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 suggests, for example a freight container having an aluminum alloy frame in which side walls and a roof of fiber reinforced plastic are inserted. 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.
- the DE 42 18 589 A1 describes a collapsible transport container, in which at least the side walls are connected to each other via a clip connection.
- a U-shaped rail surrounds a round profile element which extends over the entire longitudinal sides of the side wall.
- the roof element is a cover which partially surrounds the side walls and thus forms a frame enclosing the transport container.
- a side wall of the DE 42 18 589 A1 has a plate and a frame with four attachable profile strips.
- the profile strips in turn form a rectangle in the arranged state.
- the DE 10 2008 005 010 A1 in turn describes a collapsible transport container for goods, in particular air freight container, having a bottom, a lid, side walls, a rear wall and at least two doors. Profiles may be provided on the wall elements.
- the GB 2 273 542 A describes a freight container with elastic corner profiles, which are used to connect the side walls, are clipped into this.
- 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.
- At least one wall element which has a stiffening running from a wall corner to the diagonally opposite wall corner, comprising at least one additional wall layer (tarpaulin layer).
- stiffeners run from all four corners of the wall to the respective diagonally opposite wall corner, so that a total of a cross-shaped stiffening forms.
- the at least one stiffening is realized by a local increase of a number of layers (number of planets). 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 lightweight construction (Frame construction) and the absence of connecting means, such as rivets or screws.
- 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 release of a connection between floor and profile element via a rotation (of floor and profile element against each other) with subsequent removal of the floor and profile element from 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.
- spring and groove are formed such that the spring acts as a hook in the associated groove or is formed as a hook. This development is particularly simple in terms of design and allows a stable connection.
- a cross section of the spring when a cross section of the groove (other than a groove opening) is circular, a cross section of the spring may have a length (maximum length) in a longitudinal direction and a width (maximum width) in a width direction with the longitudinal direction perpendicular to the width direction, wherein the length is greater than the width (for example at least 1.1 times or at least 1.3 times or at least 1.6 times as large).
- a cross-section of the spring has a circular arc section and opposite the circular arc section a fulcrum.
- the spring can be particularly easily levered by rotation in the groove, which allows assembly and disassembly.
- an edge portion of the bottom plate and / or at least one of the edge portion of the bottom plate facing profile element edge portion (in cross section) is hook-shaped.
- a separate component for example, a separate hook
- the connection can thus be structurally extremely simple.
- At least one bottom plate edge portion of the bottom plate may be bent inwardly.
- at least one profile element edge section facing the bottom plate edge section can be bevelled downwards in the direction of the base plate.
- "inward” may mean that the bend is oriented toward a cargo receiving surface
- "inward” for a container 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.
- the bottom plate and / or at least one, preferably pultruded, profile element may be made at least in sections of fiber-reinforced carbon.
- weight can be saved.
- the hook construction is extremely stable due to the alignment of the fibers of the profile element along its longitudinal axis, against a tensile load by the bottom element.
- the present cargo receiving device can completely dispense with metallic components.
- the cargo receiving device may comprise an electromagnetic transmitter and / or receiver, in particular an RFID chip.
- this electromagnetic receiving and / or transmitting device can communicate particularly easily with a corresponding external transmitter or receiver. A disturbance by metallic components is avoided or at least reduced.
- the overall weight compared to known cargo receiving devices is significantly reduced again.
- a weight reduction of 35% or more seems possible, which could for example be around 640 kg per total load weight in a Boeing 747 compared to a load with known containers.
- a Boeing 747 in maximum capacity of about one-third aircraft, one-third passengers or cargo and about one-third fuel and in this form then has a take-off weight of about 408 tons, it comes to the result that about 130 tons of fuel are needed to transport 272 tons of aircraft and cargo.
- the cargo receiving device according to the invention can be saved on a flight in such a case about 320 kg of fuel. As a result, the CO 2 emissions can be significantly reduced again.

- a peripheral frame can be realized in a simple manner, which can be constructed entirely without gluing or screwing or the like. Sufficient stability is still ensured (although the holes 75 or corresponding support elements, such as diagonal straps can contribute).

