Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 272 words
A mobile isolation module in the form of a cubicle enclosure of rectangular, horizontal and vertical cross section comprising a bottom wall, a top wall and quadrilaterally-disposed side walls which collectively define a closed chamber, one of said side walls containing a rectangular opening for entrance into the chamber, a panel of corresponding rectangular configuration disposed in said opening, zipper fastener means connecting the panel within said opening to provide access through said opening to the enclosure and to seal the enclosure when in use, means providing an opening in the top wall for exit from the chamber at the top, comprising quadrilaterally-arranged panels formed in the top wall of triangular configuration, the adjacent sides of which are diagonal to the top and the apices of which meet at the center of the top, zipper fastening means joining the adjacent edges of the panels such as to enable variably disconnecting the adjacent edges of the panels to provide an opening at the top of adjustable size, vacuum generating means connected to the chamber through one side wall to enable lowering the pressure therein, a mobile platform, an adjustable frame comprised of quadrilaterally-disposed posts fixed at their lower ends to the platform upon which the enclosure is disposed, said frame being adjustable heightwise to a height corresponding to the height of the ceiling and said side wall panels being comprised of flexible material of a sufficient length heightwise of the module to be extended by adjustment of the frame to the ceiling height and means for mobilizing the platform and, hence, the module, comprising casters mounted to the platform at the four corners.
