Description

Die Erfindung betrifft ein Verfahren zur Herstellung einer Isolierglasscheibe mit wenigstens zwei durch einen Abstandhalterrahmen voneinander getrennten Glasscheiben.The invention relates to a method for producing an insulating glass pane with at least two glass panes separated from one another by a spacer frame.

Ferner betrifft die folgende Offenlegung auch eine Isolierglasscheibe mit zwei durch einen aus Rahmenschenkeln gebildeten Abstandhalterrahmen voneinander getrennten Glasscheiben.The following disclosure also relates to an insulating glass pane with two glass panes separated from one another by a spacer frame formed from frame legs.

Derartige Verfahren und Isolierglasscheiben sind aus dem Stand der Technik in unterschiedlichen Ausführungsformen bekannt.Such methods and insulating glass panes are known from the prior art in different embodiments.

So ist beispielsweise aus der Druckschrift WO 2016/156492 A1 ein Verfahren zum Verbinden von Metallabschnitten eines Abstandhalterrahmens vorbekannt, bei dem eine Metallverbindung verwendet wird. Die Metallverbindung wird in die Andruckzone zwischen Enden zweier miteinander zu verbindender Metallabschnitte eingebracht. Anschließend wird die Andruckzone auf eine Temperatur erhitzt, die in einem Bereich liegt, der größer ist als die Liquidustemperatur der Metallverbindung und niedriger als die Solidustemperatur der miteinander zu verbindenden Metallabschnitte. Die Temperatur wird in diesem Temperaturbereich solange gehalten, bis die zwischen den Metallabschnitten eingeklemmte Metallverbindung vollständig aufgeschmolzen ist. Danach werden die Metallabschnitte abgekühlt, damit sich die Metallverbindung verfestigt und einen die Metallabschnitte verbindenden Metallwulst bildet.For example, from the publication WO 2016/156492 A1 a method for connecting metal sections of a spacer frame is previously known, in which a metal connection is used. The metal connection is introduced into the pressure zone between the ends of two metal sections to be connected to one another. The pressure zone is then heated to a temperature which is in a range which is greater than the liquidus temperature of the metal compound and lower than the solidus temperature of the metal sections to be joined together. The temperature is kept in this temperature range until the metal connection clamped between the metal sections has completely melted. The metal sections are then cooled so that the metal connection solidifies and forms a metal bead connecting the metal sections.

Je nach konkreter Ausführungsform des Herstellungsverfahrens ist dabei ein beträchtlicher manueller Aufwand nötig, der insbesondere die automatisierte Herstellung von solchen Isolierglasscheiben erschwert und verteuert. Aufgabe der Erfindung ist es daher, ein Verfahren der eingangs genannten Art zu schaffen, bei denen diese Nachteile vermieden werden können.Depending on the specific embodiment of the manufacturing process, considerable manual effort is required, which in particular makes the automated manufacture of such insulating glass panes more difficult and expensive. The object of the invention is therefore to create a method of the type mentioned at the outset in which these disadvantages can be avoided.

Erfindungsgemäß wird diese Aufgabe durch ein Verfahren zur Herstellung einer Isolierglasscheibe mit den Mitteln und Merkmalen des Anspruchs 1 gelöst. Zur Lösung der Aufgabe wird insbesondere ein Verfahren zur Herstellung einer Isolierglasscheibe mit wenigstens zwei durch einen Abstandhalterrahmen voneinander getrennten Glasscheiben vorgeschlagen, bei dem noch miteinander unverbundene Rahmenschenkel des Abstandhalterrahmes der herzustellenden Isolierglasscheibe auf einer ersten Glasscheibe der Isolierglasscheibe positioniert und beim Positionieren und/oder nach dem Positionieren auf der ersten Glasscheibe ohne Verwendung von Eckverbindern zu dem Abstandhalterrahmen miteinander verbunden werden.According to the invention, this object is achieved by a method for producing an insulating glass pane with the means and features of claim 1. To achieve the object, a method for producing an insulating glass pane with at least two glass panes separated from one another by a spacer frame is proposed in which the still unconnected frame legs of the spacer frame of the insulating glass pane to be produced are positioned on a first glass pane of the insulating glass pane and during positioning and / or after positioning on the first pane of glass without using corner connectors to form the spacer frame.

Im Vergleich zu den aus dem Stand der Technik vorbekannten Verfahren zur Herstellung von Isolierglasscheiben ist das erfindungsgemäße Verfahren zur Herstellung einer Isolierglasscheibe damit deutlich vereinfacht. Während bei einigen, aus dem Stand der Technik vorbekannten Verfahren, vorgefertigte Abstandhalterrahmen an die Stelle der endgültigen Montage der Isolierglasscheibe transportiert werden müssen, kann dieser Aufwand bei dem erfindungsgemäßen Verfahren vermieden werden. Aufgrund der vergleichsweise fragilen Konstruktion der Abstandhalterrahmen, die für derartige Isolierglasscheiben verwendet werden, ist vor allem der Transport vormontierter oder vorgefertigter Abstandhalterrahmen, insbesondere dann, wenn die Abstandhalterrahmen große Dimensionen haben, vergleichsweise schwierig. Auch aus materialwirtschaftlicher Sicht kann das erfindungsgemäße Verfahren Vorteile bieten. So ist es möglich, an einer Station, an der die Isolierglasscheibe hergestellt wird, entsprechend vorkonfektionierte Rahmenschenkel bereitzuhalten. Da die aus Rahmenschenkeln zusammengesetzten Abstandhalterrahmen erst beim Positionieren oder nach dem Positionieren der Rahmenschenkel auf der ersten Glasscheibe einer Isolierglasscheibe und unmittelbar vor der endgültigen Montage der herzustellenden Isolierglasscheibe zu dem Abstandhalterrahmen aus den noch unverbundenen Rahmenschenkeln zusammengesetzt werden, wird das Risiko einer Beschädigung bereits vorgefertigter Abstandhalterrahmen, die bei einem Transport der Abstandhalterrahmen auftreten könnte, vermieden.In comparison to the methods for producing insulating glass panes known from the prior art, the method according to the invention for producing an insulating glass pane is thus significantly simplified. While in some methods known from the prior art, prefabricated spacer frames have to be transported to the place of the final assembly of the insulating glass pane, this effort can be avoided with the method according to the invention. Due to the comparatively fragile construction of the spacer frames that are used for such insulating glass panes, the transport of pre-assembled or prefabricated spacer frames is comparatively difficult, especially when the spacer frames are large. The method according to the invention can also offer advantages from a material management point of view. It is thus possible to have appropriately prefabricated frame legs ready at a station where the insulating glass pane is produced. Since the spacer frame, which is composed of frame legs, is only used when positioning or after positioning the frame legs on the first Glass pane of an insulating glass pane and immediately before the final assembly of the insulating glass pane to be produced to form the spacer frame from the still unconnected frame legs, the risk of damage to already prefabricated spacer frames, which could occur when the spacer frames are transported, is avoided.

