Definitions

  • the invention relates to a piece of furniture with a cable bushing, which is provided in a furniture wall, in particular in a skirting board wall, according to claim 1, and to a method for forming such a cable bushing according to claim 12.
  • Furniture such as sideboards, cupboards or the like often have skirting boards or plinths on which the furniture body is placed or which, if the piece of furniture rests on separate feet, serve to cover the space between the furniture body and the floor.
  • electricity is required inside the piece of furniture if sockets are to be provided there or if an electrically height-adjustable table leg projects into the piece of furniture, the drive of which must be supplied with current.
  • the invention is therefore based on the object of creating a piece of furniture with a cable bushing that can be easily manufactured and has an effective, easy-to-install strain relief for cables. Furthermore, a method for the simple formation of a cable bushing with a cable strain relief in a skirting board of furniture is to be created.
  • a cable bushing is created, which can be produced in a quick and simple manner if required, and a simple, fast fastening a cable strain relief device on a wall, in particular on the skirting board wall of a piece of furniture.
  • the skirting board can be designed in such a way that a bending tab or a pair of bending tabs arranged next to one another is provided at preferably several locations on the skirting board, which is formed by a partially cut section of the skirting board wall. As long as these bending tabs have not yet been bent into the angled position, they run in the main plane of the furniture wall and cover the wall openings to be made as required. The wall openings remain closed at the points where the bending tabs are not bent.
  • the bending tabs are partially cut free and are only connected to the furniture wall by bridge sections at the points intended for bending, bending of the bending tabs into the angled open position is possible in a simple manner.
  • the angled bending brackets serve to support the insertion frame, as a result of which it is held securely in the skirting board and can be inserted into the wall opening in a simple manner, in particular without tools.
  • the bending tabs therefore have a dual function, namely to cover the wall opening in the unopened state on the one hand and to support the insertion frame, preferably in the region of both side walls of the insertion frame, on the other hand.
  • the fact that the cable strain relief device can be positively engaged with the plug-in frame means that the cable strain relief device can be fixed within the plug-in frame quickly and easily without tools.
  • the wall opening is laterally delimited by two bending flaps, which are formed from two wall sections of the furniture wall arranged next to one another, which are designed like door wings and can be bent into an open position from a closed starting position, in which they lie in a main plane of the furniture wall.
  • the bending axis, about which each bending tab can be pivoted, is arranged vertically in the lateral edge area of the respective bending tab.
  • a wall opening it is also possible for a wall opening to be covered only by a single bendable bending tab.
  • the push-in frame is only supported on one side by the bent flap.
  • two bending tabs lying next to one another are provided for a wall opening, these are preferably connected to one another in their starting position by means of at least one separable connecting section.
  • This connecting section stabilizes the two bending tabs in the unopened state, ie when they are in the plane of the furniture wall. This prevents accidental bending of the bending tabs. If a cable duct is to be created at the point in question, the connecting section is severed so that the bending tabs can be bent inwards. It is easily possible for the connecting section to have a smaller wall thickness than the furniture wall, so that the two bending tabs can be separated in a particularly simple manner.
  • the bending tabs are preferably each connected to the adjacent furniture wall only via at least one easily bendable bridge section, which is located in a laterally outer edge region of the bending tabs.
  • two such bridge sections are provided per bending bracket, such a bridge section being arranged in the lower end region of the bending bracket and the second bridge section near the upper end region of the respective bending bracket, while the bending bracket between these two bridge sections is separated by corresponding longitudinal slots.
  • the insertion frame preferably has laterally projecting webs which are designed to reach over and under the bending tabs which are in the open position. These webs are expediently formed by lateral extensions of the top and bottom walls of the plug-in frame, which protrude laterally beyond the side walls of the plug-in frame.
  • the bending tabs advantageously have an upper edge which is spaced apart in the vertical direction from the adjacent furniture wall, so that an intermediate space is formed, into which laterally projecting webs of the plug-in frame can extend.
  • the plug-in frame has an outer stop which bears against the outside of the furniture wall when the plug-in frame is inserted, and at least one retaining projection which engages behind the furniture wall in the inserted state of the plug-in frame in such a way that it is prevented from moving against the direction of insertion.
  • the one on the outside of the Furniture wall that can be brought into contact with the outer stop expediently consists of the front end wall of the plug-in frame, which projects laterally and upwards beyond the side walls or top wall of the plug-in frame so that the edge areas of the furniture wall surrounding the wall opening are overlapped.
  • the retaining projection provided on the plug-in frame expediently consists of a locking lug projecting upward above the ceiling wall of the plug-in frame, with a bevel so that the plug-in frame can be locked in a clip-like manner on the furniture wall.
  • the plug-in frame has a gap on the bottom or a defined bridge element with a predetermined separation point to form a gap through which a cable can be inserted into the plug-in frame.
  • a gap is always advantageous when the height of the plug-in frame is not sufficient to be able to pass a cable plug in the longitudinal direction of the cable lead-through space.
  • the bridge area stabilizes the base wall of the plug-in frame when intact and, on the other hand, enables the gap to be easily produced if this should be necessary.
  • the webs and grooves are arranged such that the cable strain relief device inserted at a certain point in the plug-in frame and then moved by a further movement in the plug-in frame in such a way that it can no longer be pulled out of the plug-in frame in the longitudinal direction of the cable and thus no longer be pulled out of the baseboard.
  • the webs of the plug-in frame advantageously consist of vertical webs arranged on the inside of the side walls of the plug-in frame and having an upper end which is spaced apart from the top wall of the insertion frame, so that an insertion gap is present between the web and the top wall.
  • the positive-locking connection device advantageously comprises lateral holding strips provided on the cable strain relief device, in which guide grooves are provided, which are designed for holding engagement with the webs. This makes it possible to insert the cable strain relief device in an elevated position into the insertion gap between the vertical web and the top wall of the plug-in frame until the grooves of the cable strain relief device are aligned with the vertical webs, and then to lower the cable strain relief device, as a result of which the webs engage in the grooves.
  • the cable strain relief device comprises an upper part and a lower part, between which at least one cable can be clamped, the upper part having side walls and a plate-shaped ceiling wall which protrudes laterally beyond the side walls and forms the retaining strips.

Furthermore, it is also readily possible for a plurality of sections 9 to be provided on one or more sides of the furniture 1. Furthermore, it is also possible that such sections 9 are not provided or not only in the skirting board wall 8, but in another wall of the furniture 1 if this wall consists of a material that can be deformed by bending. Such a wall, in particular the skirting board wall 8, is therefore more generally referred to below as a furniture wall 11.

Description

Die Erfindung betrifft ein Möbel mit Kabeldurchführung, die in einer Möbelwand, insbesondere in einer Sockelleistenwand, vorgesehen ist, gemäß Anspruch 1, sowie ein Verfahren zum Ausbilden einer derartigen Kabeldurchführung gemäß Anspruch 12.The invention relates to a piece of furniture with a cable bushing, which is provided in a furniture wall, in particular in a skirting board wall, according to claim 1, and to a method for forming such a cable bushing according to claim 12.

Möbel wie beispielsweise Sideboards, Schränke oder dergleichen weisen häufig Sockelleisten oder Sockelblenden auf, auf denen der Möbelkorpus aufgesetzt ist oder die, falls das Möbelstück auf separaten Füßen ruht, zum Abdecken des Zwischenraums zwischen Möbelkorpus und Boden dienen.Furniture such as sideboards, cupboards or the like often have skirting boards or plinths on which the furniture body is placed or which, if the piece of furniture rests on separate feet, serve to cover the space between the furniture body and the floor.

Bei derartigen Möbeln ist es häufig erforderlich, Kabel, beispielsweise Strom- oder Datenkabel in das Innere des Möbels hineinzuführen, um dort elektrische oder elektronische Geräte anschließen zu können.With such furniture, it is often necessary to lead cables, for example power or data cables, into the interior of the furniture in order to be able to connect electrical or electronic devices there.

Beispielsweise wird im Inneren des Möbelstücks Strom benötigt, wenn dort Steckdosen vorgesehen werden sollen oder wenn in das Möbelstück ein elektrisch höhenverstellbarer Tischfuß hineinragt, dessen Antrieb mit Strom versorgt werden muss.For example, electricity is required inside the piece of furniture if sockets are to be provided there or if an electrically height-adjustable table leg projects into the piece of furniture, the drive of which must be supplied with current.

