Description

Die vorliegende Erfindung betrifft ein Verbundprofil für Fenster, Festverglasungen, Fassaden, Türen oder Lichtdächer, ein Metallprofil zu dessen Herstellung sowie ein Verfahren zu dessen Herstellung gemäss den Oberbegriffen der unabhängigen Patentansprüche.The present invention relates to a composite profile for windows, fixed glazing, facades, doors or skylights, a metal profile for its production and a method for its production according to the preambles of the independent claims.

Um eine möglichst geringe Wärmeleitung zu erreichen, werden Metallprofile für Aussenverglasungen wie Fenster, Türen und Glassfassaden als Verbundprofile ausgebildet, derart, dass thermisch relativ gut leitende Teilprofile aus Metall über Isolierstege aus Kunststoff zu einem Verbundprofil miteinander verbunden werden.In order to achieve the lowest possible heat conduction, metal profiles for external glazing such as windows, doors and glass facades are formed as composite profiles, such that thermally relatively good conductive metal sub-profiles are connected to each other via insulating webs made of plastic to a composite profile.

Hierzu werden die Isolierstege in Befestigungsnuten in den Metallprofilen angeordnet und sodann durch Zusammenpressen der Befestigungsnuten, z.B. durch Anrollen, gegebenenfalls unter zusätzlicher Einbringung von in den Isoliersteg eindringenden Prägungen, mit den Metallprofilen verbunden.For this purpose, the insulating webs are arranged in fastening grooves in the metal profiles and then by compressing the fastening grooves, e.g. by rolling, optionally with the additional introduction of penetrating into the insulating embossings, connected to the metal profiles.

Dabei ergibt sich jedoch das Problem, dass eine feste Verbindung nur dann sichergestellt werden kann, wenn das elastische Zurückfedern der die Seitenbegrenzungen der jeweiligen Befestigungsnut bildenden Profilabschnitte nach dem Zusammenpressen in engen Grenzen gehalten werden kann und nach dem Zusammenpressen auch eine ausreichende Steifigkeit gegen ein Aufbiegen der Profilnut gegeben ist.However, there is the problem that a firm connection can only be ensured if the elastic spring back of the side boundaries of the respective mounting groove forming profile sections can be kept within narrow limits after compression and after compression also sufficient rigidity against bending of the Profilnut is given.

Bei Metallprofilen, welche durch Umformen aus einem Blechmaterial gebildet sind, wird dies heute dadurch erreicht, dass die die Seitenbegrenzungen der Befestigungsnuten bildenden Profilabschnitte jeweils gemeinsam von einem U-förmigen Profilabschnitt gebildet werden. Dies hat jedoch den Nachteil, dass die Gestaltungsmöglichkeiten betreffend die übrige Profilkontur hierdurch stark eingeschränkt werden. So sind beispielsweise Profilkonturen, bei denen die die Seitenbegrenzungen einer Befestigungsnut bildenden Profilabschnitte über einen Profilabschnitt miteinander verbunden sind, in welchem die Profilkontur eine Profilschleife beschreibt, nicht möglich oder würden enorme Blechstärken erfordern.In metal profiles, which are formed by forming from a sheet material, this is achieved today in that the side boundaries of the fastening grooves forming profile sections are each formed together by a U-shaped profile section. However, this has the disadvantage that the design options concerning the rest of the profile contour are severely limited. For example, profile contours where the side boundaries a profile groove forming profile sections are connected to each other via a profile section in which the profile contour describes a profile loop, not possible or would require enormous sheet thicknesses.

Es stellt sich daher die Aufgabe, technische Lösungen zur Verfügung zu stellen, welche den zuvor genannten Nachteil des Standes der Technik nicht aufweisen oder zumindest teilweise vermeiden.It is therefore an object to provide technical solutions that do not have the aforementioned disadvantage of the prior art or at least partially avoided.

Diese Aufgabe wird von dem Verbundprofil, dem Metallprofil zu dessen Herstellung und dem Verfahren zu dessen Herstellung gemäss den unabhängigen Patentansprüchen gelöst.This object is achieved by the composite profile, the metal profile for its production and the process for its preparation according to the independent claims.

Demgemäss betrifft ein erster Aspekt der Erfindung ein Verbundprofil für Fenster, Festverglasungen, Fassaden, Türen oder Lichtdächer. Das Verbundprofil umfasst mindestens ein Isolierprofil aus einem Material mit einer im Vergleich zu Metall geringen Wärmeleitfähigkeit, bevorzugterweise aus einem Kunststoffmaterial, sowie mindesten ein Metallprofil, welches durch Umformen, insbesondere durch Rollen, aus einem Blechmaterial gebildet worden ist.Accordingly, a first aspect of the invention relates to a composite profile for windows, fixed glazings, facades, doors or skylights. The composite profile comprises at least one insulating profile of a material having a low thermal conductivity compared to metal, preferably of a plastic material, and at least one metal profile, which has been formed by forming, in particular by rolling, of a sheet material.

