Definitions
- the invention relates to a container, which is used in particular for receiving, for storing, for storage and / or transport of a good as at least one object or a liquid.
- a container for transport by land, water and / or air. It is possible that this is an air freight container or storage container.
- the company VRR Air Cargo Equipment has developed on behalf of the Spanish Air Force an air cargo container, in which the interior is limited by a rigid metallic housing. On the outside of the housing extinguishers are fixed, which in case of fire, a extinguishing agent in the container injected (see http://www.vrr-aviation.com/products/military/aay-container-fire-containment-container-(fcc )).
- DE-OS 1 786 205 discloses an air cargo container consisting of a flat bottom plate and a flexible, heat insulating, air mattress inflatable wall. This wall can be folded in unladen condition of the container, so that the container occupies a small space, which exceeds the volume of the bottom plate at most slightly. If the container to be loaded, the walls are erected by blowing compressed gas into the air mattress-like walls.
- the container may have a loading opening which can be closed with a zipper.
- An upper curvature of the wall may be adapted to the curvature of a cargo hold of the aircraft, and the floor panel may have attachment means to anchor it to the cargo hold of the aircraft.
- Further support means may be provided, such as a support in the form of a metal or plastic tube which can be inserted between the base plate and the ceiling wall, in particular near a feed opening.
- the wall may be formed gas-impermeable, for example with a rubberized fabric.
- hose-like sections may be provided, which may be filled with a gas or a gas mixture. The document also mentions that such a hose can be filled with nitrogen, which should suffocate a possibly occurring fire in a momentous plane crash.
- DE 26 56 639 A1 discloses a collapsible container for liquid or solid cargo with a bag or hose-like wall, which can be clamped by a flexible, folding or extendable support structure between a bottom and a cover plate. Proposed here is to provide the support structure with a resistance to fire or with self-extinguishing properties in the presence of fire and with a high temperature resistance.
- DE 103 18 975 B3 discloses a method for controlling a fire occurring in a closed space of an aircraft, in particular in an overhead luggage rack in the passenger area or in a container in the cargo hold of the aircraft. While the space protected by the fire-fighting method is intended to be hermetically sealed so that a fire emanating from it quickly stifles, unwanted leaks in these spaces result in smoke from the rooms leaking through the leaks and fire favoring supply of air or oxygen takes place.
- the document proposes, in the vicinity of expected leakage points, a heat-frothing and volume-increasing refractory Provide material. If there is a fire, the material foams up, whereby an automated sealing of unwanted leaks occurs and the supply of air or oxygen through the leak point is reduced or prevented.
- DE 103 58 978 A1 discloses a fire protection element, which should be compacted compactly in a storage condition. If there is a fire, the fire protection element should be thrown into the fire, where it should unfold automatically and form a fire blanket. Such formed, automatically expanding fire blanket should be used for fires in the home, in the home, in buildings, in motor vehicles, in the forest, in chemistry, burning oil, burning electronic components and smoldering fires. To realize the automatic expansion of the space-saving compacted storage condition of the fire blanket, the document proposes to equip the fire protection element with an expander whose expansion is started by means of a trigger.
- the trigger is activated manually during ejection, by the impact of the fire protection element, directly by the heat effect of the fire, automatically by a distance fuze, by radio or by a temperature, radiation or smoke sensor.
- the energy of the expander results from an elastic bias, a pressure energy from pyrotechnic gas generators, from compressed gas cartridges, the throw energy, centrifugal forces or an Archimedean buoyancy.
- the fire blanket is made of an electrically non-conductive material such as ceramic or plastic, whereby a surface coating can be used to influence a radiation behavior.
- a weight-related, automatic adaptation of the fire blanket to a contour of the fire can be done, to which the expander can lose its inherent rigidity due to the action of heat or automatically after the expansion.
- the expander additionally stiffened after the unfolding, to form with the fire blanket a self-supporting wall, with which a flame front stopped or distracted, limited to a fire or an object to be protected is to be included.
- a flame front stopped or distracted limited to a fire or an object to be protected is to be included.
- the fire protection element has a fire blanket, which is clamped over a frame-like steel strip.
- the fire blanket and steel strip are rolled up and secured by a flammable strip in the form of the roll. If the fire blanket thrown as such a role in a fire, the flammable tape dissolves, so that the expansion of the steel strip automatically spans the fire blanket.

- the present invention has for its object to propose a container, which offers alternative or improved possibilities for fighting a fire in an interior of the container.
- the container should be simple and inexpensive to produce while high effectiveness of fire fighting.
- the present invention is based on the recognition that the emergence and maintenance of a fire in a container on the one hand requires, for example, a liquid or solid kiln and on the other hand, an oxidizing agent.
- the kiln can hereby be formed by the container itself, but this can be ruled out by a suitable choice of material.
- the firing material can be formed by the material to be stored, stored, stored or transported in the container.
- the oxidizing agent effective in the case of a fire is usually a fluid present in the interior of the container, in particular oxygen, of air arranged in the interior.
