Description

Die Erfindung betrifft ein Befestigungssystem zur Befestigung von wenigstens einer Leuchteneinheit in einer länglichen, gebogenen Einbauöffnung.The invention relates to a fastening system for fastening at least one lamp unit in an elongated, curved mounting hole.

Ein derartiges Befestigungssystem ist aus der EP 2 243 998 A1 bekannt. Dieses bekannte Befestigungssystem umfasst mehrere Segmente, die im Querschnitt U-förmig gestaltet sind und die in einer Reihe hintereinander angeordnet sind, so dass sie einen Aufnahmebereich für die wenigstens eine Leuchteneinheit bilden. Zwischen den freien Enden der U-Schenkel ist ein Lichtaustrittsbereich zur Abgabe eines von der wenigstens einen Leuchteneinheit abgestrahlten Lichts gebildet. Die Segmente sind untereinander in einem gewissen Maß beweglich, so dass sich das Befestigungssystem insbesondere für einen Einbau in eine insgesamt längliche, gebogene Einbauöffnung eignet. Zur Abdeckung des Lichtaustrittsbereichs ist eine lichtdurchlässige Platte oder alternativ ein lichtdurchlässiges, textiles Gewebe vorgesehen, das zwischen den freien Enden der U-Schenkel mittels Keder-Elementen gespannt gehalten ist. Grundsätzlich lässt sich ein textiles Gewebe leichter in seiner Form der länglichen, gebogenen Einbauöffnung anpassen als eine Platte, die aus einem formstabileren Material besteht.Such a fastening system is known from EP 2 243 998 A1 known. This known fastening system comprises a plurality of segments, which are U-shaped in cross-section and which are arranged in a row one behind the other, so that they form a receiving area for the at least one lighting unit. Between the free ends of the U-legs, a light exit region for emitting a light emitted by the at least one lamp unit light is formed. The segments are mutually movable to a certain extent, so that the fastening system is particularly suitable for installation in an overall elongated, curved mounting hole. To cover the light exit area a translucent plate or alternatively a translucent, textile fabric is provided, which is held taut between the free ends of the U-legs by means of Keder elements. In principle, a textile fabric can be more easily adapted in shape to the oblong, curved installation opening than a plate which consists of a dimensionally stable material.

Im Allgemeinen ist bei einem derartigen Befestigungssystem erwünscht, den Lichtaustrittsbereich so zu gestalten, dass dessen Breite, also die Abmessung quer zu der insgesamt länglichen Erstreckung, möglichst gleichmäßig erscheint. Die Praxis hat gezeigt, dass das menschliche Auge hier bereits sehr kleine Unregelmäßigkeiten in den Breitenabmessungen registriert und diese als störend empfunden werden können. Die Zielstellung einer möglichst gleichmäßigen Breite führt zu einer besonderen Herausforderung bei der Montage des Befestigungssystems in der Einbauöffnung. Bei dem bekannten Befestigungssystem ist zur Montage als eine Möglichkeit vorgesehen, das Befestigungssystem zunächst an wand- bzw. deckenseitig fixierten Schienenelementen zu befestigen und anschließend das Wand- oder Deckenelement zu montieren. Dies erfordert zunächst eine besonders präzise Fixierung der genannten Schienenelemente und eignet sich darüber hinaus nicht in einem Fall, in dem das Befestigungssystem nach Einbau des Wand- oder Deckenelements montiert werden soll.In general, it is desirable in such a fastening system to design the light exit region such that its width, that is to say the dimension transverse to the overall elongated extension, appears as uniform as possible. Practice has shown that the human eye here already very small irregularities in the width dimensions registered and these can be distracting. The goal of a uniform width as possible leads to a special challenge when mounting the mounting system in the mounting hole. In the known fastening system is provided for mounting as a way to attach the fastening system first to wall or ceiling side fixed rail elements and then to mount the wall or ceiling element. This first requires a particularly precise fixation of said rail elements and is also not suitable in a case in which the Mounting system to be installed after installation of the wall or ceiling element.

