发明名称 High moment of inertia putter
摘要 A golf putter head has a generally triangular shape where a ball-striking leading wall has a first breadth greater than a second breadth of a trailing wall. The leading wall and trailing wall are interconnected at their respective opposite ends by sidewalls that converge toward one another and define a cavity having a trapezoidal shape. The center of gravity of the golf putter head is closer to the trailing wall than the leading wall so that a moment of inertia is generated that reduces the effects of missing a sweet spot on the leading wall during a putt. In a second embodiment, the trailing wall is weighted to move the center of gravity still closer to the trailing wall. In a third embodiment, a web interconnects the leading and trailing walls along a longitudinal axis of the golf putter head, dividing the cavity into two equal-sized cavities.
