Each of the holding trenches is made to have a slot narrower than a middle room thereof, and the lamps have a diameter bigger than width of the slot so as not to fall down when held in the trenches. Thus the, lamps are hidden in the holding trenches to not badly affect appearance of the tent. And, light emitting diodes can be used as the lamps to help make the tent attractive.

Why it's free to use
- Filed September 12, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 12, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 12, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
