- the drain channels 27 are seen in cross-section completely limited by the continuous surface layer of the sash seal 12, so that no further measures for sealing the drain channels 27 relative to the core of the sash seal 12 are necessary.
- a weatherproof roof window 1 is achieved, in particular with regard to the tightness and thermal insulation.
- a simple and therefore cost-effective installation of the roof window 1 is possible because the insulating block 18 is integrated into the wing frame seal 12 and thus only the wing frame seal 12 must be attached to the sash 5. This is provided by at least one rear grip connection, which is quick and easy to produce.

Description
Die Erfindung betrifft ein Dachfenster mit einem Blendrahmen und einem bezüglich des Blendrahmens verlagerbaren, eine Verglasung tragenden Flügelrahmen, wobei sich die Verglasung an einem Flügelrahmenholm des Flügelrahmens abstützt, an dem eine Flügelrahmendichtung zur Überbrückung eines zwischen dem Blendrahmen und dem Flügelrahmen vorliegenden Luftspalts angeordnet ist, die bei geschlossenem Dachfenster im Querschnitt gesehen einen Blendrahmenholm des Blendrahmens wenigstens bereichsweise übergreift.The invention relates to a roof window with a frame and with respect to the frame movable, a glazing-bearing sash, wherein the glazing is supported on a sash of the sash, on which a sash seal for bridging an existing between the frame and the sash air gap is arranged, the seen in cross-section with the roof window closed, a frame spar of the frame at least partially overlaps.
Das Dachfenster ist zum Einbau in ein Gebäude, insbesondere in ein Dach des Gebäudes, vorgesehen. Das Dachfenster verfügt über den Blendrahmen, welcher schlussendlich ortsfest bezüglich des Gebäudes befestigt wird, und den Flügelrahmen. Der Flügelrahmen ist bezüglich des Blendrahmens verlagerbar, insbesondere um eine Drehachse drehbar. Hierzu ist der Flügelrahmen vorzugsweise an dem Blendrahmen gelagert. Der Flügelrahmen trägt die Verglasung des Dachfensters. Die Verglasung kann als Einfachverglasung oder als Mehrfachverglasung, insbesondere Doppelverglasung oder Dreifachverglasung, ausgestaltet sein. Die Verglasung ist beispielsweise von Flügelrahmenholmen des Flügelrahmens eingefasst, wobei insbesondere zwei Vertikalholme und zwei Horizontalholme vorgesehen sind. Auch der Blendrahmen verfügt bevorzugt über zwei Vertikalholme und zwei Horizontalholme. Dabei sind jeweils zwei der Holme, also der Flügelrahmenholme oder Blendrahmenholme, miteinander verbunden, insbesondere ist jeder der Vertikalholme mit jedem der Horizontalholme verbunden. Der eingangs bezeichnete Flügelrahmenholm liegt als einer dieser Flügelrahmenholme vor.The roof window is intended for installation in a building, in particular in a roof of the building. The skylight has the frame, which is finally fixed stationary with respect to the building, and the sash. The casement is displaceable with respect to the frame, in particular rotatable about a rotation axis. For this purpose, the casement is preferably mounted on the frame. The sash frame carries the glazing of the skylight. The glazing can be designed as single glazing or as multiple glazing, in particular double glazing or triple glazing. The glazing is enclosed, for example, by wing frame members of the sash, in particular two vertical beams and two horizontal beams are provided. The frame also preferably has two vertical bars and two horizontal bars. In each case, two of the spars, so the sash or leaf frame beams, connected to each other, in particular, each of the vertical beams is connected to each of the horizontal beams. The above-mentioned wing frame spar is present as one of these wing frame spars.
Der Flügelrahmenholm kann als Kunststoffhohlprofil oder als Holzprofil ausgebildet sein beziehungsweise ein solches aufweisen. In ersterem Fall liegt das Dachfenster insoweit als Kunststoffdachfenster, in letzterem Fall als Holzdachfenster vor. Das Kunststoffhohlprofil wird beispielsweise durch Extrudieren oder dergleichen und anschließendes Ablängen hergestellt. Bevorzugt bestehen mehrere der Flügelrahmenholme aus einem identischen Kunststoffhohlprofil beziehungsweise Holzprofil. Beispielsweise sind die Vertikalholme aus dem gleichen Kunststoffhohlprofil beziehungsweise Holzprofil und/oder die Horizontalholme aus dem gleichen Kunststoffhohlprofil beziehungsweise Holzprofil hergestellt. Es kann jedoch auch vorgesehen sein, dass wenigstens einer der Horizontalholme das gleiche Kunststoffhohlprofil beziehungsweise Holzprofil aufweist wie die Vertikalholme beziehungsweise aus diesem besteht. Das Kunststoffhohlprofil weist wenigstens eine Hohlkammer, vorzugsweise eine Vielzahl von Hohlkammern auf, welche von Versteifungsstegen voneinander getrennt sind. Mit einer derartigen Ausgestaltung des Kunststoffhohlprofils kann eine hohe Steifigkeit bei gleichzeitig geringem Gewicht erzielt werden. Das Holzprofil ist dagegen bevorzugt massiv ausgestaltet.The wing frame spar can be designed as a hollow plastic profile or as a wooden profile or have such. In the former case, the roof window is insofar as a plastic roof window, in the latter case as a wooden roof window. The hollow plastic profile is produced, for example, by extrusion or the like and subsequent cutting to length. Preferably, several of the wing frame spars consist of an identical plastic hollow profile or wood profile. For example, the vertical bars made of the same plastic hollow profile or wooden profile and / or the horizontal bars made of the same plastic hollow profile or wooden profile. However, it can also be provided be that at least one of the horizontal beams has the same plastic hollow profile or wooden profile as the vertical beams or consists of this. The plastic hollow profile has at least one hollow chamber, preferably a plurality of hollow chambers, which are separated from one another by stiffening webs. With such a configuration of the hollow plastic profile high rigidity can be achieved with low weight. By contrast, the wood profile is preferably solid.
Es kann vorgesehen sein, dass sich die Verglasung des Dachfensters senkrecht zu einer Verglasungsebene der Verglasung an dem Flügelrahmenholm abstützt. Die Verglasungsebene wird von der Verglasung definiert. Sie verläuft vorzugsweise parallel zu wenigstens einer Glasscheibe der Verglasung, insbesondere zu allen Glasscheiben der Verglasung. Unter der Verglasungsebene im Rahmen dieser Beschreibung sind auch zu der eigentlichen Verglasungsebene parallele Ebenen zu verstehen. Die Verglasung kann sich direkt an dem Flügelrahmenholm abstützen, sodass also die Verglasung unmittelbar an dem Flügelrahmenholm anliegt. Auch ein indirektes Abstützen der Verglasung an dem Flügelrahmenholm kann jedoch vorgesehen sein. In diesem Fall ist zwischen dem Flügelrahmenholm und der Verglasung ein Stützelement angeordnet.It can be provided that the glazing of the roof window is supported perpendicular to a glazing plane of the glazing on the sash spar. The glazing plane is defined by the glazing. It preferably runs parallel to at least one glass pane of the glazing, in particular to all glass panes of the glazing. The glazing level in the context of this description also means planes parallel to the actual glazing plane. The glazing can be supported directly on the casement spar, so that the glazing rests directly against the casement spar. However, an indirect support of the glazing on the casement spar can also be provided. In this case, a support element is arranged between the casement spar and the glazing.
