Abstract

The ventilation cap is allocated at least one elastic sealing unit (7) made from a multi-layered element (10). The element is a multi-layered flap, especially a sealing band. The element has comb-shaped indentations. The material of the element is flat, and the layers (31,33,35) are located to overlap each other. At least one layer (31,33,35) is provided with indentations, where the indentations run lateral to the longitudinal direction of the element. The strips located between the indentations have differing widths.

Description

Die Erfindung betrifft ein Lüftungselement für Dächer, mit einer im First , Walm oder Gratbereich angeordneten Lüfterkappe, der mindestens ein elastisches Abdichtorgan zugeordnet ist.The invention relates to a ventilation element for roofs, with one in the ridge, hip or ridge area arranged fan cap, the at least one elastic Sealing member is assigned.

Es ist bekannt, bei derartigen Lüftungselementen Abdichtorgane aus luftdurchlässigen Schaumstoff einzusetzen. Nachteilig ist, daß bei unterschiedlichen Abstandsdifferenzen und/oder scharfkantigen Übergängen der Bedachungsmaterialien der Schaumstoff aufgrund seiner Struktur nicht in der Lage ist, eine hinreichende Dichtigkeit, zum Beispiel gegenüber Regen und Flugschnee, zu erzielen. Ferner ist nachteilig, daß der Schaumstoff nicht alterungsbeständig ist und im Laufe der Zeit versprödet und bröckelig wird, so daß die Funktionsbeständigkeit nicht gewährleistet ist. Schließlich erfordert Schaumstoff einen starken Komprimierungsdruck, der die Verlegung erschwert und oftmals zu unbefriedigenden Arbeits- und Abdichtergebnissen sowie einem optisch unschönen Aussehen führt; auch sind zugängliche Bereiche dem Vogelfraß ausgesetzt.It is known in such ventilation elements Sealing elements made of air-permeable foam use. The disadvantage is that with different Distance differences and / or sharp-edged Transitions of the roofing materials of the foam unable due to its structure is a sufficient tightness, for example against rain and flying snow. Further is disadvantageous that the foam is not resistant to aging is and becomes brittle over time and becomes crumbly, so that the functional stability is not guaranteed. Finally requires Foam a strong compression pressure that the installation is difficult and often unsatisfactory Work and sealing results as well as a optically unsightly appearance leads; are also accessible Areas exposed to bird feeding.

Es ist ferner bekannt, als Abdichtorgan für Lüftungselemente eine Bürstenleiste einzusetzen, wobei die Bürstenleiste eine Vielzahl von elastischen, in zumindest weitgehendst strömungsdichter Packung angeordneten Bürstenfäden aufweist. Nachteilig ist, daß die feinen Fadenenden -also die einzelnen Fadenspitzen- umknicken können, beispielsweise wenn sie gegen Hindernisse wie rauhe Stellen, Kanten usw. stoßen, wodurch diese auseinanderklaffen und somit die Dichtigkeit in Frage gestellt ist. Schließlich ist in kritischen Bereichen, beispielsweise Eckbereichen des Bedachungsmaterials, nicht sichergestellt, daß die Borsten bis in diese Bereiche hineinreichen. Ferner neigen die Bürstenfäden dazu, sich aufzustellen beziehungsweise bei starker Erwärmung des Bedachungsmaterials abzuheben und bei Abkühlung nicht mehr in die Ausgangsstellung zurückzugehen, wodurch in die so freigegebenen Bereiche, besonders bei Winddruck, Flugschnee und Schlagregen über die nunmehr offenen Bereiche eindringen können. Weiterhin besteht die Gefahr, daß durch Umwelteinflüsse, starke Sonneneinstrahlung (UV-Strahlung) diese sehr feinen Kunststoff-Bürstenfäden verspröden und abbrechen, was wiederum die Dichtigkeit stark vermindert. Ein weiterer Nachteil ist, daß bei starkem Winddruck die Bürstenfäden keilförmig auseinandergespreizt werden und dadurch große Eintriebsöffnungen für Flugschnee und Schlagregen entstehen. Auch passiert es, daß die feinen Kunststoff-Bürstenfäden durch Umwelteinflüsse verkleben und sich wie Rechenzinken zusammenballen, wodurch Freiräume geschaffen werden, durch welche wiederum Schnee und Regen eindringen können. Zusätzlich verlieren die losen Bürstenfäden ihr wichtigstes Merkmal, nämlich die Elastizität, wodurch die Abdichtung stark vermindert wird.It is also known as a sealing member for ventilation elements to insert a brush strip, whereby the brush strip a variety of elastic, in arranged at least largely flow-tight packing Has brush threads. The disadvantage is that the fine thread ends - the individual thread tips - can twist, for example if against obstacles such as rough spots, edges etc., causing them to diverge and thus the tightness is questioned. Finally, in critical areas, for example Corner areas of the roofing material, not ensured that the bristles up into these areas extend. Furthermore, the brush threads tend to line up or in the case of strong Lift off the roofing material and at Cooling no longer return to the starting position, whereby in the areas thus released, especially with wind pressure, flying snow and Driving rain entering the now open areas can. There is also a risk that due to environmental influences, strong sunlight (UV radiation) these very fine plastic brush threads become brittle and break off, which in turn the tightness is greatly reduced. Another The disadvantage is that the brush threads in strong wind pressure be spread apart in a wedge shape and thereby large entry openings for flying snow and driving rain arise. It also happens that the fine plastic brush threads due to environmental influences stick together and clump together like rake tines, creating space, through which snow and rain penetrate can. In addition, the loose brush threads lose their most important characteristic, namely elasticity, which greatly reduces the seal.

