Description

Die Erfindung bezieht sich auf einen Steckverbinder aus Kunststoff zum Verbinden von Abstandhalter-Hohlprofilen aus insbesondere Metall, Kunststoff od. dgl. für Mehrscheibenisoliergläser.The invention relates to a connector made of plastic for connecting spacer hollow profiles of particular metal, plastic or the. Like. For multi-pane insulating.

Es sind eine Vielzahl von derartigen Steckverbindern bekannt, die jedoch oftmals den Nachteil aufweisen, nur schlecht in den Hohlprofilen zu halten. Gerade bei höheren Verarbeitungsgeschwindigkeiten sowie beim Biegen und Transportieren der Hohlprofile besteht die Gefahr, daß die Verbindungsstelle der Hohlprofile, die durch Steckverbinder zusammengehalten wird, sich öffnet und eventuell enthaltenes Trocknungsmittel austritt.There are a variety of such connectors known, but often have the disadvantage of poorly maintained in the hollow sections. Especially at higher processing speeds and when bending and transporting the hollow sections, there is the danger that the junction of the hollow profiles, which is held together by connectors, opens and any drying agent contained emerges.

Es sind Steckverbinder bekannt, die aufwendig durch Verstemmen in den Hohlprofilen befestigt werden. Durch diesen zusätzlichen Arbeitsschritt des Verstemmens ist jedoch nur noch ein verringerter Durchsatz bei der Verarbeitung der Hohlprofile möglich.There are known connectors that are attached by caulking in the hollow sections. By this additional step of caulking but only a reduced throughput in the processing of the hollow sections is possible.

Aus der EP 0 778 389 A1 ist beispielsweise ein Steckverbinder bekannt, der dieses Problem angeht, indem an den Längsseiten des Steckverbinders nach außen gerichtete Lamellen vorgesehen sind.From the EP 0 778 389 A1 For example, a connector is known which addresses this problem by providing on the longitudinal sides of the connector outwardly directed fins.

Aufgabe der Erfindung ist es, ausgehend von einem Steckverbinder, der an seinen Seiten mit nach außen gerichteten Lamellen versehen ist, derart auszugestalten, daß dieser auch unter widrigen Umständen sicher im Hohlprofil befestigt ist, ohne die Notwendigkeit eines zusätzlichen Arbeitsschrittes zu begründen.The object of the invention is, starting from a connector which is provided on its sides with outwardly directed lamellae, so designed that it is securely fixed even in adverse circumstances in the hollow section, without the need for an additional step to justify.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Lamellen einen im wesentlichen T-förmigen Querschnitt, senkrecht zur Längsebene des Steckverbinders gesehen, aufweisen, wobei die T-förmigen Lamellen aus einem Längssteg bestehen, der von der Außenseite der Verbinderlängsseite ausgeht und auf dem an seinem von der Verbinderlängsseite abgewandten Ende ein Quersteg ruht, der wenigstens annähernd parallel zur Verbinderlängsseite verläuft.This object is achieved in that the blades have a substantially T-shaped cross-section, seen perpendicular to the longitudinal plane of the connector, wherein the T-shaped blades consist of a longitudinal web extending from the outside of the connector longitudinal side and on the at his remote from the connector longitudinal end a transverse web rests, which extends at least approximately parallel to the connector longitudinal side.

Die Aussenseite jeder T-förmigen Lamelle vermag sich auf der Innenseite der Hohlprofile abzustützen und so ein versehentliches Herausziehen zu verhindern.The outside of each T-shaped lamella can support itself on the inside of the hollow profiles and thus prevent accidental withdrawal.

Es hat sich aber auch als sehr vorteilhaft erwiesen, wenn der Quersteg der Lamellen entgegen der Einsteckrichtung des Steckverbinders in das Hohlprofil nach hinten zum Steckverbinder hin geneigt ist.However, it has also proved to be very advantageous if the cross bar of the slats is inclined against the insertion of the connector in the hollow profile to the rear of the connector.

Dadurch wird das Einstecken des Verbinders in das Hohlprofil erleichtert und zudem noch das Herausziehen erschwert.As a result, the insertion of the connector is facilitated in the hollow profile and also makes it difficult to pull out.

