Description

Die Erfindung betrifft einen Einsatzrahmen zum Umrüsten eines einfach verglasten Flügelrahmens auf Isolierverglasung, bestehend aus an die Öffnung des Flügelrahmens angepassten, auf Gehrung miteinander verbundenen und, gegebenenfalls zusammen mit der Isolierverglasung, von einer Seite des Flügelrahmens einsetzbaren ersten Profilleisten mit einem L-förmigen Querschnittsbereich, der mit einem Flansch gegen die äussere Umfangsfläche der Isolierverglasung und mit dem anderen Flansch gegen einen Randstreifen der Isolierverglasung anliegt, aus von der anderen Seite her in den Flügelrahmen einsetzbaren zweiten Profilleisten und aus im Querschnitt keilförmigen Füllstücken zum Ausfüllen eines Zwischenraumes zwischen einer abgeschrägten Oberfläche des Flügelrahmens und dem gegen die äussere Umfangsfläche der Isolierverglasung anliegenden Flansch der ersten Profilleisten.The invention relates to an insert frame for converting a single-glazed casement frame to insulating glazing, consisting of miter-fitted first profile strips which are adapted to the opening of the casement frame, are mitred to one another and, optionally together with the insulating glazing, can be inserted from one side of the casement frame, with an L-shaped cross-sectional area, which rests with one flange against the outer circumferential surface of the insulating glazing and with the other flange against an edge strip of the insulating glazing, from second profiled strips which can be inserted into the casement from the other side and from fillers which are wedge-shaped in cross-section for filling an intermediate space between a bevelled surface of the casement and the flange of the first profile strips bearing against the outer peripheral surface of the insulating glazing.

Derartige Einsatzrahmen sind aus der DE-A-26 54 398 des Anmelders bekannt. Sie gestatten eine Umrüstung von Einfachverglasung auf Isolierverglasung, ohne dass es erforderlich ist, den vorhandenen Flügelrahmen oder sogar darüberhinaus den Blendrahmen zu entfernen. Vielmehr wird lediglich die vorhandene Einfachverglasung herausgenommen. Änderungen an Blend- und Flügelrahmen sind nicht erforderlich. Kitt- und Glasreste in dem bei einfach verglasten Flügelrahmen vorhandenen Falz können verbleiben und müssen nicht vollständig entfernt werden.Such insert frames are known from the applicant's DE-A-26 54 398. They allow conversion from single glazing to double glazing without the need to remove the existing casement or even beyond the frame. Rather, the existing single glazing is simply removed. Changes to the frame and sash are not necessary. Remnants of putty and glass in the rebate in the single-glazed casement can remain and do not have to be removed completely.

Neben dem Falz, der sich zumeist auf der Gebäudeaussenseite des Flügelrahmens befindet, weisen herkömmliche Flügelrahmen zumeist eine von dem Falz ausgehende schräg zurücklaufende Querschnittsform auf. Eine ebene Auflagefläche für die ersten und zweiten Profilleisten wird bei den herkömmlichen Einsatzrahmen dadurch geschaffen, dass der Flügelrahmen mit Hilfe der keilförmigen Füllstücke zu einer rechtwinkligen Querschnittsform ergänzt wird. Die üblicherweise aus Holz bestehenden Füllstücke werden mit dem Flügelrahmen und der ersten Profilleiste des Einsatzrahmens verklebt und/oder gemeinsam mit der ersten Profilleiste an den Flügelrahmen angeschraubt. Das Herstellen der Füllstücke mit geeigneter Querschnittsform sowie das Positionieren und Ankleben bzw. Anschrauben der Füllstücke bedingt einen erhöhten Arbeitsaufwand bei der Montage des Einsatzrahmens. Da es aufgrund der Keilform der Füllstücke schwierig ist, die Füllstücke während des Anschraubens an den Flügelrahmen in ihrer korrekten Position zu halten, werden die Füllstücke zumeist zuvor an den Flügelrahmen angeklebt. Da in diesem Fall zunächst das Aushärten des Klebers abgewartet werden muss, ergibt sich eine unerwünschte Verzögerung bei der Montage.In addition to the fold, which is usually located on the outside of the wing frame of the building, conventional wing frames mostly have an obliquely returning cross-sectional shape starting from the fold. In the conventional insert frames, a flat contact surface for the first and second profile strips is created in that the sash frame is supplemented to a rectangular cross-sectional shape with the help of the wedge-shaped filler pieces. The filler pieces usually made of wood are glued to the sash frame and the first profile strip of the insert frame and / or screwed together with the first profile strip to the sash frame. The production of the filler pieces with a suitable cross-sectional shape and the positioning and gluing or screwing of the filler pieces requires an increased amount of work when assembling the insert frame. Since it is difficult due to the wedge shape of the filler pieces to keep the filler pieces in their correct position while screwing them onto the sash frame, the filler pieces are usually glued to the sash frame beforehand. In this case, since the curing of the adhesive must first be waited for, there is an undesirable delay in assembly.

