Description

Leuchtenraster Luminaire grid
Die Erfindung betrifft einen Leuchtenraster mit gekrümmten Außenreflektoren und quer dazu verlaufenden Querlamellen mit etwa V-förmigem Querschnitt, von denen jede durch entspre¬ chende Ausschnitte in den Außenreflektoren g-esteckt ist, wo¬ bei die Wandungen der Querlamelle an der Oberseite Anschlag¬ kanten aufweisen, welche an der Innenseite der Außenreflek¬ toren anliegen.The invention relates to a luminaire grid with curved outer reflectors and transverse lamellae with an approximately V-shaped cross section, each of which is inserted through corresponding cutouts in the outer reflectors, the walls of the transverse lamella having stop edges on the upper side , which rest on the inside of the outer reflectors.
Ein derartiges Leuchtenraster ist bereits aus der DE 30 05 762 bekannt. Bei diesem bekannten Leuchtenraster ist die Quer¬ lamelle an der Unterseite mit einem Querschlitz versehen, wobei zur Befestigung der Querlamelle an dem Außenreflektor die Unterkante jedes Ausschnittes der Außenreflektoren in einen Querschlitz einer Querlamelle steckt.Such a luminaire grid is already known from DE 30 05 762. In this known luminaire grid, the transverse lamella is provided with a transverse slot on the underside, the lower edge of each cutout of the external reflectors being inserted into a transverse slot of a transverse lamella for fastening the transverse lamella to the outer reflector.
Bei diesem Leuchtenraster mußte somit die Querlamelle in den Außenreflektor in Form einer Kreisbewegung eingehängt werden, um beide Teile lagenrichtig zueinander zu montieren, d. h. die Querlamelle zum Einrasten in den Außenreflektor zu bringen. Hierzu wurde der Querschlitz der Querlamelle zunächst in den Ausschnitt des Außenreflektors eingeführt und dann wurde mit einer Kreisbogenbewegung die Querlamelle auf den Außenreflek¬ tor eingeschwenkt, wobei am Außenreflektor noch Vorsprünge vorgesehen waren, welche in zugeordnete Sperrschlitze an den Querlamellen einrasteten.With this luminaire grid, the cross lamella had to be hung in the outer reflector in the form of a circular movement in order to mount the two parts in the correct position, i.e. H. to bring the cross lamella into the outer reflector. For this purpose, the transverse slit of the transverse lamella was first inserted into the cutout of the outer reflector and then the transverse lamella was pivoted onto the outer reflector with a circular arc movement, projections were also provided on the outer reflector, which latched into assigned locking slots on the transverse lamellae.
Die Montage der Querlamellen an den zugeordneten Außenreflek¬ toren konnte somit nur in aufwendiger Art geschehen, was nicht maschinell durchgeführt werden konnte. Der vorliegenden Erfindung liegt deshalb die Aufgabe zu¬ grunde, eine Befestigung zwischen einer Querlamelle und einem Außenreflektor eines Leuchtenrasters zu erwirken, die in einfacher Weise maschinell vorgenommen werden kann.The assembly of the transverse slats on the assigned external reflectors could therefore only be done in a complex manner, which could not be carried out mechanically. The present invention is therefore based on the object of achieving a fastening between a transverse lamella and an external reflector of a luminaire grid, which can be carried out mechanically in a simple manner.
Zur Lösung der gestellten Aufgabe ist die Erfindung dadurch gekennzeichnet, daß an der Unterseite der Querlamelle eine in den Außenreflektor einfahrbare gerade Nase als Anschlag¬ kante ausgebildet ist, und daß jede Wandung der Querlamelle einen nach außen weisenden Absatz aufweist, welcher den Ausschnitt in dem Außenreflektor durchgreift und rastend an der Außenseite des Außenreflektors anliegt.To achieve the object, the invention is characterized in that a straight nose retractable into the outer reflector is formed as a stop edge on the underside of the transverse lamella, and that each wall of the transverse lamella has an outwardly pointing shoulder, which has the cutout in the outer reflector reaches through and clicks against the outside of the outer reflector.
Bei dem Leuchtenraster nach der Erfindung ist demnach an der Oberseite der Querlamelle eine Anschlagkante vorge¬ sehen und weiterhin erfindungsgemäß an der Unterseite der Querlamelle eine gerade Nase ebenfalls als Anschlagkante ausgebildet, wobei die Querlamelle in einfacher Gerad¬ führung in den Ausschnitt eines Außenreflektors einge¬ fahren werden kann und dann die Absätze an den Querlamellen an der Außenseite des Außenreflektors verrasten.In the luminaire grid according to the invention, a stop edge is accordingly provided on the upper side of the transverse lamella and, furthermore, according to the invention, a straight nose is also formed as a stop edge on the underside of the transverse lamella, the transverse lamella being inserted in a straight line into the cutout of an external reflector can and then lock the paragraphs on the cross blades on the outside of the outer reflector.
