- the sealing lip 16 can additionally be glued to the edge 13.
- the sealing lip 16 clings closely to the surface contour of the roof covering elements, regardless of whether the edge region is adapted to the surface contour of the roof covering elements is or not.
- the sealing lip 16 designed as a brush or its individual brush threads has or have a sufficiently high stability in order not to be lifted off the surface of the roof covering elements even in strong winds.
- the sealing lip 16 can be made of plastic or rubber.

Abstract
Description
Die Erfindung betrifft eine Lüfterkappe für First- und Gratabdeckungen, insbesondere aus Kunststoffmaterial, mit Luftdurchlaßöffnungen, mit einem Randbereich und mit einer im Randbereich vorgesehenen, sich an die Oberfläche von Dacheindeckungselementen anschmiegenden flexiblen Dichtlippe.The invention relates to a fan cap for ridge and ridge covers, in particular made of plastic material, with air passage openings, with an edge area and with a flexible sealing lip provided in the edge area and adhering to the surface of roofing elements.
Es ist bekannt, Dachabdeckungen zu hinterlüften, um mögliche Schädigungen durch Feuchtebildung zu vermeiden. Zu diesem Zwecke werden u. a. Lüfterkappen verwendet, die an ihrem Randbereich mit einem Abdichtelement versehen sind, um auf der Oberfläche der Dacheindeckungselemente, also in der Regel der Firstanschlußziegel, abzudichten. Zur Erzielung einer wirksamen Hinterlüftung wird im First- oder Gratbereich ein Unterdruck mit Hilfe der Lüfterkappen erzeugt. Durch den erzeugten Unterdruck wird die im Dachinnenraum vorhandene Luft abgesaugt und es tritt auf diese Weise eine wirksame Hinterlüftung ein.It is known to ventilate roof covers in order to avoid possible damage caused by moisture formation. For this purpose u. a. Fan caps are used, which are provided at their edge area with a sealing element in order to seal on the surface of the roof covering elements, that is to say usually the ridge connecting tiles. To achieve effective rear ventilation, negative pressure is generated in the ridge or ridge area with the help of the fan caps. Due to the negative pressure generated, the air present in the interior of the roof is sucked out and effective rear ventilation occurs.
Bei Lüfterkappen der vorgenannten Art tritt jedoch häufig das Problem auf, daß aufgrund von Herstellungstoleranzen, ungleichmäßiger Verlegung der Dacheindekkungselemente und scharfkantigen Übergängen im Spaltbereich zwischen der Lüfterkappe und den Dacheindeckungselementen der Randbereich der Lüfterkappe, also das Abdichtelement, nicht vollständig an den Dacheindeckungselementen abdichtet, so daß Spalte zwischen den Dacheindeckungselementen und der Lüfterkappe entstehen, durch die Feuchtigkeit und Schmutz in den Dachinnenraum eingetrieben werden können, wodurch der Dachstuhl beschädigt und der Dachinnenraum verschmutzt werden kann. Außerdem beeinträchtigen diese Spalte die zur Unterdruckerzeugung notwendige und erforderliche Abdichtung, wodurch die erwünschte Saugwirkung der Lüfterkappe und die Wirksamkeit der Ent- bzw. Hinterlüftung herabgesetzt wird.With fan caps of the aforementioned type, however, the problem often arises that, due to manufacturing tolerances, uneven laying of the roof covering elements and sharp-edged transitions in the gap area between the fan cap and the roof covering elements, the edge region of the fan cap, that is to say the sealing element, does not seal completely against the roof covering elements, so that There are gaps between the roof covering elements and the fan cap, through which moisture and dirt can be driven into the roof interior, which can damage the roof truss and contaminate the roof interior. In addition, these gaps affect the sealing necessary and necessary for the generation of negative pressure, as a result of which the desired suction effect of the fan cap and the effectiveness of the ventilation or rear ventilation are reduced.