- the invention turns away from the prejudice that a volume of an oxidant disposed in an interior of a container, and thus a potential for the extent of a fire being formed, must be accepted as fixed for the emergence of a fire.
- the container is formed with an interior which is bounded by a wall.
- the interior space is largely lockable against entry of air from the outside, and "substantially lockable" is also intended to include an air exchange rate which is insufficient for a supply of air from outside to the interior to an extent sufficient to support a fire or uphold.
- the measures according to the invention may not require the use of an extinguishing agent, which could reduce the value of the goods in the container or render them unusable and / or make it impossible to reuse the container (it being entirely conceivable that in addition to the measures according to the invention further measures such as the use of an extinguishing agent or other of the measures mentioned above takes place).
- the second operating position of the wall is in particular taken automatically when a fire is created in the container or its size exceeds a minimum level or a minimum duration.
- the first index “I” stands for “interior” and “F” for "fluid”, ie in particular the air
- the second index "1” indicates the first operating position, ie the normal case without fire
- the index "2" indicates the second operating position for the occurrence of a fire.
- the variability of the wall from the first operating position to the second operating position via the operating position change member may be arbitrary.
- the operating position changing member may include a sensor for detecting a developing fire, for example, based on smoke generation and / or heat generation, an actuator automatically operated in the case of detecting a fire by said sensor, and one for reducing Having the volume of the interior movable wall.
- the wall bounding the interior is formed with a flexible, not inherently rigid wall material.
- the flexible, non-rigid wall material allows the change from the first operating position of the wall to the second operating position of the wall.

- the wall material can be glued to this support framework, attached or otherwise held.
- the wall material can be held in the first operating position with holding devices in the form of tensioning devices or deployment devices, in particular in the manner of tent poles.
- the holding action of the holding device can then be canceled or at least reduced via the operating position changing element. This makes it possible that the flexible, non-rigid wall takes the second operating position.
- the holding device may lose its retaining action by developing smoke or heat, in particular by the smoke or heat reducing or eliminating a sticking action or weakening the tensioning or unfolding device by the heat or smoke.
- the energy for effecting the change in operating position from the first operating position to the second operating position may be provided by any power source and any release mechanism or actuator.
- the operating position change member is formed with an elastic deformation element, which at least partially provides the energy for changing the operating position.
- the elastic bias of the deformation element is greater when the wall is in the first operating position, as if the wall is in the second operating position.
- the wall is transferred from the first operating position to the second operating position, whereby the elastic deformation element is also responsible (at least partially) for pushing out the fluid disposed in the interior through the check valve element to the outside.
- the elastic deformation element may be any discrete or continuous deformation element, for example a spring element.
- thermoplastic deformation element can be used, in which stresses are frozen, which are released when a threshold value of a temperature in the interior of the container is exceeded.
- the transfer of the wall from the first operating position into the second operating position can be brought about, at least in part, via the dead weight of the wall material, which then also causes the expulsion of the fluid through the check valve element.
- the flexible wall in the first operating position, the flexible wall may be kept at a distance above a bottom of the container and the goods in the container.
- the flexible wall material drops from above onto the bottom plate of the container and the goods, which can also be comparable to the laying of a fire blanket from above.
- the weight of the wall material causes the wall material fits tightly to the burning goods and little or no oxidant between wall material and the goods remains because it is removed with the sinking of the wall material from the interior of the container through the check valve element. It is understood that additional weights can also be used for the above-described lowering of the wall material.
- the housing, wall and floor construction for the container according to the invention is arbitrary.
- a fire-resistant pallet use as a base plate as this in DE 602 16 873 B2 is described or it can be a structure of the container according to the input-listed documents.
- the interior is bounded by a wall material formed by a tent-like tarpaulin. This is spanned by a holder formed by tent-like frames holding device for specifying the volume in the first operating position.
- This is a particularly simple and inexpensive design, which also allows a space-saving transport of the container when no goods are to be transported in this.
- some or all design features of a tent-like constructed cargo container can be used in addition to the above-mentioned inventive measures, as in the non-prepublished patent application DE 10 2009 046 409.3-22 the applicant are described.

- Fig. 2 shows the container 1 in the second operating position.
- the effect of the holding device 6 is canceled or reduced, ie the tent clips 3 no longer hold the tarpaulin 4 in the unfolded state Fig. 1 , Rather, the tarpaulin 4 has dropped to the bottom plate 2 and the goods 8 and has applied to this.

- shrinkage ratios of more than 3: 1, 5: 1, 8: 1 or 10: 1 can be realized.
- the threshold value of the temperature causing the shrinkage may be between 65 ° and 125 °, for example between 80 ° and 110 ° or above 90 °, but in some cases also above or below it.
- the container for example, according to an air cargo container according to the non-prepublished patent application DE 10 2009 046 409.3 be educated.
- the support linkage formed with the tent poles 3 is made of a thermoplastic which has been stretched as previously described with frozen strains.
