Abstract

Profilés composites composés d'une partie métallique (6) reliée à une partie non métallique (8) ainsi que de deux parties (7) intermédiaires calorifuges situées entre celles-ci. La partie calorifuge est fermement reliée à la partie non métallique (8) par liaison de forme et par la pression. Cette pression assure un effet de serrage ferme lorsque les parties à liaison de forme (6, 7) sont rapprochées (fig.2) perpendiculairement à la direction longitudinale de celle-ci, grâce à la déformation plastique d'arêtes ou de protubérances (6a) situées dans des dégagements correspondants (7b), sur la partie calorifuge (7), avec des régions de contact limité (7c, C) entre les parties (6, 7). Par conséquent, à certaines valeurs de charge, des déplacements longitudinaux et/ou transversaux limités sont possibles dans le sens longitudinal et/ou le sens transversal (variations dues à la dilatation thermique).Composite profiles composed of a metallic part (6) connected to a non-metallic part (8) as well as two heat-insulating intermediate parts (7) located between them. The heat insulating part is firmly connected to the non-metallic part (8) by form bonding and pressure. This pressure ensures a firm clamping effect when the form-fitting parts (6, 7) are brought together (fig.2) perpendicularly to the longitudinal direction thereof, thanks to the plastic deformation of edges or protuberances (6a ) located in corresponding recesses (7b), on the heat-insulating part (7), with limited contact regions (7c, C) between the parts (6, 7). Therefore, at certain load values, limited longitudinal and/or transverse displacements are possible in the longitudinal and/or transverse direction (variations due to thermal expansion).

VERBUNDPROFILCOMPOSITE PROFILE
Im Sektor der Profilherstellung für Fenster und Türen ist seit geraumer Zeit die Herstellung von Verbundprofilen zwecks Zuweisung unterschiedlicher statischer, ästhetischer und/oder Wartungsprobleme (DE-PS-801 468) , beziehungswei- se zwecks Herabsetzung der Wärmeübertragung zwischen Außen - und Innenteil des Fensterprofils (DE-AS 109 1735; AT-PS - 281384) , bekannt. All die verschiedenen Zusammenbausysteme für Verbundprofile , einschließlich jene für Verbundpro ile aus Teilen gleichartigen Werkstoffs, weisen den Nachteil auf, daß sie sich wegen der unterschiedlichen Wärmeausdeh¬ nung und/oder , im Falle von Metall-Holz Profilen, wegen Maßschwankungen bei Feuchtigkeitsaufnahme, verformen . Es ist bekannt, daß diese Mißstände Dichtungsschwierigkei¬ ten zwischen Stock und Flügel sowie Risse an den Rahmenek- ken mit sich bringen. Weiters ist es bekannt diese Verfor¬ mungen durch ein gegenseitiges Gleiten der Teile in Längs¬ richtung zu beschränken.For some time now, the manufacture of composite profiles for the assignment of different static, aesthetic and / or maintenance problems (DE-PS-801 468), or for the purpose of reducing the heat transfer between the outer and inner part of the window profile ( DE-AS 109 1735; AT-PS - 281384), known. All the different assembly systems for composite profiles, including those for composite profiles made of parts of the same material, have the disadvantage that they deform due to the different thermal expansion and / or, in the case of metal-wood profiles, due to dimensional fluctuations in moisture absorption. It is known that these defects result in sealing difficulties between the cane and sash and cracks in the frame corners. Furthermore, it is known to limit these deformations by mutual sliding of the parts in the longitudinal direction.
Wenn auch diese letzten Vorkehrungen nicht das Problem der Verformung an den Rahmenecken montierter Fenster und Türen losen an welchen die Längsbewegungen Drehmomente an den im rechten Winkel verbundenen Profilen hervorrufen; bringen diese den Vorteil zufriedenstellend geradlinige Verbundpro¬ file, mindestens währen deren Verarbeitung zu haben, was ei¬ ne genaue und saubere Bearbeitung erleichtert. Eine weitere Schwierigkeit in der Herstellung von Verbund¬ profilen besteht in der Anbringung und Befestigung des Ver- 1 bindungselements (Wärmeisolation) , welches möglichst Kälte¬ brücken zwischen den Teilen vermeiden soll, ein optimaler Isolator sein soll, sowie die Parallelität der Teile und die Maßgenauigkeit des Profils garantieren soll.Even if these last precautions do not solve the problem of deformation of windows and doors mounted on the corners of the frame, at which the longitudinal movements cause torques on the profiles connected at right angles; these have the advantage of having satisfactorily linear composite profiles, at least during their processing, which facilitates precise and clean processing. Another difficulty in the production of composite profiles is the attachment and fastening of the fastening 1 binding element (thermal insulation), which should avoid cold bridges between the parts, should be an optimal insulator, and should guarantee the parallelism of the parts and the dimensional accuracy of the profile.
5 Als Verbindungselement ist die Anwendung von Schaumstoffen bekannt deren Einbringung mittels Vorrichtungen und Vorkeh¬ rungen geschieht, welche bis zum Aushärten des Schaumstoffes die Freiräume zwischen den zu verbindenden Teilen abdecken (AT-PS 281 384; AT-PS 322 179). Dies wird auch durch be -5 As the connecting element, the use of foams is known, the introduction of which takes place by means of devices and precautions which cover the free spaces between the parts to be joined until the foam hardens (AT-PS 281 384; AT-PS 322 179). This is also supported by

