Abstract

A furniture member may include a base frame, a seat bottom and an ottoman assembly. The seat bottom is attached to the base frame and defines a seating surface. The ottoman assembly may include a drive assembly that moves an ottoman platform relative to the seat bottom and the base frame among a retracted position, an extended position and a raised position. The ottoman platform includes a support surface that faces upward and away from a ground surface in the retracted, extended and raised positions. The ottoman platform is disposed beneath the seating surface in the retracted position and moves linearly in a horizontal direction from the retracted position to the extended position. The ottoman platform moves linearly in a vertically upward direction from the extended position to the raised position.

First claim

What is claimed is:

1. A furniture member comprising:
a base frame;
a seat bottom attached to the base frame and defining a seating surface;
an ottoman assembly including a drive assembly that moves an ottoman platform relative to the seat bottom and the base frame among a retracted position, an extended position and a raised position, the ottoman platform including a support surface that faces upward and away from a ground surface in the retracted, extended and raised positions,
wherein the ottoman platform is disposed beneath the seating surface in the retracted position and moves linearly in a horizontal direction from the retracted position to the extended position, and wherein the ottoman platform moves linearly in a vertically upward direction from the extended position to the raised position;
wherein the furniture member further comprises:
a shroud panel attached to the ottoman platform and movable with the ottoman platform between a folded condition and an unfurled condition as the ottoman platform moves vertically between the extended position and the raised position, wherein the shroud panel shields the drive assembly from a user's view when the ottoman platform is in the raised position; and
an elongated elastic strip fixed at one end to the shroud panel and fixed at the other end to the upward-facing support surface of the ottoman platform, wherein movement of the ottoman platform toward the raised position resiliently stretches the elastic strip such that movement of the ottoman platform downward away from the raised position allows the elastic strip to pull a portion of the shroud panel underneath the ottoman platform.

2. The furniture member of claim 1 , wherein the seat bottom is stationary relative to the base frame as the ottoman platform moves among the retracted, extended and raised positions.

3. The furniture member of claim 1 , wherein the drive assembly includes a first motor-driven actuator driving the ottoman platform between the retracted and extended positions and a second motor-driven actuator driving the ottoman platform between the extended and raised positions.

4. The furniture member of claim 3 , further comprising:
a third motor-driven actuator drivingly connected to the seat bottom and driving the seat bottom horizontally relative to the base frame; and
a seatback pivotably attached to the seat bottom and the base frame such that movement of the seat bottom relative to the base frame causes corresponding rotation of the seatback relative to the seat bottom and the base frame.

5. The furniture member of claim 4 , wherein operation of the first and second motor-driven actuators is sequenced together and the third motor-driven actuator is operable independently of the first and second motor-driven actuators.

6. The furniture member of claim 4 , wherein the ottoman platform is movable horizontally relative to the base frame from the raised position to an ottoman sleeper position in response to movement of the seat bottom horizontally relative to the base frame.

7. The furniture member of claim 6 , wherein the seatback includes a first side that faces a seatback cushion when the seatback is in an upright position, wherein the seatback is rotated into a seatback sleeper position as the ottoman platform moves into the ottoman sleeper position, and wherein the first side of the seatback faces vertically upward in the seatback sleeper position such that the seatback cushion cooperates with an ottoman cushion and a seat bottom cushion to define a horizontal sleep surface.

8. The furniture member of claim 7 , wherein a person can remain seated on the seat bottom with the person's back contacting the seatback cushion throughout the entire range of motion of the seatback and the ottoman assembly.

9. The furniture member of claim 1 , wherein the ottoman assembly includes an ottoman frame supporting the ottoman platform, an extension mechanism attached to the ottoman frame and the base frame and moving the ottoman platform between the retracted and extended positions, and a lift mechanism attached to the ottoman frame and the ottoman platform and moving the ottoman platform between the extended and raised positions.

10. The furniture member of claim 9 , wherein the ottoman frame includes a plurality of rollers mounted thereto that roll along the ground surface as the ottoman assembly moves between the extended and retracted positions.

11. The furniture member of claim 9 , wherein the lift mechanism includes a first scissor linkage.

12. The furniture member of claim 11 , wherein the extension mechanism includes a second scissor linkage that operates independently of the first scissor linkage.

13. The furniture member of claim 9 , wherein the extension mechanism includes a telescoping member attached to the base frame at one end and attached to the ottoman frame at another end.

14. The furniture member of claim 9 , wherein the seat bottom includes a pair of first track members, and the ottoman frame includes a pair of second track members that slidingly engage the first track members.

15. The furniture member of claim 14 , wherein the first track members slide along the second track members in a linear path.

16. The furniture member of claim 15 , wherein the base frame includes a pair of third track members, wherein the seat bottom slidably engages the third track members, and wherein the third track members extend in a linear direction.

17. The furniture member of claim 1 , wherein an upward-facing surface of a seat bottom cushion is substantially level with an upward-facing surface of an ottoman cushion of the ottoman platform when the ottoman platform is in the raised position.

18. The furniture member of claim 1 , further comprising a seatback that is fixed relative to the seat bottom and the base frame.

19. The furniture member of claim 1 , wherein the shroud panel is pulled taut in the unfurled condition.

20. The furniture member of claim 1 , wherein the ottoman platform includes a slot through which the elastic strip extends.

21. The furniture member of claim 20 , wherein an upper edge of the shroud panel is fixed to a side of the ottoman platform, and a lower edge of the shroud panel is fixed to an ottoman frame member supporting the drive assembly.

22. The furniture member of claim 21 , wherein the elastic strip is attached to a seam of the shroud panel that is disposed between the upper and lower edges.
