Description

The invention relates to a transport container with a pallet base and a Faltwandungsring 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 Faltwandungsring 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 Load 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 can be 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.

1 and 2 show you as a whole 10 designated transport container, which is used for example for the transport of components. The transport container 10 includes a pallet floor 12 , a folding wall ring 14 and a lid 16 which is in 1 is shown in sections.

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

How out 1 and 2 can be seen, the pallet floor points 12 , which is also made of a plastic, a plurality of support feet 28 on. About the support feet 28 is the transport container 10 can be supported on a surface. This means that the transport container 10 over his support feet 28 can be parked on a floor.

To realize an effective and efficient transport of several components can be provided that several transport containers 10 be stacked on top of each other. For this purpose, a transport container 10 to another transport container 10 placed so that the upper transport container 10 over his support feet 28 at the lower transport container 10 is supported. Thus, the lower transport container 10 the total weight of the upper transport container 10 support, the total weight, the weight of the upper transport container 10 as well as the weight of the at least one in the upper transport container 10 arranged component comprises. These from the upper transport container 10 outgoing and on the lower transport container 10 acting load must be the lower transport container 10 pick up and support. The from the lower transport container 10 maximum sustainable load is also referred to as ballast.

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 1 and 2 unrecognizable stiffening element of the 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 provided so that a particularly high load capacity of the transport container 10 is feasible. The stiffening elements do not make a firm connection with the pallet floor 12 one, allowing them to fold in the folding wall ring 14 can be transferred. This allows the Faltwandungsring 14 simply be spent in its folded state and thereby occupy a compact storage position.

The stiffening elements are for example stiffening struts and / or can already during the twin-sheet process in the Faltwandungsring 14 be inserted. 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 even be realized, leaving one from the transport container 10 self-outgoing and on the lower transport container 10 acting load can be kept low.

To now a particularly high load of the transport container 10 To be able to realize, it is provided that - how particularly well 2 recognizable - the respective support foot 28 a recording 30 in which, in the assembled state of the transport container 10 a the respective support foot 28 stiffening reinforcing element 32 at least partially included. The folding wall ring 14 is at least in its unfolded state on the reinforcing element 32 supportable. It is preferably provided that the Faltwandungsring 14 at least in its unfolded state, via the at least one stiffening element on the reinforcing element 32 is supportable. In other words, for example, those 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 the load or load acting on it can be deduced downwards particularly favorably.

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

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

The respective, in the associated support foot 28 at least partially received reinforcing element 32 acts as a so-called Fußplombe, through which the associated support foot 28 is reinforced and has a particularly high stability. Preferably, the respective reinforcing element 32 made of polyethylene. Also the pallet floor 12 and / or the Faltwandungsring 14 may be formed of polyethylene. As a result, a simple recycling can be realized. reinforcing elements 32 , Pallet floor 12 and folding wall ring 14 However, they can consist of any other plastics; the reinforcing elements 32 For example, they can also be made of a metal.

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

It has proven to be particularly advantageous if the respective reinforcing element 32 as a plastic injection molded part, that is, produced by injection molding. This allows a particularly high strength of the respective reinforcing element 32 will be realized. Furthermore, the total cost of the transport container can be 10 still keep low, especially in comparison to the use of injection molding for the production of the Faltwandungsrings 14 and the pallet floor 12 ,

How out 3a can be seen, the respective reinforcing elements 32 such in the respective support feet 28 be included that they are at least substantially flush with the recording room 26 limiting top 37 of the pallet floor 12 are arranged or opposite the top 37 are set back. This is also very good 3b to recognize.

Especially good 2 . 4a . 4b and 5a to 5d it can be seen that the respective reinforcing element 32 a stiffening rib structure 36 having a plurality of stiffening ribs. The stiffening ribs engage in the support feet 28 recorded state in corresponding recesses of the support legs 28 one. This allows a particularly advantageous positioning of the reinforcing elements 32 relative to the support feet 28 will be realized.

3b shows the pallet floor 12 in a perspective bottom view, wherein 3c and 3d it can be seen that on at least part of the support feet 28 a lashing element 38 is provided. The respective lashing element 38 has at least one lashing 39 and is at the corresponding support foot 28 held. The lashing element 38 is here as one of the corresponding support foot 28 and in the corresponding support leg 28 received reinforcing element 32 trained and at the corresponding support foot 28 held member formed. Preferably, the respective lashing element 38 also made as an injection molded polyethylene. To realize a particularly strong holder is the respective lashing element 38 with the corresponding support foot 28 at least partially received reinforcing element 32 connected. How out 4a . 4b and 4c is recognizable, is the lashing element 38 with the associated reinforcing element 32 screwed. For this purpose, a plurality of screws 40 . 42 intended. How out 4a and 4b is recognizable, the lashing element 38 with the corresponding reinforcing element 32 by means of screws 40 from below and by means of the screw 42 screwed on the side.

For this purpose, in a corresponding wall of the corresponding support leg 28 Through openings provided, which by the screws 40 . 42 be penetrated. These passage openings are formed for example as bores. By screwing the lashing elements 38 with the reinforcing elements 32 may be an outward bending or breaking out of the lashing elements 38 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 floor is 12 produced by means of the twin-sheet process. Nevertheless, a particularly high fatigue strength of the twin-sheet components in the form of Faltwandungsrings 14 , the pallet floor 12 and optionally the lid 16 To realize is the Faltwandungsring 14 targeted by the reinforcing elements 32 and the pallet floor 12 , especially its support feet 28 , targeted by the reinforcing elements 32 locally stiffened or strengthened.

5a and 5b show the respective lashing element 38 , To the respective lashing element 38 on the corresponding reinforcing element 32 to be able to screw, also has the respective lashing element 38 Through openings 44 for the screws 40 . 42 on. From 5b . 5c and 5d is recognizable, is the lashing element 38 even formed as lashing. This means that the lashing eye 39 solely by the lashing element 38 and thus independent of the corresponding support foot 28 is trained.

By means of lashing eyes 39 can the transport container 10 be secured on a cargo bed of a truck, especially if the loading area is not completely filled. By the screw connection of 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. This allows the transport container 10 be secured very well. From the respective lashing element 38 outgoing loads do not act directly on the twin-sheet components, but on the particularly strong, stiff and stable reinforcing element 32 , whereby a particularly advantageous power flow is realized.
