Abstract

A collapsible cargo container, particular of rectangular or square cross section, has a bottom element, a top element, and side wall elements, which in the erected state for use are joined together by releasable plug-in connectors located in corner pillars at corner regions of the bottom and top elements. In the collapsed state for being shipped empty, the top element is joined to the bottom element with the same plug-in connectors, and the side wall. At least one door fits flush against adjacent side wall elements inwardly of the pillars, to permit flat folding of the container for shipment when empty.

Description

The invention relates to a collapsible freight container or container of rectangular or square cross-sectional shape with a base element, with side wall elements and with a cover element, which are rigidly connected to one another in an erected state and with at least one locking part which can be opened and closed, whereby in the corner areas of the base and the cover element releasable plug connection devices are provided for connecting the bottom and the cover element to the side wall elements.

In recent times, the problem of waste disposal has become increasingly important, and it is also a question of saving packaging materials, such as cardboard boxes, foils, paper bags, etc., which are generally used only once. Cardboard boxes, which would in principle be reusable, are consistently disposed of due to the relatively high return costs and the risk of possible damage after a single use. The disposal costs for industrial and commercial waste show a rapidly increasing trend.

There is therefore a need for a practical, reusable packaging that is sufficiently stable and wear-resistant on the one hand and on the other hand can be used so universally that it can replace the cardboard boxes in use today for many purposes. This applies e.g. typically for the textile industry, in which yarn packages have so far been supplied in large quantities by the yarn manufacturers to the yarn processing companies in boxes which are intended for single use only and whose return transport for reuse is considered not to be worthwhile because of the considerable space requirement.

Constructions for collapsible or collapsible containers have become known in particular from large container construction, which can be transferred from an upright use position into a flat empty transport position, in which the space requirement for empty or return transport is significantly reduced.

These large containers, the dimensions and basic components of which are standardized, are usually made of sheet steel. They are set up to be moved by means of special hoists, their special Training also depends on the goods to be transported.

In such a large container or container known from DE-OS 33 17 221, the end and side walls are rotatably connected to a flat, pallet-shaped base element by means of hinges, so that they can be opened onto the base element after the cover element has been removed, so that the container can be opened to transfer the flat empty transport position. The cover element is placed on the wall parts folded flat and firmly connected to them by means of bolts and tabs. Because of the relatively large weight of the wall parts and the cover element, the wall parts can only be folded in with the aid of lifting equipment, the correct placement of the cover element in such a way that the bolts used for fastening find their holes in a considerable degree of attention and skill on the part of the operating personnel. In addition, the hinge axes of the individual wall parts must be at a different distance from the bottom surface of the floor element in order to enable these wall parts to be folded flat. In addition to the fact that this can result in constructional difficulties, a predetermined sequence must also be observed when folding in, which also requires trained personnel to prevent damage to the hinges or the wall parts.

Basically, the same also applies to a collapsible large container known from CA-PS 875 957, in which the opposite end walls are designed as hinged doors, which are used for folding into the empty transport position about their vertical Hinge axes can be folded flat on the outside of the respectively assigned side wall. In addition, special seals are provided in this large container between the side walls and the cover as well as the base element and the doors in order to ensure at least a splash-proof seal of the container interior.

In another collapsible freight container known from DE-OS 38 05 981 according to the ISO standards, each side wall is constructed from three sections connected by hinges, while the end walls are movably mounted on the container in such a way that they move from the normal closed position into one Retractable position can be moved under the ceiling of the container. To fold the container, the side wall sections are folded inwards like an accordion around their hinge axes, so that in the empty transport position the cover part, the end walls, the middle and lower sections of the side walls and the base element lie one above the other in layers. This folding of the container can only be done by means of a hoist that engages the corner frames of the cover part, considerable attention being necessary in view of the risk of an accident.

In addition, it is known from DE-GM 86 11 553, in a large container, in which the end and side walls are connected to the base element via hinges, also to form the cover element in two parts and to connect them to the side walls via hinges. Doors provided in the end walls are designed in such a way that when the container is folded outwards they can be folded too flat on one another. This large container uses a tubular frame with cladding panels, with the wall parts in the upright position Use position are locked together by lever locks. The many hinge axes of this large container affect stability when erected and make it difficult to seal the interior of the container properly. Apart from that, handling this large container when folding is difficult and cumbersome.

Finally, from DE-OS 30 24 707 a freight container or container for piece goods or the like. known in lightweight construction, from which the invention is based and in which the use of hinges as a connecting means between the bottom and the cover element and the side wall elements is dispensed with. The bottom and cover elements and the side wall elements each consist of aluminum profile frames and thin aluminum panels connected to them, which are optionally provided with beads or molded-in stiffening ribs. The base element and the cover element are connected to one another by vertical posts at which the stable side walls are fixed, the posts on the base element and on the cover element being releasably connected by means of cuboid corner pieces, which carry pins which are formed in cavities of the hollow profiles Protruding corner posts. Additional fastening screws hold these connector devices arranged at the corners of the base and the cover element together.

