Description

Die Erfindung betrifft ein Montagesystem zur thermisch entkoppelten Montage von Leuchten und ein entsprechendes Leuchtensystem.The invention relates to a mounting system for the thermally decoupled assembly of lights and a corresponding lighting system.

Herkömmlich werden Einbauleuchten für abgehängte Decken und Wände direkt an einem Ausschnitt der abgehängten Decke bzw. Wand angebracht. Dabei muss zunächst der Trockenbauer einen Ausschnitt vorbereiten, in welchem anschließend der Elektriker die Leuchte montiert. Anschließend muss erneut der Trockenbauer die Leuchte bündig mit der Oberfläche einputzen. Diese Lösung ist nicht nur aufwendig, da die beiden Gewerke ineinander greifen müssen, sondern neigt auch zur Rissbildung an den Kanten des Ausschnitts und insbesondere in den Ecken des Ausschnitts, da das Leuchtengehäuse thermisch nicht von der verputzten Oberfläche entkoppelt ist.Conventionally, recessed lights for suspended ceilings and walls are attached directly to a section of the suspended ceiling or wall. The drywall builder first has to prepare a section in which the electrician then installs the luminaire. Then the drywall builder has to plaster the luminaire flush with the surface again. This solution is not only expensive, since the two trades need to interlock, but also tends to crack on the edges of the cut and especially in the corners of the cutout, since the luminaire housing is not thermally decoupled from the plastered surface.

So zeigt die internationale Patentanmeldung WO 2014/020015 A1 ein Montagesystem für Leuchten, bei welchem eine direkte feste Verbindung der Kanten eines Ausschnitts, in welchem die Leuchte montiert werden soll, zu dem Leuchtengehäuse besteht. Die dort gezeigte Lösung erfordert einen hohen Montageaufwand und neigt zur Rissbildung entlang der Kanten und insbesondere der Ecken des Ausschnitts.This is shown in the international patent application WO 2014/020015 A1 a mounting system for luminaires, in which a direct firm connection of the edges of a cutout, in which the luminaire is to be mounted, to the luminaire housing consists. The solution shown there requires a high assembly cost and tends to crack along the edges and in particular the corners of the cutout.

Das Dokument US 2004/177572 A1 zeigt eine Aufhängevorrichtung für Leuchten in abgehängten Decken. Die Aufhängevorrichtung besteht dabei aus einem um eine Öffnung in der Decke umlaufenden Profil mit einem ersten Schenkel, welcher an der Unterseite der abhängten Decke angebracht ist, und einem zweiten Schenkel, welcher in die Öffnung hineinragt. Der zweite Schenkel ist dabei direkt an der Kante der Öffnung angebracht. Die Leuchte wird dabei von unten in die von der Aufhängevorrichtung ausgekleidete Öffnung eingesetzt und rastet mittels Federelementen in einen oberen Rand der zweiten Schenkel ein.The document US 2004/177572 A1 shows a suspension device for lights in suspended ceilings. The suspension device consists of a circumferential around an opening in the ceiling profile with a first leg, which is attached to the underside of the suspended ceiling, and a second leg, which projects into the opening. The second leg is attached directly to the edge of the opening. The luminaire is inserted from below into the opening which is lined by the suspension device and engages by means of spring elements in an upper edge of the second leg.

Das Dokument US 2005/002182 A1 zeigt eine Leuchte und ein Montagesystem für eine Leuchte zur Montage in abgehängten Decken. Dabei sind an den Rändern der abgehängten Decke 121 Montageschienen angeordnet, welche über einen ersten Schenkel verfügen, welcher parallel zu der Unterseite der abgehängten Decke verläuft, und welche über einen zweiten Schenkel verfügen, welcher in die Öffnung in der abgehängten Decke eingreift. Verbunden mit den Montageschienen ist ein mehrteiliges Gehäuse, in welches ein Leuchtenmodul eingesetzt werden kann.The document US 2005/002182 A1 shows a lamp and a mounting system for a luminaire for mounting in suspended ceilings. In this case, 121 mounting rails are arranged at the edges of the suspended ceiling, which have a first leg which extends parallel to the underside of the suspended ceiling, and which have a second leg which engages in the opening in the suspended ceiling. Connected to the mounting rails is a multi-part housing, in which a lamp module can be used.