Description
Die vorliegende Erfindung betrifft eine Frachtaufnahmeeinrichtung, wie Container, Palette oder dergleichen, insbesondere für das Beladen von Flugzeugen sowie ein Verfahren zur Herstellung einer FrachtaufnahmeeinrichtungThe 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
Für den effektiven Transport von Ladung in Flugzeugen sind Frachtcontainer und Frachtpaletten - also Frachtaufnahmeeinrichtungen - unverzichtbar, da sie ein schnelles Be- und Entladen des Flugzeugs ermöglichen. Die überwiegende Anzahl von kommerziell eingesetzten Flugzeugen kann eine Vielzahl von Frachtcontainern oder Frachtpaletten aufnehmen. Die meisten Container bzw. Paletten sind normiert, so dass diese unabhängig von dem für den Transport verwendeten Flugzeug eingesetzt werden können. Bis vor 10 Jahren wurden Frachtcontainer ausschließlich aus Aluminium hergestellt, wobei das Eigengewicht des Containers ca. 100 kg betrug. Die momentan verwendeten Container greifen teilweise auf leichtere Materialien zurück, so dass inzwischen Frachtcontainer mit einem Gewicht von ca. 60 kg verwendet werden. Es sollte offensichtlich sein, dass die Verringerung des Eigengewichts der verwendeten Container oder Paletten erhebliche finanzielle sowie ökologische Auswirkungen mit sich bringt. Ein Frachtcontainer ist beispielsweise in der

Diese Aufgabe wird durch eine Frachtaufnahmeeinrichtung gemäß Anspruch 1 gelöst.This object is achieved by a cargo receiving device according to
Ein wesentlicher Gedanke der Erfindung liegt darin, dass das Bodenelement durch das Vorsehen eines Hakens in das Profilelement eingehängt werden kann. Daraus resultiert eine konstruktiv einfache und dennoch sichere Verbindung. Montage und Demontage der Frachtaufnahmeeinrichtung sind erleichtert. Insbesondere kann auf eine irreversible Verklebung oder Verrastung verzichtet werden.An essential idea of the invention is that 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.
Erfindungsgemäß ist mindestens ein Wandelement vorgesehen, das eine von einer Wandecke zur diagonal-gegenüberliegenden Wandecke laufende Versteifung, umfassend zumindest eine zusätzliche Wandlage (Planenlage), aufweist. Bei dem Wandelement verlaufen von allen vier Wandecken Versteifungen zur jeweils diagonal-gegenüberliegenden Wandecke, so dass sich insgesamt eine kreuzförmige Versteifung ausbildet. Die mindestens eine Versteifung ist durch eine lokale Erhöhung einer Lagenanzahl (Planenlagenanzahl) realisiert. Durch die Versteifungen können Zuglasten über Eckpunkte aufgenommen werden, so dass diese (nicht mehr) über Rahmenprofile abgesetzt werden müssen. Insbesondere in Kombination mit dem zuvor beschriebenen Bodenelement wird eine Konstruktion erreicht, die äußerst leicht ist und einfach zu montieren. Vorgesehene Steckverbindungen oder Haken-Verbindungen werden durch die Versteifungen stabilisiert. Durch diese Maßnahme wird das mindestens eine Wandelement zu einem strukturell-verstärkenden Element der gesamten Frachtaufnahmeeinrichtung. Dies erlaubt eine leichte Konstruktion (Rahmenkonstruktion) sowie den Verzicht auf Verbindungsmittel, wie Nieten oder Schrauben.According to the invention, at least one wall element is provided, which has a stiffening running from a wall corner to the diagonally opposite wall corner, comprising at least one additional wall layer (tarpaulin layer). In the wall element stiffeners run from all four corners of the wall to the respective diagonally opposite wall corner, so that a total of a cross-shaped stiffening forms. The at least one stiffening is realized by a local increase of a number of layers (number of planets). 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. In particular, in combination with the floor element described above, a construction is achieved which is extremely lightweight and easy to assemble. Intended connectors or hook connections are stabilized by the stiffeners. By this measure, the at least one wall element becomes a structurally reinforcing element of the entire cargo receiving device. This allows a lightweight construction (Frame construction) and the absence of connecting means, such as rivets or screws.
