Description

The invention relates to a universally applicable for storage and transport and other stationary or mobile purposes folding container in a double-decker design, the outer walls are movably connected to each other and in the folded state has a low and in the unfolded state, a large volume.

In the context of progressive globalization and the networking of economic processes as well as further expected crisis situations, a growing need for economic transport solutions and flexible storage and transport systems can be expected in the future as well.

In the prior art for transport and storage systems, the existing and proven technology with rigid and unchangeable in volume containers is known. However, this robust and inexpensive container technology is uneconomical in specific applications, not adaptable and thus disadvantageous. Conventional rigid containers have functionally a large volume and thus also a lot of space for empty transport and storage of the container itself.

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 with only technical aids, such as cranes or other lifting devices to build, and thus their use, for example, in terms of rough terrain, limited. In addition, additional equipment, such as cranes or lifting equipment, also incur additional costs.

Although the collapsible containers offer space savings during transport and storage in the empty state, but the unconnected and not matched in their size items are cumbersome to transport and can be lost during transport.

The listed disadvantages are partially remedied by known folding containers.

In the DE 299 14 390 U1 discloses a collapsible container with top and bottom, two side and two end walls, each consisting of an upper and a lower portion, wherein the upper portions are each connected by hinges to the ceiling and the lower portions to the ground. The sections of the side walls and the end walls are formed from a position of use starting in the container folded into it. The end walls fix in the unfolded position of use of the container, the side walls so that they can not fold back into the transport position, 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, which comprises 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 post elements. The in their outer dimensions, in particular in length, unchangeable post elements are rotatably connected to the bottom part and pivotable about an aligned parallel to the bottom part axis. At the articulation areas on the cover part, the post elements are slidably designed to be slidably receivable in guides. 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 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 corner supports and a transverse strut. The corner supports are rotatably connected to the bottom element at the lower end. The container gets in the unfolded state its static stability only by the corner supports. The side walls fulfill no function in terms of statics.

The lifting mechanism is integrated within the frame structure of the floor element and has four winches, which are driven by a common drive shaft connected. By means of rollers and ropes, the driving forces for erecting the container are transmitted in its corners. By a variety of moving parts of the lifting mechanism is thus disadvantageous very complicated and also very maintenance-intensive. In addition, the approach of driving the lifting mechanism as a coupling point of a crank for rotating the drive shaft laterally on the bottom element, so arranged near the ground, that a uniform circumferential crank movement is impossible.

All listed, known in the art containers are also designed only one-story and are not stackable in the unfolded state.

In the DE 10 2008 000 493 B4 discloses a single-storey folding container with two arranged between a roof element and a bottom element foldable side walls and each having a hinged front and rear walls. The side walls consist of an upper and a lower, along a longitudinal axis rotatably connected to each other by hinges side wall part. The front and rear walls are each arranged on one end side and the upper side wall portions each on a longitudinal side of the roof element and the lower side wall portions each on a longitudinal side of the bottom member rotatably by means of hinges and connected to each other. In the unfolded state of the folding container four height-adjustable corner supports are arranged vertically between the roof element and the bottom element. The folding container can be stacked when folded or unfolded.

From the DE 20 2004 000 168 U1 A foldable container emerges as a one- or two-storey construction, in which the folding functions are realized as rotating movements via incorporated rotary elements. The rotary elements have between the starting position and the end position movement angle of 90 ° to 180 °.

Object of the present invention is to provide a double-decker folding container available that is easy to assemble and disassemble without complex tools and to save space in the folded or disassembled state and thus inexpensive to transport and store. It should be applicable for various uses and have the required protection properties.

The object is achieved by a double-decker folding container according to claim 1. According to the concept of the invention, the double-decker folding container is designed as a statically coherent unit that is closed when folded and unfolded. Furthermore, only a small number of additional items are provided, which are also advantageous in the disassembled or folded state within the container and thus can not be lost during transport.

The double-decker folding container according to the invention has four foldable side walls, which are arranged between a roof element and an intermediate element and the intermediate element and a bottom element, as well as two foldable front and rear walls. Both the upper and the lower floor are each associated with two side walls and a front and a rear wall. The roof element is the upper floor and the floor element associated with the lower floor. The intermediate element is a connecting element between the two floors as a roof element from the lower floor and as a floor element from the upper floor. The side walls each consist of an upper and a lower side wall part rotatably connected to each other along a longitudinal axis. The front and rear walls of the upper floor are connected in each case with an end face and the upper side wall portions each with a longitudinal side of the roof element by means of hinges rotatably. The lower side wall portions are also mounted on a longitudinal side of the intermediate member also rotatably by means of hinges. The front and rear walls of the lower floor are each mounted with a front side and the upper side wall portions each with a longitudinal side of the intermediate member by means of hinges rotatably. The lower side wall portions are also connected to a longitudinal side of the bottom element also rotatably by means of hinges.

