A foldable bed includes a bed frame structure having a back frame and a leg frame connecting to the back frame such that the back frame and the leg frame are pivotally foldable relative to one another along a length direction of the foldable bed; and a plurality of boards detachably attached onto the bed frame structure along the length direction of the foldable bed, wherein each board comprises a pair of panels arranged along a width direction of the foldable bed.

Disclosed are collapsible beds and bed frames. A collapsible bed frame includes first and frame units disposed side by side and connected with each other at their proximal sides. Each of the first and second frame units comprises a plurality of bar units. Adjacent bar units are connected with each other and rotatable with respect to each other along one or more axes each substantially perpendicular to a first plane defined by a top surface of the collapsible bed frame when it is expanded. The first and second frame units can contract and expand while remaining on the first plane and while connected with each other.

An adjustable bed system includes first and second frames; a back lifting assembly having a back lifting bracket pivotally connected to the first frame and a back lifting actuator pivotally connected between the back lifting bracket and the first frame for operably driving the back lifting bracket to pivotally move in an upward or downward rotating direction relative to the first frame; a leg lifting assembly having a leg lifting bracket pivotally connected to the second frame structure and a leg lifting actuator pivotally connected between the leg lifting bracket and the second frame for operably driving the leg lifting bracket to pivotally move in an upward or downward rotating direction relative to the second frame; and a foldable connection mechanism connecting the first and second frames such that the first and second frames are pivotally foldable relative to one another at the connection mechanism.

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 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.

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 frame includes first and second mounting assemblies pivotally connected with each other. The frame also includes first, second and third leg assemblies. The first leg assembly is pivotally connected the first mounting assembly. The second leg assembly is pivotally connected with the second mounting assembly. The third leg assembly is pivotally connected with both of the first and second mounting assemblies. The frame further includes one or more supporting assemblies to enhance stability of the frame. A supporting assembly includes first, second and third members and a controller. The first member is connected with the third leg assembly. The controller is connected with the first member and selectively movable along the first member. The second member is pivotally connected with the controller and the first mounting assembly, and the third member is pivotally connected with the controller and the second mounting assembly.

A frame includes a mounting assembly having a plurality of mounting members connected to or integrally formed with each other. The frame also includes first and second leg assemblies pivotally connected with the mounting assembly at first and second sides of the mounting assembly, respectively. The first and second leg assemblies are foldable into an interior defined by the mounting assembly and, when folded, are substantially on the same plane as the mounting assembly. The frame further includes one or more supporting assemblies to help stabilize the first and second leg assemblies and support the mounting assembly when the frame is unfolded. Thus, the frame is compact when folded and stable when in use.

Disclosed are motorized beds and bed frames. A motorized bed frame includes a lower frame and an upper frame disposed above the lower frame. At one or each of first and second sides of the motorized bed frame, the motorized bed frame also includes an actuating unit and a gearing unit to move and position an upper sub-frame of the upper frame with respective to the lower frame. The upper sub-frames at the first and sides can be independently positioned to meet individual needs. In some cases, the motorized bed frame includes additional or optional components to help dispersing the load and stabilizing the bed frame during operation.
