Description

Die Erfindung betrifft einen Dämmrahmen zum Einbau eines Dachflächenfensters in eine schräge Dachkonstruktion umfassend eine Dachabdeckung, eine als Unterstützung dafür dienende Lattenstruktur, eine unterstützende Vorrichtung von Sparren und eine oben auf oder zwischen den Sparren liegende Schalung mit mindestens einer auswendigen wasserdichten Membran und einer Dämmschicht, wobei erwähnter Rahmen Ober-, Unter- und Seitenelemente umfaßt, die im wesentlichen aus gut isolierendem Material ausgestaltet sind, wobei das Dachflächenfenster in der montierten Stellung dazu eingerichtet ist, mit seinem Blendrahmen in Anlage gegen den Dämmrahmen zu kommen, wobei der Rahmen von separaten Rahmenelementen zusammengesetzt ist, und wobei der Rahmen mit Eingriffsmitteln zur Festhaltung des Rahmens an der Dachkonstruktion und/oder des Dachflächenfensters versehen ist.The invention relates to a Dämmrahmen for installation of a roof window in an inclined roof construction comprising a roof cover, serving as a support slat structure, a supporting device of rafters and a lying on top or between the rafters formwork with at least one memorize waterproof membrane and an insulating layer, said mentioned frame comprises top, bottom and side elements, which are configured substantially of highly insulating material, wherein the roof window in the mounted position is adapted to come with its frame in abutment against the Dämmrahmen, the frame composed of separate frame elements is, and wherein the frame is provided with engagement means for holding the frame to the roof structure and / or the roof window.

Beim Einbau von Dachflächenfenstern in schräge Dachkonstruktionen ist es im allgemein von größer Wichtigkeit, daß die wetterschützende und dämmende Funktion der Konstruktion am Übergang zwischen der Blendrahmenkonstruktion des Dachflächenfensters und der umgebenden Dachkonstruktion in größtmöglichem Umfang wieder hergestellt wird.When installing roof windows in sloping roof structures, it is generally of greater importance that the weatherproofing and insulating function of the construction be restored as much as possible at the transition between the window frame construction of the roof window and the surrounding roof structure.

Im Laufe der Zeit ist eine Reihe von an und für sich ausgezeichneten Lösungen zur Beschaffung der notwendigen Abdichtung zwischen einem Dachflächenfenster und einer Dachkonstruktion zuwege gebracht worden, u.a. durch Entwicklung verschiedener Formen von Eindeckungs- und Anschlußkragen, womit das Dachflächenfenster an der Dachabdeckung oder der wasserdichten, wetterschützenden Außenmembran in der Schalung dicht angeschlossen werden kann, wie z.B. aus EP-A-0 726 994, EP-A-0 730 698 und EP-A-0 756 569 bekannt.In the course of time, a number of excellent solutions have been obtained for obtaining the necessary sealing between a roof window and a roof construction, inter alia, by developing various forms of roofing and extension collars, whereby the roof window on the roof covering or the watertight, weatherproof outer membrane in the formwork can be tightly connected, as for example from EP-A-0 726 994, EP-A-0 730 698 and EP-A-0 756 569 known.

Diese bekannten Lösungen haben aber in keinem nennenswerten Grad den Zweck gehabt, eine optimale Isolationsfähigkeit am Übergang zwischen dem Fenster und der Dachkonstruktion wieder herzustellen, und es kommt bei einem Einbau üblich vor, daß Kältebrücken durch die Blendrahmen- und Rahmenelemente des Fensters eine sichtbare Kondensbildung, besonders an den Ecken der Lichtfläche des Fensters, bei großen Temperaturunterschieden veranlassen können.However, these known solutions have not had the purpose to restore an optimal insulating ability at the transition between the window and the roof construction, and it is customary for an installation that cold bridges through the Blendrahmen- and frame members of the window visible condensation, especially at the corners of the light surface of the window, at large temperature differences can cause.

