Description

Die Erfindung bezieht sich auf einen als Dacheindeckungsplatte gestalteten Dachentlüfter mit einem mittelständigen, kuppelförmigen Dom, dessen Höhe größer ist als seine Breite und kleiner als seine Länge, und der oberseitig eine Öffnung besitzt zum Durchtritt eines Lüftungsanschlußrohres, dessen Durchmesser etwa der Breite des Domes entspricht und kleiner ist als seine Länge und welches eine den oberen Rand des Domes überfangende Kappe besitzt, die im Scheitelbereich ein Luftdurchtrittsloch aufweist und sich abdeckend über den Abstand erstreckt, den das Lüftungsanschlußrohr in Richtung der Länge des Domes zum Domrand hin beläßt.The invention relates to a roof vent designed as a roof covering with a central, dome-shaped dome, the height of which is greater than its width and smaller than its length, and which has an opening on the top side for the passage of a ventilation connection pipe, the diameter of which corresponds approximately to the width of the dome and is smaller than its length and which has a cap overlapping the upper edge of the dome, which has an air passage hole in the apex region and extends covering the distance that the ventilation connection tube leaves in the direction of the length of the dome towards the dome edge.

Ein Dachentlüfter dieser Art ist durch die DE-A-2 128 35 bekannt. Der die Dacheindeckungsplatte überragende Dom besteht dort aus pagoden- bzw. stufendachartigen Aufsätzen aus z.B. Blech. Der oberste Aufsatz ist deckenseitig unter Bildung von Lüftungsschlitzen durchbrochen.A roof vent of this type is known from DE-A-2 128 35. The dome protruding over the roof covering plate consists of pagoda or step roof-like attachments made of e.g. Sheet. The top attachment is perforated on the ceiling to form ventilation slots.

Durch die DE-A-2 535 255 ist es bekannt, den Dom mittels einer konturenangepaßten Kappe zu überfangen, welche mit dem Lüftungssystem in Verbindung steht, so daß ein sich nach oben hin schornsteinartig fortsetzendes Rohr-Oberteil unabhängig von der jeweiligen Dachflächenneigung in die Vertikale gebracht und in dieser Stellung gesichert werden kann.From DE-A-2 535 255 it is known to overlap the dome by means of a contoured cap, which is connected to the ventilation system, so that an upward chimney-like pipe top part is vertical regardless of the respective roof surface inclination brought and secured in this position.

Aufgabe der Erfindung ist es, Dachentlüfter der angegebenen Gattung baulich und lüftungstechnisch zu verbessern. Gelöst ist diese Aufgabe durch die im Anspruch 1 angegebene Erfindung. Die weiteren Ansprüche geben bevorzugte Ausgestaltungen an.The object of the invention is to improve roof ventilators of the type specified in terms of construction and ventilation technology. This object is achieved by the invention specified in claim 1. The further claims indicate preferred configurations.

