Abstract

In the region of the glass rebate (7), there are inserted heat-insulating bars (11, 12) or pieces which extend from the two pane seals (9, 10) of the sash-frame/leaf-frame profile (1) to almost as far as the insulating webs (4) which bound the glass rebate (7). The heat-insulating bars (11, 12) or pieces rest on the profile webs, parallel to the pane borders, such that the glass-rebate cross-section, on the outside of the pane and on the inside of the pane, is bounded essentially by the heat-insulating bars or pieces and the associated glass seals. <IMAGE>

Description

Die Erfindung betrifft einen Rahmen für ein Fenster, eine Tür oder Fassade, dessen Holme aus wärmegedämmten Aluminium-Verbundprofilen bestehen und der einen umlaufenden, von wenigstens einem die Außenschale mit der Innenschale eines jeden Holmes verbindenden Isoliersteg begrenzten Glasfalz aufweist, in den die Ränder einer Scheibe, eines Paneels oder dergleichen eingreifen, welche durch an der Außen- und Innenschale des Verbundprofiles anliegende Dichtungen abgedichtet sind.The invention relates to a frame for a window, a door or facade, the bars of which are made of thermally insulated aluminum composite profiles and which has a circumferential, folded at least one insulating web connecting the outer shell to the inner shell of each bar, into the edges of a pane , engage a panel or the like, which are sealed by seals lying on the outer and inner shell of the composite profile.

Fenster, Türen oder Fassaden dieser Art sind in vielfältigen Ausführungen bekannt. Die Aluminium-Verbundprofile sind dabei stets Hohlprofile, deren Außenschalen mit der Innenschale durch Kunststoff-Isolierstege verbunden sind, um die Wärmeleitfähigkeit herabzusetzen. Es ist von jeher ein Bestreben der Fachwelt, unvermeidbare Wärmeverluste bei den bekannten Rahmenkonstruktionen schrittweise immer weiter herabzusetzen, das heißt, es soll die Wärmedurchgangszahl, der sogenannte k-Wert, verbessert werden. Bei den bekannten Fenster- und Fassadenkonstruktionen ist der Bereich des Glas- bzw. Paneelfalzes stets eine besondere Schwachstelle, durch den Wärmeverluste entstehen, ebenso wie der Mittelfalzbereich zwischen dem Flügel- und Blendrahmen, der zur Erhöhung der Wärmedämmung unter anderem durch eine Mitteldichtung in zwei Kammern unterteilt wird. Dazu besteht die Mitteldichtung aus zwei Mittelstegen, die an aneinander zugewandten Profilstegen des Blend- und Flügelrahmens außenseitig angesetzt und so gestaltet sind, daß sich in der Schließstellung des Flügelrahmens die freien Dichtungsränder gegeneinander abstützen.Windows, doors or facades of this type are known in a variety of designs. The aluminum composite profiles are always hollow profiles, the outer shells of which are connected to the inner shell by plastic insulating bars in order to reduce the thermal conductivity. It has always been the aim of the professional world to gradually reduce the inevitable heat losses in the known frame constructions, which means that the heat transfer coefficient, the so-called k-value, should be improved. In the known window and facade constructions, the area of the glass or panel rebate is always a particular weak point, through which heat losses occur, as is the middle rebate area between the sash and frame, which, among other things, increases the thermal insulation through a center seal in two chambers is divided. For this purpose, the center seal consists of two center webs, which are attached to the facing profile webs of the frame and casement and are designed so that the free sealing edges are supported against each other in the closed position of the casement.

