Description

Die vorliegende Erfindung betrifft ein Abstandhalterprofil aus einem elastisch-plastisch verformbaren, schlecht wärmeleitenden Material für einen Abstandhaherrahmen, der im Randbereich von mindestens zwei voneinander beabstandeten Scheiben, insbesondere transparenten Scheiben für Isolierscheibeneinheiten, unter Bildung eines Scheibenzwischenraumes anzubringen ist, wobei das Abstandhalterprofil eine Kammer umfaßt, die in ihren Wänden ein sich in Längsrichtung des Profils erstreckendes plastisch verformbares Verstärkungselement aufweist.The present invention relates to a spacer profile made of an elastically-plastically deformable, poorly heat-conducting material for a spacer frame in the edge area of at least two spaced apart disks, in particular transparent ones Washers for insulating washer units, to form a space between the washers is, wherein the spacer profile comprises a chamber which in its walls a plastically deformable reinforcing element extending in the longitudinal direction of the profile having.

Elastisch-plastisch verformbare Materialien meint im Rahmen der Erfindung solche Materialien, bei denen nach dem Biegeprozeß elastische Rückstellkräfte wirksam sind, wie es typischerweise bei Kunststoffen der Fall ist, wobei ein Teil der Biegung über eine plastische, nicht reversible Verformung erfolgt.Within the scope of the invention, elastically-plastically deformable materials mean such materials in which elastic restoring forces are effective after the bending process, as is typically the case is the case with plastics, whereby part of the bend is plastic, not reversible deformation occurs.

Plastisch verformbare Materialien umfaßt solche Materialien, bei denen nach der Verformung praktisch keine elastischen Rückstellkräfte wirken, wie es typischerweise beim Biegen von Metallen über die Streckgrenze hinaus der Fall ist.Plastically deformable materials include those materials after which the deformation practically no elastic restoring forces act, as is typical when bending Metals beyond the yield point is the case.

Unter schlecht wärmeleitenden oder wärmeisolierenden Materialien sollen solche Materialien verstanden werden, die gegenüber Metallen eine deutlich, das heißt mindestens um einen Faktor 10, geringere Wärmeleitfähigkeit zeigen. Die Wärmeleitwerte liegen typischerweise in der Größenordnung λ ≈ 5 W/ (m·K) und darunter, bevorzugt sind sie kleiner als 1 W/(m·K) und weiter bevorzugt kleiner als 0, 3 W/ (m·K). Such materials should be among poorly heat-conducting or heat-insulating materials are understood to be clear compared to metals, i.e. at least by one Factor 10, show lower thermal conductivity. The thermal conductivity values are typically in of the order of magnitude λ ≈ 5 W / (m · K) and below, preferably they are less than 1 W / (m · K) and more preferably less than 0.3 W / (m · K).

Die Scheiben der Isolierscheibeneinheit sind im Rahmen der Erfindung normalerweise Glasscheiben aus anorganischem oder organischem Glas, ohne daß die Erfindung allerdings hierauf beschränkt wäre. Die Scheiben können beschichtet oder auf andere Weise veredelt sein, um der Isolierscheibeneinheit besondere Funktionen, wie erhöhte Wärmedämmung oder Schalldämmung, zu verleihen.Within the scope of the invention, the panes of the insulating pane unit are normally glass panes made of inorganic or organic glass, but without the invention thereon would be limited. The panes can be coated or otherwise refined, around the insulating pane unit special functions such as increased thermal insulation or Soundproofing.

