Nach Einsetzen des Einbaurahmens in die Öffnung einer abgehängten Decke müssen also die Federelemente in die Montageposition gedreht und dort eingerastet werden.A similar solution for the realization of a mounting device for a recessed ceiling or ceiling luminaire is in the WO 2005/022033 A1 described. Again, the mounting device consists essentially of a mounting frame and a plurality of clamping or spring elements located thereon, wherein the spring elements are each rotatably supported on the mounting frame. Each spring element here consists of a first part in the form of a flexible tongue and a second part in the form of a retaining element. This retaining element has snap hooks in a final assembly position the spring element, in which this is brought by rotation, cooperate with corresponding locking elements of the mounting frame. After inserting the mounting frame in the opening of a suspended ceiling so the spring elements must be turned into the mounting position and locked there.

Auch in der EP 1 577 611 A2 und in der EP 1 348 903 A1 sind Möglichkeiten gezeigt, bei denen mit Hilfe von entsprechenden Montagevorrichtungen der Einbau von Leuchten in abgehängte Decken erleichtert bzw. ermöglicht wird.Also in the EP 1 577 611 A2 and in the EP 1 348 903 A1 Possibilities are shown in which facilitated with the help of appropriate mounting devices, the installation of lights in suspended ceilings or enabled.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ausgehend von dem zuvor genannten Stand der Technik eine neuartige Lösung anzugeben, welche ein einfaches Montieren und Demontieren von Downlights in einer abgehängten Decke ermöglicht.The present invention has for its object, starting from the aforementioned prior art to provide a novel solution that allows easy mounting and dismounting of downlights in a suspended ceiling.

Die Aufgabe wird durch eine Montagevorrichtung, welche die Merkmale des Anspruchs 1 aufweist gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.The object is achieved by a mounting device having the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.

Die erfindungsgemäße Lösung beruht auf der Verwendung eines neuartigen Rastelements, mit dessen Hilfe der Einbaurahmen in der Decke in komfortabler Weise fixiert werden kann. Hierzu ist vorgesehen, dass das Rastelement bistabil ausgebildet ist, also zwei stabile Zustände aufweist. Ein erster stabiler Zustand des Rastelements ermöglicht hierbei das Einsetzen des Einbaurahmens in die Deckenöffnung bzw. das Entnehmen des Einbaurahmens bei der Demontage, während hingegen der zweite stabile Zustand dazu führt, dass der Einbaurahmen mit Hilfe des Rastelements in der Decke fixiert ist.The solution according to the invention is based on the use of a novel locking element, with the aid of which the mounting frame can be fixed in the ceiling in a comfortable manner. For this purpose, it is provided that the latching element is formed bistable, that has two stable states. A first stable state of the locking element in this case allows the insertion of the mounting frame in the ceiling opening and the removal of the mounting frame during disassembly, while the second stable state causes the mounting frame is fixed by means of the locking element in the ceiling.

Erfindungsgemäß wird dementsprechend eine Montagevorrichtung für eine Deckeneinbauleuchte vorgeschlagen, welche einen Einbaurahmen, der zum Einsetzen in die Öffnung einer Decke bestimmt ist und Mittel zur Halterung der Leuchte aufweist, sowie mindestens ein Rastelement zum Fixieren des Einbaurahmens in der Decke aufweist. Erfindungsgemäß ist hierbei das Rastelement derart bistabil ausgebildet, dass es zwei stabile Zustände einnehmen kann, wobei es von einem ersten stabilen Zustand, in dem das Einsetzen des Einbaurahmens in die Deckenöffnung bzw. das Entnehmen des Einbaurahmens aus der Deckenöffnung ermöglicht ist, in einen zweiten stabilen Zustand, in dem der Einbaurahmen in der Decke fixiert ist, überführbar ist, wobei das Rastelement verformbar, insbesondere verbiegbar ist und eine Feder aufweist, über welche das Rastelement in den ersten stabilen Zustand oder den zweiten stabilen Zustand vorgespannt ist.According to the invention a mounting device for a recessed ceiling luminaire is accordingly proposed, which has a mounting frame, which is intended for insertion into the opening of a ceiling and has means for holding the lamp, and at least one locking element for fixing the mounting frame in the ceiling. According to the invention, the latching element is designed bistable such that it can assume two stable states, wherein it is from a first stable state in which the insertion of the mounting frame in the ceiling opening or the removal of the mounting frame from the ceiling opening is possible in a second stable State in which the mounting frame is fixed in the ceiling, can be transferred, wherein the locking element deformable, in particular bendable and has a spring, via which the locking element is biased in the first stable state or the second stable state.

