Description
Die Erfindung betrifft ein Luftauslassgitter, das insbesondere für Öfen geeignet ist, sowie einen Ofen mit einem derartigen Luftauslassgitter.
Warmluft-Auslassgitter dienen zur Einstellung der Stärke eines Warmluftstroms, der aus einem Warmluftspeicher, der sich in einem Ofen befindet, in einen zu beheizenden Raum geleitet werden soll. Derartige Warmluft-Auslassgitter werden als Deckengitter bezeichnet, wenn sie in horizontaler Einbaulage an der Ofendecke angeordnet sind.
Warm air outlet grilles are used to set the level of hot air flow to be directed from a hot air storage located in an oven to a room to be heated. Such hot air outlet grille are referred to as a ceiling grid when they are arranged in a horizontal mounting position on the furnace roof.
Aus
Bei den herkömmlichen Warmluft-Auslassgittern ist eine Einstellung der Luftaustrittsrichtung somit nur in einem beschränkten Maße möglich. Dazu ist es erforderlich, den Anstellwinkel von Lamellen zu verändern. Damit wird zwar eine Veränderung der Luftaustrittsrichtung erreicht, dennoch ist der Luftaustritt auf eine Richtung beschränkt. Es ist nicht möglich, den Luftstrom so einzustellen, dass er gleichzeitig in mehrere Richtungen aus dem Ofen austreten kann. Im Wesentlichen strömt die Luft nach oben. Eine seitliche Luftströmung lässt sich nicht einstellen.In the conventional hot air outlet grille adjustment of the air outlet direction is thus possible only to a limited extent. For this it is necessary to change the angle of attack of slats. Thus, although a change in the air outlet direction is achieved, yet the air outlet is limited to one direction. It is not possible to adjust the flow of air so that it can simultaneously exit the oven in several directions. Essentially, the air flows upwards. A lateral air flow can not be adjusted.
Außerdem erfordert das Schwenken von Lamellen eine Mechanik, deren Lebensdauer deutlich geringer als die Lebensdauer des Ofens ist. Ohne eine hinreichende Wartung sitzt der Schwenkmechanismus innerhalb einer vergleichsweise kurzen Zeit fest, so dass die Einstellung der Luftaustrittsrichtung nicht mehr, nur eingeschränkt oder nur mit einem großen Kraftaufwand möglich ist.In addition, the pivoting of slats requires a mechanism whose life is significantly less than the life of the furnace. Without sufficient maintenance of the pivot mechanism is stuck within a relatively short time, so that the setting of the air outlet direction is no longer limited, or only with great effort is possible.
Schließlich sind die bekannten Luftauslassgitter nur schwer zu reinigen, was insbesondere dann nachteilig ist, wenn die Luftauslassgitter Bestandteil eines Ofens sind. Bei Revisionsarbeiten ist eine aufwendige Demontage der bekannten Luftauslassgitter erforderlich.Finally, the known Luftauslassgitter are difficult to clean, which is particularly disadvantageous when the Luftauslassgitter are part of a furnace. For maintenance work, a complicated disassembly of the known air outlet grille is required.
Weitere Luftauslassgitter sind aus
Aufgabe der Erfindung ist es, die Nachteile nach dem Stand der Technik zu beseitigen. Es soll insbesondere ein Luftauslassgitter, das insbesondere als Deckengitter für Öfen geeignet ist, angegeben werden, das es ermöglicht, einzustellen, dass der Luftstrom in einer oder mehreren Richtungen austritt. Ferner soll ein Ofen mit einem solchen Luftauslassgitter angegeben werden.The object of the invention is to eliminate the disadvantages of the prior art. In particular, an air outlet grille, which is particularly suitable as a ceiling grate for stoves, be specified, which makes it possible to adjust that the air flow exits in one or more directions. Furthermore, an oven should be specified with such a Luftauslassgitter.
