Abstract

A rocking chair has a frame with first and second leg hubs. The first and second leg hubs each have leg member openings for leg members. The frame also has first and second seat hubs. The seat hubs have seat member openings for seat members. The first and second leg hubs form a leg support frame and the first and second seat hubs form a seat support frame. The leg support frame is rotatably connected to the seat support frame with a biasing member extending therebetween configured to urge against rotation in either direction. The leg members detachably connect to the first and second leg hubs at the leg member openings. The seat members detachably connect to the seat hubs at the seat member openings. Seat connector pockets are provided on the corners of the seat portion to allow the seat portion to detachably connect to the seat members.

First claim

What is claimed is:

1. A rocking chair comprising:
a frame comprising:
first and second leg hubs, the first leg hub and the second leg hub each having leg member openings adapted and configured to receive leg members, the first and second leg hubs comprising a leg support frame;
first and second seat hubs, the first seat hub and the second seat hub each having seat member openings adapted and configured to receive seat members, the first and second seat hubs comprising a seat support frame;
leg members adapted and configured to detachably connect to the first and second leg hubs at the leg hub leg member openings;
seat members adapted and configured to detachably connect to the seat hubs at the seat hub seat member openings;
the leg support frame being rotatably connected to the seat support frame with a biasing member extending therebetween configured to urge against rotation in either direction; and

a seat adapted and configured to detachably connect to the seat members.

2. The rocking chair of claim 1 further comprising an elastic band extending between at least one leg member and its respective hub.

3. The rocking chair of claim 1 further comprising an elastic band extending between at least one seat member and its respective hub.

4. The rocking chair of claim 1 further comprising a center support member rotatably connected to the first and second leg hubs.

5. The rocking chair of claim 4 wherein the seat hubs rotate with the center support member.

6. The rocking chair of claim 4 wherein the leg hubs have a depending portion engaged with the biasing member.

7. The rocking chair of claim 4 wherein the center support member has an extension portion engaged with the biasing member.

8. The rocking chair of claim 7 wherein the extension portion has a seat member opening adapted and configured to receive a seat member.

9. The rocking chair of claim 7 wherein the extension portion is axially inward of the leg hubs.

10. The rocking chair of claim 7 wherein the seat hubs are axially outward of the leg hubs.

11. The rocking chair of claim 4 wherein the biasing member comprises a coil spring.

12. The rocking chair of claim 11 wherein the rotation of the leg support frame relative to the seat support frame is limited by expansion of the coil spring in one direction and compression of the coil spring in an opposite direction.

13. The rocking chair of claim 1 further comprising a center support member operatively connected to the first and second leg hubs.

14. The rocking chair of claim 13 further comprising a rotating sleeve operatively connected to the first and second seat hubs.

15. The rocking chair of claim 14 wherein the rotating sleeve is adapted and configured to rotate about the center support member.

16. The rocking chair of claim 15 wherein the biasing member operatively engages the center support member and operatively engages the seat hub.

17. The rocking chair of claim 13 wherein the biasing member comprises a torsion spring.

18. The rocking chair of claim 17 wherein the torsion spring has a straight portion that engages the seat hub.

19. The rocking chair of claim 17 wherein the torsion spring has a portion that engages a protrusion on the center support member.

20. The rocking chair of claim 17 wherein the torsion spring has a hooked portion that engages a protrusion on the center support member.

21. The rocking chair of claim 13 wherein at least one of the first and second seat hubs and at least one of the first and second leg hubs that adjoins with the at least one of the first and second seat hubs has cooperating geometry that limits relative rotation therebetween.

22. The rocking chair of claim 21 wherein the cooperating geometry comprises a slot formed on one of the leg hubs and seat hubs and a protuberance formed on the other of the leg hubs and seat hubs.

23. The rocking chair of claim 22 wherein the slot is dimensionally larger than the protuberance.

24. The rocking chair of claim 1 wherein the leg members project from their respective hub leg member openings at an angle less than 90 degrees relative to each other.

25. The rocking chair of claim 1 wherein the seat members project from their seat hub member openings at an obtuse angle relative to each other.

26. A method comprising:
accessing a rocking chair, wherein the rocking chair has a frame comprising:
first and second leg hubs, the first leg hub and the second leg hub each having leg member openings adapted and configured to receive leg members, the first and second leg hubs comprising a leg support frame;
first and second seat hubs, the first seat hub and the second seat hub each having seat member openings adapted and configured to receive seat members, the first and second seat hubs comprising a seat support frame;
leg members adapted and configured to detachably connect to the first and second leg hubs at the leg hub leg member openings;
seat members adapted and configured to detachably connect to the seat hubs at the seat hub seat member openings;
the leg support frame being rotatably connected to the seat support frame with a biasing member extending therebetween configured to urge against rotation in either direction; and

a seat adapted and configured to detachably connect to the seat members; and
the method further comprising:
inserting the leg members in the leg hub leg member openings;
inserting the seat members in the seat hub seat member openings; and
attaching the seat to the seat members.

27. The method of claim 26 wherein the step of inserting the leg members into the leg hub leg member openings further comprises manipulating an elastic band extending between at least one leg member and its respective hub.

28. The method of claim 26 wherein the step of inserting the seat members into the seat hub seat member openings further comprises manipulating an elastic band extending between at least one seat member and its respective hub.

29. The method of claim 26 wherein the seat support frame comprises a center support member rotatably connected to the first and second leg hubs and the center support member has an extension portion engaged with the biasing member; and
the method further comprises inserting seat members into seat member openings on the center support member extension.

30. The method of claim 29 further comprises manipulating an elastic band extending between the seat member and its respective extension portion.
