Abstract

The laser-based alignment device includes a housing and at least two laser devices affixed to the housing. Each of the at least two laser devices emits a laser beam. At least one alignment mechanism is positioned on the housing and is engagable to a structure, wherein the laser beam is positioned at a predetermined angle to the structure when the at least one alignment mechanism is attached to the structure.

Claims (5)

1. A laser-based alignment device comprising: a housing configured with a first surface oriented substantially parallel to a second surface and substantially perpendicular to a third surface and to a fourth surface, the third surface being a top surface and the forth surface being a bottom surface; two laser devices affixed to the housing and configured to emit at least one laser beam perpendicular to said first surface from each of the two laser devices; a first and a second alignment mechanism positioned on said third surface said first alignment mechanism adapted to engage an L-shaped component of a suspended ceiling system; a second alignment mechanism adapted to engage a T-shaped support component of a suspended ceiling system; an alignment structure positioned on said first surface aligned in the plane of the fourth surface and adapted to engage a wall surface to provide an offset between said first surface and said wall surface substantially equal to the width of said L-shaped component, said at least one laser beam from each laser device being positioned at a 90 degree angle to said L-shaped component when said first alignment mechanism is engaged with said L-shaped component; said at least one laser beam from each laser device being positioned at a 90 degree angle to said T-shaped component when said second alignment mechanism is engaged with said T-shaped component, wherein a biased retaining device positioned within said second alignment mechanism is adapted to engage a groove if present in said T-shaped component, and wherein a laser marking is created by said at least one laser beam from each laser device on a surface positioned proximate thereto, the laser marking on the surface having at least one of a parallel orientation, a perpendicular orientation, and a level orientation with respect to said L-shaped component or said T-shaped component.

2. The laser-based alignment device of claim 1 , wherein a first laser device of the two laser devices is positioned to emit one laser beam along a first plane, and a second laser device of the two laser devices is positioned to emit one laser beam along a second plane, and the first plane is perpendicular to and intersects the second plane.

3. The laser-based alignment device of claim 1 , said alignment structure further comprising an elongated wall abutment edge positioned parallel to said first surface and within the plane of the fourth surface, wherein the wall abutment edge is sized to engage with a wall by flushly contacting the wall.

4. The laser-based alignment device of claim 3 , wherein when said housing is placed on a floor and the wall abutment edge is flushly contacting the wall surface, at least one of the laser beams creates a laser marking on said floor.

5. A method of using a laser-based alignment device, the method comprising the steps of: providing the laser-based alignment device including two laser devices, two alignment mechanisms, and an alignment structure affixed to a housing, wherein at least one laser beam is emitted from each of the at least two laser devices perpendicular to a first surface on said housing; engaging said alignment structure to a wall surface; engaging a first alignment mechanism to an L-shaped component of a suspended ceiling system, said component being mounted on said wall surface; positioning said first alignment mechanism on the housing to align said first surface with said wall surface, thereby orienting the at least one laser beam emitted from each said laser device at a 90 degree angle with respect to said L-shaped component, one laser beam being emitted along a first plane, and the other laser beam being emitted along a second plane, where the first plane is perpendicular to and intersects the second plane.
