An improved sleeve for a shelving unit having an annular collar wedge the sleeve against a post, wherein the sleeve has one of a retaining wall encircling the bottom of the sleeve or a retaining latch extending from a bottom of the sleeve, both to position and retain the collar during assembly and to support the collar during use.

A shelving system (10) comprising a plurality of tubular posts (12) and a plurality of rail segments (72) securable parallel to the posts (14). Each of the rail segments (72) comprises an elongate member having a U-shaped cross section such that the rail segment includes a central wall (74) and first and second side walls (76, 77) such that the posts (12) are received between the first and second side walls (76, 77) and wherein the rail segments (72) include apertures (46) along the lengths thereof to receive tracks (48) for supporting drawers (51).

An equipment rack, mounting rails for the equipment rack, and associated methods. The mounting rails are selectively movable on a frame of the equipment rack and can be clamped to secure the mounting rails to the frame. A clamp of the mounting rail can include a clamp arm having a clamped position and an unclamped position and a lever arm for moving the clamp arm between the clamped and unclamped positions.

A folding shelf apparatus is provided. The folding shelf includes forward vertical supports and rearward vertical supports. At least one horizontal shelf is pivotally mounted to the forward supports and the vertical supports so that the shelf of the present invention may fold. The present invention further includes at least one wall mount that is attachable to a wall, and at least one latch protruding from the folding shelf and releasably attachable to the wall mount.

A storage unit comprising a frame portion and a liner portion. The frame portion is comprised of vertical supports that engage and support the liner portion. The liner portion included a backer portion. The liner portion also comprises angled shelving components that extend from the front and back of the liner portion, with the shelving components attaching to the backer portion and the frame.

A spliced storage box and a splicing structure between adjacent side panels of the spliced storage box are provided. The splicing structure comprises two side panels, a post, and a pressing strip. A side of the post comprises a notch, each corner of two sides of the notch comprises a first positioning edge and a second positioning edge intersecting the first positioning edge. Side edges, which are adjacent to each other, of the two side panels each bend and define a first abutting edge and a second abutting edge. The first abutting edge is disposed at an outer end of a respective one of the two side panels, and the first abutting edge and the second abutting edge respectively abut the first positioning edge and the second positioning edge. The pressing strip is connected to the post and is pressed to the first abutting edges of the two side panels.

A middle shelf installation tool is disclosed for use in combination with a pair of upstanding corner posts during the assembly of a boltless shelving system. Upper and lower sets of hingedly connected corner post surrounding members are spaced one above the other so as to extend across the top and bottom of the installation tool. The installation tool is wrapped in surrounding engagement around the bottom of an upper one of the pair of corner posts and the top of the lower one of the pair. The installation tool forms a splice to hold the upper and lower corner posts in axial alignment one above the other to facilitate the location by a single individual of a middle shelf at the intersection between the corner posts to lie between upper and lower shelves of the system. Once the middle shelf has been installed, the installation tool is pulled off and removed from the corner posts.

A present application is directed to a shelving system having a coupling system comprising a tab coupler and a socket coupler, said tab coupler comprising a locking tab extending from a locking face along a locking axis and configured with a round, T-like sectioned shape; said socket coupler comprising a U-shaped locking socket projecting from a mounting face of the socket coupler along a coupler axis and configured with a U-shaped tab arresting groove; the coupling system is configurable between an unlocked position whereat the locking socket slidingly receives the locking tab so that the locking axis and the coupler axis coincide, and a locked position upon rotating one of the tab coupler and the socket coupler about the coinciding axes, entailing snugly arresting of the locking tab by the locking socket, preventing sliding displacement and axial displacement along the coinciding axes.

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 invention provides a combining and expanding structure of a layered frame, especially to provide a design of a combining hook of a layer plate of the layered frame for allowing the layered frame to be easily combined in a coupled or multiplied format; a combining part of the combining hook is designed to be formed in various structural statuses with respect to the layer plate made of different materials and formed in different statuses, so that the combining hook is able to be respectively combined at four distal corner parts of a metal-state layer plate, an iron-rod layer plate, a wooden-state layer plate or a glass-state layer plate, a buckling hook part of the combining hook is designed in a half-thickness status, so that the combining hooks disposed at the left and the right distal corner parts of the layer plate are able to be oppositely arranged.