Diese Aufgabe wird durch die Merkmale der Ansprüche 1, 12 und 15 gelöst. Zweckmäßige Ausgestaltungen der Erfindungen ergeben sich aus den Merkmalen der Unteransprüche.This object is solved by the features of
Nach Maßgabe der Erfindung ist ein Luftauslassgitter vorgesehen, das aufweist:
- einen Grundrahmen zur Anordnung an einer Wandöffnung, wobei der Grundrahmen eine Luftaustrittsöffnung umgibt und eine Oberkante aufweist;
- ein Verschlussmittel zum Öffnen und Verschließen der Luftaustrittsöffnung;
- eine Deckplatte, die unter Ausbildung eines umlaufenden Spaltes von der Oberkante des Grundrahmens beabstandet angeordnet ist; und
- Verschlusselemente zum Verschließen und Öffnen des Spaltes.
- a base frame for mounting on a wall opening, the base frame surrounding an air outlet opening and having an upper edge;
- a closure means for opening and closing the air outlet opening;
- a cover plate spaced from the upper edge of the base frame to form a circumferential gap; and
- Closing elements for closing and opening the gap.
Das erfindungsgemäße Luftauslassgitter ist insbesondere für einen Ofen geeignet. Das erfindungsgemäße Luftauslassgitter kann als Deckengitter eingesetzt werden, wenn es in horizontaler Lage an einer Ofendecke angeordnet ist. Die Ofendecke sollte dabei von der Decke eines zu beheizenden Raumes beabstandet sein. Wird das Luftauslassgitter hingegen nicht als Deckengitter, also nicht in horizontaler Lage an einer Ofendecke, verwendet, so sollte entsprechend die Ofenwand, in die das erfindungsgemäße Luftauslassgitters eingesetzt wird, von einer Wand des zu beheizenden Raumes beabstandet sein, in den die Luft eintreten soll.The air outlet grille according to the invention is particularly suitable for an oven. The air outlet grille invention can be used as a ceiling grid when it is arranged in a horizontal position on a furnace roof. The oven ceiling should be spaced from the ceiling of a room to be heated. On the other hand, if the air outlet grille is not used as a ceiling grate, ie not in a horizontal position on a furnace roof, then the furnace wall into which the air outlet grille according to the invention is inserted should be spaced from a wall of the space to be heated into which the air is to enter.
Die Deckplatte ist vorzugsweise parallel oder im Wesentlichen parallel zur Luftaustrittsöffnung angeordnet. Ist das erfindungsgemäße Luftauslassgitter ein Deckengitter, so verhindert die Deckplatte einen senkrechten Luftaustritt. Vielmehr strömt die Luft durch die Luftaustrittsöffnung gegen die Deckplatte und wird von dort in Richtung des Spaltes gelenkt. Dieser Spalt verläuft seitlich unterhalb des Deckengitters und oberhalb der Oberkante des Grundrahmens, so dass der Strom seitlich, also in horizontaler Richtung aus dem erfindungsgemäßen Luftauslassgitter austreten kann, und zwar dort, wo der Luftaustritt nicht von einem der Verschlusselemente verhindert wird. Mittels der Verschlusselemente kann der Nutzer des Deckengitters einstellen, in welcher oder welchen horizontalen Richtungen der Luftstrom aus dem Deckengitter austritt. Die Angaben "vertikale Richtung" und "horizontale Richtung" beziehen sich dabei auf die Verwendung des erfindungsgemäßen Luftauslassgitters als Deckengitter. Wird das Luftauslassgitter hingegen nicht als Deckengitter, also nicht in horizontaler Lage an einer Ofendecke, verwendet wird, so ändern sich die Austrittsrichtungen des austretenden Luftstroms entsprechend.The cover plate is preferably arranged parallel or substantially parallel to the air outlet opening. If the air outlet grille according to the invention is a ceiling grille, then the cover plate prevents a vertical air outlet. Rather, the air flows through the air outlet opening against the cover plate and is directed from there in the direction of the gap. This gap extends laterally below the ceiling grid and above the upper edge of the base frame, so that the flow can escape laterally, ie in the horizontal direction from the air outlet grille according to the invention, specifically where the air outlet is not prevented by one of the closure elements. By means of the closure elements, the user of the ceiling grid can adjust, in which or which horizontal directions the air flow exits from the ceiling grid. The statements "vertical direction" and "horizontal direction" refer to the use of the air outlet grille according to the invention as a ceiling grid. If, on the other hand, the air outlet grille is not used as a ceiling grille, ie not in a horizontal position on a furnace roof, the outlet directions of the exiting air flow will change accordingly.