Das Dokument WO 2005/124054 A1 zeigt ein Montagesystem für Leuchten in abgehängten Decken. Dabei wird ein umlaufender Rahmen bestehend aus einer Aufnahmeschiene in einer Öffnung der abgehängten Decke platziert. Die Aufnahmeschiene ist dabei L-förmig ausgebildet. Ein erster Schenkel liegt auf der Unterseite der abgehängten Decke auf, während ein zweiter Schenkel rechtwinklig dazu angeordnet ist und in die Öffnung greift. Der zweite Schenkel ist dabei bündig mit der Kante der Öffnung in der abgehängten Decke angeordnet. Die Leuchte wird dabei von Halterungen gehalten, welche parallel zu den ersten Schenkeln in die Öffnung hineinragen.The document WO 2005/124054 A1 shows a mounting system for luminaires in suspended ceilings. In this case, a peripheral frame is placed consisting of a receiving rail in an opening of the suspended ceiling. The receiving rail is formed L-shaped. A first leg rests on the underside of the suspended ceiling, while a second leg is perpendicular thereto and engages the opening. The second leg is arranged flush with the edge of the opening in the suspended ceiling. The lamp is held by brackets, which protrude parallel to the first legs in the opening.

Der Erfindung liegt somit die Aufgabe zugrunde, ein Montagesystem zur Montage von Leuchten zu schaffen, welches einen geringen Montageaufwand erfordert und gleichzeitig eine hohe Lebensdauer gewährleistet.The invention is therefore an object of the invention to provide a mounting system for mounting luminaires, which requires a low installation cost and at the same time ensures a long service life.

Die Aufgabe wird erfindungsgemäß für die Vorrichtung durch die Merkmale des unabhängigen Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen sind Gegenstand der hierauf rückbezogenen Unteransprüche.The object is achieved for the device by the features of independent claim 1. Advantageous developments are the subject of the dependent claims.

Ein erfindungsgemäßes Montagesystem zur Montage einer Leuchte weist zwei im Wesentlichen L-förmig ausgebildete Aufnahmeschienen auf. Die Aufnahmeschienen verfügen dabei jeweils über einen ersten Schenkel, welcher ausgebildet ist, um an einer Vorderseite einer abgehängten Wand oder einer Unterseite einer abgehängten Decke an jeweils einer gegenüberliegenden Kante eines Ausschnitts der Wand bzw. Decke befestigt zu werden. Die Aufnahmeschienen weisen weiterhin jeweils einen zweiten Schenkel auf, welcher ausgebildet ist, um in den Ausschnitt hineinzugreifen bzw. hineinzuragen und ein Leuchtengehäuse der Leuchte zu tragen, ohne das Leuchtengehäuse jedoch starr mit den ersten Schenkeln der Aufnahmeschienen zu verbinden. So wird erreicht, dass sich das Leuchtengehäuse thermisch ausdehnen und zusammenziehen kann, ohne dass diese Bewegung auf die Aufnahmeschienen und damit die Ränder des Ausschnitts übertragen werden. Auch eine einfache Montage wird so erreicht. Vorzugsweise sind die Aufnahmeschienen ausgebildet, um in einem definierten ersten Abstand zueinander, gemessen zwischen den zweiten Schenkeln, angeordnet zu werden. Die Ränder des Ausschnitts sind in diesem Fall in einem zweiten Abstand, welcher größer ist als der erste Abstand, zueinander angeordnet. Es ergeben sich damit Abstände zwischen den zweiten Schenkeln der Aufnahmeschienen und den Rändern des Ausschnitts. Diese Abstände sorgen dafür, dass eine besonders gute thermische Entkopplung zwischen den Rändern des Ausschnitts und dem Leuchtengehäuse entsteht. Darüber hinaus wird auch eine zusätzliche mechanische Entkopplung erreicht.An inventive mounting system for mounting a lamp has two substantially L-shaped receiving rails. The receiving rails each have a first leg, which is designed to be attached to a front side of a suspended wall or a bottom of a suspended ceiling on each opposite edge of a section of the wall or ceiling. The Receiving rails furthermore each have a second leg, which is designed to engage or project into the cutout and to carry a luminaire housing of the luminaire, but without rigidly connecting the luminaire housing to the first legs of the receiving rails. This ensures that the luminaire housing can thermally expand and contract without this movement being transmitted to the receiving rails and thus the edges of the cutout. Even a simple installation is achieved. Preferably, the receiving rails are designed to be arranged at a defined first distance from each other, measured between the second legs. The edges of the cutout are in this case at a second distance, which is greater than the first distance, arranged to each other. This results in distances between the second legs of the receiving rails and the edges of the cutout. These distances ensure that a particularly good thermal decoupling is created between the edges of the cutout and the luminaire housing. In addition, an additional mechanical decoupling is achieved.

