Abstract

The ridge ventilation consists of ventilating flaps (1) made in two symmetrical halves fixed to battens. Each half has a number of protrusions (12) forming openings (5) and recesses (6) staggered w.r.t. the position of the openings. The openings act as ventilating parts, and the recesses serve as supports for the ridge tiles (8), with longitudinal ribs (9) resting against the surface (14) of the recesses.

Description

Die Erfindung betrifft ein Firstentlüftungssystem, bestehend aus in Firstlängsrichtung hintereinander angeordneten, an einer Firstlatte fixierbaren, sich bis zu Firstanschlußziegeln erstreckenden Lüfterfirstkappen sowie diese übergreifenden Firstziegeln, wobei Luftabrißkanten aufweisende Anströmelemente angeordnet und mittels abgewinkelter Bereiche, Ansätze, Einhängenasen oder dergleichen ziegeluntergreifend fixiert oder direkt mit der jeweiligen Lüfterfirstkappe verbunden oder gekuppelt sind.The invention relates to a ridge ventilation system, consisting of fan ridge caps which are arranged one behind the other in the ridge longitudinal direction and can be fixed to a ridge batten and extend as far as ridge connection tiles, and overlapping ridge tiles, air flow edges having inflow elements arranged and fixed by means of angled areas, projections, hanging lugs or the like under the brick or directly with them the respective fan ridge cap are connected or coupled.

Ein derartiges Firstentlüftungssystem ist bereits aus der DE - A - 35 11 798 bekannt. Die Lüfterfirstkappe dieses bekannten Firstentlüftungsystems weist kaminartige Lüftungsöffnungen auf, denen zum Teil hochstehende flexible Lappen zugeordnet sind, die zum Zurückhalten von mitgerissenem Regenwasser bzw. Schnee dienen und sich dazu mit ihrer endseitigen Kante gegen die aufgelegten Firstziegel anlegen. Nachteilig bei diesem bekannten Firstentlüftungssystem ist einerseits, daß die erreichten Unterdruckwerte, die zur Gewährleistung einer ausreichenden Firstentlüftung im Dachbereich erforderlich sind, zum Teil sehr gering sind und andererseits, daß, da nicht allen kaminartigen Öffnungen flexible Lappen zugeordnet sind, Feuchtigkeit über diese kaminartigen Öffnungen in den Dachinnenraum hineingetragen werden kann.Such a ridge ventilation system is already known from DE-A-35 11 798. The fan ridge cap of this known ridge ventilation system has chimney-like ventilation openings, some of which are associated with upstanding flexible tabs, which are used to hold back entrained rainwater or snow and, for this purpose, rest with their end edges against the ridge tiles placed on them. Disadvantages of this known ridge ventilation system are, on the one hand, that the underpressure values achieved, which are required to ensure adequate ridge ventilation in the roof area, are in part very low and, on the other hand, that since flexible flaps are not assigned to all chimney-like openings, moisture in these chimney-like openings in the roof interior can be carried in.

Weiterhin ist aus der DE - A - 23 56 782 ein Firstentlüftungssystem bekannt, das einen Entlüftungskörper aus einer einstückig stranggepreßten Kunststoff-Profilleiste aufweist. Der Entlüftungskörper ist mit einer Sperrwand gegen Witterungseintritt versehen, die in Richtung vom First weg abgewinkelt bzw. abgebogen ist.Furthermore, a ridge ventilation system is known from DE-A-23 56 782, which has a ventilation body made of an integrally extruded plastic profile strip. The venting body is provided with a barrier wall against the ingress of weather, which is angled or bent in the direction away from the ridge.

Der Erfindung liegt die Aufgabe zugrunde, daß Firstentlüftungssystem der eingangs genannten Art derart auszubilden, daß einerseits eine gute Luftzirkulation und eine ausgeprägte Unterdruckerzeugung gewährleistet und andererseits ein ausreichender Schutz gegen Eintrieb von Feuchtigkeit beeispielsweise in Form von Schlagregen und Flugschnee gegeben ist.The invention has for its object that ridge ventilation system of the type mentioned in such a way that on the one hand good air circulation and a pronounced negative pressure generation is guaranteed and on the other hand there is sufficient protection against the ingress of moisture, for example in the form of driving rain and flying snow.

