Definitions
- the invention relates to a connector for spacer profiles for insulating glass panes with a base body which has a plug-in section on opposite sides, wherein the plug-in section is adapted to the spacer hollow profile, so that it can be inserted into the spacer hollow profile in one direction (plug-in direction), and a fuse unit, which is designed to secure an inserted spacer hollow profile against pulling out.
- the invention further relates to a method for producing such a connector.
- Connectors of the aforementioned type are well known and serve to connect so-called spacer hollow profiles together.
- Spacer hollow sections are required for insulating glass panes to keep the two or more glass panes at a distance and also to seal the interior space between two panes of glass to the outside.
- spacer hollow sections also referred to as spacers below, are connected to one another via plug connectors, such that the spacers are respectively inserted onto a longitudinal section, plug-in section, of the plug connector.
- plug connectors such that the spacers are respectively inserted onto a longitudinal section, plug-in section, of the plug connector.
- securing units are provided in the plug-in sections, which usually allow the insertion, the withdrawal of a spacer - if at all - allow only with great force.
- a connector which has as a securing unit outwardly projecting, elastically deformable fins on each insertion section. These slats are designed inclined or bent, wherein the inclination or bending can be formed in the insertion direction to the rear.
- plastic corner joints which are equipped with a straight wire.
- This solution has the disadvantage that they have a higher ratio of insertion to pull-out forces and do not have the ability to specifically adapt the forces of the profile and also require a much smaller tolerance field of the spacers.
- the insertion force changes with the wall thickness of the spacer profile used. The risk of breakage is increased by the damage of the side walls of the profile by strong restoring force of the inserted wire.
- the object of the present invention is to provide a connector, the o.g. Overcomes disadvantages.
- the securing unit comprises a plurality of elongate metal elements, each with two opposite Lijnsendabrisken provided within the Einsteckabrough and extending through the body, such that the two longitudinal end portions of a metal element on opposite sides of the body protrude to cooperate with the spacer hollow profile, and extend the two longitudinal end portions of the at least one metal element obliquely to the insertion and in the insertion direction.
- the shape in particular also allows the insertion and extraction forces easily and specifically adapted to the respective spacer hollow profile.
- the holding force of the connectors in the profiles can be easily adjusted by appropriate choice of the number of metal elements used.
- the pre-bent metal elements deform the profile less, because they work like a spring when plugged. Characterized in that the metal elements are formed longer (as, for example, a straight metal element), a skipping of the metal element is prevented by 180 °. Also, there is no longer the risk that the metal element pierces a profile wall. Consequently, the solution according to the invention offers a possibility to optimally adjust the insertion force, for example by the appropriate choice of the number of metal elements, without the risk of damage to the profile due to excessive restoring forces of the metal elements.
- the plurality of metal elements per plug-in section are provided, and the individual metal elements within a Einsteckabitess are spaced apart in the insertion direction.
- This measure has the advantage that the insertion and extraction forces are even better adapted to the respective spacer hollow profile, in particular by varying the number of metal elements used.
- the at least one metal element is designed as a wire, in particular with a colored cross section.
- the longitudinal end portions of a metal element extend at an angle of at least 30 ° relative to the insertion direction. This angular range has the advantage that the insertion forces are low, but the extraction forces are at a sufficiently high level, so that a high level of security against loosening of the spacer is ensured by the connector.
- At least one groove is provided in the insertion section of the base body into which a metal element can be inserted.
- This measure has the advantage that preconfigured metal elements, which have already been brought into their bent or kinked form, can be inserted.
- the production of such a connector is very easy.
- the metal element as a straight element into the base body and to bend the metal element into the desired shape in a subsequent step.
- the base body is preferably provided with corresponding recesses on the edge regions and a connection of the two recesses, so that the metal element can be inserted through the connection and can then be bent within the recesses.
- the connector is preferably designed as a corner connector, angle connector, linear or straight connector or cross connector. More preferably, the base body is made of plastic.
- the object underlying the invention is also achieved by a method for producing a connector according to the invention, wherein - as mentioned above - the at least one metal element is either preformed introduced into the body or initially introduced into the body and then bent into the desired shape.
- a connector is shown in perspective view and generally designated by the reference numeral 10.
- the connector 10 is designed as a corner connector 11, which serves to connect two spacer hollow profiles at an angle of 90 ° with each other.
- the connector 10 comprises a base body 12, which has a first insertion portion 14a and a second insertion portion 14b, wherein the two insertion portions 14a, 14b are connected to one another via a connecting element 16.