Zusätzlich zu den Verschlusselementen kann auch die Deckplatte demontierbar sein. Damit kann, wenn das Luftauslassgitter ein Deckengitter ist, ein Luftaustritt in vertikaler Richtung erreicht werden, wenn die Deckplatte demontiert ist. Das erfindungsgemäße Luftauslassgitter erlaubt es einen Nutzer, sowohl einer vertikalen Luftstrom einzustellen, indem er die Deckplatte vom Grundrahmen entfernt, als auch horizontale Luftströme, indem er die Deckplatte an dem Grundrahmen anbringt und zumindest eines der Verschlusselemente entfernt. Dabei kann er je nach Anordnung der Verschlusselemente verschiedene Richtungen des horizontalen Luftstroms einstellen.In addition to the closure elements, the cover plate can also be removable. Thus, when the air outlet grille is a ceiling grille, air leakage in the vertical direction can be achieved when the cover plate is disassembled. The air outlet grille according to the invention allows a user to adjust both a vertical air flow by removing the cover plate from the base frame and horizontal air streams by attaching the cover plate to the base frame and removing at least one of the closure elements. He can adjust depending on the arrangement of the closure elements different directions of the horizontal air flow.
Vorzugsweise ist zum Verschließen eines Abschnittes des Spaltes, der von der Oberkante des Grundrahmens und der Deckplatte begrenzt wird, jeweils ein Verschlusselement vorgesehen. Der Spalt ist vollständig verschlossen, wenn alle Abschnitte des Spaltes mit Verschlusselementen verschlossen sind. Der Spalt ist hingegen vollständig geöffnet, wenn keiner der Abschnitte des Spaltes mit Verschlusselementen verschlossen ist.Preferably, for closing a portion of the gap, which is delimited by the upper edge of the base frame and the cover plate, in each case a closure element is provided. The gap is completely closed when all sections of the gap are closed with closure elements. The gap, however, is completely open when none of the sections of the gap is closed with closure elements.
Vorzugsweise sind zwei oder mehr, stärker bevorzugt drei oder mehr und besonders bevorzugt vier oder mehr Verschlusselemente vorgesehen. Jedes Verschlusselement, das einen Abschnitt des Spaltes verschließt, verhindert den Austritt des Luftstroms in diesem Abschnitt des Spaltes.Preferably, two or more, more preferably three or more, and most preferably four or more shutter members are provided. Each closure member which closes a portion of the gap prevents the escape of airflow in that portion of the gap.
Zweckmäßigerweise ist an dem Grundrahmen für jedes Verschlusselement zumindest ein Halteelement zur lösbaren Befestigung des Verschlusselementes ausgebildet. Mittels des Halteelementes kann jedes Verschlusselement derart an dem Grundrahmen befestigt werden, dass es einen Abschnitt des Spaltes verschließt, wodurch der Luftaustritt durch diesen Abschnitt des Spaltes verhindert wird. Das Halteelement lässt jedoch auch eine Demontage des Verschlusselementes zu, wodurch ein horizontaler Austritt des Luftstroms aus dem Deckengitter erreicht wird. Das Halteelement ist vorzugsweise an der der Luftaustrittsöffnung zugewandten Innenseite des Grundrahmens ausgebildet. Dadurch wird die Montage und Demontage des Verschlusselementes erleichtert. Vorzugsweise sind für jedes Verschlusselement zwei Halteelemente an dem Grundrahmen vorgesehen.Conveniently, at least one retaining element for releasable attachment of the closure element is formed on the base frame for each closure element. By means of the retaining element, each closure element can be so on the base frame be fastened so that it closes a portion of the gap, whereby the air outlet is prevented by this portion of the gap. However, the retaining element also allows disassembly of the closure element, whereby a horizontal outlet of the air flow is achieved from the ceiling grid. The retaining element is preferably formed on the inside of the base frame facing the air outlet opening. As a result, the assembly and disassembly of the closure element is facilitated. Preferably, two retaining elements are provided on the base frame for each closure element.