- the production of such a support linkage can be done relatively easily by extrusion, which also corresponds to the production process for stretched thermoplastics.
- a textile or polymeric material is used, in which, as in Fig. 1 shown, both from the vertex of the container starting star-shaped and equatorial, ie in the circumferential direction around the container 1, deformation elements 5 are introduced from stretched thermoplastic or glued or sewn onto this.
- the check valve elements 10 may be designed as check valves, for example made of textile or polymeric material, or as comparable check valves.
- the threshold value of the shrinkage temperature of the thermoplastic is exceeded, the return orientation of the thermoplastic in the support frame, in particular the tent poles 3 and the deformation elements 5, is automatically set without additional manual intervention. As a result, the wall 14 is shirred and there is a reduction in the volume in the interior 7.
- the threshold of the shrinkage temperature of the thermoplastic used is to be chosen such that it is slightly above the maximum expected during operation of the container 1 temperature.
- the container 1 according to the invention may be designed to be maintenance-free. Damage to a wall 14 may have only a small influence on the fire-extinguishing function due to the large number of possible deformation elements 5 or thermoplastic tapes.
- Fig. 5 finds an adhesive layer 17 insert, which greatly reduces its adhesive force under the action of heat at a temperature in the vicinity of the threshold value of the shrinkage temperature of the deformation elements 5.
- the wall 14, in particular the tarpaulin 4 can be designed to be very thin, so that a container 1 with a low weight or in the case of the use of the retrofit kit 13 only a small additional weight for the conventional container 12 results. Any additional weight, however, can be saved directly elsewhere, since the use of an additional fire extinguishing system, for example in a cargo hold of an aircraft, may be unnecessary.
- Both for the tent-like design of the container 1 according to Fig. 1 and 2 as well as for the retrofit solution with the retrofit kit 13 according to Fig. 3 to 5 can be present in the wall 14 openings for loading and unloading, which are formed for example with zippers, Velcro or other form-flexible compounds and are formed as airtight or with reduced air exchange rate.

Abstract
Description
Die Erfindung betrifft einen Container, der insbesondere zur Aufnahme, zur Bevorratung, zur Lagerung und/oder zum Transport eines Guts wie mindestens eines Gegenstands oder einer Flüssigkeit dient. Beispielsweise handelt es sich um einen Container für einen Transport auf dem Land-, Wasser- und/oder Luftweg. Möglich ist, dass es sich um einen Luftfrachtcontainer oder Lagercontainer handelt.The invention relates to a container, which is used in particular for receiving, for storing, for storage and / or transport of a good as at least one object or a liquid. For example, it is a container for transport by land, water and / or air. It is possible that this is an air freight container or storage container.
Kommt es in einem Container zu einem Brand des Inhalts des Containers und/oder des Containers selbst, führt dies zu einem materiellen Schaden, da der Inhalt des Containers hierdurch unbrauchbar werden kann. Weiterhin besteht die Gefahr, dass sich ein Brand in dem Container negativ auf die Umgebung auswirkt, insbesondere durch Ausbreitung des Feuers oder durch Schaffung einer Wärmequelle, wodurch Folgeschäden verursacht werden können. Schließlich kann das Feuer auch durch eine Rauchentwicklung zu Schäden oder gesundheitlichen Beeinträchtigungen bis hin zu einem Ersticken führen.If the contents of the container and / or the container itself burn in a container, this will result in material damage as the contents of the container may become unusable as a result. Furthermore, there is a risk that a fire in the container adversely affects the environment, in particular by spreading the fire or by creating a heat source, which can be caused by consequential damage. Finally, the smoke can also lead to smoke or damage to health or damage to a suffocation.
Das Unternehmen VRR Air Cargo Equipment hat im Auftrag der spanischen Luftwaffe einen Luftfrachtcontainer entwickelt, bei welchem der Innenraum durch ein starres metallisches Gehäuse begrenzt ist. An dem Gehäuse sind außenseitig Feuerlöscher befestigt, welche im Fall eines Feuers ein Löschmittel in dem Container injizieren (vgl. http://www.vrr-aviation.com/products/military/aay-container-fire-containment-container-(fcc)).The company VRR Air Cargo Equipment has developed on behalf of the Spanish Air Force an air cargo container, in which the interior is limited by a rigid metallic housing. On the outside of the housing extinguishers are fixed, which in case of fire, a extinguishing agent in the container injected (see http://www.vrr-aviation.com/products/military/aay-container-fire-containment-container-(fcc )).
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Container vorzuschlagen, welcher alternative oder verbesserte Möglichkeiten für die Bekämpfung eines Feuers in einem Innenraum des Containers bietet. Insbesondere soll der Container einfach gestaltet sein und kostengünstig herstellbar sein bei gleichzeitiger hoher Effektivität der Feuerbekämpfung.The present invention has for its object to propose a container, which offers alternative or improved possibilities for fighting a fire in an interior of the container. In particular, the container should be simple and inexpensive to produce while high effectiveness of fire fighting.
