Abstract

The coping ventilation device disclosed comprises an externally convex coping cover element (10), located externally and with a hole (11) in the region of the crown, and further comprising an insert (20) located in the cavity in the coping cover element to collect precipitation which enters and lead it back out. The insert consists of a central element (23) located at a given distance below the opening plus, staggered with respect to it, side elements (21, 22) which, for a given height of the central element, are located at a given distance from each other. Air passes from the space under the roof through this gap, is deflected sideways and passes between the side elements and the central element, whereupon it is deflected again over the central element before escaping through the opening in the cover element to the atmosphere. Conversely, precipitation which enters is deflected by the central part on to the side elements from where it passes into the cover element seating zone. The fact that the opening in the cover element has an upturned edge (12) creates a suction action. Alternatively, a spoiler cap can be mounted over the opening, thus producing a Venturi effect.

Description

Die Erfindung betrifft eine First-Entlüftungsvorrichtung, be­stehend aus einem außenseitigen, nach außen gewölbten, im Scheitelbereich mit einer Öffnung versehenen First-Deck­element und einem im Hohlraum des First-Deckelements ange­geordneten Einsatz zum Auffangen und nach außen Ableiten von eindringendem Niederschlag.The invention relates to a ridge ventilation device, consisting of an outside, curved outward, provided in the apex region with an opening ridge cover element and an insert arranged in the cavity of the ridge cover element for collecting and draining out of penetrating precipitation.

Derartige First-Entlüftungsvorrichtungen dienen dazu, in den Dachraum eindringende Luftfeuchtigkeit nach außen abzuführen. Außerdem sollen sie Wärme- und Kältestau-Bildung verhindern und bei starkem Wind einen Druckausgleich zwischen innen und außen herbeiführen.First venting devices of this type serve to discharge air moisture penetrating into the roof space to the outside. They are also intended to prevent the build-up of heat and cold and to equalize pressure between the inside and outside in strong winds.

Eine gattungsgemäße Vorrichtung ist aus der DE-OS 33 13 875 bekannt. Hierbei besteht der Einsatz aus zwei nach oben ge­wölbten und übereinanderliegenden Schalenelementen,die je­weils mit Luftdurchtrittsöffnungen versehen sind. Die Luft­durchtrittsöffnungen sind über die Wölbungsperipherie gesehen gegeneinander versetzt. Konstruktionsbedingt ist zugelassen, daß Niederschläge sowohl durch die Öffnungen der Außenschale als auch durch die Öffnungen im darunterliegenden Wölbungs­element eindringen. Sie werden erst durch das innerste, letzte Wölbungselement aufgefangen und abgeleitet. Es sind daher re­lativ viele Teile erforderlich. Außerdem können die mehrmali­gen Umlenkungen des Luftstroms dazu führen, daß der Luftaus­tausch nicht in der gewünschten Intensität erfolgt. Da das Außenelement mit seinen beiden Rändern auf Seitenflanschen ruht, die aus den Einsatzelementen hervorstehen und deren Ränder bilden, kann es zu einem Rückstau von Flüssigkeit kom­ men, insbesondere, weil Schmutz, Laub oder ähnliches diesen unter dem Gewichtsdruck des Außenelements stehenden, glei­chermaßen als Stütze und als Abfluß dienenden Bereich, ver­stopfen können.A generic device is known from DE-OS 33 13 875. The insert consists of two shell elements that are curved upwards and one above the other, each of which is provided with air passage openings. The air passage openings are offset from one another as seen over the bulge periphery. By design, it is permitted that precipitation penetrate both through the openings in the outer shell and through the openings in the arch element underneath. They are only caught and derived by the innermost, last arch element. A relatively large number of parts are therefore required. In addition, the repeated deflections of the air flow can result in the air exchange not taking place in the desired intensity. Since the outer element rests with its two edges on side flanges which protrude from the insert elements and form their edges, a backflow of liquid can occur men, in particular because dirt, leaves or the like can clog this under the weight pressure of the outer element, serving both as a support and as a drainage area.

Der Erfindung liegt die Aufgabe zugrunde, eine First-­Entlüftungsvorrichtung der eingangs genannten Art anzugeben, welche konstruktiv einfacher ausgebildet ist und dennoch einen ausreichend starken Luftaustausch gewährleistet.The invention has for its object to provide a ridge ventilation device of the type mentioned, which is structurally simpler and yet ensures a sufficiently strong air exchange.

