摘要:
Putters include a putter body having a ball striking face member (204) made of a material having a first hardness characteristic. Independent and separate openings (206) are defined in the ball striking face member extending rearward with respect to the ball striking face member and at a non-perpendicular angle with respect to the ball striking surface. Optionally a cavity (208) is present behind the ball strikign surface. A polymeric material at least partially fills the openings and the cavity, wherein the polymeric material has a second hardness characteristic that is softer than the first hardness characteristic. The ball striking face member and the polymeric material exposed in at least some of the openings provide a ball striking surface of the putter. The ball striking surface may include grooves or scorelines to affect the launch angle, spin, and/or roll of the ball during a putt. Methods for making such putter devices also are described.
摘要:
Ball striking devices, such as golf club heads (including putter heads), have a high moment of inertia about their center, to help prevent twisting and mis-hits, particularly when the ball striking device hits the ball at a somewhat off center position. The ball striking head of the ball striking device may be structured and/or weighted (optionally with separately attachable weight elements) to have a moment of inertia about a center of the ball striking surface of at least 10,000 g/cm 2 , and in some examples, the moment of inertia may be at least 11,000 g/cm 2 , or even at least 12,000 g/cm 2 . In some examples, the moment of inertia may be at least 20,000 g/cm 2 , or even at least 25,000 g/cm 2 or at least 28,000 g/cm 2