Die Aufgabe der Erfindung wird erfindungsgemäß mit einem Container mit den Merkmalen des unabhängigen Patentanspruchs 1 gelöst. Weitere Ausgestaltungen des erfindungsgemäßen Containers ergeben sich entsprechend den abhängigen Patentansprüchen 2 bis 8. Eine weitere Lösung der der Erfindung zugrundeliegenden Aufgabe ist gegeben durch einen Nachrüstsatz für einen Container entsprechend dem nebengeordneten Patentanspruch 9.The object of the invention is achieved with a container having the features of
Die vorliegende Erfindung basiert auf der Erkenntnis, dass die Entstehung und Aufrechterhaltung eines Feuers in einem Container einerseits ein beispielsweise flüssiges oder festes Brenngut erfordert und andererseits ein Oxidationsmittel. Das Brenngut kann hierbei von dem Container selbst gebildet sein, was aber durch geeignete Materialwahl ausgeschlossen werden kann. Weiterhin kann das Brenngut von dem in dem Container aufgenommenen, zu bevorratenden, zu lagernden oder zu transportierenden Gut gebildet sein. Hingegen handelt es sich bei dem im Fall eines Feuers wirksamen Oxidationsmittel üblicherweise um ein in dem Innenraum des Containers vorhandenes Fluid, insbesondere Sauerstoff von in dem Innenraum angeordneter Luft.The present invention is based on the recognition that the emergence and maintenance of a fire in a container on the one hand requires, for example, a liquid or solid kiln and on the other hand, an oxidizing agent. The kiln can hereby be formed by the container itself, but this can be ruled out by a suitable choice of material. Furthermore, the firing material can be formed by the material to be stored, stored, stored or transported in the container. On the other hand, the oxidizing agent effective in the case of a fire is usually a fluid present in the interior of the container, in particular oxygen, of air arranged in the interior.
Gemäß
Basierend auf der zuvor erläuterten Erkenntnis wendet sich die Erfindung von dem Vorurteil ab, dass ein Volumen eines in einem Innenraum eines Containers angeordneten Oxidationsmittels, und damit ein Potential für das Ausmaß eines sich ausbildenden Feuers, für das Entstehen eines Feuers als fest vorgegeben hinzunehmen ist.Based on the above-explained knowledge, the invention turns away from the prejudice that a volume of an oxidant disposed in an interior of a container, and thus a potential for the extent of a fire being formed, must be accepted as fixed for the emergence of a fire.
Erfindungsgemäß ist der Container mit einem Innenraum ausgebildet, der durch eine Wandung begrenzt ist. Der Innenraum ist gegenüber einem Eintritt von Luft von außen weitestgehend abschließbar, wobei "weitestgehend abschließbar" auch eine Luftwechselrate umfassen soll, welche unzureichend ist für eine Nachfuhr von Luft von außen zu dem Innenraum in einem Ausmaß, welches ausreichend ist, um ein Feuer zu unterstützen oder aufrechtzuerhalten.According to the invention, the container is formed with an interior which is bounded by a wall. The interior space is largely lockable against entry of air from the outside, and "substantially lockable" is also intended to include an air exchange rate which is insufficient for a supply of air from outside to the interior to an extent sufficient to support a fire or uphold.
Für den erfindungsgemäßen Container ist das Volumen des Innenraums nicht konstant. Vielmehr besitzt die den Innenraum begrenzende Wandung eine erste Betriebsstellung sowie eine zweite Betriebsstellung:
- In der ersten Betriebsstellung, welche mit dem nicht brennenden Normalzustand des Containers korreliert, besitzt der von der Wandung begrenzte Innenraum ein Volumen Vl1. Sind in dem Innenraum Güter oder Gegenstände mit einem Volumen VG angeordnet, verbleibt in dem Innenraum ein Restvolumen für ein Fluid wie Luft mit einem Fluidvolumen VF1, wobei VF1 = Vl1 - VG gilt.
- Hingegen ist in der zweiten Betriebsstellung der Wandung das Volumen des von der Wandung begrenzten Innenraums gegenüber dem Volumen Vl1 in der ersten Betriebsstellung verringert auf ein Volumen Vl2 < Vl1. Bei Annahme unveränderten Volumens VG verbleibt zwischen Wandung und Gütern oder Gegenständen ein verringertes Fluidvolumen VF2. Dies hat zur Folge, dass in der zweiten Betriebsstellung für ein Feuer lediglich ein entsprechend reduziertes Volumen des Oxidationsmittels zur Verfügung steht.
- In the first operating position, which correlates with the non-burning normal state of the container, the wall bounded by the interior space has a volume V l1 . If goods or objects with a volume V G are arranged in the interior space, a residual volume for a fluid, such as air, with a fluid volume V F1 remains in the interior, where V F1 = V l1 -V G.
