Description

Die vorliegende Erfindung betrifft einen zu einem Blendrahmen eines Fensters oder einer Tür relativ beweglichen Flügel gemäß dem Oberbegriff des Anspruchs 1 sowie ein Verfahren zur Fixierung zweier im Bereich einer Gehrung aneinander liegender Hauptprofile.The present invention relates to a sash movable relative to a frame of a window or door according to the preamble of claim 1 and to a method for fixing two main profiles lying against each other in the area of a miter joint.

Gattungsgemäße Flügel für Fenster oder Türen sind beispielsweise aus der AT 413 850 B bekannt. Zur Unterstützung der Maßhaltigkeit des Fügeprozesses und zur Abtragung der Glaslast einer Glasscheibe werden in die Flügel Stützwinkel eingeschoben, die vom horizontalen und vertikalen Rahmenprofil des Flügels gestützt wird.Standard sashes for windows or doors are, for example, made from the AT 413 850 B known. To support the dimensional accuracy of the joining process and to transfer the glass load of a glass pane, support brackets are inserted into the sash, which are supported by the horizontal and vertical frame profile of the sash.

Problematisch bei diesen Eckträgern ist die bislang nur unzureichende Abstützung des Flügels. Weiterer Nachteil ist die relativ aufwändige Montage.A problem with these corner brackets is the currently inadequate support they provide for the sash. Another disadvantage is the relatively complex installation.

Zur verbesserten Abstützung ist es aus der US 2022/090439 A1 bekannt, Eckträger über in Schraubkanäle benachbarter Hauptprofile eingeschraubte Schrauben an den aneinander liegenden Hauptprofilen festzulegen.For improved support, it is made from the US 2022/090439 A1 It is known to fix corner supports to adjacent main profiles by means of screws screwed into screw channels of adjacent main profiles.

Aufgabe der vorliegenden Erfindung ist es, einen zu einem Blendrahmen eines Fensters oder einer Tür relativ beweglichen Flügel bereitzustellen, der in einfacher Weise montierbar ist und in dem wenigstens ein Eckträger eingebaut ist, der eine weiter verbesserte Abstützung des Flügels gewährleistet.The object of the present invention is to provide a sash that is relatively movable relative to a frame of a window or door, which can be easily mounted and in which at least one corner support is installed, which ensures further improved support of the sash.

Die gestellte Aufgabe wird durch einen zu einem Blendrahmen eines Fensters oder einer Tür relativ beweglichen Flügel mit den Merkmalen des Anspruchs 1 sowie durch ein Verfahren zur Fixierung zweier im Bereich einer Gehrung aneinander liegender Hauptprofile mit den Merkmalen des Anspruchs 14 gelöst.The problem is solved by a sash movable relative to a frame of a window or door with the features of claim 1 and by a method for fixing two main profiles lying next to each other in the area of a miter with the features of claim 14.

Der erfindungsgemäße Flügel weist einen Flügelrahmen aus in Ecken miteinander verbundenen Flügelrahmenprofilen auf. An dem Flügelrahmen ist ein Flächenelement, beispielsweise in Gestalt einer Glasscheibe, befestigt.The wing according to the invention has a wing frame made of wing frame profiles connected to each other at the corners. A surface element, for example in the form of a glass pane, is attached to the wing frame.

Jedes Flügelrahmenprofil weist ein Hauptprofil und ein daran festgelegtes oder ausgebildetes Isolierprofil auf.Each sash frame profile has a main profile and an insulating profile attached to or formed on it.

In einer oder mehreren, insbesondere sämtlichen der Ecken des Flügelrahmens ist jeweils ein Eckträger angeordnet, der zwei sich winklig, insbesondere rechtwinklig, zueinander erstreckende Schenkel aufweist, die in einem Eckbereich miteinander verbunden sind und von denen einer oder beide Schenkel einen Befestigungsabschnitt zum Festlegen an einem jeweiligen der in den Ecken aneinanderstoßenden Hauptprofile aufweist/aufweisen.In one or more, in particular all, of the corners of the wing frame, a corner support is arranged which has two legs extending at an angle, in particular at right angles, to each other, which are connected to each other in a corner area and of which one or both legs have a fastening section for fixing to one of the respective main profiles that meet in the corners.

