Laser golf alignment device and method
First Claim
1. A sport alignment device comprising:
- an elongated housing with a center region and two ends;
a first light source located in said housing'"'"'s center region;
second and third light sources located in said ends on swivel platforms;
a battery contained in said housing;
at least one control switch attached to said housing;
wherein said battery is electrically connected to said control switch and to said light sources, and wherein said control switch can activate or deactivate said light sources;
said device having two modes;
wherein, in a first mode, said device projects at least three light beams in a plane, a first beam in a direction of play, a second beam in a direction perpendicular to the first beam, and a third beam in a direction opposite to the direction of the second beam; and
wherein, in a second mode, said second and third light sources swivel approximately 90 degrees to project two parallel beams in said plane.

Abstract
A portable, expandable laser golf training device that can be placed on the ground to provide alignment. The present invention can supply a plurality of light beams produced by lasers or other light sources, switchable on and off, that can be projected along the ground both in the direction of play and perpendicular to it. In a folded configuration, the device can project in four directions creating a pair of axis lines running at right angles to each other. In an expanded configuration, one of the major axis lines can be separated into two parallel lines for putting alignment by sliding the halves of the device apart. The device can be used by placing it on the ground in front of the golfer (between the golfer'"'"'s feet and the ball. Two lines project outward perpendicular to the direction of play, and two or four lines project into and away from the direction of play. These lines provide alignment for the golfer. Various combinations of beams on or off can be selected by a selector switch under control of the user. The device can contain a rechargeable battery.

- 8. A golf alignment device comprising an elongated housing that has a center-mounted laser and two end-mounted lasers, the end-mounted lasers each being attached to rotatable and slideable end-platforms, wherein in a first mode, the device projects two beams of light outward from the ends of the elongated housing along a longitudinal axis of the elongated housing from said end-mounted lasers and a third beam of light outward from said center-mounted laser perpendicular to the two beams of light, and wherein, in a second mode, with said end-platforms rotated approximately 90 degrees, said end mounted lasers project two approximately parallel beams of light perpendicularly to said longitudinal axis, and wherein said end-platforms can be slide in the direction of said longitudinal axis toward or away from each other changing the separation between said to approximately parallel beams of light.