- On the other hand, in the second operating position of the wall, the volume of the inner space bounded by the wall relative to the volume V l1 in the first operating position is reduced to a volume V l2 <V l1 . Assuming unchanged volume V G remains between wall and goods or objects a reduced fluid volume V F2 . This has the consequence that only a correspondingly reduced volume of the oxidizing agent is available in the second operating position for a fire.
Die Veränderung von der ersten Betriebsstellung zur zweiten Betriebsstellung wie folgt realisiert:
- Erfindungsgemäß ist ein Rückschlagventilelement vorgesehen. Das Rückschlagventilelement ist derart in den Container integriert, dass dieses eine Strömung von Fluid von außen in den Innenraum sperrt, während eine Strömung von Fluid aus dem Innenraum nach außen ermöglicht ist.
- According to the invention, a check valve element is provided. The check valve element is integrated in the container such that it blocks a flow of fluid from the outside into the interior, while a flow of fluid from the interior is made possible to the outside.
Der erfindungsgemäße Container verfügt darüber hinaus über ein Betriebsstellungsänderungsorgan. Dieses überführt im Fall eines Feuers automatisch die Wandung von der ersten Betriebsstellung in die zweite Betriebsstellung, so dass dieses die Verringerung des Fluidvolumens von VF1 auf VF2 bewirkt. Dies erfolgt durch Ausschieben des verbrennungsfördernden Fluids, also des Differenzvolumens VD = VF1 - VF2, aus dem Innenraum über das Rückschlagventilelement nach außen.The container according to the invention also has a Betriebsstellungsänderungsorgan. This automatically transfers the wall from the first operating position to the second operating position in the event of a fire, so that this causes the reduction of the fluid volume from V F1 to V F2 . This is done by pushing out the combustion-promoting fluid, ie the difference volume V D = V F1 - V F2 , from the interior via the check valve element to the outside.
Erfindungsgemäß kann durch Reduktion des verbrennungsfördernden Fluids im Innenraum des Containers die Brandentstehung und Brandentwicklung signifikant gehemmt werden. Von Vorteil ist, dass die erfindungsgemäßen Maßnahmen unter Umständen nicht den Einsatz eines Löschmittels erfordern, welches das Gut in dem Container im Wert mindern oder unbrauchbar machen könnte und/oder eine Wiederverwertung des Containers unmöglich machen würde (wobei durchaus denkbar ist, dass ergänzend zu den erfindungsgemäßen Maßnahmen weitere Maßnahmen wie der Einsatz eines Löschmittels oder anderer der eingangs genannten Maßnahmen erfolgt).According to the invention, by reducing the combustion-promoting fluid in the interior of the container, the formation of fire and the development of fire can be significantly inhibited. It is advantageous that the measures according to the invention may not require the use of an extinguishing agent, which could reduce the value of the goods in the container or render them unusable and / or make it impossible to reuse the container (it being entirely conceivable that in addition to the measures according to the invention further measures such as the use of an extinguishing agent or other of the measures mentioned above takes place).
Die zweite Betriebsstellung der Wandung wird insbesondere automatisch eingenommen, wenn ein Feuer in dem Container entsteht oder dessen Größe ein Mindestausmaß oder eine Mindestdauer überschreitet. In den verwendeten Indizes steht der erste Index "I" für "Innenraum" und "F" für "Fluid", also insbesondere die Luft, während der zweite Index "1" die erste Betriebsstellung, also den Normalfall ohne Feuer, kennzeichnet und der Index "2" die zweite Betriebsstellung für das Auftreten eines Feuers kennzeichnet.The second operating position of the wall is in particular taken automatically when a fire is created in the container or its size exceeds a minimum level or a minimum duration. In the indices used, the first index "I" stands for "interior" and "F" for "fluid", ie in particular the air, while the second index "1" indicates the first operating position, ie the normal case without fire, and the index "2" indicates the second operating position for the occurrence of a fire.
Die Veränderbarkeit der Wandung von der ersten Betriebsstellung in die zweite Betriebsstellung über das Betriebsstellungsänderungsorgan kann beliebig sein. Um hier lediglich ein mögliches Beispiel zu nennen, kann das Betriebsstellungsänderungsorgan einen Sensor zur Detektion eines sich entwickelnden Feuers, beispielsweise basierend auf einer Rauchentwicklung und/oder einer Wärmeentwicklung, einen im Fall einer Detektion eines Feuers durch den genannten Sensor automatisiert betätigten Aktuator und eine zur Verringerung des Volumens des Innenraums bewegbare Wand aufweisen.The variability of the wall from the first operating position to the second operating position via the operating position change member may be arbitrary. To mention just one possible example herein, the operating position changing member may include a sensor for detecting a developing fire, for example, based on smoke generation and / or heat generation, an actuator automatically operated in the case of detecting a fire by said sensor, and one for reducing Having the volume of the interior movable wall.
