Patent ID: 7031367

Claim:
A laser level disposable on a first reference surface comprising: a housing; a pendulum pivotably connected to the housing; a lock mechanism for fixing the position of the pendulum relative to the housing, wherein said lock mechanism comprises a pivotable lock movable between a first position contacting the pendulum and a second position bypassing the pendulum; a first laser diode disposed on the pendulum for emitting a first laser beam along a first path; a first lens disposed on the pendulum in the first path for converting the first laser beam into a first planar beam, the first planar beam forming a first line on the first reference surface; a second laser diode disposed on the pendulum for emitting a second laser beam along a second path; and a second lens disposed on the pendulum in the second path for converting the second laser beam into a second planar beam, the second planar beam forming a second line on the first reference surface, wherein the first and second lines are substantially perpendicular and non-intersecting.