Das Dachfenster weist zudem die Flügelrahmendichtung auf. Diese ist an dem Flügelrahmenholm des Flügelrahmens angeordnet, insbesondere an diesem befestigt. Die Befestigung der Flügelrahmendichtung an dem Flügelrahmenholm kann formschlüssig, kraftschlüssig und/oder stoffschlüssig erfolgen. Die Flügelrahmendichtung dient der Abdichtung des Dachfensters, sodass ein mittels des Dachfensters abgetrennter Innenraum, insbesondere des Gebäudes, vor Umgebungseinflüssen aus der Außenumgebung geschützt ist. Insoweit dient die Flügelrahmendichtung dazu, eine Innenseite des Dachfensters gegenüber einer Außenseite des Dachfensters abzudichten. Die Flügelrahmendichtung dient dabei dem Abdichten des Flügelrahmens bezüglich des Blendrahmens, insbesondere dem Abdecken und/oder Verschließen des zwischen dem Flügelrahmen und dem Blendrahmen vorliegenden Luftspalts. Die Flügelrahmendichtung erstreckt sich bevorzugt über die gesamte Länge des Flügelrahmenholms in Richtung von dessen Längsmittelachse. Die Flügelrahmendichtung ist bevorzugt im Querschnitt gesehen von der Verglasung beabstandet angeordnet, liegt also nicht an dieser an.The roof window also has the wing frame seal. This is arranged on the sash of the sash, in particular attached to this. The attachment of the wing frame seal on the wing frame spar can be done positively, non-positively and / or cohesively. The sash seal serves to seal the roof window, so that a separated by means of the roof window interior, especially the building, is protected from environmental influences from the outside environment. In that regard, the wing frame seal is used to seal an inner side of the roof window with respect to an outer side of the roof window. The wing frame seal serves to seal the sash frame with respect to the frame, in particular the covering and / or closing of the present between the sash frame and the frame air gap. The wing frame seal preferably extends over the entire length of the wing frame spar in the direction of its longitudinal central axis. The wing frame seal is preferably arranged at a distance from the glazing, viewed in cross-section, and therefore does not rest against it.
Der Flügelrahmenholm und der Blendrahmenholm sind bevorzugt parallel zueinander angeordnet, insbesondere beabstandet parallel zueinander. Um wie vorstehend beschrieben den Luftspalt zwischen dem Blendrahmen und dem Flügelrahmen mittels der Flügelrahmendichtung abzudichten, übergreift diese bei geschlossenem Dachfenster im Querschnitt gesehen den Blendrahmenholm des Blendrahmens wenigstens bereichsweise. Besonders bevorzugt übergreift die Flügelrahmendichtung den Blendrahmenholm vollständig. Insbesondere übergreift sie im Querschnitt gesehen ein an dem Blendrahmen befestigtes Eindeckrahmenblech, welches ansonsten auf einer Dachhaut aufliegt, zumindest bereichsweise. Mit einer derartigen Ausgestaltung des Dachfensters wird eine hervorragende Dichtheit erzielt.The casement spar and the frame spar are preferably arranged parallel to each other, in particular spaced parallel to each other. In order to seal the air gap between the frame and the sash frame by means of the sash seal as described above, this overlaps with the roof window closed when viewed in cross section the frame spar of the frame at least partially. Particularly preferably, the wing frame seal completely overlaps the frame spar. In particular, as seen in cross section, it engages over a roofing sheet metal sheet fastened to the frame, which otherwise rests on a roof skin, at least in regions. With such an embodiment of the roof window excellent tightness is achieved.

Es ist Aufgabe der Erfindung, ein Dachfenster vorzuschlagen, welches gegenüber bekannten Dachfenstern Vorteile aufweist, insbesondere bei gleichbleibend guter Dichtheit des Dachfensters eine hervorragende Wärmedämmung aufweist und zudem kostengünstig herstellbar ist.It is an object of the invention to provide a roof window, which has advantages over known roof windows, in particular with consistently good tightness of the roof window has excellent thermal insulation and is also inexpensive to produce.
Dies wird erfindungsgemäß mit einem Dachfenster mit den Merkmalen des Anspruchs 1 erreicht. Dabei ist vorgesehen, dass ein zwischen dem Blendrahmen und dem Flügelrahmen angeordneter, in den Luftspalt eingreifender Dämmblock zur thermischen Dämmung des Dachfensters integral mit der Flügelrahmendichtung ausgebildet ist, sodass die Flügelrahmendichtung und der Dämmblock als ein gemeinsames Bauteil vorliegen.This is achieved according to the invention with a roof window with the features of claim 1. It is provided that an arranged between the window frame and the sash, engaging in the air gap insulating block for thermal insulation of the roof window is formed integrally with the sash seal, so that the sash seal and the insulating block are present as a common component.
Im Querschnitt durch das Dachfenster bezüglich der Längsmittelachse des Flügelrahmenholms beziehungsweise des Blendrahmenholms liegt der Dämmblock wenigstens bereichsweise, insbesondere vollständig, in dem Luftspalt vor. Dabei ist der Dämmblock an dem Flügelrahmen beziehungsweise dem Flügelrahmenholm befestigt, nämlich zusammen mit der Flügelrahmendichtung, mit welcher er integral ausgeführt ist. Das bedeutet, dass die Flügelrahmendichtung und der Dämmblock als ein gemeinsames Bauteil vorliegen. Sofern im Rahmen dieser Beschreibung nachfolgend auf die Flügelrahmendichtung oder den Dämmblock eingegangen wird, so ist - sofern nichts anderes angegeben ist - stets dieses gemeinsame Bauteil gemeint.In cross-section through the roof window with respect to the longitudinal center axis of the wing frame spar or the frame spar, the insulating block is at least partially, in particular completely, in the air gap. In this case, the insulating block is attached to the sash or the sash, namely together with the sash seal, with which it is integral. This means that the sash seal and the insulating block are present as a common component. Unless otherwise stated in the context of this description, the wing blade seal or the insulating block, it is - unless otherwise stated - always meant this common component.
