Description

Die Erfindung betrifft eine Sauglüfterkappe für First- und Gratabdeckungen zur Dachentlüftung, insbesondere aus Kunststoffmaterial, mit einem Entlüftungsbereich und einem Randbereich, die vorzugsweise über Knickstellen ineinander übergehen, mit Luftdurchlaßöffnungen, die von firstziegelseitig offenen, vorzugsweise in Längsrichtung der Sauglüfterkappe ausgerichteten langlochartigen Ausstülpungen des Entlüftungsbereichs gebildet sind und über die die Luft abgesaugt wird, und mit einer im Randbereich vorgesehenen, sich zumindest über einen Teil seiner Länge erstrekkenden und sich an die Oberfläche der Dacheindeckungselemente anschmiegenden Dichtlippe.The invention relates to a suction fan cap for ridge and ridge covers for roof ventilation, in particular made of plastic material, with a ventilation area and an edge area, which preferably merge into one another via kinks, with air passage openings which are formed by slot-like protrusions of the ventilation area that are open on the ridge side, preferably aligned in the longitudinal direction of the suction fan cap are and through which the air is sucked off, and with a sealing lip provided in the edge region, extending at least over part of its length and adhering to the surface of the roof covering elements.

Es ist bekannt, Dachabdeckungen zu hinterlüften, um mögliche Schädigungen durch Feuchtebildung zu vermeiden. Die zu diesem Zwecke gebräuchlichen Sauglüfterkappen liegen mit einem entsprechend der Oberflächenkontur der anschließenden Dacheindeckungselemente geformten Randbereich auf diesen auf. Dabei entsteht jedoch häufig das Problem, daß aufgrund von Herstellungstoleranzen oder ungleichmäßiger Verlegung der Dacheindeckungselemente der Randbereich der Sauglüfterkappe nicht sauber mit den Dacheindeckungselementen abschließt, so daß Spalte entstehen, durch die Feuchtigkeit und Schmutz zwischen Dacheindeckungselementen und Sauglüfterkappe eingetrieben werden kann, wodurch der Dachstuhl beschädigt werden kann. Außerdem entstehen durch die Spalte Luftströmungsverhältnisse, die die erwünschte Saugwirkung der Sauglüfterkappe beeinträchtigen und dadurch die Wirksamkeit der Entlüftung herabsetzen.It is known to ventilate roof covers in order to avoid possible damage caused by moisture formation. The suction fan caps commonly used for this purpose rest on them with an edge area shaped according to the surface contour of the adjoining roof covering elements. However, this often creates the problem that, due to manufacturing tolerances or uneven laying of the roof covering elements, the edge region of the suction fan cap does not terminate properly with the roof covering elements, so that gaps are created through which moisture and dirt can be driven in between the roof covering elements and the suction fan cap, thereby damaging the roof truss can. In addition, the column creates air flow conditions that impair the desired suction effect of the suction fan cap and thereby reduce the effectiveness of the ventilation.

Eine Sauglüfterkappe der eingangs genannten Art ist bereits aus der EP - A-0117 391 bekannt. Bei der bekannten Sauglüfterkappe weist die Dichtlippe einen biegsamen Trägerstreifen auf, der kammartig ausgebildet ist, wobei die Zähne mit einem die Zahnlücken überbrückenden Randstreifen aus flexiblem Material auseinanderspreizbar verbunden sind. Aufgrund der "schwimmhautartigen" Ausbildung der Dichtlippe wird zwischen den Zähnen eine absolute Luftdichtigkeit erzielt. Probleme treten bei dieser bekannten Lüfterkappe aber immer dann auf, wenn zwischen benachbarten Dacheindeckungselementen große Spalte überbrückt werden müssen und auch die auseinandergezogene Dichtlippe derartige Spalte nicht hinreichend überbrücken kann, so daß sich zwangsläufig Undichtigkeiten ergeben. Weiterhin ergeben sich Undichtigkeiten aufgrund der Wellenform der Zähne und Randstreifen, da sich im Bereich der Zähne Kanäle bilden, die in den Dachinnenraum führen.A suction fan cap of the type mentioned is already known from EP - A-0117 391. In the known suction fan cap, the sealing lip has a flexible carrier strip which is designed like a comb, the teeth being connected to one another by a spreading edge strip bridging the tooth gaps and made of flexible material. Due to the "floating skin-like" design of the sealing lip, absolute airtightness is achieved between the teeth. Problems occur with this known fan cap, however, whenever large gaps have to be bridged between adjacent roof covering elements and the pulled-apart sealing lip cannot sufficiently bridge such gaps, so that there are necessarily leaks. Farther there are leaks due to the waveform of the teeth and edge strips, since channels form in the area of the teeth which lead into the roof interior.