When assembling or disassembling this freight container, as is necessary for transferring it to the upright use position or to the flat empty transport position, there are a relatively large number of separate individual parts. Apart from the fact that the assembly and disassembly process itself is relatively time-consuming and are cumbersome, special precautions must also be taken to ensure that the loose parts are not lost during the empty transport.

In contrast, the object of the invention is to provide a freight or transport container which is as free as possible from the described disadvantages of the large containers, can be manufactured inexpensively with low weight, is characterized by a robust and easy-care structure and is suitable for packaging a wide variety of goods, whereby at the same time, a transfer to a collapsed empty transport state is possible in a simple manner.

To solve this problem, the above-mentioned cargo container is characterized according to the invention in that the plug connection devices are set up in a folded empty transport state for connecting the cover element to the base element with the side wall elements inserted therebetween, and in that empty transport state the at least one closure part is accommodated on one of the side wall elements on the broad side .

This freight container is characterized by relatively few individual parts, which allow easy assembly, especially since the individual elements are only put together. In the folded empty transport state, the side walls and any doors etc. are accommodated between the base and the cover element, and since the cover element is firmly connected to the base element via the plug connections, the whole thing forms a flat, stable "package" with little Space requirements can be transported. There are no loose items; the side wall elements can be stacked on the base element in any order. By dispensing with a hinge connection between the side walls and the base or cover element, it is also ensured that the bottom surface of the cargo container facing the container interior can be made completely flat, that is to say without the need to provide strip-like mounting elements for hinge axes etc. at the edges . With the cover element and side wall elements removed, the base element can even be used directly as a pallet if necessary. The base and cover elements can also be combined with wall elements of different heights in order to adapt the height of the freight container to packaging goods of different heights if necessary.

In a preferred embodiment, the new cargo container can be designed such that its side wall elements and / or the base element and / or the cover element are at least essentially made of plastic. Fiber-reinforced plastics are particularly suitable for this purpose, namely both thermoplastics and thermosets, which can be processed, for example, in conventional pressing processes. However, it is also conceivable to produce individual elements or all elements using the plastic injection molding process. The elements can have a single-layer or multi-layer structure, if appropriate also consist entirely or partially of polyurethane foam. However, it is also possible to combine elements which have been produced using different manufacturing processes, if this is expedient with regard to price or manufacturing advantages. The simple structure consist of polyurethane foam. The simple structure of the new freight container allows a particularly tool-specific, precisely fitting production without any significant post-processing; it ensures a stable construction, whereby generally no surface protection is required, since the plastic material can be colored in any color and, depending on the choice of material, is also largely impact and scratch resistant.

Of course, other materials can of course also be used to manufacture the new freight container if this appears appropriate with regard to the intended use. It is conceivable to manufacture the container or at least some of its elements from light metal or generally sheet metal or even from wood, as well as using composite materials. Because of its light weight, it can be easily assembled and disassembled without the use of lifting equipment. It is suitable for the packaging and transport of practically any goods, including food, glass and porcelain products, etc. Especially in the textile industry, such freight containers can be used to advantage for packaging in the transport of all kinds of yarn packages. The freight containers can also be used for storage purposes.

In the plastic version in particular, the freight containers can also be stored outdoors for long periods of time without problems, a splash-water or dust-tight seal of the container interior, which may be necessary with regard to the goods to be transported, being possible without great effort.

Advantageously, the side wall elements can have parallel post-like profiles on two opposite sides, on which parts of the plug-in connection devices may be arranged. These profiles can either be formed directly in the material of the side wall elements or molded onto them, as they can also be parts of a circumferential frame. On the other hand, the profiles can also be made of another material, for example metal, in particular light metal and molded into the side wall elements or connected to them in some other suitable way.

It is advantageous if the plug connection devices have plug pins arranged on one of the elements to be connected to one another and receptacles for these plug pins arranged on the other element. These spigots not only allow easy handling, but they can also be designed so easily that they ensure a perfect connection of the elements to one another even after prolonged use of the freight container.

The profiles mentioned can protrude on the respective side wall element over the wall surface, i.e. be sublime; they can be designed as open or closed hollow profiles or as round or otherwise suitable cross-sectional tubes.

As a closure part, the cargo container can have at least one door which is pivotally mounted on a side wall element or a part connected to it about a hinge axis and which, in the transport state, is designed to be folded flat against the side wall element. If, as mentioned, the profiles are arranged projecting over the wall surface, the door can protrude from the two Profiles limited recessed area of the respective side wall element can be recessed retractable, so that the wall element with the folded door - or with two doors folded - forms a substantially flat panel that is free from damage to any protruding parts in the empty transport state between the bottom element and the cover element is safely housed with a low height extension.

It is advantageous if hinge elements are connected to the profiles or the side wall elements, each of which has two parallel hinge axes, one of which allows the hinge element to be pivoted with respect to the side wall element and the other is assigned to the door. To increase the stability of the cargo container in the erected state of use, each hinge element can be designed to be lockable in at least one position. Embodiments are also conceivable in which the hinge element is detachably attached to the respective side wall element or to the profile thereof, such that e.g. the door can easily be removed if the freight container is to be used openly on one side or on both sides at the end faces for certain purposes.