Vorzugsweise ist eine Verbindung zwischen Bodenelement und Profilelement über ein Einstecken (des Boden- und/oder Profilelementes) mit anschließender Rotation (von Boden- und Profilelement gegeneinander) herstellbar. Alternativ oder zusätzlich ist das Lösen einer Verbindung zwischen Boden- und Profilelement über eine Rotation (von Boden- und Profilelement gegeneinander) mit anschließender Entfernung des Boden- und Profilelementes voneinander ermöglicht. Insgesamt wird dadurch eine zuverlässige Verbindung ermöglicht, die insbesondere die Montage bzw. Demontage erleichtert. Auch ohne das Vorsehen einer irreversiblen Verklebung oder Verrastung ist die Verbindung vergleichsweise zuverlässig (insbesondere aufgrund des Vorsehens des Hakens).Preferably, 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. Alternatively or additionally, the release of a connection between floor and profile element via a rotation (of floor and profile element against each other) with subsequent removal of the floor and profile element from each other. Overall, this makes a reliable connection possible, which facilitates in particular the assembly and disassembly. Even without the provision of irreversible gluing or latching, the connection is comparatively reliable (in particular due to the provision of the hook).
In einer konkreten Ausführungsform umfasst die Verbindungseinrichtung mindestens eine Nut und mindestens eine Feder. Die Nut kann beispielsweise im Profilelement vorgesehen sein (und/oder im Bodenelement). Die Feder ist vorzugsweise im Bodenelement vorgesehen. Alternativ oder zusätzlich ist mindestens eine Nut im Profilelement vorgesehen. Durch eine derartige Nut-Federverbindung zusammen mit dem Haken kann eine äußerst einfache Montage/Demontage realisiert werden.In a specific embodiment, 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. Alternatively or additionally, at least one groove is provided in the profile element. By such a tongue and groove joint together with the hook extremely simple assembly / disassembly can be realized.
Ein Querschnitt der Nut und/oder der Feder kann zumindest abschnittsweise rund, insbesondere kreisförmig ausgebildet sein. Dadurch können Profil- und Bodenelement besonders einfach gegeneinander rotiert werden, was die Montage/Demontage erleichtert. Ein Querschnitt der Nut ist vorzugsweise vollständig (abgesehen von einer Nutöffnung) kreisförmig.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).
Mindestens eine Feder und/oder mindestens eine Nut können asymmetrisch sein, so dass die Feder in einem vorbestimmten ersten Relativwinkel zur Nut in diese einführbar ist und in einem vorbestimmten zweiten (gegenüber dem ersten, verschiedenen) Relativwinkel mit der Nut verhakt ist. In dieser Ausführungsform sind Feder und Nut derart ausgebildet, dass die Feder in der zugeordneten Nut als Haken wirkt bzw. als Haken ausgebildet ist. Diese Weiterbildung ist insbesondere in konstruktiver Hinsicht besonders einfach und ermöglicht eine stabile Verbindung.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. In this embodiment, spring and groove are formed such that the spring acts as a hook in the associated groove or is formed as a hook. This development is particularly simple in terms of design and allows a stable connection.
Insbesondere wenn ein Querschnitt der Nut (abgesehen von einer Nutöffnung) kreisförmig ist, kann ein Querschnitt der Feder eine Länge (maximale Länge) in einer Längsrichtung aufweisen sowie eine Breite (maximale Breite) in einer Breitenrichtung, wobei die Längsrichtung auf die Breitenrichtung senkrecht steht, wobei die Länge größer als die Breite ist (beispielsweise mindestens 1,1mal oder mindestens 1,3mal oder mindestens 1,6mal so groß). Durch eine derart (im Querschnitt) längliche Feder kann die Verbindung mit der Nut einfach und sicher erfolgen.In particular, when a cross section of the groove (other than a groove opening) is circular, a cross section of the spring may have a length (maximum length) in a longitudinal direction and a width (maximum width) in a width direction with the longitudinal direction perpendicular to the width direction, wherein the length is greater than the width (for example at least 1.1 times or at least 1.3 times or at least 1.6 times as large). By such a (in cross-section) elongated spring, the connection with the groove can be done easily and safely.
