Weitere Einzelheiten der Erfindung ergeben sich aus der nachstehenden Beschreibung eines Ausführungsbeispieles der Erfindung. Es zeigt: Fig. 1 in Stirnansicht eine als Sichelscheibe ausgebildete Isolierglasscheibe und Fig. 2 einen Schnitt längs der Linie II-II in Fig. 1.Further details of the invention emerge from the following Description of an embodiment of the invention. It 1 shows a front view of a crescent disk Insulating glass pane and Fig. 2 shows a section along the line II-II in Fig. 1.

Die in Fig. 1 gezeigte Isolierglasscheibe 1 besteht aus einer ebenen Glasscheibe 2 und einer nach einer Richtung gewölbten, zweiten Glasscheibe 3, die miteinander über einen Abstandhalterrahmen verbunden sind. Im Bereich der beiden zueinander parallel verlaufenden Ränder 4 und 5, (die senkrecht zur Bildebene von Fig. 1 verlaufenden Ränder) der Isolierglasscheibe 1 können übliche Hohlprofilleisten als Teile (Schenkel) des Abstandhalterrahmens vorgesehen sein.The insulating glass pane 1 shown in Fig. 1 consists of a flat Glass pane 2 and a second arched in one direction Glass pane 3, which are connected to one another via a spacer frame are. In the area of the two parallel to each other Edges 4 and 5 (which are perpendicular to the image plane of FIG. 1 Edges) of the insulating glass pane 1 can be conventional hollow profile strips be provided as parts (legs) of the spacer frame.

Wie in Fig. 1 gezeigt, weist der Abstandhalterrahmen im Bereich der Ränder der als Sichelscheibe ausgebildeten Isolierglasscheibe 1, an denen die Ränder der Glasscheiben 2 und 3 nicht parallel zueinander verlaufen, also einen sich über die Länge dieses Randes ändernden Abstand voneinander aufweisen, einen erfindungsgemäßen Abstandhalter 10 auf.As shown in Fig. 1, the spacer frame has in the range of Edges of the insulating glass pane 1 designed as a sickle pane which the edges of the glass panes 2 and 3 are not parallel to each other run, i.e. a changing over the length of this edge Have a distance from each other, a spacer according to the invention 10 on.

Der erfindungsgemäße Abstandhalter 10 besteht aus einer vorzugsweise einstückig hergestellten Profilleiste aus Metall oder Kunststoff, wobei Aluminium oder eine Aluminiumlegierung, die durch Strangpressen zur Profilleiste geformt wurde, der Vorzug gegeben wird.The spacer 10 according to the invention preferably consists of a one-piece profile strip made of metal or plastic, being aluminum or an aluminum alloy made by extrusion was formed into a profile bar, preference is given.

Die Profilleiste besitzt einen Hohlprofilteil 11 mit zwei zu den Scheiben parallelen Wänden 12, 13, zwei zu den Glasscheiben 2, 3 senkrechten Wänden 14, 15 und einen Hohlraum 16, in dem Trockenmittel aufgenommen werden kann. Das Trockenmittel entfaltet seine Wirkung durch in der dem Innenraum 6 der Isolierglasscheibe 1 zugekehrten Wand 15 des Hohlprofilteils 11 vorgesehene Öffnungen 17. Von der Wand 13 des Hohlprofilteils 11 des Abstandhalters 10 gemäß der Erfindung steht ein über die gesamte Länge des Abstandhalters 10 durchgehender Steg 20 ab.The profile strip has a hollow profile part 11 with two to Panels parallel walls 12, 13, two to the glass panes 2, 3rd vertical walls 14, 15 and a cavity 16 in the desiccant can be included. The desiccant unfolds its Effect by facing the interior 6 of the insulating glass pane 1 Wall 15 of the hollow profile part 11 provided openings 17th According to the wall 13 of the hollow profile part 11 of the spacer 10 the invention stands over the entire length of the spacer 10 continuous web 20 from.

