Description

Die Erfindung betrifft eine Dachpfanne mit einem eine Öffnung aufweisenden Grundkörper, wobei die Öffnung von einem Kragen umrandet ist, der auf seiner zur Öffnung weisenden Seite Befestigungselemente aufweist, die mit Gegenbefestigungselementen eines auf die Öffnung aufsetzbaren Aufsatzelementes in eine Befestigungsverbindung treten.The invention relates to a roof tile having a base body having an opening, wherein the opening is bordered by a collar which has fastening elements on its side facing the opening, which enter into a fastening connection with counter-fastening elements of an attachment element which can be placed on the opening.

Eine Dachpfanne mit einem Grundkörper aus Kunststoff, der eine Öffnung aufweist, die von einem Kragen umgeben ist, auf den eine Kuppel eines Lüfterdoms aufsetzbar ist, zeigt die DE 100 22 825 A1 .A roof tile with a base body made of plastic, which has an opening which is surrounded by a collar, on which a dome of a fan dome can be placed, shows the DE 100 22 825 A1 ,

Die DE 10 2006 003 478 A1 beschreibt eine Durchgangspfanne mit einer Öffnung, deren Rand einen Kragen ausbildet, von dessen Innenseite Befestigungselemente abragen, die mit Gegenbefestigungselementen eines auf die Öffnung aufsetzbaren Aufsatzteiles in eine Befestigungsverbindung treten. Der Kragen wird hier von einem Adapterteil ausgebildet, welches einen Umfangsflansch aufweist, der der Kontur der Dachpfanne folgt. Die Verbindung des Adapterteils mit dem Grundkörper erfolgt über Fixierelemente beziehungsweise Klebstoff.The DE 10 2006 003 478 A1 describes a through-socket with an opening whose edge forms a collar, protrude from the inside fasteners that occur with counter-fastening elements of an attachable to the opening attachment part in a mounting connection. The collar is formed here by an adapter part which has a peripheral flange which follows the contour of the roof tile. The connection of the adapter part with the base body via fixing or adhesive.

Die DE 201 17 618 U1 beschreibt eine gattungsgemäße Dachpfanne mit einem Grundkörper, der eine kreisförmige Öffnung aufweist, in der ein gummielastisches Einsatzstück angeordnet ist, welches die Öffnung randseitig abdichtend verschließt, wobei aus einer freigespannten, membranartigen Basisebene zwei oval trapezförmige Sockel abragen, die konusförmige Durchgangstüllen ausbilden.The DE 201 17 618 U1 describes a generic roof tile with a base body having a circular opening in which a rubber-elastic insert is arranged, which closes the opening edge sealingly, protrude from a free, membrane-like base plane two oval trapezoidal base forming the cone-shaped grommets.

Die DE 10139 225 A1 beschreibt eine Dacheindeckungsplatte mit einem Durchtrittsloch für ein Lüfterrohr. Eine das Lüftungsrohr tragende Haube sitzt schwenkbeweglich auf einem materialeinheitlich einem Grundkörper angeformten Dom.The DE 10139 225 A1 describes a roofing plate with a passage hole for a fan tube. A hood carrying the ventilation pipe is seated pivotally mounted on a uniform material of a main body dome.

Der Erfindung liegt die Aufgabe zugrunde, eine einfach zu fertigende Durchgangspfanne anzugeben, deren Kragen mit einem Aufsatzelement verbindbar ist.The invention has for its object to provide an easy-to-make through-socket whose collar is connectable with a top element.

Gelöst wird die Aufgabe durch die in den Ansprüchen angegebene Erfindung.The object is achieved by the invention specified in the claims.

