Description

Die Erfindung betrifft eine Mehrscheiben-Isolierglaseinheit,bestehend aus mindestens zwei parallelen Glasscheiben und zwischen den Randzonen ihrer aufeinander zuweisenden Flächen angeordneten Distanzrahmen, von denen jeder aus Profilrohren und aus Winkelstücken gebildet ist, welche mit Zapfen in die Hohlräume der Profilrohre einstehen und welche Eckkörper mit zwei zueinander und zu den Glasscheiben parallelen seitlichen Anlageflächen enthalten, die im wesentlichen in den gleichen Ebenen mit den zu den Glasscheiben parallelen seitlichen Anlageflächen der Profilrohre liegen, sowie aus zwischen den Anlageflächen derDistanzrahmen und den Randzonen angeordneten, eine Dampfdiffusionssperre bildenden Elastomerstreifen, wobei mindestens zwei verschließbare Gaseinfüll- bzw. Gasauslaßbohrungen durch die Winkelstücke jedes Distanzrahmens von der Außenseite zu den vom Distanzrahmen und den Glasscheiben umgrenzten Scheibenzwischenraum geführt sind und wobei im Hohlraum mindestens eines Profilrohres jedes Distanzrahmens auf mindestens einem Teil seiner Längenerstreckung ein Trocknungsmittel enthalten ist, das über Durchbrechungen mit diesem Scheibenzwischenraum in Verbindung steht.The invention relates to a multi-pane insulating glass unit, consisting of at least two parallel glass panes and spacer frames arranged between the edge zones of their mutually facing surfaces, each of which is formed from profile tubes and from angle pieces which protrude into the cavities of the profile tubes with pegs and which corner bodies with two contain lateral contact surfaces parallel to one another and to the glass panes, which lie essentially in the same planes with the lateral contact surfaces of the profiled tubes parallel to the glass panes, and from between the system surfaces of the spacer frame and the edge zones arranged, forming a vapor diffusion barrier, elastomer strips, wherein at least two closable gas filler or gas outlet bores are led through the angle pieces of each spacer frame from the outside to the space between the panes delimited by the spacer frame and the glass panes, and each spacer frame in the cavity at least part of its length is a desiccant, which is connected to this space between the panes by perforations.

Bei bekannten derartigen Mehrscheiben-Isolierglaseinheiten (DE-PS 24 10 303; DE-OS 24 62 494) sind die beiden, in die Hohlräume der Profilrohre des Distanzrahmens einstehenden Zapfen der Winkelstücke unmittelbar an dessen Eckkörper angeformt, dergestalt, daß die von einem Winkel stuck verbundenen Profilrohre direkt aneinandergrenzen. Die Gaseinfüll- bzw. Gasauslaßbohrungen, welche der Einbringung von trockener Luft oder eines Leicht- oder Schwergases in den vom Distanzrahmen und den Scheibenzwischenraum dienen, durchqueren den Eckkörper schräg zu den Zapfen, so daß die Achsen dieser Bohrungen angenähert in den Diagonalen der Glasscheiben verlaufen. Die gleiche Anordnung der Gaseinfüll- bzw. Gasauslaßbohrungen zeigen Mehrscheiben-Isolierglaseinheiten mit einem Winkelstück angenähert gleichbleibenden Querschnitts (US-PS 3 280 523).In known such multi-pane insulating glass units (DE-PS 24 10 303; DE-OS 24 62 494), the two, protruding into the cavities of the profile tubes of the spacer frame of the elbows are formed directly on the corner body, such that the stucco from an angle directly join the connected profile tubes. The gas filler or gas outlet bores, which serve to introduce dry air or a light or heavy gas into the space between the spacer frame and the space between the panes, cross the corner body at an angle to the pegs, so that the axes of these bores run approximately in the diagonals of the glass panes. The same arrangement of the gas filling or gas outlet bores are shown in multi-pane insulating glass units with an angle piece of approximately the same cross section (US Pat. No. 3,280,523).

