Disclosed are support assemblies and foldable bed frames. A foldable bed frame includes a support assembly, first and second frame units, first and second holders. The first frame unit includes a first frame section pivotally connected with the support assembly and a first leg assembly pivotally connected with the first frame section. The second frame unit includes a second frame section pivotally connected with the support assembly and a second leg assembly pivotally connected with the second frame section. The first and second holders are fixedly coupled with the support assembly, and abut the first and second frame sections when the foldable bed frame is unfolded. When folded, the first and second frame sections are disposed substantially parallel to each other with the first and second leg assemblies disposed at exterior sides of the first and second frame sections.

A chest including a front panel, side panels and a top panel, the top panel including a first sub-top panel and a second sub-top panel hingably connected, a first portion of the front panel being hingably connected to a base of the chest, and a second portion of the front panel hingably connected to the first portion of the front panel and fixed to first sub-side panels, wherein the second portion of the front panel is stored when the chest is in an closed position, the first portion and the second portion of the front panel form a portion of a sleeping platform when the chest is in an open position, and the first sub-top panel is foldable onto the second sub-top panel to reduce a width the top panel extends at least during a transition between the open position and the closed position.

A sliding mattress accessory is used with an existing mattress support system coupled to an RV slide-out. The accessory includes a secondary with a fixed head section and a long deck section coupled with a hinge. The system also includes two long sliding rails longitudinally aligned and mounted to the bottom surface of the secondary deck and the top surface of the primary deck used with the existing mattress support system. The system also includes at least one support mounted on the top surface of the primary deck that supports the fixed head section. The two sliding rails and the fixed support are the same height so that the entire secondary deck is elevated approximately 3 inches above the primary deck. A lock mechanism is provided to prevent the secondary deck from moving longitudinally over the primary deck. When assembled, the secondary platform is aligned and registered over the primary deck, and a mattress is placed over the secondary deck.

The present invention provides a collapsible bed frame and a collapsible bed. The collapsible bed frame includes two side bed frames and a plurality of transverse boards, and the plurality of transverse boards are spaced between the two side bed frames. Each side bed frame includes a plurality of collapsible units, hinged to the transverse boards through first hinge elements, and a second hinge element is provided in a middle portion of each collapsible unit, so that the collapsible bed frame is transformable between an expanded state and a collapsed state. Each collapsible unit includes a first side plate and a second side plate. A front surface of the first side plate or the second side plate includes at least a first region and a second region, and the first region protrudes outward relative to the second region. According to the collapsible bed provided in the present invention, the first region on the first side plate or the second side plate protrudes outward relative to the second region. In this way, the stability of the collapsible bed frame in the expanded state can be enhanced.

A ready to assemble (RTA) bed structural system is disclosed wherein the structural system is adapted to be shipped in easy-to-assemble pieces which render the bed easier to form into a package in view of the fact that the longitudinal frame members of the bed frame can be folded in half such that the resulting package has half the longitudinal length of the ultimately assembled bed. In addition, several of the deck components of the bed can be folded together so as to effectively define an interior compartment within which other components of the bed can be housed. This effectively provides the package with a more compact footprint rendering the same easier and less costly to transport.

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.

The present disclosure discloses a foldable bed comprising 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.

A bed structure includes a bedstead formed by bedstead units. The bedstead units are symmetrically arranged with respect to the central axis of the bedstead. The bedstead unit includes a first bedstead unit and a second bedstead unit. The first bedstead unit is hinged to the second bedstead unit. A motor is provided between the first bedstead unit and the second bedstead unit. The bedstead units at both sides of the central axis of the bedstead are hinged by a fixing rod. Each of two ends of the fixing rod is provided with a clamping member. The bedstead unit is provided with a matching member connected to the clamping member. The clamping member and the matching member are hinged by a fastener. In this arrangement, the electric bed can be folded.