Gemäß einer Alternative sind zur Halterung in der Einbauöffnung Rast- oder Befestigungselemente vorgesehen, die von der Einbauseite her das Wand- oder Deckenelement kontaktieren. Diese Rast- oder Befestigungselemente sind seitlich an den U-Schenkeln einiger Segmente angebracht. Diese Ausführungsform hat sich allerdings in der Praxis als besonders herstellungsintensiv und aufwändig mit Bezug auf die Montage erwiesen. Zudem ist in diesem Fall eine doppelwandige Ausführung des Wand- oder Deckenelements vorgesehen, wodurch die Gestaltung der Anordnung insgesamt besonders aufwändig ist. Darüber hinaus eignet sich diese Form weniger gut zur Abdeckung des Lichtaustrittsbereichs durch ein gespanntes Gewebe, weil die Fixierung der Segmente vergleichsweise weit weg von den freien Endbereichen der U-Schenkel angreift und Letztere daher tendenziell einen gewissen Bewegungsspielraum aufweisen.According to an alternative, latching or fastening elements are provided for mounting in the installation opening, which contact the wall or ceiling element from the installation side. These locking or fastening elements are mounted laterally on the U-legs of some segments. However, this embodiment has proved in practice to be particularly production-intensive and expensive with respect to the assembly. In addition, a double-walled version of the wall or ceiling element is provided in this case, whereby the overall design of the arrangement is particularly complex. In addition, this form is less suitable for covering the light exit area by a tensioned tissue, because the fixation of the segments comparatively far away from the free end portions of the U-legs attacks and the latter therefore tend to have a certain freedom of movement.

Aus der US 2006/0117685 A1 ist ist ein Formgebungselement bekannt, das sich zur Befestigung einer Leuchteneinheit eignet. Das Formgebungselement weist zwei Flansche zur Aufnahme von Deckenplatten auf.From the US 2006/0117685 A1 is a shaping element is known, which is suitable for mounting a lamp unit. The shaping element has two flanges for receiving ceiling tiles.

The holding element has a flange area as an engagement element for screws for holding the ceiling panels.

Aus der EP 1 912 302 A2 ist eine Einrichtung zum Anschließen von Arbeitsplätzen an ein Energie-, Daten- und/oder Kommunikationsnetz sowie ein Träger- und Montagekanal für eine solche Einrichtung bekannt. Der Träger- und Montagekanal weist ein H-förmiges Querschnittsprofil auf, wobei ein hierdurch gebildeter unterer Teilkanal zur Aufnahme von Einbaugeräten dient. Der Träger- und Montagekanal weist zwei Stützschenkel auf, wobei einer der beiden Stützschenkel zusammen mit einer Klemmleiste zum Anschließen eines Deckenelements dient. Hierbei ist vorgesehen, dass eine Schraube den Stützschenkel durchgreift und mit ihrem Schraubenschaft in einer Gewindebohrung der Klemmleiste festgesetzt ist.From the EP 1 912 302 A2 a device for connecting workstations to a power, data and / or communication network and a carrier and mounting channel for such a device is known. The carrier and mounting channel has an H-shaped cross-sectional profile, wherein a lower sub-channel formed thereby serves for receiving built-in appliances.

Besondere Ausführungsarten der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved according to the invention with the objects mentioned in the independent claims. Particular embodiments of the invention are indicated in the dependent claims.

Gemäß der Erfindung ist ein Befestigungssystem zur Befestigung von wenigstens einer Leuchteneinheit in einer länglichen, gebogenen Einbauöffnung eines Wand- oder Deckenelements, das eine Raumseite von einer Einbauseite trennt, vorgesehen. Das Befestigungssystem weist mehrere, im Querschnitt U-förmige Segmente zur Bildung eines Aufnahmebereichs für die wenigstens eine Leuchteneinheit auf, wobei jedes der Segmente an den beiden freien Enden der beiden betreffenden U-Schenkel jeweils einen mit Bezug auf die U-Form nach außen weisenden Flanschbereich zur raumseitigen Anlage an das Wand- oder Deckenelement aufweist. Der Flanschbereich ist dabei als Angriffselement für ein Verbindungsmittel zur Fixierung des betreffenden Segments an dem Wand- oder Deckenelement ausgestaltet und das Befestigungssystem weist weiterhin ein Profilelement zur einbauseitigen Anlage an das Wand- oder Deckenelement auf, das als Widerlager für das Verbindungsmittel ausgestaltet ist.According to the invention, there is provided a fastening system for fastening at least one lamp unit in an elongate curved mounting opening of a wall or ceiling element which separates a room side from a mounting side. The fastening system has a plurality of, in cross-section U-shaped segments for forming a receiving area for the at least one lamp unit, wherein each of the segments at the two free ends of the two respective U-legs each with respect to the U-shape outwardly facing flange has the room-side contact with the wall or ceiling element. The flange is in this case as engagement element for a connecting means for fixing the relevant Segments configured on the wall or ceiling element and the fastening system further comprises a profile element for installation-side contact with the wall or ceiling element, which is designed as an abutment for the connecting means.