Diese Aufgabe wird gemäß dem kennzeichnenden Teil des Haupt­anspruchs gelöst.This object is achieved in accordance with the characterizing part of the main claim.

Die Erfindung hat den Vorteil, daß die Umlenkung des Luftstroms auf ein Minimum reduziert wird und daß die Querschnittsflächen des Luftweges bezogen auf die Abmessungen der Entlüftungsvor­richtung relativ groß gehalten werden können. Es kann daher auch pro Entlüftungsvorrichtung eine entsprechend größere Dachfläche belüftet werden. Da darüber hinaus die Form des Einsatzes einfach und übersichtlich ausgestaltet ist, wird das Verlegen der Entlüftungsvorrichtung vereinfacht, so daß die Arbeitskosten beim Dachdecken gering gehalten werden kön­nen.The invention has the advantage that the deflection of the air flow is reduced to a minimum and that the cross-sectional areas of the air path can be kept relatively large in relation to the dimensions of the ventilation device. A correspondingly larger roof area can therefore also be ventilated for each ventilation device. In addition, since the shape of the insert is simple and clear, the laying of the ventilation device is simplified, so that the labor costs for roofing can be kept low.

Eine bevorzugte Weiterbildung der Erfindung besteht darin, daß die Öffnung des Außenelementes mit einer nach außen überste­henden Abrißkante versehen ist. Die Abrißkante bewirkt, daß ein am Dach entlang strömender Luftzug oberhalb der Öffnung einen Unterdruck erzeugt, so daß die Dachentlüftung durch die Saugwirkung unterstützt wird.A preferred development of the invention is that the opening of the outer element is provided with a tear-off edge protruding outwards. The tear-off edge has the effect that a draft flowing along the roof creates a negative pressure above the opening, so that the roof ventilation is supported by the suction effect.

Die Verwirbelung eines am Dach entlang streichenden Luftstroms und die Erzeugung eines Unterdruckbereichs wird noch dadurch verstärkt, daß parallel zu den in Längsrichtung verlaufenden Abrißkanten und unterhalb von diesen auf der Oberfläche des Außenelements jeweils eine weitere Abrißkante angeordnet ist.The swirling of an air stream sweeping along the roof and the generation of a vacuum area is further increased by the fact that a further tear-off edge is arranged parallel to the tear-off edges running in the longitudinal direction and below them on the surface of the outer element.

Diese weitere Abrißkante hat ferner den Vorteil, daß eine definierte, verstärkte Rippe vorhanden ist, die während des Transports und der Lagerung als Auflage beim Stapeln derar­tiger Elemente dient. Das Gewicht der aufgestapelten Elemen­te wird daher kontrolliert jeweils über diese verstärkten Be­reiche nach unten abgeleitet, so daß die Bruchgefahr verrin­gert wird.This further tear-off edge also has the advantage that a defined, reinforced rib is present, which serves as a support during stacking of such elements during transport and storage. The weight of the stacked elements is therefore controlled downwards through these reinforced areas, so that the risk of breakage is reduced.

Es hat sich als besonders zweckmäßig erwiesen, daß korrespon­dierend mit den weiteren, rippenartigen Abrißkanten nach innen in den Hohlraum ragende Rippen vorhanden sind. Sie üben neben der definierten Gewichtsübertragung innerhalb eines Stapels noch weitere, für die Entlüftung relevanten Funktionen aus. Dabei schützen sie den Entlüftungskanal gegen Fremdluft, die zwischen den Längsrändern des Außenelements und den zugehöri­gen Dachplatten im Auflagebereich des Außenelements eindrin­gen könnte. Außerdem fixieren sie das Innenelement, bevor­zugt mit Hilfe eines elastischen, eine vorgegebene Vorspannung erzeugenden, Klappergeräusche vermeidenden Unterlageelements. Ein ausreichender Wasseraustritt wird durch unterseitige Aus­nehmungen in diesen Rippen erreicht.It has proven to be particularly expedient to have ribs projecting inward into the cavity corresponding to the further rib-like tear-off edges. In addition to the defined weight transfer within a stack, they also perform other functions relevant for ventilation. They protect the ventilation duct against external air that could penetrate between the longitudinal edges of the outer element and the associated roof panels in the contact area of the outer element. In addition, they fix the inner element, preferably with the aid of an elastic base element that generates a predetermined preload and prevents rattling noises. Adequate water outlet is achieved through recesses in these ribs on the underside.

