  • the invention makes use of surface elements which are produced entirely as a predominantly smooth-surfaced molded nonwoven made of plastic or from the fiber composite material described.
  • the term predominantly smooth-surfaced expresses that the molded fleece made of the fiber composite material has an overall rugged surface due to its binder-free production from the plastic fibers, despite its plate-like character. Because dispensing with a binding agent to connect the individual plastic fibers with one another means that the plastic fibers are only connected to one another at intersections and contact points.
  • polyester fibers are used as plastic fibers, which are first wetted with a plasticizer solution and then glued to one another at an elevated temperature, i.e. thermally bonded to one another without any binder. Temperatures in the range of approx. 80 ° C can be used here up to 160 ° C. At such temperatures, the melting point of the plastic fibers used is generally reached or slightly exceeded, so that in a subsequent pressing process, taking into account the specified elevated temperature, the individual plastic fibers are connected to one another at their intersection and contact points according to the invention without any additional binding agent.

This is because the surface element in question has sufficient rigidity and structural stability to be able to accommodate the display device, the memo board, etc. in a hanging manner or to be able to function as a hanging device. Due to the generally larger area of the surface element facing away from the furniture compared to the surface element facing the furniture, this surface element facing away from the furniture mainly takes on the function of soundproofing and acts as a privacy screen. In addition, due to the larger surface area of the surface element facing away from the furniture, there is the further possibility that the surface element facing away from the furniture has an overall spatial expansion.

Description

Die Erfindung betrifft eine Möbelansatzwand, insbesondere Tischmöbelansatzwand, mit einem Rahmen, und mit beidseitig des Rahmens angeordneten Flächenelementen, wobei zumindest ein Flächenelement ganz oder teilweise als überwiegend glattflächiges Formvlies aus Kunststoff ausgebildet ist, und wobei das Formvlies aus einem Faserverbundwerkstoff aus Kunststofffasern hergestellt ist, die mechanisch und/oder chemisch und/oder thermisch sowie bindemittelfrei miteinander verbunden sind.The invention relates to a furniture attachment wall, in particular a table furniture attachment wall, with a frame and with surface elements arranged on both sides of the frame, with at least one surface element being designed entirely or partially as a predominantly smooth-surfaced molded nonwoven made of plastic, and the molded nonwoven made of a fiber composite material made of plastic fibers, which are connected to one another mechanically and / or chemically and / or thermally and without binding agents.

Möbelansatzwände bezeichnen in der Regel Wände, die entweder wahlweise nachträglich oder von vornherein an Möbeln angebracht werden. Dabei überragt die betreffende Möbelansatzwand typischerweise das hiermit ausgerüstete Möbel. Auf diese Weise kann das mit der Möbelansatzwand ausgerüstete Möbel beispielsweise eine Raumteilerfunktion übernehmen. Sofern ein oder mehrere Tischmöbel mit der zugehörigen Möbelansatzwand ausgerüstet werden, besteht darüber hinaus die Möglichkeit, jeweils eigene Arbeitsplatzbereiche räumlich und akustisch voneinander zu trennen.Furniture attachment walls usually refer to walls that are either attached to furniture either retrospectively or from the outset. The relevant furniture attachment wall typically protrudes beyond the furniture equipped with it. In this way, the furniture equipped with the furniture attachment wall can, for example, take on a room divider function. If one or more table furniture is equipped with the associated furniture attachment wall, there is also the possibility of spatially and acoustically separating individual workstation areas from one another.

Denn die Möbelansatzwand übernimmt typischerweise neben einer optischen Trennfunktion zusätzlich eine Akustikfunktion bzw. dient zur Verbesserung der Raumakustik. Das lässt sich im Kern darauf zurückführen, dass das zumindest eine Flächenelement ganz oder teilweise als überwiegend glattflächiges Formvlies aus Kunststoff ausgebildet ist. Das heißt, trotz der überwiegend glattflächigen Auslegung des Formvlieses und seiner flächigen Ausdehnung zur Realisierung des jeweiligen Flächenelementes sorgt die unstrukturierte und letztlich raue Oberfläche eines solchen Formvlieses dafür, dass auftreffende Schallwellen absorbiert werden. Auch etwaige Schallreflektionen werden größtenteils unterdrückt.This is because the furniture attachment wall typically takes on an acoustic function in addition to an optical partition function or serves to improve the room acoustics. Essentially, this can be attributed to the fact that the at least one surface element is entirely or partially designed as a predominantly smooth-surfaced molded nonwoven made of plastic. In other words, despite the predominantly smooth-surfaced design of the molded fleece and its two-dimensional expansion for realizing the respective surface element, the unstructured and ultimately rough surface of such a molded fleece ensures that sound waves are absorbed. Any sound reflections are also largely suppressed.

Eine Möbelansatzwand des eingangs beschriebenen Aufbaues wird in der EP 3 165 348 A1 beschrieben. An dieser Stelle kommen Flächenelemente zum Einsatz, die beidseitig eines Rahmens angebracht werden. Aus Gründen einer kostengünstigen Herstellung sind die beiden Flächenelemente mit identischer Größe ausgerüstet.A furniture attachment wall of the structure described above is in the EP 3 165 348 A1 described. At this point, surface elements are used that are attached to both sides of a frame. For reasons of cost-effective production, the two surface elements are equipped with an identical size.

Bei der WO 2008/041872 A1 geht es um eine Wand, um einen Innenraum aufteilen zu können. Zu diesem Zweck sind erneut beidseitig eines Rahmens angebrachte Flächenelemente realisiert, bei denen es sich um jeweils ein Formvlies aus Kunststoff handelt.In the WO 2008/041872 A1 it is about a wall in order to be able to divide an interior space. For this purpose, surface elements attached to both sides of a frame are again implemented, each of which is a molded nonwoven made of plastic.

Ähnlich geht schließlich die US 2003/0070377 A1 vor, die eine zusammenlegbare Möbelansatzwand beschreibt. Auch in diesem Fall wird mit gleich großen Flächenelementen beidseitig eines mittigen Rahmens gearbeitet.Finally, it works similarly US 2003/0070377 A1 that describes a collapsible furniture attachment wall. In this case too, surface elements of the same size are used on both sides of a central frame.

