Disclosed are connectors and collapsible bed frames. A collapsible bed frame includes first and second frame units disposed side by side. Each of the first and second frame units comprises a plurality of bar units with adjacent bar units rotatably connected with each other. A collapsible bed frame also includes an inner lateral bar unit disposed between the first and second frame units, and rotatably connected with the first and second frame units. During contraction and expansion, the first frame unit, the second frame unit and the inner lateral bar unit remain substantially on a first plane defined by a top surface of the collapsible bed frame when it is expanded.

A foldable stand includes first and second supports, each having first and second portions. The foldable stand also includes first and second leg assemblies, each having a pair of crossed bars. The pair of crossed bars of the first leg assembly is pivotally connected to the first portions of the first and second supports. The pair of crossed bars of the second leg assembly is pivotally connected to the second portions of the first and second supports. The foldable stand further includes at least one locking assembly to selectively lock the pair of crossed bars of the first or second leg assembly to prevent the foldable stand from accidental folding.

A foldout bed is described. The foldout bed has a left side wall, a right side wall, and a top panel that extends between and attached to the top ends of the two side walls. The bottom end of each side wall is coupled with a counterbalance mechanism. A bed tray is pivotally coupled with a the counterbalance mechanisms and is transitionable between an open configuration and a closed configuration. The bed tray provides a unitary planar surface that is configured to support a mattress and a person when in the open configuration. Each counterbalance mechanism has a frame and a piston that attaches the frame to the bed tray. The frame has a base flange disposed perpendicular to the side walls and located at the bottommost end of the counterbalance mechanism against a base plate of the wall.

An expandable and collapsible support device for multiple use enables attaining an expanded open state for use or return to a compact closed state in mere seconds. The device includes an accordion-style frame that expands laterally from a compact closed state to an expanded open state for use, and a material support cover forming the top of the device and attachable to the frame to provide a support surface above ground level for the device.

A travel cot has multiple lateral fences, multiple vertical posts, and a bottom frame. Each of the lateral fences is rotatably mounted between every two of the adjacent vertical posts, and includes a middle unit, two surrounding frames, and two lateral locks. The bottom frame includes a central body and multiple bottom links. The bottom links are disposed between the central body and the vertical post. In a folding process, the central body moves upward to move the vertical posts closer to each other, and then the lateral locks switch into an unlocked state, thus the middle units move downward and the lateral fences are folded. In the expanding process, the central body moves downward to expand the vertical posts via the bottom links, and then the lateral fences expand, and the middle units move upward to switch the lateral locks into the locked state.

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 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 piece. A first through hole is disposed at an end of each of the main body sections adjacent to the intermediate section. The connecting piece 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 foldable bed assembly includes first and second frame units and two hinge units. The first frame unit includes two first longitudinal frames, and a first transverse frame. The second frame unit includes two second longitudinal frames and a second transverse frame. The second frame unit is pivotable relative to the first frame unit and convertible between a normal state, where the first transverse frame is spaced apart from the second transverse frame, and a folded state, where the second longitudinal frames are respectively overlaid on the first longitudinal frames and the first transverse frame is overlaid on the second transverse frame.

A bed with a three-way folding mechanism includes a frame, several bed legs and several load-bearing bars, the frame is enclosed by two horizontal bars and two vertical bars in the horizontal direction, the bed legs are mounted on the frame in the vertical direction, the horizontal bars include at least two first bars rotatably connected by an hinged structure, the two first bars are foldable in the vertical direction, the vertical bars include at least two second bars hinged together by a rotation-connecting structure, so that the two second bars are foldable horizontally toward the interior of the frame, the folding mechanism includes an assembly base, a shaft and a strip slot, the assembly base is fixed to the vertical bar with an extension portion sleeved on the outer circumference of the horizontal bar and is hinged to the slot formed on the horizontal bar through the shaft.

A foldable bed (50) comprising: a foldable frame (505) along at least one axis comprising a foldable rod (510), at least two legs (515), each leg being attached to the frame by a connection (520), said connection allowing for the positioning of said leg according to an unfolded position and a folded position and the foldable rod being associated with each connection on either side of the folding axis, in which: each connection comprises an orifice (525) passing through said connection and each leg has an attachment (530) to a flexible wire (535) connecting two legs and passing through the folding axis of the frame, the wire being tensioned when the rod is unfolded, the tension of the wire causing the positioning of the legs in the unfolded position.