Weiters ist das Einschie¬ ben von Kunststoffleisten oder-profilen bekannt, welche form schlüssig in die zu verbindenden Teile eingreifen (DE-OS10 limited contact zones between the wooden and aluminum parts to be joined, which often leads to a blackening of the wood.

Auch ist es bekannt die Verbindung der Teile dadurch zu er¬ reichen, daß diese durch Rollen oder andere Vorrichtungen von außen so bearbeitet werden, daß Teile des Metallprofiles15 25 16 753), these strips are locked in place by elastic deformation in the grooves during insertion. It is also known to achieve the connection of the parts by machining them from the outside by means of rollers or other devices such that parts of the metal profile

Die Erfindung stellt sich die Aufgabe ein Verbundprofil für Tür.en und Fenster zu schaffen, welches ein thermisch isolie rendes, leicht anzubringendes Verbindungsteil aufweist, das-0 be deformed without, however, providing for limited sliding between the parts in the longitudinal and / or transverse direction. The invention has for its object to provide a composite profile for Tür.en and windows, which has a thermally isolating, easy-to-install connector that
15 ein begrenztes Gleiten zwischen den Teilen in Längs - und/ oder Querrichtung ermöglicht, innere Spannungen ausschließt und in der Lage ist Aufgaben zu übernehmen, welche bis jetzt den zu verbindenden Teilen zugewiesen werden waren . Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß auf15 allows limited sliding between the parts in the longitudinal and / or transverse direction, excludes internal tensions and is able to take on tasks which were previously assigned to the parts to be connected. This object is achieved in that
--0 mindestens einer Seite der Verbindung zwischen Profil und Verbindungselement eine formschlüssige Verbindung vorgesehen ist, welche infolge plastischer Verformung von, am Metall - profil vorgesehenen Stegen oder Klammervorsprüngen, wirksam wird . Diese Verformung wird durch zwangsläufige Annäherung--0 At least one side of the connection between the profile and the connecting element is provided with a positive connection, which becomes effective as a result of plastic deformation of webs or clip projections provided on the metal profile. This deformation is due to inevitable approximation
35 zwischen dem Metallprofil und dem Verbindungselement in Quer_ richtung erreicht, wobei as Verbindungselement selbst als Verformungswerkzeug dient.35 between the metal profile and the connecting element in Quer_ direction reached, as the connecting element itself serves as a deformation tool.
Um dies zu verwirklichen weist das Verbindungselement mindestens eine Längsrille auf in welche Zungen oder Ste- ge des eingeschobenen Metallprofils ragen. Obige Stege weisen in einem abgewinkelten Bereich eine Querschnitts¬ verminderung auf um eine vorbestimmte Verformungsstelle zu erhalten; die Verformung wird durch Anpressen des Ver¬ bindungselements gegen das Metallprofil in Querrichtung erreicht. Erfindungsgemäß ist die Form der Stege so, daß durch die gegenseitige Wirkung der Rillenoberflächen an jenen der Stege ein Festklammern des Metallprofiles, am Verbindungselement bewirkt wird wodurch, sei es in Längs¬ ais auch in Querrichtung eine, bis zu begrenzter Belastung wirksame, Arretierung zwischen den Elementen wirksam wird , wobei in Querrichtung ein Spiel zwischen den Teilen vorge¬ sehen ist. Nachdem die Kontaktbereiche zwischen den ver¬ bundenen Teilen begrenzt sind ermöglicht die durch Reibung garantierte Arretierung, sobald die Belastungen in Längs- und in Querrichtung bestimmte Werte überschreiten, ein gegenseitiges Gleiten in diese Richtungen. Erfindungsgemäß kann das Verbindungselement z.B. aus ex - trüdierte PVC sein, es kann innere Hohlräume aufweisen welche gegebenenfalls ausgeschäumt werden können. Die Ober; flächen des Verbindungselementes, welche auf die Klammer - Stege wirken,können erfindungsgemäß eine Verkleidung tra¬ gen oder bearbeitet werden so daß die erforderliche Festig; keit erreicht wird. Gemäß einer Weiterentwicklung können die Rillen in welche die Stege eingreifen auch aus U - förmigen Profilen, z.B. aus Metall, bestehen welche an einem Schaumstoffprofil vorgesehen sind, welches weiters Stege, Rillen oder Sitze im allgemeinen Sinn aufweisen kann um andere das Verbundprofil bildende Teile daran montieren und befestigen zu können . Erfindungsgemäß kann das zweite Profil, welches vom selben Verbindungs - - 4 -To achieve this, the connecting element has at least one longitudinal groove into which tongues or webs of the inserted metal profile protrude. The above webs have a reduced cross-section in an angled area in order to obtain a predetermined deformation point; the deformation is achieved by pressing the connecting element against the metal profile in the transverse direction. According to the invention, the shape of the webs is such that, due to the mutual action of the groove surfaces on those of the webs, the metal profile is clamped onto the connecting element, whereby, in the longitudinal direction as well as in the transverse direction, an up to limited load locking between the Elements is effective, with a play between the parts is provided in the transverse direction. Since the contact areas between the connected parts are limited, the locking guaranteed by friction enables mutual sliding in these directions as soon as the loads in the longitudinal and transverse directions exceed certain values. According to the invention, the connecting element can be made of extruded PVC, for example, it can have internal cavities which can optionally be foamed. The waiter; surfaces of the connecting element, which act on the clip webs, can be covered or machined according to the invention so that the required strength; speed is achieved. According to a further development, the grooves in which the webs engage can also consist of U-shaped profiles, for example made of metal, which are provided on a foam profile, which can also have webs, grooves or seats in the general sense in order to mount other parts forming the composite profile thereon and to be able to attach. According to the invention, the second profile, which has the same connection - 4 -

