Abstract

A laser alignment device includes a laser generating device, an upper attachment portion, and a lower attachment portion. The laser generating device includes a housing and a laser generator. The upper attachment portion is disposed near a bottom of the housing, and the lower attachment portion is pivotally and/or rotationally connected to the upper attachment portion.

Claims

1. A laser alignment device, comprising:

a laser generating device including a housing and a laser generator;

an upper attachment portion disposed near a bottom of the housing; and

a lower attachment portion pivotally connected to the upper attachment portion.

2. The laser alignment device of claim 1, wherein the upper attachment portion is removably attached to the housing.

3. The laser alignment device of claim 1, wherein the upper attachment portion is integral to the housing.

4. The laser alignment device of claim 1, wherein the lower attachment portion is slideably connected to the upper attachment via a joining portion.

5. The laser alignment device of claim 4, wherein the upper attachment portion is disposed between a retainer of the joining portion and the lower attachment portion.

6. The laser alignment device of claim 4, wherein the retainer is attached to the lower attachment portion via one of a screw and a bolt.

7. The laser alignment device of claim 4, wherein the retainer includes a convex bottom surface that corresponds and slidingly engages with the concave upper attachment portion.

8. The laser alignment device of claim 1, wherein the upper attachment portion includes a convex bottom surface that corresponds and slidingly engages with a concave recess disposed in the lower attachment portion.

9. The laser alignment device of claim 1, wherein the lower attachment portion is rotatably connected to the upper attachment portion.

10. The laser alignment device of claim 1, further including an adhesive strip attached to a bottom of the lower attachment portion, wherein the adhesive strip is adapted to temporarily attach the laser alignment device to a working surface.

11. The laser alignment device of claim 10, wherein the laser alignment device, once attached to the working surface, may be removed from the working surface by pulling on a portion of the adhesive strip extending beyond the lower attachment portion.

12. The laser alignment device of claim 11, wherein the portion of the adhesive strip extending beyond the lower attachment portion is pulled in a direction generally parallel to the working surface.

13. A laser alignment device, comprising:

a laser generating device including a housing and a laser generator; and

an attachment portion having an upper surface and a lower surface, wherein the attachment portion is rotateably connected to the laser generating device at the upper surface and wherein the lower surface is adapted to be removably connected to a working surface.

14. The laser alignment device of claim 13, wherein the attachment portion has one of a generally round and oval shape.

15. The laser alignment device of claim 13, wherein the attachment portion includes a plurality of markings radially disposed around a periphery of the attachment portion.

16. The laser alignment device of claim 15, wherein the plurality of markings are equally and angularly spaced apart from each other.

17. A laser alignment device, comprising:

a laser generating device including a housing and a laser generator;

an upper attachment portion disposed near a bottom of the housing; and

a lower attachment portion rotatably connected to the upper attachment portion.

18. The laser alignment device of claim 17, wherein the upper attachment portion is removably attached to the housing.

19. The laser alignment device of claim 17, wherein the upper attachment portion is integral to the housing.

20. The laser alignment device of claim 17, wherein the lower attachment portion is slideably connected to the upper attachment via a joining portion.

21. The laser alignment device of claim 20, wherein the upper attachment portion is disposed between a retainer of the joining portion and the lower attachment portion.

22. The laser alignment device of claim 20, wherein the retainer is attached to the lower attachment portion via one of a screw and a bolt.

23. The laser alignment device of claim 20, wherein the retainer includes a bottom surface that corresponds and slidingly engages with the upper attachment portion.

24. The laser alignment device of claim 17, wherein the upper attachment portion includes a bottom surface that corresponds and slidingly engages with a concave recess disposed in the lower attachment portion.

25. The laser alignment device of claim 17, wherein the lower attachment portion is pivotally connected to the upper attachment portion.

26. The laser alignment device of claim 17, further including an adhesive strip attached to a bottom of the lower attachment portion, wherein the adhesive strip is adapted to temporarily attach the laser alignment device to a working surface.

27. The laser alignment device of claim 26, wherein the laser alignment device, once attached to the working surface, may be removed from the working surface by pulling on a portion of the adhesive strip extending beyond the lower attachment portion.

28. The laser alignment device of claim 27, wherein the portion of the adhesive strip extending beyond the lower attachment portion is pulled in a direction generally parallel to the working surface.

29. The laser alignment device of claim 17, wherein the attachment portion includes a plurality of markings angularly disposed around a periphery of the lower attachment portion.

30. The laser alignment device of claim 29, wherein the plurality of markings are equally spaced apart from each other.

31. A laser alignment device, comprising:

a laser generating device including a housing and a laser generator adapted to generate a laser light;

an upper attachment portion disposed near a bottom of the housing; and

a lower attachment portion rotatably connected to the upper attachment portion, wherein the lower attachment portion includes a plurality of index markings around a periphery thereof for corresponding the laser light to a rotational position.

32. The laser alignment device of claim 31, wherein the plurality of index markings include numerical markings of forty-five degrees and ninety degrees.

33. The laser alignment device of claim 31, wherein the plurality of index markings include tick marks at least every five degrees.

34. The laser alignment device of claim 31, further including an indexing ring rotatably attached to and disposed around a periphery of the lower attachment portion wherein the indexing ring includes the plurality of index markings.

35. The laser alignment device of claim 31, further including an indicator arm attached to the lower attachment portion and radially aligned with the laser light thereby indicating the rotational position of the laser light.

36. The laser alignment device of claim 35, wherein the indicator arm is rotatably attached to the lower attachment portion.

37. The laser alignment device of claim 31, further including an adhesive strip attached to a bottom of the lower attachment portion, wherein the adhesive strip is adapted to temporarily attach the laser alignment device to a working surface.
