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 zero gap foldable powered bed comprises a bed frame and a sliding mechanism disposed upon said bed frame. The bed further comprises back, lumbar, seat, thigh, and leg decks operatively connected to the sliding mechanism, and the bed frame includes a head end frame member which is disposed within a vertically oriented plane. Linear actuators are operatively connected to the back and leg decks, and when the back deck is elevated or lowered, the sliding mechanism slides upon the bed frame so as to maintain the head end frame member, to which a headboard may be attached, within the vertically oriented plane such that a free end portion of the back deck will always be disposed immediately adjacent to the vertically oriented plane such that the back and shoulders of a person, lying or sitting upon the bed, will remain close to a nightstand, which may be disposed close to the bed, such that articles disposed upon the nightstand are always readily accessible.

Linear dual actuator for lying or sitting furniture having at least two sections (2,3), which with one end is rotatably embedded in the article of furniture and where each section (2,3) with an arm (5,7) secured to a pivot shaft (4,6) can be adjusted by means of the linear dual actuator. The dual actuator comprises a housing (8) with a drive at each end, which comprises an electric motor (11), which through a transmission (12) is in driving connection with a spindle (13). On the spindle (13) is arranged an activation element (14) with a spindle nut in engagement with the spindle (13), where the activation element (14) can be brought into engagement with the arm (5,7) for adjusting the sections (2,3). In case of power failure there is the problem that the back rest and leg rest section cannot be lowered to a plane level, which can make the bed uncomfortable or completely impossible to sleep in. This problem is solved in that a rotating element in the drives comprises a connection (21), which is accessible from the outer side of the housing (8) for connecting a tool, e.g. an Allen key (22) for driving the respective drives for the back rest and leg rest section (2,3) for lowering of these to a horizontal position.

The lumbar support mechanism and an adjustable bed having the same. The lumbar support mechanism includes first and second lumbar lifting assemblies. Each lumbar lifting assembly has a fixing bracket, a first support leg, a second support leg, a bearing member, and a lifting support bracket. The first support leg is pivotally connected between the bearing member and the lifting support bracket. The second support leg is pivotally connected between the fixing bracket and the first support leg. A lumbar support member is connected to the lifting support brackets of the first and second lumbar lifting assemblies. A linkage member is pivotally connected to the bearing members of the first and second lumbar lifting assemblies such that the lumbar support member is operably movable between a retracted position and an ejected position when the linkage member moves between first and second positions.

An electric bed having no bed board and being covered with a surface material includes: a foldable bedframe jointed through connectors and connected with bed legs, overturningly foldable frames disposed on the bedframe, a drive device disposed on the bedframe (1), a surface material covered directly onto a plurality of frames, and a tensioning mechanism for tensioning the surface material at a surface of the frames; the tensioning mechanism includes embedded strips and pipes, and may further include a clamp fastener; when the surface material is in a tensioned state, an embedded strip connected at one end of the surface material is limited within a limiting slot of a pipe at one side, and another embedded strip connected at another end of the surface material is limited within a limiting slot of another pipe at the opposite side.