Um durch Sockelleisten hindurch ein Kabel einzuführen, werden üblicherweise Kabeldurchführungen verwendet, die lediglich aus einer ausreichend dimensionierten Aussparung oder Öffnung in der Sockelleiste bestehen. Die Kabel werden dann lose durch diese Aussparung hindurch bis zur Anschlussstelle des Kabels innerhalb des Möbels geführt. Die erforderliche Zugentlastung für das Kabel ist dann im Bereich dieser Anschlussstelle vorgesehen. Wird auf das Kabel eine äußere Zugkraft aufgebracht, setzt sich diese bis zur Anschlussstelle innerhalb des Möbels fort. Weiterhin ist bei einer derartigen Kabeldurchführung nachteilig, dass keine definierte Kabellänge zwischen der Sockelleiste und der Anschlussstelle im Inneren des Möbels eingestellt und zuverlässig aufrechterhalten werden kann. Aus dem Stand der Technik sind Möbel mit Kabeldurchführungen zum Beispiel aus den Patentschriften DE 85 17 395 U1 , US 6133 528 und JP 11-56482 bekannt.In order to insert a cable through skirting boards, cable bushings are usually used, which only consist of a sufficiently dimensioned recess or opening in the skirting board. The cables are then loosely routed through this recess to the connection point of the cable inside the furniture. The necessary strain relief for the cable is then provided in the area of this connection point. If an external tensile force is applied to the cable, it continues to the connection point within the furniture. Another disadvantage of such a cable lead-through is that no defined cable length can be set and reliably maintained between the skirting board and the connection point in the interior of the piece of furniture. Furniture with cable feedthroughs, for example from the patent specifications, are from the prior art DE 85 17 395 U1 , US 6133 528 and JP 11-56482 known.

Der Erfindung liegt daher die Aufgabe zu Grunde, ein Möbel mit einer Kabeldurchführung zu schaffen, die einfach hergestellt werden kann und eine wirkungsvolle, einfach zu montierende Zugentlastung für Kabel aufweist. Weiterhin soll ein Verfahren zum einfachen Ausbilden einer Kabeldurchführung mit einer Kabelzugentlastung in einer Sockelleiste von Möbeln geschaffen werden.The invention is therefore based on the object of creating a piece of furniture with a cable bushing that can be easily manufactured and has an effective, easy-to-install strain relief for cables. Furthermore, a method for the simple formation of a cable bushing with a cable strain relief in a skirting board of furniture is to be created.

Diese Aufgabe wird erfindungsgemäß durch ein Möbel mit einer Kabeldurchführung mit den Merkmalen des Anspruchs 1 und ein Verfahren zum Ausbilden einer Kabeldurchführung gemäß Merkmal 12 gelöst. Vorteilhafte Ausführungsformen der Erfindung sind in den weiteren Ansprüchen beschrieben.This object is achieved by a piece of furniture with a cable duct with the features of the claim 1 and a method for forming a cable bushing according to feature 12 is achieved. Advantageous embodiments of the invention are described in the further claims.

The method according to the invention for forming a cable bushing with a cable strain relief in a furniture wall, in particular in a skirting board wall of furniture, is characterized by the following steps:
  • Providing a piece of furniture with a furniture wall that has at least one bending tab that is partially separated from the adjacent furniture wall or that can be partially separated via defined predetermined separation points,
  • Bending the bending tab into an opening position angled to the adjacent furniture wall in order to form a wall opening in the furniture wall,
  • Inserting a plug-in frame into the wall opening, the plug-in frame being brought into holding engagement with an edge region of the furniture wall delimiting the wall opening and the at least one bending tab,
  • Clamping a cable on or in a cable strain relief device outside the plug-in frame,
  • Inserting the cable strain relief device into the plug-in frame,
  • Anchoring the cable strain relief device within the plug-in frame by moving or rotating the cable strain relief device in such a way that the cable strain relief device is brought into a form-fitting holding engagement with the plug-in frame.

Mit Hilfe der Erfindung wird eine Kabeldurchführung geschaffen, die bei Bedarf auf schnelle und einfache Weise hergestellt werden kann und ein einfaches, schnelles Befestigen einer Kabelzugentlastungseinrichtung an einer Wand, insbesondere an der Sockelleistenwand eines Möbelstücks ermöglicht. Die Sockelleiste kann dabei derart ausgebildet sein, dass an vorzugsweise mehreren Stellen der Sockelleiste eine Biegelasche oder ein nebeneinander angeordnetes Paar von Biegelaschen vorgesehen ist, die bzw. das durch einen teilweise frei geschnittenen Abschnitt der Sockelleistenwand gebildet wird. Solange diese Biegelaschen noch nicht in die abgewinkelte Stellung umgebogen sind, verlaufen sie in der Hauptebene der Möbelwand und decken die bei Bedarf herzustellenden Wandöffnungen bündig ab. An den Stellen, an denen die Biegelaschen nicht umgebogen werden, bleiben die Wandöffnungen somit verschlossen. Dadurch, dass die Biegelaschen jedoch teilweise freigeschnitten und nur an den zum Umbiegen bestimmten Stellen durch Brückenabschnitte mit der Möbelwand verbunden sind, ist das Umbiegen der Biegelaschen in die abgewinkelte Öffnungsstellung auf einfache Weise möglich. Die abgewinkelten Biegelaschen dienen zum Abstützen des Einsteckrahmens, wodurch dieser sicher in der Sockelleiste gehalten wird und auf einfache Weise, insbesondere werkzeuglos, in die Wandöffnung eingesteckt werden kann. Die Biegelaschen haben somit eine zweifache Funktion, nämlich einerseits die Wandöffnung im ungeöffneten Zustand abzudecken, und andererseits den Einsteckrahmen, vorzugweise im Bereich beider Seitenwände des Einsteckrahmens, zu stützen. Dadurch, dass die Kabelzugentlastungseinrichtung formschlüssig mit dem Einsteckrahmen in Halteeingriff gebracht werden kann, ist eine werkzeuglose, einfache und schnelle Festlegung der Kabelzugentlastungseinrichtung innerhalb des Einsteckrahmens möglich.With the help of the invention, a cable bushing is created, which can be produced in a quick and simple manner if required, and a simple, fast fastening a cable strain relief device on a wall, in particular on the skirting board wall of a piece of furniture. The skirting board can be designed in such a way that a bending tab or a pair of bending tabs arranged next to one another is provided at preferably several locations on the skirting board, which is formed by a partially cut section of the skirting board wall. As long as these bending tabs have not yet been bent into the angled position, they run in the main plane of the furniture wall and cover the wall openings to be made as required. The wall openings remain closed at the points where the bending tabs are not bent. However, because the bending tabs are partially cut free and are only connected to the furniture wall by bridge sections at the points intended for bending, bending of the bending tabs into the angled open position is possible in a simple manner. The angled bending brackets serve to support the insertion frame, as a result of which it is held securely in the skirting board and can be inserted into the wall opening in a simple manner, in particular without tools. The bending tabs therefore have a dual function, namely to cover the wall opening in the unopened state on the one hand and to support the insertion frame, preferably in the region of both side walls of the insertion frame, on the other hand. The fact that the cable strain relief device can be positively engaged with the plug-in frame means that the cable strain relief device can be fixed within the plug-in frame quickly and easily without tools.

Gemäß einer vorteilhaften Ausführungsform wird die Wandöffnung seitlich durch zwei Biegelaschen begrenzt, die aus zwei nebeneinander angeordneten Wandabschnitten der Möbelwand gebildet werden, die türflügelartig ausgebildet und von einer geschlossenen Ausgangsstellung, in der sie in einer Hauptebene der Möbelwand liegen, in eine Öffnungsstellung biegbar sind. Die Biegeachse, um welche jede Biegelasche schwenkbar ist, ist dabei vertikal im seitlichen Randbereich der jeweiligen Biegelasche angeordnet.According to an advantageous embodiment, the wall opening is laterally delimited by two bending flaps, which are formed from two wall sections of the furniture wall arranged next to one another, which are designed like door wings and can be bent into an open position from a closed starting position, in which they lie in a main plane of the furniture wall. The bending axis, about which each bending tab can be pivoted, is arranged vertically in the lateral edge area of the respective bending tab.