Die Ursachen dafür können in weitem Ausmaß auf die traditionellen handwerksmäßigen Verfahren bei Einbau von Dachflächenfenstern zurückgeführt werden.The reasons for this can be traced to a great extent to the traditional craftsman procedures for installing skylights.

Bei diesen bekannten Verfahren wird zuerst eine Ausmessung der auswendigen Blendrahmenausmaßen des Fensters vorgenommen, worauf in der Dachkonstruktion eine Fensteröffnung von mindestens denselben Abmessungen ausgeschnitten wird, indem Platz dafür frei gehalten werden muß, sodaß der Blendrahmen in die Fensteröffnung zumindest teilweise versenkt werden kann.In these known methods, a measurement of the outer frame dimensions of the window is first made, whereupon a window opening of at least the same dimensions is cut out in the roof construction by free space must be kept free, so that the frame can be at least partially sunk into the window opening.

Nach dem Ausschneiden der Fensteröffnung wird die eigentliche Montage des Fensters durchgeführt, gewöhnlich durch Benutzung einer Anzahl Montagebeschläge, die teils an den Blendrahmen festgemacht werden, teils an Elemente in der Dachkonstruktion, z.B. Sparren oder Latten auf eine solche Weise, daß die Oberseite des Fensters nach der Montage in einer Ebene liegen wird, die mit der Ebene der Außenabdeckung parallel ist und oft darüber liegt.After cutting out the window opening, the actual assembly of the window is carried out, usually by using a number of mounting brackets, which are partly fixed to the frame, and partly to elements in the roof construction, e.g. Rafters or slats in such a way that the top of the window after assembly will lie in a plane which is parallel to the plane of the outer cover and often over it.

Zum Schluß wird eine auswendige Eindeckung des Fensters im Verhältnis zur Dachkonstruktion ausgeführt, um die ursprüngliche "dichte" Dachkonstruktion wieder herzustellen, worauf u.a. eine Wiederherstellung oder eine inwendige Nachdämmung vorgenommen wird, um das Dämmungsmaterial zu ersetzen, das zufolge Ausscheidens der Fensteröffnung mit Übergröße im Verhältnis zum Blendrahmen fehlen sollte. Wenn erwünscht, kann man auch eine Innenabdeckung mit Innenfuttern machen, um einen netten und funktionellen Übergang an der Wandverkleidung des Raumes zu bilden.Finally, a window covering in relation to the roof construction is carried out in order to restore the original "tight" roof construction, whereupon, among other things, a restoration or an internal post-insulation is made to replace the insulating material resulting in the oversized window opening Relationship to the frame should be missing. If desired, one can also make an inner cover with inner liners to form a nice and functional transition to the wall covering of the room.

Aus SE 414 652, CH 674 545, DE 43 04 386 und EP 0 615 037 kennt man Beispiele ganzer Einbaurahmen, die eventuell eine dämmende Wirkung aufweisen können, aber alle dadurch gekennzeichnet sind, daß sie als Unterstützung für den Blendrahmen des Dachflächenfensters dienen, sodaß das Fenster verhältnismäßig hoch oben in der Dachkonstruktion angebracht wird, welches unerwünscht aus dämmungsmässigen, nachfolgend eindeckungsmässigen und/oder ästhetischen Gründen ist.From SE 414 652, CH 674 545, DE 43 04 386 and EP 0 615 037 are known examples of whole mounting frame, which may possibly have an insulating effect, but all characterized in that they serve as support for the frame of the roof window, so that the window is mounted relatively high up in the roof construction, which is undesirable for reasons of insulation, subsequent covering and / or aesthetic reasons.

