Abstract

The proposal is for an air supply device in which the air to be supplied to a room flows through facing, open, trough-shaped sections (26, 28) arranged in rows.

Description

Die Erfindung bezieht sich auf eine Luftzuführungseinrichtung.The invention relates to an air supply device.

Übliche Luftzuführungseinrichtungen weisen am Ende von z.B. einem Luftschacht z.B. ein Lochblech oder Drahtgitter auf, durch das Frischluft einem Raum zugeführt wird. Um insbesondere Zugerscheinungen zu vermeiden, sollte die ausströmende Luft eine maximale Geschwindigkeit von 0,6 m/sec, vorzugsweise jedoch von 0,1 - 0,2 m/sec haben. Hierdurch ist jedoch häufig nicht der gewünschte Luftmengendurchsatz mit nur wenigen Lochblechen möglich, so daß infolgedessen an mehreren Stellen eines Raumes entsprechende Zuluftöffungen vorgesehen werden müssen. Dies kann zu bautechnischen Schwierigkeiten führen. Auch wirken die die Öffnungen bildenden Lochbleche oder Gitter optisch störend. Schließlich kann beim Einsatz in z.B. gewerblichen Räumen wie z.B. Küchen der Nachteil auftreten, daß durch das Lochblech Spritzwasser in den Luftschacht gelangt, so daß infolgedessen die Gefahr von unkontrollierten Bakterienherden erwächst.Conventional air supply devices have, for example, a perforated plate or wire mesh at the end of, for example, an air duct, through which fresh air is supplied to a room. In order to avoid drafts in particular, the outflowing air should be a have a maximum speed of 0.6 m / sec, but preferably of 0.1-0.2 m / sec. As a result, however, the desired air flow rate is often not possible with only a few perforated plates, so that corresponding supply air openings must consequently be provided at several points in a room. This can lead to structural difficulties. The perforated sheets or grids forming the openings also have an optically disruptive effect. Finally, when used in, for example, commercial rooms such as kitchens, the disadvantage may arise that splashed water gets into the air shaft through the perforated plate, so that the risk of uncontrolled bacterial sources increases as a result.

Aus der EP-A 0 337 971 ist eine Luftzuführungseinrichtung der eingangs genannten Art bekannt, die aus unterschiedlich aufgebauten inneren und äußeren Elemente besteht, von denen die inneren Elemente in Reihen angeordnete Öffnungen aufweisen, die in das Innere der Luftzuführungseinrichtung ragende Begrenzungswandungen aufweisen.EP-A 0 337 971 discloses an air supply device of the type mentioned at the outset, which consists of differently constructed inner and outer elements, of which the inner elements have openings arranged in rows and have boundary walls projecting into the interior of the air supply device.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde eine entsprechende Luftzuführungseinrichtung derart weiterzubilden, daß diese konstruktiv einfach aufgebaut ist, wodurch gleichzeitig die Möglichkeit geschaffen werden soll, Gehäuseabschnitte gewünschter Abmessungen problemlos zur Verfügung zu stellen. Auch soll die Luftverteilung über die Fläche mit einfachen Mitteln regulierbar sein.The present invention is based on the object of developing a corresponding air supply device in such a way that it is of simple construction, which at the same time is intended to make it possible to provide housing sections of desired dimensions without problems. The air distribution over the surface should also be adjustable with simple means.

Die Aufgabe wird gelöst durch eine Luftzuführungseinrichtung mit zumindest vorzugsweise im Bodenbereich eines Raumes vorhandenen und Öffnungen aufweisenden Elementen, über die aus der Luftzuführungseinrichtung für den Raum bestimmte Zuluft strömt, wobei die Elemente zumindest in zwei gegenüberliegenden Reihen angeordnete, zumindest abschnittsweise im Querschnitt offene, rinnenförmige erste und zweite Profilteile umfassen, die zur Bildung der für die Zufluft bestimmten Öffnungen zumindest bereichsweise zueinander beabstandet sind, und wobei die ersten und zweiten Profilteile mit ihren offenen Seiten einander zugewandt angeordnet sind derart, daß die Öffnungen zwischen den ersten Profilteilen von den zweiten Profilteilen abgedeckt sind.The task is solved by an air supply device with at least preferably in the floor area of a room and having elements through which certain air flows from the air supply device for the room, the elements arranged at least in two opposite rows, at least partially open in cross-section, channel-shaped first and second profile parts comprise, which are at least partially spaced from one another to form the openings intended for the supply air, and wherein the first and second profile parts are arranged with their open sides facing one another such that the openings between the first profile parts are covered by the second profile parts.

Insbesondere zeichnet sich die Erfindung dadurch aus, daß sich die Profilteile der einen Reihe zumindest abschnittsweise in die der zweiten Reihe erstrecken. Hierdurch erfolgt ein Ineinandergreifen, wodurch die Zuluft nicht nur durch die Profilteile umgelenkt wird, sondern es erfolgt auch aufgrund der durch das Ineinandergreifen bedingten Kammerbildung eine Beeinflussung der Strömungsgeschwindigkeit. Hierdurch kann überraschenderweise der Zuluftmengendurchsatz erhöht werden, so daß Austrittsgeschwindigkeiten der Größenordnung von mehr als 0,5 m/sec hingenommen werden könnten, ohne daß für in dem Raum befindliche Personen unangenehme Zugerscheinungen spürbar werden.In particular, the invention is characterized in that the profile parts of one row extend at least in sections into that of the second row. This results in an interlocking, whereby the supply air is not only diverted by the profile parts, but there is also an influence on the flow rate due to the interlocking chamber formation. As a result, the supply air throughput can surprisingly be increased, so that outlet speeds of the order of magnitude of more than 0.5 m / sec could be accepted without unpleasant side effects being felt by people in the room.

Durch das Umlenken und abwechselnde Beschleunigen bzw. Beruhigen der Zuluft während des Durchströmens der Profilteile erfährt die austretende Luft außerdem eine diffuse Verteilung, wodurch der ansonsten störend wirkende gerichtete Luftstrahl, der bei Lochblechen oder Gittern auftritt, vermieden wird.By deflecting and alternately accelerating or calming the supply air while flowing through the profile parts, the escaping air also experiences a diffuse distribution, which avoids the otherwise disruptive directional air jet that occurs with perforated sheets or grilles.

