    Abstract: A putter-type golf club head that, when oriented in a reference position, includes a blade portion having a striking face, a top line, and a sole, the striking face in turn including a face center. The club head further includes a rear portion in communication with, and rearward of, the blade portion, and it includes an alignment element rearward of, and recessed toward the sole from, the top line. The alignment element defines a virtual center line segment oriented in a substantially front-to-rear direction at a height between 19 mm and 24 mm from a lowermost point of the sole, the center line segment having a length no less than 34 mm and being not spaced more than 10 mm from a virtual vertical plane passing through the face center and extending generally perpendicular to the striking face. A width of the club head is no less than 3.0 in.

    IPC: A63B53/04

    Abstract: 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 face 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 separate alignment elements. At least one of the plurality of alignment elements has an edge that extends substantially parallel to the striking face. The length of the parallel edge is substantially equivalent to the diameter of a golf ball.

    Abstract: 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.