Der Erfindung liegt die Aufgabe zugrunde, einen gattungsgemässen Einsatzrahmen zu schaffen, dessen Profilleisten mit geringerem Arbeits-und Zeitaufwand fest mit dem Flügelrahmen verbindbar sind.The invention has for its object to provide a generic insert frame, the profile strips can be firmly connected to the sash frame with less work and time.

Diese Aufgabe wird erfindungsgemäss bei einem Einsatzrahmen der eingangs genannten Art dadurch gelöst, dass die Füllstücke als dritte Profilleisten mit je einer Längs-Nut angrenzend an den Rand der stärkeren Seite ausgebildet und jeweils mit dem gegen die äussere Umfangsfläche der Isolierverglasung anliegenden Flansch der ersten Profilleiste verrastbar sind und dass die zweiten Profilleisten je einen in die Nut der zugehörigen dritten Profilleiste einschiebbaren Flansch aufweisen, der gegen einen der ersten Profilleisten gegenüberliegenden Randstreifen der Isolierverglasung anliegt.This object is achieved according to the invention in the case of an insert frame of the type mentioned at the outset in that the filler pieces are designed as third profile strips, each with a longitudinal groove adjacent to the edge of the stronger side, and each can be locked with the flange of the first profile strip which bears against the outer peripheral surface of the insulating glazing and that the second profile strips each have a flange which can be inserted into the groove of the associated third profile strip and which bears against an edge strip of the insulating glazing unit lying opposite the first profile strips.

Die erste Profilleiste, die im folgenden als Trägerleiste bezeichnet werden soll, da sie die Isolierverglasung umgibt und abstützt, weist vorzugsweise auf der Aussenfläche des gegen den äusseren Umfang der Isolierverglasung anliegenden Schenkels längs gerichtete Nuten und/oder Rippen auf, die mit entsprechenden Nuten und/oder Rippen auf einer Oberfläche der dritten Profilleiste zusammenwirken und die Verrastung in wenigstens zwei seitlichen Positionen und somit eine Anpassung an unterschiedliche Isolierglasstärken gestatten. Die mit der Trägerleiste verrastbare dritte Profilleiste soll im folgenden als Klemmleiste bezeichnet werden.The first profile strip, which will be referred to below as the carrier strip, since it surrounds and supports the insulating glazing, preferably has longitudinally oriented grooves and / or ribs on the outer surface of the leg abutting against the outer circumference of the insulating glazing, which are provided with corresponding grooves and / or or ribs cooperate on a surface of the third profile strip and allow the locking in at least two lateral positions and thus an adaptation to different insulating glass thicknesses. The third profile bar, which can be locked with the carrier bar, is referred to below as the terminal bar.

Die Montage der Trägerleiste erfolgt derart, dass zunächst die Trägerleiste von der den Falz enthaltenden Aussenfläche des Flügelrahmens eingeschoben wird, bis der die Isolierverglasung umgebende Flansch des im Querschnitt L-förmigen Teilbereichs über der schräg abfallenden Querschnittsfläche des Flügelrahmens liegt. Mit ihren weiteren, später näher erläuterten Profilteilen umgibt dabei die Trägerleiste den Falz mit dort gegebenenfalls verbleibenden Kitt- und Glasresten und schliesst den Flügelrahmen in einer unterhalb des Falzes liegenden Position ab.The support strip is installed in such a way that the support strip is first pushed in from the outer surface of the casement containing the fold until the flange surrounding the insulating glazing of the section L-shaped in cross section lies above the obliquely sloping cross-sectional area of the casement. With its further profile parts, which will be explained in more detail later, the carrier strip surrounds the fold with any cement and glass remnants that may be left there and closes off the casement in a position lying below the fold.

Anschliessend werden von der gegenüberliegenden Seite der Isolierverglasung her die Klemmleiste und die zweite, als Abschlussleiste zu bezeichnende Profilleiste eingeschoben.The terminal strip and the second profile strip, which can be called the end strip, are then inserted from the opposite side of the insulating glazing.

