A hinged electrical outlet cover biased rotatably about the hinge axis by an M-shaped spring. In one arrangement, the cover is self-closing throughout its entire range of movement between fully open and fully closed positions. In another arrangement, the cover is positively held open in its fully open position and is self-closing over a limited range of movement from its fully closed position to an intermediate open position. The cover and a support member on which it is hinged are designed for quick snap assembly without requiring the use of special tools or separate fasteners.

Why it's free to use
- Filed October 29, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 29, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 29, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