Das mindestens eine Metallprofil, welches z.B. aus Aluminium, Stahl blank bzw. verzinkt oder aus Edelstahl bestehen kann, bildet eine Befestigungsnut mit zwei sich gegenüberliegenden Seitenbegrenzungen, welche bevorzugterweise aus einfachen nicht gedoppelten Blechen bestehen, und einem Nutgrund, in welcher eine Profilkontur des Isolierprofils aufgenommen ist, unter Bildung eines Kraft- und/oder Formschlusses in einer Richtung senkrecht zur Profillängsrichtung von Nutgrund wegzeigend zwischen dem Isolierprofil und den Seitenbegrenzungen der Befestigungsnut bzw. dem Metallprofil. Bevorzugterweise liegt zudem auch ein Formschluss zwischen dem Isolierprofil und den Seitenbegrenzungen der Befestigungsnut bzw. dem Metallprofil in Profillängsrichtung vor.The at least one metal profile, which e.g. made of aluminum, bare steel or galvanized or made of stainless steel, forms a mounting groove with two opposite side boundaries, which preferably consist of simple non-doubled sheets, and a groove base, in which a profile contour of the insulating profile is added, to form a force and / or positive locking in a direction perpendicular to the profile longitudinal direction of groove base pointing away between the insulating profile and the side boundaries of the mounting groove or the metal profile. Preferably, moreover, there is also a positive connection between the insulating profile and the side boundaries of the fastening groove or the metal profile in the profile longitudinal direction.

Dabei ist das Metallprofil derartig ausgebildet, dass die beiden Seitenbegrenzungen der Befestigungsnut von zwei Profilabschnitten gebildet sind, welche über einem oder mehrere Profilabschnitte miteinander verbunden sind, in welchen die Profilkontur eine Profilschleife beschreibt. Dabei kann die Profilschleife einen Profilhohlraum bilden und/oder eine Blechdoppelung, bei welcher Profilabschnitte der Profilschleife flächig aneinander angrenzen bzw. aufeinanderliegen.In this case, the metal profile is designed such that the two side boundaries of the mounting groove are formed by two profile sections, which are interconnected via one or more profile sections, in which the profile contour describes a profile loop. In this case, the profile loop can form a profile cavity and / or a sheet metal double, in which profile sections of the profile loop adjoin one another in a planar manner or lie on one another.

In einem oder in mehreren Bereichen der Profilschleife grenzen Profilabschnitte der Profilschleife aneinander an bzw. liegen aufeinander. Dabei sind sie zumindest in einem dieser Bereiche, in welchen sie aneinander angrenzen bzw. aufeinanderliegen, miteinander verbunden.In one or more regions of the profile loop, profile sections of the profile loop adjoin one another or rest on one another. At least in one of these areas, in which they adjoin one another or lie on top of each other, they are connected to one another.

Durch diese Massnahme ist der Teil der Profilschleife, der durch die Verbindung zwischen den aneinander angrenzenden Profilabschnitten geschlossen wird, aus der für die Steifigkeit zwischen den beiden die Seitenbegrenzungen der Befestigungsnut bildenden Profilabschnitten verantwortlichen Profilstruktur ausgeschlossen, mit dem Resultat, dass auch mit relativ geringen Blechstärken eine hohe Steifigkeit gegen ein Aufbiegen der Profilnut erzielbar ist und zudem die Rückfederungsneigung dieser Abschnitte bei der Herstellung der Verbindung zwischen dem Isolierprofil und dem Metallprofil gering ist.By this measure, the part of the profile loop, which is closed by the connection between the adjoining profile sections, excluded from the responsible for the rigidity between the two side boundaries of the mounting groove profile sections profile structure, with the result that even with relatively small plate thicknesses high rigidity against bending of the profile is achievable and also the resilience of these sections in the preparation of the connection between the insulating profile and the metal profile is low.

Bevorzugterweise ist das Isolierprofil aus glasfaserverstärktem pultrudierten Polyurethan gebildet. Dieser Kunststoff kann durch die Glasfaserverstärkung grosse Kräfte aufnehmen und erhöht die statische Wirkung des Profils bei gleichzeitiger Minimierung der Wärmeleitfähigkeit des Verbundprofiles. Polyurethan ist ein hochwertiger Kunststoff mit sehr guten Eigenschaften bezüglich Beständigkeit und Alterungsverhalten, womit eine langlebige Konstruktion sichergestellt werden kann. Es können aber auch andere Materialien zum Einsatz kommen, dies in Abhängigkeit von der geforderten Wärmeleitfähigkeit, den notwendigen statischen Eigenschaften und allfälligen brandschutztechnischen Vorgaben.Preferably, the insulating profile of glass fiber reinforced pultruded polyurethane is formed. This plastic can absorb large forces through the glass fiber reinforcement and increases the static effect of the profile while minimizing the thermal conductivity of the composite profile. Polyurethane is a high-quality plastic with very good properties in terms of resistance and aging behavior, which ensures a durable construction. However, other materials may also be used, depending on the required thermal conductivity, the necessary static properties and any fire protection requirements.

In einer bevorzugten Ausführungsform des Verbundprofils grenzen Profilabschnitte der Profilschleife in einem Bereich direkt angrenzend an einen der Profilabschnitte, welche die Seitenbegrenzungen der Befestigungsnut bilden, aneinander an bzw. liegen aufeinander und sind in diesem Bereich miteinander verbunden. Hierdurch wird ein möglichst grosser Teil der Profilschleife oder sogar die gesamte Profilschleife aus der für die Steifigkeit zwischen den beiden die Seitenbegrenzungen der Befestigungsnut bildenden Profilabschnitten verantwortlichen Profilstruktur ausgeschlossen.In a preferred embodiment of the composite profile, profile sections of the profile loop adjoin one another in a region directly adjacent to one of the profile sections which form the lateral boundaries of the fastening groove and are connected to one another in this region. As a result, the largest possible part of the profile loop or even the entire profile loop is excluded from the profile structure responsible for the rigidity between the two profile boundaries forming the lateral boundaries of the fastening groove.

