Abstract

The extruded aluminum spacer frame for insertion between the light-transmitting plates of an insulating-glass pane is formed with one or more pairs of transversely extending aligned openings for admission of a gas into the space within the confines of the frame, for evacuation of a gas from such space, or for regulation of the pressure within the space. If the openings are to be sealed, a tough elastic sealing compound is introduced by way of one opening of each pair so as to form in the internal space of the frame a block which sealingly contacts the inner side of the frame all the way around both openings of the respective pair. A plug is thereupon threaded or driven into one of the openings and close to or even into the other opening in order to urge the mass of sealing compound into sealing contact with the frame around both openings as well as to be maintained in sealing contact with the adjacent material of the compound.

Description

Die Erfindung betrifft einen abstandhaltenden Rahmen für die Scheiben einer Isolierverglasung, der aus wenigstens einem von Stegen gebildeten Hohlprofil besteht, welches vorzugsweise mit Trockenmittel gefüllt ist, wobei der Rahmen wenigstens eine seine von den Scheiben nicht beaufschlagten Stege durchsetzende Lochung, vorzugsweise Bohrung, zum Be- und/oder Entlüften aufweist, die in eingebautem Zustand der Isolierverglasung gasdicht verschlossen ist oder wird.The invention relates to a spacing frame for the panes of insulating glazing, which consists of at least one hollow profile formed by webs, which is preferably filled with desiccant, the frame having at least one perforation, preferably a bore, penetrating its webs not acted upon by the panes, for loading and / or has ventilation, which is or is closed in a gas-tight manner in the installed state of the insulating glazing.

Ein solcher Rahmen ist vor allem bei Isolierverglasungen bekannt, die nach ihrer Fertigung mit einem anderen Gas als Luft gefüllt werden sollen, bei denen also dieses Gas eingefüllt und die bisher vorhandene Luft abgelassen werden soll. Dabei sind in der Regel zwei Lochungen am Rahmen vorgesehen, deren eine nahe dem unteren und deren andere nahe dem oberen Rand dieses Rahmens angeordnet ist. Strömt nun das Gas durch die untere Lochung ein, kann die Luft durch die obere Lochung entweichen. Anschließend müssen die Lochungen gasdicht und dampfdicht verschlossen werden, was häufig durch einen an der Außenseite des Rahmens zwischen den Scheiben der Isolierverglasung umlaufenden Dichtungsbelag geschieht. Nachteilig ist dabei, daß das Verschließen der Lochung selbst entweder unterlassen wird, so daß Dampfdichtigkeit selbst bei einem relativ dichten äusseren Dichtungsbelag nicht mit Sicherheit erreicht wird, oder ein unschöner Dichtungspfropfen an der Innenseite des Rahmens sichtbar wird, ohne daß dieser eine Dampfdichtigkeit über Jahre gewährleisten kann. Darüber hinaus muß an dem mit dieser Öffnung versehenen Rahmenschenkel auf eine Trockenmittelfüllung verzichtet werden, damit dieses Trockenmittel während des Gasaustausches und bei der sonstigen Handhabung dieser Isolierverglasung nicht in den Zwischenraum zwischen den Scheiben rieseln kann.Such a frame is particularly known in the case of insulating glazing which, after its manufacture, is to be filled with a gas other than air, in which case this gas is to be filled in and the air previously present is to be discharged. As a rule, two perforations are provided on the frame, one of which is arranged near the lower edge and the other near the upper edge of this frame. If the gas now flows in through the lower perforation, the air can escape through the upper perforation. Then the perforations must be sealed gas-tight and vapor-tight, which is often due to a on the outside of the frame between the Schei beneath the insulating glazing circumferential sealing covering happens. The disadvantage here is that the perforation itself is either not closed, so that vapor tightness is not achieved with certainty even with a relatively dense outer sealing covering, or an unsightly sealing plug is visible on the inside of the frame without this ensuring vapor tightness for years can. In addition, a desiccant filling must be dispensed with on the frame leg provided with this opening, so that this desiccant cannot trickle into the space between the panes during gas exchange and other handling of this insulating glazing.

Es ist ferner bei Isolierverglasungen bekannt, daß bei einer Fertigung im Tal und-einem Einsatz in großer Höhe ein Druckausgleich-geschaffen werden-muß. Dabei genügt eine einzige Lochung der eingangs genannten Art in dem Rahmen, für die hinsichtlich der Abdichtung die gleichen Nachteile gelten.It is also known in the case of insulating glazing that pressure compensation must be created when manufacturing in the valley and when used at high altitudes. A single perforation of the type mentioned at the outset is sufficient for which the same disadvantages apply with regard to the sealing.

