Inflatable structure
The present invention relates to an inflatable structure comprising an inflatable frame and a single inflation valve. The inflatable frame has at least two chambers in fluid communication with at least one other chamber through a check valve, whereby the chambers are inflated through the inflation valve.
1. An inflatable structure comprising an inflatable frame and a single inflation valve, said inflatable frame having at least two chambers, each one of said chambers being in fluid communication with at least one other of said chambers through a check valve, whereby said chambers are inflated through said single inflation valve and wherein said check valves are located inside said inflatable frame.
2. An inflatable structure as defined in claim 1 further comprising an inflatable supporting surface in fluid communication with at least one said chamber.
3. An inflatable structure as defined in claim 2 further comprising a deck check valve between said supporting structure and one said chamber.
4. An inflatable structure as defined in claim 3 wherein each one of said chambers is in fluid communication with at least one adjacent said chamber.
5. An inflatable structure as defined in claim 4 wherein each one of said chambers and said supporting surface has a deflation valve.
6. An inflatable watercraft as defined in claim 5 further comprising an inflatable deck in fluid communication with at least one said chamber.
7. An inflatable watercraft as defined in claim 6 wherein each one of said chambers is in fluid communication with at least one adjacent said chamber.
8. An inflatable watercraft as defined in claim 5 wherein said check valve is located in a bulkhead.
9. An inflatable watercraft as defined in claim 1 wherein said check valve is located in a bulkhead.
10. An inflatable watercraft comprising an inflatable tube and a single inflation valve, said inflatable tube having at least two chambers, each one of said chambers being in fluid communication with at least one other of said chamber through a check valve, whereby said at least two chambers are inflated through said single inflation valve and wherein said check valves are located inside said inflatable tube.
11. An inflatable watercraft as defined in claim 10 further comprising a deck check valve between said deck and one said chamber.
12. An inflatable watercraft as defined in claim 11 wherein each one of said chambers and said deck has a deflation valve.
