Adjustable work surface for large irregularly shaped objects
An adjustable work platform comprises a fixed platform carrying a multiplicity of adjustable members designed to slide out of the fixed platform to variable lengths as needed. A large irregularly shaped object, such as an aircraft, may be driven into the interior of the platform with the adjustable members retracted. Once in place, the adjustable members are extended to form a heavy duty work platform conforming to the irregular shape of the exterior of the object.
1. A work platform assembly for carrying heavy loads in a stable manner comprising:
a fixed platform with a front side and a back side opposite thereto comprising:
a first stringer along said front side comprising defined openings therein;
a second stringer along said back side; and
a multiplicity of I-beams functioning as guides spanning between said first stringer and said second stringer; and
an adjustable platform extendable from said fixed platform comprising:
a plurality of sliders, each said slider received by respective adjacent I-beam guides and disposed to reversibly extend through a respective one of said openings, each said slider comprising:
a toothed member attached to said slider that reversibly engages with said first stringer to restrict sliding of said slider and to permit sliding when not engaged;
a stop bar traversing said I-beam guides above said slider;
a back plate attached to said slider, to limit the length of extension of said slider beyond said stop bar, and;
said adjustable platform perimeter comprising three straight sides and a fourth side that is configurable between a straight or stepped edge.
2. The work platform of claim 1 wherein said toothed member is rotatable about a perpendicular axis to said toothed member.
3. The work platform of claim 1 wherein said toothed member is rotatable about a parallel axis to said toothed member.
4. The work platform of claim 1 wherein said back plate limits the lateral and vertical movement of said slider to provide increased stability of said slider.