Between the hinge element and the associated profile or side wall element, as well as between the at least one door and the hinge element and / or the profile and / or the base or cover element, sealing means can be arranged in each case, how it is also possible to provide sealant between the base and / or the cover part and the side wall elements if this appears necessary in view of a dust and / or splash-proof closure of the transport goods contained in the freight container.

In a modified embodiment, which is particularly suitable for the transport of bulk goods, the at least one closure element can also be designed as a slide which is displaceably guided in guide means of the side wall element and / or the base and / or the cover element or of parts connected to them . In the closed position, this slide can be locked by the base and / or the cover element, but it is also conceivable to provide separate locking means for this. The cover and / or the base element are generally designed to be closed, at least in the area of the base or cover surface. Depending on the intended use, one or both of these elements can also be designed in the form of a frame such that the top or bottom surface contains one or more small or larger openings.

Stop means for a closure part (door, slide, roller blind, blind, etc.) can be arranged on the base and / or the cover element. These stop means can have, for example, at least on the bottom element a preferably molded raised stop bar; but you can also by at least a stop shoulder should be formed. It has proven to be advantageous if, when the stop means are designed as stop strips, they are designed to be closed all the way round, in which case the closure element which has been folded up in the manner already mentioned can be fixable in this position by the stop means. The hinge element explained can also be fixed in its respective position by this stop bar. In addition, the arrangement and design of this stop bar can be selected so that the side wall elements inserted in the empty transport state between the base and the cover element together with the respective closure part are held laterally immovably between the base and the cover element.

In particular, in cases where a splash-proof closure of the interior of the container is important, it is finally advantageous if a space of the base element delimited by the lifting means has an outwardly leading drainage device which ensures that condensation water occurring on the inside of the container under extreme conditions of use , which runs downwards on the vertical inner wall surfaces, is collected in the edge space of the base element mentioned, from which it is discharged to the outside via the drainage device, without being able to act on the goods to be transported.

The at least one locking part, for example in the form of a door, can be the same height as the side wall elements. In certain cases it is but it is advantageous if the at least one closure part has a height different from the height of the side wall elements, wherein the base and / or the cover element in the region of the side wall elements or the closure part can be provided with projecting or recessed side wall parts, which are in the erected state of the freight container connect to the side wall elements or to the at least one closure part.

A particularly expedient embodiment of the new freight container is characterized in that the side wall elements are captively connected to the base and / or the cover element by connecting means which are designed to permit the transfer of the side wall elements from the erected to the collapsed position. In this way, it is automatically ensured that the side wall elements come to lie in the correct position in relation to the base and cover elements during the transfer into the folded empty transport position. For this purpose, the connecting means can have tab-like connecting elements which are arranged in the region of the end faces of the side wall elements and are pivotably mounted on the base or cover element and the respective side wall element and are longitudinally displaceable to a limited extent on at least one of these elements. These tab-like connecting means not only form guide means for the side wall elements when folded or raised, but they can also act as stiffening elements for the erected cargo container at the same time. If it seems desirable to avoid the protruding parts, the connecting means can be arranged recessed otherwise.

In another embodiment, the connecting means can also have at least one, preferably elastic, band-like element connected to the base or cover element, to which the respective side wall element is coupled.

It is often sufficient for the side wall elements to be bluntly connected to the base and cover elements. To increase the stability of the cargo container in the erected state and to improve the sealing conditions, it may be advisable to form or arrange interlocking interlocking links between the bottom and / or the cover element and the side wall elements, for example in the manner of a tongue and groove connection can be designed.

At least in the corner areas, the base element can have stand-up feet, which allow the freight container to be transported from all sides by means of a forklift or to set it up on a damp installation surface. These feet can be molded on or attached as separate parts. To save space in the warehouse or during transport, it is often desirable to be able to stack several such freight containers on top of each other. That is easily possible. In order to ensure a secure hold of the stacked containers, the cover element can have guide means for the feet at least in the corner areas have stacked second cargo container. The cover element and / or the base element and / or at least one of the side wall elements can also carry side bumpers to protect the freight container, in particular for applications in which somewhat more rough operation is to be expected.

Since the new cargo containers present themselves as bodies with a rectangular or square cross-sectional shape that are essentially limited in area, there are advantages for optimal use of the transport space if such a new cargo container has the following external dimensions when erected: Length: 120 cm Width: 115 cm Height: 118 cm.

These external dimensions allow two freight containers to be placed next to and one above the other in a standardized large container.

Further features of the new freight container result from the following description of an embodiment of the object of the invention, which is shown in the drawing.

The cargo container or small container shown in FIGS. 1 to 7 has an essentially cube-shaped or parallelepiped-like shape with planar outer surfaces standing at right angles to one another. In order to facilitate understanding, it is only illustrated in its basic structure in various states in these figures; individual structural details will then be explained with reference to the following figures.