An den Hauptprofilen ist jeweils wenigstens ein sich über die Länge des jeweiligen Flügelrahmenprofils erstreckender nutförmiger erster Schraubkanal angeformt.Each of the main profiles has at least one groove-shaped first screw channel formed over the length of the respective wing frame profile.

Die Eckträger sind über in die ersten Schraubkanäle eingeschraubte erste Schrauben an den aneinander liegenden Hauptprofilen festgelegt.The corner supports are fixed to the adjacent main profiles by means of first screws screwed into the first screw channels.

Die beiden Schenkel des Eckträgers weisen einen Abstützabschnitt zur Auflage auf einem jeweiligen der in den Ecken aneinanderstoßenden Hauptprofile der Flügelrahmenprofile auf.The two legs of the corner support have a support section for resting on one of the respective main profiles of the wing frame profiles that meet at the corners.

Nahe des Abstützabschnitts ist ein Stützsteg angeformt, der im montierten Zustand in einer Nut des Hauptprofils aufgenommen ist.Near the support section, a support web is molded in, which, in the assembled state, is received in a groove of the main profile.

Durch die Vorsehung der ersten Schraubkanäle ist es auf der bevorzugt gesamten Profillänge ermöglicht, Komponenten und Beschlagteile in einfacher Weise ohne spanende Bearbeitung zu befestigen. Die jeweiligen Komponenten können so über den ersten Schraubkanal am Profil exakt ausgerichtet und positioniert werden.The provision of the first screw channels allows components and fittings to be easily attached along the entire length of the profile without machining. The individual components can thus be precisely aligned and positioned on the profile via the first screw channel.

Durch den Stützsteg ist eine zuverlässige Abtragung insbesondere von Windlasten, die auf das Flächenelement wirken, in das Hauptprofil ermöglicht, ohne das Isolierprofil zu stark zu belasten.The supporting rib enables reliable transfer of wind loads, in particular those acting on the surface element, into the main profile without placing excessive stress on the insulating profile.

Vorteilhafte Ausführungsvarianten der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.

An den Hauptprofilen sind wenigstens zwei über die Länge des jeweiligen Flügelrahmenprofils sich erstreckende nutförmige Schraubkanäle angeformt. Ein erster der Schraubkanäle ist zu einer dem Eckträger zugewandten Innenseite des jeweiligen Flügelrahmenprofils offen und ein zweiter Schraubkanal zu einer dem Eckträger abgewandten Außenseite des jeweiligen Flügelrahmenprofils.The main profiles have at least two groove-shaped screw channels extending along the length of the respective sash frame profile. A first screw channel opens to an inner side of the respective sash frame profile facing the corner member, and a second screw channel opens to an outer side of the respective sash frame profile facing away from the corner member.

Die in Ecken miteinander verbundenen Flügelrahmenprofile sind durch in die zweiten Schraubkanäle der aneinander liegenden Hauptprofile eingeschraubte zweite Schrauben miteinander verbunden, wobei ein einem Schraubenkopf naher Bereich der ersten Schrauben orthogonal zur Längserstreckung des Schraubkanals eines ersten der Flügelrahmenprofile und ein dem Schraubenkopf ferner Bereich der zweiten Schrauben in Richtung der Längserstreckung eines zweiten der Flügelrahmenprofile aufgenommen ist.The sash frame profiles connected at corners are connected to each other by second screws screwed into the second screw channels of the adjacent main profiles, wherein a region of the first screws close to a screw head is orthogonal to the longitudinal extent of the screw channel of a first of the sash frame profiles and a region of the second screws farther from the screw head is received in the direction of the longitudinal extent of a second of the sash frame profiles.

Mit einem solchermaßen ausgebildeten Flügel ist in einfacher Weise eine direkte Verschraubung der Flügelrahmenprofile ohne spanende Bearbeitung ermöglicht.With a wing designed in this way, direct screwing of the wing frame profiles without machining is easily possible.