Abstandhalterrahmen haben als wichtigste Aufgabe, Scheiben einer Scheibeneinheit auf Abstand zu halten, die mechanische Festigkeit der Einheit zu gewährleisten und den Scheibenzwischenraum vor äußeren Einflüssen zu schützen. Vor allem bei Isolierscheibeneinheiten mit hoher Wärmedämmung ist festzustellen, daß die Wärmeübertragungscharakteristik des Randverbundes und damit des Abstandhalterprofils, aus dem der Abstandhalterrahmen hergestellt ist, besonderer Beachtung bedarf. Eine Verschlechterung der Wärmedämmung einer hoch wärmedämmend ausgelegten Isolierscheibeneinheit im Randbereich insbesondere durch übliche metallische Abstandhalter ist mehrfach nachgewiesen worden.The most important task of spacer frames is to keep windows of a window unit at a distance to maintain the mechanical strength of the unit and the space between the panes to protect against external influences. Especially with insulating washer units with high thermal insulation, it should be noted that the heat transfer characteristics of the edge bond and thus the spacer profile from which the spacer frame is made special attention is required. A deterioration in thermal insulation high Insulating pane unit designed for thermal insulation in the edge area, in particular by conventional metallic spacers have been proven several times.

Deshalb werden seit längerer Zeit neben metallischen Abstandhalterprofilen auch Abstandhalterprofile aus Kunststoff verwendet, um die geringe Wärmeleitfähigkeit dieser Materialien auszunutzen. Allerdings weisen derartige Materialien in der Regel eine im Vergleich zu Metallen geringe Diffusionsdichtigkeit auf. Da aber verhindert werden muß, daß in der Umgebung vorhandene Luftfeuchtigkeit in den Scheibenzwischenraum eindringt und auch ein Entweichen von Füllgasen, wie beispielsweise Argon, Krypton, Xenon und Schwefelhexafluorid, mit denen der Scheibenzwischenraum gefüllt ist, in minimalen Grenzen gehalten werden muß, sind bei der Verwendung von Profilen aus Kunststoff in der Regel besondere Maßnahmen erforderlich. Aus diesem Grunde ist z. B. in der DE-A- 33 02 659 vorgeschlagen, ein Abstandhalterprofil mit einer Dampfsperre zu versehen, indem auf das Kunststoffprofil eine Meiallfolie oder eine metallisierte Kunststoff-Folie aufgebracht wird.Therefore, in addition to metallic spacer profiles, spacer profiles have also been used for a long time Made of plastic used for the low thermal conductivity of these materials exploit. However, such materials usually have one compared to metals low diffusion tightness. But since it must be prevented that in the area existing humidity penetrates into the space between the panes and also escapes filling gases such as argon, krypton, xenon and sulfur hexafluoride, with which the space between the panes is filled must be kept within minimal limits, are usually special measures when using profiles made of plastic required. For this reason z. B. proposed in DE-A-33 02 659, a spacer profile to be provided with a vapor barrier by placing a Metal foil or a metallized plastic foil is applied.

Kunststoffprofile haben weiterhin den Nachteil, daß sie sich nur unter hohem Aufwand oder gar nicht zur Herstellung einstückiger Abstandhalterrahmen biegen lassen. Im allgemeinen werden daher Kunststoffprofile zu geraden Stangen in den den Abmessungen der jeweiligen Scheibeneinheit entsprechenden Maßen geschnitten und durch mehrere Eckverbindung miteinander zu einem Abstandhalterraum verbunden.Plastic profiles also have the disadvantage that they are only with great effort or do not bend at all to produce one-piece spacer frames. In general are therefore plastic profiles to straight rods in the dimensions of each Disc unit of appropriate dimensions cut and connected to each other by several corner connections connected to a spacer room.

Die DE-U-93 03 795, die für die Formulierung des Oberbegriffs des Anspruches 1 herangezogen wurde, offenbart sich in Längsrichtung des Profils erstreckende Verstärkungskörper, die ausschließlich in der dem Schreibenzwischenraum zugewandten Innenwand des Abstandhalterprofils eingebettet sind. Dadurch sollen sie die Stabilität der dem Scheibenzwischenraum zugewandten Innenwand, die durch UV-Einstrahlung und Wärmeausdehnung gefährdet ist, unterstützen. Das Biegeverhalten des vorbekannten Profils ist in der Druckschrift nicht angesprochen.DE-U-93 03 795 used for the formulation of the preamble of claim 1 reinforcement bodies extending in the longitudinal direction of the profile, the only in the inner wall of the spacer profile facing the space between the letters are embedded. This is supposed to ensure the stability of the space between the panes facing inner wall, which is endangered by UV radiation and thermal expansion is support. The bending behavior of the previously known profile is not in the publication addressed.