Nachteilig ist beim Bekannten, daß durch die Gaseinfüll- bzw. Gasauslaßbohrungen der Distanzrahmen an einer hinsichtlich seiner Festigkeit besonders kritischen Stelle geschwächt wird bzw. daß durch Festigkeitsüberlegungen die Durchmesser dieser Bohrungen klein gehalten werden müssen, wodurch wiederum nur Sonden geringer Stärke in den vom Rahmen und den Glasscheiben begrenzten Scheibenzwischenraum einführbar sind, wodurch ein Gasaustausch nur langsam erfolgen kann. Trotz bester Säuberung der Glasscheiben vor dem Zusammenbau mit dem Distanzrahmen können sich an der Innenseite der Glasscheiben noch Staubteilchen befinden, an denen die Sonde bei ihrer Einführung Spuren hinterläßt, welche wegen ihrer Erstreckung diagonal zur Isolierglaseinheit für das Auge besonders deutlich in Erscheinung treten. Ferner ist am Bekannten zu bemängeln, daß die Mündungen der Gaseinfüll- bzw. Gasauslaßbohrungen gerade an hinsichtlich einer Wasserdampf-Diffusion besonders gefährdeten Stellen liegen, welche eine möglichst hohe überdeckung mit einer weiteren Dichtungsmasse erhalten sollen.A disadvantage of the known that the spacer frame is weakened at a particularly critical point with regard to its strength by the gas filler or gas outlet bores or that the diameter of these bores must be kept small due to strength considerations, which in turn means only low-strength probes in the frame and limited space between the panes of glass can be inserted, so that gas exchange can take place only slowly. Despite the best cleaning of the glass panes before assembly with the spacer frame, there may still be dust particles on the inside of the glass panes, on which the probe leaves traces when they are inserted, which are particularly evident to the eye due to their extension diagonally to the insulating glass unit. Furthermore, it is to be criticized in the known that the mouths of the gas filling or gas outlet bores are precisely at points which are particularly at risk with respect to water vapor diffusion and which should receive as much coverage as possible with a further sealing compound.

Es ist weiterhin bekannt, die Gaseinfüll- bzw. Gasauslaßbohrungen in den Profilrohren des Distanzrahmens anzuordnen. Nachteilig ist hierbei, daß bei den für die erwünschten großen Sondenstärken erforderlichen Bohrungsdurchmesser eine bedeutende Schwächung der im allgemeinen nur dünnwandigen Profilrohre und damit des Distanzrahmens eintritt, wodurch wiederum Leckstellen zwischen Distanz« rahmen und Glasscheiben entstehen können. Die Profilrohre enthalten in der Regel auch ein Trocknungsmittel, welches mit dem Scheibenzwischenraum über Durchbrechungen in Verbindung steht, deren Abmessungen so gewählt sind, daß das Trocknungsmittel nicht in den Scheibenzwischenraum gelangen kann. Werden nun Gaseinfüll- bzw. Gasauslaßbohrungen in den Profilrohren vorgesehen, so müssen zusätzliche Vorkehrungen, beispielsweise in die Profilrohre eingesetzte Stopfen, getroffen werden, um zu verhindern, daß das Trocknungsmittel in den Scheibenzwischenraum gelangt.It is also known to arrange the gas filling or gas outlet bores in the profile tubes of the spacer frame. The disadvantage here is that with the bore diameters required for the desired large probe thicknesses, there is a significant weakening of the generally thin-walled profile tubes and thus of the spacer frame, which in turn causes leaks between the spacing « frames and glass panes can arise. The profile tubes usually also contain a drying agent, which is connected to the space between the panes through openings, the dimensions of which are selected so that the drying agent cannot get into the space between the panes. If gas filling or gas outlet bores are now provided in the profile tubes, additional precautions, for example plugs inserted into the profile tubes, must be taken to prevent the desiccant from getting into the space between the panes.

Aufgabe der vorliegenden Erfindung ist es, eine Mehrscheiben-Isolierglaseinheit zu schaffen, welche bei geringem Aufwand einen schnellen Gasaustausch des Scheibenzwischenraumes ohne deutliche Spuren an den Glasscheiben ermöglicht und beste Dichtigkeit gewährleistet.The object of the present invention is to provide a multi-pane insulating glass unit which, with little effort, enables a rapid gas exchange of the space between the panes without clear traces on the glass panes and ensures the best seal.