Die erfindungsgemäße Lösung zeichnet sich insbesondere durch die hohe Benutzerfreundlichkeit aus. Aufgrund der Bi-Stabilität des Rastelements ist ein einfaches Fixieren des Einbaurahmens in der Decke bzw. ein einfaches Lösen der Verrastung ermöglicht. Ohne hohen Aufwand kann dementsprechend ein Downlight in einer Decke montiert werden, wobei hierfür insbesondere nicht die Nutzung spezieller Werkzeuge erforderlich ist.The solution according to the invention is characterized in particular by the high degree of user-friendliness. Due to the bi-stability of the locking element is a easy fixing of the mounting frame in the ceiling or a simple release of the latch allows. Accordingly, without great effort, a downlight can be mounted in a ceiling, in which case, in particular, it is not necessary to use special tools.

Die abhängigen Ansprüche betreffen insbesondere die Ausgestaltung des Rastelements, wobei dieses vorzugsweise zwei Flügelarme aufweist, welche an ihrem einen Ende an dem Einbaurahmen befestigt und an ihrem anderen Ende über die Feder, bei der es sich insbesondere um eine Spiralfeder handeln kann, miteinander verbunden sind. An ihren Außenseiten können die Flügelarme Rastvorsprünge, insbesondere in Form einer Verzahnung zum Verrasten mit der Decke bzw. einem auf der Decke liegenden Auflageelement aufweisen. Dadurch, dass sich die Verzahnung im wesentlichen über die gesamten Außenseiten der Rastelemente erstreckt, wird ferner auch der Vorteil erzielt, dass sich die Elemente automatisch an verschiedene Deckendicken anpassen. Das System kann also unabhängig von der Dicke bzw. Stärke der abgehängten Decke eingesetzt werden, ohne dass eine Anpassung erforderlich wäre. Dies trägt zusätzlich zur Erhöhung der Nutzerfreundlichkeit bei.The dependent claims relate in particular to the design of the latching element, which preferably has two wing arms which are attached at one end to the mounting frame and at its other end via the spring, which may in particular be a coil spring, are interconnected. On its outer sides, the wing arms can have latching projections, in particular in the form of a toothing for latching to the ceiling or a support element lying on the ceiling. The fact that the toothing extends substantially over the entire outer sides of the locking elements, the advantage is also achieved that the elements automatically adapt to different ceiling thicknesses. The system can therefore be used regardless of the thickness or thickness of the suspended ceiling, without any adaptation would be required. This also adds to the user-friendliness.

Über den Umfang des Einbaurahmens verteilt können mehrere Rastelemente vorgesehen sein. Die Erfindung ist hierbei keines falls auf ringförmige Einbaurahmen beschränkt, sondern kann bei Einbaurahmen jeglicher Form zum Einsatz kommen.Distributed over the circumference of the mounting frame several locking elements can be provided. The invention is in this case not limited to annular mounting frame, but can be used in mounting frame of any shape.

Die in den Figuren allgemein mit dem Bezugszeichen 1 versehene erfindungsgemäße Montagevorrichtung besteht wie bereits erwähnt im Wesentlichen aus zwei verschiedenen Komponenten, einem ringförmigen Einbaurahmen 2 sowie den Rahmen in einer Deckenöffnung 51 fixierenden Rastelementen 10. Entsprechend der Darstellung in Fig. 2 sind im dargestellten Ausführungsbeispiel insbesondere drei Rastelemente 10 vorgesehen, welche über den Umfang des Einbaurahmens 2 verteilt angeordnet sind und gemeinsam diesen in der Decke 50 fixieren. Je nach Form und Größe des Einbaurahmens 2 kann allerdings die Anzahl der Rastelemente 10 auch variieren. Anstelle des dargestellten ringförmigen Einbaurahmens 2 könnten ferner auch anderweitig gestaltete Rahmen, bspw. quadratische oder rechteckige Rahmen an der Decke befestigt werden.As already mentioned, the mounting device according to the invention generally designated by the reference numeral 1 consists essentially of two different components, an annular mounting frame 2 and the frame in a ceiling opening 51 fixing latching elements 10. As shown in FIG Fig. 2 In particular, three locking elements 10 are provided in the illustrated embodiment, which are distributed over the circumference of the mounting frame 2 and fix them together in the ceiling 50. Depending on the shape and size of the mounting frame 2, however, the number of locking elements 10 may also vary. Instead of the illustrated annular mounting frame 2 also otherwise shaped frame, for example. Square or rectangular frame could be attached to the ceiling.