Alternativ hierzu ist es jedoch auch möglich, dass eine Wandöffnung nur durch eine einzige umbiegbare Biegelasche abgedeckt wird. In diesem Fall wird der Einsteckrahmen nur einseitig durch die umgebogene Biegelasche gestützt.As an alternative to this, however, it is also possible for a wall opening to be covered only by a single bendable bending tab. In this case, the push-in frame is only supported on one side by the bent flap.

Sind für eine Wandöffnung zwei nebeneinander liegende Biegelaschen vorgesehen, sind diese in ihrer Ausgangsstellung vorzugsweise mittels mindestens eines trennbaren Verbindungsabschnitts miteinander verbunden. Dieser Verbindungsabschnitt stabilisiert die beiden Biegelaschen im ungeöffneten Zustand, d.h. wenn sie sich in der Ebene der Möbelwand befinden. Ein versehentliches Verbiegen der Biegelaschen wird hierdurch verhindert. Soll an der betreffenden Stelle eine Kabeldurchführung geschaffen werden, wird der Verbindungsabschnitt durchtrennt, so dass die Biegelaschen nach innen umgebogen werden können. Es ist ohne weiteres möglich, dass der Verbindungsabschnitt eine geringere Wandstärke als die Möbelwand aufweist, so dass das Trennen der beiden Biegelaschen auf besonders einfache Weise möglich ist. Vorzugsweise sind die Biegelaschen mit der angrenzenden Möbelwand jeweils lediglich über mindestens einen leicht biegbaren Brückenabschnitt verbunden, der sich in einem seitlich äußeren Randbereich der Biegelaschen befindet. Vorzugsweise sind pro Biegelasche zwei derartige Brückenabschnitte vorgesehen, wobei sich ein derartiger Brückenabschnitt im unteren Endbereich der Biegelasche und der zweite Brückenabschnitt nahe dem oberen Endbereich der jeweiligen Biegelasche angeordnet ist, während die Biegelaschen zwischen diesen beiden Brückenabschnitten durch entsprechende Längsschlitze abgetrennt ist.If two bending tabs lying next to one another are provided for a wall opening, these are preferably connected to one another in their starting position by means of at least one separable connecting section. This connecting section stabilizes the two bending tabs in the unopened state, ie when they are in the plane of the furniture wall. This prevents accidental bending of the bending tabs. If a cable duct is to be created at the point in question, the connecting section is severed so that the bending tabs can be bent inwards. It is easily possible for the connecting section to have a smaller wall thickness than the furniture wall, so that the two bending tabs can be separated in a particularly simple manner. The bending tabs are preferably each connected to the adjacent furniture wall only via at least one easily bendable bridge section, which is located in a laterally outer edge region of the bending tabs. Preferably, two such bridge sections are provided per bending bracket, such a bridge section being arranged in the lower end region of the bending bracket and the second bridge section near the upper end region of the respective bending bracket, while the bending bracket between these two bridge sections is separated by corresponding longitudinal slots.

Vorzugsweise weist der Einsteckrahmen seitlich vorspringende Stege auf, die ausgebildet sind, die sich in der Öffnungsstellung befindenden Biegelaschen zu über- und untergreifen. Zweckmäßigerweise werden diese Stege durch seitliche Verlängerungen der Decken- und Bodenwand des Einsteckrahmens gebildet, welche seitlich über die Seitenwände des Einsteckrahmens vorstehen.The insertion frame preferably has laterally projecting webs which are designed to reach over and under the bending tabs which are in the open position. These webs are expediently formed by lateral extensions of the top and bottom walls of the plug-in frame, which protrude laterally beyond the side walls of the plug-in frame.

Vorteilhafterweise haben die Biegelaschen einen oberen Rand, der in vertikaler Richtung zur angrenzenden Möbelwand beabstandet ist, so dass ein Zwischenraum gebildet wird, in den sich seitlich vorspringende Stege des Einsteckrahmens hinein erstrecken können.The bending tabs advantageously have an upper edge which is spaced apart in the vertical direction from the adjacent furniture wall, so that an intermediate space is formed, into which laterally projecting webs of the plug-in frame can extend.

Vorteilhafterweise weist der Einsteckrahmen einen äußeren Anschlag, der im eingesteckten Zustand des Einsteckrahmens an der Außenseite der Möbelwand anliegt, und mindestens einen Rückhaltevorsprung auf, der im eingesteckten Zustand des Einsteckrahmens die Möbelwand derart hintergreift, dass ein Verschieben entgegen der Einsteckrichtung verhindert wird. Die an der Außenseite der Möbelwand zur Anlage bringbare äußere Anschlag besteht zweckmäßigerweise aus der vorderen Stirnwand des Einsteckrahmens, welcher seitlich und nach oben über die Seitenwände bzw. Deckenwand des Einsteckrahmens so weit vorsteht, dass die Randbereiche der die Wandöffnung umgebenden Möbelwand übergriffen wird. Der am Einsteckrahmen vorgesehene Rückhaltevorsprung besteht zweckmäßigerweise aus einer über die Deckenwand des Einsteckrahmens nach oben vorstehenden Rastnase mit Anlaufschräge, so dass der Einsteckrahmen clipartig an der Möbelwand verrastet werden kann.Advantageously, the plug-in frame has an outer stop which bears against the outside of the furniture wall when the plug-in frame is inserted, and at least one retaining projection which engages behind the furniture wall in the inserted state of the plug-in frame in such a way that it is prevented from moving against the direction of insertion. The one on the outside of the Furniture wall that can be brought into contact with the outer stop expediently consists of the front end wall of the plug-in frame, which projects laterally and upwards beyond the side walls or top wall of the plug-in frame so that the edge areas of the furniture wall surrounding the wall opening are overlapped. The retaining projection provided on the plug-in frame expediently consists of a locking lug projecting upward above the ceiling wall of the plug-in frame, with a bevel so that the plug-in frame can be locked in a clip-like manner on the furniture wall.

Gemäß einer vorteilhaften Ausführungsform weist der Einsteckrahmen bodenseitig einen Spalt oder ein definierten Brückenelement mit Solltrennstelle zur Bildung eines Spaltes auf, durch den ein Kabel in den Einsteckrahmen einführbar ist. Ein derartiger Spalt ist immer dann vorteilhaft, wenn die Höhe des Einsteckrahmens nicht ausreicht, um einen Kabelstecker in Längsrichtung des Kabeldurchführraums hindurchführen zu können. Der Brückenbereich stabilisiert im intakten Zustand die Bodenwand des Einsteckrahmens und ermöglicht andererseits ein einfaches Herstellen des Spalts, falls dies erforderlich sein sollte.According to an advantageous embodiment, the plug-in frame has a gap on the bottom or a defined bridge element with a predetermined separation point to form a gap through which a cable can be inserted into the plug-in frame. Such a gap is always advantageous when the height of the plug-in frame is not sufficient to be able to pass a cable plug in the longitudinal direction of the cable lead-through space. The bridge area stabilizes the base wall of the plug-in frame when intact and, on the other hand, enables the gap to be easily produced if this should be necessary.

Vorteilhafterweise umfasst die Formschlussverbindungseinrichtung, die zwischen dem Einsteckrahmen und der Kabelzugentlastungseinrichtung vorgesehen ist, Stege, die von Seitenwänden des Einsteckrahmens in den Kabeldurchgangsraum hinein vorstehen, und Nuten, die an der Kabelzugentlastungseinrichtung angeordnet und in Eingriff mit den Stegen bringbar sind. Die Stege und Nuten sind dabei derart angeordnet, dass die Kabelzugentlastungseinrichtung an einer bestimmten Stelle des Einsteckrahmens in diesen eingeführt und durch eine weitere Bewegung dann derart im Einsteckrahmen verlagert werden kann, dass sie in Längsrichtung des Kabels nicht mehr aus dem Einsteckrahmen und damit nicht mehr aus der Sockelleiste herausgezogen werden kann.Advantageously, the interlocking connection device which is provided between the plug-in frame and the cable strain relief device comprises webs which protrude from side walls of the plug-in frame into the cable passage space, and grooves which are arranged on the cable strain relief device and can be brought into engagement with the webs. The webs and grooves are arranged such that the cable strain relief device inserted at a certain point in the plug-in frame and then moved by a further movement in the plug-in frame in such a way that it can no longer be pulled out of the plug-in frame in the longitudinal direction of the cable and thus no longer be pulled out of the baseboard.

