Description

The invention relates to a transport container with a pallet base and a folding wall ring according to the preamble of claim 1.

Such a transport container is already out of the DE 10 2012 018 232 A1 known. The transport container comprises a pallet floor and a Faltwandungsring. The folding wall ring comprises an inner skin and an outer skin of a thermoformable plastic. The Faltwandungsring is made for example by means of the so-called twin-sheet process and rotates the pallet base. Further, the Faltwandungsring between a folded state and a folded state is foldable. In the folded state, the Faltwandungsring can be applied to the pallet floor. In the unfolded state, the Faltwandungsring forms a directed in the normal direction to the pallet floor wall.

In addition, the pallet base has at least one support foot, via which the transport container can be supported on a base. In other words, the transport container can be parked on a support floor via his support.

Such a transport container is used for example as part of a production of a motor vehicle as a charge carrier for receiving or transporting components. Usually several such transport containers are stacked on top of each other during transport. The transport container itself has only a small weight. However, if the shipping containers are loaded with at least one component or with several components, the respective transport containers with the components have a high total weight. When stacked, the lower transport container must support the load acting on the lower transport container from the upper or upper transport containers. The load that can be received or borne by the lower transport container is referred to as a surcharge.

The DE 42 16 419 A1 discloses a stackable pallet for large foil bags. The pallet has conical feet, in which stiffening rods are received during the transport of goods. The stiffening rods give lateral support to the foil bag.

Finally, the reveals DE 10 2005 034 544 A1 a collapsible transport container with a container edge and back feet. Flushed from the edge of the container to the back feet is a round iron attached as a deflector, such that between the bar iron and the foot creates a Gurtöse.

Object of the present invention is to develop a transport container of the type mentioned in such a way that a particularly low weight of the transport container and at the same time a particularly high load of the transport container can be realized.

This object is achieved by a transport container having the features of patent claim 1. Advantageous embodiments with expedient and non-trivial developments of the invention are specified in the remaining claims.

In order to create a transport container whose own weight can be kept very low and which has a particularly high load and thus can absorb particularly high, acting from above on the transport container loads destructive and damage-free, it is inventively provided that the support foot at least one Receiving, in which at least one support foot stiffening reinforcing element at least partially, in particular at least predominantly, is added. The reinforcing element acts as an inserted into the support foot seal, which is also referred to as a depositor. Through this composite of support foot and reinforcing element, a particularly advantageous, at least substantially linear force flow can be created via the support leg, so that the transport container can absorb and / or support even particularly high loads without destruction and damage. Forces can flow away at least substantially linearly via the aforementioned composite, so that buckling of the support leg can be prevented.

Preferably, the reinforcing element is formed as a support member separately formed and connected to the support foot, in particular screwed, component. As a result, for example, the reinforcing element particularly simple, time and cost solved by the support leg, replaced and thereby repaired. At the same time, a particularly low weight of the transport container can be represented, since in particular the Faltwandungsring and / or the pallet base can be formed by means of the so-called twin-sheet method.

To realize a particularly high stability and rigidity of the transport container, it is provided in one embodiment of the invention that at least one stiffening element is arranged between the inner skin and the outer skin. Such a stiffening element increases the carrying capacity of the Faltwandungsrings, so that the transport container has a particularly high payload and a particularly high static and dynamic load.

It is provided that the Faltwandungsring is supported on the reinforcing element via the stiffening element at least in the unfolded state. Thus forces acting on the reinforcing element from the folding wall ring or from the reinforcing element act at least substantially directly or directly on the reinforcing element. As a result, an at least substantially linear Force flow are created so that unfavorable, deflected force paths can be avoided. As a result, the risk of buckling and deformation of the transport container can be kept particularly low.

In the figures, the same or functionally identical elements are provided with the same reference numerals.

Fig. 1 and 2 show a designated as a whole with 10 transport container, which is used for example for the transport of components. The transport container 10 comprises a pallet base 12, a Faltwandungsring 14 and a lid 16, which in Fig. 1 is shown in sections.

