Description

Die Erfindung betrifft ein Belüftungssystem für ein Gebäude, aufweisend einen Quellauslass, der eine luftdurchlässige Quellfläche aufweist, durch die in einem Belüftungszustand dem Belüftungssystem zugeführte Luft in einen Innenraum des Gebäudes einleitbar ist. Ein Belüftungssystem gemäß dem Oberbegriff des Anspruchs 1 ist aus der US-B1-6 280 320 bekannt.The invention relates to a ventilation system for a building, comprising a source outlet, which has an air-permeable source surface, through which air supplied to the ventilation system in an aeration state can be introduced into an interior space of the building. A ventilation system according to the preamble of claim 1 is known from US-B1-6,280,320 known.

Derartige Belüftungssysteme haben insbesondere durch ihre textilen Quellflächen den Vorteil, den Austritt laminarer Luftströmung, vor allem bei geringen Austrittsgeschwindigkeiten der Luft von 0,01 m/s bis 1,8 m/s, zu erlauben. Die Luft diffundiert durch das textile und luftdurchlässige Gewebe der Quellfläche gleichmäßig in den Raum und verdrängt dabei die Raumluft. Derartige Belüftungssysteme werden wegen der beschriebenen Verdrängungswirkung zum Beispiel in Großküchen, der Druckindustrie oder in Fertigungshallen mit erhöhtem Staubaufkommen eingesetzt. Um einen raschen, turbulenzfreien und impulsarmen Luftaustausch zu erreichen, ist es jedoch wegen der geringen Austrittsgeschwindigkeit erforderlich, die Quellfläche vergleichsweise groß zu gestalten.Such ventilation systems have the advantage, in particular by their textile swelling surfaces, of allowing the exit of laminar air flow, especially at low exit velocities of the air from 0.01 m / s to 1.8 m / s. The air diffuses through the textile and air-permeable fabric of the source surface evenly into the room and displaces the air in the room. Such ventilation systems are used because of the displacement effect described, for example, in commercial kitchens, the printing industry or in production halls with increased dust. To achieve a rapid, turbulence-free and low-pulse air exchange, however, it is necessary because of the low exit velocity to make the source area comparatively large.

Obwohl die genannten Quellauslässe auch gestalterische Möglichkeiten für Innenräume von Gebäuden eröffnen, bilden sie dennoch zunächst eine nachteilige Einschränkung der Innenraumarchitektur und sind deshalb oftmals mit architektonischen Belangen nicht zu vereinbaren. Insbesondere ist bei einem Betrieb derartiger Quellauslässe darauf zu achten, dass der Luftaustritt nicht durch den Quellauslass verdeckende Hindernisse eingeschränkt wird.Although the aforementioned source outlets also open up creative possibilities for interior spaces of buildings, they nevertheless initially constitute a disadvantageous restriction of interior architecture and are therefore often incompatible with architectural concerns. In particular, care should be taken in an operation of such Quellauslässe that the air outlet is not limited by the Quellauslass obscuring obstacles.

Für die Verdrängung großer Luftmassen innerhalb kurzer Zeit, etwa um im Brandfall und damit einhergehender Rauchentwicklung Fluchtwege und Löschangriffe zu sichern und Personen zu schützen, werden die an sich geeigneten textilen Quellauslässe wegen der genannten Nachteile jedoch nicht verwendet.For the displacement of large air masses within a short time, about to secure in the event of fire and concomitant smoke escape routes and firefighting attacks and protect people, the per se suitable textile Quellauslässe are not used because of the disadvantages mentioned.

Eine Entrauchung von Gebäuden im Brandfall, etwa mittels Abzugsvorrichtungen (üblicherweise Ventilatoren und Dachluken) ist gesetzlich geregelt. Dennoch wird die Luftnachführung bekanntermaßen vernachlässigt, wodurch wiederum der Rauchabzug behindert wird.A smoke extraction of buildings in case of fire, for example by means of exhaust devices (usually fans and skylights) is regulated by law. Nevertheless, the air tracking is known to be neglected, which in turn hinders the flue.