Besonders stabile Abstandhalterrahmen lassen sich auf einer ersten Glasscheibe der Isolierglasscheibe herstellen, wenn als Rahmenschenkel biegestarre Rahmenschenkel verwendet werden. Die Rahmenschenkel können dabei aus einem biegestarren Hohlprofil hergestellt sein.Particularly stable spacer frames can be produced on a first glass pane of the insulating glass pane if rigid frame legs are used as the frame legs. The frame legs can be made from a rigid hollow profile.

Bevor die noch unverbundenen Rahmenschenkel auf der ersten Glasscheibe der Isolierglasscheibe positioniert werden, können die Rahmenschenkel an ihren den Glasscheiben der Isolierglasscheibe, zwischen denen sie angeordnet werden, zugewandten Seitenflächen mit einer Verbindungsmasse versehen werden. Bei dieser Verbindungsmasse kann es sich insbesondere um Butyl, um einen adhäsiven Dichtstoff oder auch um einen Kleber handeln. Es ist auch möglich, solche Rahmenschenkel bei dem Verfahren zur Herstellung einer Isolierglasscheibe zu verwenden, die bereits an den Seitenflächen mit einer derartigen Verbindungsmasse versehen, insbesondere mit einer solchen beschichtet sind. Mit Hilfe der Verbindungsmasse, die an den Seitenflächen der Rahmenschenkel angeordnet ist, können die Rahmenschenkel dann an der ersten Glasscheibe befestigt werden. Wird nach Fertigstellung des Abstandhalterrahmens aus ursprünglich noch unverbundenen Rahmenschenkeln eine zweite Glasscheibe der Isolierglasscheibe auf den so hergestellten Abstandhalterrahmen aufgelegt, können die den Abstandhalterrahmen bildenden Rahmenschenkel über die an der anderen Seitenfläche angeordnete Verbindungsmasse, die auch eine Dichtmasse sein kann, mit der zweiten Glasscheibe der Isolierglasscheibe verbunden und an dieser befestigt werden.Before the still unconnected frame legs are positioned on the first glass pane of the insulating glass pane, the frame legs can be provided with a bonding compound on their side faces facing the glass panes of the insulating glass pane between which they are arranged. This bonding compound can in particular be butyl, an adhesive sealant, or an adhesive. It is also possible to use such frame legs in the method for producing an insulating glass pane which are already provided with such a bonding compound on the side surfaces, in particular are coated with such a compound. With the help of the connecting compound which is arranged on the side surfaces of the frame legs, the frame legs can then be attached to the first glass pane. If, after completion of the spacer frame from originally unconnected frame legs, a second glass pane of the insulating glass pane is placed on the spacer frame produced in this way, the frame legs forming the spacer frame can be connected to the connecting compound on the other side surface can be a sealing compound, connected to the second glass pane of the insulating glass pane and attached to it.

Die Rahmenschenkel können im Bereich einer rückseitigen, einem von dem Abstandhalterrahmen umgebenen Innenraum abgewandten Stoßkante zwischen zwei einander zugewandten Stirnenden benachbarter Rahmenschenkeln mit Hilfe einer Verbindungsmasse miteinander verbunden werden. Dies insbesondere nach ihrer Positionierung auf der Glasscheibe. Grundsätzlich ist es auch vorstellbar, diese rückseitige Verbindung zwischen den Rahmenschenkeln durch Auftrag einer Verbindungsmasse in diesem Bereich während dem Auflegen oder Positionieren der Rahmenschenkel des herzustellenden Abstandhalterrahmens auf der ersten Glasscheibe der Isolierglasscheibe herzustellen.The frame legs can be connected to one another with the aid of a bonding compound in the area of a rear abutting edge facing away from an interior space surrounded by the spacer frame, between two facing ends of adjacent frame legs. This especially after their positioning on the glass pane. In principle, it is also conceivable to establish this rear connection between the frame legs by applying a bonding compound in this area while the frame legs of the spacer frame to be produced are being placed or positioned on the first glass pane of the insulating glass pane.

Bei der verwendeten Verbindungsmasse kann es sich vorzugsweise um Butyl, um einen adhäsiven Dichtstoff und/oder um einen Kleber handeln. Die mittels Verbindungsmasse im Bereich der rückseitigen Stoßkanten zwischen zwei benachbarten Rahmenschenkeln hergestellte Verbindung kann dabei so ausgebildetsein, dass Außenecken des hergestellten Abstandhalterrahmens abgedichtet sind. Auf diese Weise kann die aufgetragene Verbindungsmasse nicht nur zur: Verbindung der einzelnen Rahmenschenkel untereinander dienen, sondern auch gleichzeitig die Funktion einer gasdichten Abdichtung des Abstandhalterrahmens im Bereich der Stoßkanten zwischen den: Rahmenschenkeln, und damit der Außenecken des Abstandhalterrahmens übernehmen. Zusammen mit der auf die Seitenflächen der Rahmenschenkel aufgetragenen Verbindungsmasse lässt sich der von dem Abstandhalterrahmen definierte Innenraum der Isolierglasscheibe nach Auflegen einer zweiten Glasscheibe auf den so hergestellten Abstandhalterrahmen gasdicht abdichten.The bonding compound used can preferably be butyl, an adhesive sealant and / or an adhesive. The connection established by means of connecting compound in the area of the rear abutting edges between two adjacent frame legs can be designed in such a way that outer corners of the spacer frame produced are sealed. In this way, the applied compound can not only serve to: connect the individual frame legs to one another, but also simultaneously function as a gas-tight seal for the spacer frame in the area of the abutting edges between the: frame legs and thus the outer corners of the spacer frame. Together with the bonding compound applied to the side surfaces of the frame legs, the interior of the insulating glass pane defined by the spacer frame can be sealed gas-tight after a second glass pane has been placed on the spacer frame produced in this way.

Es ist möglich, eine Verbindungsmasse jeweils an zumindest einem Stirnende eines Rahmenschenkels von zwei benachbarten Rahmenschenkeln aufzutragen. Dies insbesondere in Form einer Verbindungsmasseraupe, die beispielsweise aus Butyl, aus einem adhäsiven Dichtstoff und/oder auch Kleber bestehen kann. Danach können die beiden benachbarten Rahmenschenkel mit ihren einander zugewandten Stirnenden in Stoßstellung zueinander gebracht werden. Dadurch kann die auf den einen Rahmenschenkel stirnseitig aufgetragene Verbindungsmasse so verformt werden, dass eine, beispielsweise die bereits zuvor erwähnte rückseitige, einem von dem Abstandhalterrahmen umgebenen Innenraum abgewandte Stoßkante zwischen den beiden Rahmenschenkeln mit der Verbindungsmasse gasdicht abgedichtet und die beiden Rahmenschenkel miteinander verbunden werden. Dabei kann vorzugsweise der Rahmenschenkel, an dessen Stirnseite keine Verbindungsmasse aufgetragen ist, auf den Rahmenschenkel mit Verbindungsmasse an seiner Stirnseite zubewegt werden. Insbesondere dann, wenn der zu bewegende Rahmenschenkel auch an seinen Seitenflächen mit einer Verbindungsmasse beschichtet ist, kann es vorteilhaft sein, den Rahmenschenkel durch eine Kippbewegung beim Positionieren des Rahmenschenkels auf der ersten Glasscheibe der Isolierglasscheibe mit dem ihm benachbarten Rahmenschenkel in der zuvor beschriebenen Weise zu verbinden.It is possible to apply a bonding compound to at least one end face of a frame leg of two adjacent frame legs. This in particular in the form of a compound bead, which can consist of butyl, an adhesive sealant and / or glue, for example. Then the two adjacent frame legs can be brought into abutment position with their facing ends. As a result, the connecting compound applied to the end face of one frame leg can be deformed in such a way that a joint edge, for example the previously mentioned rear, facing away from an interior space surrounded by the spacer frame, is sealed gas-tight with the connecting compound and the two frame legs are connected to one another. In this case, the frame leg, on whose front side no connection compound is applied, can preferably be moved towards the frame leg with connection compound on its front side. In particular, when the side surfaces of the frame leg to be moved is coated with a bonding compound, it can be advantageous to connect the frame leg to the frame leg adjacent to it in the manner described above by means of a tilting movement when the frame leg is positioned on the first glass pane of the insulating glass pane .