Der Grad der Festklammerung kann unter Berücksichti¬ gung der elastischen Verformung der Klammer-Organe.welche der plastischen Verformung vorausgeht, beeinflußt werden;The degree of clamping can be influenced by taking into account the elastic deformation of the clamp organs, which precedes the plastic deformation;

Zwischen diese Stege 6c wird in Längsrichtung das Verbin - dungselement 7 aus Isoliermaterial eingeschoben, wobei die Rillen 7b der Lage der Klammerenden 6a entsprechen und die mit breiter Rille 7d und Vorsprüngen 7c an den Seiten versehene Auflage gegen die Fläche 6d gerichtet ist, von welcher die Stege 6c abstehen . Während einer zwangsläufig gen Annäherung dieser Teile in Querrichtung drückt die Fläche A des Elementes 7 gegen die Rundung B des Klammer- endes<6a wodurch, wegen der Querschnittsverminderung 6b , dieses soweit verbogen wird bis der Bereich C auf die Fläche D der Rille drückt, wobei die Vorsprünge 7c des Ver_ bindungselementes 7 an die Fläche 6d des Metallprofils gedrückt werden. Dabei wird jedoch in Querrichtung zu den verbundenen Teilen durch ein Spiel ein eventuelles be - grenztes Gleiten in diese Richtung gesichert . Während dieser Fase bleibender Verformung der Stege 6c mit den Klammerenden 6a kann eine begrenzte elastische Verformung von Bereichen des Verbindungselementes 7, wel- ehe sich zwischen den Klammerenden 6a und der Auflageflä¬ che 6d befinden, vorgesehen sein um so eine eventuelle e- lastische Rückstellung der Klammerenden 6a zu kompensie_ ren, Diese elastische Verformung kann von der Formgebung und der Anordnung der Vorsprünge 7c sowie der Rille 7d abhängig gemacht werden.Clamp ends 6a and a reduction in cross section 6b. The connecting element 7 made of insulating material is inserted in the longitudinal direction between these webs 6c, the grooves 7b corresponding to the position of the clip ends 6a and the support provided with a wide groove 7d and projections 7c on the sides directed against the surface 6d, of which the Protruding webs 6c.