Ein Lüftungselement für Dächer, mit einer im First-, Walm- oder Gratbereich anzuordnenden Lüfterklappe und mit mindestens einem an den Randbereich der Lüfterklappe anschließenden Abdichtorgan ist aus der DE 296 08 830 U1 bekannt. Das Abdichtorgan weist wenigstens zwei übereinander angeordnete, in Richtung der Längsachse der Lüfterklappe verlaufende, flache Abdichtungsstreifen auf. Jeder Abdichtungsstreifen weist eine Vielzahl von im Wesentlichen quer zur Richtung der Längsachse verlaufenden, elastischen Querstreifen auf.A ventilation element for roofs, with an inside Fan flap to be arranged in the ridge, hip or ridge area and with at least one to the edge area the sealing flap connecting the fan flap is known from DE 296 08 830 U1. The sealing element has at least two superimposed, in the direction of the longitudinal axis of the fan flap running, flat sealing strips. Everyone Sealing strip has a variety of essentially transverse to the direction of the longitudinal axis, elastic horizontal stripes.

Aufgabe der Erfindung ist es daher, ein Lüftungselement der eingangs genannten Art zu schaffen, bei dem eine optimale Abdichtung gewährleistet ist und das sich gleichmäßig und homogen jedem Bedachungsmaterial anpaßt.The object of the invention is therefore a ventilation element to create of the type mentioned at which ensures an optimal seal and that is evenly and homogeneously any roofing material adapts.

Diese Aufgabe wird durch ein erfindungsgemäßes Lüftungselement gelöst, das die in Anspruch 1 genannten Merkmale auf weist. Dadurch, daß das Abdichtorgan als aus elastischem Material bestehendes Mehrlagenelement ausgebildet ist, wird eine sichere Abdichtung gewährleistet. Durch die besondere Ausbildung des Mehrlagenelementes sowie durch seine Flexibilität ist es in der Lage, sich jedem Bedachungsmaterial, beispielsweise Dachziegeln, Wellen, Profile oder dergleichen, anzupassen, wobei es sich sowohl in Vertiefungen als auch an Erhöhungen des Bedachungsmaterials problemlos anlegt. Das Mehrlagenelement ist als Leiste ausgebildet. Das im First- und Gratbereich angeordnete Lüftungselement ermöglicht eine Luftzirkulation und einen Luftaustausch im gesamten Dachaufbau, wodurch zum Beispiel Kondenzwasserbildung und daraus sich ergebene Schäden verhindert werden. Das Mehrlagenelement verhindert durch seine homogene Abdichtung beziehungsweise Anpassung an jedes Bedachungsmaterial den Eintrag von Schlagregen und Flugschnee und so weiter.This object is achieved by a ventilation element according to the invention solved that mentioned in claim 1 Features on points. The fact that the sealing member as a multilayer element made of elastic material is formed, a secure seal guaranteed. Through the special training of the multi-layer element as well as its flexibility is able to look at any roofing material for example roof tiles, waves, Profiles or the like to adjust, where it is both in depressions and in elevations of the Roofing material created without problems. The multi-layer element is designed as a bar. That in Ventilation element arranged in the ridge and ridge area enables air circulation and air exchange throughout the roof structure, which for example Condensation water formation and the resulting damage be prevented. The multi-layer element prevents through its homogeneous sealing respectively Adaptation to every roofing material Entry of driving rain and flying snow and so on.

Bevorzugt wird eine Ausführungsform des Lüftungselements, die sich dadurch auszeichnet, daß das Material Flächenmaterial ist und daß mehrere Lagen des Flächenmaterials übereinanderliegend angeordnet sind. Das Mehrlagenelement ist also von mehreren, vorzugsweise aus dem gleichen, elastische Eigenschaften aufweisenden Material hergestellten Lagen gebildet. Es wird ein Mehrlagenelement bevorzugt, das aus drei Lagen des Flächenmaterials gebildet ist. Die oberen Kanten des Flächenmaterials werden als Streifen aufeinandergelegt und miteinander verbunden, beispielsweise verschweißt. Durch das Verschweißen der Lagen des Mehrlagenelements zu einem Dichtungskörper, werden die Eigenschaften des Flächenmaterials, insbesondere die Elastizität in vorteilhafter Weise ausgenutzt, nämlich dadurch, daß das Mehrlagenelement eine hohe Anpassungsfähigkeit aufweist, wodurch eine gleichmäßige Abdichtung gegen den Eintrag von Regen und Schnee gewährleistet ist.An embodiment of the ventilation element is preferred, which is characterized in that the material Surface material is and that several layers of the surface material arranged one above the other are. So the multilayer element is made up of several preferably from the same, elastic properties layers made of material educated. A multilayer element is preferred that is made up of three layers of sheet material is. The top edges of the sheet material will be placed on top of each other as strips and connected to each other, for example welded. By welding the layers of the multilayer element into one Sealing body, the properties of the sheet material, especially the elasticity in advantageous Exploited way, namely that the multilayer element is highly adaptable has, whereby a uniform seal against ensures the entry of rain and snow is.

