,

wherein the lattice structure is arranged in the first region above the center of gravity plane and adjacent a toe end,

wherein the second region of the body is below the center of gravity plane and has a density that is greater than a density of the first region,

wherein the lattice structure includes a plurality of interior voids that are in fluid communication with at least one void that is formed through an exterior surface on a toe end of the golf club head, and

wherein, in an assembled configuration, the lattice structure is visible from an exterior of the golf club head.

8. The golf club head of claim 7 , wherein the front face defines a rear surface that extends along a rear plane, and

wherein the portion of the body is bounded by the rear plane, the center of gravity plane, and an intersection between the rear plane and the center of gravity plane.

9. The golf club head of claim 8 , wherein the entire body above the center of gravity plane and rearward of the rear plane includes the lattice structure.

10. The golf club head of claim 7 , wherein the lattice structure and the body are formed from the same metal and are integral with one another.

11. The golf club head of claim 7 , wherein at least a portion of the lattice structure is covered by a solid material of the body.

12. A golf club head, comprising:

a body including a topline, a sole, and a front face, wherein the body defines a center of gravity plane, wherein the center of gravity plane is defined as a plane that extends parallel to a ground plane at a center of gravity of the body when the golf club head is at address; and

a lattice structure formed within a portion of the body, layer by layer, via an additive manufacturing process,

wherein the lattice structure is arranged above the center of gravity plane and extends along an exterior of the topline from a heel end to a toe end of the body,

wherein, in an assembled configuration, a portion of the lattice structure is visible from an exterior of the golf club head, and

wherein a thickness is measured normal to the front face between the front face and a back of the lattice structure, the thickness being smaller in a region proximate the topline and larger in a region proximate the center of gravity plane.

13. The golf club head of claim 12 , wherein the front face defines a rear surface that extends along a rear plane, and

wherein the portion of the body is bounded by the rear plane, the center of gravity plane, and an intersection between the rear plane and the center of gravity plane.

14. The golf club head of claim 13 , wherein an entire region of the body that is disposed above the center of gravity plane and rearward of the rear plane includes the lattice structure.

15. The golf club head of claim 12 , wherein the lattice structure and the body are formed from the same metal and are integral with one another.

16. The golf club head of claim 12 , wherein the lattice structure is visible to a user when the golf club head is at address.

17. The golf club head of claim 12 , wherein the lattice structure includes a plurality of unit cells that vary in at least one of a unit cell size or a unit cell shape.