Diese Aufgabe ist bei einer Ausführungsform erfindungsgemäß dadurch gelöst, daß die Anströmelemente im Querschnitt im wesentlichen U-förmig ausgebildet sind, wobei der innenliegende Schenkel den Fixierschenkel und der außenliegende Schenkel die Anströmfläche bildet und der Mittelbereich zwischen den beiden Schenkeln zur Aufnahme der Randbereiche der Firstziegel dient, wobei der den Mittelbereich bildende Verbindungsschenkel mit Wasserabflußöffnungen versehen ist.This object is achieved according to the invention in one embodiment in that the inflow elements are essentially U-shaped in cross-section, the inner leg forming the fixing leg and the outer leg forming the inflow surface and the central region between the two legs serving to accommodate the edge regions of the ridge tiles , wherein the connecting leg forming the central region is provided with water drainage openings.

Alternativ ist bei einer anderen Ausführungsform zur Lösung der genannten Aufgabe vorgesehen, daß die dachinnenseitig angeordneten Anströmelemente jeweils im Anschluß an ihren die Anströmfläche bildenden Abschnitt unter Bildung einer oberen Luftabrißkante etwa rechtwinklig abgewinkelt sind und der abgewinkelte Schenkel wenigstens eine zugeordnete Luftdurchtrittsöffnung zumindest teilweise überdeckt.Alternatively, in another embodiment to solve the above-mentioned problem, the inflow elements arranged on the roof side are angled approximately at right angles to their section forming the inflow surface, forming an upper air separation edge, and the angled leg at least partially covers at least one associated air passage opening.

Durch die mittels der Anströmelemente erzielte Strömungsablösung wird im Firstbereich ein sich insbesondere auch schon bei geringer Umströmung einstellender, ausgeprägter Unterdruck erzeugt, wobei den jeweiligen baulichen Gegebenheiten, insbesondere durch Wahl und Höhe der Anströmelemente und die Ausbildung einer Luftabrißkante oder mehrerer Luftabrißkanten an diesen Anströmelementen, in vorteilhafterweise Rechnung getragen werden kann. Auf diese Weise wird die Hinterlüftung der jeweiligen Dachkonstruktion ganz wesentlich unterstützt.Due to the flow separation achieved by means of the inflow elements, a pronounced negative pressure is established in the ridge area, particularly even with a low flow, with the respective structural conditions, in particular through the choice and height of the inflow elements and the formation of an air separation edge or several air separation edges on these inflow elements can advantageously be taken into account. In this way, the rear ventilation of the respective roof structure is supported significantly.

Besonders zweckmäßig ist es, das im Querschnitt U-förmige Anströmelement mit einer Lüfterfirstkappe zu kombinieren, wobei es möglich ist, eine insgesamt einteilige Ausführungsform vorzusehen oder Lüfterkappen und Anströmelement kuppelbar auszugestalten. Die kuppelbare Ausführungsform hat vor allem den Vorteil, daß eine bestimmte Ausgestaltung einer Lüfterfirstkappe mit unterschiedlichen Anströmelementen kombiniert werden kann, um in baulicher und funktioneller Hinsicht jeweils das angestrebte Optimum zu erreichen. Die Kopplung von Lüfterfirstkappe und Anströmelement kann auf verschiedene Art und Weise erfolgen, und zwar entweder in Form einer festen Verbindung durch Verschweißen, Verkleben, Vernieten und dergleichen oder in Form einer lösbaren Verbindung, wobei sich besonders Schiebeführungen, Steck- oder Einhängeverbindungen, Druckknopfverbindungen oder Klettverschlußverbindungen eignen.It is particularly expedient to combine the inflow element which is U-shaped in cross section with a fan ridge cap, it being possible to provide an overall one-piece embodiment or to design the fan caps and inflow element to be couplable. The detachable embodiment has the particular advantage that a certain configuration of a fan ridge cap can be combined with different inflow elements in order to achieve the desired optimum in terms of construction and function. The coupling of the fan cap and the inflow element can be done in different ways and way take place, either in the form of a fixed connection by welding, gluing, riveting and the like or in the form of a detachable connection, sliding guides, plug-in or hook-in connections, push-button connections or Velcro connections being particularly suitable.

