Abstract

The insulating connection consists of an insulating strip fitting positively to the aluminum strips. In cross section, the insulating strip (20) has a middle sector with a bulge and webs (21) on both side connecting with the strip halves (11, 16). There are nose sectors on both sides of the bulge extending these webs, on which reinforcing strips (25) are fitted.

Description

Die Erfindung betrifft einen Isolierverbund für Aluminiumprofile. insbesondere für Fenster. Türen o.dgl., mit einer äußeren und einer inneren Profilhälfte, die mit einem beidseits mit den Profilhälften formschlüssig verbundenen Isolierprofil zusammengefügt sind; sie betrifft ferner einen Rahmen für eine Tür, ein Fenster o.dgl. aus im wesentlichen U-förmig zusammengefügten Aluminiumprofilen. deren äußere und innere Profilhälften mit einem Isolierverbund verbunden sind.The invention relates to an insulating composite for aluminum profiles. especially for windows. Doors or the like, with an outer and an inner Profile half, with a form-fitting on both sides with the profile halves connected insulating profile are joined together; she concerns Further, a frame for a door, a window or the like. essentially U-shaped assembled aluminum profiles. their outer and inner Profile halves are connected to an insulating composite.

Um Fenster oder Türen mit Metall- insbesondere mit Aluminium-Rahmen herzustellen, die hinreichende Wärmeisolation aufweist, ist bekannt. an einen ersten Rahmen einen zweiten Rahmen anzusetzen. wobei beide mit entsprechenden Füllungen versehen sind, und wobei beide als Isolierverbund durch Distanzklötzchen auf Abstand gehalten sind. Dabei bildet die Luftschicht zwischen beiden Rahmen in Verbindung mit dem wegen des Materials und des Querschnittes der Distanzklötzchen die den Wärmedurchfluss begrenzende Wärmeisolation. Bei dieser Konstruktion sind die beiden Rahmen im wesentlichen unabhängig voneinander, so dass der Isolierverbund keine Schubspannungen aufzunehmen in der Lage ist. Um einen Isolierverbund zu schaffen, der Schubspannungen aufzunehmen in der Lage ist, ist nach der EP 0 829 609 das Rahmenprofil von zwei Profil-teilen, einer äußeren und einer inneren Profilhälfte, gebildet. Diese sind über ein oder mehrere zwischengefügtes/-te Isolierprofil/-le miteinander verbunden, wobei diese/-s Isolierprofil/-le als die Profilhälften verbindende Hart-Kunststoffstege ausgebildet ist/sind. Ein solcher Isolierverbund erfüllt zwar den Zweck der Isolation und unterbindet einen Wärmeabfluss von innen nach außen im Winter bzw. von außen nach innen im Sommer; er ist auch in der Lage, Schubspannungen aufzunehmen. Treten jedoch erhebliche Temperaturdifferenzen zwischen den Profilhälften auf - solche Temperaturdifferenzen können ohne weiteres Werte von um 50K ereichen - längt oder verkürzt sich je nach Temperatur das eine der Profilhälften gegenüber der anderen, so dass sich ein aus solchen Profilhälften gefertigter Rahmen einer Tür oder eines Fensters zur Seite des kürzeren der Profilhälfte hin ausbiegt; dieses Ausbiegen hat neben unerwünschten Spannungen im Rahmen auch unerwünschte Falz-Undichtheiten zur Folge.To windows or doors with metal, especially with aluminum frame produce, which has sufficient heat insulation is known. to apply a second frame to a first frame. being both with corresponding fillings are provided, and both as Isolierverbund are kept at a distance by spacer blocks. This forms the Air layer between the two frames in connection with the material and the cross section of the spacer blocks the heat flow limiting heat insulation. In this construction, the two frames essentially independent of each other, so that the Isolierverbund is unable to absorb shear stresses. To an insulation composite to create, which is able to absorb shear stresses is according to EP 0 829 609 the frame profile of two profile parts, one outer and an inner profile half formed. These are about one or several interposed / -te Isolierprofil / -le interconnected, wherein these / -s insulating profile / -le connecting the profile halves Hard plastic webs is / are formed. Such an insulation composite Although fulfills the purpose of insulation and prevents heat dissipation from inside to outside in winter or from outside to inside in summer; he is also able to absorb shear stresses. However, significant Temperature differences between the profile halves on - such temperature differences can easily reach values of around 50K - lengthens or shortens depending on the temperature of one of the profile halves opposite the other, so that one made of such profile halves Frame of a door or a window to the side of the shorter of Profile half bends out; This bending has besides unwanted Tension in the frame also results in undesirable seam leaks.