Zufolge solcher Ausgestaltung ist ein gattungsgemäßer, als Dacheindeckungsplatte gestalteter Dachentlüfter geschaffen, der sich durch einfachen Aufbau und günstige Voraussetzungen im Hinblick auf die wirksame Entlüftung auszeichnet. Auch in stabilisatorischer Hinsicht liegen Vorteile vor. Konkret ist so vorgegangen, daß das Loch der Kappe als sich bis über den Abstandsbereich erstrekkende Lüftungsgitter-Öffnung gestaltet ist und der größere, längsliegende Durchmesser der Lüftungsgitter-Öffnung über eine trichterförmige Gleitfläche in den kreisrunden Querschnitt des Lüftungsanschlußrohres einläuft. Es bedarf keines besonderen Zusatzbauteiles. Die integrale Gitterung setzt sich in Form formtechnisch gleich mitangeformter Stabilisierungsstreben über den den Lüftungsquerschnitt bildenden Bereich fort. Die zweckmäßig in der längeren Erstreckungsrichtung des Domes orientierten Gitterelemente führen zu einer äußerst strömungsgünstigen, weitestgehend verwirbelungsfreien Mündung des Öffnungsbereichs. Solche, das Lüftungsgitter bildende Materialstege schaffen auch unmittelbar nach dem Entformen des Bauteiles einen stabilen Verbund. Auch optisch-visuell liegt keine Störung vor, da der Domsilhouette gefolgt werden kann. Natürlich kann - wie beim Ausführungsbeispiel bevorzugt - die entsprechende Überstandslage auf beiden diametral einander gegenüberliegenden Seiten realisiert sein. In jedem Fall ergibt sich durch die Umformung des in der Regel kreisrunden Querschnitts in einen elliptischen, langlochartigen Öffnungsmund eine strömungsgünstigere Öffnungsschale zur Außenluft hin. Außerdem erweist es sich als vorteilhaft, daß das Lüftungsgitter, das Lüftungsanschlußrohr und die übergreifende Kappe einstückig gestaltet sind. Hier liegen also die gleichen stabilisatorischen sowie entlüftungstechnischen Vorteile vor, wobei jedoch die bei vorbekannten Lösungen mögliche Winkeleinstellung der Dacheindeckungsplatte zur vertikalen Ausrichtung des Lüftungsanschlußrohres in gleich günstiger Weise gegeben ist. Eine solche Kappe steht nicht wesentlich über den selbst ebenfalls recht gedrungen gestalteten Dom über. Der entsprechende Überstand liegt praktisch nur bei einer Materialstärke bzw. Dicke der Kappe. Der entsprechende Verzicht auf die exponierte, in der Regel recht hoch ansteigende schornsteinartige Gestalt des Entlüftungsoberteils stellt sich auch als günstiger heraus in Bezug auf sturmbezogene Belastungen bzw. gegenüber aus der Schneelast herrührenden mechanischen Beanspruchungen. Soll verhindert werden, daß Regen etc. in das Lüftungsrohr gelangt, so läßt sich die diesbezügliche Öffnung sprich Lüftungsgitter durch eine dem Dom konturengleich gestaltete Abdeckkappe oberhalb des Lüftungsgitters überfangen. Die Anordnung oberhalb des Lüftungsgitters ist dabei so, daß der erforderliche Luftaustausch in genügendem Maße beibehalten wird. Es genügt im allgemeinen eine fingerbreite Abstandslage zur Oberseite der Kappe. In Bezug auf die Befestigung der Abdeckkappe an der Kappe wird vorgeschlagen, daß das Lüftungsgitter zwei in Richtung der Längsrichtung des Domes liegende Speichen besitzt, zwischen denen eine Büchse als Steckaufnahme für einen Haltezapfen der das Lüftungsgitter überfangenden, konturengleich bzw. -angepaßt zum Dom gestalteten Abdeckkappe. Die Büchse erfüllt dabei eine Zusatzfunktion, indem sie die recht langen Speichen wie eine Materialbrücke miteinander verbindet, dies zweckmäßig im Mittelbereich der Speichen. Da die Büchse andererseits an begrenzt beweglichen, jedenfalls nicht starren, frei gespannten Speichen sitzt, ergibt sich eine vorteilhafte anpassende Ausweichbewegung bei nicht exakt axial ausgerichtetem Haltezapfen. Zur Sicherung der Steckzuordnung kann ein solcher Haltezapfen mit Rastvorsprüngen versehen sein, etwa in der Weise, daß sein steckaktives Ende einen Kreuzschlitz besitzt, dessen lichte Breite den für das Zurückweichen der Rastnasen notwendigen Ausweichraum bringt. Weiter erweist es sich als günstig, daß die Abdeckkappe helmartig gestaltet ist und traufenseitig einen abgesetzten Kappenschirm ausbildet. Der gegenüber dem helmartigen Kappenkörper zurückgeschnittene Schirm bildet eine bevorzugte Luftaustauschfläche, während aber auch ringsrum die Überfangszone der Kappe den entsprechenden allseitigen Luftaustausch mitfördert, gegenüber dem traufenseitigen herabfließenden Regenschwall jedoch eine größere Überlappungszone durch den viel tieferen Helmrand schafft. Endlich wird noch vorgeschlagen, daß die traufenseitige Querzone der Kappe und/oder der Abdeckkappe mit zur Seite ausladenden Stufen gestaltet ist. Solche im bevorzugten Lüftungsabschnitt liegenden Stufen vermeiden ein