Vorzugsweise weist ein Querschnitt der Feder einen Kreisbogenabschnitt auf und gegenüber dem Kreisbogenabschnitt einen Dreh-Abstütz-Vorsprung (fulcrum). Bei einer derartigen Ausführungsform kann die Feder besonders einfach durch Rotation in die Nut hineingehebelt werden, was eine Montage und Demontage ermöglicht.Preferably, a cross-section of the spring has a circular arc section and opposite the circular arc section a fulcrum. In such an embodiment, the spring can be particularly easily levered by rotation in the groove, which allows assembly and disassembly.
Vorzugsweise ist ein Randabschnitt der Bodenplatte und/oder mindestens ein dem Randabschnitt der Bodenplatte zugewandter Profilelement-Randabschnitt (im Querschnitt) hakenförmig. Durch die entsprechende Ausbildung des Randes kann ein separates Bauteil (beispielsweise ein separater Haken) entfallen. Die Verbindung kann somit konstruktiv äußerst einfach erfolgen.Preferably, an edge portion of the bottom plate and / or at least one of the edge portion of the bottom plate facing profile element edge portion (in cross section) is hook-shaped. By appropriate design of the edge, a separate component (for example, a separate hook) can be omitted. The connection can thus be structurally extremely simple.
Mindestens ein Bodenplattenrandabschnitt der Bodenplatte kann einwärts gebogen sein. Alternativ oder zusätzlich kann mindestens ein dem Bodenplattenrandabschnitt zugewandter Profilelementrandabschnitt nach unten in Richtung Bodenplatte abgeschrägt sein. Bei einer Ausführung der Frachtaufnahmeeinrichtung als Palette kann "einwärts bedeuten, dass die Biegung in Richtung einer Frachtaufnahmefläche orientiert ist. Bei einem Container kann "einwärts bedeuten, dass die Biegung in Richtung einer Mitte des Frachtaufnahmeraums orientiert ist. In jedem Fall kann dadurch eine stabile und insbesondere formschlüssige Ausbildung des Bodens erreicht werden. Der Materialaufwand ist dabei äußerst gering. Die Verbindung zwischen Bodenelement und Profilelement ist dennoch zuverlässig und sicher.At least one bottom plate edge portion of the bottom plate may be bent inwardly. Alternatively or additionally, at least one profile element edge section facing the bottom plate edge section can be bevelled downwards in the direction of the base plate. In one embodiment of the cargo receiving device as a pallet, "inward" may mean that the bend is oriented toward a cargo receiving surface, "inward" for a container may mean that the bend is oriented towards a center of the cargo receiving space. In any case, 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.
Die Bodenplatte und/oder mindestens ein, vorzugsweise pultrudiertes, Profilelement kann zumindest abschnittsweise aus faserverstärktem Kohlenstoff hergestellt sein. Dadurch kann einerseits Gewicht gespart werden. Insbesondere bei einer Herstellung durch Pultrusion ergibt sich der Vorteil, dass die Hakenkonstruktion durch die Ausrichtung der Fasern des Profilelementes entlang seiner Längsachse, gegenüber einer Zugbelastung durch das Bodenelement äußerst stabil ist.The bottom plate and / or at least one, preferably pultruded, profile element may be made at least in sections of fiber-reinforced carbon. As a result, on the one hand weight can be saved. Especially When produced by pultrusion, there is the advantage that the hook construction is extremely stable due to the alignment of the fibers of the profile element along its longitudinal axis, against a tensile load by the bottom element.
Die vorliegende Frachtaufnahmeeinrichtung kann vollständig auf metallische Komponenten verzichten. In einer konkreten Ausführungsform kann die Frachtaufnahmeeinrichtung einen elektromagnetischen Sender und/oder Empfänger, insbesondere einen RFID-Chip umfassen. Durch den Verzicht auf metallische Komponenten oder zumindest eine Reduktion des Anteils von metallischen Komponenten kann diese elektromagnetische Empfangs- und/oder Sendeeinrichtung besonders einfach mit einem entsprechenden externen Sender bzw. Empfänger kommunizieren. Eine Störung durch metallische Komponenten wird vermieden oder zumindest reduziert.The present cargo receiving device can completely dispense with metallic components. In a specific embodiment, the cargo receiving device may comprise an electromagnetic transmitter and / or receiver, in particular an RFID chip. By dispensing with metallic components or at least reducing the proportion of metallic components, this electromagnetic receiving and / or transmitting device can communicate particularly easily with a corresponding external transmitter or receiver. A disturbance by metallic components is avoided or at least reduced.