Als besonders geeignet für die elastische Unterlage erweist sich ein Schaumstoffmaterial, wie es als Komprie-Dichtband bekannt ist. Dieses Material paßt sich an das Profil und die Oberfläche der zugehörigen Dachplatten an, ohne daß es in einem eigenen Bearbeitungsvorgang entsprechend ausgeformt werden muß. Es kann auch auf einfache Weise mit der Unterseite des Ein­schubs verklebt werden.A foam material, as is known as a Komprie sealing tape, has proven to be particularly suitable for the elastic underlay. This material adapts to the profile and the surface of the associated roof tiles without having to be shaped accordingly in a separate machining process. It can also be easily glued to the underside of the insert.

Für das Mittelteil des Einschubs erweist es sich herstellungs­technisch besonders einfach und aerodynamisch besonders wir­kungsvoll, daß es mit einer leichten Außenwölbung versehen ist. Eine zuverlässige Ableitung von Niederschlägen wird dadurch erreicht daß das Mittelteil mit einer Tropfkante versehen ist.For the middle part of the slide-in it proves to be particularly simple in terms of production technology and aerodynamically particularly effective that it is provided with a slight external curvature. Reliable drainage of precipitation is achieved in that the middle part is provided with a drip edge.

Gleichermaßen kann es zweckmäßig sein, die Außenränder der Seitenteile mit einer Tropfkante zu versehen, die darüber hin­aus den Vorteil hat, daß sie die lagegerechte Zuordnung des Einschubs zur elastischen Unterlage gewährleistet und ein Ein­dringen von Feuchtigkeit in die Unterlage verhindert.Similarly, it may be appropriate to provide the outer edges of the side parts with a drip edge, which also has the advantage that it ensures the correct assignment of the insert to the elastic base and prevents moisture from penetrating into the base.

Eine weitere Ausgestaltung der Erfindung besteht darin, daß die Innenränder der Seitenteile mit einem nach oben weisenden Kragen versehen sind, welcher auch im Falle von größeren Was­sermengen, beispielsweise bei einem Sturzregen, das Unterdach zuverlässig trockenhält. Im übrigen dienen die Tropfkanten und der Kragen auch zur Längsversteifung des Einschubs.A further embodiment of the invention is that the inner edges of the side parts are provided with an upward-pointing collar, which keeps the sub-roof reliably dry even in the case of large amounts of water, for example in the event of a downpour. In addition, the drip edges and the collar also serve to stiffen the insert lengthways.

Der Durchtrittsquerschnitt zwischen dem Mittelteil und den Sei­tenteilen wird am wenigstens dadurch beeinträchtigt, daß die Abstandshalter aus mindestens zwei querverlaufenden Rippen be­steht. Die Rippen verbinden darüber hinaus die beiden Seiten­teile untereinander, so daß insgesamt ein relativ steifer Kör­per gebildet wird.The passage cross section between the middle part and the side parts is at least impaired in that the spacer consists of at least two transverse ribs. The ribs also connect the two side parts to one another, so that overall a relatively rigid body is formed.

Zur weiteren Versteifung des Einsatzes ist es ferner vorteil­haft, daß auf der Oberseite des Mittelteils vertikale Querrippen vorhanden sind, die bis in den Bereich der Öffnung des Abdeckelementes reichen. Die Rippen haben ferner den Vorteil, daß sie ein Gitter bilden, welches das Eindringen von Laub, Kleintieren o.ä. verhindern. Ferner verhindern sie einen Schrägeinfall von Niederschlägen.To further stiffen the insert, it is also advantageous that vertical transverse ribs are present on the upper side of the central part, which extend into the area of the opening of the cover element. The ribs also have the advantage that they form a grid that prevents the ingress of leaves, small animals or the like. prevent. They also prevent precipitation from sloping.

