  • Patent number: 7896437
    Abstract: A rocker chair base assembly employs a set of unitary composite cam members to enable a user to engage in a rocking motion with a chair mounted over the assembly. Each cam member presents a rigid body with a set of laterally projecting sleeves. A first set of angle cross members serve to interconnect longitudinal rails on which the cam members reside, and a second set of angle cross members serve to interconnect adjacent cam members. Specifically, the laterally projecting sleeves of each cam member present a mating angle profile for slidably receiving therein and securely attaching with longitudinal end regions of the second set of angle cross members.

  • Patent number: 7628452
    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.

  • Patent number: 7252334
    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.