Bezogen auf eine im Querschnitt vorliegende Überdeckung zwischen Flügelrahmenholm und Blendrahmenholm, unter welcher beispielsweise die maximale Überdeckung der beiden Holme in einer senkrecht auf der Verglasungsebene stehenden Richtung zu verstehen ist, erstreckt sich der Dämmblock beispielsweise um mindestens 10 %, mindestens 20 %, mindestens 25 %, mindestens 30 %, mindestens 40 %, mindestens 50 %, mindestens 60 %, mindestens 70 % oder mindestens 75 % in den Luftspalt hinein beziehungsweise weist mit diesem eine korrespondierende Überdeckung auf. Die Überdeckung des Dämmblocks mit dem Luftspalt wird beispielsweise ausgehend von einer an den Luftspalt angrenzenden Oberkante des Blendrahmenholms oder des Flügelrahmenholms bestimmt.Based on a present in cross-section coverage between casement spar and frame spar, under which, for example, the maximum coverage of the two spars in a direction perpendicular to the glazing plane is to understand the insulating block, for example, by at least 10%, at least 20%, at least 25% , at least 30%, at least 40%, at least 50%, at least 60%, at least 70% or at least 75% in the air gap into or has with this a corresponding overlap. The coverage of the insulating block with the air gap is determined, for example, starting from an adjacent to the air gap upper edge of the frame spar or the wing frame spar.
Bezogen auf die im Querschnitt vorliegende Querschnittsfläche des Luftspalts zwischen dem Blendrahmenholm und dem Flügelrahmenholm weist der in den Luftspalt eingreifende Dämmblock vorzugsweise eine Querschnittsfläche von mindestens 10 %, mindestens 20 %, mindestens 30 %, mindestens 40 % oder mindestens 50 % auf. Der Dämmblock füllt insoweit wenigstens einen Teil des Luftspalts aus, sodass zum einen dessen effektiv verbleibender Querschnitt verringert und zum anderen die Dämmung des Dachfensters deutlich verbessert wird.Based on the cross-sectional cross-sectional area of the air gap between the frame spar and the wing frame spar, the insulating block engaging in the air gap preferably has a cross-sectional area of at least 10%, at least 20%, at least 30%, at least 40% or at least 50%. The insulating block fills so far at least a part of the air gap, so on the one hand effectively reduces its remaining cross-section and on the other the insulation of the roof window is significantly improved.
Aufgrund der integralen Ausgestaltung des Dämmblocks mit der Flügelrahmendichtung wird eine besonders einfache Montage des Dachfensters erzielt, weil lediglich das die Flügelrahmendichtung und den Dämmblock ausbildende gemeinsame Bauteil an dem Flügelrahmenholm befestigt werden muss. Zudem wird durch die integrale Ausgestaltung die Wetterfestigkeit des Dämmblocks deutlich erhöht, weil dieser vorzugsweise analog zu der Flügelrahmendichtung aus einem wetterfesten Material besteht oder zumindest mit einer entsprechenden Oberflächenschicht versehen ist.Due to the integral design of the insulating block with the wing frame seal a particularly simple installation of the roof window is achieved because only the wing frame seal and the insulating block forming common component must be attached to the sash. In addition, the weather resistance of the insulating block is significantly increased by the integral design, because this is preferably analogous to the sash seal from a weatherproof material or at least provided with a corresponding surface layer.
Zusätzlich zu der Flügelrahmendichtung kann eine Glasrahmendichtung vorgesehen sein. Die Glasrahmendichtung dient der Abdichtung der Verglasung gegenüber dem Flügelrahmen beziehungsweise dem Flügelrahmenholm, sodass ein Hindurchtreten von Feuchtigkeit zwischen der Verglasung und dem Flügelrahmenholm mittels der Glasrahmendichtung unterbunden wird. Auch die Glasrahmendichtung erstreckt sich bevorzugt über die gesamte Länge des Flügelrahmenholms in Richtung von dessen Längsmittelachse. Es kann vorgesehen sein, dass die Glasrahmendichtung und die Flügelrahmendichtung integriert ausgeführt sind, also als ein gemeinsames Dichtungselement ausgestaltet sind. Bevorzugt sind jedoch die Glasrahmendichtung und die Flügelrahmendichtung beabstandet voneinander an dem Flügelrahmen angeordnet, insbesondere befestigt. Beispielsweise ist die Glasrahmendichtung zwischen der Verglasung und dem Flügelrahmenholm klemmend gehalten. Insbesondere stützt sich die Verglasung über die Glasrahmendichtung an dem Flügelrahmenholm ab. Im Querschnitt gesehen, also in einem Schnitt senkrecht zu der Längsmittelachse des Flügelrahmenholms und senkrecht auf der Verglasungsebene, liegt die Glasrahmendichtung im Bereich der Verglasung vor, wird also von der Verglasung übergriffen.In addition to the sash seal, a glass frame seal may be provided. The glass frame seal is used to seal the glazing relative to the sash or sash so as to prevent moisture from passing between the glazing and sash through the glass frame seal. Also, the glass frame seal preferably extends over the entire length of the wing frame spar in the direction of its longitudinal central axis. It can be provided that the glass frame seal and the wing frame seal are designed to be integrated, that is configured as a common sealing element. Preferably, however, the glass frame seal and the sash seal spaced from each other are arranged on the sash, in particular fixed. For example, the glass frame seal between the glazing and the sash spar is clamped. In particular, the glazing is supported by the glass frame seal on the wing frame spar. Seen in cross section, ie in a section perpendicular to the longitudinal central axis of the sash frame spar and perpendicular to the glazing plane, the glass frame seal is present in the region of the glazing, so it is overlapped by the glazing.
Eine weitere bevorzugte Ausgestaltung der Erfindung sieht vor, dass der Flügelrahmenholm und/oder der Blendrahmenholm als Kunststoffhohlprofil ausgebildet sind/ist. Der Flügelrahmenholm ist als Kunststoffhohlprofil ausgebildet beziehungsweise weist ein solches auf. Das Dachfenster liegt insoweit als Kunststoffdachfenster vor. Das Kunststoffhohlprofil wird beispielsweise durch Extrudieren oder dergleichen und anschließendem Ablängen hergestellt. Bevorzugt bestehen mehrere der Flügelrahmenholme aus einem identischen Kunststoffhohlprofil. Beispielsweise sind die Vertikalholme aus dem gleichen Kunststoffhohlprofil und/oder die Horizontalholme aus dem gleichen Kunststoffhohlprofil hergestellt. Es kann jedoch auch vorgesehen sein, dass wenigstens einer der Horizontalholme das gleiche Kunststoffhohlprofil aufweist wie einer der Vertikalholme beziehungsweise aus dem entsprechend Kunststoffhohlprofil besteht. Das Kunststoffhohlprofil weist wenigstens eine Hohlkammer, vorzugsweise eine Vielzahl von Hohlkammern auf, welche von Versteifungsstegen voneinander getrennt sind. Mit einer derartigen Ausgestaltung des Kunststoffhohlprofils kann eine hohe Steifigkeit bei gleichzeitig geringem Gewicht erzielt werden.A further preferred embodiment of the invention provides that the wing frame spar and / or the frame spar are designed as a plastic hollow profile / is. The wing frame spar is designed as a plastic hollow profile or has such. The roof window is so far as a plastic roof window. The plastic hollow profile is produced, for example, by extrusion or the like and subsequent cutting to length. Preferably, several of the wing frame spars consist of an identical plastic hollow profile. For example, the vertical bars made of the same plastic hollow profile and / or the horizontal bars are made of the same plastic hollow profile. However, it can also be provided that at least one of the horizontal bars has the same plastic hollow profile as one of the vertical bars or consists of the corresponding plastic hollow profile. The Plastic hollow profile has at least one hollow chamber, preferably a plurality of hollow chambers, which are separated from each other by stiffening webs. With such a configuration of the hollow plastic profile high rigidity can be achieved with low weight.