sturmbedingtes Hochtreiben des ablaufenden Regenwassers gegen die innere Öffnung; die Stufen vermitteln vielmehr ein nach auswärts gerichtetes Ablaufen in Richtung des Fußes des Domes.As a result of such an embodiment, a generic roof vent is designed as a roof covering plate, which is characterized by a simple structure and favorable conditions with regard to effective ventilation. There are also advantages in terms of stabilization. Specifically, the procedure is such that the hole in the cap is designed as a ventilation grille opening extending over the spacing area and the larger, longitudinal diameter of the ventilation grille opening runs into the circular cross section of the ventilation connection pipe via a funnel-shaped sliding surface. No special additional component is required. The integral lattice continues in the form of the shape of the stabilizing struts over the area forming the ventilation cross-section. The lattice elements, which are expediently oriented in the longer direction of extension of the dome, lead to an opening of the opening area which is extremely streamlined and largely free of turbulence. Such material webs forming the ventilation grille create a stable bond immediately after the component has been removed from the mold. There is also no visual or visual disturbance, since the cathedral silhouette can be followed. Of course - as is preferred in the exemplary embodiment - the corresponding overhang position can be realized on both diametrically opposite sides. In any case, the reshaping of the generally circular cross section into an elliptical, slot-like opening mouth results in a more streamlined opening shell to the outside air. It also proves advantageous that the ventilation grille, the ventilation connection pipe and the overlapping Cap are designed in one piece. Here there are the same stabilizing and ventilation advantages, but the possible angle adjustment of the roof covering plate for vertical alignment of the ventilation connection pipe is given in an equally favorable manner. Such a cap does not project significantly beyond the cathedral itself, which is also quite compact. The corresponding overhang is practically only with a material thickness or thickness of the cap. The corresponding waiver of the exposed, usually quite high chimney-like shape of the upper venting part also turns out to be more favorable in relation to storm-related loads or mechanical loads resulting from the snow load. If it is to be prevented that rain etc. gets into the ventilation pipe, the relevant opening, i.e. ventilation grille, can be overlaid by a cover cap of the same shape as the dome above the ventilation grille. The arrangement above the ventilation grille is such that the required air exchange is maintained to a sufficient extent. A finger-wide spacing from the top of the cap is generally sufficient. With regard to the attachment of the cover cap to the cap, it is proposed that the ventilation grille has two spokes lying in the direction of the longitudinal direction of the dome, between which a bushing as a plug-in receptacle for a holding pin of the cover cap overlapping the ventilation grille, designed to match the shape or shape of the dome . The bushing fulfills an additional function by connecting the rather long spokes like a material bridge, expediently in the central area of the spokes. Since, on the other hand, the bush is seated on spokes that are limitedly movable, in any case not rigid, freely tensioned, there is an advantageous adaptive evasive movement if the holding pin is not exactly axially aligned. To secure the plug-in assignment, such a holding pin can be provided with locking projections, for example in such a way that its plug-in active end has a cross-slot, the clear width of which provides the evasive space necessary for the locking lugs to retreat. Furthermore, it proves to be favorable that the cover cap is designed like a helmet and forms a stepped cap screen on the eaves side. The cut back vis-à-vis the helmet-like cap body forms a preferred air exchange surface, while the cap's overlap zone also promotes the corresponding all-round air exchange, but creates a larger overlap zone compared to the rainwater flowing down the eaves side due to the much deeper rim of the helmet. Finally, it is also proposed that the eaves-side transverse zone of the cap and / or the cover cap be designed with steps that protrude to the side. Such steps located in the preferred ventilation section avoid storm-induced blowing up of the running rainwater against the inner opening; the steps convey an outward flow towards the foot of the cathedral.