Zweckmäßigerweise grenzen Verschlusselemente, die aneinander angrenzende Abschnitte des Spaltes verschließen, mit ihren Stirnkanten aneinander an. Sind alle Verschlusselemente an dem Grundrahmen montiert, so bilden die Verschlusselemente gemeinsam einen Einsetzrahmen, der die Lufteintrittsöffnung umschließt.Conveniently, closure elements that close adjoining sections of the gap adjoin one another with their end edges. If all closure elements are mounted on the base frame, then the closure elements together form an insertion frame which encloses the air inlet opening.
Die Verschlusselemente können als demontierbare Seitenwände ausgebildet sein. Jedes der Verschlusselemente kann dabei eine der Seitenwände bilden. Weist der Grundrahmen eine rechteckige Kontur auf, so sind die Verschlusselemente vorzugsweise so ausgebildet, dass jedes der Verschlusselemente einen Abschnitt des Spaltes verschließt, der einer Seite des Grundrahmens entspricht. Bei einer rechteckigen Kontur des Grundrahmens sind somit vier Verschlusselemente erforderlich, um den Spalt vollständig zu verschließen.The closure elements may be formed as removable side walls. Each of the closure elements can form one of the side walls. If the base frame has a rectangular contour, the closure elements are preferably designed such that each of the closure elements closes a section of the gap which corresponds to one side of the base frame. In a rectangular contour of the base frame thus four closure elements are required to completely close the gap.
Der Grundrahmen kann auch eine andere Kontur als eine rechteckige Kontur aufweisen. Weist der Grundrahmen eine rechteckige Kontur auf, so kann er beispielsweise Seitenmaße aufweisen, die zwischen 10 und 50 cm liegen. Beispielsweise kann der Grundrahmen eine Länge aufweisen, die zwischen 20 und 40 cm liegt, und eine Breite, die zwischen 25 und 30 cm liegt. In einer bevorzugten Ausführungsform der Erfindung hat der erfindungsgemäße Grundrahmen eine Länge von 32 cm und eine Breite von 22 cm, wobei die Länge und Breite jeweils um +/- 5 cm variieren können. Unabhängig von der Kontur des Grundrahmens kann dessen Höhe beispielsweise zwischen 1 und 5 cm liegen, bevorzugt zwischen 1,5 und 3 cm. Die Länge kennzeichnet dabei die Ausdehnung des Grundrahmens in Längenrichtung x, die Breite die Ausdehnung des Grundrahmens in Breitenrichtung y und die Höhe seine Ausdehnung in Höhenrichtung z.The base frame may also have a different contour than a rectangular contour. If the base frame has a rectangular contour, it can, for example, have side dimensions that lie between 10 and 50 cm. For example, the base frame may have a length that is between 20 and 40 cm and a width that is between 25 and 30 cm. In a preferred embodiment of the invention, the base frame according to the invention has a length of 32 cm and a width of 22 cm, wherein the length and width can vary in each case by +/- 5 cm. Regardless of the contour of the base frame whose height can be, for example, between 1 and 5 cm, preferably between 1.5 and 3 cm. The length indicates the extent of the base frame in the length direction x, the width of the extension of the base frame in the width direction y and the height of its extension in the height direction z.