In einer weiteren bevorzugten Ausführungsform des Verbundprofils ist die Profilschleife zum Teil oder vollständig als Blechdoppelung ausgebildet, also derart, dass Profilabschnitte dieser Profilschleife in Teilbereichen oder über den gesamten Bereich der Profilschleife flächig aneinander angrenzen, und zwar bevorzugterweise in Form flacher aufeinanderliegender Profilabschnitte. Derartige Blechdoppelungen eignen sich besonders zur Bereitstellung flacher flanschartiger Profilkonturen mit gradfreien Begrenzungskanten und ermöglichen zudem ein flächiges Verbinden der aneinander angrenzenden bzw. aufeinanderliegenden Profilabschnitte der Profilschleife, z.B. durch Verlöten.In a further preferred embodiment of the composite profile, the profile loop is partially or completely formed as a sheet metal doubling, ie in such a way that profile sections of this profile loop adjoin one another in partial regions or over the entire region of the profile loop, preferably in the form of flat, superimposed profile sections. Sheet metal doublings of this kind are particularly suitable for providing flat flange-like profile contours with non-cutting boundary edges and moreover enable planar connection of the adjoining or superimposed profile sections of the profile loop, e.g. by soldering.

Jedenfalls ist es bei solchen Ausführungsformen des Verbundprofils mit Blechdoppelung bevorzugt, dass die aneinander angrenzenden Profilabschnitte der Profilschleife zumindest im Bereich des zum offenen Ende der Profilschleife hin zeigenden Endes der Blechdoppelung miteinander verbunden sind. Hierdurch wird ein möglichst grosser Teil der Blechdoppelung aus der für die Steifigkeit zwischen den beiden die Seitenbegrenzungen der Befestigungsnut bildenden Profilabschnitten verantwortlichen Profilstruktur ausgeschlossen.In any case, it is preferred in such embodiments of the composite profile with sheet metal doubling that the adjoining profile sections of the profile loop are connected to each other at least in the region of the open end of the profile loop end facing the sheet metal doubling. As a result, the largest possible part of the sheet metal doubling is excluded from the profile structure responsible for the rigidity between the two profile boundaries forming the lateral boundaries of the fastening groove.

In einer weiteren bevorzugten Ausführungsform des Verbundprofils sind die aneinander angrenzenden Profilabschnitte der Profilschleife stoffschlüssig miteinander verbunden, insbesondere durch Laserschweissen, Rollschweissen, Löten oder Kleben. Da durch diese Verbindungsmethoden eine von aussen her unsichtbare Verbindung der Profilabschnitte möglich ist, können auf diese Weise auch Profilabschnitte der Profilschleife miteinander verbunden werden, welche glatte Sichtflächen des fertigen Verbundprofils bilden.In a further preferred embodiment of the composite profile, the adjoining profile sections of the profile loop are connected to one another in a material-locking manner, in particular by laser welding, roll welding, soldering or gluing. Since these connection methods make it possible to connect the profile sections invisibly from the outside, profile sections of the profile loop can also be connected to one another in this way, which form smooth visible surfaces of the finished composite profile.

In noch einer weiteren bevorzugten Ausführungsform des Verbundprofils ist die Verbindung zwischen den aneinander angrenzenden bzw. aufeinander liegenden Profilabschnitten der Profilschleife eine in Profillängsrichtung durchgehende Verbindung. Hierdurch ergibt sich der Vorteil einer über die gesamte Profilerstreckung homogenen Profilstruktur.In yet another preferred embodiment of the composite profile, the connection between the adjoining or superposed profile sections of the profile loop is a continuous connection in the profile longitudinal direction. This results in the advantage of a profile structure which is homogeneous over the entire profile extension.

In einer anderen bevorzugten Ausführungsform des Verbundprofils ist die Verbindung zwischen den aneinander angrenzenden Profilabschnitten der Profilschleife eine in Profillängsrichtung abschnittweise unterbrochene Verbindung, bevorzugterweise mit einer Vielzahl von in regelmässigen Abständen angeordneter identischer Verbindungsstellen. Auf diese Weise kann die Verbindung auf besonders wirtschaftliche Weise hergestellt werden, z.B. durch Punktschweissen.In another preferred embodiment of the composite profile, the connection between the adjoining profile sections of the profile loop is a section which is interrupted in sections in the profile longitudinal direction, preferably with a multiplicity of identical connection points arranged at regular intervals. In this way, the compound can be prepared in a particularly economical manner, e.g. by spot welding.

In noch einer weiteren bevorzugten Ausführungsform des Verbundprofils weist die in der Befestigungsnut des Metallprofils aufgenommene Profilkontur des Isolierprofils auf mindestens einer Seite eine Nut auf, in welche eine Profilkontur des Profilabschnitts des Metallprofils eingreift, welcher die an diese Seite angrenzende Seitenbegrenzung der Befestigungsnut bildet. Hierdurch kann ein sicherer Formschluss in einer Richtung senkrecht zur Profillängsrichtung von Nutgrund wegzeigend zwischen dem Isolierprofil und dem Metallprofil erzeugt werden.In yet another preferred embodiment of the composite profile, the profile contour of the insulating profile received in the fastening groove of the metal profile has a groove on at least one side into which a profile contour of the profile section of the metal profile engages, which forms the side boundary of the fastening groove adjacent to this side. In this way, a positive positive connection in a direction perpendicular to the profile longitudinal direction of groove base pointing away between the insulating profile and the metal profile can be generated.

