Abstract:
A crib platform device for use in providing a means for building a temporary buttress underneath an overhanging obstruction, said device comprising:a first platform unit comprising: a generally flat panel having a top surface, a bottom surface, a length and a width; and a plurality of elongated blocks attached to the top surface of said panel, each block having a width with a given thickness, a height, a length and an internal collar defining a hole traversing through the width of each block, wherein each block is aligned on said panel so that the holes in said plurality of blocks define an imaginary line, each block is also aligned substantially parallel to each other block and spaced apart from each other block by a distance of at least the given thickness of the width of each block whereby each pair of adjacent blocks defines a channel between each pair of adjacent blocks wherein the channel having a width of at least the given thickness of the width of any given block; a second platform unit comprising: a flexible strap; and a plurality of elongated beams attached to said flexible strap, each beam having a width with the given thickness, a height, a length and an internal sleeve defining an orifice traversing through the width of each beam, wherein each beam is aligned on said flexible strap so that the orifices in said plurality of beams lie along the imaginary line, each beam is also aligned substantially parallel to each other beam and spaced apart from each other beam by a distance of at least the given thickness of the width of each beam whereby each pair of adjacent beams defines a gap between each pair of adjacent beams having a width of at least the given thickness of the width of any given beam; and a lock bar comprising: a handle; and a rod attached to said handle, wherein said rod is slidably inserted within the hole of each block of said plurality of blocks of said first platform unit and slidably inserted within the orifice of each beam of said plurality of beams of said second platform unit, whereby locking said first and second platform units together.