In einer besonders bevorzugten alternativen Weiterbildung der Erfindung ist ein Spoilerelement, bestehend aus einer hori­zontal verlaufenden Spoilerkappe und vertikalen, auf den Ein­satz aufgesetzten Spoilerträgern vorhanden. Im montierten Zu­ stand befindet sich die Spoilerkappe oberhalb der Öffnung des Deckelements. Sie erzeugt einen Venturi-Effekt, durch wel­chen Luft aus dem Unterdach abgesaugt wird.In a particularly preferred alternative development of the invention, there is a spoiler element, consisting of a horizontally running spoiler cap and vertical spoiler carriers placed on the insert. In the assembled Zu the spoiler cap is located above the opening of the cover element. It creates a venturi effect, through which air is extracted from the sub-roof.

Nachfolgend wird die Erfindung anhand von zwei in der Zeichnung dargestellten Ausführungsformen weiter beschrieben.

In Fig. 1 ist mit 10 ein aus Ton gebranntes First Deckelement (Firstlüftungsziegel) bezeichnet. Es ist im Scheitelbereich mit einer in Längsrichtung verlaufenden, schlitzförmigen Öff­nung 11 versehen, die an allen Rändern mit einer nach oben vorstehenden Abrißkante 12 versehen ist. Das in Fig. 1 darge­stellte Beispiel weist ferner zwei weitere Abrißkanten 13, 13′ auf, die parallel zur Längsrichtung des Firstdeckelements 10 bzw. der Öffnung 11 in einem vorgegebenen Abstand von der Abrißkante 12 auf beiden Außenseiten des Firstdeckelements 10 verlaufen.In Fig. 1, 10 is a fired clay clay roof element (ridge ventilation tile). It is provided in the apex region with a slot-shaped opening 11 which runs in the longitudinal direction and is provided on all edges with a tear-off edge 12 which projects upwards. The example shown in FIG. 1 also has two further tear-off edges 13, 13 ', which run parallel to the longitudinal direction of the ridge cover element 10 or the opening 11 at a predetermined distance from the tear-off edge 12 on both outer sides of the ridge cover element 10.

Wie der Teilschnitt des Firstdeckelements 10 weiter veran­schaulicht, ist das Firstdeckelement mit zwei, in Längsrich­tung verlaufenden und im wesentlichen vertikal frei in den Hohlraum ragenden Stützrippen 14, 15 versehen. Sie befinden sich im wesentlichen unterhalb der weiteren Abrißkanten 13,13′, so daß beim Stapeln mehrerer derartiger Firstdeckelemente 10 die Stützrippen 14,15 mit den weiteren Abrißkanten des jeweils darunter liegenden Firstdeckelements in Eingriff gelangen und sich auf diesen abstützen. Innerhalb eines Stapels wird daher das Gewicht der Firstdeckelemente in dem durch die wei­teren Abrißkanten 13,13′ und Stützrippen 14,15 in dem betref­fenden Bereich aufgenommen und nach unten abgeleitet.As the partial section of the ridge cover element 10 further illustrates, the ridge cover element is provided with two support ribs 14, 15 which run in the longitudinal direction and project substantially vertically freely into the cavity. They are essentially below the further tear-off edges 13, 13 ′, so that when several such ridge cover elements 10 are stacked, the supporting ribs 14, 15 come into engagement with and are supported on the further tear-off edges of the ridge cover element below each. Within a stack, the weight of the ridge cover elements is therefore taken up in the area in question by the further tear-off edges 13, 13 'and supporting ribs 14, 15 and is derived downward.

Alternativ dazu ist es auch möglich, anstelle der weiteren Abrißkanten 13,13′ andere mit den Stützrippen 14,15 zusammen­wirkende punktförmige Auflager, wie sie bei 16 gestrichelt schematisch dargestellt sind, vorzusehen.Alternatively, it is also possible to provide other punctiform supports interacting with the supporting ribs 14, 15 instead of the further tear-off edges 13, 13 ', as schematically shown in dashed lines at 16.