Im Rahmen einer bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass ein Kern der Flügelrahmendichtung aus einem dämmenden Material besteht, der mit einer wetterbeständigen Oberflächenschicht versehen ist. Die Flügelrahmendichtung beziehungsweise das gemeinsame Bauteil verfügt insoweit über den Kern sowie die Oberflächenschicht. Bevorzugt wird der Kern von der Oberflächenschicht vollständig umgriffen, sodass also der Kern vollständig in der Oberflächenschicht eingehüllt ist. Der Kern kann grundsätzlich aus einem beliebigen Material bestehen. Die Oberflächenschicht ist dagegen wetterbeständig ausgestaltet, besteht also vorzugsweise aus einem wetterfesten Material. Unter dem wetterbeständigen beziehungsweise wetterfesten Material wird vorzugsweise ein Material verstanden, welches bei üblichen Umgebungsbedingungen des Dachfensters eine Haltbarkeit aufweist, welche der Lebensdauer des Dachfensters entspricht.In the context of a preferred embodiment of the invention, it is provided that a core of the wing frame seal consists of an insulating material, which is provided with a weather-resistant surface layer. The wing frame seal or the common component has so far on the core and the surface layer. Preferably, the core is completely encompassed by the surface layer, so that the core is completely encased in the surface layer. The core can basically consist of any material. On the other hand, the surface layer is made weather-resistant, that is to say it preferably consists of a weatherproof material. Under the weatherproof or weatherproof material is preferably understood a material which has a durability under normal environmental conditions of the roof window, which corresponds to the life of the roof window.
Eine Weiterbildung der Erfindung sieht vor, dass der Kern aus Kunststoff, insbesondere einem geschäumten Kunststoff, besteht. Mithilfe des Kerns wird vorzugsweise die dämmende Wirkung der Flügelrahmendichtung beziehungsweise des Dämmblocks erzielt. Entsprechend besteht er aus einem Material, welches eine gute Dämmwirkung aufweist. Bevorzugt kommt Kunststoff zum Einsatz, welcher insbesondere geschäumt ist. Der geschäumte Kunststoff kann geschlossenzellig sein. Auch ein offenzelliger geschäumter Kunststoff kann jedoch herangezogen werden, insbesondere weil der Kern mit der Oberflächenschicht versehen ist, welche dann geschlossen beziehungsweise durchgängig ist, also porenfrei ausgestaltet ist. Als Kunststoff kommt beispielsweise Polyethylen (PE) oder thermoplastisches Polyethylen (TPE) zum Einsatz. Auch andere Kunststoffe sind jedoch verwendbar.A further development of the invention provides that the core consists of plastic, in particular a foamed plastic. By means of the core, the insulating effect of the wing frame seal or the insulating block is preferably achieved. Accordingly, it consists of a material which has a good insulating effect. Preferably plastic is used, which is foamed in particular. The foamed plastic can be closed-celled. However, an open-cell foamed plastic can also be used, in particular because the core is provided with the surface layer, which is then closed or continuous, that is, designed without pores. The plastic used is, for example, polyethylene (PE) or thermoplastic polyethylene (TPE). However, other plastics are usable.
Der Kern der Flügelrahmendichtung liegt vorzugsweise nicht nur in dem Bereich des Dämmblocks vor, sondern auch in jedem Bereich, welcher üblicherweise die Funktionalität der Flügelrahmendichtung bereitstellt. Analog zu den Ausführungen für diese gilt also bevorzugt für den Kern, dass dieser den Luftspalt im Querschnitt gesehen wenigstens bereichsweise, vorzugsweise vollständig übergreift und auch in diesen eingreift. Das bedeutet beispielsweise, dass sich der Kern im Querschnitt gesehen von dem Flügelrahmenholm bis hin zu dem Blendrahmenholm erstreckt beziehungsweise jeweils zu diesen in Überdeckung steht und zwischen Flügelrahmenholm und Blendrahmenholm eingreift.The core of the sash seal is preferably not only in the area of the insulating block, but also in each area, which usually provides the functionality of the sash seal. Analogous to the explanations for these, it is thus preferred for the core that the latter, viewed in cross-section, overlaps and at least partially overlaps the air gap, at least in regions. This means, for example, that the core seen in cross-section of the casement spar up to the frame spar extends or in each case is in overlap and engages between sash and spar frame.
Eine weitere Ausführungsform der Erfindung sieht vor, dass die Oberflächenschicht aus demselben Material besteht wie der Kern, insbesondere mittels Oberflächenbehandlung des Kerns ausgebildet ist. Dies ermöglicht eine einfache und kostengünstige Herstellung der Flügelrahmendichtung. Zunächst wird also der Kern ausgebildet, nämlich vorzugsweise aus dem Kunststoff beziehungsweise dem geschäumten Kunststoff. Anschließend wird der Kern oberflächenbehandelt, sodass die wetterbeständige Oberflächenschicht vorliegt. Im Rahmen der Oberflächenbehandlung werden eventuell an der Oberfläche des Kerns vorliegende Poren verschlossen, sodass die durchgehende Oberflächenschicht vorliegt. Die Oberflächenschicht ist vorzugsweise glatt.A further embodiment of the invention provides that the surface layer consists of the same material as the core, in particular by means of surface treatment of the core is formed. This allows a simple and inexpensive production of the wing frame seal. First, therefore, the core is formed, namely preferably made of the plastic or the foamed plastic. Subsequently, the core is surface-treated so that the weather-resistant surface layer is present. As part of the surface treatment, any pores present on the surface of the core are closed, so that the continuous surface layer is present. The surface layer is preferably smooth.
