ABSTRACT:
BACKGROUND OF THE INVENTION
The investigation has convinced me that most bad putts are a result of off-center hits on the face of the putter, causing the putter face to torque or turn changing the intended line on which the ball was to roll.
Putter design has been very generic developing a very low center of gravity with most of its weight in the lower half of the putter head. By lofting the face of the putter, the force applied causes the ball to rise before it begins to roll. Hopping and bouncing can cause the ball to go off-line. Putter shafts are usually thinner and softer causing them to bend and then kick or snap, thereby varying the force applied to the ball. This can vary the length of the putt with no way of the person knowing why the putt was long or short.
SUMMARY OF THE INVENTION
The improved putter design of the invention has a rear mounted shaft which enters or attaches to the center of a generally triangular shaped head. There is a rectangular slot cut vertically through the head behind the putter face. The triangular shape and the slot tend to divide and spread the force through the head from the shaft into two locations on the putter face. Since the force is directed away from the center of the putter, the point of incidence (often known as the “sweet spot”) is expanded.
The improved design enlarges this point of incidence, minimizing the number of hits which might turn or torque the putter head slightly about the shaft, thus increasing the number of putts that will stay on the intended line.
Since the putter head of this invention is designed with most of its weight in the upper half of the head, the force applied to the ball is in a more horizontal direction, thus reducing the lift on the ball and causing the ball to roll forward sooner, allowing for a truer roll every time. Thus, this putter incorporates a solid brass head which is engineered with most of its weight in its upper half (e.g. above the bottom of the putter front face) to produce a high center of gravity, while conforming to USGA rules.
The rectangular vertically extending slot the putter head is centered behind the front face and is the same width as the diameter of the golf ball. The outside edge of the ball and the sides of the rectangular slot are picked up and integrated by the player's eye to create a line that is used to aim the ball to the hole. Aiming the ball in this way has been found to be easier than trying to create a perfect 90° angle off the putter face. Since the path to the hole is more easily seen, the player's putting accuracy is greatly improved with this design.
The shaft of this putter is extra stiff to reduce another variable that can affect accuracy, namely to eliminate any kick when the putter face engages the ball. It is believed that since putting involves considerable touch and feel, the more consistent the feedback to the player, the more the player can develop his/her touch and improve putting ability.
The design of the grip also is chosen to minimize another variable. Since a person's fingers are segmented at the joints, placing them on a rounded surface can vary their position circumferentially on that surface. The present grip surface is segmented, i.e., it has a generally square cross-section, allowing for a better fit in the hand with the grip corners being engaged with the finger joints, which leads to a more consistent position on that surface. Since placement of the hands on the grip is the contact point to the putter, hand placement consistency should improve accuracy.