Die zweiten Schenkel der Aufnahmeschienen weisen Aufnahmen, Auskragungen bzw. Profilierungen, auf, welche ausgebildet sind, um das Leuchtengehäuse zu tragen, ohne das Leuchtengehäuse starr mit den ersten Schenkeln der Aufnahmeschienen zu verbinden. So kann eine besonders einfache Montage erreicht werden.The second legs of the receiving rails have receptacles, projections or profilings, which are designed to support the luminaire housing, without rigidly connecting the luminaire housing to the first legs of the mounting rails. So a particularly simple installation can be achieved.

Die Aufnahmen sind bevorzugt ausgebildet, um das Leuchtengehäuse schwimmend zu tragen. Alternativ oder zusätzlich sind die zweiten Schenkel der Aufnahmeschienen derart flexibel ausgebildet, dass sie eine thermische Größenveränderung des Leuchtengehäuses ausgleichen, ohne diese an die ersten Schenkel der Aufnahmeschienen oder an Ränder des Ausschnitts zu übertragen. So wird eine Rissbildung auch durch mechanische Maßnahmen, insbesondere eine mechanische Entkopplung, vermieden.The receptacles are preferably designed to float the luminaire housing. Alternatively or additionally, the second legs of the receiving rails are formed so flexible that they compensate for a thermal change in size of the lamp housing, without them to the first leg of the receiving rails or edges of the cutout to transfer. Thus, crack formation is also avoided by mechanical measures, in particular mechanical decoupling.

Die Aufnahmen sind weiterhin bevorzugt ausgebildet, um das Leuchtengehäuse und die Aufnahmeschienen thermisch zu entkoppeln. So wird eine Wärmeübertragung in die Aufnahmeschienen und damit in die Ränder des Ausschnitts vermieden. Eine Rissbildung durch Ausdehnung der Aufnahmeschienen und/oder der Ränder des Ausschnitts wird somit vermieden.The recordings are furthermore preferably designed to thermally decouple the luminaire housing and the receiving rails. Thus, a heat transfer is avoided in the receiving rails and thus in the edges of the cutout. Cracking due to expansion of the receiving rails and / or the edges of the cutout is thus avoided.

Bevorzugt weisen die Aufnahmeschienen Einputzkanten auf, welche ausgebildet sind, um ein bündiges Verputzen der ersten Schenkel mit einer Oberfläche der Wand bzw. Decke zu ermöglichen. So wird eine besonders saubere Oberflächengestaltung ermöglicht. Darüber hinaus wird dadurch ermöglicht, dass der Trockenbauer sein Gewerk vollständig vollenden kann bevor der Elektriker sein Gewerk beginnt.Preferably, the receiving rails on Einputzkanten, which are designed to allow a flush plastering of the first leg with a surface of the wall or ceiling. This enables a particularly clean surface design. In addition, this allows the drywaller to complete his craft completely before the electrician starts his trade.

