  • the object is therefore to create a false ceiling of the type mentioned at the outset, in which the manufacture and assembly of the hinged cassettes is simplified, and yet the security against unwanted removal is increased, in particular in the folded position.
  • the solution to this problem consists essentially in the fact that the end flange in the region of its edge facing away from the cassette surface each has a protrusion protruding in one piece against the support profile beyond the cutout and that the support profile has supporting flanges pointing to the side of its locking joint towards the center of the cassette and the cutouts in the position of use overlap the supporting flanges by means of the projections.
  • each of the protrusions on the end flanges can be reached by folding down the cassette jump to the top of the support flange of the support profile, so that the cassette then hangs on it in a form-fitting manner, but is advantageously also displaceable in the direction of the support profile.
  • an unwanted unhooking is practically impossible, which is conceivable if a swivel bearing would be provided within the locking joint.
  • a particularly secure mounting of a folded cassette is obtained if the support flange of the support profile has a free edge at its free edge in the use position and the projection on the cutout of the end flange has a hook shape with an end piece pointing downwards in the use position.

Description

Die Erfindung betrifft eine Unterdecke mit abgehängten, eine in ihrer Längsrichtung verlaufende, nach unten offene Rastfuge aufweisenden Tragprofilen und daran befestigten, insbesondere viereckigen Kassetten, die an ihren den Trag­profilen zugewandten und in Gebrauchsstellung dazu parallel laufenden Rändern hochstehende Halteflansche mit Rast­stellen od. dgl. zum Einschieben in die Rast- oder Klemm­fuge der Tragprofile haben, wobei zumindest einzelne Kassetten zusätzlich zu ihrer Verrastung an einem Ende ihrer Halteflansche eine Schwenklagerung haben, die ein Abklappen der Kassette zum Freigeben der Montageöffnungen ermöglicht, wobei die abgeklappte Kassette mittels ihrer Schwenklagerung an den Tragprofilen hängt, und wobei die Kassette zumindest im Bereich ihres Schwenklagers einen rechtwinklig zum Tragprofil verlaufenden hochstehenden Endflansch mit einem Ausschnitt jeweils an den den Trag­profilen zugewandten Enden hat.The invention relates to a suspended ceiling with a supporting profile that extends in the longitudinal direction and has a latching joint that is open at the bottom, and attached to it, in particular square cassettes, that have upstanding holding flanges with latching points or the like on their edges facing the supporting profiles and running parallel to them in the position of use Have insertion into the locking or clamping joint of the support profiles, at least individual cassettes have, in addition to their locking at one end of their holding flanges, a swivel mounting that allows the cassette to be folded down to open the assembly openings, the folded cassette hanging on the support profiles by means of its swivel mounting , and wherein the cassette has, at least in the region of its pivot bearing, an upstanding end flange which extends at right angles to the support profile and has a cutout at the ends facing the support profiles.

Derartige Unterdecken mit Kassetten sind bekannt. Dabei gibt es bereits eine Vielzahl von Tragprofilen, die je­weils an ihrer Unterseite einen Klemmschlitz oder eine Rastfuge haben, damit die hochstehenden Halteflansche der Kassetten darin in Gebrauchstellung verrastet werden können.Such ceilings with cassettes are known. There are already a variety of support profiles, each with a clamping slot or a bottom Have a locking joint so that the upstanding retaining flanges of the cassettes can be locked in the use position.

Bei einer bekannten Unterdecke dieser Art ist für die Schwenklagerung der abklappbaren Kassetten ein spezielles Gelenkstück vorgesehen, welches einerseits an dem hoch­stehenden Kassettenrand angenietet und andererseits an dem Tragprofil schwenkbar befestigt werden muß. Dabei muß dieses Gelenkstück winklig ausgebildet sein, damit bei der Abklappbewegung um die beiden dabei mit Abstand zu­einander angeordneten Schwenkpunkte der Endflansch der klappbaren Kassette genügend Abstand von der Nachbarkas­sette erhält. Somit muß an der Kassette und dem Tragprofil ein zusätzliches Teil, nämlich das erwähnte Gelenkstück angebracht werden, welches außerdem zuvor angefertigt werden muß.In a known false ceiling of this type, a special joint piece is provided for the pivoting mounting of the hinged cassettes, which on the one hand is riveted to the upstanding cassette edge and, on the other hand, has to be pivotally attached to the support profile. This hinge piece must be angular so that the end flange of the collapsible cassette receives sufficient distance from the neighboring cassette during the folding movement around the two pivot points arranged at a distance from one another. Thus, an additional part, namely the mentioned joint piece, must be attached to the cassette and the support profile, which must also be prepared beforehand.

