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 connection system for use in joining structural members of a bed frame together. One of the structural members has a wedge and the other of the structural members has a cavity formed in a receiver. The wedge has a plurality of exterior surfaces that contact with a plurality of interior surfaces formed in the cavity. The wedge may be comprised of a plurality of wedge segments that enter into a plurality of openings in the receiver. The interfitting of the wedge into the receiver make a solid connection that is enhanced by weight of the bedding positioned thereon. The connection resists twisting forces as well as lateral and fore and aft forces.

An adjustable bed frame structure includes a bed frame and bed legs. The bed frame includes a left side rod and a right side rod. A head support rod, a middle support rod and a tail support rod are connected between the left side rod and the right side rod. The head support rod, the middle support rod and the tail support rod each include a left support rod and a right support rod. The left support rod and the right support rod each have a plurality of adjustment holes. The bed legs include side legs and middle legs. Each of the middle legs has a locking portion at a top thereof to mate with the adjustment holes of the left support rod and the right support rod. The width of the bed frame can be adjusted as desired.

Disclosed are foldable bed frames, and oblique supports and connecting mechanisms for foldable bed frames. A foldable bed frame includes first and second sub-frames, and first and second side leg assemblies. The first and second sub-frames, each having top and bottom surfaces, are pivotally connected to each other. The first and second side leg assemblies are pivotally connected to the sub-frames and positioned within the space between the top and bottom surfaces of the sub-frames when folded. In some cases, the foldable bed frame includes a middle leg assembly, oblique supports, connecting pieces, and/or support connecting mechanisms.

An adjustable bed base may be folded in half for shipping without removing the leg assemblies. The leg assemblies are adjustable in length and may be secured in a raised position to facilitate folding the adjustable bed base. To change the length of the leg assembly, a hollow leg is moved inside a hollow receiver and fixed in place by a first push pin assembly. A second push pin assembly inside the hollow receiver fixes the leg assembly in a lowered position and a raised position for storage or shipment. Each hollow receiver is pivotally secured to a mounting bracket welded to a foldable frame of the adjustable bed base.

A novel bed frame is assembled by sliding the ends of hollow metal bars into narrow slots cut into other hollow metal bars. A first bar has an L-shaped first slot. A second bar has a U-shaped second slot and L-shaped third slot, both spanning two adjacent sides of the second bar. An end of the first bar is inserted into the U-shaped second slot, whose width is less than twice the thickness of the metal from which the first bar is made. A portion of the L-shaped first slot aligns with a portion of the L-shaped third slot when the first bar slides into the U-shaped second slot. The top of the third bar is inserted into the aligned first and third slots. The first bar is a longitudinal bar, and the second bar is a lateral bar of the bed frame. The third bar is a support leg.

A bed platform includes a pair of platform sides, each having a bracket receiver; a pair of interfitting brackets received by the bracket receivers, and a leg assembly installed on each of the brackets fixedly connecting the brackets.

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 bed frame includes pivotally connected bedsteads. A bedstead includes an upper frame and a side leg assembly pivotally connected with the upper frame. A bedstead also includes one or more oblique supports each pivotally connected with the upper frame and slidably and rotatably connected with the side leg assembly. A bedstead further includes a shaped lower peripheral support and a plurality of links connecting the lower peripheral support with the upper frame and the side leg assembly. The lower peripheral support can be folded and unfolded along with the upper frame and the side leg assembly.

Disclosed are adjustable supports, bedding support assemblies, and foldable bed frames having adjustable supports, bedding support assemblies or both. A foldable bed frame includes first and second sub-frames, first and second leg assemblies, and a plurality of adjustable supports. First and second sub-frames are pivotally connected with each other at their proximal sides. First and second leg assemblies are pivotally connected with the first and second sub-frames, respectively. Each adjustable support has one end connected to a sub-frame, and the other end connected to a leg assembly. An adjustable support includes movably coupled inner and outer bars, and a locking and unlocking mechanism to selectively restrict the inner and outer tubular bars from moving with respect to each other and thus selectively restrict the leg assembly from rotating with respect to the sub-frame.
