Description

Die vorliegende Erfindung betrifft einen Faltkörper mit einem Grundbogen, wobei der Grundbogen zumindest in einem Körperzustand faltbar ist, in dem ein Teil des Grundbogens eine Lasteintragsfläche ausbildet und ein anderer Teil des Grundbogens eine lastübertragende Struktur ausbildet, sodass im Körperzustand des Faltkörpers eine externe Last aufgenommen und abgeleitet werden kann.The present invention relates to a folding body with a base sheet, the base sheet being foldable at least in a body state in which part of the base sheet forms a load application area and another part of the base sheet forms a load-transferring structure, so that in the body state of the folding body an external load is absorbed and can be derived.

Derartige Faltkörper können beispielsweise als faltbare Möbel, insbesondere als faltbare Sitzgelegenheiten, faltbare Tische oder dergleichen dienen. Gleichermaßen können derartige Faltkörper jedoch auch zu anderen Zwecken angewendet werden. Die gattungsgemäßen Faltkörper weisen je nach Ausgestaltung verschiedene Nachteile auf. Beispielsweise sind Faltkörper bekannt, deren Grundbogen eine komplexe, ggf. mehrteilige Struktur aufweisen und bei denen sowohl die Herstellung des Körperzustands als auch eine umgekehrte Rücküberführung des Faltkörpers aus dem Körperzustand in einen anderen Zustand komplex oder schwierig ausfällt.Such folding bodies can serve, for example, as foldable furniture, in particular as foldable seating, foldable tables or the like. Likewise, however, such folding bodies can also be used for other purposes. The generic folding bodies have various disadvantages, depending on their configuration.

An derartigen Faltkörpern ist nachteilig, dass die Faltkörper wenig portabel sind, da sowohl im Körperzustand des Grundbogens als auch im Flachzustands des Grundbogens ein erheblicher Platzbedarf besteht.Likewise, folding bodies are known whose base sheet can only be transferred between the said body state and a flat state, the flat state generally relating to a state in which the base sheet is distributed or sold and in which the base sheet assumes an essentially flat or flat shape which can then be converted into the body state of the folded body by deforming fold areas formed in the base sheet. A disadvantage of such folding bodies is that the folding bodies are not very portable, since a considerable amount of space is required both in the body state of the base sheet and in the flat state of the base sheet.

Ausgehend von dem vorgenannten Stand der Technik liegt der Erfindung daher die Aufgabe zugrunde, einen Faltkörper vorzuschlagen, der die Nachteile im Stand der Technik überwindet, insbesondere liegt die Aufgabe darin, einen Faltkörper vorzusehen, der besonders leicht und praktisch transportiert oder von einem Benutzer mitgeführt werden kann und gleichzeitig eine besonders einfache Struktur des Grundbogens ermöglicht.the AT 14 341 U1 also shows a folding body which can be folded from a base sheet into a body state by means of an adhesive point on a load-transferring structure. The base arch has a jacket section with four laterally adjoining ear sections, the ear sections also forming the load application area. Based on the aforementioned prior art, the invention is therefore based on the object of proposing a folding body which overcomes the disadvantages in the prior art, in particular the object is to provide a folding body that is particularly easy and practical to transport or to be carried by a user can and at the same time enables a particularly simple structure of the base arch.

Diese Aufgabe wird durch einen Faltkörper gemäß Anspruch 1 gelöst, der einen flachen, zusammenhängenden, insbesondere einstückigen Grundbogen aufweist, welcher statische Bereiche und zwischen den statischen Bereichen ausgebildete Faltenbereiche aufweist, wobei die Faltenbereiche und die statischen Bereiche so angeordnet sind, dass der Grundbogen durch Verformungen der Faltbereiche in zumindest einen Flachzustand, einen Packzustand und einen Körperzustand faltbar ist, wobei der Faltkörper im Körperzustand des Grundbogens eine Lasteintragsfläche aufweist, die durch zumindest einen der statischen Bereiche ausgebildet ist und, ebenfalls im Körperzustand des Grundbogens, unterhalb der Lasteintragsfläche eine lastübertragende Struktur angeordnet oder ausgebildet ist, die durch eine Mehrzahl von statischen Bereichen ausgebildet ist, wobei die statischen Bereiche der lastübertragenden Struktur senkrecht zu dem zumindest einen statischen Bereich der Lasteintragsfläche ausgerichtet sind und die statischen Bereiche der lastübertragenden Struktur senkrecht zur Lasteintragsfläche eine Kreuzform ausbilden, wobei der Faltkörper im Flachzustand des Grundbogens einen rechteckigen Mantelabschnitt und vier Ohrenabschnitte aufweist, von denen jeweils zwei an einer langen Seite des Mantelabschnitts des Grundbogens angeordnet sind.This object is achieved by a folding body according to claim 1, which has a flat, coherent, in particular one-piece base sheet which has static areas and fold areas formed between the static areas, the fold areas and the static areas being arranged in such a way that the base sheet is deformed the folding area can be folded into at least one flat state, one packed state and one body state, with the folded body in the body state of the base sheet having a load application area which is formed by at least one of the static areas and, also in the body state of the base sheet, a load-transferring structure is arranged below the load application area or is formed, which is formed by a plurality of static areas, wherein the static areas of the load-transmitting structure are aligned perpendicular to the at least one static area of the load application surface and the Static areas of the load-transferring structure perpendicular to the load-bearing surface form a cross shape, with the folded body in the flat state of the base sheet having a rectangular jacket section and four ear sections, two of which are arranged on a long side of the jacket section of the base sheet.

Durch den erfindungsgemäßen Faltkörper wird einerseits erreicht, dass der Faltkörper und dessen zusammenhängender Grundbogen neben dem Körperzustand und dem Flachzustand auch in einen Packzustand überführt werden kann. Dies wiederum erlaubt in besonders vorteilhafter Weise, dass der Faltkörper einfach und komfortabel von einem Benutzer mitgeführt und an dem jeweils gewünschten Ort einfach und schnell in den Körperzustand überführt und zur Aufnahme und Ableitung einer Last benutzt werden kann. Darüber hinaus ermöglicht der Faltkörper durch die besonders einfache Ausgestaltung des Grundbogens ein einfaches und schnelles Herstellen sowie Wechseln zwischen den jeweiligen Zuständen des Grundbogens. Außerdem wird durch die einfache Form des Grundbogens eine entsprechend einfache und kostengünstige Herstellung des Faltkörpers ermöglicht.The folding body according to the invention achieves on the one hand that the folding body and its coherent base curve can be converted into a pack state in addition to the body state and the flat state. This in turn allows in a particularly advantageous manner that the folding body can be carried along easily and comfortably by a user and can be easily and quickly converted into the body state at the respectively desired location and used for receiving and discharging a load. In addition, thanks to the particularly simple design of the base sheet, the folding body enables simple and quick production and changing between the respective states of the base sheet. In addition, the simple shape of the base sheet enables a correspondingly simple and inexpensive production of the folding body.

Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous further developments of the invention are specified in the subclaims.