Vorteilhafterweise bestehen die Stege des Einsteckrahmens aus an der Innenseite der Seitenwände des Einsteckrahmens angeordneten vertikalen Steg mit einem oberen Ende, das zur Deckenwand des Einführrahmens beabstandet ist, so dass zwischen Steg und Deckenwand ein Einführspalt vorhanden ist. Weiterhin umfasst die Formschlussverbindungseinrichtung vorteilhafterweise an der Kabelzugentlastungeinrichtung vorgesehene seitliche Halteleisten, in denen Führungsnuten vorgesehen ist, die zum Halteingriff mit den Stegen ausgebildet sind. Hierdurch ist es möglich, die Kabelzugentlastungseinrichtung in einer erhöhten Stellung in den Einführspalt zwischen Vertikalsteg und Deckenwand des Einsteckrahmens in den Einsteckrahmen einzuführen, bis die Nuten der Kabelzugentlastungseinrichtung mit den vertikalen Stegen fluchten, und anschließend die Kabelzugentlastungseinrichtung abzusenken, wodurch die Stege in die Nuten eingreifen.The webs of the plug-in frame advantageously consist of vertical webs arranged on the inside of the side walls of the plug-in frame and having an upper end which is spaced apart from the top wall of the insertion frame, so that an insertion gap is present between the web and the top wall. Furthermore, the positive-locking connection device advantageously comprises lateral holding strips provided on the cable strain relief device, in which guide grooves are provided, which are designed for holding engagement with the webs. This makes it possible to insert the cable strain relief device in an elevated position into the insertion gap between the vertical web and the top wall of the plug-in frame until the grooves of the cable strain relief device are aligned with the vertical webs, and then to lower the cable strain relief device, as a result of which the webs engage in the grooves.

Vorteilhafterweise umfasst die Kabelzugentlastungseinrichtung ein Oberteil und ein Unterteil, zwischen denen mindestens ein Kabel festklemmbar ist, wobei das Oberteil Seitenwände und eine plattenförmige Deckenwand aufweist, die seitlich über die Seitenwände vorsteht und die Halteleisten bildet.Advantageously, the cable strain relief device comprises an upper part and a lower part, between which at least one cable can be clamped, the upper part having side walls and a plate-shaped ceiling wall which protrudes laterally beyond the side walls and forms the retaining strips.

In Figur 1 ist ein erfindungsgemäßes Möbel mit einem Möbelkorpus 2 und einer bodenseitigen Sockelleiste 3 dargestellt. Im gezeigten Ausführungsbeispiel ist das Möbel 1 kastenartig, wobei der Möbelkorpus 2 eine vordere Wand 4, zwei Seitenwände 5, einen Boden 6, eine obere Wand 7 und eine in Figur 1 verdeckt dargestellte Rückwand aufweist. Gemäß dem in Figur 1 dargestellten Ausführungsbeispiel ist der Möbelkorpus 2 auf seiner Vorderseite überwiegend offen. Art, Formgebung und Funktionalität des Möbels 1 sind im Rahmen der vorliegenden Erfindung jedoch im weiten Umfang variierbar und in keiner Weise auf das dargestellte Ausführungsbeispiel beschränkt.In Figure 1 A piece of furniture according to the invention is shown with a furniture body 2 and a bottom skirting board 3. In the exemplary embodiment shown, the furniture 1 is box-like, the furniture body 2 having a front wall 4, two side walls 5, a bottom 6, an upper wall 7 and one in Figure 1 has hidden rear wall. According to the in Figure 1 illustrated embodiment, the furniture body 2 is largely open on its front. The type, shape and functionality of the furniture 1 can, however, be varied within the scope of the present invention and are in no way limited to the exemplary embodiment shown.

Die im Randbereich des Bodens 6 vorzugsweise vollständig umlaufende Sockelleiste 3 besteht zumindest überwiegend aus einem Metallblech. Die Sockelleiste 3 kann derart ausgebildet sein, dass sie den Möbelkorpus 2 trägt, oder kann, wenn der Möbelkorpus 2 auf separaten, nicht dargestellten Füßen ruht, lediglich eine Sockelblende ohne tragende Funktion sein. Als Sockelleisten werden im Rahmen der vorliegenden Erfindung somit sowohl tragende Sockelleisten als auch nicht tragende Sockelblenden verstanden.The skirting board 3, which is preferably completely circumferential in the edge region of the base 6, consists at least predominantly of a metal sheet. The skirting board 3 can be designed in such a way that it supports the furniture body 2, or, if the furniture body 2 rests on separate feet (not shown), it can only be a base panel without a supporting function. In the context of the present invention, skirting boards are understood to mean both supporting skirting boards and non-supporting skirting boards.

Die Sockelleiste 3 weist eine vertikale Sockelleistenwand 8 auf, die aus einem Material besteht, das durch Biegen umgeformt werden kann. Zweckmäßigerweise besteht die Sockelleistenwand 8 aus einem Metallblech.The skirting board 3 has a vertical skirting board wall 8, which consists of a material that can be deformed by bending. The skirting board wall 8 expediently consists of a metal sheet.

Die Sockelleistenwand 8 weist auf jeder Seite des Möbels 1 einen Abschnitt 9 auf, der zur Bildung einer Kabeldurchführung 10 bestimmt ist. Diese Abschnitte 9 können auf jeder Seite des Möbels 1 oder nur auf bestimmten Seiten, insbesondere auf der Rückseite des Möbels 1, angeordnet sein. Weiterhin ist es auch ohne weiteres möglich, dass auf einer oder mehreren Seiten des Möbels 1 mehrere Abschnitte 9 vorgesehen sind. Weiterhin ist es auch möglich, dass derartige Abschnitte 9 nicht oder nicht nur in der Sockelleistenwand 8 vorgesehen sind, sondern in einer anderen Wand des Möbels 1, wenn diese Wand aus einem Material besteht, das durch Biegen umgeformt werden kann. Eine derartige Wand, insbesondere die Sockelleistenwand 8, wird im Folgenden daher allgemeiner auch als Möbelwand 11 bezeichnet.The skirting board wall 8 has a section 9 on each side of the furniture 1, which section is intended to form a cable bushing 10. These sections 9 can be arranged on each side of the furniture 1 or only on certain sides, in particular on the back of the furniture 1. Furthermore, it is also readily possible for a plurality of sections 9 to be provided on one or more sides of the furniture 1. Furthermore, it is also possible that such sections 9 are not provided or not only in the skirting board wall 8, but in another wall of the furniture 1 if this wall consists of a material that can be deformed by bending. Such a wall, in particular the skirting board wall 8, is therefore more generally referred to below as a furniture wall 11.