Der Erfindung liegt die Aufgabe zugrunde, eine Tür, ein Fenster oder eine Fassade mit den Merkmalen des Oberbegriffes des Anspruches 1 so weiterzuentwickeln, daß die Wärmeverluste durch eine weitere Herabsetzung der Wärmdurchgangszahl gegenüber den Ausführungen nach dem vorbekannten Stand der Technik auf einen Wert herabgesetzt werden, der insbesondere dem Werkstoff Aluminium oder einem anderen Metall gestattet, den ansonsten verwendeteten Werkstoffen Holz und Kunststoff hinsichtlich seiner Wärmedammungseigenschaften ebenbürtig zu sein, d. h. einen k-Wert von höchstens 2 Watt pro Quadratmeter Kelvin (2 W/m²K) zu erreichen.The invention has for its object to develop a door, a window or a facade with the features of the preamble of claim 1 so that the heat losses by a further reduction in the heat transfer coefficient compared to the designs be reduced to a value according to the known state of the art, which in particular allows the material aluminum or another metal to be on a par with the materials used, wood and plastic, with regard to their thermal insulation properties, i.e. a k value of at most 2 watts per square meter Kelvin ( 2 W / m²K).

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß im Glasfalzbereich des Verbundprofilrahmens die Scheiben- bzw. Paneelränder auf deren Länge zumindest bereichsweise durch Wärmedämmstücke oder -stäbe aus Isoliermaterial abgeschirmt sind, die sich im Glasflazquerschnitt von der inneren oder äußeren Scheibendichtung möglichst nah in Richtung auf den den Glasfalz begrenzenden Isoliersteg des Verbundprofiles erstrecken, derart, daß der Glasfalzquerschnitt scheibenaußen- und scheibeninnenseitig im wesentlichen von den Wärmedämmstücken bzw. -stäben und den zugeordneten Glasdichtungen begrenzt ist. Durch die isolierten Profilstäbe bzw. -stücke wird bei einer Fassade in Form einer Festverglasung oder bei einem Flügelrahmen eines Fensters oder einer Tür der dem Glasfalz zugeordnete Bereich außen- und innenseitig in erheblichem Maß zusätzlich isoliert. Da der als Wärmebrücke wirkende Bereich zwischen den inneren und äußeren Scheibendichtungen und dem diesem Bereich zugewandten Isoliersteg begrenzt wird, kann durch den Vorschlag nach der Erfindung nunmehr bei einer entsprechenden Gestaltung der Wärmedämmstäbe jede der Innenflächen des Glasfalzes sinngemäß zusätzlich mit einer Isolierschicht versehen werden, so daß der Wärmeverlust auch im Glasfalzbereich und damit bei der gesamten Rahmenkonstruktion beträchtlich herabgesetzt wird. Allein durch diese Maßnahme wird die Wärmedurchgangszahl K auf einen Wert gesenkt, der deutlich unter 2,0 W/m²K liegt.This object is achieved in that in the glass rebate area of the composite profile frame, the pane or panel edges are at least partially shielded along their length by thermal insulation pieces or rods made of insulating material, which are as close as possible in the glass flake cross-section from the inner or outer pane seal towards the Extend the glazing rebate insulating web of the composite profile such that the glass rebate cross-section on the inside and outside of the pane is essentially limited by the heat insulation pieces or rods and the associated glass seals. The insulated profile bars or pieces in a facade in the form of fixed glazing or in a casement frame of a window or a door additionally significantly isolate the area assigned to the glass rebate on the outside and inside. Since the area acting as a thermal bridge between the inner and outer window seals and the insulating web facing this area is limited, each of the inner surfaces of the glass rebate can now also be provided with an insulating layer by the proposal according to the invention with a corresponding design of the thermal insulation bars, so that the heat loss in the glazing rebate area and thus in the entire frame construction is considerably reduced. This measure alone lowers the heat transfer coefficient K to a value that is well below 2.0 W / m²K.

Zweckmäßig sind im Glasfalzquerschnitt gesehen jeweils zwei die Längskanten der eingesetzten Scheibe bzw. des Paneels mit Abstand voneinander umgreifende Wärmedämmstäbe oder -stücke angeordnet. Alternativ dazu kann auch ein einstückig ausgebildeter Wärmedämmstab oder ein einstückiges Wärmedämmstück -im Glasfalzquerschnitt gesehen- vorgesehen sein, wobei die dem Glasrandverbund gegenüberliegende Teilflächen des Stabes bzw. Stückes zwecks Bildung einer Wasserableitung und/oder einer Glasfalzbelüftung gegenüber dem Glasrandverbund zumindest bereichsweise zurückversetzt oder mit Bohrungen oder dergleichen Ausnehmungen versehen sind.As seen in the glass rebate cross-section, two heat-insulating bars or pieces are expediently arranged around the longitudinal edges of the pane or panel used, spaced apart from one another. Alternatively, a one-piece thermal insulation rod or a one-piece thermal insulation piece - in the glazing rebate cross-section seen- be provided, the partial surfaces of the rod or piece opposite the glass edge composite being at least partially set back or provided with bores or similar recesses to form a water drainage and / or a glass rebate ventilation with respect to the glass edge composite.

