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, wherein at least the upward facing surface portion of the crown has a chroma value of less than 10; 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.

17. 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; and a striking surface situated so as to define an interface with the crown, wherein a top surface of the striking surface adjacent the crown has a black surface treatment.

18. 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, wherein a secondary location situated on the crown has a reflected intensity of at least 20% of the highest reflected intensity within a distance of at least 20% of a crown effective length from the highest reflected intensity location, wherein a zone of crown intensity is defined from the crown effective length in a direction of 30 degrees and negative 30 degrees from the crown effective length.
