Definitions

  • the present invention relates to a cargo receiving device, such as containers, pallets or the like, in particular for loading aircraft and a method for producing a cargo receiving device.
  • freight containers and cargo pallets - ie cargo receiving facilities - are indispensable, as they allow a fast loading and unloading of the aircraft.
  • the vast majority of commercial aircraft can accommodate a variety of freight containers or cargo pallets.
  • Most containers or pallets are standardized so that they can be used independently of the aircraft used for transport.
  • freight containers were made exclusively of aluminum, with the weight of the container was about 100 kg.
  • the currently used containers are partly based on lighter materials, so that freight containers weighing around 60 kg are now being used. It should be obvious that reducing the dead weight of the containers or pallets used has a significant financial and environmental impact.
  • a freight container is in the DE 20 64 241 described.
  • the DE 696 16 182 T2 proposes a freight container having an aluminum alloy frame in which side walls and a roof made of fiber-reinforced plastic are used. The side walls and the roof are made as fiber webs of fiber-reinforced plastic.
  • a frame of carbon fiber reinforced plastic material is already mentioned in the aforementioned document.
  • a technical embodiment of such a freight container is the DE 696 16 182 T2 but not to be seen. Perhaps the frame should be made from the said knitted or knitted fabric by lamination or by winding.
  • a cargo receiving device e.g. a freight container or a pallet, in particular for the loading of aircraft, comprising at least one bottom element and at least one profile element which is connected to the bottom element, wherein at least one edge portion of the bottom element with the at least one profile element via a connecting device comprising a hook is detachably connected ,
  • the floor element can be suspended by providing a hook in the profile element. This results in a structurally simple, yet secure connection. Assembly and disassembly of the cargo receiving device are facilitated. In particular, can be dispensed with irreversible bonding or locking.
  • a connection between the floor element and profile element via an insertion (of the floor and / or profile element) with subsequent rotation (of floor and profile element against each other) can be produced.

  • the connecting device comprises at least one groove and at least one spring.
  • the groove may for example be provided in the profile element (and / or in the bottom element).
  • the spring is preferably provided in the bottom element.
  • at least one groove is provided in the profile element.
  • a cross section of the groove and / or the spring may be at least partially round, in particular circular. As a result, profile and floor element can be rotated particularly easily against each other, which facilitates assembly / disassembly.
  • a cross section of the groove is preferably completely circular (apart from a slot opening).
  • At least one spring and / or at least one groove may be asymmetrical, so that the spring is insertable into the groove at a predetermined first relative angle to the groove and is hooked to the groove at a predetermined second (relative to the first, different) relative angle.

  • at least one profile element edge section facing the bottom plate edge section can be bevelled downwards in the direction of the base plate.
  • “inwards” may mean that the bend is oriented towards a cargo receiving surface.
  • “inward” may mean that the bend is oriented towards a center of the cargo receiving space.
  • a stable and in particular positive formation of the soil can be achieved. The cost of materials is extremely low. The connection between floor element and profile element is still reliable and safe.

  • a core idea of this cargo receiving device is that by mating a plurality of profile elements in a simple manner, a frame can be formed, in which the bottom element can be accommodated. By dispensing with a plug connection to two adjacent profile elements, the frame can be closed in a particularly form-fitting manner. In particular, in combination with a hook construction, as described above, the bottom plate can be easily and reliably connected to the profile elements. Overall, a structurally simple assembly and disassembly is possible.
  • a plurality of corner elements are provided, which are connected with two profile elements via a plug connection, wherein an end corner element is provided which is connected to at most one profile element via a plug connection.

  • the at least one stiffening can be realized by a (local) increase of a number of plies (number of planks). Due to the stiffeners, tensile loads can be absorbed via corner points, so that they no longer have to be set down via frame profiles.
  • a construction is achieved which is extremely lightweight and easy to assemble.
  • the at least one wall element becomes a structurally reinforcing element of the entire cargo receiving device. This allows a simple construction (frame construction) and the absence of connecting means, such as rivets or screws.

  • the object is achieved by a cargo receiving device, such as a container, a pallet or the like, in particular for the loading of aircraft, wherein the cargo receiving device comprises at least one bottom element and at least one pultruded profile element made of fiber-reinforced plastic ,
  • An essential idea of this development or this independent aspect is to use a profile element made of fiber-reinforced plastic to stabilize the cargo receiving device, which is produced in the pultrusion process (pultrusion). Due to the pultrusion process, the profile element made of fiber-reinforced plastic is given a resistance, in particular to a bending load, which can not be achieved by conventional methods for processing fiber-reinforced plastic (with the same material expenditure). Overall, therefore, a stable construction of a cargo receiving device with less material is possible. As a result, the weight of a cargo receiving device can be significantly reduced again. Furthermore, an effective production is ensured.