Zum Vermeiden solcher Erscheinungen schlägt DE-GM 296 23 019 vor. dass das in einem Längsverbindungsbereich zwischen den mit einem Kunststoff-Verbindungsprofil verbundenen Profilhälften eines Aluminiumprofils die Schubfestigkeit gering sein soll und etwa gegen Null geht, oder dass eine Gleitführung vorhanden sein soll; dies wird z.B. dadurch erreicht, dass in sämtlichen Längsverbindungsbereichen zwischen den Profilhälften und dem Kunststoff-Isolierprofil die Schubfestigkeit gering ist oder die Gleitverbindung vorgesehen ist. während der Längsverbindungsbereich zwischen der anderen Profilhälfte und dem Kunststoff-Isolierprofil eine hohe Schubfestigkeit aufweist. Alternativ wird vorgeschlagen, das Kunststoff-Verbindungsprofil zu teilen und die Teilung als Gleitführung auszubilden; auch hier wird erreicht, dass der durch diese Teilung gegebene Längsverbindungsbereich eine geringe Schubfestigkeit aufweist. Diese durch die geringe Schubfestigkeit gegebene freie Bewegbarkeit des einen der Profilhälften gegenüber dem anderen hat jedoch eine Labilität des Rahmens insgesamt zur Folge. Darüber hinaus erschwert diese Ausbildung auch wirtschaftliche Fertigungen, da die gegeneinander verschiebbaren Profilhälften der Schenkel des Rahmens vor dem Zusammenfügen zum Rahmen eine Lose aufweisen und so in ihrer Handhabung erheblich erschwert sind. To avoid such phenomena DE-GM proposes 296 23 019 in front. that in a longitudinal connection area between those with a Plastic connecting profile connected profile halves of an aluminum profile the shear strength should be low and about zero goes, or that a sliding guide should be present; this is e.g. achieved in that in all longitudinal connection areas between the profile halves and the plastic insulating profile shear resistance is low or the sliding connection is provided. while the longitudinal connection area between the other profile half and the plastic insulating profile has a high shear resistance. Alternatively, it is proposed to the plastic connection profile divide and form the division as a sliding guide; here too achieved that given by this division longitudinal connection area has a low shear resistance. These by the low Shear strength given free mobility of one of the profile halves However, compared to the other one has a lability of the frame overall result. In addition, this training also complicates economic production, as the mutually displaceable profile halves the leg of the frame before joining to the frame have a lot and so much more difficult to handle are.

Somit ergibt sich die Aufgabe der Erfindung, den bekannten Stand der Technik so weiterzubilden, dass solche Spannungen und damit Falz-Undichtheiten bei erhaltener Isolation und hinreichender Festigkeit der Rahmenverbindung vermieden werden, wobei der Isolierverbund einfach und wirtschaftlich herstellbar sowie einfach einsetzbar sein soll; in Weiterführung der Aufgabenstellung soll ein Rahmen für eine Tür bzw. für ein Fenster so weitergebildet werden, dass das Ausbiegen bei Temperaturdifferenzen zwischen der äußeren und der inneren Profilhälfte unterbunden ist.Thus, the object of the invention, the known The prior art so educate that such voltages and thus Crimp leaks with preserved insulation and sufficient strength the frame connection can be avoided, the Isolierverbund simple and economical to produce and easy to use should; in continuation of the task should be a framework for a Door or for a window to be developed so that the bending out at temperature differences between the outer and inner profile half is prevented.