Bei mehrteiligen Wärmedämmstäben bzw. -stücken sind diese vorteilhaft im Querschnitt L- oder winkelförmig ausgebildet. Es wird dadurch erreicht, daß zwischen den Isolierprofilstäben ein ausreichender Freiraum für die Belüftung des Glasfalzes und den Wasserablauf verbleibt.In the case of multi-part thermal insulation bars or pieces, these are advantageously of L-shaped or angular cross section. It is achieved in that there is sufficient space between the insulating profile bars for the ventilation of the glass rebate and the water drain.

Die Wärmedurchgangszahl wird noch weiter herabgesetzt, wenn die Wärmedämmstäbe oder -stücke als auf der Verbundprofillänge in wesentlichen durchlaufende Massivstäbe ausgebildet sind. Dieser Effekt wird noch weiter dadurch verbessert, daß der der äußeren Scheibendichtung zugeordnete Wärmedämmstab bzw. das -stück als Hohlprofil und der der inneren Scheibendichtung zugeordnete Stab bzw. das Stück als Massivteil ausgebildet ist.The heat transfer coefficient is reduced even further if the heat insulation bars or pieces are designed as solid bars running essentially through the length of the composite profile. This effect is further improved in that the heat insulation rod or the piece assigned to the outer window seal is designed as a hollow profile and the rod or the piece assigned to the inner window seal is designed as a solid part.

In weiterer bevorzugter Ausgestaltung des Erfindungsgegenstandes bilden die Scheibendichtungen mit den der gleichen Falzseite zugeordneten Wärmedämmstäben bzw. -stücken jeweils ein einstückiges, vorzugsweise koextrudiertes Kunststoff-Formteil. Zweckmäßig ist der von den Isolierstegen der zugehörigen Verbundprofile begrenzte Hohlraum mit einer thermoplastischen Masse, oder einem Isoliergranulat, oder einem strangförmigen vorgefertigten Formteil wärmedämmend verfüllt.In a further preferred embodiment of the subject of the invention, the window seals each form an integral, preferably co-extruded plastic molded part with the heat insulation bars or pieces assigned to the same fold side. The cavity delimited by the insulating webs of the associated composite profiles is expediently filled with a thermoplastic material, or an insulating granulate, or a strand-shaped, prefabricated molded part.

Zur noch weiteren Verbesserung der Wärmedurchgangszahl wird bei einer Tür oder einem Fenster, bei denen im Mittelfalz zwischen dem Flügelrahmen und dem Blendrahmen eine stegartige Mitteldichtung vorgesehen ist, vorgeschlagen, daß der Mitteldichtung zumindest ein Formteil aus einem wärmedämmenden Werkstoff zugeordnet ist. Die Formteile können entweder einstückig an die Mitteldichtung angeformt, oder gegenüber dieser getrennt ausgebildet sein. Der bzw. die Formteile sind vorzugsweise an den Stegen der Mitteldichtung angesetzt, die am Isoliersteg des zugeordneten Blendrahmens festgelegt ist. Diese Formteile sind sinngemäß wie zusätzliche Profildichtungen zu sehen. Durch diese wird der Wärmefluß zusätzlich erschwert. Um die Wärmedämmwirkung noch weiter zu erhöhen, ist vorgesehen, daß an beiden Seiten der Mitteldichtung je ein Formteil angesetzt ist. Auch der von einem jeweiligen Formteil und der Mitteldichtung begrenzte Hohlraum kann außerdem mit einer wärmedämmenden Masse oder einem Kunststoffstrang ausgefüllt sein.To further improve the heat transfer coefficient in a door or a window in which a web-like central seal is provided in the central rebate between the casement and the window frame, it is proposed that the central seal is assigned at least one molded part made of a heat-insulating material. The molded parts can either be integrally formed on the center seal, or can be formed separately from this. Of the or the molded parts are preferably attached to the webs of the center seal, which is fixed on the insulating web of the assigned frame. These molded parts can be seen in the same way as additional profile seals. This further complicates the heat flow. In order to further increase the thermal insulation effect, it is provided that a molded part is attached to both sides of the center seal. The cavity delimited by a respective molded part and the central seal can also be filled with a heat-insulating compound or a plastic strand.

