Abstract
A multi-piece, multi-material golf club head is disclosed herein. More specifically, the golf club head in accordance with the present invention utilizes multiple pieces of different materials to form a frontal portion of a golf club head, allowing more of the frontal portion of the golf club head to be made out of a lightweight material to match the lightweight material of the aft body of the golf club head.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A golf club head comprising:
a striking face component, having a return portion, located at a frontal portion of said golf club head, adapted to strike a golf ball,
wherein said striking face component is made out of a first material,
wherein said striking face component forms a leading edge of said golf club head,
a lightweight face return extension, adapted to engage an aft portion of said striking face component,
wherein said lightweight face return extension is made out of a second material, and
a rear lightweight aft body, adapted to engage an aft portion of said lightweight face return extension,
wherein said rear lightweight aft body is made out of said second material,
wherein a density of said first material is greater than a density of said second material, wherein said golf club head has an Upper Extension Overlap Ratio of between about 1.2 and about 1.8, said Upper Extension Overlap Ratio defined as,

.
2 . The golf club head of claim 1 , wherein no portion of said striking face component is located beyond more than about 30.0 mm from said leading edge, measured along said z-axis.
3 . The golf club head of claim 2 , wherein no portion of said striking face component is located beyond more than about 27.5 mm from said leading edge, measured along said z-axis.
4 . The golf club head of claim 2 , wherein no portion of said striking face component is located beyond more than about 25 mm from said leading edge, measured along said z-axis.
5 . The golf club head of claim 1 , wherein said Upper Extension Overlap Ratio is between about 1.2 and about 1.8.
6 . The golf club head of claim 5 , wherein said Upper Extension Overlap Ratio is about 1.4.
7 . The golf club head of claim 1 , wherein said golf club head has a Lower Extension Overlap Ratio of between about 1 and about 2.4, said Lower Extension Overlap Ratio defined as,

8 . The golf club head of claim 7 , wherein said Lower Extension Overlap Ratio is between about 1.2 and about 1.8.
9 . The golf club head of claim 8 , wherein said Lower Extension Overlap Ratio is about 1.4.
10 . A golf club head comprising:
a striking face component, having a return portion, located at a frontal portion of said golf club head, adapted to strike a golf ball,
wherein said striking face component is made out of a first material,
wherein said striking face component forms a leading edge of said golf club head, and
wherein said striking face component depth distance is less than about 30.0 mm, measured from said leading edge, along a x-axis,
a lightweight face return extension, adapted to engage an aft portion of said striking face component,
wherein said lightweight face return extension is made out of a second material, and
wherein a rearmost portion of said lightweight face return extension is located at a distance of greater than about 40.0 mm away from said leading edge, measured along said z-axis,
a rear lightweight aft body, adapted to engage an aft portion of said lightweight face return extension,
wherein said rear lightweight aft body is made out of said second material, wherein a density of said first material is greater than a density of said second material.
11 . The golf club head of claim 10 , wherein said striking face component depth distance is less than about 27.5 mm, measured from said leading edge, along said z-axis.
12 . The golf club head of claim 11 , wherein said striking face component depth distance is less than about 25 mm, measured from said leading edge, along said z-axis.
13 . The golf club head of claim 10 , wherein said rearmost portion of said lightweight face return extension is located at a distance of greater than about 42.5 mm away from said leading edge, measured along said z-axis.
14 . The golf club head of claim 13 , wherein said rearmost portion of said lightweight face return extension is located at a distance of greater than about 45.0 mm away from said leading edge, measured along said z-axis.
15 . The golf club head of claim 10 , wherein an upper portion of an interface between said striking face component and said lightweight face return extension has an upper frontal overlap distance of between about 8.0 mm to about 12.0 mm.
16 . The golf club head of claim 15 , wherein said upper frontal overlap distance is between about 9.0 mm to about 11.0 mm.
17 . A golf club head comprising:
a striking face component, having a return portion, located at a frontal portion of said golf club head, adapted to strike a golf ball,
wherein said striking face component is made out of a first material,
wherein said striking face component forms a leading edge of said golf club head,
a lightweight face return extension, adapted to engage an aft portion of said striking face component,
wherein said lightweight face return extension is made out of a second material, and
a rear lightweight aft body, adapted to engage an aft portion of said lightweight face return extension,
wherein said rear lightweight aft body is made out of said second material,
wherein a density of said first material is greater than a density of said second material, wherein an upper portion of an interface between said striking face component and said lightweight face return extension has an upper frontal overlap distance of between about 8.0 mm to about 12.0 mm, and wherein a lower portion of an interface between said striking face component and said lightweight face return extension has a lower fontal overlap distance of between about 8.0 mm to about 12.0 mm.
18 . The golf club head of claim 17 , wherein said upper frontal overlap distance is between about 9.0 mm to about 11.0 mm, and
wherein said lower frontal overlap distance is between about 9.0 mm to about 11.0 mm.
19 . The golf club head of claim 18 , wherein said upper frontal overlap distance is about 10.0 mm, and
wherein said lower frontal overlap distance is about 10.0 mm.
20 . The golf club head of claim 17 , wherein said golf club head has an Upper Extension Overlap Ratio of between about 1.2 and about 1.8, said Upper Extension Overlap Ratio defined as,