Wird dabei die Profilkontur, welche in die Nut eingreift, von einer Vielzahl identischer, in Profillängsrichtung mit einem insbesondere gleichmässigen Abstand zueinander angeordneter Prägungen gebildet, was bevorzugt ist, so lässt sich durch Materialverdrängung am Isolierprofil zudem auch ein Formschluss in Profillängsrichtung zwischen dem Isolierprofil und dem Metallprofil erzeugen.If the profile contour, which engages in the groove, formed by a plurality of identical, in the profile longitudinal direction with a particular uniform spacing to each other arranged imprints, which is preferred, so can also be a positive connection in the profile longitudinal direction between the insulating and the profile by material displacement on Isolierprofil Create metal profile.

In noch einer weiteren bevorzugten Ausführungsform des Verbundprofils verjüngt sich die in der Befestigungsnut des Metallprofils aufgenommene Profilkontur des Isolierprofils im Bereich des offenen Endes der Befestigungsnut auf mindestens einer Seite unter Bildung eines Hinterschnitts, in welchen eine Profilkontur des Profilabschnitt des Metallprofils, welcher die an diese Seite angrenzende Seitenbegrenzung der Befestigungsnut bildet, bevorzugterweise mit einem freien Profilende eingreift. Hierdurch kann ebenfalls ein sicherer Formschluss in einer Richtung senkrecht zur Profillängsrichtung von Nutgrund wegzeigend zwischen dem Isolierprofil und dem Metallprofil erzeugt werden.In yet another preferred embodiment of the composite profile, the profile contour of the insulating profile received in the fastening groove of the metal profile tapers in the region of the open end of the fastening groove on at least one side to form an undercut, in which a profile contour of the profile section of the metal profile, which on this side forms adjacent side boundary of the mounting groove, preferably engages with a free profile end. In this way, a positive fit in a direction perpendicular to the profile longitudinal direction of groove base can also be generated pointing away between the insulating profile and the metal profile.

In noch einer weiteren bevorzugten Ausführungsform des Verbundprofils ist das Metallprofil derartig ausgebildet, dass die beiden Profilabschnitte, welche die Seitenbegrenzungen der Befestigungsnut bilden, von den freien Enden der Profilkontur des Metallprofils gebildet sind. Hierdurch werden Verbundprofile mit klar strukturierten Profilkonturen möglich, welche zudem mit einem einzigen Isolierprofil auskommen.In yet another preferred embodiment of the composite profile, the metal profile is formed such that the two profile sections, which form the side boundaries of the mounting groove, are formed by the free ends of the profile contour of the metal profile. As a result, composite profiles with clearly structured profile contours are possible, which also manage with a single insulating profile.

Entsprechend weist das Verbundprofil gemäss einer weiteren bevorzugten Ausführungsform genau ein Isolierprofil auf. Hierdurch lässt sich der Materialaufwand sowie der apparatetechnische Aufwand für die Herstellung der Verbundprofile deutlich reduzieren und es werden zudem auch besonders schlanke Verbundprofile möglich.Accordingly, according to a further preferred embodiment, the composite profile has exactly one insulating profile. As a result, the cost of materials and the technical equipment required for the production of composite profiles can be significantly reduced and it also also very slim composite profiles are possible.

In noch einer weiteren bevorzugten Ausführungsform umfasst das Verbundprofil zwei Metallprofile, bevorzugterweise genau zwei Metallprofile, welche über ein oder mehrere Isolierprofile miteinander verbunden sind. Derartige Verbundprofile aus zwei über Isolierprofile thermisch voneinander getrennten Metallprofilen werden in der Praxis am häufigsten benötigt.In yet another preferred embodiment, the composite profile comprises two metal profiles, preferably exactly two metal profiles, which are interconnected via one or more insulating profiles. Such composite profiles of two insulating profiles thermally separated from each other metal profiles are required in practice most often.

Ein zweiter Aspekt der Erfindung betrifft ein Metallprofil zur Herstellung eines Verbundprofils gemäss dem ersten Aspekt der Erfindung, welches durch Umformen aus einem Blechmaterial gebildet ist. Das Metallprofil weist eine Befestigungsnut mit zwei sich gegenüberliegenden Seitenbegrenzungen zur Aufnahme einer Profilkontur eines damit zu einem Verbundprofil zusammenzufügenden Isolierprofils auf. Dabei ist das Metallprofil derartig ausgebildet, dass die beiden Seitenbegrenzungen der Befestigungsnut von zwei Profilabschnitten gebildet sind, welche über mindestens einen Profilabschnitt miteinander verbunden sind, in welchem die Profilkontur eine Profilschleife beschreibt und wobei Profilabschnitte dieser Profilschleife zumindest in einem Bereich aneinander angrenzen und zumindest in einem Bereich ihrer Angrenzung miteinander verbunden sind. Wie bereits erwähnt wurde, ist durch dieses Verbinden der angrenzenden Profilabschnitte der Profilschleife derjenige Teil der Profilschleife, der durch die Verbindung zwischen den aneinander angrenzenden Profilabschnitten geschlossen wird, aus der für die Steifigkeit zwischen den beiden die Seitenbegrenzungen der Befestigungsnut bildenden Profilabschnitten verantwortlichen Profilstruktur ausgeschlossen, mit dem Resultat, dass auch mit relativ geringen Blechstärken eine hohe Steifigkeit gegen ein Aufbiegen der Profilnut erzielbar ist und zudem die Rückfederungsneigung dieser Abschnitte bei der Herstellung einer Verbindung zwischen einem Isolierprofil und dem Metallprofil zwecks Bildung des Verbundprofils gering ist.A second aspect of the invention relates to a metal profile for producing a composite profile according to the first aspect of the invention, which is formed by forming from a sheet metal material. The metal profile has a fastening groove with two opposite side boundaries for receiving a profile contour of an insulating profile to be assembled therewith into a composite profile. In this case, the metal profile is formed such that the two side boundaries of the mounting groove are formed by two profile sections, which are interconnected via at least one profile section, in which the profile contour describes a profile loop and profile sections of this profile loop adjacent to each other at least in one area and at least in one The area of their adjacency. As already mentioned, by this joining of the adjacent profile sections of the profile loop, that part of the profile loop which is closed by the connection between the adjacent profile sections is excluded from the profile structure responsible for the rigidity between the two profile sections forming the lateral boundaries of the fastening groove the result that even with relatively small sheet thicknesses a high rigidity against bending of the profile groove is achieved and also the resilience of these sections in the preparation of a connection between an insulating profile and the metal profile in order to form the composite profile is low.

