Description

Die Erfindung bezieht sich auf einen Steckverbinder mit U- oder kastenförmigem Querschnitt, der als Gerad-, Winkel-, Eck- oder Kreuzungsverbinder ausgebildet ist, für Abstandhalterhohlprofile für Isolierglasscheiben mit einem Bodenteil und zwei Längsseitenkanten, die als vom Boden aufragende Schenkel ausgebildet sein können, wobei das Bodenteil zusammen mit den Längsseitenkanten den Körper des Verbinders bildet, wobei an den Längsseitenkanten nach außen ragende, elastisch verformbare Lamellen für jeden Einsteckabschnitt angeordnet sein können, die geneigt oder gebogen ausgeführt sein können, wobei die Neigung oder Biegung in Einsteckrichtung nach hinten ausgebildet sein kann.
Derartige Steckverbinder sind seit langem üblich und für viele Hohlprofile aus Stahl, Aluminium und Kunststoff gebräuchlich.The invention relates to a connector with U- or box-shaped cross section, which is designed as a straight, angled, corner or crossing connector, for spacer hollow profiles for insulating glass with a bottom part and two longitudinal side edges, which may be formed as upstanding leg, wherein the bottom part together with the longitudinal side edges forms the body of the connector, wherein on the longitudinal side edges outwardly projecting, elastically deformable lamellae can be arranged for each male portion, which can be made inclined or bent, wherein the inclination or bending are formed in the insertion direction to the rear can.
Such connectors have long been common and common for many hollow sections of steel, aluminum and plastic.

Beispiele aus dem Stand der Technik werden von US2009/107085 und DE29918002U gezeigt.Examples of the prior art are of US2009 / 107085 and DE29918002U shown.

Diese Hohlprofile sind meistens aus Flachmaterial hergestellt und in Längsrichtung geschweisst. Die Schweißnaht wurde bislang auf der späteren Außenseite des Hohlprofiles angeordnet, die durch Butyl oder dergleichen versiegelt wurde und so nicht mehr sichtbar war.These hollow sections are usually made of flat material and welded longitudinally. The weld was previously placed on the later outer side of the hollow profile, which was sealed by butyl or the like and so was no longer visible.

Gerade aber bei Sprossenprofilen aber auch bei normalen Abstandhalterhohlprofilen ist eine solche Anordnung der Schweißnaht nicht erwünscht, da dort beide Seiten des Profils sichtbar sind.
Deswegen wurde teilweise dazu übergegangen, die Hohlprofile an den Schmalseitenkanten zu schweißen und so die Schweißnaht in einen kaum sichtbaren Bereich zu verlegen.
Damit besteht aber das Problem, daß bekannte Steckverbinder für Hohlprofile nur noch eingeschränkt eingesetzt werden können. Entweder steigen die Einsteckkräfte stark an oder aber es ist kein sicherer Halt des Steckverbinders im Hohlprofil mehr gewährleistet.
Daher liegt der Erfindung die Aufgabe zugrunde, einen Steckverbinder vorzuschlagen, der einerseits leicht in ein solches neuartiges Hohlprofil einsetzbar ist, aber dennoch straff und sicher darin sitzt. Zudem soll der Steckverbinder auch für herkömmliche Hohlprofile einsetzbar sein.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an den Lamellen und/oder den Schenkeln Ausnehmungen vorgesehen sind, wobei die Ausnehmungen zusammen einen in Verbinderlängsrichtung weisenden Kanal bilden. Mittels dieser Ausnehmungen können die Lamellen bzw. Schenkel die Schweißnaht umgreifen. Die Ausnehmungen sorgen so dafür, daß die Lamellen bzw. Schenkel trotzdem an den Wandungen des Hohlprofiles anliegen und sich dort abstützen können. Dabei hat es sich als sehr vorteilhaft erwiesen, wenn die Ausnehmungen an den von den Schenkeln wegweisenden Enden der Lamellen bzw. den Außenseiten der Schenkel vorgesehen sind.
Dies entspricht der üblichen Anordnung der Schweißnaht bei den neuartigen Hohlprofilen.But especially in sprout profiles but also in normal spacer hollow profiles such an arrangement of the weld is not desirable because both sides of the profile are visible there.
For this reason, it has sometimes been decided to weld the hollow sections to the narrow side edges, thus laying the weld in a barely visible area.
But this is the problem that known connectors for hollow sections can only be used to a limited extent. Either the insertion forces increase sharply or else there is no longer any secure hold of the connector in the hollow profile.
The invention is therefore based on the object to propose a connector that is on the one hand easy to use in such a novel hollow profile, but still taut and safe sitting in it. In addition, the connector should also be used for conventional hollow sections.
This object is achieved in that recesses are provided on the blades and / or the legs, wherein the recesses together form a pointing in the connector longitudinal channel. By means of these recesses, the slats or legs can embrace the weld. The recesses ensure so that the slats or legs still rest against the walls of the hollow section and can be supported there. It has proved to be very advantageous if the recesses are provided at the pointing away from the legs ends of the slats or the outer sides of the legs.
This corresponds to the usual arrangement of the weld in the novel hollow sections.