Durch das Profilelement wird erzielt, dass zur Montage des Befestigungssystems an dem Wand- oder Deckenelement kein Rast- oder Befestigungselement seitlich an einem U-Schenkel eines Segments erforderlich ist. Hierdurch ist eine besonders unmittelbare und sichere Fixierung der freien Endbereiche der U-Schenkel am Randbereich der Einbauöffnung ermöglicht. Durch die besonders unmittelbare Fixierung der freien Enden der U-Schenkel lässt sich erzielen, dass die Breite des Lichtaustrittsbereichs besonders gut fixiert werden kann. Auch lässt sich durch eine besonders unmittelbare Fixierung der freien Endbereiche der U-Schenkel erzielen, dass sich das Befestigungssystem besonders gut für eine lichtdurchlässige Abdeckung aus einem Gewebe bzw. einem Textilmaterial eignet, die unter Spannung zwischen den Endbereichen gehaltert ist.By the profile element is achieved that no locking or fastening element is required laterally on a U-leg of a segment for mounting the fastening system to the wall or ceiling element. This allows a particularly immediate and secure fixation of the free end portions of the U-legs at the edge region of the mounting hole. Due to the particularly immediate fixation of the free ends of the U-legs can be achieved that the width of the light exit area can be fixed very well. Also can be achieved by a particularly immediate fixation of the free end portions of the U-legs, that the fastening system is particularly well suited for a translucent cover of a fabric or a textile material, which is supported under tension between the end regions.

Dabei ist durch die Verwendung der Flanschbereiche ermöglicht, dass bei der Herstellung der Einbauöffnung die Toleranzen vergleichsweise groß gewählt werden können.It is possible by the use of the flange that the tolerances can be selected comparatively large in the manufacture of the mounting hole.

Insgesamt lässt sich auf diese Weise der Montagekomfort erhöhen und es lassen sich auch die Herstellungskosten verringern. Ferner eignet sich das Befestigungssystem auch zur Montage an einem lediglich einlagig gestalteten Wand- oder Deckenelement.Overall, can be increased in this way the ease of installation and it can also reduce the cost of production. Furthermore, the fastening system is also suitable for mounting on a single-walled wall or ceiling element.

Vorzugsweise weist das Profilelement im Querschnitt eine L-Form auf, wobei es mit einem der beiden L-Schenkel zur einbauseitigen Anlage an das Wand- oder Deckenelement ausgestaltet ist. Hierdurch ist die Anlage des Profilelements zur Montage am Randbereich der Einbauöffnung erleichtert.Preferably, the profile element has an L-shape in cross section, wherein it is designed with one of the two L-legs for installation-side contact with the wall or ceiling element. As a result, the system of the profile element for mounting on the edge region of the mounting hole is facilitated.

Vorzugsweise weist das Profilelement mehrere Löcher zur Führung des Verbindungsmittels auf, wobei die Löcher in unterschiedlichen Abständen von einem seitlichen Randbereich des Profilelements angeordnet sind. Hierdurch lässt sich erzielen, dass für eine zuverlässige Fixierung des Befestigungssystems in der Einbauöffnung bei der Herstellung der Einbauöffnung die Anforderungen an die Genauigkeit der Breitenabmessung besonders gering gehalten werden können.Preferably, the profile element has a plurality of holes for guiding the connecting means, wherein the holes are arranged at different distances from a lateral edge region of the profile element. This can be achieved that for a reliable fixation of the fastening system in the Installation opening in the manufacture of the mounting hole, the requirements for the accuracy of the width dimension can be kept particularly low.

Erfindungsgemäß weist das Profilelement Einschnitte auf, die derart gestaltet sind, dass durch sie eine Biegung des Profilelements erleichtert ist. Hierdurch lässt sich das Profilelement besonders gut an einen gebogenen Abschnitt des Randbereichs der Einbauöffnung in seiner Form anpassen.According to the invention, the profile element incisions, which are designed such that a bending of the profile element is facilitated by them. As a result, the profile element can be particularly well adapted to a curved portion of the edge region of the mounting hole in its shape.

Vorzugsweise besteht das Profilelement aus Blech besteht, insbesondere aus Weißblech.Preferably, the profile element is made of sheet metal, in particular tinplate.