Die als Dachentlüfter D gestaltete Dacheindeckungsplatte 1 ist zwecks optisch guter Einpassung in das Flächenbild eines Daches in ihrem Grundaufbau wie die übrigen Dacheindeckungsplatten (Dachpfannen) gestaltet.The roof covering plate 1, which is designed as a roof ventilator D, is designed in its basic structure like the other roof covering plates (roof tiles) in order to fit optically well into the surface area of a roof.

Von der in Art der Dachpfanne profilierten Dacheindeckungsplatte 1 geht ein nach oben gerichteter Dom 2 aus. Er ist der Dacheindeckungsplatte 1 gleich angeformt und erstreckt sich im Mittelbereich derselben. Bezogen auf das Profil der Dacheindeckungsplatte erstreckt sich der Dom 2 in der Ebene einer mittelständigen, nach oben quer konvex gewölbten, in der Neigungsrichtung verlaufenden Rippe 3. Da der Grundriß des Domes 2 auch noch die benachbarten flachen Partien 4 der Dacheindeckungsplatte teilweise einbezieht, ergibt sich ein ovaler, in Höhenrichtung jedoch unterschiedlicher Anbindungs- bzw. Übergangsbereich, gangsbereich, was sich auf die Stabilität des Domes 2 förderlich auswirkt.An upward-facing dome 2 extends from the roof covering plate 1, which is profiled in the manner of the roof tile. It is the same as the roof covering plate 1 and extends in the central region thereof. In relation to the profile of the roofing slab, the dome 2 extends in the plane of a central rib 3, which is convexly curved upwards and extends in the direction of inclination an oval, but in the height direction different connection or transition area, aisle area, which has a beneficial effect on the stability of the dome 2.

Der Dom 2 ist in Neigungsrichtung der Dacheindeckungsplatte 1 länger ausgebildet als seine Breite beträgt. Dabei ist die Höhe des Domes 2 größer als die Breite und kleiner als die Länge des Domes. Es handelt sich um eine zweifach gekrümmte Anformung, wobei die im wesentlichen parallel verlaufenden Querwände des Domes im Basisbereich desselben ebenflächige Seitenwände 5 bilden, wobei aber diese Querwände im oberen Bereich kuppelförmig zulaufen. In Längsrichtung liegt also ein größerer Wölbungsverlauf vor als in Querrichtung.The dome 2 is longer than its width in the direction of inclination of the roofing plate 1. The height of the dome 2 is greater than the width and smaller than the length of the dome. It is a double-curved formation, the essentially parallel transverse walls of the dome forming flat side walls 5 in the base region thereof, but these transverse walls tapering in a dome shape in the upper region. There is therefore a greater curvature in the longitudinal direction than in the transverse direction.

Der die Krümmung der Längswölbung bestimmende Radius R fußt etwa im Schnittpunkt der Diagonalen der im Grunde rechteckigen Dacheindeckungsplatte. Dieser Radiuspunkt ist mit x bezeichnet. Der Radiuspunkt der Querwölbung ist mit y bezeichnet und erstreckt sich auf einer kreisförmigen Bogenbahn um den Radiuspunkt x. Der vom Radiuspunkt y ausgehende Radius R' ist von halber Länge des vom Radiuspunkt x ausgehenden Radius' R.The radius R determining the curvature of the longitudinal curvature is based approximately at the intersection of the diagonals of the basically rectangular roof covering plate. This radius point is labeled x. The radius point of the transverse curvature is designated y and extends on a circular arc around the radius point x. The radius R 'starting from the radius point y is half the length of the radius' R starting from the radius point x.

Wie Figur 6 deutlich entnehmbar, läuft im Scheitelbereich des Domes 2 eine Öffnung Ö aus. Dieser die Öffnung Ö umschreibende Scheitelbereich ist als Endstück eines Lüftungsanschlußrohres 6 ausgebildet. Dort gehen Domwandung und Rohrwandung einstückig ineinander über, vorzugsweise unter Beibehaltung einer gleichen Wandungsdicke, die hier recht dünn ausfallen kann zufolge der polydirektionalen Ausrichtung der Wandungspartien, was zu einem hohen Versteifungseffekt führt.As can be clearly seen in FIG. 6, an opening Ö runs out in the apex region of the dome 2. This apex region circumscribing the opening Ö is designed as an end piece of a ventilation connection pipe 6. There, the dome wall and the tube wall merge into one another, preferably while maintaining the same wall thickness, which can be quite thin here due to the polydirectional orientation of the wall parts, which leads to a high stiffening effect.