Als Grundbogen für den Faltkörper kommen grundsätzlich unterschiedlichste Werkstoffe in Frage, die sich für die Ausbildung eines entsprechend flachen Grundbogens eignen. Beispielsweise kann Pappe, insbesondere Wellpappe, Holz, beispielsweise Balsaholz, Faserverbundwerkstoffe, beispielsweise Karbon, Kunststoffe, beispielsweise PET-Schäume sowie weitere Materialien und Kombinationen der vorgenannten Materialien zum Einsatz kommen. Die vorangehend genannten Materialien bilden dabei bevorzugt die statischen Bereiche des Grundbogens aus. Für die Faltbereiche des Grundbogens kann sowohl dasselbe Material wie für die statischen Bereiche des Grundbogens verwendet werden. Dies kann beispielsweise bei einer Ausgestaltung der statischen Bereiche des Grundbogens in Form von Pappe, insbesondere Wellpappe der Fall sein. In einer solchen Ausgestaltungsform kann die Ausbildung der Faltbereiche im Grundbogen durch das Vorsehen oder Erzeugen entsprechender Falzlinien oder Falzbrüche erreicht werden.A wide variety of materials, which are suitable for the formation of a correspondingly flat base curve, are fundamentally possible as the base curve for the folding body. For example, cardboard, in particular corrugated cardboard, wood, for example balsa wood, fiber composite materials, for example carbon, plastics, for example PET foams, and other materials and combinations of the aforementioned materials can be used. The aforementioned materials preferably form the static areas of the base arch. The same material as for the static areas of the Base sheet can be used. This can be the case, for example, when the static areas of the base sheet are configured in the form of cardboard, in particular corrugated cardboard. In such an embodiment, the formation of the fold areas in the base sheet can be achieved by providing or generating corresponding fold lines or fold breaks.

Bei Pappe und anderen Materialien des Grundbogens, insbesondere der statischen Bereiche des Grundbogens, kann vorgesehen sein, dass die Faltbereiche durch ein Material ausgebildet werden, welche sich vom Material der statischen Bereiche unterscheidet. Beispielsweise kann für eine Ausführungsform, in der die statischen Bereiche des Grundbogens durch einen Faserverbundwerkstoff, beispielsweise Karbon, gebildet werden, die Faltbereiche durch sogenannte Folienwinkel oder Foliengelenke ausgebildet werden, welche mit den statischen Bereichen des Grundbogens zu einem zusammenhängenden, flachen Grundbogen verbunden sind. Beispielsweise kann vorgesehen sein, dass die statischen Bereiche des Grundbogens insgesamt mit einer Folie, beispielsweise einer Kunststofffolie überdeckt und mit der Folie verbunden sind, sodass ein jeweiliger Abstand zwischen den statischen Bereichen des Grundbogens zur Ausbildung eines Faltbereichs führt, der dann von dem entsprechenden Folienabschnitt gebildet wird, welcher sich über den Abstand der statischen Bereiche erstreckt und als Folienwinkel oder Foliengelenk wirkt.In the case of cardboard and other materials of the base sheet, in particular the static areas of the base sheet, it can be provided that the fold areas are formed by a material which differs from the material of the static areas. For example, for an embodiment in which the static areas of the base sheet are formed by a fiber composite material, for example carbon, the fold areas can be formed by so-called foil angles or foil joints, which are connected to the static areas of the base sheet to form a coherent, flat base sheet. For example, it can be provided that the static areas of the base sheet are entirely covered with a film, for example a plastic sheet, and connected to the sheet so that a respective distance between the static areas of the base sheet leads to the formation of a fold area, which is then formed by the corresponding sheet section which extends over the distance between the static areas and acts as a foil angle or foil joint.

Besonders vorteilhaft an der erfindungsgemäßen Ausgestaltung des Faltkörpers ist auch die Ausgestaltung der Lasteintragsfläche und der lastübertragenden Struktur im Körperzustand des Grundbogens. Die senkrecht zur Lasteintragsfläche eine Kreuzform ausbildende lastübertragende Struktur führt dazu, dass eine auf der Lasteintragsfläche angeordnet Last gleichmäßig und sicher aufgenommen und abgeleitet werden kann, ohne dass für den Faltkörper, insbesondere den Grundbogen merkliche Verformungen oder Abnutzungen bedingt werden, selbst bei Lasteinträgen von 100 kg und mehr.The configuration of the load application surface and the load-transferring structure in the body state of the base curve is also particularly advantageous in the configuration of the folding body according to the invention. The load-transferring structure, which forms a cross shape perpendicular to the load-bearing surface, means that a load arranged on the load-bearing surface is evenly and safely absorbed and dissipated without causing noticeable deformations or wear on the folding body, in particular the base arch, even with loads of 100 kg and more.

Besonders bevorzugt sind die Ohrenabschnitte des Grundbogens im Flachzustand paarweise sich gegenüberliegend an den zwei langen Seiten des Mantelabschnitts des Grundbogens angeordnet. Dadurch wird eine gleichermaßen einfache und symmetrische Form des Grundbogens erreicht. Dies führt wiederum dazu, dass die Überführung des Grundbogens zwischen dem Flachzustand, dem Packzustand und dem Körperzustand besonders einfach und intuitiv gestaltet wird. Außerdem kann der Grundbogen besonders material- oder platzsparend und damit besonders günstig hergestellt werden.In the flat state, the ear sections of the base curve are particularly preferably arranged opposite one another in pairs on the two long sides of the jacket section of the base curve. This results in an equally simple and symmetrical shape of the base arch. This in turn means that the transition of the base sheet between the flat state, the packed state and the body state is designed to be particularly simple and intuitive. In addition, the base arch can be produced in a particularly material or space-saving manner and thus particularly inexpensively.

Eine weitere besonders bevorzugte Ausgestaltung des Faltkörpers sieht vor, dass die Lasteintragsfläche im Körperzustand des Grundbogens zumindest zwei parallel zueinander angeordnete statische Bereiche aufweist. Besonders bevorzugt sind die zwei statischen Bereiche unmittelbar aufeinander aufliegend angeordnet, sodass die Lasteintragsfläche im Körperzustand des Grundbogens eine zumindest doppelt so große Stärke aufweist, wie der Grundbogen im Flachzustand. Mit anderen Worten ausgedrückt bedeutet dies, dass die Lasteintragsfläche im Körperzustand des Grundbogens zumindest die Stärke von zwei statischen Bereichen des Grundbogens aufweist. Dadurch wird in besonders vorteilhafter Weise ermöglicht, dass die Lasteintragsfläche eine hohe Stabilität und einen hohen Widerstand gegen Verformungen aufweist und somit ohne Gefahr der Ermüdung oder des Verschleißes auch hohe Lasten aufnehmen kann.Another particularly preferred embodiment of the folding body provides that the load application surface has at least two static areas arranged parallel to one another in the body state of the base arch. The two static areas are particularly preferably arranged directly on top of one another, so that the load application area in the body state of the base curve is at least twice as thick as the base curve in the flat state. In other words, this means that the load application area in the body state of the base curve has at least the thickness of two static areas of the base curve. This makes it possible in a particularly advantageous manner that the load application surface has a high level of stability and a high resistance to deformation and can thus also absorb high loads without the risk of fatigue or wear.

