ABSTRACT:
An apparatus includes a first tray slidably received within a second tray, wherein the first tray and the second tray each are formed with a planar floor and upstanding flanges orthogonally and coextensively mounted to spaced parallel edges of each floor. Each floor includes an enclosed longitudinally aligned slot, wherein the slots overlie each other when the first shield is slidably received within the second shield to fixedly position the first shield relative to the second shield in an adjustable manner. Each shield includes at its forward end a first and second "U" shaped recess, the recesses aligned relative to one another to complementarily receive door framework contours of opposed door frames to provide a shield overlying an interface between room portions directed through a portal. A modification of the instant invention includes suspension hooks mounted to flexible lines, wherein the lines include spools to adjust the length of the lines to provide shielding in an adjustable manner relative to an upper end of the associated portal. A further modification includes flexible fingers aligned and parallel to one another formed with the aforenoted aligned slots mounted to forward ends of each of the relatively movable sections to accommodate contour variations within door framework portals.