DE-U-92 14 799 und GB-A-2 162 228 offenbaren Abstandhalterprofile der eingangs genannten Art mit einem einzigen, sich von dem einen äußeren Eckbereich des Profils über dessen Außenwand in den anderen äußeren Eckbereich erstreckenden Verstärkungselement, das die Herstellung eines einstückigen Abstandhalterrahmens durch Biegen offensichtlich nicht zuläßt.DE-U-92 14 799 and GB-A-2 162 228 disclose spacer profiles of the aforementioned Kind with a single, from the one outer corner area of the profile over the Outer wall in the other outer corner area extending reinforcing element, which Manufacturing a one-piece spacer frame by bending obviously does not allow.

Es ist die Aufgabe der vorliegenden Erfindung, ein im großen Maßstab kostengünstig produzierbares wärmeisolierendes Abstandhalterprofil zur Verfügung zu stellen, aus dem einfach ein einstückiger Abstandhalterrahmen herstellbar sein soll. Das Profil soll insbesondere mit üblichen, allenfalls geringfügig modifizierten konventionellen Biegeanlagen kaltbiegbar sein, also mit allenfalls geringer Erwärmung so biegbar sein, daß störende Verformungen nicht auftreten.It is the object of the present invention to be inexpensive on a large scale to provide producible heat-insulating spacer profile from which a one-piece spacer frame should be easy to manufacture. The profile should especially with conventional, if necessary slightly modified, conventional bending systems be cold bendable, that is to say bendable with little warming at most, so that annoying Deformation does not occur.

Diese Aufgabe wird durch ein Abstandhalterprofil mit den Merkmalen des Patentanspruches 1 gelöst. Erfindungsgemäß ist vorgesehen, daß die Verstärkungselemente nur in den Seitenwänden und/oder den Eckbereichen des Profils vorgesehen sind.This object is achieved by a spacer profile with the features of patent claim 1 solved. According to the invention it is provided that the reinforcing elements only in the side walls and / or the corner areas of the profile are provided.

Da bei einem erfindungsgemäßen Abstandhalterprofil die Verstärkungselemente nur im Bereich der aus schlecht wärmeleitenden Material bestehenden Seitenwände des Abstandhalterprofils angeordnet sind und somit durch diese kein direkter thermischer Kontakt zwischen den Scheiben hergestellt wird, wird die Wärmeleitung von einer Scheibe zur anderen durch das Abstandhalterprofil durch die Verstärkungselemente nur in äußerst geringem Maße beeinflußt. Durch ihre plastische Verformbarkeit sowie die Anordnung im Bereich der Seitenwände des Profils tragen sie andererseits entscheidend zur Erfüllung der der Erfindung zugrundeliegenden Aufgabe bei. Since with a spacer profile according to the invention the reinforcing elements only in the area the side walls of the spacer profile consisting of poorly heat-conducting material are arranged and thus no direct thermal contact between the Disks is manufactured, the heat conduction from one disk to another through the Spacer profile through the reinforcement elements only to an extremely small extent affected. Due to their plastic deformability and the arrangement in the area of the side walls of the profile, on the other hand, they are crucial for fulfilling the invention underlying task at.

Durch die erfindungsgemäße Anordnung der Verstärkungselemente wird erreicht, daß bei der Auswahl des den Haupt-Volumenanteil des Profils ausmachenden elastisch-plastisch verformbaren, schlecht wärmeleitenden Materials dessen plastische Verformbarkeit nicht im Vordergrund steht, sondern auch nahezu vollkommen elastische Materialien verwendet werden können, wenn diese hinsichtlich der Wärmeisolation Vorteile bieten. Auf der anderen Seite können die Verstärkungselemente gezielt im Hinblick auf ihre plastische Verformbarkeit und ihre Eigenschaften während des Biegeprozesses ausgewählt werden, ohne daß ihre Abmessungen oder ihr Material im Hinblick auf die Höhe ihrer Wärmeleitfähigkeit wesentlichen Einschränkungen unterworfen sind.The inventive arrangement of the reinforcing elements ensures that the Selection of the elastic-plastically deformable, which forms the main volume portion of the profile, poorly heat-conducting material whose plastic deformability is not in the The focus is on the use of almost completely elastic materials can, if they offer advantages in terms of thermal insulation. On the other The reinforcing elements can be targeted with regard to their plastic deformability and their properties are selected during the bending process without losing their dimensions or their material with regard to the level of their thermal conductivity Are subject to restrictions.