Es besteht deshalb die Aufgabe, einen Rahmen der eingangs erwähnten Art zu schaffen, der mit quer zu ihm verlaufenden Lochungen oder Bohrungen zum Be- und/oder Entlüften und/oder eine Gasfüllung versehen werden kann, die dampfdicht verschließbar sind, selbst wenn ein äußerer Dichtungsbelag des Rahmens nur relativ dünn oder gar nicht vorhanden ist. Dabei soll es auch möglich sein, diese Querlochungen an mit Trockenmittel gefüllten Rahmenschenkeln vorzusehen, um möglichst viel Trockenmittel im gesamten Rahmen einer solchen Isolierverglasung zur Verfügung zu haben, ohne daß dieses Trockenmittel aus der Lochung herausrieseln kann. Ferner gehört es zur Aufgabe der vorliegenden Erfindung, ein Verfahren zur Herstellung eines derartigen Rahmens und eine Vorrichtung zur Durchführung dieses Verfahrens zu schaffen, womit ein Rahmen einerseits mit wenigstens einer oder mehreren quer verlaufenden Lochungen versehen werden kann, dennoch aber bei der fertiggestellten Isolierverglasung Dampfdichtigkeit auch im Bereich dieser Lochung erzielt wird.It is therefore an object of the invention to provide a frame of the type mentioned at the outset which can be provided with perforations or bores for ventilation and / or ventilation and / or a gas filling which run transversely to it and can be closed in a vapor-tight manner, even if an outer sealing coating is used of the frame is only relatively thin or does not exist at all. It should also be possible to provide these transverse perforations on frame legs filled with desiccant in order to have as much desiccant as possible in the entire frame of such insulating glazing without this desiccant being able to trickle out of the perforation. It is also part of the task of the present Invention to provide a method for producing such a frame and an apparatus for performing this method, whereby a frame can be provided on the one hand with at least one or more transverse perforations, but vapor tightness is also achieved in the area of this perforation in the finished insulating glazing.

Zur Lösung dieser Aufgabe ist der eingangs erwähnte Rahmen dadurch gekennzeichnet, daß das Innere des Rahmens in unmittelbarer Umgebung der Lochung mit Dichtungsmasse ausgefüllt ist, die zumindest zwischen den gelochten Stegen die Innenwand der Lochung bildet, und daß ein in diese Lochung passender und an der Dichtungsmasse anliegender Verschluß vorgesehen ist.To achieve this object, the frame mentioned at the outset is characterized in that the interior of the frame in the immediate vicinity of the perforation is filled with sealing compound, which forms the inner wall of the perforation at least between the perforated webs, and in that a fitting into the perforation and on the sealing compound adjacent closure is provided.

Diese-Dichtungsmasse erfüllt dabei einen doppelten Zweck, indem sie einerseits das Innere des Rahmens gegen die Lochung hin verschließt, so daß der Rahmen bis in den Bereich der Lochung mit Trockenmittel gefüllt sein kann, und andererseits anschließend zusammen mit dem Verschluß den gewünschten dampfdichten Abschluß schafft. Die Lochung wird dabei in vorteilhafter Weise innerhalb des Rahmenumrisses dampfdicht verschlossen, so daß die Dampfdichtigkeit dieser Lochung nicht oder kaum noch von einer äußeren Versiegelung des Rahmens zwischen den Scheiben abhängt. Dabei ist es besonders zweckmäßig, wenn der Verschluß die die Lochung begrenzende Dichtungsmasse in Gebrauchsstellung etwas verdrängt. Beim Einbringen des Verschlusses wird so eine innige Berührung zwischen dem Verschluß und der Dichtungsmasse bewirkt, die für die Dampfdichtigkeit von erheblichem Vorteil ist.This sealant fulfills a dual purpose by, on the one hand, closing the interior of the frame against the perforation, so that the frame can be filled with desiccant up to the area of the perforation, and, on the other hand, then creating the desired vapor-tight seal together with the closure . The perforation is advantageously sealed vapor-tight within the frame outline, so that the vapor-tightness of this perforation does not depend or hardly depends on an external sealing of the frame between the panes. It is particularly useful if the closure somewhat displaces the sealing compound delimiting the perforation in the position of use. When the closure is introduced, an intimate contact between the closure and the sealing compound is brought about, which is of considerable advantage for the vapor tightness.

Eine Ausgestaltung der Erfindung von ganz erheblicher Bedeutung kann darin bestehen, daß als Verschluß eine sich mit ihrem Gewinde in die Innenwand aus Dichtungsmasse einschneidende Schraube vorgesehen ist. Dadurch läßt sich eine besonders innige Verbindung zwischen Verschluß und Dichtungsmasse herstellen, wobei zusätzlich die Berührungsfläche durch die Kontur des Gewindes vergrößert ist, so daß eine entsprechende Dampfdichtigkeit erzielt wird. Darüber hinaus ist die Montage eines solchen Verschlusses einfach. Auch kann dieser Verschluß gegebenenfalls nur teilweise eingeschraubt werden und in dieser Position bleiben, während die Außenbelegung des Rahmens mit Dichtungsmasse durchgeführt wird, so daß danach die Lochung wieder geöffnet werden kann, ohne diese Außenbelegung erheblich beschädigen zu müssen.An embodiment of the invention of very considerable Significance can be that a screw with its thread cutting into the inner wall of sealing compound is provided as the closure. This allows a particularly intimate connection to be made between the closure and the sealing compound, the contact surface being additionally enlarged by the contour of the thread, so that a corresponding vapor tightness is achieved. In addition, the assembly of such a closure is simple. Also, this closure can optionally only be partially screwed in and remain in this position while the outer covering of the frame is carried out with sealing compound, so that the perforation can then be opened again without having to significantly damage this outer covering.