Der Kragen weist erfindungsgemäß ein insbesondere von einem Ringteil gebildetes Innenteil auf, welches über eine konturfolgende Anlage eines Befestigungsabschnittes des Grundkörpers am Grundkörper befestigt ist. Die konturfolgende Anlage des Befestigungsabschnittes erfolgt auf der von der Öffnung wegweisenden Seite des Innenteils. Dort bildet das Innenteil zumindestens ein Formschlussverbindungselement aus, das mit dem Befestigungsabschnitt in einer Formschlussverbindung steht. Die Formschlussverbindung wird bei der Fertigung des Grundkörpers erreicht. Hierzu wird der Grundkörper im Tiefziehverfahren um das Innenteil herumgeformt. Das Innenteil ist ein Einlegeteil, welches in eine entsprechende Ausnehmung der Tiefziehform eingelegt wird, sodass der den Grundkörper bildende Kunststoff um die Außenseite des Innenteils herumgeformt werden kann. Das Formschlussverbindungsmittel ist bevorzugt ein Steg, bspw. ein Umfangssteg. Dieser hat die Form einer Rippe, die auf der Außenseite des Innenteils entlang läuft. Um diese Rippe schmiegt sich der Befestigungsabschnitt des Grundkörpers, wenn dieser beim Tiefziehen thermoverformt wird. Er bildet dann eine Formschlussverbindungsnut aus, in der der Umfangssteg eingreift. Das Einlegeteil besitzt insbesondere im Bereich des Formschlussverbindungsmittels Entlüftungsbohrungen. Diese Entlüftungsbohrungen fluchten mit Entlüftungsbohrungen der Tiefziehform. Während des Tiefziehens erfolgt durch die Entlüftungsbohrungen her eine Entlüftung, sodass das zufolge Erwärmung plastisch verformbare Material des Grundkörpers sich um das Formschlussverbindungsmittel legt. Der Befestigungsabschnitt bildet dadurch einen thermogeformten Hinterschnitt aus, mit dem das Innenteil formschlüssig am Grundkörper befestigt ist und auch eine Versteifung des Kragens ausbildet. Die Tiefziehform besitzt Aussparungen, in die die Rastnasen oder Rastzungen des Einlegeteils eingreifen können. Diese Rastzungen ragen in den freien Querschnitt der Öffnung und können in Rastfenster einer Innenwandung eines Befestigungsflansches des Aufsatzelementes eingreifen, welche Innenwand in die Öffnung hineingesteckt ist. Der Flansch übergreift dabei mit einer Außenwandung den Kragen, sodass der Kragen und insbesondere auch ein Dichtring, der den Kragen umgibt, innerhalb einer Ringnut des Aufsatzelementes liegt. Die Befestigungselemente können Schnappnasen oder Federzungen sein, die elastisch rückstellbar in Richtung aus dem Öffnungsquerschnitt verlagerbar sind und die in Rastfenster einfedern können. Das Tiefziehen erfolgt mit einem noch ungelochten Kunststoffrohling. Dieser wird über das Einlegeteil geformt. Es bilden sich der für eine Dachpfanne typische Wasserfalz und Deckfalz aus. Beim Tiefziehen werden bevorzugt keine Hinterschneidungen der Tiefziehform hintergriffen. Lediglich der Umfangssteg des Einlegeteiles wird vom Grundkörper formschlüssig untergriffen. Dieses wird aber beim Entformen mit aus der Form herausgenommen, sodass die Dachpfanne einfach entformbar ist. Nach dem Abkühlen wird somit das formschlüssig umfasste Einlegeteil zusammen mit der Durchgangspfanne vom Werkzeug entformt. Anschließend erfolgt in den bekannten Arbeitsphasen der Rand- und Lochbeschnitt. Das Innenteil kann in einer ersten Variante der Erfindung von einem schmalen Ringteil ausgebildet sein, welches von einem Randabschnitt des Grundkörpers bereichsweise übergriffen ist. Der in der Draufsicht sichtbare Öffnungsrand wird dann vom Material des Grundkörpers ausgebildet. In einer weiteren Variante ist aber auch vorgesehen, dass das Innenteil einen Dom ausbildet, wie ihn die DE 100 22 825 A1 beschreibt, auf dem die Haube eines Dachlüfters aufgesetzt werden kann. Das Einlegeteil kann nachträglich austauschbar sein, wenn es beispielsweise durch das aufgesetzte Aufsetzteil formschlüssig gehalten ist. Eine Wiederverwertbarkeit der Dachpfanne wird dadurch verbessert, wenn Einlegeteil und Grundkörper aus den gleichen Materialien gefertigt sind. Es zeigen:

According to the invention, the collar has an inner part which is formed in particular by a ring part and which is fastened to the base body via a contour-following contact of a fastening section of the base body. The contour following installation of the attachment portion takes place on the side facing away from the opening side of the inner part. There, the inner part forms at least one positive connection element, which is in a positive connection with the fastening section. The positive connection is achieved in the production of the body. For this purpose, the base body is formed around the inner part by deep drawing. The inner part is an insert part, which is inserted into a corresponding recess of the thermoforming mold, so that the plastic forming the main body can be formed around the outside of the inner part. The form-fitting connection means is preferably a web, for example a peripheral web. This has the shape of a rib that runs along the outside of the inner part. Around this rib nestles the attachment portion of the body when thermoformed during deep drawing. It then forms a positive connection groove in which engages the peripheral ridge. The insert has in particular in the region of the positive connection means vent holes. These vent holes are aligned with vent holes of the thermoforming mold. During the deep drawing, a ventilation takes place through the ventilation holes, so that, as a result of heating, plastically deformable material of the base body settles around the positive connection means. The attachment portion thereby forms a thermoformed undercut, with which the inner part is positively secured to the base body and also forms a stiffening of the collar. The thermoforming mold has recesses into which the detents or locking tongues of the insert can engage. These locking tongues protrude into the free cross section of the opening and can in latching window an inner wall of a mounting flange engage the attachment element, which inner wall is inserted into the opening. The flange engages over the collar with an outer wall, so that the collar and in particular also a sealing ring which surrounds the collar lies within an annular groove of the attachment element. The fastening elements may be snap-in lugs or spring tongues which are elastically displaceable in the direction from the opening cross-section and which can deflect into latching windows. The deep drawing is done with a still unperforated plastic blank. This is formed by the insert. It form the typical of a roofing Wasserfalz and Deckfalz. When thermoforming, no undercuts of the thermoforming mold are preferred. Only the peripheral ridge of the insert is engaged by the body in a form-fitting manner. However, this is taken out during demolding with out of the mold, so that the roof tile is easily demoulded. After cooling, thus the form-fitting covered insert is removed from the mold together with the through-socket. Subsequently, in the known working phases of the edge and Lochbeschnitt. The inner part may be formed in a first variant of the invention of a narrow ring part, which is overlapped by an edge portion of the base body partially. The visible in plan view opening edge is then formed by the material of the body. In a further variant, however, it is also provided that the inner part forms a dome, as the DE 100 22 825 A1 describes on which the hood of a roof vent can be placed. The insert may be subsequently interchangeable, if it is held positively, for example, by the patch attachment part. A recyclability of the roof tile is thereby improved when insert and body are made of the same materials. Show it:

Die Durchgangspfanne besteht aus einem Grundkörper 1, der im Tiefziehverfahren gefertigt ist. Hierzu wird eine Tiefziehform 30 (vgl. Fig. 3, 4, 5) verwendet, die die Negativform der Unterseite der Durchgangspfanne ausbildet. Die Tiefziehform 30 besitzt einen Formabschnitt 31, der gegenüber dem umgebenden Bereich der Form hervorragt und der eine Ringstufe 32 ausbildet, in die ein Einlegeteil 10 eingelegt werden kann. Da das Einlegeteil 10 hinterschnittene Elemente aufweist, besitzt die Tiefziehform 30 Aussparungen 33, in die die hinterschnittenen Elemente des Einliegeteiles 10 eintreten können. Bei den hinterschnittenen Elementen handelt es sich um Rastzungen 12.The passage ladle consists of a base body 1, which is manufactured by deep drawing. For this purpose, a thermoforming mold 30 (see. Fig. 3 . 4 . 5 ), which forms the negative mold of the underside of the passage ladle. The thermoforming mold 30 has a mold portion 31 which protrudes from the surrounding area of the mold and forms an annular step 32 into which an insert 10 can be inserted. Since the insert 10 has undercut elements, the thermoforming mold 30 has recesses 33 into which the undercut elements of the inlet part 10 can enter. The undercut elements are locking tongues 12.

Das Einlegeteil 10 ist ein aus Kunststoff gefertigter Ring. Das Einlegeteil 10 kann im Spritzgussverfahren hergestellt werden. Im Ausführungsbeispiel ist das Einlegeteil 10 ein schmaler Ring mit einem ovalen Grundriss. Das Einlegeteil 10 begrenzt eine Öffnung 7 und bildet eine zur Öffnung 7 hinweisende Seite und eine von der Öffnung 7 wegweisende Seite aus. Entlang der von der Öffnung 7 wegweisenden Seite bildet das Einlegeteil 10 einen Ringsteg 11 aus, der sich über den gesamten Umfang des Einlegeteiles 10 erstreckt.The insert 10 is a made of plastic ring. The insert 10 can be produced by injection molding. In the exemplary embodiment, the insert 10 is a narrow ring with an oval floor plan. The insert 10 delimits an opening 7 and forms a side facing the opening 7 and a side facing away from the opening 7 side. Along the side facing away from the opening 7 side, the insert 10 forms an annular web 11, which extends over the entire circumference of the insert 10.