The invention includes as auxiliary structures a temporary for folding and folding the double-decker container on the intermediate element or on the bottom element to be fastened frame member and a for folding and unfolding the front and rear walls on the roof element or on the intermediate element to be fastened support element. In addition to the auxiliary structures include eyelets or tabs, ropes, pulleys and winches.

In the unfolded state of the double-decker folding container according to the invention four corner posts are arranged vertically between the roof element and the intermediate element and the intermediate element and the bottom element.

The four vertical corner columns of the upper floor are locked after unfolding by means of bolts on the roof element and the four corner columns of the lower floor of the intermediate element. The corner posts are additionally bolted to the roof element and the intermediate element or the intermediate element and the bottom element. By means of height adjustable via punch and screw corner supports, the side walls can be tightened by extending the punch and with the additional use of locking screws. The locking screws are doing through arranged on the corner supports eyelets passed so that the side walls are formed braced against the corner posts.

The outer boundary surfaces of the double-decker folding container according to the invention, which are formed by the foldable side walls of the side wall parts, the front walls, the rear walls, the roof element and the bottom element, and the intermediate element each consist of frames and infills.

The frame and the corner supports are preferably formed from hollow profiles. The circumferential hollow profiles of the frame of the roof element and the bottom element have an existing three rectangular chambers L-shaped plan, in which a chamber on its narrow side for better sealing has an offset. The circumferential hollow profile of the frame of the intermediate element also has a plan consisting of three rectangular chambers. In this case, two chambers adjoin each other with a narrow side on opposite sides of the third chamber, so that a flat surface is formed on one side of the profile. The respectively facing away from the third chamber narrow side of the first and second chamber also has an offset. The circumferential hollow profiles of the frame of the side wall parts, the front walls and the rear walls have an L-shaped plan, except for the profiles which abut the intermediate element or to the bottom element from above. These hollow profiles have a rectangular cross-section.

The frames and the corner supports are made of aluminum. Aluminum combines the advantages of a low weight with a relatively good strength and a reasonable price. Alternatively, steel or, under special circumstances, also plastic constructions can be used, provided that the required static characteristics are achieved by these materials.

In addition, the frames can be filled with insulation material between the panels and the hollow sections of the frame and the corner posts are at least partially ausschäumbar with plastics to improve the thermal insulation.

The frames of the outer walls also have claddings of aluminum sheets. Alternatively, plastics are used for the cladding. The panels are inexpensively attached to the frame with riveted joints. In addition, under the outer edges of the cladding adhesive joints are provided.

According to a preferred embodiment of the invention, the adjacent walls, such as the side walls, the front walls, the rear walls, the roof element, the intermediate element and the bottom element, provided with sealing elements, both in the folded and in the unfolded state of the container, the ingress of water in this or in the spaces between the individual elements prevent. The sealing elements, such as rubber, existing sealing elements have different shapes. The sealing elements between the corner supports and the roof, the intermediate or the bottom element are flat gaskets. The sealing elements for sealing the side wall parts with each other, the side walls and the front and rear walls each with the roof, intermediate or bottom element and the corner supports in the unfolded state and the brook, intermediate and bottom element in the folded state of the double-decker folding container have cavities to ensure optimum sealing.

The front walls and the rear walls are in the unfolded state perpendicular to the roof element, the intermediate element and the floor element and in the folded state of the double-decker Faltcontainers horizontally disposed within the roof element or the intermediate element that a layered arrangement arises. Considering that the side walls in each case in three planes, that is, both the roof and the intermediate element and the intermediate element and the bottom element, can fold and the side walls each consist of an upper and a lower along a longitudinal axis rotatably interconnected side wall part , is created in the folded state of the double-decker folding container a seven-layer arrangement, which is constructed as follows: floor element, lower and upper side wall portion of the lower floor and intermediate element with integrated rear and front wall, lower and upper side wall portion of the upper floor and roof element with integrated Back and front wall. The double-decker folding container is thus designed such that the side wall parts and the front and rear walls are folding inward foldable way.

The front walls and the rear walls are preferably designed to be lockable in the folded state on the intermediate element or on the roof element and in the unfolded state on the intermediate element or on the bottom element.

According to an advantageous embodiment of the invention, the ceiling of the lower floor and the floor of the upper floor are as a formed common intermediate element, so that the double-decker folding container represents a statically coherent and closed in the assembled and unfolded state unit. Compared to the possible execution stacked simple single-storey container, eliminating the additional fastening of the container with each other. The anchoring of the overall construction is thereby made much easier.

Furthermore, it is advantageous that the invention includes a pedestal, which can be arranged on the narrow side of the intermediate element. The pedestal is provided in the door area of the upper floor and serves to enter this area of the container. The pedestal can be mounted on the intermediate element via a detachable screw connection.

An embodiment of the invention is that a staircase leads to the upper floor and thereby allows easy walking on this floor. The staircase can be mounted with the arranged on the intermediate element pedestal via a detachable screw. The stairs are foldable particularly advantageous.