Das Verschlussmittel kann bewegliche und/oder betätigbare Elemente aufweisen, mit denen der Luftdurchtritt durch die Luftaustrittsöffnung gesteuert werden kann. In einer bevorzugten Ausführungsform des erfindungsgemäßen Luftauslassgitters weist das Verschlussmittel eine erste Gitterplatte und eine zweite Gitterplatte auf, wobei eine der Gitterplatten gegen die andere Gitterplatte verschiebbar ist. Dazu kann vorgesehen sei, dass eine der Gitterplatten, beispielsweise die zweite Gitterplatte, mittels eines Griffes, der durch eine Öffnungen in der Deckplatte geführt ist, verschiebbar ist. Alternative Verschlussmittel sind Klappen oder Lamellen.The closure means may comprise movable and / or actuatable elements with which the passage of air through the air outlet opening can be controlled. In a preferred embodiment of the air outlet grille according to the invention, the closure means on a first grid plate and a second grid plate, wherein one of the grid plates against the other grid plate is displaceable. For this purpose, it may be provided that one of the grid plates, for example, the second grid plate, by means of a handle which is guided through an opening in the cover plate, is displaceable. Alternative closure means are flaps or fins.
Das Verschlussmittel ist vorzugsweise an der Unterkante des Grundrahmens angeordnet. Dazu kann der Grundrahmen einen umlaufenden Steg aufweisen, der sich von der Unterkante in die Luftaustrittsöffnung erstreckt und im Folgenden auch als Innensteg bezeichnet wird. Auf dem Innensteg kann die erste Gitterplatte aufliegen, auf der wiederum die zweite Gitterplatte aufliegt. An dem Innensteg können Fixierungs- und Führungsstifte befestigt sein, die sich in Richtung der Oberkante des Grundrahmens erstrecken, und die zum einen die erste Gitterplatte an dem Steg unbeweglich fixieren und zum anderen Führungen für die zweite Gitterplatte sind. Dazu weist die erste Gitterplatte Rundlöcher auf, durch die die Fixierungs- und Führungsstifte geführt sind, während die zweite Gitterplatte Langlöcher oder Ausnehmungen aufweist, die eine Verschiebung der zweiten Gitterplatte auf der ersten Gitterplatte ermöglichen und durch die Fixierungs- und Führungsstifte ebenfalls geführt sind. Die erste und zweite Gitterplatte weisen korrespondierende Öffnungen und Gitterstreben auf. Das Verschlussmittel ist geöffnet, wenn die Öffnungen der ersten und der zweiten Gitterplatte übereinander liegen. Das Verschlussmittel ist geschlossen, wenn die Öffnungen der ersten Gitterplatte von den Gitterstreben der zweiten Gitterplatte bedeckt sind. Dabei sind die Öffnungen der zweiten Gitterplatte von den Gitterstreben der ersten Gitterplatte verschlossen. Die Breite der Öffnungen des ersten Gitters sollte der Breite der Öffnungen des zweiten Gitters entsprechen. Die Breite der Gitterstreben des ersten Gitters sollte der Breite der Gitterstreben des zweiten Gitters entsprechen. Bei beiden Gittern sollte die Breite der Öffnungen der Breite der Gitterstreben entsprechen. Die Breite der Öffnungen und Gitterstreben kann beispielsweise zwischen 0,5 und 1,5 cm betragen, vorzugsweise zwischen 0,8 und 1,2 cm liegen.The closure means is preferably arranged on the lower edge of the base frame. For this purpose, the base frame may have a circumferential web which extends from the lower edge into the air outlet opening and is also referred to below as inner web. On the inner web, the first grid plate rest on which in turn rests the second grid plate. On the inner web fixation and guide pins may be attached, which extend in the direction of the upper edge of the base frame, and on the one hand immovably fix the first grid plate to the web and on the other guides for the second grid plate. For this purpose, the first grid plate on circular holes through which the fixing and guide pins are guided, while the second grid plate has slots or recesses, which allow a displacement of the second grid plate on the first grid plate and are also guided by the fixing and guide pins. The first and second grid plates have corresponding openings and grid struts. The closure means is opened when the openings of the first and the second grid plate are superimposed. The closure means is closed when the openings of the first grid plate are covered by the grid struts of the second grid plate. The openings of the second grid plate are closed by the grid struts of the first grid plate. The width of the openings of the first grid should be the width of the Correspond to openings of the second grid. The width of the grating struts of the first grating should correspond to the width of the grating struts of the second grating. In both grids, the width of the openings should correspond to the width of the grid struts. The width of the openings and grid struts may for example be between 0.5 and 1.5 cm, preferably between 0.8 and 1.2 cm.