Bei der alternativen Ausführungsform sind die Anströmelemente dachinnenseitig angeordnet und insbesondere lüfterkappenfest ausgebildet. Dabei können die Anströmelemente sich entweder durchgehend über die gesamte Länge der Lüfterfirstkappe erstrecken oder aus Einzelabschnitten bestehen, die jeweils einer Luftdurchtrittsöffnung zugeordnet sind. Die Anströmelemente besitzen im Querschnitt eine abgewinkelte Form und weisen zumindest einen Schenkel auf, der die jeweils zugeordnete Luftdurchtrittsöffnung zumindest teilweise mit Abstand überdeckt. Zweckmäßigerweise ist diese Überdeckung so gewählt, daß die jeweilige Luftdurchtrittsöffnung in Draufsicht zumindest zur Hälfte überdeckt ist. Damit werden Luftdurchtrittsöffnungen vor unerwünschten, in den Dachinnenraum gerichteten Luftströmungen geschützt, aber es wird vor allem erreicht, daß auch unmittelbar benachbart dieser Luftdurchtrittsöffnungen durch Luftabrißkanten Unterdruckeffekte in ausgeprägter Form erzeugt werden und damit eine entscheidende Förderung der Unterdruckbildung im Firstbereich erfolgt, die wiederum maßgeblich dafür ist, daß die erwünschte Dachhinterlüftung in Form einer von innen nach außen gerichteten Strömung erhalten wird.In the alternative embodiment, the inflow elements are arranged on the inside of the roof and in particular are designed such that they are fixed to the fan cap. The inflow elements can either extend continuously over the entire length of the fan ridge cap or consist of individual sections which are each assigned to an air passage opening. The inflow elements have an angled shape in cross section and have at least one leg which at least partially covers the respectively assigned air passage opening at a distance. This covering is expediently chosen such that the respective air passage opening is covered at least half in plan view. This protects air passage openings from unwanted air flows directed into the roof interior, but it is primarily achieved that vacuum effects in a pronounced form are also produced directly adjacent to these air passage openings by air separation edges and thus a decisive promotion of the vacuum formation in the ridge area, which in turn is decisive for this that the desired roof ventilation is obtained in the form of an inside-out flow.

Durch Kombination von dachaußenseitig gelegenen Anströmelementen und dachinnenseitigen bzw. an Lüfterfirstkappen ausgebildeten Anströmelementen kann ein äußerst überraschender Effekt dahingehend erzielt werden, daß sowohl luvseitig als auch leeseitig eine vom Dachinnenraum nach außen gerichtete Strömung erzielt wird, da durch die Spoilerfunktionen die Unterdruckbildung im Firstbereich so gefördert wird, daß bereits bei geringer Umströmung des Firstbereichs und noch viel ausgeprägter bei stärkerer Umströmung des Firstbereichs an allen zum Dachinnenraum führenden Luftdurchtrittsöffnungen sehr ausgeprägte Sogeffekte entstehen.By combining inflow elements located on the outside of the roof and inflow elements on the inside of the roof or formed on fan ridge caps, an extremely surprising effect can be achieved in that a flow directed outwards from the interior of the roof is achieved both on the windward side and on the leeward side, since the formation of negative pressure in the ridge area is promoted by the spoiler functions that even with a small flow around the ridge area and much more pronounced with a strong flow around the ridge area, very pronounced suction effects occur at all air passage openings leading to the roof interior.

Begünstigend wirkt sich auf diesen erwünschten Strömungsverlauf aus, daß die Strömung auf ihrem Weg vom Dachinnenraum nach außen aufgrund der Ausbildung der Lüfterfirstkappen nur einem Minimum an Umlenkungen ausgesetzt ist und somit nur geringfügige Druckverluste entstehen.A beneficial effect on this desired flow is that the flow on its way from the roof interior to the outside is only exposed to a minimum of deflections due to the formation of the fan ridge caps and thus only slight pressure losses occur.