Aufgabetask

Der Erfindung liegt die Aufgabe zugrunde, ein Belüftungssystem insbesondere für den Brandfall vorzuschlagen, das es ohne besondere architektonische Einschränkungen gestattet, Quellauslässe mit großen Quellflächen, zur großflächigen, impulsarmen Belüftung von Innenräumen von Gebäuden zu verwenden.The invention has for its object to propose a ventilation system, especially for the case of fire, which allows it without special architectural restrictions to use source outlets with large source areas for large-scale, low-impulse ventilation of interiors of buildings.

Lösungsolution

Ausgehend von den bekannten Belüftungssystemen wird nach der Erfindung vorgeschlagen, dass der Quellauslass, ausgehend von einem Ruhezustand, in dem der Quellauslass durch Faltung, Aufrollen oder Raffung in seinem Volumen verkleinert ist, durch die in den Quellauslass einströmende Luft in seinem Volumen vergrößerbar und in einen Belüftungszustand überführbar ist.Starting from the known ventilation systems is proposed according to the invention that the Quellauslass, starting from a rest state in which the source outlet is reduced by folding, rolling or gathering in its volume, enlarged by the air flowing into the source outlet in its volume and in a Ventilation state is feasible.

Der erfindungsgemäße textile Quellauslass wirkt als Verdrängungsauslass und kann während äußerer Notsituationen in Innenräumen von Gebäuden, etwa im Falle eines Brandes oder einer Rauchentwicklung sehr wirksam eingesetzt werden, da er, anders als etwa Schlitzauslässe, keinerlei Induktionswirkung zeigt und eine Durchmischung von zugeführter und in dem Innenraum befindlicher Luft, die etwa mit Rauch oder gefährlichen Gasen kontaminiert sein kann, aus diesem Grund nicht zu befürchten ist. Im Brandfall, also im Belüftungszustand, werden selbstverständlich architektonische Belange hintangestellt, so dass sehr große Quellflächen verwendet werden und optische Nachteile im Belüftungszustand außer Acht bleiben können.The textile Quellauslass invention acts as a displacement outlet and can be used very effectively during external emergencies in interiors of buildings, such as in the case of fire or smoke, since he, unlike slot outlets, no induction effect and shows a mixing of supplied and in the interior air, which may be contaminated with smoke or hazardous gases, for this reason is not to be feared. In case of fire, ie in the ventilation state, of course, architectural concerns are placed in the background, so that very large source areas are used and optical disadvantages in the ventilation state can be ignored.

Im Ruhezustand hingegen ist der Quellauslass gefaltet, aufgerollt oder gerafft, also auf im Wesentlichen das Volumen verkleinert, welches von dem Quellauslassmaterial selbst eingenommen wird. Der Quellauslass ist somit entsprechend wenig störend für die Innenraumgestaltung.In the rest state, however, the source outlet is folded, rolled up or gathered, that is to say reduced to essentially the volume which is taken up by the source outlet material itself. The Quellauslass is thus correspondingly little disturbing to the interior design.

Vorzugsweise ist in einer Fortbildung der Erfindung vorgesehen, dass der Quellauslass, ausgehend von dem Ruhezustand, in dem er in einer Lagervorrichtung gelagert ist, durch einen Öffnungsquerschnitt der Lagervorrichtung in den Innenraum verlagerbar und dadurch in den Belüftungszustand überführbar ist.Preferably, it is provided in a development of the invention that the source outlet, starting from the idle state in which it is mounted in a storage device, is displaceable through an opening cross section of the storage device in the interior and thereby can be converted into the ventilation state.

Im Ruhezustand ist der Quellauslass in der Lagervorrichtung gelagert und vor Verschmutzung, insbesondere Staubablagerung, wirksam geschützt. Der Quellauslass ist im Ruhezustand vorzugsweise gefaltet in der Lagervorrichtung gelagert und im Belüftungszustand durch die in den Quellauslass einströmende Luft auf sein volles Volumen zu entfalten. Durch die Faltung des Quellauslasses kann die Lagervorrichtung äußerst raumsparend ausgeführt sein und dementsprechend leicht auch sehr ambitionierten architektonischen Vorgaben angepasst werden. Die Entfaltung geschieht im übrigen vorzugsweise ausschließlich mittels der in den Quellauslass einströmende Luft. Auf besondere Mittel, die die Entfaltung unterstützen, etwa Federelemente, kann verzichtet werden.At rest, the source outlet is stored in the storage device and effectively protected against contamination, especially dust deposition. The source outlet is preferably stored folded in the storage device in the idle state and unfold in the ventilation state by the air flowing into the source outlet to its full volume. By folding the Quellauslasses the storage device can be designed extremely space-saving and accordingly easily adapted to very ambitious architectural specifications. The unfolding, moreover, preferably takes place exclusively by means of the air flowing into the source outlet. On special means that support the unfolding, such as spring elements, can be dispensed with.