Weiterhin wird eine Ausführungsform des Lüftungselements vorgeschlagen, bei der zumindest zwei Lagen des Flächenmaterials zur Ausbildung des Mehrlagenelementes mit den Einschnitten und/oder den Freischnitten versehen sind. Die Einschnitte sind fertigungstechnisch sehr einfach und damit kostengünstig einbringbar. Sie weisen ferner den Vorteil auf, daß sie kleine Abstände zueinander realisieren, wodurch die Anpassungsfähigkeit wesentlich vergrößert und dennoch die Abdichtfunktion des Lüftungselements im montierten Zustand gewährleistet ist. Die Einschnitte können als Feinschnitte ausgebildet sein, wodurch die Anpassungsfähigkeit des Lüftungselements noch weiter verbessert werden kann. Ein weiterer Vorteil der Einschnitte ist, daß in das Mehrlagenelement eindringendes Regen- oder Tauwasser sofort auf die untere Lage des Mehrlagenelementes und auf das Dacheindeckungsmaterial abgeleitet wird. Die Einschnitte sind ausgehend von einer Längsseite des Mehrlagenelementes in dieses eingebracht, so daß zwischen zwei nebeneinanderliegenden Einschnitten ein Streifen gebildet ist, der südländischen Lüftungsvorhängen (Insektenschutzvorhängen) ähnlich ist. In einem anderen Ausführungsbeispiel des Lüftungselements wird ein Mehrlagenelement bevorzugt, bei dem die Einschnitte und/oder Freischnitte quer, insbesondere rechtwinklig, zur Längserstreckung des Mehrlagenelementes angeordnet sind. Es ist auch denkbar, daß ihr Verlauf gezackt oder wellenlinig ist. Durch diese Ausrichtung der Einschnitte wird verstärkt gewährleistet, daß die Form des Mehrlagenelementes auch im montierten Zustand erhalten bleibt.Furthermore, an embodiment of the ventilation element suggested at least two layers of the surface material to form the multilayer element with the incisions and / or the free cuts are provided. The incisions are production-related very simple and therefore inexpensive recoverable. They also have the advantage that they realize small distances from each other, whereby the adaptability significantly increased and nevertheless the sealing function of the ventilation element in the assembled condition is guaranteed. The incisions can be designed as fine cuts, thereby the adaptability of the ventilation element can be further improved. Another The advantage of the incisions is that in the multilayer element penetrating rain or condensation immediately on the lower layer of the multi-layer element and derived on the roofing material becomes. The incisions are based on one Introduced into the long side of the multilayer element, so that between two side by side Incisions a stripe is formed, the southern Ventilation curtains (insect screens) is similar. In another embodiment a multi-layer element is preferred for the ventilation element, where the incisions and / or free cuts across, especially at right angles, to Longitudinal extension of the multilayer element arranged are. It is also conceivable that their course serrated or is wavy. By aligning the Incisions will increasingly ensure that the Shape of the multi-layer element even when assembled preserved.

Weiterhin wird eine Ausführungsform des Lüftungselements bevorzugt, die sich dadurch auszeichnet, daß die Einschnitte und/oder Freischnitte der einzelnen Lagen winklig zueinander verlaufen. Es ist möglich, daß beispielsweise die Einschnitte der oberen Lage quer zur Längserstreckung des Mehrlagenelementes angeordnet sind und die Einschnitte der anderen darunterliegenden Lagen mit den Einschnitten und/oder Freischnitten der oberen Lage einen Winkel einschließen, so daß die Einschnitte und/oder Freischnitte der einzelnen Lagen -bei einer Betrachtung des Mehrlagenelementes von obensich kreuzen.Furthermore, an embodiment of the ventilation element preferred, which is characterized by that the cuts and / or cuts of the individual Layers run at an angle to each other. It is possible that, for example, the incisions of the upper Position transverse to the longitudinal extension of the multilayer element are arranged and the incisions the other layers below with the incisions and / or clearing the top layer enclose an angle so that the incisions and / or free cuts of the individual layers - with one Consideration of the multilayer element from above cross.

