Description

The Invention relates to a universal for storage and transport as well other stationary or mobile use deployable folding container whose outer walls are movably connected to each other and in the folded Condition a small and in the unfolded state, a large volume having.

in the Related to advancing globalization and networking of economic processes as well as further expected crisis situations is also in the future with a growing need for economic transport solutions and flexible storage and transport systems.

in the The state of the art is for Transport and storage systems the already existing and proven technology with rigid and in their volume unchangeable containers known. However, this robust and inexpensive container technology is in specific use cases uneconomical, not adaptable and thus disadvantageous. conventional rigid containers functionally have a large volume and therefore also a big one Space required for empty transport and during storage of the container itself on.

Alternatively, collapsible containers are known, however, both the assembly and disassembly of collapsible containers already in use are associated with a great deal of time and assembly work. The assembly of larger containers is often difficult to handle. For example, containers with room contents of about 35 m ³ only with technical aids, such as cranes or other lifting equipment to build and thus their potential applications, eg. B. in terms of rough terrain, limited. In addition, additional equipment, such as cranes or lifting equipment, also incur additional costs.

The Although demountable containers offer space savings during transport and Storage in the empty state, however, are the unconnected and not in their size tuned items cumbersome to transport and can while lost transport.

The listed Disadvantages are partially resolved by known folding containers.

In the DE 298 00 032 U1 For example, a folding container is disclosed having a floor panel, a ceiling panel and side wall portions respectively connected to the floor panel and the ceiling panel, and optionally a front wall portion and a rear wall portion. This folding container is especially designed for the transport and storage of clothing.

A universal container intended for different uses, consisting of the basic modules base plate, ceiling plate and front and rear end wall, is in the DE 198 60 662 A1 disclosed. This container is mounted and dismantled by lateral flaps of the side walls. However, the side walls are not folded.

A hinged container consisting of roof part, bottom part, longitudinal walls, front and rear walls, whose longitudinal walls have a rigid frame and are rotatably mounted on the roof part and the bottom part, goes out of the DE 198 56 240 A1 out. During disassembly, the end wall and the rear wall are folded laterally in front of a side wall before the side walls are lowered in parallel.

The listed Faltcontainern is inherent that either the front or the rear wall in the disassembled state as individual parts present and transported Need to become or the side walls in are not foldable and thereby additional technical requirements it is necessary to set up or dismantle the container.

In the DE 299 14 390 U1 a collapsible container with top and bottom, two side and two end walls is disclosed, wherein the individual parts are connected to each other and from a position of use, starting in the container are formed foldable. The end walls fix in the unfolded position of use of the container, the side walls, so that the container reaches its static stability after unfolding the end walls and the static stability is ensured only by the walls.

From the EP 1 277 673 B1 shows a collapsible transport container, comprising a bottom part, a cover part, two side parts and two end parts and four each positioned in the corners, the ceiling part with the bottom part non-positively connecting, unchangeable in length and with the bottom part rotatably connected post elements. The transport container gets its static stability adversely only by the post elements, which must be dimensioned for the absorption of large forces and thus have a considerable, disadvantageous for the assembly, high weight.

As for the folding in the DE 299 14 390 U1 or the EP 1 277 673 B1 container described an additional hoist with the disadvantages listed is necessary, the above-mentioned related disadvantages persist.

In the US 3,612,330 A is described a lifting mechanism for a foldable container, each comprising two side and end walls. The side walls, consisting of upper and lower side wall part, are foldably connected to a roof and a floor element. The end walls each have a frame, which are formed from two at the lower end rotatably connected to the bottom element corner supports and a transverse strut. The container gets in the unfolded state its static stability only by the corner supports. The side walls do not fulfill any function in terms of statics. The lifting mechanism is adversely very complicated by a variety of moving parts and also very maintenance-intensive. Its drive by means of a crank is made difficult by the arrangement near the bottom, a uniform circumferential crank movement is impossible.

From the GB 1 159 908 A A collapsible container with front and back wall, floor and ceiling as well as a lifting device stand out. The lifting instrument offers the possibility to build the container by a single person, but is disadvantageous not connected to the container and therefore firmly anchored to the ground. The use of the container is thus heavily dependent on the condition of the terrain.