- the connecting element 16 is designed in the present embodiment as a corner element 17, which connects the two insertion portions 14 a, b at right angles to each other.
- a plug-in section 14 is rectangular in cross-section and extends from the connecting element 16 over a length L in a direction which runs counter to the insertion direction E.
- the two outer ends of the male portions are beveled to facilitate insertion of a spacer.
- Fig. 1 It can be seen that the connecting element 16 is formed larger in cross-section, so that stop surfaces 20 form, on which strike the spacers when reaching the end position.
- the stop surfaces 20 - seen in the circumferential direction - provided only in sections, so that the end of a spacer is not completely applied to the connecting element, but leaving a gap that can be filled with butyl for caulking.

In Fig. 2 this angle is denoted by ⁇ .
- the longitudinal end portions 42 of a metal element thus extend obliquely in the insertion direction towards the connecting element 16.
- the shape of the metal element 40 and / or the front wall 38 are selected so that a gap 44 remains between the wall 38 and the metal element 40. This is to ensure that the longitudinal end portion 42 of the metal element 40 is bendable in the insertion direction E, at least until it abuts against the wall 38.
- This flexibility enables the longitudinal end portions 42 of a metal element in the insertion direction E to be pressed when a spacer is inserted, so that the extent of the metal element is reduced at right angles to the longitudinal axis.
- a plurality of identically shaped recesses 30 are provided in each insertion section, each receiving a metal element 40.
- the metal elements are preferably provided evenly spaced in the longitudinal direction A. On the number of metal elements provided, the desired insertion and extraction forces can be adjusted and adapted to the spacer hollow profile.

Description
Die Erfindung betrifft einen Steckverbinder für Abstandhalterprofile für Isolierglasscheiben mit einem Grundkörper, der an gegenüberliegenden Seiten jeweils einen Einsteckabschnitt aufweist, wobei der Einsteckabschnitt an das Abstandhalterhohlprofil angepasst ist, so dass dieser in das Abstandhalterhohlprofil in einer Richtung (Einsteckrichtung) einsteckbar ist, und einer Sicherungseinheit, die ausgelegt ist, ein eingestecktes Abstandhalterhohlprofil gegen ein Herausziehen zu sichern. Die Erfindung betrifft ferner ein Verfahren zur Herstellung eines solchen Steckverbinders.The invention relates to a connector for spacer profiles for insulating glass panes with a base body which has a plug-in section on opposite sides, wherein the plug-in section is adapted to the spacer hollow profile, so that it can be inserted into the spacer hollow profile in one direction (plug-in direction), and a fuse unit, which is designed to secure an inserted spacer hollow profile against pulling out. The invention further relates to a method for producing such a connector.
Steckverbinder der vorgenannten Art sind allgemein bekannt und dienen dazu, sogenannte Abstandhalterhohlprofile miteinander zu verbinden. Abstandhalterhohlprofile werden bei Isolierglasscheiben benötigt, um die zwei oder mehreren Glasscheiben auf Abstand zu halten und zudem den Innenraum zwischen zwei Glasscheiben nach außen hin abzudichten.Connectors of the aforementioned type are well known and serve to connect so-called spacer hollow profiles together. Spacer hollow sections are required for insulating glass panes to keep the two or more glass panes at a distance and also to seal the interior space between two panes of glass to the outside.
Solche Abstandhalterhohlprofile, nachfolgend auch Abstandhalter genannt, werden über Steckverbinder miteinander verbunden, derart, dass die Abstandhalter jeweils auf einen Längsabschnitt, Einsteckabschnitt, des Steckverbinders gesteckt werden. Um zu verhindern, dass sich die Abstandhalter wieder lösen, sind in den Einsteckabschnitten Sicherungseinheiten vorgesehen, die üblicherweise das Einstecken ermöglichen, das Herausziehen eines Abstandhalters - wenn überhaupt - nur mit großer Kraftaufwendung zulassen.Such spacer hollow sections, also referred to as spacers below, are connected to one another via plug connectors, such that the spacers are respectively inserted onto a longitudinal section, plug-in section, of the plug connector. In order to prevent the spacers from loosening again, securing units are provided in the plug-in sections, which usually allow the insertion, the withdrawal of a spacer - if at all - allow only with great force.
