Golf swing improvement device
First Claim
1. A Golf Swing Improvement Device for use on a golf club having a shaft, a handle at one end of said shaft, and a head at an opposite end of said shaft, said device comprising:
- a pair of semi-cylindrical members each having a planar surface, a convex surface, a semi-circular top surface, and a semi-circular bottom surface, said planar surface having a semi-circular groove therein extending from said semi-circular top surface to said semi-circular bottom surface, said semi-circular groove having a pair of axially aligned cavities therein;
a fastening means for mateably joining said pair of semi-cylindrical members to form a cylindrical sleeve member having a top surface and a bottom surface, and having a circular bore therethrough extending from said top surface to said bottom surface, said circular bore adapted to receive said shaft of said golf club, whereby said cylindrical sleeve member is slidably mounted on said shaft of said golf club; and
a concentric shaft contact means provided within said circular bore of said cylindrical sleeve member for concentrically contacting and hugging said shaft of said golf club, whereby said cylindrical sleeve member is free to slidably travel concentrically along said shaft between said handle and said head of said golf club during a swing thereof,wherein said concentric shaft contact means comprises a ball bearing protruding from each of said pair of axially aligned cavities into said circular bore of said cylindrical sleeve member, and a projection spring located within each of said pair of axially aligned cavities and positioned behind said ball bearing whereby said projection spring maintains said ball bearing in continuous contact with said shaft of said golf club as said cylindrical sleeve member slidably travels concentrically therealong.

Abstract
A new Golf Swing Improvement Device for helping a golfer determine the impact point of his or her golf swing. The inventive device includes a cylindrical sleeve member having a circular bore therethrough adapted to receive a shaft of a golf club, and a Plurality of spring-biased shaft contact members provided within the circular bore for contacting and hugging the shaft of the golf club, whereby the cylindrical sleeve member is free to slidably travel along the length of the shaft of the golf club during a swing thereof. The shaft contact members compensate for the taper in the shaft of the golf club and allow the cylindrical sleeve member to slidably travel concentrically along the shaft of the golf club between the handle and the head.