Die Verbindungsmasse kann dabei über eine gesamte Länge eines rückseitigen Randes des Stirnendes des Rahmenschenkels aufgetragen werden. Auf diese Weise kann ausreichend Verbindungsmasse vorhanden sein, um die beim Zusammenführen der benachbarten Rahmenschenkel erzeugte rückseitige Stoßkante zwischen den Rahmenschenkeln, die dann auch eine Außenecke des Abstandhalterrahmens bildet, mit Verbindungsmasse abdecken zu können.The connecting compound can be applied over an entire length of a rear edge of the front end of the frame leg. In this way, sufficient connection compound can be present to be able to cover with connection compound the rear abutment edge between the frame legs which is produced when the adjacent frame legs are brought together and which then also forms an outer corner of the spacer frame.

Es ist aber auch möglich, eine Verbindungsmasse auf eine von dem Abstandhalterrahmen begrenzten Innenraum abgewandte, rückseitige Stoßkante zwischen zwei bereits auf der ersten Glasscheibe in ihrer Gebrauchsstellung vorpositionierten Rahmenschenkeln aufzubringen. Hierbei werden die Rahmenschenkel zunächst in eine Sollposition an der ersten Glasscheibe fixiert und anschließend die Verbindungsmasse aufgebracht.However, it is also possible to apply a bonding compound to an interior space that is facing away from the spacer frame and facing away from the rear abutting edge between two frame legs that are already prepositioned on the first glass pane in their position of use. Here, the frame legs are first fixed in a target position on the first glass pane and then the bonding compound is applied.

Dabei kann die Verbindungsmasse vorzugsweise in Form einer Verbindungsmasseraupe, die insbesondere aus Butyl und/oder einem adhäsiven Dichtstoff und/oder aus Kleber bestehen kann, aufgebracht werden. Nochmals sei betont, dass bei dieser Variante des erfindungsgemäßen Verfahrens die einzelnen Rahmenschenkel des herzustellenden Abstandhalterrahmens zunächst in ihre Gebrauchsstellung oder auch Sollstellung auf der ersten Glasscheibe des Abstandhalterrahmens vorpositioniert werden. Nachdem die Rahmenschenkel des Abstandhalterrahmens ihre Sollposition an der Glasscheibe eingenommen haben, wird dann die Verbindungsmasse in der zuvor beschriebenen Art und Weise an die rückseitigen Stoßkanten, die dann die Außenecken des herzustellenden Abstandhalterrahmens bilden, jeweils zwischen zwei benachbarten Rahmenschenkeln des Abstandhalterrahmens aufgetragen und die Rahmenschenkel so zu dem Abstandhalterrahmen miteinander verbunden.In this case, the bonding compound can preferably be applied in the form of a bonding compound bead, which can in particular consist of butyl and / or an adhesive sealant and / or adhesive. It should again be emphasized that in this variant of the method according to the invention, the individual frame legs of the spacer frame to be produced are initially pre-positioned in their use position or also in their desired position on the first glass pane of the spacer frame. After the frame legs of the spacer frame have assumed their desired position on the glass pane, the bonding compound is then applied in the manner described above to the rear abutting edges, which then form the outer corners of the spacer frame to be produced, between two adjacent frame legs of the spacer frame, and the frame legs like that connected to the spacer frame.

Die Verbindungsmasse kann dabei so auf die rückseitigen Stoßkanten zwischen den Rahmenschenkeln aufgebracht werden, dass die rückseitigen Stoßkanten vollständig abgedeckt sind. Es ist auch möglich, die aufgetragene Verbindungsmasse in eine im Bereich der rückseitigen Stoßkante vorhandene Ausnehmung und/oder einen zwischen den beiden Rahmenschenkeln dort vorhandenen Spalt zu drücken. Auf diese Weise kann die gewünschte Dichtwirkung, die von der Verbindungsmasse in diesem Bereich ebenfalls erzeugt werden soll, verbessert werden. Grundsätzlich kann es vorteilhaft sein, die auf die rückseitige Stoßkante aufgebrachte Verbindungsmasse nach ihrem Auftrag anzupressen und/oder zu verstreichen.The connecting compound can be applied to the rear joint edges between the frame legs in such a way that the rear joint edges are completely covered. It is also possible to press the applied bonding compound into a recess present in the area of the rear abutting edge and / or into a gap present there between the two frame legs. In this way, the desired sealing effect, which is also to be produced by the connecting compound in this area, can be improved. In principle, it can be advantageous to press and / or spread the bonding compound applied to the rear joint edge after it has been applied.