Durch die Möglichkeit der Verbindung von Anströmelementen und Lüfterfirstkappen in Form lösbarer oder fester Verbindungen läßt sich praktisch auch ein Baukastensystem schaffen, durch das den in der Praxis auftretenden Forderungen bestmöglich Rechnung getragen werden kann.The possibility of connecting the inflow elements and fan ridge caps in the form of detachable or fixed connections also makes it possible in practice to create a modular system by which the requirements which arise in practice can be taken into account in the best possible way.

Die Anströmelemente schließen mit den Firstanschlußziegeln bevorzugt einen Winkel im Bereich von 80° bis 110° ein, wobei diese Anströmelemente eben oder zumindest in ihrem freien Endbereich zum First hin abgewinkelt ausgebildet sein können, wobei diese Abwinkelungen zur Ausbildung zusätzlicher Strömungsabrißkanten führen.The inflow elements preferably enclose an angle in the range from 80 ° to 110 ° with the ridge connection tiles, wherein these inflow elements can be flat or at least angled towards the ridge in their free end region, these bends leading to the formation of additional flow separation edges.

Vorzugsweise sind die Anströmelemente innerhalb der Firstziegel über gegenseitig beabstandete Einhängeelemente und dergleichen befestigt oder an First- bzw. Gratabdichtungselementen fixiert bzw. einteilig mit diesen ausgebildet bzw. verbunden.Preferably, the inflow elements are fastened within the ridge tiles via mutually spaced hanging elements and the like, or are fixed to ridge or ridge sealing elements or are formed or connected in one piece to them.

In Fig. 1 ist eine Lüfterfirstkappe 1 dargestellt, die aus Kunststoff vorgebbarer Steifigkeit besteht und einen auch als Nagelleiste zu bezeichnenden Befestigungsbereich 2 für eine Firstlatte, einen Mittelbereich 3 und einen Randbereich 4 umfaßt. Die einzelnen Bereiche gehen über Knickstellen ineinander über.In Fig. 1, a fan ridge cap 1 is shown, which consists of plastic stiffness that can be specified and includes a fastening area 2 for a ridge batten, a central area 3 and an edge area 4, which can also be referred to as a nail bar. The individual areas merge into one another via kinks.

Die dargestellte Lüfterfirstkappe 1 stellt natürlich nur eine Hälfte einer Gesamtkappe dar, wobei eine Gesamtkappe auch einteilig ausgebildet sein könnte.The fan ridge cap 1 shown is of course only one half of an overall cap, and an overall cap could also be formed in one piece.

Im Mittelbereich 3 sind unmittelbar angrenzend an den Befestigungsbereich 2 Luftdurchlaßöffnungen 5 ausgebildet. Diese im Querschnitt vorzugsweise rechteckigen Luftdurchlaßöffnungen 5 sind von firstziegelseitig offenen Ausstülpungen 12 gebildet, deren Höhe etwas geringer ist als die Höhe von sich ebenfalls im Mittelbereich 3 befindenden Ausbuchtungen 6, auf denen die Firstziegel 8 vorzugsweise über insbesondere durchgehende Längsstege 9 abgestützt sind. Die Firstziegel 8 können auch noch mit Querversteifungsstegen 10 ausgestattet sein.In the central region 3, air passage openings 5 are formed immediately adjacent to the fastening region 2. These air passage openings 5, which are preferably rectangular in cross section, are formed by protuberances 12 which are open on the ridge tile side and whose height is somewhat less than the height of bulges 6 which are also located in the central region 3 and on which the ridge tile 8 is preferably supported by in particular continuous longitudinal webs 9. The ridge tile 8 can also be equipped with cross stiffening webs 10.