Der Einbaurahmen 2 selbst weist in bekannter Weise einen umlaufenden und nach außen weisenden Flansch 3 auf, der zur Anlage gegen die Unterseite der Decke 50 vorgesehen ist. Von der Innenseite des Flansches 3 erstreckt sich zur Oberseite hin eine umlaufende Wand 4, welche in die Einbauöffnung 51 der Decke 50 hineinragt und einerseits Mittel zum Befestigen der Rastelemente 10 sowie andererseits Mittel zum Befestigen einer Leuchte aufweist. Wie aus dem Stand der Technik bekannt, können zur Leuchtenbefestigung bspw. Mittel vorgesehen sein, durch die eine Bajonettverbindung mit dem zu montierenden Leuchtenkörper erzielt wird. Auf diese Elemente zur Befestigung der Leuchte an dem Einbaurahmen 2 wird im folgenden nicht weiter eingegangen, da derartige Verbindungen bereits aus dem Stand der Technik bekannt sind.The mounting frame 2 itself has in a known manner a circumferential and outwardly facing flange 3, which is provided for abutment against the underside of the ceiling 50. From the inside of the flange 3 extends to the top toward a circumferential wall 4, which projects into the mounting hole 51 of the ceiling 50 and on the one hand has means for securing the locking elements 10 and on the other hand means for fixing a lamp. As known from the prior art, for example, means may be provided for mounting the luminaire, by means of which a bayonet connection with the luminaire body to be mounted is achieved. These elements for mounting the lamp to the mounting frame 2 will not be discussed further in the following, since such compounds are already known from the prior art.

Das erfindungsgemäße System zeichnet sich insbesondere durch die Ausgestaltung der Rastelemente 10 auf, welche nachfolgend näher beschrieben werden sollen und deren Ausgestaltung insbesondere den Fig. 1 bis 5 entnommen werden kann.The system according to the invention is characterized in particular by the design of the latching elements 10, which will be described in more detail below and their design in particular the Fig. 1 to 5 can be removed.

Grundsätzlich gesehen besteht jedes Rastelement 10 aus zwei Flügelarmen 11, welche an ihrer Unterseite über eine Schraubverbindung 20 an dem Einbaurahmen 2 befestigt sind. An ihren oberen Enden weisen die Flügelarme 11 jeweils eine Öse 12 auf, in welche das Ende einer Spiralfeder 15 eingehängt ist. Die Spiralfeder 15 verbindet dementsprechend die beiden oberen Enden der Flügelarme 11 miteinander. Ferner ist an den Außenseiten der Arme 11 jeweils eine Verzahnung 13 ausgebildet, mit deren Hilfe - wie später erläutert - eine Verrastung mit der Decke 50 erzielt werden kann.Basically, each locking element 10 consists of two wing arms 11, which are fastened on its underside via a screw 20 to the mounting frame 2. At their upper ends, the wing arms 11 each have an eyelet 12, in which the end of a coil spring 15 is mounted. The coil spring 15 accordingly connects the two upper ends of the wing arms 11 together. Further, a toothing 13 is formed on the outer sides of the arms 11, with the aid of which - as explained later - a catch with the ceiling 50 can be achieved.

Die Flügelarme 11 bestehen aus einem Material, welches eine gewisse Flexibilität aufweist, so dass die Arme 11 verbiegbar sind. Da die Flügelarme 11 an ihren oberen Endbereichen über die Feder 15 miteinander verbunden sind, ergibt sich hierdurch eine bistabile Ausgestaltung. Dies bedeutet, dass das Rastelement 10 zwei stabile Stellungen einnehmen kann, aus denen es lediglich durch die Ausübung von Kraft gebracht werden kann.The wing arms 11 are made of a material which has a certain flexibility, so that the arms 11 are bendable. Since the wing arms 11 at their upper End regions are connected to each other via the spring 15, this results in a bistable design. This means that the locking element 10 can assume two stable positions, from which it can be brought only by the exercise of force.