Stirnenden der Rahmenschenkel können, insbesondere bevor die. Rahmenschenkel auf der ersten Glasscheibe positioniert werden, mit einer Gehrung versehen, insbesondere auf Gehrung geschnitten oder gefräst werden. Um eine rückseitige Ausnehmung zwischen zwei in ihrer Gebrauchsstellung an dem Abstandhalterrahmen zueinander benachbarten Rahmenschenkeln zu erzeugen, können die mit einer Gehrung versehenen Stirnenden quer oder rechtwinklig zu einer Längsachse des jeweiligen Rahmenschenkels und durch die Gehrung hindurch gekappt werden. Dies kann beispielsweise durch Schneiden oder Fräsen der auf Gehrung gebrachten Stirnenden der Rahmenschenkel geschehen. Auf diese Weise wird also eine durch die Gehrung der Rahmenschenkel im Bereich ihrer Stirnenden erzeugten Spitze der Rahmenschenkel abgenommen, so dass sich eine quer oder rechtwinklig zur Längsachse des jeweiligen Rahmenschenkels orientierte Stirnfläche ausbildet. Werden die derartig gekappten Rahmenschenkel in Stoßstellung zueinander gebracht, entsteht im Bereich ihrer dann gedachten: rückseitigen Stoßkante zwischen zwei benachbarten Rahmenschenkeln jeweils eine Ausnehmung. Die gedachte rückseitige Stoßkante kann sich dort befinden, wo sich Ebenen schneiden, in denen dem Innenraum des Abstandhalterrahmens abgewandten Rückseiten der benachbarten Rahmenschenkel angeordnet sind. In diese in jeder der Außenecken des Abstandhalterrahmen so erzeugten Ausnehmungen kann die Verbindungsmasse beim Auftrag der Verbindungsmasse oder durch das Verpressen der aufgetragenen Verbindungsmasse eingebracht werden kann. Ein besonderer Vorteil dieser rückseitigen Ausnehmungen im Bereich der Außenecken des Abstandhalterrahmens kann darin gesehen werden, dass die auf die Seitenflächen der Rahmenschenkel aufgetragene Verbindungsmasse und die im Bereich der rückseitigen Stoßkanten zwischen den Rahmenschenkeln aufgetragene Verbindungsmasse an dieser Stelle ineinander übergehen können. So kann die durch den Auftrag der Verbindungsmasse ebenfalls gewünschte Dichtwirkung insbesondere in diesem Bereich verbessert werden.Front ends of the frame legs can, especially before the. Frame legs are positioned on the first glass pane, provided with a miter, in particular cut or milled with a miter. In order to create a rear recess between two frame legs adjacent to one another in their position of use on the spacer frame, the mitered front ends can be cut across or at right angles to a longitudinal axis of the respective frame leg and through the miter. This can be done for example by cutting or milling the mitered front ends of the frame legs. In this way, a tip of the frame legs produced by the miter of the frame legs in the area of their front ends is removed, so that an end face oriented transversely or at right angles to the longitudinal axis of the respective frame leg is formed. If the frame legs capped in this way are brought into abutment position with respect to one another, a recess is created in the area of their then imagined: rear abutment edge between two adjacent frame legs. The imaginary rear abutting edge can be located where planes intersect in which rear sides of the adjacent frame legs facing away from the interior of the spacer frame are arranged. The connecting compound can be introduced into these recesses thus generated in each of the outer corners of the spacer frame when the connecting compound is applied or by pressing the applied connecting compound. A particular advantage of these rear recesses in the area of the outer corners of the spacer frame can be seen in that the connection compound applied to the side surfaces of the frame legs and the connection compound applied between the frame legs in the area of the rear abutting edges can merge into one another at this point. In this way, the sealing effect, which is also desired by applying the bonding compound, can be improved, particularly in this area.

In zumindest einem Rahmenschenkel des Abstandhalterrahmens der herzustellenden Isolierglasscheibe kann ein Trockenmittel eingebracht werden. Dabei kann der Rahmenschenkel nach Einbringen des Trockenmittels stirnseitig mit einem Verbindungsmassepropfen verschlossen werden. Die hier verwendete Verbindungsmasse kann dieselbe sein, wie sie an den Seitenflächen oder an den rückseitigen Stoßkanten zwischen zwei Rahmenschenkeln verwendet wird.A drying agent can be introduced into at least one frame leg of the spacer frame of the insulating glass pane to be produced. After the desiccant has been introduced, the frame limb can be closed at the end with a connecting mass plug. The connecting compound used here can be the same as that used on the side surfaces or on the rear abutting edges between two frame legs.

Ferner ist es möglich, eine dem Innenraum des Abstandhalterrahmens abgewandte, quer zu den Seitenflächen orientierte Außenseite des Abstandhalterrahmens mit einem Sekundärdichtstoff zu versehen. Als Sekundärdichtstoff kann ein Klebstoff oder auch eine Sekundärversiegelung verwendet werden. Der Auftrag des Sekundärdichtstoffs kann vorzugsweise nach Anbringen einer zweiten Glasscheibe an dem Abstandhalterrahmen erfolgen.It is also possible to provide an outside of the spacer frame facing away from the interior of the spacer frame and oriented transversely to the side surfaces with a secondary sealant. An adhesive or a secondary seal can be used as the secondary sealant. The secondary sealant can preferably be applied after a second glass pane has been attached to the spacer frame.

Zur Lösung der Aufgabe ist bei einer Isolierglasscheibe der eingangs genannten Art vorgesehen, dass die Rahmenschenkel zur Bildung des Abstandhalterrahmens mittels Verbindungsmasse an den Glasscheiben befestigt und mittels Verbindungsmasse und ohne Verwendung von Eckverbindern miteinander verbunden sind.To achieve the object, it is provided for an insulating glass pane of the type mentioned at the outset that the frame legs to form the spacer frame are fastened to the glass panes by means of connecting compound and are connected to one another by means of connecting compound and without using corner connectors.

Auf diese Weise wird eine Isolierglasscheibe geschaffen, deren Abstandhalterrahmen sich bei der Montage der Isolierglasscheibe fertigen lässt. Eine Handhabung eines bereits vorgefertigten oder vormontierten Abstandhalterrahmens kann auf diese Weise entfallen. Zudem ist bei der Isolierglasscheibe die Verwendung von Eckverbindern zum Verbinden der einzelnen Rahmenschenkel zu dem Abstandhalterrahmen nicht notwendig. Aufgrund der verwendeten Verbindungsmasse zur Befestigung der Rahmenschenkel an den Glasscheiben und zur Verbindung der Rahmenschenkel untereinander erhält der so erzeugte Abstandhalterrahmen auch ohne Eckverbinder eine ausreichende Stabilität.In this way, an insulating glass pane is created, the spacer frame of which can be manufactured during the assembly of the insulating glass pane. Handling of an already prefabricated or pre-assembled spacer frame can be dispensed with in this way. In addition, the use of corner connectors for connecting the individual frame legs to the spacer frame is not necessary with the insulating glass pane. Due to the connecting compound used to fasten the frame legs to the glass panes and to connect the frame legs to one another, the spacer frame thus produced is sufficiently stable even without a corner connector.

