Groove influence for golf irons and drivers
Abstract
Grooves made for irons and drivers of golf clubs are adjusted so
they will give a desirable rotation for the golf ball after impact.
Beside the other possible adjustments that I mention, the grooves
will primarily have one wall slanted to the other wall. This will
allow the ball to release in a direction and or intensity level
different than the standard grooves. In the United States Golf
Association the golf irons and drivers have different rules and
regulations than golf putters.

Claims
1. I claim that this invention will influence the rotation of the
golf ball when struck by a golf iron or golf driver.
Description
BACKGROUND OF THE INVENTION
[0001] The grooves in golf clubs are usually embedded into the face
of the clubs straight in with the walls and the edges of the groove
identical. The grooves of the club helps grip the golf ball on
impact, which gives influence on how the ball will rotate in the
air and the intensity of rotation. My invention will allow the ball
rotate in a more favorable and a more predictable way. With the
invention I kept in mind the rules and regulations of the United
States Golf Association. Putters do have different rules and
regulations.
BRIEF SUMMARY OF THE INVENTION
[0002] The invention primarily is to change the angle of the walls
of the grooves. It may require changing only one wall angle or both
wall angles depending on the intensity level wanted. The invention
will also adjust if needed the radius of the edges of the groove
points (where the clubface and the walls of the groove come
together). This will offer adjusted resistance to influence the
golf ball's rotation and intensity rotation in a more desired
manner after the golf ball releases from the clubface at
impact.
BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS
[0003] FIG. 1
[0004] This is a partial side view of the clubface and how the
grooves are indented into the face of the club. For this example
the walls of the grooves A-side is on top and B-side is on the
bottom. "C" labels the flat part of the clubface.
[0005] FIG. 2
[0006] This is a partial side view of the face of the clubface with
the B-Side wall of the groove of the club angled towards the A-Side
wall. For this picture A-Side of the club is on top and B-side is
bottom. A-Side and B-Side can be flipped.
[0007] FIG. 3
[0008] This is a partial side view of the face of the club with
B-Side on top of A-Side. Changing A-Side and B-Side will reverse
the influence.
[0009] FIG. 4
[0010] This picture is a partial side view of the groove. In this
drawing you see the rounding edge and wall that would be on B-Side
designated by a dashed line. The rounding radius ("D") would have
been set at the range from the largest as allowed by the USGA to
the same size A-Side's rounded edge ("E"). A point from the
beginning to the end of the possible rounding ("G" to "H") is where
the sloped edge would begin and go to A-Side's point "F".
[0011] FIG. 5
[0012] This is partial side view that shows how the groove of the
invention would look.
DETAILED DESCRIPTION OF THE INVENTION
[0013] The invention is to change the angle of the grooves in the
face of the golf clubs of irons and drivers. This will allow the
golf ball to rotate after impact in a favorable rotation direction
or intensity. The standard grooves of the golf club are usually as
similar to each other as possible. There will be two sides of the
groove referred to as A-Side and B-Side. This invention will adjust
the angle of one wall (B-Side) to reduce the resistance and the
other wall (A-Side) will be at 90 degrees (or less) to offer more
resistance. If the A-Side were less the wall would have an angle
that would slope away from the B-Side. The B-Side will have an
angle that will slope towards A-Side. This will influence the
ball's rotation and intensity of the rotation.
[0014] This invention will also utilize the rounding of the edges
where the groove walls meet the face of the club. The groove edges
will be at least equal to each other (A-Side edge rounding =B-Side
edge rounding). If not the A-side will have a smaller radius of
rounding edge than B-Side. A-Side will have as small as a radius as
possible and the B-Side will have a Radius as Large as possible.
The starting point of the slope from B-Side to A-Side will be in
between the beginning and the end of the rounding edge on the
B-side. The end of the slope will be at the bottom of the A-Sides
wall. The clubface will still have space in between each
groove.
[0015] The less steep of an angle from one wall of the groove
(B-Side) to another (A-Side) will offer less resistance of the golf
ball to release from the club. The larger length of the A-Side wall
will offers more resistance of the golf ball to release from the
club. If A-Side wall is angled less than 90 degrees (away from
B-Side) this will offer more resistance. The smaller of radius of
the rounding on A-Side or B-side of the edges will offer more
resistance. These factors being adjusted will influence the ball to
release and rotate towards the less resistance side (B-Side) or the
golf ball will release and rotate with not as much intensity of the
more resistance side (the A-Side). (A-Side and B-Side can be
rotated (flipped). They can be switched to get a different rotation
or intensity of rotation. When describing the invention I kept in
mind of USGA's rules and regulations.