Dabei wird die Klemmleiste unter Einfügung von Klebe- und Dichtmitteln keilförmig in den Zwischenraum zwischen der im Querschnitt schrägen Fläche des Flügelrahmens und dem die Isolierverglasung umgebenden Schenkel der Trägerleiste eingedrückt, bis eine der durch die Rippen und Nuten gebildeten Verrastungen eingreift. Bereits in diesem Zustand liegt der Einsatzrahmen in dem Flügelrahmen fest, ohne dass ein Erhärten des Klebstoffes abgewartet werden müsste.The terminal strip is pressed in a wedge shape with the insertion of adhesive and sealant into the space between the cross-sectionally sloping surface of the casement and the leg of the carrier strip surrounding the insulating glazing until one of the catches formed by the ribs and grooves engages. Even in this state, the insert frame is fixed in the casement frame without waiting for the adhesive to harden.

Die Trägerleiste weist im einzelnen einen Querschnitt auf, der von dem Rand des gegen den Randstreifen der Isolierverglasung anliegenden Schenkels des L-förmigen Querschnittsbereichs spitzwinklig zurückläuft und sodann zur Bildung eines äusseren Abdeckflansches entsprechend stumpfwinklig abgewinkelt ist.In detail, the carrier strip has a cross section which runs back at an acute angle from the edge of the leg of the L-shaped cross-sectional area lying against the edge strip of the insulating glazing and is then angled at an obtuse angle to form an outer cover flange.

Die innere Abdeckleiste weist beispielsweise eine h-förmige Querschnittsform auf, deren, bezogen auf den Buchstaben h, linker unterer Flansch in die Nut der Klemmleiste eingeschoben wird, deren rechter unterer Flansch die Klemmleiste von aussen abdeckt und deren oberer Flansch gegen den Randstreifen der lsolierverglasung anliegt.The inner cover strip has, for example, an H-shaped cross-sectional shape, the lower left flange of which is inserted into the groove of the terminal strip, the lower right flange covers the terminal strip from the outside and the upper flange lies against the edge strip of the insulating glazing .

Die erfindungsgemässen Profilleisten können aus Kunststoff bestehen, jedoch sind auch andere oder gleichzeitig mehrere verschiedene Materialien verwendbar. Beispielsweise ist eine Isolierverglasung bekannt, die bereits vom Hersteller mit einer umlaufenden, im Querschnitt U-förmigen Aluminium-Leiste umgeben wird, die einen zusätzlichen, einen Abschluss mit dem Flügelrahmen bildenden Flansch aufweist. Bei derartigen Aluminium-Rahmen besteht der Nachteil, dass das von der Rahmeninnenseite zur Rahmenaussenseite durchgehende Aluminium-Profil eine Kältebrücke darstellen kann. Voteilhaft ist dagegen, dass die Aluminium-Einfassung bereits beim Hersteller und damit kostengünstig hergestellt werden kann. Dieser Vorteil kann unter Ausschaltung der Bildung einer Kältebrücke beibehalten werden, wenn die erfindungsgemässe Klemmleiste zur Montage verwendet wird und die innere Abschlussleiste derart ausgebildet ist, dass sie den inneren Flansch des Aluminium-Profils übergreift.The profile strips according to the invention can be made of plastic, but other or several different materials can also be used. For example, insulating glazing is known, which is already surrounded by the manufacturer with an encircling aluminum strip which is U-shaped in cross section and which has an additional flange which forms an end with the casement frame. The disadvantage of aluminum frames of this type is that the aluminum profile which runs from the inside of the frame to the outside of the frame can constitute a cold bridge. On the other hand, it is advantageous that the aluminum edging can already be manufactured by the manufacturer and therefore inexpensively. This advantage can be maintained by eliminating the formation of a cold bridge if the terminal strip according to the invention is used for assembly and the inner end strip is designed such that it overlaps the inner flange of the aluminum profile.

Dieser innere Flansch des Aluminium-Profils kann auch bei vorgefertigten Aluminium-Einfassungen ganz entfallen, da eine Montage mit Hilfe der erfindungsgemässen Klemmleiste und Abschlussleiste ohne weiteres möglich ist.This inner flange of the aluminum profile can also be dispensed with entirely in the case of prefabricated aluminum surrounds, since assembly with the aid of the terminal strip and end strip according to the invention is readily possible.

