A collapsible furniture item having a set of panels that a person without the aid of tools can slidingly interlock with each other to form a standalone upright furniture item and once assembled can be quickly disassembled also without the aid tools to allow the panels to be transported to a different location for quick and efficient assembled into a standalone upright furniture through interlocking engagement between the panels.

A portable table (1), comprising a table top (11) and a frame (1a) having two front legs (2, 3) and two rear legs (4, 5) as well as two front arms (6, 7) and two rear arms (8, 9). The front arms and front legs are fastened on a first, front connecting element (12), and the rear arms and rear legs are fastened on a second, rear connecting element (13). The first, front connecting element is connected to the second, rear connecting element by at least one first connecting rod (14). Coupling elements connecting the arms to in each case one first or second longitudinal rod (54, 55), are arranged on the upper ends of the arms. The table top comprises at least one device (65a, 65b, 66a, 66b) by means of which the table top is releasably fastenable on the frame.

A stackable wooden crate that can be assembled and disassembled without tools, and stored flat is provided. The crate may include: two sides with box joint tabs, two sides with matching box joint recesses, a bottom, and a lid. The sides may come together at box joints held together with strap binding that stretches tight when the sides are folded 90 degrees to each other. A modified strap binding on one corner of the box is held tight via a tensioner buckle. The bottom is held captive by the four sides. The lid rests between four tabs that extend upward out of all four sides. When the lid is removed, multiple crates can be stacked, the upper crate held in place by the lower crate's four tabs which interface with recesses on the bottom of the upper crate.

A tension-compression base structure including tension elements (such as flexible cables or ropes) and compression elements (such as rigid legs) is provided with a slidably adjustable path for the tension elements around or within the compression elements, thereby enabling a degree of adaptability to support surfaces that may not be ideally flat, such as on outdoor terrain. Such a tension-compression base may be used to support a platform, a stool, or an item of equipment that may be desirably held in a preferred orientation irrespective of terrain irregularities, and as furniture may be configured to rock with a user's body as a form of active seating.

A display case has a first display case portion with walls configured so that each wall of a plurality of first fixed walls has a coupling edge arranged at the same coupling framework between the first portion and a second portion of the display case. The coupling edges of the first fixed walls are coplanar to one another and at least two of the first fixed walls are adjacent to each other and fastened together through gluing along a corner substantially perpendicular to the plane of the coupling edges. A groove is formed longitudinally on the coupling edge of each of the first fixed walls, the grooves of the first fixed walls jointly defining a channel along the coupling framework; a hoop cable is housed in the channel, closed on itself. The hoop cable contributes to keeping the walls coupled together at the coupling framework, ensuring that the walls stay in position even in the case in which the gluing with which the first fixed walls are fastened together partially or even totally gives way.

A leg assembly includes four legs, each of the legs configured to couple to an outer edge of a generally planar member to form an assembly that has a surface supported by the four legs. The leg assembly also includes an adjustable strap coupled to and extending between two of the four legs to form a bracing structure to provide enhanced structural rigidity for the assembly for attachment to a planar element includes four legs.

A calculus structure has a plurality of unit components and a plurality of joint components is provided. The unit components and the joint components are adapted to form a target structure. Each end of each of the joint components has an embedding construction or an embedded construction. Each of the unit components and the joint components has a bore therein for communication with each other. The bore is adapted to allow a cascading part to pass therethrough so that the unit components and the joint components are cascaded together by the cascading part, and the unit components and the joint components are movable relative to the cascading part so that the unit components and the joint components abut against each other in a cascading order to form the target structure.

A stackable wooden crate that can be assembled and disassembled without tools, and stored flat is provided. The crate may include: two sides with box joint tabs, two sides with matching box joint recesses, a bottom, and a lid. The sides may come together at box joints held together with strap binding that stretches tight when the sides are folded 90 degrees to each other. A modified strap binding on one corner of the box is held tight via a tensioner buckle. The bottom is held captive by the four sides. The lid rests between four tabs that extend upward out of all four sides. When the lid is removed, multiple crates can be stacked, the upper crate held in place by the lower crate's four tabs which interface with recesses on the bottom of the upper crate