Diese Aufgabe wird nach der Erfindung durch die Merkmale das Hauptanspruchs gelöst: vorteilhafte Weiterbildungen und bevorzugte Ausführungsformen ergeben sich aus den Unteransprüchen.This object is achieved according to the invention by the features Main claim solved: advantageous developments and preferred Embodiments emerge from the subclaims.

Das Isolierprofil weist im Querschnitt einen ausgebauchten Mittelabschnitt auf. Diese Ausbauchung des Mittelabschnitts ist beidseits mit abstehenden, mit den Profilteilen formschlüssig verbindbaren Stegen versehen. Weiter sind an der Ausbauchung beidseits diese fortsetzende Nasen vorgesehen, auf die ein durchlaufendes Verbinderprofil mit beidseits längsverlaufenden Nuten aufgesetzt ist. die die Nasen formschlüssig unter Bildung einer in Querrichtung festen Verbindung aufnehmen. Die Ausbauchung des Isolierprofils ist zumindest in einem Bereich in Längsrichtung aufgetrennt.The insulating profile has a bulged in cross section Middle section on. This bulge of the middle section is bilateral with protruding, positively connected with the profile parts Provided with bars. Next are on the bulge on both sides this continuing noses provided on the one continuous connector profile is placed on both sides with longitudinal grooves. the the Noses form-fitting to form a transversely solid connection take up. The bulge of the insulating profile is at least separated in a region in the longitudinal direction.

Die feste Verbindung erlaubt die Aufnahme von Längskräften und ermöglicht ein erleichtertes Handhaben der vorgefertigten, noch nicht zum Rahmen verbundenen Profile, da die beiden Profilhälften sich gegeneinander nicht mehr verschieben können. Durch das Auftrennen der Ausbauchung wird das an sich einstückige Isolierprofil lediglich im Bereich der Auftrennung zweistückig und gewinnt dort die Lose, um einseitigen Dehnungen nachgeben zu können: In diesem Offenbereich können sich ungleiche Längenänderungen der beiden Profilteile ausgleichen. Dazu ist die in Querrichtung feste Verbindung zwischen den Nasen des Isolierprofils und dem Verstärkungsprofil in Längsrichtung nicht starr, was das gewünschte Auffangen einer Längenänderung ermöglicht.The solid connection allows the absorption of longitudinal forces and allows easier handling of the prefabricated, not yet connected to the frame profiles, since the two profile halves against each other can not move anymore. By separating the Bumping is the intrinsically insulating profile only in the Area of separation two-piece and win there the lots to to be able to yield to one-sided strains: in this open area can compensate for unequal length changes of the two profile parts. This is the solid in the transverse direction connection between the Noses of the insulating profile and the reinforcing profile in the longitudinal direction not rigid, which allows the desired interception of a change in length.

In den nicht aufgetrennten Bereichen verhindert ein aufgesetztes Verstärkungsprofil ein Öffnen der Ausbauchung durch "Aufbiegen". es werden Festbereiche gebildet; in den aufgetrennten Bereichen, den Losebereichen, bildet das Verstärkungsprofil die Klammer, die die nun getrennten Profilhälften des Isolierprofils zusammenhält. Vorteilhaft weist die Ausbauchung einen OMEGA-förmigen Querschnitt auf.In the unseparated areas prevents an attached Reinforcement profile opening the bulge by "bending". solid areas are formed; in the separated areas, the Loose areas, the reinforcing profile forms the bracket, which now holding separate profile halves of the insulating profile together. Advantageous The bulge has an OMEGA-shaped cross-section.