Bekannt sind verschiedene Steckverbinder aus Metall oder Kunststoff, die jedoch alle den Nachteil aufweisen, entweder nur einen begrenzten Toleranzausgleich für Toleranzen im Abstandhalterprofil bereitzustellen oder prinzipbedingt eher annähernd die gleichen Einsteck- und Auszugskräfte besitzen.Various connectors are known metal or plastic, however, all of which have the disadvantage of either only provide a limited tolerance compensation for tolerances in the spacer profile or principle inherently have approximately the same insertion and extraction forces.
Aus der Druckschrift
Ein Nachteil dieses Steckverbinders kann darin gesehen werden, dass die Einsteck- und Auszugskräfte annähernd gleich sind.A disadvantage of this connector can be seen in the fact that the insertion and extraction forces are approximately equal.
Ferner sind Eckverbinder aus Kunststoff bekannt, die mit einem geraden Draht ausgestattet sind. Diese Lösung hat den Nachteil, dass sie ein höheres Verhältnis von Einsteck- zu Auszugskräften aufweisen sowie nicht die Möglichkeit besitzen, speziell die Kräfte dem Profil anzupassen und zudem ein deutlich kleineres Toleranzfeld der Abstandhalter benötigen. Darüber hinaus besteht ein Nachteil darin, dass sich die Einschubkraft mit der Wandstärke des verwendeten Abstandhalter-Profils verändert. Auch die Bruchgefahr wird erhöht durch die Beschädigung der Seitenwände des Profils durch starke Rückstellkraft des eingesetzten Drahts.Furthermore, plastic corner joints are known, which are equipped with a straight wire. This solution has the disadvantage that they have a higher ratio of insertion to pull-out forces and do not have the ability to specifically adapt the forces of the profile and also require a much smaller tolerance field of the spacers. In addition, there is a disadvantage in that the insertion force changes with the wall thickness of the spacer profile used. The risk of breakage is increased by the damage of the side walls of the profile by strong restoring force of the inserted wire.
Die Aufgabe der vorliegenden Erfindung besteht vor diesem Hintergrund darin, einen Steckverbinder zu schaffen, der die o.g. Nachteile überwindet.The object of the present invention is to provide a connector, the o.g. Overcomes disadvantages.
Die Aufgabe wird bei dem eingangs genannten Steckverbinder dadurch gelöst, dass die Sicherungseinheit mehrere längliche Metallelemente mit jeweils zwei gegenüberliegenden Längsendabschnitten umfasst, die innerhalb des Einsteckabschnitt vorgesehen sind und sich durch den Grundkörper erstrecken, derart, dass die beiden Längsendabschnitte eines Metallelements an gegenüberliegenden Seiten des Grundkörpers hervorstehen, um mit dem Abstandhalterhohlprofil zusammenwirken zu können, und sich die beiden Längsendabschnitte des zumindest einen Metallelements schräg zur Einsteckrichtung und in Einsteckrichtung erstrecken.The object is achieved with the connector mentioned above in that the securing unit comprises a plurality of elongate metal elements, each with two opposite Längsendabschnitten provided within the Einsteckabschnitt and extending through the body, such that the two longitudinal end portions of a metal element on opposite sides of the body protrude to cooperate with the spacer hollow profile, and extend the two longitudinal end portions of the at least one metal element obliquely to the insertion and in the insertion direction.
Durch die spezielle Form des Metallelements können geringe Einsteck- und hohe Auszugskräfte realisiert werden, wobei die Formgebung insbesondere auch ermöglicht, die Einsteck- und Auszugskräfte einfach und speziell dem jeweiligen Abstandhalterhohlprofil anzupassen. Die Haltekraft der Steckverbinder in den Profilen kann durch entsprechende Wahl der Anzahl der verwendeten Metallelemente einfach eingestellt werden. Die vorgebogenen Metallelemente verformen das Profil weniger, da sie beim Einstecken wie eine Feder arbeiten. Dadurch, dass die Metallelemente länger ausgebildet sind (als bspw. ein gerades Metallelement) wird ein Überspringen des Metallelements um 180° verhindert. Auch besteht nicht mehr die Gefahr, dass das Metallelement eine Profilwand durchbohrt. Die erfindungsgemäße Lösung bietet folglich eine Möglichkeit, die Einschubkraft optimal einzustellen, bspw. durch die entsprechende Wahl der Anzahl von Metallelementen, ohne die Gefahr von Beschädigungen am Profil durch zu große Rückstellkräfte der Metallelemente.Due to the special shape of the metal element low insertion and high pull-out forces can be realized, the shape in particular also allows the insertion and extraction forces easily and specifically adapted to the respective spacer hollow profile. The holding force of the connectors in the profiles can be easily adjusted by appropriate choice of the number of metal elements used. The pre-bent metal elements deform the profile less, because they work like a spring when plugged. Characterized in that the metal elements are formed longer (as, for example, a straight metal element), a skipping of the metal element is prevented by 180 °. Also, there is no longer the risk that the metal element pierces a profile wall. Consequently, the solution according to the invention offers a possibility to optimally adjust the insertion force, for example by the appropriate choice of the number of metal elements, without the risk of damage to the profile due to excessive restoring forces of the metal elements.