Die zwischen den Einschnitten und/oder Freischnitten liegenden Streifen der einzelnen Lagen sind unterschiedlich breit ausgebildet. Die Breite der Streifen innerhalb einer Lage ist also gleich, wobei die Streifenbreite von Lage zu Lage variiert werden kann. Bevorzugt wird ein Ausführungsbeispiel des Lüftungselements, das sich dadurch auszeichnet, daß die Streifenbreite der oberen Lage kleiner ist als die der mittleren Lage und daß die Streifenbreite der unteren Lage größer ist als die der mittleren und der oberen Lage. Die Streifenbreite ist also -bei einer Betrachtung des Mehrlagenelementes von oben- abgestuft und wird mit jeder Lage breiter. Als "unten" ist hier die Seite des Mehrlagenelementes. bezeichnet, die auf dem Bedachungsmaterial aufliegt. Die "obere" Seite des Mehrlagenelementes ist demgemäß diejenige Seite, die der unteren Seite gegenüberliegt.The between the cuts and / or free cuts horizontal stripes of the individual layers are different broadly trained. The width of the Stripes within a layer are the same, though the stripe width varies from layer to layer can be. An embodiment is preferred of the ventilation element, which is characterized by that the stripe width of the top layer is smaller than that of the middle layer and that the stripe width the lower layer is larger than that of the middle and top layer. The stripe width is - when considering the multilayer element graded from above and is with every layer wider. As "below" here is the side of the multilayer element. referred to on the roofing material rests. The "top" side of the Multilayer element is accordingly the side which is opposite the lower side.

Bevorzugt wird auch eine Ausführungsform des Lüftungselements, bei der die Länge der Streifen der einzelnen Lagen unterschiedlich groß ist. Durch die unterschiedlichen Längen der einzelnen Lagen weist das Mehrlagenelement unterschiedliche Dicken auf. Bevorzugt wird eine Ausführungsform des Lüftungselements, die sich dadurch auszeichnet, daß die Streifenlänge der oberen Lage kürzer ist als die der mittleren Lage und daß die Streifenlänge der unteren Lage länger ist als die der mittleren und oberen Lage. Die einzelnen Lagen liegen also schuppenartig übereinander.An embodiment of the ventilation element is also preferred, where the length of the strips of individual layers are of different sizes. Through the shows different lengths of the individual layers the multilayer element has different thicknesses. An embodiment of the ventilation element is preferred, which is characterized in that the Strip length of the top layer is shorter than that the middle layer and that the strip length of the lower layer is longer than that of the middle and top layer. The individual layers are therefore scale-like one above the other.

Weiterhin wird eine Ausführungsform des Lüftungselements bevorzugt, bei der die Dicke der einzelnen Lagen unterschiedlich groß ist. Besonders bevorzugt wird ein Ausführungsbeispiel, das sich dadurch auszeichnet, daß die obere Lage dicker ist als die mittlere Lage und daß die untere Lage dünner ist als die mittlere und obere Lage. Dadurch wird sichergestellt, daß die obere Lage die darunterliegenden Lagen aufgrund ihrer größeren Masse niederdrückt beziehungsweise niederhält, so daß diese sich sowohl in die Vertiefungen als auch an die Erhöhungen des Bedachungsmaterials anlegen.Furthermore, an embodiment of the ventilation element preferred where the thickness of each Layers is different in size. Particularly preferred is an embodiment that is characterized by that the top layer is thicker than that middle layer and that the lower layer is thinner than the middle and top layer. This ensures that the top layer is the ones underneath Layers depressed due to their greater mass or holds down so that this itself both in the recesses and in the elevations of the roofing material.

Bevorzugt wird weiterhin eine Ausführungsform des Lüftungselements, die sich dadurch auszeichnet, daß eine Lüfterkappe mit mindestens einem Mehrlagenelement einstückig ausgebildet ist. Dadurch ist es möglich, das Lüftungselement, also Kappe und Dichtungsleiste, zu einer Rolle aufzuwickeln, die einerseits platzsparend lagerbar beziehungsweise beförderbar und andererseits sehr einfach zu verlegen ist. Beim Verlegen wird die Rolle einfach auf dem Dach über einer Firstlatte ausgerollt, positioniert und befestigt. Der Zeitaufwand für die Verlegung des Lüftungselements ist dadurch sehr gering.An embodiment of the Ventilation element, which is characterized in that a fan cap with at least one multilayer element is formed in one piece. That is it possible, the ventilation element, i.e. cap and sealing strip, to wind up into a roll, on the one hand Can be stored or transported to save space and on the other hand very easy to install is. When laying, the roll is simply on the Rolled out roof over a ridge slat, positioned and attached. The time spent laying the ventilation element is therefore very low.

In den beiden Endbereichen 4 und 6 der Deckenwand 5 der Lüfterkappe 3 sind die Abdichtorgane 7 angeordnet, die in dem in Figur 1 gezeigten Ausführungsbeispiel als einzelne von der Lüfterkappe 3 trennbare Teile ausgebildet sind. Die Abdichtorgane 7 sind mit einer Klemmschiene 26 versehen, die auf die Lüfterkappe aufgeschoben beziehungsweise aufgesteckt ist. Alternativ dazu ist auch eine Befestigung der Abdichtorgane 7 und der Lüfterkappe 3 mittels einer Klips-Verbindung, einer Klebe-Verbindung, einer Schraub-Verbindung, einer Einschiebe-Verbindung, einer Schweiß-Verbindung oder dergleichen möglich. Die Abdichtorgane 7 können in einer vorteilhaften Ausführungsform der Erfindung einstückig mit der Lüfterkappe 3 ausgebildet sein. Unter "Einstückig" ist zu verstehen, daß das Lüftungselement aus einem Material ausgeformt wird. Das montagefertige Funktionsteil, also die Lüfterkappe 3 mit an ihr angebrachten beziehungsweise zugeordneten Abdichtorgane 7, wird aufgrund seiner Form, Funktion und Ausgestaltung auch als Mehrlagen-Dichtungsband bezeichnet. Die Abdichtorgane 7 dienen dazu, die unregelmäßig großen, zwischen der Oberseite 27 der Ziegel 19 und der Unterseite 29 der Firstziegel 23 liegenden Spalte derart zu verschließen, daß einerseits eine Luftzirkulation im Firstbereich möglich ist und daß andererseits ein Eindringen von Regen oder Schnee verhindert wird.In the two end regions 4 and 6 of the ceiling wall 5 the fan cap 3, the sealing members 7 are arranged, the in the embodiment shown in Figure 1 as a single separable from the fan cap 3 Parts are formed. The sealing elements 7 are provided with a clamping rail 26 which the fan cap pushed on or put on is.

