GOLF CLUB HEAD

摘要

A golf club head has a striking face with a plurality of scorelines including a first scoreline and a second scoreline adjacent thereto. The striking face also has a plurality of auxiliary grooves each spaced from the scorelines. In a first imaginary vertical plane, a first path is formed by a first intersection between the first imaginary vertical plane and the striking face, and the auxiliary grooves have a first concentration no less than 0.17 measured between the first and second scorelines. A second imaginary vertical plane is horizontally spaced from the first imaginary plane. A second path is formed in the second imaginary vertical plane by a second intersection between the second imaginary vertical plane and the striking face. The auxiliary grooves in the second imaginary vertical plane have a second concentration that is different from the first concentration measured between the first and second scorelines.

主权项

1. A golf club head that when oriented in a reference position relative to a ground plane comprises:
a heel portion and a toe portion opposite the heel portion; a hosel extending from the heel portion; and a striking face having
a striking face plane generally coplanar with the striking face; anda plurality of scorelines including at least a first scoreline and a second scoreline adjacent the first scoreline, wherein:
one or more first auxiliary grooves are interspersed between, and entirely spaced from, the plurality of scorelines, and follow an inclined path relative to the ground plane at an angle between 5 and 50 degrees relative to the horizontal, measured in the striking face plane; andone or more second auxiliary grooves are interspersed between, and entirely spaced from, the plurality of scorelines, and follow a declined path relative to the ground plane at an angle between 5 and 50 degrees relative to the horizontal, measured in the striking face plane.