Bevorzugt soll das Belüftungssystem in einer Weiterbildung der Erfindung derart ausgebildet sein, dass sich der Öffnungsquerschnitt in der Ebene der Innenraumdecke oder -wand befindet, um eine im Brandfall gefährliche Verdeckung durch Möbel, Maschinen oder andere im Innenraum befindliche Gegenstände wirksam auszuschließen.Preferably, the ventilation system should be formed in a development of the invention such that the opening cross-section is in the plane of the interior ceiling or wall to effectively exclude dangerous in case of fire masking by furniture, machinery or other objects located in the interior.

In einer favorisierten Weiterbildung ist noch vorgesehen, dass sich das Belüftungssystem und/oder der Quellauslass zumindest teilweise innerhalb einer Zwischendecke und dass der Quellauslass sich zumindest im Belüftungszustand innerhalb des Innenraumes befindet. Durch die Lagerung des Quellauslasses innerhalb der Zwischendecke kann das Belüftungssystem und/oder der Quellauslass sehr leicht den Blicken verborgen werden und demzufolge die Innenraumgestaltung optisch nicht oder nur wenig beeinträchtigen.In a preferred development, it is also provided that the ventilation system and / or the source outlet is at least partially within a false ceiling and that the source outlet is at least in the ventilation state within the interior. Due to the storage of the Quellauslasses within the false ceiling, the ventilation system and / or the Quellauslass can be very easily hidden from view and therefore visually impair the interior design or only slightly.

Besonders bevorzugt ist bei einer Fortbildung der Erfindung, dass die Verlagerung des Quellauslass zumindest zum Teil durch seine eigene Gewichtskraft bewirkt wird, da eine derartige Verlagerung ohne Zuführung weiterer Energie vonstatten gehen kann.In a further development of the invention, it is particularly preferred that the displacement of the source outlet be effected at least in part by its own weight force, since such a displacement can take place without the supply of additional energy.

Die Quellfläche des Quellauslasses im Belüftungszustand hat mindestens abschnitts- oder segmentweise bevorzugt die Form eines vorzugsweise langgestreckten Zylinders oder Teilzylinders eines Kegels oder einer Kugel, um ein besonders günstiges, das heißt geringes, Volumen-Quellflächenverhältnis zu erreichen.The source surface of the source outlet in the aeration state preferably has the shape of a preferably elongate cylinder or partial cylinder of a cone or a sphere, at least in sections or segments, in order to achieve a particularly favorable, ie low, volume swelling area ratio.

Eine vorteilhafte Fortbildung der Erfindung sieht zudem vor, dass der Quellauslass in der Ruhestellung von einer im Bereich des Öffnungsquerschnitts befindlichen Rückhaltevorrichtung in der Lagervorrichtung zurückgehalten wird und von dieser vorzugsweise unsichtbar abgedeckt wird. Die Rückhaltevorrichtung kann beispielsweise eine Abdeckung in Form eines Deckels oder einer Klappe sein oder aber aus einer Mehrzahl von entlang des Öffnungsquerschnitts gelagerten flexiblen Rtickhaltezapfen bestehen.An advantageous development of the invention also provides that the source outlet is retained in the rest position by a located in the region of the opening cross-section retainer in the storage device and is preferably covered by this invisible. The retaining device can, for example, a cover in Form of a lid or a flap or consist of a plurality of along the opening cross-section mounted flexible Rtickhaltezapfen.