In den Endbereichen 4 und 6 der Lüfterkappe 3 ist jeweils das Abdichtorgan 7 angeordnet, das als Mehrlagenelement 10 ausgebildet ist. Zur Beschreibung des Mehrlagenelements 10 wird auf die Figur 7 verwiesen. Das Mehrlagenelement 10 ist in der Seitenansicht ausgeklappt dargestellt (obere Abbildung) und weist hier drei aus einem Flächenmaterial hergestellte Lagen 31, 33 und 35 auf. Die im eingebauten Zustand übereinanderliegenden Lagen 31 bis 35 sind an einer Längsseite 37 leistenförmig miteinander verbunden, beispielsweise verschweißt, verklebt oder dergleichen. Besonders vorteilhaft ist es, das Mehrlagenelement aus einem Stück zu spritzen oder zu extrudieren (siehe Figur 7). Im eingebauten Zustand des Mehrlagenelements 10 liegen die Lagen 31 bis 35 übereinander, wobei die Lage 35 an der Oberseite 27 der Ziegel 19 aufliegt. Im folgenden wird deshalb die Lage 35 als untere Lage, die Lage 33 als mittlere Lage und die Lage 31 als obere Lage bezeichnet. Die Lagen 31 bis 35 weisen in diesem Ausführungsbeispiel die gleiche Länge L auf, jedoch unterschiedliche Dicken. Die obere Lage 31 weist hier die geringste und die mittlere Lage 33 die größte Dicke auf. Grundsätzlich ist es auch möglich, die Lagen des Mehrlagenelementes gleich stark beziehungsweise dick auszubilden. Die einzelnen Lagen des Mehrlagenelements 10 weisen luftdurchlässige Einschnitte 39 auf, die beabstandet zueinander und quer zur Längserstreckung des Abdichtorgans 7 angeordnet sind. Die Einschnitte 39 sind von der Längsseite 41 der Lagen 31, 33 und 35 in diese eingebracht, wodurch Streifen 43 gebildet werden, die im Bereich der Längsseite 41 der Lagen nicht miteinander verbunden sind. Wie aus der Draufsicht auf das Mehrlagenelement 10 der Figur 7 ersichtlich (untere Abbildung), weisen die Streifen 43 der oberen Lage 31 die gleiche Breite auf. Die Einschnitte 39 werden in einem Stanz- oder Schneidvorgang vor dem Verbinden der einzelnen Lagen miteinander in die planaufliegenden Lagen beziehungsweise in das Lüftungselement 1 eingebracht. Wird bei diesem Bearbeitungsvorgang Material an der Trennstelle abgetragen, so werden Freischnitte ausgebildet. Im Falle von Einschnitten wird kein Material abgetragen.In the end regions 4 and 6 of the fan cap 3 each arranged the sealing member 7, which as Multi-layer element 10 is formed. As description of the multilayer element 10 is shown in FIG directed. The multilayer element 10 is in a side view shown unfolded (upper figure) and here has three made of a sheet material manufactured layers 31, 33 and 35. The built in Condition of layers 31 to one above the other 35 are strip-shaped with one another on a longitudinal side 37 connected, for example welded, glued or the like. Particularly advantageous is to make the multilayer element from one piece inject or extrude (see Figure 7). in the installed state of the multilayer element 10 lie the layers 31 to 35 one above the other, the layer 35 on the top 27 of the brick 19 rests. Hereinafter layer 35 is therefore used as the lower layer, the layer 33 as the middle layer and the layer 31 as called upper layer. The layers 31 to 35 have in this embodiment, the same length L on, but different thicknesses. The top layer 31 shows the lowest and the middle position 33 the greatest thickness. Basically it is too possible, the layers of the multilayer element the same to train strong or thick. The single ones Layers of the multilayer element 10 have air permeable Incisions 39 that are spaced to each other and transverse to the longitudinal extent of the sealing member 7 are arranged. The incisions 39 are from the long side 41 of the layers 31, 33 and 35 introduced into this, whereby strips 43 are formed be in the area of the long side 41 of the layers are not connected. As from the Top view of the multi-layer element 10 of FIG. 7 visible (lower figure), the stripes show 43 of the upper layer 31 the same width. The Incisions 39 are made in a punching or cutting process before joining the individual layers together in the overlying locations respectively introduced into the ventilation element 1. Becomes in this machining process material on the Cutting point removed, so free cuts are formed. In the case of incisions, no material is used ablated.

