Description

Die Erfindung betrifft eine Rasterdecke mit im Querschnitt U-förmigen Lamellen, mit an deren Stirnseiten angeordneten, sie überbrückenden Randlamellen und mit die Randlamellen mit den überbrückten lamellen verbindenden Halteelementen, die an den Randlamellen befestigt und in die stirnseitigen Enden der überbrückten Lamellen eingesteckt sind.The invention relates to a grid ceiling with cross-sectionally U-shaped slats, with arranged on their end faces, bridging edge slats and with the edge slats with the bridged slats connecting holding elements, which are attached to the edge slats and inserted into the front ends of the bridged slats.

Eine solche Rasterdecke ist aus der DE-A-2721 541 bekannt. Das Halteelement ist eine U-Schiene. Ihr Steg ist an der Randlamelle befestigt. Die überbrückte Lamelle ist auf die Schenkel der U-Schiene aufgesteckt.Such a grid ceiling is known from DE-A-2721 541. The holding element is a U-rail. Your bridge is attached to the edge lamella. The bridged slat is attached to the legs of the U-rail.

Durch die Erfindung soll die Aufgabe gelöst werden, die Verbindung zwischen den Lamellen so auszubilden, daß die Lamellen auch dann haltbar miteinander verbunden und zerstörungsfrei wieder demontiert werden können, wenn die Lamellen nur kleine Strecken bewegt werden können, beispielsweise wegen einer benachbarten Gebäudewand. Ferner soll die Verbindung so gestaltet sein, daß die Randlamellen über ihre gesamte Höhe die gewünschte Länge beibehalten und nicht oben oder unten von den Stirnseiten der überbrückten Lamellen sich unerwünscht wegbewegen.The invention aims to solve the problem of designing the connection between the slats in such a way that the slats can also be securely connected to one another and disassembled without being destroyed if the slats can only be moved over small distances, for example because of an adjacent building wall. Furthermore, the connection should be designed so that the edge slats maintain the desired length over their entire height and do not undesirably move away from the top or bottom of the end faces of the bridged slats.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß die Halteelemente die Form von, vorzugsweise federnden, Krallen haben, welche sich zwischen den Schenkeln der überbrückten Lamellen festkrallen, in deren Stirnseiten sie eingesteckt sind.This object is achieved according to the invention in that the holding elements are in the form of, preferably resilient, claws which grip between the legs of the bridged slats, in the end faces of which they are inserted.

Weitere Merkmale ergeben sich aus den Unteransprüchen.Further features emerge from the subclaims.

Eine Ausführungsform der Erfindung wird im folgenden mit Bezug auf die Zeichnungen als Beispiel beschrieben. In diesen zeigt

  • Fig. 1 eine Rasterdecke von unten gesehen,
  • Fig.2 eine perspektivische Draufsicht auf einen vergrößert dargestellten Teil der Rasterdekke von Fig. 1,
  • Fig.3 eine Innenansicht eines Deckels zum Abschluß einer U-förmigen Lamelle, und
  • Fig. 4 einen Schnitt längs der Ebene IV-IV in Fig. 3, welcher ein als Kralle ausgebildetes Halteelement zeigt.
An embodiment of the invention will be described below with reference to the drawings as an example. In these shows
  • 1 seen a grid ceiling from below,
  • 2 shows a perspective top view of an enlarged part of the grid ceiling of FIG. 1,
  • 3 shows an interior view of a cover for completing a U-shaped lamella, and
  • Fig. 4 is a section along the plane IV-IV in Fig. 3, which shows a holding element designed as a claw.