Die Ausstülpungen 12 und die Ausbuchtungen 6 sind gegenseitig beabstandet und ggf. durch einen Versteifungssteg 11 vergleichsweise geringer Höhe miteinander verbunden. In Längsrichtung der Lüfterfirstkappe 1 betrachtet besitzen die Ausbuchtungen 6 eine etwas geringere Breite als die Luftdurchlaßöffnungen 5, und sie sind zweckmäßigerweise bezüglich dieser Luftdurchlaßöffnungen 5 mittig angeordnet.The protuberances 12 and the bulges 6 are spaced apart from one another and, if appropriate, connected to one another by a stiffening web 11 of comparatively low height. When viewed in the longitudinal direction of the fan ridge cap 1, the bulges 6 have a somewhat smaller width than the air passage openings 5, and they are expediently arranged centrally with respect to these air passage openings 5.

Jeweils zwei nebeneinanderliegende Ausbuchtungen 6 begrenzen zusammen mit dem Mittelbereich 3 der Lüfterfirstkappe 1 und dem auf den Ausbuchtungen 6 abgestützten Längssteg 9 Durchströmungsöffnungen 11' wobei vorzugsweise der freie Querschnitt dieser Durchströmungsöffnungen etwa gleich dem freien Strömungsquerschnitt der durch die Ausstülpungen 12 festgelegten Luftdurchlaßöffnungen 5 ist.Two adjacent bulges 6, together with the central region 3 of the fan ridge cap 1 and the longitudinal web 9 supported on the bulges 6, delimit throughflow openings 11 ', the free cross section of these throughflow openings preferably being approximately equal to the free flow cross section of the air passage openings 5 defined by the protuberances 12.

Die relativ steil verlaufende randbereichseitige Fläche 14 der Ausbuchtungen 6 bildet eine Anströmfläche, die Spoilerfunktion besitzt, wobei an den Begrenzungskanten dieser Anströmfläche 14 Strömungsabrißeffekte auftreten, die zur Unterdruckausbildung beitragen und eine von innen nach außen gerichtete Strömung über die Durchlaßöffnungen 5 begünstigen und fördern. Definierte Strömungsverhältnisse werden dabei auch dadurch erreicht, daß die Luftdurchlaßöffnungen 5 vollständig innerhalb des von den Firstziegelstegen 9 nach außen begrenzten Bereichs gelegen sind.The relatively steep surface 14 of the bulges 6 on the edge region forms an inflow surface which has a spoiler function, flow stall effects occurring at the boundary edges of this inflow surface 14, which contribute to the formation of negative pressure and promote and promote a flow from the inside out through the through openings 5. Defined flow conditions are also achieved in that the air passage openings 5 are located entirely within the area delimited by the ridge tile webs 9.

Die Knickstelle 13 zwischen dem Mittelbereich 3 und dem Randbereich 4 der Lüfterfirstkappe 1 ist so ausgebildet, daß eine ausreichende Kraftübertragung von den Ausbuchtungen 6 zu diesem Randbereich 4 möglich ist, um ein sattes Anliegen dieses Randbereichs 4 oder eines an der Unterseite dieses Randbereichs 4 angebrachten elastischen Formkörpers 7 an den jeweiligen Firstanschlußziegeln sicherzustellen. Der ggf. verwendete elastische Formkörper 7 kann im Querschnitt dreieckförmige oder parallelogrammartige Form besitzen, wobei die Querschnittsform in Abhängigkeit von der Art der Firstanschlußziegel gewählt wird.The kink 13 between the central region 3 and the edge region 4 of the fan ridge cap 1 is designed such that a sufficient transmission of force from the bulges 6 to this edge region 4 is possible in order to provide a snug fit of this edge region 4 or an elastic one attached to the underside of this edge region 4 Ensure molded body 7 on the respective ridge connection tiles. The elastic molded body 7 which may be used can have a triangular or parallelogram-like shape in cross-section, the cross-sectional shape being selected as a function of the type of ridge connecting tile.

