Multi-piece golf club head
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.
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 a density of said first material is greater than a density of said second material,
wherein no portion of said striking face component is located beyond more than about 30.0 mm from said leading edge, measured along a z-axis,
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, And
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,
Upper Extension Overlap Ratio=Upper Frontal Overlap Distance d 3 /Upper Rear Overlap Distance d 4 .
2. The golf club head of claim 1 , 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.
3. 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.
4. The golf club head of claim 1 , 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.
5. The golf club head of claim 4 , 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.
6. The golf club head of claim 1 , 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,
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 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 and about 2.4, said Upper Extension Overlap Ratio defined as,
