  • Patent number: 7210746
    Abstract: A wheel mountable car wheel cover provides a design element that is visible while the wheel is rotated. A circular rotation case has a liquid filled floating chamber. A bearing for mounting the rotation case to a wheel is provided on the rotation case. A disk-type design plate is disposed floating in the floating chamber, and a weight disposed on a lower side of the design plate causes the design plate to remain in a stable, upright position despite rotation of the rotation case. A surface of the rotation case is transparent such that a surface of the design plate is visible through the surface of the rotation case. Thus, a picture or logo disposed on the surface of the design plate is visible through the surface of the rotation case. In one embodiment, the rotation case is disposed within a protection case which is mountable on a wheel.