Um eine sichere und starre Quer-Verbindung zwischen den Nasen des Isolierprofils und dem Verstärkungsprofil ohne eine Längsverschiebbarkeit des auf das Isolierprofil aufgesetzten Verstärkungsprofils zu erreichen, weisen die die Ausbauchung fortsetzenden Nasen einen Querschnitt auf, der den Querschnitt der Nuten des Verbinderprofils in Querrichtung voll, rechtwinklig zur Querrichtung jedoch nicht voll ausfüllt.To ensure a secure and rigid cross-connection between the noses the Isolierprofils and the reinforcing profile without a longitudinal displacement of the reinforcing profile placed on the insulating profile to reach, have the bulging continued noses one Cross-section on the cross section of the grooves of the connector profile full in the transverse direction, but not at right angles to the transverse direction fully filled.

Ein Rahmen für eine Tür, ein Fenster o.dgl. wird durch im wesentlichen U-förmig zusammengefügte Profilen aus Aluminium gebildet. deren beide Längs-Profile über ein oberes Quer-(Profile verbunden sind. wobei das untere Ende des Rahmens mit einem entsprechenden Abschluss ggf. mit einem unteren Querprofil- gebildet ist. Jedes dieser Profile besteht aus eine(m)r äußeren Profilhälfte und einer inneren Profilhälfte. die beide mittels der Isolierleiste mit Verstärkungsprofil zu einem Isolierverbund verbunden sind.A frame for a door, a window or the like. is essentially through U-shaped joined profiles made of aluminum. whose two longitudinal profiles connected via an upper transverse (profiles are. the lower end of the frame with a corresponding conclusion possibly formed with a lower transverse profile. Each of these Profile consists of a (m) r outer profile half and an inner Profile half. both by means of the insulating strip with reinforcing profile are connected to an insulating composite.

Für den Schließschenkel des Rahmens weist dieses Isolierprofil nun zumindest im Bereich dieses Schließschenkels mindestens einen Losebereich auf. Dies ist in vielen Fällen bereits ausreichend. um Ausbiegungen wegen unterschiedlicher Temperaturen von den von den inneren bzw. äußeren Profilhälften gebildeten Innen- und Außenrahmen zu unterdrücken. Alternativ weist dieses Isolierprofil für den Anschlagschenkel des Rahmens mindestens einen Losebereich auf. Sofern ein Losebereich in einem der Schenkel nicht ausreicht, sind vorteilhaft beide Längsprofile des Rahmens mit Isolierprofilen versehen, die sowohl im Bereich des Schließschenkels als auch im Bereich des Anschlagschenkels des Rahmens je mindestens einen Losebereich aufweisen. Dabei sind in einer Weiterbildung die beiden Losebereiche symmetrisch zueinander angeordnet.For the closing leg of the frame, this insulating profile at least in the area of this closing leg at least one loose area on. This is already sufficient in many cases. around bends because of different temperatures from those of the inner ones or outer profile halves formed inner and outer frames suppress. Alternatively, this insulating profile for the stop leg of the frame on at least one loose area. If a lot area in one of the legs is insufficient, are advantageous both longitudinal profiles of the frame provided with insulating profiles, both in the area of the closing leg as well as in the area of the stop leg of the frame each have at least one loose area. In a further development, the two loose areas are symmetrical arranged to each other.