Mit der beschriebenen, neuartigen Befestigung ergibt sich nun erstmals die Möglichkeit, daß man mit der Querlamelle in Richtung ihrer Längsachse gerade in den Ausschnitt des senkrecht hierzu stehenden Außenreflektors einfahren kann, wodurch es zu einer selbsttätigen Verrastung der Quer¬ lamelle im Ausschnitt des Außenreflektors kommt. Eine Schwenkbewegung wie sie sonst zum Einführen der Quer¬ lamelle bei einem bekannten Leuchtenraster nötig ist, kann nun nach der Erfindung entfallen. Damit ist eine einfache maschinelle Montage derartiger Querlamellen in zugeordneten Außenreflektoren möglich. Das Anbringen von derartigen Absätzen ist besonders ein¬ fach und ebenfalls können in einfacher Art die Nase bzw. die Anschlagkanten ausgestanzt werden, wodurch sich, ohne aufwendige Verformungen, ein billiges Einschubteil ergibt. Ein derartiger Absatz kann durch Abkantung des Materials der Querlamelle unter Bildung eines auswärts verformten, aus der Ebene der Querlamelle herausspringenden* Kante her¬ gestellt werden. Ebenso ist es möglich, diesen Absatz unter Formung einer Sicke herzustellen.With the described, novel fastening, it is now possible for the first time that the transverse lamella can be moved in the direction of its longitudinal axis into the cutout of the outer reflector perpendicular to it, which results in the transverse lamella automatically locking in the cutout of the outer reflector. According to the invention, a pivoting movement, as is otherwise necessary for inserting the transverse lamella in a known luminaire grid, can now be dispensed with. This enables simple mechanical assembly of such transverse lamellae in assigned external reflectors. The attachment of such heels is particularly simple and the nose or the stop edges can also be punched out in a simple manner, which results in an inexpensive insert part without complex deformations. Such a shoulder can be produced by bending the material of the transverse lamella to form an outwardly deformed * edge which protrudes from the plane of the transverse lamella. It is also possible to produce this paragraph by forming a bead.
In bevorzugter Ausgestaltung ist es vorgesehen, daß die stirnseitigen Kanten der Querlamelle nach Art von Keil¬ flächen in Längsrichtung der Querlamelle nach innen konisch abgebogen ausgebildet sind.In a preferred embodiment it is provided that the front edges of the transverse lamella are conically bent inwards in the longitudinal direction of the transverse lamella in the manner of wedge surfaces.
Das Zubiegen der stirnseitigen Kanten der Querlamelle läßt sich in einfacher Art bewerkstelligen, wobei sich in Ver¬ bindung mit den konisch verlaufenden Keilflächen ein ein¬ faches zentrisches Einfahren in den Ausschnitt des Außen¬ reflektors ergibt.The bending of the front edges of the transverse lamella can be accomplished in a simple manner, and in connection with the conical wedge surfaces there is a simple centric entry into the cutout of the outer reflector.
In weiterer vorteilhafter Ausgestaltung weist die Nase in Einfuhrrichtung schräg verlaufende Kanten auf, die zum einen der Außenkontur des Außenreflektors entsprechen und zum anderen senkrecht zum Querschnitt des Außenreflek¬ tors gerichtet sind. Damit legt sich die Nase formschlüssig an der einen Seite des Außenreflektors an.In a further advantageous embodiment, the nose has inclined edges in the direction of insertion, which on the one hand correspond to the outer contour of the outer reflector and on the other hand are directed perpendicular to the cross section of the outer reflector. So the nose fits positively on one side of the outer reflector.
In dieser Art werden im Bereich der Nase Einlaufkanten geschaffen, welche nach dem Einfahren die Querlamelle an der Unterseite im Bereich des Ausschnittes des Außen¬ reflektors sichern. Im folgenden wird die Erfindung anhand von lediglich einen Ausführungsweg darstellende Zeichnungen näher erläutert. Hierbei gehen aus den Zeichnungen und ihrer Beschreibung weitere erfindungswesentliche Merkmale und Vorteile der Erfindung hervor.In this way, inlet edges are created in the area of the nose, which secure the transverse lamella on the underside in the area of the cutout of the outer reflector after the retraction. The invention is explained in more detail below with the aid of drawings which illustrate only one embodiment. Here, from the drawings and their description, further features and advantages of the invention that are essential to the invention emerge.
