A collapsible peripheral frame includes first and second outer lateral bar units, and first and second longitudinal bar assemblies. Each of first and second longitudinal bar assemblies comprises first, second and third longitudinal bar units rotatably connected with each other at their adjacent ends. The first outer lateral bar unit has a first end connected with an end of the first longitudinal bar unit in the first longitudinal bar assembly and a second end rotatably connected with an end of the third longitudinal bar unit in the second longitudinal bar assembly. The second outer lateral bar unit has a first end rotatably connected with an end of the third longitudinal bar unit in the first longitudinal bar assembly and a second end connected with an end of the first longitudinal bar unit in the second longitudinal bar assembly.

A lateral rotation apparatus includes a first frame, a second frame, and a third frame that are independently rotatable. The first frame, the second frame, and the third frame support a person support surface having head, torso, and leg segments. A first pair of legs is positioned below the first frame to rotate a head segment to a head tilt angle in the range of about 7 to about 30 degrees relative to a horizontal support plane. A second pair of legs is positioned below the second frame to rotate a torso segment to a torso tilt angle that is within a range of about 5 degrees to about 10 degrees less than the head tilt angle.

A bedding foundation comprises a connector assembly and a stabilizer assembly at each corner of the product for joining perpendicular first and second trusses. Each stabilizer assembly comprises a first bracket secured to the first truss, a second bracket secured to the second truss and a leg assembly comprising a lag and a threaded rod. One of the first and second brackets has a threaded boss and the other of the first and second brackets has an opening aligned with the threaded boss. The threaded rod extends through the aligned threaded boss and opening of the first and second brackets and the leg abuts the lower bracket to support the foundation above the ground.

The lumbar support mechanism and an adjustable bed having the same. The lumbar support mechanism includes a lumbar support member; first, second, third and fourth support legs; a linkage member; and first and second lumbar support brackets operably attachable to a back platform of the adjustable bed. The first and second support legs are pivotally connected between the lumbar support member and the linkage member; and the third and fourth support legs are pivotally connected between the first and second support legs, and the first and second lumbar support brackets, respectively, such that the lumbar support member is operably movable between a retracted position and an expanded (ejected) position when the linkage member moves between first and second positions. The lumbar support is provided when the lumbar support member is in the ejected position.

Provided is a device for changing a frame angle of a foldable article. The device combines frames using a connecting and assembling member and an elastic string and makes up a leg or a support frame of the foldable article. The connecting and assembling member with which a first end of the elastic string is combined and which has multiple combination grooves in such a manner that the frame combined with a second end of the elastic string is selectively combined with the connecting and assembling member. The first end of elastic string is combined with the connecting and assembling member, and the second end of the elastic string is combined with the frame such that the frame can be elastically operated. The frame is combined with the first end of the elastic string and is elastically insertable into or separable from the connecting and assembling member.

A connecting structure of a bed frame is disclosed. The bed frame includes a frame and bed legs connected under the frame. The frame includes two lateral rods and two longitudinal rods connected to the lateral rods. Respective two sides of the lateral rods or the longitudinal rods are provided with mounting troughs for insertion of respective two end portions of the longitudinal rods or the lateral rods. An outer side surface of each of the mounting troughs is provided with at least one mounting hole. The lateral rods and the longitudinal rods are perpendicularly connected to each other through the mounting troughs. The structure of the bed frame is simple, and the installation is convenient.

A head elevation apparatus configured to be positioned under a mattress may include a base panel and a top panel positioned on the base panel. The top panel may include a center panel hingedly coupled to the base panel. An upper flap may be hingedly coupled to the center panel. A lower flap may be hingedly coupled to the center panel.

The present disclosure relates to the technical field of electric beds, and in particular to a bed body, which solves a technical problem that the width of a bed body of an electric bed is inconveniently adjusted to cause high transportation cost in the prior art. The bed body comprises a bed body main unit and a bed body secondary unit arranged on one side face of the bed body main unit, the bed body main unit is connected with the bed body secondary unit through connectors, and the bed body secondary unit is detachably clamped to the bed body main unit through the connectors.

The lumbar support mechanism includes a lumbar support member; first, second, third and fourth support legs; a linkage member; and first and second lumbar support brackets operably attachable to a back platform of the adjustable bed. The first and second support legs are pivotally connected between the lumbar support member and the linkage member; and the third and fourth support legs are pivotally connected between the first and second support legs, and the first and second lumbar support brackets, respectively, such that the lumbar support member is operably movable between a retracted position and an expanded (ejected) position when the linkage member moves between first and second positions. The lumbar support is provided when the lumbar support member is in the ejected position.
