Luminous golf practice device
First Claim
1. An auxiliary luminous device, for assisting a user with golfing practice, comprising a light beam transmitter and an optical unit arranged to diffuse a generated light beam in a plane;
- the device being used in combination with a golf club having a striking surface;
the transmitter and the optical unit being attached to the golf club;
the optical unit being aligned relative to the golf club so that the plane in which the light beam is to be diffused extends perpendicular to the striking surface of the golf club and passes through a point of impact between a golf ball, to be struck by the golf club, and the striking surface, and the light beam, when diffused, forms a line of light on the ground during a golfing stroke; and
the optical unit being located behind a plane defined by the striking surface.

Abstract
A device designed to be fitted to or built into a golf club such as a putter to assist in learning the correct club position, in particular for indoor or home putting practice. A transmitter unit is releasably attached to the shaft of the club and comprises a laser diode for transmitting a parallel light beam towards an optical unit having a cylindrical lens above the club iron. The lens diffuses the light along a vertical plane to form a beam directed at the ground in front of the iron, whereby the player is able to see a line of light on the ball and on the ground indicating the direction in which the ball will travel depending on the position of the striking surface of the iron. In one embodiment, the optical system may be supported by an arm attached to the shaft.

10. A method of using an auxiliary luminous device, comprising a light beam transmitter and an optical unit arranged to diffuse a generated light beam in a plane, to assist a user with golfing practice, the method comprising the steps of:
-
using the device in combination with a golf club having a striking surface; attaching the transmitter and the optical unit to the golf club; aligning the optical unit relative to the golf club so that the plane in which the generated light beam is to be diffused extends perpendicular to the striking surface of the golf club and forms a line of light on the ground during a golfing stroke; and locating the optical unit behind a plane defined by the striking surface so that the plane in which the generated light beam is diffused passes through a point of impact between a golf ball, to be struck by the golf club, and the striking surface.
