A sectional shelter is made of a set of panels of plastic material arranged side by side, along with a plastic roof cap. The panels are coupled by ribs projecting from one edge portion of each panel and a channel along the other edge portion. Retainers are pivotally mounted on the inside of the wall adjacent the channeled edge portion so that the edge portion carrying the ribs may be captured between the inside wall of the panel and the retainer. The shelter has curved and straight panels so that it may have variousconfigurations. Door and window openings are formed in the wall panels and are closed by doors and windows fastened on the panels.

Why it's free to use
- Filed November 15, 1993 and granted December 30, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 15, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 15, 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.