Fig. 1 zeigt eine Rasterdecke. Diese ist entsprechend Fig. 2 mit Vorrichtungen 60 an einer Gebäudedecke aufgehängt und hat im Querschnitt im wesentlichen U-förmige Längslamellen 21, Querlamellen 22, Rand-Längslamellen 23 und Rand-Querlamellen 24 mit je zwei nach oben weisenden Schenkeln 25 und 26 und einem deren unteres Ende verbindenden Steg 27. An den oberen Enden der Schenkel 25 und 26 der Längslamellen 21 und der Querlamellen 22 befinden sich stirnseitig nach vorne und nach unten weisende Haken 28. Die Haken 28 sind in paarweise angeordnete Schlitze 29 der Schenkel 25 und 26 der betreffenden anderen Lamellen 21, 23, 24 einhängbar. Unterhalb der Schlitze 29 befinden sich Nocken 30 bzw. 31, über welche die Schenkel 25 und 26 hinweggreifen und dadurch in seitlicher Lage fixiert werden. Die Nocken 30 sind als Sicken und die Nocken 31 als bügelartige Ausprägungen gezeichnet. Die Nocken 30 sind soweit unterhalb der Schlitze 29 angeordnet, daß sie an der Innenfläche des Steges 27 der eingehängten Querlamelle 22 einrasten und sie an einem unbeabsichtigten Anheben nach oben londern.Fig. 1 shows a grid ceiling. This is suspended according to Fig. 2 with devices 60 on a building ceiling and has in cross-section substantially U-shaped longitudinal slats 21, transverse slats 22, longitudinal edge slats 23 and edge transverse slats 24, each with two legs 25 and 26 pointing upwards and one of them lower end connecting web 27. At the upper ends of the legs 25 and 26 of the longitudinal lamellae 21 and the transverse lamellae 22 there are front-facing and downward-facing hooks 28. The hooks 28 are slots 29 of the legs 25 and 26 of the respective legs arranged in pairs other slats 21, 23, 24 can be suspended. Below the slots 29 there are cams 30 and 31, respectively, over which the legs 25 and 26 extend and are thereby fixed in a lateral position. The cams 30 are drawn as beads and the cams 31 as bow-like shapes. The cams 30 are arranged so far below the slots 29 that they snap into place on the inner surface of the web 27 of the suspended transverse lamella 22 and lend them upwards when inadvertently raised.

Wenn die Lamellen nur oben eingehängt und an einer tiefer gelegenen Stelle an einer seitlichen Bewegung durch Nocken gehindert werden, dann besteht bei den Rand-Querlamellen 24 immer noch die Gefahr, daß ihr unteres Ende mit dem Steg 27 nicht sauber an den Längslamellen 21 anliegt, sondern nach hinten ausweichend absteht, weil auf der Rückseite der Rand-Querlamellen 24 kein Gegenelement mehr vorhanden ist. Aus diesem Grunde sind die Rand-Querlamellen 24 an ihrem den Längslamellen 21 zugewandten Schenkel 26, nahe ihres unteren Endes beim Steg 27, mit einem Halteelement versehen. Dieses wird beim Einhängen der Längslamellen 21 in deren Stirnseiten eingesteckt und hält dann diese Lamellen 21 und 24 zusammen. Die Rand-Längslamellen 23 haben stirnseitig keine Haken, sondern werden durch je zwei mit Abstand übereinander angeordnete Halteelemente 36 der Rand-Querlamellen 24 gehalten, von denen ein Halteelement 36 am oberen Ende und das andere Halteelement 36 am unteren Ende in das stirnseitige Ende einer Rand-Längslamelle 23 eingreift.If the lamellae are only hooked in at the top and are prevented from moving laterally by cams at a lower point, then there is still the danger with the transverse edge lamellae 24 that their lower end with the web 27 does not lie properly against the longitudinal lamellae 21, but protrudes backwards out of the way, because there is no counter element on the back of the edge cross blades 24. For this reason, the edge transverse lamellae 24 are provided with a holding element on their leg 26 facing the longitudinal lamellae 21, near their lower end near the web 27. This is inserted into the end faces when the longitudinal slats 21 are hung in and then holds these slats 21 and 24 together. The longitudinal edge lamellae 23 have no hooks on the end face, but are held by two holding elements 36 of the edge transverse lamellae 24, which are spaced one above the other, one holding element 36 at the upper end and the other holding element 36 at the lower end into the front end of an edge -Longitudinal lamella 23 engages.