Im Hohlraum desfirstdeckelements 10 ist ein aus Kunststoff hergestellter Einsatz 20 (Firsteinleger) vorhanden, welcher eine luftdurchlässige und Niederschläge abweisende Schikane dar­stellt. Die Länge des Einsatzes 20 kann mit der Länge des Firstdeckelemente 10 übereinstimmen. Bevorzugt ist sie jedoch ein ganzzahliges Vielfaches der Länge des Firstdeckelements 10. Der Einsatz 20 besteht aus zwei in Längsrichtung paralle­len, auf Abstand voneinander angeordneten Seitenteilen 21,22 sowie einem den Zwischenraum zwischen den Seitenteilen 21,22 in einem vorgegebenen Abstand überbrückenden Mittelteil 23. Das Mittelteil 23 und die beiden Seitenteile 21,22 sind im we­sentlichen an den Stirnseiten über querrippenbildende Abstands­halter 24 miteinander verbunden. Bei längeren Einsätzen 20 sind über die Länge verteilt mehrere derartige Abstandshalter 24′ vorhanden. Seitlich befinden sich jeweils zwischen den Seitenteilen 21 bzw. 22 und dem Mittelteil 23 Öffnungen 25 bzw. 26 als Luftdurchlaß. Die Seitenteile 21,22 liegen stufen­oder schulterartig seitlich unterhalb des Mittelteils 23. Mehrere Einsätze 20 sind stirnseitig in der Weise ineinander einschiebbar, daß eine Stirnseite eines jeden Einsatzes 20 offen ist (nicht dargestellt), d.h.daß der betreffende stirn­seitige Abstandshalter 24 entfernt ist.In the cavity of the first cover element 10 there is an insert 20 made of plastic (first layer insert), which is an air-permeable and precipitation-resistant chicane. The length of the insert 20 can match the length of the ridge cover element 10. However, it is preferably an integer multiple of the length of the ridge cover element 10. The insert 20 consists of two longitudinally parallel, spaced-apart side parts 21, 22 and a central part 23 bridging the space between the side parts 21, 22 at a predetermined distance The middle part 23 and the two side parts 21, 22 are essentially connected to one another at the end faces by means of spacers 24 which form transverse ribs. For longer missions 20 there are several such spacers 24 'distributed over the length. On the side, there are openings 25 and 26 between the side parts 21 and 22 and the middle part 23 as air passages. The side parts 21, 22 lie stepwise or shoulder-like laterally below the middle part 23. A plurality of inserts 20 can be inserted into one another at the end side in such a way that one end side of each insert 20 is open (not shown), ie that the end spacer 24 in question is removed.

Die Fig. 1 veranschaulicht ferner zwei Leitflächen 42,43, Aus­nehmungen 18 in den Stützrippen sowie teilweise einen Rippen einsatz 46.1 further illustrates two guide surfaces 42, 43, recesses 18 in the supporting ribs and partially a rib insert 46.

Wie Fig. 2 veranschaulicht, sind auf die beiden obersten senk­recht zur Zeichenebene ausgerichteten Dachlatten 30,31 Dach­ziegel 32,33 aufgelegt. Zwischen den oberen Enden der Dachzie­gel 32,33 befindet sich ein Durchlaßspalt 34 zur Entlüftung des Dachraums 35. Entlang der Ränder der Dachziegel 32,33 sowie daran anstoßender Dachziegel (nicht dargestellt) befindet sich jeweils eine streifenförmige, elastische Schaumstoffunterlage 36,37, die als Komprie-Dichtband bekannt ist. Auf diesen bei­den Unterlagen 36,37 liegt der Einsatz 20 mit seinen Seiten­teilen 21,22 auf. Da sich die Unterlagen 36,37 an die Außen­kontur der Dachziegel 32,33 anpassen, wird ein formschlüssiger, im wesentlichen luftdichter Abschluß zwischen den Dachziegeln 32,33 und dem Einsatz 20 erreicht.As illustrated in FIG. 2, roof tiles 32, 33 are placed on the two uppermost roof battens 30, 31 oriented perpendicular to the plane of the drawing. Between the upper ends of the roof tiles 32,33 there is a passage gap 34 for venting the roof space 35. Along the edges of the roof tiles 32,33 and adjoining roof tiles (not shown) there is a strip-shaped, elastic foam underlay 36,37, which as Komprie sealing tape is known. The insert 20 with its side parts 21, 22 rests on these two documents 36, 37. Since the documents 36, 37 adapt to the outer contour of the roof tiles 32, 33, a form-fitting, essentially airtight seal between the roof tiles 32, 33 and the insert 20 is achieved.