Gemäß einer bevorzugten Weiterbildung ist zumindest eine der in den ersten Schraubkanal eines der Hauptprofile eingeschraubten ersten Schrauben stumpfwinklig in den ersten Schraubkanal eingeschraubt, wobei der stumpfe Winkel von einem nicht von dem Eckträger bedeckten Bereich des Hauptprofils her gemessen ist.According to a preferred embodiment, at least one of the first screws screwed into the first screw channel of one of the main profiles is screwed into the first screw channel at an obtuse angle, the obtuse angle being measured from an area of the main profile not covered by the corner support.

Durch das stumpfwinklige Einschrauben insbesondere der Eckprofile ist es ermöglicht, die Lastabtragung über die Eckprofile auf das Hauptprofil zu übertragen.By screwing in the corner profiles at an obtuse angle, it is possible to transfer the load via the corner profiles to the main profile.

Gemäß einer weiteren Ausführungsvariante weisen die Eckträger Schraubenaufnahmen zur Vorpositionierung der ersten Schrauben auf.According to another design variant, the corner supports have screw receptacles for pre-positioning the first screws.

Nach einer bevorzugten Weiterbildung weisen wenigstens eine der Schraubenaufnahmen zur Vorpositionierung der stumpfwinklig in den ersten Schraubkanal einzuschraubenden ersten Schraube einen stumpfwinklig zur Längserstreckung des Schenkels des Eckträger in den Schenkel eingelassenen Führungsabschnitt auf.According to a preferred further development, at least one of the screw receptacles for pre-positioning the first screw, which is to be screwed into the first screw channel at an obtuse angle, has a guide section recessed into the leg at an obtuse angle to the longitudinal extension of the leg of the corner support.

Dadurch ist das stumpfwinklige Einschrauben der ersten Schrauben in den ersten Schraubkanal nochmals erleichtert.This makes it even easier to screw the first screws into the first screw channel at an obtuse angle.

Die Schraubkanäle sind gemäß einer bevorzugten Ausführungsvariante im Querschnitt etwa u-förmig geformt.According to a preferred embodiment, the screw channels are shaped approximately in a U-shape in cross-section.

Nach einer weiteren vorteilhaften Ausführungsvariante ist in dem ersten Schraubkanal wenigstens ein dünnwandiger Fixiersteg ausgebildet, in den der Schraubenhals der ersten Schraube schneidend einschraubbar ist.According to a further advantageous embodiment, at least one thin-walled fixing rib is formed in the first screw channel, into which the screw neck of the first screw can be screwed in a cutting manner.

Der dünnwandige Fixiersteg dient dabei zum einen der Dichtigkeit des Hauptprofils und zum zweiten der verbesserten Fixierung der jeweiligen Komponente.The thin-walled fixing rib serves two purposes: firstly, to ensure the tightness of the main profile, and secondly, to improve the fixing of the respective component.

Nach einer weiteren vorteilhaften Ausführungsvariante ist bzw. sind wenigstens einer der Schraubkanäle, insbesondere alle Schraubkanäle mit einer sich in Längserstreckung der Schraubkanäle erstreckenden Verzahnung ausgebildet.

In der nachfolgenden Figurenbeschreibung beziehen sich Begriffe wie oben, unten, links, rechts, vorne, hinten usw. ausschließlich auf die in den jeweiligen Figuren gewählte beispielhafte Darstellung und Position der Flügel, Hauptprofil, Isolierprofil, Außenprofil, Eckträger und dergleichen. Diese Begriffe sind nicht einschränkend zu verstehen, d.h., durch verschiedene Arbeitsstellungen oder die spiegelsymmetrische Auslegung oder dergleichen können sich diese Bezüge ändern.In the following figure descriptions, terms such as top, bottom, left, right, front, back, etc., refer exclusively to the exemplary representation and position of the wings, main profile, insulating profile, outer profile, corner members, and the like as chosen in the respective figures. These terms are not to be understood as restrictive; that is, these relationships may change due to different working positions, mirror-symmetrical design, or similar factors.