Die Halteelemente 36 haben die Form von federnden Krallen, weiche sich zwischen den Schenkeln 25 und 26 der Lamellen festkrallen, in deren Stirnseiten sie eingesteckt sind. Einzelheiten der Halteelemente 36 sind aus den Fig. 3 und 4 ersichtlich, welche einen mit solchen Krallen versehenen Deckel 37 zum Verschließen der sichtbaren Stirnseite 38 der Rand-Querlamelle 24 zeigen. Die Halteelemente 36 weisen jeweils zwei Steckerteile 39 und 40 und einen diese verbindenden Stegteil 10 auf. Die Steckerteile 39 und 40 haben nach außen weisende Krallenspitzen 41 und 42, die sich jeweils von innen in die Schenkel 25 und 26 der Lamellen einkrallen, und nach innen einander zugewandte Krallenkanten 43 und 44. Durch schlitzartige Ausnehmungen 11 und 12 an den Enden der Steckerteile 39 und 40 ergeben sich Haken mit den Krallenspitzen 41 und 42 und diese Krallenspitzen 41 und 42 sowie die Krallenkanten 43 und 44 sind in der Hakenebene federnd nachgiebig.The holding elements 36 have the form of resilient claws, which claw between the legs 25 and 26 of the slats, in the end faces of which they are inserted. Details of the holding elements 36 can be seen from FIGS. 3 and 4, which show a cover 37 provided with such claws for closing the visible end face 38 of the edge transverse lamella 24. The holding elements 36 each have two plug parts 39 and 40 and a web part 10 connecting them. The plug parts 39 and 40 have outward-pointing claw tips 41 and 42, each of which claws from the inside into the legs 25 and 26 of the lamellae, and claw edges 43 and 44 facing one another inwards. Through slot-like recesses 11 and 12 at the ends of the plug parts 39 and 40 result in hooks with the claw tips 41 and 42 and these claw tips 41 and 42 and the claw edges 43 and 44 are resilient in the hook plane.

Am oberen Schenkelende der Lamellen dienen die Halteelemente 36 nicht nur zum Festhalten dieser Lamellen, sondern auch zur Abstandshalterung der Lamellenschenkel, damit diese beim Einstecken der Halteelemente 36 nicht auseinandergebogen werden. Wie Fig. 2 zeigt, sind die Schenkel 25 und 26 der Lamellen 21, 22, 23 und 24 am oberen Schenkelende zweimal nach innen abgewinkelt. Dadurch sind horizontal einander zugewandte Zwischenabschnitte 46 und 47 sowie sich daran abgewinkelt anschließende, V förmig in das Lamelleninnere aufeinander zulaufende Endabschnitte 48 und 49 gebildet, deren Ränder unter Bildung einer längsverlaufenden Öffnung 50 einen bestimmten Abstand voneinander haben. Dadurch können die Steckerteile 39 und 40 am oberen Lamellenende jeweils zwischen die inneren Endabschnitte 48 und 49 sowie die äußeren Schenkelabschnitte 51 und 52 eingedrückt werden. Der schräge Verlauf der Schenkelendabschnitte 48 und 49 gleicht Herstellungs- und Montageungenauigkeiten aus, da sie von den Halteelementen 36 auch dann erfaßt werden und nachgiebig sind, wenn die Halteelemente 36 nicht genau ihre vorbestimmte Lage einnehmen.At the upper leg end of the lamellae, the holding elements 36 serve not only to hold these lamellae in place, but also to maintain the spacing of the lamella legs so that they are not bent apart when the holding elements 36 are inserted. 2 shows, the legs 25 and 26 of the slats 21, 22, 23 and 24 at the upper leg end are angled twice inwards. As a result, horizontally facing intermediate sections 46 and 47 and adjoining them at an angle, V-shaped end sections 48 and 49 are formed in the lamella interior, the edges of which have a certain distance from one another, forming a longitudinal opening 50. As a result, the plug parts 39 and 40 at the upper lamella end can each be pressed in between the inner end sections 48 and 49 and the outer leg sections 51 and 52. The oblique course of the leg end sections 48 and 49 compensates for manufacturing and assembly inaccuracies, since they are also gripped by the holding elements 36 and are flexible when the holding elements 36 do not exactly assume their predetermined position.