Zur Beseitigung dieser Schwierigkeiten, die während der Montage entstehen können, darunter Probleme mit korrekter Ausmessung der für das Fenster notwendigen Öffnung in der Dachfläche, mit fehlerhafter Nachdämmung usw., und um ein einfacheres und genaueres Montageverfahren herbeizuschaffen, schlägt man in internationaler Veröffentlichung Nr. WO 98/31896 einen Dämmrahmen, der auch als Montagerahmen des Dachflächenfensters dient, sind Abdeckprofile zur Bildung der Ober- und Unterelemente des Rahmens in fertigen Längen ausgestaltet, und Abdeckprofile für die Seitenelemente des Rahmens sind durch Verkürzung angepaßt, wonach die Rahmenelemente zusammengeschraubt werden. Der derart hergestellte Rahmen wird als Aufmessungsschablone in Verbindung mit dem Ausschneiden der Öffnung in der Dachfläche benutzt und liegt nachfolgend an die Oberseite der untenliegenden Dachkonstruktion mit der mit der Fensteröffnung bündigen Lichtöffnung des Rahmens an. Das Dachflächenfenster wird dann mit seiner Rahmenkonstruktion an die Oberseite des Dämm- und Montagerahmens anliegend montiert.To overcome these difficulties, which may arise during assembly, including problems with correct measurement of the window opening required in the roof, with defective post-insulation, etc., and to provide a simpler and more accurate assembly method, it is suggested in International Publication No. WO 98/31896 a Dämmrahmen, which also serves as a mounting frame of the roof window, cover profiles to form the upper and lower elements of the frame are designed in finished lengths, and cover profiles for the side members of the frame are adapted by shortening, after which the frame members are screwed together. The frame thus produced is used as a Aufmessungsschablone in connection with the cutting of the opening in the roof surface and is subsequent to the top of the underlying roof structure with the flush with the window opening light opening of the frame. The roof window is then mounted with its frame construction to the top of the insulation and mounting frame fitting.

Mit einem solchen Dämm- und Montagerahmen erreicht man ein genaues und schnelles Ausschneiden der Öffnung in der Dachfläche, und der Bedarf an Nachdämmung erübrigt sich. Da der Blendrahmen des Dachflächenfensters auch in dieser Schrift oben auf dem Dämm- und Montagerahmen angeordnet ist, kann man diesen Rahmen nicht unmittelbar in Verbindung mit niedriger in der Dachfläche einzubauenden Dachflächenfenstern benutzen, und die Tatsache, daß der Dämm- und Montagerahmen mindestens zum Teil selbst das Fenster trägt, herbeiführt, daß größere Forderungen zum für den Rahmen benutzte Material gemacht werden.Achieved with such an insulating and mounting frame it is an accurate and fast cutting of the opening in the roof surface, and the need for re-insulation is unnecessary. Since the frame of the roof window is also located in this document on top of the insulation and mounting frame, you can not use this frame directly in conjunction with lower to be installed in the roof surface skylights, and the fact that the insulating and mounting frame at least in part itself carrying the window, causes greater demands to be made of the material used for the frame.

Ein Dämmrahmen des eingangs erwähnten Typs ist aus EP Veröffentlichung Nr. 0 744 512 bekannt, wo die Seitenelemente des Rahmens ein Dämmteil aus hartem Schaummaterial und eine mit dem Dämmteil verbundenen Leiste umfassen, die sich im montierten Zustand mit den Seitenelementen des Rahmens parallel erstreckt. Die Leisten auf den zwei Seitenelementen des Rahmens sind dazu eingerichtet, mit den Enden der abgeschnittenen Konterlatten oberhalb bzw. unterhalb des Fensters zu verbinden, und die Montagewinkel des Fensters sind an der Leiste auf jeder Seite des Fensters befestigt, wobei die Leistenelemente des Dämmrahmens das Gewicht des Fensters auf die Dachkonstruktion übertragen.An insulating frame of the type mentioned in the opening paragraph is known from EP Publication No. 0 744 512, where the side members of the frame comprise a hard foam insulating piece and a bar connected to the insulating piece, which in the assembled state extends parallel with the side members of the frame. The ledges on the two side members of the frame are adapted to connect to the ends of the cut counter battens above or below the window, and the mounting brackets of the window are secured to the ledge on each side of the window, the ledge members of the dunnage frame being the weight of the window transferred to the roof construction.