Anhand der Luftzirkulation wird -gemäß Figur 1- die Funktion des Abdichtorgans 7 näher erläutert. Ein Luftstrom 45 strömt im Dachaufbau von der Traufe zum First. Der Luftstrom 45 tritt durch die Luftaustrittsöffnungen 8 der bandförmigen Lüfterkappe 3 hindurch und gelangt in den Zwischenraum 47, der sich zwischen dem Lüftungselement 1 und den Firstziegeln 23 ausbildet. Von dort gelangt der Luftstrom 45 durch einen Spalt, der zwischen der Unterseite 29 des Firstziegels 23 und der Oberseite 27 des Ziegels 19 gebildet ist, nach außen.Based on the air circulation - according to Figure 1- Function of the sealing member 7 explained in more detail. On Air flow 45 flows from the eaves in the roof structure to the ridge. The air flow 45 passes through the air outlet openings 8 of the band-shaped fan cap 3 through and into the space 47, the between the ventilation element 1 and the ridge tiles 23 trains. The airflow arrives from there 45 through a gap between the bottom 29 of the ridge tile 23 and the top 27 the brick 19 is formed, to the outside.

Gleiche Teile sind mit gleichen Bezugszeichen versehen, so daß insofern auf die Beschreibung zur Figur 1 verwiesen werden kann. Im folgenden wird lediglich auf die Unterschiede eingegangen. Die Lüfterkappe 3 ist mit den an den Endbereichen 4 und 6 angeordeneten Abdichtorganen 7 einstückig verbunden. Der Firstziegel 23, der hier auf der Deckenwand 5 aufliegt, wird von an der Lüfterkappe 3 angeordneten Abstandshaltern 25 getragen, die hier einstückig mit der Lüfterkappe in Form von Stegen ausgebildet sind . und sich in Längsrichtung der Lüfterkappe erstrekken (siehe Figur 3). Eine perspektivische Detailzeichnung der Lüfterkappe 3 gemäß Figur 2 ist in Figur 3 abgebildet. In die Abstandshalter 25 sind Aussparungen 49 eingebracht, auf deren Funktion im folgenden eingegangen wird. Der in den Firstbereich aufsteigende Luftstrom 45 gelangt durch die Durchtrittsöffnungen 8 in den Zwischenraum 47, der -wie oben beschrieben- unterhalb des Firstziegels 23 angeordnet ist, und von dort durch in den Abstandshaltern 25 angeordneten randoffenen Aussparungen 49 nach außen. Anstelle der in Figur 3 dargestellten Aussparungen 49 können auch Ausnehmungen und/oder Durchtrittsöffnungen in den hier stegförmigen Abstandshaltern 25 vorgesehen sein.Figure 2 shows a side view of the ridge area of the roof according to Figure 1 with another embodiment of the ventilation element 1. Same parts are provided with the same reference numerals, so that insofar referred to the description of Figure 1 can be. In the following, only the Differences entered. The fan cap 3 is with the sealing elements arranged at the end regions 4 and 6 7 connected in one piece. The ridge tile 23, which rests here on the ceiling wall 5, is by spacers arranged on the fan cap 3 25 worn here in one piece the fan cap are designed in the form of webs. and extend in the longitudinal direction of the fan cap (see Figure 3). A perspective detail drawing the fan cap 3 according to FIG. 2 is in Figure 3 shown. In the spacers 25 are Recesses 49 introduced, on their function in following is discussed. The one in the ridge area rising air flow 45 passes through the passage openings 8 in the space 47, the like described above - arranged below the ridge tile 23 and from there in the spacers 25 arranged open-edge recesses 49 outward. Instead of that shown in Figure 3 Recesses 49 can also be recesses and / or Through openings in the web-shaped spacers here 25 may be provided.

Wie aus Figur 3 ersichtlich, sind die Lüfterkappe 3 und die Abdichtorgane 7 des Lüftungselements 1 einstückig miteinander ausgebildet. Die Luftdurchtrittsöffnungen 8 weisen hier eine rechteckförmige Kontur auf. Die von der Traufe zum First strömende Luft gelangt über die Luftdurchtrittsöffnungen 8 und die in den Abstandshaltern 25 angeordneten Aussparungen 49 nach außen.As can be seen from FIG. 3, the fan cap 3 and the sealing members 7 of the ventilation element 1 in one piece trained with each other. The air openings 8 have a rectangular shape here Contour on. The one flowing from the eaves to the ridge Air passes through the air passage openings 8 and the recesses arranged in the spacers 25 49 to the outside.

