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.

Disclosed are collapsible beds and bed frames. A collapsible bed frame includes first and frame units disposed side by side and connected with each other at their proximal sides. Each of the first and second frame units comprises a plurality of bar units. Adjacent bar units are connected with each other and rotatable with respect to each other along one or more axes each substantially perpendicular to a first plane defined by a top surface of the collapsible bed frame when it is expanded. The first and second frame units can contract and expand while remaining on the first plane and while connected with each other.

A collapsible peripheral frame includes first and second outer lateral bar units, and first and second longitudinal bar assemblies. Each of first and second longitudinal bar assemblies comprises first, second and third longitudinal bar units rotatably connected with each other at their adjacent ends. The first outer lateral bar unit has a first end connected with an end of the first longitudinal bar unit in the first longitudinal bar assembly and a second end rotatably connected with an end of the third longitudinal bar unit in the second longitudinal bar assembly. The second outer lateral bar unit has a first end rotatably connected with an end of the third longitudinal bar unit in the first longitudinal bar assembly and a second end connected with an end of the first longitudinal bar unit in the second longitudinal bar assembly.

A folding bed frame that includes four vertical faces: two ends and two sides. Each face is formed by two slanting bars that are cross hinged together. The upper and lower ends of adjacent slanting bar sets are hinged together to form the whole frame structure. The two vertical faces are corresponding or symmetric, and each includes two sets of slanting bar sets that are hinged through to middle sections of the upper and lower angle plates. There is a vertical rod part on the cross-hinging point of each set of slanting bar set, and its movable position is set by a slide bushing. There is a barrier that is on the cross-hinging point of one of the slanting bars. The barrier can contact the upper part vertical bar, and form two support points with the slide bushing for the vertical bar part.

The present disclosure relates to the technical field of electric beds, and in particular to an integrated folding bed, which solves a technical problem that the width of a bed body is inconveniently adjusted in the prior art. The integrated folding bed comprises a bed body, bed feet and a bed frame, and the bed body is formed by multiple sequentially connected folding main bed boards, wherein an expanding bed board for widening the bed body is integrally arranged on one side face of the main bed board, the main bed board and the expanding bed board are connected through a hinge, two leaves of the hinge are respectively and fixedly mounted on an upper surface of the main bed board and an upper surface of the expanding bed board, and a pin of the hinge is arranged upwards.

A foldable supporting assembly includes an inner lateral bar unit, and first, second, third and fourth longitudinal bar units. The first and second longitudinal bar units are disposed at a first side, and rotatably connected with the first and second ends of the inner lateral bar unit. The third and fourth longitudinal bar units are disposed at a second side, and rotatably connected with the first and second ends of the inner lateral bar unit. When folded, one of the first and second longitudinal bar units is disposed between the inner lateral bar unit and the other one of the first and second longitudinal bar units, and one of the third and fourth longitudinal bar units is disposed between the inner lateral bar unit and the other one of the third and fourth longitudinal bar units.

A bed frame has left, intermediate and right longitudinal support bars, each having two main body sections and an intermediate section connected between two main body sections, via a connecting sheet. A first through hole is disposed at an end of each of the main body sections adjacent to the intermediate section. The connecting sheet is provided with a second through hole on a side connected to the main body section. When the second through hole is aligned with the first through hole, a support bar pivot shaft can run through the first through hole and second through hole so that the two main body sections can rotate about their respective support bar pivot shafts in a vertical plane relative to the intermediate section. Folding the bed frame is simple and easy to implement, and the bed frame, in a folded state, facilitates transportation and compact storage.

A bed frame has a left longitudinal support bar, a right longitudinal support bar and an intermediate longitudinal support bar, two sliding sleeves slidably disposed on the intermediate longitudinal support bar, wherein each of the sliding sleeve is provided with a bracket. The bed frame further comprises four connecting rods connected between the left longitudinal support bar or right longitudinal support bar and the intermediate longitudinal support rod, one end of each of the connecting rods is pivotally connected to the left or right longitudinal support bar, the other end is pivotally connected with the bracket so that the end of the connecting rod mounted on the bracket moves along with the sliding sleeve. The bed frame is simple and easy to fold and un-fold, while providing improved strength and stability.

The invention discloses a self locking folding bedstead, which comprises two transverse rods and self locking cross mechanisms. The self locking cross mechanism comprises a shearing mechanism, two second connecting rods and two third connecting rods, and the shearing mechanism comprises two first connecting rods. One end of the second connecting rod can be rotatably connected to the transverse rod, the other end can be rotatably connected to the first connecting rod, the third connecting rod can be rotatably connected to the second connecting rod, and the third connecting rod can be rotatably connected to the other first connecting rod. The shearing mechanism, two second connecting rods and two third connecting rods cooperate to form two sets of symmetrically arranged hinge four connecting rods mechanism. The self locking cross mechanism is provided with a limiting mechanism to limit the maximum angle of deployment, and the angle of the opening facing downward formed by the two third connecting rods of the self locking cross mechanism at the maximum deployment angle is greater than 180 degrees. It has the following advantages: the mechanism can be kept in the self locking state, so that the bed width and bed height are fixed, so that the bed surface can be tightened, stable and non-dumping, comfortable to use.

A foldout bed housing with four panels is described. The housing includes a bed tray comprising a first panel, a second panel, a third panel, and a fourth panel, wherein the first and second panels are hingeably coupled and the third and fourth panels are hingeably coupled, and one or more fasteners for rigidly coupling the first and second panels with the third and fourth panels in a planar surface. The housing also includes a first and second side wall, a front panel, a first back panel, a top panel, and a counterbalance mechanism. Each housing component can be shipped in a packed configuration for economic shipping. Upon delivery, the combination can be unpacked for quick and easy installation.