Der Erfindungsgegenstand der vorliegenden Erfindung ergibt sich nicht nur aus dem Gegenstand der einzelnen Patentan¬ sprüche, sondern auch aus der Kombination der einzelnen Patentansprüche untereinander.The subject matter of the present invention results not only from the subject matter of the individual patent claims, but also from the combination of the individual patent claims with one another.

In Fig. 1 ist ein Außenreflektor 2 dargestellt mit einem Ausschnitt 3 nach Fig. 3, in welchen eine Querlamelle 1 eingeschoben ist. Nach Fig. 1 ist erkennbar, daß an der Unterseite der Quer¬ lamelle 1 eine in den Außenreflektor 2 einfahrbare gerade Nase 8 als Anschlagkante ausgebildet ist, und daß die Wandungen 4, 5 nach Fig. 2 der Querlamelle 1 nach außen weisende Absätze 9 aufweisen, welche den Ausschnitt 3 nach Fig. 3 in dem Außenreflektor 2 durchgreifen und hier¬ bei rastend über ihre gesamte Länge an der Außenseite 10 des Außenreflektors 2 anliegen.In Fig. 1, an outer reflector 2 is shown with a section 3 of FIG. 3, in which a transverse lamella 1 is inserted. Of FIG. 1 it is seen that a retractable at the bottom of Q uer¬ lamella 1 in the outer reflector 2 straight nose 8 is formed as a stop edge, and that the walls 4, 5 of Fig. 2, the cross lamella 1 outwardly facing paragraphs 9 3 which pass through the cutout 3 according to FIG. 3 in the outer reflector 2 and rest here on the outer side 10 of the outer reflector 2 in a latching manner over their entire length.
An der Oberseite der Querlamelle 1 ist - wie auch aus Fig. 2 ersichtlich - eine Anschlagkante 6 ausgebildet, welche an der Innenseite 7 des Außenreflektors 2 anliegt.On the upper side of the transverse lamella 1, as can also be seen from FIG. 2, a stop edge 6 is formed which bears on the inside 7 of the outer reflector 2.
Die Nase 8 nach den Fig. 1 und 2 entsteht in Verbindung mit Kanten 12 und 13 durch Abbiegen der Querlamelle 1 nach Fig. 4 entlang der Biegelinie 20.The nose 8 according to FIGS. 1 and 2 arises in connection with edges 12 and 13 by bending the transverse lamella 1 according to FIG. 4 along the bending line 20.
Die Nase 8 bildet hierbei in Einfuhrrichtung schräg ver¬ laufende Kanten 12, 13 - insbesondere nach Fig. 1 er¬ sichtlich - die zum einen hier die Kante 13 der Außen¬ kontur des Außeπreflektors 2 entsprechen und zum anderen hier die Kante 12 senkrecht zum Querschnitt des Außen¬ reflektors 2 gerichtet sind.The nose 8 here forms edges 12, 13 which run obliquely in the direction of insertion - in particular according to FIG. 1 - which here correspond on the one hand to the edge 13 of the outer contour of the outer reflector 2 and on the other hand here the edge 12 perpendicular to the cross section of the external reflector 2 are directed.
Bei der Montage der Querlamelle 1 im Bereich des Aus¬ schnittes 3 des Außenreflektors 2 fährt die Nase 8 in gerader Richtung an die Unterkante 19 des Ausschnittes 3 nach Fig. 3, während die Anschlagkante 6 an der Innen¬ seite 7 des Außenreflektors 2 zum Anliegen kommt.When installing the transverse lamella 1 in the region of the cutout 3 of the outer reflector 2, the nose 8 moves in a straight direction to the lower edge 19 of the cutout 3 according to FIG. 3, while the stop edge 6 bears against the inner side 7 of the outer reflector 2 is coming.