Damit die zweite Gitterplatte gegen die erste Gitterplatte verschoben werden kann, weist die zweite Gitterplatte an einer Seitenkante einen schmaleren Rand auf als die erste Gitterplatte. Die Breite des Randes der ersten Gitterplatte an ihrer entsprechenden Seitenkante sollte dabei die Breite des Randes der zweiten Gitterplatte an dieser Seitenkante um die Breite einer Gitterstrebe übersteigen.So that the second grid plate can be displaced against the first grid plate, the second grid plate has a narrower edge on one side edge than the first grid plate. The width of the edge of the first grid plate at its corresponding side edge should thereby exceed the width of the edge of the second grid plate at this side edge by the width of a grid strut.
Fixierungs- und Führungsstifte können einen Durchmesser aufweisen, der beispielsweise zwischen 0,3 und 1,5 cm liegt. Vorzugsweise erstrecken sich die Fixierungs- und Führungsstifte nicht bis zur Oberkante des Grundrahmens, sondern enden unterhalb der Oberkante des Grundrahmens. Vorzugsweise sind die Fixierungs- und Führungsstifte an den Ecken des Grundrahmens auf dem Innensteg angeordnet. Vorzugsweise haben alle Fixierungs- und Führungsstifte die gleiche Ausdehnung in Höhenrichtung, beispielsweise eine Ausdehnung von 0,5 bis 1,5 cm, besonders bevorzugt von 1 cm.Fixation and guide pins may have a diameter which is for example between 0.3 and 1.5 cm. Preferably, the fixing and guide pins do not extend to the upper edge of the base frame, but end below the upper edge of the base frame. Preferably, the fixing and guide pins are arranged at the corners of the base frame on the inner web. Preferably, all fixation and guide pins have the same extent in the height direction, for example, an extension of 0.5 to 1.5 cm, more preferably of 1 cm.
Es kann vorgesehen sein, dass die Deckplatte mittels Abstandshaltern von der Oberkante des Grundrahmens beabstandet gehalten ist. Bei diesen Abstandshaltern kann es sich um Stifte handeln, die im Folgenden als Deckplattenstifte bezeichnet werden. Die Abstandshalter können auf den Fixierungs- und Führungsstiften aufliegen und/oder von den Fixierungs- und Führungsstiften gehalten werden. Beispielsweise kann ein Teil oder alle Fixierungs- und Führungsstifte als Hohlzylinder ausgebildet sein, die an ihrer der Deckplatte zugewandten Stirnseite offen sind. In die Hohlzylinder kann dann ein Abstandshalter eingeführt werden. Auf diese Weise wird das Einsetzen und Abnehmen der Deckplatte von dem Grundrahmen erleichtert. Die Abstandshalter sind dabei so dimensioniert, dass der Spalt zwischen der Oberkante des Grundrahmens und der Deckplatte beispielsweise eine Ausdehnung in Höhenrichtung z von 0,5 bis 5 cm, stärker bevorzugt von 1 bis 3 cm, besonders bevorzugt von 1,5 bis 2,5 cm aufweist.It can be provided that the cover plate is held by means of spacers spaced from the upper edge of the base frame. These spacers may be pins, hereinafter referred to as cover plate pins. The spacers may rest on the fixation and guide pins and / or be held by the fixation and guide pins. For example, a part or all fixing and guide pins may be formed as a hollow cylinder, which are open at its end face facing the cover plate. In the hollow cylinder can then be inserted a spacer. In this way, the insertion and removal of the cover plate is facilitated by the base frame. The spacers are dimensioned so that the gap between the top edge of the base frame and The cover plate, for example, has an extension in the height direction z of 0.5 to 5 cm, more preferably from 1 to 3 cm, particularly preferably from 1.5 to 2.5 cm.
