Abstract: The present invention is directed to a novel golf putter having a novel head, which is made up of a strike plate, a body, and at least one connecting element. The connecting element is positioned with a spacing element so that the strike plate does not make direct contact with the body when the putter is used to strike a golf ball. As such, during the striking of the golf ball with the strike plate of the novel putter, kinetic energy is transferred from the strike plate to the body via the connecting element and the spacing element, and the energy is transferred in a direction perpendicular or substantially perpendicular to the plane of the face of the strike plate.

Abstract: A golf club head has a face, a hosel, and a hollow body. The body includes an outer peripheral region, when viewed from above, and center portions on the upper surface and sole, respectively. The outer peripheral region has a weight-per-unit of surface area which is greater than the weight-per-unit of surface area of the center portions. The weight differential may be accomplished by molding ports into the hollow body around the periphery, which contain weight plugs. Alternately or in addition, a vertically oriented port may extend through the center portions to reduce weight.

Abstract: This utility model refers to a golf putter that, contrary to a head with a straight and plain face, has a circular, plain, vertical, smooth and graded face. With a common putter, a player aligns himself with the line of putt. However, with the use of a circular and plain face, a player aligns himself with the hole. The putter's head indicates the line of putt. This being, a player's stroke is always perpendicular to the ball's axis and in direction of the line of putt's angle. With a circular and plain face, the head is positioned and, thus, the angle is no longer 0°. Rather, it takes on a specific degree reflecting the chosen line of putt. The angle only changes through repositioning the putter. This utility model is applicable in the manufacturing of Putters.

A proper setup is attained by a golfer when the shaft is seen by the golfer as substantially parallel to at least one of the alignment markings.

Abstract: A golf putter has a putter head with an actively compliant beam which is parallel to the face of the putter. The beam connects to a shaft along its length and is separated from the head except for its ends. The force of impact between the face of the putter and the ball on the putter face sweet spot causes a stress to develop in the beam, resulting in a deflection in the beam proportional to the force of the impact, while maintaining the putter face orientation with respect to the putting line. Impacts which miss the sweet spot will cause the putter face to skew to an angle with respect to the putting line, also introducing a proportional flexure of the beam, depending on the distance between the sweet spot and the point of impact.
