Description

Die Erfindung betrifft ein Verbundprofil mit den Merkmalen des Oberbegriffs des Patentanspruchs 1.The invention relates to a composite profile with the features the preamble of claim 1.

Aus der DE-OS 28 26 874 ist ein gattungsgemäßes Verbundprofil bekannt. Dort werden Bereiche der Nuten der Profilteile aus Metall mit Hilfe eines geeigneten Werkzeugs mechanisch in das Material der wärmeisolierenden Profilschiene eingedrückt. Der Grad dieser Einformungen und damit die erreichte Schubfestigkeit ist abhängig von der über das Werkzeug aufgebrachten Kraft sowie von der Härte des Materials der isolierenden Profilschiene.From DE-OS 28 26 874 is a generic Composite profile known. There are areas of the grooves of the Profile parts made of metal using a suitable tool mechanically in the material of the heat insulating Profile rail pressed in. The degree of this indentation and thus the shear strength achieved depends on the force applied by the tool and hardness of the material of the insulating profile rail.

Der Erfindung liegt die Aufgabe zugrunde, bei einem gattungsgemäßen Verbundprofil die Schubfestigkeit zwischen den Profilteilen aus Metall und der diese verbindenden wärmeisolierenden Profilschiene zu verbessern.The invention is based, with one generic composite profile the shear strength between the metal profile parts and the connecting parts to improve heat-insulating profile rails.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Vorsprünge aus geschmolzenem Material der Nutschenkel bestehen.This object is achieved in that the Protrusions consist of molten material of the groove legs.

Nach dem Zusammenfügen der Verbundprofilteile durch Anrollen des Nutenschenkels an den Fuß der Profilschiene erfolgt vorzugsweise an der Außenseite des Nutenschenkels ein Laserbeschuß, bei welchem das Metall punktförmig aufgeschmolzen wird und den Schmelzkegel bildet, der sich in das Kunststoffmaterial der Profilschiene einbrennt. Dadurch erfolgt ein Formschluß zwischen Profilteil und Profilschiene, so daß zur Trennung der Verbundprofilteile in Schubrichtung ein Abscheren der Schmelzkegel erfolgen müßte. Die Abstände der Anschmelzpunkte oder "Nietstellen" können in Abhängigkeit von der geforderten Schubfestigkeit ausgewählt werden.After joining the composite profile parts through Rolling the groove leg on the foot of the profile rail is preferably carried out on the outside of the groove leg a laser bombardment in which the metal is punctiform is melted and forms the melting cone that forms in burns in the plastic material of the profile rail. Thereby there is a positive connection between the profile part and Profile rail, so that to separate the composite profile parts in Shear direction should be sheared off the melting cone. The distances between the melting points or "riveting points" can depending on the required shear strength to be chosen.

In Weiterbildung der Erfindung ist im Fuß der Profilschiene ein in Profillängsrichtung verlaufender Metalldraht eingebettet und die Vorsprünge sind mit dem Metalldraht fest verschmolzen, so daß durch den Fuß der Profilschiene "Sperrstifte" ausgebildet werden.In a development of the invention is in the foot of the rail a metal wire running in the longitudinal direction of the profile embedded and the protrusions are fixed with the metal wire fused so that through the foot of the profile rail  "Lock pins" are formed.

Wenn die Energie des Lasers entsprechend ausgewählt wird, kann in Weiterbildung der Vorsprung den Metalldraht mit den beiden die Nut bildenden Nutschenkeln verbinden.If the energy of the laser is selected accordingly, can in training the lead the metal wire with the two connect the groove legs forming the groove.

Ausführungsbeispiele der Erfindung werden anhand der Zeich­ nung näher erläutert. Es zeigtEmbodiments of the invention are based on the drawing tion explained in more detail. It shows

Fig. 1 eine erste Ausführungsform eines Verbundprofils in einem Schnitt quer zur Verbundprofillängsrichtung, Fig. 1 shows a first embodiment of a composite profile in a section transverse to the longitudinal direction of the composite profile,

Fig. 2 eine abgewandelte Ausführungsform eines Verbund­ profils in einem Schnitt quer zur Verbundprofillängsrichtung und Fig. 2 shows a modified embodiment of a composite profile in a section transverse to the composite profile longitudinal direction and

Fig. 3 das Verbundprofil nach Fig. 2 im Schnitt längs der Linie III-III von Fig. 2. Fig. 3 shows the composite profile according to Fig. 2 in a section along the line III-III of Fig. 2.