Vor dem Bearbeiten des Abstandhalters 10 hat der Steg 20 bevorzugt über seine gesamte Länge eine gleichmäßige Breite. So besteht die Möglichkeit, durch abtragendes Bearbeiten des freien Randes 21 des Steges 20, diesem Rand 21 eine Kontur zu geben, die der Form der Innenfläche 7 der beispielsweise nach einer Richtung gewölbten zweiten Glasscheibe 3, die in der Regel die im Einbauzustand äußere Glasscheibe 3 der Isolierglasscheibe 1 sein wird, zu geben.Before processing the spacer 10, the web 20 has preferred A uniform width over its entire length. So there is Possibility, by machining the free edge 21 of the Web 20, this edge 21 to give a contour that the shape of Inner surface 7 of, for example, curved in one direction second glass pane 3, which is usually the outer one in the installed state Glass pane 3 will be the insulating glass pane 1.

Es ist ersichtlich, daß durch das abtragende Bearbeiten des Steges 20 im Bereich seines Randes 21 die Kontur des freien Randes 21 dieses Steges 20 in eine weitgehend beliebige Form gebracht werden kann. Durch das abtragende Bearbeiten (Schleifen, Schneiden oder Stanzen) wird die jeweils gewünschte Form des Steges 20 erreicht.It can be seen that by machining the web 20 in the region of its edge 21, the contour of the free edge 21 this web 20 can be brought into a largely arbitrary shape can. By ablation processing (grinding, cutting or Stamping) the desired shape of the web 20 is achieved.

Wenn eine größere Serie von Isolierglasscheiben 1 hergestellt werden sollen, die übereinstimmend gewölbte Glasscheiben 2 und/oder 3 besitzen, ist es möglich, Abstandhalter 10 in Serie herzustellen, deren Steg 20 einen entsprechend konturierten Außenrand 21 besitzt. Dies kann beispielsweise dadurch erfolgen, daß die Abstandhalter 10 nach dem Ablängen von der Hohlprofilleiste auf die erforderliche Länge unmittelbar durch Schleifen, Stanzen, Sägen oder Abschneiden die erforderliche Außenkontur seines Steges 20 erhält.When a larger series of insulating glass panes 1 are manufactured should have correspondingly curved glass panes 2 and / or 3, it is possible to produce spacers 10 in series, whose web 20 has a correspondingly contoured outer edge 21. This can be done, for example, by the spacers 10 after cutting to length from the hollow profile strip to the required Length directly by grinding, punching, sawing or cutting receives the required outer contour of its web 20.

Wenn Isolierglasscheiben mit zwei nicht ebenen, also gewölbten Glasscheiben 2 und 3 hergestellt werden, dann kann ein Abstandhalter 10 in Form einer Hohlprofilleiste verwendet werden, die zwei vom Hohlprofilteil 11 des Abstandhalters 10 abstehende Stege 20 aufweist, die vorzugsweise in derselben Ebene angeordnet sind. Bevorzugt ist dabei - ebenso wie bei der Ausführungsform des Abstandhalters 10 gemäß Fig. 2, daß die dem Innenraum 6 der Isolierglasscheibe 1 zugekehrte Fläche 23 des Steges 20 und die dem Innenraum 6 zugewendete Fläche 24 der Wand 15 des Hohlprofilteils 11 in ein und derselben Ebene liegen.When insulating glass panes with two non-flat, i.e. curved ones Glass panes 2 and 3 are made, then a spacer 10 can be used in the form of a hollow profile strip, the two from Hollow profile part 11 of the spacer 10 has projecting webs 20, which are preferably arranged in the same plane. Prefers is there - just like in the embodiment of the spacer 10 that the interior 6 of the insulating glass pane 1 facing surface 23 of the web 20 and the interior 6 facing Surface 24 of the wall 15 of the hollow profile part 11 in and are on the same level.
