Description

Die Erfindung betrifft eine Befestigungsanordnung für untereinander angeordnete Lamellen einer Jalousie an einer Fassaden-Tragkonstruktion mit senkrecht zur Längsrichtung der Lamellen verlaufenden, als Schiene ausgebildeten Tragprofilen mit einer sich in Profillängsrichtung erstreckenden Nut, in die die Lamellen an mindestens zwei Stellen haltende Konsolen eingeschoben sind, die jeweils einen an dem Tragprofil anliegenden Schenkel und einen von dem Tragprofil winkelig abstehenden Schenkel aufweisen und mit Ansätzen an dem am Tragprofil anliegenden Schenkel in Ausnehmungen der Tragprofile gehalten sind.The invention relates to a fastening arrangement for mutually arranged slats of a blind on a facade support structure with perpendicular to the longitudinal direction of the slats, designed as a rail support profile with a groove extending in the longitudinal direction of the profile, into which the slats are inserted at at least two points holding brackets each have a leg resting on the support profile and a leg projecting at an angle from the support profile and are held with recesses on the leg resting on the support profile in recesses of the support profiles.

Eine derartige Ausführungsform läßt sich der DE-A-29 10877 entnehmen. Diese Vorveröffentlichung offenbart verschiedene Ausführungsformen für Ventilationsgitter. Die Tragprofile können Aluminiumprofile sein, die eine im Querschnitt rechteckige, verhältnismäßig flache und sich in Profillängsrichtung erstreckende Nut aufweisen. In diese Nut sind Konsolen eingeschoben, die in montierter Stellung bündig aneinander anliegen können. Dabei kann sich eine Konsole mit einer an ihrem unteren Ende vorgesehenen schrägen Abstützfläche an einer entsprechenden Abstützfläche am oberen Ende der darunter liegenden Konsole abstützen. Der die Ansätze tragende Schenkel jeder Konsole liegt an dem Boden der genannten Profilnut an und trägt pilzkopfartig ausgebildete Zapfen, die in vorgebohrte Löcher im Boden der genannten Profilnut eingedrückt werden. In montierter Lage hintergreifen die pilzkopfartig ausgebildeten Zapfen die genannte Bohrung im Nutboden. Der anliegende Schenkel der Konsole weist an seinem oberen Ende eine Aufnahmekammer für einen Steg der Lamelle auf. Das freie Ende des abstehenden Schenkels ist mit einem von der genannten Aufnahmekammer weggerichteten Haken versehen, der in eine auf der Unterseite der Lamelle vorgesehene Tasche greift. Die Lamelle setzt sich nach unten über den genannten abstehenden Schenkel fort. Die Lamellen weisen an ihrem oberen und unteren Ende jeweils eine Nut auf, wobei die Öffnungen der unteren Nut der jeweils oberen Lamelle und der oberen Nut der jeweils unteren Lamelle etwa auf gleicher Höhe liegen und zueinander zeigen. In die offenen, auf gleicher Höhe angeordneten Nuten können Randteile eines Gitters eingesetzt sein.Such an embodiment can be found in DE-A-29 10877. This prior publication discloses various embodiments for ventilation grilles. The support profiles can be aluminum profiles which have a rectangular cross-section, relatively flat and extending in the longitudinal direction of the profile. Brackets are inserted into this groove, which in the assembled position can lie flush against each other. In this case, a console with an inclined support surface provided at its lower end can be supported on a corresponding support surface at the upper end of the console below. The leg of each bracket bearing the shoulders lies against the bottom of the said profile groove and carries mushroom-shaped pins which are pressed into predrilled holes in the bottom of the said profile groove. In the assembled position, the mushroom-shaped pins engage behind the hole mentioned in the groove bottom. The adjacent leg of the console has a receiving chamber for a web of the lamella at its upper end. The free end of the protruding leg is provided with a hook which is directed away from the said receiving chamber and which engages in a pocket provided on the underside of the lamella. The lamella continues downwards over the projecting leg. The lamellae each have a groove at their upper and lower ends, the openings of the lower groove of the respective upper lamella and the upper groove of the respective lower lamella being approximately at the same height and facing one another. Edge parts of a grating can be inserted into the open grooves arranged at the same height.