Deshalb ist der Zweck der Erfindung, einen Dämmrahmen des einleitend erwähnten Typs herbeizuschaffen, der eine mehr flexible Montage und eine größere Auswahl von Materialien erlaubt.Therefore, the purpose of the invention is to provide an insulating frame of the type mentioned in the introduction which allows more flexible mounting and a wider choice of materials.

Diesen Zweck erreicht man mittels eines Dämmrahmens, der dadurch gekennzeichnet ist, daß jedes Rahmenelement einen solchen Querschnitt aufweist, daß der Rahmen über zumindest eine wesentliche Partie seiner Höhenrichtung eine Lichtungsöffnung aufweist, die größer als die auswendigen Blendrahmenabmessungen ist, daß jedes Rahmenelement mindestens teilweise von einem elastischen und/oder flexiblen Material ausgemacht ist, daß jedes Rahmenelement an seiner Oberseite mit einem Versteifungsprofil verbunden ist, und daß die Zusammensetzung der Rahmenelemente zum Dämmrahmen mittels Schnappschlößern vorgesehen ist.This purpose is achieved by means of a Dämmrahmens, which is characterized in that each frame member has a cross section such that the frame over at least a substantial portion of its height direction has a clearing opening, which is larger than the outer frame dimensions is that each frame member is at least partially made of an elastic and / or flexible material, that each frame member is connected at its upper side with a stiffening profile, and that the composition of the frame members is provided to the insulating frame by means of snap locks.

Erstens bei der Ausgestaltung des Dämmrahmens mindestens teilweise von einem elastischen und/oder flexiblen Material, und zweitens bei der Ausgestaltung des Dämmrahmens mit einer Lichtöffnung, sodaß der Rahmen sowohl von Innen als auch von Außen im Verhältnis zur Dachkonstruktion montiert werden kann, aber trotzdem einen großen Teil des Blendrahmens umfassen kann, sodaß die erwünschte dämmende Wirkung erreicht wird, erzielt man genau die gewollte Flexibilität betreffend das Montageverfahren. Da der Rahmen auch nicht auf dem Fenster unterstützend wirkt, kann das Material im Rahmen in verschiedenem Ausmaß variiert werden, sowie es möglich ist, das ganze Fenster niedriger in der Dachkonstruktion zu plazieren. Durch die Sammlung der Rahmenelemente an den Dämmrahmen mittels eines Schnappschloßes erreicht man ein noch größeren Maß von Flexibilität während der Montage, da kein besonderes Werkzeug in Verbindung mit der Sammlung des Rahmens gefordert wird.First, in the design of the Dämmrahmens at least partially of an elastic and / or flexible material, and secondly in the design of the Dämmrahmens with a light opening, so that the frame can be mounted both inside and outside in relation to the roof construction, but still a large Part of the window frame can include, so that the desired insulating effect is achieved, one achieves exactly the desired flexibility in the assembly process. Since the frame also does not support the window, the material in the frame can be varied to varying degrees, as well as making it possible to place the whole window lower in the roof construction. By the collection of the frame members to the insulating frame by means of a snap lock to achieve an even greater degree of flexibility during assembly, since no special tools in connection with the collection of the frame is required.

Vorteilhafte Ausführungsformen der Erfindung sind in den übrigen unselbständigen Ansprüchen angegeben.Advantageous embodiments of the invention are specified in the remaining dependent claims.

Zum Aufbau eines erfindungsgemäßen Dämmrahmens werden gewöhnlich vier Rahmenelemente benutzt, wobei eine rechteckige oder quadratische Ausgestaltung erreicht wird, und wobei die Rahmenelemente vorzugsweise auf eine gegenseitige im wesentlichen gleichartige Weise aufgebaut sind.To build a Dämmrahmens invention four frame elements are usually used, wherein a rectangular or square configuration is achieved, and wherein the frame members are preferably constructed in a mutual substantially similar manner.