Besonders zweckmäßig ist darüber hinaus eine Ausführungsvariante des Faltkörpers, bei dem der Grundbogen Laschen und Ausnehmungen aufweist, die paarweise miteinander in Eingriff bringbar sind, um zumindest im Körperzustand des Grundbogens die Position und/oder Ausrichtung der statischen Bereiche zueinander zu fixieren. Dies ermöglicht in besonders wünschenswerter Weise, dass ohne weitere Mittel oder Vorrichtungen der Körperzustand des Grundbogens des Faltkörpers aufrechterhalten wird, insbesondere auch dann, wenn kein Lasteintrag auf die Lasteintragsfläche erfolgt. Besonders vorteilhaft kann vorgesehen sein, dass der Eingriff zwischen den Laschen und den Ausnehmungen des Grundbogens auch entsprechend reversibel wieder lösbar ist, um eine Überführung des Grundbogens aus dem Körperzustand in den Flachzustand und/oder in den Packzustand überführen zu können. Für die Laschen kann dasselbe Material zum Einsatz kommen, wie für die statischen Bereiche des Grundbogens. Die Laschen können dabei ebenfalls durch entsprechende Faltbereiche mit den statischen Bereichen des Grundbogens verbunden sein. Alternativ können die Laschen auch einstückig an statischen Bereichen des Grundbogens angeformt oder ausgebildet sein. Die Ausnehmungen sind bevorzugt als sich über die gesamte Stärke des Grundbogens erstreckende Löcher, insbesondere Langlöcher ausgebildet. In dieser Ausgestaltung können die Ausnehmungen besonders einfach hergestellt werden. Alternativ können die Ausnehmungen jedoch auch als sich nur teilweise über die Stärke des Grundbogens oder statischen Bereiche erstreckende Vertiefungen, insbesondere Nuten ausgebildet sein.In addition, a variant of the folding body in which the base sheet has tabs and recesses is particularly useful which can be brought into engagement with one another in pairs in order to fix the position and / or alignment of the static areas to one another at least in the body state of the base arch. This makes it possible in a particularly desirable way that the physical state of the base curve of the folded body is maintained without further means or devices, in particular also when there is no load application on the load application area. It can particularly advantageously be provided that the engagement between the tabs and the recesses of the base sheet can also be reversibly released again in order to be able to convert the base sheet from the body state to the flat state and / or into the packed state. The same material can be used for the flaps as for the static areas of the base arch. The flaps can also be connected to the static areas of the base sheet by corresponding folding areas. Alternatively, the tabs can also be formed or formed in one piece on static areas of the base arch. The recesses are preferably designed as holes, in particular elongated holes, extending over the entire thickness of the base arch. In this embodiment, the recesses can be produced in a particularly simple manner. Alternatively, however, the recesses can also be designed as depressions, in particular grooves, which only partially extend over the thickness of the base arch or static areas.

Gemäß einer besonders bevorzugten Ausgestaltung der Mantelfläche kann vorgesehen sein, dass diese fünf statische Bereiche umfasst, zwischen denen vier parallel zueinander, insbesondere parallel zu einer kurzen Seite des Mantelabschnitts, verlaufende Faltbereiche angeordnet sind. Damit wird ein einfaches und intuitives Falten des Faltkörpers, insbesondere ein einfaches und intuitives Überführen des Grundbogens des Faltkörpers in die jeweiligen Zustände ermöglicht.According to a particularly preferred embodiment of the jacket surface, it can be provided that it comprises five static areas, between which four fold areas are arranged that run parallel to one another, in particular parallel to a short side of the jacket section. This enables a simple and intuitive folding of the folding body, in particular a simple and intuitive transfer of the base sheet of the folding body into the respective states.

Erfindungsgemäß bilden zwei äußere statische Bereiche des Mantelabschnitts des Grundbogens im Körperzustand des Grundbogens die Lasteintragsfläche aus. Dadurch wird einerseits die oben bereits angedeutete besonders vorteilhafte Ausgestaltung ermöglicht, in der die Lasteintragsfläche durch zumindest zwei parallel zueinander angeordnete statische Bereiche ausgebildet wird. Außerdem wird besonders vorteilhaft erreicht, dass die jeweils an die äußeren statischen Bereiche, welche die Lasteintragsfläche ausbilden, angrenzenden statischen Bereiche zusätzlich zu den Ohrenabschnitten des Grundbogens weitere Bestandteile der lastübertragenden Struktur im Körperzustand des Grundbogens ausbilden und damit eine noch bessere und sicherere Lastübertragung von auf der Lasteintragsfläche angeordneten Lasten gewährleisten.According to the invention, two outer static areas of the jacket section of the base curve form the load application area in the body state of the base curve. As a result, on the one hand, the particularly advantageous embodiment already indicated above is made possible, in which the load application area is formed by at least two static areas arranged parallel to one another. In addition, it is particularly advantageously achieved that the static areas adjoining the outer static areas that form the load application area, in addition to the ear sections of the base curve, form further components of the load-transferring structure in the body state of the base curve and thus an even better and safer load transfer from the base curve Ensure loads arranged in the load application area.

Eine weitere besonders vorteilhafte Ausgestaltung des Faltkörpers sieht vor, dass die Ohrenabschnitte des Grundbogens als statische Bereiche ausgeführt sind und zwischen den Ohrenabschnitten und dem Mantelabschnitt des Grundbogens Faltbereiche angeordnet sind. Die besagten Faltbereiche erstrecken sich insbesondere parallel zur langen Seite des Mantelabschnitts. Dadurch kann besonders vorteilhaft erreicht werden, dass der Grundbogen einfach und günstig herstellt werden kann.Another particularly advantageous embodiment of the folding body provides that the ear sections of the base curve are designed as static areas and folding areas are arranged between the ear sections and the jacket section of the base curve. Said fold areas extend in particular parallel to the long side of the jacket section. As a result, it can be achieved in a particularly advantageous manner that the base curve can be produced simply and inexpensively.

Außerdem kann in einer weiteren Ausgestaltung des Faltkörpers besonders vorteilhaft vorgesehen sein, dass die Ohrenabschnitte des Grundbogens im Körperzustand des Grundbogens zumindest teilweise die lastübertragende Struktur, insbesondere die Kreuzform der lastübertragenden Struktur, ausbilden. Diese Ausgestaltung hat ebenfalls den Vorteil, dass eine sehr leichte und intuitive Überführung des Grundbogens zwischen Flachzustand, Packzustand und Körperzustand erreicht wird.In addition, in a further embodiment of the folding body, it can be particularly advantageously provided that the ear portions of the base curve in the body state of the base curve at least partially form the load-transferring structure, in particular the cross-shape of the load-transferring structure. This configuration also has the advantage that a very easy and intuitive transition of the base sheet between flat, packed and body conditions is achieved.

