Patent Images
1. A golf club head, comprising:
- a crown having at least an upward facing surface portion provided with a diffused surface treatment as viewed from an address orientation, wherein the diffused surface treatment defines a highest reflected intensity location on the crown in response to illumination from a light source situated within a cone of angular radius of about 30 degrees above the crown, further wherein a secondary location situated on the crown at a distance of at least 20% of a crown effective length from the highest reflected intensity location has a reflected intensity of at least 25% of the highest reflected intensity; and
a striking surface situated so as to define an interface with the crown.

Abstract
Golf club heads include white diffusing top surfaces to aid in club head alignment. Wood type club heads also include a dark diffusing club face so that a crown/face border is emphasized. Scorelines in wood type clubs can be provided with an intermediate contrast surface, and can be displaced from club face center to accommodate player perception when confronted with a white diffusing crown. Putter heads can include dark diffusing alignment lines, and iron-type club heads can include white diffusing surfaces at a sole portion of a club face, at a top line, or a top portion of a club face.

19. A metal wood-type golf club head comprising:
a body comprising a face plate positioned at a forward portion of the golf club head, a sole positioned at a bottom portion of the golf club head, a crown positioned at a top portion of the golf club head and a skirt positioned around a periphery of the golf club head between the sole and the crown;
wherein the head has a golf club head origin positioned on the face plate at an approximate geometric center of the face plate, the head origin including an x-axis tangential to the face plate and generally parallel to the ground when the head is in an address position, a y-axis generally perpendicular to the x-axis and generally parallel to the ground when the head is in an address position, and a z-axis generally perpendicular to the x-axis and to the y-axis and generally perpendicular to the ground when the head is in an address position, wherein a positive x-axis extends toward a club head heel, a positive y-axis extends toward the cavity, and a positive z-axis extends away from the ground with the head in the address position, wherein at least a perimeter portion of the crown adjacent a top portion of the faceplate and having an area that is at least 5% of the crown area has a bright, diffusely reflecting surface, and at least a top perimeter portion of the face plate has a dark diffusely reflecting surface area.- View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
