<p>An inflatable raft 1 comprises an outer skin 3 and a generally toroidal inflatable chamber 5. A one-way valve 9 is provided to allow gas to be inputted into the chamber 5. The raft 1 is placed within a cylindrical enclosure 11, the enclosure having a storage section 13 and a lid 15 attached to the storage section by a spring-loaded hinge 17. The free end is accessible from the outside of the enclosure 11. Once the raft 1 is inside the enclosure 11, the lied 15 is closed. At the place of intended use, air is pumped into the chamber 5 by means of the free end of the valve 9, causing the chamber to inflate. Due to appropriate dimensioning of the enclosure 11, the inflation of the chamber, and so the raft 1, is restricted and the air in the chamber 5 becomes pressurized. When the raft 1 is to be deployed, the lid 15 of the enclosure 11 is opened, and the raft removed from the enclosure, the pressurized air causing the raft 1 to inflate, or expand, to its normal operating condition.</p> |