Auf der zur Öffnung 7 weisenden Seite befinden sich Rastzungen 12, die in den Öffnungsquerschnitt hineinragen. Die Rastzungen 12 sind in Richtung der Außenseite des Einlegeteiles 10 elastisch ausbiegbar. Die Rastzungen 12 erstrecken sich senkrecht zu einer Ebene, die vom Öffnungsrand des Einlegeteiles 10 definiert ist.On the side facing the opening 7 there are locking tongues 12 which protrude into the opening cross-section. The locking tongues 12 are elastically bendable in the direction of the outside of the insert 10. The locking tongues 12 extend perpendicular to a plane which is defined by the opening edge of the insert 10.

Im Bereich des Ringsteges 11 besitzt das Einlegeteil 10 Entlüftungsbohrungen 13, die mit Entlüftungsbohrungen 34 der Tiefziehform 30 fluchten, wenn das Einlegeteil 10 in eine Ringnische eingelegt worden ist, die von einer Ringstufe 32 ausgebildet ist (vgl. Fig. 4). In diesem Zustand fluchtet die obere Randkante des Einlegeteils 10 mit der ebenen Stirnfläche des Formabschnittes 31.In the region of the annular web 11, the insert 10 has vent holes 13 which are aligned with vent holes 34 of the thermoforming mold 30 when the insert 10 has been inserted into a ring niche formed by an annular step 32 (see. Fig. 4 ). In this state, the upper peripheral edge of the insert 10 is aligned with the flat end face of the mold portion 31st

Bei einer Temperatur, bei der ein den Grundkörper 1 ausbildender Rohling aus Kunststoff plastisch verformbar ist, wird der den Grundkörper 1 ausbildende Rohling über die Tiefziehform 30 tiefgezogen (vgl. Fig. 5). Durch Entlüftungsbohrungen und insbesondere durch die Entlüftungsbohrung 34 beziehungsweise 13 wird der Raum zwischen Unterseite des Rohlings und Tiefziehform 30 evakuiert, sodass sich der thermoverformbare Rohling an die Oberflächenkontur der Tiefziehform 30 und die Oberflächenkontur des in der Tiefziehform 30 einliegenden Ringteils 10 anschmiegt. Der Rohling des Grundkörpers 1 überformt dabei den Öffnungsfreiraum des Einliegeteiles 10 und bildet im Bereich des Ringsteges 11 einen negativen Hinterschnitt in Form einer Formschlussverbindungsnut 5. Dieser Hinterschnitt, also die Formschlussverbindungsnut 5 ist bevorzugt der einzige Hinterschnitt, der beim Tiefziehen entsteht.At a temperature at which a blank of plastic forming the base body 1 is plastically deformable, the blank forming the base body 1 is deep-drawn over the deep-drawing die 30 (cf. Fig. 5 ). By vent holes and in particular by the vent hole 34 and 13, the space between the bottom of the blank and thermoforming mold 30 is evacuated so that the thermoformable blank to the surface contour of the thermoforming mold 30 and the surface contour of the in the thermoforming mold 30th enclosed ring part 10 conforms. The blank of the base body 1 thereby forms the opening clearance of the inlet part 10 and forms in the region of the annular web 11 a negative undercut in the form of a positive connection groove 5. This undercut, so the Formschlussverbindungsnut 5 is preferably the only undercut, which is formed during deep drawing.

Nach dem Erkalten wird der Grundkörper 1 und das von ihm formschlüssig umfasste Einlegeteil 10 aus der Form herausgenommen. Anschließend wird der Rand und wird die Öffnung 7 beschnitten, sodass ein Öffnungsrand 6 des Grundkörpers 1 die Öffnung 7 umgibt. Die fertige Durchgangspfanne ohne aufgesetztes Aufsatzelement zeigt die Figur 6. Eine Durchgangspfanne mit aufgesetztem Dom zeigt die Figur 1. Aus dem in Figur 2 dargestellten Schnitt ist der Querschnitt des gesamten Kragens erkennbar. Der Öffnungsrand 6 liegt beim Ausführungsbeispiel auf der oberen Randkante des Einlegeteils 10 auf. Das Einlegeteil 10 bildet einen Kragen aus, der dem Öffnungsrand der Öffnung 7 folgt.After cooling, the base body 1 and the form-fitting enclosed by him insert 10 is taken out of the mold. Subsequently, the edge and the opening 7 is cut so that an opening edge 6 of the main body 1 surrounds the opening 7. The finished through ladle without attached attachment element shows the FIG. 6 , A Durchgangspanpf with attached Dom shows the FIG. 1 , From the in FIG. 2 The section shown, the cross section of the entire collar is visible. The opening edge 6 is in the embodiment on the upper peripheral edge of the insert 10. The insert 10 forms a collar which follows the opening edge of the opening 7.