Vorzugsweise verfügt das Montagesystem weiterhin über zwei Randaufnahmeplatten, welche ausgebildet sind, um in Endbereichen des Ausschnitts angebracht zu werden, die Aufnahmeschienen vorzugsweise zu verbinden, und die Endbereiche des Ausschnitts thermisch von den Aufnahmeschienen zu entkoppeln. Unter 'verbinde' wird hier nicht zwingend eine mechanische Verbindung verstanden, sondern gegebenenfalls auch eine rein optische Verbindung; dass sich die Randaufnahmeplatten also wenigstens im Wesentlichen über die Gesamtbreite beider Aufnahmeschienen bzw. beider erster Schenkel erstreckt. Die Randaufnahmeplatten sind insbesondere vorteilhaft, da der häufigste Entstehungsort eines Risses die Ecke eines Ausschnitts ist. Durch eine (mechanische und) thermische Entkopplung der Ecken des Ausschnitts, welche von den Randaufnahmeplatten umfasst werden, kann eine Rissbildung noch besser vermieden werden.Preferably, the mounting system further comprises two edge receiving plates which are adapted to be mounted in end portions of the cutout, preferably to connect the receiving rails, and to thermally decouple the end portions of the cutout from the receiving rails. By 'connection' here is not necessarily understood a mechanical connection, but possibly also a purely optical connection; that the edge receiving plates thus extends at least substantially over the entire width of both receiving rails or both first leg. The edge receiving plates are particularly advantageous because the most common place of origin of a crack is the corner of a cutout. By a (mechanical and) thermal decoupling of the corners of the cutout, which are covered by the edge receiving plates, cracking can be even better avoided.

Bevorzugt sind die zweiten Schenkel der Aufnahmeschienen weiterhin ausgebildet, um Abdeckungen und/oder Optiken und/oder andere Bauteile - in einer Ebene der Wand bzw. Decke - zu halten. Hierzu können bspw. entweder die zuvor erwähnten Aufnahmen oder zusätzliche Aufnahmen (Profilierungen etc.) der zweiten Schenkel wenigstens als Anschlag der einzusetzenden Abdeckung/Optik in Einsetzrichtung gesehen dienen. So kann eine besonders große Montageflexibilität erreicht werden. Insbesondere kann so auf zusätzliche Halterungen für Abdeckungen, Optiken, etc. verzichtet werden.Preferably, the second legs of the receiving rails are further configured to hold covers and / or optics and / or other components - in a plane of the wall or ceiling. For this purpose, for example. either the aforementioned recordings or additional recordings (profilings, etc.) of the second legs serve at least as an abutment of the cover / optics to be used in the insertion direction. In this way, a particularly high degree of assembly flexibility can be achieved. In particular, so can be dispensed with additional brackets for covers, optics, etc.

Ein erfindungsgemäßes Leuchtensystem beinhaltet ein zuvor beschriebenes Montagesystem, eine Leuchte mit einem Leuchtengehäuse und eine abgehängte Decke bzw. Wand. Die Aufnahmeschienen sind dabei mit ihrem jeweiligen ersten Schenkel an einer Vorderseite der abgehängten Wand oder einer Unterseite der abgehängten Decke an gegenüberliegenden Rändern eines Ausschnitts der Wand bzw. Decke befestigt. Die zweiten Schenkel der Aufnahmeschienen greifen dabei in den Ausschnitt ein bzw. ragen in diesen hinein und tragen das Leuchtengehäuse, ohne das Leuchtengehäuse starr mit den ersten Schenkeln der Aufnahmeschienen zu verbinden. Eine einfache Montage wird damit erreicht, während gleichzeitig eine wand- bzw. deckenseitige Rissbildung vermieden wird.An inventive lighting system includes a previously described mounting system, a lamp with a lamp housing and a suspended ceiling or wall. The receiving rails are fastened with their respective first leg to a front side of the suspended wall or an underside of the suspended ceiling at opposite edges of a section of the wall or ceiling. The second leg of the receiving rails engage in the cut or protrude into this and carry the lamp housing without rigidly connect the lamp housing with the first legs of the receiving rails. A simple assembly is achieved while at the same time a wall or ceiling cracking is avoided.