Bei einer bevorzugten Ausbildung umfassen die Losebereiche des/der Isolierprofils/-profile den Bereich der Eckverbindungen zwischen den Längs-Aluminiumprofilen und dem oberen Quer-Aluminiumprofil des Rahmens. Hier ist auch dieses obere Quer-Aluminiumprofil mit zumindest einem Losebereich versehen, der den Eckbereich zu dem Schenkel hin umfasst. der mit einem Losebereich versehen ist, so dass diese beiden Losebereiche ineinander übergehen. Wenn beide Schenkel Losebereiche aufweisen, wird das Quer-Aluminiumprofils mit zwei Losebereichen versehen, die beidseits im Bereich der Eckverbindung vorgesehen sind. Damit kann/können der/die Losebereich/-bereiche die Eckverbindung/-en des Rahmens diese übergreifend umfassen. So wird ein Ausbiegen des Eckbereichs des Rahmens sicher unterbunden.In a preferred embodiment, the looseness areas comprise of the Isolierprofils / profiles the range of corner joints between the longitudinal aluminum profiles and the upper transverse aluminum profile of the frame. Here is also this upper transverse aluminum profile with at least a looser area which the corner area to the leg includes. which is provided with a loose area, so this merge into two lots. If both thighs loose areas have the transverse aluminum profile with two loose areas provided on both sides in the region of the corner joint are. Thus, the loose area (s) may / may be the corner joint (s) of the framework encompassing them. This is how it is Bending out of the corner of the frame safely prevented.

Vorteilhaft ist der Festbereich so angeordnet, dass er sich etwa über 1/3 der Länge des/der Längs-Aluminiumprofils/-le erstreckt. Bei dieser Anordnung sind etwa 3/6 der der oberen Ecke des Rahmens zugeordneten Länge des Längs-Aluminiumprofils und etwa 1/6 der der unteren Ecke des Rahmens zugeordneten Länge des Längs-Aluminiumprofils als Losebereiche ausgebildet, in denen die Ausbauchungen eine Auftrennung aufweisen. Mit dieser Anordnung wird eine symmetrische und gegen Ausbiegungen sichere Rahmenkonstruktion geschaffen, die einfach herzustellen ist. Diese einfache Herstellbarkeit hat ihren Grund in der einfachen Handhabbarkeit der einzelnen zum Isolierverbund zusammengefügten Aluminiumprofile; dabei wird das Auftrennen der Ausbauchung des Isolierprofils nach dem Zusammenfügen der abgelängten Aluminiumprofil-Abschnitte in einer Vorrichtung mit einem entsprechenden Fingerfräser. einem Kreissägeblatt o.dgl. vorgenommen.Advantageously, the fixed area is arranged so that he himself extending over about 1/3 the length of the longitudinal aluminum profile (s). In this arrangement, about 3/6 of the upper corner of the frame assigned length of the longitudinal aluminum profile and about 1/6 of the bottom corner of the frame associated length of the longitudinal aluminum profile designed as loose areas in which the bulges a Have separation. With this arrangement, a symmetrical and created against bends secure frame construction, the easy to make. This ease of manufacture has their Reason in the ease of handling of the individual to Isolierverbund assembled aluminum profiles; thereby the separation of the Bulging of the insulating profile after joining the cut to length Aluminum profile sections in a device with a corresponding End mill. a circular saw blade or the like. performed.

Jedes der Aluminium-Profile 10 wird - wie in Figur 2 dargestellt, von zwei stranggepressten Profilhälften 11 und 15 gebildet: jede dieser Profilhälften 11 bzw. 15 weist einen äußeren Profilschenkel 12 bzw. 16 auf, sowie einen inneren Profilschenkel 13 bzw. 17, die zusammen mit quer verlaufenden (nicht näher bezeichneten) Profilschenkeln je eine Kammer umschließen. Um eine thermische Trennung zu erreichen, sind die beiden Profilhälften 11 und 15 über wärmeisolierende Isolierprofile 20 zusammengefügt. Dazu weisen die inneren Profilschenkel 13 bzw. 17 im Abstand voneinander vorgesehene Nuten 14 bzw. 18 auf, in die beidseits am Isolierprofil 20 etwa rechtwinklig abstehende Stege 21 formschlüssig einsetzbar sind; dabei sind die Nuten 14 bzw. 18 und die Stege so ausgebildet, dass sie Hintergreifungselemente aufweisen, die ein Herausziehen in Richtung der Stege 21 unterbinden.Each of the aluminum profiles 10 is - as shown in Figure 2, formed by two extruded profile halves 11 and 15: Each of these profile halves 11 and 15 has an outer profile leg 12 and 16, and an inner profile leg 13 and 17, the together with transverse (unspecified) profile legs each enclosing a chamber. To a thermal break too reach, the two profile halves 11 and 15 on heat insulating Isolierprofile 20 joined together. For this purpose, the inner profile legs 13 and 17 provided at a distance from each other grooves 14th or 18, in the two sides of the insulating profile 20 approximately at right angles projecting webs 21 are positively inserted; Here are the grooves 14 and 18 and the webs are formed so that they are behind engagement elements have, which pull out in the direction of the webs 21 prevent.