The freight container has a substantially rectangular, flat, plate-shaped base element 1, which is provided in the corners with four angular feet 2, between each of which a space 3 is left, which allows, for example, to lift the freight container with a forklift. Two substantially parallel side wall elements 5 are placed on the flat bottom surface 4 (FIG. 2) of the base element 1 facing away from the support feet 2, which in turn carry a cover element 6 which is flush with the side wall elements 5 on the edge side.
The cover element 6 is formed with a flat outer cover surface 7 and carries in the four corners over the cover surface 7 protruding angle strips 8, which act on the one hand as corner reinforcements for the cover element 6 and on the other hand serve as guide means for the feet 2 of a stacked freight container of the same type, such as this can be seen from Fig. 2. For this purpose, the distance between mutually opposite inner surfaces of the angle strips 8, taking into account the required play, is likewise the distance between the associated, mutually opposite outer surfaces 9 angular feet 2 selected, such that the stacked freight container is properly guided laterally when stacked freight containers.

On its front and rear end, the cargo container can be closed by locking parts in the form of two doors or door halves 10, which, pivotable about vertical hinge axes, are each attached to elongated, strip-like hinge elements 11, which in turn are not shown in FIGS. 1 to 7 Hinges further shown are connected to the side wall elements 5. The hinges serving for the pivotable mounting of the doors 10 on the hinge elements 11 are designated by 12.

As shown in FIG. 2 in particular, the doors 10 can be opened or closed at any time, even when the freight containers are stacked, so that they can be loaded or unloaded without hindrance, which can be particularly advantageous if the freight containers are used as storage or Storage containers are used. The opening angle of each door or door half 10 is approximately 90 to 100 °; Depending on the design of the hinge straps forming the hinges 12, which can optionally also have two hinge axes, an opening angle of 180 ° and more can be achieved if this should be necessary in individual cases.

The cargo container shown in Fig. 1,2 in the erected state of use can be folded. In order to enable this collapsibility, are to connect the wall elements 5 with the floor and the cover element 1 and 6 in the corner areas of these two elements provided connector devices, the structure of which can be found in particular from FIGS. 3 and 6:

The cover element 6 has, on the opposite side walls assigned to the side wall elements 5, protruding, molded, strip-like side parts 14, in the extension of which four parallel pins 15 of rectangular cross section are arranged in the four corners of the cover part 6. The pins 15 projecting from the cross-section of the substantially U-shaped cover part 6 are also assigned in cross-section rectangular receptacles 16 which are formed by the inner profile of four profiles 17 which are essentially rectangular or square in cross-section and which act as posts and on opposite end faces delimit a side wall element 5 in pairs. The profiles 17 act as posts; they absorb loads which can act on the freight container from above in the vertical direction, for example when stacking. In addition, they bring about reinforcement and stabilization of the flat and thinner side wall panels 18 lying between the profiles 17.

In a modified embodiment, the profiles 17 can also be designed in the form of cylindrical tubes or profile tubes of another cross-sectional shape, as is also possible to use open profiles. For example, they can be embedded in the form of metal profiles in the side wall elements 5, which are made of plastic, but the arrangement can also be such that they are made directly from the material of the side wall elements 5 are worked out. It should be mentioned that in principle, embodiments are also conceivable in which the profiles 17 do not extend over the entire height of the side wall elements 5, but are replaced by strip-like parts of shorter longitudinal extension adjoining in the region of the upper and lower edges of the side wall elements 5.

On the side opposite the receptacles 16, each wall element 5 is provided with two pins 19 which are also rectangular in cross section, which are aligned coaxially with the receptacles 16 and are essentially identical to the pins 15 of the cover part 6. In the exemplary embodiment described, the pins 19 are inserted into the cavity of the profiles 17 and fixed therein. As can be seen in particular from FIG. 6, in the bottom element 1 in the region of its corners 4 rectangular pin holes 20 are formed in cross section, which serve to receive the lower pins 19 of the side wall elements 5 and are designed accordingly to these pins 19.

For example, Fig. 3.5 show that the front side arranged on the side wall elements 5 profiles 17 are arranged to protrude inward beyond the otherwise smooth inner wall surface 21 of the wall elements 5, such that they each have a channel-like between them together with the inner wall surface 21 limit recessed space and give the entire wall element 5 an approximately U-shaped cross-sectional shape in cross section. The outer wall of the wall elements 5 is smooth; but it can also be profiled or otherwise designed. This also applies to the inner surface of the wall elements 5 and the base and cover elements 1 and 6.

In this context, it should be mentioned that, of course, embodiments are also conceivable in which the profiles 17 are arranged to project at least over part of their height toward the outer wall of the wall elements 5, or form parts of a stable closed frame, are inserted or molded into the wall panels .