Die Öffnung Ö bildet den Rahmen Ra eines Lüftungsgitters 7.The opening Ö forms the frame Ra of a ventilation grille 7.

Das Lüftungsgitter 7 besitzt zwei in Richtung der Längserstreckung des Domes 2 liegende Speichen 8. Im Vertikalschnitt gemäß Fig. 6 u. 10 gesehen, nimmt die Oberkante der vertikal ausgerichteten Speichen 8 einen der Wölbung des Domes 2 entsprechenden Verlauf. Die Speichen 8 reichen deutlich in die Öffnung Ö vertikal hinein und sind auch unterseitig konvex gewölbt. Aus Fig. 8 wird deutlich, daß die beiden Speichen 8 parallel verlaufen. Ihr Zwischenraum 9 ist von einer Beabstandung, die auch außenseitig der Speichen im wesentlichen eingehalten ist zum dortigen schwach gekrümmten Abschnitt des Rahmens Ra.The ventilation grille 7 has two spokes 8 lying in the direction of the longitudinal extent of the dome 2. In the vertical section according to FIG. 10 seen, the upper edge of the vertically aligned spokes 8 takes a course corresponding to the curvature of the dome 2. The spokes 8 clearly extend vertically into the opening Ö and are also convexly curved on the underside. From Fig. 8 it is clear that the two spokes 8 run parallel. Your intermediate space 9 is spaced apart, which is also essentially maintained on the outside of the spokes from the slightly curved section of the frame Ra there.

Die wie ein Mund gestaltete, unterhalb in das Lüftungsanschlußrohr 6 übergehende Öffnung Ö weist einen ovalen, bzw. wie dargestellt, eher elliptischen Umriß auf, wobei die längere Ellipsenachse in der Neigungsrichtung der Dacheindeckungsplatte 1 liegt.The opening O, shaped like a mouth and passing below into the ventilation connection pipe 6, has an oval, or rather, as shown, rather elliptical outline, the longer axis of the ellipse lying in the direction of inclination of the roof covering plate 1.

Wie Fig. 8 weiter entnehmbar, ist der querliegende Durchmesser der elliptischen Lüftungsgitter-Öffnung Ö etwa gleich demjenigen des Lüftungsanschlußrohres 6 bzw. leicht darunter. Der Durchmesser der längeren Ellipsenachse überschreitet dagegen den Rohrdurchmesser. In deutlicher Erweiterung geht daher der die Öffnung formende Bereich der Ellipse in eine Art Trichter T über. Der Trichter T öffnet nach außen hin. Obwohl der Trichter T symmetrisch zugeordnet sein könnte, ist beim Ausführungsbeispiel eine Ausgestaltung dahingehend gewählt, daß die traufenseitige Kehre der elliptischen Öffnung Ö etwas kleiner abschneidet d.h. in kürzerem Anschluß zum dortigen traufenseitigen Querschnittsbereich 6' des Lüftungsanschlußrohres 6 steht. Der Trichter T schließt also spitzwinklig an mit leichter firstseitiger Neigung. Die trichterförmige Mundform liegt demzufolge auf der traufenseitigen Hälfte des zylindrischen Lüftungsrohrquerschnitts höher. Die vom Trichter T gebildete, firstseitige Abgleitfläche trägt das Bezugzeichen 10, die andere, kürzere 10'. In beiden wurzeln die Enden der Speichen 8.As can also be seen in FIG. 8, the transverse diameter of the elliptical ventilation grille opening Ö is approximately equal to that of the ventilation connection pipe 6 or slightly below it. The diameter of the longer ellipse axis, however, exceeds the pipe diameter. The area of the ellipse that forms the opening then merges into a kind of funnel T. The funnel T opens outwards. Although the funnel T could be assigned symmetrically, an embodiment is selected in the exemplary embodiment such that the eaves-side bend of the elliptical opening Ö cuts off a little smaller, that is to say it has a shorter connection to the cross-sectional area 6 ′ of the ventilation connection pipe 6 there. The funnel T thus adjoins at an acute angle with a slight slope on the ridge side. The funnel-shaped mouth shape is therefore on the eaves-side half of the cylindrical ventilation pipe cross-section higher. The ridge-side sliding surface formed by the funnel T bears the reference number 10, the other, shorter 10 '. The ends of the spokes 8 are rooted in both.