Eine andere Möglichkeit besteht darin, daß als Verschluß ein mit seiner Außenkontur gegenüber der. Lochung bereichsweise vergrößerter, radial nachgiebiger Stopfen vorgesehen ist, der in die Lochung eindrückbar und vorzugsweise an den Rändern des Rahmenprofiles verrastbar ist.Another possibility is that as a closure with its outer contour opposite the. Perforation enlarged, radially flexible plug is provided in some areas, which can be pressed into the perforation and preferably locked at the edges of the frame profile.

Zweckmäßig ist es in jedem Falle, wenn der Verschluß einen Kopf hat, der in Schließstellung an der Außenseite des Rahmens anliegt. Auf diese Weise erhält der Benutzer einen Anschlag, der sicherstellt, daß der Verschluß nicht zu tief eingebracht wird und an der Innenseite des Rahmens austritt.In any case, it is expedient if the closure has a head which, in the closed position, lies against the outside of the frame. In this way, the user receives a stop which ensures that the closure is not inserted too deeply and exits on the inside of the frame.

Der Abstand zwischen der Verdickung des Stopfens und dem Kopf kann etwa der Stärke des Steges des Rahmenprofiles entsprechen und es kann eine Einziehung unmittelbar unter dem Kopf als Verrastung am äußeren Steg des Rahmenprofiles dienen.The distance between the thickening of the plug and the head can correspond approximately to the thickness of the web of the frame profile and a retraction directly under the head can serve as a catch on the outer web of the frame profile.

Die Dichtungsmasse ist zweckmäßigerweise Butylkautschuk, der einerseits eine ausreichende Eigenstabilität hat, um die Innenwandung der Lochung zu bilden und das Trockenmittel von dieser zurückzuhalten, und der andererseits dauerzäh elastisch bleibt und beim Einbringen des Verschlusses mit diesem eine innige Berührung über dessen gesamte Oberfläche eingehen kann.The sealing compound is expediently butyl rubber, which on the one hand has sufficient inherent stability to form the inner wall of the perforation and retain the drying agent from it, and on the other hand remains permanently elastic and can make intimate contact with the entire surface of the closure when it is inserted.

Besonders vorteilhaft ist es, wenn vom Gewinde oder der Durchmesservergrößerung des Stopfens verdrängte Dichtungsmasse die Fugen zwischen dem Verschluß und dem aussenliegenden, gegebenenfalls auch dem innenliegenden Steg des Rahmenprofiles ausfüllt. Somit wird auch an den Durchtrittsstellen des Verschlusses durch die Stege des Rahmenprofiles dort eine dampfdichte Abdichtung erzielt, obwohl der Verschluß selbst gegenüber der Lochung eine übliche Toleranz haben kann.It when the sealant displaced by the thread or the increase in diameter of the stopper fills the joints between the closure and the outside, and possibly also the inside, web of the frame profile is particularly advantageous. A vapor-tight seal is thus also achieved at the passage points of the closure by the webs of the frame profile, although the closure itself can have a customary tolerance with respect to the perforation.

Die Länge des Verschlusses entspricht zweckmäßigerweise mindestens der lichten Weite des Rahmenprofiles in Längsrichtung der Lochung. Dadurch wird sichergestellt, daß die gesamte lichte Weite des Rahmenprofiles von dem Verschluß überdeckt wird. Dabei kann der Verschluß mit seinem dem Scheibeninnenraum zugewandten Ende bis in den gelochten Querschnitt des den Scheibeninnenraum begrenzenden inneren Steges des Rahmenprofiles ragen und vorzugsweise mit dessen dem Scheibenzwischenraum zugewandten Innenfläche etwa bündig abschließen. Somit wird eine bestmögliche Abdichtung der Lochung und gleichzeitig auch ein optisch günstiger Abschluß an der Innenseite des Rahmens erzielt. Dies gilt vor allem dann. wenn die Farbe des Verschlusses der des Rahmen-Werkstoffes entspricht.The length of the closure expediently corresponds to at least the clear width of the frame profile in the longitudinal direction of the perforation. This ensures that the entire clear width of the frame profile is covered by the closure. The closure with its end facing the window interior can protrude into the perforated cross section of the inner web of the frame profile delimiting the window interior and preferably be approximately flush with its inner surface facing the window interspace. In this way, the best possible sealing of the perforation and, at the same time, an optically favorable closure on the inside of the frame is achieved. This is especially true then. if the color of the closure corresponds to that of the frame material.

Der Verschluß kann lösbar sein. wodurch auch nach der Füllung mit dem Gas oder der Be- und/oder Entlüftung noch Korrekturen des Innendruckes möglich sind.The closure can be detachable. whereby even after the filling with the gas or the ventilation and / or ventilation, corrections of the internal pressure are still possible.