Als äußerst vorteilhaft hat es sich erfindungsgemäß auch erwiesen, wenn die Ausnehmungen wenigstens annähernd teilkreisförmig oder rechteckig ausgebildet sind.It has also proven to be extremely advantageous according to the invention if the recesses are at least approximately part-circular or rectangular.

Damit wird die Schweißnaht optimal umfasst. Unnötig große Ausnehmungen werden vermieden.This optimally covers the weld. Unnecessarily large recesses are avoided.

Eine weitere sehr vorteilhafte Ausgestaltung der Erfindung liegt auch vor, wenn an den vom Bodenteil wegweisenden Enden der Schenkel Erhebungen vorgesehen sind, die als Auflaufschrägen und/oder Rastnasen ausgebildet sein können. Diese Rastnasen können sich auch auf einen Teil der Außenseite der Schenkel erstrecken.A further very advantageous embodiment of the invention is also provided when elevations are provided at the ends of the legs pointing away from the bottom part, which can be formed as run-on slopes and / or latching noses. These locking lugs can also extend to a part of the outside of the legs.

Durch diese Erhebungen wird ein zusätzlicher und damit verbesserter Halt des Steckverbinders im Hohlprofil sichergestellt.These surveys ensure an additional and thus improved hold of the connector in the hollow profile.

Gemäß einer weiteren Fortbildung der Erfindung ist es auch sehr vorteilhaft, wenn an der von den Schenkeln wegweisenden Seite des Bodenteils Erhebungen vorgesehen sind, die als Auflaufschrägen und/oder Rastnasen ausgebildet sein können und dabei wenigstens einen Teil der Breite des Bodenteils einnehmen können.According to a further development of the invention, it is also very advantageous if projections are provided on the side facing away from the legs of the bottom part, which can be formed as chamfers and / or locking lugs and thereby occupy at least part of the width of the bottom part.

Auch hierdurch wird der Halt des Steckverbinders im Hohlprofil verbessert.This also improves the hold of the connector in the hollow profile.

Erfindungsgemäß sehr vorteilhaft ist es auch, wenn wenigstens ein Anschlag vorgesehen ist, der die Einstecklänge des Steckverbinders in ein Hohlprofil zu begrenzen vermag, wobei die Anschläge an den Längsseitenkanten des Steckverbinders angeordnet und elastisch ausgebildet sein können.According to the invention it is also very advantageous if at least one stop is provided, which is able to limit the insertion length of the connector in a hollow profile, wherein the stops can be arranged on the longitudinal side edges of the connector and formed elastically.

Damit wird sichergestellt, daß der Steckverbinder nicht zu tief in ein Hohlprofilende eingesteckt wird. Dies ist gerade beim maschinellen Vorstecken äußerst wichtig.This ensures that the connector is not inserted too deeply into a hollow profile end. This is extremely important when it comes to machine pointing.

Dabei hat es sich als sehr vorteilhaft erwiesen, wenn ein Ausgleichselement im Bereich der Anschläge vorgesehen ist, welches federnd ausgebildet sein kann. Damit wird eine unerwünschte Kippbewegung des Steckverbinders im Hohlprofil vermieden. Zudem wird der Steckverbinder im Bereich der Anschläge zentriert.It has proven to be very advantageous if a compensating element is provided in the region of the stops, which may be resilient. This avoids undesirable tilting movement of the connector in the hollow profile. In addition, the connector is centered in the area of the stops.

