Abstract
Abstract A shelving structure is disclosed, wherein space-enclosing side panels can be secured between assembled legs and shelves. The legs are provided with inset inner perimeter sections which form flanges spaced apart from the shelf margins. Between the flanges and the shelf margins, the panels are secured. The shelves are attached to the legs by novel brackets which are preliminary attached to the shelves by dogleg-shaped tangs.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
147 words
A shelving structure comprising at least one elongated leg member having an outer perimeter section and an inner perimeter section inset with respect to the outer perimeter section to form at least one leg flange, a margined shelf member having skirt portions extending along the shelf margin and a cutaway corner portion adapted to mate with only a portion of said leg inner perimeter section for orienting the shelf margin adjacent to, but spaced apart from, the leg flange by a predetermined distance, said predetermined distance between the leg flange and the shelf skirt substantially equalling the thickness of a panel member thereby permitting the insertion of the panel member between the leg flange and the shelf margin and retention of the panel member between the leg flange and the shelf margin, and shelf-leg connecting means for mounting the shelf to the leg at a predetermined location.
Claim 2
Dependent Claim
147 words
A shelving structure comprising at least one elongated leg member having an outer perimeter section and an inner perimeter section inset with respect to the outer perimeter section to form at least one leg flange, a margined shelf member having skirt portions extending along the shelf margin and a cutaway corner portion adapted to mate with only a portion of said leg inner perimeter section for orienting the shelf margin adjacent to, but spaced apart from, the leg flange by a predetermined distance, said predetermined distance between the leg flange and the shelf skirt substantially equalling the thickness of a panel member thereby permitting the insertion of the panel member between the leg flange and the shelf margin and retention of the panel member between the leg flange and the shelf margin, and shelf-leg connecting means for mounting the shelf to the leg at a predetermined location.
Claim 3
Dependent Claim
79 words
A shelving structure according to claim 1 wherein said shelf-leg connecting means includes a stud member having a head and a stem and affixed to said leg member, and a slotted bracket member adapted to engage said shelf skirts and further adapted to slidE over the stud stem with the stud head at least partly covering the bracket slot to locate at least one shelf skirt at a position spaced apart from said leg flange by said predetermined distance.
Claim 4
Dependent Claim
102 words
A shelving structure according to claim 2 wherein said slotted bracket is provided with tangs for engaging said shelf skirts, at least two tangs taking the form of outwardly extending offset doglegs for engaging and initially retaining the bracket member between adjacent skirt portions of said shelf, and at least two tangs taking the forms of finger inserts for engaging the skirt portions and extending generally perpendicularly to the ends of said outwardly extending offset doglegs, said tangs cooperating to draw the bracket member and engaged skirt portions toward said leg member as said stud head is moved toward said leg member.
Claim 5
Dependent Claim
54 words
a shelving structure according to claim 1 wherein a plurality of shelves are mounted to said leg at a corresponding plurality of locations spaced apart along said leg, and further including panel members extending between adjacent shelves to at least partially enclose a volume of space between said panel members and said shelf members.
Claim 6
Dependent Claim
36 words
A shelving structure according to claim 4 including a leg member having two leg flanges, thereby permitting the insertion and retention of at least two panel members between said leg member and shelf members mounted thereto.
Claim 7
Dependent Claim
26 words
A shelving structure according to claim 4 wherein said panel members are secured between said leg member flanges and said shelf member by an interference fit.
Claim 8
Dependent Claim
43 words
A shelving structure according to claim 1 wherein said leg member is a hollow, single continuous sheet member, the edges of said single sheet forming said leg being interlocked in a continuous pressed knuckle grip extending substantially the entire length of the leg.