Eine weitere bevorzugte Ausführungsform der Erfindung sieht vor, dass die Oberflächenschicht aus einem anderen Material besteht als der Kern, insbesondere als nach der Herstellung des Kerns auf diesen aufgetragene Oberflächenbeschichtung vorliegt. Während für den Kern ein erstes Material verwendet wird, wird die Oberflächenschicht aus einem von dem ersten Material verschiedenen zweiten Material gebildet. Beispielsweise wird das erste Material derart gewählt, dass eine besonders gute Dämmwirkung erzielt wird, während das zweite Material die Herstellung der wetterbeständigen Oberflächenschicht ermöglicht. Bevorzugt wird zunächst der Kern ausgebildet und anschließend das zweite Material beziehungsweise die Oberflächenbeschichtung auf ihn aufgetragen. Auch dies erfolgt vorzugsweise derart, dass die Oberflächenschicht nachfolgend geschlossen und/oder glatt ist.A further preferred embodiment of the invention provides that the surface layer consists of a different material than the core, in particular when there is a surface coating applied thereto after the production of the core. While a first material is used for the core, the surface layer is formed of a second material different from the first material. For example, the first material is selected such that a particularly good insulating effect is achieved, while the second material enables the production of the weather-resistant surface layer. Preferably, the core is first formed and then the second material or the surface coating applied to him. This, too, preferably takes place in such a way that the surface layer is subsequently closed and / or smooth.
Eine weitere Ausgestaltung der Erfindung sieht vor, dass die Flügelrahmendichtung an einer den Luftspalt begrenzenden Seitenwand des Flügelrahmenholms zumindest bereichsweise anliegt. Vorstehend wurde bereits erläutert, dass sich die Flügelrahmendichtung zur Erzielung der Dämmwirkung nach Art des Dämmblocks in den Luftspalt hinein erstreckt. Dabei stützt sie sich an der Seitenwand des Flügelrahmenholms ab. Auf diese Art und Weise wird eine kippsichere Anordnung der Flügelrahmendichtung an dem Flügelrahmenholm erzielt. Die Seitenwand liegt vorzugsweise im Querschnitt gesehen unterhalb einer Befestigungsnut des Flügelrahmenholms vor, in welcher die Flügelrahmendichtung formschlüssig gehalten ist. In anderen Worten liegt also die Seitenwand im Querschnitt auf der der Verglasung abgewandten Seite der Befestigungsnut vor.A further embodiment of the invention provides that the wing frame seal rests at least partially on a side wall of the wing frame spar bounding the air gap. It has already been explained above that the wing frame seal extends into the air gap to achieve the insulating effect in the manner of the insulating block. It is supported on the side wall of the wing frame spar. In this way, a tilt-proof arrangement of the sash seal is achieved on the casement spar. The side wall is preferably seen in cross section below a mounting groove of the sash, in which the sash seal is held in a form-fitting manner. In other words, therefore, the side wall is in cross section on the side facing away from the glazing side of the mounting groove.
Eine Weiterbildung der Erfindung sieht vor, dass die Flügelrahmendichtung im Querschnitt gesehen ein an dem Blendrahmenholm befestigtes Halteprofil zur Halterung eines Eindeckrahmenblechs an dem Blendrahmen und/oder einen in das Halteprofil eingreifenden Vertikalsteg des Eindeckrahmenblechs übergreift. Das Halteprofil dient der Halterung des Eindeckrahmenblechs. Insbesondere ist das Halteprofil mit dem Flügelrahmenholm beziehungsweise einem an diesem angeordneten Rastprofil verklipsbar. Zur Befestigung des Eindeckrahmenblechs an dem Blendrahmen greift das Eindeckrahmenblech beispielsweise mit seinem Vertikalsteg in das Halteprofil ein.A further development of the invention provides that the sash seal seen in cross-section, engages over a retaining frame attached to the frame spar for holding a Eindeckrahmenblechs on the frame and / or engaging in the holding profile vertical web of the Eindeckrahmenblechs. The retaining profile serves to hold the Eindeckrahmenblechs. In particular, the retaining profile with the wing frame spar or a locking profile arranged on this is verklipsbar. To attach the Eindeckrahmenblechs to the frame, the Eindeckrahmenblech engages, for example, with its vertical web in the holding profile.
Eine weitere bevorzugte Ausführungsform der Erfindung sieht vor, dass die Flügelrahmendichtung bei geschlossenem Dachfenster auf einer Oberseite des Blendrahmenholms und/oder des Halteprofils dichtend aufliegt. Durch das dichte Aufliegen wird die hervorragende Dichtheit des Dachfensters erzielt, insbesondere durch das Verschließen des Luftspalts gegenüber der Außenumgebung. Die Flügelrahmendichtung liegt hierzu bei geschlossenem Dachfenster zumindest bereichsweise auf der Oberseite des Blendrahmenholms oder der Oberseite des Halteprofils auf. Besonders bevorzugt liegt sie sowohl an dem Blendrahmenholm als auch dem Halteprofil an.A further preferred embodiment of the invention provides that the sash seal with a closed roof window sealingly rests on an upper side of the frame spar and / or the holding profile. Due to the tight contact the excellent tightness of the roof window is achieved, in particular by closing the air gap against the outside environment. For this purpose, the wing-frame seal rests, at least in places, on the upper side of the frame-spar or the upper side of the retaining profile when the skylight is closed. Particularly preferably, it rests against both the frame spar and the retaining profile.
Eine Weiterbildung der Erfindung sieht vor, dass die Flügelrahmendichtung in einer Befestigungsnut des Flügelrahmenholms formschlüssig gehalten ist. Die Befestigungsnut erstreckt sich vorzugsweise über die gesamte Längserstreckung des Flügelrahmenholms. Die Befestigungsnut ist bei geschlossenem Dachfenster in Richtung des Blendrahmens geöffnet.A development of the invention provides that the wing frame seal is held in a form-fitting manner in a fastening groove of the wing frame spar. The fastening groove preferably extends over the entire longitudinal extension of the wing frame spar. The mounting groove is open with the roof window closed in the direction of the window frame.