Die Ausnehmungen bilden zusammen einen in Verbinderlängsrichtung weisenden Kanal, der für jede Einsteckrichtung getrennt ausgebildet sein kann.
Damit kann die erhabene Schweißnaht in die Ausnehmungen und den durch diese gebildeten Kanal eingreifen.
Sehr vorteilhaft ist es gemäß einer weiteren Ausgestaltung der Erfindung auch, wenn in den Ausnehmungen Erhebungen bzw. Überhöhungen vorgesehen sind, die als Rastnasen dienen können und dabei auch als Auflaufschrägen ausgebildet sein können. Diese Erhebungen bzw. Überhöhungen können sich an der Schweißnaht abstützen und sich an Unebenheiten derselben verhaken.
Ebenfalls sehr vorteilhaft ist es erfindungsgemäß auch, wenn die Ausnehmungen asymmetrisch in Verbinderhöhenrichtung und/oder in Verbinderlängsrichtung ausgebildet sind.
Auch mit einer solchen Ausgestaltung wird erreicht, daß sich die Ausnehmungen an der Schweißnaht abstützen bzw. verhaken können.
Im folgenden wird die Erfindung anhand eines Ausführungsbeispiels veranschaulicht. Dabei zeigen:

The recesses together form a channel extending in the connector longitudinal direction, which can be formed separately for each insertion direction.
Thus, the raised weld can engage in the recesses and the channel formed by them.
According to a further embodiment of the invention, it is also very advantageous if elevations or elevations are provided in the recesses which can serve as latching lugs and can also be formed as chamfers. These elevations or elevations may be supported on the weld and hooked on bumps thereof.
It is also very advantageous according to the invention if the recesses are formed asymmetrically in the connector height direction and / or in the connector longitudinal direction.
Even with such a configuration it is achieved that the recesses can be supported or hooked to the weld.
In the following the invention is illustrated by means of an embodiment. Showing:

Mit 1 ist in Fig. 1 ein U-förmiger Steckverbinder mit einem Bodenteil 2 und zwei an den Längsseitenkanten 3 und 4 anschließenden Längsseitenstegen 5 und 6 bezeichnet.With 1 is in Fig. 1 a U-shaped connector with a bottom part 2 and two adjoining the longitudinal side edges 3 and 4 longitudinal side webs 5 and 6 respectively.

An den Außenseiten der Längsseitenstege 5 und 6 sind nach außen ragende, in Einsteckrichtung nach hinten weisende Lamellen 7 angeordnet, die sich elastisch verformen können und sich damit an das jeweilige Hohlprofil anzupassen vermögen. Die Lamellen 7 verkeilen sich an den Innenseiten des jeweiligen Hohlprofiles und verhindern so, daß der Steckverbinder aus dem Hohlprofil versehentlich herausgezogen wird.On the outer sides of the longitudinal side webs 5 and 6 are outwardly projecting, arranged in the insertion towards the rear slats 7, which can deform elastically and thus able to adapt to the respective hollow profile. The fins 7 wedged on the inner sides of the respective hollow profile and thus prevent the connector from the hollow profile is accidentally pulled out.

Im Bereich der Mitte des Verbinders 1 sind ebenfalls an den Außenseiten der Längsseitenstege 5 und 6 für jede Einsteckrichtung jeweils ein Mittenanschlag 8 vorgesehen, der die Einstecktiefe des Verbinders 1 in die Hohlprofile begrenzt.In the area of the center of the connector 1, a center stop 8 is likewise provided on the outer sides of the longitudinal side webs 5 and 6 for each insertion direction, which limits the insertion depth of the connector 1 into the hollow profiles.

Den Mittenanschlägen 8 ist jeweils ein Ausgleichselement 9 zugeordnet, das gegenüber den Mittenanschlägen 8 jeweils am anderen Längsseitensteg 5 und 6 vorgesehen ist.The center stops 8 are each assigned a compensation element 9, which is provided opposite the center stops 8 on the other longitudinal side web 5 and 6 respectively.