The hinge strips 11, on which the doors 10 are hinged outwards in the manner already described, about a first vertical hinge axis, are in turn mounted on the profiles 17 about a second vertical hinge axis, so that the doors 10 together with the hinges Hinge strips 11 in the manner shown in FIG. 5 can be folded into the space of the associated side wall element 5 delimited by the two profiles and the inner surface 21. The extent to which the profiles 17 protrude beyond the inner surface 21 corresponds essentially to the thickness of the doors 10, so that in the folded state of the doors 10 shown in FIG. 5 on the left-hand side, a substantially continuously flat inside of the in this state results in essentially tabular side wall element 5. This is also evident from FIG. 4, where both side wall elements 5 are illustrated with the doors 10 retracted and retracted.

The doors 10 (FIG. 3) have a greater height than the side wall elements 5. They stand on the flat bottom surface 4 of the bottom element 3 with a play required for mobility below; at its upper edge, in the erected state (FIG. 1), the cover element 6 adjoins with an end surface 22 (FIG. 3) which is recessed relative to its side walls 14. On the flat floor surface 4 of the base element 1 and optionally on the end face 22 of the cover element 6 are arranged inward projecting stop means for the doors 10, which in the present case are formed by an all-round stop strip 23 (FIG. 4), the exact design of which is also based on FIG 12, 13 will be explained.

The handling of this freight container described so far is as follows:
In the erected state of use, as illustrated, for example, in FIGS. 1, 2, the base and cover elements 1 and 6 are plugged together with the side wall elements 5 via the pins 15, 19. The peg connections in the corners of the base and cover elements 1 and 6 are secured by locking devices which, for example, have aligned bores 24 (FIG. 3) provided in the profiles 17 and the pegs 15, 19, into which indicated at 25, if necessary, locking pins held captively by a security chain can be inserted. The doors 10 can optionally be closed or opened, wherein locking devices indicated at 26 in FIG. 3 can be provided on the doors 10.

Depending on the particular application, the cargo container can also be used in the manner of a pallet after removal of the cover element 6 in the state shown in FIG. 4, in which the doors 10 are folded into the channel-like depressions of the side wall elements 5, a loading and Unloading is possible from both ends as well as from above. Of course the cover element 6 can also be placed on the freight container in the state shown in FIG. 4, or, for example, placed after the loading, in order to mention a further application variant. The folded doors 10 together with the profiles 17 and the bottom surface 4 form flat inner surface areas for the container used in this way, which, for example, facilitates the insertion of lumpy goods.

To fold the doors 10 into the position according to FIG. 4, in order to overcome the stop bar 23 of the base element 3, either the side wall elements 5 have to be lifted a little, or the doors 10 are mounted in their hinges 12 to a limited extent, as is shown in each will be explained later. Another possibility is that the hinge elements 11 are in turn arranged to be displaceable to a limited extent with respect to the side wall elements 5 along their hinge axis.

Basically, it should be noted at this point that, instead of the two-wing design of the doors 10 shown, a single-wing door construction would naturally also be possible, in which case the door or the like only on one of the side wall elements via a hinge element 11. is struck.

In any case, the cargo container can be loaded not only through the doors 10, but also when the cover part 6 has been removed, as shown in FIG. 3, if this should be advantageous in individual cases.

For the return transport, in particular, the empty freight container can be transferred into a flat, empty transport position in a few simple steps, which is shown in detail in FIG. 7. For this purpose, after loosening the locking pins 25, the cover element 6 is removed (FIG. 3), whereupon the side wall elements 5 are pulled off the base part 1 and the doors 10 are folded inwards (FIG. 5), so that they lie flat on the broad side Inside of the wall elements 5 are sunk.

The now essentially tabular wall elements 5 with the retracted recessed doors 10 are now simply laid flat on top of one another on the floor element 1 from the manner shown in FIG. 6, the order being irrelevant.

Now the cover element 6 is inserted with its pin 15 into the pin holes 20 of the base element 1, which results in the compact flat unit illustrated in FIG. 7, in which the cover element 6 is directly rigidly connected to the base element 1 and the side wall elements 5 with the folded doors 10 are captively held between the overlapping cover element 6, which is approximately U-shaped in cross section, and the flat base element 1.

In this flat, tabular state according to FIG. 7, the collapsed freight container has only about a fifth of the space required by the freight container shown in its upright use position in FIG. 1. The flat compact "package", as shown in Fig. 7, can also be easily transported upright; several such packages can also be stacked. Since, as already explained, the distance designated 27 in FIG. 7 is more parallel Outer surface of the feet 2 is slightly smaller than the assigned distance 28 opposite inner surfaces of the angle strips 8 of the cover element 6, a perfect lateral guidance of the stacked cargo containers is ensured even in the folded state, while at the same time the stacking process is facilitated.

The re-erection of the freight container from the collapsed state according to FIG. 7 is carried out in the reverse manner as described above. Since the cover element 6 and the bottom element 1 are connected to the wall elements 5 only by plug connections which are very stable and easy to handle, the conversion of the freight container from the use state into the empty transport state and vice versa requires only a few simple steps, which can be carried out even by inexperienced people further can be carried out.