Eine Lüfterkappe, von der die Erfindung ausgeht, ist aus der EP - A - 0 117 391 bekannt. Dort ist eine First- oder Gratabdeckung für mit Dacheindeckungsplatten eingedeckte Dächer beschrieben, wobei im Randbereich der First- oder Gratabdeckung ein Abdichtelement vorgesehen ist, das aus einem kammartigen Randteil aus elastisch verformbarem Material besteht, dessen Zähne mit einem die Zahnlücken überbrückenden Randstreifen aus flexiblem Material auseinanderspreizbar verbunden sind. Der flexible Randstreifen ist hierbei wellenförmig ausgebildet und mit Wellenbergen an den Zähnen des kammartigen Randteils befestigt. Weiterhin ist vorgesehen, daß sowohl der kammartige Randteil, als auch der Randstreifen aus einem witterungs- und alterungsbeständigen Kunststoff besteht.A fan cap, from which the invention is based, is known from EP-A-0 117 391. There a ridge or ridge cover is described for roofs covered with roof covering panels, a sealing element being provided in the edge region of the ridge or ridge cover, which consists of a comb-like edge part made of elastically deformable material, the teeth of which can be spread apart with an edge strip bridging the tooth gaps made of flexible material are connected. The flexible edge strip is wavy trained and attached to the teeth of the comb-like edge part with wave crests. Furthermore, it is provided that both the comb-like edge part and the edge strip consist of a weather-resistant and aging-resistant plastic.
Um bei dieser bekannten First- oder Gratabdeckung einen bestimmten Unterdruck und damit eine ausreichende Hinterlüftung erzielen zu können, ist es unbedingt erforderlich, daß eine gute Abdichtung an den Firstanschlußziegeln erreicht wird. Allerdings kann es aufgrund der wellenförmigen Ausbildung des flexiblen Randstreifens dazu kommen, daß sich zwischen der abzudichtenden Oberfläche der Firstanschlußziegel und dem Abdichtelement kleine Spalte oder Öffnungen ausbilden, wenn sich Zähne im montierten Zustand der First- oder Gratabdeckung auf die Wellentäler legen oder die Wellentäler im Abdichtzustand hochgedrückt werden und eine nach oben hin gerichtete Auswölbung bilden. Es versteht sich, daß derartige Undichtigkeiten nicht nur zu einem Flugschnee- und/oder Regeneintrag sowie dem Eintritt von Schmutz führen, sondern auch eine Unterdruckerzeugung wesentlich beeinträchtigen können. Ein weiterer Nachteil des Abdichtselements der bekannten Lüfterkappe besteht darin, daß das Abdichtelement nicht ohne weiteres und insbesondere unter Beeinträchtigung der Strömungsdichtheit unterschiedlichsten Spaltformen zwischen Lüfterkappe und Dacheindeckungselementen angepaßt werden kann, insbesondere bei abrupten und besonders ausgeprägten Spaltübergängen zwischen Lüfterkappe und Dacheindeckungselementen.In order to be able to achieve a certain negative pressure and thus adequate rear ventilation with this known ridge or ridge cover, it is imperative that a good seal is achieved on the ridge connection tiles. However, due to the wave-shaped design of the flexible edge strip, small gaps or openings can form between the surface of the ridge connection tile to be sealed and the sealing element when teeth lie on the wave troughs in the assembled state of the ridge or ridge cover or the wave troughs in the seal state be pushed up and form an upward bulge. It goes without saying that such leaks not only lead to the inflow of snow and / or rain and the entry of dirt, but can also significantly impair the generation of negative pressure. Another disadvantage of the sealing element of the known fan cap is that the sealing element cannot be adapted easily and in particular with a variety of gap shapes between the fan cap and roof covering elements, particularly when the flow tightness is impaired, especially in the case of abrupt and particularly pronounced gap transitions between fan cap and roof covering elements.
Aus der DE - A - 2 256 675 ist bereits eine Entlüftungsfirstkappe bekannt, die mit der eingangs genannten vergleichbar ist. Die bekannte Entlüftungsfirstkappe ist mit einem Befestigungsbereich und dachseitig mit im Randbereich angebrachten, sich über die Kappenlänge erstreckenden, elastisch nachgiebigen Abdichtorganen in Form von Dichtungslippen versehen. In den Dichtungslippen sind Ausnehmungen für Dachziegel vorgesehen. Die Ausnehmungen haben zum Teil ein fischschuppenartige Ausbildung. Die bekannte Entlüftungsfirstkappe ist allerdings nur für einen ganz bestimmten Dachziegeltyp geeignet. Darüberhinaus können nicht vorgesehene Spaltübergänge zwischen der Lüfterkappe und den Dachziegeln nicht ausgeglichen werden, so daß die erzielte Dichtwirkung in diesem Falle gering ist. Gleiches gilt im übrigen für die aus der DE - A - 2 262 924 bekannte Firstkappenanordnung, die im wesentlichen der zuvor genannten Entlüftungsfirstkappe entspricht.From DE-A-2 256 675 a vent ridge cap is already known which is comparable to the one mentioned at the beginning. The known vent ridge cap is provided with a fastening area and on the roof side with elastically flexible sealing elements in the form of sealing lips which are arranged in the edge area and extend over the length of the cap. Recesses for roof tiles are provided in the sealing lips. Some of the recesses have a fish scale-like formation. The well-known vent ridge cap is only suitable for a specific type of roof tile. In addition, not provided gap transitions between the fan cap and the roof tiles can not be compensated, so that the sealing effect achieved is low in this case. The same applies, moreover, to the ridge cap arrangement known from DE-A-2 262 924, which essentially corresponds to the ventilation ridge cap mentioned above.
