Intersecting Laser Line Generating Device
First Claim
Patent Images
1. A laser beam generating device comprising:
- a housing having a base, the base defining a base plane;
a laser light generator mounted within the housing;
a lens mounted in the housing, the lens receiving laser light from the laser light generator and projecting a first beam of laser light outside the housing;
a cutout portion of the housing defined by a volume of space between an area defined by a perpendicular projection of a perimeter of the housing onto the base plane and the housing;
wherein at least a portion of the first beam is projected through the cutout portion and onto a working surface adjacent the base, the at least a portion of the first beam remaining within the cutout portion from the point where the first beam exits the housing until the first beam intersects the base plane.

Abstract
A line generating device generates two fan-shaped beams of light at an angle to each other, and projects the beams onto an adjacent surface, where the beams are visible as lines on the surface. A user has access to the intersection of the lines, so that the intersection can be marked or otherwise used in combination with the lines, such as in aligning objects.

15. A laser beam generating device comprising:
-
a housing having a base, the base defining a base plane;
a laser light generator mounted within the housing, the laser light generator projecting a first beam of laser light; and
a first beam exit disposed in the housing, the beam exit being spaced apart from and facing the base plane;
wherein the first beam is projected through the first exit and onto a substantially horizontal surface within the base plane, the first beam being projected from above the surface and normal to the surface. - View Dependent Claims (16, 17, 18, 19, 20)