In the following, some structural details of the cargo container described only with reference to FIGS. 1 to 7 are explained in terms of its basic structure and mode of operation:
As a rule, it is expedient to captively connect the base element 1 or the cover element 6 to the wall elements 5 in such a way that the freight container can be converted from the use state into the empty transport state and vice versa without loosening the corresponding connecting means. In a particularly simple and expedient embodiment, this can be done, for example, in the manner shown in FIGS. 8 to 10:
On the floor element 1 there are 10 on the front side next to the doors two flat tabs 29 rotatably supported by means of corresponding fastening screws 30. Each tab 29 has an elongated hole 31 into which a head screw 32 engages, which is fastened axially parallel to the fastening screw 30 on one or the other wall element 5 in the region of its profile 17.

From a comparison of Fig. 8,9 it can be seen that the length of the tabs 29 and their elongated holes 31 is selected so that, starting from the position of use according to Fig. 8, the respective side wall element 5 can be raised until its pin 19 are excavated from the pin holes 20 (Fig. 9). The side wall elements 5 can thus be folded flat on the base element 1 in any order, as shown in FIG. 10. The tabs 29 assume a corresponding inclined position. In addition to their already mentioned function of captively connecting the floor element 1 to the wall elements 5, the tabs 29 also fulfill a guiding task for the wall elements 5 when they are plugged onto the floor element 1. In addition, they form in the folded empty transport state shown in FIG. 10 the cargo container an additional lateral securing for the side wall elements 5 lying between the U-shaped cover element 6 and the base element 1.

In the region of the corners, bumper strips 33 projecting laterally on the base element 1 are provided, which may optionally also consist of an elastic material, for example rubber. These protrude into 9 can be seen laterally over the tabs 29 so that they protect them from the outside while at the same time protecting the outer surfaces of the wall elements 5 against scratching and damage.

In principle, however, it would also be possible to arrange the tabs 29 sunk on the base element 1 and on the wall parts 5 by forming these elements with corresponding recesses.

Alternatively, it would also be conceivable to arrange the tabs 29 not on the base element 1 but on the cover element 6 in a corresponding manner by means of the fastening screws 30, so that when the cargo container is folded, the wall elements 5 are inserted into the cover element with a U-shaped cross section and then the bottom element 1 is plugged onto its upwardly pointing pin 15.

Instead of the tabs 29, other suitable connecting means can also be used to captively connect the side wall elements 5 to the base or cover element 6. Such connecting means can also include safety chains or flexible straps, for example. Such an alternative solution is shown in FIG. 13: on the floor element 1, a flexible band 34 is fastened at one end at 35 for each wall element 5 and at the other end at 36 is connected to the respective wall element 5. The flexible band 34 also allows the pins 19 of the wall element 5 to be lifted out of the pin holes 20 of the base element 1 (FIG. 9) and then that Place the wall element on the floor element 1.

11 to 13 illustrate in particular the exact structural design of the strip-like hinge elements 11:

Each of the hinge elements 11 is made in the form of a profile rail, preferably made of aluminum or a fiber-reinforced plastic, and is rotatably supported by means of a hinge 34, the vertical hinge axis of which is indicated at 35 (FIG. 11) on the profile 17 designed in the form of a rectangular profile tube. The profile 17 is enclosed on two sides by the plastic material of the wall element 5, the hinge 34 being arranged in the corner region between the profile 17 and the inner wall surface 21. The door 10 is attached to the hinge element 11 by means of the hinges 12, the vertical hinge axis of which is designated by 36 and parallel to the hinge axis 35 and extends laterally at a small distance next to the profile 17. The hinge element 11 is also formed with an edge-open groove 37 into which an elastic sealing strip 38, optionally profiled as a lip seal, is interchangeably inserted, which cooperates with a corresponding sealing surface 39 on the door 10, such that when the door 10 is closed, the container interior is effectively sealed against splash water and dust in this area. In addition, the hinge element 11 lies in the use position shown in FIG. 11 with a stop surface 390 on the inward-facing side surface of the profile 17, with which it rests against one outward pivoting about the hinge axis 35 is fixed in position. If necessary, a sealing strip similar to 38 can be arranged in the area of the stop surface 390, which cooperates expediently with the profile 17 and also produces a seal in this area.

The material for these sealing strips (e.g. 38) is e.g. Foam rubber with a cork coating to prevent the doors 10 from freezing, especially if the freight container is to be stored outdoors. Other suitable sealing materials are naturally also possible.

The stop bar 23 arranged on the bottom surface 4 of the bottom element 1 is, as can be seen from FIGS. 11 to 13, formed all round closed with sections which extend essentially parallel to the side wall elements 5 and the closed doors 10. In the area of each hinge element 11, this stop bar 23 is set back inwards at 40 so far that, when the cargo container is in the erected state of use, it also acts as an internal stop for the sealing element 11. The sealing element 11 is thus locked in position in the position of use shown in FIGS. 11, 12 between the part 40 of the stop bar 23 and the inner surface of the profile 17, against which it rests via the stop surface 390.