Eine weitere sehr vorteilhafte Ausgestaltung der Erfindung liegt auch dann vor, wenn der Quersteg der Lamellen wenigstens annähernd der seitlichen Höhe des Hohlprofiles entspricht.Another very advantageous embodiment of the invention is also present when the transverse web of the lamellae corresponds at least approximately to the lateral height of the hollow profile.

Damit wird eine möglichst große Reibfläche zwischen Hohlprofil und Verbinder geschaffen.This creates the largest possible friction surface between the hollow profile and the connector.

Es hat sich erfindungsgemäß aber auch als sehr vorteilhaft erwiesen, wenn der Längssteg der Lamellen dieselbe oder eine geringere Höhe als der Quersteg aufweistIt has also proved to be very advantageous according to the invention when the longitudinal web of the lamellae has the same or a lower height than the transverse web

Ebenfalls sehr vorteilhaft ist es gemäß einer weiteren Ausgestaltung der Erfindung auch, wenn der Längssteg der Lamellen eine größere Höhe als der Quersteg aufweist.Likewise, it is also very advantageous according to a further embodiment of the invention, when the longitudinal web of the slats has a greater height than the transverse web.

Es hat sich auch als äußerst vorteilhaft erwiesen, wenn der Längssteg der Lamellen federnd ausgebildet ist.It has also proven to be extremely advantageous if the longitudinal web of the lamellae is resilient.

Durch unterschiedliche Höhen des Längssteges der Lamellen wird der Anpressdruck der Lamellen an der Innenseite des Hohlprofiles bestimmt. Je nach Profil und Größe kann dann ein entsprechender Steckverbinder eingesetzt werden, der einen an das Profil angepassten Anpressdruck seiner Lamellen aufweist. Durch eine federnde Ausgestaltung des Längssteges wird eine Anpassung und ein vollständiges Anliegen der Querstege am Hohlprofil sichergestellt.Due to different heights of the longitudinal web of the slats, the contact pressure of the slats is determined on the inside of the hollow section. Depending on the profile and size then a corresponding connector can be used, which has a matched to the profile contact pressure of its fins. By a resilient configuration of the longitudinal web an adaptation and complete concern of the transverse webs is ensured on the hollow profile.

Gemäß einer weiteren Ausgestaltung der Erfindung ist es auch sehr vorteilhaft, wenn der Quersteg der Lamellen federnd ausgebildet ist.According to a further embodiment of the invention, it is also very advantageous if the transverse web of the lamellae is resilient.

Hierdurch wird ebenfalls eine sehr gute Anpassung der Lamellen an das Hohlprofil erzielt. Der Steckverbinder lässt sich nur schwer aus dem Hohlprofil herausziehen.As a result, a very good adaptation of the slats is also achieved on the hollow profile. The connector is difficult to pull out of the hollow profile.

Es hat sich erfindungsgemäß auch als sehr vorteilhaft erwiesen, wenn Anschläge vorgesehen sind, die eine Einstecklänge in die zu verbindenden Hohlprofile vorgeben.It has also proved to be very advantageous according to the invention when stops are provided which predetermine a Einstecklänge in the hollow sections to be joined.

Sehr vorteilhaft ist es erfindungsgemäß auch, wenn die Anschläge im Bereich der Mitte der Längserstreckung des Verbinders angeordnet sind.It is also very advantageous according to the invention if the stops are arranged in the region of the middle of the longitudinal extension of the connector.

Dabei ist es äußerst vorteilhaft, wenn die Anschläge an den Außenseiten der Seitenstege vorgesehen sind.It is extremely advantageous if the stops are provided on the outer sides of the side bars.

Durch derartige Anschläge wird wirksam verhindert, daß der Verbinder in das Hohlprofil zu tief eingeschoben wird.By such stops effectively prevents the connector is inserted too deeply into the hollow profile.

Gemäß einer weiteren Ausgestaltung der Erfindung hat es sich auch als sehr vorteilhaft erwiesen, wenn ein federndes Ausgleichselement im Bereich der Anschläge vorgesehen ist.According to a further embodiment of the invention, it has also proved to be very advantageous if a resilient compensation element is provided in the region of the stops.

Damit wird ein ungewolltes Wackeln des Verbinders im Hohlprofil vermieden; Toleranzen werden ausgeglichen.This avoids unintentional wobbling of the connector in the hollow profile; Tolerances are compensated.