Vorzugsweise ist das Belüftungssystem so ausgebildet, dass die Rückhaltevorrichtung eine Abdeckung ist, die durch die die Entfaltung des Quellauslasses und/oder durch einen Antrieb zu öffnen ist, wobei der Antrieb ein elektrischer, mechanischer, elektromechanischer oder chemischer, hydraulischer oder pneumatischer ist. Beispielsweise kann die Rückhaltevorrichtung als ein Deckel ausgebildet sein, der mit oder ohne ein Scharnier im Ruhezustand auf dem Rand des Öffnungsquerschnitts befestigt ist und der allein durch einen von dem Quellauslass ausgeübten Druck zu öffnen und dadurch in den Belüftungszustand überführbar ist.Preferably, the ventilation system is designed so that the retaining device is a cover which is to be opened by the deployment of the Quellauslasses and / or by a drive, wherein the drive is an electrical, mechanical, electromechanical or chemical, hydraulic or pneumatic. For example, the retaining device may be formed as a lid, which is fastened with or without a hinge in the resting state on the edge of the opening cross-section and which can be opened only by a pressure exerted by the source outlet pressure and thereby in the ventilation state.

Eine vorteilhafte Fortbildung der Erfindung sieht zudem vor, dass der Antrieb durch Auftreten eines Brandes oder durch Rauchentwicklung auslösbar ist, so dass die Rückhaltevorrichtung schon geöffnet ist, wenn der Quellauslass von dem Ruhezustand in den Belüftungszustand überführt wird. Die Auslösung kann im übrigen etwa mittels eines an sich bekannten Rauchmelders erfolgen.An advantageous development of the invention also provides that the drive can be triggered by the occurrence of a fire or by smoke, so that the restraint device is already open when the source outlet is transferred from the idle state to the aeration state. The release can be done otherwise by means of a known per se smoke detector.

Eine Fortbildung des Quellauslasses schlägt zudem vor, dass der Quellauslass im Belüftungszustand mittels einer Zuführeinrichtung, insbesondere mittels Wasserleitungen und Düsen, befeuchtbar ist, um ein Verbrennen oder Schmelzen des textilen Gewebes des Quellauslasses wirksam zu verhindern.A development of the Quellauslasses also suggests that the source outlet in the ventilation state by means of a feeder, in particular by means of water pipes and nozzles, is moistened to effectively prevent burning or melting of the textile fabric of the Quellauslasses.

Außerdem ist in einer Weiterbildung vorgesehen, dass der Quellauslass im Belüftungszustand über Abstandsmittel von der Lagervorrichtung beabstandbar ist, um dadurch bestimmte Raumbereiche, etwa Galerien oder Notwege, gegenüber rauchhaltiger Luft zu schützen.In addition, it is provided in a development that the source outlet in the ventilation state via spacer means of the storage device is spaced, thereby protecting certain areas of space, such as galleries or emergency routes, against smoke-containing air.

In einer weiteren Ausgestaltung vorgesehen, dass das Abstandsmittel eine luftundurchlässige textile Schürze ist, die mit mindestens einem Zuführkanal für die dem Quellauslass zuzuführende Luft versehen ist. Das Abstandmittel kann aufgrund seiner textilen Beschaffenheit ebenfalls in der Lagervorrichtung gelagert werden, wobei grundsätzlich auch eine Lagerung außerhalb der Lagervorrichtung möglich ist. Das Abstandsmittel kann insbesondere als Schlauch ausgeführt sein, durch den die zugeführte Luft in den Quellauslass und weiter durch dessen Quellfläche in den Innenraum einleitbar ist. Der Begriff "textil" ist für die Erfindung weit auszulegen; auch teiltextile Materialien sind, sofern sie luftdurchlässig sind und einen laminaren Luftdurchtritt erlauben, ebenfalls mit einbezogen. Grundsätzlich sind auch die folgenden Materialien für eine Verwendung als Quellauslass geeignet: Metallgewebe, perforierte dünne Metallbleche, mikroperforierte Folien aus Kunststoff oder Metall oder auch (vorzugsweise feuerfeste) Naturmaterialien.Provided in a further embodiment that the spacer means is an air-impermeable textile apron, which is provided with at least one feed channel for the air to be supplied to the source outlet. The spacer means can also be stored in the storage device due to its textile nature, in principle, a storage outside the storage device is possible. The spacer means may in particular be designed as a tube, through which the supplied air can be introduced into the source outlet and further through its source surface into the interior. The term "textile" is to be interpreted broadly for the invention; Partly textile materials, provided they are permeable to air and allow a laminar passage of air, are also included. In principle, the following materials are also suitable for use as a source outlet: metal mesh, perforated thin metal sheets, microperforated sheets of plastic or metal, or even (preferably refractory) natural materials.

