Abstract

A laser leveler comprises a multiplicity of laser generators. One of the laser levelers is disposed in a top section which is rotatable with respect to a base section. The laser generator within the top section is rotatable through an angle of 90° between the horizontal and the vertical. A second laser generator is disposed within a midsection, located between the base and the top section. The laser generator within the midsection is capable of generating a vertical laser beam.

Claims

1. A laser leveler comprising:

(a) a base;

(b) a top section comprising at least one top section laser generators, the at least one laser generator being rotatable upwardly through an angle of about 90°

.

2. The laser leveler of claim 1 wherein the at least one laser generator is disposed within an arm which is pivotable through an arc of up to 45°

.

3. The laser leveler or claim 1 when the top section comprises three top section laser generators, each spaced apart from adjoining laser generators by about 120°

.

4. The laser leveler of claim 1 further comprising a midsection having a midsection laser generator, capable of generating a vertical laser beam when the laser leveler is disposed on a horizontal surface.

5. The laser leveler of claim 1 wherein the midsection is rotatable with respect to the base, either clockwise or counter-clockwise, through an angle of at least 180°

.

6. The laser leveler of claim 1 wherein the top section is rotatable with respect to the midsection, either clockwise or counter-clockwise, through an angle of at least 180°

.

7. The laser leveler of claim 1 further comprising a pair of level indicators, one of the level indicators being adapted to facilitate the leveling of the laser leveler when the laser leveler is disposed on a generally horizontal surface, and one of the level indicators being adapted to facilitate the leveling of the laser leveler when the laser leveler is disposed on a generally vertical surface.

8. The laser leveler of claim 1 wherein the base comprises at least three feet, at least one of the feet comprising an internally mounted needle slidably disposed within the foot and adapted to alternatively extend outwardly beyond the foot in an extended position or retract within the foot in a retracted position.

9. A laser leveler comprising a base having at least three feet, at least one of the feet comprising an internally mounted needle slidably disposed within the foot and adapted to alternatively extend outwardly beyond the foot in an extended position or retracted within the foot in a retracted position.