Jedes Rahmenelement 1 umfaßt, wie aus Fig. 1 ersichtlich, ein Dämmungsstück 2 und ein mit der Oberseite des Rahmenelementes 1 verbundene Versteifungsprofil 3. Das Dämmungsstück 2 ist aus einem guten Dämmungsmaterial hergestellt, wie einem aufgeschäumten Plastwerkstoff, z.B. Polyethylen, und das Versteifungsprofil 3 ist aus einem Material mit größerer Steife und Stärke, wie z.B. einem Metallmaterial, besonders Stahl, oder einem Plastwerkstoff hergestellt. Jedes Rahmenelement ist also mindestens teilweise von einem elastischen und/oder flexiblen Material ausgemacht. Die Verbindung zwischen dem Dämmungsstück 2 und dem Versteifungsprofil 3 kann beispielweise durch Leimen oder bei formverschließendem Eingriff erledigt werden. Die Materialien im Rahmenelement sind derart gewählt, daß sowohl die Herstellung als auch Fortschaffung des Materials auf umweltfreundliche Weise ausgeführt werden können.Each frame element 1 comprises, as shown in Fig. 1, an insulation piece 2 and a stiffening profile 3 connected to the top of the frame element 1. The insulation piece 2 is made of a good insulating material, such as a foamed plastic material, e.g. Polyethylene, and the stiffening profile 3 is made of a material with greater stiffness and strength, such as. a metal material, especially steel, or a plastic material. Each frame element is thus at least partially made up of an elastic and / or flexible material. The connection between the insulation piece 2 and the stiffening profile 3 can be done, for example, by gluing or with formverschließem intervention. The materials in the frame member are chosen so that both the manufacture and removal of the material can be carried out in an environmentally friendly manner.

Im Unterteil des Rahmenelementes 1 ist das Dämmungsstück 2 mit einer Partie 4 versehen, die im montierten Zustand in die Lichtöffnung hineinragt, die von den über die Partie 4 liegenden Flächen 5 gebildet wird. Die Partie 4 bildet einen Falz 6, der zusammen mit der Fläche 5 in der eingebauten Stellung die Anlageflächen für die Unter- bzw. Außenseite eines Blendrahmenelementes eines Dachflächenfensters darstellen.In the lower part of the frame member 1, the insulation piece 2 is provided with a lot 4, which protrudes in the mounted state in the light opening, which is formed by the area lying over the lot 4 5. The lot 4 forms a fold 6, which together with the surface 5 in the installed position represent the contact surfaces for the bottom or outside of a frame element of a roof window.

Die Rahmenelemente zum Aufbau des Dämmrahmens werden normalerweise zusammen mit dem Dachflächenfenster selbst geliefert, z.B. bei Plazierung der Rahmenelemente oben auf dem Fenster in der Packung in einer der Diagonalrichtungen des Fensters.The frame members for building the Dämmrahmens are normally supplied together with the roof window itself, for example, when placing the frame elements on top of the window in the pack in a the diagonal directions of the window.