Bei einer bevorzugten Weiterbildung sind die mehreren Metallelemente pro Einsteckabschnitt vorgesehen, und die einzelnen Metallelemente innerhalb eines Einsteckabschnitts sind in Einsteckrichtung beabstandet angeordnet.In a preferred embodiment, the plurality of metal elements per plug-in section are provided, and the individual metal elements within a Einsteckabschnitts are spaced apart in the insertion direction.
Diese Maßnahme hat den Vorteil, dass die Einsteck- und Auszugskräfte noch besser an das jeweilige Abstandhalterhohlprofil anpassbar, indem insbesondere die Anzahl der eingesetzten Metallelemente variiert wird.This measure has the advantage that the insertion and extraction forces are even better adapted to the respective spacer hollow profile, in particular by varying the number of metal elements used.
Bei einer bevorzugten Weiterbildung ist das zumindest eine Metallelement als Draht, insbesondere mit buntem Querschnitt ausgebildet.In a preferred development, the at least one metal element is designed as a wire, in particular with a colored cross section.
Diese Form hat sich in der Praxis als besonders vorteilhaft herausgestellt. Allerdings können auch andere Querschnitte neben einem runden Querschnitt eingesetzt werden. Beispielsweise können als Metallelemente auch Flachbandelemente mit einem rechteckigen Querschnitt verwendet werden.This form has been found in practice to be particularly advantageous. However, other cross sections besides a round cross section can be used. For example, ribbon elements with a rectangular cross-section can also be used as metal elements.
Bei einer bevorzugten Weiterbildung verlaufen die Längsendabschnitte eines Metallelements in einem Winkel von zumindest 30° bezogen auf die Einsteckrichtung. Dieser Winkelbereich hat den Vorteil, dass die Einsteckkräfte gering sind, die Auszugskräfte jedoch auf einem ausreichend hohen Niveau liegen, so dass eine hohe Sicherheit gegen ein Lösen des Abstandhalters vom Steckverbinder gewährleistet ist.In a preferred embodiment, the longitudinal end portions of a metal element extend at an angle of at least 30 ° relative to the insertion direction. This angular range has the advantage that the insertion forces are low, but the extraction forces are at a sufficiently high level, so that a high level of security against loosening of the spacer is ensured by the connector.
Bei einer bevorzugten Weiterbildung ist im Einsteckabschnitt des Grundkörpers zumindest eine Nut vorgesehen, in die ein Metallelement einlegbar ist.In a preferred development, at least one groove is provided in the insertion section of the base body into which a metal element can be inserted.
Diese Maßnahme hat den Vorteil, dass vorkonfigurierte Metallelemente, die bereits in ihre gebogene bzw. geknickte Form gebracht sind, eingelegt werden können. Die Fertigung eines solchen Steckverbinders ist dadurch sehr einfach.This measure has the advantage that preconfigured metal elements, which have already been brought into their bent or kinked form, can be inserted. The production of such a connector is very easy.
Alternativ ist es jedoch auch denkbar, das Metallelement als gerades Element in den Grundkörper einzuschießen und in einem nachfolgenden Schritt das Metallelement in die gewünschte Form zu biegen. Der Grundkörper ist hierfür bevorzugt mit entsprechenden Ausnehmungen an den Randbereichen und einer Verbindung der beiden Ausnehmungen versehen, so dass das Metallelement durch die Verbindung hindurchgesteckt werden kann und innerhalb der Ausnehmungen dann gebogen werden kann.Alternatively, however, it is also conceivable to insert the metal element as a straight element into the base body and to bend the metal element into the desired shape in a subsequent step. For this purpose, the base body is preferably provided with corresponding recesses on the edge regions and a connection of the two recesses, so that the metal element can be inserted through the connection and can then be bent within the recesses.