Durch die spezielle Bauweise der Frachtaufnahmeeinrichtung wird insgesamt das Gewicht gegenüber bekannten Frachtaufnahmeeinrichtungen nochmals erheblich reduziert. Eine Gewichtsreduktion von 35% oder mehr scheint möglich, was beispielsweise bei einer Boeing 747 nochmals rund 640 kg pro Gesamtladegewicht gegenüber einer Beladung mit bekannten Containern sein könnte. Wenn man davon ausgeht, dass eine Boeing 747 in maximaler Auslastung aus ca. einem Drittel Flugzeug, einem Drittel Passagiere bzw. Fracht und ca. einem Drittel Treibstoff besteht und in dieser Form dann ein Abfluggewicht von rund 408 Tonnen hat, so kommt man zum Ergebnis, dass ca. 130 Tonnen Treibstoff nötig sind, um 272 Tonnen Flugzeug und Ladung zu transportieren. Durch die erfindungsgemäße Frachtaufnahmeeinrichtung kann in einem solchen Fall rund 320 kg Treibstoff auf einem Flug gespart werden. Dadurch kann die CO2-Emission nochmals deutlich reduziert werden.Due to the special design of the cargo receiving device, the overall weight compared to known cargo receiving devices is significantly reduced again. A weight reduction of 35% or more seems possible, which could for example be around 640 kg per total load weight in a Boeing 747 compared to a load with known containers. Assuming that a Boeing 747 in maximum capacity of about one-third aircraft, one-third passengers or cargo and about one-third fuel and in this form then has a take-off weight of about 408 tons, it comes to the result that about 130 tons of fuel are needed to transport 272 tons of aircraft and cargo. By the cargo receiving device according to the invention can be saved on a flight in such a case about 320 kg of fuel. As a result, the CO 2 emissions can be significantly reduced again.

Der Rahmen 11 umfasst erste Profilelemente 17 und zweite Profilelemente 18, wobei sich die ersten Profilelemente 17 und die zweiten Profilelemente 18 insbesondere hinsichtlich Ihres Querschnittes unterscheiden. Die ersten Profilelemente 17 sind Bestandteil eines Bodenrahmens 19. Die zweiten Profilelemente 18 sind Bestandteile eines Seitenrahmens 20 sowie eines Deckenrahmens 21.The frame 11 comprises
In dem Bodenrahmen 19 sind Bodeneckelemente 22 integriert. An die Bodeneckelemente 22 können zwei erste Profilelemente 17 und ein zweites Profilelement 18 angesteckt werden. Der Seitenrahmen 20 bzw. der Deckenrahmen 21 umfassen Seiteneckelemente 23, an die drei zweite Profilelemente 18 angesteckt (angeschlossen) werden können.In the
Konkret kann der Boden 14 bzw. eine Bodenplatte in die Bodenaufnahmenut 26 eingeschoben werden. Aufgrund des Vorsehens der Bodenaufnahmenut können somit im Allgemeinen zusätzliche Verbindungsteile, wie beispielsweise Nieten, entfallen. Dadurch wird sowohl der konstruktive Aufbau als auch der Aufwand beim Zusammenbau erheblich reduziert.Specifically, the bottom 14 or a bottom plate can be inserted into the
Auch die Seitenwände 12a bis 12d können in die Seitenwandaufnahmenut 27 eingeschoben werden. Die Bodenaufnahmenut 26 und/oder Seitenwandaufnahmenut 27 hat vorzugsweise einen rundlichen Querschnitt und ist zur Aufnahme eines rundlichen Wulstes (siehe unten) des Bodens 14 oder einer der Seitenwände 12a bis 12d oder der Decke 13 geeignet.Also, the
Die Sitzschienenkonstruktion 28 hat einen länglichen Querschnitt mit einwärts gebogenen Haken 29 zum Zurückhalten von Verzurr-Ösen.The
Der Hohlraum 24 des ersten Profilelementes (siehe