In Verbindung mit dem Einbau werden die Rahmenelemente in den Ecksammlungen mittels eines Schnappschloßes gesammelt, dessen ersten Teil als eine Öffnung 3a im Versteifungsprofil 3 ausgestaltet ist, und dessen zweiten Teil von einem nicht gezeigten Zipfel auf einem auch nicht gezeigten Beschlag ausgemacht ist, der hinter dem Versteifungsprofil 3 oder in dessen Umknicken 3b eingeführt wird, und der nachfolgend mit einem angrenzenden Rahmenelement zusammengekoppelt wird. Die Rahmenelemente werden danach zur Bildung des in Fig. 2 gezeigten Dämmrahmens 10 miteinander verbunden. In Fig. 2 ist weiterhin ein Beispiel einer Dachkonstruktion ohne Dachabdeckung gezeigt, die gewöhnlich aus Ziegelstein, Schieferplatten oder ähnlichem Bedachungsmaterial bestehen kann und von einer Struktur getragen wird, die im gezeigten Beispiel aus im rechten Winkel auf die Sparren 12 gelegten Latten 11, und aus mit den Sparren 12 parallel verlaufenden Konterlatten 13 sowie aus Hilfslatten besteht.In connection with the installation, the frame members are collected in the corner collections by means of a snap lock, the first part is designed as an opening 3a in the stiffening profile 3, and the second part is identified by a tip, not shown on a fitting, not shown, behind the Stiffening profile 3 or in its kinking 3b is introduced, and which is subsequently coupled together with an adjacent frame member. The frame members are then connected together to form the insulating frame 10 shown in FIG. In Fig. 2, an example of a roof construction without roof covering is shown, which may usually consist of brick, slates or similar roofing material and is supported by a structure, in the example shown at right angles to the rafters 12 laid battens 11, and from with the rafters 12 parallel counter battens 13 and consists of auxiliary slats.

Ein unter der Lattenstruktur 11, 13, 14 liegender Schalungsaufbau ist im gezeigten Beispiel als eine wasserdichte Membran 15 ausgestaltet, die aus Dachpappe, armierter Kunststoffolie oder Aluminiumfolie bestehen kann und entweder diffusionsdicht, wobei in der Membran geeignete Ventilationseinrichtungen zur Enlüftung der Schalung montiert sind, oder offen für Diffusion von Wasserdampf ausgestaltet werden kann.In the example shown, a formwork construction lying below the lath structure 11, 13, 14 is configured as a watertight membrane 15, which may consist of roofing felt, reinforced plastic foil or aluminum foil and either diffusion-tight, wherein suitable ventilation devices for ventilating the formwork are mounted in the membrane, or open to diffusion of water vapor can be configured.

Der Dämmrahmen 10 ist in einer Öffnung in der Dachkonstruktion plaziert, die auf übliche Weise durch Entfernung von Material in der Dachkonstruktion gebildet ist, und ist mittels Eingriffsmittel daran festgehalten, die in der gezeigten Ausführungsform als hervorragende Flanschpartien 16, 17 ausgestaltet sind, die mit dem Versteifungsprofil auf den Ober- und Unterelementen des Rahmens einstückig sind. Diese Flanschpartien 16, 17 liegen gegen die Hilfslatten 14 über bzw. unter der Öffnung in der Dachkonstruktion an.The Dämmrahmen 10 is placed in an opening in the roof construction, which is formed in a conventional manner by removing material in the roof structure, and is held by means of engagement thereon, which are configured in the embodiment shown as excellent Flanschpartien 16, 17, with the Stiffening profile on the upper and Sub-elements of the frame are integral. These flange portions 16, 17 bear against the auxiliary slats 14 above or below the opening in the roof construction.

Wie in Fig. 3 gezeigt, kann ein Dachflächenfenster 20 nachfolgend in der Öffnung in der Dachkonstruktion angeordnet und von Montierungsbeschlägen in Form von vier Eckbeschlägen 21 von an und für sich bekannter Art unterstützt werden, z.B. wie in DK Patentanmeldung Nr. PA 1997 01483 des Anmelders beschrieben, da die Eckbeschläge 21 gegen die Hilfslatten 14 anliegen. Der Dämmrahmen 10 umschließt in dieser Stellung die Außenseite der Blendrahmenkonstruktion des Dachflächenfensters, wobei eine Isolierung des Fensters erreicht wird.As shown in Fig. 3, a roof window 20 can be subsequently placed in the opening in the roof structure and supported by mounting fittings in the form of four corner fittings 21 of a type known per se, e.g. as described in DK patent application no. PA 1997 01483 of the applicant, since the corner fittings 21 abut against the auxiliary battens 14. The insulating frame 10 encloses in this position, the outside of the frame construction of the roof window, with insulation of the window is achieved.

