  • Patent number: 5662399
    Abstract: A ready-to-assemble cabinet including two upstanding side panels, at least two fixed shelves between the side panels, a folding back panel attached to the side panels, and hardware for holding the components together. The cabinet may optionally include additional fixed and adjustable shelves. The back panel is preattached to the side panels by the manufacturer to create a back panel/side panel sub-assembly. The back panel includes a number of vertically scored fold lines running from top to bottom, which delineate longitudinal sections of the back panel. The scored fold lines permit the sub-assembly to be folded accordion-style for packaging, whereby the back panel sections are sandwiched between the side panels. Serrated plastic dowel pins hold the shelves to the side panels to eliminate the need for tools and/or adhesives and permit assembly of the cabinet in only three to five minutes.