Erfindungsgemäß ist es sehr vorteilhaft, wenn der Steckverbinder als Winkel- oder Kreuzverbinder ausgebildet ist.According to the invention, it is very advantageous if the connector is designed as an angle or cross connector.

Ebenfalls sehr vorteilhaft ist es, wenn der Steckverbinder als Längsverbinder ausgebildet ist.It is also very advantageous if the connector is designed as a longitudinal connector.

Die erfindungsgemäße Verbinderausgestaltung lässt sich universell einsetzen.The connector design according to the invention can be used universally.

Eine weitere sehr vorteilhafte Ausgestaltung der Erfindung liegt auch dann vor, wenn der Steckverbinder als U-Verbinder mit einer Bodenfläche und zwei daran angeformten, in Längsrichtung verlaufenden Seitenstegen ausgebildet ist.Another very advantageous embodiment of the invention is also present when the connector is designed as a U-connector with a bottom surface and two molded thereon, extending in the longitudinal direction of the side webs.

Dadurch wird ein sehr stabiler und verwindungssteifer Verbinder geschaffen.This creates a very stable and torsionally stiff connector.

Sehr vorteilhaft ist es erfindungsgemäß auch, wenn die Bodenfläche wenigstens eine Durchbrechung aufweist.It is also very advantageous according to the invention if the bottom surface has at least one opening.

Damit wird Material eingespart, ohne die Stabilität des Verbinders negativ zu beeinflussen.This saves material without negatively affecting the stability of the connector.

Es hat sich gemäß einer weiteren Fortbildung der Erfindung auch als äußerst vorteilhaft erwiesen, wenn die Seitenstege wenigstens im oberen Bereich der Kontur des zu verbindenden Hohlprofils an dieses angepasst ausgebildet sind.It has also proved to be extremely advantageous according to a further development of the invention, when the side bars are formed adapted to this at least in the upper region of the contour of the hollow profile to be connected.

Hierdurch wird ein dichter Verschluß des Hohlprofiles geschaffen.As a result, a tight seal of the hollow section is created.

Eine weitere sehr vorteilhafte Ausgestaltung der Erfindung liegt auch dann vor, wenn die Seitenstege im oberen Bereich an der Außenseite abgeschrägt ausgebildet sind.Another very advantageous embodiment of the invention is also present when the side bars are formed bevelled in the upper region on the outside.

Durch eine derartige Abschrägung wird genügend Raum für Toleranzen des Hohlprofiles geschaffen.By such a chamfer enough space for tolerances of the hollow section is created.

Eine weitere äußerst vorteilhafte Ausgestaltung der Erfindung liegt auch dann vor, wenn die Seitenstege im oberen Bereich in der Steckverbindermitte eine Höhenverringerung aufweisen.Another extremely advantageous embodiment of the invention is also present when the side bars have a height reduction in the upper part of the connector center.

Hierdurch wird eine automatische Anpassung des Steckverbinders an Hohlprofile ermöglicht, die eine geringfügig zu geringe Innenhöhe aufweisen. Beim Einschieben wird an der Oberkante der Seitenstege ein Span gebildet, der im Bereich der Höhenverringerung nach innen abgeleitet wird und sich so nicht zwischen die Stoßkanten des Hohlprofiles klemmen kann.As a result, an automatic adjustment of the connector is made possible on hollow sections, which have a slightly too low internal height. When inserting a chip is formed on the upper edge of the side bars, which is derived in the region of the reduction in height to the inside and so can not pinch between the abutting edges of the hollow profile.

Im folgenden wird die Erfindung anhand eines Ausführunsgbeispiels veranschaulicht.In the following the invention is illustrated by means of an embodiment.

Mit 1 ist in Fig. 1 ein U-förmiger Verbinder für Abstandhalter-Hohlprofile für Mehrscheibenisoliergläser bezeichnet. Dieser Verbinder 1 besteht im wesentlichen aus einem Boden 2 und zwei an den Rändern des Bodens 2 angeformten Längsseitenstegen 3 und 4, so daß das U-förmige Profil des Verbinders 1 definiert wird.With 1 is in Fig. 1 a U-shaped connector for spacer hollow sections for Mehrscheibenisoliergläser designated. This connector 1 consists essentially of a bottom 2 and two integrally formed on the edges of the bottom 2 longitudinal side webs 3 and 4, so that the U-shaped profile of the connector 1 is defined.