Es besteht deshalb die Aufgabe, eine Unterdecke der ein­gangs erwähnten Art zu schaffen, bei welcher die Her­stellung und die Montage der abklappbaren Kassetten ver­einfacht ist, und dennoch die Sicherheit gegen ungewolltes Aushängen insbesondere in abgeklappter Lage vergrößert ist.The object is therefore to create a false ceiling of the type mentioned at the outset, in which the manufacture and assembly of the hinged cassettes is simplified, and yet the security against unwanted removal is increased, in particular in the folded position.

Die Lösung dieser Aufgabe besteht im wesentlichen darin, daß der Endflansch im Bereich seines von der Kassetten­oberfläche abgewandten Randes jeweils einen gegen das Tragprofil hin über den Ausschnitt ragenden, einstückig angebrachten Vorsprung hat und daß das Tragprofil seitlich seiner Rastfuge zur Mitte der Kassette hinweisende Trag­flansche hat und die Ausschnitte in Gebrauchsstellung die Tragflansche mittels der Vorsprünge übergreifen. Wird die Rastverbindung der Halteflansche an den Rastfugen der Tragprofile gelöst, gelangt durch das Abklappen der Kas­sette jeder der an den Endflanschen befindlichen Vor­ sprüngen auf die Oberseite des Tragflansches des Trag­profiles, so daß dann die Kassette daran formschlüssig hängt, in vorteilhafter Weise zusätzlich aber in Richtung des Tragprofiles verschiebbar ist. Ein ungewolltes Aus­hängen ist dabei jedoch praktisch unmöglich, welches immerhin dann denkbar ist, wenn eine Schwenklagerung inner­halb der Rastfuge vorgesehen wäre.The solution to this problem consists essentially in the fact that the end flange in the region of its edge facing away from the cassette surface each has a protrusion protruding in one piece against the support profile beyond the cutout and that the support profile has supporting flanges pointing to the side of its locking joint towards the center of the cassette and the cutouts in the position of use overlap the supporting flanges by means of the projections. If the snap-in connection of the holding flanges on the snap-in joints of the support profiles is released, each of the protrusions on the end flanges can be reached by folding down the cassette jump to the top of the support flange of the support profile, so that the cassette then hangs on it in a form-fitting manner, but is advantageously also displaceable in the direction of the support profile. However, an unwanted unhooking is practically impossible, which is conceivable if a swivel bearing would be provided within the locking joint.

Eine besonders sichere Halterung einer abgeklappten Kas­sette ergibt sich, wenn der Tragflansch des Tragprofiles an seinem freien Rand einen in Gebrauchsstellung nach oben stehenden Randsteg hat und der Vorsprung an dem Ausschnitt des Endflansches eine Hakenform mit einem in Gebrauchs­stellung nach unten weisenden Endstück hat. Dieses End­stück kann dann vor allem während des Abklappens auch nach der Seite hin in Formschluß mit dem Randsteg des Trag­flansches treten. In abgeklappter Position ist dann die Kassette nach allen Seiten hin genügend gesichert und kann nicht einmal angehoben werden, weil der Ausschnitt seiner­seits dann von unten her gegen den Tragflansch stoßen würde. Die seitliche Ausdehnung des Vorsprunges kann näm­lich bis nahe an die Ebene reichen, in welcher der paral­lel zum Tragprofilverlauf orientierte Halteflansch ange­ordnet ist. Somit ist ein Einhängen der Kassette nur in einer gewissen Schräglage relativ zu den Tragprofilen mög­lich, die unabsichtlich beim Abklappen kaum eingenommen werden kann, zumal dabei gleichzeitig auch eine Anhebebe­wegung über den Randsteg des Tragflansches zum ein- bzw. aushängen erforderlich wäre.A particularly secure mounting of a folded cassette is obtained if the support flange of the support profile has a free edge at its free edge in the use position and the projection on the cutout of the end flange has a hook shape with an end piece pointing downwards in the use position. This end piece can then come into positive engagement with the edge web of the supporting flange, especially when it is being folded down. In the folded-down position, the cassette is then sufficiently secured on all sides and cannot even be raised because the cutout would then hit the supporting flange from below. The lateral extension of the projection can namely reach close to the plane in which the holding flange, which is oriented parallel to the profile of the supporting profile, is arranged. Thus, the cassette can only be hung in a certain inclined position relative to the supporting profiles, which can hardly be inadvertently taken when folding down, especially since at the same time a lifting movement over the edge web of the supporting flange would also be necessary for hanging in or out.