Diese Aufgabe wird, ausgehend von einer Mehrscheiben-Isolierglaseinheit der eingangs genannten Art, erfindungsgemäß dadurch gelöst, daß jeder Distanzrahmen mindestens ein Winkelstück aufweist, welches zwischen dem Eckkörper und mindestens dem einen seiner beiden Zapfen ein Schenkelstück enthält, dessen seitliche Anlageflächen jeweils mit den seitlichen Anlageflächen des Eckkörpers und der Profilrohre im wesentlichen in gemeinsamen Ebenen liegen und daß sich durch diese Schenkelstücke die Gaseinfüll- bzw. Gasauslaßbohrungen erstrecken, deren Achsen im wesentlichen parallel zu den seitlichen Anlageflächen und rechtwinkelig zum Schenkelstück verlaufen.This object is achieved, starting from a multi-pane insulating glass unit of the type mentioned, according to the invention in that each spacer frame has at least one angle piece, which contains a leg piece between the corner body and at least one of its two pins, the lateral contact surfaces of which each with the lateral contact surfaces of the corner body and the profile tubes lie essentially in common planes and that the gas filling or gas outlet bores extend through these leg pieces, whose axes are essentially parallel to the lateral contact surfaces and perpendicular to the leg piece.

Die in den Fig. 1-5 veranschaulichte erste Ausführungsform der Erfindung besteht im wesentlichen aus einem in seiner Gesamtheit mit 1 bezeichneten Distanzrahmen, welcher über Elastomerstreifen 2a, 2b abdichtend zwischen den Randzonen 3a, 3b zweier Glasscheiben 4a, 4b angeordnet ist. Die Elastomerstreifen bestehen aus einem elastischplastischen Dichtungsmaterial, vorzugsweise einer Butyl-Dichtmasse.The first embodiment of the invention illustrated in FIGS. 1-5 essentially consists of a spacer frame, designated in its entirety by 1, which is arranged sealingly between the edge zones 3a, 3b of two glass panes 4a, 4b via elastomer strips 2a, 2b. The elastomer strips consist of an elastic-plastic sealing material, preferably a butyl sealing compound.

Der Distanzrahmen 1 besteht seinerseits aus vier Profilrohren 5, welche durch in ihrer Gesamtheit mit 6 bezeichnete Winkelstücke verbunden sind. Mindestens eines der Profilrohre 5 ist mindestens teilweise mit einem Trocknungsmittel 7 gefüllt, welches über eine Mehrzahl von Durchbrechungen 8 mit gegenüber der Korngröße des Trocknungsmittels kleinerem Querschnitt mit dem Scheibenzwischenraum 9 in Verbindung steht, der von den Glasscheiben 4a, 4b, dem Distanzrahmen 1 und den Elastomerstreifen 2a, 2b begrenzt wird. Die von den über den Distanzrahmen 1 vorstehenden Bereichen der Randzonen 3a, 3b der Glasscheiben 4a, 4b gebildete Vertiefung ist vollständig mit einer zusätzlichen Dichtungsmasse 10 gefüllt.The spacer frame 1 in turn consists of four profile tubes 5, which are connected by angle pieces designated 6 in their entirety. At least one of the profile tubes 5 is at least partially filled with a drying agent 7, which is connected via a plurality of perforations 8 with a smaller cross-section than the grain size of the drying agent to the pane space 9, which of the glass panes 4a, 4b, the spacer frame 1 and the Elastomer strip 2a, 2b is limited. The depression formed by the regions of the edge zones 3a, 3b of the glass panes 4a, 4b projecting above the spacer frame 1 is completely filled with an additional sealing compound 10.