Ein erster stabiler Zustand des erfindungsgemäßen Rastelements 10 ist in Fig. 1 dargestellt. Hierbei sind die Federarme 11 in Bezug auf den Einbaurahmen 2 zur Innenseite gewölbt bzw. gebogen. Dieser stabile Zustand zeichnet sich insbesondere dadurch aus, dass das Rastelement 10 mit den beiden Flügelarmen 11 nicht bzw. nur unwesentlich über den Außenumfang der umlaufenden Wand 4 hervorsteht sondern stattdessen zur offenen Innenseite zeigt. In diesem Zustand ist der Einbaurahmen 2 mit den daran befestigten Rastelementen 10 problemlos in die Öffnung 51 der Decke 50 einsetzbar bzw. kann wieder aus der Öffnung 51 entfernt werden.A first stable state of the locking element 10 according to the invention is in Fig. 1 shown. Here, the spring arms 11 are curved or bent with respect to the mounting frame 2 to the inside. This stable state is characterized in particular by the fact that the locking element 10 with the two wing arms 11 does not project or only insignificantly beyond the outer circumference of the peripheral wall 4 but instead points to the open inner side. In this state, the mounting frame 2 with the attached locking elements 10 can be easily inserted into the opening 51 of the ceiling 50 and can be removed again from the opening 51.

Der zweite stabile Zustand der Rastelemente 10 ist in den Fig. 2 bis 5 gezeigt. Hierbei sind die Flügelarme 11 nach außen gebogen bzw. gewölbt. Die an den Außenkanten der Flügelarme 11 ausgebildete Verzahnung 13 gelangt hierbei in Anlage gegen die abgehängte Decke 50, wodurch der Einbaurahmen 2 mit der Decke 50 verrastet wird.The second stable state of the locking elements 10 is in the Fig. 2 to 5 shown. Here, the wing arms 11 are bent or arched outwards. The formed on the outer edges of the wing arms 11 teeth 13 in this case comes into abutment against the suspended ceiling 50, whereby the mounting frame 2 is locked to the ceiling 50.

Grundsätzlich sind die Flügelarme 11 des Rastelements 10 ohne Weiteres von der nach innen gewölbten Konfiguration in die nach außen gewölbte Konfiguration verbiegbar. Durch die Verbindung der oberen Enden der Flügelarme 11 mit Hilfe der Spiralfeder 15 wird allerdings im ausgestreckten Zustand der Flügelarme 11 ein Tot- oder Knickpunkt geschaffen. Bei Überschreiten dieses Punkts wird die Feder 15 automatisch versuchen, die Flügelarme 15 zusammenzuziehen, was je nachdem, an welcher Seite des Knickpunkts sich die Arme 11 befinden, entweder zu dem stabilen Zustand gemäß Fig. 1 oder dem in den Fig. 2 bis 5 dargestellten stabilen Zustand führt. Das Rastelement 10 verharrt dementsprechend entweder in der Position, welche ein Einsetzen bzw. Entnehmen des Einbaurahmens 2 ermöglicht, oder in der Position, in der eine Verrastung mit der Decke 50 erfolgt.Basically, the wing arms 11 of the detent member 10 are readily bendable from the inwardly domed configuration to the outwardly arched configuration. By connecting the upper ends of the wing arms 11 by means of the coil spring 15, however, a dead or break point is created in the extended state of the wing arms 11. When this point is exceeded, the spring 15 will automatically try to contract the wing arms 15, depending on which side of the break point the arms 11 are, either to the stable condition according to FIG Fig. 1 or in the Fig. 2 to 5 shown stable state. The locking element 10 accordingly remains either in the position which allows insertion or removal of the mounting frame 2, or in the position in which a latching with the ceiling 50 takes place.