Auf diesen Kragen 10 kann ein Aufsatzelement 20 aufgesetzt werden. Beim Aufsatzelement 20 kann es sich um einen Lüfter, eine Kabeldurchführung oder um eine Rohrdurchführung oder um ein anderes am Dach zu befestigendes Aggregat handeln.On this collar 10, an attachment element 20 can be placed. The attachment element 20 may be a fan, a cable feedthrough or a pipe feedthrough or another unit to be fastened to the roof.

Das in den Figuren 1 und 2 dargestellte Aufsatzelement 20 ist ein Dom 25, in dem ein Lüftungsrohr mit einer Haube eingesetzt werden kann. Der Dom 25 ist an der Unterseite eines Befestigungsflansches 26 angeformt. Der Befestigungsflansch 26 besitzt einen Innensteg 23, der in die Öffnung 7 hereinsteckbar ist. Der Innensteg 23 liegt dabei an der Innenwandung des Einlegeteiles 10 an. Der Innensteg 23 besitzt Fenster 24, in die die Rastzungen 12 des Einlegteiles 10 einrasten können, um das Aufsatzelement 20 mit der Durchgangspfanne zu verbinden.That in the FIGS. 1 and 2 shown attachment element 20 is a dome 25, in which a ventilation tube with a hood can be used. The dome 25 is integrally formed on the underside of a mounting flange 26. The mounting flange 26 has an inner web 23 which can be inserted into the opening 7. The inner web 23 rests against the inner wall of the insert 10. The inner web 23 has windows 24 into which the latching tongues 12 of the Einlegteiles 10 engage can to connect the attachment element 20 with the Durchgangspan.

Der Befestigungsflansch 26 überfängt den Kragen und insbesondere den Öffnungsrand 6 sowie einen Abschnitt des Grundkörpers 1 und den damit verbundenen Abschnitt des Einlegeteils 10. Dieser Kragen wird somit von einer Wand 22 des Befestigungsflansches 26 überfangen. Der Kragen liegt in einer von der Wand 22 und dem Innensteg 23 gebildeten Ringnut 21.The mounting flange 26 overhangs the collar and in particular the opening edge 6 and a portion of the base body 1 and the associated portion of the insert 10. This collar is thus covered by a wall 22 of the mounting flange 26. The collar lies in an annular groove 21 formed by the wall 22 and the inner web 23.

In der Ringnut 21 liegt ferner ein Dichtungsring 27, der die Außenwandung des Kragens 10 umgibt. Der Dichtungsring 27 liegt zwischen einem Abschnitt des Grundkörpers 1 und der Wand 22.In the annular groove 21 is also a sealing ring 27 which surrounds the outer wall of the collar 10. The sealing ring 27 is located between a portion of the base body 1 and the wall 22nd

Der nach unten weisende Rand der Wand 22 des Befestigungsflansches 26 kann auf der Außenwandung des die Formschlussverbindungsnut 5 bildenden Bereichs des Befestigungsabschnittes 4 aufliegen. Hierdurch ergibt sich eine Wasserdichtigkeit zwischen Aufsatzelement 20 und Grundkörper 1, da der Befestigungsabschnitt 4 in die Ringnut 21 eingreift und mit einem Dichtring 27 abgedichtet ist.The downwardly facing edge of the wall 22 of the mounting flange 26 can rest on the outer wall of the Formschlussverbindungsnut 5 forming portion of the mounting portion 4. This results in a watertightness between the attachment element 20 and the base body 1, since the attachment portion 4 engages in the annular groove 21 and is sealed with a sealing ring 27.

Es können verschiedenartige Aufsatzelemente 20 mit einem als Standardelement ausgebildeten Einlegeteil 10 verbunden werden.Various attachment elements 20 can be connected to an insert 10 designed as a standard element.