Aus den DE - A - 22 56 675, DE - A - 22 62 924 und DE - A - 27 07 384 sind Lüfterkappen bekannt, bei denen dem Dachinnenraum Außenluft zugeführt wird. Im Gegensatz zu der zuvor genannten Sauglüfterkappe erfolgt also keine Entlüftung, sondern eine Belüftung.Fan caps are known from DE-A-22 56 675, DE-A-22 62 924 and DE-A-27 07 384, in which outside air is supplied to the roof interior. In contrast to the suction fan cap mentioned above, there is no ventilation, but ventilation.

Bei der aus der DE - A - 22 56 675 bekannten Lüfterkappe wird mit Hilfe von zwei Dichtungslippen und versetzt in den Dichtungslippen vorgesehenen Lüftungsöffnungen versucht, mitgerissenes Wasser, Flugschnee und Staub abzuscheiden, damit letztlich die in den Dachstuhl eintretende Luft praktisch frei von mitgerissenen Stoffen ist.In the fan cap known from DE-A-22 56 675, two sealing lips and offset ventilation openings provided in the sealing lips attempt to separate entrained water, flying snow and dust, so that ultimately the air entering the roof structure is practically free of entrained substances .

Die aus der DE - A - 22 62 924 bekannte Lüfterkappe funktioniert in ähnlicher Weise wie die zuvor beschriebene. Dort sind in den Entlüftungsteilen Prallwände vorgesehen, in denen sich Wasser und Flugschnee abscheiden soll.The fan cap known from DE-A-22 62 924 functions in a similar manner to that described above. There baffle walls are provided in the ventilation parts, in which water and flying snow should separate.

Schließlich sind bei der aus der DE - A - 27 07 384 bekannten Lüfterkappe im Randbereich seitliche Zungen vorgesehen, die über einen Abstand von 1 Millimeter voneinander beabstandet sind. Lüftungsöffnungen im eigentlichen Sinne sind nicht vorgesehen. Diese bekannte Lüfterkappe funktioniert derart, daß durch die Zungen zwar ein Schneeintrieb verhindert wird, gleichzeitig aber über die Spalte zwischen den Zungen eine Belüftung des Firstbereichs gewährleistet sein soll.Finally, in the case of the fan cap known from DE-A-27 07 384, lateral tongues are provided in the edge area, which are spaced apart by a distance of 1 millimeter. Ventilation openings in the actual sense are not provided. This known fan cap works in such a way that snow is prevented by the tongues, but at the same time ventilation of the ridge area is to be ensured via the gaps between the tongues.

Das gemeinsame Merkmal der zuvor genannten Lüfterkappen besteht darin, daß über den Randbereich eine Belüftung des Dachinnenraums erfolgt. Kleinere Undichtigkeiten spielen bei diesen Lüfterkappen keine große Rolle, so lange gewährleistet ist, daß Feuchtigkeit oder Schmutzpartikel nicht über diese Undichtigkeiten eindringen können.The common feature of the aforementioned fan caps is that the roof area is ventilated via the edge area. Smaller leaks do not play a major role in these fan caps, as long as it is ensured that moisture or dirt particles cannot penetrate through these leaks.

