Open the CIPO recordAbstract From the Canadian patent
A wheel cover provides a base (18) for supporting the device within a central cavity (18A) in an automotive wheel (18). A cover plate (10) is mounted in a bearing (3) within the base (8) and is weighted for non-rotational support on the wheel (18). A weight (9) is supported within the cover plate (10) so as to bias the cover plate (10) in a preferred position. The weight (9) is engaged within the cover plate (10) by a negative draft angle on a peripheral lip (20) of the cover plate (10) so as to be asymmetrical with respect to the rotational axis (18A) of the wheel (18).

Why it's free to use
- Filed May 30, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 30, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 30, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