Die in den Figuren 2 und 3 vergrößert dargestellten Isolierprofile 20 werden vorteilhaft als Kunststoff-Extrusionprofile hergestellt. so dass sie ohne weiteres abgelängt eingesetzt werden können. Mittig sind diese Isolierprofile 20 mit einer Ausbauchung 22 versehen, die in der Darstellung OMEGA-förmig ausgebildet ist, ohne Beschränkung auf diese Ausformung. Die Ausbauchung 22 setzt sich durch die Nasen 23 in Gegenrichtung fort. Diese Nasen 23 wirken mit einem Verstärkungsprofil 25 zusammen, das vorteilhaft als stranggepresstes Leichtmetall-Profil ausgebildet ist.The insulating profiles shown enlarged in Figures 2 and 3 20 are advantageously prepared as plastic extrusion profiles. so that they can be used cut to length without further ado. In the middle of these insulating profiles 20 are provided with a bulge 22, which is formed in the representation OMEGA-shaped, without limitation to this shape. The bulge 22 prevails the noses 23 in the opposite direction away. These noses 23 act with a Reinforcement 25 together, which is advantageous as extruded Light metal profile is formed.

Dieses Verstärkungsprofil 25 ist von der Ausbauchung 22 aus gesehen von rückwärts aufgesetzt; es verleiht dem Isolierprofil 20 die notwendige Stabilität und nimmt die die beiden Profilteile 11 und 16 der Rahmenprofile 10 zusammenhaltenden Kräfte auf. In seiner Grundform weist dieses Verstärkungsprofil 25 einen etwa dreikantigen Querschnitt mit einer Spitze auf, die als Nase 26 zwischen die beiden den Scheitel 24 rückwärts fortsetzenden Nasen 23 des Isolierprofils 20 liegt. In die beiden sich an diese Spitze anschließenden Seiten dieses dreieckigen Querschnitts sind längsverlaufende Nuten 27 eingebracht, in die die an der Ausbauchung 22 beidseits vorgesehenen, diese fortsetzenden Nasen 23 des Isolierprofils 20 eingreifen. Diese Nasen 23 werden von den Nuten 27 etwa formschlüssig aufgenommen, wobei der Formschluss erlaubt, eine in Richtung der Stege 21 wirkende Längskraft aufzunehmen. Durch dieses Verstärkungsprofil 25 wird die an sich wenig stabile Verbindung der beiden Profilhälften 11 und 15 so ausgesteift, dass eine in Querrichtung unnachgiebige, starre Verbindung entsteht.This reinforcing profile 25 is protruding from the bulge 22 seen from the back; it gives the insulating profile 20th the necessary stability and takes the two profile parts 11 and 16 of the frame profiles 10 holding forces together. In its Basic form, this reinforcing profile 25 has an approximately dreikantigen Cross-section with a tip on, acting as nose 26 between the two the apex 24 backward continuing lugs 23 of the insulating profile 20 lies. In the two sides following this tip this triangular cross-section longitudinal grooves 27 are introduced, in which provided on the bulge 22 on both sides, this continuing noses 23 of the insulating profile 20 engage. These noses 23 are approximately positively received by the grooves 27, wherein the positive connection allows, acting in the direction of the webs 21 Absorb longitudinal force. By this reinforcing profile 25 is the in itself little stable connection of the two profile halves 11 and 15th so stiffened that a transversely unyielding, rigid connection arises.