In der Figur 1 ist mit dem Bezugszeichen 3 insgesamt eine Ausführungsvariante eines erfindungsgemäßen Flügels eines Fensters oder einer Tür bezeichnet, der zu einem Blendrahmen des Fensters oder der Tür relativ beweglich ist. In der nachfolgenden Beschreibung wird der Flügel 3 im zumindest überwiegenden Maße als Flügel eines Fensters beschrieben, der Begriff "Fenster" kann jedoch synonym durch den Begriff "Tür" ersetzt werden.In the Figure 1 Reference numeral 3 designates a variant embodiment of a window or door sash according to the invention, which is movable relative to a frame of the window or door. In the following description, sash 3 is described primarily as a window sash; however, the term "window" can be used synonymously with "door".

Der in Figur 1 abgebildete Flügel 3 ist zum Einsetzen in eine in eine Öffnung einer Wand eines Gebäudes eingebauten Blendrahmen ausgelegt. Der Flügel 3 ist dabei relativ zum Blendrahmen (nicht dargestellt) beweglich, insbesondere um eine vertikale Drehachse drehbar und/oder um eine horizontale Achse x schwenkbar.The in Figure 1 The illustrated sash 3 is designed for insertion into a frame installed in an opening in the wall of a building. The sash 3 is movable relative to the frame (not shown), in particular rotatable about a vertical axis of rotation and/or pivotable about a horizontal axis x.

Der Flügel 3 weist einen Flügelrahmen aus in Ecken 33 miteinander verbundenen Flügelrahmenprofilen 31, 32 auf. An dem Flügelrahmen ist ein hier nicht dargestelltes Flächenelement befestigt, insbesondere in Gestalt einer Glasscheibe.The sash 3 has a sash frame made of sash frame profiles 31, 32 connected to each other at corners 33. A surface element, not shown here, is attached to the sash frame, in particular in the form of a glass pane.

Wie weiter in den Figuren 1 bis 3 und 5 dargestellt ist, weist jedes der Flügelrahmenprofile 31, 32 ein Hauptprofil 4 und ein daran befestigtes oder auch angeformtes Isolierprofil 5 auf.What next in the Figures 1 to 3 and 5 As shown, each of the wing frame profiles 31, 32 has a main profile 4 and an insulating profile 5 attached to it or molded onto it.

Bevorzugt ist das Isolierprofil 5 an seiner dem Hauptprofil 4 abgewandten Seite mit einem Außenprofil 6 verbunden. Das Hauptprofil 4 ist dabei im geschlossenen Zustand des Fensters dem Gebäudeinneren zugewandt, während das Außenprofil 6 der Umgebung außerhalb des Gebäudes zugewandt ist.Preferably, the insulating profile 5 is connected to an outer profile 6 on its side facing away from the main profile 4. When the window is closed, the main profile 4 faces the interior of the building, while the outer profile 6 faces the environment outside the building.

In einer oder mehreren, insbesondere sämtlichen der Ecken 33 des Flügelrahmens ist zur Abstützung des Flächenelements jeweils ein Eckträger 7 angeordnet, der zwei sich winklig, insbesondere rechtwinklig, zueinander erstreckende Schenkel 71, 72 aufweist. Diese Schenkel 71, 72 sind in einem Eckbereich 75 miteinander verbunden.In one or more, in particular all, of the corners 33 of the sash frame, a corner support 7 is arranged to support the surface element, the corner support having two legs 71, 72 extending at an angle, in particular at right angles, to each other. These legs 71, 72 are connected to each other in a corner area 75.

Der/die Eckträger 7 ist/sind bevorzugt einstückig ausgebildet.The corner support 7 is/are preferably made in one piece.

Wie insbesondere in Figur 5 dargestellt ist, weist einer oder beide Schenkel 71, 72 einen Befestigungsabschnitt 74 zum Festlegen an einem jeweiligen der jeweiligen in den Ecken aneinander stoßenden Hauptprofile 4 auf.As particularly in Figure 5 As shown, one or both legs 71, 72 have a fastening section 74 for fixing to one of the respective main profiles 4 that meet at the corners.

