Pendulum putting system
Pendulum putting system including a golf putter with a shaft gripping portion, a shaft, and a center shafted putter head. The shaft is attached to the putter head so that the resulting angle between the ground plane of the putter head and the shaft length is greater than seventy two degrees. The shaft is less than thirty-two inches in length and the putter head weighs more than four hundred grams. A preferred embodiment includes a system where the user grips the gripping portion in a symmetrical fashion consisting of the palmer surfaces of the two index fingers to be extended along the length of the grip, the remaining fingers interlocked and the thumbs overlapped with gripping pressure being applied to the the putter grip by the palms, interlocking fingers, extended index fingers and overlapping thumbs.

BACKGROUND OF THE INVENTIONThis invention relates generally to the field of golf clubs and more specifically to a pendulum putting system.
The game of golf has been in existence for hundreds of years. There is a long history of efforts to improve golf club construction in order to reduce the number of strokes needed to knock the golf ball into the hole. One of the most challenging aspects of the game of golf is the short game where the golfer must use a putting club to direct the ball accurately, a short distance to the hole.
One recommended method of swinging a putter club effectively is a pendulum action where the user holds the grip portion of the shaft and the grip portion is held as a fulcrum point and the club head swings to hit the ball toward the hole. A number of inventors have designed putter type clubs that are meant to improve a pendulum type swing. For example, Mr. Kropp, in his U.S. Pat. No. 3,574,349 discloses a pendulum style putter where the user holds the putter to one side of his body and holds onto the top of the grip portion with one hand which forms the fulcrum point of the swing. U.S. Pat. No. 5,700,206 by Lin shows a pendulum putter that is used croquet style. The Vaughn pendulum putter, U.S. Pat. No. 6,394,011 shows a pendulum putter that uses a T handle grip as a fulcrum point for the swing. Both the Zichmanis U.S. Pat. No. 6,783,463 and the Moore U.S. Pat. No. 6,213,891 disclose a grip style where the hands of the golfer hold the club in a symmetrical fashion.
While all the above listed patents attempt to improve a golfers putting game, they do not address a number of crucial issues. First, most of the existing putters have a long shaft that forces the golfer to stand erect during the putt while holding his elbows close to his trunk. This creates tension in the arms and shoulders, which is not helpful to the putting motion. Additionally, as the golfer rotates his or her shoulders in an upright stance, the path of the putter is in the shape of an arc with a relatively small radius, with the face of the putter opening and closing during the putt. This makes it difficult to strike the ball with a square putter face. Some instructors, to insure a square club head face at impact, teach golfers to keep the club head on a straight line during the putt. The problem with this approach is that it requires the golfer to use his arm and shoulder muscles to move the hands and club in an unnatural motion, resulting is further tension in the arms and shoulders that impede a pure pendulum motion. In addition, the conventional right hand low grip impedes motion in the back swing, forcing the golfer to swing the putter in an unsymmetrical motion, with less range of motion in the back swing and a larger range of motion in the follow through. Lastly, the light weight of most putter heads forces the golfer to use muscular effort to hit the ball, rather than relying on the weight of the putter as would happen with a purely pendulum motion.
BRIEF SUMMARY OF THE INVENTIONThe primary object of the invention is to provide a putting system that improves the user's pendulum type putting stroke.
Another object of the invention is to provide a golf putting club that reduces arm and shoulder tension therefore improving putting motion.
Another object of the invention is to provide a golf putting club that allows the user to maintain a wider, more stable stance.
A further object of the invention is to provide a golf putting club that provides a heavier club head for a more natural pendulum action.
Yet another object of the invention is to provide a golf putting club that includes a shorter than normal shaft length to let the user's arms hang straight down and still maintain the center of the putter directly below his eyes at address and at impact.
Still yet another object of the invention is to provide a golf putting club that allows the user to grip the gripping portion in a symmetrical fashion with index fingers placed along the sides of the lower length of the putter grip.
Other objects and advantages of the present invention will become apparent from the following descriptions, taken in connection with the accompanying drawings, wherein, by way of illustration and example, an embodiment of the present invention is disclosed.
In accordance with a preferred embodiment of the invention, there is disclosed a pendulum putting system comprising: a shaft gripping portion, a shaft, and a center shafted putter head; said shaft attached to said putter head so that the resulting angle between the ground plane of said putter head and said shaft length is greater than seventy two degrees; said shaft being less than thirty-two inches in length, and said putter head weighing more than four hundred grams.

Claims
1. pendulum putting system comprising:
- a shaft gripping portion;
- a shaft; and
- a center shafted putter head.
- said shaft attached to said putter head so that the resulting angle between the ground plane of said putter head and said shaft length is greater than seventy two degrees;
- said shaft being less than thirty-two inches in length;
- and said putter head weighing more than four hundred grams.
2. pendulum putting system as claimed in claim 1 wherein a user grips the gripping portion in a symmetrical fashion consisting of the palmer surfaces of the two index fingers to be extended along the length of the grip, the remaining fingers interlocked and the thumbs overlapped, and the end of the putter grip fitting in the depression between the two pads on the palm of each hand, with gripping pressure being applied to the said putter grip by the palms, interlocking fingers, extended index fingers and overlapping thumbs.