Von oben drücken die Stützrippen 14,15 des Firstdeckelements 10 auf die von den Unterlagen 36,37 unterstützten Bereiche der Seitenteile 21,22. Der Einsatz 20 ist mit den Unterlagen 36,37 verklebt. Insgesamt ist das Firstdeckelement 10 jedoch nicht auf den Unterlagen 36,37 gelagert, sondern es liegt mit seinem unteren Rand 17 auf den Dachziegeln 32,33 auf. Es kann mittels den querverlaufenden Rippen 44, die über den Rand der Öffnung 11 übergreifen, am Mittelteil 23 fixiert werden. Der Rippen­einsatz 46 in dem wiedergegebenen Beispiel ist lösbar auf den Einsatz 20 befestigt. Zu diesem Zweck befindet sich auf dem Mittelteil 23′ eine durchgehende Rastnase 55 oder Rastpunkte, welche von Fingern 56 an den Stützen 52 federnd hintergriffen wird/werden. Die Stützen 52 (Fig. 3) können, ebenso wie die Rippen 44, ein Schutzgitter gegen Laubwerk, Vögel etc. bilden.From above, the supporting ribs 14, 15 of the ridge cover element 10 press onto the areas of the side parts 21, 22 supported by the documents 36, 37. The insert 20 is glued to the documents 36, 37. Overall, however, the ridge cover element 10 is not supported on the documents 36, 37, but lies with its lower edge 17 on the roof tiles 32, 33. It can be fixed to the central part 23 by means of the transverse ribs 44 which extend over the edge of the opening 11. The rib insert 46 in the example shown is releasably attached to the insert 20. For this purpose, there is a continuous locking lug 55 or locking points on the central part 23 ', which is / are spring-loaded behind by fingers 56 on the supports 52. The supports 52 (FIG. 3), like the ribs 44, can form a protective grid against leaves, birds, etc.

Die Stützen 52 und die Rippen 44 fixieren ferner das First­deckelement 10′ in seiner Lage. Die Querrippen 44 sind ober­halb der Rastnase mit einer Längsrippe 45 miteinander verbun­ den, deren Höhe so bemessen ist, daß sie den Luftstrom nicht behindert.The supports 52 and the ribs 44 also fix the ridge deck element 10 'in its position. The transverse ribs 44 are connected to one another above the latching lug with a longitudinal rib 45 the height of which is such that it does not obstruct the air flow.

Das Mittelteil 23 des Einsatzes 20 ist genau unterhalb der Öffnung 11 des Firstabdeckelementes 10 und in einem vorgegebe­nen Abstand von der Innenseite des Firstdeckelementes 10 ange­ordnet. Es ist mit einer leichten Außenwölbung und mit einem Überstand über die beiden Seitenteile 21,22 versehen, so daß eindringender Niederschlag auf die Seitenteile 21,22 abfließt. Vorsorglich sind entlang der Ränder des Mittelteils 23 Tropf­kanten 27 angeformt. Außerdem sind die darunter liegenden Rän­der der beiden Seitenteile 21,22 mit einem Kragen 28 versehen, der verhindert, daß Regenwasser in den Zwischenraum 38 zwi­schen den beiden Seitenteilen 21,22 fließen kann. Zum zuver­lässigen Ableiten von Niederschlägen sind die Seitenteile 21, 22 mit einer leichten Außenneigung versehen. Der Abfluß er­folgt im wesentlichen durch unten offene Ausnehmungen 18 im Auflagebereich der Stützrippen 14,15. Das Mittelteil 23 ist im wesentlichen auf Lücke zur Öffnung 11 angeordnet. Die beiden Seitenteile 21,22 enden an ihren Außenseiten in nach unten abgekröpften Tropfkanten 29, welche die Unterlagen 36,37 seitlich übergreifen.The middle part 23 of the insert 20 is arranged exactly below the opening 11 of the ridge cover element 10 and at a predetermined distance from the inside of the ridge cover element 10. It is provided with a slight outer curvature and with a protrusion over the two side parts 21, 22 so that penetrating precipitation flows onto the side parts 21, 22. As a precaution, drip edges 27 are formed along the edges of the middle part 23. In addition, the underlying edges of the two side parts 21, 22 are provided with a collar 28 which prevents rain water from flowing into the space 38 between the two side parts 21, 22. For reliable drainage of precipitation, the side parts 21, 22 are provided with a slight external inclination. The drainage takes place essentially through recesses 18 open at the bottom in the contact area of the support ribs 14, 15. The middle part 23 is arranged essentially at a gap to the opening 11. The two side parts 21, 22 end on their outer sides in drip edges 29 bent downwards, which laterally overlap the documents 36, 37.

