ABSTRACT:
A rocker block for use in a rocking-type chair having a base assembly and an upholstered chair frame. The rocker block is adapted for mounting to a lateral side of the chair frame's lower frame structure and has an arcuate surface engageable with the base assembly for enabling rocking movement of the chair frame relative to the base assembly. The rocker block is a molded plastic component having an alignment arrangement formed thereon for engaging a portion of the lower frame structure. In addition, a first set of apertures are formed in the rocker block for receiving suitable fasteners so as to rigidly secure the plastic rocker block to the lower frame structure. Likewise, a second set of apertures are provided for receiving suitable fasteners to couple a rocker spring mechanism to the plastic rocker block. The plastic rocker block overcomes disadvantages associated with wooden components and provides the requisite rigidity and load-bearing strength to promote enhanced rocking action.
