ABSTRACT:
An inflatable life raft incorporates upper and lower canopies that are raised automatically above the upper or lower sides of the raft, respectively, depending on which side of the raft is facing upwardly when the raft is floating. The canopies each form a tent-like enclosure when raised to protect the raft occupants. The canopies are selectively raised by a generally vertically-oriented pillar slideably joined to the raft body, each end of the pillar being joined to corresponding upper and lower canopies. Preferably, the pillar is capable of floating to permit it to elevate above the raft body. The pillar may comprise an inflatable elongate member that slides disposed within an aperture within the floor. A skirt joins the pillar to the floor and provides a reversible waterproof seal between the pillar and the floor and limits the range of vertical travel of the pillar. One or more drain holes may be provided within the base of the skirt to allow the occupants to drain water from within the raft. A fabric cover protects the drain holes, and may be drawn up around the pillar after the water has been drained to prevent water from entering the raft. The raft may also incorporate but a single canopy on one side of the raft, for use in calmer waters where accidental inversion of the raft is unlikely.