Zur Befestigung einer Lamelle sind üblicherweise zumindest zwei im horizontalen Abstand voneinander angeordnete Konsolen vorgesehen. Es müssen somit zumindest zwei lotrechte Tragprofile montiert werden. Da bei der vorbekannten Ausführungsform diese Tragprofile bereits vorgelocht sind. ist eine sehr genaue Ausrichtung bei der Montage erforderlich, um eine absolut horizontale Ausrichtung der einzelnen Lamellen zu gewährleisten. Der oberste und unterste Abstand der Lamellen zum umgebenden Mauerwerk muß dabei schon vor der Montage der gelochten Tragprofile genau bestimmt werden. Nachteilig bei der vorstehend beschriebenen vorbekannten Konstruktion ist ferner, daß die Tragprofile einer zusätzlichen Bearbeitung durch Bohren, Stanzen, Fräsen o. dergl. bedürfen, um die Löcher für die zapfenförmigen Ansätze der Konsolen herzustel- . len.At least two brackets arranged at a horizontal distance from one another are usually provided for fastening a slat. At least two vertical support profiles must therefore be installed. Since in the known embodiment, these support profiles are already pre-punched. a very precise alignment is required during assembly to ensure an absolutely horizontal alignment of the individual slats. The top and bottom distance of the slats to the surrounding masonry must be precisely determined before the perforated support profiles are installed. Another disadvantage of the previously known construction described above is that the support profiles require additional processing by drilling, punching, milling or the like in order to produce the holes for the peg-shaped approaches of the brackets. len.

Der Erfindung 1iegt demgegenüber die Aufgabe zugrunde, eine Befestigungsanordnung der eingangs beschriebenen Art zu erstellen, die eine wesentlich vereinfachte Montage ermöglicht.In contrast, the invention is based on the object of creating a fastening arrangement of the type described at the outset which enables a substantially simplified assembly.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Profil-Ausnehmungen für die Ansätze durch die genannte Nut gebildet sind, in der die Ansätze verschiebbar gehalten sind, und daß die Ansätze am unteren Ende der Konsole einen Aufnahmeraum aufweisen, in den ein Füllstück der darunter angeordneten Konsole klemmend einschiebbar ist, wodurch zugleich die zugeordnete Konsole gegenüber dem Tragprofil fixiert und gegen unerwünschte Längsverschiebung gesichert ist.This object is achieved in that the profile recesses for the approaches are formed by the said groove, in which the approaches are slidably held, and that the approaches have a receiving space at the lower end of the console, in which a filling piece of the arranged below Console can be inserted by clamping, whereby at the same time the assigned console is fixed relative to the supporting profile and secured against undesired longitudinal displacement.

Bei der erfindungsgemäßen Befestigungsanordnung werden die Konsolen in die als Schienen ausgebildeten Tragprofile eingesetzt und sind längs des Tragprofils verschiebbar. Durch das Einschieben des Füllstücks in den Aufnahmeraum der jeweils oberen Konsole wird einerseits eine Fixierung der Lage der Konsole erreicht, andererseits automatisch ein regelmäßiger Abstand zwischen den Lamellen erzeugt, der durch die Länge des anliegenden Schenkels der Konsolen bestimmt ist, weil die klemmende Verbindung zwischen den Konsolen den Abstand festlegt. Vorzugsweise stoßen die jeweils an der Schiene anliegenden Schenkel der untereinander angeordneten Konsolen aneinander.In the fastening arrangement according to the invention, the brackets are inserted into the support profiles designed as rails and can be moved along the support profile. By pushing the filler into the receiving space of the upper console, the position of the console is fixed on the one hand, and on the other hand, a regular distance between the slats is automatically generated, which is determined by the length of the adjacent leg of the console, because the clamping connection between the Brackets set the distance. The legs of the consoles arranged one below the other preferably abut against the rail.