Figur 2 zeigt einen Abschnitt der Sockelleiste 3 in Alleinstellung im Bereich eines Abschnitts 9, der zur Bildung einer Kabeldurchführung 10 bestimmt ist. Der Abschnitt 9 umfasst zwei Biegelaschen 12a, 12b, die jeweils durch einen teilweise freigeschnittenen Abschnitt der Möbelwand 11 gebildet werden. Hierzu sind die Biegelaschen 12a, 12b jeweils durch einen seitlich außenliegenden, vertikalen Längsschlitz 13a, 13b und durch einen oberen, durchgehenden, horizontalen Längsschlitz 14 über den überwiegenden Teil ihrer Umfänge von den angrenzenden Randbereichen der Möbelwand 11 getrennt. Weiterhin sind die beiden nebeneinanderliegenden Biegelaschen 12a, 12b durch einen mittigen vertikalen Längsschlitz 15 über den überwiegenden Teil ihrer Höhe voneinander getrennt. Die seitlichen vertikalen Längsschlitze 13a, 13b weisen eine derartige Länge auf, dass zwischen dem unteren Ende der vertikalen Längsschlitze 13a, 13b und dem unteren Rand der Biegelaschen 12a, 12b lediglich ein relativ schmaler Brückenabschnitt 16a, 16b oder Steg vorhanden ist. Zwischen dem oberen Ende der vertikalen Längsschlitze 13a, 13b und dem horizontalen Längsschlitz 14 ist lediglich ein schmaler Brückenabschnitt 17a, 17b oder Steg vorhanden. Weiterhin sind die beiden Biegelaschen 12a, 12b in der in Figur 2 gezeigten Ausgangsstellung, in der sie mit den angrenzenden Bereichen der Möbelwand 11 fluchten, durch obere und untere Verbindungsabschnitte 18 miteinander verbunden, die sich vom oberen Ende des mittigen vertikalen Längsschlitzes 15 bis zum horizontalen Längsschlitz 15 bzw. vom unteren Ende des mittigen vertikalen Längsschlitzes 15 bis zum unteren Rand der Biegelaschen 12a, 12b erstrecken. Diese Verbindungsabschnitte 18 bilden eine Solltrennlinie und können derart ausgebildet sein, dass sie auf einfache Weise durchtrennt werden können, beispielsweise indem sie eine geringere Wandstärke aufweisen als die Biegelaschen 12a, 12b. Die Längsschlitze 13a, 13b, 14 werden zweckmäßigerweise durch Ausstanzen der im Ausgangszustand ebenen, durchgängigen Möbelwand 11 gebildet. Figure 2 shows a section of the skirting board 3 in isolation in the area of a section 9, which is intended to form a cable bushing 10. The section 9 comprises two bending tabs 12a, 12b, which are each formed by a partially cut-out section of the furniture wall 11. For this purpose, the bending tabs 12a, 12b are each separated from the adjacent edge regions of the furniture wall 11 by a vertical longitudinal slot 13a, 13b located on the outside and by an upper, continuous, horizontal longitudinal slot 14 over the majority of their circumferences. Furthermore, the two adjacent bending tabs 12a, 12b are separated from one another by a central vertical longitudinal slot 15 over the major part of their height. The lateral vertical longitudinal slots 13a, 13b have a length such that between the lower end of the vertical longitudinal slots 13a, 13b and the lower one Edge of the bending tabs 12a, 12b only a relatively narrow bridge section 16a, 16b or web is present. There is only a narrow bridge section 17a, 17b or web between the upper end of the vertical longitudinal slots 13a, 13b and the horizontal longitudinal slot 14. Furthermore, the two bending tabs 12a, 12b in the in Figure 2 Starting position shown, in which they are aligned with the adjacent areas of the furniture wall 11, connected to one another by upper and lower connecting sections 18, which extend from the upper end of the central vertical longitudinal slot 15 to the horizontal longitudinal slot 15 and from the lower end of the central vertical longitudinal slot 15 to extend to the lower edge of the bending tabs 12a, 12b. These connecting sections 18 form a predetermined dividing line and can be designed such that they can be severed in a simple manner, for example by having a smaller wall thickness than the bending tabs 12a, 12b. The longitudinal slots 13a, 13b, 14 are expediently formed by punching out the continuous furniture wall 11 which is flat in the initial state.

Aufgrund der Längsschlitze 13a, 13b, 14 ist es möglich, nach dem Durchtrennen der Verbindungsabschnitte 18 die Biegelaschen 12a, 12b auf einfache Weise nach innen umzubiegen, wobei die Biegelaschen um die im Bereich der vertikalen Längsschlitze 13a, 13b liegenden vertikalen Schwenkachsen geschwenkt und die Brückenabschnitte 16a, 17a bzw. 16b, 17b entsprechend umgebogen werden. Zweckmäßigerweise werden die Biegelaschen 12a, 12b derart nach innen umgebogen, dass sie in einem Winkel von 90° zu den angrenzenden Bereichen der Möbelwand 11 angeordnet sind.Due to the longitudinal slots 13a, 13b, 14 it is possible, after severing the connecting sections 18, to bend the bending tabs 12a, 12b inwards in a simple manner, the bending tabs being pivoted about the vertical pivot axes lying in the region of the vertical longitudinal slots 13a, 13b and the bridge sections 16a, 17a and 16b, 17b are bent accordingly. The bending flaps 12a, 12b are expediently bent inwards in such a way that they are arranged at an angle of 90 ° to the adjacent areas of the furniture wall 11.

Aus den Figuren 1 und 2 ist erkennbar, dass die Möbelwand 11 in ihrem Ausgangszustand, d.h. so lange die Biegelaschen 12a, 12b nicht umgebogen sind, mit Ausnahme der Längsschlitze 13a, 13b, 14 geschlossen bleibt, da sich die Biegelaschen 12a, 12b in diesem Zustand noch in der Hauptebene der Möbelwand 11 befinden.From the Figures 1 and 2 It can be seen that the furniture wall 11 remains closed in its initial state, ie as long as the bending tabs 12a, 12b are not bent, with the exception of the longitudinal slots 13a, 13b, 14, since the bending tabs 12a, 12b in this state still remain in the main plane of the Furniture wall 11 are.

Die Biegelaschen 12a, 12b sind quadratisch oder rechteckig ausgebildet und erstrecken sich im gezeigten Ausführungsbeispiel vom unteren Rand 19 der Sockelleiste 3 über den überwiegenden Teil der Höhe der Sockelleiste 3. Die Höhe und Breite der Biegelaschen 12a, 12b kann jedoch in weitem Umfang variieren.The bending tabs 12a, 12b are square or rectangular in shape and, in the exemplary embodiment shown, extend from the lower edge 19 of the skirting board 3 over most of the height of the skirting board 3. However, the height and width of the bending tabs 12a, 12b can vary widely.

Soll im Bereich der Biegelaschen 12a, 12b eine Kabeldurchführung 10 (Figur 5) installiert werden, um ein Kabel 21 durch die Sockelleiste 3 hindurch zu führen, werden die Verbindungsabschnitte 18, beispielsweise mittels einer Säge oder Blechschere, durchtrennt, wodurch die Biegelaschen 12a, 12b nach innen umgebogen werden können.If in the area of the bending tabs 12a, 12b a cable bushing 10 ( Figure 5 ) are installed in order to lead a cable 21 through the baseboard 3, the connecting sections 18 are severed, for example by means of a saw or sheet metal shears, as a result of which the bending tabs 12a, 12b can be bent inwards.

Figur 3 zeigt die Biegelaschen 12a, 12b in ihrer nach innen umgebogenen Öffnungsstellung, in der sie türflügelartig geöffnet sind. In dieser Öffnungsstellung begrenzen die Biegelaschen 12a, 12b seitlich eine Wandöffnung 20 in der Sockelleiste 3. Figure 3 shows the bending tabs 12a, 12b in their inwardly bent open position, in which they are opened like a door leaf. In this open position, the bending tabs 12a, 12b laterally delimit a wall opening 20 in the baseboard 3.

Diese Wandöffnung 20 dient zum Einstecken eines hülsenförmigen Einsteckrahmens, der die Wandöffnung 20 auskleidet. Der Einsteckrahmen 22 besteht zweckmäßigerweise aus einem einstückigen Kunststoffteil. Andere Materialien und ein aus mehreren Teilen zusammengesetzter Einsteckrahmen 22 sind ebenfalls möglich.This wall opening 20 is used to insert a sleeve-shaped plug-in frame that lines the wall opening 20. The plug-in frame 22 expediently consists of a one-piece plastic part. Other materials and a plug-in frame 22 composed of several parts are also possible.

Der Einsteckrahmen 22 umfasst Seitenwände 23, einen Boden 24, eine Deckenwand 25 und eine äußere Stirnwand 26, die seitlich und nach oben über die Seitenwände 23 bzw. Deckenwand 25 vorsteht. Die Breite des Einsteckrahmens 22 ist im Bereich der Seitenwände 23 so bemessen, dass diese, wenn der Einsteckrahmen 22 in die Wandöffnung 20 eingesteckt wird, an den umgebogenen Biegelaschen 12a, 12b anliegen.The plug-in frame 22 comprises side walls 23, a bottom 24, a top wall 25 and an outer end wall 26 which projects laterally and upwards over the side walls 23 and top wall 25. The width of the plug-in frame 22 is dimensioned in the region of the side walls 23 such that when the plug-in frame 22 is inserted into the wall opening 20, they rest on the bent bending tabs 12a, 12b.