Um einen Längenausgleich zu erreichen, ist nun der Scheitel 24 der Ausbauchung 22 zumindest in einem Teilbereich der Isolierprofile 20 aufgetrennt. so dass eine Auftrennung 24.1 entsteht. Diese Auftrennung 24.1 hebt die starre Verbindung zwischen den beiden so entstandenen Teilen des Isolierprofils 20 in diesen Bereichen auf, so dass sich ein Losebereich bildet. der für einen Längenausgleich hinreichend ist; die verbleibenden Festbereiche 24 sichern dabei den Zusammenhalt.To achieve a length compensation, the vertex is now 24 the bulge 22 at least in a portion of the insulating profiles 20 separated. so that a separation 24.1 arises. This separation 24.1 lifts the rigid connection between the two thus created Divide the insulating profile 20 in these areas, so that forms a loose area. the sufficient for a length compensation is; the remaining fixed areas 24 ensure cohesion.

Die Figur 4 zeigt als Anwendungsbeispiel den - hier U-förmig dargestellten - Rahmen einer Tür 1. der aus den Aluminium-Profilen 10 (Fig. 1 - 3) zusammengesetzt ist. Die beiden vertikalen der Profile 10 bilden dabei die Längsprofile 2 und das oben querliegende der Profile 10 das Querprofil 3 des Rahmens (wobei es sich von selbst versteht, dass auch ein unteres Querprofil vorgesehen sein kann). Die Längsprofile 2 und das Querprofil 3 stoßen in den beiden Eckbereichen zusammen, wo sie auch zusammengefügt sind. Das eine der Längsprofile 2 ist mit den Scharnierteilen 4 versehen und bildet den Anschlagschenkel 2.1; das gegenüberliegend angeordnete der Längsprofile 2 ist mit Drückergarnitur und Schloss 5 versehen und bildet den Schließschenkel 2.2. In diesem Rahmen ist die Türfüllung 9 eingesetzt. Vorteilhaft befinden sich die Festbereiche 6 mit den Isolierprofilen 20. deren Scheitel 24 nicht aufgetrennt sind, in den unteren Teilen der Längsprofile 10.1 (wie in Fig. 4 angedeutet), die Losebereiche 7. in denen die Isolierprofile 20 Scheitel mit der Auftrennung 24.1 aufweisen, erstrecken sich beidseits davon, so dass beide Eckbereiche von Losebereichen 7 überdeckt sind. Der Festbereich 6 für das Querprofil 10.2 ist dagegen symmetrisch zur Mitte abgeordnet.FIG. 4 shows an application example of the - here U-shaped shown - the frame of a door 1. from the aluminum profiles 10th (Fig. 1 - 3) is composed. The two vertical of the profiles 10 form the longitudinal profiles 2 and the above transverse of the profiles 10 the cross section 3 of the frame (it goes without saying, that a lower transverse profile can be provided). The Longitudinal profiles 2 and the transverse profile 3 abut in the two corner areas together, where they are put together. One of the longitudinal profiles 2 is provided with the hinge parts 4 and forms the stop leg 2.1; the oppositely disposed of the longitudinal profiles 2 is equipped with handle set and lock 5 and forms the closing leg 2.2. In this context, the door panel 9 is inserted. Advantageous are the fixed areas 6 with the insulating profiles 20th whose vertices 24 are not separated, in the lower parts of the Longitudinal profiles 10.1 (as indicated in Fig. 4), the Losebereiche 7. in to which the insulating profiles 20 have vertices with the separation 24.1, extend on both sides of it, so that both corner areas of Loose areas 7 are covered. The fixed area 6 for the cross profile 10.2 on the other hand is seconded symmetrically to the middle.