In einer besonders bevorzugten Ausführungsform ist der Ansatz der Konsole federnd ausgebildet, so daß er in die Schiene einschnappbar ist. Dies kann vorzugsweise dadurch realisiert sein, daß der Ansatz durch zwei in Längsrichtung der anliegenden Schenkels verlaufende, mit Abstand voneinander angeordnete Rippen gebildet ist, die mit jeweils einer schrägen Außenfläche Rastvorsprünge für aufeinander zeigende Haltestege der Schienen bilden. Die Konsole kann dadurch an jeder Stelle der Schiene in den Lauf der Schiene eingeschnappt werden, wodurch sie in Längsrichtung der Schiene verschiebbar ist, jedoch nicht mehr von der Schiene abgezogen werden kann.In a particularly preferred embodiment, the extension of the console is designed to be resilient, so that it can be snapped into the rail. This can preferably be achieved in that the extension is formed by two ribs which run in the longitudinal direction of the adjoining legs and are spaced apart from one another and which each form an inclined outer surface with locking projections for holding bars of the rails pointing towards one another. As a result, the console can be snapped into the run of the rail at any point on the rail, as a result of which it can be moved in the longitudinal direction of the rail, but can no longer be pulled off the rail.

In einer konkreten Ausführungsform ragt das Füllstück über das obere Ende des anliegenden Schenkels hinaus. Die den Ansatz bildenden Rippen enden mit dem unteren Ende des anliegenden Schenkels. Das Füllstück der unteren Konsole kann beim Zusammenschieben der Konsolen in den Zwischenraum zwischen den Schenkeln der oberen Konsole einfahren. Der Aufnahmeraum für das Füllstück wird daher durch den Zwischenraum zwischen den beiden Schenkeln gebildet. Um eine definierte Endstellung für die zusammengeschobenen Konsolen zu erhalten, ist es vorteilhaft, wenn das obere Ende des anliegenden Schenkels eine Anlagefläche zur Anlage an dem unteren Ende des anliegenden Schenkels der darüberliegenden Konsole aufweist. Vorteilhaft ist ferner die klemmende Verbindung zwischen dem Füllstück und dem Aufnahmeraum der darüberliegenden Konsole in Form einer Rastung auszuführen.In a specific embodiment, the filler extends beyond the upper end of the adjacent leg. The ribs forming the base end with the lower end of the adjacent leg. The filler piece of the lower bracket can slide into the space between the legs of the upper bracket when the brackets are pushed together. The receiving space for the filler is therefore formed by the space between the two legs. In order to obtain a defined end position for the consoles pushed together, it is advantageous if the upper end of the adjacent leg has a contact surface for contacting the lower end of the adjacent leg of the console above. It is also advantageous to carry out the clamping connection between the filler and the receiving space of the overlying console in the form of a detent.

