Golf club with plural alternative impact surfaces
First Claim
1. A golf club having an elongated shaft and a head having a central axis fixed to the shaft so that the central axis extends at an obtuse angle to said shaft, the head comprising an adjustable section which is a square with four planar faces in a plane normal to the central axis rotatably connected and supported about the central axis, the adjustable section being rotatably positionable at any one of four orientations relative to the shaft, the orientations constituting rotational positions of the adjustable section about the central axis so that in each position at least one of the planar faces is disposed in a ball-impacting position relative to the shaft, each planar face having a different rebound factor when impacting a ball.

Abstract
A golf club having a shaft and an elongated head projecting at a lie angle relative to the shaft, the head having the shape of a regular polygon in a cross section at right angles to the central axis of the head, with each face being formed of a material that provides a different ball rebound factor, the head section being rotatable about the central axis so that any one of the faces may be presented for use with the club.

- 1. A golf club having an elongated shaft and a head having a central axis fixed to the shaft so that the central axis extends at an obtuse angle to said shaft, the head comprising an adjustable section which is a square with four planar faces in a plane normal to the central axis rotatably connected and supported about the central axis, the adjustable section being rotatably positionable at any one of four orientations relative to the shaft, the orientations constituting rotational positions of the adjustable section about the central axis so that in each position at least one of the planar faces is disposed in a ball-impacting position relative to the shaft, each planar face having a different rebound factor when impacting a ball.

3. A golf putter having an elongated shaft and a head connected to one end of the shaft with a central axis extending at an angle to the shaft, said head comprising:
-
a first section fixed relative to the shaft; and a second section, rotatably connected and supported relative to the first section, which is square with four planar faces in cross section in a plane normal to the central axis of the head to form a plurality of substantially planar ball-impacting faces each parallel to the central axis, each face being formed of a material providing a different rebound factor when impacting with a golf ball, relative to the other faces, the section being positional in any one of a plurality of rotational orientations relative to the shaft, and each orientation providing at least one face substantially parallel to a plane passing through the shaft and the central axis of the neck to present a ball-impacting face having a rebound factor dependent on the chosen rotational orientation.

4. A golf putter head comprising:
-
an elongated neck adapted to receive a shaft; a head connected to the neck having a central axis projecting at an angle relative to the shaft; the head having a section fixed relative to the shaft and an adjustable section being rotatably connected and supported relative to the fixed section and selectively positionable at any one of a plurality of orientations constituting rotational positions of the sections about the central axis so that in each position at least one of the planar faces is disposed substantially parallel to a plane through the length of the shaft and the central axis to form a ball-impacting surface,each planar face having a different rebound factor when impacting a ball. - View Dependent Claims (5, 6)

7. A golf putter comprising:
-
an elongated shaft; a heel section fixed to one end of the shaft; and a blade portion, elongated about a central axis, adapted to be rotatably connected and supported relative to the heel so the central axis extends at an obtuse angle to the shaft, the blade portion being square in cross section normal to the central axis with four faces, each parallel to the central axis, each face providing a different impact factor with respect to a golf ball, and a separable connector adapted to allow a first end of the blade to be rotated about the heel section to one of a plurality of rotational positions of the blade relative to the central axis, so as to position any one of the faces in a ball-impacting position. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)

16. A golf putter club comprising:
- an elongated shaft, a grip formed on one end of the shaft, a head formed at the other end of the shaft having a central axis projecting at a lie angle relative to the shaft, the head having a section with a regular polygonal cross section in a plane normal to the central axis, forming a plurality of substantially parallel faces, the section being rotatably connected and supported relative to the balance of the head and selectively positionable at any one of a plurality of orientations constituting rotational positions of the section about the central axis so that in each position at least one of said planar faces is disposed in a ball-impacting position, each planar face having a different rebound factor when impacting a ball.

17. A golf putter club comprising:
-
an elongated shaft; a heel section fixed to one end of the shaft; a blade portion, elongated about a central axis, rotatably connected to the heel so the central axis extends at an obtuse angle to the shaft, the blade portion being square in cross section normal to the central axis with four faces, each parallel to the central axis, each face providing a different impact factor with respect to a golf ball, and a connector rotatably joining the blade portion to the heel section, adapted to allow a first end of the blade to be rotated about the heel section to one of a plurality of rotational positions of the blade relative to the central axis, so as to position any one of the faces in a ball-impacting position; and a toe portion, rotationally attached to a second end of the blade so that the orientation of the toe portion remains constant with the orientation of the heel section after rotation of the blade portion.