In einer bevorzugten Ausführungsform des Metallprofils grenzen Profilabschnitte der Profilschleife in einem Bereich direkt angrenzend an einen der Profilabschnitte, welche die Seitenbegrenzungen der Befestigungsnut bilden, aneinander an und sind in diesem Bereich miteinander verbunden. Hierdurch wird ein möglichst grosser Teil der Profilschleife oder sogar die gesamte Profilschleife aus der für die Steifigkeit zwischen den beiden die Seitenbegrenzungen der Befestigungsnut bildenden Profilabschnitten verantwortlichen Profilstruktur ausgeschlossen und es kann eine maximale Steifigkeit gegen ein Aufbiegen der Befestigungsnut und eine minimale Rückfederungsneigung der die Befestigungsnut begrenzenden Profilabschnitte erreicht werden.In a preferred embodiment of the metal profile, profile sections of the profile loop adjoin one another in an area directly adjacent to one of the profile sections, which form the lateral boundaries of the fastening groove, and are connected to one another in this area. As a result, the largest possible part of the profile loop or even the entire profile loop is excluded from the profile structure responsible for the stiffness between the two the side boundaries of the mounting groove profile sections and it can be a maximum rigidity against bending of the mounting groove and a minimum springback of the mounting groove limiting profile sections be achieved.

Weitere bevorzugte Ausführungsformen des Metallprofils ergeben sich aus den unter dem ersten Aspekt der Erfindung beschriebenen bevorzugten Merkmalen des im dort beschriebenen Verbundprofil verwendeten Metallprofils.Further preferred embodiments of the metal profile result from the preferred features of the metal profile used in the composite profile described in the first aspect of the invention.

Ein dritter Aspekt der Erfindung betrifft ein Verfahren zur Herstellung eines Verbundprofils gemäss dem ersten Aspekt der Erfindung. Bei dem Herstellverfahren wird von einem durch Umformen aus einem Blechmaterial gebildeten Metallprofil ausgegangen. Das Metallprofil weist eine Befestigungsnut mit zwei sich gegenüberliegenden Seitenbegrenzungen auf, welche der Aufnahme einer Profilkontur eines am Metallprofil zu befestigenden Isolierprofils dient. Das Metallprofil ist weiter derartig ausgebildet, dass die beiden Seitenbegrenzungen der Befestigungsnut von zwei Profilabschnitten gebildet sind, welche über einen oder mehrer Profilabschnitte miteinander verbunden sind, in welchen jeweils die Profilkontur eine Profilschleife beschreibt. Dabei grenzen Profilabschnitte der Profilschleife zumindest in einem Bereich aneinander an und sind zumindest in einem Bereich ihrer Angrenzung miteinander verbunden. Es handelt sich bei dem Metallprofil also um ein Metallprofil gemäss dem zweiten Aspekt der Erfindung.A third aspect of the invention relates to a method for producing a composite profile according to the first aspect of the invention. The manufacturing method is based on a formed by forming from a sheet metal material metal profile. The metal profile has a fastening groove with two opposite side boundaries, which serves to receive a profile contour of an insulating profile to be fastened to the metal profile. The metal profile is further formed such that the two side boundaries of the mounting groove are formed by two profile sections which are interconnected via one or more profile sections, in each of which the profile contour describes a profile loop. In this case, profile sections of the profile loop adjoin one another at least in one area and are connected to one another at least in a region of their adjacency. It is the metal profile So a metal profile according to the second aspect of the invention.

In die Befestigungsnut des Metallprofils wird ein Isolierprofil mit einer daran gebildeten Profilkontur eingesetzt. Das Isolierprofil ist bevorzugterweise aus einem Kunststoffmaterial gebildet, bevorzugterweise aus glasfaserverstärktem pultrudierten Polyurethan.In the mounting groove of the metal profile, an insulating profile is used with a profile contour formed thereon. The insulating profile is preferably formed of a plastic material, preferably of glass fiber reinforced pultruded polyurethane.