Bei Türen und Fenstern, bei denen zwei Mitteldichtungen zwischen den Isolierstegen des Blendrahmens und des Flügelrahmens vorgesehen sind, ist nach einem weiteren Merkmal der Erfindung die von den Mitteldichtungen begrenzte Kammer mit einer Wärmedämmasse oder einem isolierenden Strang oder dgl. verfüllt, wodurch die Wärmedurchgangszahl nochmals herabgesetzt wird.For doors and windows in which two center seals are provided between the insulating webs of the frame and the sash frame, the chamber delimited by the center seals is filled with a thermal insulation mass or an insulating strand or the like, which further reduces the heat transfer coefficient becomes.

In Figur 1 und allen anderen Figuren ist der aus einem Flügel- und einem Blendrahmen bestehende Rahmen in Querschnitt dargestellt. Der Flügelrahmen ist aus einem Aluminium-Verbundprofil 1 gefertigt, dessen Außenschale 2 über zwei parallele Isolierstege 3, 4 mit der Innenschale 5 verbunden ist. In das Verbundprofil 1 ist eine Isolierglasscheibe 6 eingesetzt. Der von dem stirnseitigen Rand der Isolierglasscheibe 6 und dem zugewandten Isoliersteg 4 begrenzte Glasfalz ist durch das Bezugszeichen 7 gekennzeichnet. Die Isolierglasscheibe 6 wird durch eine an der Rahmeninnenseite eingerastete Glashalteleiste 8, eine innere Scheibendichtung 10 bzw. ein Vorlegeband und eine äußere Scheibendichtung 9 in bekannter Weise gesichert.In Figure 1 and all other figures, the frame consisting of a sash and a frame is shown in cross section. The casement is made of an aluminum composite profile 1, the outer shell 2 of which is connected to the inner shell 5 via two parallel insulating webs 3, 4. An insulating glass pane 6 is inserted into the composite profile 1. The glass rebate delimited by the front edge of the insulating glass pane 6 and the facing insulating web 4 is identified by the reference number 7. The insulating glass pane 6 is secured in a known manner by means of a glass retaining strip 8 which is engaged on the inside of the frame, an inner pane seal 10 or a covering tape and an outer pane seal 9.

