Abstract
A rocking chair having a chair frame (12) operable for providing rocking motion relative to a stationary base (14) is provided. The rocking chair generally comprises a chair frame (12) and a stationary base (14) coupled together by a rocker spring assembly (30). The rocker spring assembly (30) includes an upper and lower bracket (32, 34) having a pair of springs (36, 37) and means (50) for suppressing the noise generated by the springs. The rocker spring assembly further includes means (40) for limiting the rocking movement of the chair frame disposed between the upper and lower bracket of the rocker spring assembly. The present invention further includes means for suppressing the noise generated by other spring elements associated with a reclining or rocking/reclining chair.
Claims
1. A rocking chair comprising: a base; a chair frame supported on said base for rocking movement relative to said base; a rocker spring assembly coupling said base and said chair frame, said rocker spring assembly having an upper bracket secured to said chair frame, a lower bracket secured to said base, spring means disposed between and secured to said upper and lower brackets for biasing said chair frame in an upright, neutral position and for enabling a seat occupant to rock forwardly and rearwardly, and a first and second limit rod disposed between said upper and lower brackets, each of said first and second limit rods having a shaft portion and a stop member disposed at each end of said shaft portion, said upper and lower brackets having apertures formed therethrough for receiving said shaft portion of each of said first and second limit rods such that said stop members are engagable with said upper and lower brackets to define a range of rocking movement; and means for suppressing noise generated by said spring means as said chair frame is rocked.
2. The rocking chair of Claim 1 wherein said spring means comprises a coil spring having an inner diameter and said means for suppressing noise comprises a dampening insert disposed within said coil spring.
3. The rocking chair of Claim 2 wherein said dampening insert comprises a rectangular insert having a width greater than said inner diameter of said coil spring such that said rectangular insert engages a plurality of coils of said coil spring to suppress noise generated thereby.
4. The rocking chair of Claim 2 wherein said dampening insert comprises pressed felt. 1 6
5. The rocking chair of Claim 1 wherein said apertures formed in said upper and lower brackets are sufficiently oversized to allow said upper bracket to freely rotate and translate relative to said lower bracket as said chair is rocked within said range of rocking movement.
6. The rocking chair of Claim 1 wherein said rocker spring assembly further comprises locator means disposed on at least one of said first and second limit rods for axially locating said at least one of said first and second limit rods relative to said rocker spring assembly.
7. The rocking chair of Claim 6 wherein said locator means comprises an O-ring releasably retained on said shaft portion of said at least one of said first and second limit rods.
8. A rocking/reclining chair comprising: a base; a chair frame supported on said base for rocking movement relative to said base; a rocker spring assembly coupling said base and said chair frame, said rocker spring assembly having an upper bracket secured to said chair frame, a lower bracket secured to said base, spring means disposed between and secured to said upper and lower brackets for biasing said chair frame in an upright, neutral position and for enabling a seat occupant to rock forwardly and rearwardly, and a first limit rod disposed between said upper and lower brackets, said first limit rod having a shaft portion and a stop member disposed at each end of said shaft portion, said upper and lower brackets having apertures formed therethrough for receiving said shaft portion of said first limit rod such that said stop members are with engagable said upper and lower brackets to define a range of rocking movement; a seat assembly disposed within and suspended from said chair frame, said seat assembly including a seat frame, a seat back and swing link means pivotally interconnecting said seat back and said seat frame for permitting reclining movement of said seat assembly with respect to said chair frame between an upright position and a reclined position; 1 7
a leg rest assembly disposed within and suspended from said chair frame, said leg rest assembly positionable between a retracted position and a protracted position; an actuation mechanism cooperating with said leg rest assembly to protract and retract said leg rest assembly, said actuation mechanism having actuation spring means for providing mechanical assistance in the protraction and retraction of said leg rest assembly; means for suppressing noise generated by said rocker spring means and said actuation spring means as said chair is operated.
9. The rocking/reclining chair of Claim 8 wherein said rocker spring means comprises a rocker coil spring having an inner diameter and said actuation spring means comprises an actuation coil spring having an inner diameter, and said means for noise suppression comprises first dampening insert disposed within said rocker coil spring and a second dampening insert disposed within said actuation coil spring.
10. The rocking/reclining chair of Claim 8 wherein said rocker spring assembly further comprises a second limit rod disposed between said upper and lower brackets, said second limit rod having a shaft portion and a stop member disposed at each end of said shaft portion, said upper and lower brackets having apertures formed therethrough for receiving said shaft portion of said second limit rod such that said stop members are engagable said upper and lower brackets to define a range of rocking movement.
11. The rocking/reclining chair of Claim 8 wherein said rocker spring assembly further comprises locator means disposed on said limit rod for axially locating said limit rod relative to said rocker spring assembly.
12. The rocking chair of Claim 11 wherein said locator means comprises an O-ring releasably retained on said shaft portion of said first limit rod. 1 8
13. The rocking chair of Claim 8 wherein said apertures formed in said upper and lower brackets are sufficiently oversized to allow said upper bracket to freely rotate and translate relative to said lower bracket as said chair is rocked within said range of rocking movement.
14. A rocking/reclining chair comprising: a base; a chair frame supported on said base for rocking movement relative to said base; a rocker spring assembly coupling said base and said chair frame, said rocker spring assembly having an upper bracket secured to said chair frame, a lower bracket secured to said base, spring means disposed between and secured to said upper and lower brackets for biasing said chair frame in an upright, neutral position and for enabling a seat occupant to rock forwardly and rearwardly, a first and second limit rod disposed between said upper and lower brackets, each limit rod having a shaft portion and a stop member disposed at each end of said shaft portion, said upper and lower brackets having apertures formed therethrough for receiving said shaft portion of said first limit rod such that said stop members are engagable with said upper and lower brackets to define a range of rocking movement; a seat assembly disposed within and suspended from said chair frame, said seat assembly including a seat frame, a seat back and swing link means pivotally interconnecting said seat back and said seat frame for permitting reclining movement of said seat assembly with respect to said chair frame between an upright position and a reclined position; a leg rest assembly disposed within and suspended from said chair frame, said leg rest assembly positionable between a retracted position and a protracted position; an actuation mechanism cooperating with said leg rest assembly to protract and retract said leg rest assembly, said actuation mechanism having actuation spring means for providing mechanical assistance in the protraction and retraction of said leg rest assembly. 1 9