Fig. 1 zeigt ein Teil eines Profilteils 10 aus Metall, das aus Aluminium oder einer geeigneten Aluminiumlegierung besteht. Das Profilteil 10 ist mit einer hinterschnittenen Nut 12 ausgebildet, die von Nutenschenkeln 14 und 16 gebildet wird. In dieser Nut 12 ist der Fuß 18 einer Profilschiene 20 aus Kunststoff eingeschoben. Der Nutschenkel 16 der Nut 12 ist vor dem Zusammenbau des Profilteils 10 und der Profilschiene 20 nach außen gebogen, so daß zwischen den Außenflächen des Fußes 18 der Profilschiene 20 und den Innenflächen der Nut 12 ein Zwischen­ raum verbleibt. Der Querschnitt der Nut 12 ist etwas größer als der Querschnitt des Fußes 18, damit beim Anrollen des Nutschenkels 16 die Profilschiene 20 sich ausrichten und die optimale Lage einnehmen kann, so daß die Abmessungen des Verbundprofils innerhalb der geforderten Toleranzen liegen. Fig. 1 shows a part of a profile part 10 made of metal, which consists of aluminum or a suitable aluminum alloy. The profile part 10 is formed with an undercut groove 12 , which is formed by groove legs 14 and 16 . The foot 18 of a plastic profile rail 20 is inserted into this groove 12 . The groove leg 16 of the groove 12 is bent outwards before the assembly of the profile part 10 and the profile rail 20 , so that an intermediate space remains between the outer surfaces of the foot 18 of the profile rail 20 and the inner surfaces of the groove 12 . The cross section of the groove 12 is slightly larger than the cross section of the foot 18 so that when the groove leg 16 rolls on, the profile rail 20 can align and assume the optimal position, so that the dimensions of the composite profile are within the required tolerances.

Nach dem Anrollen des Nutschenkels 16 wird dieser mit einem in Richtung des Pfeiles 22 gerichteten Laserstrahl bearbeitet. Dabei wird der Schenkel 16 punktförmig angeschmolzen. An der Außenseite des Schenkels 16 bildet sich eine Schmelzeintiefung 24 und an der Innenseite des Nutschenkels 16 ein Vorsprung 26 in Form eines Schmelzkegels, der infolge seiner Temperatur in den Fuß 18 der Profilschiene 20 ein­ schmilzt. Der Vorsprung 26 erbringt mit dem Fuß 18 der Profilschiene 20 eine Art "Vernietung". Die Bearbeitung mit dem Laserstrahl erfolgt in Längsrichtung des Verbundprofils in ausgewählten Abständen , so daß die Schubfestigkeit eingestellt werden kann.After the grooved leg 16 has rolled on, it is processed with a laser beam directed in the direction of the arrow 22 . The leg 16 is melted at a point. On the outside of the leg 16 a melt recess 24 is formed and on the inside of the groove leg 16 a projection 26 in the form of a melting cone, which melts due to its temperature in the foot 18 of the profile rail 20 . The projection 26 produces a kind of "riveting" with the foot 18 of the profile rail 20 . The processing with the laser beam takes place in the longitudinal direction of the composite profile at selected intervals, so that the shear strength can be adjusted.

Bei der in Fig. 2 gezeigten Ausführungsform ist mit einem Profiteil 30 aus Aluminium eine Profilschiene 32 aus Kunststoff verbunden. Im Fuß 34 der Profilschiene 32 ist, vorzugsweise bei der Extrusion der Profilschiene 32, ein Metalldraht 36 aus Aluminium eingelassen. Der Fuß 34 ist in einer Nut 38 in dem Profilteil 30 auf­ genommen, welche durch Nutschenkel 40 und 42 begrenzt wird. Nach dem Anrollen beispielsweise des Nutschenkels 42 an den Fuß 34 erfolgt ein Beschuß mittels eines Laserstrahls in Richtung des Pfeiles 44. Dabei wird der Nutschenkel 42 punktweise ange­ schmolzen und es bildet sich ein Vorsprung 46 in Form eines Schmelzkegels an der Innen­ seite des Nutschenkels 42 aus. Die Energie des Laserstrahls wurde derart abgestimmt, daß sich der Vorsprung 46 mit dem Metalldraht 36 aus Aluminium verbinden kann. Die Energie des Laserstrahls kann auch so gewählt werden, daß mittels eines Vorsprungs 48 eine Verbindung des Metalldrahtes 36 mit der Innenseite des Schenkels 40 erfolgt. Dadurch wird ein durch den Fuß 34 der Profil­ schiene 32 durchgehender "Sperrstift" geschaffen. Der Laserbeschuß erfolgt in ausgewählten Abständen punkt­ weise über die Länge des Verbundprofils.In the embodiment shown in FIG. 2, a profiled rail 32 made of plastic is connected to a professional part 30 made of aluminum. A metal wire 36 made of aluminum is embedded in the foot 34 of the profile rail 32 , preferably during the extrusion of the profile rail 32 . The foot 34 is received in a groove 38 in the profile part 30 , which is limited by groove legs 40 and 42 . After rolling up the nut leg 42 on the foot 34 , for example, a laser beam is fired in the direction of the arrow 44 . The groove leg 42 is melted at points and a projection 46 is formed in the form of a melting cone on the inside of the groove leg 42 . The energy of the laser beam was adjusted in such a way that the projection 46 can connect to the metal wire 36 made of aluminum. The energy of the laser beam can also be selected such that the metal wire 36 is connected to the inside of the leg 40 by means of a projection 48 . This creates a through the foot 34 of the profile rail 32 continuous "locking pin". The laser bombardment occurs at selected intervals point by point over the length of the composite profile.
