Abstract

See full text

A golf putter head of triangular shape. A ball-striking leading wall has a first breadth greater than a second breadth of a trailing wall. The leading and trailing walls are interconnected at their respective opposite ends by sidewalls that converge toward one another and define a cavity of trapezoidal shape. The center of gravity of the golf putter head is closer to the trailing wall than the leading wall to provide a moment of inertia that reduces the effects of missing a sweet spot on the leading wall during a putt. In one embodiment, the trailing wall is weighted to move the center of gravity closer to the trailing wall. In another embodiment, a web interconnects the leading and trailing walls along a longitudinal axis of the golf putter head. Another embodiment adds a pair of weights to the leading end of each sidewall, significantly increasing the moment of inertia.
