Abstract
A golf putter having a shaft and a putting head connected to the shaft, where the putting head has a first contact surface, a rear wall, a top surface, and a sole. The first contact surface has a concave, partially-spherical face. In a version of the invention, the first contact surface has a first concave, cylindrical face instead of the partially-spherical face. Some versions have a second contact surface opposite the first contact surface. The first contact surface and the second contact surface may have a partially-spherical face, a cylindrical face, or a combination of the two faces. In embodiments with two contact surfaces, the shaft is configured to be reversible such that either contact surface can be used.
Claims16
A golf putter comprising a shaft and a putting head connected to the shaft, the putting head comprising:
- (a) a first contact surface, wherein the first contact surface is partially-spherical and further comprises
- a first radius,
- wherein the radius of the partially-spherical face is greater than the measurement of a golf ball radius,
- a first perimeter edge,
- a second perimeter edge,
- a first apex, and
- a first depth, wherein the first depth is defined as a distance between the first apex and a first plane defined by the first perimeter edge and the second perimeter edge, and
- wherein the first depth is between about 0.84 inch and about 1.68 inches;
- (b) a rear wall, the rear wall being opposite the first contact surface;
- (c) a top surface, the shaft being connected to the putting head at the top surface, the top surface being connected to the first contact surface and to the rear wall;
- and
- (d) a sole, wherein the sole is opposite the top surface and connected to the first contact surface and the rear wall;
- (e) wherein the distance between the top surface and the sole is at least one-half the radius of a golf ball.
