Disclosed are supports, folding mechanisms and foldable supporting frames. A foldable supporting frame includes a plurality of bent bars, folding mechanisms and supports. The bent bars are connected to each other by the folding mechanisms and the supports to form upper and lower frames of the foldable supporting frame. The foldable supporting frame can be folded and unfolded by rotating any one of the bent bars. When unfolded, the supports hold the upper frame in place and keep it flat and stable. When folded, the folding mechanisms and the supports allow the bent bars to move toward each other and fold onto each other. The folded supporting frame is compact and of a regular shape, making it easier to handle, package, store, and transport.

A multi-purpose folding frame and a multi-purpose folding frame module are disclosed. The multi-purpose folding frame comprises a surface board and two leg frames installed on the two ends of the bottom surface of the surface board, which can be folded in relation to the surface board for convenient storage. The bottom end surface of the surface board is configured with a support lock frame. The support lock frame and the hinge rod hinged on the lower end surface of the surface board are fixed on the support lock bar on the tip end of the hinge rod. The inner side of the leg frame is configured with a lock seat. The lock seat is configured with a lock groove.

A foldable bed frame includes frame units pivotally connected to each other by one or more connecting assemblies. A frame unit includes upper and lower frames, legs or links connected to the upper and lower frames, and limiting pieces disposed on the upper and lower frames to limit rotation angles or directions of the legs or links. A connecting assembly includes middle leg(s) or middle bar(s), and connecting pieces. When folded, the bed frame is compact. When unfolded, the bed frame provides storage spaces underneath, and facilitates positioning and holding of bed shirts/sheets.

A folding furnishing apparatus includes first members that support at least one flexible panel in a set-up configuration; second members that support the plurality of first members; first joints that connect the plurality of first members and that in the set-up configuration define mutually skewed axes about which the furnishing cannot be folded, thus locking the first members in extended positions; and second joints that connect the second members to the first members. The second joints in the set-up configuration define mutually parallel axes about which the second members can be folded to a mutually nested configuration. The first joints in the mutually nested configuration then define mutually parallel axes about which the first members can be folded to a collapsed configuration.

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 portable surface for lounging or sleeping with an elevated leg rest and backrest, and a seat that rests on the ground or other supporting surface such as a car seat, truck bed or bleacher. The various parts of the chair can be folded up and nest inside of each other in a compact bundle that may fit in a backpack or a map pocket for easy portability. When folded up, a strap can be tightened around the apparatus preventing the innards from unfolding, creating a smaller profile.
