Description
Die Erfindung betrifft ein Extrusions- oder Koextrusionsprofil aus synthetischem Materia! mit einer in Extrusionsrichtung einen Kreisbogen beschreibenden Kontur für das flexible Abdecken, Abdichten, Verbinden und ähnliche Anwendungen eines veränderbaren, einen Kreisbogen beschreibenden Spaltes, wie er in mannigfaltiger Form im Fahrzeugbau, im Maschinenbau, im Geräte- und Apparatebau oder in der Möbelindustrie gegenwärtig ist.The invention relates to an extrusion or coextrusion profile made of synthetic material with a contour describing a circular arc in the direction of extrusion for the flexible covering, sealing, connecting and similar applications of a variable gap describing a circular arc, as is present in a variety of forms in vehicle construction, mechanical engineering, device and apparatus construction or in the furniture industry.
Aus der Erfindung DE 2951435 ist ein Koextrusionsprofil bekannt, das als in mindestens zwei sich in seinen mechanischen Eigenschaften unterscheidenden Materialien extrudiert ist, das quer zur Extrusionsrichtung dehn- oder stauchbar, z.B. auch faltbar ist, bekannt. Mittels dieses Profiles ist es möglich, Spalte veränderbaren Abstandes, so im Bereich „offen" bis „geschlossen", abzudecken bzw. abzudichten. In einer weiteren Erfindung wird vorgeschlagen, unter Anwendung eines Profiles gemäß DE 2951435, für die Lösung komplexer Aufgaben des Abdeckens, Abdichtens oder Verkleidens und Verbindens, sich des erfindungsgemäßen, modulationsfähigen Systemes von miteinander fügbaren Bauteilen zu bedienen. \ 'From the invention DE 2951435 a coextrusion profile is known which is extruded in at least two materials with different mechanical properties, which can be stretched or compressed transversely to the direction of extrusion, e.g. can also be folded. Using this profile it is possible to cover or seal gaps of variable distance, for example in the range "open" to "closed". In a further invention it is proposed to use the inventive, modulable system of components that can be joined together, using a profile according to DE 2951435, to solve complex tasks of covering, sealing or cladding and connecting. \ '
Den Stand der Technik repräsentierenden Lösungen für das Abdecken, Abdichten, Verbinden eines veränderbaren Spaltes, mittels bekannter, quer zur Extrusionsrichtung dehn- oder stauchbarer, Extrusionsprofile, ist eigen, dass ihrer Anwendung dann Grenzen gesetzt sind, so der abzudeckende Spalt nicht parallel oder einem Winkel ähnlich, sondern von kreisbogenähnlicher Kontur ist.The state of the art solutions for covering, sealing and connecting a variable gap by means of known extrusion profiles that can be stretched or compressed transversely to the extrusion direction have the characteristic that their application is limited if the gap to be covered is not parallel or similar to an angle, but has a contour similar to an arc of a circle.
Dem Trend in der Fahrzeugentwicklung entsprechend, stellvertretend die der Strassenfahrzeuge PKW, Van oder Wohnmobile sowie die der Schienenfahrzeuge, ist die Aufgabe zu lösen, stufenlos veränderbare bewegliche Spalte an Flächen, die eine kleinere Fläche umschließen und in ihrer Gesamtheit eine Wölbung, eine gewölbte Fläche verkörpern, technisch zuverlässig und ästhetisch einwändfrei abzudichten. , In line with the trend in vehicle development, representative of road vehicles such as cars, vans or mobile homes as well as rail vehicles, the task is to seal continuously variable movable gaps on surfaces that enclose a smaller area and, as a whole, embody a curvature, a curved surface, in a technically reliable and aesthetically flawless manner .
Konkret stellt sich diese Aufgabe z.B. an einem solchen Fahrzeugdach mit einem ausstellbaren, das Fahrzeugdach partiell öffnenden Deckel, das sich in Fahrzeugrichtung, betrachtet in Schnittdarsteliung, als Abschnitt eines Kreisbogens darstellt.In concrete terms, this task arises, for example, on a vehicle roof with a hinged cover that partially opens the vehicle roof and, viewed in section in the direction of the vehicle, appears as a section of a circular arc.
Für das Abdichten vorgenannter, eine Kurve beschreibender Spalte stehen bislang relativ weiche, in sich unbefriedigend formstabile Profile oder das segmentweise Fügen abgelängter Profilabschnitte, z.B. des aus dem DE 2951435 bekannten Profil, an.To date, relatively soft profiles with unsatisfactory shape stability or the segmental joining of cut-to-length profile sections, e.g. the profile known from DE 2951435, have been used to seal the aforementioned gaps that describe a curve.