Gemäß einer weiteren besonders bevorzugten Ausgestaltung kann vorgesehen sein, dass die statischen Bereiche des Mantelabschnitts im Körperzustand des Grundbogens einen Quader, insbesondere einen Würfel mit zwei einander gegenüberliegenden, offenen Seiten ausbilden. Dadurch werden verschiedene Vorteile erreicht. Einerseits führt auch diese Ausgestaltung zu einer einfachen Herstellung und Wiederauflösung der jeweiligen Zustände des Grundbogens des Faltkörpers. Darüber hinaus wird über die Ausbildung eines zweiseitig offenen Quaders oder Würfels die Stabilität des Faltkörpers im Körperzustand des Grundbogens weiter verbessert. Ebenfalls ermöglicht die zweiseitig insbesondere einander gegenüberliegend offene Ausgestaltung des Quaders oder Würfels, dass im Körperzustand des Grundbogens die korrekte und intakte Anordnung und Fixierung der Kreuzform der lastübertragenden Struktur optisch identifiziert und sichergestellt wird.According to a further particularly preferred embodiment, it can be provided that the static areas of the casing section form a cuboid, in particular a cube, with two opposite, open sides in the body state of the base arch. This achieves various advantages. On the one hand, this configuration also leads to a simple production and re-dissolution of the respective states of the base sheet of the folded body. In addition, the stability of the folded body in the body state of the base sheet is further improved by the formation of a cuboid or cube that is open on both sides. The design of the parallelepiped or cube, which is open on both sides, in particular opposite one another, also enables the correct and intact arrangement and fixation of the cross shape of the load-transferring structure to be optically identified and ensured in the physical state of the base arch.

In einer besonders bevorzugten Ausgestaltung des Faltkörpers kann vorgesehen sein, dass im Packzustand des Grundbogens eine Höhe des Faltkörpers das acht- bis zwölffache, bevorzugt das neun- bis elffache, besonders bevorzugt das zehnfache der Stärke des Grundbogens beträgt. Im Packzustand des Grundbogens ist dementsprechend besonders bevorzugt vorgesehen, dass die statischen Bereiche des Grundbogens alle insgesamt weitestgehend parallel zueinander und aneinander angrenzend oder aufeinander aufliegend angeordnet sind, so dass insgesamt eine Höhe des Grundbogens erreicht wird, die nur ein achtfaches bis zwölffaches der Stärke des Grundbogens beträgt. Dies hat besonders vorteilhaft zur Folge, dass der Faltkörper im Packzustand eine sehr kompakte Form einnimmt, was wiederum die Voraussetzung dafür ist, dass der Faltkörper im Packzustand leicht und sicher transportiert oder mitgeführt werden kann. Durch eine Höhe des Grundbogens im Packzustand, wie vorangehend genannt, wird beispielsweise erreicht, dass der Faltkörper im Packzustand ohne weiteres in einer Tasche, beispielsweise in einer Handtasche, Aktentasche od.dgl. verstaut und mitgeführt werden kann. Um sicherzugehen, dass der Grundbogen im Packzustand verbleibt können einerseits Laschen und Ausnehmungen zum Einsatz kommen, wie sie oben bereits zur Fixierung des Körperzustands des Grundbogens beschrieben wurden. Alternativ oder zusätzlich hierzu kann jedoch auch vorgesehen sein, dass der Faltkörper im Packzustand einen Beutel oder eine Hülle umfasst, welcher an die Dimension des Grundbogens im Packzustand angepasst ist und damit sicherstellt, dass der Grundbogen sich nicht versehentlich oder unbeabsichtigt aus dem Packzustand in einen anderen Zustand oder einen Zwischenzustand verformt oder faltet.In a particularly preferred embodiment of the folding body, it can be provided that in the pack state of the base sheet a height of the folding body is eight to twelve times, preferably nine to eleven times, particularly preferably ten times the thickness of the base sheet. In the pack state of the base sheet, it is particularly preferred that the static areas of the base sheet are all arranged largely parallel to one another and adjacent to one another or lying on top of one another, so that overall a height of the base sheet is achieved that is only eight to twelve times the thickness of the base sheet amounts to. This has the particularly advantageous consequence that the folding body assumes a very compact shape in the packed state, which in turn is the prerequisite for the folding body to be easily and safely transported or carried along in the packed state. A height of the base sheet in the packing state, as mentioned above, is achieved, for example, that the folding body in the packed state easily in a pocket, for example in a handbag, briefcase or the like. can be stowed and carried along. In order to ensure that the base sheet remains in the pack state, on the one hand tabs and recesses can be used, as were already described above for fixing the body condition of the base sheet. Alternatively or in addition to this, however, it can also be provided that the folding body in the packed state comprises a bag or a sleeve which is adapted to the dimensions of the base sheet in the packed state and thus ensures that the base sheet does not accidentally or unintentionally move from the packed state to another State or an intermediate state deformed or folds.

Besonders zweckmäßig kann zudem vorgesehen werden, dass im Packzustand des Grundbogens eine Fläche des Faltkörpers, insbesondere eine senkrecht zur Höhe des Faltkörpers im Packzustand des Grundbogens verlaufende Fläche des Faltkörpers, eine Kantenlänge von 330 mm, insbesondere von 300 mm, besonders bevorzugt von 250 mm, nicht übersteigt. Auch dadurch wird in besonders vorteilhafter Weise erreicht, dass der Faltkörper im Packzustand des Grundbogens ein kompaktes Außenmaß, insbesondere ein kompaktes Volumen einnimmt und somit leicht, einfach und bequem transportiert, insbesondere in einer Tasche, mitgeführt werden kann. Besonders bevorzugt kann vorgesehen sein, dass die Fläche des Faltkörpers im Packzustand des Grundbogens im Wesentlichen rechteckig ausgestaltet ist. Dabei kann beispielsweise vorgesehen sein, dass eine erste Kantenlänge 330 mm, insbesondere 300 mm nicht übersteigt und eine zweite Kantenlänge 250 mm nicht übersteigt. Mit anderen Worten ausgedrückt bedeutet dies, dass im Packzustand des Grundbogens die Fläche des Faltkörpers nur geringfügig kleiner oder geringfügig größer ausfällt, als das Format DIN-A4.It can also be particularly expediently provided that in the packed state of the base sheet a surface of the folded body, in particular a surface of the folded body that runs perpendicular to the height of the folded body in the packed state of the base sheet, has an edge length of 330 mm, in particular 300 mm, particularly preferably 250 mm, does not exceed. This also achieves in a particularly advantageous manner that the folding body has a compact external dimension, in particular a compact volume, in the packed state of the base sheet and can thus be easily, simply and conveniently transported, in particular in a pocket. It can particularly preferably be provided that the surface of the folding body is designed to be essentially rectangular in the pack state of the base sheet. For example, it can be provided that a first edge length does not exceed 330 mm, in particular 300 mm, and a second edge length does not exceed 250 mm. In other words, this means that when the base sheet is packed, the area of the folding body is only slightly smaller or slightly larger than the A4 format.

