METAL WOOD CLUB
A wood-type golf club including a head comprising a body having a face, a sole, a crown, a toe and a heel and a coordinate system with an x-axis extending horizontally tangent to a center of the club face, a y-axis extending vertically from the center of the club face, and a z-axis extending horizontally through the center of the club face. A system is disposed within the body for adjusting club face angle at address comprising an element that is rotatable about a system axis that is substantially parallel to the y-axis to provide at least first and second club face angle positions at address. The element may be any shape which changes club face angle at address. The system axis may alternatively be substantially parallel to the z-axis. Or, the element may even comprise a plurality of interchangeable adjustment portions interchangeably mated with a body portion.
1 . A wood-type golf club head comprising:
a body having a face, a sole, a crown, a toe and a heel;
the body having a coordinate system with an x-axis extending horizontally tangent to a center of the club face, a y-axis extending vertically from the center of the club face, and a z-axis extending horizontally through the center of the club face;
a system disposed within the body for adjusting club face angle at address comprising an element that is rotatable about a system axis that is substantially parallel to the y-axis to provide at least first and second club face angle positions at address.
2 . The wood-type golf club head of claim 1 , wherein the element interacts with the ground plane at address to change/modify the club face angle.
3 . The wood-type golf club head of claim 1 , wherein the system changes the golf club angle by less than 1°.
4 . The wood-type golf club head of claim 1 , wherein the system changes the golf club angle by at least about 1°.
5 . The wood-type golf club head of claim 1 , wherein the system changes the golf club angle by at least about 2°.
6 . The wood-type golf club head of claim 1 , the system changes the golf club angle by at least about 3°.
7 . The wood-type golf club head of claim 1 , wherein the system changes the golf club angle by greater than about 3°.
8 . The wood-type golf club head of claim 1 , wherein the element has a cylindrically shaped base member that is flush with the sole and a protrusion formed on and protruding from the base member for changing the club face angle at address.
9 . The wood-type golf club head of claim 1 , wherein the element is disc-shaped.
10 . The wood-type golf club head of claim 1 , wherein the element is wedge-shaped.
11 . The wood-type golf club head of claim 1 , wherein the element is tapered.
12 . The wood-type golf club head of claim 8 , wherein the protrusion interacts with the ground at address changing club face angle.
13 . The wood-type golf club head of claim 1 , wherein the system is disposed within the body between the toe and the heel at a distance from the heel that is greater than or substantially similar to a distance from the toe.
14 . The wood-type golf club head of claim 1 , wherein the body comprises a more than one system for changing club face angle at address spaced between the heel and the toe.
15 . The wood-type golf club head of claim 14 , wherein at least one of systems may be disengaged.
16 . The wood-type golf club head of claim 1 , wherein the system is secured within the body with at least one of mechanical locking means, welding means, brazing, or an adhesive.
17 . The wood-type golf club head of claim 1 , wherein the system comprises a material selected from the group comprising plastic, composite, or metal.
18 . A wood-type golf club head comprising:
a body having a face, a sole, a crown, a toe and a heel;
the body having a coordinate system with an x-axis extending horizontally tangent to a center of the club face, a y-axis extending vertically from the center of the club face, and a z-axis extending horizontally through the center of the club face;
a system disposed within the body for adjusting club face angle at address comprising an element that is rotatable about a system axis that is substantially parallel to the z-axis to provide at least first and second club face angle positions at address.
19 . The wood-type golf club head of claim 18 , wherein the system is disposed within the body between the toe and the heel at a distance from the heel that is less than a distance from the toe.
20 . A wood-type golf club head comprising:
a body having a face, a sole, a crown, a toe and a heel;
the body having a coordinate system with an x-axis extending horizontally tangent to a center of the club face, a y-axis extending vertically from the center of the club face, and a z-axis extending horizontally through the center of the club face; and
wherein the body comprises a weight member that is adjustable in a vertical direction to move the center of gravity in the vertical direction and is rotatable about a system axis that is substantially parallel to the y-axis to adjust club face angle at address.
21 . A wood-type golf club head comprising:
a body having a face, a sole, a crown, a toe and a heel;
the sole being disposed between the toe and the heel and comprising a body portion and one of a plurality of interchangeable adjustment portions;
wherein the body portion is integral with the body and the one of the plurality of interchangeable adjustment portions is interchangeably mated with the body portion;
such that for a club face angle X at address at location L, each of the plurality of interchangeable adjustment parts adjusts the club face angle X to a different club face angle X n wherein n is the number of interchangeable adjustment portions.