Erfolgt der Anschluß der dargestellten Dacheindeckungsplatte 1 nicht an einer mit dem Kanalsystem verbundenen Abflußleitung, und dient beispielsweise Dachentlüftungszwecken, so wird dem Dom 2 eine helmförmige Abdeckkappe 11 zugeordnet. Diese überfängt den Scheitel des Domes 2 unter allseitiger vertikaler Überlappung des Rahmens Ra, so daß beispielsweise Schlagregen nicht in die Öffnung Ö gelangen kann.If the roof covering plate 1 shown is not connected to a drain line connected to the duct system and is used, for example, for roof ventilation purposes, the dome 2 is assigned a helmet-shaped cover cap 11. This covers the top of the dome 2 with vertical overlap of the frame Ra so that, for example, driving rain cannot get into the opening Ö.

Die Abdeckkappe 11 besitzt eine der Wölbungsform des Domes 2 weitestgehend angepaßte bzw. konturengleiche Gestalt, so daß nur ein Belüftungspalt 12 zwischen der Oberseite des Domes und der Innenseite der Abdeckkappe 11 verbleibt. Ein solcher Belüftungsspalt 12 kann allseitig vorgesehen sein, befindet sich zumindest aber im Bereich eines der Abdeckkappe angeformten Schirmes 13. Die darunter liegende Zone kann als Fenster 14 bezeichnet werden, denn von den Schirmenden ausgehend erstrecken sich Seitenwände 15 der Abdeckkappe unter größerer Abdeckung der der Öffnung Ö naheliegenden Bereiche der Seitenwände 5 des Domes. Hier kann sogar eine seitlich berührende Stützanlage zwischen den Seitenwänden 15 und den korrespondierenden Seitenwänden 5 genutzt werden und beispielsweise der dem Schirm 13 abgewandte Kappenrand sich wieder von der Oberseite des Domes abheben.The cover cap 11 has a shape that is largely adapted to the curvature of the dome 2 or has the same shape, so that only one ventilation gap 12 remains between the top of the dome and the inside of the cover cap 11. Such a ventilation gap 12 can be provided on all sides, but is at least located in the area of a screen 13 formed on the cover cap. The zone underneath can be referred to as window 14, because starting from the screen ends, side walls 15 of the cover cap extend to cover the opening to a greater extent Ö nearby areas of the side walls 5 of the cathedral. Here even a laterally contacting support system between the side walls 15 and the corresponding side walls 5 can be used and, for example, the edge of the cap facing away from the screen 13 can be lifted off the top of the dome again.

Was nun die Befestigung der Abdeckkappe 11 angeht, so ist diesbezüglich so vorgegangen, daß zwischen den Speichen 8 des Lüftungsgitters 7 eine Büchse 16 sitzt. Letztere wird den besagten Speichen zweckmäßig gleich mit angeformt und weist zweckmäßig auch deren Höhe auf. Die geometrische Achse der Büchse 16 verläuft etwa raumparallel zu der des Lüftungsanschlußrohres 6. Die Büchse 16 bildet eine Steckaufnahme für einen Haltezapfen 17. Letzterer geht von der Unterseite der Abdeckkappe 11 aus und ist ebenfalls dort gleich materialeinheitlich angeformt. Er ermöglicht die zentrierte Zuordnung und geht deckenseitig in einen Distanzbund 18 über, welcher auf die obere Stirnseite der Büchse 16 aufsetzt. Zur unverlierbaren Zuordnung weist der steckaktive Abschnitt des Haltezapfens 17 eine Kreuzschlitzung auf. Hierdurch entstehen vier Rasthaken mit nach auswärts gerichteter Rastnase 19, die den unteren Stirnrand der Büchse 16 sperrend überfangen.As far as the fastening of the cover cap 11 is concerned, the procedure in this regard is that a bush 16 is seated between the spokes 8 of the ventilation grille 7. The latter is appropriately molded to the said spokes and expediently also has their height. The Geometric axis of the sleeve 16 runs approximately parallel to that of the ventilation connection pipe 6. The sleeve 16 forms a plug-in receptacle for a holding pin 17. The latter extends from the underside of the cover cap 11 and is also molded there from the same material. It enables the centered assignment and merges into a spacer collar 18 on the ceiling, which is placed on the upper end face of the sleeve 16. For the captive assignment, the plug-in section of the holding pin 17 has a cross slot. This results in four latching hooks with an outwardly directed latching lug 19 which overlap the lower end edge of the sleeve 16.