Eine andere Möbelansatzwand wird beispielsweise in der DE 20 2012 012 556 U1 beschrieben. Hier geht es um ein textiles Akustik-Paneel in Sandwichbauweise, welches auch als sogenanntes Tischpaneel eingesetzt werden kann. Hierbei handelt es sich um eine Tischmöbelansatzwand, das heißt eine Ansatzwand für ein Tischmöbel, beispielsweise einen Bürotisch.Another furniture attachment wall is, for example, in the DE 20 2012 012 556 U1 described. This is about a textile acoustic panel in sandwich construction, which can also be used as a so-called table panel. This is a table furniture attachment wall, that is, an attachment wall for table furniture, for example an office table.

Das bekannte textile Akustikpaneel in Sandwichbauweise nach der DE 20 2012 012 556 U1 verfügt über eine Schalenkonstruktion, die einen mittigen Funktionsrahmen aufweist und unter anderem mit zwei beidseitigen Akustikvliesen ausgerüstet ist. Als Akustikvlies werden unter anderem solche mit einer Stärke von 1 mm bis 200 mm beschrieben, die unter anderem aus inhomogen in seinem Aufbau verdichteten Polyester hergestellt sind. Darüber hinaus können auch sonstige Dämm- und Akustikmaterialien wie Schäume oder Mineralfasern sowie Holzwollplatten zum Einsatz kommen.The well-known textile acoustic panel in sandwich construction according to the DE 20 2012 012 556 U1 has a shell construction that has a central functional frame and is equipped with two acoustic fleeces on both sides. As acoustic fleece, among other things, those with a thickness of 1 mm to 200 mm are described, which are made, among other things, of inhomogeneously compressed polyester. Furthermore Other insulation and acoustic materials such as foams or mineral fibers as well as wood wool panels can also be used.

Der Stand der Technik hat sich grundsätzlich bewährt. Allerdings sind Verbesserungen dergestalt möglich, dass insgesamt die Schallabsorption der beidseitig des Rahmens angeordneten Flächenelemente verbessert wird. Außerdem sind die bekannten Flächenelemente durch ihren mehrschichtigen Aufbau oftmals massiv ausgelegt und folglich für etwaige Nachrüstlösungen kaum geeignet. Hinzu kommt, dass massiv aufgebaute Akustik-Paneele entsprechend der DE 20 2012 012 556 U1 besonders robuste Befestigungen an beispielsweise Tischmöbeln erfordern. Das führt insgesamt zu einem erhöhten Gewicht des betreffenden Tischmöbels.The state of the art has basically proven itself. However, improvements are possible such that overall the sound absorption of the surface elements arranged on both sides of the frame is improved. In addition, the known surface elements are often designed to be massive due to their multi-layer structure and are consequently hardly suitable for any retrofitting solutions. In addition, the massive acoustic panels correspond to the DE 20 2012 012 556 U1 require particularly robust fastenings on, for example, table furniture. Overall, this leads to an increased weight of the table furniture in question.

Heutzutage wird insbesondere in modernen Großraumbüros jedoch eine gesteigerte Variabilität hinsichtlich der jeweils definierten Büroarbeitsplätze gefordert. Dabei sorgen mit entsprechenden Tischmöbelansatzwänden ausgerüstete Bürotische bzw. Tischmöbel generell bereits für eine akustische und optische Trennung einzelner Arbeitsplatzbereiche. Allerdings wird heutzutage eine besondere Flexibilität gefordert, wenn es beispielsweise darum geht, neue Teams oder Projektgruppen zusammenzustellen. Das setzt oftmals ein Umstellen und eine Neustrukturierung innerhalb des Großraumbüros voraus. Die bisherigen massiven Möbelansatzwände sind diesen Anforderungen nicht gewachsen bzw. erschweren eine Neuorientierung. Hier will die Erfindung insgesamt Abhilfe schaffen.Nowadays, however, especially in modern open-plan offices, increased variability is required with regard to the defined office workplaces. Office tables or table furniture equipped with appropriate table furniture attachment walls generally already provide acoustic and visual separation of individual workstation areas. However, nowadays special flexibility is required, for example when it comes to putting together new teams or project groups. This often requires moving and restructuring within the open-plan office. The previous massive furniture attachment walls are not up to these requirements or make reorientation more difficult. The invention aims to provide a remedy here overall.

Der Erfindung liegt das technische Problem zugrunde, eine derartige Möbelansatzwand und insbesondere Tischmöbelansatzwand so weiterzuentwickeln, dass bei gesteigerter akustischer Dämpfung zugleich das Gewicht des mit der betreffenden Möbelansatzwand ausgerüsteten Möbels nicht signifikant gegenüber dem Möbel ohne Ansatzwand ansteigt, so dass insgesamt eine flexible Aufstellung im Raum einfach und problemlos möglich ist.The invention is based on the technical problem of further developing such a furniture attachment wall, and in particular a table furniture attachment wall, in such a way that, with increased acoustic damping, the weight of the piece of furniture equipped with the relevant furniture attachment wall is not significant increases compared to the furniture without an extension wall, so that overall flexible installation in the room is easy and problem-free.

Zur Lösung dieser technischen Problemstellung ist eine gattungsgemäße Möbelansatzwand und insbesondere Tischmöbelansatzwand im Rahmen der Erfindung dadurch gekennzeichnet, dass ein möbelzugewandtes Flächenelement eine geringere Flächenausdehnung als ein möbelabgewandetes Flächenelement aufweist.To solve this technical problem, a generic furniture attachment wall and in particular table furniture attachment wall is characterized within the scope of the invention in that a surface element facing furniture has a smaller surface area than a surface element facing away from furniture.

Üblicherweise verfügt das erfindungsgemäß eingesetzte Formvlies bzw. das auf diese Weise realisierte Flächenelement über ein spezifisches Gewicht von weniger als 0,6 g/cm3. In Verbindung mit einem darüber hinaus und vorteilhaft als Hohlprofilrahmen ausgebildeten Rahmen wird hierdurch insgesamt das Gewicht bisheriger Ausführungsformen solcher Möbelansatzwände deutlich unterschritten. Tatsächlich lassen sich im Rahmen der Erfindung Möbelansatzwände realisieren, die je nach ihrer flächenmäßigen Ausdehnung ein Gewicht von lediglich bis zu 5 kg aufweisen, dementsprechend das Gewicht eines Tischmöbels nicht signifikant erhöhen. Das gilt erst recht für den Fall, dass der Rahmen vorteilhaft aus einem Leichtmetall, beispielsweise Aluminium, hergestellt ist. Generell kann auch ein Rahmen aus Kunststoff zum Einsatz kommen. Das gesamte geringe Gewicht stellt sich besonders für den Fall ein, dass beide Flächenelemente jeweils als Formvlies mit den geschilderten Eigenschaften ausgebildet sind. Generell kann aber auch nur ein Flächenelement als Formvlies und das andere Flächenelement als beispielsweise Platte aus Kunststoff, Holz, Metall sowie Mischformen hergestellt sein.The molded fleece used according to the invention or the surface element realized in this way usually has a specific weight of less than 0.6 g / cm 3 . In conjunction with a frame that is also advantageously designed as a hollow profile frame, the overall weight of previous embodiments of such furniture attachment walls is significantly below the total. In fact, within the scope of the invention, furniture attachment walls can be realized which, depending on their areal extension, have a weight of only up to 5 kg, and accordingly do not significantly increase the weight of table furniture. This is especially true in the event that the frame is advantageously made from a light metal, for example aluminum. In general, a frame made of plastic can also be used. The overall low weight occurs especially in the event that both surface elements are each designed as a molded fleece with the properties described. In general, however, only one surface element can be produced as a molded fleece and the other surface element as, for example, a plate made of plastic, wood, metal and mixed forms.