Man kann sogar von einer pulsierend zugeführten Zuluft sprechen, die bei mit Draht- oder Lochblechauslässen versehenen Luftzuführungseinrichtungen nicht erzielbar sind.One can even speak of a pulsating supply air which cannot be achieved with air supply devices provided with wire or perforated plate outlets.

Durch die mit den offenen Seiten einander zugewandten und vorzugsweise ineinandergreifenden Profilteile wird außerdem der Vorteil erreicht, daß gegebenenfalls in der Zuluft noch vorhandene Schmutzpartikel während des Verwirbelns innerhalb der und zwischen den Profilteilen abgeschieden werden, so daß die Zuluft einen hohen Reinheitsgrad aufweist.The mutually facing and preferably interlocking profile parts also have the advantage that any dirt particles still present in the supply air are separated during swirling within and between the profile parts, so that the supply air has a high degree of purity.

Eine besonders günstige Zuluftzuführung ergibt sich dann, wenn das Profilteil einen vom Scheitelbereich der Innenfläche ausgehenden, sich in Richtung der Profilteilöffnung und entlang seiner Längsachse verlaufenden Vorsprung aufweist, der zu einer weiteren Kammerbildung im Bereich des Profilteils selbst bzw. in bezug auf die eingreifenden Ränder der zugeordneten benachbarten Profilteile der gegenüberliegenden Reihe führt.A particularly favorable supply air supply is obtained if the profile part has a protrusion starting from the apex region of the inner surface and extending in the direction of the profile part opening and along its longitudinal axis, which leads to a further chamber formation in the region of the profile part itself or in relation to the engaging edges of the assigned adjacent profile parts of the opposite row leads.

Hierdurch wird erkennbar die Strömungsgeschwindigkeit bzw. die Verwirbelung der dem Raum zuzuführenden Luft zusätzlich beeinflußt.As a result, the flow velocity or the swirling of the air to be supplied to the room is additionally influenced.

Die Profilteile selbst können im Schnitt bogenförmig, V-förmig oder U-förmig ausgebildet sein. Bevorzugt ist jedoch eine Bogenform mit einem Öffnungswinkel kleiner als 180°.The profile parts themselves can be arcuate, V-shaped or U-shaped in section. However, an arc shape with an opening angle of less than 180 ° is preferred.

Die die Profilteile aufweisenden Elemente können in Ausgestaltung der Erfindung im Bodenbereich einer Verkleidung angeordnet sein, die z.B. beabstandet ein konstruktiv bedingtes Säulenelement umgeben kann.In an embodiment of the invention, the elements having the profile parts can be arranged in the base region of a cladding which, for example, spaced around a design-related column element can surround.

Schließlich wird durch die erfindungsgemäße Lehre ein architektonisches Gestaltungselement zur Verfügung gestellt, das durch die Profilteile überaus ansprechend wirkt, da die zu Flächen zusammengesetzten rinnenförmigen Elemente optisch geschlossen wirken.Finally, the teaching according to the invention provides an architectural design element which has an extremely appealing effect due to the profile parts, since the channel-shaped elements which are put together to form surfaces appear optically closed.

Um einem Raum kontrolliert Zuluft zuzuführen, können die von den Profilteilen zur Verfügung gestellten Zuluftkanäle im gewünschten Umfang angeordnet werden, wobei zwischen einzelnen Profilteilen Blindabdeckungen vorgesehen sein können, die ein Durchströmen von Zuluft verhindern. Dadurch erzielt man zusätzlich eine Reguliermöglichkeit hinsichtlich der Luftdurchsatzmenge und deren Austrittsgeschwindigkeiten.In order to supply fresh air to a room in a controlled manner, the supply air ducts provided by the profile parts can be arranged to the desired extent, blank covers being provided between individual profile parts, which prevent supply air from flowing through. This also provides a means of regulating the air flow rate and its outlet speeds.

Vorzugsweise sind die Längsachsen der Profilteile vertikal angeordnet, so daß gegebenenfalls in diesen zurückgehaltene Partikel schwerkraftbedingt in den Bodenbereich des Elementes gelangen, wo sie z.B. in einer Sammelwanne aufgefangen und entfernt werden können.The longitudinal axes of the profile parts are preferably arranged vertically, so that, if necessary, particles retained in them reach the bottom region of the element due to gravity, where they can be collected and removed, for example, in a collecting trough.

Eine Ausgestaltung sieht vor, daß der Zwischenraum von Profilteilen einer Reihe zumindest abschnittsweise verschlossen ist. Insbesondere ist vorgesehen, daß der Zwischenraum durch zumindest eine entfernbare Abdeckung verschlossen ist. Dabei kann die Abdeckung eine Doppelfunktion ausüben, nämlich zum einen Luftzuführungsschlitze oder -kanäle zumindest abschnittsweise verschließen und zum anderen als Halterung für innenliegende Profilteile dienen.One embodiment provides that the space between profile parts of a row is closed at least in sections. In particular, it is provided that the space is separated by at least one removable cover is closed. The cover can perform a double function, namely, on the one hand, closing air supply slots or ducts at least in sections and, on the other hand, serving as a holder for internal profile parts.

Die Abdeckungen können aus Metall, Gummi, Kunststoff o.ä. bestehen. Sie sind entfernbar ausgebildet und können quasi als "Normteil" an jeder gewünschten Stelle einer Luftzuführungseinrichtung zwischen Profilteile "geklemmt" werden. Auch ein Aneinanderreihen von Abdeckungen ist möglich.The covers can be made of metal, rubber, plastic or the like. consist. They are designed to be removable and can be "clamped" as a "standard part" at any desired location of an air supply device between profile parts. It is also possible to string covers together.