An den Außenseiten der Längsseitenstege 3 und 4 sind nach außen weisende, T-förmige Lamellen 5 vorgesehen, die sich in den Hohlprofilen zu verkeilen vermögen.On the outer sides of the longitudinal side webs 3 and 4 outwardly facing, T-shaped blades 5 are provided, which are able to wedge in the hollow sections.

Im Bereich der Mitte des Verbinders 1 ist ebenfalls an den Außenseiten der Längsseitenstege 3 und 4 für jede Einsteckrichtung jeweils ein Mittenanschlag 6 vorgesehen, der die Einstecktiefe des Verbinders 1 in die Hohlprofile begrenzt.In the region of the middle of the connector 1, a center stop 6 is likewise provided on the outer sides of the longitudinal side webs 3 and 4 for each insertion direction, which delimits the insertion depth of the connector 1 into the hollow profiles.

Den Mittenanschlägen 6 ist jeweils ein Ausgleichselement 7 zugeordnet, das gegenüber den Mittenanschlägen 6 jeweils am anderen Längsseitensteg 3 und 4 vorgesehen ist.The center stops 6 are each assigned a compensation element 7, which is provided opposite the center stops 6 on the other longitudinal side web 3 and 4, respectively.

Das Ausgleichselement 7 ist elastisch federn ausgebildet und sorgt einerseits dafür, daß die Hohlprofile gegen die Mittenanschläge 6 stoßen. Andererseits werden etwaige Fertigungstoleranzen des Hohlprofils ausgeglichen. Ein Wackeln des Verbinders 1 im Hohlprofil wird vermieden.The compensating element 7 is resiliently formed and on the one hand ensures that the hollow sections abut against the middle stops 6. On the other hand, any manufacturing tolerances of the hollow profile are compensated. A wobble of the connector 1 in the hollow profile is avoided.

Der Boden 2 weist in jeder Einsteckrichtung eine Durchbrechung 8 auf.The bottom 2 has an opening 8 in each insertion direction.

Die T-förmigen Lamellen 5 sind aus einem an den Längsseitenstegen 3 bzw. 4 angelenkten Längssteg 51 und einem darauf ruhenden Quersteg 52 aufgebaut, der wenigstens annähernd parallel zu den Längsseitenstegen 3 bzw. 4 verläuft.The T-shaped lamellae 5 are constructed from a longitudinal web 51 articulated on the longitudinal side webs 3 and 4 and a transverse web 52 resting thereon which runs at least approximately parallel to the longitudinal web webs 3 and 4, respectively.

Der Längssteg 51 steht in einem Winkel von 90° von den Längsseitenstegen 3 bzw. 4 ab. Es ist aber auch denkbar, daß der Längssteg 51 entgegen der Einsteckrichtung des Steckverbinders in das Hohlprofil nach hinten geneigt ist.The longitudinal web 51 is at an angle of 90 ° from the longitudinal side webs 3 and 4, respectively. But it is also conceivable that the longitudinal web 51 is inclined against the insertion of the connector in the hollow profile to the rear.

Der Quersteg 52 ist entgegen der Einsteckrichtung des Steckverbinders 1 geneigt und auf dem von den Längsseitenstegen 3 bzw. 4 abgewandten Ende des Längssteges 51 in einem Winkel von etwa 85° gelagert. Andere Neigungswinkel sind denkbar. Es ist sogar denkbar, daß der Quersteg 52 unter 90° auf dem Längssteg 51 angeordnet ist.The cross bar 52 is inclined against the insertion direction of the connector 1 and mounted on the longitudinal side webs 3 and 4 facing away from the end of the longitudinal web 51 at an angle of about 85 °. Other angles of inclination are conceivable. It is even conceivable that the transverse web 52 is arranged at 90 ° on the longitudinal web 51.

Der Quersteg 52 weist wenigstens annähernd dieselbe Höhe wie das nicht dargestellte Hohlprofil auf. Der Quersteg 52 kann sich auf der gesamten Höhe vollflächig abstützen und sorgt dadurch einerseits für ein Verhaken an geringsten Unebenheiten der Innenseite des Hohlprofils und andererseits für eine erhebliche Haftreibungskraft. Beides zusammengenommen sorgt dafür, daß der Steckverbinder nur schwer wieder aus dem Hohlprofil herausgezogen werden kann. Eine sichere Befestigung ist damit gewährleistet.The crossbar 52 has at least approximately the same height as the hollow profile, not shown. The crossbar 52 can be supported over its entire surface over the entire height and thereby ensures on the one hand for snagging on the slightest bumps on the inside of the hollow profile and on the other hand for a considerable static friction force. Both together ensure that the connector is difficult to pull out of the hollow profile again. A secure attachment is guaranteed.