Der Distanzrahmen 1 enthält mindestens zwei Winkelstücke 6 der in den Fig. 3-5 näher veranschaulichten Bauart. Jedes dieser Winkelstücke 6 ist einstückig aus Kunststoff oder Metall gefertigt und besitzt einen Eckkörper 11, von dem einerseits ein Zapfen 12a und andererseits rechtwinkelig hierzu ein Schenkelstück 13 ausgeht, das sich wiederum in einen Zapfen 12b fortsetzt. Die Zapfen 12a, 12b sind an die Hohlräume 5c der Profilrohre 5 angepaßt und in diesen kraftschlüssig gehalten, wobei querverlaufende Halterippen 14 für eine gleichmäßige Anpreßkraft sorgen. Die äußere Begrenzung des Eckkörpers 11 bildet eine Schrägfläche llb, die sich lotrecht zu den Glasscheiben 4a, 4b und mit einem Winkel von 45° zu den Längsachsen der Zapfen 12a, 12b erstreckt und mehr Raum für die zusätzliche Dichtungsmasse 10 schafft.The spacer frame 1 contains at least two angle pieces 6 of the type illustrated in greater detail in FIGS. 3-5. Each of these angles Pieces 6 is made in one piece from plastic or metal and has a corner body 11, on the one hand a pin 12a and on the other hand at right angles to this a leg piece 13, which in turn continues into a pin 12b. The pins 12a, 12b are adapted to the cavities 5c of the profiled tubes 5 and held there in a force-fitting manner, transverse retaining ribs 14 ensuring a uniform contact pressure. The outer boundary of the corner body 11 forms an inclined surface 11b which extends perpendicular to the glass panes 4a, 4b and at an angle of 45 ° to the longitudinal axes of the pins 12a, 12b and creates more space for the additional sealing compound 10.

Die äußere Querschnittsform des Schenkelstücks 13 entspricht derjenigen des ihr zugeordneten Profilrohres 5. Die seitlichen, d.h. den Glasscheiben 3a, 3b zugewandten und die Elastomerstreifen 2a, 2b tragenden Anlageflächen lla des Eckkörpers 11 liegen in den gleichen Ebenen mit den entsprechenden Anlageflächen 13a des Schenkelstücks 13 und den Anlageflächen des auf die Zapfen 12a, 12b aufgeschobenen Profilrohres 5.The outer cross-sectional shape of the leg piece 13 corresponds to that of the profiled tube 5 assigned to it. The contact surfaces 11a of the corner body 11 facing the glass panes 3a, 3b and bearing the elastomer strips 2a, 2b lie in the same planes with the corresponding contact surfaces 13a of the leg piece 13 and the contact surfaces of the profiled tube 5 pushed onto the pins 12a, 12b.

Durch das Schenkel stück 13 erstreckt sich eine Gaseinfüll- bzw. Gasauslaßbohrung 15, deren Achse 15a parallel zur Längsachse des Zapfens 12a verläuft. Durch diese Bohrung 15 kann unmittelbar oder durch eine (nicht dargestellte Sonde) ein Gas in den Scheibenzwischenraum 9 eingebracht oder von diesen ausgelassen werden. Zum Verschluß ist ein in Fig. 3 gesondert veranschaulichter Verschlußstopfen 16 vorgesehen, der mit seinem kappenartigen Rand den äußeren Umfang der Bohrung 15 übergreift. Eine weitere Abdichtung der Bohrung erfolgt mit der zusätzlichen Dichtungsmasse 10.Through the leg piece 13 extends a gas filling or gas outlet bore 15, the axis 15a of which runs parallel to the longitudinal axis of the pin 12a. A gas in the disks can pass through this bore 15 directly or through a (not shown) probe space 9 are introduced or omitted by these. For the closure, a closure plug 16, separately illustrated in FIG. 3, is provided, which overlaps the outer circumference of the bore 15 with its cap-like edge. A further sealing of the bore takes place with the additional sealing compound 10.