Nach dieser Phase des Einbaus wird eine Dichte um der Blendrahmen herum auf eine für sich bekannte Weise etabliert.After this phase of installation, a density around the frame is established in a manner known per se.

Statt den Dämmrahmen 10 vor der Auflegung in die Dachöffnung des Fensters 20 zu montieren, kann man bei einer biegbaren Ausgestaltung der Flanschpartien 16, 17 den Blendrahmen 10 aufwärts durch die Öffnung in der Dachfläche von der Innenseite schieben, d.h. von unten.Instead of mounting the insulating frame 10 in the roof opening of the window 20 prior to placement, with a bendable configuration of the flange portions 16, 17, the window frame 10 can be pushed upwardly through the opening in the roof surface from the inside, i. from underneath.

Eine zweite Ausführungsform des Dämmrahmens ist in Fig. 4 gezeigt, wo die Teile mit gleicher oder analoger Funktion im Verhältnis zur in Fig. 1-3 gezeigte Ausführungsform dieselbe Hinweiszahlen mit 100 dazugelegt tragen.A second embodiment of the Dämmrahmens is shown in Fig. 4, where the parts with the same or analogous function in relation to the embodiment shown in FIGS. 1-3 carry the same reference numbers with 100 added.

Die Rahmenelemente 101 sind auf im wesentlich dieselbe Weise wie im vorhergehenden beschrieben ausgestaltet. Die Sammlung zwischen den Rahmenelementen wird mittels Beschläge 130 erledigt, die im Planbild mit den in Fig. 3 gezeigten Eckenbeschlägen 21 auf dem Dachflächenfenster 20 im wesentlichen gleichförmig sind. Wie in Fig. 6 und 7 gezeigt, weist das Beschlag 130 ein erstes Beinelement 131 mit zwei Beinabschnitten 131a, 131b und ein zweites Beinelement 132 auch mit zwei Beinabschnitten 132a, 132b auf. Die zwei Beinelemente 131, 132 sind mittels einer Punktschweißung 133 miteinander verbunden. Im ersten Beinelement 131 sind in jedem Beinabschnitt 131a, 131b zwei Zipfel 134a, 135a zum Eingriff mit entsprechenden Öffnungen im Versteifungsprofil des Rahmenelementes 101 vorgesehen. Zweifellos kann auch nur ein Zipfel zum Eingriff mit einer einzelnen Öffnung vorgesehen sein, die der Öffnung 3a in der in Fig. 1 gezeigten Ausführungsform entspricht, wie in Fig. 5 gezeigt. Weiterhin weist jeder Abschnitt 132a, 132b im zweiten Beinelement 132 einen Schlitz 136a, 136b zur Bildung eines zusätzlichen Zipfels 137a, 137b auf, der zur Einführung unter die Oberseite des Versteifungsprofils hinein oder in ein Umknicken hinein eingerichtet ist, um das Beschlag 130 an jedem Rahmenelement zusätzlich festzuhalten.The frame members 101 are configured in substantially the same manner as described above. The collection between the frame elements is done by means of fittings 130, which in the plan image with the corner fittings 21 shown in Fig. 3 on the roof window 20 is substantially uniform are. As shown in Figs. 6 and 7, the fitting 130 has a first leg member 131 having two leg portions 131a, 131b and a second leg member 132 also having two leg portions 132a, 132b. The two leg members 131, 132 are connected to each other by means of a spot weld 133. In the first leg element 131, two tabs 134a, 135a are provided in each leg section 131a, 131b for engagement with corresponding openings in the stiffening profile of the frame element 101. Of course, it is also possible to provide only one tip for engagement with a single opening corresponding to the opening 3a in the embodiment shown in FIG. 1, as shown in FIG. Furthermore, each portion 132a, 132b in the second leg member 132 has a slot 136a, 136b for forming an additional tab 137a, 137b adapted to be inserted under the top of the stiffener profile or folded over to enclose the bracket 130 on each frame member additionally hold.