In weiterer Ausgestaltung der Erfindung ist allerdings die den Innenraum begrenzende Wandung mit einem flexiblen, nicht eigensteifen Wandungsmaterial gebildet. Das flexible, nicht eigensteife Wandungsmaterial ermöglicht die Änderung von der ersten Betriebsstellung der Wandung zu der zweiten Betriebsstellung der Wandung.In a further embodiment of the invention, however, the wall bounding the interior is formed with a flexible, not inherently rigid wall material. The flexible, non-rigid wall material allows the change from the first operating position of the wall to the second operating position of the wall.
Weiterhin ist für diese Ausgestaltung eine Haltevorrichtung vorgesehen. Die Haltevorrichtung hält die Wandung in der ersten Betriebsstellung. Dies kann auf beliebige Weise erfolgen. Um hier lediglich einige Beispiele zu nennen kann der Container über eine Art Traggerüst oder ein äußeres Gehäuse verfügen, mittels dessen die flexible, nicht eigensteife Wandung in der ersten Betriebsstellung gehalten ist. Das Wandungsmaterial kann an diesem Traggerüst angeklebt, angeheftet oder anderweitig gehalten sein. Des Weiteren kann das Wandungsmaterial mit Haltevorrichtungen in Form von Spanneinrichtungen oder Entfaltungseinrichtungen, insbesondere in der Art von Zeltstangen, in der ersten Betriebsstellung gehalten werden.Furthermore, a holding device is provided for this embodiment. The holding device holds the wall in the first operating position. This can be done in any way. To mention just a few examples hereof, the container may have a kind of support frame or an outer housing, by means of which the flexible, non-rigid wall is held in the first operating position. The wall material can be glued to this support framework, attached or otherwise held. Furthermore, the wall material can be held in the first operating position with holding devices in the form of tensioning devices or deployment devices, in particular in the manner of tent poles.
Über das Betriebsstellungsänderungsorgan kann dann im Fall eines Feuers die Haltewirkung der Haltevorrichtung aufgehoben oder zumindest verringert werden. Hiermit ist ermöglicht, dass die flexible, nicht eigensteife Wandung die zweite Betriebsstellung einnimmt.In the event of a fire, the holding action of the holding device can then be canceled or at least reduced via the operating position changing element. This makes it possible that the flexible, non-rigid wall takes the second operating position.
Für die Aufhebung oder Verringerung der Haltewirkung der Haltevorrichtung gibt es ebenfalls vielfältige Möglichkeiten. Lediglich beispielhaft wird hier genannt, dass die Wirkung der Haltevorrichtung über einen das Feuer detektierenden Sensor mit zugeordnetem Aktuator aufgehoben oder verringert wird. Für eine einfache Ausführungsform kann die Haltevorrichtung durch sich entwickelnden Rauch oder die Wärme ihre Haltewirkung verlieren, insbesondere indem der Rauch oder die Wärme eine Klebewirkung verringert oder beseitigt oder die Spanneinrichtung oder Entfaltungseinrichtung durch die Wärme oder den Rauch geschwächt wird.For the cancellation or reduction of the holding effect of the holding device, there are also many possibilities. For example only, it is mentioned here that the effect of the holding device is canceled or reduced via a sensor detecting the fire with an associated actuator. For a simple embodiment, the holding device may lose its retaining action by developing smoke or heat, in particular by the smoke or heat reducing or eliminating a sticking action or weakening the tensioning or unfolding device by the heat or smoke.
Die Energie zur Herbeiführung der Änderung der Betriebsstellung von der ersten Betriebsstellung in die zweite Betriebsstellung kann mittels einer beliebigen Energiequelle und einem beliebigen Freigabemechanismus oder Aktuator bereitgestellt werden. Gemäß einer besonderen Ausgestaltungsform der Erfindung ist aber das Betriebsstellungsänderungsorgan mit einem elastischen Verformungselement ausgebildet, welches die Energie zur Änderung der Betriebsstellung zumindest teilweise bereitstellt. Die elastische Vorspannung des Verformungselements ist größer, wenn sich die Wandung in der ersten Betriebsstellung befindet, als wenn sich die Wandung in der zweiten Betriebsstellung befindet. Über eine Entspannung des elastischen Verformungselements wird die Wandung von der ersten Betriebsstellung in die zweite Betriebsstellung überführt, womit das elastische Verformungselement auch (zumindest teilweise) für das Ausschieben des in den Innenraum angeordneten Fluids durch das Rückschlagventilelement nach außen zuständig ist. Bei dem elastischen Verformungselement kann es sich um ein beliebiges diskretes oder kontinuierliches Verformungselement, beispielsweise ein Federelement handeln. Dies kann ständig wirksam sein, wobei die Entspannung des elastischen Verformungselements in der ersten Betriebsstellung durch die Haltevorrichtung unterbunden sein kann und ermöglicht wird, wenn die Haltewirkung der Haltevorrichtung aufgehoben oder verringert wird. In besonderer Ausgestaltung der Erfindung kann aber die Vorspannung des elastischen Verformungselements erst zur Wirkung kommen, wenn sich ein Feuer entwickelt hat. Um ein Beispiels für eine derartige Ausgestaltungsform zu nennen, kann ein thermoplastisches Verformungselement Einsatz finden, in welchem Spannungen eingefroren sind, die mit Überschreiten eines Schwellenwerts einer Temperatur in dem Innenraum des Containers freigesetzt werden.The energy for effecting the change in operating position from the first operating position to the second operating position may be provided by any power source and any release mechanism or actuator. According to a particular embodiment of the invention, however, the operating position change member is formed with an elastic deformation element, which at least partially provides the energy for changing the operating position. The elastic bias of the deformation element is greater when the wall is in the first operating position, as if the wall is in the second operating position. About a relaxation of the elastic deformation element, the wall is transferred from the first operating position to the second operating position, whereby the elastic deformation element is also responsible (at least partially) for pushing out the fluid disposed in the interior through the check valve element to the outside. The elastic deformation element may be any discrete or continuous deformation element, for example a spring element. This can be constantly effective, wherein the relaxation of the elastic deformation element in the first operating position can be prevented by the holding device and is made possible when the holding action of the holding device is canceled or reduced. In a particular embodiment of the invention, however, the bias of the elastic deformation element only come into effect when a Fire has developed. To give an example of such an embodiment, a thermoplastic deformation element can be used, in which stresses are frozen, which are released when a threshold value of a temperature in the interior of the container is exceeded.