Eine weitere Ausgestaltung der Erfindung zur Verbesserung der Be- und Entlüftung kann darin bestehen, daß der Verschluß seinerseits eine in seiner Längsrichtung verlaufende, wenigstens teilweise durch ihn hindurchführende und/oder im im Endbereich insbesondere unmittelbar am Scheibenzwischenraum durchstoßbare Öffnung zum zeitweiligen oder ständigen Aufnehmen einer Kanüle od.dgl. Leitung hat. Dies ermöglicht es, eine solche Kanüle dampfdicht an dem abstandhaltenden Rahmen zu fixieren. Die Isolierverglasung kann dann in ihren Halterahmen eingesetzt werden, bis zu dessen Außenseite die Kanüle reichen kann. Somit läßt sich die Be- und Entlüftung sogar an einem fertig montierten Fenster od.dgl. durchführen. Dabei kann eine Metallkanüle in den Verschluß eingesetzt, vorzugsweise eingelötet sein und-ihrerseits zum Verschließen verlötbar sein. Zwar sind Kanülen zum Be-und Entlüften von Scheiben-Zwischenräumen schon bekannt, jedoch besteht dabei immer das Problem des dampfdichten Verschlusses der von der Kanüle erzeugten Öffnung. Die vorbeschriebene Maßnahme erlaubt es nun1 die Kanüle mit Hilfe des erfindungsgemäßen Verschlusses dampfdicht an dem Rahmen anzubringen und ihrerseits durch Verlöten hermetisch zu verschließen.A further embodiment of the invention for improving the ventilation can consist in that the closure itself has an opening in its longitudinal direction, at least partially passing through it and / or in the end area, in particular, directly penetrable at the disc space, for temporarily or continuously receiving a cannula or the like. Lead. This makes it possible to fix such a cannula to the spacing frame in a vapor-tight manner. The double glazing can then be inserted into its holding frame, up to the outside of which the cannula can reach. Thus, the ventilation and the like even on a fully assembled window. carry out. A metal cannula can be inserted into the closure, preferably soldered in, and in turn solderable for closure. Although cannulas for ventilating and venting interstice gaps are already known, there is always the problem of the vapor-tight closure of the opening created by the cannula. The measure described above now allows 1 to attach the cannula to the frame in a vapor-tight manner with the aid of the closure according to the invention and in turn to seal it hermetically by soldering.

Diese Kanüle hat den weiteren Vorteil, daß sie mit ihrem dem Verschluß am Rahmen abgewandten Ende an ein Druckausgleichssystem für vorzugsweise mehrere Isolierverglasungen anschließbar ist. Somit kann sogar später in eingebautem Zustand eine eventuell erforderliche Be- und Entlüftung bzw. ein Druckausgleich an der Isolierverglasung vorgenommen werden, wobei aber dennoch mit Hilfe des erfindungsgemäßen Verschlusses auch im Bereich der Kanüle Dampfdichtigkeit bestehen bleibt. Etwas derartiges ist z.B. bei Isolierverglasungen denkbar die häufig wechselnden Außendrücken beispielsweise durch einen Wechsel ihrer Höhenlage z.B. an Bergbahnen ausgesetzt sind.This cannula has the further advantage that, with its end facing away from the closure on the frame, it can be connected to a pressure compensation system for preferably a plurality of insulating glazings. This means that any necessary ventilation and pressure equalization can be carried out on the double glazing even when installed, but still with the help of Closure according to the invention also remains vapor-tight in the area of the cannula. Something of this kind is conceivable, for example in the case of insulating glazing, the frequently changing external pressures are exposed, for example, to a change in their altitude, for example on mountain railways.

Die Erfindung betrifft auch ein Verfahren zur Herstellung eines Rahmens aus einem oder mehreren Hohlprofilen, welcher vorzugsweise mit Trockenmittel gefüllt ist und mit wenigstens einer quer verlaufenden Be- und/oder Entlüftungslochung versehen wird.The invention also relates to a method for producing a frame from one or more hollow profiles, which is preferably filled with desiccant and is provided with at least one transverse ventilation and / or ventilation hole.

Dieses Verfahren ist dadurch gekennzeichnet, daß zuerst die Lochung in den Rahmen gebohrt und nach Zurückziehung des Bohrers der Zwischenraum zwischen den gelochten Stegen des Rahmenprofiles um den Bohrungsbereich herum mit Dichtungsmasse ausgespritzt wird. Dadurch wird ein hermetisch dichter Innenkanal geschaffen, der gegenüber dem Hohlprofil einen sicheren Abschluß schafft. Somit kann dieses Verfahren auch bei einem solchen Hohlprofil angewendet werden, welches mit Trockenmittel gefüllt ist. Zwar mag beim Bohren etwas Trockenmittel austreten und dieses kann während des Bohrens abgesaugt werden, jedoch wird dadurch in vorteilhafter Weise sogar Platz für die Dichtungsmasse geschaffen.This method is characterized in that the perforation is first drilled into the frame and, after the drill has been withdrawn, the space between the perforated webs of the frame profile is sprayed with sealing compound around the bore area. This creates a hermetically sealed inner channel, which creates a secure seal with respect to the hollow profile. This method can therefore also be used for a hollow profile which is filled with desiccant. Although some desiccant may escape during drilling and this can be sucked off during drilling, this advantageously even creates space for the sealing compound.

Gleichzeitig kann beim Einspritzen der Dichtungsmasse die Innenwand der Lochung etwa fluchtend mit den Bohrungsrändern in den Profilstegen geformt werden, was mit Hilfe eines entsprechenden in die Lochung einführbaren Formkörpers geschehen kann.At the same time, when the sealing compound is injected, the inner wall of the perforation can be formed approximately flush with the bore edges in the profile webs, which can be done with the aid of a corresponding shaped body that can be inserted into the perforation.