Durch die Abdeckungen wird einerseits die Funktion der Profilteile in bezug auf das Befestigen und Lösen nicht beeinflußt, andererseits jedoch mit einfachen Maßnahmen eine Einstellung einer gleichmäßigen Geschwindigkeitsverteilung über die Höhe der Luftzuführungseinrichtung ermöglicht.On the one hand, the covers do not influence the function of the profile parts with regard to fastening and loosening, but on the other hand, simple measures make it possible to set a uniform speed distribution over the height of the air supply device.

Weitere Einzelheiten, Vorteile und Merkmale der Erfindung ergeben sich nicht nur aus den Ansprüchen, den diesen zu entnehmenden Merkmalen -für sich und/oder in Kombination-, sondern auch aus der nachfolgenden Beschreibung von in der Zeichnung dargestellten bevorzugten Ausführungsbeispielen.Further details, advantages and features of the invention result not only from the claims, the features to be extracted from them - individually and / or in combination - but also from the following description of preferred exemplary embodiments shown in the drawing.

In den Figuren, in denen gleiche Elemente mit gleichen Bezugszeichen versehen sind, sind Luftzuführungseinrichtungen dargestellt, um einen Raum mit Frischluft zu versorgen.In the figures, in which the same elements are provided with the same reference numerals, air supply devices are shown in order to supply fresh air to a room.

In Fig. 1 ist beispielhaft ein Ausschnitt einer gewerblichen Küche (10) dargestellt, die deckenseitig mit einer Flächenentlüftung (12) versehen ist, über die aus dem Küchenraum aufsteigende Luft abgesaugt und dabei gleichzeitig gereinigt wird.In Fig. 1, a section of a commercial kitchen (10) is shown as an example is provided on the ceiling with a surface ventilation (12), through which air rising from the kitchen is sucked out and cleaned at the same time.

Aus dem zwischen der Flächenentlüftung (12) und der zu dieser beabstandeten tragenden Decke (14) vorhandenen Deckenzwischenraum (16) wird zumindest ein Teil der Abluft über einen zum Boden (18) des Raums (10) führenden Zuluftschacht oder -kanal (20) in den Raum (10) zurückgeführt, und zwar über Zuluftöffnungen zur Verfügung stellende Elemente (22) und (24), die beispielsweise in gegenüberliegenden Wandungen des Zuluftschachtes bzw. -kanals (20) vorhanden sind. Die Elemente (22) und (24) sind dabei im Bereich des Bodens (18) angeordnet. Selbstverständlich können auch mehr als die in der Fig. 2 gezeichneten Elemente (22) und (24) oder auch nur ein Element vorgesehen sein. Auch kann eine andere Querschnittsgeometrie vorliegen.At least part of the exhaust air is discharged from the ceiling space (16) between the surface ventilation (12) and the supporting ceiling (14) spaced apart from it via a supply air shaft or duct (20) leading to the floor (18) of the room (10) the room (10) is recirculated, specifically via elements (22) and (24) which provide air supply openings and which are present, for example, in opposite walls of the air supply duct or duct (20). The elements (22) and (24) are arranged in the region of the bottom (18). Of course, more than the elements (22) and (24) shown in FIG. 2 or only one element can also be provided. Another cross-sectional geometry can also be present.

Die Elemente (22) und (24) weisen ineinandergreifende rinnenförmige Profilelemente oder -teile (26) und (28) auf, wodurch die durch den Schacht bzw. Kanal (20) geführte Luft beim Durchströmen der ineinandergreifenden Profilelemente (26) und (28) nicht nurverwirbelt wird, sondern auch eine Beeinflussung in der Strömungsgeschwindigkeit erfährt. Hierdurch ergibt sich der Vorteil, daß die über die Elemente (22) und (24) austretende Zuluft eine höhere Austrittsgeschwindigkeit (bis zu 0,6 m/sec) aufweisen kann, ohne daß es in dem Raum selbst zu störenden Zugerscheinungen oder ähnlichem kommt.The elements (22) and (24) have interlocking trough-shaped profile elements or parts (26) and (28), as a result of which the air passed through the shaft or channel (20) when flowing through the interlocking profile elements (26) and (28) is not only swirled, but also experiences an influence in the flow velocity. This results in the advantage that the supply air exiting via the elements (22) and (24) can have a higher exit speed (up to 0.6 m / sec) without disturbing drafts or the like occurring in the room itself.

Die rinnenförmigen Profilteile (26) und (28), die in Fig. 8, 16, 17, 20 und 22 noch einmal vergrößert dargestellt sind, sind erkennbar in gegenüberliegenden Reihen (30) und (32) angeordnet. Die freien Ränder (34) und (36) der ersten und zweiten Profilteile (26) bzw. (28) überlappen sich, so daß sich zwischen diesen Kammern (38) ausbilden.The trough-shaped profile parts (26) and (28), which are shown enlarged again in FIGS. 8, 16, 17, 20 and 22, are clearly arranged in opposite rows (30) and (32). The free edges (34) and (36) of the first and second profile parts (26) and (28) overlap, so that between these chambers (38) form.

Ferner gehen von den Scheitelpunkten der Innenflächen und in Längsrichtung der Profilteile (26) und (28) verlaufende Vorsprünge (40) und (42) aus, wodurch weitere Kammern gebildet werden, die erkennbar die die Elemente (22) bzw. (24) durchströmende Luft beeinflussen.Furthermore, protrusions (40) and (42) extend from the apexes of the inner surfaces and in the longitudinal direction of the profile parts (26) and (28), as a result of which further chambers are formed which recognizably flow through the elements (22) and (24) Affect air.

Die vorzugsweise ineinandergreifenden Profilteile (26) und (28) und die von diesen ausgehenden inneren Vorsprünge (40) und (42) bewirken jedoch nicht nur eine Beeinflussung der über den Kanal bzw. Schacht (20) zugeführten Zuluft, sondern stellen gleichzeitig sicher, daß in den Kanal über die zueinander beabstandet angeordneten Profilteile (26) und (28) kein Spritzwasser in das Innere des Schachtes bzw. des Kanals (20) dringen kann.However, the preferably interlocking profile parts (26) and (28) and the inner projections (40) and (42) emanating from them not only influence the supply air supplied via the duct or duct (20), but also ensure that No splash water can penetrate into the channel via the spaced-apart profile parts (26) and (28) into the interior of the shaft or channel (20).