In Fig. 1 ist eine perspektivische Skizze zu einem Ausführungsbeispiel eines erfindungsgemäßen Befestigungssystems gezeigt, in Fig. 3 ist ein entsprechender Querschnitt skizziert. Das Befestigungssystem ist zur Befestigung wenigstens einer (in den Figuren nicht gezeigten) Leuchteneinheit gestaltet. Bei der Leuchteneinheit kann es sich beispielsweise um eine LED-Lichtquelle mit einer Platine und mehreren darauf angeordneten LEDs handeln.In Fig. 1 is a perspective sketch of an embodiment of a fastening system according to the invention shown in Fig. 3 a corresponding cross-section is sketched. The fastening system is for fastening at least one (in the figures not shown) designed lighting unit. The lighting unit may be, for example, an LED light source with a circuit board and a plurality of LEDs arranged thereon.

Das Befestigungssystem ist zur Befestigung der Leuchteneinheit in einer länglichen, gebogenen Einbauöffnung eines Wand- oder Deckenelements 2 ausgestaltet, das eine Raumseite R von einer Einbauseite E trennt. Die Einbauöffnung kann dabei insgesamt mehrere Meter lang sein und sich gebogen bzw. geschwungen, dabei auch mehrfach und in unterschiedliche Richtungen gekrümmt verlaufend gestaltet sein.The fastening system is designed for fastening the lamp unit in an elongated, curved mounting opening of a wall or ceiling element 2, which separates a room side R from a mounting side E. The mounting hole can be a total of several meters long and bent or curved, while also repeatedly and curved in different directions designed to be running.

Das Befestigungssystem ist dementsprechend derart gestaltet, dass es sich biegen bzw. krümmen lässt, so dass es in seiner Form der Form der Einbauöffnung angepasst wird.The fastening system is accordingly designed such that it can bend or bend, so that it is adapted in its shape to the shape of the mounting hole.

Dementsprechend erstreckt sich auch das Befestigungssystem entlang einer Haupterstreckung L, die entsprechend gekrümmt ist. Beispielsweise können dabei Krümmungsradien von ∞ bis zu ca. 2 Metern vorgesehen sein.Accordingly, the fastening system also extends along a main extension L , which is correspondingly curved. For example, it may be provided radii of curvature of ∞ up to about 2 meters.

Das Befestigungssystem umfasst hierzu mehrere Segmente 3, die in einem Querschnitt normal zu der Haupterstreckung L eine U-Form aufweisen. Dementsprechend weist im Querschnitt betrachtet ein Segment 3 zwei U-Schenkel 6, 6' auf, sowie einen, die beiden U-Schenkel 6, 6' miteinander verbindenden Verbindungsschenkel 6". An einer dem Verbindungsschenkel 6" gegenüberliegenden Seite weisen die U-Schenkel 6, 6' dementsprechend freie Enden 5, 5' auf.The fastening system for this purpose comprises a plurality of segments 3, which have a U-shape in a cross section normal to the main extension L. Correspondingly, viewed in cross-section, a segment 3 has two U-legs 6, 6 ', as well as a connecting leg 6 "connecting the two U-legs 6, 6' to one another.The U-legs 6 are on a side opposite the connecting leg 6" , 6 'accordingly free ends 5, 5'.

Die Segmente 3 können als Spritzgussteile gestaltet sein.The segments 3 can be designed as injection-molded parts.

Zum Einbau ist vorgesehen, dass das Befestigungssystem derart ausgerichtet in die Einbauöffnung eingebaut wird, dass die U-Schenkel 6, 6' mit ihren freien Enden 5,5' zur Raumseite R hin weisen. Eine Abgabe des von der wenigstens einen Leuchteneinheit abgestrahlten Lichts ist zwischen den beiden freien Enden 5, 5' hindurch in den Raum hinein vorgesehen.For installation, it is provided that the fastening system is installed aligned in the mounting hole, that the U-legs 6, 6 'with their free ends 5, 5' facing the room side R out. A delivery of the light emitted by the at least one lamp unit is provided between the two free ends 5, 5 'into the room.

Die Segmente 3 sind vorzugsweise derart ausgerichtet, dass sie zusammen eine Art "Raupe" bilden, wobei sich die Ausrichtung der Segmente 3 kontinuierlich von einem zum nächsten Segment 3 fortsetzt.The segments 3 are preferably aligned such that together they form a kind of "bead", wherein the orientation of the segments 3 continues continuously from one to the next segment 3.