Auf dem Randbereich 4 ist an dessen freiem Ende ein leistenförmiger, sich über die Kappenlänge erstreckender Anströmspoiler 16 vorgesehen, der wesentlich zur Unterdruckerhöhung aufgrund von Strömungsabrißeffekten, die an seiner freien Kante auftreten, beiträgt. Das Zusammenwirken dieses Anströmspoilers 16 mit den Ausbuchtungen 6 und den Ausstülpungen 12 wirkt sich in der Praxis überraschend und unerwartet vorteilhaft hinsichtlich der erzielbaren Luftsaugeffekte aus.At the free end of the edge area 4 there is a strip-shaped inflow spoiler 16 which extends over the length of the cap and which contributes significantly to the increase in vacuum due to stall effects which occur at its free edge. The interaction of this inflow spoiler 16 with the bulges 6 and the protuberances 12 has a surprising and unexpectedly advantageous effect in practice with regard to the air suction effects that can be achieved.

Fig. 2 zeigt in schematischer Weise die Anordnung eines Anströmelements 20 im Bereich zwischen den Firstziegeln 21 und den Firstanschlußziegeln 22. Das Anströmelement ist bei dieser Ausführungsvariante im Querschnitt etwa U-förmig ausgebildet, wobei der innenliegende Schenkel 27 als Befestigungsschenkel dient und in nicht dargestellter Weise mit innerhalb der Firstziegel 21 gelegenen vorhandenen Bauelementen bzw. Bestandteilen der Firstkonstruktion verbindbar ist. Der außenliegende Schenkel 28 stellt die eigentliche Anströmfläche dar. Die beiden Schenkel 27, 28 sind über einen den Boden bildenden Mittelbereich 29 miteinander verbunden, wobei zwischen dem Mittelbereich 29 und den Firstziegeln 21 Luftdurchlaßöffnungen 25 vorhanden sind.Fig. 2 shows schematically the arrangement of a flow element 20 in the area between the ridge tiles 21 and the ridge connection tiles 22. The flow element in this embodiment is approximately U-shaped in cross section, the inner leg 27 serving as a fastening leg and in a manner not shown can be connected to existing components or components of the ridge construction located within the ridge tile 21. The outer limb 28 represents the actual inflow surface. The two limbs 27, 28 are connected to one another via a central region 29 forming the floor, air passage openings 25 being present between the central region 29 and the ridge tiles 21.

An den Mittelbereich 29 können Stützelemente 32 für die Firstziegel 21 angeformt sein. Außerdem sind Maßnahmen in Form von Löchern, Schlitzen und dergleichen getroffen, um einen Wasserablauf aus der rinnenartigen Struktur zu ermöglichen.Support elements 32 for the ridge tiles 21 can be molded onto the central region 29. In addition, measures in the form of holes, slots and the like have been taken in order to allow water to drain from the channel-like structure.

Der außenliegende, die Anströmfläche bildende Schenkel 28 kann an seinem freien Ende mit einer Abwinkelung 26 versehen sein, die bezüglich der Anströmfläche unterschiedlich geneigt ist, wie dies in Fig. 2 strichliert angedeutet wurde. Auf diese Weise können besonders günstige Strömungsabrißgegebenheiten geschaffen werden.The outer leg 28 forming the inflow surface can be provided at its free end with an angled portion 26, which is inclined differently with respect to the inflow surface, as was indicated by the broken line in FIG. 2. In this way, particularly favorable stall conditions can be created.

Zum Zwecke der Erhöhung der Stabilität kann das Anströmelement 20 mit Ansatzelementen 24 in Stegform ausgestattet sein, über die eine Abstützung auf den Firstanschlußziegeln erfolgt.For the purpose of increasing stability, the inflow element 20 can be equipped with attachment elements 24 in the form of a web, via which elements are supported on the ridge connection tiles.

Die Schnittansicht nach Fig. 3 zeigt verschiedene Varianten einer möglichen Kombination von Anströmelementen mit Lüfterfirstkappen.The sectional view according to FIG. 3 shows different variants of a possible combination of inflow elements with fan ridge caps.