Das erfindungsgemäße Befestigungssystem mit den aneinander ohne Zwischenraum anschließenden Konsolen erlaubt nicht die bisher übliche Verwendung von Lamellen, die die Konsolen oben und unten übergreifen. Um keine Konsolenteile nach außen hin sichtbar werden zu lassen, weist in einer bevorzugten Ausführungsform der anliegende Schenkel der Konsole an seinem oberen Ende eine Aufnahmekammer für einen Steg der Lamelle auf, wobei das freie Ende des abstehenden Stegs mit einem zur Aufnahmekammer gerichteten Haken versehen ist, der hinter einen mit einem Rastvorsprung versehenen Steg auf der Unterseite der Lamelle greift. Die Lamelle setzt sich über den abstehenden Schenkel nach unten fort. Dies bedeutet, daß die nach unten fortgesetzte Lamelle den oberen Teil der Aufnahmekammer der darunter befindlichen Konsole abdeckt, der von der jeweils in der betreffenden Konsole gehaltenen Lamelle nicht abdeckbar ist. Die Lamelle wird in der Konsole einerseits in der Aufnahmekammer gehalten, andererseits durch die Rastverbindung zwischen dem Befestigungshaken und dem Raststeg befestigt. Die Aufnahmekammer ist dabei so ausgebildet, daß in der durch die Rastung vorgegebenen Winkelstellung der Lamelle diese nicht aus der Aufnahmekammer entweichen kann. Das Entfernen der Lamelle aus der Aufnahmekammer erfordert deren Anheben in eine etwa senkrecht zum anliegenden Steg der Konsole stehenden Stellung.The fastening system according to the invention with the brackets adjoining one another without a space does not permit the previously customary use of slats which overlap the brackets above and below. In order not to make any console parts visible from the outside, in a preferred embodiment the adjoining leg of the console has at its upper end a receiving chamber for a web of the lamella, the free end of the projecting web being provided with a hook directed towards the receiving chamber. which engages behind a web provided with a locking projection on the underside of the slat. The slat continues down over the protruding leg. This means that the slat continued downward covers the upper part of the receiving chamber of the console below, which cannot be covered by the slat held in the respective console. The lamella is held in the bracket on the one hand in the receiving chamber, and on the other hand fastened by the snap connection between the fastening hook and the snap bar. The receiving chamber is designed so that in the angular position of the lamella predetermined by the latching, the lamella cannot escape from the receiving chamber. The removal of the lamella from the receiving chamber requires it to be raised to a position approximately perpendicular to the adjacent web of the console.

Um im montierten Zustand der Konsolen ein Herausfallen der Lamellen zu vermeiden, wenn sich die Rastverbindung zufällig lösen sollte und die Lamelle durch Windsog o.ä. in die waagerechte Position angehoben werden kann, ist das untere Ende des anliegenden Schenkels der Konsole vorzugsweise ein nach unten gerichteter Winkel angesetzt, der mit seinem nach unten gerichteten Winkelteil vor der Öffnung der Aufnahmekammer der unteren Konsole sitzt, wenn diese klemmend mit der oberen Konsole verbunden ist. Durch das Zusammenschieben der Konsolen wird somit der Aufnahmeraum durch das Winkelteil der oberen Konsole verschlossen, so daß auch unter ungünstigen Bedingungen ein Herausfallen der Lamelle aus dem Aufnahmeraum verhindert wird.In order to prevent the slats from falling out when the brackets are installed, if the locking connection should come loose accidentally and the slat is exposed to wind suction or the like. can be lifted into the horizontal position, the lower end of the adjacent leg of the console is preferably set at a downward angle which, with its downward angle part, sits in front of the opening of the receiving chamber of the lower console when it is clampedly connected to the upper console is. By pushing the brackets together, the receiving space is closed by the angular part of the upper bracket, so that the slat is prevented from falling out of the receiving space even under unfavorable conditions.

Die neue Montage der Lamellen ermöglicht die gleichzeitige Befestigung weiterer Elemente, wie etwa eines Gitters, wenn die Lamellen an ihrem oberen und unteren Ende einen Steg in Form einer Nut mit einem etwas mehr als halbkreisförmigen Querschnitt aufweisen, wobei die Öffnungen der unteren Nut der oberen Lamelle und der oberen Nut der unteren Lamelle etwa auf gleicher Höhe liegen und zueinander zeigen. Die offenen Nuten der Lamellen können zur Aufnahme weiterer Elemente verwendet werden. Vorzugsweise halten die auf der gleichen Höhe angeordneten, offenen Nuten ein Luftgitter, indem sie die verdickten Randteile des Gitters aufnehmen. Bestehen die Randteile aus einem elastischen Material. kann eine sichere rastende Verbindung hergestellt werden.The new assembly of the slats enables the simultaneous attachment of further elements, such as a grid, if the slats have a web in the form of a groove with a slightly more than semicircular cross section at their upper and lower ends, the openings of the lower groove of the upper slat and the upper groove of the lower lamella lie approximately at the same height and point towards each other. The open grooves of the slats can be used to hold additional elements. The open grooves arranged at the same height preferably hold an air grille by receiving the thickened edge parts of the grille. The edge parts are made of an elastic material. a secure locking connection can be established.

