Abstract

Aspects of the invention are directed to golf club having a crown a sole and a face and a primary alignment feature including a paint or masking line which delineates the transition between at least a first portion of the crown having an area of contrasting shade or color with the shade or color of the face. In some embodiments the golf club has a primary alignment feature comprising a paint or masking line which delineates the transition between at least a first portion of the crown having an area of contrasting shade or color and the area of shade or color of the face and the club head also includes a secondary alignment feature including a paint or masking line which delineates the transition between the first portion of the crown having an area of contrasting shade or color with the shade or color of the face; and a second portion of the crown having an area of contrasting shade or color with the shade or color of the first portion.

First claim

That which is claimed is:

1. A golf club head comprising:
a golf club body having a face, a crown and a sole together defining an interior cavity, the golf club body including a heel and a toe portion and having an x, y and z axes which are orthogonal to each other having their origin at USGA center face and
wherein the golf club head has a primary alignment feature comprising a paint or masking line which delineates a transition between at least a first portion of the crown having an area of contrasting shade or color with a shade or color of the face;
wherein the primary alignment feature has;
a. a Sight Adjusted Perceived Face Angle (SAPFA) of from about −2 to about 10 degrees; and
b. a Sight Adjusted Perceived Face Angle 25 mm Heelward (SAPFA25H) of from about −5 to about 2 degrees, and
c. a Sight Adjusted Perceived Face Angle 25 mm Toeward (SAPFA25T) of from 0 to about 9 degrees; and
d. a Sight Adjusted Perceived Face Angle 50 mm Toeward (SAPFA50T) of from about 2 to about 9 degrees, and
e. a Radius of Curvature (circle fit) of from about 300 to about 1000 mm.

2. The golf club head of claim 1 wherein:
a. the Sight Adjusted Perceived Face Angle (SAPFA) is from 0 to about 6 degrees; and
b. the Sight Adjusted Perceived Face Angle 25 mm Heelward (SAPFA25H) is from about −3 to 0 degrees, and
c. the Sight Adjusted Perceived Face Angle 25 mm Toeward (SAPFA25T) is from about 1 to about 4.5 degrees; and
d. the Sight Adjusted Perceived Face Angle 50 mm Toeward (“SAPFA50T”) is from about 3.5 to about 8 degrees, and
e. the Radius of Curvature (circle fit) is from about 400 to about 900 mm.

3. The golf club head of claim 1 wherein:
a. the Sight Adjusted Perceived Face Angle (SAPFA) is from about 0.5 to about 4 degrees; and
b. the Sight Adjusted Perceived Face Angle 25 mm Heelward (SAPFA25H) is from about −2 to about −1 degrees, and
c. the Sight Adjusted Perceived Face Angle 25 mm Toeward (SAPFA25T) is from about 2 to about 4 degrees; and
d. the Sight Adjusted Perceived Face Angle 50 mm Toeward (“SAPFA50T”) is from about 4 to about 7 degrees, and
e. the Radius of Curvature (circle fit) is from about 500 to about 775 mm and
f. the primary alignment feature has a ΔE*ab between the portion of the crown having an area of contrasting shade or color and the shade or color of the face is greater than 40.

4. The golf club head of claim 1 wherein the Sight Adjusted Perceived Face Angle (SAPFA) is from about 1 to about 2.5 degrees; and
wherein the primary alignment feature has a ΔE*ab between the portion of the crown having an area of contrasting shade or color and the shade or color of the face is greater than 60.

5. The golf club head of claim 4 wherein a color of the portion of the crown having an area of contrasting shade or color is white and the shade or color of the face is black.

6. A golf club head comprising:
a body having a face, a sole and a crown, the crown having a first portion having a first color or shade and a second portion having a second color or shade, the face, crown and sole together defining an interior cavity, the golf club body including a heel and a toe portion and having an x, y and z axis which are orthogonal to each other having their origin at USGA center face;
and
wherein the golf club head has a primary alignment feature comprising a paint or masking line which delineates a transition between at least a first portion of the crown having an area of contrasting shade or color with a shade or color of the face;
and
wherein the club head further comprises a secondary alignment feature comprising a paint or masking line which delineates the transition between the first portion of the crown and the second portion of the crown having an area of contrasting shade or color with the shade or color of the first portion of the crown;
wherein the secondary alignment feature comprises a first elongate side having a length of from about 0.5 inch to about 1.7 inches, and second and third elongate sides extending back from the face and rearward from and at an angle to the first elongate side.

7. A golf club head comprising:
a body having a face, a sole and a crown, the crown having a first portion having a first color or shade and a second portion having a second color or shade, the face, crown and sole together defining an interior cavity, the golf club body including a heel and a toe portion and having an x, y and z axis which are orthogonal to each other having their origin at USGA center face;
and
wherein the golf club head has a primary alignment feature comprising a paint or masking line which delineates a transition between at least a first portion of the crown having an area of contrasting shade or color with a shade or color of the face;
and
wherein the club head further comprises a secondary alignment feature comprising a paint or masking line which delineates the transition between the first portion of the crown and the second portion of the crown having an area of contrasting shade or color with the shade or color of the first portion of the crown;
wherein the secondary alignment feature has a Sight Adjusted Perceived Face Angle Secondary Alignment Feature, (“SAPFASAF”) of from about −2 to about 6 degrees.

8. The golf club head of claim 7 wherein the Sight Adjusted Perceived Face Angle Secondary Alignment Feature, (“SAPFASAF”) is from 0 to about 5 degrees.

9. The golf club head of claim 7 wherein:
a. the Sight Adjusted Perceived Face Angle Secondary Alignment Feature, (“SAPFASAF”) is from about 1.5 to about 4 degrees and
b. the secondary alignment feature has a ΔE*ab between the color or shade of the first portion of the crown and the second color or shade of the second portion of the crown is greater than 40.

10. The golf club head of claim 9 wherein the first portion of the crown is white and the second portion of the crown is black.

11. The golf club head of claim 9 wherein the face is black.