Nach Fig. 4 sind Absätze 9 ersichtlich, die vorzugsweise durch Abkaπtung des Materials erzeugt werden, wobei durch Abbiegen entlang der Biegelinie 20 nach Fig. 4 ein V-förmiger Querschnitt der Querlamelle geschaffen wird mit seitlichen über die Flächen der Wandungen 4, 5 nach außen weisenden Absätzen 9. Im weiteren werden auch die stirnseitigen Kanten 11 nach Fig. 4 der Querlamelle 1 nach Art von Keilflächen in Längs¬ richtung der Querlamelle nach innen konisch abgebogen, wo¬ durch nach Fig. 2 die Keilflächen 17 entstehen. Über diese Keilflächen 17 läßt sich die Querlamelle 1 besonders leicht in den Ausschnitt 3 nach Fig. 3 einschieben, wobei die Ab¬ sätze 9 den Ausschnitt 3 durchfahren und anschließend an der Außenseite 10 des Außeπreflektors 2 nach Fig. 1 rastend anliegen. Mit dieser Ausbildung wird eine linienförmige konturengerechte Anlage der Querlamelle 1 an dem Außen¬ reflektor 2 gewährleistet.4, paragraphs 9 can be seen, which are preferably produced by folding the material, whereby by bending along the bending line 20 according to FIG. 4, a V-shaped cross section of the transverse lamella is created with lateral over the surfaces of the walls 4, 5 to the outside indicative paragraphs 9. Furthermore, the front edges 11 of FIG. 4 of the transverse lamella 1 are conically bent inwards in the manner of wedge surfaces in the longitudinal direction of the transverse lamella, as a result of which the wedge surfaces 17 are formed according to FIG. 2. The transverse lamella 1 can be pushed particularly easily into the cutout 3 according to FIG. 3 via these wedge surfaces 17, the paragraphs 9 passing through the cutout 3 and then resting against the outside 10 of the outer reflector 2 according to FIG. 1. With this design, a linear contour-conforming contact of the transverse lamella 1 on the outer reflector 2 is ensured.
Die Anschlagkaπte 6 und die Nase 8 halten hierbei in Gegen¬ richtung zu den Absätzen 9 die Querlamelle an der Innen¬ seite 7 des Außenreflektors 2 fest.The stop edge 6 and the nose 8 hold the transverse lamella on the inner side 7 of the outer reflector 2 in the opposite direction to the shoulders 9.
Nach Fig. 1 ist ersichtlich, daß in Verbindung mit den Keilflächen 17 nach Fig. 2 die Kante 13 und die Einlauf¬ schräge 14 das Einfahren der Querlamelle 1 in den Aus¬ schnitt 3 erleichtern.According to FIG. 1, it can be seen that in connection with the wedge surfaces 17 according to FIG. 2, the edge 13 and the inlet slope 14 facilitate the insertion of the transverse lamella 1 into the cutout 3.
Zusätzlich sind an der Stirnseite der Querlamelle 1 im Be¬ reich der Keilflächen 17 noch eine Abschrägung 16 ausge¬ bildet, so wie eine Anlaufkante 18, wodurch auch bei einem etwa versehentlich schräg Ansetzen der Querlamelle an dem Ausschnitt die Querlamelle leicht in den Ausschnitt 3 ein¬ geschoben werden kann.In addition, a bevel 16 is also formed on the end face of the transverse lamella 1 in the area of the wedge surfaces 17, as is a leading edge 18, so that the transverse lamella easily slides into the cutout 3 even if the transverse lamella is accidentally placed obliquely on the cutout ¬ can be pushed.
Aus Fig. 1 in Verbindung mit Fig. 2 wird demnach ersichtlich, daß, um das Einführen der Querlamelle in den Ausschnitt 3 zu erleichtern, und um die Querlamelle sicher zu halten, Keilflächen 17 mit nach innen weisenden konischen Abbie- gungen vorgesehen sind, wobei die Keilflächen 17 selbst eine Abschrägung 16 aufweisen sowie eine Anlaufkante 15. In Verbindung mit der Anschlagkante 6, welche eine Einlauf¬ schräge 14 aufweist, sowie mit der Nase 8, welche eine schräg verlaufende Einlaufkante 13 aufweist, kann somit die Querlamelle in einfacher Art mit einer einfachen Einschubbewegung ohne weiteres Schwenken in den Ausschnitt 3 eingefahren werden.From FIG. 1 in conjunction with FIG. 2 it can thus be seen that in order to facilitate the insertion of the transverse lamella into the cutout 3 and to hold the transverse lamella securely, wedge surfaces 17 are provided with conical bends pointing inwards, whereby the wedge surfaces 17 themselves have a bevel 16 and a leading edge 15. In connection with the stop edge 6, which has an inlet bevel 14, and with the nose 8, which a has inclined leading edge 13, the transverse lamella can thus be retracted into the cutout 3 in a simple manner with a simple insertion movement without further pivoting.
Aus Fig. 3 ist weiterhin ersichtlich, daß an der Ober¬ seite des Ausschnittes 3 Führungen 18 ausgebildet sind, um in Verbindung mit der Anschlagkante 6 an den Wandungen 4, 5 der Querlamelle 1 eine gewisse Zentrierung zu er¬ reichen. 3 that guides 3 are formed on the upper side of the cutout in order to achieve a certain centering in connection with the stop edge 6 on the walls 4, 5 of the transverse lamella 1.