Um eine optimale Anlage des Quersteges 52 zu gewährleisten ist die T-förmige Lamelle 5 wenigstens teilweise flexibel ausgebildet.In order to ensure optimal contact of the crossbar 52, the T-shaped lamella 5 is at least partially flexible.

Der Längssteg 51 kann eine kleinere, dieselbe oder eine größere Höhe als der Quersteg 52 aufweisen. Bei einer kleineren Höhe des Längssteges 51 kann eine größere Flexibilität der Lamelle 5 geschaffen werden. Bei einer größeren Höhe kann eine zusätzliche Anpassung an das Hohlprofil erfolgen, wenn dieses zum Beispiel dachförmig ausgebildet ist. Ein etwaiger Zwischenraum wird ausgefüllt.The longitudinal web 51 may have a smaller, the same or a greater height than the transverse web 52. At a smaller height of the longitudinal web 51, a greater flexibility of the blade 5 can be created. At a greater height, an additional adaptation to the hollow profile can take place, if this is roof-shaped, for example. Any space is filled.

Der Quersteg 52 ist etwas entgegen der Einsteckrichtung geneigt angeordnet, damit ein leichtes Einschieben ermöglicht wird. Wird dann versucht den Steckverbinder herauszuziehen, legt sich der Quersteg 52 nicht nur vollflächig an die Innenseite des Hohlprofiles an, sondern die Querstege verkeilen sich regelrecht zwischen den beiden gegenüberliegenden Seitenwänden des Hohlprofiles.The crossbar 52 is disposed slightly inclined opposite to the insertion direction, so that an easy insertion is possible. If an attempt is then made to pull out the plug connector, the transverse web 52 not only abuts the entire surface of the inside of the hollow profile, but the transverse webs literally become wedged between the two opposite side walls of the hollow profile.

Durch diese Gestaltung der Lamellen 5 wird auch ein Toleranzausgleich geschaffen, mit dessen Hilfe der Verbinder 1 sich an unterschiedliche Hohlprofilbreiten anzupassen vermag.By this design of the slats 5, a tolerance compensation is created with the help of the connector 1 is able to adapt to different hollow profile widths.

Im mittleren Bereich der Seitenstege 3 und 4 ist eine Höhenverringerung 9 vorgesehen. Wird der Verbinder 1 in ein Hohlprofil eingeschoben, das eine etwas zu geringe Höhe aufweist. In diesem Fall findet eine Selbstanpassung des Steckverbinders 1 statt. An den oberen Enden der Seitenstege 3 und 4 bildet sich ein Span des Verbindermaterials. Dieser wird von der Vorderkante des Hohlprofils weggeschoben. Im Bereich der Höhenveringerrung 9 wird dieser Span eben durch die Höhenverringerung nach innen in den Zwischenraum zwischen den beiden Seitenstegen 3 und 4 hineingeleitet. Es wird damit verhindert, daß sich der Span zwischen die beiden Enden des Hohlprofiles klemmt und ein vollständiges Zusammenschieben verhindert.In the middle region of the side bars 3 and 4, a reduction in height 9 is provided. If the connector 1 is inserted into a hollow profile, which has a slightly too low height. In this case, a self-adaptation of the connector 1 takes place. At the upper ends of the side bars 3 and 4, a chip of the connector material is formed. This is pushed away from the front edge of the hollow profile. In the area of the Höhenveringerrung 9 this chip is just led in by the reduction in height inward in the space between the two side bars 3 and 4. It is thus prevented that the chip clamps between the two ends of the hollow profile and prevents complete pushing together.

Auf der Unterseite des Bodens können entlang und im Bereich der Seitenstege Widerhaken 10 vorgesehen sein, die als Auflaufschrägen ausgebildet und in unterschiedlichen Abständen zueinander angeordnet sein können.On the bottom of the bottom barbs 10 may be provided along and in the region of the side webs, which may be formed as chamfers and arranged at different distances from each other.
