Abstract

The present invention relates to laser guided tractor trailer docking apparatuses and methods of making and using the same. Specifically, apparatuses are provided for projecting a laser line emanating from a tractor trailer loading dock to guide a tractor trailer driver backing the tractor trailer into proper position at the loading dock.

Claims

1. A laser line system comprising:

a loading dock comprising a vertical surface disposed adjacent a horizontal surface upon which a truck traverses to load and unload goods at the loading dock;

a first laser line generating apparatus situated immediately adjacent the vertical surface of the loading dock, the first laser line generating apparatus projecting a first line on both the vertical surface of the loading dock and the horizontal surface, the first line emanating both down the vertical surface of the loading dock and away from the loading dock on the horizontal surface to aid a truck driver in safely docking the truck to the loading dock.

2. The laser line system of claim 1 wherein the first laser line generating apparatus is situated above the loading dock.

3. The laser line system of claim 1 wherein the first laser line generating apparatus comprises a plurality of laser line generators aligned in parallel, wherein the plurality of laser line generators work in concert together to broaden the first line projected from the first line generating apparatus.

4. The laser line system of claim 1 further comprising a second laser line generating apparatus situated in proximity to the loading dock and a length away from the first laser line generating apparatus, the second laser line generating apparatus projecting a second line on at least the surface and emanating away from the loading dock to aid the truck driver in docking the truck to the loading dock, wherein the second line is parallel with the first line.

5. The laser line system of claim 4 wherein the length the second laser line generating apparatus is away from the first laser line generating apparatus is greater than a width of the truck.

6. The laser line system of claim 4 wherein the second laser line generating apparatus comprises a plurality of laser line generators aligned in parallel, wherein the plurality of laser line generators work in concert together to broaden the second line projected from the second line generating apparatus.

7. The laser line system of claim 4 wherein the second laser line generating apparatus further projects the second line on the vertical surface.

8. The laser line system of claim 1 wherein the laser line generating apparatus comprises:

a first laser generator and a first lens capable of expanding a laser beam dot to form a first projected laser line, the first lens being disposed in front of the first laser generator; and

a second laser generator and a second lens capable of expanding a laser beam dot to form a second projected laser line, the second lens being disposed in front of the second laser generator;

wherein the first laser generator and the second laser generator are aligned such that the first projected laser line is projected adjacent the second projected laser line.

9. The laser line system of claim 8 wherein the laser line generating apparatus further comprises:

a third laser generator and a third lens capable of expanding a laser beam dot to form a third projected laser line, the third lens being disposed in front of the third laser generator;

wherein the third laser generator is aligned with the first laser generator and the second laser generator such that the third projected laser line is projected adjacent the first projected laser line and the second projected laser line.

10. The laser line system of claim 8 wherein the first projected line and the second projected line are projected along the vertical surface.

11. The laser line system of claim 8 wherein the first projected line and the second projected line are projected along the horizontal surface.

12. A method of using a laser line for docking a truck, the method comprising the steps of:

providing a loading dock comprising a vertical surface disposed adjacent a horizontal surface upon which a truck traverses to load and unload goods at the loading dock;

providing a first laser line generating apparatus, the first laser line generating apparatus capable of projecting a first line; and

situating the first laser line generating apparatus immediately adjacent the vertical surface of the loading dock;

projecting a first laser line on both the vertical surface of the loading dock and the horizontal surface, the first line emanating both down the vertical surface of the loading dock and away from the loading dock on the horizontal surface to aid a truck driver in safely docking the truck to the loading dock.

13. The method of claim 12 further comprising the steps of:

providing a second laser line generating apparatus, the second laser line generating apparatus configured to project a second laser line;

situating the second laser line generating apparatus in proximity to the loading dock and a length away from the first laser line generating apparatus; and

projecting the second laser line on the horizontal surface, the second line emanating away from the loading dock to aid a truck driver in docking a truck to the loading dock.

14. The method of claim 12 wherein the first laser line generating apparatus is situated above the loading dock.

15. The method of claim 13 wherein the second laser line generating apparatus is situated above the loading dock, further comprising the steps of:

projecting the second laser line on the vertical surface.