Eine bevorzugte weitere Ausgestaltung der Erfindung sieht vor, dass an dem Flügelrahmenholm wenigstens ein in Richtung der Flügelrahmendichtung vorspringender Abtropfsteg ausgebildet ist. Über den Abtropfsteg wird beispielsweise Feuchtigkeit aus dem Dachfenster, insbesondere von dem Flügelrahmenholm und/oder einem weiteren Flügelrahmenholm, abgeführt. Der weitere Flügelrahmenholm schließt sich dabei an den Flügelrahmenholm an, insbesondere ist er an diesem befestigt. Beispielsweise liegt an dem Flügelrahmenholm und/oder dem weiteren Flügelrahmenholm ein Ablaufkanal vor, der in Richtung des Abtropfstegs geöffnet ist. In dem Ablaufkanal geführte Feuchtigkeit kann insoweit auf den Abtropfsteg fließen, sodass sie von diesem in Richtung der Flügelrahmendichtung geführt ist. Hierzu steht der Abtropfsteg in Richtung der Flügelrahmendichtung vor. Der Abtropfsteg liegt beispielsweise parallel zu der Verglasungsebene des Dachfensters vor. Er kann gegenüber dieser jedoch auch geneigt sein, insbesondere nach unten, ausgehend von dem Flügelrahmenholm also in Richtung des Blendrahmenholms einen größer werdenden Abstand zu der Verglasungsebene aufweisen, sodass die Feuchtigkeit schwerkraftunterstützt abgeführt wird.A preferred further embodiment of the invention provides that at least one in the direction of the wing frame seal projecting Abtropfsteg is formed on the sash. For example, moisture is removed from the roof window, in particular from the casement spar and / or a further casement spar, via the drip web. The further casement spar joins the wing frame spar, in particular it is attached to this. For example, there is a drainage channel on the sash frame spar and / or the further sash frame spar, which is open in the direction of the Abtropfstegs. Moisture guided in the discharge channel can thus flow onto the drip web, so that it is guided by the latter in the direction of the wing frame seal. For this purpose, the Abtropfsteg protrudes in the direction of the wing frame seal. The Abtropfsteg is for example parallel to the glazing level of the roof window. However, it may also be inclined relative to this, in particular downwards, starting from the casement spar so in the direction of the frame spar Have increasing distance to the glazing level, so that the moisture is dissipated gravity assisted.
Eine weitere Ausführungsform der Erfindung sieht vor, dass im Querschnitt gesehen eine Oberseite der Flügelrahmendichtung in Einbaulage durchgehend unterhalb einer Oberseite des Abtropfstegs angeordnet ist, oder dass die Oberseite der Flügelrahmendichtung im Querschnitt gesehen oberhalb der Oberseite des Abtropfstegs vorliegt und in der Flügelrahmendichtung wenigstens ein Ablaufkanal ausgebildet ist, dessen Boden unterhalb einer Oberseite des Abtropfstegs liegt oder mit der Oberseite fluchtet. Die über den Abtropfsteg abzuführende Feuchtigkeit soll insoweit im Querschnitt gesehen von diesem auf die Oberseite der Flügelrahmendichtung gelangen und über die Oberseite abgeführt werden, nämlich in Richtung des Blendrahmenholms beziehungsweise über diesen hinaus. In einer ersten Variante des Dachfensters ist hierbei die Oberseite der Flügelrahmendichtung in Einbaulage durchgehend unterhalb der Oberseite des Abtropfstegs angeordnet, sodass die Oberseite der Flügelrahmendichtung zumindest kein Gefälle in Richtung des Flügelrahmenholms aufweist. Vorzugsweise weist die Oberseite vielmehr ein Gefälle auf, welches von dem Flügelrahmenholm fort gerichtet ist. Bereichsweise kann die Flügelrahmendichtung jedoch auch in Einbaulage des Dachfensters horizontal verlaufen.A further embodiment of the invention provides that viewed in cross section, an upper side of the sash seal in installation position is arranged continuously below an upper side of the Abtropfstegs, or that the top of the sash seal seen in cross-section above the top of the Abtropfstegs and formed in the sash seal at least one drain channel is, whose bottom is below an upper surface of the Abtropfstegs or aligned with the top. The moisture to be dissipated via the Abtropfsteg should see so far seen in cross section of this on the top of the sash seal and be discharged over the top, namely in the direction of the frame spar or beyond this. In a first variant of the roof window in this case the top of the sash seal is arranged in the installed position continuously below the top of the Abtropfstegs, so that the top of the sash seal has at least no slope in the direction of the sash. Rather, the top preferably has a slope that is directed away from the sash spar. In some areas, however, the wing frame seal can also run horizontally in the installation position of the roof window.
In der zweiten Variante des Dachfensters liegt die Oberseite der Flügelrahmendichtung im Querschnitt gesehen oberhalb der Oberseite des Abtropfstegs. Um dennoch das Abführen der Feuchtigkeit zu ermöglichen, ist der wenigstens eine Ablaufkanal in der Flügelrahmendichtung ausgebildet. Vorzugsweise liegen mehrere Ablaufkanäle vor, welche bevorzugt beabstandet parallel zueinander in der Flügelrahmendichtung ausgebildet sind. Beispielsweise durchgreift der Ablaufkanal beziehungsweise jeder der Ablaufkanäle die Flügelrahmendichtung ausgehend von dem Abtropfsteg in Richtung ihres dem Flügelrahmenholm abgewandten Ende vollständig. Der Ablaufkanal wird von einem Boden und Seitenwänden begrenzt, welche von der Flügelrahmendichtung gebildet sind, insbesondere von der Oberflächenschicht der Flügelrahmendichtung. Um das zuverlässige Abführen der Feuchtigkeit zu ermöglichen, soll der Boden nun im Querschnitt gesehen unterhalb der Oberseite des Abtropfstegs angeordnet sein oder zumindest mit der Oberseite des Abtropfstegs fluchten.In the second variant of the roof window, the top of the wing frame seal is seen in cross-section above the top of the Abtropfstegs. In order to still allow the removal of moisture, the at least one drainage channel is formed in the wing frame seal. Preferably, there are a plurality of drainage channels, which are preferably spaced apart parallel to each other in the wing frame seal. For example, the drainage channel or each of the drainage channels completely engages the wing frame seal starting from the Abtropfsteg in the direction of its the Flügelrahmenholm end facing away. The drainage channel is bounded by a bottom and side walls formed by the sash seal, in particular by the surface layer of the sash seal. In order to enable the reliable removal of moisture, the soil should now be arranged below the top of the Abtropfsteg seen in cross-section or at least aligned with the top of the Abtropfstegs.
Im Rahmen einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass der Ablaufkanal durch Umformen der Flügelrahmendichtung, insbesondere durch Prägen, ausgebildet ist. Es kann also vorgesehen sein, die Flügelrahmendichtung zunächst ohne den Ablaufkanal herzustellen, insbesondere den Kern mit der wetterbeständigen Oberflächenschicht zu versehen. Nachfolgend wird die Flügelrahmendichtung derart umgeformt, dass der wenigstens eine Ablaufkanal nachfolgend vorliegt. Dies kann beispielsweise durch Prägen, insbesondere durch Heißprägen, vorgenommen werden.As part of an advantageous embodiment of the invention, it is provided that the flow channel is formed by forming the wing frame seal, in particular by embossing. It can therefore be provided to initially produce the wing frame seal without the drainage channel, in particular to provide the core with the weather-resistant surface layer. following the wing frame seal is reshaped such that the at least one drain channel is present below. This can be done for example by embossing, in particular by hot stamping.