Sodann wird bei in der Befestigungsnut eingesetztem Isolierprofil durch plastisches Verformen zumindest eines der beiden Profilabschnitte, welche die Seitenbegrenzungen der Befestigungsnut bilden, ein Kraft- und/oder Formschlusses in einer Richtung senkrecht zur Profillängsrichtung von Nutgrund wegzeigend zwischen dem Isolierprofil und den Seitenbegrenzungen der Befestigungsnut hergestellt. Bevorzugterweise erfolgt das Verformen derart, dass danach auch ein Formschluss zwischen dem Isolierprofil und den Seitenbegrenzungen der Befestigungsnut in Profillängsrichtung vorliegt. Das Verformen erfolgt bevorzugterweise durch Anrollen.Then, when inserted in the fastening groove insulating profile by plastic deformation of at least one of the two profile sections, which form the side boundaries of the mounting groove, a force and / or positive connection in a direction perpendicular to the profile longitudinal direction of groove base pointing away between the insulating profile and the side boundaries of the mounting groove. Preferably, the deformation takes place in such a way that thereafter there is also a positive connection between the insulating profile and the lateral boundaries of the fastening groove in the profile longitudinal direction. The deformation is preferably carried out by rolling.

In einer bevorzugten Ausführungsform des Verfahrens wird von einem Metallprofil mit einer Befestigungsnut mit im Wesentlichen parallelen Seitenbegrenzungen ausgegangen. In diese Befestigungsnut wird ein Isolierprofil eingesetzt, wobei die in die Befestigungsnut eingesetzte Profilkontur des Isolierprofils eine Nut und/oder einen Hinterschnitt aufweist.In a preferred embodiment of the method is assumed by a metal profile with a mounting groove with substantially parallel side boundaries. In this fastening groove, an insulating profile is used, wherein the profile contour of the insulating profile inserted into the fastening groove has a groove and / or an undercut.

Sodann wird bei in der Befestigungsnut eingesetztem Isolierprofil zumindest einer der beiden Profilabschnitte, welche die Seitenbegrenzungen der Befestigungsnut bilden, derart plastisch verformt, dass er nach der Verformung mit einer Profilkontur in die Nut und/oder den Hinterschnitt in der Profilkontur des Isolierprofils eingreift. Hierdurch kann ein guter Formschluss zwischen dem Isolierprofil und den Seitenbegrenzungen der Befestigungsnut in einer Richtung senkrecht zur Profillängsrichtung von Nutgrund wegzeigend erreicht werden.Then, when used in the fastening groove Isolierprofil at least one of the two profile sections, which form the side boundaries of the mounting groove, plastically deformed so that it engages after deformation with a profile contour in the groove and / or the undercut in the profile contour of the insulating profile. In this way, a good fit between the insulating profile and the side boundaries of the mounting groove can be achieved pointing away in a direction perpendicular to the profile longitudinal direction of groove base.

Dabei ist es in einer Variante weiter bevorzugt, dass der zumindest eine Profilabschnitt derartig verformt wird, insbesondere durch Anrollen mittels Prägerollen, dass seine Profilkontur, welche in die Nut und/oder den Hinterschnitt in der Profilkontur des Isolierprofils eingreift, von einer Vielzahl identischer, in Profillängsrichtung mit einem insbesondere gleichmässigen Abstand zueinander angeordneter Prägungen gebildet wird. Hierdurch kann für den Fall, dass die Prägungen derartig ausgestaltet werden, dass sie Material des Isolierprofils verdrängen, auch ein Formschluss zwischen dem Metallprofil und dem Isolierprofil in Profillängsrichtung erreicht werden.It is further preferred in a variant that the at least one profile section is deformed in such a way, in particular by rolling by embossing rollers, that its profile contour, which engages in the groove and / or the undercut in the profile contour of the insulating profile, of a plurality identical, in Profile longitudinal direction is formed with a particular uniform spacing from each other arranged imprints. In this way, in the event that the embossments are configured such that they displace material of the insulating profile, a positive connection between the metal profile and the insulating profile in the profile longitudinal direction can be achieved.

Further preferred embodiments of the invention will become apparent from the dependent claims and from the following description with reference to FIGS. Showing:
  • Fig. 1 a cross section through a first inventive composite profile;
  • Fig. 2 a cross section through a second inventive composite profile;

Ein erstes Ausführungsbeispiel des erfindungsgemässen Verbundprofils ist im Querschnitt in Fig. 1 gezeigt. Wie zu erkennen ist, umfasst dass Verbundprofil ein oberes Metallprofil 2 und ein unteres Metallprofil 3, welche über ein einzelnes Isolierprofil 1 aus einem Kunststoffmaterial mit geringer Wärmeleitfähigkeit miteinander verbunden sind und dadurch thermisch weitestgehend voneinander entkoppelt sind. Die beiden Metallprofile 2, 3 sind durch Umformen aus einem Blechmaterial aus Stahl hergestellt.A first embodiment of the inventive composite profile is in cross section in Fig. 1 shown. As can be seen, the composite profile comprises an upper metal profile 2 and a lower metal profile 3, which are connected to each other via a single insulating profile 1 made of a plastic material with low thermal conductivity and are thermally largely decoupled from each other. The two metal profiles 2, 3 are made by forming from a sheet steel material.