In dem von den U-Schenkeln 6, 6' der Segmente 3 und den Verbindungsschenkeln 6" der Segmente 3 umfassten Raum ist auf diese Weise ein Aufnahmebereich 4 gebildet, der zur Aufnahme der wenigstens einen Leuchteneinheit vorgesehen bzw. ausgestaltet ist.In the area covered by the U-legs 6, 6 'of the segments 3 and the connecting legs 6 "of the segments 3, a receiving area 4 is formed in this way, which is provided or configured to receive the at least one lighting unit.

Jedes Segment 3 weist an seinen beiden freien Enden 5, 5' der beiden betreffenden U-Schenkel 6, 6' jeweils einen, mit Bezug auf die U-Form nach außen weisenden Flanschbereich 7, 7' auf, der zur raumseitigen Anlage an das Wand- oder Deckenelement 2 vorgesehen ist.Each segment 3 has at its two free ends 5, 5 'of the two respective U-legs 6, 6' in each case one, with respect to the U-shape outwardly facing flange portion 7, 7 ', for the room-side contact with the wall - Is provided or ceiling element 2.

Der Flanschbereich 7, 7' ist dabei als Angriffselement für ein Verbindungsmittel V, insbesondere eine Schraube, zur Fixierung des betreffenden Segments 3 an dem Wand- oder Deckenelement 2 ausgestaltet. Beispielsweise kann der Flanschbereich 7, 7' hierfür wenigstens ein Durchführungsloch 71 aufweisen, das zur Durchführung des Verbindungsmittels V ausgestaltet ist. Beispielsweise kann es sich hierbei um ein Senkloch, insbesondere für eine Senkkopfschraube handeln.The flange portion 7, 7 'is configured as a engagement element for a connecting means V , in particular a screw, for fixing the relevant segment 3 to the wall or ceiling element 2. For example, the flange region 7, 7 'for this purpose have at least one feedthrough hole 71, which is designed to pass through the connection means V. For example, this may be a countersunk hole, in particular for a countersunk screw.

Vorzugsweise ist vorgesehen, dass der Flanschbereich 7, 7' wenigstens zwei, beispielsweise wenigstens drei entsprechende Durchführungslöcher 71 aufweist.It is preferably provided that the flange region 7, 7 'has at least two, for example at least three, corresponding through holes 71.

Weiterhin umfasst das Befestigungssystem ein Profilelement 8, das zur einbauseitigen Anlage an das Wand- oder Deckenelement 2 vorgesehen und dabei als Widerlager für das Verbindungsmittel V ausgestaltet ist. In Fig. 4 ist ein Abschnitt des Profilelements 8 perspektivisch skizziert. Zum Einbau kann vorgesehen sein, dass in einem ersten Schritt das Profilelement 8 wie vorgesehen mit seiner Hauptachse entlang eines Randbereichs der Einbauöffnung angeordnet, insbesondere fixiert wird und in einem weiteren, Schritt die Segmente 3 in ihre vorgesehene Position gebracht werden und schließlich das Verbindungselement V angebracht wird. Zur Fixierung muss das Profilelement 8 lediglich an einigen Stellen bzw. partiell fixiert werden.Furthermore, the fastening system comprises a profile element 8, which is provided for installation-side contact with the wall or ceiling element 2 and is designed as an abutment for the connecting means V. In Fig. 4 a section of the profile element 8 is sketched in perspective. For installation, it may be provided that, in a first step, the profile element 8 is arranged with its main axis along an edge region of the installation opening, in particular fixed and in a further step, the segments 3 are brought into their intended position and finally the connecting element V attached becomes. To fix the profile element 8 only in some places or partially fixed.

Auf diese Weise lässt sich bewirken, dass sich der Flanschbereich 7, 7', der sich unmittelbar am freien Ende 5, 5' des betreffenden U-Schenkels 6, 6' befindet, von der Raumseite R her fest und zuverlässig am Randbereich der Einbauöffnung fixieren lässt.In this way, it is possible to ensure that the flange area 7, 7 ', which is located directly at the free end 5, 5' of the respective U-leg 6, 6 ', fixes firmly and reliably on the edge area of the installation opening from the room side R forth leaves.

Dementsprechend ist die Gestaltung des Befestigungssystems vorzugsweise derart, dass das Profilelement 8 zu den Segmenten 3 keine strukturelle Verbindung hat, solange das Befestigungssystem nicht in die Einbauöffnung eingebaut ist. In diesem Sinne stellt das Profilelement 8 also ein separates Bauteil dar, das unabhängig von dem restlichen Befestigungssystem gehandhabt werden kann.Accordingly, the design of the fastening system is preferably such that the profile element 8 to the segments 3 has no structural connection, as long as the fastening system is not installed in the mounting hole. In this sense, the profile element 8 thus represents a separate component that can be handled independently of the rest of the fastening system.