Der Einsteckrahmen 22 weist ferner, wie aus den Figuren 3 und 4 ersichtlich, seitlich nach außen über die Seitenwände 23 vorspringende obere Stege 27 und untere Stege 28 auf. Die oberen Stege 27 werden durch eine seitliche Verlängerung der Deckenwand 25 gebildet, während die unteren Stege 28 durch eine seitliche Verlängerung des Bodens 24 gebildet werden. Zweckmäßigerweise erstrecken sich die Stege 27, 28 über die gesamte Tiefe oder zumindest über den überwiegenden Teil der Tiefe des Einsteckrahmens 22, wodurch eine besonders gute Stützwirkung erzielt werden kann.The insertion frame 22 also has, as from the Figures 3 and 4 It can be seen that upper webs 27 and lower webs 28 project laterally outwards over the side walls 23. The upper webs 27 are formed by a lateral extension of the ceiling wall 25, while the lower webs 28 are formed by a lateral extension of the bottom 24. The webs 27, 28 expediently extend over the entire depth or at least over the major part of the depth of the insertion frame 22, as a result of which a particularly good support effect can be achieved.

Da ein oberer Rand 29a, 29b (Figur 2) der Biegelaschen 12a, 12b aufgrund des horizontalen Längsschlitzes 14 in vertikaler Richtung zur angrenzenden Möbelwand 11 beabstandet ist, wird ein Zwischenraum 30 gebildet, der nach dem Umbiegen der Biegelaschen 12a, 12b seitliche Nuten 31a, 31b (Figur 3) zwischen den oberen Brückenabschnitten 17a, 17b und dem oberen Rand 32 der Wandöffnung ergibt. In diese seitlichen Nuten 31a, 31b greifen die oberen Stege 27 des Einsteckrahmens 22 ein. Gleichzeitig übergreifen die oberen Stege 27, wie insbesondere aus den Figuren 4 und 6 ersichtlich, die Biegelaschen 12a, 12b. Die unteren Stege 28 des Einsteckrahmens 22 untergreifen die Biegelaschen 12a, 12b. Die Biegelaschen 12a, 12b stützen damit den Einsteckrahmen 22 nach oben und unten ab, was wesentlich zu einem festen, zuverlässigen Sitz des Einsteckrahmens 22 innerhalb der Wandöffnung 20 beiträgt.Since an upper edge 29a, 29b ( Figure 2 ) of the bending flaps 12a, 12b due to the horizontal longitudinal slot 14 in the vertical direction to the adjacent furniture wall 11, an intermediate space 30 is formed which, after the bending of the bending flaps 12a, 12b, lateral grooves 31a, 31b ( Figure 3 ) between the upper bridge sections 17a, 17b and the upper edge 32 of the wall opening. The upper webs 27 of the plug-in frame 22 engage in these lateral grooves 31a, 31b. At the same time overlap the upper webs 27, as in particular from the Figures 4 and 6 can be seen the bending tabs 12a, 12b. The lower webs 28 of the insertion frame 22 engage under the bending tabs 12a, 12b. The bending tabs 12a, 12b thus support the insertion frame 22 upwards and downwards, which contributes significantly to a firm, reliable fit of the insertion frame 22 within the wall opening 20.

Die Breite der Biegelaschen 12a, 12b und die Tiefe des Einsteckrahmens 22 sind zweckmäßigerweise derart aufeinander abgestimmt, dass sich die umgebogenen Biegelaschen 12a, 12b zumindest über den ganz überwiegenden Teil der Tiefe des Einsteckrahmens 22 erstrecken.The width of the bending tabs 12a, 12b and the depth of the insertion frame 22 are expediently coordinated with one another in such a way that the bent bending tabs 12a, 12b extend at least over the vast majority of the depth of the insertion frame 22.

Der Einsteckrahmen 22 wird soweit in die Wandöffnung 22 eingesteckt, bis die Stirnwand 26 an der Außenseite der Möbelwand 11 anschlägt. Die Stirnwand 26 steht somit über den Rand der Wandöffnung 20 vor und bildet einen äußeren Anschlag zur Begrenzung des Einschubwegs des Einsteckrahmens 22. Weiterhin ist an der Deckenwand 25 des Einsteckrahmens 22 ein Rückhaltevorsprung 33 ausgebildet, der im eingesteckten Zustand des Einsteckrahmens 22 die Möbelwand 11 derart hintergreift, dass ein Verschieben des Einsteckrahmens 22 entgegen der Einsteckrichtung verhindert wird. Um ein einfaches Einschieben des Einsteckrahmens 22 zu ermöglichen, ist der Rückhaltevorsprung 33 keilförmig mit einer Anlaufschräge ausgebildet. Im gezeigten Ausführungsbeispiel ist der Rückhaltevorsprung 33 mittig am Einsteckrahmen 22 angeordnet. Andere Ausbildungen des Rückhaltevorsprungs 33 sind ohne weiteres möglich, beispielsweise stabile, jedoch federnd nachgiebige Federzungen. Anstelle eines einzelnen mittigen Rückhaltevorsprungs 33 können auch zwei oder mehr Rückhaltevorsprünge vorgesehen sein, die über die Breite des Einsteckrahmens 22 verteilt angeordnet sind.The insert frame 22 is inserted into the wall opening 22 until the end wall 26 strikes the outside of the furniture wall 11. The end wall 26 thus protrudes over the edge of the wall opening 20 and forms an outer stop to limit the insertion path of the plug-in frame 22. Furthermore, a retaining projection 33 is formed on the top wall 25 of the plug-in frame 22, which in the inserted state of the plug-in frame 22 has the furniture wall 11 in this way engages behind that a displacement of the insertion frame 22 against the insertion direction is prevented. In order to enable easy insertion of the insertion frame 22, the retaining projection 33 is wedge-shaped with a run-on slope. In the exemplary embodiment shown, the retaining projection 33 is arranged centrally on the plug-in frame 22. Other designs of the retaining projection 33 are readily possible, for example stable but resilient spring tongues. Instead of one central retaining projection 33, two or more retaining projections can also be provided, which are arranged distributed over the width of the plug-in frame 22.

Der Einsteckrahmen 22 kann werkzeuglos in die Sockelleiste 3 eingeclipst werden und wird, da er zwischen vorderer Stirnwand 26 und Rückhaltevorsprung 33 an der Möbelwand 11 und zusätzlich durch die Biegelaschen 12a, 12b seitlich abgestützt wird, fest und zuverlässig an der Sockelleiste 3 gehalten.The plug-in frame 22 can be clipped into the skirting board 3 without tools and, since it is supported laterally on the furniture wall 11 between the front end wall 26 and the retaining projection 33 and additionally by the bending tabs 12a, 12b, is held firmly and reliably on the skirting board 3.

Der Boden 24 des Einsteckrahmens 22 ist in zwei Bodenabschnitte 24a, 24b unterteilt, die sich von den Seitenwänden 23 aufeinander zu erstrecken. Die Bodenabschnitte 24a, 24b sind jedoch zueinander beabstandet, so dass ein in der Mitte des Einsteckrahmens 22 liegender Spalt 34 gebildet wird, der lediglich von einem Brückenelement 35 mit reduzierter Wanddicke überbrückt wird. Das Brückenelement 35 ist hierbei derart ausgebildet, dass es auf einfache Weise durchtrennt werden kann, um bei Bedarf das Kabel 21 von unten her durch den Spalt 34 hindurch in einen vom Einsteckrahmen 22 umschlossenen Kabeldurchgangsraum 36 einzuführen. Ist das Durchtrennen des Brückenelements 35 nicht erforderlich, da der Einsteckrahmen 22 ausreichend groß dimensioniert ist, stabilisiert das Brückenelement 35 den Boden 24, da dann der Einsteckrahmen 22 in Umfangsrichtung geschlossen umlaufend ausgebildet ist.The bottom 24 of the plug-in frame 22 is divided into two bottom sections 24a, 24b, which extend from the side walls 23 towards one another. However, the bottom sections 24a, 24b are spaced apart from one another, so that a gap 34 is formed in the middle of the plug-in frame 22 and is only bridged by a bridge element 35 with a reduced wall thickness. The bridge element 35 is designed in such a way that it can be severed in a simple manner in order, if necessary, to insert the cable 21 from below through the gap 34 into a cable passage space 36 enclosed by the plug-in frame 22. If it is not necessary to cut through the bridge element 35, since the plug-in frame 22 is of sufficiently large dimensions, the bridge element 35 stabilizes the base 24, since the plug-in frame 22 is then designed to be closed all around in the circumferential direction.