In diesem Ausführungsbeispiel weisen die Ziegel 19 eine wellenförmige Oberfläche auf, an die sich das geschmeidige Mehrlagenelement 10 derart anlegt, daß eine Abdichtung des Firstbereiches gegenüber Regen und Schnee gewährleistet ist. In die Vertiefungen zwischen zwei Wellenbergen des Ziegels 19, den sogenannten Wellentälern, legen sich die durch einen Ein- oder Freischnitt erzeugten Streifen 43 der einzelnen Lagen dicht aneinander und an die Oberfläche des Ziegels 19 an, während sie sich auf den Wellenbergen des Ziegels voneinander beabstanden, das heißt, der Zwischenraum zwischen zwei Streifen ist vergrößert. Von den Lagen des Mehrlagenelementes 10 ist in Figur 4 lediglich die obere Lage 31 erkennbar. Dadurch, daß das Mehrlagenelement mehrere übereinanderliegende Lagen aufweist, werden die durch das Anlegen der Lagen an die Oberfläche des Ziegels 19 gebildeten Zwischenräume zwischen den Streifen durch die darunterliegende Lage beziehungsweise Lagen abgedichtet. Bei einem anderen Ausführungsbeispiel können die Ziegel 19 eine andere Oberflächenform aufweisen, an die sich das Mehrlagenelement 10 in geeigneter Art und Weise anlegt. Unabhängig von der Ausführungsform der Ziegel 19 wird durch das Lüftungselement 1 die gewünschte Abdichtung gegenüber Regen und Schnee oder dergleichen und eine Luftzirkulation im Firstbereich des Daches hergestellt. In Figur 4 ist die aus dem First des Daches austretende Luft mit Pfeilen angedeutet.Figure 4 shows the perspective view Ridge area of the roof according to Figure 1. In this Exemplary embodiment, the bricks 19 have a wavy shape Surface on which the smooth Multilayer element 10 creates such that sealing the ridge area against rain and snow is guaranteed. In the wells between two wave crests of brick 19, the so-called Wave valleys, lay through one One or free cut produced strips 43 of the individual layers close to each other and to the surface of the brick 19 while they are on the Spacing the wave crests of the brick, that is, the space between two strips is enlarged. From the layers of the multilayer element 10 is only the upper layer 31 in FIG. 4 recognizable.

Das Mehrlagenelement 10 ist hier als sogenannte Einzugsdichtungsleiste ausgebildet. Bei Betrachtung der Figur 9 wird deutlich, daß die Streifen 43 der einzelnen Lagen versetzt zueinander angeordnet sind, wodurch bei einem Anliegen der einzelnen Streifen an eine Vertiefung oder eine Erhebung eines Ziegels die Zwischenräume zwischen zwei Streifen einer Lage durch ein oder mehrere Streifen einer darunterliegende Lage abgedeckt werden, wodurch der Firstbereich des Daches gegen den Eintrag von Flugschnee und Schlagregen abgedichtet ist. Gleichzeitig ist eine Luftzirkulierung -wie vorstehend bereits beschrieben- gegeben. Durch die unterschiedlichen Längen der Lagen kann das homogene Anliegen des Mehrlagenelements an das Bedachungsmaterial vorteilhaft beeinflußt werden, wobei durch die abgestuften Längen zusätzlich Material eingespart wird.Figure 9 shows a perspective view of the Multi-layer element 10 according to FIG. 8. The layers 31, 33 and 35 are on their long side 37 by means of a Clamping rail 51 connected to each other, the Multi-layer element 10 or the clamping rail 10 in a recording of the ceiling wall 5 of the Fan cap 3 can be inserted. The multi-layer element 10 is here as a so-called pull-in sealing strip educated. Looking at the figure 9 it is clear that the strips 43 of each Layers are arranged offset from each other, whereby if the individual strips are in contact with one Deepening or raising a brick the Spaces between two strips of a layer through one or more strips of an underlying one Location will be covered, creating the ridge area of the roof against the entry of flying snow and driving rain is sealed. At the same time an air circulation - as already described above - given. Because of the different Length of the layers can be the homogeneous concern of the Multi-layer element to the roofing material advantageous be influenced, being graded by the Lengths of additional material is saved.

Figur 10 zeigt eine perspektivische Darstellung einer weiteren Ausführungsform des Mehrlagenelementes 10 (obere Abbildung) und eine Draufsicht auf die einzelnen Lagen (untere Abbildung). Das in Figur 10 abgebildete Mehrlagenelement unterscheidet sich von dem in Figur 7 lediglich dadurch, daß die Streifen der einzelnen Lagen unterschiedliche Breiten aufweisen. Die Breite B3 der Streifen der oberen Lage 31 ist geringer als die Breite B2 der Streifen der mittleren Lage 33, wobei deren Breite B2 geringer ist als die Breite B1 der Streifen der unteren Lage 35. Die Lagen 31, 33 und 35 sind an ihrer Längsseite 37 mittels der Klemmschiene 51 miteinander verbunden.Figure 10 shows a perspective view of a another embodiment of the multilayer element 10 (top illustration) and a top view of the individual layers (lower figure). That in Figure 10 Multi-layer element shown differs from that in Figure 7 only in that the strips of the individual layers have different widths. The width B3 of the strips of the top layer 31 is less than the width B2 of the strips of middle layer 33, the width B2 being smaller is the width B1 of the strips of the bottom layer 35. The layers 31, 33 and 35 are on their long sides 37 with each other by means of the clamping rail 51 connected.