Figur 1 zeigt zwei untereinander angeordnete Lamellen 1, die an zwei Konsolen 2 durch Einstecken und Aufschnappen befestigt sind. Die Konsolen sind mit Ansätzen 3 versehen, mit denen sie in einem als Schiene ausgebildeten Tragprofil 4 in dessen Längsrichtung, in der Darstellung der Figur 1 also vertikal, verschiebbar sind.Figure 1 shows two mutually arranged slats 1, which are attached to two brackets 2 by plugging and snapping. The brackets are provided with lugs 3 with which they can be displaced in a support profile 4 designed as a rail in the longitudinal direction thereof, that is to say vertically in the illustration in FIG. 1.

Die Konsolen 2 bestehen im wesentlichen aus einem an dem Tragprofil 4 anliegenden Schenkel 5 sowie einem von dem Tragprofil 4 senkrecht abstehenden Schenkel 6. Zur Erhöhung der Stabilität sind die beiden Schenkel 5, 6 durch ein Mittelteil 7 miteinander verbunden. Der anliegende Schenkel 5 weist an seinem oberen Ende eine Aufnahmekammer 8 für einen als offene Nut ausgebildeten Steg 9 am oberen Ende der Lamelle 1 auf. Die Aufnahmekammer 8 ist vom oberen Ende schräg nach unten geöffnet, also etwa in Richtung des Hauptkörpers der Lamelle 1 im montierten Zustand.The brackets 2 essentially consist of a leg 5 resting on the support profile 4 and a leg 6 projecting perpendicularly from the support profile 4. To increase the stability, the two legs 5, 6 are connected to one another by a central part 7. The adjacent leg 5 has at its upper end a receiving chamber 8 for a web 9 designed as an open groove at the upper end of the lamella 1. The receiving chamber 8 is opened obliquely downwards from the upper end, that is to say approximately in the direction of the main body of the lamella 1 in the assembled state.

Das freie Ende des abstehenden Schenkels 6 der Konsole 2 ist schräg nach oben zur Aufnahmekammer 8 zeigend hochgebogen und bildet einen Befestigungshaken 10. Die Lamelle 1 weist an ihrer Unterseite eine in Längsrichtung verlaufende, mit einem Rastvorsprung versehene Rippe 11 auf. Die Montage der Lamelle an der Konsole erfolgt durch Einsetzen des Stegs 9 in die Aufnahmekammer 8 im etwa waagerechten Zustand der Lamelle 1 und durch anschließendes Herunterschwenken der Lamelle, bis der Steg 11 mit seinem Rastvorsprung hinter den Befestigungshaken 10 des abstehenden Schenkels 6 der Konsole 2 schnappt. Die Lamelle 1 setzt sich im montierten Zustand bis unter den abstehenden Schenkel 6 der Konsole fort und weist eine im montierten Zustand zum Tragprofil 4 hin offene Nut 12 mit ebenfalls kreisförmigem Querschnitt auf. Die Lamelle ist an ihrer Unterseite mit einer Abtropfkante 13 abgeschlossen.The free end of the protruding leg 6 of the bracket 2 is bent upward obliquely upward to the receiving chamber 8 and forms a fastening hook 10. The lamella 1 has on its underside a rib 11 running in the longitudinal direction and provided with a locking projection. The lamella is mounted on the console by inserting the web 9 into the receiving chamber 8 in the approximately horizontal state of the lamella 1 and then pivoting the lamella downwards until the web 11 snaps behind the fastening hook 10 of the projecting leg 6 of the console 2 with its latching projection . In the assembled state, the lamella 1 continues to below the protruding leg 6 of the console and has a groove 12 which is open towards the supporting profile 4 in the assembled state and also has a circular cross section. The bottom of the lamella is closed with a drip edge 13.