Alternativ oder kumulativ kann die Überführung der Wandung von der ersten Betriebsstellung in die zweite Betriebsstellung herbeigeführt werden zumindest teilweise über das Eigengewicht des Wandungsmaterials, wodurch dann auch das Ausschieben des Fluids durch das Rückschlagventilelement verursacht wird. Beispielsweise kann die flexible Wandung in der ersten Betriebsstellung über einem Boden des Containers und den Gütern in dem Container auf Abstand gehalten sein. Zur Herbeiführung der zweiten Betriebsstellung sinkt das flexible Wandungsmaterial von oben auf die Bodenplatte des Containers und die Güter, was auch vergleichbar sein kann mit dem Auflegen einer Löschdecke von oben. Das Eigengewicht des Wandungsmaterials führt dazu, dass sich das Wandungsmaterial eng an die brennenden Güter einlegt und wenig oder kein Oxidationsmittel zwischen Wandungsmaterial und den Gütern verbleibt, da dieses mit dem Absinken des Wandungsmaterials aus dem Innenraum des Containers durch das Rückschlagventilelement abgeführt wird. Es versteht sich, dass für das zuvor erläuterte Absinken des Wandungsmaterials auch Zusatzgewichte Einsatz finden können.Alternatively or cumulatively, the transfer of the wall from the first operating position into the second operating position can be brought about, at least in part, via the dead weight of the wall material, which then also causes the expulsion of the fluid through the check valve element. For example, in the first operating position, the flexible wall may be kept at a distance above a bottom of the container and the goods in the container. To bring about the second operating position, the flexible wall material drops from above onto the bottom plate of the container and the goods, which can also be comparable to the laying of a fire blanket from above. The weight of the wall material causes the wall material fits tightly to the burning goods and little or no oxidant between wall material and the goods remains because it is removed with the sinking of the wall material from the interior of the container through the check valve element. It is understood that additional weights can also be used for the above-described lowering of the wall material.
Grundsätzlich ist der Gehäuse-, Wand- und Bodenaufbau für den erfindungsgemäßen Container beliebig. Beispielsweise kann als Bodenplatte eine feuerresistente Palette Einsatz finden, wie diese in
Von Vorteil ist, wenn für das Wandungsmaterial ein nicht oder ein nur schwer entflammbares Material eingesetzt wird. In der Praxis hat sich ein flexibles, nicht eigensteifes Wandungsmaterial als besonders tauglich herausgestellt, welches mit einem schwer entflammbaren Textil- oder Polymermaterial gebildet ist.It is advantageous if a non-flammable or a flame-retardant material is used for the wall material. In practice, a flexible, not intrinsically rigid wall material has proven to be particularly suitable, which is formed with a flame retardant textile or polymer material.
Möglich ist, dass der Container mit den zuvor erläuterten Merkmalen gefertigt und vertrieben wird. Gemäß einem weiteren Vorschlag der Erfindung wird ein Nachrüstsatz vorgeschlagen, für welchen ein herkömmlicher Container zu einem Container nach einem der vorhergehenden Ansprüche umrüstbar ist. Dieser Nachrüstsatz besitzt dann eine Wandung aus einem flexiblen und nicht eigensteifen Wandungsmaterial, welche zur Begrenzung eines Innenraums in den herkömmlichen Behälter einbringbar ist. Weiterhin verfügt der Nachrüstsatz über ein Rückschlagventilelement der zuvor erläuterten Art, über welches Fluid von dem durch die flexible Wandung begrenzten Innenraum nach außen, also in den herkömmlichen Container und/oder in die Umgebung abführbar ist. Weiterhin ist der Nachrüstsatz mit einem Betriebsstellungsänderungsorgan der zuvor erläuterten Art ausgestattet.It is possible that the container is manufactured and sold with the features explained above. According to a further proposal of the invention, a retrofit kit is proposed for which a conventional container can be converted into a container according to one of the preceding claims. This retrofit kit then has a wall of a flexible and non-rigid wall material, which can be introduced to limit an interior in the conventional container. Furthermore, the retrofit kit has a check valve element of the type described above, via which fluid can be discharged from the space bounded by the flexible wall to the outside, ie in the conventional container and / or in the environment. Furthermore, the retrofit kit is equipped with a Betriebsstellungsänderungsorgan of the type described above.