Eine Weiterbildung des erfindungsgemäßen Belüftungssystem ist, dass der Quellauslass in dem Ruhezustand durch mindestens ein Haltemittel, insbesondere ein Band oder eine Schutzfolie, zusammengehalten ist, das durch die Einleitung von Luft in den Quellauslass lösbar ist. Durch die Einleitung der Luft in den Quellauslass ist zudem vorgesehen, dass das Haltemittel eine Zerstörung erfährt, d.h. insbesondere mittels Aufplatzen oder Aufreißen lösbar ist. Es ist dadurch ebenfalls möglich, den Quellauslass sichtbar aufzuhängen, und auf die Lagervorrichtung zu verzichten. Beispielsweise kann der erfindungsgemäße Quellauslass in einer Aussparung der Innenraumwand, etwa einer Mauernische gefaltet sein und bei einem Brandfall herausfallen und sich auf sein volles Volumen entfalten. Die Entfaltung kann neben der Lufteinleitung selbstverständlich auch auf andere Weise initiiert werden, etwa durch die Zündung von Gaspatronen oder durch Klapp- und Federmechanismen, vergleichbar mit einem so genannten Faltschacht bekannter Mittelformatkameras.A development of the ventilation system according to the invention is that the source outlet is held together in the idle state by at least one holding means, in particular a band or a protective film, which is solvable by the introduction of air into the Quellauslass. By the introduction of the air into the Quellauslass is also provided that the holding means undergoes a destruction, i. in particular by bursting or tearing is solvable. It is thus also possible to visibly hang the Quellauslass, and to dispense with the storage device. For example, the Quellauslass invention may be folded in a recess of the interior wall, such as a wall niche and fall out in a fire and unfold to its full volume. The unfolding can of course also be initiated in other ways, in addition to the introduction of air, such as the ignition of gas cartridges or by folding and spring mechanisms, comparable to a so-called folding shaft known medium format cameras.

Das erfindungsgemäße Belüftungssystem lässt sich in sehr vorteilhafter Weise abgesehen von Brandfällen auch zur bedarfsweisen ergänzenden Belüftung von Räumen, insbesondere von Versammlungsstätten wie Konzerthallen, Sporthallen, Hörsälen o.ä., verwenden. Während für die Belüftung bei "normaler" Raumnutzung eine Lüftungsanlage mit standardmäßigen Luftauslässen (Drallauslässe, Impulsauslässe oder Verdrängungsluftauslässe) vorgesehen ist, kann bei einer besonderen Nutzung der Räumlichkeit, beispielsweise bei einer Großveranstaltung (Konzert, Aufführung o.ä. "Eventbetrieb") - ergänzend möglicherweise aber auch rein alternativ - das erfindungsgemäße Belüftungssystem eingesetzt werden. Im "Eventbetrieb" spielen architektonische Belange, wie sie bei normaler Nutzung eventuell zu berücksichtigen sind, eine untergeordnete Rolle, so dass dann akzeptabel ist, dass der textile Auslass mit einer großen Länge in seinem Betriebszustand innerhalb des Raumes angeordnet ist. Der große Vorteil besteht dann darin, dass sehr große Querschnittsflächen für die Luftzufuhr zur Verfügung stehen, so dass trotz der großen Volumenströme eine zugfreie Belüftung erreicht wird. Im Normalbetrieb der Räumlichkeit kann der Quellauslass des erfindungsgemäßen Belüftungssystems innerhalb des Ruhezustandes verbleiben und tritt daher optisch überhaupt nicht in Erscheinung.The ventilation system according to the invention can be used in a very advantageous manner, apart from fire, for on-demand supplemental ventilation of rooms, in particular of meeting places such as concert halls, sports halls, lecture halls or the like. While a ventilation system with standard air outlets (twist outlets, impulse outlets or displacement air outlets) is provided for the ventilation with "normal" use of space, in a special use of the space, for example at a major event (concert, performance or similar "event operation") - but possibly also purely as an alternative - the ventilation system according to the invention can be used. In "event operation" architectural issues, as they may need to be taken into account in normal use, play a minor role, so that it is then acceptable that the textile outlet is arranged with a large length in its operating state within the room. The big advantage is that very large cross-sectional areas are available for the air supply, so that draft-free ventilation is achieved despite the large volume flows. In normal operation of the premises, the Quellauslass the ventilation system according to the invention remain within the idle state and therefore does not appear visually at all.

