ABSTRACT:
The present invention relates to a furniture support structure, and more particularly to a base for supporting a rocking chair. The rocker base has a lower frame, an upper frame, and a plurality of cams. The lower frame has a plurality of lower U-shaped cross members connected to a plurality of side rails, and a plurality of lower spring mounts extending between the lower cross members and connected to the side rails. The upper frame has a plurality of upper U-shaped cross members connected to a plurality of L-shaped side brackets, and a plurality of upper spring mounts extending between the upper cross members and connected to the L-shaped side brackets. The plurality of cams have an arcuate lower surface positioned against the side rails and a flat upper surface attached to the L-shaped side brackets. The cams are compressibly loaded between the side rails and the L-shaped side brackets. The upper spring mounts are inwardly offset from a vertical portion of the L-shaped side brackets to avoid all fasteners joining the cams to the L-shaped side brackets.
