发明名称 Golf Club Head Or Other Ball Striking Device Having Impact-Influencing Body Features
摘要 A ball striking device has a face with a striking surface and a body extending rearwardly from the outer periphery of the face. A channel extends across at least a portion of the sole, and includes a trough defined between front and rear edges and extending in a heel-toe direction. The body further includes a spacing portion that forms a generally flattened surface extending from the front edge to proximate the outer periphery of the face. The rear edge of the channel is spaced rearwardly a different distance from the outer periphery of the face at the center portion of the channel as compared to the heel portion and/or the toe portion. One or more stiffening ribs may also be provided rearwardly of the channel, to increase the stiffness of the sole.