Ebenfalls kann gemäß einer vorteilhaften Ausgestaltung des Faltkörpers vorgesehen sein, dass im Packzustand des Grundbogens die Faltbereiche des Mantelabschnitts abwechselnd in unterschiedliche Richtungen um 180° gefaltet sind, sodass die statischen Bereiche des Mantelabschnitts im Wesentlichen deckungsgleich übereinander angeordnet sind. Dadurch wird eine ebenfalls besonders kompakte Form und ein besonders kompaktes Volumen des Faltkörpers im Packzustand des Grundbogens erreicht. Um diese Ausgestaltung zu ermöglichen, sind die Faltbereiche des Mantelabschnitts des Grundbogens dementsprechend so auszuführen, dass eine Leporeloo- oder Zickzackfaltung der statischen Bereiche des Mantelabschnitts im Packzustand des Grundbogens erreicht werden kann.According to an advantageous embodiment of the folding body, it can also be provided that, when the base sheet is packed, the folding areas of the casing section are alternately folded in different directions by 180 °, so that the static areas of the casing section are arranged essentially congruently one above the other. As a result, a particularly compact shape and a particularly compact volume of the folding body in the pack state of the base sheet is achieved. In order to make this configuration possible, the folding areas of the casing section of the base sheet are to be designed in such a way that a Leporeloo or zigzag folding of the static areas of the casing section can be achieved when the base sheet is packed.

Eine weitere ebenfalls besonders zweckmäßige Ausführungsvariante des Faltkörpers sieht vor, dass im Packzustand des Grundbogens die Faltbereiche zwischen den Ohrenabschnitten und den statischen Bereichen des Mantelabschnitts eine 180°-Faltung aufweisen und die Ohrenabschnitte sich zumindest abschnittsweise überlappend zwischen zwei, statischen Bereichen des Mantelabschnitts angeordnet sind. Auch diese Ausgestaltung führt zu einem besonders kompakten Packmaß des Faltkörpers im Packzustand des Grundbogens und führt zu einem sicheren Verstauen, insbesondere der Ohrenabschnitte im Packzustand des Grundbogens, für welche bevorzugt keine weiteren Fixierungsmittel, wie beispielsweise Laschen-Ausnehmungen-Kombinationen od.dgl., vonnöten sind.Another particularly useful variant of the folding body provides that when the base sheet is packed, the folding areas between the ear sections and the static areas of the jacket section have a 180 ° fold and the ear sections are arranged at least partially overlapping between two static areas of the jacket section. This configuration also leads to a particularly compact pack size of the folding body in the pack state of the base sheet and leads to a secure stowage, in particular of the ear sections in the pack state of the base sheet, for which preferably no further fixing means, such as flap-recess combinations or the like., Are required are.

Fig. 1 zeigt einen Faltkörper 1 sowie dessen Grundbogen 2. Der Grundbogen 2 umfasst neben einem Mantelabschnitt 3 insgesamt vier Ohrenabschnitte 4. Der Mantelabschnitt 3 weist insgesamt fünf statische Bereiche 5.1, 5.2, 5.3 auf, in welche durch jeweils zwischen den statischen Bereichen 5.1, 5.2, 5.3 vorgesehene Faltbereiche 6 voneinander getrennt sind, welche in der Darstellung der Fig. 1 strichpunktiert dargestellt sind. Die Faltbereiche 6 verlaufen dabei jeweils parallel zur kurzen Seite 7 des rechteckigen Mantelabschnitts 3. An der langen Seite 8 des Mantelabschnitts 3 sind die Ohrenabschnitte 4 jeweils paarweise sich gegenüberliegend an der langen Seite 8 des Mantelabschnitts 3 angeordnet. Auch zwischen den statischen Bereichen 5.2 des Mantelabschnitts 3 und den als statischen Bereichen ausgebildeten Ohrenabschnitten 4 sind Faltbereiche 6 angeordnet, die jeweils parallel zu langen Seite 8 des Mantelabschnitts 3 verlaufen. Fig. 1 shows a folding body 1 and its base sheet 2. The base sheet 2 comprises a jacket section 3, a total of four ear sections 4. The jacket section 3 has a total of five static areas 5.1, 5.2, 5.3, into which between the static areas 5.1, 5.2, 5.3 provided folding areas 6 are separated from each other, which in the illustration of Fig. 1 are shown in phantom. The fold regions 6 each run parallel to the short side 7 of the rectangular jacket section 3. On the long side 8 of the jacket section 3, the ear sections 4 are arranged in pairs opposite one another on the long side 8 of the jacket section 3. Fold areas 6 are also arranged between the static areas 5.2 of the jacket section 3 and the ear sections 4 designed as static areas, each of which runs parallel to the long side 8 of the jacket section 3.

Die Ohrenabschnitte 4 weisen jeweils eine Lasche 9.1 auf. Die Laschen 9 sind dazu eingerichtet, mit den Ausnehmungen 10.1 in Eingriff gebracht zu werden, um in dem mit Bezug auf die Fig. 2a bis 2c beschriebenen Körperzustand des Grundbogens die Position und/oder Ausrichtung der statischen Bereiche 5, insbesondere der Ohrenabschnitte 4 zu den statischen Bereichen 5.1, 5.2, 5.3 zu fixieren. Dazu können die Laschen 9 ohne eine Verformung oder unter einer geringfügigen Verformung mit den ersten Ausnehmungen 10.1 in dem mittleren statischen Bereich 5.3 des Mantelabschnitts 3 zum Eingriff gebracht werden. Ggf. sind zwischen den Laschen 9.1 und den Ohrenabschnitten 4 weitere, in der Darstellung der Fig. 1 jedoch nicht im Detail gezeigte Faltbereiche vorgesehen.The ear sections 4 each have a tab 9.1. The tabs 9 are designed to be brought into engagement with the recesses 10.1 in order to, in relation to the Figures 2a to 2c To fix the position and / or alignment of the static areas 5, in particular the ear sections 4, with respect to the static areas 5.1, 5.2, 5.3. For this purpose, the tabs 9 can be brought into engagement with the first recesses 10.1 in the central static area 5.3 of the jacket section 3 without any deformation or with a slight deformation. If necessary, between the tabs 9.1 and the ear sections 4 are further, in the illustration of Fig. 1 however, not shown in detail folding areas provided.

Zudem weist der in der Darstellung der Fig. 1 unterste statische Bereich 5.1 des Mantelabschnitts 3 eine weitere Lasche 9.2 auf, die über einen entsprechenden Faltbereich 6 mit dem statischen Bereich 5.1 verbunden ist. Die zu der Lasche 9.2 gehörige Ausnehmung 10.2 ist in dem in der Fig. 1 oben dargestellten statischen Bereich 5.1 des Mantelabschnitts 3 ausgebildet und angeordnet. Auch das Paar bestehend aus Ausnehmung 10.2 und Lasche 9.2 sorgt, wie mit Bezug auf die Fig. 2 noch eingehender beschrieben wird, dafür, dass im Körperzustand des Grundbogens des Faltkörpers 1 die Position und/oder Ausrichtung der statischen Bereiche 4, 5.1, 5.2, 5.3 zueinander fixiert wird.In addition, in the representation of the Fig. 1 Lowermost static area 5.1 of the jacket section 3 has a further tab 9.2, which is connected to the static area 5.1 via a corresponding folding area 6. The recess 10.2 belonging to the tab 9.2 is in the Fig. 1 above-illustrated static area 5.1 of the jacket section 3 is formed and arranged. Also the pair consisting of recess 10.2 and tab 9.2 provides, as with reference to Fig. 2 will be described in more detail, so that in the body state of the base curve of the folding body 1, the position and / or alignment of the static areas 4, 5.1, 5.2, 5.3 is fixed to one another.