Nachfolgend wird die Funktion dieser Firstentlüftungsvorrich­tung beschrieben. Luft aus dem Dachraum 35 gelangt über die Durchlaßspalte 34 und den darüber liegenden Zwischenraum 38 zum Mittelteil 23, wo sie seitlich abgelenkt und über die Öff­nungen 25,26 gemäß Pfeilen 39 in den Durchlaß 40,41 zwischen dem Mittelteil 23 und dem Firstdeckelement 10 strömt. Von dort kann sie über die Öffnung 11 ungehindert nach außen ent­weichen.The function of this ridge ventilation device is described below. Air from the roof space 35 passes through the passage gaps 34 and the overlying space 38 to the middle part 23, where it is deflected laterally and flows through the openings 25, 26 according to arrows 39 into the passage 40, 41 between the middle part 23 and the ridge cover element 10. From there it can escape freely through the opening 11 to the outside.

Die Abrißkante 12 bewirkt ein Abreißen der Strömung der von außen über das Dach entlang streichenden Luftströmungen. Auf diese Weise entsteht eine Unterdruck-Saugwirkung, welche die Dachentlüftung unterstützt.The tear-off edge 12 tears off the flow of the air currents flowing along the roof from the outside. This creates a vacuum suction effect, which the Roof ventilation supported.

Um der Luftströmung in der Durchlaßspalte 34 möglichst wenig Widerstand entgegenzubringen, kann es zweckmäßig sein, am Ein­satz 20 nach unten reichende seitliche Leitflächen 42,43 vor­zusehen, die von den Innenrändern der Seitenteile 21,22 bis in den Bereich der Dachlatten 30,31 reichen (gestrichelt darge­stellt). Sie können auch zum Annageln oder Verschrauben des Einsatzes 20 an den Dachlatten 30,31 dienen.In order to provide as little resistance as possible to the air flow in the passage gap 34, it can be expedient to provide side guide surfaces 42, 43 which extend downward on the insert 20 and extend from the inner edges of the side parts 21, 22 to the area of the roof battens 30, 31 ( shown in dashed lines). They can also be used to nail or screw the insert 20 onto the roof battens 30, 31.

Bei dem in Fig. 3 dargestellten Ausführungsbeispiel sind glei­che Teile wie in Fig. 2 mit gleichen Bezugszeichen versehen, so daß auf die Beschreibungen im einzelnen verzichtet wird.In the embodiment shown in Fig. 3, the same parts as in Fig. 2 are given the same reference numerals, so that the descriptions are omitted in detail.

Das in Fig. 3 veranschaulichte Firtdeckelement 10′ unter­scheidet sich von demjenigen der Fig. 1 und 2 dadurch, daß entlang der Öffnung 11 keine Abrißkante vorhanden ist. Um eine erhöhte Saugwirkung zu erzeugen, ist auf das Mittelteil 23′ des Einsatzes 20′ eine aus Kunststoff gefertigte Spoilerkappe 50 aufgesetzt. Sie besteht aus einem nach unten gewölbten Spoi­ler 51 über der Öffnung 11 des Firstdeckelements 10′, wel­cher den Durchtrittsquerschnitt verengt, um eine Querströmung 53 zu beschleunigen. Es entsteht ein Venturi-Effekt, welcher gemäß Pfeil 54 Luft aus dem Dachraum absaugt.The Firtdeckelement 10 illustrated in FIG. 3 'differs from that of FIGS. 1 and 2 in that there is no tear-off edge along the opening 11. In order to produce an increased suction effect, a plastic spoiler cap 50 is placed on the middle part 23 'of the insert 20'. It consists of a downwardly curved spoiler 51 above the opening 11 of the ridge deck element 10 ', which narrows the passage cross section to accelerate a cross flow 53. A venturi effect is created, which draws air from the roof space according to arrow 54.

Der Spoiler 51 ist über Stützen 52, die in Richtung der Quer­strömung 53 ausgerichtet sind, in dem wiedergegebenen Beispiel lösbar auf dem Einsatz 20 befestigt, wie dies in Fig. 2 im Zusammenhang mit den Querrippen 44 beschrieben wurde.The spoiler 51 is detachably fastened on the insert 20 in the example shown via supports 52 which are aligned in the direction of the transverse flow 53, as was described in connection with the transverse ribs 44 in FIG. 2.
