A bed frame includes outer lateral and longitudinal bar units, each having a first end and a second end. Each of first, second, third, and fourth longitudinal bar units includes an upper longitudinal bar and a lower longitudinal bar. The first ends of the first and second longitudinal bar units are rotatably connected with each other. The first ends of the third and fourth longitudinal bar units are rotatably connected with each other. Of each respective longitudinal bar unit, the second end of the upper longitudinal bar is movably connected with the first or second end of a corresponding lateral bar unit, and the second end of the lower longitudinal bar is fixedly connected with the first or second end of the corresponding lateral bar unit.

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.

Adjustable mattress assemblies and processes including an adjustable mattress foundation dimensioned to support a mattress configured to accommodate two supine users during use thereof includes a foundation frame including a first sub-foundation configured with at least one motorized actuator to effect inclination or declination of the mattress support surface and an abutting second sub-foundation free of a motorized actuator. The second foundation is mechanically coupled to the first foundation such that articulation of the first sub-foundation results in a similar articulation in the second foundation. The first and second foundations have similar length, height and width dimensions, which collectively approximates the size of the oversized mattress configured to accommodate two supine users, e.g., king size, queen size, California king size, or the like.

Disclosed are connectors and collapsible bed frames. A collapsible bed frame includes lateral and longitudinal bar units. Between each of two adjacent lateral bar units, a first longitudinal bar unit is disposed at a first side of the collapsible bed frame and a second longitudinal bar unit is disposed at a second side of the collapsible bed frame. The first and second longitudinal bar units and the two adjacent lateral bar units are rotatably connected with each other by connectors that enable the collapsible bed frame to contract and expand while the lateral and longitudinal bar units are connected with each other.

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 assemblable mattress support can be shipped with all of its components compactly packed into the headboard. The mattress support includes a foldable longitudinal bar, a lateral bar, side panels, wooden slats, block legs and a footboard, all of which fit inside a compartment in the headboard. In an assembled state of the mattress support, a first connector at one end of the longitudinal bar attaches to a third connector on the outside of the headboard. A second connector at the other end of the longitudinal bar attaches to a fourth connector on the footboard. The middle of the lateral bar connects to the middle of the longitudinal bar. The block legs are attached to the bottom sides of the headboard and footboard. The slats are attached to one another by fabric ribbons and are placed in parallel over the longitudinal bar and support ledges on the side panels.

A nursing bed including a bed body, provided with a plurality of combined bed boards, at least one of the plurality of combined bed boards being provided with one or more pressure sensors, and a comparator, connected to the one or more pressure sensors. The comparator is configured to compare pressure data transmitted by the one or more pressure sensors with a predetermined pressure value and output a warning signal when the pressure data transmitted by the one or more pressure sensors is greater than or equal to the predetermined pressure value. A timer, is connected to the comparator, and with respect to each of the pressure sensors, configured to start timing when the warning signal is received and output an alarm signal when a preset time is reached, and an alarm device, is connected to the timer, and configured to give an alarm after the alarm signal is received.

An adjustable foundation and process includes a mattress support surface including a head/back section hingedly connected to an intermediate section at one end and a leg/foot section hingedly connected to the intermediate section at another end, wherein the intermediate section includes a first second portions, wherein the first portion is hingedly connected to the head/back section and the second portion is hingedly connected to the leg/foot section. The intermediate section is configured to increase in length upon articulation of the head/back section and/or the leg/foot section from a flat position or an increase in inclination of any section. Likewise, the intermediate section is configured to decrease in length upon articulation of the head/back section and/or the leg/ foot section from an inclined position to a flat position or a decrease in length upon declination of any section.

A bedding foundation has a linear actuator for moving a roller carriage forward and backwards. The roller carriage includes wheels which move along rails supported below a rigid platform having an opening extending through the platform. The roller carriage includes a lifter which raises and lowers a roller independently of the movement of the linear actuator. Regardless of the position of the linear actuator, the roller may be raised or lowered. The roller moves back and forth inside the opening extending through the rigid platform and imparts a massage movement to a mattress above the foundation.