Darüber hinaus mag das jeweilige Flächenelement neben dem glattflächigen Formvlies zusätzlich noch mit einer Beschichtung bzw. Kaschierung ausgerüstet sein. Hierbei kann es sich ebenfalls um ein textiles Flächenmaterial, beispielsweise aus einem Filz oder Vlies handeln. Selbst eine Kunststofffolie ist denkbar. Auch Farbkaschierungen in unterschiedlichen Farben werden von der Erfindung umfasst.In addition, the respective surface element may also be equipped with a coating or lamination in addition to the smooth-surfaced molded fleece his. This can also be a flat textile material, for example made of felt or fleece. Even a plastic film is conceivable. Color laminations in different colors are also covered by the invention.

Im Regelfall greift die Erfindung jedoch auf Flächenelemente zurück, die ganz als überwiegend glattflächiges Formvlies aus Kunststoff bzw. aus dem beschriebenen Faserverbundwerkstoff hergestellt sind. Der Begriff überwiegend glattflächig drückt dabei aus, dass das Formvlies aus dem Faserverbundwerkstoff aufgrund seiner bindemittelfreien Herstellung aus den Kunststofffasern trotz des plattenförmigen Charakters über eine insgesamt zerklüftet ausgebildete Oberfläche verfügt. Denn der Verzicht auf ein Bindemittel zur Verbindung der einzelnen Kunststofffasern untereinander führt dazu, dass die Kunststofffasern lediglich an Kreuzungs- und Berührstellen miteinander verbunden sind.As a rule, however, the invention makes use of surface elements which are produced entirely as a predominantly smooth-surfaced molded nonwoven made of plastic or from the fiber composite material described. The term predominantly smooth-surfaced expresses that the molded fleece made of the fiber composite material has an overall rugged surface due to its binder-free production from the plastic fibers, despite its plate-like character. Because dispensing with a binding agent to connect the individual plastic fibers with one another means that the plastic fibers are only connected to one another at intersections and contact points.

Durch die bindemittelfreie Kopplung der Kunststofffasern in den Berührstellen untereinander wird insgesamt ein räumliches Netzwerk aus den Kunststofffasern mit dazwischen verbleibenden Freiräumen in chaotischer Anordnung gebildet. Diese stellt eine optimale Oberfläche zur Absorption von auftreffendem Schall dar, und zwar auch und insbesondere dann, wenn das Formvlies überwiegend glattflächig ausgebildet ist. Zusätzliche Maßnahmen zur Erhöhung der Schalldämmung wie beispielsweise Sicken oder eine räumliche Strukturierung des glattflächigen Formvlieses sind entbehrlich.As a result of the binder-free coupling of the plastic fibers in the contact points with one another, a spatial network of the plastic fibers with the remaining free spaces in between is formed in a chaotic arrangement. This represents an optimal surface for the absorption of incident sound, namely also and especially when the molded fleece is predominantly smooth-surfaced. Additional measures to increase the sound insulation, such as beading or a spatial structuring of the smooth-surfaced molded fleece, are unnecessary.

Im Regelfall kommen als Kunststofffasern Polyesterfasern zum Einsatz, die zunächst mit einer Weichmacherlösung benetzt und dann bei einer erhöhten Temperatur miteinander verklebt werden, also bindemittelfrei thermisch miteinander verbunden werden. Hierbei kann mit Temperaturen im Bereich von ca. 80 °C bis 160 °C gearbeitet werden. Bei solchen Temperaturen wird im Allgemeinen der Schmelzpunkt der eingesetzten Kunststofffasern erreicht oder geringfügig überschritten, so dass bei einem anschließenden Pressvorgang unter Berücksichtigung der angegebenen erhöhten Temperatur die einzelnen Kunststofffasern ohne zusätzlich eingebrachtes Bindemittel an ihren Kreuzungs- und Berührstellen erfindungsgemäß miteinander verbunden werden. Eine solche Vorgehensweise ist grundsätzlich durch die DE 1 237 057 A oder auch die DE 1 469 347 A bekannt.As a rule, polyester fibers are used as plastic fibers, which are first wetted with a plasticizer solution and then glued to one another at an elevated temperature, i.e. thermally bonded to one another without any binder. Temperatures in the range of approx. 80 ° C can be used here up to 160 ° C. At such temperatures, the melting point of the plastic fibers used is generally reached or slightly exceeded, so that in a subsequent pressing process, taking into account the specified elevated temperature, the individual plastic fibers are connected to one another at their intersection and contact points according to the invention without any additional binding agent. Such a procedure is basically by the DE 1 237 057 A or also the DE 1 469 347 A known.

Darüber hinaus lassen sich die vorteilhaft eingesetzten Polyester- bzw. PET-Fasern nicht nur brandhemmend ausrüsten, sondern können auch jede beliebige Farbe annehmen bzw. mit einer solchen Farbe eingefärbt und zur Verfügung gestellt werden. Ferner neigen Polyesterfasern praktisch nicht zu einer elektrostatischen Aufladung und sind folglich für den Einsatzzweck bei der Ausrüstung von beispielsweise Großraumbüros prädestiniert. Hinzu kommt, dass Kunststoff und insbesondere Polyesterfasern im Vergleich zu Naturfasern nicht nur übliche Brandprüfungen nach DIN EN 1021 Teil 1 und 2 bestehen, sondern aufgrund ihrer robusten Gestaltung und des dauerhaften Charakters mit Lebensdauern von mehreren Jahrzehnten ausgerüstet sind.In addition, the polyester or PET fibers that are advantageously used can not only be given a fire-retardant finish, but can also take on any color or be colored with such a color and made available. Furthermore, polyester fibers have practically no tendency to electrostatic charging and are therefore predestined for use in equipping open-plan offices, for example. In addition, compared to natural fibers, plastic and polyester fibers in particular not only pass the usual fire tests according to DIN EN 1021 Part 1 and 2, but are also equipped with a service life of several decades due to their robust design and durable character.

