The swivel hinge includes a swivel element with apertures and a base element with a swivel shaft which is journaled for rotation within the apertures. The apertures include radially inwardly extending fingers which position the swivel shaft and are formed as molding gates for molding windows which are provided in common for initially molding the base element and the swivel member as a single integral piece. Subsequent rotation breaks the molding gates and the vestiges form the fingers.

Why it's free to use
- Filed January 25, 2000 and granted November 25, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 25, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 25, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