Die zweite Ausführungsform der Erfindung unterscheidet sich von der ersten nur durch eine andere Gestaltung des in seiner Gesamtheit mit 6' bezeichneten Winkelstücks, das im folgenden nur insoweit beschrieben wird als Abweichungen gegenüber der ersten Ausführungsform vorliegen. Die Zapfen 12'a und 12'b sind mit eng aufeinanderfolgenden Halterippen 14 versehen und, ausgehend von ihren freien Enden, durch Schlitze 17 jeweils in einen stärkeren Lappen 17a und einen schwächeren Lappen 17b geteilt, so daß die federnde Anpressung im Hohlraum 5c der Profilrohre 5 verbessert wird. Die Fig. 6 zeigt jeweils einen Zapfen 12'a im Anlieferungszustand und einen Zapfen 12'b im Einbauzustand. Ein an die Lappen 17a, 17b anschließender erster Abschnitt der Zapfen ist an die Querschnittsform des Hohlraums 5c der Profilrohre 5 angepaßt. Ein daran anschließender zweiter Abschnitt, der sich in einem Fall in die äußere Begrenzungsfläche 13b des Schenkelstücks 13', im anderen Fall in das Eckstück 11' eben fortsetzt, weist äußere Begrenzungsflächen 18 auf, welche bezüglich des außen liegenden Teiles des Hohlraumes 5c der Profilrohre 5 zurückversetzt sind.The second embodiment of the invention differs from the first only by a different design of the angle piece, designated as a whole by 6 ', which is described below only to the extent that there are deviations from the first embodiment. The pins 12'a and 12'b are provided with closely spaced holding ribs 14 and, starting from their free ends, are divided by slots 17 into a stronger tab 17a and a weaker tab 17b, so that the resilient pressure in the cavity 5c of the profile tubes 5 is improved. 6 each shows a pin 12'a in the delivery state and a pin 12'b in the installed state. A first section of the pins adjoining the tabs 17a, 17b is adapted to the cross-sectional shape of the cavity 5c of the profile tubes 5. A second section adjoining this, which in one case continues into the outer boundary surface 13b of the leg piece 13 ', in the other case into the corner piece 11', has outer boundary surfaces 18 which relate to the outer part of the cavity 5c of the profiled tubes 5 are set back.

Es wird hierdurch mehr Raum für die zusätzliche Dichtungsmasse 10 (vergl. Fig. 1 und 2) geschaffen und damit die Abdichtung der Gaseinfüll- bzw. Gasauslaßbohrung 15, sowie möglicher Leckwege zwischen dem Winkelstück 6', den Profilrohren 5 und den Glasscheiben 3a, 3b verbessert. Zu dem gleichen Zweck weist der Eckkörper 11' außen eine Abrundung 11'b auf.This creates more space for the additional sealing compound 10 (see FIGS. 1 and 2) and thus the sealing of the gas filling or gas outlet bore 15, as well as possible leakage paths between the angle piece 6 ', the profile tubes 5 and the glass panes 3a, 3b improved. For the same purpose, the corner body 11 'has a rounded portion 11'b on the outside.

Gemäß einer dritten, in den Zeichnungen nicht veranschaulichten Ausführungsform können in dem gleichen Schenkelstück 13 bzw. 13' zwei oder mehr Gaseinfüll- bzw. Gasauslaßbohrungen 15 vorgesehen werden, deren Bohrungsachsen zueinander und-zum Zapfen 12a, bzw. 12'a parallel verlaufen und in einer gemeinsamen, zur Glasscheibe 3b parallelen Ebene liegen. Für den Aufbau des Distanzrahmens genügt dann ein derartig ausgebildetes Winkelstück, während die restlichen Winkelstücke ohne Gaseinfüll- bzw. Gasauslaßbohrungen in an sich bekannter Bauart ausgebildet sein können. Für Isolierglaseinheiten extremer Größe und/oder mit geringem Scheibenabstand (beispielsweise 12 mm und weniger) ist es zweckmäßig, zwei derartig ausgebildete Winkelstücke 6 bzw. 6' je Distanzrahmen zu verwenden, damit der Gasfüllvorgang des Scheibenzwischenraumes 9 rasch erfolgen kann, ohne daß ein schädlicher Druckanstieg erfolgt.According to a third embodiment, not illustrated in the drawings, two or more gas filling or gas outlet bores 15 can be provided in the same leg piece 13 or 13 ', the bore axes of which run parallel to one another and to the pin 12a or 12'a and in a common plane parallel to the glass pane 3b. An angle piece designed in this way is then sufficient for the construction of the spacer frame, while the remaining angle pieces can be designed in a manner known per se without gas filling or gas outlet bores. For insulating glass units of extreme size and / or with a small pane spacing (for example 12 mm and less), it is expedient to use two angle pieces 6 and 6 'per spacer frame designed in this way, so that the gas filling process of the pane interspace 9 can be carried out quickly without a harmful pressure increase he follows.