Das hat insgesamt zur Folge, dass die auf diese Weise hergestellten Formvliese im an dieser Stelle relevanten Frequenzbereich von 100 Hz bis 5000 Hz einen Schallabsorptionsgrad von wenigstens 0,5 erreichen. Bei einem Schallabsorptionsgrad von 0,5 werden wenigstens 50 % der auftreffenden Schallenergie absorbiert und im Maximum 50 % der Schallenergie reflektiert. Das gilt im angegebenen Frequenzbereich von 100 Hz bis 5000 Hz, der nahezu ausschließlich in Büroräumen und insbesondere Großraumbüros beobachtet wird. Das Flächenelement bzw. das an dieser Stelle eingesetzte glattflächige Formvlies verfügt hierzu über eine Materialstärke, die im Regelfall bis zu ca. 50 mm betragen kann. Im Allgemeinen liegt die Materialstärke im Bereich zwischen 5 mm bis 20 mm für das Formvlies. Weitere Einzelheiten und strukturelle Auslegungen solcher Formvliese werden in der EP 3 241 462 A1 beschrieben, die ein entsprechend aufgebautes Möbel- und/oder Raumteilerstrukturelement zum Gegenstand hat.The overall consequence of this is that the molded nonwovens produced in this way achieve a sound absorption coefficient of at least 0.5 in the frequency range of 100 Hz to 5000 Hz relevant at this point. With a sound absorption coefficient of 0.5, at least 50% of the sound energy is absorbed and a maximum of 50% of the sound energy is reflected. This applies in the specified frequency range of 100 Hz to 5000 Hz, which is observed almost exclusively in offices and especially open-plan offices. The surface element or the smooth-surfaced molded fleece used at this point has a material thickness that is generally up to approx. 50 can be mm. In general, the material thickness is in the range between 5 mm and 20 mm for the molded fleece. Further details and structural designs of such molded webs are given in EP 3 241 462 A1 described, which has a correspondingly constructed furniture and / or room divider structural element as its subject.

Bei der Realisierung der erfindungsgemäßen Möbelansatzwand wird im Allgemeinen so vorgegangen, dass zumindest ein Flächenelement den Rahmen flächenmäßig überragt. Im Allgemeinen überragen beide Flächenelemente den Rahmen flächenmäßig. Dadurch ist die Möbelansatzwand insgesamt sandwichartig aufgebaut, und zwar mit dem mittigen Rahmen und den beiden den Rahmen jeweils flächenmäßig überragenden beidseitigen Flächenelementen regelmäßig aus dem speziellen und beschriebenen Formvlies. Dadurch trifft Schall immer auf das Flächenelement aus dem überwiegend glattflächigen Formvlies und wird die gewünschte Schallabsorption beobachtet. Das gilt sowohl für das möbelzugewandte Flächenelement als auch das möbelabgewandte Flächenelement.When implementing the furniture attachment wall according to the invention, the procedure is generally such that at least one surface element projects over the frame in terms of area. In general, both surface elements project beyond the frame in terms of area. As a result, the furniture attachment wall is constructed in a sandwich-like manner overall, with the central frame and the two surface elements on both sides protruding over the frame, regularly made of the special and described molded fleece. As a result, sound always hits the surface element made of the predominantly smooth-surfaced molded fleece and the desired sound absorption is observed. This applies to both the surface element facing the furniture and the surface element facing away from the furniture.

Erfindungsgemäß verfügen die beiden Flächenelemente über eine unterschiedliche Größe. So weist das möbelzugewandte Flächenelement eine geringere Flächenausdehnung als das möbelabgewandte Flächenelement auf. Auf diese Weise kann das möbelzugewandte Flächenelement mit der geringeren Flächenausdehnung beispielsweise als Hängevorrichtung genutzt werden (selbstverständlich neben seiner originären Funktion zur Schalldämmung). An dem betreffenden möbelzugewandten Flächenelement lässt sich beispielsweise ein sogenanntes Memoboard, eine Notiztafel etc. durch einfaches Anhängen befestigen und liegt aufgrund der geringeren Flächenausdehnung des möbelzugewandten Flächenelementes im Vergleich zum möbelabgewandten Flächenelement unmittelbar im Blickfeld eines am Tischmöbel sitzenden Bedieners. Alternativ oder zusätzlich kann das möbelzugewandte Flächenelement auch zur Anbringung einer Anzeigevorrichtung genutzt werden. Mit Hilfe der Anzeigevorrichtung lässt sich in der Art einer Ampel die Belegung oder Nichtbelegung des betreffenden Tischmöbels sichtbar anzeigen.According to the invention, the two surface elements have a different size. The surface element facing the furniture thus has a smaller surface area than the surface element facing away from the furniture. In this way, the surface element facing the furniture with the smaller surface area can be used, for example, as a hanging device (of course in addition to its original function for soundproofing). For example, a so-called memo board, a notice board, etc. can be attached to the relevant furniture-facing surface element by simply attaching it and, due to the smaller surface area of the furniture-facing surface element compared to the furniture-facing surface element, is directly in the field of vision of an Seated operator's table furniture. Alternatively or additionally, the surface element facing the furniture can also be used to attach a display device. With the aid of the display device, the occupancy or non-occupancy of the table furniture in question can be visibly displayed in the manner of a traffic light.

