Abstract
Abstract The invention is concerned with a shelving structure of the kind which is assembled from a number of vertical elements (struts) and interconnected horizontal elements (beams), and in particular to a shelf for such a shelving structure. Such shelves are conventionally formed from sheet metal, comprising a horizontal shelf panel and flanges extending vertically downwardly from the shelf panel on at least two sides thereof, each flange being folded backwardly on itself to increase the strength of the flange. In accordance with this invention, each flange is so folded as to provide a pocket in which an elongate reinforcing member is positioned, such reinforcing members engaging the underside of the shelf panel. In particular, each flange comprises a first portion extending downwardly from the panel, a second portion folded inwardly so as to extend towards the underside of the shelf panel generally parallel to, and spaced from the first portion, the reinforcing member being located between said first and second portions, transmitting load from the shelf by virtue of its engagement with the underside of the shelf and transmitting such load to an intermediate portion between said first and second portions.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
168 words
In a shelf formed from sheet material and comprising a generally rectangular shelf panel and flanges integral with the panel which flanges extend from the panel along two parallel sides thereof, each flange comprising a first portion extending downwardly from the panel, a second portion folded inwardly so as to extend towards the underside of the shelf panel generally parallel to the first portion, the improvement wherein said second portion is spaced from said first portion, and on each of the said sides of the panel a non-integral reinforcing member is located between said first and second portions of the flange, which reinforcing member extends upwardly, and into engagement with, the underside of the shelf panel, an upper end of said reinforcing member extending in angular relationship to the upwardly extending portion thereof and being in juxtaposition with said underside of the shelf panel to support the corner between the panel and the first portion of the flange along substantially the whole of the length of said side.
Claim 2
Dependent Claim
168 words
In a shelf formed from sheet material and comprising a generally rectangular shelf panel and flanges integral with the panel which flanges extend from the panel along two parallel sides thereof, each flange comprising a first portion extending downwardly from the panel, a second portion folded inwardly so as to extend towards the underside of the shelf panel generally parallel to the first portion, the improvement wherein said second portion is spaced from said first portion, and on each of the said sides of the panel a non-integral reinforcing member is located between said first and second portions of the flange, which reinforcing member extends upwardly, and into engagement with, the underside of the shelf panel, an upper end of said reinforcing member extending in angular relationship to the upwardly extending portion thereof and being in juxtaposition with said underside of the shelf panel to support the corner between the panel and the first portion of the flange along substantially the whole of the length of said side.
Claim 3
Dependent Claim
26 words
A shelf according to claim 1 wherein the flange comprises an intermediate portion between the first and second portions, on which the reinforcing member is seated.
Claim 4
Dependent Claim
12 words
A shelf according to claim 2 wherein said intermediate portion is flat.
Claim 5
Dependent Claim
44 words
A shelf according to claim 2 wherein said intermediate portion is curved, providing a part-cylindrical engagement surface facing towards the underside of the shelf panel, and the reinforcing member is provided with a similarly shaped engagement surface adapted to seat on said engagement surface.
Claim 6
Dependent Claim
39 words
A shelf according to claim 4 wherein the reinforcing member comprises first and second portions folded one against the other with an intermediate portion inter-connecting said first and second portions and providing said engagement surface of the reinforcing member.
Claim 7
Dependent Claim
43 words
A shelf according to claim 5 wherein the reinforcing member also comprises a transverse portion lying generally in a plane extending at right angles to the plane in which the first portion extends, and which engages with the underside of the shelf panel.
Claim 8
Dependent Claim

A shelf according to claim 1 wherein the shelf panel is square, and is provided with such flanges and reinforcing members on all four sides thereof.
Claim 9
Dependent Claim
39 words
A shelf according to claim 7 wherein reinforcing members of one thickness are provided along two of the sides of the shelf, and reinforcing members of a different thickness are provided along the other two sides of the shelf.
Claim 10
Dependent Claim
32 words
A shelf according to claim 1 wherein the reinforcing members are formed of metal of a different thickness and/or of different physical characteristics to that which constitutes the remainder of the shelf.