Vorzugsweise sind die verwendeten Rahmenschenkel biegestarre Rahmenschenkel. Als Verbindungsmasse kann Butyl, ein adhäsiver Dichtstoff und/oder auch Kleber verwendet werden. Die Verwendung von Butyl ist besonders vorteilhaft, da die Verbindungsmasse dann auch zum Abdichten der Isolierglasscheibe, genauer gesagt eines von dem Abstandhalterrahmen umgebenen Innenraums der Isolierglasscheibe verwendet werden kann. Vorteilhaft kann es sein, wenn Verbindungsmasse zwischen: Seitenflächen der Rahmenschenkel, die den Glasscheiben der Isolierglasscheibe zugewandt sind: und den Glasscheiben der Isolierglasscheibe aufgetragen ist. Ferner ist es möglich, Verbindungsmasse auch im Bereich von rückseitigen Stoßkanten zwischen in Gebrauchsstellung benachbarten Rahmenschenkeln aufzutragen. Die rückseitigen Stoßkanten zwischen den Rahmenschenkeln bilden Außenecken des Abstandhalterrahmens. Die Verbindungsmasse kann hier so aufgetragen sein, dass Außenecken des Abstandhalterrahmens vorzugsweise entlang der gesamten Länge der Stoßkanten abgedichtet sind. Wie bereits zuvor ausgeführt, kann so die aufgetragene Verbindungsmasse einerseits zur Befestigung der Rahmenschenkel untereinander und zur Befestigung der Rahmenschenkel an den Glasscheiben der Isolierglasscheibe und zum anderen zum Abdichten der Isolierglasscheibe verwendet werden.The frame legs used are preferably rigid frame legs. Butyl, an adhesive sealant and / or glue can be used as the bonding compound. The use of butyl is particularly advantageous since the bonding compound can then also be used to seal the insulating glass pane, more precisely an interior of the insulating glass pane surrounded by the spacer frame. It can be advantageous if connecting compound is applied between: side surfaces of the frame legs which face the glass panes of the insulating glass pane and the glass panes of the insulating glass pane. It is also possible to apply bonding compound in the area of the rear abutting edges between adjacent frame legs in the position of use. The rear edges between the frame legs form outside corners of the spacer frame. The bonding compound can be applied here in such a way that outer corners of the spacer frame are preferably sealed along the entire length of the abutting edges. As already stated above, the applied connecting compound can on the one hand for fastening the frame legs to one another and for fastening the frame legs to the glass panes of the insulating glass pane and on the other hand for sealing the insulating glass pane.

Die Verbindungsmasse, die zur Verbindung der Rahmenschenkel untereinander eingesetzt wird, kann auf Außenecken des Abstandhalterrahmens aufgetragen sein. Dafür kann: die Verbindungsmasse zwischen den Rahmenschenkeln jeweils auf eine rückseitige, eine von dem Abstandhalterrahmen definierten Innenraum abgewandte Stoßkante zwischen zwei benachbarten Rahmenschenkeln aufgetragen sein. Besonders vorteilhaft ist es, wenn die dort aufgetragene Dichtmasse nach dem Auftrag angepresst und/oder verstrichen ist.The connecting compound, which is used to connect the frame legs to one another, can be applied to outer corners of the spacer frame. For this purpose: the connecting compound between the frame legs can each be applied to a rear joint edge between two adjacent frame legs, facing away from an interior space defined by the spacer frame. It is particularly advantageous if the sealing compound applied there is pressed on and / or spread out after application.

Entlang einer, beispielsweise der zuvor erwähnten rückseitigen Stoßkante kann zwischen zwei benachbarten Rahmenschenkeln eine rückseitige, einem von dem Abstandhalterrahmen definierten Innenraum abgewandte Ausnehmung ausgebildet sein. In diese Ausnehmung kann Verbindungsmasse zur Verbindung der beiden Rahmenschenkel eingebracht werden oder sein. Besonders vorteilhaft: ist es, wenn die in die Ausnehmung eingebrachte Verbindungsmasse dabei in einem derartigen Umfang aufgetragen ist, dass sie sich mit einer auf die Seitenflächen der Rahmenschenkel aufgetragenen Verbindungsmasse ,verbinden kann. In diesem Zusammenhang kann es besonders vorteilhaft sein, wenn sich die rückseitige Ausnehmung über eine gesamte Breite der Rückseite der Rahmenschenkel erstreckt, also beispielsweise an ihren den Seitenflächen der Rahmenschenkel zugewandten Enden offen ausgebildet ist. So ist es möglich, dass auch ein Übergangsbereich zwischen der Stoßkante und den Seitenflächen der Rahmenschenkel mit Verbindungsmasse abgedeckt und abgedichtet ist. Die zuvor beschriebene Ausnehmung kann dann an nur einer Außenecke oder auch an jeder Außenecke des Abstandhalterrahmens ausgebildet sein.A rear recess facing away from an interior space defined by the spacer frame can be formed along one, for example the previously mentioned rear abutting edge between two adjacent frame legs. Connection compound for connecting the two frame legs can be introduced into this recess. It is particularly advantageous if the connection compound introduced into the recess is applied to such an extent that it can connect to a connection compound applied to the side surfaces of the frame legs. In this context, it can be particularly advantageous if the rear recess extends over an entire width of the rear side of the frame limbs, that is, for example, is designed to be open at its ends facing the side faces of the frame limbs. It is thus possible that a transition area between the abutting edge and the side surfaces of the frame legs is covered and sealed with bonding compound. The recess described above can then be formed on only one outside corner or on each outside corner of the spacer frame.

Die Rahmenschenkel können an ihren Stirnenden jeweils eine Gehrung aufweisen.The frame legs can each have a miter at their front ends.

Es ist auch möglich, dass die Rahmenschenkel an ihren Stirnenden jeweils eine Gehrung aufweisen, so dass sie sich gut miteinander zu dem Abstandhalterrahmen verbinden lassen. Es ist auch möglich, dass Rahmenschenkel an ihren Stirnenden eine Gehrung aufweisen und zur Erzeugung einer, beispielsweise der bereits zuvor erwähnten, rückseitigen Ausnehmung zwischen zwei in Gebrauchsstellung benachbarten Rahmenschenkeln eine quer zur Gehrung und quer zur Rückseite des jeweiligen Rahmenschenkels orientierte Stirnfläche aufweisen, die durch eine Rückseite des jeweiligen Rahmenschenkels begrenzt ist.It is also possible that the frame legs each have a miter at their front ends, so that they can be easily connected to one another to form the spacer frame. It is also possible that the frame legs have a miter at their front ends and, for example, the previously mentioned rear recess between two adjacent frame legs in the position of use, have an end face oriented transversely to the miter and transversely to the rear of the respective frame leg, which is Back of the respective frame leg is limited.

Die zuvor beschriebene Isolierglasscheibe ist nach dem erfindungsgemäßen Verfahren hergestellt.The insulating glass pane described above is produced by the method according to the invention.

Bei der nachfolgenden Beschreibung verschiedener Ausführungsformen der Erfindung erhalten in ihrer Funktion übereinstimmende Elemente auch bei abweichender Gestaltung oder Formgebung übereinstimmende Bezugszahlen.In the following description of various embodiments of the invention, elements that match in their function are given matching reference numbers even if they have a different design or shape.

Insbesondere die Figuren 1 und 2 zeigen eine im Ganzen mit 1 bezeichnete Isolierglasscheibe, die zumindest zwei durch einen aus Rahmenschenkeln 2 gebildeten Abstandhalterrahmen 3 voneinander getrennte Glasscheiben 4 aufweist. Von den beiden Glasscheiben 4 dieser Isolierglasscheibe ist nur eine erste Glasscheibe 4a dargestellt. Die Rahmenschenkel 2 sind zur Bildung des Abstandhalterrahmens 3 mittels Verbindungsmasse 5 an den Glasscheiben 4, 4a befestigt und mittels Verbindungsmasse 5 und ohne Verwendung von Eckverbindern miteinander verbunden.especially the Figures 1 and 2 show an insulating glass pane, designated as a whole by 1, which has at least two glass panes 4 separated from one another by a spacer frame 3 formed from frame legs 2. Of the two glass panes 4 of this insulating glass pane, only a first glass pane 4a is shown. To form the spacer frame 3, the frame legs 2 are fastened to the glass panes 4, 4a by means of connecting compound 5 and are connected to one another by means of connecting compound 5 and without the use of corner connectors.