Die Anordnung und Ausgestaltung der Paare bestehend aus den Ausnehmungen 10.1 und den Laschen 9.1 der Ohrenabschnitte 4 ist unter anderem für die Ausbildung der Kreuzform von Teilen der lastübertragenden Struktur im Körperzustand des Grundbogens 2verantwortlich. Dementsprechend weisen auch die Ausnehmungen 10.1 zueinander eine Kreuzform auf, welche auf den Diagonalen des entsprechend quadratisch ausgebildeten statischen Bereichs 5.3 um den Schnittpunkt der Diagonalen herum angeordnet sind. Folglich sind auch die Laschen 9.1 auf den jeweiligen Ohrenabschnitten 4 auf einer Seite des Matelabschnitts 3 zueinander gewandt angeordnet. Neben den Ausnehmungen 10.1 und 10.2 weist der Grundbogen 2 noch Falteinschnitte 14 auf, die die Überführung des Grundbogens 2 in den jeweiligen Zustand erleichtern.The arrangement and configuration of the pairs consisting of the recesses 10.1 and the tabs 9.1 of the ear sections 4 is responsible, among other things, for the formation of the cross shape of parts of the load-transferring structure in the body state of the base arch 2. Correspondingly, the recesses 10.1 also have a cross shape to one another, which are arranged on the diagonals of the correspondingly square static area 5.3 around the intersection of the diagonals. Consequently, the tabs 9.1 on the respective ear sections 4 on one side of the matel section 3 are also arranged facing one another. In addition to the recesses 10.1 and 10.2, the base sheet 2 also has fold incisions 14 which facilitate the transfer of the base sheet 2 into the respective state.

Fig. 2a zeigt den Faltkörper 1 in dem Körperzustand des Grundbogens 2. In der perspektivischen Darstellung der Fig. 2a bildet die obere Seite des Faltkörpers eine Lasteintragsfläche 11 aus, auf der eine Last abgestellt oder befestigt werden kann, wobei die Last über die unterhalb der Lasteintragsfläche 11 angeordnete lastübertragende Struktur 12 abgeleitet wird. Im Beispiel der Fig. 2a ist die Lasteintragsfläche 11 durch zwei statische Bereiche 5.1 des Mantelabschnitts 3 gebildet. Bei den zwei statischen Bereichen 5.1 des Mantelabschnitts 3, welche die Lasteintragsfläche 11 ausbilden, handelt es sich um die zwei äußeren statischen Bereiche 5.1, wie sie in der Fig. 1 dargestellt sind. Dies wird auch anhand der Lasche 9.2 ersichtlich, welche im Körperzustand des Grundbogens 2 mit der Ausnehmung 10.2 in Eingriff gebracht ist, wobei dazu der Faltbereich 6 zwischen der in der Darstellung der Fig. 2 zu aller oberst angeordneten statischen Bereiche 5.1 und der Lasche 9.2 gefaltet oder umgeformt wurde. Wie in der Darstellung der Fig. 2a erkenntlich, sorgt der Eingriff der Lasche 9.2 in der Ausnehmung 10.2 einerseits dafür, dass die beiden statischen Bereiche 5.1, welche die Lasteintragsfläche 11 ausbilden, relativ zueinander fixiert sind und parallel zueinander aufeinander aufliegen. Darüber hinaus sorgt der Eingriff zwischen der Lasche 9.2 und der Ausnehmung 10.2 jedoch auch dafür, dass die im Körperzustand des Grundbogens 2 miteinander in Eingriff stehenden, in der Darstellung der Fig. 2a jedoch nicht dargestellten Paare der Laschen 9.1 der Ohrenabschnitte 4 und der Ausnehmungen 10.1 im statischen Bereich 5 miteinander in dem hergestellten Eingriff verbleiben. Fig. 2a shows the folding body 1 in the body state of the base sheet 2. In the perspective view of FIG Fig. 2a the upper side of the folded body forms a load application surface 11 on which a load can be placed or fastened, the load being diverted via the load-transferring structure 12 arranged below the load application surface 11. In the example of the Fig. 2a the load application surface 11 is formed by two static areas 5.1 of the jacket section 3. The two static areas 5.1 of the jacket section 3, which form the load application surface 11, are the two outer static areas 5.1, as shown in FIG Fig. 1 are shown. this will can also be seen from the tab 9.2, which is brought into engagement with the recess 10.2 in the body state of the base sheet 2, with the folding area 6 between the areas shown in FIG Fig. 2 to all of the uppermost static areas 5.1 and the tab 9.2 was folded or reshaped. As in the representation of the Fig. 2a As can be seen, the engagement of the tab 9.2 in the recess 10.2 ensures, on the one hand, that the two static areas 5.1, which form the load application surface 11, are fixed relative to one another and lie parallel to one another. In addition, however, the engagement between the tab 9.2 and the recess 10.2 also ensures that those which are in engagement with one another in the body state of the base arch 2, in the illustration of FIG Fig. 2a however, pairs of tabs 9.1 of the ear sections 4 and the recesses 10.1 in the static area 5, which are not shown, remain in the engagement established with one another.

Dadurch wird von den Ohrenabschnitten 4 ein Teil der unterhalb der Lasteintragsfläche 11 angeordneten lastübertragenden Struktur 12 ausgebildet, die eine Kreuzform aufweist und damit besonders dazu geeignet ist, die auf der Lasteintragsfläche 11 ruhende oder auf diese einwirkende Last zu übertragen. Dazu stehen die statischen Bereiche in Form der Ohrenabschnitte 4 senkrecht auf der Lasteintragsfläche 11. Zudem wird die lastübertagende Struktur auch durch die weiteren statischen Bereiche 5.2 gebildet, die ebenfalls senkrecht zur Lasteintragsfläche 11 unterhalb der Lasteintragslastfläche 11 angeordnet sind. Schließlich bildet der statische Bereich 5.3 des Mantelabschnitts 3 einen Boden des Faltkörpers im Körperzustand des Grundbogens 2 aus. Der surch den statischen Bereich 5.3 gebildete boden verläuft dabei parallel zur Laseintragsfläche 11.As a result, part of the load-transferring structure 12 arranged below the load-bearing surface 11 is formed by the ear sections 4, which has a cross shape and is therefore particularly suitable for transferring the load resting on or acting on the load-bearing surface 11. For this purpose, the static areas in the form of the ear sections 4 are perpendicular to the load application area 11. In addition, the load-transferring structure is also formed by the further static areas 5.2, which are also arranged perpendicular to the load application area 11 below the load application load area 11. Finally, the static area 5.3 of the jacket section 3 forms a bottom of the folded body in the body state of the base sheet 2. The floor formed by the static area 5.3 runs parallel to the laser entry surface 11.