Vorteilhaft ist das Profilelement 8 so lang gestaltet, dass es sich im eingebauten Zustand - entlang der Haupterstreckung L betrachtet - über mehrere benachbarte Flanschbereiche 7 hin erstreckt und dabei für alle diese Flanschbereiche 7 analog als Widerlager gestaltet ist. Hierdurch ist die Anzahl der Bauteile insgesamt reduziert und die Montage weiterhin erleichtert.Advantageously, the profile element 8 is designed so long that it extends in the installed state - viewed along the main extension L - over several adjacent flange portions 7 and is designed for all these flange portions 7 analogous as an abutment. As a result, the number of components is reduced overall and the assembly continues to facilitate.

Vorzugsweise weist das Profilelement 8 im Querschnitt eine L-Form auf, so dass es zwei Schenkel 81, 82 umfasst. Einer der beiden Schenkel - im gezeigten Beispiel der mit 81 bezeichnete Schenkel - ist dabei zur einbauseitigen Anlage an das Wand- oder Deckenelement 2 ausgestaltet. Der andere Schenkel 82 kann zur Anlage an einen zum Zentrum der Einbauöffnung hin weisenden Randbereich der Einbauöffnung vorgesehen sein. Vorzugsweise ist im Querschnitt betrachtet der zur einbauseitigen Anlage an das Wand- oder Deckenelement 2 ausgestalte Schenkel 81 breiter als der andere Schenkel 82.Preferably, the profile element 8 has an L-shape in cross section, so that it comprises two legs 81, 82. One of the two legs - in the example shown, the leg designated by 81 - is configured for installation on the wall or ceiling element 2. The other leg 82 may be provided for abutment with an edge region of the installation opening facing towards the center of the installation opening. Preferably, viewed in cross-section, the leg 81 designed for installation on the wall or ceiling element 2 is wider than the other leg 82.

Um das Profilelement 8 besonders gut so biegen zu können, dass es sich dem Verlauf der Einbauöffnung anpasst, weist es vorzugsweise Einschnitte 86, 87 auf, insbesondere seitliche Einschnitte. Die Einschnitte 86, 87 sind vorzugsweise an beiden Schenkeln 81, 82 ausgebildet, insbesondere dabei jeweils zueinander versetzt, so wie in Fig. 4 beispielhaft gezeigt.To be able to bend the profile element 8 so well that it adapts to the course of the installation opening, it preferably has notches 86, 87, in particular lateral incisions. The notches 86, 87 are preferably formed on both legs 81, 82, in particular each offset from each other, as in Fig. 4 shown by way of example.

Wie weiterhin in Fig. 4 beispielhaft gezeigt, weist das Profilelement 8 vorzugsweise mehrere Löcher 85 auf, die zur Führung des Verbindungsmittels V bei der Montage vorgesehen sind. Dabei sind die Löcher 85 vorzugsweise in unterschiedlichen Abständen von einem seitlichen Randbereich 83 ausgebildet, insbesondere in unterschiedlichen Abständen zu einem Randbereich parallel zu der Hauptachse des Profilelements 8. Die Löcher 85 sind dementsprechend zweckmäßig in demjenigen Schenkel 81 ausgebildet, der zur einbauseitigen Anlage an das Wand- oder Deckenelement 2 ausgestaltet ist.As continues in Fig. 4 shown by way of example, the profile element 8 preferably has a plurality of holes 85 which are used to guide the connecting means V during assembly are provided. The holes 85 are preferably formed at different distances from a lateral edge region 83, in particular at different distances to an edge region parallel to the main axis of the profile element 8. The holes 85 are accordingly suitably formed in that leg 81, which for installation-side contact with the wall - Is or ceiling element 2 is configured.

