Abstract

A bed having a frame and a deck is disclosed. The deck has at least a horizontal position and a chair position. The deck has an adjustable-length foot section.

Claims

1. A bed comprising:

a frame,

a deck supported by the frame, the deck including movable sections configurable for the deck to assume at least a horizontal position and a chair-like position, the movable sections including at least a head section and a foot section spaced from the head section, the foot section having an adjustable length,

a contracting member coupled to the foot section and being movable between an extended position and a retracted position, wherein the length of the foot section is shorter when the contracting member is in the retracted position and the length of the foot section is longer when the contracting member is in the extended position, and

a pivoting member coupled to the foot section and pivotable relative to the frame, wherein the contracting member is arranged to extend away from the pivoting member in a longitudinal direction relative to the pivoting member, and is independently movable relative to the pivoting member to adjust the length of the foot section as the contracting member moves between the extended and retracted positions.

2. The bed of claim 1, wherein the pivoting member is pivotably coupled to another section of the deck located between the head section and the foot section.

3. The bed of claim 2, wherein the pivoting section is pivotable between a horizontal position and a vertical position.

4. The bed of claim 1, comprising first and second linkages coupling the pivoting member and the contracting member.

5. The bed of claim 4, wherein the first linkage is coupled to the pivoting member and the second linkage is coupled to the contracting member.

6. The bed of claim 5, wherein movement of at least one of the linkages causes movement of the contracting member.

7. The bed of claim 1, wherein the contracting member is positioned to slide across a top surface of the pivoting member.

8. A bed comprising:

a frame,

a deck configured to support a mattress in at least a horizontal position and a chair position, the deck comprising at least a head section, a seat section spaced from the head section, and a foot section spaced from the seat section, at least the head and foot sections each being movable relative to the frame, the foot section having an adjustable length,

a pivoting member coupled to the foot section and pivotable between a horizontal position and a non-horizontal position, and

a contracting member coupled to the foot section, arranged to extend away from the pivoting member in a longitudinal direction relative to the pivoting member, and independently slidable relative to the pivoting member to expand and contract the length of the foot section.

9. The bed of claim 8, wherein the contracting member is slidably connected to the pivoting member.

10. The bed of claim 8, wherein the pivoting member slidably receives the contracting member.

11. The bed of claim 8, wherein the contracting member is slidable toward the head section to reduce the length of the foot section.

12. The bed of claim 8, wherein the contracting member is slidable away from the head section, to extend the length of the foot section.

13. The bed of claim 12, wherein the contracting member is slidable toward the head section when the pivoting member is in the horizontal position.

14. The bed of claim 8, comprising a hinge coupling the pivoting section to another section of the deck located between the head section and the foot section.

15. A bed comprising:

a frame,

a deck configured to support a mattress in at least a horizontal position and a chair position, the deck comprising at least a head section and a foot section spaced from the head section, the head and foot sections each being movable relative to the frame, the foot section having at least a first length and a second length greater than the first length,

a pivoting member coupled to the foot section and being pivotable from a horizontal position to a non-horizontal position relative to the frame,

a contracting member coupled to the foot section, arranged to extend away from the pivoting member in a longitudinal direction relative to the pivoting member, and independently movable relative to the pivoting member,

at least one tab coupled to the contracting member, and

at least one channel located in the pivoting member, the at least one tab of the contracting member cooperating with the at least one channel of the pivoting member as the contracting member moves relative to the pivoting member to change the length of the foot section.

16. The bed of claim 15, wherein each tab of the contracting member is slidable in a channel of the pivoting member.

17. The bed of claim 15, wherein each channel of the pivoting member receives a tab of the contracting member.

18. The bed of claim 17, comprising a strut movably coupled to the foot section, wherein movement of the strut causes movement of the contracting member relative to the pivoting member to extend or retract the length of the foot section.

19. The bed of claim 18, wherein the strut comprises a first end coupled to the pivoting member.

20. The bed of claim 15, wherein the at least one tab is nearer the head section when the foot section has the first length and the at least one tab is farther from the head section when the foot section has the second length.