Der Einsteckrahmen 22 dient zum Aufnehmen und festen Halten einer Kabelzugentlastungseinrichtung 37, die in Figur 3 in Explosionsdarstellung und in den Figuren 4 bis 6 im montierten Zustand dargestellt ist. Wie insbesondere aus Figur 3 ersichtlich, umfasst die Kabelzugentlastungseinrichtung 37 ein Oberteil 38 und ein Unterteil 39. Oberteil 38 und Unterteil 39 bestehen aus zwei separaten Bauteilen, die voneinander gelöst und mittels einer Schraube 40 miteinander verbunden werden können. Weiterhin sind Oberteil 38 und Unterteil 39 jeweils schalenförmig ausgebildet. In den vorderen und hinteren Wänden des Oberteils 38 und Unterteils 39 sind jeweils halbkreisförmige Aussparungen 41, 42 vorgesehen, die sich bei zusammengebauten Oberteil 38 und Unterteil 39 zu kreisförmigen Aussparungen ergänzen, um darin Kabel 21 aufzunehmen und festzuklemmen. Im gezeigten Ausführungsbeispiel ist die Kabelzugentlastungseinrichtung 37 zur Aufnahme und zum Festklemmen von drei nebeneinander angeordneten Kabeln ausgebildet. Die Anzahl der Kabeldurchlässe pro Kabelzugentlastungseinrichtung ist jedoch variabel und kann auch lediglich ein oder zwei Kabeldurchlässe oder mehr als drei Kabeldurchlässe umfassen. Sind Oberteil 38 und Unterteil 39 mittels der Schraube 40 miteinander verschraubt, wird das hindurchgeführte Kabel 21 fest innerhalb der Kabelzugentlastungseinrichtung 37 eingeklemmt, d.h. die Kabelzugentlastungseinrichtung 37 wird dann fest am Kabel 21 verankert.The plug-in frame 22 is used to hold and hold a cable strain relief device 37, which in Figure 3 in exploded view and in the Figures 4 until 6 is shown in the assembled state. How especially out Figure 3 As can be seen, the cable strain relief device 37 comprises an upper part 38 and a lower part 39. Upper part 38 and lower part 39 consist of two separate components which can be detached from one another and connected to one another by means of a screw 40. Furthermore, the upper part 38 and lower part 39 are each bowl-shaped. In the front and rear walls of the upper part 38 and lower part 39, semicircular cutouts 41, 42 are provided, which, when the upper part 38 and lower part 39 are assembled, form circular cutouts in order to receive and clamp cables 21 therein. In the exemplary embodiment shown, the cable strain relief device 37 is designed to receive and clamp three cables arranged next to one another. However, the number of cable passages per cable strain relief device is variable and can also comprise only one or two cable passages or more than three cable passages. If the upper part 38 and lower part 39 are screwed together by means of the screw 40, the cable 21 passed through is firmly clamped inside the cable strain relief device 37, ie the cable strain relief device 37 is then firmly anchored to the cable 21.

Die Kabelzugentlastungseinrichtung 37 hat im zusammengebauten Zustand im Wesentlichen die Form eines Quaders, wobei die Deckenwand 43 des Oberteils 38 und der Boden 44 des Unterteils 39 eben ausgebildet sind.In the assembled state, the cable strain relief device 37 has essentially the shape of a cuboid, the top wall 43 of the upper part 38 and the bottom 44 of the lower part 39 being flat.

Die Kabelzugentlastungseinrichtung 37 ist im dargestellten Ausführungsbeispiel ausschließlich formschlüssig und werkzeuglos innerhalb des Einsteckrahmens 22 verankerbar. Die Formschlussverbindung zwischen Einsteckrahmen 22 und Kabelzugentlastungseinrichtung 37 umfasst einsteckrahmenseitig vertikale Stege 45, die von den Seitenwänden 23 des Einsteckrahmens 22 nach innen vorstehen. Im gezeigten Ausführungsbeispiel sind an jeder Seitenwand 23 zwei zueinander parallele Stege 45 vorgesehen. Die Anzahl der Stege 45 kann jedoch variieren und beispielsweise auch nur einen Steg 45 oder drei Stege 45 pro Seitenwand 23 betragen.The cable strain relief device 37 is only positive and in the illustrated embodiment can be anchored without tools within the plug-in frame 22. The interlocking connection between the plug-in frame 22 and the cable strain relief device 37 comprises vertical webs 45 on the plug-in frame side, which protrude inwards from the side walls 23 of the plug-in frame 22. In the exemplary embodiment shown, two mutually parallel webs 45 are provided on each side wall 23. However, the number of webs 45 can vary and, for example, can also be only one web 45 or three webs 45 per side wall 23.

Die Stege 45 erstrecken sich, wie aus Figur 3 ersichtlich, nach unten bis zu den Bodenabschnitten 24a, 24b. Nach oben erstrecken sich die Stege 45 dagegen nicht ganz bis zur Deckenwand 25, sondern weisen zu dieser einen Abstand auf. Dieser Abstand ist so bemessen, dass er geringfügig größer ist als die Dicke von seitlichen Halteleisten 46, die in den Seitenbereichen des Oberteils 38 der Kabelzugentlastungseinrichtung 37 vorgesehen sind.The webs 45 extend as from Figure 3 can be seen down to the bottom portions 24a, 24b. In contrast, the webs 45 do not extend all the way up to the ceiling wall 25, but are at a distance from this. This distance is dimensioned such that it is slightly larger than the thickness of lateral retaining strips 46 which are provided in the side regions of the upper part 38 of the cable strain relief device 37.

Diese Halteleisten 46 werden im gezeigten Ausführungsbeispiel durch eine seitliche Verlängerung der Deckenwand 43 des Oberteils 38 gebildet, die über die Seitenwände 47 des Oberteils 38 seitlich nach außen vorstehen. In den seitlichen Halteleisten 46 sind jeweils zwei Führungsnuten 48 vorgesehen, die an die Stege 45 des Einsteckrahmens 22 angepasst sind. Aufgrund dieser Ausbildung kann die Kabelzugentlastungseinrichtung 37 in einer erhöhten Position, in der sie sich unmittelbar unterhalb der Deckenwand 25 des Einsteckrahmens 22 befindet, in den Einsteckrahmen 22 eingeführt werden, bis die Führungsnuten 48 mit den Stegen 45 fluchten. Wird anschließend die Kabelzugentlastungseinrichtung 37 abgesenkt, greifen die Stege 45 in die Führungsnuten 48 ein, wodurch ein Verschieben der Kabelzugentlastungseinrichtung 37 in Längsrichtung des Kabeldurchgangsraums 36 blockiert ist und eine sichere Zugentlastung für das Kabel 21 im Bereich der Sockelleiste 3 geschaffen wird.In the exemplary embodiment shown, these holding strips 46 are formed by a lateral extension of the top wall 43 of the upper part 38, which project laterally outwards via the side walls 47 of the upper part 38. Two guide grooves 48 are provided in each of the lateral holding strips 46, which are adapted to the webs 45 of the plug-in frame 22. Due to this design, the cable strain relief device 37 can be inserted into the insertion frame 22 in an elevated position, in which it is located directly below the ceiling wall 25 of the insertion frame 22, until the guide grooves 48 are aligned with the webs 45. Will then the cable strain relief device 37 is lowered, the webs 45 engage in the guide grooves 48, as a result of which a displacement of the cable strain relief device 37 in the longitudinal direction of the cable passage space 36 is blocked and a secure strain relief for the cable 21 in the region of the baseboard 3 is created.

