Open the CIPO recordAbstract From the Canadian patent
A self-trimming shield for the gap between a hinged door heel and its casing, includes a unitary strip of length approximately equal to the height of the door and made up of a sequentially arrayed plurality of elongated parallel panels. Opposite end panels of the plurality are attached, respectively to the door and casing on the side opposite the hinge, while inner panels of said plurality are articulably connected with the end panels and with each other in such manner that, when the door is closed, the panels automatically fold to lie in close proximity to the door so that the shield appears to be an integral part of the door trim.

Why it's free to use
- Filed March 17, 1993 and granted August 3, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 17, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 17, 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.