Das alles gelingt problemlos dadurch, dass das betreffende Flächenelement ganz oder teilweise als überwiegend glattflächiges Formvlies aus Kunststoff ausgebildet ist und aus einem Faserverbundwerkstoff aus Kunststofffasern hergestellt wird. Denn dadurch verfügt das betreffende Flächenelement über eine ausreichende Steifigkeit und Strukturstabilität, um die Anzeigevorrichtung, das Memoboard etc. hängend aufnehmen zu können bzw. als Hängevorrichtung fungieren zu können. Aufgrund der im Allgemeinen größeren Fläche des möbelabgewandten Flächenelementes gegenüber dem möbelzugewandten Flächenelement übernimmt dieses möbelabgewandte Flächenelement hauptsächlich die Funktion der Schalldämmung und fungiert als Sichtschutz. Außerdem besteht aufgrund der größeren Flächenausdehnung des möbelabgewandten Flächenelementes die weitergehende Möglichkeit, dass das möbelabgewandte Flächenelement insgesamt eine räumliche Ausdehnung aufweist. In diesem Fall kann das möbelabgewandte Flächenelement nicht nur beidseitig des Rahmens verlängert sein, sondern auch gegenüber einer durch den Rahmen vorgegebenen Ebene ein- oder beidseitig abgeknickt werden. Dadurch lässt sich beispielsweise ein mit der erfindungsgemäßen Möbelansatzwand ausgerüsteter Tisch oder Bürotisch nahezu vollständig einhausen. Damit wird eine besonders wirksame akustische Abschirmung erreicht.All of this succeeds without any problems in that the surface element in question is designed entirely or partially as a predominantly smooth-surfaced molded nonwoven made of plastic and is made of a fiber composite material made of plastic fibers. This is because the surface element in question has sufficient rigidity and structural stability to be able to accommodate the display device, the memo board, etc. in a hanging manner or to be able to function as a hanging device. Due to the generally larger area of the surface element facing away from the furniture compared to the surface element facing the furniture, this surface element facing away from the furniture mainly takes on the function of soundproofing and acts as a privacy screen. In addition, due to the larger surface area of the surface element facing away from the furniture, there is the further possibility that the surface element facing away from the furniture has an overall spatial expansion. In this case, the surface element facing away from the furniture can not only be extended on both sides of the frame, but can also be bent on one or both sides with respect to a plane predetermined by the frame. In this way, for example, a table or office table equipped with the furniture attachment wall according to the invention can be almost completely enclosed. A particularly effective acoustic shielding is thus achieved.

Beide Flächenelemente verfügen im Allgemeinen über eine überwiegend gleiche Materialstärke. Diese kann im Bereich von 5 mm bis 20 mm liegen, wie dies zuvor bereits beschrieben wurde. Beispielsweise ist es denkbar, dass sowohl das möbelzugewandte Flächenelement als auch das möbelabgewandte Flächenelement jeweils eine Materialstärke von ca. 10 mm aufweisen. Selbstverständlich kann auch mit unterschiedlichen Materialstärken gearbeitet werden. Im Allgemeinen reicht die zuvor angegebene Materialstärke jedoch aus, um die gewünschte Schallabsorption und insbesondere den zuvor bereits beschriebenen Schallabsorptionsgrad von wenigstens 0,5 im relevanten Frequenzbereich von 100 Hz bis 5000 Hz zu erreichen.Both surface elements generally have predominantly the same material thickness. This can range from 5 mm to 20 mm, such as this has already been described above. For example, it is conceivable that both the surface element facing the furniture and the surface element facing away from the furniture each have a material thickness of approximately 10 mm. Of course, different material thicknesses can also be used. In general, however, the material thickness specified above is sufficient to achieve the desired sound absorption and in particular the degree of sound absorption already described of at least 0.5 in the relevant frequency range from 100 Hz to 5000 Hz.

Zur Befestigung der Möbelansatzwand an dem hiermit ausgerüsteten Möbel verfügt der Rahmen in der Regel über wenigstens zwei Winkel. Die beiden Winkel werden dabei vorteilhat an jeweils Schmalseiten des rechteckförmigen Rahmens angeschlossen. Außerdem hat sich in diesem Zusammenhang bewährt, wenn die erfindungsgemäße Möbelansatzwand zusätzlich mit einer Kabelwanne ausgerüstet ist. Die Kabelwanne ist dabei üblicherweise nach oben bzw. in Richtung auf beispielsweise eine Tischplatte eines mit der Möbelansatzwand ausgerüsteten Bürotisches hin geöffnet. Dadurch können in der Kabelwanne Kabel wie beispielsweise Netzkabel, Verbindungskabel zwischen Computer und Bildschirm etc. aufgenommen und geführt werden.To attach the furniture attachment wall to the furniture equipped with it, the frame generally has at least two angles. The two angles are advantageously connected to each narrow side of the rectangular frame. In addition, it has proven itself in this context if the furniture attachment wall according to the invention is additionally equipped with a cable trough. The cable trough is usually open upwards or in the direction of, for example, a tabletop of an office table equipped with the furniture attachment wall. As a result, cables such as power cables, connecting cables between computer and screen, etc. can be accommodated and routed in the cable trough.

Da ferner der Rahmen vorteilhaft als Hohlprofilrahmen ausgebildet ist und darüber hinaus aus einem Leichtmetall, beispielsweise Aluminium, oder aus Kunststoff hergestellt ist, kann der Rahmen für Zusatzfunktionen genutzt werden. Hier hat es sich als besonders günstig erwiesen, wenn im Innern des Rahmens elektrische Zuleitungen für Anschlussbuchsen, elektrische Geräte, Leuchten etc. aufgenommen werden. Auch die elektrische Zuleitung für die zuvor bereits angesprochene und an das möbelzugewandte Flächenelement angeschlossene Anzeigevorrichtung lässt sich im Innern des Hohlprofilrahmens führen. Beispielsweise mag der Rahmen bzw. Hohlprofilrahmen in seinem Innern Zuleitungen für USB-Anschlüsse aufnehmen. Auf diese Weise können beispielsweise seitlich des Rahmens bzw. Hohlprofilrahmens ein oder mehrere US-Anschlüsse je nach Bedarf angebracht werden. Ferner ist über den Rahmen beispielsweise die elektrische Versorgung einer Leuchte und insbesondere Arbeitsplatzleuchte möglich, die zu diesem Zweck in eine zugehörige Anschlussbuchse im Rahmen eingesteckt werden mag.Since the frame is also advantageously designed as a hollow profile frame and is also made from a light metal, for example aluminum, or from plastic, the frame can be used for additional functions. It has proven to be particularly advantageous here if electrical supply lines for connection sockets, electrical devices, lights, etc. are accommodated in the interior of the frame. The electrical supply line for the display device already mentioned and connected to the surface element facing the furniture can also be routed inside the hollow profile frame. For example, the frame or hollow profile frame may in his Inside feed lines for USB connections. In this way, one or more US connections can be attached to the side of the frame or hollow profile frame as required. Furthermore, for example, the electrical supply of a lamp and in particular a workplace lamp is possible via the frame, which for this purpose may be plugged into an associated connection socket in the frame.

