Abstract

This invention is directed to a novel, portable, self-powered laser alignment device which can simultaneously generate plumb, square and level laser reference points. The laser alignment device is comprised of a main body that is pendulously suspended from a unit housing. The main body is adapted to house a plurality of orthogonally oriented laser diodes that, when energized, produce a plurality of orthogonal output beams to allow the operator to easily mark plumb, square and level reference points. The laser alignment device is self-leveling, which eliminates the time consuming calibration previously required for instrument setup. The movement of the main body is dampened by use of a magnetic dampening system that is comprised of a non-magnetic metallic plate, which is passed through a permanent magnetic field. The housing of the laser alignment device contains the main body, the laser diodes, the dampening system and a power supply to energize the diodes.

Description

technical field [0001] This invention relates to alignment devices used in the construction industry, and more particularly to a new, portable, self-powered laser alignment device capable of simultaneously producing vertical, square, and horizontal laser fiducials. Background technique [0002] Traditional instruments used to determine the reference point on site, such as 3-4-5 settable, plumb bob, bubble bottle level, optical theodolite, and alidade, are time-consuming and require at least two people to obtain the desired reference point position . These existing methods usually require specialized training to obtain accurate measurement results. A laser diode capable of producing a linear beam is mounted on a horizontal plane to generate horizontal lines for vertical or lateral measurements of objects or surfaces. These laser units can only produce a single reference line and require leveling to obtain a precise horizontal or vertical output beam. Other devices use a si...