Die Abschnitte 9 der Sockelleiste 3 bilden somit mit dem Einsteckrahmen 22 und der Kabelzugentlastungseinrichtung 37 eine Kabeldurchführung 10 für die Sockelleiste 3, die nach dem Umbiegen der Biegelaschen 12a, 12b ein einfaches, sicheres und werkzeugloses Festlegen der Kabelzugentlastungseinrichtung 37 an der Sockelleiste 3 ermöglicht.The sections 9 of the skirting board 3 thus form, with the plug-in frame 22 and the cable strain relief device 37, a cable bushing 10 for the skirting board 3, which, after the bending flaps 12a, 12b have been bent over, enables the cable strain relief device 37 to be simply, securely and without tools on the skirting board 3.

In den Figuren 5 und 6 ist die Kabeldurchführung 10 mit festgeklemmtem Kabel 21 im fertig montierten Zustand dargestellt.In the Figures 5 and 6 the cable bushing 10 is shown with clamped cable 21 in the fully assembled state.

Anhand der Figuren 7 bis 12 wird im Folgenden das Verfahren zur Ausbildung einer derartigen Kabeldurchführung 10 beschrieben.Based on Figures 7 to 12 The method for forming such a cable bushing 10 is described below.

Wie aus Figur 7 ersichtlich, wird zunächst ein Möbel 1 mit einer Sockelleiste 3 bereitgestellt, die vorzugsweise eine Mehrzahl von an verschiedenen Stellen der Sockelleiste 3 vorgesehenen, teilweise frei geschnittenen Abschnitten 9 für die Ausbildung einer Kabeldurchführung 10 aufweist. In Figur 7 ist der rechte Abschnitt 9 im Ausgangszustand dargestellt, in dem die Biegelaschen 12a, 12b mit der angrenzenden Sockelleistenwand 8 bzw. Möbelwand 11 fluchten. Der linke Abschnitt 9 ist dagegen in einem Zustand dargestellt, in dem die Biegelaschen 12a, 12b quer zur Sockelleistenwand 8 bzw. Möbelwand 11 nach innen eingebogen sind, wodurch eine Wandöffnung 20 in der Sockelleiste 3 geschaffen wird. Um das Umbiegen der Biegelaschen 12a, 12b zu ermöglichen, werden die Verbindungsabschnitte 18 zwischen den Biegelaschen 12a, 12b durchtrennt.How from Figure 7 As can be seen, a piece of furniture 1 is initially provided with a baseboard 3, which preferably has a plurality of partially free-cut sections 9 provided at different locations on the baseboard 3 for the formation of a cable duct 10. In Figure 7 the right section 9 is shown in the initial state, in which the bending tabs 12a, 12b are aligned with the adjoining skirting board wall 8 or furniture wall 11. The left section 9, however, is shown in a state in which the bending tabs 12a, 12b are bent inwards transversely to the skirting board wall 8 or furniture wall 11, as a result of which a wall opening 20 is created in the skirting board 3. In order to allow the bending tabs 12a, 12b to be bent, the connecting sections 18 between the bending tabs 12a, 12b are severed.

Nach dem Herstellen der Wandöffnung 20 wird, wie aus Figur 8 ersichtlich, der Einsteckrahmen 22 von außen her, beispielsweise von der Rückseite des Möbels 1 her, an die Wandöffnung 20 herangeführt und in diese eingesteckt, bis die Stirnwand 26 des Einsteckrahmens 22 an der Sockelleistenwand 8 / Möbelwand 11 anliegt und der Rückhaltevorsprung 33 den angrenzenden Bereich der Sockelleistenwand 8 / Möbelwand 11 hitergreift. Der Einsteckrahmen 22 wird dabei mit dem den Einsteckrahmen 22 umgebenden Randbereich der Sockelleistenwand 8 / Möbelwand 11 und mit den Biegelaschen 12a, 12b in Halteeingriff gebracht.After the wall opening 20 has been produced, as can be seen in FIG. 8, the plug-in frame 22 is guided from the outside, for example from the rear of the furniture 1, to the wall opening 20 and inserted into the latter until the end wall 26 of the plug-in frame 22 on the skirting board wall 8 / furniture wall 11 abuts and the retaining projection 33 hits the adjacent area of the skirting board wall 8 / furniture wall 11. The plug-in frame 22 is brought into holding engagement with the edge region of the skirting board wall 8 / furniture wall 11 surrounding the plug-in frame 22 and with the bending tabs 12a, 12b.

Anschließend wird, wie aus Figur 10 ersichtlich, das Kabel 21 durch den Einsteckrahmen 22 hindurch geführt. Falls das Kabel 21 kein Endteil aufweist, das größer ist als die innere Durchgangsweite des Einsteckrahmens 22, ist es nicht erforderlich, das Brückenelement 35 zwischen den Bodenabschnitten 24a, 24b zu durchtrennen. Andernfalls wird das Brückenteil 35 abgetrennt bzw. entfernt, um das Kabel 21 zwischen den Bodenabschnitten 24a, 24b hindurch führen zu können.Then it becomes like Figure 10 can be seen, the cable 21 passed through the insertion frame 22. If the cable 21 does not have an end part that is larger than the inner passage width of the plug-in frame 22, it is not necessary to cut the bridge element 35 between the bottom sections 24a, 24b. Otherwise, the bridge part 35 is separated or removed in order to be able to pass the cable 21 between the bottom sections 24a, 24b.

Anschließend wird, wie aus Figur 11 ersichtlich, die Kabelzugentlastungseinrichtung 37 am Kabel 21 festgeklemmt, wobei dies außerhalb der Sockelleiste 3 bzw. außerhalb des Möbels 1 erfolgen kann.Then it becomes like Figure 11 can be seen, the cable strain relief device 37 clamped to the cable 21, this can be done outside the baseboard 3 or outside the furniture 1.

Wie aus Figur 12 ersichtlich, kann nunmehr die Kabelzugentlastungseinrichtung 37 in den Einsteckrahmen 22 eingeführt und in diesem formschlüssig verankert werden. Das Einführen erfolgt dabei in einer relativ zum Einsteckrahmen 22 angehobenen Stellung der Kabelzugentlastungseinrichtung 37. Wird nachfolgend die Kabelzugentlastungseinrichtung 37 innerhalb des Einsteckrahmens 22 nach unten bewegt, wirken die Formschlussverbindungselemente der Kabelzugentlastungseinrichtung 37 mit den darauf abgestimmten Formschlussverbindungselementen des Einsteckrahmens 22 derart zusammen, dass eine Bewegung der Kabelzugentlastungseinrichtung 37 und damit des Kabels 21 in Längsrichtung des Kabeldurchgangsraums 36 blockiert ist.How from Figure 12 can be seen, the cable strain relief device 37 can now be inserted into the plug-in frame 22 and anchored in this in a form-fitting manner. The insertion takes place in a raised position of the cable strain relief device 37 relative to the plug-in frame 22. If the cable strain relief device 37 is subsequently moved downward within the plug-in frame 22, the form-fitting connection elements of the cable strain-relief device 37 interact with the form-fitting connection elements of the plug-in frame 22 which are matched thereto such that a movement of the Cable strain relief device 37 and thus the cable 21 is blocked in the longitudinal direction of the cable passage space 36.

Die formschlüssige Verriegelungseinrichtung zwischen Kabelzugentlastungseinrichtung 37 und Einsteckrahmen 22 kann auch auf andere Weise realisiert werden. Beispielweise ist es möglich, die Kabelzugentlastungseinrichtung 37 als Drehkörper mit äußeren Verriegelungszapfen auszubilden, die in einer ersten Drehstellung in den Einsteckrahmen 22 eingeführt werden können und nach einem Drehen der Kabelzugentlastungseinrichtung 37 in eine Nut eingreifen, die in einer Umfangswand des Einsteckrahmens 22 angeordnet ist. Weiterhin können die Stege 45 auch an der Kabelzugentlastungseinrichtung 37 und die Führungsnuten 48 am Einsteckrahmen 22 angeordnet sein.The interlocking locking device between cable strain relief device 37 and plug-in frame 22 can also be implemented in another way. For example, it is possible to design the cable strain relief device 37 as a rotating body with outer locking pins that can be inserted into the plug-in frame 22 in a first rotational position and, after turning the cable strain relief device 37, engage in a groove that is arranged in a peripheral wall of the plug-in frame 22. Furthermore, the webs 45 can also be arranged on the cable strain relief device 37 and the guide grooves 48 on the plug-in frame 22.