Neben diesen technischen Vorteilen ergibt sich des weiteren ein ästhetischer, da die Profilteile das Erscheinungsbild einer geschlossenen Fläche zeigen, die gestalterisch, z.B. farblich individuellen Anforderungen angepaßt werden kann.In addition to these technical advantages, there is also an aesthetic one, since the profile parts show the appearance of a closed surface, which in terms of design, e.g. color can be adapted to individual requirements.

Bei dem Ausführungsbeispiel der Fig. 3 und 4 wird aus einem Zwischenraum (16) Luft auch mit Außenluft gemischt und über in Seitenwandungen (46), (48), (50) einer eine Säule (52) umgebenden Verkleidung (54) an den Raum (56) abgegeben. Dabei zeigt die Schnittdarstellung gemäß Fig. 4, daß die Profilteile über die Wandungen (44), (46), (48) und (50) nicht gleichmäßig verteilt sind, wodurch der Vorteil erzielbar ist, daß die Menge der dem Raum (56) zuzuführenden Zuluft in verschiedenen Richtungen unterschiedlich sein kann.In the embodiment of FIGS. 3 and 4, air is also mixed with outside air from an intermediate space (16) and is passed into the side walls (46), (48), (50) of a cladding (54) surrounding a column (52) (56) submitted. 4 shows that the profile parts are not evenly distributed over the walls (44), (46), (48) and (50), whereby the advantage can be achieved that the amount of space (56) Supply air to be supplied can be different in different directions.

In den Bereichen, wo die Zuluft die ineinandergreifenden Profilteile (26) und (28) nicht durchströmen soll, sind Blindabdeckungen vorgesehen, die beispielhaft mit den Bezugszeichen (58) und (60) bezeichnet sind. Eine entsprechende Blindabdeckung (59) ist auch in Fig. 22 dargestellt. Man erkennt bei den Blindabdeckungen (59) in den Längsrandbereichen gleichfalls Vorsprünge (42), die zum Festlegen der Blindabdeckung in Halterungen dienen, die anhand der Fig. 12 und 13 beispielhaft erläutert werden.In the areas where the supply air should not flow through the interlocking profile parts (26) and (28), blind covers are provided, which are used, for example, with the Reference numerals (58) and (60) are designated. A corresponding blind cover (59) is also shown in FIG. 22. The blind covers (59) in the longitudinal edge regions also show projections (42) which are used to fix the blind cover in brackets, which are explained by way of example with reference to FIGS. 12 and 13.

Auch unterscheidet sich das Ausführungsbeispiel der Fig. 3 und 4 von dem der Fig. 1 und 2 dahingehend, daß quasi über die gesamte Länge der Verkleidung (54) Zuluft an den Raum (56) abgegeben wird.The embodiment of FIGS. 3 and 4 also differs from that of FIGS. 1 and 2 in that supply air is emitted to the room (56) over the entire length of the covering (54).

Die Fig. 7a und 7b sollen detaillierter verdeutlichen, daß zwischen den ineinandergreifenden Profilteilen (26) und (28) im gewünschten Umfang größere Flächen abgedeckt werden können, durch die ein Durchtritt von Zuluft verhindert wird, um also auf diese Weise die Zuluft kontrolliert gerichtet in den jeweiligen Raumbereich leiten zu können.7a and 7b are intended to clarify in more detail that between the interlocking profile parts (26) and (28) larger areas can be covered to the desired extent, through which a passage of supply air is prevented, so that in this way the supply air is directed in a controlled manner to be able to manage the respective room area.

Die Luftzuführungseinrichtung nach dem Ausführungsbeispiel der Fig. 5 und 6 stellt eine Eckverkleidung (62) dar, die bodenseitig das die Luftzuführungsöffnungen umfassende Element (64) aufweist, durch die ineinandergreifenden Profilteile (26) und (28) gebildet werden. Selbstverständlich kann sich das Element (64) auch über die gesamte Länge der Eckverkleidung (62) erstrecken, die wandinnenseitig von dem Deckenzwischenraum (16) mit Zuluft beaufschlagt wird. Andere Ausführungsformen und Möglichkeiten sind gleichfalls möglich.The air supply device according to the exemplary embodiment of FIGS. 5 and 6 represents a corner cladding (62) which on the bottom side has the element (64) comprising the air supply openings, by means of which interlocking profile parts (26) and (28) are formed. Of course, the element (64) can also extend over the entire length of the corner cladding (62) which is supplied with supply air from the ceiling space (16) on the inside of the wall. Other embodiments and possibilities are also possible.

Die ineinandergreifenden in den Reihen (30) und (32) angeordneten rinnenförmigen Profilteile (26) und (28) sind in der Fig. 8 noch einmal detailliert dargestellt, wobei gleichzeitig die von den Scheitelbereichen der Innenflächen ausgehenden und sich in Richtung der jeweiligen Öffnung erstreckenden inneren Vorsprünge (40) und (42) klar ersichtlich werden.The interlocking trough-shaped profile parts (26) and (28) arranged in the rows (30) and (32) are shown again in detail in FIG. 8, wherein at the same time those extending from the apex regions of the inner surfaces and extending in the direction of the respective opening inner protrusions (40) and (42) clear become apparent.

Ist zwar die Bogenform der Profilteile (26) und (28) als bevorzugt anzugeben, wobei der Öffnungswinkel kleiner als 180° sein sollte, so verdeutlichen die Fig. 9 bis 11, daß auch andere Gestaltungen der die Luftzuführungsöffnungen bildenden Profilteile möglich sind.If the arc shape of the profile parts (26) and (28) is to be given as preferred, the opening angle being smaller than 180 °, FIGS. 9 to 11 illustrate that other designs of the profile parts forming the air supply openings are also possible.

