Abstract

A life raft may include a base comprising a first side and a second side, and a self-supporting, collapsible spring canopy. The canopy may include a spring wire frame, a first panel circumscribed by the spring wire frame, and a second panel circumscribed by the spring wire frame.

First claim

What is claimed is:

1. A life raft arrangement, comprising:
a life raft comprising a base comprising a first side and a second side; and
a canopy comprising a spring wire frame forming a first loop and a second loop, the first loop of the spring wire frame circumscribing a first panel of the canopy and the second loop of the spring wire frame circumscribing a second panel of the canopy, wherein the canopy is self-supported via the spring wire frame; and
the canopy is configured to be removably coupled to either of the first side of the base and the second side of the base such that the life raft is reversible.

2. The life raft arrangement of claim 1 , wherein the base comprises an inflatable border tube defining an inflatable volume.

3. The life raft arrangement of claim 1 , wherein the spring wire frame intersects itself at an apex of the canopy.

4. The life raft arrangement of claim 3 , wherein the spring wire frame is formed into a figure eight.

5. The life raft arrangement of claim 1 , wherein the spring wire frame is disposed in a sleeve.

6. The life raft arrangement of claim 1 , wherein the canopy further comprises a third panel extending between the first loop and the second loop.

7. The life raft arrangement of claim 2 , wherein the canopy is removably coupled to the inflatable border tube.

8. The life raft arrangement of claim 1 , further comprising a storage pouch configured to contain the canopy separate from the life raft.

9. The life raft arrangement of claim 8 , wherein the storage pouch is configured for use as a receptacle for removing water from the life raft when the canopy is removed from the storage pouch.

10. The life raft arrangement of claim 1 , wherein the spring wire frame is retained within a frame retaining sleeve without being connected thereto.

11. The life raft arrangement of claim 1 , wherein the canopy is configured to be removably coupled to the base via a snap buckle.

12. The life raft arrangement of claim 1 , wherein the canopy is moveable between a first configuration where the canopy is disposed on the first side of the base and a second configuration where the canopy is disposed on the side of the base.

13. A life raft arrangement, comprising:
a life raft comprising a base comprising a first side and a second side, and an inflatable border tube defining an inflatable volume; and
a self-supporting, collapsible spring canopy, comprising:
a spring wire frame;
a first panel circumscribed by the spring wire frame; and
a second panel circumscribed by the spring wire frame,

wherein the self-supporting, collapsible spring canopy is configured to be removably coupled to the inflatable border tube at either of the first side of the base and the second side of the base such that the life raft is reversible.

14. The life raft arrangement of claim 13 , wherein the spring wire frame intersects itself at an apex of the self-supporting, collapsible spring canopy.

15. The life raft arrangement of claim 13 , wherein the spring wire frame is formed into a figure eight.

16. The life raft arrangement of claim 13 , wherein the spring wire frame is disposed in a sleeve.

17. The life raft arrangement of claim 13 , wherein the self-supporting, collapsible spring canopy further comprises a third panel extending between the first panel and the second panel.

18. The life raft arrangement of claim 13 , further comprising a storage pouch configured to contain the self-supporting, collapsible spring canopy separate from the base, wherein the storage pouch is configured for use as a receptacle for removing water from a life raft.