Vorzugsweise sind die Löcher 85 mit einheitlichem Durchmesser und dabei mit geringen gegenseitigen Abständen ausgebildet. Beispielsweise kann vorgesehen sein, dass die Löcher 85 gruppenweise ausgebildet sind und innerhalb einer Gruppe der gegenseitige Abstand zwischen den Löchern 85 maximal doppelt so groß ist wie der Durchmesser der Löcher 85, vorzugsweise maximal dem Durchmesser der Löcher 85 entspricht. Hierdurch lässt sich erzielen, dass die Genauigkeit bei der Fixierung des Profilelements 8 reduziert werden kann und dennoch ein zuverlässiges Widerlager für das Verbindungsmittel V gebildet ist; eine entsprechende Schraube zieht sich hierbei beim Einschrauben selbstzentrierend in eines der Löcher 85. Bei dem in Fig. 4 skizzierten Beispiel sind die Löcher 85 in Gruppen zu jeweils 149 Löchern zusammengefasst. Zwischen den Gruppen ist lediglich jeweils einer der Einschnitte 86 ausgebildet.Preferably, the holes 85 are of uniform diameter and thereby formed with small mutual distances. For example, it may be provided that the holes 85 are formed in groups and within a group of the mutual distance between the holes 85 is at most twice as large as the diameter of the holes 85, preferably at most equal to the diameter of the holes 85. This makes it possible to achieve that the accuracy in fixing the profile element 8 can be reduced and yet a reliable abutment for the connecting means V is formed; a corresponding screw is tightened when screwing self-centering in one of the holes 85. In the in Fig. 4 sketched example, the holes 85 are grouped in groups of 149 holes. Only one of the incisions 86 is formed between the groups.

Das Profilelement 8 besteht vorzugsweise aus Blech, insbesondere aus Weißblech.The profile element 8 is preferably made of sheet metal, in particular tinplate.

Weiterhin vorzugsweise weist jedes der Segmente 3 ein, insbesondere stegförmiges Aussteifungselement 9 auf, das zwischen den beiden betreffenden U-Schenkeln 6, 6' angeordnet ist. Vorteilhaft ist das Aussteifungselement 9 ein Bestandteil des Segments 3, das bei der Herstellung des Segments 3 mitgespritzt wird. Bei der Montage werden die beiden U-Schenkel 6, 6' durch das Aussteifungselement 9 in einem bestimmten, definierten Abstand gehalten, so dass sich das Befestigungssystem besonders einfach so in der Einbauöffnung fixieren lässt, dass es eine besonders geleichmäßige Breite aufweist.Further preferably, each of the segments 3, in particular web-shaped stiffening element 9, which is disposed between the two respective U-legs 6, 6 '. Advantageously, the stiffening element 9 is a part of the segment 3, which is injected in the production of the segment 3. During assembly, the two U-legs 6, 6 'are held by the stiffening element 9 at a specific, defined distance, so that the fastening system can be particularly easily fixed in the installation opening such that it has a particularly uniform width.

Wenn das Aussteifungselement 9 an seinen beiden Kontaktstellen zu den U-Schenkeln 6, 6'jeweils eine Sollbruchstelle 91, 92 aufweist, lässt es sich nach Einbau des Befestigungssystems durch einfaches Herausbrechen besonders leicht lösen.If the stiffening element 9 at its two contact points to the U-legs 6, 6 'each have a predetermined breaking point 91, 92, it can be particularly easy to solve after installation of the fastening system by simply breaking out.

Weiterhin weist das Befestigungssystem vorteilhaft ein Keder-Halteprofil 10 zur Halterung eines Keders 11 an wenigstens einem der beiden freien Enden 5, 5' der beiden betreffenden U-Schenkel 6, 6' auf. Vorzugsweise ist an beiden freien Enden 5, 5'jeweils ein derartiges Keder-Halteprofil 10 angeordnet. Das Keder-Halteprofil 10 ist vorzugweise so lang gestaltet, dass es sich in Haupterstreckung L betrachtet über mehrere Segmente 3 hin erstreckt.Furthermore, the fastening system advantageously has a piping holding profile 10 for holding a welt 11 on at least one of the two free ends 5, 5 'of the two respective U-legs 6, 6'. Preferably, such a piping holding profile 10 is arranged at both free ends 5, 5 '. The piping holding profile 10 is preferably designed so long that, viewed in the main extension L , it extends over a plurality of segments 3.