Wie der zeichnerischen Darstellung entnehmbar, ist der traufenseitig angeformte Schirm 13 der helmartig gestalteten Abdeckkappe 11 stufenförmig abgesetzt. Die einzelnen, im wesentlichen gleich beabstandeten Stufen tragen das Bezugszeichen 20. Sie erstrecken sich parallel zum etwa horizontal verlaufenden Schirmrand. Hierdurch ergibt sich vor allem eine materialersparende Komponente. Aber nicht nur der Schirm 13 der Abdeckkappe 11 weist die beschriebenen Stufen 20 auf, sondern auch die traufenseitige Querzone des Domes 2. Die diesbezüglichen Stufen sind mit 21 bezeichnet. Sie setzen sich, wie auch die Stufen 20 der Abdeckkappe 11, in abwärtsgerichtete Abschnitte 20' bzw. 21' fort, welche bis zur Seite der Teile hin abwärtsgerichtet reichen. Im Falle des Domes 2 hat dies den Vorteil, daß durch Sturm hochgetriebenes Wasser gegen die Stufen 21 trifft, welche das Regenwasser dann seitlich ableiten und verhindern, daß es in den Belüftungsspalt 12 respektive in den Bereich des Fensters 14 gerät.As can be seen from the drawing, the shield 13 of the helmet-like cover cap 11, which is formed on the eaves side, is stepped. The individual, essentially equally spaced steps have the reference symbol 20. They extend parallel to the approximately horizontally running screen edge. This primarily results in a material-saving component. But not only the screen 13 of the covering cap 11 has the steps 20 described, but also the transverse zone of the dome 2 on the eaves side. The relevant steps are designated by 21. They continue, like the steps 20 of the cap 11, in downward sections 20 'and 21', which extend down to the side of the parts. In the case of the dome 2, this has the advantage that water driven up by storm hits the steps 21, which then discharge the rain water laterally and prevent it from getting into the ventilation gap 12 or into the area of the window 14.