Beiden Lösungen ist eigen, den Anforderungen an die Abdichtung, das Abdecken, das Verkleiden oder das Verbinden eines einen Kreisbogen beschreibenden Spaltes, werden sie sowohl von der Funktionalität als auch von der Ästhetik her, nur unbefriedigend gerecht.Both solutions have the characteristic that they do not adequately meet the requirements for sealing, covering, cladding or connecting a gap that describes a circular arc, both in terms of functionality and aesthetics.
Die Aufgabe der Erfindung besteht daher darin, gattungsgemäße Profile und Systemlösungen dahingehend zu verbessern bzw. weiter zu entwickeln, dass es mittels ihrer Anwendung möglich ist, außer einen in der Spaltbreite stufenlos veränderbaren Spalt auch dann sich und ästhetisch abzudichten, so diesem Spalt zudem eine kreisbogenähnliche Kontur zu eigen ist, „' _ .The object of the invention is therefore to improve or further develop generic profiles and system solutions in such a way that by means of their application it is possible not only to seal a gap whose width can be continuously varied but also to seal it aesthetically if this gap also has a contour similar to an arc of a circle, “' _ .
Bei einem bzw. an einem Extrusions- oder Koextrusionsprofil aus synthetischem Material nach dem Oberbegriff des Anspruches 1 wird diese Aufgabe erfindungsgemäß durch die in dem Anspruch 1 angegebenen Kennzeichnenden Merkmale gelöst. Ih den nachfolgenden Ansprüchen werden vorteilhafte Ausführungen und Ausgestaltungen des Erfindüngsstandes, ohne dass die vollständige Spannbreite der Erfindung erfasst ist, angegeben.In an extrusion or coextrusion profile made of synthetic material according to the preamble of claim 1, this object is achieved according to the invention by the characterizing features specified in claim 1. The following claims specify advantageous embodiments and configurations of the state of the art in the invention, without covering the full scope of the invention.
Die Ausführungen und Ausgestaltungen des Erfindungsgegenstandes entsprechend den in den Unteransprüchen angegebenen Merkmalen führen zur Ausbildung eines Extrusions-oder Koextrusionsprofiles, dessen kreisbogenähnliche Kontur sowohl durch dauerhafte plastische Deformierung einer metallischen Armierung als auch einer nichtmetallischen,.einem reckbaren mechanisch festeren Kunststoff z.B. oder der Kombination beider, ausgebildet bzw. ausbildbar ist. Für die Ausbildung der Dehn- bzw. Stauchbarkeit des Extrusios- oder Koextrusionsprofiles, quer zu dessen Extrusionsrichtung, lehrt die Erfindung, diesen Profilabschnitt z.B. definiert faltbar auszubilden oder auch eine folieänliche, mit gummielastischen Eigenschaften versehene, in sich weniger formstabile Ausführung vorzusehen. , ' ·&ngr; The designs and embodiments of the subject matter of the invention according to the features specified in the subclaims lead to the formation of an extrusion or coextrusion profile, the contour of which is similar to an arc of a circle and is formed or can be formed by permanent plastic deformation of a metallic reinforcement as well as a non-metallic one, a stretchable, mechanically stronger plastic, for example, or a combination of both. To form the stretchability or compressibility of the extrusion or coextrusion profile, transverse to its extrusion direction, the invention teaches that this profile section can be formed in a defined foldable manner, for example, or that a film-like design with rubber-elastic properties and which is less dimensionally stable in itself can be provided. , ' · &ngr;
• · 1 ·· 1 ·
Auch eine Kombination beider ist dann herstellbar, so für eine solche synthetische Werkstoffe unterschiedlicher mechanischer Festigkeiten koextrudiert werden.A combination of both can also be produced by co-extruding synthetic materials with different mechanical strengths.
Die Vielfalt der Optionen für die Ausbildung bzw. Anordnung der kreisbogenähnlichen Kontur im besonderen der gemäß Anspruch 7, eröffnen dem Extrusions- oder Köextrusions Anwendungsmöglichkeiten, die sich nicht auf den Fahrzeug- den Maschinenbau, die Möbel- oder die Bauindustrie beschränken.The variety of options for the formation or arrangement of the circular arc-like contour, in particular that according to claim 7, open up application possibilities for the extrusion or co-extrusion which are not limited to the automotive, mechanical engineering, furniture or construction industries.