Bevorzugt verfügt das Leuchtensystem über eine Gehäuseaufnahme, welche auf einer Rückseite der Wand bzw. Decke im Bereich des Ausschnitts angeordnet ist, das Leuchtengehäuse umfasst und/oder trägt und den Ausschnitt gegenüber der Rückseite der Wand bzw. Decke abschließt. So wird erreicht, dass die Aufnahmeschienen nicht die (gesamte) Last des Leuchtengehäuses tragen müssen. Eine besonders einfache mechanische und thermische Entkopplung ist damit möglich.Preferably, the lighting system has a housing receptacle, which is arranged on a rear side of the wall or ceiling in the region of the cutout, which comprises and / or carries the luminaire housing and closes the cutout with respect to the rear side of the wall or ceiling. This ensures that the mounting rails do not have to carry the (entire) load of the lamp housing. A particularly simple mechanical and thermal decoupling is possible.

Nachfolgend wird die Erfindung anhand der Zeichnung, in der ein vorteilhaftes Ausführungsbeispiel der Erfindung dargestellt ist, beispielhaft beschrieben. In der Zeichnung zeigen:

A second embodiment of the mounting system according to the invention in a three-dimensional detail view.

Anhand der Fig. 1 und 2 wird auf den detaillierten Aufbau und die Funktionsweise des erfindungsgemäßen Montagesystems und des erfindungsgemäßen Leuchtensystems eingegangen. Identische Elemente wurden in ähnlichen Abbildungen zum Teil nicht wiederholt dargestellt und beschrieben.Based on Fig. 1 and 2 will be discussed the detailed structure and operation of the mounting system and the lighting system according to the invention. Identical elements have not been repeatedly shown and described in similar figures.

In Fig. 1 ist ein erstes Ausführungsbeispiel des erfindungsgemäßen Leuchtensystems gezeigt. Das Leuchtensystem beinhaltet ein Leuchtengehäuse 10, welches im Bereich eines Ausschnitts 3 einer abgehängten Decke 2 oberhalb der abgehängten Decke 2 montiert ist. Das Leuchtengehäuse 10 wird dabei von L-förmigen Aufnahmeschienen 4a und 4b in Position gehalten. Die Aufnahmeschienen 4a und 4b sind dabei Teil des erfindungsgemäßen Montagesystems 1. Die Aufnahmeschienen 4a und 4b weisen dabei jeweils einen ersten Schenkel 5a und 5b auf, mit welchem sie auf der Unterseite der abgehängten Decke 2 angebracht sind. Sie können dabei zum Beispiel geschraubt oder getackert sein. Die Aufnahmeschienen weisen weiterhin jeweils einen zweiten Schenkel 6a und 6b auf, welcher in den Ausschnitt 3 eingreift bzw. in diesen hineinragt und das Leuchtengehäuse 10 trägt, ohne das Leuchtengehäuse 10 starr mit den ersten Schenkeln 5a und 5b der Aufnahmeschienen 4a und 4b zu verbinden; mithin also das Leuchtengehäuse 10 'schwimmend' trägt. Insbesondere wird das Leuchtengehäuse 10 dabei von Auskragungen bzw. Profilierungen 7a und 7b der zweiten Schenkel 6a und 6b, welche Aufnahmen bilden, getragen.In Fig. 1 a first embodiment of the luminaire system according to the invention is shown. The lighting system includes a light housing 10, which is mounted in the region of a section 3 of a suspended ceiling 2 above the suspended ceiling 2. The luminaire housing 10 is held in position by L-shaped receiving rails 4a and 4b. The receiving rails 4a and 4b are part of the mounting system according to the invention 1. The receiving rails 4a and 4b each have a first leg 5a and 5b, with which they are mounted on the underside of the suspended ceiling 2. For example, they can be screwed or stapled. The receiving rails further each have a second leg 6a and 6b, which engages in the cutout 3 and projects into this and the lamp housing 10 carries without the lamp housing 10 rigidly connected to the first legs 5a and 5b of the receiving rails 4a and 4b; So therefore the lamp housing 10 'floating' carries. In particular, the luminaire housing 10 is supported by protrusions or profilings 7a and 7b of the second legs 6a and 6b, which form receptacles.