Der Steckverbinder ist bevorzugt als Eckverbinder, Winkelverbinder, Linear- bzw. Geradeverbinder oder Kreuzverbinder ausgebildet. Weiter bevorzugt ist der Grundkörper aus Kunststoff hergestellt.The connector is preferably designed as a corner connector, angle connector, linear or straight connector or cross connector. More preferably, the base body is made of plastic.
Die der Erfindung zugrundeliegende Aufgabe wird auch von einem Verfahren zur Herstellung eines erfindungsgemäßen Steckverbinders gelöst, wobei - wie zuvor erwähnt - das zumindest eine Metallelement entweder bereits vorgeformt in den Grundkörper eingebracht wird oder zunächst in den Grundkörper eingebracht und anschließend in die gewünschte Form gebogen wird.The object underlying the invention is also achieved by a method for producing a connector according to the invention, wherein - as mentioned above - the at least one metal element is either preformed introduced into the body or initially introduced into the body and then bent into the desired shape.
Es versteht sich, dass die vorstehend genannten und die nachstehend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen.It is understood that the features mentioned above and those yet to be explained below can be used not only in the particular combination given, but also in other combinations or in isolation, without departing from the scope of the present invention.

Da der grundsätzliche Aufbau und die Funktion eines Steckverbinders 10 bekannt sind, soll darauf nicht weiter eingegangen werden. Es wird vielmehr beispielsweise auf die Druckschrift
Der Steckverbinder 10 umfasst einen Grundkörper 12, der einen ersten Einsteckabschnitt 14a und einen zweiten Einsteckabschnitt 14b aufweist, wobei die beiden Einsteckabschnitte 14a, 14b über ein Verbindungselement 16 miteinander verbunden sind. Das Verbindungselement 16 ist im vorliegenden Ausführungsbeispiel als Eckelement 17 ausgelegt, das die beiden Einsteckabschnitte 14a, b rechtwinklig miteinander verbindet.The
Die beiden Einsteckabschnitte sind identisch ausgebildet. Ein Einsteckabschnitt 14 ist im Querschnitt rechteckig ausgebildet und erstreckt sich ausgehend von dem Verbindungselement 16 über eine Länge L in eine Richtung, die entgegen der Einsteckrichtung E verläuft. Die beiden äußeren Enden der Einsteckabschnitte sind gefast ausgebildet, um ein Einstecken eines Abstandhalters zu erleichtern.The two insertion sections are identical. A plug-in

Die Ausnehmung 30 wird in Einsteckrichtung E nach vorne von einer Wand 38 begrenzt, die schräg zur Längsachse A verläuft. Insbesondere verläuft die Wand 38 nach innen hin zur gegenüberliegenden Wand 36. Damit nimmt die Länge der Ausnehmung 30 zur Mitte hin ab, wie dies deutlich in

Dies führt dazu, dass sich die Längsendabschnitte im Abstandhalter "verkrallen" und damit ein Herausziehen - wenn überhaupt - nur mit sehr großer Kraft zulassen.Thus, the attachment of a spacer on the male portion with little force is possible.

Um solche vorgeformten Metallelemente in die Ausnehmungen zu legen, sind in einer weiteren Ausführungsform eines Steckverbinders 10 Nuten 70 im Einsteckabschnitt 14 vorgesehen, die die innerhalb des Einsteckabschnitts 14 liegenden Ausnehmungen 30 nach außen verbinden. Die Nuten 70 haben dabei in etwa die Form der Metallelemente 40.In order to place such preformed metal elements in the
Die Metallelemente 40 können folglich von außen durch die Nuten 70 in die darunterliegende Ausnehmung 30 gebracht werden. Unterscheidet sich die Form der Nut 70 etwas von der Form eines Metallelements 40, kann leicht verhindert werden, dass die Metallelemente 40 nach dem Einbringen in die Ausnehmung 30 wieder herausfallen.The
Da sich der Steckverbinder 10 als Kunststoffteil herstellen lässt, und die Metallelemente sehr einfach einbringbar sind, ergibt sich insgesamt ein sehr kostengünstiger Steckverbinder, der geringe Einsteckkräfte und hohe Auszugskräfte bereitstellt. Damit ist das Einstecken in ein Abstandhalterhohlprofil mit geringer Kraft möglich, wobei die eingesteckte Position mit sehr hoher Sicherheit beibehalten wird. Ein Lösen des Steckverbinders vom Abstandhalterhohlprofil ist nahezu unmöglich, insbesondere im bestimmungsgemäßen Gebrauch.Since the
