Abstract
Abstract Plastic box furniture is made up of at least one rectangular box member open on at least one side. The box member is constructed of individual side panels fitted together along adjoining edges and secured together around the periphery of the open side by a frame. Preferably, the side panels are made of a hollow construction, formed by a pair of spaced wall members joined together along their edges to provide ribs or grooves for interconnecting the panels. Each of the panels can be provided with openings to receive bolt-like members for securing separate box members together in a furniture arrangement. The box member can be arranged to receive a drawer inserted through its open side, or the open side can be closed by a door or a cover.

Claim 1
Independent Claim
433 words
Box-type furniture comprising at least one rectangular box member having at least one open side, said box member comprising four wall panels each forming a closed side of said rectangular box member with the adjoining edges of said panels being interconnected, a frame member having an angular sectional shape defining the periphery of the open side of said box member and the edges of said wall panels located along the edges of the open side of said box member are secured within said frame, a rear member located at the opposite side of said box member from said open side and having a frame-like section in which the edges of said wall panels along the opposite side are fitted, said wall panels, said frame member and said rear member are formed of plastic, each said wall panel comprises a pair of parallel thin wall sections in contacting engagement about the peripheral edges thereof and spaced apart inwardly of the peripheral edges and forming a closed hollow space therebetween, said wall sections having aligned openings therethrough, means located at said openings and extending through the hollow space therebetween providing bearing between said wall sections, said wall panels comprising a pair of first panels disposed in spaced parallel relationship and a pair of second panels disposed in spaced parallel relationship and extending between the edges of said first panels, the edges of said first panels bordering said second panels having laterally extending ribs formed therealong and the edges of said second panels bordering said first panels having grooves formed therein and arranged to receive the ribs on said first panels in interengaged relationship, the contacting edge portions of said first and second panels bordering the contacting edge portions of said first and second panels bordering the open side of said box member forming ribs which extend laterally outwardly from said first and second members and fit into said frame, the surfaces of said laterally extending ribs on said first and second panels bordering the open side of said box member have the inwardly faCing surfaces spaced outwardly from the corresponding inwardly facing surfaces of said panels and have the outwardly facing surfaces of said ribs spaced inwardly from the corresponding outwardly facing surfaces of said panels, the ends of said ribs extending laterally from said first and second panels are disposed in contact with the ends of said ribs extending laterally from the adjoining said wall panels and each said laterally extending rib is formed by two parallel contacting flanges and each of said flanges is formed on a different one of said wall sections.
Claim 2
Dependent Claim
433 words
Box-type furniture comprising at least one rectangular box member having at least one open side, said box member comprising four wall panels each forming a closed side of said rectangular box member with the adjoining edges of said panels being interconnected, a frame member having an angular sectional shape defining the periphery of the open side of said box member and the edges of said wall panels located along the edges of the open side of said box member are secured within said frame, a rear member located at the opposite side of said box member from said open side and having a frame-like section in which the edges of said wall panels along the opposite side are fitted, said wall panels, said frame member and said rear member are formed of plastic, each said wall panel comprises a pair of parallel thin wall sections in contacting engagement about the peripheral edges thereof and spaced apart inwardly of the peripheral edges and forming a closed hollow space therebetween, said wall sections having aligned openings therethrough, means located at said openings and extending through the hollow space therebetween providing bearing between said wall sections, said wall panels comprising a pair of first panels disposed in spaced parallel relationship and a pair of second panels disposed in spaced parallel relationship and extending between the edges of said first panels, the edges of said first panels bordering said second panels having laterally extending ribs formed therealong and the edges of said second panels bordering said first panels having grooves formed therein and arranged to receive the ribs on said first panels in interengaged relationship, the contacting edge portions of said first and second panels bordering the contacting edge portions of said first and second panels bordering the open side of said box member forming ribs which extend laterally outwardly from said first and second members and fit into said frame, the surfaces of said laterally extending ribs on said first and second panels bordering the open side of said box member have the inwardly faCing surfaces spaced outwardly from the corresponding inwardly facing surfaces of said panels and have the outwardly facing surfaces of said ribs spaced inwardly from the corresponding outwardly facing surfaces of said panels, the ends of said ribs extending laterally from said first and second panels are disposed in contact with the ends of said ribs extending laterally from the adjoining said wall panels and each said laterally extending rib is formed by two parallel contacting flanges and each of said flanges is formed on a different one of said wall sections.
Claim 3
Dependent Claim
173 words
Box-type furniture, as set forth in claim 1, wherein said frame comprises a U-shaped section formed of a plurality of interconnected elongated legs with a first one of said legs forming the bight portion of said U-shaped section being located in the plane of the open side of said box member, a second one of said legs secured to the outer longitudinally extending edge of the first one of said legs and extending therefrom toward the side of said box member opposite the open side, and a third one of said legs disposed in substantially parallel relationship with the second one of said legs and secured to the inner longitudinally extending edge of the first one of said legs and extending therefrom toward the side of said box member opposite the open side thereof so that the first, second and third ones of said legs combine in providing a longitudinally extending groove into which the edges of said wall panels located along the edge of the open side of said box are secured.
Claim 4
Dependent Claim
189 words
Box-type furniture, as set forth in claim 2, wherein the outer surface of the second one of said legs of said frame is located in the plane of the exterior surface of the one of said first and second panels along which said frame extends, and the inner surface of the third one of said legs of said frame is located in a plane spaced outwardly from the plane of the inner surface of the one of said first and second panels along which said frame extends, said rear member comprises a rear panel positioned opposite the open side of said box member and the peripheral edge of said rear panel spaced more remotely from said open side of said box member is recessed inwardly so that its outer surface is approximately in the same plane as the inwardly facing surface of the third one of said legs so that said rear panel is insertable within said frame at the open side of another said box member for stacking said boxes in a nested arrangement whereby the interior surfaces of said box members are aligned in the same planes.
Claim 5
Dependent Claim
38 words
Box-type furniture, as set forth in claim 1, wherein said rear member comprises a rear wall section integral with said frame-like section thereof for forming a closure across the side opposite the open side of said box member.
Claim 6
Dependent Claim
