US Patent 9694259 Putter-type golf club head

A putter-type golf club head that, when oriented in a reference position, includes a striking wall extending in the heel to toe direction and defines a substantially planar striking surface for hitting a golf ball. A central elongate member is in communication with, and extends rearward from, the striking wall. An upper surface of the central elongate member includes a plurality of alignment elements. At least one of the plurality of alignment elements has a parallel visual indicator section, at least a portion of which extends substantially parallel to the striking surface. The width of the at least one of the plurality of alignment elements is substantially equivalent to the diameter of a golf ball.
