A shelving assembly comprising a vertical back member for arrangement in an aligned row with the other back members, said back member including a pair of spaced-apart plates and a pair of end columns disposed between and connected to said pair of plates, each of said columns including a first portion having a plurality of aligned slots therein and a second portion having a plurality of aligned lances therein, means for supporting said back member in a freestanding vertical position including a gusset disposed transversely of said spaced-apart plates including a vertically disposed web, first supporting members secured to said web, each of said first supporting members including a flat portion partially defined by lateral edges, each of said columns including a lower end and means at said lower end defining openings in said second portions, which openings are partially defined by lateral edges which bear on the lateral edges of said flat portions to support said columns, and each of said columns including a plate portion secured to said second portion at the lower end thereof, said second portion being offset in the area of said plate portion to accommodate the thickness of said plate portion and at least a portion of the thickness of said web, said plate portion having openings therein which are generally aligned with the openings in said second portion and of a shape to accommodate said flat portions in the same plane therewith, and shelf means including a pair of shelf-supporting brackets for mounting on said end columns, each of said brackets including rearwardly extending tab means for insertion into the slots of said first portion and for bearing against the lances of said second portion. 2. The shelving assembly set forth in claim 1, wherein said columns are U-shaped and each of said second portion thereof is the base portion of the U, and said lances are directed inwardly of the U.
Claim 2
Dependent Claim
69 words
The shelving assembly set forth in claim 1, wherein said tab means includes a plurality of tabs at least some of said tabs including an upper edge for bearing against said lances and a lower edge including a slot therein vertically aligned with similar slots of the other tabs for receiving the edges of the slots in said first portion of said columns when said tabs are inserted therein.
Claim 3
Dependent Claim
48 words
The shelving assembly set forth in claim 3, wherein said plurality of tabs includes a plurality of angularly aligned slots in said lower edges thereof for receiving the edges of the slots in said first portion when said tabs are inserted therein at an angle to the horizontal.
Claim 4
Dependent Claim
64 words
The shelving assembly set forth in claim 1, wherein said means defining openings includes upper edges which partially define the openings and wherein each of said outwardly extending portions of said supporting members include a horizontally disposed cup-shaped segment for receiving said upper edges of said openings in said columns, and an angularly directed segment for guiding said Upper edges into said cup-shaped segment.
Claim 5
Dependent Claim
61 words
The shelving assembly set forth in claim 1, wherein said supporting means includes leveling screw means threadedly engaging said gusset, said screw means including a head portion for contacting a supporting surface and an elongate threaded portion engaging said gusset, and each said column includes a slot in the lower edge thereof to prevent interference between said screw and said column.
Claim 6
Dependent Claim
40 words
The shelving assembly set forth in claim 1, wherein said lateral edges of said flat portions of said first supporting members are disposed to define a point of convergence thereabove and guide said column during assembly to the supporting means.
Claim 7
Dependent Claim
38 words
The shelving assembly set forth in claim 7, wherein the openings in each of said plates are partially defined by edges which conform to and bear against the guiding edges of said flat portions of said supporting members.