Das Ausgleichselement 9 und sorgt einerseits dafür, daß die Hohlprofile gegen die Mittenanschläge 8 stoßen und kann federnd ausgebildet sein. Andererseits werden etwaige Fertigungstoleranzen des Hohlprofils ausgeglichen. Ein Wackeln des Verbinders 1 im Hohlprofil wird vermieden. Es ist aber auch denkbar, daß auf das Ausgleichselement 9 verzichtet werden kann.The compensation element 9 and on the one hand ensures that the hollow sections abut against the middle stops 8 and may be resilient. On the other hand compensated for any manufacturing tolerances of the hollow profile. A wobble of the connector 1 in the hollow profile is avoided. But it is also conceivable that can be dispensed with the compensation element 9.

Die nach außen ragenden Lamellen 7 können sich über einen Teil oder die gesamte Höhe der Seitenstege 5 bzw. 6 erstrecken. Am von den Seitenstegen weg weisenden Ende der Lamellen 7 sind Ausnehmungen 10 vorgesehen, die in diesem Ausführungsbeispiel etwa in der Mitte der Höhe der Lamellen 7 angeordnet und halbkreisförmig ausgebildet sind.The outwardly projecting slats 7 may extend over a part or the entire height of the side webs 5 and 6 respectively. At the side of the webs facing away from the end of the fins 7 recesses 10 are provided, which are arranged in this embodiment, approximately in the middle of the height of the fins 7 and formed semicircular.

Andere geometrische Ausgestaltungen der Ausnehmungen 10 sind denkbar. Diese können auch Teilkreise oder Ellipsoid-Abschnitte sein, oder aber auch geradlinige, rechteckige oder anderweitige Querschnitte aufweisen.Other geometric configurations of the recesses 10 are conceivable. These can also be pitch circles or ellipsoid sections, or else have rectilinear, rectangular or other cross sections.

In diese Ausnehmungen 10 kann eine nach innen ragende Schweißnaht am Hohlprofil eingreifen. Neben der Schweißnaht und damit neben den Ausnehmungen 10 stützen sich die Lamellen 7 an der Wandung ab und sorgen dafür, daß der Steckverbinder 1 nicht aus dem Hohlprofil versehentlich herausgezogen wird.In these recesses 10 can engage an inwardly projecting weld on the hollow profile. In addition to the weld and thus next to the recesses 10, the slats 7 are supported on the wall and ensure that the connector 1 is not accidentally pulled out of the hollow section.

Zusätzlich können in den Ausnehmungen 10 nicht dargestellte Erhebungen vorgesehen sein, die sich ihrerseits an der Schweißnaht des Hohlprofiles abzustützen vermögen. Dabei können die Erhebungen als in Einsteckrichtung geneigte Auflaufschrägen ausgebildet sein, um ein leichteres Einschieben des Steckverbinders 1 in das Hohlprofil sicherzustellen. Andererseits wird dadurch dann sichergestellt, daß sich die Auflaufschrägen auch sehr gut an selbst kleinsten Unebenheiten der Schweißnaht verhaken können und so ein unerwünschtes Herausziehen des Steckverbinders aus einem Hohlprofil verhindern.In addition, not shown elevations may be provided in the recesses 10, which in turn are able to support the weld of the hollow section. In this case, the elevations may be formed as inclined in the insertion direction bevels, to ensure easier insertion of the connector 1 in the hollow profile. On the other hand, it is then ensured that the run-on slopes can also very well catch on even the smallest bumps in the weld and thus prevent unwanted pulling out of the connector from a hollow profile.

Es ist aber auch denkbar, daß die Ausnehmungen 10 selbst abgeschrägt ausgeführt sind und sich schon auf diese Art und Weise an der Schweißnaht verhaken können.But it is also conceivable that the recesses 10 are made even beveled and can already get caught in this way at the weld.

