Abstract

A putter-type golf club head is disclosed. When oriented in a reference position, the putter-type golf club head comprises a blade member and a central elongate member in communication with, and extending rearwardly from, the blade member. The blade member extends in a heel-to-toe direction and has a striking wall defining a substantially planar striking surface, and an upper surface of the central elongate member comprises at least one generally square-shaped alignment element.

First claim

What is claimed is:

1. A putter-type golf club head that, when oriented in a reference position, comprises:
a blade member extending in a heel-to-toe direction and having a striking wall defining a substantially planar striking surface; and
a central elongate member in communication with, and extending rearwardly from, the blade member, wherein:
an upper surface of the central elongate member comprises at least one generally square-shaped alignment element,
the width in the heel-to-toe direction of the upper surface of the central elongate member is greater than the width in the heel-to-toe direction of a bottom surface of the central elongate member,
the upper surface and the bottom surface of the central elongate member are connected by at least one sidewall, and
the at least one sidewall tapers toward a longitudinal vertical center plane of the central elongate member from the upper surface to the bottom surface.

2. The putter-type golf club head of claim 1 , wherein:
the blade member comprises a front portion proximate to the striking wall and a rear portion extending rearwardly from the front portion; and
an upper surface of the front portion is above an upper surface of the rear portion.

3. The putter-type golf club head of claim 2 , wherein the upper surface of the rear portion of the blade member is overlapped by the upper surface of the central elongate member.

4. The putter-type golf club head of claim 3 , wherein the upper surface of the front portion of the blade member is coplanar with the upper surface of the central elongate member.

5. The putter-type golf club head of claim 1 , further comprising a substantially T-shaped body.

6. The putter-type golf club head of claim 1 , wherein:
the width of the central elongate member in the heel-to-toe direction is greater than the diameter of a golf ball; and
the width of the at least one alignment element in the heel-to-toe direction is slightly less than the diameter of the golf ball.

7. The putter-type golf club head of claim 1 , wherein the club head is face-balanced.

8. A putter-type golf club head that, when oriented in a reference position, comprises:
a blade member extending in a heel-to-toe direction and having a striking wall defining a substantially planar striking surface; and
a central elongate member in communication with, and extending rearwardly from, the blade member, wherein:
an upper surface of the central elongate member comprises a first alignment element and a second alignment element, each having a visual indicator portion extending parallel to the striking face and a width in the heel-to-toe direction corresponding to the diameter of a golf ball,
the second alignment element is rearwardly spaced from the first alignment element,
the width in the heel-to-toe direction of the upper surface of the central elongate member is greater than the width in the heel-to-toe direction of a bottom surface of the central elongate member,
the upper surface and the bottom surface of the central elongate member are connected by at least one sidewall, and
the at least one sidewall tapers toward a longitudinal vertical center plane of the central elongate member from the upper surface to the bottom surface.

9. The putter-type golf club head of claim 8 , wherein the blade member comprises a front portion proximate to the striking wall and a rear portion extending rearwardly from the front portion; and
an upper surface of the front portion is above an upper surface of the rear portion.

10. The putter-type golf club head of claim 9 , wherein the upper surface of the rear portion of the blade member is overlapped by the upper surface of the central elongate member.

11. The putter-type golf club head of claim 10 , wherein the upper surface of the front portion of the blade member is coplanar with the upper surface of the central elongate member.

12. The putter-type golf club head of claim 8 , further comprising a substantially T-shaped body.

13. The putter-type golf club head of claim 8 , wherein:
the width of the central elongate member in the heel-to-toe direction is greater than the diameter of a golf ball; and
the widths of the first and second alignment elements in the heel-to-toe direction are slightly less than the diameter of the golf ball.

14. The putter-type golf club head of claim 8 , wherein the club head is face-balanced.

15. A face-balanced putter-type golf club head that, when oriented in a reference position, comprises:
a generally rectangular blade member extending in a heel-to-toe direction and comprising:
a striking wall defining a substantially planar striking surface;
a front portion proximate to the striking wall; and
a rear portion extending rearwardly from the front portion, an upper surface of the front portion being above an upper surface of the rear portion; and
a central elongate member that is in communication with, and that extends rearwardly from, the blade member and that has a width in the heel-to-toe direction greater than the diameter of a golf ball, the central elongate member comprising:
an upper surface (1) overlapping the upper surface of the rear portion of the blade member and (2) being coplanar with the upper surface of the front portion of the blade member;
a bottom surface, the width in the heel-to-toe direction of the upper surface of the central elongate member being greater than the width of the bottom surface; and
at least one sidewall that connects the upper surface and the bottom surface of the central elongate member, the at least one sidewall tapering toward a longitudinal vertical center plane of the central elongate member from the upper surface to the bottom surface, wherein:
the upper surface of the central elongate member comprises a first alignment element and a second alignment element each having substantially the same generally square shape;
the second alignment element is rearwardly spaced from the first alignment element;
forward indicators of the first and second alignment elements are substantially parallel to the striking surface;
centers of the first and second alignment elements are intersected by an imaginary vertical plane that (1) is perpendicular to the striking surface, and (2) intersects a center of the striking wall in the heel-to-toe direction; and
widths of the first and second alignment elements in the heel-to-toe direction correspond to the diameter of the golf ball.
