  • Patent number: 7216516
    Abstract: A wobble joint particularly useful for supporting a wash plate in a wash basket of an automatic washing appliance includes inner and outer races formed with mating part-spherical surfaces having common centers of curvature about a longitudinal axis of the joint. Anti-rotation structure acts between the inner and outer races to prevent relative rotation of the races about the longitudinal axis, and cooperates with the part-spherical surfaces to restrict the races to two degrees of tilting movement about respective tilt axes disposed perpendicular to the longitudinal axis and to one another, such that one of the races is thereby supported for wobbling movement relative to the other of the races. In a washing appliance application, the wash plate is fixed to the outer race and wobbles relative to the inner race.