Für den Biegeprozeß sind marktübliche Biegeanlagen ohne nennenswerte Modifikationen geeignet.For the bending process, customary bending systems are without any noteworthy modifications suitable.

Das erfindungsgemäße Profil ist als Hohlkammerprofil gestaltet, wobei die Kammer im Normalfall mit hygroskopischern Material gefüllt wird und wobei wasserdampfdurchlässige Bereiche, z.B. Perforationen, in der dem Scheibenzwischenraum zugewandten Innenwand der Kammer einen Dampf- oder Feuchtigkeitsaustausch zwischen dem Scheibenzwischenraum und der Kammer ermöglichen. Dadurch wird der Feuchtigkeitsgehalt in dem Scheibenzwischenraum niedrig gehalten, um eine Kondensation bei niedrigen Temperaturen zu vermeiden. Alternativ kann das Abstandhalterprofil auch einen zum Scheibenzwischenraurn hin offenen U-förmigen Querschnitt aufweisen, wenn dafür gesorgt wird, daß das Trockenmittel fest in der Kammer verankert ist, z.B. über Adhäsion. The profile according to the invention is designed as a hollow chamber profile, the chamber in the normal case is filled with hygroscopic material and with water vapor permeable areas, e.g. Perforations in the inner wall facing the space between the panes Chamber a steam or moisture exchange between the space between the panes and enable the chamber. As a result, the moisture content in the space between the panes kept low to avoid condensation at low temperatures. As an alternative, the spacer profile can also face the space between the panes have an open U-shaped cross-section if care is taken to ensure that the desiccant is firmly anchored in the chamber, e.g. about adhesion.

Der Querschnitt der Verstärkungselemente kann mannigfaltig ausgebildet werden. So können diese Elemente z. B. als Drähte ausgebildet sein, was eine einfache und damit kostengünstige Herstellung ermöglicht.The cross section of the reinforcing elements can be designed in a variety of ways. So can these elements z. B. be formed as wires, which is a simple and therefore inexpensive Manufacturing enables.

Ferner können die Verstärkungselemente auch als Flach- oder Winkelprofile ausgebildet sein. Dadurch wird eine besonders hohe Formstabilität, besonders in den Querschnitts-Eckbereichen, des Abstandhalterprofils gewährleistet. Es ist auch eine Kombination von Drähten und Flach- oder Winkelprofilen in einem Abstandhalterprofil möglich.Furthermore, the reinforcing elements can also be designed as flat or angle profiles. This ensures particularly high dimensional stability, especially in the cross-sectional corner areas, of the spacer profile guaranteed. It is also a combination of wires and Flat or angle profiles possible in a spacer profile.

Die Verstärkungselemente bestehen im allgemeinen aus Metall oder aus einer Metall-Legierung, bevorzugt aus Aluminium oder aus einer Aluminiumlegierung. Dadurch wird eine besonders hohe plastische Verformbarkeit des Abstandhalterprofils und ein besonders geringes Rückfedern nach dem Biegen erreichtThe reinforcing elements generally consist of metal or a metal alloy, preferably made of aluminum or an aluminum alloy. This makes one special high plastic deformability of the spacer profile and a particularly low one Springback reached after bending

Der Durchmesser der Drähte liegt bevorzugt bei weniger als 3 mm, insbesondere bei etwa 1 mm, während die Flach- oder Winkelprofile im allgemeinen eine Dicke von weniger als 3 mm, bevorzugt eine Dicke von weniger als 1 mm, aufweisen. Durch eine solche Wahl der Durchmesser der Drähte bzw. der Dicke der Profile wird eine gute plastische Verformbarkeit bei geringen Materialkosten und geringem Gewicht des Abstandhalterprofils sichergestellt.The diameter of the wires is preferably less than 3 mm, in particular about 1 mm, while the flat or angular profiles generally have a thickness of less than 3 mm, preferably have a thickness of less than 1 mm. By such a choice of The diameter of the wires or the thickness of the profiles becomes a good plastic deformability ensured with low material costs and low weight of the spacer profile.