In der linken Hälfte der gezeigten Lüfterfirstkappe 33 sind zwei Varianten von Anströmelementen 20 gezeigt, die einer Luftdurchlaßöffnung 25 zugeordnet sind, welche an der Oberseite einer Ausstülpung angebracht ist. Die Anströmelement 20 bestehen aus abgewinkelten, sich in Längsrichtung der Lüfterfirstkappe 20 erstreckenden Teilen, die unmittelbar angrenzend an die Luftdurchlaßöffnung 25 befestigt sind und sich über die Luftdurchlaßöffnung 25 erstrecken, wobei die Distanz zwischen der Luftdurchlaßöffnung 25 und dem übergreifenden Schenkel des Anströmelements 20 frei wählbar ist und der optimale Abstand insbesondere durch entsprechende Strömungsversuche ermittelt werden kann.In the left half of the fan ridge cap 33 shown, two variants of inflow elements 20 are shown, which are assigned to an air passage opening 25, which is attached to the top of a protuberance. The inflow element 20 consist of angled parts which extend in the longitudinal direction of the fan ridge cap 20 and are fastened directly adjacent to the air passage opening 25 and extend over the air passage opening 25, the distance between the air passage opening 25 and the overlapping leg of the inflow element 20 being freely selectable and the optimal distance can be determined in particular by appropriate flow tests.

Diese Anströmelemente 20 weisen Abrißkanten 23 auf, die im Betrieb Ursache für eine Unterdruckerzeugung sind, welche wiederum dazu führt, daß sich eine vom Dachinnenraum nach außen über die Luftdurchlaßöffnungen 25 gerichtete Strömung erzielen läßt.These inflow elements 20 have tear-off edges 23, which in operation are the cause of a negative pressure generation, which in turn leads to the fact that a flow directed outwards from the roof interior via the air passage openings 25 can be achieved.

Während das im linken Teil der Lüfterfirstkappe als fest angebrachtes Anströmelement 20 gezeigte Element mit zwei Abrißkanten 23 versehen ist, weist das alternativ vorgesehene Anströmelement anschließend an den Befestigungsbereich nur eine etwa rechtwinkelige Knickstelle auf.While the element shown in the left part of the fan ridge cap as a fixed inflow element 20 is provided with two tear-off edges 23, the alternatively provided inflow element then only has an approximately right-angled kink at the fastening area.

Im rechten Teil der Fig. 3 ist eine Variante einer Lüfterfirstkappe gezeigt, die im Randbereich mit Höckern 31 zur Abstützung von Firstziegeln ausgestattet ist und die an der Unterseite des Randbereichs mit einem Abdichtelement 35 ausgestattet sein kann.In the right part of FIG. 3, a variant of a fan ridge cap is shown, which is equipped in the edge area with bumps 31 for supporting ridge tiles and which can be equipped with a sealing element 35 on the underside of the edge area.

Zwischen den Luftdurchlaßöffnungen 25 und den Höckern 31 ist ein Anströmelement 20 mit einer Luftabrißkante 23 vorgesehen. Dieses Anströmelement 20 hat im Querschnitt L-förmige Gestalt, wobei der eine Schenkel die Anströmfläche bildet und der andere Schenkel zu Befestigungszwecken dient.Between the air passage openings 25 and the bumps 31 an inflow element 20 with an air separation edge 23 is provided. This inflow element 20 has an L-shaped cross-section, one leg forming the inflow surface and the other leg serving for fastening purposes.

Anstelle dieses im Querschnitt L-förmigen Anströmelements 20 können aber auch die schematisch angedeuteten Ausführungsvarianten verwendet werden, welche die jeweils zugeordneten Luftdurchlaßöffnungen 25 zur Hälfte oder mehr überdecken und gegebenenfalls mit zusätzlichen Luftabrißkanten 23 versehen sind.Instead of this inflow element 20, which is L-shaped in cross section, the schematically indicated design variants can also be used, which cover the respectively assigned air passage openings 25 by half or more and are optionally provided with additional air separation edges 23.

Alternativ oder zusätzlich zu den innerhalb der Firstziegel gelegenen und unmittelbar den Lüftungsöffnungen 25 zugeordneten Anströmelementen 20 können auch außenseitig gelegene Anströmelemente 20 verwendet werden, die mit der Lüfterfirstkappe 33 kuppelbar oder fest verbunden sind.As an alternative or in addition to the inflow elements 20 located within the ridge tiles and directly assigned to the ventilation openings 25, externally located inflow elements 20 can also be used, which can be coupled or fixedly connected to the fan ridge cap 33.

