First Claim
Patent Images
1. A putter-type golf club head that, when oriented in a reference position, comprises:
- a striking wall extending in a heel-to-toe direction and comprising a striking surface including a face center;
a central elongate member in communication with, and extending rearwardly from, the striking wall, the central elongate member including a top wall and a sole wall defining at least one hollow region therebetween, the top wall having a minimum thickness less than or equal to 5 mm;
a width W no less than 3.8 in;
a length L such that L*W is greater than 14 in2;
a mass between 300 g and 400 g;
a volume no greater than 60 cc;
a moment of inertia about a vertical axis extending through a center of gravity of the golf club head greater than or equal to 3,500 g*cm2; and
a maximum height hmax no less than 0.80 in, whereinin a vertical cross-section that is perpendicular to the striking surface and horizontally spaced from the face center by no greater than 0.5 in;
the club head includes, specific to the vertical cross-section, a forwardmost point and a rearwardmost point opposite the forwardmost point; and
a first height h1 of no less than 0.75*hmax, the first height h1 measured at a first rearward distance d1 equal to 0.5*L, the first rearward distance measured from the forwardmost point.

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.

10. A putter-type golf club head having a heel and toe defining a heel-to-toe direction and that, when oriented in a reference position, comprises:
-
a volume no greater than 60 cc; a length L; a width W not less than L; a striking wall extending in the heel-to-toe direction and comprising a substantially planar striking surface including a face center; a central elongate member in communication with, and extending rearwardly from, the striking wall, the central elongate member including a top wall and a sole wall defining at least one hollow region therebetween; an upper surface of the central elongate member comprising a plurality of alignment elements each having a length and a width substantially equivalent to the diameter of a golf ball, each of the plurality of alignment elements comprising a geometric center intersected by an imaginary vertical plane extending perpendicular to the substantially planar striking surface; a moment of inertia about a vertical axis extending through a center of gravity of the golf club head greater than or equal to 3,500 g*cm2; and a maximum height hmax no less than 0.80 in, wherein in a vertical cross-section that is perpendicular to the striking surface and horizontally spaced from the face center by no greater than 0.5 in; the club head includes, specific to the vertical cross-section, a forwardmost point and a rearwardmost point opposite the forwardmost point; and a first height h1 of no less than 0.75*hmax, the first height h1 measured at a first rearward distance d1 equal to 0.5*L, the first rearward distance measured from the forwardmost point. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