The stop bar 23 also runs with its section 41 parallel to the respective wall element 5 at such a distance from its inner surface 21 that when the doors 10 are folded into the wall element 5 these are locked in position together with the hinge element 11. This is particularly important if the freight container with the lowered sunken doors 10 is to be used, for example, for loading or unloading, as has already been explained with reference to FIG. 4.

In order to ensure a splash-proof and dust-tight closure of the doors also in the area of the door gap, a sealing strip similar to the sealing strip 38 can be provided either on the door 10 or on the end strip 23 in the area interacting with the door 10. Each door can also carry an all-round closed frame seal on the inside with which it bears against corresponding sealing strips on the hinge element 11 and the stop strip 23 of the base element 1 and a correspondingly designed stop strip on the end face 22 of the cover element 6.

FIG. 11 shows the door 10 in the closed state, the profiled door leaf, optionally provided with reinforcing ribs, resting against the stop bar 23 at 42. As explained, the hinge element 11 is locked in position.

In Fig. 12 the door 10 is illustrated in the fully open position, the opening angle being approximately 90 to 100 °, which is normally sufficient. Of course, the opening angle can also be chosen larger if this should be necessary in individual cases. All that is required is to advance the hinge axis 36 further to the front of the freight container and / or that Profile 17 can be changed in its shape. The profile 17 and thus the side wall element 5 forms the door stop in this position at 43 at the same time.

Finally, in FIG. 13 the door 10 is shown with the hinge element 11 in the lowered position folded into the wall element 5, in which, as already mentioned, it is locked in position by the section 41 of the stop bar 23 when the freight container is erected.

The all-round stop bar 23 forms a self-contained drainage wall on the bottom surface 4, which prevents the penetration of condensation water, for example, which forms on the inner wall surfaces 21 and collects on the bottom surface, into the interior of the freight container. At the same time, it acts as an additional stiffening rib for the bottom element 1. In order to ensure unimpeded drainage of, for example, condensation water that collects on the bottom surface 4, the bottom element 1 is provided with a drainage device in the form of at least one drainage hole 44, which in the from the stop bar 23 and the side wall elements 5 limited space opens (Fig. 13).

The hinges 12, 34 can be designed as desired in the form of common hinge straps. However, it is expedient to select these hinges so that the doors 10 can be removed from the hinge elements 11, for example in the event of a repair, and / or the hinge elements 11 in turn can be released from the side wall elements 5 on the hinges 34 and thus removed from the freight container .

In the simple embodiment of the freight container shown more schematically with the aid of FIGS. 1 to 7, the wall elements 5 and the cover element 6 and the base element 1 are flat in the manner shown in FIG. 3, for example, on sides abutting one another in the erected state of use. This is sufficient for a variety of uses of the freight container. However, if, for example, better sealing conditions are involved in the area of these parting lines or gaining additional stability, a positive connection of the elements mentioned in the area of the parting lines is preferable. An example of this is illustrated in FIGS. 14, 15:

Between the side wall 14 of the cover element 6 and the wall panel 18 of the respective side wall element 5, a tongue and groove connection is provided in the region of the abutting surfaces, which consists of a groove 45 arranged in the side wall 14 and a spring 46 on the wall panel 18 which engages therein. A corresponding tongue and groove connection is also provided between the base element 1 and the wall panel 18 of the respective side wall element 5 (FIG. 15); the groove in the wall panel 18 is designated by 47, while the spring of the base element 1 engaging in this is illustrated at 48.

Sealing elements similar to the sealing strip 38 (FIG. 11) can of course also be inserted into the grooves 45, 47 if this should prove to be expedient in the individual case. In addition, labyrinth seals or the like can alternatively be provided instead of the tongue and groove connections mentioned.

In the described embodiments of the freight container, the cover element 6 is illustrated closed with a flat (FIG. 1) or a slightly curved upward or roof-shaped outer surface 7 (FIG. 10). For certain purposes, for example in the manner of a chest or a basket, it may, however, be expedient to make the cover element 6 open, as is illustrated in FIG. 16. Here, the cover element 6a is constructed in the form of an open frame, which encloses an access opening 50 and, apart from the missing outer surface 7, is similar to the construction of the cover element 6 described with reference to the previous embodiments. The same parts are therefore provided with the same reference numerals and are not explained again.

The cargo container provided with such a frame-like cover element 6a can also be provided with the doors 10 of the described embodiments, but - as in the other embodiments - a differently designed closure part can also be used. As an example of this, FIGS. 16 to 18 illustrate an embodiment of the freight container that is particularly suitable for receiving bulk goods, in which two closure elements in the form of two sliders 51 are provided. These slide 51 forming the front and rear wall are inserted into vertical slide grooves 52 (FIG. 17) of the parts of the side wall elements 5 forming profiles 17, in which they can be displaced upwards as far as desired. As can be seen from FIG. 18, a support edge 52 is formed on the base element 3 for each slide 51 followed by a vertical sealing surface 53 which supports the slide 51 inwards and at the same time forms a double surface seal together with the support edge 52. If necessary, sealing strips similar to the sealing strip 38 (FIG. 11) can also be arranged in this area in the base element 1, to which corresponding sealing strips may also be assigned in the region of the guide grooves 52, as indicated by dashed lines at 54 in FIG. 17.

