The centerline of the head is a line drawn from the center of gravity to a perpendicular line that is on the flat surface of the head face or a perpendicular line that is tangent to a curved concaved or convex surface, and is parallel to the ground, and is at the same height as the center of gravity of the head. This invention consists of a grip and shaft centerline that is attach to the head so that this centerline will intersect the centerline of head. The sweet spot is where the centerline of the head will pierce the face plane of the head. This club head includes a highlighted straight line above and parallel to the center-line of the club head. This acts as a sight line to assist the golfer to align the club head to the center of the golf ball, and align the sight line to a imaginary line that goes from the center of the golf ball to its target. The center of gravity location can be changed by changing the weight and weight location of the club head mass or by changing the hole size or hole location.
The present golf club assembly has a club head with no fore and aft holes protruding through the head. This club head during a forward swing mode has a lot of air resistance to the face of the club head, which causes a reduced speed of the head and causes the ball to travel a shorter distance to its target. This same golf club head does not have a concave surface at the hill of the head that produces a partial vacuum at a center hole that allows the air flow through the hole to move the ball to the sweet spot of the head. The center-line of the grip and shaft is located off center to the sweet spot and center-line of the head, and has a offset of 1.5-2.0 inches. During a forward swing mode the air resistance will produce a torsional deflection about the centerline of the shaft and the face of the head will rotate and cause the ball to travel to the left or right of its target (depending on a L. H. or a R. H. Golfer). When the club head makes contact with the golf ball and this offset (1.5 to 2.0 inches) produces a torque about the center line of the grip and shaft. This torque is great enough to cause the club head face to rotate about the center line of to grip and shaft, causing the golf ball trajectory to be right or left of its target. The same is true when a right or left hand golfer produces a divot. When the centroid of the divot is off center to the center line of the grip and shaft, it also produces a torque about the center line of the grip and shaft. The summation of all torques are great enough to cause the club head face to rotate about the center line of the grip and shaft, which causes the golf ball trajectory to be right or left of its target, depending on a right or left hand golfer.
A “Aerodynamic Golf Club Assembly” consisting of a golf shaft and grip which is attached to the golf club head. The club head has one or more holes that protrude from the face of the head to the hill of the head. The hill of the head has a concave surface, so a stronger vacuum is created during a forward swing mode of the club head. This partial vacuum at the center hole will suck more air from the front face of the head and suck the ball to the sweet spot of the head. The centerline of the center hole is on center with the centerline of the club head. This allows the golfer to swing the club head at a higher speed (mph), because it has less air resistance at the face of the head.
The center line of the grip and shaft is attached to the club head so that its center-line will intersect the centerline of the club head. The centerline of the head is a line drawn from the center of gravity to a perpendicular line that is on the flat surface of the head or a perpendicular line that is tangent to a curved concaved or convex surface, and is parallel to the ground, and is at the same height as the center of gravity of the head. The sweet spot on the club head face is where the center-line of the club head will pierce the club head face surface. This club head includes a highlighted straight line above and parallel to the center-line of the club head. This acts as a sight line to assist the golfer to align the club head with the center of the golf ball, and align it with a imaginary line that is going from the center of the golf ball to its target. The lie of the golf club is of any angle to the ground line. The centerline of the shaft is of any angle to the center-line of the head in the top and end view. The loft of the golf club is of any angle to the ground line. The claims for this invention are for any size golf club and is made of any type of material.
A “Aerodynamic Golf Club Assembly” has four views shown as follows:
Referring now to the drawings where in the presently preferred embodiment of this invention is illustrated.
Any golfer can use a “Aerodynamic Golf Club Assembly” at any time or any place. The Golfer must align the sweet spot of the head with the center of the ball, and align the sight line of the club head, so as to coincide with a imaginary line that is drawn from the center of the ball to its target. He then should re-grip the club shaft after this adjustment and keep the desired club head position that was set for the club head intact. He is now ready to drive the ball to its target. When the sweet spot of the club head contacts the ball, it will drive the ball further and with more accuracy to its target, because it has no moment of inertia that is creating a torque about the center-line of the shaft. The center hole in the head is on the same center line as the centerline of the head, and will suck the ball to its sweet spot with every forward stroke and will reduce the air resistance at the face of the club head, and giving the ball more distance of travel.