Eine bevorzugte Ausgestaltung der Erfindung sieht vor, dass die Flügelrahmendichtung an einem in dem Luftspalt vorliegenden Stützsteg des Flügelrahmenholms anliegt. Der Stützsteg ist im Querschnitt gesehen vorzugsweise von der Befestigungsnut beabstandet angeordnet. Insbesondere kann der Flügelrahmenholm derart angeordnet sein, dass die Flügelrahmendichtung im Bereich der Befestigungsnut und im Bereich des Stützstegs an ihm anliegt, in einem zwischen der Befestigungsnut und dem Stützsteg liegenden Bereich jedoch von dem Flügelrahmenholm beabstandet angeordnet ist. Hierdurch wird eine zusätzliche Luftkammer gebildet, welche der Isolierung und mithin der Wärmedämmung des Dachfensters dient.A preferred embodiment of the invention provides that the wing frame seal rests against a supporting web of the sash frame spar present in the air gap. The support web is seen in cross-section preferably spaced from the mounting groove. In particular, the casement spar can be arranged such that the casement seal rests against it in the region of the attachment groove and in the region of the support web, but is spaced from the casement spar in a region located between the attachment groove and the support web. As a result, an additional air chamber is formed, which serves for the insulation and thus the thermal insulation of the roof window.
Weiterhin kann es in einer bevorzugten Ausgestaltung der Erfindung vorgesehen sein, dass die Flügelrahmendichtung den Stützsteg zur formschlüssigen Befestigung an dem Flügelrahmenholm mit einem Haltevorsprung untergreift. Der Stützsteg dient insoweit nicht nur dem Abstützen der Flügelrahmendichtung, sondern zusätzlich deren Befestigung. Hierzu verfügt die Flügelrahmendichtung über den Haltevorsprung, welcher zur Befestigung der Flügelrahmendichtung an dem Flügelrahmenholm formschlüssig mit dem Stützsteg zusammenwirkt. Beispielsweise wird zur Montage der Flügelrahmendichtung an dem Flügelrahmenholm zunächst die Flügelrahmendichtung in der Befestigungsnut formschlüssig angeordnet und nachfolgend der Haltevorsprung mit dem Stützsteg verklipst, sodass der Haltevorsprung den Stützsteg hintergreift beziehungsweise untergreift.Furthermore, it may be provided in a preferred embodiment of the invention that the wing frame seal engages under the support bar for positive attachment to the sash with a holding projection. The support bar is used not only to support the wing frame seal, but in addition their attachment. For this purpose, the wing frame seal has the retaining projection, which cooperates with the support web to fasten the wing frame seal on the wing frame spar. For example, for mounting the sash seal on the casement spar first the wing frame seal in the mounting groove is positively arranged and subsequently the retaining projection with the support bar clipped, so that the retaining projection engages behind the support bar or engages.
Schließlich kann im Rahmen einer weiteren Ausführungsform der Erfindung vorgesehen sein, dass die Flügelrahmendichtung einen dem Blendrahmenholm zugewandten planen Oberflächenbereich aufweist, der bei geschlossenem Dachfenster parallel, insbesondere beabstandet parallel, zu einer dem Flügelrahmenholm zugewandten planen Innenfläche des Blendrahmenholms angeordnet ist. Zwischen dem planen Oberflächenbereich der Flügelrahmendichtung und der planen Innenfläche des Blendrahmenholms liegt insoweit im Querschnitt gesehen ein gleichbleibender Abstand vor. Der Abstand ist vorzugsweise derart bemessen, dass ein Öffnen des Dachfensters aus seiner Geschlossenstellung heraus problemlos möglich ist, insbesondere also ohne Kollision zwischen der Flügelrahmendichtung und dem Blendrahmenholm.Finally, it can be provided in the context of a further embodiment of the invention that the wing frame seal facing the frame spar sparing surface area has parallel to the frame frame spar facing flat inner surface of the frame spar is parallel with the roof window closed, in particular spaced. Between the plane surface area of the wing-frame seal and the flat inner surface of the frame-spar, a constant distance is seen in cross-section. The distance is preferably dimensioned such that an opening of the roof window from its closed position is easily possible, in particular without collision between the wing frame seal and the frame spar.

Die
Im Querschnitt gesehen liegt zwischen dem Blendrahmenholm 3 und dem Flügelrahmenholm 5 ein Luftspalt 10 vor, welcher mittels wenigstens einer Dichtung 11 bei geschlossenem Dachfenster 1 abgedichtet sein kann. Um eine besonders hohe Dichtheit des geschlossenen Dachfensters 1 zu erzielen, verfügt dieses über eine Flügelrahmendichtung 12. Diese ist an dem Flügelrahmenholm 5 befestigt, insbesondere formschlüssig. Hierzu verfügt die Flügelrahmendichtung 12 vorzugsweise über einen Formschlussvorsprung 13, der in eine Befestigungsnut 14 des Flügelrahmenholms 5 formschlüssig eingreift. Weiterhin stützt sich die Flügelrahmendichtung 12 an einem Stützsteg 15 des Flügelrahmenholms 5 ab, sodass ein Verkippen unterbunden ist. Im Querschnitt gesehen liegt zwischen der Befestigungsnut 14 und dem Stützsteg 15 eine Nut 16 in dem Flügelrahmenholm 5 vor, welche derart ausgestaltet ist, dass die Flügelrahmendichtung 12 in diesem Bereich nicht an dem Flügelrahmenholm 5 anliegt. Die Flügelrahmendichtung 12 ist in anderen Worten von einem Boden der Nut 16 beabstandet angeordnet.Seen in cross-section is between the
Zur Abdichtung des Dachfensters 1 übergreift die Flügelrahmendichtung 12 im Querschnitt gesehen den Blendrahmenholm 3 des Blendrahmens 2 zumindest teilweise, insbesondere vollständig. Besonders bevorzugt erstreckt sich die Flügelrahmendichtung 12 in die von dem Flügelrahmenholm 5 abgewandte Richtung bis über den Blendrahmenholm 3 hinaus, insbesondere bis über ein an dem Blendrahmenholm 3 befestigtes Halteprofil 17, welches der Halterung eines hier nicht dargestellten Eindeckrahmenblechs für das Dachfenster 1 dient. Zur Halterung des Eindeckrahmenblechs liegt ein Bereich des Eindeckrahmenblechs an einer Dachhaut eines Dachs, in welchem das Dachfenster 1 verbaut ist, an, während ein Vertikalsteg des Eindeckrahmenblechs in das Halteprofil 17 eingreift. Entsprechend ist das Eindeckrahmenblech zwischen dem Halteprofil 17 und der Dachhaut klemmend gehalten.To seal the roof window 1, the