Der Ausschnitt 3 weist dabei im Bereich der Aufnahmeschienen 4a und 4b einen Abstand d2 auf, während die zweiten Schenkel 6a und 6b der Aufnahmeschienen 4a und 4b zueinander einen Abstand d1 aufweisen. Der Abstand d1 der zweiten Schenkel 6a und 6b zueinander ist dabei geringer als die Breite d2 des Ausschnitts 3. Der Abstand d1 ist somit kleiner als der Abstand d2. Dadurch wird erreicht, dass sich zwischen den zweiten Schenkel 6a und 6b und den Rändern des Ausschnitts 3 Abstände 9a und 9b bilden. Die Abstände 9a und 9b unterstützen eine thermische Entkopplung des Leuchtengehäuses 10 von den Rändern des Ausschnitts 3 der abgehängten Decke 2. Darüber hinaus können die zweiten Schenkel 6a und 6b derart flexibel ausgebildet sein, dass sie bei Bedarf thermische Ausdehnungen des Leuchtengehäuses durch seitliche Bewegung in die Abstände 9a und 9b hinein oder in entgegengesetzter Richtung ausgleichen können.The cutout 3 has a spacing d2 in the region of the receiving rails 4a and 4b, while the second legs 6a and 6b of the receiving rails 4a and 4b have a distance d1 from one another. The distance d1 of the second legs 6a and 6b from each other is less than the width d2 of the section 3. The distance d1 is thus smaller than the distance d2. As a result, spacings 9a and 9b are formed between the second legs 6a and 6b and the edges of the cutout 3. The Distances 9a and 9b support a thermal decoupling of the lamp housing 10 from the edges of the cutout 3 of the suspended ceiling 2. In addition, the second legs 6a and 6b may be formed so flexible that they if necessary thermal expansions of the lamp housing by lateral movement in the distances 9a and 9b in or in the opposite direction can compensate.

Des Weiteren ermöglichen es die Aufnahmeschienen 4a und 4b, dass über den ersten Schenkel 5a und 5b die Abstände 9a und 9b sicher ausgeglichen werden können. Auf diese Weise kann - im Gegensatz zu der herkömmlichen Befestigungsweise - der Ausschnitt 3 mit mehr Spiel bereitgestellt werden, was den Einbau des erfindungsgemäßen Systems vereinfacht.Furthermore, the receiving rails 4a and 4b make it possible for the distances 9a and 9b to be reliably compensated via the first legs 5a and 5b. In this way, in contrast to the conventional manner of fastening, the cutout 3 can be provided with more play, which simplifies installation of the system according to the invention.

