A bedframe, comprising an enclosing frame and several support legs installed on the underside of enclosing frame for supporting the enclosing frame and enclosing sheets located between the support legs; an outer opening groove extended in the length direction is located inward in the lateral surface of support leg; the opening width of the outer opening groove is larger than or equal to the inner width of outer opening groove. The enclosing sheet extends out of the support leg along the opening of outer opening groove. In the assembling of enclosing sheet, the first inner tube and the side edge of enclosing sheet are flat put in the opening of outer opening groove along the side edge of support leg, the operation is easy, convenient for later disassembly and cleaning.

Disclosed are adjustable supports and frames. An adjustable support includes an inner bar, an outer bar and a locking/unlocking mechanism for controlling the relative movement of the inner and outer bars. The locking/unlocking mechanism includes a casing pivotally connected with the outer bar, a pin coupled with the casing, and an elastic member to engage the pin with the inner and outer bars.

A folding bedstead comprises a first and second unit bedsteads hinged through one or more connecting positions. The unit bedsteads comprise a frame comprising a plurality of corners and an interior. A plurality of bars are disposed in one direction of the frame internally. Each connecting member is disposed in a corner and comprises a body and a first and second lugs. The body is coupled to the corner. The first and second lugs are disposed in the body. A supporting leg, hinged with the first lug, is disposed thereon. A diagonal bracing member is disposed on the second lug wherein one end of the diagonal bracing member is coupled with the second lug, and another end of the diagonal bracing member is coupled with the supporting leg. A third lug is disposed on the body wherein one side of the supporting leg presses against the third lug when unfolded.

A shippable mattress foundation that assembles quickly without any tools, ship in a small Fedex/UPS package, fits easier on a skid in a retail store, and allows an end customer to take it home in a car. It holds over 2500 lbs. of distributed weight, allows for easy attachment of a headboard of various dimensions, has an attractive optionable, washable and detachable outer stylish cover, and is designed to allow up to 12 of underneath storage. Also has stamped holes for receipt of the cross slats and a bespoken plastic clip for adjoining the cross slats.

A novel form of mattress foundation a part of bedding system having a capability for folding and portability with light weight and higher strength material where the mattress foundation comprising of metal structure made up of wire in square shape to provide a smooth surface and is cut into a head section and foot section hinged from middle to provide folding and unfolding possibility. The top outer ring of square tube is 14 legs that make up 6 pivoting circular pipes that when unfolded give the foundation the correct height and strength to act just like a normal foundation/box spring sleep system.

In order to maximize spatial utilization and to minimize the volume of a thermotherapy bed so that the thermotherapy bed can be easily stored or moved, the thermotherapy bed includes: a bed body having a thermotherapy device placed therein; side frames connected to both side surfaces of the bed body, respectively; and bed legs configured to support the bed body and connected to the side frames, respectively, wherein the thermotherapy device is placed in a center of the bed body and forms a protrusion on a bottom surface of the bed body, and the bed legs are folded to face an inside of the bed body and are accommodated in spaces formed at both sides of the thermotherapy device.

Disclosed is a joint device of a folding bed, which includes: a first connecting arm for connecting a supporting leg of the folding bed, with a through-hole provided thereon, a second connecting arm for connecting a frame of the folding bed, the second connecting arm being connected on an upper end part of the first connecting arm through a rotating shaft, and a connection locking mechanism including two pressing pieces arranged respectively on each side of the second connecting arm, each of the pressing pieces being connected with a hook, and the two pressing pieces being slidable toward or away from each other through springs, so that the hook passes through the second connecting arm and is hooked to or detached from the through-hole, thereby allowing the second connecting arm and the first connecting arm to be locked or unlocked relatively to each other.

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.

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.

A bed frame assembly has diagonal struts that lock leg supports into place using novel locking mechanisms. A leg support is pivotally attached to the bedboard frame, and a slotted bracket is welded to a cross bar of the frame. One end of a diagonal strut is pivotally attached to the leg support, and a bolt with a conical washer and a wing nut is attached to the other end. The strut is attached to the slotted bracket by inserting the bolt into a curved slot in the bracket. The bracket also includes a stopper brace that extends perpendicular to the body of the bracket. A side of the end of the strut pushes against the stopper brace when the conical washer is pressed into the end of the curved slot and the wing nut is tightened. The stopper brace prevents the bolt from sliding out of the curved slot.
