A multi-beam tool is disclosed which can perform square, plumb, and level function which may be required in a construction environment. The tool can generate in a preferred embodiment up to five orthogonal beams with two beams being plumb and three beams being leveled. Combinations of two level beam
A multi-beam tool is disclosed which can perform square, plumb, and level function which may be required in a construction environment. The tool can generate in a preferred embodiment up to five orthogonal beams with two beams being plumb and three beams being leveled. Combinations of two level beams, or a level and a plumb beam in orthogonal arrangement can produce a square alignment set of beams. The tool includes in a preferred arrangement a self-leveling pendulum to which a laser and quad-mirror arrangement is secured. The self-leveling pendulum is damped in order to allow the tool to settle down and provide alignment after the tool is positioned as desired. The quad-mirror, the magnetic damping, and the coiled wire allowing power to be provided to the laser assembly, each separately, and also in combination, provide for a compact tool.

The apparatus of claim 2, said handle having one end and another end, said one end of said handle being elastically mounted to said first support frame for allowing insertion and removal of said another end from said curved guide hole. 7. The apparatus of claim 6, further comprising: a cubic space formed in a portion of said first support frame for holding said one end of said handle; and a spring engaged in an interior of said cubic space and elastically supported by one side of the cubic space and said one end of said handle for providing elastic mounting of the handle. 8. The apparatus of claim 2, further comprising: a rack gear protruding from an upper end of said first support frame in a perpendicular direction relative to said first support frame; and a pinion gear for engaging said rack gear, said pinion gear being mounted with tension to said first plate. 9. The apparatus of claim 8, said first plate having a knob hole; and said apparatus further comprising an adjusting knob having a shaft, said adjusting knob being positioned on an outer surface of said first plate, and said shaft penetrating said knob hole and being axially engaged with said pinion gear. 10. The apparatus of claim 9, further comprising a fixing hole which is longitudinal in shape for allowing an end of said handle to be moveable when accepted in said fixing hole. 11. The apparatus of claim 1, said curved guide hole being positioned to allow pivoting of said half-mirror so as to be parallel with said first image display apparatus. 12. The apparatus of claim 1, said fixing hole being longitudinal in shape for allowing an end of said handle to be moveable when accepted in said fixing hole. 13. A three-dimensional image display apparatus, comprising: a casing which includes a lower portion for engaging a first image display apparatus, and a rear portion for engaging a second image display apparatus perpendicular to said first image display apparatus; first and second plates respectively mounted at opposite sides of the casing; a hinge shaft extending between said first and second plates, an axis of the hinge shaft intersecting each of the first and second plates near a comer of said each of the first and second plates corresponding to an intersection of the lower and rear portions of the casing; a half-mirror connected to said hinge shaft along a lower edge of the half-mirror, said half-mirror being adjustably mounted in said casing so as to be pivotable about said hinge shaft; first and second support frames for supporting said half-mirror, each of said support frames being mounted to an edge of said half-mirror between said half-mirror and a corresponding one of said plates, said support frames being mounted to said hinge shaft to form the connection of said half-mirror to said hinge shaft; a rack gear protruding from an upper end of said first support frame in a perpendicular direction relative to said first support frame; and a pinion gear for engaging said rack gear, said pinion gear being mounted with tension to said first plate. 14. The apparatus of claim 13, said first plate having a knob hole; and said apparatus further comprising an adjusting knob having a shaft, said adjusting knob being positioned on an outer surface of said first plate, and said shaft penetrating said knob hole and being axially engaged with said pinion gear. 15. The apparatus of claim 13, said first plate having a curved guide hole for guiding pivoting of said half-mirror, said apparatus further comprising a handle attached to said first support frame and extending through said curved guide hole. 16. The apparatus of claim 15, said handle being formed in a bent shape and having one end of the handle attached to said first support fra me and another end of the handle pointing back toward said first support frame; and said first plate having a fixing hole near an upper end of said curved guide hole for accepting said another end of said handle. 17. The apparatus of claim 16, further comprising a fixing hole which is longitudinal in shape for allowing said another end of said handle to be moveable when accepted in said fixing hole. 18. A three-dimensional image display apparatus, comprising: a casing which includes a lower portion for engaging a first image display apparatus, and a rear portion for engaging a second image display apparatus perpendicular to said first image display apparatus; first and second plates respectively mounted at opposite sides of the casing; a hinge shaft extending between said first and second plates, an axis of the hinge shaft intersecting each of the first and second plates near a comer of said each of the first and second plates corresponding to an intersection of the lower and rear portions of the casing; and a half-mirror connected along a lower edge of the half-mirror to said hinge shaft, said half-mirror being adjustably mounted in said casing so as to be pivotable about said hinge shaft; wherein said second plate has a curved guide hole for guiding pivoting of said half-mirror; said apparatus further comprising an additional handle attached to said second support frame and extending through said curved guide hole of said second plate; said additional handle being formed in a bent shape, and having one end attached to a support frame and another end pointing back toward the support frame; and each of said first and a second plates having a fixing hole for accepting said another end of said additional handle. 19. The apparatus of claim 18, further comprising: first and second support frames for supporting said half-mirror, each of said support frames being mounted to an edge of said half-mirror between said half-mirror and a corresponding one of said plates, said support frames being mounted to said hinge shaft to form the connection of said half-mirror to said hinge shaft. 20. A three-dimensional image display apparatus, comprising: a casing which includes a lower portion for engaging a first image display apparatus, and a rear portion for engaging a second image display apparatus perpendicular to said first image display apparatus; first and second plates respectively mounted at opposite sides of the casing; a hinge shaft extending between said first and second plates, an axis of the hinge shaft intersecting each of the first and second plates near a comer of said each of the first and second plates corresponding to an intersection of the lower and rear portions of the casing; and a half-mirror connected along a lower edge of the half-mirror to said hinge shaft, said half-mirror being adjustably mounted in said casing so as to be pivotable about said hinge shaft; said first plate having a curved guide hole for guiding pivoting of said half-mirror, said apparatus further comprising a handle attached to said first support frame and extending through said curved guide hole; and said apparatus further comprising a support frame and a handle having one end elastically mounted to said support frame for allowing insertion and removal of said another end of said handle from said curved guide hole. 21.
