A modular frame assembly is disclosed. The assembly includes a plurality of supports, and at least one connector for interconnecting the supports. The connector includes a base, a plurality of legs extending outwardly from the base, each leg defining a socket having an exterior surface that has a generally constant profile throughout the length of the leg, and a member that is movable between an engaged position in which it projects interiorly of the leg, and a disengaged position in which it is flush with the exterior surface, the member being biased to the disengaged position. Additional components, such as shelf supports, mounting brackets, shelf brackets, and risers, can be included in the assembly. The modular nature of the assembly allows for a wide arrangement of structures to be created.

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.

In a skeleton frame of a storage box, a boundary frame, front columns, and rear columns are integrally formed. Therefore, the ease of assembly of the storage box can be improved. In addition, gouged portions that are depressed inward in a width direction from an outermost shape in the width direction of the boundary frame are formed in both side portions in the width direction of the boundary frame. When the skeleton frames are nested, the front columns of the skeleton frame on a lower side are disposed in the gouged portions of the skeleton frame on an upper side. Accordingly, even in the skeleton frame where the rear columns and the front columns are integrally formed with the boundary frame, the skeleton frames can be nested in a vertically stacked state.

A device for connecting modular metal shelving units, comprising at least two props (1) and at least one connecting element (2), for mutual coupling of the two props (1). Each prop (1) comprises central couplings (14), first distal couplings (16) and second distal couplings (17), and each of the couplings (14,16,17) comprises a central coupling (11) and a first adjustment slot (12). The connecting element (2) comprises a first grouping (21) of pins (20), which can be inserted into the first distal couplings (16) of a prop (1), and a second grouping (22) of pins (20), which can be inserted into the second distal couplings (17) of another prop (1). The first adjustment slot (12) of the first distal couplings (16) is diametrically opposed to the first adjustment slots (12) of the central couplings (14) and the second distal couplings (17).

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.

A modular storage system having a frame system, a rod attachment system, and one or more shelves or storage containers. The rod attachment system comprises a rod, a connector, and a fastener. The connector may be secured around a support rod of the frame system and the fastener may extend through the connector and secure the rod to the frame system. The rod may also be secured in a wall mount. The frame system may have a plurality of shelf openings and the shelves or storage containers may be interchangeably disposed in the shelf openings. The storage containers may have an end wall which is substantially the height of the shelf opening and an end wall which is less than the height of the shelf opening. The storage container may be disposed in the shelf opening with either end wall facing out of the shelf opening.

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.

Various embodiments of the present invention are directed to an apparatus comprising a heavy duty shelving assembly. The apparatus comprises shelving assemblies that may be used to store relatively heavy objects such as vehicle components, athletic weights, or the like. The apparatus comprises a plurality of vertical columns including column members that are selectively coupled to one another, a plurality of horizontal supports that extend between the column members, and a plurality of shelves that are positioned on the horizontal supports. The apparatus may also include a center brace extending between opposing horizontal supports. The horizontal supports include a truss portion connected to a support portion; the truss portion distributes the downward forces applied to the support portion by the shelves. The design of the apparatus and the truss increases the downward forces that may be applied to the shelf, thereby increasing the weight capacity of the shelves and the apparatus. The column members are configured for selective coupling by incorporating a main portion that comprises a plurality of apertures and a coupling portion that extends outward from the main portion such that it may accept at least part of a main portion of an adjacent column member. The coupling portion further comprises one or more engagement tabs that are configured to engage the apertures of an adjacent column member. In at least one embodiment, the engagement tabs are formed through stamping, thereby minimizing or entirely eliminating areas where stress can concentrate when the apparatus is under load. This feature reduces or eliminates the potential of a partial failure when the apparatus is under load.

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.

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.
