Abstract

Abstract This invention relates to a sheet metal shelving comprising posts and shelves. The posts include a waist which by means of a first flange is connected to a second flange. The waist abuts a first edge part of the shelf whereas the second flange engages recesses in a second edge part of the shelf. The second edge part forms a closed torsion resistant profile with several in vertical direction separated extending flanges having said recesses.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 256 words
A shelving assembly comprising a plurality of upright posts and at least one shelf extending substantially perpendicular to said posts, each of said posts having a first upright flange and a vertically extending second flange perpendicular thereto and being provided with a waist section extending substantially perpendicular to said first flange and parallel with and extending in the same direction as the second flange having at least one lug thereon for latching said shelf to said upright posts, said shelf having a first edge part extending downward from the shelf and having recesses therein adjacent to the corners of said shelf, a second edge part positioned perpendicular to the first edge part and having a box-like profile in which the edge is bent to form an outwardly extending upper edge flange, a vertical part and an outwardly extending lower edge flange parallel to the upper edge flange, vertically aligned notches in said upper and lower edge flanges adjacent to the corner of said shelf, and when the shelf is mounted on said posts a portion of said first edge part engages said waist section and said lugs are inserted in respective recesses in said first edge part, the corners of said shelf being so shaped that when said shelf is mounted on said posts said upper and lower edge flanges abut said first flange of said post and at the same time the second flange of said post is inserted in said notches whereby the shelf and the posts supporting the shelf are rigidly connected together.
Claim 2
Dependent Claim 256 words
A shelving assembly comprising a plurality of upright posts and at least one shelf extending substantially perpendicular to said posts, each of said posts having a first upright flange and a vertically extending second flange perpendicular thereto and being provided with a waist section extending substantially perpendicular to said first flange and parallel with and extending in the same direction as the second flange having at least one lug thereon for latching said shelf to said upright posts, said shelf having a first edge part extending downward from the shelf and having recesses therein adjacent to the corners of said shelf, a second edge part positioned perpendicular to the first edge part and having a box-like profile in which the edge is bent to form an outwardly extending upper edge flange, a vertical part and an outwardly extending lower edge flange parallel to the upper edge flange, vertically aligned notches in said upper and lower edge flanges adjacent to the corner of said shelf, and when the shelf is mounted on said posts a portion of said first edge part engages said waist section and said lugs are inserted in respective recesses in said first edge part, the corners of said shelf being so shaped that when said shelf is mounted on said posts said upper and lower edge flanges abut said first flange of said post and at the same time the second flange of said post is inserted in said notches whereby the shelf and the posts supporting the shelf are rigidly connected together.
Claim 3
Dependent Claim 20 words
A shelving assembly as claimed in claim 1 wherein said box-like edge profile of said shelf is a continuous strip.
Claim 4
Dependent Claim 42 words
A shelving assembly as claimed in claim 1 wherein each of said lugs on the waist section of said post engage an adjacent recess on said first edge part, and said lug being open in the side thereof facing said first flange.
Claim 5
Dependent Claim 37 words
A shelving assembly as claimed in claim 1 wherein each post comprises two connected halves that are mirror images of each other forming a T-shaped configuration with the continuous waist section being the base of the T.
