  • Patent number: 7278245
    Abstract: A radial-hinge mechanism includes one or more elongated members arranged and interconnected into a unique, geometry-based, closed-loop assembly often resembling a multi-point star when in its fully-closed mode. The mechanism's signature function is its variable nature of pivoting open from a centralized hinge-core as its substantially circular inner-aperture concurrently contracts in its own circular dimensions. Additionally, the mechanism has a natural susceptibility to spring-biasing techniques to further modify its versatility and performance.

  • Patent number: 4743068
    Abstract: An article of knock-down furniture that can be easily assembled by an end-user comprises a plurality of pieces and contact joint arrangements that prevent unwanted separation of the pieces, while permitting the pieces to rotate and flex relative to each other. The contact joint arrangements also have lateral flexibility to permit the pieces to be coupled and shaped into a contour. The contact joint arrangement has a flexible tube that extends through a continuous bore through each of the pieces. A threaded fastener is threaded into each end of the tube and tightened against the end surface of the end pieces in order to place the tube in tension. The pieces are, consequently, held in longitudinal compression between the two threaded fasteners, while remaining free to rotate about the longitudinal axis of the tube. In one embodiment, a screw assembly is threaded into the tube through a hole or notch cut near one end of the tube.