Bei den Ausführungsbeispielen nach den Figuren 1 bis 5 sind in jedem Glasfalz 7 zwei die Längskanten der eingesetzten Isolierglasscheibe 6 umgreifende Wärmedämmstäbe 11, 12 eingesetzt. Diese erstrecken sich von den Scheibenrändern bis zu den diesen zugewandten Innenwandungen der Außenschale 2 bzw. der Glashalteleiste 8, wobei die innerhalb des Glasfalzes 7 liegenden Bereiche durch ihre L- oder winkelförmigen Querschnitte die Stirnränder der Isolierglasscheibe 6 umfassen. In Richtung der Isolierglasscheibe 6 liegen die Wärmedämmstäbe 11, 12 zwischen den Scheibendichtungen 9, 10 und den nächst gelegenen Profilstegen der Außenschale 2 und der Innenschale 5. Dadurch wird der zwischen den Scheibendichtungen 9, 10 und den besagten Profilstegen liegende Bereich durchgehend wärmedämmend abgeschirmt. Die Wärmedämmstäbe 11, 12 können auch einstückig mit etwa U-förmigem Querschnitt (Fig. 4) ausgebildet sein. Dabei ist der untere Verbindungssteg 11 'zweckmäßig im Querschnitt ein wenig abgesetzt, um Platz für eine Belüftung und Wasserableitung im Falzbereich bereitzustellen.In the exemplary embodiments according to FIGS. 1 to 5, two heat insulation bars 11, 12 are used in each glass rebate 7, encompassing the longitudinal edges of the insulating glass pane 6 used. These extend from the pane edges to the inner walls of the outer shell 2 or the glass holding strip 8 facing them, the areas lying within the glass fold 7 encompassing the end edges of the insulating glass pane 6 due to their L-shaped or angular cross sections. In the direction of the insulating glass pane 6, the thermal insulation rods 11, 12 lie between the pane seals 9, 10 and the closest profile webs of the outer shell 2 and the inner shell 5. As a result, the area lying between the window seals 9, 10 and the said profile webs is continuously shielded with heat insulation. The heat insulation bars 11, 12 can also be formed in one piece with an approximately U-shaped cross section (FIG. 4). The lower connecting web 11 'is expediently slightly offset in cross section in order to provide space for ventilation and water drainage in the rebate area.

Der Blendrahmen besteht ebenfalls aus einem Aluminium-Verbundprofil 13. Die Außenschale 14 ist über die Isolierstege 15, 16 mit der Innenschale 17 verbunden. An den einander zugewandten Isolierstegen 3 und 15 des Flügelrahmen- und des Blendrahmenprofils 1 und 13 ragen jeweils die eine Mitteldichtung bildenden Stege 3', 20 vor. Der von dem Isoliersteg 15 abstehende Steg 20 ist in eine am Isoliersteg 15 angeformte, hinterschnittende Nut eingesetzt. Beidseitig der Mitteldichtung 20 liegt an dem Steg des Isoliersteges 15 jeweils ein strangförmiges Formteil 18, 19 an, durch welche die geschlossene Hohlkammern gebildet werden. Aus der Figur 1 ergibt sich, daß die als Profildichtungen wirkenden Formteile 18, 19 den Wärmedurchgang durch den Mittelfalzbereich wesentlich erschweren. Der abgewinkelte, dem Isoliersteg 15 zugewandte Fuß des jeweiligen Formteils 18, 19 erstreckt sich von der hinterschnittenen Nut bis etwa über die gesamte Breite des Isoliersteges 15 und die Höhe der Mitteldichtung 20. Außerdem sind die von den Isolierstegen 3 und 4 des Flügel-Verbundprofiles 1 und die von den Isolierstegen 15, 16 des Blendrahmen-Verbundprofiles 13 sowie den zugeordneten Profilwandungen der Außen- und Innenschalen 2, 5 bzw. 14, 17 begrenzten Hohlräume mit einer wärmedämmenden thermoplastischen Masse oder einem Isoliergranulat oder mit einem strangförmigen Formteil aus isolierenden Material verfüllt. Das Einbringen von Isoliermasse kann erfolgen, nachdem der Flügel- und Blendrahmen bereits fertig montiert ist, indem das Isoliermaterial in Form eines expandierenden Isolierschaumes in thermoplastischem Zustand oder in Form von Isolierflocken oder dergleichen Granulat oder Pulver in Bohrungen eingebracht und die Hohlräume verfüllt werden. Das Einbringen von vorgefertigten strangförmigen Formteilen erfolgt durch Einschieben in die offenen Stirnenden der einzelnen Verbundprofile vor dem Zusammenfügen der Verbundprofile zu einem Rahmen.The frame also consists of an aluminum composite profile 13. The outer shell 14 is connected to the inner shell 17 via the insulating webs 15, 16. On the mutually facing insulating webs 3 and 15 of the casement and window frame profiles 1 and 13, the webs 3 ', 20 forming a central seal each protrude. The web 20 projecting from the insulating web 15 is inserted into an undercut groove formed on the insulating web 15. On both sides of the center seal 20, a strand-shaped molded part 18, 19 lies against the web of the insulating web 15, through which the closed hollow chambers are formed. It can be seen from FIG. 1 that the molded parts 18, 19 acting as profile seals make the heat transfer through the central rebate region considerably more difficult. The angled foot of the respective molded part 18, 19 facing the insulating web 15 extends from the undercut groove to approximately over the entire width of the insulating web 15 and the height of the center seal 20. In addition, those of the insulating webs 3 and 4 of the wing composite profile 1 and the cavities delimited by the insulating webs 15, 16 of the frame composite profile 13 and the associated profile walls of the outer and inner shells 2, 5 and 14, 17 are filled with a thermally insulating thermoplastic composition or an insulating granulate or with a strand-shaped molded part made of insulating material. Insulating material can be introduced after the sash and window frame has already been assembled by inserting the insulating material in the form of an expanding insulating foam in a thermoplastic state or in the form of insulating flakes or similar granules or powder in bores and filling the cavities. Prefabricated strand-shaped molded parts are introduced by pushing them into the open ends of the individual composite profiles before the composite profiles are joined to form a frame.

