Continuous cascade shelving assembly of knockdown character

Claim 2

In an assembly of continuous knockdown cascade shelving, a unit length of shelving comprising a pair of vertically disposed, flat, parallel, spaced apart, wall-forming end pieces of similar configuration, each end piece having a vertical stem portion provided with forwardly projecting webs which are vertically spaced from one another, the inner faces of said end pieces being provided thereon with opposed pairs of ledge-forming Supporting strips which are inclined forwardly and downwardly, each strip extending from a region adjacent to the rear edge of its prespective end piece to a region adjacent to the forward end of one of said webs, each strip being rectangular in transverse cross section, the upper corner edges of the strip in the vicinity of the adjacent end pieces being relieved so as to define, in combination with such end piece, an upwardly facing channel which is coextensive with the strip, such strip further being generally L-shape in longitudinal extent so as to provide a relatively long forwardly and downwardly inclined leg and a relatively short forwardly and upwardly inclined foot portion, and an inclined cascade unit bridging the distance between each opposed pair of webs, said cascade unit being provided with vertical side walls and a stepped bottom wall, the lower edges of said side walls projecting downwardly below the level of said bottom wall and being conformably shaped with respect to and seated coextensively within an adjacent channel thereby preventing lateral separation of the end pieces from the units said cascade unit being further provided with a vertical rear wall having grooves formed coextensively in its upper and lower edges, and a vertically disposed backboard of rectangular configuration interposed between adjacent cascade units and having its upper edge removably projecting into the groove which is provided in the lower edge of the rear wall of an upper cascade unit and its lower edge removably projecting into the groove which is provided in the upper edge of the rear wall of the next adjacent lower cascade unit.

Claim 3

In an assembly of continuous knockdown cascade shelving, in combination, a plurality of unit lengths of shelving disposed in side-by-side longitudinal relationship, said assembly comprising a plurality of vertically disposed, flat, parallel, spaced apart, wall-forming end pieces of similar configuration, each end piece having a vertical stem portion provided with forwardly projecting webs which are vertically spaced from one another, said end pieces establishing a pair of end walls and at least one intermediate divider wall, the inner face of each end wall and both faces of each divider wall being provided thereon with a plurality of ledge-forming supporting strips, each strip extending from a region adjacent to the rear edge of its respective end piece to a region adjacent to the forward end of one of said webs, the strips being rectangular in transverse cross section with the upper corner edges thereof in the vicinity of the adjacent end pieces being relieved so as to define, in combination with such end pieces, upwardly facing channels which are coextensive with the strips, the strips further being generally L-shape in longitudinal extent so as to provide relatively long forwardly and downwardly inclined legs and relatively short forwardly and upwardly inclined foot portions, said strips being disposed in parallelism and with the strips on adjacent end pieces being disposed in opposed pairs, and an inclined tray-like cascade unit bridging the distance between the webs of each pair of adjacent end pieces, said cascade unit being provided with vertical side walls and a stepped bottom wall, the lower edges of said side walls projecting downwardly below the level of said bottom wall and being conformably shaped with respect to and seated coextensively within an adjacent channel thereby preventing lateral separation of the end pieces from the units said cascade unit being further provided with a vertical rear wall having grooves formed coextensively in the upper and lower edges thereof, and a vertically disposed backboard of rectangular configuration interposed between adjacent cascade trays and having its upper edge removably projecting into the groove which is provided in the lower edge of the rear wall of an upper cascade unit and its lower edge removably projecting into the groove which is provided in the upper edge of the rear wall of the next adjacent lOwer cascade unit.

Claim 4

In an assembly of continuous knockdown cascade shelving, in combination, a plurality of unit lengths of shelving disposed in side-by-side longitudinal relationship, said assembly comprising a plurality of vertically disposed, flat, parallel, spaced apart, wall-forming end pieces of similar configuration, each end piece having a vertical stem portion provided with forwardly projecting webs which are vertically spaced from one another, said end pieces establishing a pair of end walls and at least one intermediate divider wall, the inner face of each end wall and both faces of each divider wall being provided thereon with a plurality of ledge-forming supporting strips, each strip extending from a region adjacent to the rear edge of its respective end piece to a region adjacent to the forward end of one of said webs, the strips being rectangular in transverse cross section with the upper corner edges thereof in the vicinity of the adjacent end pieces being relieved so as to define, in combination with such end pieces, upwardly facing channels which are coextensive with the strips, the strips further being generally L-shape in longitudinal extent so as to provide relatively long forwardly and downwardly inclined legs and relatively short forwardly and upwardly inclined foot portions, said strips being disposed in parallelism and with the strips on adjacent end pieces being disposed in opposed pairs, and an inclined tray-like cascade unit bridging the distance between the webs of each pair of adjacent end pieces, said cascade unit being provided with vertical side walls and a stepped bottom wall, the lower edges of said side walls projecting downwardly below the level of said bottom wall and being conformably shaped with respect to and seated coextensively within an adjacent channel thereby preventing lateral separation of the end pieces from the units said cascade unit being further provided with a vertical rear wall having grooves formed coextensively in the upper and lower edges thereof, and a vertically disposed backboard of rectangular configuration interposed between adjacent cascade trays and having its upper edge removably projecting into the groove which is provided in the lower edge of the rear wall of an upper cascade unit and its lower edge removably projecting into the groove which is provided in the upper edge of the rear wall of the next adjacent lOwer cascade unit.