Das Profilteil (66) nach Fig. 9 ist im Querschnitt V-förmig, wobei die Ränder (68) und (70) der einander zugewandten Profilteile parallel zueinander verlaufen können.The profile part (66) according to FIG. 9 is V-shaped in cross-section, the edges (68) and (70) of the profile parts facing one another being able to run parallel to one another.

In bezug auf die Innenvorsprünge sind gleichfalls unterschiedliche Geometrien möglich. Ist -wie bei den Profilteilen (26) und (28)- im Schnitt eine knaufförmige Erweiterung als bevorzugt anzusehen, so können die freien Endbereiche jedoch auch eine Rechteckform (Vorsprung 72), eine Kreisform (Vorsprung 74) oder eine Tropfenform (Vorsprung 76) zeigen. Die vorderen, die zuvor beschriebenen Geometrien aufweisenden Enden sind dabei über einen Steg mit den Innenflächen des jeweiligen Profilteils (66) verbunden.Different geometries are also possible with regard to the inner projections. If, as with the profile parts (26) and (28), a knob-shaped extension is to be regarded as preferred on average, the free end regions can also have a rectangular shape (projection 72), a circular shape (projection 74) or a teardrop shape (projection 76). demonstrate. The front ends, which have the geometries described above, are connected to the inner surfaces of the respective profile part (66) via a web.

Die Möglichkeit, Profilteile in Art einer offenen Rechteckform zu verwenden, soll durch die Fig. 10 und 11 verdeutlicht werden. So weisen die Profilteile (78) der Fig. 10 eine U-Form auf, wobei die freien Enden (80) und (82) der Seitenschenkel (84) und (86) einander zugewandt sind. Hierdurch ergibt sich gleichfalls eine Kammerbildung von zwei ineinandergreifenden Profilteilen (78). Der innere Vorsprung (88) des Profilteils (78) weist eine T-Form auf.The possibility of using profile parts in the manner of an open rectangular shape is intended to be illustrated by FIGS. 10 and 11. 10 has a U-shape, the free ends (80) and (82) of the side legs (84) and (86) facing each other. This also results in a chamber formation of two interlocking profile parts (78). The inner projection (88) of the profile part (78) has a T-shape.

Das der Fig. 11 zu entnehmende Profilteil (90) zeigt eine reine kantige U-Form, wobei die inneren Vorsprünge unterschiedliche Geometrien zeigen können. So kann neben einem einfachen parallel zu den Seitenschenkeln verlaufenden Steg (Vorsprung 96) auch eine Form gewählt werden, bei der der Steg im Schnitt eine kreisförmige (Bezugszeichen 94) bzw, rhombusartige (Bezugszeichen 92) Geometrie besitzen kann.The profile part (90) shown in FIG. 11 shows a pure angular U-shape, the inner projections being able to show different geometries. Thus, in addition to a simple web (projection 96) running parallel to the side legs a shape can be selected in which the cross-section of the web can have a circular (reference number 94) or rhombus-like (reference number 92) geometry.

Den Fig. 12 bis 14 sind Halterungen (230) zur Aufnahme von Profilteilen wie denen mit dem Bezugszeichen (26) und (28) versehenen zu entnehmen. Man erkennt, daß von einem Basiselement (232) bzw. (242) abgewinkelte Schenkel (234), (236), (238), (240) ausgehen, die paarweise einander zugeordnet sind. So sind die Schenkel (234) und (236) derart zueinander ausgerichtet, daß ein rinnenförmiges Profilteil (26), das mit seiner Öffnung dem mit der Zuluft zu beschickenden Raum zugewandt ist, außenseitig teilweise umgriffen und damit festgehalten wird. Die weiteren Schenkel (238) und (240) des Basiselementes (232) und der Schenkel (244) des Basiselementes (242) dienen dazu, die Vorsprünge (42) der Profilteile (28) zu erfassen, also derjenigen, deren Außenflächen dem jeweiligen Raum zugewandt sind, die also vom Raum aus sichtbar sind.12 to 14, brackets (230) for receiving profile parts such as those provided with the reference numerals (26) and (28) can be seen. It can be seen that angled legs (234), (236), (238), (240) emanate from a base element (232) or (242) and are assigned to one another in pairs. Thus, the legs (234) and (236) are aligned with one another in such a way that a channel-shaped profile part (26), which with its opening faces the space to be supplied with the supply air, is partially encompassed on the outside and is thus held in place. The further legs (238) and (240) of the base element (232) and the legs (244) of the base element (242) serve to capture the projections (42) of the profile parts (28), that is to say those whose outer surfaces correspond to the respective space are facing, so they are visible from the room.

Um die Vorsprünge (42) sicher zu erfassen, weisen die Endbereiche (258) und (260) der Schenkel (240) und (238) dergestalt sich ergänzende Geometrien auf, daß das vorzugsweise im Schnitt tropfen- oder knaufartig ausgebildete Ende des Vorsprungs (42) weitgehend formschlüssig erfaßt wird.In order to securely grasp the projections (42), the end regions (258) and (260) of the legs (240) and (238) have complementary geometries in such a way that the end of the projection (42 ) is recorded in a largely positive manner.

Die Basiselemente (232) und (242) mit den abragenden Schenkeln (234), (236), (238) und (240) werden sodann in Aufnahmeschienen (246) aneinandergereiht, um so die Profilteile vorzugsweise in ihren Stirnbereichen lösbar und in eindeutiger Ausrichtung zueinander aufzunehmen.The base elements (232) and (242) with the projecting legs (234), (236), (238) and (240) are then strung together in mounting rails (246), so that the profile parts are preferably detachable in their end regions and in a clear orientation to record each other.

In Fig. 14 ist eine bevorzugte Ausführungsform einer Aufnahmeschiene (244) dargestellt, die als Hohlprofil ausgebildet und über Vorsprünge (245) und (247), die von den Seitenrändern ausgehen, in Eck- oder Randstücken von Luftzuführungseinrichtungen einrastbar ist, die beispielhaft in den Fig. 19 a-b dargestellt sind. In einer schwalbenschwanzförmig gebildeten Aufnahme (249) sind dann die flächigen Basiselemente einbringbar und verschiebbar.In Fig. 14 a preferred embodiment of a receiving rail (244) is shown, which is designed as a hollow profile and over projections (245) and (247) by the Extend side edges, can be snapped into corner or edge pieces of air supply devices, which are shown as an example in Fig. 19 from. The flat base elements can then be introduced and displaced in a dovetail-shaped receptacle (249).