The Faltwandungsring 14 is a manufactured in a twin-sheet process structure of a thermoformable plastic, which has an inner skin 22 and an outer skin 24. Between the inner skin 22 and the outer skin 24, which are respective walls of the Faltwandungsrings 14, may optionally be provided additional stiffening layers of the same plastic. The Faltwandungsring 14 can also still in Fig. 1 and 2 not shown film hinges that allow folding of individual wall sections. In this way, the Faltwandungsring 14 between an in Fig. 1 and 2 folded, unfolded state and a folded state to be folded. In the folded state, the Faltwandungsring 14 can be applied to the pallet base 12. In the unfolded state of the pallet base 12 circumferential Faltwandungsring 14 forms a directed in the normal direction of the pallet base 12 wall. Through this wall, a receiving space 26 of the transport container 10 is laterally limited. The receiving space 26 is in the normal direction down through the pallet base 12 and - when the lid 16 is placed on the Faltwandungsring 14 - limited in the normal direction upward through the lid 16. In the receiving space 26, at least one component to be transported can be arranged, so that the component can be transported safely and protected by means of the transport container 10.

How out Fig. 1 and 2 can be seen, the pallet base 12, which is also formed of a plastic, a plurality of support legs 28. About the support legs 28 of the transport container 10 can be supported on a substrate. This means that the transport container 10 can be parked on its feet 28 on a floor.

To realize an effective and efficient transport of several components can be provided that several transport containers 10 are stacked. For this purpose, a transport container 10 is set up on another transport container 10, so that the upper transport container 10 is supported via its support legs 28 on the lower transport container 10. Thus, the lower transport container 10 must support the total weight of the upper transport container 10, wherein the total weight includes the weight of the upper transport container 10 and the weight of at least one arranged in the upper transport container 10 component. This load originating from the upper transport container 10 and acting on the lower transport container 10 must absorb and support the lower transport container 10. The maximum load that can be borne by the lower transport container 10 is also referred to as a surcharge.

To realize a particularly high stability and rigidity of the respective transport container 10, it is preferably provided that between the inner skin 22 and the outer skin 24 at least one in Fig. 1 and 2 unrecognizable stiffening element of Faltwandungsrings 14 is arranged. This stiffening element can be in the form of a pipe or a profile and be formed from a plastic or a metallic material, in particular aluminum. Preferably, a plurality of stiffening elements between the inner skin 22 and the outer skin 24 are provided, so that a particularly high load capacity of the transport container 10 can be realized. The stiffening elements do not form a firm connection with the pallet base 12, so that they can be folded over when folding the Faltwandungsrings 14. As a result, the Faltwandungsring 14 can be easily spent in its folded state and thereby occupy a compact storage position.

The stiffening elements are for example stiffening struts and / or can already be inserted into the Faltwandungsring 14 during the twin-sheet process. Alternatively, it is possible to use the stiffening struts or stiffening elements later, so that, if necessary, a retrofitting of existing transport container is possible. At the same time, a particularly low weight of the transport container 10 itself can be realized, so that an outgoing from the transport container 10 itself and acting on the lower transport container 10 load can be kept low.

In order to be able to realize a particularly high load of the transport container 10, it is provided that - how very good Fig. 2 can be seen - the respective support leg 28 has a receptacle 30 in which in the assembled state of the transport container 10, a respective support leg 28 stiffening reinforcing element 32 is at least partially received. The Faltwandungsring 14 is at least in its unfolded state on the reinforcing element 32 can be supported. It is preferably provided that the Faltwandungsring 14 is at least in its unfolded state via the at least one stiffening element on the reinforcing element 32 can be supported. In other words, for example, between the inner skin 22 and the outer skin 24 arranged stiffening elements directly or directly on the respective reinforcing elements 32 act. As a result, an at least substantially linear or even force flow is created without deflections, so that the lower transport container 10 can derive the load or load acting on it particularly low down.

The respective reinforcing element 32 and the pallet base 12 are formed as separately formed and interconnected components. As a result, a particularly simple repair by replacement can be realized.

For example, the pallet base 12 is formed by deep drawing or thermoforming, wherein the support legs 28 are thermoformed. Here, the support legs 28 are formed as hollow feet, in which the respective reinforcing elements 32 can be inserted in the normal direction to the pallet base 12 from above. In order to realize a particularly firm connection between the respective reinforcing elements 32 and the support legs 28, the respective reinforcing elements 32 are screwed to the respective support feet 28. For this purpose, per support foot 28 and associated reinforcing element 32 is a plurality of Fig. 2 recognizable screws 34 used.

