ABSTRACT:
A unitary composite cam member is designed for integration into a rocker chair base assembly. In one arrangement, one cam member resides upon each longitudinal rail of the rocker chair base assembly. Each cam member includes a rigid body and one or more laterally projecting sleeves. The rigid body has an upper portion as well as a lower contact surface presenting an arcuate longitudinal profile. The shape of the contact surface enables rolling engagement on a longitudinal rail of a rocker chair base assembly. Each projecting sleeve extends laterally from the rigid body at a location generally near the top of the cam member. The projecting sleeves are designed to provide an attachment point for cross members of a rocker chair base assembly to accomplish coupling together of the cam members with each aligned upon one of the longitudinal rails. Additionally, the projecting sleeves are configured for securing rocker spring assemblies directly therewith to provide improved efficiencies in the fabrication of rocker chair base assemblies.