Dadurch, daß die in Reihen angeordneten Schenkel, auf der einen Seite die Schenkel (234) und (236), auf der anderen Seite die Schenkel (238) und (240), stets nur Profilteilen einer Reihe, also der Reihe (30) bzw. der Reihe (32) zugeordnet sind, wird erkennbar, daß ein überaus problemloses Montieren bzw. Entfernen der Profilteile (28) bzw. (26) möglich ist. So bedarf es nur eines Ziehens der jeweiligen Profilteile senkrecht zu den Ebenen, die von den Reihen (30) bzw. (32) der ersten und zweiten Profilteile (26) bzw. (28) aufgespannt sind, von den Halterungen weg, um z.B. Profilteile auszutauschen oder Wartungsarbeiten am Zuluftschacht o.ä. durchzuführen.Because the legs arranged in rows, on one side the legs (234) and (236), on the other side the legs (238) and (240), always only profile parts of a row, i.e. the row (30) or . The row (32) are assigned, it can be seen that an extremely easy assembly or removal of the profile parts (28) or (26) is possible. It is therefore only necessary to pull the respective profile parts perpendicular to the planes, which are spanned by the rows (30) and (32) of the first and second profile parts (26) and (28), away from the holders, in order to e.g. Exchanging profile parts or maintenance work on the supply air shaft or similar. perform.

In den Fig. 15 und 16 sind weitere hervorzuhebende Merkmale von Luftzuführungseinrichtungen dargestellt, die vom grundsätzlichen Aufbau den zuvor beschriebenen entsprechen. Folglich greifen rinnenförmig ausgebildete Profilteile (26) und (28) ineinander ein, wobei von den Profilteilen (26) und (28) Innenvorsprünge (40) und (42) ausgehen.15 and 16 show further features of air supply devices which are to be emphasized and which correspond in principle to those described above in terms of their basic structure. As a result, trough-shaped profile parts (26) and (28) engage in one another, internal projections (40) and (42) starting from the profile parts (26) and (28).

Um zu erreichen, daß z.B. nur im Bodenbereich einer Luftzuführungseinrichtung Zuluft in einen Raum einströmt, gleichwenn die Luftzuführungseinrichtung Profilteile (26) und (28) aufweist, die z. B. auch im mittleren oder oberen Bereich eines Raumes verlaufen, ist vorgesehen, daß die zwischen den Profilteilen (26) und (28) ausgebildeten Zuluftkanäle zumindest abschnittsweise abgedeckt werden können.In order to achieve that, for example, supply air flows into a room only in the floor area of an air supply device, even if the air supply device has profile parts (26) and (28) which, for. B. also run in the middle or upper area of a room, it is provided that the supply air ducts formed between the profile parts (26) and (28) can be covered at least in sections.

Hierzu werden beispielhaft die von außen sichtbaren Kanäle (100) mit Abdeckungen (102) und (103) verschlossen, die sich nicht notwendigerweise über die gesamte Länge der ineinandergreifenden Profilelemente (26) und (28) erstrecken müssen. Diese Abdeckungen (102) und (103) werden folglich zwischen aneinandergrenzenden Abschnitten (104) und (106) von außenliegenden Profilteilen festgelegt, wobei die nach außen gerichteten inneren Vorsprünge (40) der Profilteile (26) von den Abdeckungen erfaßt werden. Die Abdeckungen (102) und (103) können hierdurch eine Doppelfunktion ausüben. So dienen sie zum einen zum Sperren von Luftaustrittskanälen (100) und zum anderen zum Festlegen von Profilteilen (26). Andererseits können die Vorsprünge (40) selbst Halterungen für die Abdeckungen (102) sein.For this purpose, the channels (100) visible from the outside are closed with covers (102) and (103), which do not necessarily have to extend over the entire length of the interlocking profile elements (26) and (28). These covers (102) and (103) are consequently fixed between adjoining sections (104) and (106) of outer profile parts, the outwardly directed inner projections (40) of the profile parts (26) being gripped by the covers. The covers (102) and (103) can thus perform a double function. So they serve on the one hand to block air outlet channels (100) and on the other hand to fix profile parts (26). On the other hand, the projections (40) themselves can be holders for the covers (102).

Sofern die Abdeckungen (103) Halterungen für Profilteile (26) bzw. (28) sein sollen, müssen erstere die Außenflächen der zu haltenden Profilteile über deren größten Durchmesser hinaus erfassen.If the covers (103) are to be holders for profile parts (26) or (28), the former must grasp the outer surfaces of the profile parts to be held beyond their largest diameter.

Die Abdeckungen können aus unterschiedlichen Materialien wie z.B. Metall, aber auch aus Gummi oder Kunststoff bestehen. Auch können sie farblich gestaltet oder strukturiert sein, um zusätzlich das äußere Erscheinungsbild der erfindungsgemäßen Luftzuführungseinrichtung zu gestalten.The covers can be made of different materials such as Metal, but also made of rubber or plastic. They can also be colored or structured in order to additionally design the external appearance of the air supply device according to the invention.

