Abstract

A furniture member such as a rocking chair includes a chair frame operable for rocking motion relative to a stationary base. The chair frame and stationary base are coupled together by a rocker spring assembly positioned on each side of the frame/base. The rocker spring assembly includes upper and lower brackets and a single coiled spring connected to both brackets. A displacement limiting device is positioned within an inner cavity of the coiled spring to limit the rocking movement of the chair frame.

a shaft having opposed ends; and a bulbous head created at each of the opposed ends;
wherein the shaft is movably received within an aperture in each of the first and second brackets, the displacement limiting device being operable to limit a total displacement between the first and second brackets when the bulbous heads contact the first and second brackets.
2. The rocker spring assembly of Claim 1, wherein each of the first and second brackets further comprise a first bracket portion and a second bracket portion, the second bracket portion operable to connectably receive the coil spring.
3. The rocker spring assembly of Claim 2, further comprising a hook-shaped member extending from the second bracket portion and engageable with the coil spring.
4. A rocker spring assembly for a rocking furniture member, comprising:
a first bracket;
a second bracket arranged in opposed relationship to the first bracket;
a biasing element connected between the first and second brackets, the biasing element including an open inner cavity;

each of the first and second brackets further include a first bracket portion and a second bracket portion, the second bracket portion operable to connectably receive the biasing element;
a displacement limiting device disposed through the inner cavity of the biasing element, the displacement limiting device including:
a shaft having opposed ends; and a bulbous head created at each of the opposed ends;
a hook-shaped member extending from the second bracket portion and engageable with the biasing element; and at least one raised element created on the second bracket portion and oriented with respect to the hook-shaped member to positively engage the biasing element between the hook-shaped member and the raised element;
wherein the shaft is movably received within an aperture in each of the first and second brackets, the displacement limiting device being operable to limit a total displacement between the first and second brackets when the bulbous heads contact the first and second brackets.
5. The rocker spring assembly of Claim 1, wherein each of the first and second brackets further comprise a plurality of alignment apertures.
6. The rocker spring assembly of Claim 1, wherein the second bracket comprises a duplicate of the first bracket.
7. The rocker spring assembly of Claim 1, wherein the coil spring is reversibly positionable between the first and second brackets.
8. The rocker spring assembly of Claim 1, wherein a longitudinal axis of the displacement limiting device is offset from a coil spring longitudinal axis.
9. A rocking furniture member, comprising:
a base;
a chair frame supported on the base for rocking movement relative to the base, the chair frame including first and second side members;

a first rocker spring assembly directly coupling the first side member and the base;
a second rocker spring assembly directly coupling the second side member and the base;
each of the first and second rocker spring assemblies including:
a first bracket secured to the chair frame;
a second bracket secured to the base; and a single coil spring disposed between and secured to the upper and lower brackets for biasing the chair frame in an upright, neutral position and for enabling a furniture member occupant to rock forwardly and rearwardly.
10. The rocking furniture member of Claim 9, further comprising a limit device disposed through an inner cavity of the coil spring.
11. The rocking furniture member of Claim 10, wherein the limit device further comprises:
a shaft portion; and a stop member disposed at each end of the shaft portion;
wherein the first and second brackets each include an aperture formed therethrough for receiving the shaft portion of the limit device, the stop members being engagable with the first and second brackets to define a range of rocking movement of the furniture member.
12. canceled
13. The rocking furniture member of claim 10, comprising a predetermined length of the limit device selectable to limit a total displacement of the coil spring.
14. The rocking furniture member of claim 10, comprising a position of the limit device within the inner cavity operable to divide the range of rocking movement substantially equally between a forward and a backward rocking movement.
15. The rocking furniture member of claim 10, comprising a position of the limit device within the inner cavity operable to unequally divide the range of rocking movement between a forward and a backward rocking movement.
16. The rocking furniture member of claim 11, comprising a size of the aperture formed in the first and second brackets operable to allow the first bracket to freely rotate and translate relative to the second bracket as the furniture member is rocked within the range of rocking movement.
17. A rocking/reclining chair, comprising:
a base;
a chair frame supported on the base for rocking movement relative to the base;
a rocker spring assembly coupling the base and the chair frame, the rocker spring assembly including:
a first bracket secured to the chair frame;
a second bracket secured to the base;
a single coil spring disposed between and secured to the first and second brackets for biasing the chair frame in an upright, neutral position and for enabling an occupant to rock forwardly and rearwardly; and a limit member disposed between the first and second brackets and within a cavity of the single coil spring, the limit member having a shaft portion and a stop member disposed at each end of the shaft portion, the limit member being operable to limit a total displacement of the rocker spring assembly;
and a leg rest assembly disposed within and suspended from the chair frame, the leg rest assembly positionable between a retracted position and an extended position.
18. The rocking/reclining chair of Claim 17, further comprising an aperture formed through the first and second brackets for receiving the shaft portion of the limit member, the stop members being engagable with the first and second brackets to define a range of rocking movement.
19. The rocking chair of claim 18, wherein the apertures created in the first and second brackets are sized to allow the first bracket to freely rotate and translate relative to the second bracket as the chair is rocked within the range of rocking movement.
20. canceled
21. A method for controlling a rocking motion of a rocking chair, the chair having a base, a chair frame supported from the base and a rocker spring assembly connecting the base to the chair frame, the rocker spring assembly having first and second brackets, the method comprising:
interconnecting the first and second brackets with a single coil spring to bias the chair frame in an upright, neutral position and to enable a seat occupant to rock forwardly and rearwardly;
slidably interposing a displacement limiting device between the first and second brackets and within a cavity of the single coil spring; and creating radially extending opposed ends of the displacement limiting device engageable with the upper and lower brackets operable to limit a range of rocking movement of the rocking chair.
22. The method of Claim 21, further comprising creating apertures in both the first and second brackets to movably receive the displacement limiting device.
23. The method of Claim 21, further comprising:
attaching the first bracket of the rocker spring assembly to the chair frame; and connecting the second bracket of the rocker spring assembly to the base.
24. The method of Claim 21, further comprising extending a hook-shaped element from the rocker spring assembly operable to mechanically engage the single coil spring.