Die Bodeneckelemente 22 können (in vertikaler Richtung) mit einem Flanschblech verlängert und/oder verbreitert werden (nicht in den Figuren zu sehen), insbesondere um die ersten Profilelemente mit den Bodeneckelementen 22 durch Schrauben verbinden zu können. Die Bodeneckelemente 22 (gegebenenfalls auch die Seiteneckelemente 23) können aus einem Verbundwerkstoff gebildet sein (insbesondere Faserverbundwerkstoff) oder gegebenenfalls auch aus einer Aluminiumlegierung (gegossen oder geschmiedet). Wenn die Eckelemente eine Metalllegierung umfassen, dann kann ein Korrosionsschutz zwischen den pultrudierten Profilelementen und den Eckelementen vorgesehen sein (da beispielsweise kohlenfaserverstärkter Kunststoff vergleichsweise aggressiv gegenüber Aluminium ist).The bottom corner elements 22 can be extended and / or widened (in the vertical direction) with a flange plate (not shown in the figures), in particular in order to be able to connect the first profile elements to the bottom corner elements 22 by means of screws. The bottom corner elements 22 (possibly also the side corner elements 23) may be formed from a composite material (in particular fiber composite material) or possibly also from an aluminum alloy (cast or forged). If the corner elements comprise a metal alloy, then corrosion protection can be provided between the pultruded profile elements and the corner elements (since, for example, carbon fiber reinforced plastic is comparatively aggressive towards aluminum).
Die Sitzschienenkonstruktion 28 kann Bohrungen (nicht in den Figuren zu sehen) umfassen (wobei die Bohrungen nachträglich eingearbeitet werden können und einen Durchmesser von 19 mm aufweisen können), um Verzurr-Ösen (single tiedown und double tie-down studs) befestigen bzw. einhaken zu können, beispielsweise wenn in dem Frachtcontainer schwere Lasten geflogen werden, welche noch zusätzlich im Container 10 verzurrt werden müssen. Bei Paletten könnten diese ebenfalls innen umlaufen, beispielsweise um Palettennetze an den Paletten zu befestigen. Bisher wurden dazu üblicherweise Aluminium-Teilstücke aufgeschraubt bzw. eingenietet. Beim vorliegenden Profilelement ist diese Sitzschienenkonstruktion 28 integriert und ebenfalls vorzugsweise aus pultrudiertem Faserverbundkunststoff (wie kohlenfaserverstärktem Kunststoff oder glasfaserverstärktem Kunststoff etc.).

Der Boden 14 umfasst eine erste Bodenschicht 39, eine zweite Bodenschicht 40 und eine dritte Bodenschicht 41. Die erste (unterste) Bodenschicht 39 ist vorzugsweise aus einer Aluminiumlegierung (insbesondere der 7075-Serie) und kann eine ausreichende Stützung gegenüber Transportrollen (PDU-Rollen) ermöglichen. Oberhalb der ersten Bodenschicht 39 kann die zweite Bodenschicht 40 aus faserverstärkten Kunststoff (wie kohlenstofffaserverstärkten Kunststoff und/oder glasfaserverstärkten Kunststoff) und/oder Aramid und/oder Kevlar gefertigt sein. Die zweite Bodenschicht 40 oder auch eine oberhalb der zweiten Bodenschicht liegende dritte Bodenschicht 41 kann eine (feine) Geflechtlage (Eisengeflechtlage) ausbilden, um gegebenenfalls eine elektromagnetische Abschirmung zu erreichen. Insgesamt können auch mehr als drei Bodenschichten vorgesehen sein. Eine Kombination aus mehreren der oben genannten Werkstoffe, insbesondere Faserwerkstoffe ist denkbar. Die Dicke der Bodenplatte kann 1,5 bis 4,5 mm, insbesondere (etwa) 3,2 mm betragen. Ein unterseitiges Metallblech (entspricht der ersten Bodenschicht 39) kann eine Dicke von 0,5 bis 1 mm, insbesondere (etwa) 0,75 mm aufweisen.The bottom 14 comprises a first
