Abstract
A kit that includes a base with a floor and four edges; a cover with a ceiling and four edges; and, four side panels, at least one of which is a framed air filter. The kit may be nestable. The kit is assemblable into an upwardly-open, horizontally-closed air-filtration assembly. The floor of the base may include multiple through-cuts and hinged connections that define multiple areas of the floor that are rotatable upward to provide multiple upwardly-protruding tabs; the ceiling of the cover may include multiple through-cuts and hinged connections that define multiple areas of the ceiling that are rotatable downward to provide multiple downwardly-protruding tabs.
Claims20
A kit that is assemblable to provide a disassemblable air-filtration assembly, the kit comprising:
- a square base that comprises a floor with an upward-facing surface and that comprises a perimeter with four edges;
- four rectangular side panels, at least one of which is a framed air filter;
- and,
- a square cover that comprises a partial ceiling with a downward-facing surface and that comprises a perimeter with four edges,
- wherein the kit is configured so that it is assemblable into a disassemblable air-filtration assembly comprising the base, the cover, and the four side panels, with lower edges of the side panels abutted against the upward-facing surface of the floor of the base and with upper edges of the side panels abutted against the downward-facing surface of the partial ceiling of the cover, so that the base, the four side panels, and the cover collectively form an upwardly-open, horizontally-closed air-filtration assembly that is in the shape of a cuboid and that defines a filtered-air cavity within the assembly,
- and,
- wherein the floor of the base comprises multiple through-cuts and hinged connections that define multiple areas of the floor that are rotatable upward to provide multiple upwardly-protruding tabs and the ceiling of the cover comprises multiple through-cuts and hinged connections that define multiple areas of the ceiling that are rotatable downward to provide multiple downwardly-protruding tabs, and wherein the kit is provided with all of the areas of the floor and ceiling that are rotatable to form protruding tabs, in non-rotated positions in which they are respectively flush with the floor and the ceiling, the areas of the floor and ceiling being rotatable into rotated positions in which they respectively form the upwardly-protruding tabs and the downwardly-protruding tabs that, in the air-filtration assembly, hold the lower edges of the side panels in place between the upwardly-protruding tabs and upwardly-extending edge flanges of the base and hold the upper edges of the side panels in place between the downwardly-protruding tabs and downwardly-protruding edge flanges of the cover.
