Abstract:
1. A removable assembly for covering an opening comprising: a compression withstanding, structural, cover plate having peripheral dimensions slightly larger than the opening to be covered, said cover plate comprising a plurality of marginally located fulcrum holes paired in longitudinal opposition to one another; a plurality of ratcheting attachment assemblies, each said ratcheting attachment assembly comprising a pair of clamping levers having a first end for fixedly attaching to a tension transmitting means, a second end for engagement with a structural member and an arcuate midsection defined therebetween, wherein said first end, said second end, and said arcuate midsection define a curved shape visible from a first two opposing directions, and wherein said first end, said second end, and said arcuate midsection define a straight shape visible from a second two opposing directions, said second two opposing directions perpendicular to said first two opposing directions, said arcuate midsection for bearing against a fulcrum opening in a respective cover member; a ratcheting device comprising a body, said body carried between said pair of clamping levers; a first said tension transmitting means terminated at a first end by fixedly connecting to said clamping lever, and a second, free end for adjustably wrapping around a drum of said ratcheting device; a second said tension transmitting means terminated at a first end by a second said clamping lever, and terminated at a second end by fixedly attaching to the said body of said ratcheting device; whereby each said clamping lever can be rotatably engaged respectively to a first and second fulcrum point on said cover member to provide fine adjustment of length and the development of compressive force against respective said structural members, with each said pair of said clamping levers inserted respectively through said paired fulcrum holes, whereby said holes are positioned as required for said clamping levers to generate paired moment couples about the hole as a fulcrum point for said second end of said clamping levers to provide a clamping action to an interior edge of said opening by clamping said clamping levers between said structural cover plate and-said interior edge.
