Patent ID: 7269907

Claim:
A laser alignment device disposable on a reference surface, comprising: a laser generating device including a housing and a laser generator, the laser generator arranged to produce a fan shaped beam of light defining a plane; and a base having bottom surface adapted for placement parallel to the reference surface, the base including an upper attachment portion arranged to receive a bottom portion of the housing and a lower attachment portion pivotally connected to the upper attachment portion, the lower attachment portion comprising; an indicator ring having one or more tabs extending from a bottom surface thereof; an indexing ring; and a base portion that receives the one or more tabs thereby securing the indicator ring to the base portion with the indexing ring held between the indicator ring and the base portion such that the indicator ring is rotatable relative to the base portion, wherein the housing and the base are coupled to one another to permit the fan shaped beam of light to propagate in a direction parallel to the plane of the bottom surface such that the plane of the fan shaped beam of light is arranged to extend perpendicular relative to the reference surface when the bottom surface is disposed adjacent the reference surface thereby creating a line of light on the reference surface.