Die Verstärkungselemente sind bevorzugt in Querschnitts-Eckbereichen des Abstandhalterprofils angeordnet. Diese Bereiche sind, da sie beim Biegeprozeß durch Dehnung oder Stauchung besonders beansprucht werden, sehr empfindlich, und Schäden treten bei herkömmlichen Profilen während des Biegeprozesses besonders an diesen Stellen auf. Die Anordnung der Verstärkungselemente in diesen Bereichen verhindert das Auftreten solcher Schäden. Werden Verstärkungselemente in Form von Drähten oder Winkelprofilen zumindest im Bereich beider Enden der beiden Seitenwände angeordnet, so erhöht sich hierdurch das Biegewiderstandsmoment des Abstandhalterprofils in vorteilhafter Weise, so daß eine besonders gute Kaltbiegbarkeit erreicht wird The reinforcing elements are preferably in cross-sectional corner areas of the spacer profile arranged. These areas are because they are in the bending process due to stretching or compression be particularly stressed, very sensitive, and damage occurs with conventional Profiles during the bending process, especially at these points. The Arrangement of the reinforcing elements in these areas prevents the occurrence such damage. Are reinforcing elements in the form of wires or angle profiles arranged at least in the region of both ends of the two side walls, this increases the bending resistance moment of the spacer profile in an advantageous manner, so that particularly good cold bendability is achieved

In einer anderen bevorzugten Ausführungsform erstrecken sich Flach- oder Winkelprofile im wesentlichen über die gesamte Höhe der Seitenwände der Abstandhalterprofils. Durch das so entstehende hohe Biegewiderstandsmoment wird den Seitenwänden eine besonders hohe Formstabilität verliehen, so daß das Auftreten störender Verformungen zuverlässig vermieden wird.In another preferred embodiment, flat or angular profiles extend in the essentially over the entire height of the side walls of the spacer profile. Because of that The resulting high bending moment becomes particularly high for the side walls Dimensional stability imparted, so that the occurrence of disturbing deformations reliably avoided becomes.

Bei einer weiteren bevorzugten Ausführungsform entspricht die Querschnittsform der in Querschnitts-Eckbereichen des Abstandhalterprofil vorgesehenen Winkelprofile im wesentlichen dem Querschnitt dieser Eckbereich, so daß ein guter Schutz des Abstandhalterprofils während des Biegeprozesses und der allgemeinen Handhabung sowie eine hohe Formstabilität erreicht wird.In a further preferred embodiment, the cross-sectional shape corresponds to that in FIG Cross-sectional corner areas of the spacer profile provided angle profiles essentially the cross section of this corner area, so that good protection of the spacer profile during the bending process and general handling as well as high dimensional stability is achieved.

Es liegt im Rahmen der Erfindung, Verstärkungselemente aus unterschiedlichen Materialien innerhalb eines Profils vorzusehen. Auch können Verstärkungselemente aus Verbundwerkstoffen vorgesehen sein. Die Verstärkungselemente können in ihrer Längsrichtung oder auch über ihren Querschnitt unterschiedliche Materialien oder unterschiedliche Dicken aufweisen.It is within the scope of the invention to use reinforcing elements made of different materials to be provided within a profile. Reinforcing elements made of composite materials can also be used be provided. The reinforcing elements can in their longitudinal direction or have different materials or different thicknesses over their cross section.