Mehrere Ausnehmungen 10 hintereinander können einen wenigstens annähernd geradlinig verlaufenden Kanal bilden, in den die Schweißnaht eingeführt werden kann. Dabei ist es aber auch denkbar, daß der Kanal von der Verbinderlängsrichtung abweicht und so eine zusätzliche Verklemmung an der Schweißnaht erzeugt. Auch ist es denkbar, daß der Kanal geschwungen oder wenigstens gebogen verläuft und so dasselbe Ergebnis erzeugt. Dabei können die Ausnehmungen 10 auch entsprechend angeschrägt sein, um ein leichtes Aufschieben und einen festen Halt zu gewährleisten.A plurality of recesses 10 in a row can form an at least approximately rectilinear channel, in which the weld can be introduced. However, it is also conceivable that the channel deviates from the connector longitudinal direction and thus generates an additional jamming at the weld. It is also conceivable that the channel is curved or at least bent and so produces the same result. In this case, the recesses 10 can also be chamfered accordingly to ensure easy sliding and a firm grip.

Die Lamellen 7 sind im abgebildeten Beispiel entgegen der Einsteckrichtung des Steckverbinders 1 ins Hohlprofil nach hinten geneigt. Besonders gute Ergebnisse in Bezug auf die aufzuwendende Einsteckkraft und die aufzuwendende Kraft um die Verbinder wieder aus dem Hohlprofil herauszuziehen wurden bei Neigungen zwischen 30 und 60° erzielt. Andere Neigungswinkel sind denkbar.The slats 7 are inclined in the illustrated example opposite to the insertion of the connector 1 into the hollow profile to the rear. Particularly good results in terms of the insertion force to be applied and the force required to pull out the connectors again from the hollow profile were achieved at inclinations between 30 and 60 °. Other angles of inclination are conceivable.

Auch denkbar ist eine gebogene oder geschwungene Ausgestaltung der Lamellen 7.Also conceivable is a curved or curved configuration of the slats 7.

Die Lamellen 7 sind elastisch ausgebildet und können jede für sich genommen relativ leicht umgeformt werden. Um einen hinreichenden Halt des Verbinders im Hohlprofil sicherzustellen ist eine Vielzahl von Lamellen 7 vorgesehen.The fins 7 are elastic and can each be relatively easily formed by itself. In order to ensure a sufficient hold of the connector in the hollow profile, a plurality of fins 7 is provided.

Die Lamellen 7 im dargestellten Beispiel reichen in Höhenrichtung nur über einen Teil der Höhe des Hohlprofiles.The fins 7 in the illustrated example extend in height direction only over part of the height of the hollow section.

Die meisten Hohlprofile weisen im Bereich der Lamellen 7 eine sogenannte Butylsicke auf, in der beim Zusammensetzen einer Isolierglasscheibe Butyl eingebracht wird, das eine Klebung zwischen Abstandhalterhohlprofil und Scheibe herstellt.In the region of the lamellae 7, most of the hollow sections have a so-called butyl bead, in which butyl is introduced during the assembly of an insulating glass pane, which produces an adhesive bond between the spacer hollow profile and the pane.

Gerade im Bereich der Butylsicke können Rastelemente 12 vorgesehen sein, da dort das Hohlprofil eine sehr große Steifigkeit aufweist.Just in the field of butyl bead locking elements 12 may be provided, since there the hollow profile has a very high rigidity.

Viele Hohlprofile werden mit einem Trockenmittel gefüllt, um über einen langen Zeitraum zu gewährleisten, daß sich keine Feuchtigkeitsniederschläge in den Isolierglasscheiben bilden.Many hollow sections are filled with a desiccant to ensure over a long period of time that no moisture precipitates form in the insulating glass panes.

Dieses Trockenmittel soll nicht bis zur Stoßkante der zu verbindenden Hohlprofilenden gelangen, da dort die Gefahr besteht, daß das Trockenmittel in den Scheibeninnenraum austritt und dort für Verunreinigungen sorgt, die unerwünscht sind.This desiccant should not get to the abutting edge of the hollow profile ends to be joined, since there is the danger that the desiccant exits into the disc interior and there provides impurities that are undesirable.

