Abstract: An improved mechanism for the operation of multiple panels door with increased insulating properties comprises a means that keeps the door panels away from the seal as they move up or down vertically and that brings the panels tightly against the seal when the panels have completed their vertical course. In the prior art, a multiple panel door follows the path of the guide rail where in this instant invention, when the panels have run their course along the path of the guide rails, they are moved away from the guide rails and against the door frame, which results in the door panels to apply pressure against an insulating strip.

Abstract: Modular inflatable cover for buildings, comprising separate coaxial conduits (30) secured together by tensionable link (50) and fluid-connected by coaxial inflatable tube (24). Tube (24) securely embraces sliders (32) that in turn closely but freely embrace conduits (30). Sliders (32) are urged by springs (34) to keep tube (24) taught. Elastic cinctures (26) on tube (24) and springs (34) tensionably cooperate against inflation means to provide reliable control of openings between adjacent modules in an assembly. Conduits (30) are securely torqued to ground anchors (40) by coupling (42). End covers (44) and sliders (32) are provided to compensate for and facilitate length shrinkage of tube (24), upon inflation. The present invention provides a variable cover with integral support that is uniquely capable of exploiting canyons and other ground depressions for an unprecedented scale of environment control. Applications include greenhouses, shutters, insulation and shelters.
