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.
Claims12
A wheel cover device for an automotive wheel having an axis of rotation, the device comprising:
- a mounting base having a means for wheel engagement and a means for bearing engagement, the mounting base being fixedly supported within a mounting cavity formed on the axis of rotation of the automotive wheel by the wheel engagement means;
- a bearing means engaged within the bearing engagement means of the mounting base and positioned for rotation on the axis of rotation;
- a cover plate positioned adjacent to the bearing means, the cover plate providing a cover plate mounting hole positioned on the axis of rotation and a means for weighting, the weighting means being asymmetrical to the axis of rotation and supported in the cover plate by a peripherally enclosing side lip, the side lip having a negative draft angle thereby capturing the weighting means within the cover plate;
- a means for rotational engagement between the cover plate and the bearing means so that with the automotive wheel and the mounting base in rotation, the cover plate is biased by the weighting means to maintain a non-rotating position with the weighting means urging the cover plate toward a preferred attitude as the wheel rotates;
- the mounting cavity providing a circular cavity sidewall and an annular cavity lip extending inwardly therefrom and defining an aperture of the mounting cavity, the mounting base providing an outer circular base wall engagable within the cavity, and an annular base lip extending outwardly into contact with an outwardly facing surface of the cavity lip thereby sealing the mounting cavity aperture.

A combination comprising:
- an automotive wheel having an axis of rotation;
- and
- a wheel cover device, the device providing;
- a mounting base having a means for wheel engagement and a means for bearing engagement, the mounting base being fixedly supported within a mounting cavity formed on the axis of rotation of the automotive wheel by the wheel engagement means;
- a bearing means engaged within the bearing engagement means of the mounting base and positioned for rotation on the axis of rotation;
- a cover plate positioned adjacent to the bearing means, the cover plate providing a cover plate mounting hole positioned on the axis of rotation and a means for weighting, the weighting means being asymmetrical to the axis of rotation and supported in the cover plate by a peripherally enclosing side lip, the side lip having a negative draft angle thereby capturing the weighting means within the cover plate;
- a means for rotational engagement between the cover plate and the bearing means so that with the automotive wheel and the mounting base in rotation, the cover plate is biased by the weighting means to maintain a non-rotating position with the weighting means urging the cover plate toward a preferred attitude as the wheel rotates;
- the mounting cavity providing a circular cavity sidewall and an annular cavity lip extending inwardly therefrom and defining an aperture of the mounting cavity, the mounting base providing an outer circular base wall engagable within the cavity, and an annular base lip extending outwardly into contact with an outwardly facing surface of the cavity lip thereby sealing the mounting cavity aperture.
