Abstract

A laser leveling device having a suction mounting arrangement includes a housing and a mounting seal extending from the lower portion of the housing. The mounting seal cooperates with an attachment surface to define a suction mounting area therebetween. The suction mounting arrangement cooperates with the mounting seal to maintain the vacuum pressure seal in the suction mounting area. A laser light source mounted within the housing in a planar relationship relative to the attachment surface includes at least one diode projecting an alignment beam through an opening in the housing to denote a reference plane along the attachment surface.

Claims (13)

1. A laser leveling device comprising:

a. a housing;

b. a mounting seal extending from a lower portion of the housing and cooperating with an attachment surface to define a suction mounting area therebetween;

c. a suction mounting arrangement cooperating with the mounting seal to maintain the suction mounting area, wherein the suction mounting arrangement includes a vacuum generating mechanism including a pump configured to remove air from the suction mounting area through an aperture in the cavity to secure the housing to the attachment surface; and,

d. a laser light source disposed within the housing, the laser light source including at least one diode projecting an alignment beam to denote a reference plane along the attachment surface, wherein the alignment beam is selectively rotatable with respect to the suction mounting area.

2. The laser leveling device of claim 1 wherein the alignment beam is projected on the attachment surface at a selected angle between 0° and 360°.

3. The laser leveling device of claim 1 wherein the alignment beam is projected onto one of the attachment surface, an adjacent surface, or both.

4. The laser leveling device of claim 1 wherein the alignment beam is projected onto one of a first surface adjacent to the attachment surface, a second surface adjacent to the attachment surface, or both, wherein the first and second surfaces are different.

5. The laser leveling device of claim 1 further comprising a switch extending through the housing allowing a user to activate the laser light source when the laser level is positioned on the attachment surface.

6. The laser leveling device of claim 1 wherein the pump is a manually operable pump.

7. The laser leveling device of claim 6 further comprising a switch located externally of the housing to actuate the pump.

8. The laser leveling device of claim 1 wherein the vacuum generating mechanism further includes a motor to drive the pump.

9. The laser leveling device of claim 1 further comprising a switch located externally of the housing to actuate the pump.
