2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 1.98
It is known in prior art to provide articles of furniture with foldable walls and major components which may be reduced to a compact, knock-down condition for storage and shipment. The walls and shelves are hingedly connected together so that they may be quickly assembled and also disassembled and returned to the compact condition for further storage or shipment. Examples of foldable ready-to-use entertainment stand devices may be found in U.S. Pat. Nos. 6,039,419 and 6,722,750. These however do not provide secured folding side walls. Each movable wall is connected on one side only and therefor is more apt to become damaged. The prior patents lack a completely rigid assembled cabinet structure foldable and connectable without tools.
U.S. Pat. No. 6,848,758, issued Feb. 1, 2005 to Yeh et al, is for a Do-It-Yourself (DIY) modular cabinet. The DIY cabinet has a foldable frame, a top panel, a bottom panel, a rear panel and multiple pop-it fasteners. The panels are attached to the foldable frame with the pop-it fasteners. Each pop-it fastener is composed of a countersunk tube and a stud. The countersunk tubes are pressed into head holes in panels, and the studs are screwed into and extend from base holes in the foldable frame and align with corresponding head holes in the panels. The studs extending from the base holes are pressed respectively into the countersunk tube in the head holes. Thereby, the panels are conveniently mounted on the foldable frame without using any tools. Moreover, the foldable frame can be folded to reduce the size of the disassembled DIY cabinet.
U.S. Pat. No. 6,039,419, issued Mar. 21, 2000 to Brown et al., describes a preassembled, foldable entertainment stand for a computer printer and the like having a folded and erect configuration wherein a vertical back panel pivotally carries a plurality of vertical shelf panels. The shelf panels fold upwardly to a generally vertically position disposed near the front surface of the back panel while a top shelf panel folds upwardly to overlay the rear surface of the back panel. A pair of side panels are pivotally carried by the back panel. Panel hinges with displaced pivots secure the top panel and the side panels to the back panel so that the top panel lies flush against the back panel and the side panels fold generally flat over the shelf panels when the stand is folded for a compact folded configuration.
U.S. Pat. No. 6,948,787, issued Sep. 27, 2005 to McBrayer, III et al, provides a folding wardrobe with an integral hinge assembly. The foldable sheet metal wardrobe has a front wall, a rear wall, a foldable right side wall, a foldable left side wall, a top member, and a bottom member defining an inner wardrobe space when the wardrobe is in an open position. A left and a right unitary front side panel, each of the unitary front side panels has a first section of a closed loop hinge assembly integrally formed in the sheet metal of the front side panel. The first integral hinge section has an offset stiffener member. A left and right unitary rear side panel, each of the unitary rear side panels has a second, complimentary closed loop hinge assembly section integrally formed in the sheet metal of the rear side panels. The second integral hinge section also has an offset stiffener member. Each of the front side and the rear side panels are connected along the first and second sections by a single continuous steel hinge pin to join the sections into single foldable left and right hinged side walls. The wardrobe hinges are stronger and more secure from exposure to unauthorized entry.

Each of the foldable plank assemblies includes two planks pivotally connected with each other. One of the planks of each of the foldable lateral plank assemblies is pivotally connected with the front frame. The other of the planks of each of the foldable lateral plank assemblies is pivotally connected with the rear frame.
U.S. Patent Application #20080084149, published Apr. 10, 2008 by Ho, claims a collapsible cabinet which includes a body, two doors, a cover and a bottom member. The body includes two inner panels, two inner posts, two outer panels and two outer posts. All panels and posts of the body are hinged to each other. Each door is hinged detachably to one of the outer posts of the body. The cover is mounted detachably on the body. The bottom member is mounted detachably in the body. Because each door is hinged detachably to one of the outer posts of the body, the collapsible cabinet can be assembled and detached easily without using tools. Labor cost and assembling time of the collapsible cabinet can also be reduced. When the collapsible cabinet is detached, the collapsible cabinet can be transporting and storing easily and cost therefor can be reduced.
