  • Theft-proof non-rotating wheel cover with replaceable ornament
    Patent number: 5957542
    Abstract: A wheel cover provides a base for supporting the device within a central cavity in an automotive wheel. A cover plate is mounted in a bearing within the base and is weighted for non-rotational support on the wheel. A weight is supported within the cover plate so as to bias the cover plate in a preferred position. The weight is engaged within the cover plate by a negative draft angle on a peripheral lip of the cover plate so as to be asymmetrical with respect to the rotational axis of the wheel.