Wie in den Figuren beispielhaft skizziert, dient der Keder 11 dabei zur Halterung einer lichtdurchlässigen Abdeckung 15, die als Lichtaustrittselement zwischen den beiden freien Enden 5,5' gespannt gehalten ist. Die Abdeckung 15 kann beispielsweise aus einem flexiblen Kunststoff bestehen, beispielsweise kann die Abdeckung 15 durch eine PVC-Folie gebildet sein, welche einerseits die gewünschten optischen Eigenschaften aufweist und andererseits die mit Bezug auf die Krümmung der Einbauöffnung erforderliche Flexibilität. Der Keder 11 kann beispielsweise aus Silikon bestehen. Der Keder 11 kann mit der Abdeckung 15 durch Vernähen verbunden sein.As sketched by way of example in the figures, the piping 11 serves to hold a translucent cover 15, which is held taut as a light exit element between the two free ends 5, 5 '. The cover 15 may for example consist of a flexible plastic, for example, the cover 15 may be formed by a PVC film which on the one hand has the desired optical properties and on the other hand required with respect to the curvature of the mounting hole flexibility. The piping 11 may for example consist of silicone. The piping 11 may be connected to the cover 15 by sewing.

Zur Halterung des Keder-Halteprofils 10 ist vorteilhaft an dem Segment 3 an dem betreffenden freien Ende 5, 5' eine Aufnahmenut 12 ausgebildet, insbesondere zur rastenden Halterung des Keder-Halteprofils 10. Im gezeigten Ausführungsbeispiel weist das Befestigungssystem hierzu eine Rastverbindung 13 auf, die zur rastenden Halterung des Keder-Halteprofils 10 in der Aufnahmenut 12 gestaltet ist. Beispielsweise kann die Rastverbindung hierzu einen am freien Endbereich ausgebildeten Widerhaken umfassen, der in eine entsprechende Ausnehmung am Keder-Halteprofil 10 eingreift. Die Ausgestaltung kann dafür vorgesehen sein, dass das Keder-Halteprofil 10 nach Anbringung in der Aufnahmenut 12 nicht mehr entfernt wird.For holding the piping holding profile 10 is advantageously formed on the segment 3 at the relevant free end 5, 5 'a receiving groove 12, in particular for latching support of the piping holding profile 10. In the illustrated embodiment, the fastening system for this purpose a latching connection 13 which designed for latching mounting of the piping holding profile 10 in the receiving groove 12. For example, the latching connection for this purpose comprise a barb formed on the free end region, which engages in a corresponding recess on the piping holding profile 10. The configuration can be provided that the piping-retaining profile 10 is no longer removed after mounting in the receiving groove 12.

Falls erwünscht ist, das Befestigungssystem gemäß einer Variante ohne die Flanschbereiche 7, 7' herstellen zu können, also beispielsweise als Anbau- oder Pendelvariante, so kann vorgesehen sein, dass ein Spritzgusswerk zur Herstellung der Segmente 3 an den betreffenden Stellen einen Einschub aufweist, jedoch die Aufnahmenut 12 für das Keder-Halteprofil 10 enthält.If it is desired to be able to produce the fastening system according to a variant without the flange regions 7, 7 ', thus for example as an attachment or pendulum variant, then it can be provided that an injection molding plant for the production of the segments 3 has an insert at the relevant points, however the receiving groove 12 for the piping holding profile 10 contains.

Das Keder-Halteprofil 10 kann beispielsweise aus Kunststoff bestehen, insbesondere aus einem schlagzähen, flexiblen Kunststoff, beispielsweise aus PC.The piping holding profile 10 may for example consist of plastic, in particular of an impact resistant, flexible plastic, such as PC.

Das Keder-Halteprofil 10 kann noch eine zur Raumseite R hin weisende Spachtelkante 14 aufweisen. Hierdurch lässt sich nach Montage des Befestigungssystems der Randbereich der Einbauöffnung raumseitig besonders gut verspachteln; es lässt sich also besonders gut ein deckenbündiges Finish erzielen. Die Spachtelkante 14 kann beispielweise eine Breite zwischen 1 mm und 3 mm aufweisen, insbesondere eine Breite von etwa 2 mm.The piping holding profile 10 may still have a spatula edge 14 pointing toward the room side R. As a result, the edge region of the installation opening on the room side can be spatulated particularly well on the room side after installation of the fastening system; it is therefore very easy to achieve a ceiling-flush finish. The spatula edge 14 may for example have a width between 1 mm and 3 mm, in particular a width of about 2 mm.

Das erfindungsgemäße Befestigungssystem bietet im Vergleich zu einer konventionellen Rigips-Spanndecken-Lösung insbesondere mit Bezug auf die Montage einen erheblichen Zeitvorteil und verbesserten Komfort. Zudem ermöglicht es ein reduzierteres Finish.The fastening system according to the invention offers in comparison to a conventional Rigips-Stretch ceiling solution, in particular with respect to the assembly a considerable time advantage and improved comfort. It also allows for a reduced finish.
