A modular shelving unit includes a base plate that is planar in an expanded configuration. A first foldable wall is connected to a first side of the base plate. A second foldable wall is connected to a second side of the base plate. The first foldable wall has a first segment and a second segment, and the second foldable wall has a third segment and a fourth segment. The second and fourth segments are rotatable about a respective hinge to define an interior surface with its respective first or third segment when in the expanded configuration. Shelves extend from the interior surfaces in the expanded configuration. In the collapsed configuration, the second and fourth segments are rotated about their respective hinges out of planar with their respective first and third segments. Other embodiments of modular shelving units are described herein.

A modular locker comprising at least two vertical towers being positioned side by side. Each vertical tower defines a front opening and a space therein and comprises spaced apart lateral walls interconnected by top, bottom, and rear parts. The lateral walls define respective inner and outer sides. The outer side comprises a protruding contour surrounding a recessed surface. The interfacing lateral walls of adjacent vertical towers are releasably connected defining an enclosure therebetween. A plurality of compartments for containing parcels therein are vertically arranged within each of the towers. Each of the compartments comprises a shelf structure comprising a shelf floor and a door. The shelf floor is mounted to the inner sides of the spaced apart lateral walls. The door is mounted to the tower at the front opening and is movable between open and closed positions thereby providing for selectively accessing the compartment.

Modular shelving comprising at least one shelf supported by at least one tube, wherein said shelf is coupled to said tube by means of a coupling element which is arranged externally in said tube and internally in a hole passing through the shelf, where each coupling element is divided lengthwise into two identical halves which are tongue and groove coupled together and, being coupled, can fit snugly into the hole of the shelf, whereby a tube supporting the shelf is fitted.

A method for building large-scale play structures having an ideal modularity is provided. The method includes providing panels having a thickness, a planar-quadrangle shape including a length, a width and four chamfered edges with a set of holes located along each edge, the holes located at a fixed interval relative to one another, the fixed interval providing a unit of length, a fixed-location fastening element located in each of the holes, respectively; providing a plurality of movable fastening elements each including a hand-grip to allow the respective movable fastening element to be moved between an unsecured position and a secured position without the use of tools when received by any one of the plurality of fixed-location fastening elements; and employing the fasteners to secure a plurality of the panels to one another to provide a structure that has an overall height, an overall length and an overall width, the structure including at least a pair of panels oriented one above the other and at least a pair of panels located at the same elevation and secured at right angles to one another.

What is disclosed is an assembly system to create customizable, mobile, lightweight containers and container-like products ranging in size from consumer and commercial storage products to shipping containers and small mobile buildings. The system uses slidable interconnection of various profile shapes of elongated panel modules with same length standardized linear and corner panel connectors, to create container sleeves retained by customizable end framing to become container shells. The container shells are customized to size needed by the number of interconnected panel modules used and the length to which they are cut. Assembly of their few basic parts is simple with a limited range of tools and skills needed. The system further provides for simple, seamless, solid and reversible structural attachment of third party components, without welding or riveting, to achieve specific customization goals as needed. Finally, the system provides for easy and scar free disassembly for shipping, storage reconfiguration, or recycling.

A tube joint structure for industrial-style furniture rack includes a tube body. The tube body is assembled by two or more half-configured housings including a first housing and a second housing. The first housing and the second housing are respectively formed by stamping two metal pieces. Two recessed portions are formed on opposite sides of the first housing and the second housing, respectively. The recessed portion of the first housing and the recessed portion of the second housing enclose an accommodating space. The tube body has at least two tube openings communicating with the accommodating space.

A modular display unit. The modular display unit includes a core shelving element or elements and a variety of end caps. To achieve a desired shelving configuration desired end caps are selected, and the core shelving units are attached to the end caps. In alternative examples a customer may go on line and order a custom made shelving unit by specifying a configuration, cut-out design, graphic design, and surface finish. The modular display units are easily shipped as flat sheets that may be assembled by the end user. The products are eco-friendly, and may be easily recycled as they are made of paper fiber products.

A modular cabinet assembly has at least a first sub-cabinet and a second sub-cabinet. Each sub-cabinet includes a back board having at least two separate back board pieces that are pivotably connected to each other, a left side board pivotably connected to one of the at least two back board pieces, and a right side board pivotably connected to another of the at least two back board pieces. At least one shelf board having opposite ends is removably connected to the left side board and the right side board of either the first sub-cabinet or the second sub-cabinet. A first end board is connected to either an upper end of the first sub-cabinet or a lower end of the second sub-cabinet. A first connector removably connects the left side boards of the first and second sub-cabinets, and a second connector removably connects the right side boards of the first and second sub-cabinets.

A support connector is provided and includes a support body and a latch. The support body includes a latch receiving passageway extending from a first end thereof and into interior of the support body. The latch extends into the latch receiving passageway and is secured to the support body. The latch includes a latch body, a lever, a latch pin and an expanding element. The latch body includes a body base and a lever receiving space extending through a center thereof. The lever is secured in the lever receiving space and is rotatably connected to the latch body. The latch pin extends through the body base and is connected to the lever, while the expanding element is positioned between an end of the latch pin and the body base. The expanding element receives the latch pin.

Provided is a technique to make it easy to carry out alignment in connecting a plurality of shelf units. An assembly shelf is configured by stacking a second shelf unit on a first shelf unit. An upper surface of at least one first horizontal frame member which is disposed in an upper part of the first shelf unit and a lower surface of at least one second horizontal frame member which is disposed in a lower part of the second shelf unit are respectively provided with engagement structures that engage with each other.