Der Erfindung liegt nun die Aufgabe zugrunde, eine Sauglüfterkappe der eingangs genannten Art zu schaffen, die auf einfache und zuverlässige Weise das Eintreten von Schmutz, Feuchtigkeit und Falschwinden zwischen der Sauglüfterkappe und den Dacheindeckungselementen verhindert.The invention is based on the object of providing a suction fan cap of the type mentioned at the outset which is easy and reliable to enter prevents dirt, moisture and false winds between the suction fan cap and the roof covering elements.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Randbereich entsprechend der Oberflächenkontur der Dacheindeckungselemente geformt ist und daß die Dichtlippe unmittelbar aneinanderliegende Lamellen aufweist, die jeweils nur durch in einem gleichmäßigen Abstand nebeneinanderliegende Einschnitte voneinander getrennt sind.This object is achieved in that the edge area is shaped according to the surface contour of the roofing elements and that the sealing lip has directly adjacent lamellae, which are separated from each other only by incisions lying next to one another at a uniform distance.

Durch die Anordnung der sich an die Oberflächenkontur der Dacheindeckungselemente anschmiegenden, die unmittelbar aneinanderliegenden lamellen aufweisenden Dichtlippe am Randbereich der Sauglüfterkappe wird auf einfache Weise eine zuverlässige Abdichtung zwischen der Sauglüfterkappe und den Dacheindeckungselementen auch bei großen Herstellungstoleranzen oder ungenauem Verlegen der Dacheindeckungselemente erreicht, so daß das Eindringen von Feuchtigkeit und Schmutz verhindert wird und die volle Saugleistung und Entlüftungswirkung der Sauglüfterkappe erhalten bleibt.Due to the arrangement of the sealing lip that clings to the surface contour of the roof covering elements and the immediately adjacent lamellar sealing lip on the edge region of the suction fan cap, a reliable seal between the suction fan cap and the roof covering elements is achieved in a simple manner even with large manufacturing tolerances or inaccurate laying of the roof covering elements, so that the penetration of moisture and dirt is prevented and the full suction power and ventilation effect of the suction fan cap is retained.

Gemäß einer vorteilhaften Ausführungsform der Erfindung besteht die Dichtlippe aus einem die eng aneinanderliegende Lamellen aufweisenden Lamellenband, welches an der oberen und/ oder unteren Oberfläche des Randbereichs befestigt, insbesondere aufgeklebt ist. Dieses Lamellenband kann beispielsweise eine stabile Kunststoffolie sein, welche in derselben Ebene, in der der Randbereich der Sauglüfterkappe liegt, über den Randbereich vorsteht und in der die Lamellen durch senkrecht zur längsachse der Sauglüfterkappe verlaufende Einschnitte gebildet werden.According to an advantageous embodiment of the invention, the sealing lip consists of a lamella band which has the closely spaced lamellae and which is fastened, in particular glued, to the upper and / or lower surface of the edge region. This lamella band can be, for example, a stable plastic film which projects beyond the edge region in the same plane in which the edge region of the suction fan cap lies and in which the lamellae are formed by incisions running perpendicular to the longitudinal axis of the suction fan cap.

Es ist jedoch auch möglich, die Dichtlippe integral mit dem Randbereich dadurch auszubilden, daß die Wandstärke des Randbereichs zu seinem Rand hin bis zur Wandstärke einer flexiblen Folie verringert wird. Eine derartige Dichtlippe ist einfach herzustellen und es erübrigen sich zusätzliche Montageschritte.However, it is also possible to form the sealing lip integrally with the edge region in that the wall thickness of the edge region is reduced towards its edge up to the wall thickness of a flexible film. Such a sealing lip is easy to manufacture and additional assembly steps are unnecessary.

Weitere vorteilhafte Ausführungsformen oder Ausführungsvarianten der Erfindung sind aus den Unteransprüchen ersichtlich.Further advantageous embodiments or design variants of the invention can be seen from the subclaims.

The invention is explained in more detail below, for example with reference to the drawing; it shows
Figure 1
a schematic representation of a fan cap half perpendicular to its longitudinal axis and
Figure 2
a cross-section along the arrows AA in Figure 1 on a somewhat enlarged scale.

In den Figuren 1 und 2 ist eine Hälfte einer aus Kunststoff bestehenden Sauglüfterkappe dargestellt. Die gesamte Sauglüfterkappe 1 umfaßt eine weitere, nicht dargestellte Hälfte, die symmetrisch zu der dargestellten Lüfterkappenhälfte verläuft. Es ist jedoch genausogut möglich, daß die gesamte Sauglüfterkappe 1 einteilig ausgeführt ist.In Figures 1 and 2, one half of a suction fan cap made of plastic is shown. The entire suction fan cap 1 comprises a further half, not shown, which runs symmetrically to the fan cap half shown. However, it is equally possible that the entire suction fan cap 1 is made in one piece.