Die jeweiligen Anschlussbuchsen sind dabei jeweils in Seitenflächen des meistens rechteckförmigen Rahmens bzw. Hohlprofilrahmens vorgesehen, die von den am Rahmen angebrachten Flächenelementen frei sind. Meistens erstrecken sich die betreffenden Seitenflächen des Rahmens entlang eines durch den Rahmen vorgegebenen Spaltes zwischen dem möbelzugewandten Flächenelement und dem möbelabgewandten Flächenelement, die jeweils beidseitig an den Rahmen angeschlossen sind.The respective connection sockets are each provided in side surfaces of the mostly rectangular frame or hollow profile frame, which are free of the surface elements attached to the frame. Most of the time, the relevant side surfaces of the frame extend along a gap predetermined by the frame between the surface element facing the furniture and the surface element facing away from the furniture, each of which is connected to the frame on both sides.

Auf diese Weise übernimmt der Rahmen bzw. Hohlprofilrahmen eine Zusatzfunktion dergestalt, dass er nicht nur zur Anbringung und Halterung der Flächenelemente genutzt wird, sondern auch als gleichsam Anschlussverteiler für elektrische Geräte dient. Dabei wird man aus Sicherheitsgründen typischerweise mit Niedervolt-Zuleitungen im Innern des Hohlprofilrahmens arbeiten, wie Sie beispielsweise in Computernetzwerken oder zur elektrischen Versorgung von Niedervolt-Leuchten eingesetzt werden. Der Rahmen kann darüber hinaus und seinerseits über eine Anschlussbuchse mit einem Rechnernetzwerk oder einer elektrischen Energieversorgung gekoppelt werden, die am Aufstellungsort des zugehörigen Tischmöbels in der Regel vorhanden ist.In this way, the frame or hollow profile frame assumes an additional function in such a way that it is not only used to attach and hold the surface elements, but also serves as a connection distributor for electrical devices. For safety reasons, you will typically work with low-voltage supply lines inside the hollow profile frame, such as those used in computer networks or for the electrical supply of low-voltage lights. The frame can also be coupled via a connection socket to a computer network or to an electrical power supply that is usually present at the installation site of the associated table furniture.

Vorteilhaft ist die Kabelwanne an eine untere Breitseite des rechteckförmigen Rahmens angeschlossen bzw. verläuft entlang der unteren Breitseite. Außerdem wird die Auslegung meistens so getroffen, dass die Kabelwanne unterhalb der beiden Winkel verläuft. Auf diese Weise bildet die Kabelwanne mit den darüber angeordneten beiden Winkeln einen nach oben hin offenen Kabelkanal. Die Kabelwanne kann schließlich über eine Breite verfügen, welche der Länge eines Überbrückungsschenkels des Winkels entspricht oder die Länge des fraglichen Überbrückungsschenkels überschreitet. Dadurch wird ein zwischen beispielsweise einer Tischplatte des mit der Möbelansatzwand ausgerüsteten Bürotisches und dem möbelzugewandten Flächenelement beobachteter Spalt verschlossen, nämlich mit Hilfe der Kabelwanne, die zu diesem Zweck von ihrer Länge her außerdem an die Längserstreckung der Tischplatte angepasst werden kann.The cable trough is advantageously connected to a lower broad side of the rectangular frame or runs along the lower broad side. In addition, the design is usually made so that the cable tray runs below the two angles. In this way, the cable trough with the two angles arranged above it forms a cable duct that is open at the top. The cable trough can finally have a width which corresponds to the length of a bridging leg of the angle or which exceeds the length of the bridging leg in question. As a result, a gap observed between, for example, a table top of the office table equipped with the furniture attachment wall and the surface element facing the furniture is closed, namely with the help of the cable trough, the length of which can also be adapted to the longitudinal extent of the table top for this purpose.

Im Ergebnis wird eine Möbelansatzwand zur Verfügung gestellt, die insbesondere für eine optische und akustische Trennung einzelner Arbeitsplatzbereiche sorgt. Dazu ist die Möbelansatzwand vorteilhaft als Tischmöbelansatzwand ausgelegt und an einen Bürotisch angeschlossen. Das gilt selbstverständlich nur beispielhaft. Der Anschluss der Möbelansatzwand bzw. Tischmöbelansatzwand an den Bürotisch kann dabei werkseitig und von vornherein erfolgen oder auch nachträglich und bedarfsweise.As a result, a furniture attachment wall is made available which, in particular, ensures visual and acoustic separation of individual workstation areas. For this purpose, the furniture attachment wall is advantageously designed as a table furniture attachment wall and is connected to an office table. Of course, this only applies as an example. The connection of the furniture attachment wall or table furniture attachment wall to the office table can be done at the factory and from the outset, or later and if necessary.

Durch die hohe akustische Dämpfung der erfindungsgemäßen Möbelansatzwand in Verbindung mit ihrem geringen Gewicht ist sie für flexible Lösungen und Anpassungen insbesondere in Großraumbüros prädestiniert. Hierin sind die wesentlichen Vorteile zu sehen.Due to the high acoustic damping of the furniture attachment wall according to the invention in connection with its low weight, it is predestined for flexible solutions and adjustments, especially in open-plan offices. This is where the main advantages can be seen.

Im Folgenden wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel darstellenden Zeichnung näher erläutert; es zeigen:

In the following the invention is explained in more detail with reference to a drawing showing only one embodiment; show it:
Fig. 1
a furniture attachment wall with associated table furniture in the form of an office table in perspective, partly in section or broken open and
Fig. 2
a schematic cross section through the object according to Fig. 1 .

In den Figuren ist eine Möbelansatzwand und konkret eine Tischmöbelansatzwand dargestellt. Das heißt, eine Wand, die im Ausführungsbeispiel an ein Tischmöbel und konkret einen Bürotisch 1, 2 angesetzt wird bzw. angesetzt werden kann. Der hiermit ausgerüstete Bürotisch 1, 2 verfügt im Detail über eine Tischplatte 1 und ein die Tischplatte 1 tragendes Gestell 2. Die nachfolgend noch näher zu beschreibende Möbelansatzwand bzw. Tischmöbelansatzwand ist dabei an eine hintere Längskante der Tischplatte 1 angesetzt bzw. in diesem Bereich mit dem Rahmen 2 verbunden, wie nachfolgend noch im Detail erläutert wird. Sofern die Tischplatte 1 höhenveränderbar gegenüber dem Rahmen 2 ausgelegt ist, lässt sich die Möbelansatzwand bzw. Tischmöbelansatzwand durch ihren Anschluss an die Tischplatte 1 bzw. einen darunter befindlichen Tischrahmen zusammen mit der Tischplatte 1 bewegen. Es ist aber auch möglich, dass die Möbelansatzwand bzw. Tischmöbelansatzwand generell ortsfest an den Rahmen 2 angeschlossen wird. Der Anschluss kann dabei dauerhaft oder lösbar ausgelegt sein.In the figures, a furniture attachment wall and specifically a table furniture attachment wall is shown. That is to say, a wall which, in the exemplary embodiment, is or can be attached to table furniture and specifically to an office table 1, 2. The office table 1, 2 equipped with this has in detail a table top 1 and a frame 2 carrying the table top 1. The furniture attachment wall or table furniture attachment wall to be described in more detail below is attached to a rear longitudinal edge of the table top 1 or in this area with the Frame 2 connected, as will be explained in detail below. If the table top 1 is designed to be height-adjustable with respect to the frame 2, the furniture attachment wall or table furniture attachment wall can be moved together with the table top 1 through its connection to the table top 1 or a table frame located below it. However, it is also possible that the furniture attachment wall or table furniture attachment wall is generally fixedly connected to the frame 2. The connection can be designed to be permanent or detachable.