In Fig. 17 ist ein Ausschnitt einer Luftzuführungseinrichtung, und zwar eines Eckbereiches dargestellt. Die einem Raum zuzuführende Luft strömt über zumindest zwei Flächen (262) und (264), die im Ausführungsbeispiel einen rechten Winkel zueinander beschreiben. Andere Anordnungen sind gleichfalls möglich. In jeder Fläche (262) und (264) sind im gewünschten Umfang ineinandergreifende Profilelemente (26) und (28) angeordnet, die Innenvorsprünge (42) aufweisen können. Bereiche der Flächen (262) und (264) können durch Abdeckungen verschlossen sein, wie sie in Fig. 23 mit dem Bezugszeichen (59) versehen sind. Auch können Durchtrittsöffnungen, von denen zwei beispielhaft mit dem Bezugszeichen (266) oder (268) versehen sind, mit Abdeckungen verschlossen sein, wie sie anhand der Fig. 15 und 16 beschrieben worden sind bzw. anhand der Fig. 20 und 21 beschrieben werden.17 shows a section of an air supply device, specifically a corner area. The air to be supplied to a room flows over at least two surfaces (262) and (264), which in the exemplary embodiment describe a right angle to one another. Other arrangements are also possible. In each surface (262) and (264) interlocking profile elements (26) and (28) are arranged to the desired extent, which can have inner projections (42). Areas of the surfaces (262) and (264) can be closed by covers as they are provided with the reference symbol (59) in FIG. 23. Through openings, two of which are provided with the reference number (266) or (268) by way of example, can be closed with covers, as described with reference to FIGS. 15 and 16 or described with reference to FIGS. 20 and 21.

Um die Halterungen gemäß der Fig. 12 bis 14 zu zeigen, sind bei der Fläche (264) die Profilelemente weggelassen. Man erkennt die als Hohlprofil ausgebildete Aufnahmeschiene (244), auf der aufeinanderreihbar die Halteelemente für die Profile (26), (28) angeordnet sind. Die Schiene (Hohlprofil (244)) wird zwischen Schenkeln (245) und (247) festgelegt, die ihrerseits in Aufnahmen (266) eines Eckstücks (268) verrastbar eingreifen, welches die Flächen (262) und (264) verbindet.In order to show the brackets according to FIGS. 12 to 14, the profile elements are omitted from the surface (264). One recognizes the receiving rail (244) designed as a hollow profile, on which the holding elements for the profiles (26), (28) are arranged in a row. The rail (hollow profile (244)) is fixed between legs (245) and (247), which in turn engage in receptacles (266) of a corner piece (268) which connects the surfaces (262) and (264).

Das Eckstück (268), das ein stranggepreßtes Profil ist, weist eine Basisfläche (270) auf, von der die Aufnahmen (266) aufweisenden Schenkel (272) und (274) ausgehen, die parallel zu den Flächen (262) bzw. (264) verlaufen. Die Enden der Schenkel (262) und (264) weisen einen bogenförmigen Verlauf (Abschnitte (276) und (278)) auf, der gleich den entsprechenden Abschnitten der Profilelemente (26) und (28) ist. Die Abschnitte (276) und (278) greifen folglich in angrenzende Profilelemente (26), um auf diese Weise die gewünschte Kammerausbildung auch im Randbereich der Flächen (262) und (264) zur Verfügung zu stellen.The corner piece (268), which is an extruded profile, has a base surface (270), from which the receptacles (266) have legs (272) and (274) that extend parallel to the surfaces (262) and (264 ) run. The ends of the legs (262) and (264) have an arcuate course (sections (276) and (278)) which is identical to the corresponding sections of the profile elements (26) and (28). Sections (276) and (278) consequently engage in adjacent profile elements (26) in order in this way to provide the desired chamber formation also in the edge region of surfaces (262) and (264).

Die Schnittdarstellung in Fig. 23 soll noch einmal die Geormetrie der Aufnahmeschiene (244) verdeutlichen. Man erkennt die schwalbenschwanzförmige Aufnahme (249) für die Halteelemente (234), (236), (238) und (240) und die auf der gegenüberliegenden Seite verlaufenden Vorsprünge (245) und (247), die in die Aufnahmen (266) der Eckstücke (268) einrasten.The sectional view in FIG. 23 is intended once again to clarify the geometry of the mounting rail (244). One recognizes the dovetail-shaped receptacle (249) for the holding elements (234), (236), (238) and (240) and the projections (245) and (247) running on the opposite side, which in the receptacles (266) of the Corner pieces (268) engage.

In den Fig. 18a und 18b sind Querschnitte von erfindungsgemäßen Luftzuführungsvorrichtungen (280) und (282) dargestellt. Die Luftzuführungseinrichtung (282) kann sowohl vom Boden oder von der Wand eines Raumes mit einem Luftkanal angefahren werden. Es kann aber auch eine statische Säule verkleidet werden, die von Luft umströmt wird. Dabei ergibt sich bei der Fig. 18a eine Sechseckform, bei der die die Profilelemente (26) und (28) verbindenden Flächen (zwei sind mit dem Bezugszeichen (284) und (286) versehen) mit stranggepreßten Profileckstücken (288) verbunden sind, wie sie dem Schnitt der Fig. 19b zu entnehmen sind.18a and 18b show cross sections of air supply devices (280) and (282) according to the invention. The air supply device (282) can be approached either from the floor or from the wall of a room with an air duct. However, it is also possible to cover a static column with air flowing around it. 18a results in a hexagon shape in which the surfaces connecting the profile elements (26) and (28) (two are provided with the reference symbols (284) and (286)) are connected with extruded profile corner pieces (288), such as they can be seen from the section in FIG. 19b.

Bei der Luftzuführungseinrichtung (280) gemäß Fig. 18b handelt es sich um ein halbes Achteck, das von einer Wand oder einer sonstigen geschlossenen Fläche ausgeht. Die die nicht näher bezeichneten Lufzuführungsflächen verbindenden Eckstücke (290) weisen eine Geometrie auf, wie sie beispielhaft der Fig. 19c zu entnehmen ist.The air supply device (280) according to FIG. 18b is a half octagon that starts from a wall or another closed surface. The corner pieces (290) connecting the air supply surfaces, which are not described in any more detail, have a geometry as can be seen, for example, from FIG. 19c.