Ein Bodenrand 42 weist eine Aufbiegung 43 auf (in Richtung eines Inneren des Frachtcontainers). Dadurch kann ein günstiger (bündiger) Übergang in das erste Profilelement 17 erreicht werden. Weiterhin kann eine Delaminierung einer Metallauflage vermieden werden, wenn die Transportrollen (PDU-Rollen) Im Betrieb über eine Eckkante des Bodens fahren. Die Aufbiegung 43 verläuft parallel zu einer Schrägfläche 44 des ersten Profilelements 17. Wie in
Ein grundsätzlicher Aufbau der Seitenwände 12a bis 12d und der Decke 13 kann (ausschnittsweise)
Die Seitenwände 12a bis 12d sowie die Decke 13 können planenartig (bzw. als Plane) ausgebildet sein und einen Randwulst 45 (siehe
Die (als Planen ausgebildeten) Seitenwände 12a bis 12d sowie die Decke 13 können aus einem kohlstofffaserverstärkten Kunststoff, einem glasfaserverstärkten Kunststoff, aus Aramid und/oder Kevlar gefertigt sein. Andere Faserverbundwerkstoffe sind denkbar. In
Die mittlere Schicht 47 ist somit ausgebildet, um insbesondere (reine) Zugkräfte zwischen den Profilelementen (17, 18) zu übertragen. Die erste und dritte Seitenwandschicht 46, 48 ist vorzugsweise ausgebildet, um Eckpunkte der Seitenwände 12a bis 12d (oder Decke 13) zu stützen bzw. um Zugkräfte von Ecke zu Ecke zu übertragen.The
Die Seitenwandschichten 46 bis 48 können 0,1 bis 0,4 mm dick sein, insbesondere (etwa) 0,25 mm. Die Seitenwände 12a bis 12d bzw. Decke 13 können einen Gesamtdicke von ca. 0,5 bis 1 mm, vorzugsweise 0,75 mm aufweisen. Auch größere Dicken (insbesondere bei entsprechend hohen Gewichten) sind vorstellbar.The side wall layers 46 to 48 may be 0.1 to 0.4 mm thick, in particular (about) 0.25 mm. The
Vorzugsweise ist zumindest eine der drei Seitenwandschichten 46 bis 48 aus Aramid (Kevlar), insbesondere um eine hohe Schnittfestigkeit der Seitenwand zu erreichen. Dadurch wird die Sicherheit der Frachtaufnahmeeinrichtung weiter erhöht. Beispielsweise kann keine unbefugte Person (mit einfachen Mitteln) einen Schlitz in die Seitenwände 12a bis 12d einbringen und einen gefährlichen Gegenstand (beispielsweise eine Bombe) einwerfen. Außerdem kann durch Aramid (Kevlar) erreicht werden, dass die Frachtaufnahmeeinrichtung noch stabiler gegenüber Beschädigungen ist (beispielsweise bei einem Auffahrunfall mit einem Gabelstapler oder dergleichen).Preferably, at least one of the three side wall layers 46 to 48 of aramid (Kevlar), in particular to achieve a high cut resistance of the side wall. As a result, the safety of the cargo receiving device is further increased. For example, no unauthorized person can (by simple means) insert a slot in the
Grundsätzlich sind die Seitenwände 12a bis 12d bzw. die Decke 13 derart ausgebildet, dass (insbesondere über die Randwülste 45) an den Seitenwandrändern 49 Zugkräfte von den ersten und zweiten Profilelementen aufgenommen werden können (was zur Folge hat, dass die pultrudierten Profilelemente nicht oder nur bedingt auseinandergezogen werden können und die Struktur des Rahmens des Frachtcontainers 10 erhalten bleibt. Insbesondere die Kombination der speziellen Lagenanordnung (0 Grad/90 Grad-Lagen sowie -45 Grad/+45 Grad-Lagen) und der pultrudierten Ausführung der Profilelemente ermöglicht eine besonders leichte und dennoch stabile Konstruktion.Basically, the