Als besonders gut geeignete wärmeisolierende Materialien für das Abstandhalterprofil haben sich thermoplastische Kunststoffe mit einem Wärmeleitwert λ < 0,3 W/ (m • K), z. B. Polypropylen, Polyethylenterephthalat, Polyamid oder Polycarbonat, erwiesen. Der Kunststoff kann übliche Füllstoffe, Additive, Farbstoffe, Mittel zum UV-Schutz usw. enthalten.Have particularly suitable heat-insulating materials for the spacer profile thermoplastic materials with a thermal conductivity λ <0.3 W / (m • K), z. B. polypropylene, Polyethylene terephthalate, polyamide or polycarbonate. Plastic may contain common fillers, additives, dyes, UV protection agents, etc.

Vorzugsweise ist eine sich im wesentlichen über die gesamte Breite und Länge des Abstandhalterprofils erstreckende diffusionsdichte Schicht aus einem Material mit einem Wärmeleitwert λ < 50 W/ (m • K) vorgesehen. Als bevorzugte Materialien für die diffusionsdichte Schicht haben sich Metalle herausgestellt, insbesondere Weißblech oder auch Edelstahl. Die diffusionsdichte Schicht kann ferner aus einem Kunststoff, wie einem Fluorpolymer, Polyvinylidenchlorid oder Ethylvinylacetat bestehen. Die diffusionsdichte Schicht kann durch physikalische oder chemische Beschichtungsverfahren wie beispielsweise durch Sputtern oder Plasmapolymerisation aufgebracht werden. Vorzugsweise wird sie jedoch in Folienform stoffschlüssig mit dem Profil verbunden. Dabei meint "stoffschlüssig verbinden" das dauerhafte Verbinden der beiden Komponenten des Verbundes beispielsweise durch Auflaminieren, ggf. über einen Haftvermittler, durch Einbetten oder ähnliche Techniken.A spacer profile is preferably substantially the entire width and length extending diffusion-tight layer made of a material with a thermal conductivity λ <50 W / (m • K) is provided. As preferred materials for the diffusion-tight Layer has turned out to be metals, especially tinplate or stainless steel. The Diffusion-tight layer can also be made of a plastic, such as a fluoropolymer, polyvinylidene chloride or ethyl vinyl acetate. The diffusion-tight layer can pass through physical or chemical coating processes such as sputtering or Plasma polymerization can be applied. However, it is preferably in foil form cohesively connected to the profile. Here means "cohesive connection" for example, by permanently connecting the two components of the network Laminate, if necessary using an adhesion promoter, by embedding or similar techniques.

Die diffusionsdichte Schicht wird vorzugsweise auch im Bereich der Seitenwände angeordnet.The diffusion-tight layer is preferably also arranged in the region of the side walls.

Aus Kostengründen und aus produktionstechnischen Gründen wird die diffusionsdichte Schicht bevorzugt auf die Außenseite der Außenwand und gegebenenfalls der Seitenwände der Kammer aufgebracht. Sie kann aber auch auf deren Innenseite angeordnet oder in die Wände eingebettet werden. Dadurch kann der Biegeprozeß je nach Biegeanlage weiter vereinfacht werden, da auf diese Weise ein direkter Kontakt der mechanisch empfindlichen diffusionsdichten Schicht mit kraftausübenden Elementen der Biegeanlage vermieden werden kann. Außerdem kann hierdurch ein dauerhafter Schutz der diffusionsdichten Schicht sichergestellt werden.For reasons of cost and production technology, the diffusion density becomes Layer preferably on the outside of the outer wall and optionally the side walls applied to the chamber. But it can also be arranged on the inside or in the Walls are embedded. As a result, the bending process can continue depending on the bending system be simplified, since in this way a direct contact of the mechanically sensitive diffusion-tight layer with force-exerting elements of the bending system can be avoided can. This can also provide permanent protection for the diffusion-tight layer be ensured.

Die diffusionsdichte Schicht kann zusätzlich mit einer Schutzschicht versehen werden, um z. B. Alterungsprozesse oder Strahlungseinflüsse oder auch Beschädigungen durch mechanische Beanspruchungen weitgehend zu vermeiden.The diffusion-tight layer can additionally be provided with a protective layer in order, for. B. aging processes or radiation influences or damage due to mechanical Avoid stress to a large extent.