Weist der Grundrahmen eine rechteckige Kontur auf, so kann vorgesehen sein, dass zwei sich diagonal gegenüberliegende Fixierungs- und Führungsstifte als Hohlzylinder ausgebildet sind und zwei andere sich diagonal gegenüberliegende Fixierungs- und Führungsstifte als Vollzylinder ausgebildet sind. Auf den Vollzylindern stehen erste Abstandshalter auf, während zweite Abstandshalter in die Hohlzylinder mit ihren Enden eingeführt sind. Die zweiten Abstandshalter müssen dann länger sein als die ersten Abstandshalter, wenn die Fixierungs- und Führungsstifte die gleiche Ausdehnung in Höhenrichtung z aufweisen.If the base frame has a rectangular contour, it can be provided that two fixing pins and guide pins, which are located diagonally opposite each other, are designed as hollow cylinders and two other fixing pins and guide pins are formed as solid cylinders. On the solid cylinders are first spacers, while second spacers are inserted into the hollow cylinder with their ends. The second spacers must then be longer than the first spacers, if the fixing and guide pins have the same extent in the height direction z.
An der Oberkante des Grundrahmens kann ein Steg ausgebildet sein, und zwar an der Seite, die der Luftaustrittsöffnung abgewandt ist. Das ist die Außenseite des Grundrahmens. Dieser Steg wird im Folgenden auch als Außensteg bezeichnet. Wird der Grundrahmen in die Wandöffnung eingebracht, so liegt er an den Seitenwänden der Öffnung an. Der Außensteg bildet eine Blende, die an der Außenseite der Wand anliegt.At the upper edge of the base frame, a web may be formed, on the side facing away from the air outlet opening. This is the outside of the base frame. This web is also referred to below as the outer web. If the base frame is inserted into the wall opening, it rests against the side walls of the opening. The outer bar forms a panel which bears against the outside of the wall.
An den Verschlusselementen können Verbindungselemente ausgebildet sein, die in die Halteelemente des Grundrahmens eingreifen, wenn ein Verschlusselement in den Grundrahmen eingesetzt wird. Dabei kann eine Steck-, Rast- oder Verriegelungsverbindung zwischen dem Grundrahmen und dem Verschlusselement hergestellt werden. Die Verbindung muss jedoch auch eine Demontage des Verschlusselementes von dem Grundrahmen zulassen.On the closure elements connecting elements may be formed, which engage in the holding elements of the base frame when a closure element is inserted into the base frame. In this case, a plug-in, latching or locking connection between the base frame and the closure element can be produced. However, the connection must also allow disassembly of the closure element from the base frame.

Die Anzahl und Position der Verbindungselemente entspricht dabei der Anzahl und Position der Halteelemente, die zur Befestigung des Verschlusselementes an dem Grundrahmen ausgebildet sind. Bei dem Verbindungselement kann es sich beispielsweise um eine Lasche handeln. Ist das Verschlusselement an dem Grundrahmen befestigt, so erstreckt es sich vorzugsweise in dieselbe Richtung, die Höhenrichtung z, wie der Grundrahmen. Dabei liegt es mit seiner Außenseite, d. h. der Seite, die der Luftaustrittsöffnung abgewandt ist, an der Innenseite des Grundrahmens an. Die Höhe des Verschlusselementes, also dessen Ausdehnung in Höhenrichtung z, muss größer als die Ausdehnung des Spaltes in dieser Richtung sein. Vorzugsweise übersteigt die Ausdehnung des Verschlusselementes in dieser Richtung die des Spaltes um 0,5 cm oder mehr, bevorzugt um 1 cm oder mehr.