Beide Schenkel 71, 72 weisen einen Abstützabschnitt 77 zur Auflage auf einem jeweiligen der in den Ecken 33 aneinander stoßenden Hauptprofile 4 der Flügelrahmenprofile 31, 32 auf.Both legs 71, 72 have a support section 77 for resting on one of the respective main profiles 4 of the wing frame profiles 31, 32 which meet at the corners 33.

An den Hauptprofilen 4 ist jeweils wenigstens ein sich über die Länge des jeweiligen Flügelrahmenprofils erstreckender nutförmiger erster Schraubkanal 43 angeformt.Each of the main profiles 4 has at least one groove-shaped first screw channel 43 formed over the length of the respective wing frame profile.

Wie insbesondere in den Figuren 2 und 3 dargestellt ist, sind an den Hauptprofilen 4 zwei über die Länge des jeweiligen Flügelrahmenprofils 31, 32 sich erstreckende nutförmige Schraubkanäle 42, 43 angeformt.As especially in the Figures 2 and 3 As shown, two groove-shaped screw channels 42, 43 extending over the length of the respective wing frame profile 31, 32 are formed on the main profiles 4.

Ein ersten Schraubkanal 43 ist zu einer dem Eckträger 7 zugewandten Innenseite des jeweiligen Flügelrahmenprofils 31, 32 offen.A first screw channel 43 is open to an inside side of the respective wing frame profile 31, 32 facing the corner support 7.

Ein zweiter Schraubkanal 42 ist zu einer dem Eckträger 7 abgewandten Außenseite des jeweiligen Flügelrahmenprofils 31, 32 offen.A second screw channel 42 is open to an outer side of the respective wing frame profile 31, 32 facing away from the corner support 7.

Die Eckträger 7 sind dabei über in die ersten Schraubkanäle 43 eingeschraubte erste Schrauben 8 an den aneinander liegenden Hauptprofilen 4 festgelegt.The corner supports 7 are fixed to the adjacent main profiles 4 by means of first screws 8 screwed into the first screw channels 43.

Die in den Ecken 33 miteinander verbundenen Flügelrahmenprofile 31, 32 sind durch in die zweiten Schraubkanäle 42 der aneinander liegenden Hauptprofile 4 eingeschraubte zweite Schrauben 9 miteinander verbunden, wie es aus der Figur 4 ersichtlich ist.The sash frame profiles 31, 32, which are connected to each other at the corners 33, are connected to each other by second screws 9 screwed into the second screw channels 42 of the adjacent main profiles 4, as can be seen from the Figure 4 as is evident.

Wie weiter in Figur 4 dargestellt ist, ist ein einem Schraubenkopf 91 naher Bereich der zweiten Schrauben 9 orthogonal zur Längserstreckung des zweiten Schraubkanals 42 eines ersten der Flügelrahmenprofile 31, 32 in den zweiten Schraubkanal 42 eingeschraubt. Ein dem Schraubenkopf 91 ferner Bereich der zweiten Schrauben 9 ist in Richtung der Längserstreckung des am ersten der Flügelrahmenprofile 31, 32 anliegenden zweiten der Flügelrahmenprofile 31, 32 in dessen zweiten Schraubkanal 42 eingeschraubt.What's next in Figure 4 As shown, a region of the second screws 9 close to a screw head 91 is screwed into the second screw channel 42 orthogonally to the longitudinal extent of the second screw channel 42 of a first of the sash frame profiles 31, 32. A region of the second screws 9 farther from the screw head 91 is screwed into the second screw channel 42 of the second of the sash frame profiles 31, 32, which abuts the first of the sash frame profiles 31, 32, in the direction of its longitudinal extent.

Die ersten nutförmige Schraubkanäle 42 ermöglichen so ohne zusätzliche Fräsarbeiten eine zuverlässige Verbindung der jeweiligen Flügelrahmenprofile 31, 32 im Bereich der aneinander stoßenden, bevorzugt auf Gehrung geschnittenen Enden 33 der jeweiligen Flügelrahmenprofile 31, 32.The first groove-shaped screw channels 42 thus enable a reliable connection of the respective sash frame profiles 31, 32 in the area of the abutting, preferably mitered, ends 33 of the respective sash frame profiles 31, 32 without additional milling work.