Um zu vermeiden, daß das Trockenmittel bis zu dieser Stoßstelle zu gelangen vermag können einzelne Lamellen 7 als Sperrlamellen 7a ausgebildet werden, die gegenüber den restlichen Lamellen 7 überhöht ausgebildet sind und eine Kontur aufweisen, die an die Innenkontur des Hohlprofiles angepasst ist. Die Sperrlamellen 7a können auch zusätzlich zu den Lamellen 7 vorgesehen werden. Um eine gute Abdichtung zu gewährleisten ist für jeden Seitensteg und für jede Einsteckrichtung mindestens eine Sperrlamelle 7a vorgesehen.In order to avoid that the desiccant can reach up to this joint can single lamellae 7 are formed as locking lamellae 7a, which are formed over the remaining lamellae 7 excessive and have a contour which is adapted to the inner contour of the hollow profile. The locking lamellae 7a can also be provided in addition to the lamellae 7. In order to ensure a good seal at least one barrier plate 7a is provided for each side bar and for each insertion.

Zusätzlich können zwischen den Seitenstegen 5 und 6 quer verlaufende Sperrlamellen 11 vorgesehen werden. Durch diese Sperrlamellen 11 wird ein Trockenmitteldurchlauf durch den Steckverbinder 1 unterbunden. Auch im Mittenbereich kann damit kein Trockenmittel mehr an die Stoßstelle der Hohlprofilenden gelangen.In addition, between the side bars 5 and 6 transverse locking slats 11 are provided. Through this barrier slats 11 a desiccant pass through the connector 1 is prevented. Even in the middle area can thus no more desiccant reach the joint of the hollow profile ends.

Es hat sich dabei als sehr praktikabel erwiesen, wenn pro Einsteckrichtung des Steckverbinders wenigstens zwei Sperrlamellen 11 vorgesehen werden, da dann auch bei einem versehentlichen, geringfügigen Herausziehen des Steckverbinders 1 beim Handhaben von bereits fertiggestellten Abstandhalterrahmen ein unerwünschtes Austreten von Trockenmittel verhindert wird.It has proved to be very practical if at least two locking lamellae 11 are provided per plug-in direction of the connector, since then even with an accidental, slight withdrawal of the connector 1 when handling already completed spacer frame unwanted leakage of desiccant is prevented.

Dieses unerwünschte geringfügige Herausziehen des Steckverbinders 1 tritt oftmals bei als Eck- oder Winkelverbinder ausgebildeten Steckverbindern 1 auf.This unwanted slight withdrawal of the connector 1 often occurs when designed as a corner or angle connector connectors 1.

Die Seitenstege 5 und 6 können zusätzlich noch auf ihrer von der Bodenfläche 2 abgewandten Seite Rastnasen 12 tragen, die als Auflaufschrägen in Einsteckrichtung des Steckverbinders ausgebildet sein können.The side bars 5 and 6 may additionally still carry on their side facing away from the bottom surface 2 side locking lugs 12 which may be formed as chamfers in the insertion direction of the connector.

Auch auf der von den Seitenstegen 5 und 6 wegweisenden Oberfläche der Bodenfläche 2 können Rastnasen 13 vorgesehen sein, die ebenfalls als Auflaufschrägen ausgebildet sein können. Diese Rastnasen 13 können sich an der entsprechenden Innenseite des Hohlprofiles abstützen und dort schon an kleinsten Unebenheiten verkrallen. Es ist auch denkbar, daß sich die Rastnasen 13 an Perforationsbuckeln abstützen, die in das Hohlprofil eingebracht wurden, um Feuchtigkeit in das mit einem Molekularsieb gefüllte Hohlprofil eintreten zu lassen.Also on the side of the webs 5 and 6 pioneering surface of the bottom surface 2 locking lugs 13 may be provided, which may also be formed as chamfers. These locking lugs 13 can be supported on the corresponding inner side of the hollow profile and dig there even the smallest bumps. It is also conceivable that the locking lugs 13 are supported on Perforationsbuckeln, which were introduced into the hollow section to allow moisture to enter the filled with a molecular sieve hollow section.

Die Enden des Steckverbinders 1 können abgeschrägt ausgebildet sein, um das Einstecken in die Hohlprofilenden zu erleichtern. Ein maschinelles Vorstecken oder auch Einstecken wird so unterstützt.The ends of the connector 1 may be formed chamfered to facilitate insertion into the hollow profile ends. A machine plugging or plugging is supported.