Bei einer Montage des Einbaurahmens 2 in der Öffnung 51 einer Decke 50 ist also zunächst sicherzustellen, dass sich sämtliche Rastelemente 10 in dem in Fig. 1 dargestellten Zustand befinden, so dass der Einbaurahmen 2 ohne Probleme von der Unterseite her an die Decke 50 angesetzt werden kann. Anschließend werden die Rastelemente 10 zur Außenseite hin gedrückt, was bspw. durch Kraftausübung auf die Spiralfeder 15 erfolgen kann. Nach Überschreiten des oben genannten Knickpunkts schnappen dann die Rastelemente 10 automatisch nach außen und nehmen die in Fig. 2 bis 5 dargestellte Position ein. Durch das Zusammenwirken der Verzahnung 15 mit der Deckenkante wird hierbei ein Fixieren des Einbaurahmens 2 in der Decke 50 erzielt. Besteht die Decke 50 aus einem verhältnismäßig weichen Material, beispielsweise Rigips, so kann ferner auch ein zusätzlicher Ring eingelegt werden, so dass die Zähne nicht in die Decke einschneiden sondern auf diesen Ring drücken. Anschließend kann dann das Downlight 30 an dem Einbaurahmen 2 befestigt werden, so dass sich letztendlich die in Fig. 6 dargestellte Konfiguration ergibt.When mounting the mounting frame 2 in the opening 51 of a ceiling 50 so it must first be ensured that all locking elements 10 in the in Fig. 1 are shown state, so that the mounting frame 2 can be attached without problems from the bottom to the ceiling 50. Subsequently, the locking elements 10 are pressed to the outside, which, for example, can be done by applying force to the coil spring 15. After exceeding the above breakpoint then snap the locking elements 10 automatically to the outside and take the in Fig. 2 to 5 shown position. By the interaction of the teeth 15 with the Ceiling edge here a fixing of the mounting frame 2 is achieved in the ceiling 50. If the cover 50 is made of a relatively soft material, such as plasterboard, then an additional ring can also be inserted, so that the teeth do not cut into the ceiling but press on this ring. Then, the downlight 30 can be attached to the mounting frame 2, so that ultimately the in Fig. 6 shown configuration results.

Ist eine Demontage des Downlights erwünscht, wird zunächst der Leuchtenkörper von dem Einbaurahmen 2 entfernt. Anschließend werden die Rastelemente 10 wiederum in einen Zustand überführt, in dem eine Entnahme des Einbaurahmens 2 aus der Deckenöffnung 51 ermöglicht ist. Dies kann in einfacher Weise durch Ziehen der Rastelemente 10 an den Spiralfedern 15 zur Innenseite hin erfolgen. Nach Überschreiten des Knickpunkts springen die Flügelarme 12 umgehend wieder in die in Fig. 1 dargestellte Position, die Zähne verlieren ihre haltende Wirkung und der Einbaurahmen 2 kann entfernt werden.If disassembly of the downlight is desired, the lamp body is first removed from the mounting frame 2. Subsequently, the locking elements 10 are again transferred to a state in which a removal of the mounting frame 2 from the ceiling opening 51 is made possible. This can be done in a simple manner by pulling the locking elements 10 on the coil springs 15 to the inside. After exceeding the break point, the wing arms 12 jump back into the in Fig. 1 shown position, the teeth lose their holding effect and the mounting frame 2 can be removed.

Die obige Schilderung verdeutlicht, dass mit Hilfe der erfindungsgemäßen Rastelemente ein besonders einfaches Montieren und Demontieren einer Deckeneinbauleuchte ermöglicht ist. Insbesondere ist hierfür kein Werkzeug erforderlich. Ein weiterer Vorteil besteht dabei darin, dass aufgrund der sich über die gesamte Höhe der Flügelarme 11 erstreckenden Verzahnung 13 automatisch eine Anpassung an die Stärke bzw. Dicke der Decke ergibt. Dies bedeutet, dass die erfindungsgemäße Montagevorrichtung bei verschiedenen Deckenstärken zum Einsatz kommen kann, ohne dass eine spezielle Anpassung aller Komponenten der Vorrichtung erforderlich wäre.The above description makes it clear that with the aid of the latching elements according to the invention a particularly simple mounting and dismounting of a recessed ceiling luminaire is made possible. In particular, no tool is required for this purpose. Another advantage is that due to the over the entire height of the wing arms 11 extending teeth 13 automatically results in an adjustment to the thickness or thickness of the ceiling. This means that the mounting device according to the invention can be used for different ceiling thicknesses, without a special adaptation of all components of the device would be required.