Basically similar relationships can also exist in the area of the cover element 6 (FIG. 18) or the cover element 6a (FIG. 16). As can be seen from FIG. 18, the cover element 6 is formed in the region of its outer edges on the end faces in each case with a groove 55 which, when closed, engages over the slide 51 provided with a handle 56. The slider 51 is supported at 57 against a corresponding stop surface 58 of the cover element 6, which, if necessary, can also be formed with the sealing strip mentioned. As a rule, an additional sealing measure against splash water is not necessary with this version.

In the embodiment according to FIG. 18, the slide 51 is automatically secured in the closed state by the cover element 6, so that actuation is not possible without removing the cover element 6. This solution is therefore particularly suitable for freight containers intended for the transport of piece goods.

In contrast, a variant is shown in FIG. 16 in which the essentially tab-shaped slide 51 when the cover element 6a is placed on it can be pulled out as far as possible without hindrance, so that there is an adjustable gap 60 on its lower edge. When used for the transport of bulk goods, for which this embodiment is particularly intended, the bulk goods can be discharged through the gap 60 in this way, if necessary with the freight container being tilted accordingly.

In order to receive the slide 51 in the empty transport position, as can be seen from FIG. 17, an additional slide guide is formed on the profiles 17, which is formed by a further guide groove 61 running at right angles to the guide groove 52, into which the dash-dotted line at 62 indicated slide is inserted.

Any condensation water that may form on the inside of the slide 51 can be discharged to the outside via a collecting channel 63 (FIG. 18) molded into the base group, which may also be assigned an additional drainage device.

When using the all-round stop bar 23 (see, for example, Fig. 11), the dimensions of the side wall elements 5 are selected such that when the side wall elements 5 are placed on the base element, the stop bar 23 also serves as a lateral holder for the side wall element 5 lying thereon. The already described lifting of the side wall elements 5, which is required by the stop bar 23 projecting over the flat bottom surface 4 for folding the doors 10 into the lowered position according to FIG. 5, can, if necessary, be avoided without further ado.

For this purpose, for example, the hinges 12 and / or 34 (FIG. 11) can be designed in such a way that they allow a limited height mobility of the respective door 10 and / or the associated hinge element 11 relative to the base element 1, which allows the door 10 to the extent that it can be pivoted over the stop bar 23.

An embodiment operating in this sense is illustrated in FIG. 19:
The hinges 12, on which the door 10 is attached to the hinge element 11, each have a first hinge part 64 connected to the door 10, which is rotatably mounted on a hinge pin 65, which is pressed into the other hinge part 66, which is connected to the Hinge element 11 is connected. The door 10 can be displaced with the hinge parts 64 on the hinge pin 65 by an amount x which is determined by a stop, which is designed, for example, in the form of a small angle 66, which is fastened to the hinge element 11 above a hinge 12.

The dimension x corresponding to the maximum lifting movement of the door 10 is greater than the height of the stop bar 23.

The bottom elements 1, the cover element 6 and the wall elements 5 are each formed in one piece from plastic material in the described embodiments, including the doors 10. This plastic material can be fiber-reinforced; as described, the elements can be delimited with smooth walls or can also be formed with reinforcing ribs and parts, if appropriate, on the inside. Reinforcements in the form of frames, strips and the like can be embedded in the elements, it also being possible to use metal, preferably aluminum, for such supporting frame parts and reinforcements, in particular in the floor assembly. The design can be such that, together with the profiles 17, a force-absorbing frame construction results, in which the wall parts or panels in between each have only an essentially enveloping function.

This does not limit the choice of materials. In particular, metal constructions are also conceivable. Due to the simple structure, the elements 1,5,6 can also be covered on the inside or outside with a heat or cold insulating material, as is also possible in To provide special receiving devices, for example for yarn packages or the like, inside the freight container.

so daß diese besonders platzsparend in genormten Großcontainern untergebracht werden kann.The outer dimensions of the cargo container are preferred

$\text{Length x. Width x height = 120 x 115 x 118 cm,}$

so that it can be accommodated in a particularly space-saving manner in standardized large containers.

Finally, it should also be mentioned that the plug connections provided at the corners of the base and cover elements 3 and 6 can of course also be designed differently, for example in such a way that the base element 1 is provided with protruding pins 19 which fit into corresponding receptacles 20 in engage the profiles 17 or the side wall elements 5. If necessary, the floor element itself can also contain a trough-shaped floor surface 4, as is a general adaptation to the most varied of uses and to a variety of goods to be transported.

The cover element 6 and / or the base element 1 and the wall elements 5 can, if necessary, also be designed to be bulletproof, so that the cargo container can also be used for military purposes.