Durch das Zusammenwirken aller vorgenannten Merkmale wird ein universell einsetzbarer Steckverbinder geschaffen, der als Gerad-, Winkel-, Kreuz- oder Eckverbinder für Abstandhalterhohlprofile aber auch für Sprossen, Sprossenkreuze oder dergleichen einsetzbar ist.Due to the interaction of all the aforementioned features, a universally applicable connector is created, which can be used as a straight, angled, cross or corner connector for spacer hollow profiles but also for rungs, cross bars or the like.

Zwischenstücke zwischen den beiden Einsteckschenkeln sind denkbar, die beispielsweise ein Eck oder einen Winkel ausformen und an den Querschnitt des jeweiligen Hohlprofiles angepasst sein können.Intermediate pieces between the two Einsteckschenkeln are conceivable, for example, form a corner or an angle and can be adapted to the cross section of the respective hollow profile.

Der erfindungsgemäße Steckverbinder kann bei allen Arten von Hohlprofilen eingesetzt werden. Denkbar ist der Einsatz bei Aluminium-, Stahl-, Edelstahl-, aber auch Kunststoff-Profilen, vor allem aber bei Profilen, die an wenigstens einer Seitenkante eine nach innen ragende Schweißnaht aufweisen.The connector according to the invention can be used in all types of hollow profiles. Conceivable is the use in aluminum, steel, stainless steel, but also plastic profiles, but especially in profiles that have at least one side edge inwardly projecting weld.

Der Einsatz der Steckverbinder 1 ist bei allen Formaten von Isolierglasscheiben denkbar. Die Rückhaltekraft ist auch für große Schaufensterscheiben mit großen Abmessungen ausreichend. Auch bei der Herstellung solcher, oftmals mehrere Meter großer Scheiben werden die Abstandhalterhohlprofilenden sicher gehalten.
Die Ausnehmungen 10 können symmetrisch am Steckverbinder 1 verteilt angeordnet sein, so daß dieser in beliebiger Einsteckrichtung eingesetzt werden kann. Es ist aber auch denkbar, durch die Anordnung der Ausnehmungen 10 eine vorgegebene Einsteckrichtung und Passung zu bestimmten Hohlprofilen zu definieren.
Wie in Fig. 4 dargestellt können die Ausnehmungen 10 auch direkt in den Längsseitenstegen 5 und 6 angeordnet werden, wobei dann auf Lamellen 7 verzichtet wird. Der dort dargestellte Steckverbinder ist mit 21 bezeichnet.
Gerade bei diesem Ausführungsbeispiel können, wie in Fig.5 dargestellt, die auf der Unterseite der Bodenfläche 2 angeordneten Rastelemente 13 wenigstens annähernd die volle Breite des Steckverbinders 21 einnehmen. Zusätzlich können an den Außenkanten der Bodenfläche 2 Gleitflächen 22 vorgesehen sein, die ein leichteres Einschieben des Steckverbinders in das jeweilige Hohlprofil ermöglichen. Der Halt des Steckverbinders 21 wird dadurch nicht negativ beeinflusst.The use of the connector 1 is conceivable in all formats of insulating glass panes. The retention force is also sufficient for large display windows with large dimensions. Even in the production of such, often several meters large slices, the spacer hollow profile ends are held securely.
The recesses 10 may be arranged distributed symmetrically on the connector 1, so that it can be used in any direction of insertion. However, it is also conceivable to define a predetermined insertion direction and fit to specific hollow profiles by the arrangement of the recesses 10.
As in Fig. 4 the recesses 10 can also be arranged directly in the longitudinal side webs 5 and 6, in which case slats 7 are dispensed with. The connector shown there is designated 21.
Especially in this embodiment, as in Figure 5 illustrated, the arranged on the bottom of the bottom surface 2 locking elements 13 occupy at least approximately the full width of the connector 21. In addition, 2 sliding surfaces 22 may be provided on the outer edges of the bottom surface, which allow easier insertion of the connector into the respective hollow profile. The hold of the connector 21 is not adversely affected.