Aufgabe der Erfindung ist es, eine Lüfterkappe der eingangs genannten Art derart weiterzubilden, daß auf einfache und zuverlässige Weise der Eintritt von Schmutz, Feuchtigkeit und Falschwinden zwischen der Lüfterkappe und den Dacheindeckungselementen verhindert und eine für eine ausreichende Hinterlüftung notwendige Unterdruckerzeugung ermöglicht wird.The object of the invention is to develop a fan cap of the type mentioned in such a way that the entry of dirt, moisture and false winds between the fan cap and the roof covering elements is prevented in a simple and reliable manner and the necessary negative pressure generation for sufficient rear ventilation is made possible.
Diese Aufgabe wird bei einer Lüfterkappe der eingangs genannten Art erfindungsgemäß im wesentlichen dadurch gelöst, daß die Dichtlippe aus einer das Eintreten von Falschwinden zwischen der Lüfterkappe und den Dacheindeckungselementen verhindernden Bürste besteht. Durch die Verwendung einer als Bürste ausgebildeten Dichtlippe im Randbereich der Lüfterkappe wird auf einfache Weise eine außerordentlich gute und sichere Abdichtung zwischen der Lüfterkappe und den Dacheindeckungselementen auch bei großen Herstellungstoleranzen oder bei ungenauem Verlegen der Dacheindeckungselemente erreicht, so daß das Eindringen von Feuchtigkeit und Schmutz verhindert und eine enorme Saugleistung und Ent- bzw. Hinterlüftungswirkung der Lüfterkappe erzielt wird.This object is achieved in a fan cap of the type mentioned in the present invention essentially in that the sealing lip consists of a brush preventing the occurrence of false winches between the fan cap and the roof covering elements. By using a sealing lip designed as a brush in the edge region of the fan cap, an extraordinarily good and secure seal between the fan cap and the roof covering elements is achieved in a simple manner even with large manufacturing tolerances or in the event of inaccurate laying of the roof covering elements, so that the penetration of moisture and dirt is prevented and enormous suction power and ventilation of the fan cap is achieved.

In den Fig. 1 und 2 ist eine Hälfte einer aus Kunststoff bestehenden Lüfterkappe 1 dargestellt. Die gesamte Lüfterkappe 1 umfaßt eine weitere, nicht dargestellte Hälfte, die symmetrisch zu der dargestellten Lüfterkappenhälfte verläuft. Es ist jedoch genauso gut möglich, daß die gesamte Lüfterkappe einteilig ausgeführt ist.1 and 2, one half of a
Die Lüfterkappe 1 umfaßt einen ebenen Firstlattenbefestigungsbereich 2, einen Entlüftungsbereich 3 und einen ebenen Randbereich 4. Der Firstlattenbefestigungsbereich 2, der Entlüftungsbereich 3 und der ebene Randbereich 4 gehen jeweils über Knickstellen ineinander über, wobei die jeweils aneinandergrenzenden Bereiche miteinander einen stumpfen Winkel einschließen. In dem auch als Nagelleiste bezeichneten Firstlattenbefestigungsbereich 2 sind Nagellöcher 5 vorgesehen, um die Lüfterkappe 1 an einer nicht gezeigten First- oder Gratlatte zu befestigen.The
Der Entlüftungsbereich 3 weist eine Reihe von Luftdurchlaßöffnungen 6 auf, die durch firstziegelseitig offene Ausstülpungen 7 des Entlüftungsbereichs 3 gebildet werden. Zwischen den die Luftdurchlaßöffnungen 6 aufweisenden Ausstülpungen 7 und dem Randbereich 4 sind im Entlüftungsbereich 3 eine weitere Reihe von Ausstülpungen vorgesehen, die Auflagesockel 8 bilden, auf denen nicht dargestellte Firstziegel abgestützt werden. Die Firstziegel liegen dabei mit entsprechenden Stegen auf ebenen im wesentlichen rechteckigen oder quadratischen Auflageflächen 9 der