Dabei ist in jedem der Metallprofile 2, 3 jeweils eine verdickte Profilkontur 4 des Isolierprofils 1 in einer vom jeweiligen Metallprofil 2, 3 gebildeten Befestigungsnut mit zwei sich gegenüberliegenden Seitenbegrenzungen 5 aufgenommen. Die Seitenbegrenzungen 5 der Befestigungsnuten werden jeweils von laschenartigen Profilabschnitten 6 gebildet, welche jeweils etwa in der Mitte der verdickten Profilkonturen 4 des Isolierprofils 1 mit einer Vielzahl identischer, in Profillängsrichtung mit einem gleichmässigen Abstand zueinander angeordneter Prägungen 11 in eine an der Profilkontur 4 gebildete Nut (siehe Positionsziffer 10 in Fig. 4) eingreifen. Zudem umgreifen die Profilabschnitte 6 mit ihren freien Enden 13 die verdickte Profilkontur 4 des Isolierprofils 1. Sie greifen also, mit anderen Worten ausgedrückt, mit ihren freien Enden 13 jeweils in einen durch eine Verjüngung des Isolierprofils 1 im Bereich des offenen Endes der jeweiligen Befestigungsnut gebildeten Hinterschnitt 12 ein.In each case, a thickened profile contour 4 of the insulating profile 1 is received in each of the metal profiles 2, 3 in a fastening groove formed by the respective metal profile 2, 3 with two opposite side boundaries 5. The lateral boundaries 5 of the fastening grooves are each formed by tab-like profile sections 6, which are each approximately in the middle of the thickened profile contours 4 of the insulating profile 1 with a plurality of identical, in the profile longitudinal direction with a uniform spacing arranged embossments 11 in a groove formed on the profile contour 4 (US Pat. see position 10 in Fig. 4 ) intervene. In addition, they grip, in other words, with their free ends 13 in each case in a formed by a taper of the insulating profile 1 in the region of the open end of the respective mounting groove with their free ends 13 thickened profile contour Undercut 12 a.

Dadurch, dass die laschenartigen Profilabschnitte 6 unter Druckvorspannung an den verdickten Profilkonturen 4 des Isolierprofils 1 anliegen und durch die Prägungen 11 bei deren Erzeugung Material in den Nuten 10 im Isolierprofil 1 verdrängt wurde, liegt zwischen dem Isolierprofil 1 und dem jeweiligen Metallprofil 2, 3 nicht nur ein Formschluss senkrecht zur Profillängsrichtung vor, sondern auch ein Kraftschluss sowie ein Formschluss in Profillängsrichtung.The fact that the tab-like profile sections 6 abut under pressure prestress on the thickened profile contours 4 of the insulating profile 1 and was displaced by the embossments 11 in their production material in the grooves 10 in the insulating profile 1, is not between the insulating profile 1 and the respective metal profile 2, 3 only a positive connection perpendicular to the profile longitudinal direction before, but also a positive connection and a positive connection in the profile longitudinal direction.

Beim unteren Metallprofil 3 sind die laschenartigen Profilabschnitte 6 direkt und auf kürzestem Weg über einen Steg 14 miteinander verbunden.When the lower metal section 3, the tab-like profile sections 6 are connected directly and by the shortest route via a web 14 together.

Beim oberen Metallprofil 2 hingegen, bei welchem es sich um ein erfindungsgemässes Metallprofil handelt, sind die laschenartigen Profilabschnitte 6, welche die Seitenbegrenzungen 5 der Befestigungsnut bilden, über einen Profilabschnitt 7 miteinander verbunden, in welchem die Profilkontur eine Profilschleife beschreibt, die einen Profilhohlraum 16 bildet. Profilabschnitte 8, 9 dieser Profilschleife grenzen in einem Bereich direkt angrenzend an den linken der beiden Profilabschnitte 6, welche die Seitenbegrenzungen 5 der Befestigungsnut bilden, flächig aneinander an und sind in diesem Bereich durch eine flächige und sich durchgehend in Profillängsrichtung erstreckende Lötfuge 15 stoffschlüssig miteinander verbunden.On the other hand, in the case of the upper metal profile 2, which is a metal profile according to the invention, the lug-like profile sections 6, which form the lateral boundaries 5 of the fastening groove, are interconnected via a profile section 7 in which the profile contour describes a profile loop which forms a profile cavity 16 , Profile sections 8, 9 of this profile loop border in a region directly adjacent to the left of the two profile sections 6, which form the side boundaries 5 of the mounting groove, flat against each other and are in this area by a flat and continuously extending in the profile longitudinal direction solder joint 15 materially connected to each other ,

Fig. 2 zeigt eine zweites Ausführungsbeispiel eines erfindungsgemässen Verbundprofils im Querschnitt, welches sich von dem in Fig. 1 gezeigten im Wesentlichen dadurch unterscheidet, dass die Profilschleife des Profilabschnitts 7 des erfindungsgemässen oberen Metallprofils 2 keinen Profilhohlraum bildet, sondern vollständig als Blechdoppelung ausgebildet ist, bei welcher die die Profilschleife bildenden Profilabschnitte über den gesamten Bereich der Profilschleife in Form von zwei flachen Blechlaschen 8, 9 flächig aneinander angrenzen bzw. aufeinanderliegen. Ein weiterer Unterschied besteht hier darin, dass diese Profilabschnitte 8, 9 nicht miteinander verlötet sind, sondern durch einzelne voneinander beabstandete Schweisspunkte 17, welche durch Widerstandsschweissen erzeugt wurden, im Bereich des zum offenen Ende der Profilschleife hin zeigenden Endes der Blechdoppelung, welches direkt angrenzend an den linken der beiden Profilabschnitte 6 ist, stoffschlüssig miteinander verbunden sind. Fig. 2 shows a second embodiment of an inventive composite profile in cross-section, which differs from the in Fig. 1 shown essentially differs in that the profile loop of the profile section 7 of the inventive upper metal profile 2 does not form a profile cavity, but is completely formed as a sheet metal doubling, in which the profile loop forming profile sections over the entire region of the profile loop in the form of two flat sheet metal tabs 8, 9 flat adjacent to each other or lie on each other. Another difference here is that these profile sections 8, 9 are not soldered together, but by individual spaced apart welding points 17, which were produced by resistance welding, in the region of the open end of the profile loop towards the end of the sheet double, which directly adjacent to the left of the two profile sections 6, are materially interconnected.

