Disclosed are support assemblies and foldable bed frames. A foldable bed frame includes first and second frames, each having left and right frame bars. A foldable bed frame also includes a support assembly having first and second link units. The first link unit is slidably and rotatably coupled with proximal end portions of the left and right frame bars of the first frame, and the second link unit is slidably and rotatably coupled with proximal end portions of the left and right frame bars of the second frame. The first and second link units are fixedly coupled with each other with a space in between. When folded, the proximal end portions of the left and right frame bars of the first and second frames are disposed in the space between the first and second links, minimizing a length of the foldable bed frame when folded.

A bed can include one or more connectors for connecting components of the bed. For example, a frame can include a fastening mechanism for releasably connecting a cross-member to a longitudinal support. Another example includes connectors for connecting and aligning a foundation with a frame.

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.

A bedstead includes a frame, an interior support removably coupled with the frame, and outer legs supporting the frame when the bedstead is set up. The interior support includes an inner leg, first connectors disposed circumferentially around the inner leg and connecting bars. Each connecting bar has one end pivotally connected with the inner leg through a first connector, and the other end to be removably coupled with the frame. When in use, the first connector restricts the movement, in particular, the rotation of the connecting bar, and thus enhances the overall structural stability of the bedstead.

A foldable mattress support includes a headboard, a central hinge portion and first and second portions of a bedboard frame. The first and second portions are pivotally attached to the central hinge. A longer first strut is pivotally attached at a first location to a side bar of the first portion and at a third location to a post of the headboard. A shorter second strut is pivotally attached at a second location to the side bar and at a fourth location to the post. The second location is closer to the head end of the first portion than is the first location, and the fourth location is closer to the top of the post than is the third location. The struts rotate the headboard from an unfolded state that is perpendicular to the first portion down to being parallel and adjacent to the first portion in a collapsed state.

A motorized bed includes a bed frame, a foot rest, a footrest actuator, a backrest, a backrest actuator, and a linkage part. The bed frame includes a first cross bar and a second cross bar. The footrest is rotatably mounted to the bed frame. The footrest actuator is mounted between the footrest and the first cross bar and configured to drive the footrest to rotate relative to the bed frame. The backrest is rotatably mounted to the bed frame. The backrest actuator is mounted between the backrest and the second cross bar and configured to drive the backrest to rotate relative to the bed frame. The linkage part is fixedly connected between the first cross bar and the second cross bar such that a force introduced by either of the footrest motor and the backrest motor is supported by both of the first cross bar and the second cross bar.

Disclosed are couplers, bedspreads and bedsteads. A bedspread includes a bed cloth, a bed drape and a plurality of couplers. The bed cloth has a peripheral edge corresponding to an upper peripheral frame of a bedframe. The bed drape is coupled or integrally formed with the bed cloth along the peripheral edge, and hangs down when in use. Each coupler includes a plate, a hook, and an elastic strap connecting the plate with the hook. The plate is disposed on an interior side of the bed cloth at or proximal to the peripheral edge of the bed cloth. The hook is configured to couple with a lower support of the bedframe.

A foldable bed frame includes left and right longitudinal stands. Each of the left and right longitudinal stands includes first and second longitudinal bars pivotally connected to a third longitudinal bar at first and second pivotal points, respectively. Each of the left and right longitudinal stands also includes first, second and third vertical legs fixedly coupled to or integrally formed at the first, second and third longitudinal bars, respectively. The distance between the first vertical leg and the first pivot point is different than the distance between the second vertical leg and the second pivot point such that when folded, one of the first and second vertical legs is disposed in an interior side of the folded left or right longitudinal stand with respect to the other of the first and second vertical legs.

A foldable supporting frame includes a first frame set, a second frame set, and a first link at each of the left and right sides of the foldable supporting frame to pivotally connect the first frame set with the second frame set. Each of the first and second frame sets includes a first frame unit, a second frame unit, and a second link at each of the left and right sides of the foldable supporting frame to pivotally connect the first frame unit with the second frame unit. The first link allows the first and second frame sets to fold and unfold with respect to each other, and the second link allows the first and second frame units to fold and unfold with respect to each other. As a result, the supporting frame can be folded at least three times and has a much smaller folded size.

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.