Fig. 9 gibt nun eine Version an, bei der das Lüftungsanschlußrohr 6 nicht unmittelbar am Dom 2 sitzt, sondern im Interesse eines Neigungsausgleichs an einer auf dem Dom 2 schwenkbeweglich geführten Kappe 22. Entsprechend sitzt auch das Lüftungsgitter 7 in dieser den Dom 2 überfangenden, mit dem Luftanschlußrohr 6 einstückigen Kappe 22. Die Kappe 22 ist wie ein zweiter, kippbeweglich auf dem Dom 2 aufgesetzter Dom mit angeformtem Luftanschlußrohr 6 ausgebildet. Die anderen Bezugziffern sind, ohne textliche Wiederholung, sinngemäß angewandt. Der untere Rand der Kappe ergibt sich aus Fig. 9 in punktierter Linienart und ist mit 23 bezeichnet. Hier sitzt auf Höhe des Radiuspunktes x eine körperliche, horizontale, parallel zur Traufenebene ausgerichtete Klappachse. Gebildet ist diese von der Oberseite einer dem Luftanschlußrohr 6 außenseitig beidseitig angeformten Leiste 24. Der Dom 2 formt an einer Seite eine dem Schwenkwinkelbedarf angepaßte Lagermulde 25 aus. Die entsprechende Zuordnungsart ist im deutschen Patent 25 35 255 des Anmelders erläutert und wird in diesem Umfang hier vollständig in Anspruch genommen. Zur Fixierung der jeweiligen Gebrauchsstellung geht von der einen Seite des Domes unterseitig ein Befestigungslappen 26 aus. Es handelt sich um einen sektoralen Abschnitt mit randseitig liegendem, konzentrisch zu x verlaufenden Bogenschlitz 27. Dieser ist von einer am Luftanschlußrohr 6 sitzenden Klemmschraube 28 durchsetzt. Es kann sich hier um eine Flügelschraube handeln, über die unter Zwischenlage einer Klemmscheibe die jeweilige Stellung fixiert wird. Um den entsprechenden Winkelstellbereich der Kappe 22 noch zu vergrößern, ist die Domzone der Dacheindeckungsplatte 1 firstseitig tiefergezogen. Die entsprechende Einziehung trägt das Bezugszeichen 29, so daß die Kappe 22 dort relativ tief eintauchen kann. Entsprechendes gilt für den dem Schirm 13 abgewandten Endbereich der Abdeckkappe 11, wenn eine solche hier sinnvoll Verwendung hat.9 now specifies a version in which the ventilation connection pipe 6 is not seated directly on the dome 2, but in the interest of compensating for inclination on a cap 22 which is pivotably guided on the dome 2. Accordingly, the ventilation grille 7 is also seated in this, with the air connection tube 6, a one-piece cap 22. The cap 22 is designed like a second dome with a molded-on air connection tube 6, which can be tilted on the dome 2. The other reference numbers are used analogously without repetition of text. The lower edge of the cap results from FIG. 9 in a dotted line and is designated by 23. At the level of the radius point x there is a physical, horizontal folding axis aligned parallel to the eaves plane. This is formed from the top of a strip 24 formed on both sides of the air connection pipe 6 on the outside. The dome 2 forms on one side a bearing recess 25 which is adapted to the swivel angle requirement. The corresponding type of assignment is explained in the applicant's German patent 25 35 255 and is fully used here to this extent. To fix the respective position of use, a fastening tab 26 extends from the underside of one side of the dome. It is a sectoral section with an arc slot 27 lying on the edge and concentric to x. This is penetrated by a clamping screw 28 seated on the air connection pipe 6. It can be a wing screw, via which the respective position is fixed with the interposition of a clamping washer. In order to increase the corresponding angular adjustment range of the cap 22, the dome zone of the roof covering plate 1 is drawn lower on the ridge side. The corresponding retraction bears the reference number 29, so that the cap 22 can dip relatively deep there. The same applies to the end region facing away from the screen 13 the cap 11, if such has useful use here.

Auch in der beschriebenen Ausbildung unter Verwendung der Kappe 22 ergibt sich höhenmäßig keine ins Gewicht fallende Aufstockung der Einheit Dom/Kappe. Der entsprechende Höhenversatz bewegt sich nämlich nur im Rahmen praktisch der Wandungsdicke der Kappe 22, welche eine entsprechend konturenangepaßte Innenseite besitzt.Even in the embodiment described using the cap 22, there is no significant increase in the height of the dome / cap unit. The corresponding height offset moves only within the framework of the wall thickness of the cap 22, which has a correspondingly contour-matched inside.

Die vom Dom 2 getrennte Ausbildung gemäß Fig. 9 hat den Vorteil, daß von der zeichnerischen Darstellung abweichende, also andere Lüftungsanschloßrohr-Typen mit der Eindeckungsplatte 1 verbunden werden können beispielsweise auch solche mit den Dom 2 erheblich weiter überragenden rohrförmigen Fortsätzen, mit oder ohne endseitiger Lüftungsgitterstruktur und dies auch noch in Schraubversion, wie sie in der DE-OS 36 43 319 der Anmelderin im einzelnen erläutert ist. Das bedeutet, daß keine neuen Grundpfannen-Werkzeuge, die bekanntlich sehr teuer sind, hergestellt werden müssen.9 has the advantage that deviating from the drawing, that is other ventilation connection pipe types can be connected to the roofing plate 1, for example, those with the cathedral 2 projecting tubular extensions, with or without the end Ventilation grille structure and this also in screw version, as explained in detail in DE-OS 36 43 319 of the applicant. This means that no new base pan tools, which are known to be very expensive, have to be manufactured.