Bei herkömmlichen Flügelrahmen befindet sich zumeist der Falz, wie bereits angedeutet wurde, auf der Gebäudeaussenseite, während die schräg abfallende Fläche des Flügelrahmens zur Gebäudeinnenseite hin geneigt ist. Auf diese Orientierung soll im Folgenden Bezug genommen werden, sofern die Aussen- oder Innenseite des Flügelrahmens angesprochen wird. Es liegt jedoch auf der Hand, dass auch eine umgekehrte Anordnung möglich ist.In conventional casements, as already indicated, the fold is usually on the outside of the building, while the sloping surface of the casement is inclined towards the inside of the building. This orientation should be referred to below, provided that the outside or inside of the casement is addressed. However, it is obvious that a reverse arrangement is also possible.

Im Folgenden werden bevorzugte Ausführungsbeispiele der Erfindung anhand der beigefügten Zeichnung näher erläutert.

  • Fig. 1 zeigt einen Schnitt durch einen erfindungsgemässen Einsatzrahmen mit Blend- und Flügelrahmen;
  • Fig. 2 ist ein entsprechender Schnitt, gesehen aus einer Position vom Gebäudeinneren her;
  • Fig. 3 veranschaulicht in einem Schnitt die Anwendung der Erfindung in Verbindung mit einem Aluminium-Profil.
Preferred exemplary embodiments of the invention are explained in more detail below with reference to the attached drawing.
  • Fig. 1 shows a section through an insert frame according to the invention with frame and sash;
  • Fig. 2 is a corresponding section, seen from a position from the inside of the building;
  • Fig. 3 illustrates in section the application of the invention in connection with an aluminum profile.

In Fig. 1 ist ein Blendrahmen mit 10 und ein Flügelrahmen mit 12 bezeichnet. Der Blendrahmen 10 trägt eine Dichtleiste 14 zur Abdichtung der Fuge zwischen Blendrahmen und Flügelrahmen, auf die hier nicht näher eingegangen werden soll. Der Querschnitt des Flügelrahmens lässt erkennen, dass dieser auf der links in Fig. 1 liegenden Gebäudeaussenseite einen Falz 16 aufweist, von dem aus die obere Oberfläche 18 des Flügelrahmens 12 schräg zum Gebäudeinneren hin abfällt. In dem Falz 16 befinden sich nicht näher bezeichnete Glas- und Kittreste. Eine Isolierverglasung 20 ist an den umlaufenden Rändern der die Isolierverglasung bildenden Glasscheibe durch eine geeignete, nicht näher bezeichnete Leiste in Verbindung mit Dicht- und Klebematerialien abgedichtet. Derartige Isolierverglasungen sind bekannt und sollen daher nicht näher erläutert werden.In Fig. 1, a frame 10 and a sash 12 is designated. The frame 10 carries a sealing strip 14 for sealing the joint between the frame and sash, which will not be discussed here. The cross-section of the casement shows that it has a fold 16 on the outside of the building on the left in FIG. 1, from which the upper surface 18 of the casement 12 slopes down towards the interior of the building. In the fold 16 there are unspecified glass and kit remains. An insulating glazing 20 is sealed on the circumferential edges of the glass pane forming the insulating glazing by means of a suitable strip (not specified in more detail) in connection with sealing and adhesive materials. Insulating glazing of this type is known and should therefore not be explained in more detail.

Der erfindungsgemässe Einsatzrahmen umfasst drei Profilleisten, die-bei rechteckigen Fensternauf Gehrung geschnitten und zu geschlossenen Rechtecken verbunden sind. Es handelt-sich dabei um eine Trägerleiste 22, eine Klemmleiste 24 und eine Abschlussleiste 26.The insert frame according to the invention comprises three profiled strips which are mitred in the case of rectangular windows and connected to form closed rectangles. It is a carrier strip 22, a terminal strip 24 and an end strip 26.