Figur 2 verdeutlicht den Aufbau des Ansatzes 3 der Konsole 2 sowie die Führung der Konsole 2 in dem als Schiene ausgebildeten Tragprofil 4. Das Tragprofil 4 ist als mit einem Längsschlitz versehenen Rechteckprofil ausgebildet, weist also zur Begrenzung des Schlitzes zwei aufeinander zeigende Haltestege 14. Der Ansatz 3 der Konsole 2 ist durch zwei in Längsrichtung des anliegenden Schenkels 5 verlaufende, einen Zwischenraum 15 zwischen sich bildende Rippen 16 realisiert, die mit jeweils einer schräg verlaufenden Außenfläche 17 einen Rastvorsprung für die Haltestege 14 bilden.Figure 2 illustrates the structure of the approach 3 of the console 2 and the guidance of the console 2 in the support profile 4 designed as a rail. The support profile 4 is designed as a rectangular profile provided with a longitudinal slot, so has two mutually pointing retaining webs 14 to limit the slot Approach 3 of the console 2 is realized by two ribs 16 which run in the longitudinal direction of the adjacent leg 5 and which form an intermediate space 15 between them, each of which forms a locking projection for the holding webs 14 with an inclined outer surface 17.

Der Abstand zwischen den Außenflächen am vorderen Ende der Rippen 16 ist kleiner als der Abstand zwischen den Haltestegen 14. Durch Ansetzen der Rippen 16 zwischen den Haltestegen 14 und Ausüben eines Drucks in Richtung des Tragprofils 4 werden die etwas elastisch ausgebildeten Rippen 16 in Richtung aufeinander gedrückt, so daß die Stege hinter die durch die Rippen 16 gebildeten Rastvorsprünge greifen können. Zur Unterstützung des Einschnappvorgangs sind die Endflächen der Haltestege 14 ebenfalls als Schrägen 18 ausgebildet.The distance between the outer surfaces at the front end of the ribs 16 is smaller than the distance between the holding webs 14. By applying the ribs 16 between the holding webs 14 and exerting pressure in the direction of the support profile 4, the somewhat elastic ribs 16 are pressed towards one another , so that the webs can engage behind the locking projections formed by the ribs 16. To support the snap-in process, the end faces of the holding webs 14 are also designed as bevels 18.

Am oberen Ende des anliegenden Stegs 5 und diesen nach oben überragend ist ein Füllstück 19 in der Breite des Zwischenraums 15 zwischen den beiden Rippen 16 vorgesehen. Beim Zusammenschieben der beiden Konsolen 2 fährt das Füllstück 19, das zu diesem Zweck nach oben etwas verjüngt ausgebildet sein kann, in den Zwischenraum 15 ein. Dadurch werden die Rippen 16 etwas nach außen gedrückt und bilden mit den Haltestegen 14 des Tragprofils 4 einen Kraftschluß, der die Bewegung der Konsole 2 in Längsrichtung des Halteprofils 4 nunmehr verhindert. Durch das Einschieben des Füllstücks 19 der unteren Konsole 2 in den Zwischenraum 15 zwischen den Rippen 16 der oberen Konsole 2 wird daher die obere Konsole 2 an der Tragschiene 4 arretiert.At the upper end of the adjacent web 5 and projecting above it, a filler 19 is provided in the width of the space 15 between the two ribs 16. When the two brackets 2 are pushed together, the filler piece 19, which for this purpose can be slightly tapered upwards, moves into the intermediate space 15. As a result, the ribs 16 are pressed somewhat outward and form a frictional connection with the holding webs 14 of the supporting profile 4, which now prevents the movement of the bracket 2 in the longitudinal direction of the holding profile 4. By pushing the filler 19 of the lower bracket 2 into the space 15 between the ribs 16 of the upper bracket 2, the upper bracket 2 is therefore locked on the mounting rail 4.

