A double bunk bed loft system having a staircase and landing on both the lower and upper levels which create hallways between the individual bunks. The hallway allows for users to stand up, but because the placement of upper bunks is over the lower bunks above the beds, the entire bunk system is shorter and saves vertical space. To create a more spacious feel for the lower bunk, the system is designed using exposed beams to support the upper bunk. The upper level remains open to add height.

Variable planform shelving systems include a variable support platform and a support surface assembly that is supported by the variable support platform. The variable support platform includes frames that can be repositioned relative to each other to vary the planform of the variable support platform. The support surface assembly provides a support surface for supported items. The support surface assembly is flexible and/or comprised of a plurality of linked panels so that the support surface provided varies in response to variation in the planform of the variable support platform.

A post coupler has one or more positive post stops therein limiting extension of an end of a post section in or over the coupler beyond the stop. The stops may be freely extended tabs or stop embossments from or in the coupler flanges. Outside wrap, inside wrap and hidden post couplers are disclosed, as well as assembly methods.

A stackable rack includes a bottom rack frame; a top rack frame; a locking assembly that connects with the bottom rack frame and the top rack frame; wherein the bottom rack frame comprises a main supporting frame, at least one first supporting frame rotatably coupled with the main supporting frame and supported on a ground, and a second supporting frame having a securing assembly being coupled with the first supporting frame and rotatably coupled with the main supporting frame; wherein the securing assembly comprises at least one locking bracket with a locking cavity being engaged with the first supporting frame.

The invention relates to a knock down table suitable for food preparation that includes extension legs and terminal legs that are interconnected with a threaded connector and threaded receiving plugs in the connecting ends of the extension and terminal legs. One of the receiving plugs in each connection protrudes from the end of its legs and is configured to extend into the connecting leg and abut with the receiving plug in the other leg.

A shelf rack includes first and second identical shelf units each including a first frame with first and second legs having respective first and second feet, a second frame with third and fourth legs having respective third and fourth feet and at least one shelf. The second and fourth feet have an outer diameter that is less than an outer diameter of the first and third feet. The second shelf unit is inverted and the first and second frames of the first shelf unit toollessly assemble to the first and second frames, respectively, of the second shelf unit by mating the larger outer diameter feet of the first shelf unit with the smaller outer diameter feet of the second shelf unit and mating the larger outer diameter feet of the second shelf unit with the smaller outer diameter feet of the first shelf unit.

A portable structure has a main body and a plurality of telescopic beams. The main body includes a plurality of stacking modules. The plurality of stacking modules are configured to move between a collapsed position and an uncollapsed position. Each of the plurality of stacking modules has an inner surface and an outer surface. The plurality of stacking modules include a bottom stacking module and a top stacking module. The bottom stacking module is selectively and slidably disposed within the top stacking module. The top stacking module has a plurality of holes formed therethrough. The bottom stacking module is nested within the top stacking module, where the plurality of stacking modules are in the collapsed position. The bottom stacking module is unnested from the top stacking module, where the plurality of stacking modules are in the uncollapsed position.

An angle bar includes two longitudinal angled plate portions, and a corner portion connecting therebetween. The corner portion has an inner corner surface bounding an inner corner space and an outer corner surface. A stopper protrudes into the indented corner space, and has an abutment face extending across the indented corner space. A limiter protrudes into the indented corner space from the inner corner surface, and has a through hole opening in a direction along a bending line of the corner portion. A modular post assembly has at least two angle bars abutting each other, and a fixing rod extending through the through holes of the bars along the bending line and limited between the stoppers for fixing together the bars.

Provided are reinforced shelves, kits for reinforced shelves and shelving units comprising at least one reinforced shelf.