Eine Vorrichtung zur Durchführung des vorbeschriebenen Verfahrens ist dadurch gekennzeichnet daß sie eine Bohrmaschine und eine Spritzvorrichtung für die Dichtungsmasse mit einer Spritzdüse aufweist, welche Spritzdüse in die von dem Bohrer der Bohrmaschine gefertigte Lochung paßt. Dadurch ist es möglich, einerseits die Bohrung anzubringen und dann deren Umgebungsbereich im Inneren des Hohlprofiles mit der Dichtungsmasse auszufüllen.A device for performing the above-described method is characterized in that it has a drill and a spraying device for you tion mass with a spray nozzle, which spray nozzle fits into the hole made by the drill of the drill. This makes it possible, on the one hand, to drill the hole and then to fill its surrounding area inside the hollow profile with the sealing compound.

Besonders zweckmäßig ist es, wenn die Spritzdüse ein zylindrischer Körper ist, an dessen Außenseite die Austrittsöffnungen für das Spritzgut etwa radial angeordnet sind und dessen Endbereich als Verschluß der Bohrungen in den Rahmenstegen dienen. Somit sorgt die Spritzdüse selbst dafür, daß die Lochungen der beiden durchlochten Stege verschlossen sind, während die Dichtungsmasse im Inneren des Hohlprofiles ausgespritzt wird. Darüber hinaus bildet die Spritzdüse selbst den Formkörper, der die Innenwandung der aus Dichtungsmasse gebildeten Lochung formt.It is particularly expedient if the spray nozzle is a cylindrical body, on the outside of which the outlet openings for the spray material are arranged approximately radially and the end region of which serve as a closure of the bores in the frame webs. Thus, the spray nozzle itself ensures that the perforations of the two perforated webs are closed, while the sealing compound is sprayed out inside the hollow profile. In addition, the spray nozzle itself forms the molded body, which forms the inner wall of the perforation formed from sealing compound.

Bohrer und Spritzdüse können an-einem gemeinsamen Maschinengestell oder -ständer miteinander fluchtend aber mit einem Abstand-zwischen sich angeordnet sein, in den das Rahmenprofil paßt, so daß der Bohrer von der einen Seite durch das Profil und die Spritzdüse von der entgegengesetzten Seite in das gebohrte Profil einführbar sind.Drill and spray nozzle can be aligned on a common machine frame or stand but with a distance between them, into which the frame profile fits, so that the drill from one side through the profile and the spray nozzle from the opposite side into the drilled profile are insertable.

Die Spritzvorrichtung kann eine Dosiereinrichtung für das Spritzgut aufweisen, die z.B. zeitgesteuert, vom Gegendruck an der Spritzstelle gesteuert oder mit einer den Bohrungsdurchmesser berücksichtigenden vorgegebenen Menge beaufschlagt ist. Auch sonstige beliebige Dosiervorrichtungen können dabei vorgesehen sein, um sicherzustellen, daß einerseits genügend Dichtungsmasse zum vollständigen Umschließen der Lochung im Inneren des Profiles, aber nicht zu viel Dichtungsmasse eingespritzt wird, die an den Stegen herausquellen könnte. Je nach Profilgröße ist dabei die Menge an Dichtungsmasse entsprechend zu dosieren.The spraying device can have a metering device for the sprayed material, which, for example, is time-controlled, controlled by the counterpressure at the spraying point, or is supplied with a predetermined amount that takes the bore diameter into account. Any other metering devices can also be provided to ensure that on the one hand enough sealing compound is injected to completely enclose the perforation inside the profile, but not too much sealing compound that could swell out on the webs. Depending on the profile size the amount of sealant must be dosed accordingly.

Vor allem bei Kombination einzelner oder mehrerer der vorbeschriebenen Merkmale und Maßnahmen läßt sich ein abstandhaltender Rahmen für die Scheiben einer Isolierverglasung herstellen und benutzen, der eine oder mehrere ihn zwischen den Scheiben durchsetzende Lochungen aufweist, die die Anforderungen an Dampfdichtigkeit aufgrund der aus Dichtungsmasse bestehenden Innenwand der Lochung im Zusammenwirken mit einem entsprechenden Verschluß erfüllen können. Somit ist eine problemlose Be-und Entlüftung einer solchen Scheibe oder ein Gasaustausch auf einfache Weise und ohne Risiko für die spätere Benutzung der Scheibe möglich.Especially when combining one or more of the features and measures described above, a spacing frame for the panes of double glazing can be produced and used, which has one or more perforations penetrating it between the panes, which meet the requirements for vapor tightness due to the inner wall made of sealant Can perform perforation in cooperation with an appropriate closure. A problem-free ventilation of such a pane or a gas exchange is thus possible in a simple manner and without risk for the later use of the pane.

Eine im ganzen mit 1 bezeichnete Isolierverglasung weist zwei Glasscheiben 2 und einen diese auf Abstand haltenden Rahmen 3 auf, welcher mit Trockenmittel gefüllt ist. Man erkennt dies an den feinen Perforationen 4 an der Innenseite dieses Rahmens 3. Dabei ist ein Rahmen 3 vorgesehen, der aus einem einzigen Hohlprofil durch entsprechende Biegungen gebildet ist. Es wäre aber auch möglich, einzelne Rahmenteile, die z.B. auf Gehrung geschnitten sind, zu einem solchen Rahmen 3 zu machen und daran die Erfindung durchzuführen.An insulating glazing, designated as a whole by 1, has two glass panes 2 and a frame 3 which keeps them at a distance and which is filled with desiccant. This can be seen from the fine perforations 4 on the inside of this frame 3. A frame 3 is provided which is formed from a single hollow profile by means of corresponding bends. However, it would also be possible to use individual frame parts, e.g. are mitred to make such a frame 3 and to implement the invention.