Wie Figur 1 verdeutlicht, liegen die obere Nut 9 der unteren Konsole 2 und die untere Nut 12 der oberen Konsole 2 auf gleicher Höhe und zeigen mit ihren Öffnungen zueinander. Die Nuten 9, 12 sind daher zur Aufnahme zusätzlicher Elemente wie Luftgitter 20, Siebe o.ä. in die Lamellenöffnungen geeignet. In Figur 1 ist ein Luftgitter 20 dargestellt, das mit verdickten Randteilen 21 in die Nuten 9, 12 eingedrückt ist.As illustrated in FIG. 1, the upper groove 9 of the lower bracket 2 and the lower groove 12 of the upper bracket 2 are at the same height and face one another with their openings. The grooves 9, 12 are therefore for receiving additional elements such as air grilles 20, sieves or the like. suitable in the slat openings. In Figure 1, an air grille 20 is shown, which is pressed into the grooves 9, 12 with thickened edge parts 21.

Figur 4 zeigt eine modifizierte Ausführungsform der Konsole 2, bei der am unteren Ende des anliegenden Stegs ein Winkelstück 22 angesetzt ist, das mit einem nach unten ragenden Winkelteil 23 die Öffnung der Aufnahmekammer 8 der darunter angeordneten Konsole 2 so weit verschließt. daß der Steg 9 der Lamelle 1 nicht mehr aus der Aufnahmekammer 8 entfernt werden kann, wenn die beiden Konsolen über das Füllstück 19 miteinander verbunden sind.FIG. 4 shows a modified embodiment of the console 2, in which an angle piece 22 is attached to the lower end of the adjoining web and closes the opening of the receiving chamber 8 of the console 2 arranged below so far with a downwardly protruding angle part 23. that the web 9 of the lamella 1 can no longer be removed from the receiving chamber 8 when the two brackets are connected to one another via the filler 19.

Zur Gewährleistung einer definierten Montagestellung der miteinander verbundenen Konsolen 2/an Weisen diese ihren oberen Enden eine ebene Anlagefläche 24 auf, die im montierten Zustand an dem abstehenden Schenkel 6 der jeweils oberen Konsole anliegt und für die Montage einen Anschlag bildet. Diese Montage kann noch dadurch unterstützt werden, daß beim Einschieben des Füllstücks 19 in den Zwischenraum 15 der darüber angeordneten Konsole 2 eine Rastung realisiert wird, so daß das vollständige Einschieben der unteren Konsole in die obere Konsole auch durch das Knacken der Rastmittel hörbar wird.To ensure a defined mounting position of the interconnected consoles 2 /, they have a flat contact surface 24 at their upper ends, which in the assembled state rests against the protruding leg 6 of the respective upper console and forms a stop for the assembly. This assembly can be supported by the fact that when the filler 19 is inserted into the intermediate space 15 of the console 2 arranged above, a detent is realized, so that the complete insertion of the lower console into the upper console can also be heard by the click of the latching means.

Es ist ersichtlich, daß die erfindungsgemäße Befestigungsanordnung eine außerordentlich einfache Montage ohne die Notwendigkeit von Verschraubungen erlaubt und durch die abstandslose Aneinanderreihung der Konsolen 2 immer einen gleichmäßigen Abstand zwischen den Lamellen 1 gewährleistet.It can be seen that the fastening arrangement according to the invention allows an extremely simple assembly without the need for screw connections and always ensures a uniform spacing between the slats 1 due to the spacing of the brackets 2.