Die ersten Schraubkanäle 43 dienen der Anbringung weiterer Funktionsbauteile an den Flügelrahmenprofilen 31, 32.The first screw channels 43 serve to attach further functional components to the wing frame profiles 31, 32.

So sind insbesondere die Eckträger 7 über in die ersten Schraubkanäle 43 eingeschraubten ersten Schrauben 8 an den aneinander liegenden Hauptprofilen 4 festgelegt, wie es beispielhaft in Figur 1 dargestellt ist.In particular, the corner supports 7 are fixed to the adjacent main profiles 4 by means of the first screws 8 screwed into the first screw channels 43, as is shown for example in Figure 1 is shown.

Wie weiter den Figuren 5 - 8 zu entnehmen ist, ist zumindest eine der in den ersten Schraubkanal 43 eines der Hauptprofile 4 eingeschraubten ersten Schrauben 8 stumpfwinklig in den ersten Schraubkanal 43 eingeschraubt.What next? Figures 5 - 8 As can be seen, at least one of the first screws 8 screwed into the first screw channel 43 of one of the main profiles 4 is screwed into the first screw channel 43 at an obtuse angle.

Dieser stumpfe Winkel α ist dabei von einem nicht von dem Eckträger bedeckten Bereich des Hauptprofils 4 aus gemessen, wie es aus Figur 8 ersichtlich ist. Der stumpfe Winkel α beträgt dabei vorzugsweise zwischen 91 und 115°, besonders bevorzugt zwischen 95 und 115°.This obtuse angle α is measured from an area of the main profile 4 not covered by the corner support, as shown from Figure 8 This is evident. The obtuse angle α is preferably between 91 and 115°, particularly preferably between 95 and 115°.

Der in Figur 8 gezeigte weitere Winkel β stellt einen rechten Winkel dar.The in Figure 8 The other angle shown, β, represents a right angle.

Die Eckträger 7 weisen, wie in den Figuren 5, 6 und 8 gut zu erkennen ist, bevorzugt Schraubenaufnahmen 76 zur Vorpositionierung der ersten Schrauben 8 auf.The corner beams 7 show, as in the Figures 5 , 6 and 8 As can be clearly seen, screw receptacles 76 are preferred for pre-positioning the first screws 8.

Dabei ist bevorzugt wenigstens eine der Schraubenaufnahmen 76 zur Vorpositionierung der stumpfwinklig in den ersten Schraubkanal 43 einzuschraubenden ersten Schraube 8 mit einem stumpfwinklig zur Längserstreckung des Schenkels 71, 72 des Eckträgers 7 in den Schenkel 71 eingelassenen Führungsabschnitt 78 ausgebildet.Preferably, at least one of the screw receptacles 76 for pre-positioning the first screw 8 to be screwed into the first screw channel 43 at an obtuse angle is designed with a guide section 78 recessed into the leg 71 at an obtuse angle to the longitudinal extension of the leg 71, 72 of the corner support 7.

Die Schraubkanäle 42, 43 sind im Querschnitt bevorzugt etwa u-förmig ausgebildet.The screw channels 42, 43 are preferably formed in cross-section in an approximately U-shape.

Die Seitenwände dieser Schraubkanäle 42, 43 sind bevorzugt mit einer sich in Längserstreckung der Schraubkanäle 42, 43 erstreckenden Verzahnung 46 ausgebildet.The side walls of these screw channels 42, 43 are preferably formed with a toothing 46 extending in the longitudinal extent of the screw channels 42, 43.

Zur weiter verbesserten Fixierung ist die Verzahnung 46 an den Seitenwänden der Schraubkanäle 42, 43 senkrecht zur Längserstreckung des jeweiligen Schraubkanals 42, 43 betrachtet versetzt zueinander ausgebildet.For further improved fixation, the toothing 46 on the side walls of the screw channels 42, 43 is offset from each other when viewed perpendicular to the longitudinal extent of the respective screw channel 42, 43.