Der Innenraum 7 hat in der ersten Betriebsstellung ein Volumen Vl1, während die Güter 8 ein Volumen VG besitzen. Zwischen der Zeltplane 4, der Bodenplatte 2 und den Gütern 8 verbleibt ein freies Volumen, welches mit einem Fluid, vorzugsweise Luft, mit einem Fluidvolumen VF1 gefüllt ist. Zwischen Innenraum 7 und der Umgebung 9 sind Rückschlagventilelemente 10a, 10b angeordnet, die für das dargestellte Ausführungsbeispiel in die Zeltplane 4 integriert sind. Ebenfalls möglich ist, dass Rückschlagventilelemente 10 in die Bodenplatte 2 integriert sind. Die Rückschlagventilelemente 10 sperren eine Strömung von Luft aus der Umgebung 9 in den Innenraum 7, während die Rückschlagventilelemente 10 die Strömung von Luft aus dem Innenraum 7 in die Umgebung 9 ermöglichen.The
Erfindungsgemäß tritt mit der Herbeiführung der zweiten Betriebsstellung eine Verminderung des Oxidationsmittels in dem Innenraum 7 ein, die korreliert mit dem Volumen des abgeführten Fludis VD, womit die Ausbildung eines Feuers gehemmt wird und ein Feuer ersticken kann.According to the invention occurs with the induction of the second operating position, a reduction of the oxidizing agent in the
Für die Verformungselemente 5 kommen insbesondere bei der Herstellung gestreckte und in gestrecktem Zustand abgekühlte Thermoplaste zum Einsatz, die die Eigenschaften besitzen, sich unter Wärmeeinwirkung in ihren ungestreckten Ausgangszustand zurück zu orientieren. Dabei sind Schrumpfverhältnisse von mehr als 3:1, 5:1, 8:1 oder 10:1 realisierbar. Je nach Materialkonfiguration kann der Schwellwert der die Schrumpfung auslösende Temperatur zwischen 65° und 125°, beispielsweise zwischen 80° und 110° oder oberhalb von 90°, liegen, in Einzelfällen jedoch auch darüber oder darunter.For the deformation elements 5 are used in particular in the production stretched and cooled in the stretched state thermoplastics are used, which have the properties to orient themselves under heat in their unstretched initial state back. In this case, shrinkage ratios of more than 3: 1, 5: 1, 8: 1 or 10: 1 can be realized. Depending on the material configuration, the threshold value of the temperature causing the shrinkage may be between 65 ° and 125 °, for example between 80 ° and 110 ° or above 90 °, but in some cases also above or below it.

Vorzugsweise ist das mit den Zeltstangen 3 gebildete Stützgestänge aus einem Thermoplast hergestellt, der wie zuvor beschrieben gestreckt worden ist mit eingefrorenen Dehnungen. Die Herstellung eines derartigen Stützgestänges kann vergleichsweise einfach durch Extrusion erfolgen, was auch dem Herstellungsprozess für gestreckte Thermoplaste entspricht. Für die Zeltplane 4 oder anderweitige Wandung 14 findet insbesondere ein textiles oder polymeres Material Einsatz, in das, wie in
Sofern in dem Container 1 ein Feuer ausbricht, setzt bei Überschreiten des Schwellenwerts der Schrumpfungstemperatur des Thermoplasts ohne zusätzliches manuelles Eingreifen automatisch die Rückorientierung des Thermoplasts im Stützgestänge, insbesondere der Zeltstangen 3 und der Verformungselemente 5, ein. Dadurch wird die Wandung 14 gerafft und es kommt zu einer Reduzierung des Volumens im Innenraum 7. Bei der Wahl des Thermoplasts ist darauf zu achten, dass es sich um ein möglichst widerstandsfähiges und temperaturbeständiges Material handelt. Der Schwellenwert der Schrumpfungstemperatur des eingesetzten Thermoplasts ist derart zu wählen, dass dieser geringfügig oberhalb der maximal im Betrieb des Containers 1 erwarteten Temperatur liegt.If a fire breaks out in the
Der erfindungsgemäße Container 1 kann wartungsfrei ausgebildet sein. Eine Schädigung einer Wandung 14 hat aufgrund der Vielzahl der möglichen Verformungselemente 5 oder Thermoplastbänder unter Umständen nur einen geringen Einfluss auf die feuerlöschende Funktion.The