Die Rahmenschenkel 2 sind biegestarre Rahmenschenkel 2. Als Dichtmasse 5 wird Butyl, ein adhäsiver Dichtstoff und/oder ein Kleber verwendet.The frame legs 2 are rigid frame legs 2. Butyl, an adhesive sealant and / or an adhesive is used as the sealing compound 5.

Insbesondere die Figuren 7 und 8 verdeutlichen, dass Verbindungsmasse 5 zwischen Seitenflächen 6 der einzelnen Rahmenschenkel 2 und den Glasscheiben 4, 4a aufgetragen ist. Die Seitenflächen 6 der Rahmenschenkel 2 sind diejenigen Seitenflächen, die den Glasscheiben 4, 4a der Isolierglasscheibe 1 zugewandt sind, wenn die Rahmenschenkel 2 ihre Gebrauchsstellung an den Glasscheiben 4, 4a eingenommen haben. Die Figuren 1, 3, 4 sowie 9 bis 12 verdeutlichen, dass Verbindungsmasse 5 auch im Bereich von Stoßkanten 7 zwischen in Gebrauchsstellung benachbarten Rahmenschenkeln 2 des Abstandhalterrahmens 3 aufgetragen ist. Die Verbindungsmasse ist so aufgetragen, dass Außenecken 8 des Abstandhalterrahmens 3 abgedichtet sind.especially the Figures 7 and 8 make it clear that connecting compound 5 is applied between side surfaces 6 of the individual frame legs 2 and the glass panes 4, 4a. The side surfaces 6 of the frame legs 2 are those side surfaces which face the glass panes 4, 4a of the insulating glass pane 1 when the frame legs 2 have assumed their position of use on the glass panes 4, 4a. The Figures 1 , 3, 4 and FIGS. 9 to 12 illustrate that the connecting compound 5 is also applied in the area of the abutting edges 7 between frame legs 2 of the spacer frame 3 that are adjacent in the position of use. The connection ground is like this applied that outer corners 8 of the spacer frame 3 are sealed.

Die Verbindungsmasse 5, die zur Verbindung der Rahmenschenkel 2 untereinander verwendet wird, ist jeweils in den Bereich einer rückseitigen, einem von dem Abstandhalterrahmen 3 definierten Innenraum 9 abgewandten Stoßkante 7 zwischen zwei benachbarten Rahmenschenkeln 2 aufgetragen. Wie die Figuren 9 bis 12 verdeutlichen, wird die Verbindungsmasse 5 nach ihrem Auftrag in den Bereich der Stoßkanten 7 angepresst und gegebenenfalls verstrichen. Dies kann, wie in Figur 9 dargestellt, beispielsweise mit einem Werkzeug 10 erfolgen.The connecting compound 5, which is used to connect the frame legs 2 to one another, is applied to the area of a rear joint edge 7 between two adjacent frame legs 2 facing away from an interior 9 defined by the spacer frame 3. As the Figures 9 to 12 To illustrate, the connecting compound 5 is pressed into the area of the abutting edges 7 after it has been applied and, if necessary, spread over. As in Figure 9 shown, for example with a tool 10.

Bei dem in den Figuren 9 und 10 dargestellten Ausführungsbeispiel eines Abstandhalterrahmens 3 an einer Isolierglasscheibe 1 ist zu erkennen, dass entlang der rückseitigen Stoßkante 7 zwischen zwei benachbarten Rahmenschenkeln 2 eine rückseitige, dem von dem Abstandhalterrahmen 3 definierten Innenraum 9 abgewandte Ausnehmung 11 ausgebildet ist. In diese Ausnehmung 11 ist die Verbindungsmasse zur Verbindung der beiden Rahmenschenkel 2 eingebracht. Die Ausnehmung 11 ist an ihren den Seitenflächen 6 der Rahmenschenkel 2 zugewandten Enden 12 randoffen ausgebildet. Ein Übergangsbereich 13 zwischen der Stoßkante 7 und den Seitenflächen 6 der Rahmenschenkel 2 ist mit Verbindungsmasse 5 abgedeckt. Einige der in den Figuren dargestellten Rahmenschenkel 2, beispielsweise der Rahmenschenkel 2 gemäß Figur 5, weisen an jeder ihrer Stirnenden 14 jeweils eine Gehrung 15 auf.The one in the Figures 9 and 10 The illustrated embodiment of a spacer frame 3 on an insulating glass pane 1 shows that a rear recess 11 facing away from the interior 9 defined by the spacer frame 3 is formed along the rear abutting edge 7 between two adjacent frame legs 2. The connecting compound for connecting the two frame legs 2 is introduced into this recess 11. The recess 11 is formed at its ends 12 facing the side surfaces 6 of the frame legs 2 with an open edge. A transition area 13 between the abutting edge 7 and the side surfaces 6 of the frame legs 2 is covered with bonding compound 5. Some of the frame legs 2 shown in the figures, for example the frame legs 2 according to FIG Figure 5 , each have a miter 15 on each of their front ends 14.

Andere Rahmenschenkel 2, beispielsweise der, der in Figur 6 dargestellt ist, oder auch die Rahmenschenkel 2, die in den Figuren 9 und 10 dargestellt sind, weisen an ihren Stirnenden 14 jeweils eine Gehrung 15 auf und sind zur Erzeugung der rückseitigen Ausnehmung 11 zwischen zwei benachbarten Rahmenschenkeln 12 mit einer quer zur Gehrung 15 und quer zur Rückseite 16 des jeweiligen Rahmenschenkels 2 orientierten Stirnfläche 17 versehen. Die Stirnflächen 17 dieser so gekappten Rahmenschenkel 2 werden jeweils durch die Rückseite 16 des jeweiligen Rahmenschenkels 2 begrenzt. Die Figuren 9 und 10 zeigen, wie zwei mit derartigen Stirnflächen 17 ausgestattete Rahmenschenkel 2 in Stoßstellung zueinander ausgerichtet sind. Hier wird deutlich, dass aufgrund der Stirnflächen 17 eine rückseitige Ausnehmung 11 zwischen den beiden Rahmenschenkeln 2 entsteht. In diese Ausnehmung 11 kann die Dichtmasse 5 eingepresst werden. Da die Ausnehmungen 11 randoffen ausgebildet sind, ist ein Übertritt der in die Ausnehmung 11 eingepressten Verbindungsmasse 5 in Richtung der Seitenflächen 6 der Rahmenschenkel 2 möglich, wo sich die: aus der jeweiligen Ausnehmung 11 ausgetretene Verbindungsmasse 5 mit der auf die Seitenflächen 6 aufgetragene Verbindungsmasse 5 verbinden kann. So lässt sich eine effektive Dichtfläche, die von der Verbindungsmasse 5 abgedeckt wird, maximieren.Other frame legs 2, for example the one in Figure 6 is shown, or the frame legs 2, which are in the Figures 9 and 10 are shown, each have a miter 15 at their front ends 14 and are used to generate the Rear recess 11 between two adjacent frame legs 12 is provided with an end face 17 oriented transversely to the miter 15 and transversely to the rear side 16 of the respective frame limb 2. The end faces 17 of these frame legs 2 capped in this way are each delimited by the rear side 16 of the respective frame leg 2. The Figures 9 and 10 show how two frame legs 2 equipped with such end faces 17 are aligned in abutment with one another. It becomes clear here that a rear recess 11 is created between the two frame legs 2 due to the end faces 17. The sealing compound 5 can be pressed into this recess 11. Since the recesses 11 are designed with an open edge, the connecting compound 5 pressed into the recess 11 can cross over in the direction of the side surfaces 6 of the frame legs 2, where the connecting compound 5 that has emerged from the respective recess 11 and the connecting compound 5 applied to the side surfaces 6 can connect. An effective sealing surface that is covered by the connecting compound 5 can thus be maximized.

