Abstract
Description
- The present invention relates to an Inflatable liferaft comprising at least an Inflatable first flotation tube, an inflatable second flotation tube; said first and second flotation tubes being adapted to be arranged substantially above each other, said first and second flotation tubes extending circumferentially for providing a substantially ring-shaped area; and a bottom element which is adapted to provide a bottom to the substantially ring-shaped area, which is detachably connected to the first and second flotation tubes.
- The term "ring-shaped area" is in this context to be construed as the tubes defining the outer periphery of the liferaft, i.e. the hull sides. The ring-shaped area is the area wherein the evacuated people are located while they are present in the liferaft. The configuration of the ring-shaped area may be round, elliptic, rectangular, pentagonal, hexagonal, octagonal, or the others as long as the flotation layers completely surround the ring-shaped area.
- When the known inflatable liferafts are being manufactured, the different parts of the liferaft are cut out of different pieces. Afterwards, they are assembled by welding or gluing into the elements, for instance tubes, hereinafter all the elements are being assembled into the liferaft by welding and/or gluing the separate elements together. Especially this last process is very time-consuming, as the connection or assembly is very difficult to perform. One of the most time-consuming processes in the assembly of the liferaft has been found to be the connection of the over and under flotation tubes. This is caused by the configuration of the tubes, which most often are round, and by the fact that that it is difficult to weld or glue two round tubes and their curved outer surfaces to each other. Furthermore, the working positions used by the persons connecting the tubes together are very demanding and ergonomically incorrect. There is thus a need for providing an inflatable liferaft which facilitates the manufacturing as well as the assembly processes.
- Furthermore, the range of inflatable liferafts, due to the many sizes in view of the capacity of the liferafts, which the manufacturer and supplier have to have in their product programme; is very high. Thus, the manufacturers and suppliers have to have many processes for manufacturing and assembling the different sizes of liferafts, which makes the manufacturing time-consuming and expensive.
- In
US 4,828,520 an inflatable liferaft is described, wherein the canopy, canopy support, floor pads, boarding ramp and at least one ballast are detachably attached to the hull of the liferaft and floor assembly. The hull of the liferaft consists of a plurality of generally vertically stacked inflatable tubular members and the floor is attached to the lowermost tubular member for preventing entry of water into the liferaft. However, the vertically stacked tubular members and the floor are mutually securely connected by means of known vulcanization or cementation techniques, thus, the liferaft is exhibiting the same disadvantages as explained above. - Another inflatable raft is known by
EP 0 849 163 . - An object of the present invention is to wholly or partly overcome the above disadvantages and drawbacks of the prior art. More specifically, it is an object to provide an inflatable liferaft which is easy to manufacture and assemble.
- Another object of the present invention is to provide an inflatable liferaft which is built-up of modules.

Fig. 10 , thesecond flotation tube 3 is shown displaced in relation to thefirst flotation tube 2. The matter is that thesecond flotation tube 3 is providing a larger ring-shaped area than thefirst floatation tube 2 so that a substantially funnel shaped configuration, seen in a cross-sectional view, of the inflatable liferaft is provided. In this embodiment, thefirst flotation tube 2 may, for instance, be used as a seat for the evacuated persons, and thesecond flotation tube 3 as a back rest. Obviously, thefirst flotation tube 2 may provide a larger ring-shaped area than thesecond flotation tube 3, so that an inverted funnel shape is provided, as shown inFig. 11 . The configuration shown inFig. 11 provides additional floor space to the liferaft. - In all the show embodiments, in
Figs. 4-11 , the first andsecond flotation tubes bottom element 5. However, additional connection reinforcement means (not shown) may be used and incorporated for strengthening the connection between the flotation tubes. The connection reinforcement means may for instance be placed on the opposite side of the flotation tubes in relation to the bottom element, and may extend vertically, horizontally, inclinedly or a combination thereof between the flotation tubes. Furthermore, the flotation tubes may also be connected by other means (not shown), such as accessories to the inflatable liferaft, for instance straps, ladders, slides, ramps, mooring systems, towing systems, ballast systems, canopy attachment systems or the like. Still, the connection of the flotation tubes via the bottom element is the primary connection. - Furthermore, a third flotation tube 9 may be arranged above the