Die Aufnahmeschienen 4a und 4b weisen darüber hinaus Einputzkanten 8a und 8b auf, welche ein bündiges Einputzen der ersten Schenkel 5a und 5b der Aufnahmeschienen 4a und 4b mit der Unterseite der abgehängten Decke 2 ermöglichen. Die Einputzkanten 8a und 8b weisen hierzu im eingebauten Zustand des Systems von der abgehängten Decke 2 weg (nach unten), also im Wesentlichen quer zu den ersten Schenkel oder längs zu den zweiten Schenkeln. Insbesondere wird so erreicht, dass der Trockenbauer sein Gewerk durch Montage der Aufnahmeschienen 4a und 4b und anschließendem Einputzen der Aufnahmeschienen 4a und 4b an den Einputzkanten 8a und 8b vollständig abschließen kann. Die Montage des Leuchtengehäuses 10 kann durch den Elektriker erfolgen, ohne dass der Trockenbauer noch einmal nacharbeiten muss.The receiving rails 4a and 4b also have plastering edges 8a and 8b, which allow a flush plastering of the first legs 5a and 5b of the receiving rails 4a and 4b with the underside of the suspended ceiling 2. The Einputzkanten 8a and 8b have this in the installed state of the system of the suspended ceiling 2 away (down), ie substantially transversely to the first leg or longitudinally to the second legs. In particular, it is achieved that the drywall can complete his trade by mounting the receiving rails 4a and 4b and then plastering the receiving rails 4a and 4b on the plaster edges 8a and 8b completely. The assembly of the lamp housing 10 can be done by the electrician, without the drywall has to rework again.

Die zweiten Schenkel 6a und 6b der Aufnahmeschienen 4a und 4b sind dabei zusätzlich ausgebildet, um weitere Bauelemente wie zum Beispiel Optiken oder Abdeckungen einer Leuchte im Bereich der Ebene der abgehängten Decke 2 zu halten. So können Ausschnitte 3, welche gerade nicht für eine Leuchte genutzt werden, einfach abgedeckt werden. Alternativ können Ausschnitte 3, welche gerade für eine Leuchte genutzt werden, sehr einfach mit einer Optik versehen werden, welche dann nicht in die Leuchte integriert werden muss.The second legs 6a and 6b of the receiving rails 4a and 4b are additionally designed to hold other components such as optics or covers a lamp in the plane of the suspended ceiling 2. So cutouts 3, which are currently not used for a lamp, can be easily covered. Alternatively, cutouts 3, which are currently being used for a luminaire, can very easily be provided with an optic which then does not have to be integrated into the luminaire.

Vorzugsweise weist das Leuchtensystem, welches hier dargestellt ist, zusätzlich eine Gehäuseaufnahme 12 auf, welche auf der Oberseite der abgehängten Decke im Bereich des Ausschnitts 3 angeordnet ist. Die Gehäuseaufnahme 12 umfasst dabei das Leuchtengehäuse 10 und trägt es optional zusätzlich. Darüber hinaus schließt die Gehäuseaufnahme 12 den Ausschnitt 3 gegenüber der Rückseite der abgehängten Decke 2 ab.Preferably, the light system, which is shown here, in addition to a housing receptacle 12, which is arranged on the top of the suspended ceiling in the region of the cutout 3. The housing receptacle 12 in this case comprises the luminaire housing 10 and optionally carries it in addition. In addition, the housing receptacle 12 closes the cutout 3 with respect to the rear side of the suspended ceiling 2.

In dem hier dargestellten Ausführungsbeispiel wurde stets von einer abgehängten Decke gesprochen. Dies ist jedoch nicht als Einschränkung zu verstehen. Bei den Elementen 2 kann es sich ebenso um eine abgehängte Wand und dergleichen handeln.In the embodiment shown here was always spoken by a suspended ceiling. However, this is not meant to be limiting. The elements 2 may also be a suspended wall and the like.

In Fig. 2 ist ein zweites Ausführungsbeispiel des erfindungsgemäßen Montagesystems 1 in einer dreidimensionalen Ansicht gezeigt. Hier wurde der Übersichtlichkeit halber auf eine Darstellung des Leuchtengehäuses und der Gehäuseaufnahme verzichtet.In Fig. 2 a second embodiment of the mounting system 1 according to the invention is shown in a three-dimensional view. Here, for the sake of clarity, a representation of the luminaire housing and the housing receptacle has been omitted.