Weiter sind zur verbesserten Halterung sowie Abdichtung in dem ersten Schraubkanal 43 wenigstens ein dünnwandiger Fixiersteg 44 ausgebildet, in den der Schraubenhals 82 der ersten Schraube 8 schneidend einschraubbar ist.Furthermore, for improved retention and sealing, at least one thin-walled fixing rib 44 is formed in the first screw channel 43, into which the screw neck 82 of the first screw 8 can be screwed in a cutting manner.

Wie weiter in Figur 6 veranschaulicht ist, ist der Abstützabschnitt 77 des Eckträgers 7 an seinem dem Befestigungsabschnitt 74 entfernten Ende von dem Isolierprofil 5 weg, das Flächenelement umgreifend, umgekantet ausgebildet.What's next in Figure 6 As illustrated, the support section 77 of the corner beam 7 is formed at its end furthest from the fastening section 74, away from the insulating profile 5, encompassing the surface element, and folded over.

Die Umkantung 73 sorgt so dafür, dass eine beispielsweise durch Windsog erzeugte Drucklast über die Umkantung 73 in den Abstützabschnitt 77 des Eckträgers 7 eingeleitet wird, der über den Befestigungsabschnitt 74 mit dem Hauptprofil verbunden ist, so dass die Drucklast in das Hauptprofil eingeleitet wird.The folded edge 73 ensures that a pressure load generated, for example, by wind suction, is introduced via the folded edge 73 into the support section 77 of the corner beam 7, which is connected to the main profile via the fastening section 74, so that the pressure load is introduced into the main profile.

Der Befestigungsabschnitt 74 des Eckträgers 7 weist eine in eine Nut 48 vorstehenden Stützsteg 79 auf. Seitlich unterhalb des Stützsteges 79 liegt der Abstützabschnitt 77 des Eckträgers 7 auf einer lastaufnehmenden Andruckfläche 47 des Hauptprofils 4 auf und ermöglicht so in Zusammenwirken mit einem die Nut 48 begrenzenden Kontersteg 49 eine Abtragung der Last des auf den Eckträger 7 wirkenden Flächenelements, beispielsweise in Gestalt einer Glasscheibe, in das Hauptprofil 4.The fastening section 74 of the corner beam 7 has a support web 79 projecting into a groove 48. Laterally below the support web 79, the support section 77 of the corner beam 7 rests on a load-bearing pressure surface. 47 of the main profile 4 and thus, in conjunction with a counter web 49 limiting the groove 48, enables the load of the surface element acting on the corner beam 7, for example in the form of a glass pane, to be transferred into the main profile 4.

Zumindest eine Teilmenge der Schrauben 8, 9 sind bevorzugt als Justierschrauben mit sich abschnittsweise verändernder Gewindesteigung ausgebildet, was dazu führt, dass die Flügelrahmenecken beim Verschrauben weiter zusammengepresst werden. Hier ist die Gewindesteigung nahe am Schraubenkopf geringer als die Gewindesteigung nahe dem dem Schraubenkopf abgewandten Ende der Schraube 8, 9.At least a subset of the screws 8, 9 are preferably designed as adjusting screws with a thread pitch that changes section by section, which results in the sash frame corners being pressed together further when screwed in. Here, the thread pitch near the screw head is lower than the thread pitch near the end of the screw 8, 9 furthest from the screw head.

Wie weiter in den Figuren 6 und 11 bis 13 gezeigt ist, ist das Isolierprofil 5 auf der einen Seite mit dem Hauptprofil 4 und auf der anderen Seite mit dem Außenprofil 6 durch eine Steck- und/oder Rastverbindung miteinander gekoppelt. Wie insbesondere in Figur 12 gezeigt ist, ist dazu seitlich des ersten Schraubkanals 43 ein Raststeg 45 angeformt, der beim Aufstecken des Isolierprofils 5 in eine entsprechend geformte Rastnut 52 eingesteckt wird und so das Isolierprofil 5 zuverlässig am Hauptprofil 4 hält.What next in the Figure 6 and 11 to 13 As shown, the insulating profile 5 is coupled to the main profile 4 on one side and to the outer profile 6 on the other side by a plug-in and/or snap-fit connection. As shown in particular in Figure 12 As shown, a locking tab 45 is formed on the side of the first screw channel 43, which is inserted into a correspondingly shaped locking groove 52 when the insulating profile 5 is attached, thus reliably holding the insulating profile 5 on the main profile 4.