Damit bilden die statischen Bereiche 5.1, 5.2, 5.3 des Mantelabschnitts 3 des Grundbogens 2 in der in der Fig. 2 dargestellten Körperzustand des Faltkörpers 1 einen Quader, insbesondere einen Würfel aus, der an zwei gegenüberliegenden Seiten 13 offen ist, von denen jedoch in der Darstellung der Fig. 2a nur eine Seite zu sehen ist.Thus, the static areas 5.1, 5.2, 5.3 of the jacket section 3 of the base sheet 2 in the in the Fig. 2 illustrated body condition of the Folded body 1 is a cuboid, in particular a cube, which is open on two opposite sides 13, of which, however, in the illustration of the Fig. 2a only one side can be seen.

Bezüglich der Faltbereiche 6 zwischen den statischen Bereichen 5.1, 5.2, 5.3 des Mantelabschnitts 3 führt die Überführung des Faltkörpers aus dem Flachzustand in den Körperzustand dazu, dass die Faltbereiche 6 jeweils eine Faltung oder Umformung um 90° erfahren. Die Faltbereiche 6 zwischen den statischen Bereichen 5.2 und den Ohrenabschnitten 4 bilden im Körperzustand des Grundbogens 2 mit dem jeweiligen statischen Bereich 5 einen Winkel von 135° aus. Durch die Ohrenabschnitte 4, die senkrecht zur Lasteintragsfläche 11 eine Kreuzform ausbilden und den ebenfalls senkrecht zur Lasteintragsfläche 11 unterhalb dieser angeordneten statischen Bereiche 5.2 wird eine lastübertragende Struktur 12 ausgebildet, die sehr effektiv die auf der Lasteintragsfläche 11 ruhenden Kräfte und Belastungen aufnehmen und ableiten kann. Durch die doppellagig, also durch zwei statische Bereiche 5.1 gebildete, Lasteintragsfläche 11 wird zudem erreicht, dass die Lasteintragsfläche 11 besonders widerstandfähig und robust gegenüber darauf einwirkenden Lasten und Kräften ist. Dementsprechend kann der Faltkörper in dem in der Fig. 2 dargestellten Körperzustand des Grundbogens 2 beispielsweise als Stuhl, Hocker oder dergleichen eingesetzt werden, wobei dann der Benutzer die Lasteintragsfläche 11 als Sitzfläche verwendet.With regard to the folding areas 6 between the static areas 5.1, 5.2, 5.3 of the jacket section 3, the transfer of the folded body from the flat state to the body state leads to the folding areas 6 each being folded or deformed by 90 °. The folding areas 6 between the static areas 5.2 and the ear sections 4 form an angle of 135 ° with the respective static area 5 in the body state of the base arch 2. The ear sections 4, which form a cross shape perpendicular to the load application surface 11 and the static areas 5.2 also arranged perpendicular to the load application surface 11 below this, form a load-transmitting structure 12 which can very effectively absorb and dissipate the forces and loads resting on the load application surface 11. As a result of the double-layered load application area 11 formed by two static areas 5.1, it is also achieved that the load application area 11 is particularly resistant and robust to loads and forces acting on it. Accordingly, the folding body in the in the Fig. 2 shown body state of the base arch 2 can be used, for example, as a chair, stool or the like, the user then using the load application surface 11 as a seat surface.

Die Darstellung der Fig. 2b zeigt eine Seitenansicht des Faltkörpers 1 mit Blick auf die offene Seite 13 des durch den Mantelabschnitt 3 und dessen statische Bereiche 5.1, 5.2, 5.3 ausgebildeten Quaders oder Würfels. Neben der Lasteintragsfläche 11 sind die den Teil der lastübertragenden Struktur 12 bildenden, in einer Kreuzform zueinander angeordneten Ohrenabschnitte 4 dargestellt.The representation of the Figure 2b shows a side view of the folding body 1 with a view of the open side 13 of the parallelepiped or cube formed by the jacket section 3 and its static areas 5.1, 5.2, 5.3. In addition to the load application surface 11, the ear sections 4, which form part of the load-transferring structure 12 and are arranged in a cross shape with respect to one another, are shown.

Die Fig. 2c zeigt die Draufsicht auf die Lasteintragsfläche 11 im Körperzustand des Grundbogens 2 des Faltkörpers 1. In der Fig. 2c ist abermals dargestellt, wie die Lasche 9.2, welche an dem statischen Bereich 5.1 angeformt ist, mit der Ausnehmung 10.2 im Eingriff steht, welche an der im Flachzustand des Grundbogens am anderen Ende des Mantelabschnitts 3 angeordneten statischen Bereichs 5.1 ausgebildet ist. Die Lasteintragsfläche 11 weist im Beispiel der Fig. 2 eine annähernd quadratische Fläche auf, die insbesondere bei einer Anwendung als Hocker eine Kantenlänge K von 220mm betragen kann. Die Fläche der jeweiligen statischen Bereiche 5.1, 5.2, 5.3 oder ihre jeweilige Kantenlänge kann geringfügig kleiner ausfallen. Beispielsweise kann vorgesehen sein, dass die lange Seite 8 des Mantelabschnitts 3 einschließlich der Lasche 9.2, der statischen Bereiche 5.1, 5.2, 5.3 und der dazwischen angeordneten Faltbereiche eine länge von 1070mm bis 1080mm aufweist, was in ungefähr eine Kantenlänge K der statischen Bereiche 5.1, 5.2, 5.3 von 211mm bis 213mm entspricht.the Figure 2c shows the top view of the load application surface 11 in the body state of the base arch 2 of the folded body 1. In FIG Figure 2c is again shown how the tab 9.2, which is formed on the static area 5.1, engages with the recess 10.2, which is formed on the static area 5.1 arranged at the other end of the jacket section 3 when the base sheet is flat. The load application area 11 has in the example of Fig. 2 an approximately square area, which can have an edge length K of 220mm, especially when used as a stool. The area of the respective static areas 5.1, 5.2, 5.3 or their respective edge length can be slightly smaller. For example, it can be provided that the long side 8 of the jacket section 3 including the tab 9.2, the static areas 5.1, 5.2, 5.3 and the folding areas arranged between them has a length of 1070mm to 1080mm, which is approximately an edge length K of the static areas 5.1, 5.2, 5.3 corresponds from 211mm to 213mm.

