<p>The device has a mobile system forming top and a roof of a caravan. Another mobile system forms, with a trailer, bottom of the caravan. Each system has two symmetrical covers (A1, A2) for the top, and two plates (G) i.e. bed mattress supports, for the bottom. The covers have slight size difference for being encased one in the other in a folded caravan position, and lifted/pivoted and separated to unfold the caravan. The plates pivot from vertical non-usage position to horizontal usage position. The association of the systems and a foldable luggage stand respond to the movement of the covers.</p> |