Das in Figur 1 gezeigte erfindungsgemäße Belüftungssystem 1 weist einen zylinderförmigen langgestreckten Quellauslass 2 auf, der in einer auch in der Figur 2b gezeigten Belüftungszustand B, deckennah an und parallel zu einer Zwischendecke 3 eines Innenraumes 4 angeordnet ist. Der Quellauslass ist in dem gezeigten Belüftungszustand B auf sein volles Volumen aufgebläht. Die Mantelfläche 5 und die beiden Stirnflächen 6, 7 des Quellauslasses 2 bestehen aus textilem und luftdurchlässigem Material den die Quellfläche 8 des Quellauslasses 2, durch die die Luft von innerhalb des Quellauslasses 2 nach außen in den Innenraum 4 in Richtung der in Figur 2b gezeigten Pfeile 20 eintreten kann. Über dem Quellauslass 2 ist eine Lagervorrichtung 9 aus Metallblech gezeigt, an der der Quellauslass 2 befestigt ist. Die Lagervorrichtung 9 ist innerhalb der Zwischendecke 3 des Innenraumes 4 angeordnet und beansprucht deshalb kein zusätzliches Volumen des Innenraums 4. Die Lagervorrichtung 9 mündet deckenseitig in einen von der Länge 10 und Breite 11 der Lagervorrichtung 9 definierten Öffnungsquerschnitt 12, der sich in einer von der Innenraumdecke 14 gebildeten Ebene befindet. An die Lagervorrichtung 9 schließt sich eine Rückhaltevorrichtung 15 in Form einer aus zwei metallenen Klappen 16, 17 gebildeten Abdeckung an, die im Belüftungszustand B geöffnet ist. Mit Abstand zu der dem Innenraum 4 abgewandten Seite der Lagervorrichtung 9 schließt sich ein Verteilkanal 13 an, in den Luft aus nicht gezeigten Zuleitungsrohren während des Belüftungszustandes eingeleitet wird und auf hier nicht gezeigte aber an sich bekannte Weise weiter dem Quellauslass 2 zugeführt wird.This in FIG. 1 shown ventilation system 1 according to the invention has a cylindrical elongated source outlet 2, which in a also in the FIG. 2b shown ventilation state B, close to the ceiling and parallel to an intermediate ceiling 3 of an interior space 4 is arranged. The source outlet is inflated to its full volume in the aeration state B shown. The lateral surface 5 and the two end faces 6, 7 of the Quellauslasses 2 are made of textile and luftdurchlässigem material the source surface 8 of the Quellauslasses 2, through which the air from within the Quellauslasses 2 to the outside in the interior 4 in the direction of FIG. 2b shown arrows 20 can occur. Above the source outlet 2, a bearing device 9 made of sheet metal is shown, to which the source outlet 2 is fastened. The storage device 9 is disposed within the false ceiling 3 of the interior space 4 and therefore does not claim any additional volume of the interior space 4. The storage device 9 opens on the ceiling side into an opening cross-section 12 defined by the length 10 and width 11 of the storage device 9, which extends in one of the interior ceiling 14 formed level is located. The storage device 9 is followed by a retaining device 15 in the form of a cover formed from two metal flaps 16, 17, which is open in the ventilation state B. At a distance from the side facing away from the interior 4 of the bearing device 9, a distribution channel 13 connects, is introduced into the air from supply pipes, not shown, during the ventilation state and the not shown here but known per se further source outlet 2 is supplied.

