Abstract

A golf club head is described having a club head portion, a shaft portion connected to the club head portion, and a grip portion connected to the shaft portion. The club head portion has a heel portion, a sole portion, a toe portion, a crown portion, a hosel portion, and a striking face. The striking face has a center face roll contour, a toe side roll contour, a heel side roll contour, a center face bulge contour, a crown side bulge contour, and a sole side bulge contour. The toe side roll contour is more lofted than the center face roll contour. The heel side roll contour is less lofted than the center face roll contour. The crown side bulge contour is more open than the center face bulge contour, and the sole side bulge contour is more closed than the center face bulge contour.

First claim

We claim:

1. A golf club comprising:
a club head portion having a hosel portion, a heel portion, a sole portion, a toe portion, a crown portion, and a striking face having a striking face surface, wherein the striking face has a bulge radius between 228.6 mm and 355.6 mm;
wherein the club head includes at least one weight port and an adjustable weight located in the at least one weight port;
a shaft portion connected to the club head portion;
a sleeve portion connected to the shaft portion, the sleeve portion being capable of adjusting the loft, lie, or face angle of the club head when the sleeve portion is removed from the hosel portion in a first configuration and reinserted into the hosel portion in a second configuration;
a grip portion connected to the shaft portion;
the striking face having a center face location;
a center face vertical plane passing through the center face location, the center face vertical plane extending from adjacent the crown portion to adjacent the sole portion and intersecting with the striking face surface to define a center face roll contour;
a toe side vertical plane being spaced away from the center face vertical plane by 30 mm toward the toe portion, the toe side vertical plane extending from adjacent the crown portion to adjacent the sole portion and intersecting with the striking face surface to define a toe side roll contour;
a heel side vertical plane being spaced away from the center face vertical plane by 30 mm toward the heel portion, the heel side vertical plane extending from adjacent the crown portion to adjacent the sole portion and intersecting with the striking face surface to define a heel side roll contour;
a center face horizontal plane passing through the center face location, the center face horizontal plane extending from adjacent the toe portion to adjacent the heel portion and intersecting with the striking face surface to define a center face bulge contour;
a crown side horizontal plane being spaced away from the center face horizontal plane by 15 mm toward the crown portion, the crown side horizontal plane extending from adjacent the toe portion to adjacent the heel portion and intersecting with the striking face surface to define a crown side bulge contour;
a sole side horizontal plane being spaced away from the center face horizontal plane by 15 mm toward the sole portion, the sole side horizontal plane extending from adjacent the toe portion to adjacent the heel portion and intersecting with the striking face surface to define a sole side bulge contour;
wherein the toe side roll contour is more lofted than the center face roll contour, the heel side roll contour is less lofted than the center face roll contour, the crown side bulge contour is more open than the center face bulge contour, and the sole side bulge contour is more closed than the center face bulge contour.

2. The golf club of claim 1 , wherein a point located at 20 mm above the center face location has a FA°Δ of between 0.1° and 4° relative to the center face location, and wherein a critical point located at 15 mm above the center face location has a LA°Δ that is substantially unchanged compared to a 0° twist golf club head.

3. The golf club of claim 1 , wherein a point located at 20 mm above the center face location has a FA°Δ of between 0.3° and 3° relative to the center face location.

4. The golf club of claim 1 , wherein a point located at 20 mm below the center face location has a FA°Δ of between −0.1° and −4° relative to the center face location.

5. The golf club of claim 1 , wherein a point located at 20 mm below the center face location has a FA°Δ of between −0.3° and −3° relative to the center face location.

6. The golf club of claim 1 , wherein an average FA°Δ of an upper toe quadrant is between 0.3° to 0.5°.

7. The golf club of claim 1 , wherein a heel side point located at a x-y coordinate of (30 mm, 0 mm) has a LA°Δ relative to the center face location that is between 0° and −8°, and wherein a toe side point located at a x-y coordinate of (−30 mm, 0 mm) has a LA°Δ relative to the center face location that is between 0° and 8°.

8. The golf club of claim 1 , wherein an average LA°Δ of an upper toe quadrant is between 0.4° to 0.8°.

9. The golf club of claim 1 , wherein the striking face has a variable face thickness having an inverted recess in a center portion of a back surface of the striking face.

10. A golf club head comprising:
a hosel portion, a heel portion, a sole portion, a toe portion, a crown portion, and a striking face having a striking face surface;
a fastener opening configured to allow the insertion of a fastening member in order to attach and detach the golf club head relative to a shaft;
a sleeve portion connected to the shaft portion, the sleeve portion being capable of adjusting the loft, lie, or face angle of the club head when the sleeve portion is removed from the hosel portion in a first configuration and reinserted into the hosel portion in a second configuration;
the striking face having a center face location;
a center face vertical plane passing through the center face location, the center face vertical plane extending from adjacent the crown portion to adjacent the sole portion and intersecting with the striking face surface to define a center face roll contour;
a toe side vertical plane being spaced away from the center face vertical plane by 30 mm toward the toe portion, the toe side vertical plane extending from adjacent the crown portion to adjacent the sole portion and intersecting with the striking face surface to define a toe side roll contour;
a heel side vertical plane being spaced away from the center face vertical plane by 30 mm toward the heel portion, the heel side vertical plane extending from adjacent the crown portion to adjacent the sole portion and intersecting with the striking face surface to define a heel side roll contour;
a center face horizontal plane passing through the center face location, the center face horizontal plane extending from adjacent the toe portion to adjacent the heel portion and intersecting with the striking face surface to define a center face bulge contour;
a crown side horizontal plane being spaced away from the center face horizontal plane by 15 mm toward the crown portion, the crown side horizontal plane extending from adjacent the toe portion to adjacent the heel portion and intersecting with the striking face surface to define a crown side bulge contour;
a sole side horizontal plane being spaced away from the center face horizontal plane by 15 mm toward the sole portion, the sole side horizontal plane extending from adjacent the toe portion to adjacent the heel portion and intersecting with the striking face surface to define a sole side bulge contour;
wherein the toe side roll contour is more lofted than the center face roll contour, the heel side roll contour is less lofted than the center face roll contour, the crown side bulge contour is more open than the center face bulge contour, and the sole side bulge contour is more closed than the center face bulge contour, wherein an average LA°Δ of an upper toe quadrant is between 0.4° to 0.8°.

11. A golf club head comprising:
a hosel portion, a heel portion, a sole portion, a toe portion, a crown portion, and a striking face having a striking face surface;
a sleeve portion connected to the shaft portion, the sleeve portion being capable of adjusting the loft, lie, or face angle of the club head when the sleeve portion is removed from the hosel portion in a first configuration and reinserted into the hosel portion in a second configuration; the striking face having a center face location; a center face vertical plane passi
