Container for pneumatic inflatable life raft, and pneumatic inflatable life raft equipped with same
View Patent ↗A rigid container having a generally horizontal elongated and non-parallelepiped shape, for containing a pneumatic inflatable life raft in deflated and folded state, is detailed. The container may be formed by two respectively upper and lower mutually assembled half-shells. The lower half-shell has, on its outer convex face, a zone with generally planar axial surface whereby the container can rest in stable position on a subjacent substantially planar support surface.
1. A rigid life-raft container of horizontally elongate and non-parallelepipedal overall shape, defining means for housing an inflatable life raft in the deflated and folded state, said container being formed as two half-shells, these being a lower one and an upper one respectively, assembled together, wherein each of the upper and lower half-shells exhibits, on an external face, a generally flat axially-extending region, whereby two containers can be stacked one upon the other, the lower half-shell of the upper container resting, via its generally flat region, on the generally flat region of the upper half-shell of the underlying container.
2. The life-raft container according to claim 1 , wherein the respective generally flat regions of the lower and upper half-shells exhibit reliefs of complementing shapes.
3. The life-raft container according to claim 1 , wherein the respective generally flat regions of the lower and upper half-shells exhibit reliefs of complementing shapes, wherein said generally flat region of the upper half-shell exhibits at least one projecting boss, and wherein the generally flat region of the lower half-shell exhibits at least one hollow impression of a shape that complements said boss.
4. A rigid life-raft container of horizontally elongate and approximately prismatic overall shape, defining means for housing an inflatable life raft in the deflated and folded state, said container being formed as two half-shells, these being a lower one and an upper one respectively, assembled together, wherein at least the lower half-shell exhibits, on an external face, a generally flat axially-extending region (i) comprising one face of the prismatic shape and (ii) by means of which the container can rest stably on a roughly flat underlying support surface.
5. A rigid life-raft container of horizontally elongate and approximately truncated cylindrical overall shape, defining means for housing an inflatable life raft in the deflated and folded state, said container being formed as two half-shells, these being a lower one and an upper one respectively, assembled together, wherein at least the lower half-shell exhibits, on an external face, a generally flat axially-extending region (i) comprising an axially extending flat intersecting the cylindrical shape and (ii) by means of which the container can rest stably on a roughly flat underlying support surface.
6. The life-raft container according to claim 4 , wherein each half-shell equipped with a generally flat region further comprises at least one radial protrusion which extends axially on each side of said axially-extending generally flat region and which has a generally flat front face substantially coplanar with said generally flat region, whereby the bearing surface of the container is increased and its stability is improved, especially when stacked.
7. The life-raft container according to claim 6 , wherein said protrusion is attached and fixed to the half-shell.
8. The life-raft container according to claim 6 , wherein said protrusion is molded as an integral part of the half-shell.
9. The life-raft container according to claim 6 , wherein each protrusion is in the overall form of a thick plate extending approximately transversely to the axis of the container and wherein each half-shell is provided with at least two protrusions axially distant from one another.
10. The life-raft container according to claim 6 , wherein the front face of each protrusion in the form of a thick plate exhibits at least two bosses or, respectively, two impressions which are transversely distant from one another.
11. The life-raft container according to claim 5 , wherein each half-shell equipped with a generally flat region further comprises at least one radial protrusion which extends axially on each side of said axially-extending generally flat region and which has a generally flat front face substantially coplanar with said generally flat region, whereby the bearing surface of the container is increased and its stability is improved, especially when stacked.
12. The life-raft container according to claim 11 , wherein said protrusion is attached and fixed to the half-shell.
13. The life-raft container according to claim 11 , wherein said protrusion is molded as an integral part of the half-shell.
14. The life-raft container according to claim 11 , wherein each protrusion is in the overall form of a thick plate extending approximately transversely to the axis of the container and wherein each half-shell is provided with at least two protrusions axially distant from one another.
15. The life-raft container according to claim 11 , wherein the front face of each protrusion in the form of a thick plate exhibits at least two bosses or, respectively, two impressions which are transversely distant from one another.
16. The life-raft container according to claim 1 , wherein this container is of axisymmetric cylindrical overall shape, and wherein at least the lower half-shell comprises at least one radial protrusion which extends axially and which exhibits a generally flat front face which, at least, is tangential to the external face of the half-shell or lies away beyond it, said front face of the protrusion constituting said generally flat region.
17. The life-raft container according to claim 16 , wherein said protrusion is attached and fixed to the half-shell.
18. The life-raft container according to claim 16 , wherein said protrusion is molded as an integral part of the half-shell.
19. The life-raft container according to claim 16 , wherein each protrusion is in the overall form of a thick plate extending approximately transversely to the axis of the container and wherein each half-shell is provided with at least two protrusions axially distant from one another.
20. The life-raft container according to claim 16 , wherein the front face of each protrusion in the form of a thick plate exhibits at least two bosses or, respectively, two impressions which are transversely distant from one another.
21. The life-raft container according to claim 1 , wherein (i) the generally flat region has hollow impressions and (ii) the lower half-shell is equipped with movement means arranged in conjunction with said generally flat region, in the hollow impressions of said generally flat region.
22. The life-raft container according to claim 1 , and of approximately cylindrical, or approximately prismatic shape, further comprising the life raft contained therein in a deflated and folded state.
23. The life-raft container according to claim 22 , in which the life raft contained therein is a high-capacity raft able to carry at least several tens of individuals.