Die Figur 11 zeigt das Lüftungselement gemäß Figur 6 in zusammengerolltem Zustand. Durch die kompakte Form des Lüftungselements ist es möglich, es ohne besonderen Aufwand zu befördern. Damit wird der Transport des Lüftungselementes wesentlich vereinfacht.FIG. 11 shows the ventilation element according to FIG 6 rolled up. Due to the compact Shape of the ventilation element, it is possible without it to carry special effort. With that the Transport of the ventilation element significantly simplified.

Das Abdichtorgan 7 kann bei einer Lüfterkappe 3, die einstückig ausgebildet ist, eine geringere Materialdicke aufweisen, als die Deckenwand 5. Dadurch wird einerseits die Lüfterkappe 3 in dem Bereich verstärkt, in dem diese auf der Firstlatte 15 aufliegt, und das Abdichtorgan 7 behält andererseits seine Elastizität. Eine weitere Ausführungsform des erfindungsgemäßen Lüftungselements zeichnet sich dadurch aus, daß das Lüftungselement aus mehreren Materialien hergestellt ist. So kann beispielsweise die Deckenwand 5 aus Metall und das Abdichtvorgan 7 aus einem Kunststoff gefertigt sein. Es ist auch möglich, wenigstens eine Lage des als Mehrlagenelement 10 ausgebildeten Abdichtorgans aus Metall zu fertigen.The sealing member 7 can with a fan cap 3, which is formed in one piece, a smaller material thickness have than the ceiling wall 5. This on the one hand, the fan cap 3 in the area reinforced by this on the ridge 15 rests, and the sealing member 7 keeps on the other hand its elasticity. Another embodiment of the ventilation element according to the invention is characterized in that the ventilation element is made of several materials. For example the ceiling wall 5 made of metal and the sealing element 7 be made of a plastic. It is also possible to use at least one layer of the Multi-layer element 10 formed sealing member To manufacture metal.

Das als Mehrlagenelement ausgebildete Abdichtorgan 7 weist durch die Einschnitte 39 eine große Anpassungsfähigkeit an alle Bedachungsmaterialien auf. Weiterhin ist ein aus Kunststoff hergestelltes Mehrlagenelement 10 witterungsbeständig, wodurch seine Funktionalität auch nach langem Einsatz sichergestellt ist. Durch die übereinanderliegenden Lagen 31, 33 und 35 werden die durch das Anlegen der Streifen an das Bedachungsmaterial gebildeten Zwischenräume von der darunterliegenden Lage abgedichtet, wodurch der Eintrag von Regen und Schnee verhindert ist. Die Anzahl der Lagen des Mehrlagenelementes ist variabel und kann auch mehr als drei betragen. Ein Mehrlagenelement mit weniger als drei Lagen geht aus Figur 5c hervor. Das Mehrlagenelement wird auch als Mehrlagenlappen, Mehrlagen-Dichtungsband, Mehrlagen-Dichtungsstreifen, Mehrlagen-Fächerdichtung, Mehrlagen-Schuppendichtung und Mehrschnittlage bezeichnet.The sealing element designed as a multilayer element 7 has great adaptability due to the incisions 39 on all roofing materials. Furthermore, one is made of plastic Multi-layer element 10 weatherproof, whereby its functionality is guaranteed even after long use is. Through the superimposed Layers 31, 33 and 35 are the result of the mooring the strip formed on the roofing material Gaps sealed from the underlying layer, causing the entry of rain and snow is prevented. The number of layers of the multilayer element is variable and can be more than three be. A multi-layer element with less than three Layers are shown in Figure 5c. The multi-layer element is also used as a multi-layer flap, multi-layer sealing tape, Multi-layer sealing strips, multi-layer compartment seal, Multi-layer scale seal and Designated multi-cut position.

Das Lüftungselement weist weiterhin den Vorteil auf, daß die Abdichtorgane mit dem Bedachungsmaterial nicht verklebt werden müssen, so daß das Lüftungselement bei jeder Witterung problemlos verlegbar ist. Dennoch ist, aufgrund der Anlage durch das Eigengewicht der Abdichtorgane an das Bedachungsmaterial ein guter Andruck und somit ein sicheres Abdichten des First- und Walmbereich des Daches gewährleistet. Dadurch, daß keine Vorbereitungsarbeiten für den Klebevorgang ausgeführt werden müssen, beispielsweise Reinigen des Bedachungsmaterials von Staub, Materialrückständen oder dergleichen, und daß das Anpressen der angeklebten Abdichtorgane entfällt, sind die Kosten für eine Dacheindeckung reduziert.The ventilation element also has the advantage on that the sealing elements with the roofing material do not need to be glued so that the ventilation element easy to lay in any weather is. Nevertheless, due to the attachment by the Dead weight of the sealing elements on the roofing material a good pressure and thus a secure seal the ridge and hip area of the roof. Because no preparatory work must be carried out for the gluing process, for example cleaning the roofing material from Dust, material residues or the like, and that the pressing of the glued sealing elements omitted, are the costs for a roof covering reduced.
