A shelf support beam (80, 130, 200) for use in a shelving unit (10) to support a shelf (22). A structural member (82, 132, 202) has a C-shaped cross-section. A web (94, 144, 216) separates a top flange (96, 146, 220) from a bottom flange (112, 162, 234). The top flange (96, 146, 220) is configured to support the shelf (22). The web (94, 144, 216), the top flange (96, 146, 220), and the bottom flange (112, 162, 234) define a channel (92, 142, 214) of the member (82, 132, 202). The channel (92, 142, 214) defines a cavity height (C1, D1, E1). The top flange (96, 146, 220) and the bottom flange (112, 162, 234) define a top flange width (C2, D2, E2) and a bottom flange width (C3, D3, E3), respectively. A ratio of the cavity height (C1, D1, E1) to a sum of the top flange width (C2, D2, E2) and the bottom flange width (C3, D3, E3) is greater than 1, is at least 1.20, or is about 1.40. The C-shaped cross-section has a moment of inertia (98, 148, 238) of greater than 0.40, greater than 0.45, or at least 0.46. The top flange (96, 146, 220) includes an elevated portion (100, 150, 222) and a lower or shelf support portion (104, 154, 226) separated by a sidewall (106, 156, 230).

The present invention discloses a shelf comprising a plurality of cross beams, a plurality of support portions and at least one rest portion. Each of the cross beams is connected to a corresponding support portion by a connector, and a side face of each of the cross beams has a rest face for placement of a corresponding rest portion. At least two opposite ends of the rest portion are arranged on the rest faces, in the same plane, of at least two corresponding cross beams. The plurality of cross beams and the plurality of support portions are profiles formed by die extrusion-stretching. Compared with a traditional shelf, the shelf according to the present invention has the advantages of light weight, having less tendency to rust and corrode, being easy to disassemble and assemble, being free of stress concentration problem, and the like.

The present application discloses a collapsible organizer of the present application comprises a base, a pair of side walls and a pair of top rods. The pair of side walls is rotatably coupled to the base, wherein each of the side walls comprises a pair of slots. Each of the top rods comprises a straight portion and a pair of insertions coupled to two ends of the straight portion correspondingly, one of the insertions is insertably coupled to one of the slots of one of the side walls, another one of the insertions is insertably coupled to one of the slots of another one of the side walls. A method for utilizing the aforementioned collapsible organizer is also disclosed, comprising: rotating the pair of the side walls; and inserting the pair of top rods to the slots of the pair of side walls.

A system of racks comprising of at least two racks that can be nested together when they are not in use thereby minimizing the space required for their collective storage. Each rack is comprised of a frame having two or more frame elements linked together by at least one Z-shaped bracket. Each frame element is comprised of two vertical support members linked by a plurality of tray holders at spaced apart distances along the interior side(s) of the vertical support members. The plurality of tray holders on each of the frame elements linked by a Z-shaped bracket are substantially aligned in the vertical direction thereby forming a set of pairs of tray holders. Each pair of tray holders is configured to receive and support the placement of trays. The trays comprise of a flat base portion with upstanding side edges which may be welded to a wire element to reduce crevices where debris and contaminants may otherwise be trapped and to assist with cleaning of the trays. When the racks are not in use, the trays are removed allowing the racks to nest together along their Z-shaped bracket.

A mobile wall comprising an alignment pin moveably supported on a crossbar adjacent a vertical support. The alignment pin is selectively moveable between a retracted position, in which the alignment pin is retracted into a first aperture, and an extended position, in which at least a portion of the alignment pin extends outwardly from the first aperture. The alignment pin is selectively receivable in an aperture of another mobile wall while in the extended position to align the mobile wall with the another mobile wall.

An elastic strap anchor assembly 240 including hook portion 250 and cover portion 260. Hook portion 250 includes a plurality of hooks, such as hooks 251A, 251B, 251C, 251D, a plurality of flexing holes, such as flexing holes 252A, 252B, a plurality of clips, such as clips 253A, 253B, a plurality of guide posts, such as guide posts 254A, 254B, and tab portion 255. Cover portion 260 includes a plurality of clip portions, such as clip portions 263A, 263B, a plurality of elastic grips, such as elastic grips 264A, 264B, 264C, a plurality of rigid grips or pins, such as rigid grips 265A, 265B, and a plurality of guide holes, such as guide holes 266A, 266B.

Each of the support shafts defines a plurality of notches configured for suspending a horizontal bar from the support shafts. Top ends of the support shafts of one pod are configured to support a platform of another pod thereon.

The present invention is directed to a method of forming a container comprising forming a basket portion of metal mesh material and a rail connected to the basket portion. The rail extends substantially outwardly from the outer surface of the basket portion and the rail extends continuously around the outer surface of the basket portion. In one example, the method includes forming the rail so that it does not contain or surround a free edge of the basket portion. In another example, the method includes forming the rail so that it includes an opening for containing or surrounding a free edge of the basket portion. The method may also include forming a lower rail. The present invention is also directed to a container formed by such method.
