Abstract: A dual use device adapted to define a furniture component when in a stored state and provide access to a cover for covering a furniture item when in a covering state. The device includes an enclosure with a plurality of enclosure panels, the enclosure panels being connected as to define a shape of the furniture component. The connection between at least some of the enclosure panels is through detachable attachments which permit access to an internal space within the enclosure. A cover for covering a furniture item is foldably received within the internal space when the dual use device is in its stored state and the dual use device serves as a furniture component. The cover adapted to be extracted from the internal space and unfolded to cover the furniture item when the dual use device is in its covering state.

Abstract: A fast assembly and disassembly shed comprises multiple prefabricated wall panels, multiple prefabricated roof panels, multiple prefabricated floor panels, and multiple quick assembly connectors. These prefabricated wall panels can be quickly assembled or disassembled to enclose a space. These prefabricated roof panels can be quickly assembled or disassembled onto the upper edge of the prefabricated wall panels to cover the space. These prefabricated floor panels can be quickly assembled or disassembled onto the lower edge of the prefabricated wall panels. The quick assembly connectors are placed between any two adjacent elements among the prefabricated wall panels, prefabricated roof panels, and prefabricated floor panels to secure their relative positions.