The respective reinforcement element 32, which is at least partially accommodated in the associated support leg 28, acts as a so-called foot seal, by means of which the associated support leg 28 is reinforced and has a particularly high stability. Preferably, the respective reinforcing element 32 is formed of polyethylene. Also, the pallet base 12 and / or the Faltwandungsring 14 may be formed of polyethylene. As a result, a simple recycling can be realized. However, reinforcing elements 32, pallet base 12 and Faltwandungsring 14 may consist of any other plastics; The reinforcing elements 32 may for example also consist of a metal.

Alternatively or additionally, it may be provided that the reinforcing elements 32 are positively connected to the respective support feet 28.

It has proven particularly advantageous if the respective reinforcing element 32 is produced as a plastic injection-molded part, that is to say by injection molding. In this way, a particularly high strength of the respective reinforcing element 32 can be realized. Furthermore, the total cost of the transport container 10 can still be kept low, especially in comparison to the use of injection molding for the production of the Faltwandungsrings 14 and the pallet base 12th

How out Fig. 3a can be seen, the respective reinforcing elements 32 may be received in the respective support legs 28 so that they are at least substantially flush with a receiving space 26 limiting top 37 of the pallet base 12 are arranged or set back from the top 37. This is also very good Fig. 3b to recognize.

Especially good Fig. 2 . 4a . 4b and 5a to 5d it can be seen that the respective reinforcing element 32 has a stiffening rib structure 36 with a plurality of stiffening ribs. The stiffening ribs engage in received in the support legs 28 state in corresponding recesses of the support legs 28 a. In this way, a particularly advantageous positioning of the reinforcing elements 32 relative to the support legs 28 can be realized.

Fig. 3b shows the pallet base 12 in a perspective bottom view, wherein Fig. 3c and 3d It can be seen that a lashing element 38 is provided on at least part of the support feet 28. The respective lashing element 38 has at least one lashing 39 and is held on the corresponding support leg 28. The tie-down element 38 is designed as a component formed by the corresponding support leg 28 and the reinforcing element 32 accommodated in the corresponding support leg 28 and held on the corresponding support leg 28. Preferably, the respective lashing element 38 is also made as an injection molded part made of polyethylene. To realize a particularly strong holder, the respective tie-down element 38 is connected to the reinforcing element 32 at least partially received in the corresponding support leg 28. How out Fig. 4a, 4b and 4c can be seen, the lashing element 38 is screwed to the associated reinforcing element 32. For this purpose, a plurality of screws 40, 42 are provided. How out Fig. 4a and 4b can be seen, the lashing element 38 is screwed laterally with the corresponding reinforcing element 32 by means of screws 40 from below and by means of the screw 42.

For this purpose, through openings are provided in a corresponding wall of the corresponding support leg 28, which are penetrated by the screws 40, 42. These passage openings are formed for example as bores. By screwing the lashing elements 38 with the reinforcing elements 32, a post-external bending or breaking out of the lashing elements 38 can be avoided.

The use of the twin-sheet method allows weight and cost savings compared to an injection molding process, wherein in particular the tool costs can be kept low. Preferably, the pallet base 12 is produced by means of the twin-sheet method. In order nevertheless to realize a particularly high fatigue strength of the twin-sheet components in the form of Faltwandungsrings 14, the pallet base 12 and optionally the lid 16, the Faltwandungsring 14 targeted by the reinforcing elements 32 and the pallet base 12, in particular its support legs 28, targeted by the reinforcing elements 32 locally stiffened or reinforced.

Fig. 5a and 5b In order to be able to screw the respective lashing element 38 to the corresponding reinforcing element 32, the respective lashing element 38 also has passage openings 44 for the screws 40, 42. From Fig. 5b . 5c and 5d can be seen, the lashing element 38 is itself designed as a lashing. This means that the lashing 39 is formed solely by the lashing element 38 and thus independently of the respective corresponding support leg 28.

By means of the lashing eyes 39, the transport container 10 can be secured on a loading area of a truck, especially if the loading area is not completely filled. By screwing the respective lashing element 38 with the solid and stable reinforcing element 32, a particularly high strength can be achieved, whereby, for example, a lashing with at least 500 decanewtons can be maintained. As a result, the transport container 10 can be secured particularly well. Because of the respective lashing element 38 outgoing loads act namely not directly on the twin-sheet components, but on the particularly strong, rigid and stable reinforcing element 32, whereby a particularly advantageous power flow is realized.
