Open the CIPO recordAbstract From the Canadian patent
A pole support for use on decked surfaces consisting of planks with a gap between the planks is described. The pole support includes a base and at least one I-shaped retainer bar for quickly and easily attaching and releasing the base from the deck surface. The base includes a tubular sleeve for supporting the pole in a predetermined orientation with respect to the base. The pole support is useful for attaching articles such as umbrella tables or plant stands to a decked surface. The advantage is a simple, inexpensively constructed pole support which is not susceptible to corrosion and may be rapidly connected to or disconnected from a decked surface without the use of tools.

Why it's free to use
- Filed September 23, 1997 and granted November 12, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 23, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 23, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