Die Möbelansatzwand bzw. Tischmöbelansatzwand setzt sich nach dem Ausführungsbeispiel und ganz generell aus einem Rahmen 3 und beidseitig des Rahmens 3 angeordneten Flächenelementen 4, 5 zusammen. Bei den Flächenelementen 4, 5 handelt es sich einerseits um ein möbelzugewandtes Flächenelement 4 und andererseits ein möbelabgewandtes Flächenelement 5. Beide Flächenelemente 4, 5 nehmen den Rahmen 3 sandwichartig zwischen sich auf, wie dies anhand der Schnittdarstellung bzw. Seitenansicht in der Fig. 2 deutlich wird. Außerdem ist die Auslegung so getroffen, dass beide Flächenelemente 4, 5 den dazwischen befindlichen Rahmen 3 jeweils flächenmäßig überragen.According to the exemplary embodiment and quite generally, the furniture attachment wall or table furniture attachment wall is composed of a frame 3 and surface elements 4, 5 arranged on both sides of the frame 3. The surface elements 4, 5 are on the one hand a surface element 4 facing furniture and on the other hand a surface element 5 facing away from the furniture. Both surface elements 4, 5 sandwich the frame 3 between them, as shown on the basis of the sectional view or side view in FIG Fig. 2 becomes clear. In addition, the design is made in such a way that both surface elements 4, 5 each project over the area of the frame 3 located between them.

Das jeweilige Flächenelement 4, 5 ist ganz oder teilweise als überwiegend glattflächiges Formvlies aus Kunststoff ausgebildet. Es kann aber auch nur mit einem als glattflächiges Formvlies aus Kunststoff ausgebildeten Flächenelement 4 gearbeitet werden, während das andere Flächenelement 5 beispielsweise als Platte aus Holz, Kunststoff, Metall etc. ausgebildet ist. Das ist jedoch nicht dargestellt. Nach dem Ausführungsbeispiel setzt sich das jeweilige Flächenelement 4, 5 ganz bzw. vollständig aus dem überwiegend glattflächigen Formvlies aus Kunststoff zusammen bzw. ist aus diesem aufgebaut. Das Formvlies selbst ist dabei aus einem Faserverbundwerkstoff aus Kunststofffasern hergestellt. Die Kunststofffasern werden mechanisch und/oder chemisch und/oder thermisch sowie bindemittelfrei miteinander verbunden, wie dies in der Beschreibungseinleitung im Detail dargelegt wurde.The respective surface element 4, 5 is entirely or partially designed as a predominantly smooth-surfaced molded nonwoven made of plastic. However, it is also possible to work with only one surface element 4 designed as a smooth-surfaced molded fleece made of plastic, while the other surface element 5 is designed, for example, as a plate made of wood, plastic, metal, etc. However, this is not shown. According to the exemplary embodiment, the respective surface element 4, 5 is composed entirely or completely of the predominantly smooth-surfaced molded nonwoven made of plastic or is constructed from this. The molded fleece itself is made from a fiber composite material made of plastic fibers. The plastic fibers are connected to one another mechanically and / or chemically and / or thermally and without binding agents, as was explained in detail in the introduction to the description.

Als Kunststofffasern kommen im Beispielfall zur Herstellung des Formvlieses Polyester- bzw. PET-Fasern zum Einsatz, die eingefärbt werden können und im Übrigen brandschutzhemmend ausgelegt sind. Das gilt selbstverständlich nur beispielhaft. In der Fig. 1 ist angedeutet, dass das möbelzugewandte Flächenelement 4 eine geringere räumliche Ausdehnung als das möbelabgewandte Flächenelement 5 aufweist. Tatsächlich kann das möbelabgewandte Flächenelement 5 räumlich ausgedehnt sein, beispielsweise im Vergleich zu einer von dem Rahmen 3 vorgegebenen Flächenausdehnung mit einer Abkantung oder Abknickung ausgerüstet sein. Beide Flächenelemente 4, 5 verfügen überwiegend über eine gleiche Materialstärke, die nach dem Ausführungsbeispiel im Bereich von jeweils ca. 10 mm liegt.In the example, polyester or PET fibers, which can be colored and are also designed to be fire-retardant, are used as plastic fibers to produce the molded fleece. Of course, this only applies as an example. In the Fig. 1 it is indicated that the surface element 4 facing the furniture has a smaller spatial extent than the surface element 5 facing away from the furniture. In fact, the surface element 5 facing away from the furniture can be spatially extended, for example, in comparison to a surface extension predetermined by the frame 3, it can be equipped with a bevel or kink. Both surface elements 4, 5 predominantly have the same material thickness, which, according to the exemplary embodiment, is in the range of approximately 10 mm each.

