The present subject matter discloses a board coupling structure with a first board and a second board. The first board and the second board are respectively formed with strip-shaped ribs and strip-shaped grooves that can be interlocked with each other. The first board and the second board can only move relative to each other in the inserting direction. The strip-shaped rib can comprise a longitudinally extending arm and an inclined or a curved arm. In particular, the strip-shaped rib can increase the contact surface of the strip-shaped rib and the strip-shaped groove. Moreover, the connected boards do not need connectors. In addition, the board coupling structure can have a wide range of applications with a particular use in connecting two adjacent boards of a box.

Described herein are systems, modes, and methods for mounting one or more electronic housings to each other and to a rack mount system, a table mount system, or wall mount system. The mounting system includes a first pair of matching sliding panels that interface with each other in a slidingly engaging manner. Each of the first pair of sliding panels can be mounted to housings prior to being engaged with each other; the engagement of the first pair of sliding panels removably fixes the two housings together; additional housings can be fixed to the first two in a substantially similar manner. The first pair of sliding panels includes a U-shaped sliding panel and a C-shaped sliding panel, and according to a second embodiment, a second pair of sliding panels includes a C-shaped sliding panel and a Pi-shaped sliding panel. The second pair of sliding panels operates in a substantially similar manner as the first pair of sliding panels.

A joining device for parts of furniture and furnishing accessories, including a casing or container body suitable for being inserted in a seat formed in one of the components of the item of furniture to be joined and provided with an expansion bushing externally projecting with respect to an open end of the casing or container body and suitable for engaging with a further seat of a further component of the item of furniture to be joined to the component wherein the casing or container body is inserted, the joining device which includes a cam mechanism for a linear and reciprocated motion of an actuation unit co-operating in an expansion deformation movement of the expansion bushing and in a backward and traction movement of the same expansion bushing, with the cam mechanism and the actuation unit housed in the casing or container body and actuated by a tool.

A set of panels including a panel with a first main plane and an adjacent panel with a second main plane, wherein the panel and the adjacent panel are provided with an angleable locking device for locking a first edge of the panel to a second edge of the adjacent panel. The first main plane is essentially perpendicular to the second main plane. The angleable locking device includes an edge groove at the first edge and a tongue groove at the second edge. The edge groove includes a flexible tongue arranged in an insertion groove at a first side of the edge groove. The angleable locking device is configured to be unlocked by an angling motion of the panel relative the adjacent panel, such that an angle between the first and the second main plane increases.

A blow-molded plastic structure, such as a tabletop, may include an undercut. For example, the tabletop may include a frame receiving portion and a frame connecting structure with an undercut may be disposed in the frame receiving portion. A portion of the frame may contact or engage the frame connecting structure, such as the undercut, when the frame is connected to the tabletop. In an exemplary embodiment, a first side of the frame receiving portion may include a first frame connecting portion with an undercut and a second side of the frame receiving portion may include a second frame connecting portion with an undercut. The first frame connecting portion with an undercut may be disposed on an opposing surface from the second frame connecting portion with an undercut.

A removable door bin height extender for a refrigerator door bin of a refrigerator, including: a frame having a front retaining portion that extends to a right side retaining portion and a left side retaining portion; and a pair of spaced apart, plate-shaped gripping fingers that extend downward from a bottom portion of each of the right side retaining portion and left side retaining portion. The pair of spaced apart, plate-shaped gripping fingers on the right side retaining portion and on left side retaining portion of the frame are configured to slide over and grip a right side wall and a left side wall, respectively, of the refrigerator door bin.

A compartment divider assembly. The compartment divider assembly may comprise: one or more dividers and at least one coupler. The one or more dividers may comprise a first divider and a second divider. The at least one coupler may comprise at least one support coupler and at least one set of prongs. The one or more dividers may further comprise at least one dovetail groove traversing along a longitudinal axis. The one or more dividers may be positioned substantially horizontally. The first divider may be positioned substantially perpendicular to the second divider. The at least one set of prongs may further comprise at least one planar face and at least one non-planar face. The at least one non-planar face of the at least one set of prongs may be adapted to engage with at least one dovetail groove of the one or more dividers.

A retaining system for joints without utilising welds, screws or any other additional element or accessory, consisting in the making of a closing or locking mechanism, by means of a tab-slot configuration, using only the structure proper of the sections which are the object of the jointing, according to a first section (A) on which the cutting or machining that gives rise to the tabs and an embedment gap is made and a second section (B) that houses the slots and has to fit in the said embedment gap of section (A). Finally, the system is supplemented with the addition of tools that make it possible to release the system, thus making the joint demountable.

A bed can include one or more connectors for connecting components of the bed. For example, a frame can include a fastening mechanism for releasably connecting a cross-member to a longitudinal support. Another example includes connectors for connecting and aligning a foundation with a frame.

Provided is prefabricated furniture and, more particularly, to a prefabricated shelf (angle) having assembly holes and assembly protrusions for assembling frames together, the frames being more firmly assembled as a pressing protrusion portion protrudes from a narrow portion of an assembly hole so that an assembly protrusion is forcibly fitted by the pressing protrusion part. The prefabricated shelf includes a first frame in which a pair of assembly holes, each having a wide portion and a narrow portion, are arranged symmetrically, and a second frame in which a pair of assembly protrusions, corresponding to the assembly holes and each protruding to fit into the narrow portion, are arranged symmetrically, wherein the narrow portion includes a pressing protrusion portion configured to protrude from a first end thereof and press the assembly protrusion to a second side thereof to force the assembly protrusion into place.
