ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to providing a golf club having a more balanced feel in the hands of the user and maintaining a more balance throughout the swing of the golf club.
The hands are the only sensory bond between the body, the club and the club contact with the ball while the sweet spot of the club face is the point of perfect dynamic impact in striking the ball. The sensory information in striking the ball travels through the club to the golfer.
A majority of golfers lack the skill and ability to consistently reproduce a swing that strikes the ball at the sweet spot. Further, each club has a different loft and accordingly, the initial impact with the ball will vary in elevation in accordance with the angle of the face of the respective club and therefore the location of the sweet spot. The vast majority of errant strikes are pinside or outside of the sweet spot center.
In order to minimize problems such as referred to above, this invention has been made
SUMMARY OF THE INVENTION
The golf club includes a shaft that at its juncture to the hosel is of a smaller diameter than the adjacent end of the hosel in a plane that is generally parallel to the ground when the club is being held in a position of use just as the head initially contacts the golf ball while a weight (toe bar) is mounted to the club head to give a better feel in use. The weight is located more closely adjacent to the toe end surface to have its center of mass located at an elevation just above the initial contact of the club head with the ball and on a line that passes through the top apex of a triangle having the one (top) apex at the point the shaft central axis intersects the shaft proximal end, a second apex at the intersection of the shaft central axis with the ground and a third apex at the intersection of a line perpendicular to the ground and tangential to the toe terminal edge surface horizontally most remote from the shaft axis. The weight bar is located on the side of the club face opposite the club face.
One of the objects of this invention is to provide new and novel means for maintaining the balance feel of a golf club throughout the swinging of the golf club to hit a golf ball. Another object of the invention is to provide new and novel golf club construction with a golf head having as wide a sweet spot as possible without disrupting, at any point during the swing, the balance and feel. Still another object this invention is to provide new and novel positioning of weight means on a golf club head for obtaining a wider sweet spot on the club head. An additional object of the invention is to provide a new and novel attachment of a golf club shaft to the club hosel.
In order to obtain the desired feel of a golf club, an important factor is the weight distribution when taking into consideration all elements involved in a golf swing which include the users hands, the shaft, hosel, the club head including the heel and sole and the golf ball. The desired relative placement of these elements and weight distribution of the elements of the club depend on the elevation of the sweet spot and size of the club face.