Figur 2 a zeigt den Quellauslass 2 in einem Ruhezustand R. In dem Ruhezustand R ist der Quellauslass 2 zusammengefaltet in Lagervorrichtung 9 gelagert. Das Volumen welches der Quellauslass 2 einnimmt, ist um ein Vielfaches geringer als in den übrigen beiden Figuren. Die Klappen 16, 17 der Rückhaltevorrichtung 15 sind in dem Ruhezustand R geschlossen und verdecken den Quellauslass 2 vollständig und halten ihn darüber hinaus davon ab, beschleunigt allein von seiner eigenen Gewichtskraft, durch den Öffnungsquerschnitt 12 in den Innenraum 4 hineinzufallen. FIG. 2 a shows the source outlet 2 in an idle state R. In the rest state R, the source outlet 2 is stored folded in storage device 9. The volume occupied by the Quellauslass 2 is many times less than in the other two figures. The flaps 16, 17 of the restraint device 15 are closed in the rest state R and completely obscure the source outlet 2 and keep it from accelerating solely by its own weight force to fall through the opening cross-section 12 in the interior 4.

Figur 2 b zeigt ein weiteres Mal den auseinander gefalteten, vollständig aufgeblähten Quellauslass 2 in dem Belüftungszustand B. In diesem Zustand befindet sich der Quellauslass 2 innerhalb des Innenraumes 4 und hat die Lagervorrichtung 9 vollständig verlassen. FIG. 2 b shows once again the unfolded, fully inflated source outlet 2 in the ventilation state B. In this state, the source outlet 2 is located inside the interior 4 and has completely left the storage device 9.

Zur Überführung von dem in Figur 2a gezeigten Ruhezustand R in den in Figur 1 und 2b gezeigten Betriebszustand B genügt es, dass zugeführte Luft zu einem Bereich 19 des Quellauslasses gelangt und dadurch ein genügend starker Luftdruck aufgebracht wird, der gleichzeitig den Quellauslass entfaltet und mittels diesem die beiden Klappen 16, 17 nach außen drückt. Im Belüftungszustand wird die endgültige äußere Form des Quellauslasses 2 durch den ihm zugeführten Luftstrom und den Zuschnitt der Quellfläche 8 bestimmt. Im übrigen bewirkt neben dem zugeführten Luftstrom auch das Eigengewicht des Quellauslasses 2 das Öffnen der Klappen 16, 17 der Rückhaltevorrichtung 15, wobei das Eigengewicht allein selbstverständlich nicht genügt, die Klappen 16, 17 zu öffnen.For the transfer of the in FIG. 2a shown rest state R in the in FIG. 1 and 2 B shown operating state B it is sufficient that supplied air reaches an area 19 of the source outlet and thereby a sufficiently strong air pressure is applied, which simultaneously unfolds the source outlet and presses by means of this the two flaps 16, 17 to the outside. In the aeration state, the final outer shape of the source outlet 2 is determined by the air flow supplied to it and the blanking of the source surface 8. Moreover, in addition to the supplied air flow and the weight of the Quellauslasses 2 causes the opening of the flaps 16, 17 of the restraint device 15, the weight alone, of course, is not enough to open the flaps 16, 17.

Die Figur 2b zeigt noch ein Abstandsmittel 18 in Form eines Zuführkanals zur Zuführung von Luft , welches den Quellauslass 2 und die Lagervorrichtung 9 miteinander verbindet. Nicht gezeigt sind besondere Luftzuführöffnungen in Form von Schlitzen, die an der Mantelfläche 5 des Quellauslasses 2 im Bereich 19 des Abstandsmittels 18 angeordnet sind. Die Luftzuführöffnungen ermöglichen die Einleitung eines großen Volumenstromes von Luft über den Zuführkanal in den Quellauslass 2.The FIG. 2b shows still a spacing means 18 in the form of a feed channel for supplying air, which connects the Quellauslass 2 and the storage device 9 together. Not shown are special air supply openings in the form of slots, which are arranged on the lateral surface 5 of the Quellauslasses 2 in the region 19 of the spacer means 18. The air supply openings allow the introduction of a large volume flow of air via the feed channel into the source outlet 2.

Nicht gezeigt ist schließlich auch eine Zuführeinrichtung, insbesondere Wasserleitungen und Düsen, mittels der der Quellauslass 2 im Belüftungszustand besonders schnell und sicher befeuchtbar ist.Finally, not shown is also a feed device, in particular water lines and nozzles, by means of which the source outlet 2 in the ventilation state can be humidified particularly quickly and safely.