Bei dem Ausführungsbeispiel nach der Figur 2 ist der an der Innenwandung der Außenschale 2 anliegende Isolierprofilstab 11 im Unterschied zur Figur 1 als Hohlprofil ausgebildet.In the exemplary embodiment according to FIG. 2, the insulating profile rod 11 resting on the inner wall of the outer shell 2 is, in contrast to FIG. 1, a hollow profile.

In der Ausführungsform nach der Figur 3 ist ein Rahmenquerschnitt einer Fassade mit einer Festverglasung dargestellt. In das Verbundprofil 13 des Blendrahmens ist die Isolierglasscheibe 6 eingesetzt. Die Anordnung der Scheibendichtungen 9, 10 sowie der Wärmedämmstäbe bzw. -stücke 11, 12 entspricht denen der Figuren 1 und 2. Die Glashalteleiste 8 ist an die der Form der Außenschale 17 angepaßt.In the embodiment according to FIG. 3, a frame cross section of a facade with fixed glazing is shown. The insulating glass pane 6 is inserted into the composite profile 13 of the frame. The arrangement of the window seals 9, 10 and the heat insulation rods or pieces 11, 12 corresponds to that of Figures 1 and 2. The glass retaining strip 8 is adapted to that of the shape of the outer shell 17.

Das Ausführungsbeispiel nach der Figur 4 unterscheidet sich von den vorangegangenen Figuren im Bereich des Flügelrahmens 1 durch die besonders abgewinkelte Form des Isoliersteges 3, in Verbindung mit dem Anschlag 3' für die Mitteldichtung 20. Im Bereich des Blendrahmen-Verbundprofils 13 ist die feststehende Mitteldichtung 21 als am Isoliersteg 15 eingerasteter Strang ausgebildet. Da der Abstand zur Innenschale 17 geringer ist als zur Außenseite der Außenschale 14 ist der Mitteldichtung 21 nur ein Formteil 21' an der der Innenschale 17 abgewandten Seite zugeordnet. Der von dem Isoliersteg 15 und der Mitteldichtung 21 und dem Formteil 18 begrenzte Hohlraum ist mit einer Masse 22 aus wärmegedämmten Material ausgefüllt, z. B. einem thermoplastischen Isoliermaterial, einem Dämmgranulat oder -pulver oder dgl.The exemplary embodiment according to FIG. 4 differs from the previous figures in the area of the sash frame 1 by the particularly angled shape of the insulating web 3, in connection with the stop 3 'for the center seal 20. In the area of the frame composite profile 13, the fixed center seal 21 formed as a strand engaged on the insulating web 15. Since the distance to the inner shell 17 is less than to the outside of the outer shell 14, only one molded part 21 ′ is assigned to the center seal 21 on the side facing away from the inner shell 17. The cavity delimited by the insulating web 15 and the center seal 21 and the molded part 18 is filled with a mass 22 of thermally insulated material, e.g. B. a thermoplastic insulating material, an insulating granulate or powder or the like.

