Abstract

The present invention has a body with front and back surfaces, top and bottom sides, and two opposed ends. A display panel is on the front of the body. A processor is housed within the body. A dial can be connected to the front end of the body. The dial can have a head with an opening therein for allowing a laser beam to be projected from the head. A grid can be on the head for manually determining the angle between the longitudinal axis of the body and the head. The processor can electronically determine the angle between the longitudinal axis of the body and the head. The head can project forward from the front surface of the body. A side of the body can abut the side of a piece of material to be cut. A laser line can then be projected onto the material surface.

Claims

1. A laser tool comprising:

a body having a first end and a second end, a longitudinal axis, a front surface between said first end and said second end and lying in a front surface plane, and a back surface opposed to said front surface, said front surface defining a front surface area;

a dial having a housing connected to said front surface of said body and operable within said front surface area, said housing having a laser beam selectably projected there from; and

a processor being in electrical communication with said dial, said processor being capable of determining a first angle between said laser beam and said longitudinal axis and determining a second angle between said longitudinal axis and level; and

a display for simultaneously displaying said first angle and said second angle.

2. The laser tool of claim 1 wherein said dial is rotatably connected to said front surface of said body.

3. The laser tool of claim 2 wherein said dial is rotatable 360 degrees with respect to said body.

4. The laser tool of claim 1 wherein said dial is at said first end of said body.

5. The laser tool of claim 1 wherein said display further comprises a level display and a set button, wherein said set button toggles between a plurality of preselected reference planes and wherein said level display displays the angle between said longitudinal axis and said selected reference plane.

6. The laser tool of claim 1 wherein said dial extends forward from said front surface, whereby said laser beam can mark a line across a front surface of an adjacent piece of material when a side of the adjacent piece of material contacts said body between said front surface and said back surface.

7. The laser tool of claim 1 wherein:

said processor selectably stores multiple angles, and is capable of later selectably displaying one or more of said stored multiple angles on said display.

8. A laser tool comprising:

a body having a front surface, a rear surface and a longitudinal axis, said front surface lying in a front surface plane;

a housing rotatably connected to said body and extending forward of said front surface of said body, said housing comprising an opening through which a laser beam is selectably projectable at a selected angle relative to said longitudinal axis and lying in a plane generally parallel to said front surface plane;

a processor in electrical communication with said housing, said processor being capable of measuring the angle between said laser beam and said longitudinal axis, and storing a selected number of measurements; and

a display for selectably displaying the measurements stored by the processor, wherein said display has a laser display for displaying the angle between said laser beam and said longitudinal axis as determined by said processor and said display has a level display for displaying the anile between said longitudinal axis and a determined reference plane as determined by said processor.

9. The laser tool of claim 8 wherein:

said front surface defines a front surface area; and

said housing comprises a dial that is operable in said front surface area.

10. The laser tool of claim 8 wherein said housing is rotatable 360 degrees.

11. The laser tool of claim 8 wherein said body has a first end and an opposed second end, and said housing is at said first end of said body.

12. The laser tool of claim 11 wherein said laser tool has a length of approximately 2 feet between said first end and said second end and said front surface has a height of approximately 2.5 inches, and said housing is generally circular shaped with a diameter of approximately 2 inches.

13. The laser tool of claim 8 wherein said laser beam can mark a line across a front surface of an adjacent piece of material when a side of the adjacent piece of material contacts said body between said front surface and said back surface.