Fig. 3 zeigt eine drittes Ausführungsbeispiel eines erfindungsgemässen Verbundprofils im Querschnitt, welches sich von dem in Fig. 2 gezeigten im Wesentlichen dadurch unterscheidet, dass beim oberen erfindungsgemässen Metallprofil 2 die laschenartigen Profilabschnitte 6, welche die Seitenbegrenzungen 5 der Befestigungsnut bilden, über zwei spiegelbildliche Profilabschnitte 7, in welchen die Profilkontur jeweils gemäss Fig. 2 eine vollständig als Blechdoppelung ausgebildete Profilschleife beschreibt, miteinander verbunden sind. Ein weiterer Unterschied besteht darin, dass die jeweils die Profilschleifen bildenden Profilabschnitte 8, 9 nicht über einzelne Schweisspunkte miteinander verbunden sind, sondern stattdessen im gleichen Bereich jeweils mittels einer durch Laserschweissen erzeugten Schweissnaht 18. Fig. 3 shows a third embodiment of an inventive composite profile in cross-section, which differs from the in Fig. 2 shown essentially differs in that the upper inventive metal profile 2, the tab-like profile sections 6, which form the side boundaries 5 of the mounting groove, two mirror-image profile sections 7, in which the profile contour respectively Fig. 2 describes a completely formed as a sheet double profile loop, are connected together. Another difference is that the respective profile sections 8, 9 forming the profile loops are not connected to one another via individual welding points, but instead in the same area in each case by means of a welded seam 18 produced by laser welding.

Fig. 4 zeigt einen Querschnitt durch das Isolierprofil 4 aus den Figuren 1 bis 3 im Ausgangszustand, d.h. vor dem Zusammenfügen mit den Metallprofilen 2, 3 zum jeweiligen Verbundprofil. In dieser Darstellung sind die Nuten 10 in den verdickten Profilkonturen 4 des Isolierprofils 1 deutlich zu erkennen. Fig. 4 shows a cross section through the insulating profile 4 of the FIGS. 1 to 3 in the initial state, ie before joining with the metal profiles 2, 3 to the respective composite profile. In this illustration, the grooves 10 in the thickened profile contours 4 of the insulating profile 1 are clearly visible.

Die Figuren 5 und 6 zeigen Querschnitte durch das obere erfindungsgemässe Metallprofil 2 (Fig. 5) und das untere Metallprofil 3 (Fig. 6) des Verbundprofils aus Fig. 3 vor dem Zusammenfügen mit dem Isolierprofil zum entprechenden Verbundprofil.The FIGS. 5 and 6 show cross sections through the upper inventive metal profile 2 ( Fig. 5 ) and the lower metal profile 3 ( Fig. 6 ) of the composite profile Fig. 3 before joining with the insulating profile to entprechenden composite profile.

Wie aus diesen Darstellungen in Zusammenschau mit Fig. 7 hervorgeht, welche einen Querschnitt durch die Profile 1, 2, 3 aus den Figuren 4 bis 6 in einem zusammengesteckten Zustand direkt vor dem Zusammenfügen zu dem Verbundprofil gemäss Fig. 3 zeigt, bilden die Metallprofile 2, 3 im Ausgangszustand mit ihren laschenartigen Profilabschnitten 6 jeweils eine Befestigungsnut mit parallelen ebenen Seitenbegrenzungen 5, deren lichte Weite der Breite der jeweiligen darin aufzunehmenden verdickten Profilkontur 4 des Isolierprofils 1 entspricht und deren Tiefe derartig bemessen ist, dass die freien Enden der laschenartigen Profilabschnitte 6 geringfügig über diese Profilkontur 4 überstehen.As seen from these representations in synopsis with Fig. 7 which shows a cross section through the profiles 1, 2, 3 from the FIGS. 4 to 6 in a mated condition immediately prior to assembly to the composite profile according to Fig. 3 shows the metal profiles 2, 3 in the initial state with their tab-like profile sections 6 each have a mounting groove with parallel planar side boundaries 5, the inside width of the width of the respective absorbed therein thickened profile contour 4 of the insulating profile 1 and whose depth is dimensioned such that the free Ends of the Tab-like profile sections 6 slightly beyond this profile contour 4 survive.

Um ausgehend von dem in Fig. 7 gezeigten zusammengesteckten Zustand zu dem in Fig. 3 gezeigten fertigen Verbundprofil zu gelangen, werden die laschenartigen Profilabschnitte 6 der Metallprofile 2, 3 durch spezielle Andrückrollen derartig verformt, dass sie mit ihren freien Enden 13 jeweils die verdickte Profilkontur 4 des Isolierprofils 1 umgreifen und mit einer Vielzahl identischer, in Profillängsrichtung mit einem gleichmässigen Abstand zueinander angeordneter Prägungen 11 jeweils in die jeweilige Nut 10 in der Profilkontur 4 des Isolierprofils 1 eingreifen, unter Verdrängung von Material am Isolierprofil 1.To start from the in Fig. 7 shown mated state to the in Fig. 3 To reach shown finished composite profile, the tab-like profile sections 6 of the metal profiles 2, 3 are deformed by special pressure rollers such that they surround with their free ends 13 each of the thickened profile contour 4 of the insulating 1 and with a plurality of identical, in the profile longitudinal direction with a uniform distance mutually arranged embossments 11 each engage in the respective groove 10 in the profile contour 4 of the insulating profile 1, with displacement of material on the insulating profile. 1