Bei der Ausführung nach der Figur 5 ist der dem Blendrahmen-Verbundprofil 13 zugewandte Isoliersteg 3' des Flügelrahmen-Verbundprofiles 1 nahe der Rahmenaußenseite gelegen. Gegen dieses parallel zur Außenfläche der Rahmenprofile stehenden Anschlag legt sich das freie Ende der Mitteldichtung 20 an, die am Isoliersteg 15 des Blendrahmen-Verbundprofiles 13 und der Außenschale 14 eingerastet ist. An der gegenüberliegenden Seite ist eine weitere stegartige Mitteldichtung 21 eingeklipst, die in der Schließlage des Flügelrahmens gegen einen Steg 5' der Außenschale 5 des Flügelrahmen-Verbundprofiles 1 anschlägt. In den von den beiden Mitteldichtungen 20, 21 begrenzten Freiraum ist ein Isolierstrang 22 aus einem wärmedämmenden Material eingesetzt. Durch die doppelte Wirkung der beiden Mitteldichtungen 20, 21 wird eine äußerst gute Isolierwirkung im kritischen Mittelfalzbereich zwischen dem Flügel- und Blendrahmen erreicht.In the embodiment according to FIG. 5, the insulating web 3 ′ of the casement composite profile 1 facing the frame composite profile 13 is located close to the outside of the frame. Against this parallel to the outer surface of the frame profiles abuts the free end of the center seal 20, which is engaged on the insulating web 15 of the composite frame profile 13 and the outer shell 14. On the opposite side a further web-like central seal 21 is clipped in, which in the closed position of the casement strikes against a web 5 'of the outer shell 5 of the casement composite profile 1. In the space delimited by the two center seals 20, 21, an insulating strand 22 made of a heat-insulating material is used. The double action of the two center seals 20, 21 results in an extremely good insulating effect in the critical center rebate area between the wing and Frame reached.

Aus der Figur 5 ergibt sich, daß die Scheibendichtung 9 mit dem Profilstab 11 und die Scheibendichtung 10 mit dem Profilstab 12 jeweils ein einstückiges, z. B. koextrudiertes Formteil sein kann. Aus den Figuren 1 bis 3 und Figur 5 ergibt sich weiterhin, daß die Wärmedämmstäbe 11, 12 im Querschnitt so ausgebildet sind, daß die quer zur Scheibenebene stehenden Schenkel sich bis an die äußeren Ränder des Abstandshalterahmens 23 erstrecken, so daß dieser im wesentlichen freibleibt. In nicht näher dargestellter Weise kann die Entwässerung durch Bohrungen im unteren Holm des jeweiligen Rahmens erfolgen. Bei allen Ausführungen ist es sinnvoll, nicht nur die Zwischenräume zwischen den Mitteldichtungen durch Stränge 22 oder dgl. zu verfüllen, sondern gleichermaßen die Hohlräume zwischen den Isolierstegen 3, 4 bzw. 15, 16 auszufüllen.From Figure 5 it follows that the washer seal 9 with the profile rod 11 and the washer seal 10 with the profile rod 12 each in one piece, for. B. can be coextruded molding. From Figures 1 to 3 and Figure 5 it also follows that the heat insulation bars 11, 12 are designed in cross section so that the legs transverse to the plane of the pane extend to the outer edges of the spacer frame 23, so that it remains essentially free. In a manner not shown, the drainage can take place through holes in the lower spar of the respective frame. In all versions, it makes sense not only to fill the spaces between the center seals with strands 22 or the like, but also to fill the cavities between the insulating webs 3, 4 and 15, 16, respectively.

Auch wenn die vorliegende Erfindung ausschließlich im Zusammenhang mit sogenannten Verbindungsprofilen aus Metall beschrieben worden ist, lassen sich das Erfindungsprinzip wie auch die speziellen konstruktiven Merkmale der Ansprüche und der Beschreibung auch bei Fenstern, Türen oder Fassaden aus Holz oder Kunststoff anwenden.Even if the present invention has been described exclusively in connection with so-called connecting profiles made of metal, the principle of the invention as well as the special structural features of the claims and the description can also be applied to windows, doors or facades made of wood or plastic.
