Disclosed are connectors and collapsible bed frames. A collapsible bed frame includes lateral and longitudinal bar units. Between each of two adjacent lateral bar units, a first longitudinal bar unit is disposed at a first side of the collapsible bed frame and a second longitudinal bar unit is disposed at a second side of the collapsible bed frame. The first and second longitudinal bar units and the two adjacent lateral bar units are rotatably connected with each other by connectors that enable the collapsible bed frame to contract and expand while the lateral and longitudinal bar units are connected with each other.

A flexible article is provided having a core formed from a plurality of laminar panels that are inter-connected to provide an expandable structure upon movement of the panels away from each other. Opposite ends of the core terminate in a pair of end panels whereby the end panels may be moved apart to expand the expandable structure. Each of the panels are made from wood material. The panels, for example, include two wood sheets with longitudinally oriented grains and a flexible backing sheet that is sandwiched and adhered between the two wood sheets.

A sliding lounger comprises a seating portion having seating slats and seating spaces between the seating slats, a back support portion having back slats and back spaces between the back slats, the back slats being receivable within the seating spaces and the seating slats being receivable within the back spaces, and a foot support portion having foot slats and foot spaces between the foot slats, the foot slats being receivable within the seating spaces, and the seating slats being receivable within the foot spaces. The back portion and foot support portion move between an open position where the back and foot slats are not received within the seating spaces and a compact position where the back and foot slats are received within the seating spaces.

An one-piece corner connector for connecting two frame bars at right angles to one another includes a right-angle bracket having two angle legs, an intermediate plate, and two U-profile connecting pieces at right angles, having a middle leg and two side legs for insertion into the plug-in openings in the frame bars which are open at one end. The middle legs of the U-profile connecting pieces are formed on and run with their outer side parallel to the intermediate plate. The one outer side legs of the U-profile connecting pieces are each formed on one of the angle legs and run with their outer side parallel to the outer side of the angle leg. The other inner side legs of the U-profile connecting pieces are connected to one another by means of a wall element which is angled from the intermediate plate.

An adjustable bed base may be folded in half for shipping without removing the leg assemblies. The leg assemblies are adjustable in length and may be secured in a raised position to facilitate folding the adjustable bed base. To change the length of the leg assembly, a hollow leg is moved inside a hollow receiver and fixed in place by a first push pin assembly. A second push pin assembly inside the hollow receiver fixes the leg assembly in a lowered position and a raised position for storage or shipment. Each hollow receiver is pivotally secured to a mounting bracket welded to a foldable frame of the adjustable bed base.

A collapsible folding box spring assembly comprising a first subassembly that includes top and bottom frame portions; a second subassembly that includes a top and bottom frame portions; first and second T-brackets positioned between the first and second subassemblies in a hinged configuration, wherein the top frame portion of the first subassembly and the top frame portion of the second subassembly are both attached to the T-brackets at a first axis, wherein the bottom frame portion of the subassembly is attached to the T-brackets at a second axis; and wherein the bottom frame portion of the second subassembly is attached to the T-brackets at a third axis; and a plurality of rotating Z-links located between the top and bottom frame portions of the first and second subassemblies for expanding the frame portions when in an open configuration, and collapsing the frame portions when in a closed configuration.

A foldable bed comprises a bed surface unit, one or more first support legs, a first linkage bar, and a second linkage bar. A four-bar linkage is defined by the bed surface unit, the one or more first support legs, the first linkage bar, and the second linkage bar, and the four-bar linkage is configured to be changed to be alternatively in a folded state or a supporting state. A first triangular support structure is defined by the first linkage bar, the bed surface unit, and the one or more first support legs, and a second triangular support structure is defined by the second linkage bar, the bed surface unit, and the one or more first support legs.