Die zuvor beschriebene Isolierglasscheibe 1 wird mit dem nachfolgenden Verfahren hergestellt .The insulating glass pane 1 described above is produced using the following process.

Dabei ist vorgesehen, dass noch miteinander unverbundene Rahmenschenkel 2 des Abstandhalterrahmens 3 der Isolierglasscheibe 1 auf der ersten Glasscheibe 4a der Isolierglasscheibe 1 positioniert und beim Positionieren beziehungsweise nach dem Positionieren auf der ersten Glasscheibe 4a ohne Verwendung von Eckverbindern zu dem Abstandhalterrahmen 3 miteinander verbunden werden.It is provided that frame legs 2 of the spacer frame 3 of the insulating glass pane 1 that are still unconnected to one another are positioned on the first glass pane 4a of the insulating glass pane 1 and are connected to one another to form the spacer frame 3 during positioning or after positioning on the first glass pane 4a without the use of corner connectors.

Als Rahmenschenkel 2 werden biegestarre Rahmenschenkel 2 verwendet. Die Rahmenschenkel 2 werden an ihren den Glasscheiben 4, 4a, zwischen denen sie angeordnet werden, zugewandten Seitenflächen 6 mit einer Verbindungsmasse 5, hier mit Butyl, einem adhäsiven Dichtstoff und/oder mit Kleber versehen, beispielsweise bestrichen. Dies, bevor die Rahmenschenkel 2 auf der ersten Glasscheibe 4a positioniert werden. Die Rahmenschenkel 2 werden anschließend mit Hilfe der Verbindungsmasse 5 an der ersten Glasscheibe 4, 4a befestigt. Die Befestigung der Rahmenschenkel 2 an der ersten Glasscheibe 4a ist für die Stabilität des so erzeugten Abstandhalterrahmens 3 wichtig, da dieser gänzlich auf die Verwendung von Eckverbindern zur Verbindung der einzelnen Rahmenschenkel 2 verzichtet.Rigid frame legs 2 are used as frame legs 2. The frame legs 2 are on their the glass panes 4, 4a, between which they are arranged, facing side surfaces 6 with a bonding compound 5, here with butyl, an adhesive sealant and / or with adhesive, for example coated. This before the frame legs 2 are positioned on the first glass pane 4a. The frame legs 2 are then attached to the first glass pane 4, 4a with the aid of the connecting compound 5. The fastening of the frame legs 2 to the first glass pane 4a is important for the stability of the spacer frame 3 produced in this way, since this completely dispenses with the use of corner connectors to connect the individual frame legs 2.

Die Rahmenschenkel 2 werden mit Hilfe einer Verbindungsmasse 5 miteinander verbunden. Dies kann vorzugsweise nach Positionierung der Rahmenschenkel 2 auf der ersten Glasscheibe 4a oder auch bei ihrer Positionierung auf der ersten Glasscheibe 4a erfolgen. Dabei wird die Verbindungsmasse 5 jeweils im Bereich einer rückseitigen, dem von dem Abstandhalterrahmen 3 umgebenen Innenraum 9 abgewandten Stoßkante 7 zwischen zwei einander zugewandten Stirnenden 14 benachbarter Rahmenschenkel 2 aufgetragen. Die Stoßkanten 7 bilden nach erfolgter Herstellung des Abstandhalterrahmens 3 die Außenecken 8 des Abstandhalterrahmens 3. Der Auftrag der Verbindungsmasse erfolgt dabei insbesondere so, dass die Außenecken 8 des Abstandhalterrahmens 3 mit der Verbindungsmasse 5 abgedichtet sind.The frame legs 2 are connected to one another with the aid of a connecting mass 5. This can preferably take place after the frame legs 2 have been positioned on the first glass pane 4a or also when they are positioned on the first glass pane 4a. In this case, the connecting compound 5 is applied in the area of a rear abutting edge 7 facing away from the interior space 9 surrounded by the spacer frame 3 between two facing ends 14 of adjacent frame legs 2. After the spacer frame 3 has been produced, the abutting edges 7 form the outer corners 8 of the spacer frame 3. The connection compound is applied in particular such that the outer corners 8 of the spacer frame 3 are sealed with the connection compound 5.

Die Figuren 3 und 4 verdeutlichen, dass die Verbindungsmasse 5 in Form einer Verbindungsmasseraupe 5a jeweils an zumindest einem von zwei Stirnenden 14 eines von zwei benachbarten Rahmenschenkeln 2aufgetragen wird. Anschließend werden die beiden benachbarten Rahmenschenkel 2 mit ihren einander zugewandten Stirnenden 14 in Stoßstellung zueinander gebrachtThe Figures 3 and 4 It is clear that the connecting compound 5 in the form of a connecting compound bead 5a is applied to at least one of two front ends 14 of one of two adjacent frame legs 2. Subsequently, the two adjacent frame legs 2 are brought into abutment position with their facing ends 14

(vgl. Fig. 3 und 4). Dadurch wird die auf den einen Rahmenschenkel 2 aufgetragene Verbindungsmasse 5 so verformt, dass die rückseitige, dem Innenraum 9 abgewandte Stoßkante 7 zwischen den beiden Rahmenschenkeln 2 mit der Verbindungsmasse 5 abgedichtet und die beiden Rahmenschenkel 2 miteinander verbunden werden. Bei einer bevorzugten Ausführungsform des Verfahrens ist vorgesehen, dass der Rahmenschenkel 2, auf den keine Verbindungsmasse 5 an seinem Stirnende 14 aufgetragen ist, auf den Rahmenschenkel 2, der die Verbindungsmasse 5 in Form der Verbindungsmasseraupe 5a aufweist, zubewegt wird.(see. Figures 3 and 4 ). As a result, the connecting compound 5 applied to one frame limb 2 is deformed in such a way that the rear joint 7 facing away from the interior space 9 between the two frame limbs 2 is sealed with the connecting compound 5 and the two frame limbs 2 are connected to one another. In a preferred embodiment of the method it is provided that the frame leg 2, to which no connection compound 5 is applied at its end 14, is moved towards the frame leg 2, which has the connection compound 5 in the form of the connection compound bead 5a.

