Abstract

Embodiments of golf club face plates with internal cell lattices are presented herein. Other examples and related methods are also disclosed herein.

First claim

The invention claimed is:

1. A cell lattice comprising:
an inner skin;
an outer skin;
a plurality of walls having:
a plurality of axes extending centrally through the plurality of walls between the inner skin and the outer skin, wherein the plurality of walls extend from the axes at an angle less than or equal to approximately 45 degrees; and
a wall thickness that varies relative to position from the inner skin and the outer skin;

a plurality of cells defined by the plurality of walls, the plurality of cells positioned between the inner skin and the outer skin; and
a plurality of apertures for removal of excess material in the cell lattice, the plurality of apertures including at least a first aperture positioned near a center of the cell lattice and remaining apertures positioned around a perimeter of the cell lattice,

wherein the plurality of apertures is positioned through the inner skin of the cell lattice or through the outer skin of the cell lattice.

2. The cell lattice of claim 1 , wherein the wall thickness is greater near the inner skin and the outer skin than near a central region of the cell lattice.

3. The cell lattice of claim 1 , wherein a minimum wall thickness ranges from 0.005 inches to 0.2 inches.

4. The cell lattice of claim 1 , wherein a maximum cell width ranges from 0.005 inches to 0.2 inches.

5. The cell lattice of claim 1 , wherein the thickness of the plurality of walls varies defining a plurality of hourglass shapes.

6. The cell lattice of claim 1 , wherein a center-to-center distance between adjacent axes ranges from 0.005 inches to 0.2 inches.

7. The cell lattice of claim 1 , wherein the plurality of axes are positioned radially from a center of a faceplate.

8. The cell lattice of claim 1 , wherein a diameter of the plurality of apertures ranges from approximately 0.005 inches to 0.2 inches.

9. The cell lattice of claim 1 , wherein each of the plurality of apertures are spaced apart from the remaining apertures by a distance greater than or equal to two times a diameter of the plurality of apertures.