Eine gleichermaßen ausgeführte oder ähnliche Verbindung besteht zwischen dem Isolierprofil 5 und dem Außenprofil 6. Hier stehen vom Isolierprofil 5 in Richtung des Außenprofils 6 Raststege 53a, 53b ab, die von Raststegen 62a, 62b des Außenprofils 6 umgriffen werden.A connection of the same or similar design exists between the insulating profile 5 and the outer profile 6. Here, locking webs 53a, 53b extend from the insulating profile 5 towards the outer profile 6 and are engaged by locking webs 62a, 62b of the outer profile 6.

Figur 13 zeigt eine alternative Ausführungsvariante, die nicht Teil der vorliegenden Erfindung ist, zur Verbindung zweier Profile 110 über jeweilige Verbindungsstücke 120. Figure 13 Figure 1 shows an alternative embodiment , which is not part of the present invention, for connecting two profiles 110 via respective connecting pieces 120.

Die Profile 110 sind hier der Übersichtlichkeit halber stark vereinfacht als Block dargestellt, bei dem jeweils nur Rollleisten 111 und Konterleisten 112 sowie eine gegebenenfalls vorhandene Riffelung 113 dargestellt sind.For the sake of clarity, the profiles 110 are shown here in a highly simplified form as a block, in which only roller strips 111 and counter strips 112 and any existing ribbing 113 are shown.

Auch an den Verbindungsstücken 120 sind außenseitig Verbindungsnasen 121 dargestellt, die zur Verbindung mit den Profilen 110 zwischen die Rollleiste 111 und die Konterleiste 112 eingeschoben werden und anschließend durch Überrollen der Rollleiste 111 mit einem Rollwerkzeug in einfacher Weise fixiert werden können.Connecting lugs 121 are also shown on the outside of the connecting pieces 120, which are inserted between the roller strip 111 and the counter strip 112 for connection with the profiles 110 and can then be easily fixed by rolling over the roller strip 111 with a rolling tool.

Das erfindungsgemäße Verfahren zur Fixierung zweier im Bereich einer Gehrung aneinander liegender Hauptprofile 4 eines Flügels 3 weist die folgenden Verfahrensschritte auf:
Zunächst werden zwei der Hauptprofile 4 im Bereich einer jeweiligen Gehrungskante aneinandergelegt. Sodann wird ein Eckträger 7 auf einen Inneneckbereich der zusammengesetzten Hauptprofile 4 aufgesetzt und durch Einschrauben der ersten Schrauben 8 in den jeweiligen ersten Schraubkanal 43 mit den aneinander liegenden Hauptprofilen 4 verschraubt.The inventive method for fixing two main profiles 4 of a wing 3 lying next to each other in the area of a miter joint comprises the following method steps:
First, two of the main profiles 4 are placed next to each other in the area of their respective mitered edges. Then, a corner bracket 7 is placed on an inside corner area of the assembled main profiles 4 and screwed to the adjacent main profiles 4 by screwing the first screws 8 into the respective first screw channel 43.

Zumindest einige der Schrauben 8, bevorzugt die von der Ecke aus betrachtet äußeren der ersten Schrauben 8 werden dabei stumpfwinklig in einem Winkel (α) in den ersten Schraubkanal 43 des jeweiligen Hauptprofils 4 eingeschraubt.At least some of the screws 8, preferably the outermost of the first screws 8 viewed from the corner, are screwed into the first screw channel 43 of the respective main profile 4 at an obtuse angle (α).

Durch Anziehen der ersten Schrauben 8 in den ersten Schraubkanälen 43 erfolgt ein Zusammenpressen der Hauptprofile 4 in eine vorbestimmte Winkelstellung.By tightening the first screws 8 in the first screw channels 43, the main profiles 4 are pressed together into a predetermined angular position.
