The ROTATING ORNAMENT is an operable toy designed to keep an ornament rotating and oscillating about a threaded rod formed in the shape of a ring. With the ring held vertically, the ornament is maintained in mid-position by continually turning the ring. Other inventions of this type are so constructed that they can only be operated by hand, whereas this present invention can also be handcranked, motorized, or operated by wheeling the toy along the floor.

Why it's free to use
- Filed March 30, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 30, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 30, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