Um neben der guten Dichtheit des Dachfensters 1 auch eine hervorragende Wärmedämmung zu erzielen, ist mit der Flügelrahmendichtung 12 ein Dämmblock 18 integral ausgeführt. Hierzu ist der Dämmblock 18 einstückig mit einem Dichtungsflügel 19 der Flügelrahmendichtung 12 ausgestaltet, welche sich im Querschnitt gesehen von dem Flügelrahmenholm 5 bis mindestens zu dem Blendrahmenholm 3 beziehungsweise bis zu dem dem Flügelrahmenholm 5 abgewandten Ende der Flügelrahmendichtung 12 erstreckt. Der Dichtungsflügel übergreift insoweit im Querschnitt gesehen den Dämmblock 18, vorzugsweise vollständig. In anderen Worten ist der Dämmblock 18 unterhalb des Dichtungsflügels 19 angeordnet.In order to achieve in addition to the good tightness of the roof window 1 and an excellent thermal insulation, an insulating
Der Dämmblock 18 dient der thermischen Dämmung des Dachfensters 1. Entsprechend besteht die Flügelrahmendichtung 12 beziehungsweise ein Kern der Flügelrahmendichtung 12 aus einem dämmenden Material. Der Kern ist mit einer wetterbeständigen Oberflächenschicht versehen. Es kann vorgesehen sein, dass der Kern und die Oberflächenschicht aus demselben Material, insbesondere aus Kunststoff bestehen. Der Kern liegt dabei beispielsweise in Form von geschäumtem Kunststoff vor, während der gleiche Kunststoff zur Ausbildung der Oberflächenschicht geschlossen beziehungsweise glatt auf den Kern aufgebracht ist. Selbstverständlich kann die Oberflächenschicht jedoch auch aus einem anderen Material bestehen als der Kern.The insulating
Vorstehend wurde bereits erläutert, dass die Flügelrahmendichtung 12 zu ihrer Befestigung in die Befestigungsnut 14 eingreift. Dabei liegt sie benachbart zu der Befestigungsnut 14 an einer Seitenwand 20 des Flügelrahmenholms 5 an, welche dem Blendrahmenholm 3 zugewandt ist. Die Seitenwand 20 kann benachbart zu der Nut 16 vorliegen. Insbesondere liegt also die Seitenwand 20 zwischen der Befestigungsnut 14 einerseits und der Nut 16 andererseits vor.It has already been explained above that the
Die Flügelrahmendichtung 12 dient vorzugsweise dem Abführen von Feuchtigkeit aus dem Dachfenster 1 in Richtung der Außenumgebung. Beispielsweise ist in dem Dachfenster 1, insbesondere an dem Flügelrahmenholm 5 und/oder einem weiteren Flügelrahmenholm, welcher an den Flügelrahmenholm 5 angrenzt, ein Ablaufkanal 21 ausgebildet, welcher hier beispielsweise in einer Ablaufschiene 22 vorliegt. In Richtung des Blendrahmenholms 3 schließt im Querschnitt gesehen der Ablaufkanal 21 sich an einem Abtropfsteg 23 des Flügelrahmenholms 5 an. Insoweit kann in dem Ablaufkanal 21 befindliche Feuchtigkeit auf den Abtropfsteg 23 gelangen und von dort auf die Flügelrahmendichtung 12 abgeführt werden. Von der Flügelrahmendichtung 12 wird nun die Feuchtigkeit bis über den Blendrahmenholm 3, insbesondere bis über das Halteprofil 17, geführt. Dort kann es in Richtung der Dachhaut abtropfen.The
Das Abführen der Feuchtigkeit über den Ablaufkanal 21, den Abtropfsteg 23 und die Flügelrahmendichtung 12 ist durch die Pfeile 24 angedeutet. Besonders bevorzugt ist es, wenn wenigstens eine der Glasscheiben 7, 8 und 9 sich im Querschnitt gesehen bis über den Blendrahmenholm 3 erstreckt. In dem hier dargestellten Ausführungsbeispiel ist dies die oberste Glasscheibe 9, welche von dem Flügelrahmenholm 5 beabstandet angeordnet ist. Insbesondere liegt die Glasscheibe 9 über die Glasscheiben 7 und 8 an dem Flügelrahmenholm 5 an. Von der Glasscheibe 9 kann ebenfalls Feuchtigkeit, insbesondere Kondensat, abtropfen, nämlich in Richtung der Flügelrahmendichtung 12. Dies ist durch die Pfeile 25 dargestellt.The removal of moisture via the
Durch die Integration des Dämmblocks 18 in die Flügelrahmendichtung 12 wird eine einstückige Ausgestaltung der Flügelrahmendichtung 12 erzielt, welche aus einem Kern besteht, der von der Oberflächenschicht vollständig und dicht eingefasst ist. Entsprechend ist eine extrem wetterbeständige Ausgestaltung der Flügelrahmendichtung 12 sowie des Dämmblocks 18 realisiert.By integrating the insulating
Die
Es wird deutlich, dass der Boden 28 wiederum im Querschnitt gesehen unterhalb des Abtropfstegs 23, insbesondere unterhalb einer Oberseite des Abtropfstegs 23, liegt. Der Boden 28 ist bezüglich einer Einbaulage des Dachfensters 1 vorzugsweise durchgehend horizontal oder in Richtung des Blendrahmenholms 3 abschüssig angeordnet, sodass Feuchtigkeit durch den Ablaufkanal 27 durch Schwerkrafteinfluss abgeführt werden kann. Der Ablaufkanal 27 ist bevorzugt durch Umformen der Flügelrahmendichtung 12 ausgebildet.It is clear that the bottom 28, viewed in cross-section, again lies beneath the drip-
Zusätzlich oder alternativ kann es vorgesehen sein, dass die Flügelrahmendichtung 12 einen Haltevorsprung 29 aufweist, der zum rastenden Halten der Flügelrahmendichtung 12 an dem Flügelrahmenholm 5 mit dem Stützsteg 15 zusammenwirkt. Insbesondere hintergreift oder untergreift der Haltevorsprung 29 hierzu den Stützsteg 15. Hierdurch wird eine rastende Befestigung der Flügelrahmendichtung 12 an dem Flügelrahmenholm 5 ermöglicht.Additionally or alternatively, it may be provided that the
Die
Mithilfe der beschriebenen Ausgestaltung der Flügelrahmendichtung 12 wird ein besonders wetterfestes Dachfenster 1 erzielt, insbesondere hinsichtlich der Dichtheit sowie der Wärmedämmung. Zudem ist eine einfache und mithin kostengünstige Montage des Dachfensters 1 möglich, weil der Dämmblock 18 in die Flügelrahmendichtung 12 integriert ist und mithin lediglich die Flügelrahmendichtung 12 an dem Flügelrahmenholm 5 befestigt werden muss. Dies ist durch wenigstens eine Hintergriffsverbindung vorgesehen, welche schnell und einfach herstellbar ist.With the described embodiment of the
