Abstract

A bed frame is provided that includes a lower frame and an upper frame having a first section, a second section and a third section. The second section is positioned between the first section and the third section. The first section is pivotable relative to the lower frame. The third section is fixed relative to the lower frame. The second section is pivotable relative to the first section and the third section. A lifting assembly includes a first end that is coupled to the lower frame and a second end that is coupled to the second section. The lifting assembly is configured to selectively move the second section toward and away from the lower frame.

First claim

What is claimed is:

1. A bed frame comprising:
a lower frame;
an upper frame comprising a first section, a second section and a third section, the second section positioned between the first section and the third section, the first section being pivotable relative to the lower frame, the second section being pivotable relative to the first section and the third section; and
a lifting assembly comprising a first end that is coupled to the lower frame and a second end that is coupled to the second section, the lifting assembly being configured to selectively move the second section toward and away from the lower frame,
wherein the lifting assembly is configured to move the bed frame between a first configuration in which the sections are parallel to one another and a second configuration in which the first and third sections each extend at an obtuse angle relative to the second section, and
wherein the third section is non-movable relative to the lower frame as the bed frame moves between the first and second configurations.

2. A bed frame as recited in claim 1 , wherein the second section comprises a first portion that is coupled to the first section and a second portion that is coupled to the third section, the second portion being pivotable relative to the first portion.

3. A bed frame as recited in claim 1 , wherein the second section comprises a first portion that is pivotably coupled to the first section and a second portion that is pivotably coupled to the third section, the second portion being pivotable relative to the first portion.

4. A bed frame as recited in claim 1 , wherein the lower frame comprises a planar surface and a leg that extends from the planar surface, the bed frame comprising a pin that extends through the leg and the first section to allow the first section to pivot relative to the leg.

5. A bed frame as recited in claim 1 , wherein the lower frame comprises a planar surface and a leg that extends from the planar surface, the third section being fixed to the leg.

6. A bed frame as recited in claim 1 , wherein the lower frame comprises a planar surface and a leg that extends from the planar surface, the third section comprising a bottom surface that is fixed to the leg and an opposite top surface that extends parallel to the planar surface.

7. A bed frame as recited in claim 1 , wherein the lifting assembly comprises a hydraulic cylinder and a piston that is movable relative to the hydraulic cylinder.

8. A bed frame as recited in claim 1 , wherein the lifting assembly comprises a hydraulic cylinder and a piston that is movable relative to the hydraulic cylinder, the hydraulic cylinder being pivotably coupled to the lower frame and the piston comprising an end that is coupled to a scissor jack assembly of the lifting assembly.

9. A bed frame as recited in claim 1 , wherein the lifting assembly comprises:
a hydraulic cylinder and a piston that is movable relative to the hydraulic cylinder, the hydraulic cylinder being pivotably coupled to the lower frame and the piston comprising an end that is coupled to a scissor jack assembly of the lifting assembly; and
a controller that includes a hydraulic pump and electronic circuitry that connects the hydraulic pump and the hydraulic cylinder to allow the hydraulic pump to move the piston relative to the hydraulic cylinder.

10. A bed frame as recited in claim 1 , wherein the lifting assembly comprises a scissor jack assembly.

11. A bed frame as recited in claim 1 , wherein the first section comprises a first portion and a second portion that is movably connected to the first portion by a bracket, the bed frame comprising an actuator, the actuator including a shaft that is coupled to a flange of the second portion, the actuator including a coupling that engages a flange of the first portion, an end of the shaft being positioned within the coupling, the coupling being rotatable relative to the shaft to increase and decrease a distance between the first portion and the second portion.

12. A bed frame as recited in claim 1 , wherein the lifting assembly comprises a scissor jack assembly, the scissor jack assembly comprising a first and second links, the links each having a first end that is coupled to the lower frame and a second end that is coupled to the second section.

13. A bed frame as recited in claim 12 , wherein the scissor jack assembly comprises a pin that extends through the first link and the second link to allow the first link to pivot relative to the second link.

14. A bed frame as recited in claim 12 , wherein the lifting assembly comprises a hydraulic cylinder and a piston that is movable relative to the hydraulic cylinder, the hydraulic cylinder being pivotably coupled to the lower frame and the piston comprising an end that is coupled to one of the links.

15. A bed frame as recited in claim 12 , wherein the lifting assembly comprises:
a hydraulic cylinder and a piston that is movable relative to the hydraulic cylinder, the hydraulic cylinder being pivotably coupled to the lower frame and the piston comprising an end that is coupled to one of the links; and
a controller that includes a hydraulic pump and electronic circuitry that connects the hydraulic pump and the hydraulic cylinder to allow the hydraulic pump to move the piston relative to the hydraulic cylinder.

16. A bed frame comprising:
a lower frame;
an upper frame comprising a first section, a second section and a third section, said second section positioned between the first section and the third section, the first section being pivotable relative to the lower frame, the second section being pivotable relative to the first section and the third section; and
a lifting assembly positioned between the lower frame and the second section, the lifting assembly being configured to selectively move the second section toward and away from the lower frame and to move the bed frame between a first configuration in which the sections are parallel to one another and a second configuration in which the first and third sections each extend at an obtuse angle relative to the second section, the third section being non-movable relative to the lower frame as the bed frame moves between the first and second configurations.

17. A bed frame as recited in claim 16 , wherein the lifting assembly comprises a scissor jack assembly, the scissor jack assembly comprising a first and second links, the links each having a first end that is coupled to the lower frame and a second end that is coupled to the second section.

18. A bed frame as recited in claim 17 , wherein the lifting assembly comprises a hydraulic cylinder and a piston that is movable relative to the hydraulic cylinder, the hydraulic cylinder being pivotably coupled to the lower frame and the piston comprising an end that is coupled to one of the links.

19. A bed frame as recited in claim 17 , wherein the lifting assembly comprises:
a hydraulic cylinder and a piston that is movable relative to the hydraulic cylinder, the hydraulic cylinder being pivotably coupled to the lower frame and the piston comprising an end that is coupled to one of the links; and
a controller that includes a hydraulic pump and electronic circuitry that connects the hydraulic pump and the hydraulic cylinder to allow the hydraulic pump to move the piston relative to the hydraulic cylinder.

20. A bed frame comprising:
a lower frame comprising a planar surface and spaced apart first and second legs that each extend away from the planar surface;
an upper frame comprisin
