An outdoor appliance has a support frame with multiple inner lining tubes that are sequentially connected end to end by flexible ropes and multiple outer sleeve tubes that are slidable on the outer surfaces of the inner lining tubes. The outer sleeve tube and the inner lining tube at the head end of the support frame are respectively connected to an elastic member. When the support frame is in a locked state, each inner lining tube is located between and supports two abutting adjacent outer sleeve tubes. When the support frame is in an unlocked state, each inner lining tube is moved out of one outer sleeve tube and into the next successively axially adjacent outer sleeve tube against the force of the elastic member such that the radial support between adjacent outer sleeve tubes is eliminated thereby allowing the support frame to be folded.

An adjustable bed system includes a base frame structure having first and second frames and a foldable connection mechanism connecting the first and second frame such that the first and second frames are pivotally foldable relative to one another at the foldable connection mechanism. The foldable connection mechanism has at least one connecting bracket assembly, each of which includes a first hinge bracket having first and second end portions, and a second hinge bracket having first and second end portions. The first and second hinge brackets are pivotally connected to one another through a pivot at the first ends. The first and second hinge brackets are respectively mounted on two adjacent end portions of the first and second frames such that the first and second frames are capable of positioning in a plane state or a folded state.

A mattress assembly includes a chassis having top and bottom walls and first and second sidewalls that each extend from the top wall to the bottom wall. Inner surfaces of the walls and the sidewalls define an interior cavity. The top and bottom walls each include a first section that is connected to the first sidewall and a second section that is connected to the second sidewall such that the first sections are pivotable relative to the first sidewall and the second sections are pivotable relative to the second sidewall. The first section of the top wall is pivotable relative to the second section of the top wall and the first section of the bottom wall is pivotable relative to the second section of the bottom wall. A spring assembly is configured to be positioned within the interior cavity.

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 bedsteads. An adjustable support includes an inner bar with one or more cuts and an outer tubular bar with a slot. The inner and outer bars are movably coupled with each other. The adjustable support also includes a mechanism coupled with the outer bar at a position corresponding to the slot of the outer bar. When a cut of the inner bar is aligned with the slot of the outer bar, the mechanism engages with both the cut of the inner bar and the slot of the outer bar, and thus restricts the inner and outer bars from moving with respect to 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.