Die Fig. 3a zeigt die Draufsicht auf den Faltkörper 1 im Packzustand des Grundbogens 2. Wie aus der Fig. 3 hervorgeht, ist im Packzustand des Grundbogens 2 die Fläche des Faltkörpers 1 im Wesentlichen rechteckig und weist eine Kantenlänge K1, K2 auf, welche 330mm, insbesondere 300mm, besonders bevorzugt 250mm nicht übersteigt. In der beispielhaften Darstellung der Fig. 2a kann beispielsweise vorgesehen sein, dass die Kantenlänge K1 224mm und die Kantenlänge K2 220mm umfasst. Dementsprechend ist im Packzustand des Grundbogens 2 des Faltkörpers 1 eine sehr kompakte Fläche möglich, welcher das Transportieren des Faltkörpers 1 im Packzustand des Grundbogens 2 ermöglicht oder erleichtert. Bevorzugt ist die Fläche des Faltkörpers 1 im Packzustand des Grundbogens 2 5% bis 10%, besonders bevorzugt 7% bis 9%, größer als die Fläche der statischen Elemente 5.1, 5.2, 5.3 des Mantelabschnitts 3. Mit anderen Worten ausgedrückt ist die Fläche des Faltkörpers 1 im Packzustand des Grundbogens 2 1% bis 3% größer als die Fläche der Lasteintragsfläche 11 des Faltkörpers 1 im Körperzustand. Ebenfalls ist in Fig. 3a ersichtlich, dass die Laschen 9.1 an der gleichen Seite des Faltkörpers angeordnet sind.the Fig. 3a shows the top view of the folding body 1 in the packing state of the base sheet 2. As shown in FIG Fig. 3 is apparent, in the pack state of the base sheet 2, the area of the folding body 1 is essentially rectangular and has an edge length K 1 , K 2 which does not exceed 330 mm, in particular 300 mm, particularly preferably 250 mm. In the exemplary representation of the Fig. 2a For example, it can be provided that the edge length K 1 is 224 mm and the edge length K 2 is 220 mm. Accordingly, in the packed state of the base sheet 2 of the folding body 1, a very compact surface is possible, which enables or facilitates the transport of the folded body 1 in the packed state of the base sheet 2. The area of the folding body 1 in the packed state of the base sheet 2 is preferably 5% to 10%, particularly preferably 7% to 9%, greater than the area of the static elements 5.1, 5.2, 5.3 of the Shell section 3. In other words, the area of the folded body 1 in the pack state of the base sheet 2 is 1% to 3% larger than the area of the load application surface 11 of the folded body 1 in the body state. Is also in Fig. 3a it can be seen that the tabs 9.1 are arranged on the same side of the folding body.

Bevorzugt ist die Fläche A12 des Faltkörpers 1 im Packzustand des Grundbogens 2 lediglich 5% größer, besonders bevorzugt lediglich 2% größer als die Fläche Ak der Lasteintragsfläche 11 im Körperzustand des Faltkörpers 1. Dadurch wird ein sehr kompaktes Packmaß des Faltkörpers 1 im Packzustand im Bezug auf die Größe der Lasteintragsfläche 11 im Körperzustand des Faltkörpers 1 erreicht. Folglich kann der Faltkörper leicht mitgeführt werden und bietet gleichzeitig eine ausreichend große Lasteintragsfläche 11.The area A 12 of the folding body 1 in the packing state of the base sheet 2 is preferably only 5% larger, particularly preferably only 2% larger than the area A k of the load application area 11 in the body state of the folding body 1. This results in a very compact packing size of the folding body 1 in the packed state achieved in relation to the size of the load application area 11 in the body state of the folded body 1. As a result, the folding body can easily be carried along and at the same time offers a sufficiently large load application area 11.

In der Seitenansicht der Fig. 3b, welche ebenfalls den Packzustand des Grundbogens 2 zeigt, ist einerseits erkennbar, dass die Faltbereiche 6 zwischen den statischen Bereichen 5.1, 5.2, 5.3 des Mantelabschnitts 3 jeweils in abwechselnde Richtungen um 180° gefaltet sind und dass dadurch die statischen Bereiche 5 des Mantelabschnitts 3 im Wesentlichen deckungsgleich übereinander angeordnet sind. Ebenfalls ist anhand der schematisch dargestellten, an den Ohrenabschnitten 4 angeordneten Laschen 9.1 ersichtlich, dass im Packzustand des Grundbogens 2 die Faltbereiche zwischen den Ohrenabschnitten 4 und den statischen Bereichen 5.2 des Mantelabschnitts 3 ebenfalls eine 180°-Faltung aufweisen und die Ohrenabschnitte 4 sich zumindest abschnittsweise überlappend zwischen je zwei, insbesondere aneinander angrenzenden, statischen Bereichen 5.1, 5.2, 5.3 des Mantelabschnitts 3 befinden. Dadurch wird ein besonders kompakter und platzsparender Packzustand des Grundbogens 2 des Faltkörpers 1 erreicht, sodass im Packzustand des Grundbogens 2 die Höhe H des Faltkörpers 1 das achtfache bis zwölf-fache der Stärke S des Grundbogens 2 beträgt. In der Fig. 3 kann beispielsweise vorgesehen sein, dass die Stärke S des Grundbogens 4mm beträgt und dass die Höhe h des Faltkörpers in Packzustand des Grundbogens 2 lediglich 38mm beträgt. Damit lässt sich der Faltkörper 1 im Packzustand sowohl aufgrund der geringen Höhe H, als auch aufgrund der geringen Flächenausdehnung, welche durch die Kantenlänge K1 und K2 bestimmt werden, besonders kompakt verstauen und bequem mitführen, beispielsweise in einer Handtasche, Aktentasche oder dergleichen.In the side view of the Figure 3b , which also shows the packing state of the base sheet 2, it can be seen on the one hand that the folding areas 6 between the static areas 5.1, 5.2, 5.3 of the jacket section 3 are each folded in alternating directions by 180 ° and that as a result, the static areas 5 of the jacket section 3 in Are arranged essentially congruently one above the other. It can also be seen from the schematically shown tabs 9.1 arranged on the ear sections 4 that when the base sheet 2 is packed, the fold areas between the ear sections 4 and the static areas 5.2 of the jacket section 3 also have a 180 ° fold and the ear sections 4 are at least partially overlapping between two, in particular adjoining, static areas 5.1, 5.2, 5.3 of the jacket section 3. As a result, a particularly compact and space-saving packing condition of the base sheet 2 of the folding body 1 is achieved, so that in the packing condition of the base sheet 2 the height H of the folding body 1 is eight times as high up to twelve times the strength S of the base sheet 2. In the Fig. 3 For example, it can be provided that the thickness S of the base sheet is 4mm and that the height h of the folding body in the packed state of the base sheet 2 is only 38mm. In this way, the folding body 1 can be stowed in a particularly compact manner in the packed state both due to the low height H and due to the small area, which is determined by the edge lengths K 1 and K 2 , for example in a handbag, briefcase or the like.

In Fig. 3c sind abermals in einer Seitenansicht des Packzustands des Grundbogens die Faltbereiche 6 zwischen den statischen Bereichen 5.1, 5.2, 5.3 und den Ohrenabschnitten 4 dargestellt. Dabei ist einerseits erkennbar, dass diese Faltbereich ebenfalls eine 180°-Faltung aufweisen. Außerdem ist erkennbar, dass die Ohrenabschnitte 4 zumindest abschnittsweise überlappend jeweils übereinander angeordnet sind und angrenzend an die zumindest teilweise überlappende Anordnung der jeweils zwei Ohrenabschnitte 4 auf beiden Seiten jeweils ein statischer Abschnitt 5..1, 5.2, 5.3 des Mantelabschnitts 3 zur Anlage kommt.In Figure 3c the folding areas 6 between the static areas 5.1, 5.2, 5.3 and the ear sections 4 are again shown in a side view of the packing state of the base sheet. On the one hand, it can be seen that this folding area also has a 180 ° fold. It can also be seen that the ear sections 4 overlap at least in sections and that a static section 5..1, 5.2, 5.3 of the jacket section 3 comes to rest adjacent to the at least partially overlapping arrangement of the two ear sections 4 on both sides.