Zwischen dem Rahmen 3 und den Scheiben 2 ist in bekannter Weise eine Dichtung 5 vorgesehen. Darüber hinaus kann die Außenseite des Rahmens 3 in der in Fig. 1 dargestellten Weise mit Dichtungsmasse 6 belegt sein.A seal 5 is provided between the frame 3 and the panes 2 in a known manner. In addition, the outside of the frame 3 can be covered with sealing compound 6 in the manner shown in FIG. 1.

Der Rahmen 3 weist seine von den Scheiben 2 nicht beaufschlagten Stege 7 und 8 (Fig.2 bis 4) durchsetzende Lochungen 9, im Ausführungsbeispiel Bohrungen auf, die eine Be- und/oder Entlüftung des Innenraumes 10 zwischen den Glasscheiben 2 auf der Innenseite des Rahmens 3 erlauben. In eingebautem Zustand der Isolierverglasung 1 werden diese Lochungen 9 in der auch in Fig. 1, vor allem aber in den Fig. 2 bis 4 angedeuteten Weise gasdicht verschlossen.The frame 3 has its webs 7 and 8 (FIGS. 2 to 4) which are not acted upon by the panes 2 and which have holes 9 in the exemplary embodiment, bores which provide ventilation and / or ventilation of the interior 10 between the glass panes 2 on the inside of the Allow frame 3. In the installed state of the insulating glazing 1, these perforations 9 are sealed gas-tight in the manner also indicated in FIG. 1, but above all in FIGS. 2 to 4.

In Fig. 1 ist an der oberen der beiden Lochungen 9 angedeutet und in den Fig. 2 bis 4 deutlich dargestellt, daß das Innere des Rahmens 3 in unmittelbarer Umgebung der Lochung 9 mit Dichtungsmasse 11 ausgefüllt ist, die zumindest zwischen den gelochten Stegen 7 und 8 die Innenwand der Lochung 9 bildet. Dadurch wird das schon erwähnte Trockenmittel 12 gleichzeitig von dieser Lochung 9 ferngehalten bzw. das Hohlprofil im Bereich der Lochung 9 so verschlossen, daß kein Trockenmittel 12 austreten kann. Somit kann der Rahmen 3 vollständig mit Trockenmittel gefüllt sein, obwohl er Querlochungen 9 aufweist. Man erkennt ferner vor allem in den Fig. 2 bis 4, daß ein in die Lochung 9 passender und an der Dichtungsmasse 11 anliegender Verschluß 13 vorgesehen ist, der verschiedene Ausführungsformen haben kann. Dieser Verschluß 13 verdrängt die die Lochung 9 begrenzende Dichtungsmasse 11 in Gebrauchsstellung, so daß eine innige und dampfdichte Berührung zwischen dieser Dichtungsmasse 11 und dem Verschluß 13 in Gebrauchsstellung hergestellt ist.In Fig. 1 is at the top of the two perforations 9 indicates and clearly shown in FIGS. 2 to 4 that the interior of the frame 3 in the immediate vicinity of the perforation 9 is filled with sealant 11, which forms the inner wall of the perforation 9 at least between the perforated webs 7 and 8. As a result, the already mentioned drying agent 12 is kept away from this perforation 9 or the hollow profile is closed in the area of the perforation 9 in such a way that no drying agent 12 can escape. Thus, the frame 3 can be completely filled with desiccant, although it has cross holes 9. One also recognizes above all in the Fi g . 2 to 4, that a fitting 13 is provided in the perforation 9 and is in contact with the sealing compound 11, which can have different embodiments. This closure 13 displaces the sealing compound 11 delimiting the perforation 9 in the use position, so that an intimate and vapor-tight contact is produced between this sealant 11 and the closure 13 in the use position.

Gemäß Fig. 2 und 3 kann als Verschluß 13 eine sich mit ihrem Gewinde 14 in die Innenwand aus Dichtungsmasse 11 einschneidende Schraube vorgesehen sein. Gemäß Fig. 4 kann als Verschluß 13 ein mit seiner Außenkontur gegenüber der Lochung 9 vergleichsweise vergrößerter, radial nachgiebiger Stopfen vorgesehen sein, der in die Lochung 9 eindrückbar und an den-Rändern des Rahmenprofiles, im Ausführungsbeispiel des in Gebrauchsstellung außen liegenden Steges 7, verrastbar ist.According to FIGS. 2 and 3, a screw that cuts into the inner wall of sealing compound 11 with its thread 14 can be provided as the closure 13. 4 can be provided as a closure 13 with its outer contour with respect to the perforation 9, a comparatively enlarged, radially flexible plug which can be pressed into the perforation 9 and locked on the edges of the frame profile, in the exemplary embodiment of the web 7 lying outside in the use position is.

In beiden Ausführungsbeispielen hat der Verschluß 13 einen Kopf 15, der in Schließstellung an der Außenseite des Rahmens 3, also des Steges 7, anliegt.In both exemplary embodiments, the closure 13 has a head 15 which, in the closed position, bears against the outside of the frame 3, that is to say the web 7.