Die Sauglüfterkappe 1 umfaßt einen ebenen Firstlattenbefestigungsbereich 2, einen Entlüftungsbereich 3 und einen ebenen Randbereich 4. Die einzelnen Bereiche gehen durch Knickstellen ineinander über, wobei die jeweils aneinander grenzenden Bereiche miteinander einen stumpfen Winkel einschließen.The suction fan cap 1 comprises a flat ridge fastening area 2, a ventilation area 3 and a flat edge area 4. The individual areas merge into one another by kinks, the areas adjoining each other enclosing an obtuse angle with one another.

In dem auch als Nagelleiste bezeichneten Firstlattenbefestigungsbereich 2 sind Nagellöcher 5 vorgesehen, um die Lüfterkappe an der First- oder Gratlatte zu befestigen.In the ridge fastening area 2, which is also referred to as a nail bar, nail holes 5 are provided in order to fasten the fan cap to the ridge or ridge slat.

Der Entlüftungsbereich 3 weist eine Reihe von Luftdurchlaßoffnungen 6 auf, die durch firstziegelseitig offene Ausstülpungen 7 des Entlüftungsbereichs 3 gebildet werden. Zwischen dem die Luftdurchlaßoffnungen 6 aufweisenden Ausstülpungen 7 und dem Randbereich 4 ist 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 und im wesentlichen rechteckigen oder quadratischen Auflageflächen 9 der Auflagesockel 8 auf. Die Form der Auflagesockel 8 wird weiterhin jeweils durch vier ebene, zur Auflagefläche 9 schräggestellte Seitenwände 10 bestimmt, wobei die Auflagesockel 8 so nahe an dem die Luftdurchlaßoffnungen 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, eine geringere Länge und sind in zweckmäßiger Weise mittig zu den Luftdurchlaßöffnungen 6 bzw. zu den Ausstülpungen 7 angeordnet.The ventilation area 3 has a series of air passage openings 6, which are formed by protuberances 7 of the ventilation area 3 that are open on the ridge tile side. A further row of protuberances is provided in the ventilation region 3 between the protuberances 7 having the air passage openings 6 and the edge region 4, which form support bases 8, on which ridge tiles, not shown, are supported. The ridge tiles lie with corresponding webs on flat and essentially rectangular or square support surfaces 9 of the support base 8. The shape of the support base 8 is further determined by four flat, to the support surface 9 inclined side walls 10 is determined, the support base 8 being so close to the protuberances 7 having the air passage openings 6 that the mutually facing side walls of the protuberances 7 and the support base 8 have a V-shaped cross section with one another. The point of contact of these two side walls lies clearly above the base plane 12 of the ventilation area 3. However, it is also possible for the support base 8 to have a different shape, for example a hump-like or frustoconical shape. The support bases 8 have a shorter length than the air passage openings 6, which in the example shown have an oval or slot-like shape, and are expediently arranged centrally to the air passage openings 6 or to the protuberances 7.

