Golf putting club

Abstract

The present invention generally comprises a golf putter having a putting surface with a negative loft angle of about -10.degree. to -2.degree.. The putter surface strikes the ball at approximately the center of gravity of the club and above the vertical centerline of the ball, imparting overspin and eliminating the tendency for the ball to skid, bump or become airborne. The negative loft angle is such that the putter face contacts the ball above the centerline with each stroke, imparting topspin on the ball 100% of the time, independent of variable putting conditions. An alternate preferred embodiment of the present invention combines the negative loft putting face with a convex putting surface as circumscribed by arc of radius at least 5 inches and at most 84 inches. This convex putting surface is designed to minimize the trajectory errors caused by planar face putters by producing a ball trajectory which in most cases reduces the misalignment created by a nonzero contact angle between the ball and the putter face. In other words, if the angle of contact with putter face of the present invention is misaligned by 1 degree from that which would produce a straight line trajectory to the hole, the ball will travel a path that is less than or equal to 1 degree to the right or left of the hole, thus producing a more accurate alignment with the hole.