. Der Abstand zwischen der Verdickung 16 des Stopfens gemäß Fig. 4 und dem Kopf 15 entspricht dabei etwa der Stärke des Steges 7 und eine Einziehung 17 unmittelbar unter dem Kopf 15 dient als Verrastung an diesem äußeren Steg 7.. The distance between the thickening 16 of the plug according to FIG. 4 and the head 15 corresponds approximately to that The thickness of the web 7 and a retraction 17 directly under the head 15 serve as a catch on this outer web 7.

Die Dichtungsmasse 11 ist zweckmäßigerweise ein dauerzäh elastisch bleibender Werkstoff wie Butylkautschuk. Dadurch ist es möglich, daß die Innenwand der Lochung 9 eine ausreichende Stabilität hat, dennoch aber vom Gewinde 14 oder der Durchmesservergrößerung 16 des Stopfens Dichtungsmasse 11 in die Fugen zwischen dem Verschluß 13 und dem außen liegenden, gegebenenfalls auch dem innen liegenden Steg des Rahmenprofiles verdrängt wird, um auch hier eine hermetische Abdichtung und Ausfüllung zu erzielen, wie es vor allem in den Fig. 2 bis 4 angedeutet ist.The sealing compound 11 is expediently a permanently tough elastic material such as butyl rubber. This makes it possible for the inner wall of the perforation 9 to have sufficient stability, but nevertheless to displace sealant 11 from the thread 14 or the enlarged diameter 16 of the stopper into the joints between the closure 13 and the outer, possibly also the inner, web of the frame profile is to achieve a hermetic seal and filling, as is indicated above all in FIGS. 2 to 4.

In allen Ausführungsbeispielen--entspricht die -Länge des Verschlusses 13 mindestens der lichten-Weite des Rahmenprofiles zwischen seinen beiden Stegen 7 und 8 in Längsrichtung der Lochung 9. Dabei ragt der Verschluß 13 mit seinem dem Scheibeninnenraum 10 zugewandten Ende bis in den gelochten Querschnitt des inneren Steges 8 des Rahmenprofiles und schließt im Ausführungsbeispiel etwa mit dessen dem Scheibenzwischenraum 10 zugewandten Innenfläche bündig ab. Gegebenenfalls kann ein etwas gewölbtes Ende 18 geringfügig überstehen.In all of the exemplary embodiments, the length of the closure 13 corresponds at least to the inside width of the frame profile between its two webs 7 and 8 in the longitudinal direction of the perforation 9. The closure 13, with its end facing the window interior 10, projects into the perforated cross section of the inner web 8 of the frame profile and in the exemplary embodiment is approximately flush with its inner surface facing the pane space 10. If necessary, a slightly curved end 18 can protrude slightly.

Der Verschluß kann lösbar sein, so daß während der Herstellung Korrekturen des Innendruckes möglich sind. Ist der Verschluß 13 eine Schraube, kann er herausgeschraubt werden, während der Stopfen durch Untergreifen seines Kopfes 15 herausgehebelt werden kann, da der Stopfen radial nachgiebig ist. Dies wird unter anderem auch dadurch ermöglicht, weil die Dichtungsmasse dauerzäh-elastisch bleibt, so daß nachträglich wieder ein dampfdichter Verschluß möglich ist.The closure can be detachable, so that corrections to the internal pressure are possible during manufacture. If the closure 13 is a screw, it can be unscrewed, while the plug can be levered out by reaching under its head 15, since the plug is radially flexible. This is made possible, among other things, by the fact that the sealing compound remains permanently tough and elastic, so that a steam is subsequently added tight closure is possible.

In den Fig. 3 und 4 ist angedeutet, daß der Verschluß 13 seinerseits eine in seiner Längsrichtung verlaufende, wenigstens teilweise durch ihn hindurchführende und/oder im Endbereich durchstoßbare Öffnung 19 zum zeitweiligen oder ständigen Aufnehmen einer Kanüle 20 od.dgl. Leitung haben kann. Die Öffnung 19 ist im Ausführungsbeispiel nach Fig. 3 durchgängig und man erkennt dort auch eine eingesetzte und verlötete Kanüle 20. Der Stopfen gemäß Fig. 4 zeigt eine nur teilweise durchgehende Öffnung 19, die bei Bedarf nach innen durchgestoßen werden kann. Diese Öffnung erlaubt außerdem die radiale Nachgiebigkeit. Die Kanüle 20 kann dazu dienen, eine Be- und Entlüftung auch dann noch durchzuführen, wenn die Isolierverglasung 1 in einem Halterahmen montiert ist. Sie kann erforderlichenfalls an-ihrem äußeren Ende durch Verlöten ebenfalls hermetisch -und -dampfdicht verschlossen werden. Außerdem kann sie mit ihrem dem Verschluß 13 abgewandten Ende an ein Druckausgleichssystem anschließbar sein, wenn die Isolierverglasung 1 häufig wechselnden Drücken ausgesetzt werden können soll.3 and 4 it is indicated that the closure 13, in turn, has an opening 19 in its longitudinal direction, at least partially passing through it and / or penetrable in the end region, for the temporary or permanent reception of a cannula 20 or the like. Can have leadership. In the exemplary embodiment according to FIG. 3, the opening 19 is continuous and there is also an inserted and soldered cannula 20. The stopper according to FIG. 4 shows an only partially through opening 19 which can be pushed through inwards if required. This opening also allows radial compliance. The cannula 20 can also be used to perform ventilation and venting even when the insulating glazing 1 is mounted in a holding frame. If necessary, it can also be hermetically and vapor-tightly closed at its outer end by soldering. In addition, it can be connectable to a pressure compensation system with its end facing away from the closure 13 if the insulating glazing 1 is to be able to be exposed to frequently changing pressures.

