A foldable travel bed assembly for a vehicle provides a foldable platform that removably fits into a rear end of a vehicle to support a sleeper and create storage space. The platform has a forward section and a rearward section that hingedly connect at a horizontal fold line. The forward section folds back onto the rearward section to enable use of a middle seat in vehicle. A set of slidable support struts extends across the horizontal fold line between the forward section and rearward section. At least one handle controls the slidable support struts to be manually extended across the fold to lock the platform into operation. The platform also has a top side and a bottom side. The assembly also provides a set of height adjustable legs supporting the platform. The set of height adjustable legs hingedly collapse to lay parallel with the bottom side of the platform.

A collapsible bed frame includes a plurality of lateral bar units, a plurality of first longitudinal bar units, and a plurality of second longitudinal bar units. The plurality of lateral bar units includes first and second outer lateral bar units and at least one inner lateral bar unit. A collapsible bed frame also includes a plurality of first connectors, each having a body and a supporting piece. The body is fixedly connected with an end of the first or second outer lateral bar unit, and the supporting piece is rotatably connected with an adjacent first or second longitudinal bar unit. The collapsible bed frame can contract and expand while the lateral and longitudinal bar units are connected with each other.

Disclosed are adjustable supports and foldable bed frames. An adjustable support includes inner and outer tubular bars movably coupled to each other. A locking mechanism is disposed in the inner tubular bar and includes a positioning piece to restrict the inner and outer tubular bars from moving with respect to each other. An unlocking mechanism is fixedly coupled to the outer tubular bar and includes a push button to unlock the locking mechanism.

Systems and methods for use of a rollaway folding bed system are described. The rollaway folding bed system can include a mattress and a frame configured to be moveable between a deployed state and a stored state. The rollaway folding bed can include a rigid frame and sections of support grid affixed to the bars to provide support to the mattress. The rigid frame can also have moveable supports that can moved between a folded position and a stored position. The rigid frame can include central supports having hinges to facilitate moving the rollaway folding bed from a stored position and a deployed position. The crossbars can include lockable wheels affixed at opposing ends of the cross bars and positioned beyond an outer edge of the rollaway folding bed system when in a stored position to provide stability to the rollaway folding bed system.

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.

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.

A foldable bed includes a first bed unit, a second bed unit rotatably connected to the first bed unit such that the bed is rotatable between a folded state and an unfolded state, and a stop unit arranged between the first bed unit and the second bed unit for preventing the first bed unit and the second bed unit from rotating relative to each other when the bed is at the unfolded state. The first bed unit includes a first support bracket and a first platform part supported on the first support bracket. The second bed unit includes a second support bracket and a second platform section supported on the second support bracket. When the bed is at the unfolded state the second platform section and the first platform section cooperatively form a platform of the bed for supporting a load.

A collapsible bed frame includes a first lateral bar unit, a second lateral bar unit, and a longitudinal supporting bar unit. The first and second lateral bar units are disposed substantially parallel to each other. The first lateral bar unit includes a first coupler to removably couple with a first end of the longitudinal supporting bar unit. The second lateral bar unit includes a second coupler to removably couple with a second end of the longitudinal supporting bar unit. The collapsible bed frame also includes first and second longitudinal bar units. The first longitudinal bar unit is rotatably connected with the first ends of the first and second lateral bar units. The second longitudinal bar unit is rotatably connected with the second ends of the first and second lateral bar units.