Diese Anströmelemente 20 besitzen im Querschnitt eine etwa U-förmige Struktur, wobei der innenliegende Befestigungsschenkel 27 mit der Lüfterfirstkappe 33 verbunden ist und der außenliegende Schenkel 28 die Anströmfläche mit Abrißkante 23 bildet. Im Mittelbereich 29 sind Wasserabflußöffnungen 30 ausgebildet.These inflow elements 20 have an approximately U-shaped structure in cross section, the inner fastening leg 27 being connected to the fan ridge cap 33 and the outer leg 28 forming the inflow surface with tear-off edge 23. Water drainage openings 30 are formed in the central region 29.

Die perspektivische Ansicht nach Fig. 4 zeigt die Kombination einer Lüfterfirstkappe 33 mit Firstziegel-Abstützelementen 31 mit einem im Querschnitt etwa U-förmigen Anströmelement 20, wobei die zugeordneten Firstziegel in das U-Profil eingreifen und die die Luftabrißkante 23 aufweisende außenliegende Anströmfläche über die Dachaußenseite vorsteht. Dieses Anströmelement 20 kann zwar unmittelbar an die Lüfterfirstkappe 33 angeformt sein, aber zweckmäßigerweise handelt es sich dabei um ein separates Teil, das je nach Bedarf mit der Lüfterfirstkappe 33 verklebt, verschweißt, vernietet oder in sonstiger Weise dauerhaft verbunden werden kann. Es ist auch möglich, zu Kupplungszwecken die Abstützelemente 31 zu nützen, wobei in diesem Falle der innenliegende Schenkel des Anströmelements 20 länger ausgeführt und mit entsprechenden Öffnungen versehen wird, durch die die Stützelemente 31 treten können.The perspective view according to FIG. 4 shows the combination of a fan ridge cap 33 with ridge tile support elements 31 with an inflow element 20 which is approximately U-shaped in cross section, the associated ridge tiles engaging in the U profile and the outside inflow surface having the air separation edge 23 via the outside of the roof protrudes. This inflow element 20 can be formed directly on the fan ridge cap 33, but expediently it is a separate part that can be glued, welded, riveted or otherwise permanently connected to the fan ridge cap 33 as required. It is also possible to use the support elements 31 for coupling purposes, in which case the inner leg of the inflow element 20 is made longer and provided with corresponding openings through which the support elements 31 can pass.

Fig. 5 zeigt in einer perspektivischen Teildarstellung eine Ausführungsform mit innerhalb des Firstziegels liegenden Anströmelementen 20, die ausgehend von einem gemeinsamen, sich über die Länge der Lüfterfirstkappe 33 erstreckenden Befestigungsschenkel 36 sich jeweils zumindest bereichsweise über die zugeordneten Luftdurchlaßöffnungen 25 in der Lüfterfirstkappe 33 erstrecken. Damit schützen sie einerseits die Luftdurchtrittsöffnungen 25 vor den Aufbau von Unterdruck störenden Strömungen und bewirken andererseits aufgrund der Abrißkanten 23 die Erzeugung von Unterdruckbereichen, welche die Strömung von innen nach außen bewirken bzw. zumindest begünstigen.5 shows a perspective partial view of an embodiment with inflow elements 20 located within the ridge tile, which, starting from a common fastening leg 36 which extends over the length of the fan ridge cap 33, each extend at least in regions over the associated air passage openings 25 in the fan ridge cap 33. Thus, on the one hand, they protect the air passage openings 25 from the build-up of currents which disrupt negative pressure and, on the other hand, because of the tear-off edges 23, they produce negative pressure regions which Effect or at least favor flow from the inside out.

Allen Ausführungsvarianten ist auch gemeinsam, daß die Anströmelemente gleichzeitig Schutzelemente gegen Eintrieb von Schlagregen und Flugschnee bilden und entscheidend zur Unterdruckausbildung im Firstbereich beitragen.It is also common to all design variants that the inflow elements at the same time form protective elements against driving rain and flying snow and make a decisive contribution to the formation of negative pressure in the ridge area.
