Portable scissor-lift-assembly

A portable assembly for lifting an operator along a vertical plane, said assembly comprising:

• a first platform provided with a planar top surface and having a centrally registered longitudinal axis, said first platform further having a pair of opposed sides equidistantly spaced from the longitudinal axis and traveling parallel thereto, said first platform including a plurality of wheels and a plurality of brackets operably connected thereto wherein said wheels and said brackets extend outwardly from one said sides and having an axis of rotation situated orthogonal thereto, said wheels and said brackets being spaced at opposed end portions of said platform;
• a plurality of rectilinear support shafts having opposed end portions securely conjoined to said platform and extending upwardly therefrom along a vertical axis situated orthogonal to the longitudinal axis, said rectilinear support shafts being equidistantly spaced at opposed corners of said platform;
• a pair of inverted U-shape guide rails telescopically engageable along a longitudinal length of said support shafts, each said guide rails having a pair of monolithically formed rectilinear regions slidably positionable about said support shafts such that said guide rails can be raised and lowered along a predetermined vertical path during operating conditions;
• a second platform provided with planar top and bottom surfaces and having a plurality of apertures formed at opposed corners thereof, said apertures being vertically registered with said support shafts and receiving said support shafts therethrough such that said second platform can be raised and lowered in sync with said guide rails, said first and second platforms being coextensive;
• and
• lifting means for vertically biasing said second platform and said guide rails along a longitudinal length of said support shaft, said lifting means being securely connected to said top surface of said first platform and said bottom surface of said second platform;
• wherein said assembly can be rotated about said one side in such a manner that said wheels become operably engaged with a ground surface while said first and second platforms become oriented perpendicularly to the ground surface and thereby allowing the operator to quickly and readily transport said assembly between remote locations.