Auflagesockel 8 auf. Die Form der Auflagesockel wird weiterhin jeweils durch vier ebene, zur Auflagefläche 9 schräg gestellte Seitenwände 10 bestimmt, wobei die Auflagesockel 8 so nahe an dem die Luftdurchlaßöffnungen 6 aufweisenden Ausstülpungen 7 angeordnet sind, daß die einander zugewandten Seitenwände der Ausstülpungen 7 und der Auflagesockel 8 miteinander einen V-förmigen Querschnitt aufweisen. Der Berührungspunkt dieser beiden Seitenwände liegt dabei deutlich oberhalb der Grundebene 12 des Entlüftungsbereichs 3. Es ist jedoch ebenfalls möglich, daß die Auflagesockel 8 eine andere, beispielsweise höckerartige oder kegelstumpfförmige Form haben. Die Auflagesockel 8 besitzen eine im Vergleich zu den Luftdurchlaßöffnungen 6, die im dargestellten Beispiel eine ovale bzw. langlochartige Form aufweisen, geringere Länge und sind in zweckmäßiger Weise mittig zu den Luftdurchlaßöffnungen 6 bzw. den Ausstülpungen 7 angeordnet.The
Der Randbereich 4 ist durch einen äußeren Rand 13 begrenzt. Der Randbereich 4 kann dabei abwechselnd durch halbkreisförmige Aussparungen 14 und parallel zur Längsachse der Lüfterkappe 1 verlaufende gerade Abschnitte 15 begrenzt sein. Dies bietet sich besonders dann an, wenn der Rand 13 entsprechend der Oberflächenkontur von üblichen, nicht dargestellten Dacheindeckungselementen ausgebildet ist und auf diesen aufliegt.The
In jedem Falle ist es jedoch so, daß der Rand 13 über seine ganze Länge mit einer in der Ebene des Randbereichs 4 über den Rand 13 vorstehenden Dichtlippe 16 versehen ist, die in den Figuren nur schematisch dargestellt ist.In any case, however, the
Die Dichtlippe 16 besteht aus einer Bürste. Eine Bürste als Dichtlippe paßt sich problemfrei ohne Beeinträchtigung der Strömungsdichtheit den unterschiedlichsten Spaltformen zwischen der Lüfterkappe 1 und den Dacheindeckungselementen an, was insbesondere bei scharfkantigen Übergängen und/oder besonders ausgeprägten Spalterweiterungen wichtig ist.The sealing
Ferner ist es möglich, daß die Dichtlippe 16 mit einem im Querschnitt U-förmigen Halteabschnitt 18 auf den Rand 13 des Randbereichs 4 aufgeschoben wird. Der Abstand der Schenkel des Halteabschnitts 18 voneinander ist in diesem Fall zweckmäßigerweise etwas geringer als die Wandstärke des Randes 13, während die Schenkel des Halteabschnitts 18 ausreichend starr sind, so daß nach dem Aufschieben des Halteabschnitts 18 auf den Rand 13 die Dichtlippe 16 fest auf dem Rand 13 aufsitzt. Zur Erhöhung der Haltekraft kann die Dichtlippe 16 mit dem Rand 13 noch zusätzlich verklebt werden.Furthermore, it is possible for the
Aufgrund der Ausbildung als Bürste schmiegt sich die Dichtlippe 16 eng an die Oberflächenkontur der Dacheindeckungselemente an, und zwar unabhängig davon, ob der Randbereich der Oberflächenkontur der Dacheindeckungselemente angepaßt ist oder nicht. Die als Bürste ausgebildete Dichtlippe 16 bzw. ihre einzelnen Bürstenfäden weist bzw. weisen dabei eine genügend hohe Stabilität auf, um auch bei starken Winden von der Oberfläche der Dacheindeckunselemente nicht abgehoben zu werden.Due to the design as a brush, the
Die Dichtlippe 16 kann aus Kunststoff oder Gummi bestehen. Ferner ist es möglich, die Wandstärke des Randbereichs 4 im Bereich des Randes 13 geringer als in den übrigen Bereichen auszubilden, so daß einerseits durch das Anbringen der Dichtlippe 16 keine nennenswerte Verdickung auftritt und andererseits der Rand 13 der Lüfterkappe 1 auch eine gewisse Flexibilität aufweist, die das Anschmiegen der Lüfterkappe 1 an die Oberfläche der Dacheindeckungselemente verbessern kann.The