Der Rahmen 3 ist als Hohlprofilrahmen ausgebildet. Im Ausführungsbeispiel ist der Rahmen 3 bzw. Hohlprofilrahmen aus einem Leichtmetall, vorliegend aus Aluminium hergestellt. Das jeweilige Flächenelement 4, 5 verfügt über ein spezifisches Gewicht von weniger als 0,6 g/cm3. Das führt in Verbindung mit dem als Hohlprofilrahmen aus Aluminium ausgebildeten Rahmen 3 insgesamt zu einem Gewicht der solchermaßen realisierten Tischmöbelansatzwand, welches beispielsweise und je nach Flächenausdehnung im Maximum 5 kg beträgt oder betragen kann. Dadurch steigt das Gesamtgewicht des im Ausführungsbeispiel mit der Tischmöbelansatzwand ausgerüsteten Bürotisches 1, 2 nach Anbau der Tischmöbelansatzwand nur geringfügig. Folgerichtig kann der Bürotisch 1, 2 mit der angebauten Tischmöbelansatzwand problemlos innerhalb eines Großraumbüros hin- und herbewegt werden.The frame 3 is designed as a hollow profile frame. In the exemplary embodiment, the frame 3 or hollow profile frame is made of a light metal, in the present case made of aluminum. The respective surface element 4, 5 has a specific weight of less than 0.6 g / cm 3 . In connection with the frame 3 designed as a hollow profile frame made of aluminum, this leads to a total weight of the table furniture attachment wall implemented in this way, which is or can be a maximum of 5 kg, for example and depending on the surface area. As a result, the total weight of the office table 1, 2 equipped with the table furniture attachment wall in the exemplary embodiment increases only slightly after the table furniture attachment wall has been attached. Consequently, the office table 1, 2 with the attached table furniture attachment wall can easily be moved back and forth within an open-plan office.

Zur Befestigung der Tischmöbelansatzwand an dem Bürotisch 1, 2 ist der Rahmen 3 mit wenigstens zwei Winkeln 6a, 6b ausgerüstet. Bei dem betreffenden Winkel 6a, 6b handelt es sich um einen L-förmigen Winkel oder Rechteckwinkel 6a, 6b, der mit einem Überbrückungsschenkel 6a und einem Befestigungsschenkel 6b ausgerüstet ist. Mit dem Befestigungsschenkel 6b wird der Winkel 6a, 6b im Ausführungsbeispiel an dem Rahmen 3 festgelegt. Der Überbrückungsschenkel 6a sorgt demgegenüber für eine beabstandete Anbringung der Möbelansatzwand bzw. Tischmöbelansatzwand an einem die Tischplatte 1 tragenden Tischrahmen 8, wie man in der Fig. 2 erkennt.To attach the table furniture attachment wall to the office table 1, 2, the frame 3 is equipped with at least two angles 6a, 6b. The angle 6a, 6b concerned is an L-shaped angle or rectangular angle 6a, 6b, which is equipped with a bridging leg 6a and a fastening leg 6b. In the exemplary embodiment, the angle 6a, 6b is fixed to the frame 3 with the fastening leg 6b. The bridging leg 6a, on the other hand, ensures that the furniture attachment wall or table furniture attachment wall is attached to a table frame 8 carrying the table top 1, as shown in FIG Fig. 2 recognizes.

Auf diese Weise stellt sich zwischen einer hinteren bzw. ansatzwandseitigen Längskante der Tischplatte 1 und dem möbelzugewandten Flächenelement 4 ein Spalt S ein, der im Rahmen des Ausführungsbeispiels mit einer zusätzlichen Kabelwanne 7 in Aufsicht verschlossen wird. Die Kabelwanne 7 ist zu diesem Zweck an eine untere Breitseite des rechteckförmigen Rahmens 3 bzw. an die beiden Schmalseiten angeschlossen, ebenso wie die beiden Winkel 6a, 6b. Außerdem ist die Auslegung so getroffen, dass die Kabelwanne 7 unterhalb der beiden Winkel 6a, 6b verläuft. Die Kabelwanne 7 verfügt dabei insgesamt über eine Breite, welche der Länge des Überbrückungsschenkels 6a des Winkels 6a, 6b entspricht oder diese überschreitet, wie man anhand des Ausführungsbeispiels nach der Fig. 2 erkennt. Auf diese Weise wird einerseits der Spalt S verschlossen und können andererseits in der Kabelwanne 7 problemlos Kabel bzw. Elektrokabel platziert werden.In this way, a gap S is established between a rear or attachment wall-side longitudinal edge of the table top 1 and the surface element 4 facing the furniture, which gap S is closed in the context of the exemplary embodiment with an additional cable trough 7 in plan view. For this purpose, the cable trough 7 is connected to a lower broad side of the rectangular frame 3 or to the two narrow sides, as are the two angles 6a, 6b. In addition, the design is made such that the cable trough 7 runs below the two angles 6a, 6b. The cable trough 7 has a total width which corresponds to the length of the bridging leg 6a of the angle 6a, 6b or exceeds this, as can be seen from the exemplary embodiment according to FIG Fig. 2 recognizes. In this way, on the one hand, the gap S is closed and, on the other hand, cables or electrical cables can be placed in the cable trough 7 without any problems.

Außerdem besteht die Möglichkeit, dass über den Rahmen 3 eine elektrische Versorgung einzelner Geräte erfolgt oder erfolgen kann. Dazu nimmt der als Hohlprofilrahmen ausgebildete Rahmen im Innern elektrische Zuleitungen für Anschlussbuchsen, elektrische Geräte, Leuchten etc. auf, wie dies einleitend bereits beschrieben worden ist. Tatsächlich mag der Rahmen 3 mit den entsprechenden und nicht ausdrücklich dargestellten Anschlussbuchsen für insbesondere Niedervolt-Geräte 9 ausgerüstet sein. Das deutet die Fig. 1 ergänzend an.There is also the possibility that an electrical supply of individual devices takes place or can take place via the frame 3. For this purpose, the frame, which is designed as a hollow profile frame, accommodates electrical leads for connection sockets, electrical devices, lights, etc. inside, as has already been described in the introduction. In fact, the frame 3 may be equipped with the corresponding and not expressly shown connection sockets for low-voltage devices 9 in particular. The interprets Fig. 1 in addition to.

Das fragliche Niedervolt-Gerät 9 wird dabei nach dem Ausführungsbeispiel in der Fig. 1 im Innern eines Metalleinsatzes aufgenommen. Anstelle des Metalleinsatzes kann hier aber auch ein Schließfach oder ein Safe realisiert werden. Dadurch besteht für einen Bediener die Möglichkeit, persönliche Dinge an seinem Arbeitsplatz diebstahlsicher zu verwahren. Im Übrigen ist das jeweilige Flächenelement 4, 5 aufgrund seiner Steifigkeit in der Lage, einen betreffenden Einsatz bzw. Metalleinsatz oder sogar das angesprochene Schließfach oder einen kleinen Safe tragen und halten zu können.The low-voltage device 9 in question is according to the exemplary embodiment in FIG Fig. 1 recorded inside a metal insert. Instead of the metal insert, a locker or a safe can also be implemented here. This gives an operator the opportunity to keep personal things safe from theft at his workplace. Moreover, due to its rigidity, the respective surface element 4, 5 is able to carry and hold a relevant insert or metal insert or even the mentioned locker or a small safe.