Die Trägerleiste 22 weist einen im Querschnitt im wesentlichen L-förmigen Profilbereich 28 auf, der mit einem ersten Flansch 30 die Isolierverglasung 20 auf dem Umfang umgibt und mit dem zweiten Flansch 32 gegen einen äusseren Randstreifen der Isolierverglasung unter Einfügung einer Gummidichtung 35, anliegt. Der erste Flansch 30 stützt sich auf dem oberen, an den Falz 16 angrenzenden Rücken des Flügelrahmens 12 ab. .Ausgehend vom oberen Rand des Flansches 32 weist die Trägerleiste 22 einen spitzwinklig abfallenden Flansch 34 und einen von dessen Rand ausgehenden, komplementär-stumpfwinklig abzweigenden Abdeckflansch 36 auf, der sich bis vor die Aussenfläche des Flügelrahmens 12 erstreckt und dort mit einem Steg 38 gegen den Flügelrahmen anliegt. An der Unterseite des Flansches 34 ist eine parallel zu den Flanschen 32, 36 verlaufende Verstärkungsrippe 40 ausgebildet.The carrier strip 22 has an essentially L-shaped profile area 28, which surrounds the insulating glazing 20 on the circumference with a first flange 30 and bears with the second flange 32 against an outer edge strip of the insulating glazing with the insertion of a rubber seal 35. The first flange 30 is supported on the upper back of the casement 12 adjoining the fold 16. Starting from the upper edge of the flange 32, the carrier strip 22 has a flange 34 which slopes at an acute angle and a cover flange 36 which branches off from its edge and branches off at a complementary obtuse angle, which extends to the outer surface of the casement 12 and there with a web 38 against the Sash frame rests. A reinforcing rib 40 running parallel to the flanges 32, 36 is formed on the underside of the flange 34.

Auf der Oberseite des in Fig. 1 und 2 gezeigten Flansches 30 befinden sich zwei längsgerichtete Rippen 42 unterhalb der Position der Glasscheiben der Isolierverglasung 20, so dass sie die Abstützung der Glasscheiben verbessern. An der Unterseite des Flansches 30 ist eine längsgerichtete Rippe 44 in der Nähe der freien Kante vorgesehen. In der Querschnittsform der Rippe 44 befinden sich auf der oberen Oberfläche der Klemmleiste 24 wenigstens zwei Nuten 46. Wenn die Trägerleiste 22 von links in Fig. 1, ggf. zusammen mit der Isolierverglasung 20 in den Flügelrahmen 12 eingeschoben worden ist, wird die Klemmleiste 24 unter Einfügung von Klebstoff keilförmig in den Zwischenraum zwischen der oberen und unteren Oberfläche 18 des Flügelrahmens 12 und dessen Schenkel 30 eingedrückt. Die Funktion der Nuten 46 und der Rippe 44 besteht darin, ein Einrasten zwischen den Profilleisten 1 und 2 in wenigstens zwei unterschiedlichen Positionen entsprechend der verwendeten Stärke der Isolierverglasung 20 zu gestatten. Nach diesem Einrasten liegen die Profilleisten 22, 24 bereits im Flügelrahmen 12 fest.On the top of the flange 30 shown in FIGS. 1 and 2 there are two longitudinal ribs 42 below the position of the glass panes of the insulating glazing 20, so that they improve the support of the glass panes. A longitudinal rib 44 is provided on the underside of the flange 30 near the free edge. In the cross-sectional shape of the rib 44, there are at least two grooves 46 on the upper surface of the terminal strip 24. If the carrier strip 22 has been pushed into the casement 12 from the left in FIG. 1, possibly together with the insulating glazing 20, the terminal strip 24 with the insertion of adhesive in a wedge shape into the space between the upper and lower surfaces 18 of the casement 12 and its legs 30. The function of the grooves 46 and the rib 44 is to allow a snap-in between the profile strips 1 and 2 in at least two different positions in accordance with the thickness of the insulating glazing 20 used. After this engagement, the profile strips 22, 24 are already fixed in the casement 12.

Die Abschlussleiste 26, die sich auf der Fensterinnenseite befindet, weist, wie bereits erwähnt wurde, im wesentlichen einen h-förmigen Querschnitt auf. Der, bezogen auf diesen Buchstaben, linke untere Flansch 48 dient zum Einschieben in eine Nut 50 auf der oberen Oberfläche der Klemmleiste 24 angrenzend an deren äusseren Rand, welche Nut 50 nach rechts in Fig. 1 durch einen leicht aufragenden, nicht näher bezeichneten Flansch abgeschlossen ist.The end strip 26, which is located on the inside of the window, has, as already mentioned, essentially an H-shaped cross section. The, based on this letter, the left lower flange 48 is used slide into a groove 50 on the upper surface of the terminal block 24 adjacent to its outer edge, which groove 50 is closed off to the right in FIG. 1 by a slightly protruding flange, not specified in more detail.