Endlich weist der zweite Beinabschnitt einen nach unten ragenden Zipfel 138 auf, der in dieser Ausführungsform das Eingriffsmittel zur Festhaltung des Dämmrahmens 110 am Dachflächenfenster derart ausmacht, daß der Zipfel 138 in eine dazu ausgestaltete Öffnung im Montierungsbeschlag 21 eingreift. Die Zusammenkupplung oder der Eingriff selbst zeigt lautlich an, daß der Dämmrahmen mit dem betreffenden Eckbeschlag verbunden ist.Finally, the second leg portion has a downwardly projecting tip 138, which in this embodiment, the engagement means for holding the Dämmrahmens 110 on the roof window makes such that the tip 138 engages in an opening designed in the mount fitting 21. The mating coupling or the intervention itself indicates soundly that the Dämmrahmen is connected to the relevant corner fitting.

Die Montierung des Dämmrahmens wird dadurch erledigt, daß das Dachflächenfenster in die Öffnung in der Dachfläche plaziert wird, wonach der gesammelte Dämmrahmen 110 von innen nach oben geschoben wird. Nachdem das Eingriffsmittel oder der Zipfel 138 in Eingriff mit der Öffnung im Eckbeschlag 21 in jeder Ecke gebracht worden ist, wird die Partie 104 des Dämmrahmens zurückgeschoben, sodaß sie die Unterseite des Fensterblendrahmens überlappt. Deshalb ist die Partie 104 mit solchen Ausmaßen versehen, daß sie in Kombination bei einer passenden Wahl des isolierenden Materials so elastisch und/oder flexibel ist, daß sie nach unten und nach außen während der Handhabung gebogen werden kann.The mounting of the Dämmrahmens is done by the roof window is placed in the opening in the roof surface, after which the collected Dämmrahmen 110 is pushed from the inside up. After the engagement means or the tip 138 engages the opening in the corner fitting 21 in each Corner has been brought, the portion 104 of the insulating frame is pushed back so that it overlaps the underside of the window frame. Therefore, the portion 104 is provided with such dimensions that in combination with a proper choice of insulating material, it is so elastic and / or flexible that it can be bent downwardly and outwardly during handling.

Es ist sicherlich auch möglich, der Dämmrahmen 110 in die Dachöffnung zu plazieren und danach das Dachflächenfenster zu montieren.It is certainly also possible to place the insulating frame 110 in the roof opening and then to mount the roof window.

Um eine einfache Anpassung des Dämmrahmens 10, 110 an verschiedene Typen von Dachkonstruktionen zu ermöglichen, kann jedes Rahmenelement 1, 101 mit einem Längsschlitz versehen werden, der von der Unterseite ausgeht und sich ein Stück nach oben im Rahmenelement erstreckt. Dieser Schlitz ermöglicht, daß man mit den Händen einen Längsabschnitt des Unterelementes des Rahmenelementes abreißen kann. In den Seitenelementen des Rahmens dient dieses Abreißen als Sicherung von Platz für den Dämmrahmen zwischen den Sparren in der Dachkonstruktion, während es in den Ober- und Unterelementen ermöglicht, daß z.B. ein sehr schräggestelltes Lichtraumprofil benutzt werden kann, und daß das Dämmrahmen zurückgeschoben werden kann, auch wenn die Schalungskonstruktion nicht besonders flexibel ist.In order to enable a simple adaptation of the insulating frame 10, 110 to various types of roof structures, each frame element 1, 101 can be provided with a longitudinal slot which extends from the underside and extends slightly upwards in the frame element. This slot allows one to tear off a longitudinal section of the lower element of the frame element with the hands. In the side elements of the frame, this tearing serves to secure space for the insulating frame between the rafters in the roof structure, while in the upper and lower elements it is possible to make e.g. a very slanted clearance profile can be used, and that the Dämmrahmen can be pushed back, even if the formwork construction is not very flexible.