Durch unterschiedliche Lagenrichtungen (-45 Grad/+45 Grad und 0 Grad/90 Grad) kann mit geringem Material- bzw. Gewichtsaufwand eine hochfeste Konstruktion erreicht werden, welche Lasten unmittelbar durch (reine) Zugkräfte über die Seitenwände bzw. die Decke in den Rahmen 11 (und umgekehrt) leitet. Auch ein Austausch einer beschädigten Seitenwand oder Decke ist einfach möglich, da auf feste Verbindungen, wie Nieten, verzichtet werden kann und die Seitenwände oder die Decke in großen Teilen einfach nur aus den Profilelementen gezogen werden muss (und gegebenenfalls an den Ecken abgeschraubt werden muss). Die erfindungsgemäße Steckkonstruktion des Rahmens 11 erleichtert weiter einen derartigen Austausch.The recessed
Die Eckplatten 59 können entweder ein (vorgefertigtes) Kunststoffteil (gegebenenfalls umfassend eine Faserkomponente) oder ein Metallteil (beispielsweise aus einer Aluminiumlegierung), insbesondere Metall-Stanzteil sein. Auch hier kann (bei der Verbindung eines Metall-, insbesondere Aluminium-Teils) auf einen Korrosionsschutz geachtet werden, insbesondere beim Einsatz von kohlenfaserverstärktem Kunststoff. In die Eckplatten 59 können bereits Bohrungen 60 (siehe
Eine Form zur Herstellung der Verbindung der jeweiligen Seitenwand 12a bis 12d oder Decke 13 mit der Eckplatte 59 kann einen Stift aufweisen mit einem konusförmigen Abschnitt, um Material einer der Seitenwandschichten 46 bis 48, insbesondere der ersten Seitenwandschicht 46 und/oder der dritten Seitenwandschicht 48 in die Bohrungen 60 bzw. deren Kantenbrüche 61 hineinzudrücken (siehe
In dem Ausschnitt gemäß
Der Boden 14 besteht aus zwei (mehrschichtigen) Lagen, die am Bodenrand 42 gefaltet sind, so dass sie übereinander liegen. Der Bodenrand 42 weist einen (nach oben ragenden) Randwulst 45 auf. Der Randwulst 45 hat eine Länge L sowie eine Breite B. Die Länge L ist größer als die Breite B (etwa 1,2mal so groß). Der Randwulst 38 weist (im Querschnitt) einen Kreisbogenabschnitt 69 auf, der mit einem Kreisbogenabschnitt 70 der Bodenaufnahmenut 26 des Profilelementes 17 korrespondiert. Gegenüber dem Kreisbogenabschnitt 69 weist der Querschnitt des Randwulstes 38 einen Vorsprung 71 auf, der dazu dient, den Randwulst 38 bzw. den Bodenrand 42 in die Bodenaufnahmenut 26 hinein zu bewegen (bei einer Rotation). Ein sich an ein distales Ende des Kreisbogenabschnittes 69 anschließender Abschnitt ist plan ausgebildet. Dadurch kann der Randwulst 38 vergleichsweise schmal gehalten werden, so dass er in die Bodenaufnahmenut 26 eingeführt werden kann. Dadurch wird die Verbindung von Bodenelement und Profilelement vereinfacht. Wird nun der Randwulst 38 (translatorisch) entlang einem Pfeil 72 in die Bodenelementaufnahmenut 26 hineinbewegt, resultiert die Relativstellung von Profilelement und Bodenelement, wie sie in
In einer konkreten Ausführungsform des Frachtcontainers liegen drei Bodeneckelemente 73 gemäß
An dieser Stelle sei darauf hingewiesen, dass alle oben beschriebenen Teile für sich alleine gesehen und in jeder Kombination, insbesondere den in den Zeichnungen dargestellten Details als erfindungswesentlich beansprucht werden. Abänderungen hiervon sind dem Fachmann geläufig.It should be noted at this point that all the above-described parts taken alone and in any combination, in particular the details shown in the drawings are claimed as essential to the invention. Variations thereof are familiar to the person skilled in the art.