In den Fig. 19a bis 19d sind allgemein unterschiedliche Formen von stranggepreßten Eckstücken zum Verbinden von Luftzuführungsflächen umfassend die vorzugsweise ineinandergreifenden Profilelemente (26) und (28) dargestellt. Das Eckstück der Fig. 19a entspricht dem Eckstück (268) gemäß Fig. 17. Das Eckstück (288) gemäß Fig. 19b ist für ein Sechseck (Fig. 18a) bestimmt. Erwähntermaßen ist das Eckstück (290) gemäß Fig. 19c für ein Achteck oder ein Teil davon bestimmt, wie es in Fig. 18b dargestellt ist. Schließlich ist das Eckstück (292) der Fig. 19d für ein Zwölfeck vorgesehen.19a to 19d show generally different shapes of extruded corner pieces for connecting air supply surfaces comprising the preferably interlocking profile elements (26) and (28). The corner piece of FIG. 19a corresponds to the corner piece (268) according to FIG. 17. The corner piece (288) according to FIG. 19b is intended for a hexagon (FIG. 18a). As mentioned, the corner piece (290) according to FIG. 19c is intended for an octagon or a part thereof, as shown in FIG. 18b. Finally, the corner piece (292) of FIG. 19d is provided for a twelve corner.

Sämtliche den Fig. 19a bis 19d zu entnehmenden Profile sind aus einem Ausgangsprofil (293) (Fig. 19e) durch Abkanten hergestellt. Hierdurch ergibt sich die Möglichkeit, beliebige Endprofilformen herzustellen. Um das Biegen zu erleichtern, ist eine Fase im Grundprofil eingezogen. Die Rastaufnahmen (266) können boden- und kopfseitig mit Gewindebuchsen bestückt werden bzw. es können Gewinde eingeschnitten werden, damit auf Stirnflächen der Profilelemente Abschlußflächen befestigt werden können.All of the profiles shown in FIGS. 19a to 19d are produced from an initial profile (293) (FIG. 19e) by folding. This gives the opportunity to produce any end profile shape. To make bending easier, a chamfer is drawn into the basic profile. The snap-in receptacles (266) can be fitted with threaded bushings on the bottom and top or threads can be cut so that end faces can be attached to the end faces of the profile elements.

Anhand der Fig. 20 und 21 soll noch einmal verdeutlicht werden, daß zwischen den Profilelementen (26) und (28) normalerweise vorhandene Durchtrittskanäle ganz oder teilweise mit vorzugsweise aus Kunststoff oder Gummi bestehenden Elementen verschließbar sind, die mit den Bezugszeichen (294) und (296) versehen sind. Dabei verschließen die Elemente (294) und (296) die von außen nicht sichtbaren Durchtrittskanäle. Um kontrolliert die Austrittsgeschwindigkeit der durch die erfindungsgemäße Luftzuführungseinrichtung einem Raum zuzuführenden Luft zu beeinflussen, können die Abdeckungen (296) bzw. (294) die Durchtrittskanäle über die gesamte Länge oder auch nur abschnittsweise verschließen. Dies soll anhand der Fig. 21 verdeutlicht werden. So verschließt die Abdeckung (294) nur bereichsweise einen sich zwischen den Profilelementen (26) und (28) erstreckenden Zuluftkanal, wohingegen das Element (296) über die gesamte Länge der Profile (26), (28) verläuft.20 and 21 should be made clear once again that passage channels normally present between the profile elements (26) and (28) can be completely or partially closed with elements preferably made of plastic or rubber, which are identified by the reference numerals (294) and ( 296) are provided. The elements (294) and (296) close the passage channels that are not visible from the outside. In order to control the exit speed of the air to be supplied to a room by the air supply device according to the invention, the covers (296) or (294) can close the passage channels over the entire length or only in sections. This should be clarified with reference to FIG. 21. For example, the cover (294) closes a supply air duct extending between the profile elements (26) and (28) only in some areas, whereas the element (296) extends over the entire length of the profiles (26), (28).

Die Abdeckelemente (296) und (298) umfassen zum einen die Innenvorsprünge (40) der Profilelemente (28) und liegen zum anderen dicht an den Außenflächen der diesen zugewandten Abschnitten der Profilelemente (26) an. Durch diese Maßnahme ist nicht nur eine sichere Abdichtung gewährleistet, sondern etwaige entstehende Vibrationen werden zusätzlich unterbunden.The cover elements (296) and (298) on the one hand enclose the inner projections (40) of the profile elements (28) and on the other hand lie tightly against the outer surfaces of the sections of the profile elements (26) facing them. This measure not only ensures a secure seal, but any vibrations that occur are additionally prevented.

In Fig. 24 ist eine weitere Ausführungsform einer Luftzuführungseinrichtung im Schnitt dargestellt, die zueinander abstandsveränderbare Profilelemente (26) und (28) umfaßt.24 shows a further embodiment of an air supply device in section, which comprises profile elements (26) and (28) which can be changed from one another.

Rein beispielhaft weist das raumseitig angeordnete Profilelement (28) einen mit einer Profilierung versehenen inneren Vorsprung (298) auf. Diese Profilierung kann durch Erhebungen bzw. Vertiefungen (304) und (306) gebildet werden. Um das Profilelement (28) in bezug auf die Profilelemente (26) der gegenüberliegenden Reihe in Abstand zu verändern, weisen die Federelemente verbindende Abschnitte (238) und (240) der Halterung Vorsprünge (300) und (302) auf, die in die die Profilierung bildenden Vertiefungen (304) bzw. (306) des Vorsprungs (298) einrasten können. Auf diese Weise ergibt sich eine problemlose Verstellbarkeit, wodurch wiederum die in den Raum abzugebende Luftmenge auf einfache Weise eingestellt werden kann. Im Ausführungsbeispiel weist jedes Federlement (238) bzw. (240) zwei Vorsprünge (300) bzw. (302) auf. Es können aber auch mehr aber auch nur ein Vorsprung sein.By way of example only, the profile element (28) arranged on the room side has an inner projection (298) provided with a profile. This profiling can be formed by elevations or depressions (304) and (306). In order to change the profile element (28) with respect to the profile elements (26) of the opposite row at a distance, the spring elements connecting sections (238) and (240) of the holder have projections (300) and (302) which fit into the Recessing recesses (304) or (306) of the projection (298) can snap. This results in a problem-free adjustability, which in turn makes it easy to adjust the amount of air to be discharged into the room. In the exemplary embodiment, each spring element (238) or (240) has two projections (300) or (302). But it can also be more than just a head start.