Der linke untere Flansch 48 geht nach oben in einen weiteren Flansch 52 über, der am oberen Ende stumpfwinklig zur Isolierverglasung 20 abgewinkelt ist und diese unter Einfügung von Dichtmaterialien abstützt und abdichtet. Der rechte untere Flansch 54 stützt sich auf der Oberfläche 18 des Flügelrahmens 12 ab.The lower left flange 48 merges upwards into a further flange 52, which is angled at an obtuse angle to the insulating glazing 20 and supports and seals it with the insertion of sealing materials. The lower right flange 54 is supported on the surface 18 of the casement 12.

Die im Querschnitt keilförmige Klemmleiste 24 verriegelt nicht nur die Trägerleiste 22 in dem Flügelrahmen 12, sondern trägt auch zur Abstützung der lsolierverglasung 20 bei.The clamping strip 24, which is wedge-shaped in cross section, not only locks the carrier strip 22 in the casement 12, but also contributes to supporting the insulating glazing 20.

Im Beispiel der Fig. 1 bestehen die drei Profilleisten 22, 24, 26 aus Kunststoff. Die Klemmleiste 24 und die Abstützleiste 26 können jedoch auch in Verbindung mit einer Trägerleiste aus Aluminium oder einer vorgefertigten Aluminium-Einrahmung verwendet werden, wie anschliessend erläutert werden soll.In the example of FIG. 1, the three profile strips 22, 24, 26 are made of plastic. The terminal strip 24 and the support strip 26 can, however, also be used in connection with a carrier strip made of aluminum or a prefabricated aluminum frame, as will be explained subsequently.

Die letztgezeigte Anwendung der Erfindung ist in Fig. 3 dargestellt. Eine insgesamt mit 56 bezeichnete Profilleiste besteht aus Aluminium und erfasst die Isolierverglasung 20 mit einem im Querschnitt U-förmigen Querschnittsbereich 58. Von diesem geht nach links unten in Fig. 3 ein Flansch 60 aus, der den Flügelrahmen 12 von der links in Fig. 3 liegenden Aussenseite her übergreift und abdeckt. An der Unterseite der Profilleiste 56 in der Nähe von deren rechtem Rand in Fig. 3 befindet sich wiederum eine Rippe 62, die der Rippe 44 in der Fig. 1 entspricht. Mit der Rippe 62 wirken wiederum die Nuten 46 der Klemmleiste 24 zusammen, die in Fig. 1 näher dargestellt sind. Die Abschlussleiste 26 ist derart ausgebildet, dass ihr senkrecht aufragender Flansch 52 mit dessen stumpfwinklig nach innen abgewinkelten Endbereich den inneren, senkrechten Flansch der Aluminium-Profilleiste 56 abdeckt und von oben übergreift, so dass dieser nach innen nicht sichtbar ist und nicht als Kältebrücke dienen kann.The last shown application of the invention is shown in FIG. 3. A profile strip, designated overall by 56, is made of aluminum and grasps the insulating glazing 20 with a cross-sectional area 58 which is U-shaped in cross section. A flange 60 extends from this to the bottom left in FIG. 3, which flaps the sash frame 12 from the left in FIG. 3 overlaps and covers. On the underside of the profile strip 56 in the vicinity of its right edge in FIG. 3 there is again a rib 62 which corresponds to the rib 44 in FIG. 1. The grooves 46 of the terminal block 24, which are shown in more detail in FIG. 1, interact with the rib 62. The end strip 26 is designed in such a way that its vertically projecting flange 52, with its end region angled inward at an obtuse angle, covers the inner, vertical flange of the aluminum profile strip 56 and overlaps it from above, so that it is not visible from the inside and cannot serve as a cold bridge .

In Abweichung von Fig. 3 kann der rechts in Fig. 3 liegende, senkrechte Flansch der Aluminium-Profilleiste 56, der mit 64 bezeichnet ist, fortgelassen werden. In diesem Falle entspricht das Aluminium-Profil im wesentlichen dem Kunststoff-Profil der Trägerleiste 22 gemäss Fig. 1. Es kann auch insoweit in gleicher Weise eingesetzt werden, als es möglich ist, die Isolierverglasung 20 in die abgeänderte Aluminium-Profilleiste 56 einzuschieben, nachdem diese im Flügelrahmen montiert und die Klemmleiste 24 eingeschoben ist.3, the vertical flange of the aluminum profile strip 56, which is located on the right in FIG. 3 and is denoted by 64, can be omitted. In this case, the aluminum profile corresponds essentially to the plastic profile of the carrier strip 22 according to FIG. 1. It can also be used in the same way as it is possible to insert the insulating glazing 20 into the modified aluminum profile strip 56 after this is mounted in the casement and the terminal block 24 is inserted.