Seitliche Ränder des Ausschnitts 3 sind hier durch die Aufnahmeschienen 4a und 4b mit dem in Fig. 1 dargestellten Abstand 9a und 9b verdeckt.Lateral edges of the cutout 3 are here by the receiving rails 4a and 4b with the in Fig. 1 hidden distance 9a and 9b hidden.

Hier ist zusätzlich eine in Fig. 1 nicht dargestellte Randaufnahmeplatte 13 gezeigt, welche in einem Endbereich des Ausschnitts 3 angebracht ist und die Aufnahmeschienen 4a und 4b vorzugsweise verbindet oder sich wenigstens quer über den Ausschnitt 3 erstreckt, vorzugsweise wenigstens im Wesentlichen über die gesamte Breite der Aufnahmeschienen 4a und 4b bzw. deren ersten Schenkeln 5a und 5b. Im letztgenannten Fall kann die Randaufnahmeplatte 13 sogar leicht von den Aufnahmeschienen 4a und 4b beabstandet sein; bspw. um einen Dehnungsspalt zu den Aufnahmeschienen 4a und 4b bereitzustellen. Die Randaufnahmeplatte 13 dient dabei zur zusätzlichen (mechanischen und) thermischen Trennung des für Risse besonders empfindlichen Randbereichs des Ausschnitts 3 von den Aufnahmeschienen 4a und 4b. In Fig. 2 ist lediglich ein einzelner Randbereich des Ausschnitts 3 dargestellt. Selbstverständlich ist eine entsprechende Randaufnahmeplatte auch an dem gegenüberliegenden Rand des Ausschnitts 3 anzubringen bzw. anbringbar. Dies wurde der Übersichtlichkeit halber hier jedoch nicht dargestellt.Here is an additional in Fig. 1 Not shown edge receiving plate 13 is shown, which is mounted in an end portion of the cutout 3 and the receiving rails 4a and 4b preferably connects or extends at least transversely across the cutout 3, preferably at least substantially over the entire width of the receiving rails 4a and 4b and their first Legs 5a and 5b. In the latter case, the edge receiving plate 13 may even be slightly spaced from the receiving rails 4a and 4b; For example, to provide an expansion gap to the receiving rails 4a and 4b. The edge receiving plate 13 serves for additional (mechanical and) thermal separation of the edge region of the cutout 3, which is particularly sensitive to cracks, from the receiving rails 4a and 4b. In Fig. 2 only a single edge region of the section 3 is shown. Of course, a corresponding edge receiving plate is also on the opposite edge of the cutout 3 to attach or attach. However, this was not shown here for the sake of clarity.

Die Erfindung ist nicht auf das dargestellte Ausführungsbeispiel beschränkt. Wie bereits erwähnt, kann das erfindungsgemäße Montagesystem in jeglichen abgehängten Oberflächen eingesetzt werden. Auch kann es zur Montage anderer Bauelemente als Leuchten genutzt werden. Alle vorstehend beschriebenen Merkmale oder in den Figuren gezeigten Merkmale sind im Rahmen der Erfindung beliebig vorteilhaft miteinander kombinierbar. Ferner ist es denkbar, dass die zwei zusammenwirkenden Aufnahmeschienen in mehrere Segmente in Längsrichtung derselben gesehen unterteilt sind. Die Randaufnahmeplatten können dann an der jeweils äußersten Aufnahmeschiene und/oder auch an beliebigen Stoßbereichen zweier Aufnahmeschienen vorgesehen sein.The invention is not limited to the illustrated embodiment. As already mentioned, the mounting system according to the invention can be used in any suspended surfaces. It can also be used for mounting other components as lights. All features described above or features shown in the figures can be combined with each other in any advantageous manner within the scope of the invention. Furthermore, it is conceivable that the two cooperating receiving rails are divided into a plurality of segments viewed in the longitudinal direction thereof. The edge receiving plates can then be provided on the respective outermost receiving rail and / or on any desired impact areas of two receiving rails.