Der Randbereich 4 ist durch einen halbkreisförmige Aussparungen 14 und gerade Abschnitte 15 abwechselnd aufweisenden Rand 13 begrenzt, der entsprechend der Oberflächenkontur von üblichen, nicht dargestellten Dacheindeckungselementen ausgebildet ist und auf diesen aufliegt. Der Rand 13 ist über seine ganze Länge mit einer in der Ebene des Randbereichs 4 über den Rand 13 vorstehenden lamellenartigen Dichtlippe 16 versehen, die in Figur 1 nur schematisch dargestellt ist. Diese Dichtlippe 16 kann aus zwei, auf der Ober- und Unterseite des Randbereichs 4 aufgeklebten Kunststoffolien bestehen, die über den Rand 13 gleichmäßig vorstehen und in dem vorstehenden Bereich mitteinander verklebt sind. Die Lamellen der Dichtlippe 16 können dadurch ausgebildet werden, daß in dem über den Rand 13 vorstehenden Bereich der Dichtlippe Einschnitte 17 vorgesehen werden, die in einem gleichmäßigen Abstand nebeneinander liegen und bis zum Rand 13 reichen.The edge area 4 is delimited by a semicircular recesses 14 and straight sections 15 with an alternating edge 13, which is designed and rests on the surface contour of conventional roof covering elements, not shown, and rests thereon. The edge 13 is provided over its entire length with a lamellar sealing lip 16 projecting over the edge 13 in the plane of the edge region 4, which is shown only schematically in FIG. This sealing lip 16 can consist of two plastic foils glued onto the top and bottom of the edge area 4, which protrude evenly over the edge 13 and are glued together in the above area. The lamellae of the sealing lip 16 can be formed by providing incisions 17 in the area of the sealing lip projecting beyond the edge 13, which are at a uniform distance from one another and extend to the edge 13.

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 und die Schenkel des Halteabschnitts 18 sind ausreichend starr, so daß nach dem Aufschieben des Haltebereichs 18 auf den Rand 13 die Dichtlippe fest auf dem Rand aufsitzt. Zur Erhöhung der Haltekraft kann die Dichtlippe 16 mit dem Rand 13 noch zusätzlich verklebt werden.Furthermore, it is possible for the sealing lip 16 to be pushed onto the edge 13 of the edge region 4 with a holding section 18 with a U-shaped cross section. The distance between the legs of the holding section 18 in this case is expediently somewhat less than the wall thickness of the edge 13 and the legs of the holding section 18 are sufficiently rigid so that after the holding area 18 has been pushed onto the edge 13, the sealing lip sits firmly on the edge . To increase the holding force, the sealing lip 16 can additionally be glued to the edge 13.

Aufgrund der lamellenartigen Ausbildung schmiegt sich die Dichtlippe 16 eng an die Oberflächenkontur der Dacheindekkungselemente an. Die Dichtlippe 16 bzw. ihre einzelnen Lamellen weisen dabei eine genügend hohe Stabilität auf, um auch bei starken Winden von der Oberfläche der Dacheindekkungselemente nicht abgehoben zu werden.Due to the lamella-like design, the sealing lip 16 clings closely to the surface contour of the roof covering elements. The sealing lip 16 or its individual lamellae have a sufficiently high stability that they are not lifted from the surface of the roof covering elements even in strong winds.

Die Dichtlippe 16 kann aus Kunststoff, aus Gummi oder einem verrottungsfesten Schaunstoff oder Vliesmaterial 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 Aufbringen der Dichtlippe keine nennenswerte Verdickung auftritt und andererseits der Rand 13 der Sauglüfterkappe 1 auch eine gewisse Flexibilität aufweist, die das Anschmiegen der Sauglüfterkappe 1 an die Oberfläche der Dachabdeckungselemente verbessern kann.The sealing lip 16 can be made of plastic, rubber or a rot-proof foam or nonwoven material. Furthermore, it is possible to design the wall thickness of the edge region 4 in the region of the edge 13 to be smaller than in the other regions, so that on the one hand no appreciable thickening occurs due to the application of the sealing lip and on the other hand the edge 13 of the suction fan cap 1 also has a certain flexibility, which Nestling the suction fan cap 1 can improve on the surface of the roof covering elements.

Ferner ist es möglich, den Rand 13 des Randbereichs 4 selbst als Dichtlippe auszubilden, indem die Wandstärke im Bereich des Randes 13 soweit verringert wird, daß sich dieser beim Aufsetzen der Sauglüfterkappe 1 auf die Dacheindeckungselemente an diese anschmiegt. Auch in diesem Fall kann der Rand 13 mit Einschnitten versehen sein, die das Anschmiegen der Dichtlippe an die Dacheindeckungselemente unterstützen.Furthermore, it is possible to design the edge 13 of the edge region 4 itself as a sealing lip, by reducing the wall thickness in the region of the edge 13 to such an extent that it clings to the roof covering elements when the suction fan cap 1 is placed on it. In this case, too, the edge 13 can be provided with incisions which support the sealing lip nestling against the roof covering elements.
