US 4,351,244 A · Shelving system

Abstract

In a four-post merchandizer, two light-gauge sheet metal corner posts are reinforced against twisting by a dual camming action by which the two posts are urged tightly against the corners of the shelves. Each post comprises two telescoping post sections, and a unitary coilable, flexible trim sheet, received in grooves formed in the post elements, and extending from one end of the post to the other. The posts have a W-shaped horizontal cross-section, in which a pocket is formed for receiving the ends of shelf hooks, thereby protecting the flexible trim from damage. Base panels are secured together by sliding a first flange of one panel into a pocket formed by second and third flanges of another panel and two perpendicular surfaces of a post. By tapering the ends of the first and third flanges, the entry of the first flange into the pocket can be carried out without careful initial alignment. Pairs of post elements are permanently secured in parallel relationship to each other at opposite ends of base panels to provide U-shaped units to facilitate on-site assembly.

Dependent claims

A system of shelving comprising a shelf, and an upright supporting post, said shelf having a hook comprising a sheet metal projection lying in a substantially vertical plane and having a downwardly open notch, and said post comprising a sheet metal element lying in a substantially vertical plane and having a slot for receiving said hook;

in which the notch of the hook has a first oblique camming surface engageable and cooperable with an edge of the slot for urging the shelf in a first horizontal direction with respect to the post as the hook is moved downwardly with respect to the post, and in which the slot has a second oblique camming surface engageable and cooperable with an edge of the sheet metal projection of the hook for urging the shelf in a second and different horizontal direction with respect to the post, and in which the post and shelf also have mutually engageable means for limiting the relative movement of the post and shelf in both of said first and second directions, said mutually engageable means being positioned so that they first come into engagement while said edges are in engagement with intermediate portions of their cooperating camming surfaces, whereby, upon downward movement of the shelf, said mutually engageable means become tightly engaged, and the shelf and post are rigidly secured together.

In a shelving system, an upright shelf supporting post comprising first and second elongated, sheet metal post elements in telescoping relationship with each other the second element extending upwardly from the upper end of the first element, each of said elements being so formed as to provide first and second grooves extending vertically substantially the full length of the element, the first groove of the first element being substantially aligned with the first groove of the second element, and the second groove of the first element being substantially aligned with the second groove of the second element, whereby the assembled post has two grooves extending vertically substantially the full length thereof, and an elongated, flexible sheet, coilable about an axis transverse to its lengthwise direction, extending substantially the full length of the post, and having substantially parallel opposite edges extending in the lengthwise direction, said parallel opposite edges being received in and retained by the respective grooves of the post.

In a shelving system, an upright shelf supporting post element comprising web means having opposite vertical edges, and return flanges formed at said opposite vertical edges to provide first and second grooves extending vertically substantially the full length of the element, and an elongated, flexible sheet, coilable about an axis transverse to its lengthwise direction, extending substantially the full length of the element, and having substantially parallel opposite edges extending in the lengthwise direction, said parallel opposite edges being received in and retained by the respective first and second grooves;

and in which said web means comprises a pair of vertically elongated sections disposed in non-parallel vertical planes, said sections being connected together so that each section is located substantially on one side of the plane of the other section;
in which said opposite vertical edges of the web means are constituted by vertical edges of said vertically elongated sections;
in which the return flange on each vertically elongated section is located on the side thereof opposite the side on which the other vertically elongated section is located;
and having V-shaped means connected said vertically elongated sections to each other, said V-shaped means forming part of the web and being arranged so that the horizontal cross-sections of the web are W-shaped, and said V-shaped means having shelf hook-retaining slots formed therein, and providing a pocket for the ends of the hooks, thereby preventing the ends of the hooks from interfering with said coilable flexible sheet.

1 more element

In a sheet metal shelving system, a base comprising:

a first panel disposed in a vertical plane and having a vertical edge, a second panel disposed in a vertical plane perpendicular to the plane of said first panel, said first and second panels meeting each other at a corner of said base, means on said first panel providing a first flange extending generally perpendicularly from said vertical edge, means on said second panel providing a second flange extending generally pependicularly from said second panel and parallel to said first panel, and a third flange extending from said second flange and forming an acute angle therewith, said third flange extending toward the corner formed by said first panel and said first flange, and means rigidly secured to said second panel and providing a first surface generally perpendicular to said second flange and a second surface spaced from and generally parallel to said second flange, and in which said first panel is disposed against said second surface, said first flange is disposed against said first surface, and in which the outer edge of the third flange bears against the corner formed by said first panel and said first flange and holds said first panel in engagement with said second surface and holds said first flange against said first surface.
