Abstract

A device for insuring that directional stability is monitored and maintained in three axes when addressing a golf ball with a golf club. Visual alignment and club head positioning is obtained through the use of holograms affixed to the heads of the clubs so that a visual check by the holder of the club reveals the image or object in three dimensions when the dub is improperly positioned and in two dimensions when it is perfectly positioned. Image color(s) are also used to enhance recognition of proper club head positioning.

Claims

1. A device comprising a three-dimensional hologram affixed to a golf club to enable precise golf club positioning relative to three axes of rotation when preparing to hit a golf ball to a specific target on a preselected trajectory, wherein said hologram combines vertical, horizontal and planar rotation imaging which enables club head positioning through visual observation of a three-dimensional rhombohedron image, said hologram being affixed to an upper surface of a head of said golf club in a manner such that said three-dimensional image appears within a reference perimeter on a background field in a configuration that indicates proper golf club head positioning for a shot having a particular desired target and trajectory, and wherein indications of golf club positioning are combined in a single hologram directly visible to a golfer when addressing a golf ball.

2. The device according to claim 1, wherein violation of said reference perimeter indicates mispositioning of said golf club relative to two specified axes of rotation.

3. The device according to claim 1, wherein colored sides on said rhombohedron indicate golf club mispositioning through two specified axes of rotation.

4. The device according to claim 1, wherein planar rotation imaging on a top surface of said rhombohedron shows disjointed lines when said golf club is mispositioned relative to one specified axis of rotation.

5. The device according to claim 1, wherein the hologram is made of photopolymer plastic.

6. The device according to claim 1, wherein the hologram is made of polyester.

7. The device according to claim 1, wherein the hologram is made of hot stamping foil.

8. The device according to claim 1, wherein the hologram has a self-adhesive backing.

9. The device according to claim 1, wherein the hologram has a water-activated adhesive backing.

10. The device according to claim 1, wherein said golf club is a wood-type golf club comprising a club head, and said affixed hologram has as a background a field upon which the reference perimeter and the rhombohedron in contrasting colors are placed providing coloring for said wood-type golf club head.