Fig. 5 zeigt eine im ganzen mit 21 bezeichnete Vorrichtung, mit welcher der Rahmen 3 hergestellt und insbesondere die quer .verlaufenden Lochungen 9 und deren Innenwandung hergestellt werden können. Dazu weist die Vorrichtung 21 eine Bohrmaschine 22 mit einem Bohrer 23 und eine Spritzvorrichtung 24 für die Dichtungsmasse 11 mit einer Spritzdüse 25 auf, welche Spritzdüse 25 in die von dem Bohrer 23 der Bohrmaschine 22 gefertigte Lochung 9 paßt. Dabei ist die Spritzdüse 25 ein zylindrischer Körper, an dessen Außenseite die Austrittsöffnungen 26 für das Spritzgut, also die Dichtungsmasse 11, etwa radial angeordnet sind und dessen beidseitig dieser Austrittsöffnungen 26 befindlichen Endbereiche 27 als Verschluß der Bohrungen in den Rahmenstegen 7 und 8 dienen.5 shows a device designated as a whole by 21, with which the frame 3 can be produced and in particular the transverse perforations 9 and their inner wall can be produced. For this purpose, the device 21 has a drill 22 with a drill 23 and a spray device 24 for the sealing compound 11 with a spray nozzle 25, which spray nozzle 25 fits into the hole 9 made by the drill 23 of the drill 22. The spray nozzle 25 is a cylindrical body, on the outside of which the outlet openings 26 for the material to be sprayed, that is to say the sealing compound 11, are arranged approximately radially and on both sides of this outlet Openings 26 located end areas 27 serve as a closure of the holes in the frame webs 7 and 8.

Im Ausführungsbeispiel ist vorgesehen, daß Bohrer 23 und Spritzdüse 25 an einem gemeinsamen Maschinengestell 28 miteinander fluchtend, aber mit einem Abstand zwischen sich angeordnet sind, in den das Profil des Rahmens 3 - wie in Fig. 5 angedeutet - paßt, so daß der Bohrer 23 von der einen Seite durch das Profil und die Spritzdüse 25 danach von der entgegengesetzten Seite in das gebohrte Profil einführbar sind. Dabei weist die Spritzvorrichtung 24 in nicht näher dargestellter Weise eine beliebige Dosiereinrichtung für das Spritzgut auf, damit die richtige Menge gemäß den Fig. 2 bis 4 eingespritzt wird. Somit kann bei der Herstellung eines Rahmens 3 aus Hohlprofilen, welche mit Trockenmittel 12 gefüllt sind, zur -Herstellung quer verlaufendeYLochungen 9 so verfahren werden, daß zuerst die Lochung 9 in den Rahmen 3 gebohrt und nach Zurückziehung des Bohrers 23 der Zwischenraum zwischen den gelochten Stegen 7 und 8 des Rahmenprofiles um den Bohrungsbereich herum mit Dichtungsmasse 11 ausgespritzt wird. In vorteilhafter Weise dichtet dabei die Spritzdüse 25 die Lochungen in den Stegen 7 und 8 selbst ab. Gleichzeitig wird beim Einspritzen der Dichtungsmasse 11 die Innenwand der Lochung 9 etwa fluchtend mit den Bohrungsrändern in den Profilstegen 7 und 8 von der Spritzdüse 25 geformt. Während des Bohrens durch den Rahmen 3 kann austretendes Trockenmittel 12 abgesaugt wer- den. Dadurch entsteht gleichzeitig der Platz für die Dichtungsmasse 11 in dem Hohlprofil.In the exemplary embodiment it is provided that the drill 23 and the spray nozzle 25 are aligned with one another on a common machine frame 28, but are arranged at a distance between them, into which the profile of the frame 3 - as indicated in FIG. 5 - fits, so that the drill 23 are then insertable from one side through the profile and the spray nozzle 25 from the opposite side into the drilled profile. In this case, the spraying device 24 has any metering device for the sprayed material, so that the correct amount is injected according to FIGS. 2 to 4. Thus, in the manufacture of a frame 3 from hollow profiles, which are filled with desiccant 12, transverse holes 9 can be produced so that the holes 9 are first drilled into the frame 3 and, after the drill 23 has been withdrawn, the space between the perforated webs 7 and 8 of the frame profile around the bore area is sprayed with sealant 11. In an advantageous manner, the spray nozzle 25 seals the perforations in the webs 7 and 8 itself. At the same time, when the sealant 11 is injected, the inner wall of the perforation 9 is formed by the spray nozzle 25 approximately flush with the bore edges in the profile webs 7 and 8. During drilling through the frame 3 exiting desiccant 12 aspirated who - the. This creates the space for the sealant 11 in the hollow profile.
