Abstract
Official abstract text for this publication.
A golf club head formed of an alloy of steel that is capable of improving the center of gravity (CG) location while maintaining traditional external dimensions of the golf club head. More specifically, the golf club head in accordance with the present invention achieves a relatively low CG while maintaining traditional external dimensions by reducing the amount of mass contributed by the crown, the striking face, and the hosel, and strategically reallocating this mass within and/or proximate the sole of the golf club head.
First claim
Opening claim text (preview).
What is claimed is: 1. A golf club head comprising: a striking face that defines a face center, a crown, as sole opposite said crown, a heel, a toe opposite said heel, and a hosel adjacent said heel and configured to join said golf club head to a shaft, wherein an X-axis is defined as a horizontal axis tangent to said face center of said striking face with a positive direction towards said heel of said golf club head, a Y-axis is a vertical axis orthogonal to said X-axis with a positive direction towards said crown of said golf club head, and a Z-axis being orthogonal to both said X-axis and said Y-axis with a positive direction towards a front of said golf club head, wherein an origin of said X-axis, said Y-axis, and said Z-axis is centered at a center of gravity (CG) of said golf club head, wherein said crown has a minimum crown thickness of between about 0.3 mm and about 0.6 mm, wherein a mass of said golf club head below an X-Z plane set at a vertical height from said ground plane equal to 25% of said peak crown height measurement is greater than about 45% of a total mass of said golf club head. 2. The golf club head of claim 1 , wherein said golf club head has a peak crown height of greater than about 35.0 mm. 3. The golf club head of claim 2 , wherein said golf club head has a ground to top face radius measurement of greater than or equal to about 31.0 mm. 4. The golf club head of claim 3 , wherein said golf club head has a CG-Yg, being a distance from a ground plane to said CG along said Y-axis, of less than about 16.0 mm. 5. The golf club head of claim 4 , wherein said golf club head has a ΔYccg of between about 22.0 mm and about 28.0 mm, said ΔYccg defined by the equation below: Δ Yccg =Peak Crown Height (mm)− CG - Yg (mm). 6. The golf club head of claim 5 , wherein said golf club head has a Maximum Sole Thickness of Minimum Crown Thickness Ratio of greater than or equal to about 4.0, said Maximum Sole Thickness to Minimum Crown Thickness Ratio defined by the equation below: Maximum Sole Thickness to Minimum Crown Thickness Ratio = Maximum Sole Thickness Minimum Crown Thickness . 7. The golf club head of claim 1 , wherein a mass of said golf club head below said X-Z plane set at a vertical height from said ground plane equal to 20% of said peak crown height measurement is greater than about 38% of said total mass of said golf club head. 8. The golf club head of claim 1 , wherein a mass of said golf club head below said X-Z plane set at a vertical height from said ground plane equal to 15% of said peak crown height measurement is greater than about 27% of said total mass of said golf club head. 9. The golf club head of claim 1 , wherein a mass of said golf club head below said X-Z plane set at a vertical height from said ground plane equal to 10% of said peak crown height measurement is greater than about 12% of said total mass of said golf club head. 10. A golf club head comprising: a striking face that defines a face center, a crown, as sole opposite said crown, a heel, a toe opposite said heel, and a hosel adjacent said heel and configured to join said golf club head to a shaft, wherein an X-axis is defined as a horizontal axis tangent to said face center of said striking face with a positive direction towards said heel of said golf club head, a Y-axis is a vertical axis orthogonal to said X-axis with a positive direction towards said crown of said golf club head, and a Z-axis being orthogonal to both said X-axis and said Y-axis with a positive direction towards a front of said golf club head, wherein an origin of said X-axis, said Y-axis, and said Z-axis is centered at a center of gravity (CG) of said golf club head, wherein said golf club head has a volume of between about 100 cc and about 200 cc, wherein said golf club head has a top face radius measurement of between about 31.0 mm and about 37.0 mm, wherein said golf club head has a Maximum Sole Thickness of Minimum Crown Thickness Ratio of greater than or equal to about 4.0, said Maximum Sole Thickness to Minimum Crown Thickness Ratio defined by the equation below: Maximum Sole Thickness to Minimum Crown Thickness Ratio = Maximum Sole Thickness Minimum Crown Thickness 11. The golf club head of claim 10 , wherein a mass of said golf club head below said X-Z plane set at a vertical height from said ground plane equal to 10% of said peak crown height measurement is greater than about 12% of said total mass of said golf club head. 12. The golf club head of claim 11 , wherein a mass of said golf club head below said X-Z plane set at a vertical height from said ground plane equal to 15% of said peak crown height measurement is greater than about 27% of said total mass of said golf club head. 13. The golf club head of claim 12 , wherein a mass of said golf club head below said X-Z plane set at a vertical height from said ground plane equal to 20% of said peak crown height measurement is greater than about 38% of said total mass of said golf club head. 14. The golf club head of claim 13 , wherein a mass of said golf club head below an X-Z plane set at a vertical height from said ground plane equal to 25% of said peak crown height measurement is greater than about 45% of a total mass of said golf club head. 15. The golf club head of claim 14 , said golf club head has a top face radius measurement of between about 33.0 mm and about 35.0 mm. 16. A golf club head comprising: a striking face that defines a face center, a crown, as sole opposite said crown, a heel, a toe opposite said heel, and a hosel adjacent said heel and configure