Bei einem anderen erfindungsgemäßen Verfahren ist vorgesehen, dass eine Verbindungsmasse 5, insbesondere in Form einer Verbindungsmasseraupe 5a auf eine von dem Abstandhalterrahmen 3 begrenzten Innenraum 9 abgewandte, rückseitige Stoßkante 7 zwischen zwei auf der ersten Glasscheibe 4a in ihrer Gebrauchsstellung vorpositionierten Rahmenschenkeln 2 aufgebracht wird. Dies mit dem Ziel, die beiden Rahmenschenkel 2 miteinander zu verbinden. Diese Vorgehensweise ist beispielsweise in den Figuren 9 und 10 dargestellt. Der Auftrag der Verbindungsmasse 5 auf die vorpositionierten Rahmenschenkel 2 erfolgt dabei derart, dass die rückseitige Stoßkante 7 zwischen den beiden Rahmenschenkeln 2 vollständig abdeckt und, wie in den Figuren 9 und 10 dargestellt, in eine im Bereich der rückseitigen Stoßkante 7 vorhandene Ausnehmung 11 beziehungsweise in einen zwischen den beiden Rahmenscherikeln 2 dort vorhandenen Spalt 18 (vgl. Fig. 11 und 12) gedrückt wird. So können die Außenecken 8 des Abstandhalterrahmens 3 zuverlässig abgedichtet werden.In another method according to the invention, it is provided that a bonding compound 5, in particular in the form of a bonding compound bead 5a, is applied to a rear abutting edge 7 facing away from the spacer frame 3, between two frame legs 2 prepositioned on the first glass pane 4a in their position of use. This with the aim of connecting the two frame legs 2 to one another. This procedure is for example in the Figures 9 and 10 shown. The application of the connecting compound 5 to the pre-positioned frame legs 2 takes place in such a way that the rear abutting edge 7 between the two frame legs 2 completely covers and, as in FIG Figures 9 and 10 shown, in a recess 11 present in the area of the rear abutting edge 7 or in a gap 18 present there between the two frame scissors 2 (cf. Figures 11 and 12 ) is pressed. The outer corners 8 of the spacer frame 3 can thus be reliably sealed.

Die Figuren 9 und 10 verdeutlichen, wie die auf die rückseitige Stoßkante 7 aufgebrachte Verbindungsmasse 5 nach ihrem Auftrag angepresst und/oder verstrichen wird. Dies erfolgt mit dem Werkzeug 10, das hier als Formstempel ausgebildet ist.The Figures 9 and 10 illustrate how the connecting compound 5 applied to the rear abutting edge 7 is pressed on and / or spread after it has been applied. This is done with the tool 10, which is designed here as a molding die is.

Die Stirnenden 14 der Rahmenschenkel 2, wie sie in den Figuren 4, 6 und 9 und 10 dargestellt sind, werden, bevor die Rahmenschenkel 2 auf der ersten Glasscheibe 4a positioniert werden, mit einer Gehrung 15 versehen. Die mit der Gehrung 15 versehenen Stirnenden 14 werden zur Erzeugung der rückseitigen Ausnehmung 11 zwischen den beiden in Gebrauchsstellung an dem Abstandhalterrahmen 3 benachbarten Rahmenschenkeln 2 quer oder rechtwinklig zu einer Längsachse des jeweiligen Rahmenschenkels 2 und durch die Gehrung 15 hindurch gekappt. Dies kann beispielsweise durch Schneiden oder Fräsen passieren. Ferner kann ein Trockenmittel 19 in zumindest einen der Rahmenschenkel 2 des Abstandhalterrahmens 3 eingebracht werden. Der Rahmenschenkel 2, der dann das Trockenmittel 19 aufweist, wird anschließend stirnseitig mit einem Verbindungsmassepropf 20 verschlossen.The front ends 14 of the frame legs 2, as they are in the Figures 4, 6 and 9 and 10 are shown, are provided with a miter 15 before the frame legs 2 are positioned on the first glass pane 4a. The front ends 14 provided with the miter 15 are cut transversely or at right angles to a longitudinal axis of the respective frame leg 2 and through the miter 15 between the two adjacent frame legs 2 in the position of use on the spacer frame 3 to create the rear recess 11. This can be done for example by cutting or milling. Furthermore, a desiccant 19 can be introduced into at least one of the frame legs 2 of the spacer frame 3. The frame leg 2, which then has the desiccant 19, is then closed on the front side with a compound plug 20.

Eine dem Innenraum 9 des Abstandhalterrahmens 3 abgewandte, quer zu den Seitenflächen 6 der Rahmenschenkel 2 orientierte Außenseite 21 des Abstandhalterrahmens 3 wird anschließend mit einem Sekundärdichtstoff 22 versiegelt. Diese Sekundärversiegelung aus Sekundärdichtstoff 22 ist beispielsweise in den Figuren 11 und 12 sowie in Figur 2 dargestellt.An outer side 21 of the spacer frame 3 facing away from the interior 9 of the spacer frame 3 and oriented transversely to the side surfaces 6 of the frame legs 2 is then sealed with a secondary sealant 22. This secondary seal made of secondary sealant 22 is for example in the Figures 11 and 12 as in Figure 2 shown.

Als Verbesserung auf dem technischen Gebiet der Isolierglasscheiben werden das erfindungsgemäße Verfahren zur Herstellung einer Isolierglasscheibe 1 sowie die Isolierglasscheibe 1 vorgeschlagen. Bei diesen ist vorgesehen, dass der Abstandhalterrahmen 3, der zwischen den Glasscheiben 4, 4a der Isolierglasscheibe 1 positioniert ist, beim Auflegen oder nach dem Auflegen einzelner, noch unverbundener Rahmenschenkel 2 auf eine erste Glasscheibe 4a der Isolierglasscheibe 1 hergestellt wird. Dazu werden die unverbundenen Rahmenschenkel 2 mittels einer Verbindungsmasse 5 einerseits mit den Glasscheiben 4, 4a und andererseits untereinander verbunden. Auf diese Weise kann auf die Verwendung von Eckverbindern, wie sie bereits aus dem Stand der Technik vorbekannten Isolierglasscheiben und ihren Abstandhalterrahmen bekannt sind, verzichtet werden.As an improvement in the technical field of insulating glass panes, the method according to the invention for producing an insulating glass pane 1 and the insulating glass pane 1 are proposed. In these it is provided that the spacer frame 3, which is positioned between the glass panes 4, 4a of the insulating glass pane 1, when placing or after placing individual, still unconnected frame legs 2 on a first glass pane 4a Insulating glass pane 1 is produced. For this purpose, the unconnected frame legs 2 are connected to the glass panes 4, 4a on the one hand and to one another on the other hand by means of a connecting compound 5. In this way it is possible to dispense with the use of corner connectors, as they are already known from the prior art insulating glass panes and their spacer frames.