Um ein erstes Einhängen oder gegebenenfalls auch ein Aus­hängen dennoch auch zu ermöglichen, ist es zweckmäßig, wenn der Endbereich der Halteflansche nahe dem Einhänge­ausschnitt mit Vorsprung ebenfalls einen Ausschnitt hat, so daß in Längsrichtung des Halteflansches zwischen dem Vorsprung und der Oberseite des Halteflansches ein Ein­hängezwischenraum für die Kassette frei bleibt.In order to enable a first hooking in or possibly also a hooking out, it is expedient if the end region of the holding flanges near the hooking cutout with a projection also has a cutout, so that in the longitudinal direction of the holding flange between the Projection and the top of the retaining flange a space between the cassette remains free.

Eine besonders einfache Herstellung ergibt sich, wenn die Kassette aus Blech geformt ist und ihre Randflansche hoch­gebogen sowie die Ausschnitte und der Vorsprung ausge­stanzt sind. Es ist aber auch eine Fertigung aus Kunst­stoff möglich, wobei wiederum vorteilhaft ist, daß die Kassette schon ihre Schwenklagerung für ein formschlüssiges Zusammenwirken mit dem Tragflansch des Tragprofiles ein­stückig aufweisen kann.A particularly simple manufacture results if the cassette is formed from sheet metal and its edge flanges are bent up and the cutouts and the projection are punched out. However, it is also possible to manufacture it from plastic, it again being advantageous that the cassette can already have its pivot bearing in one piece for a form-fitting interaction with the supporting flange of the supporting profile.

Der Ausschnitt an dem rechtwinklig zum Tragprofil ver­laufenden Endflansch der Kassette kann auf der dem Halte­flansch zugewandten Seite unterhalb des Einhängevorsprunges seitlich offen sein und an der dieser Öffnung gegenüber­liegenden Seite kann eher eine zum Rand des Flansches ver­laufende Begrenzung haben, von welcher der Einhängevor­sprung gegen das Tragprofil hin vorsteht. Dadurch ergibt sich zusammen mit dem Einhängevorsprung ein Ausschnitt mit einem relativ engem Eintritt, welcher in seinem Inneren aber erweitert ist, so daß er die gewünschten Schwenkbe­wegungen erlaubt und dennoch auch in jeder Position den Tragflansch des Tragprofiles mittels seiner seitlichen Öffnung umschließen kann.The cutout on the end flange of the cassette running at right angles to the support profile can be open on the side on the side facing the holding flange below the hook-in projection and on the side opposite this opening can rather have a boundary running to the edge of the flange, from which the hook-in projection against the support profile protrudes. This results in a cutout together with the hanging projection with a relatively narrow entrance, but which is expanded inside, so that it allows the desired pivoting movements and can nevertheless enclose the supporting flange of the supporting profile in any position by means of its lateral opening.

Die Oberseite des Einhängevorsprunges kann dabei bündig mit dem oberen Rand des Endflansches sein. Praktisch stellt dann der Einhängevorsprung eine Fortsetzung des End­flansches dar, welcher Endflansch aber unterhalb des Vor­sprunges teilweise ausgestanzt ist.The top of the hanging projection can be flush with the upper edge of the end flange. In practice, the hanging projection then represents a continuation of the end flange, which end flange is, however, partially punched out below the projection.

Vor allem bei Kombination einzelner oder mehrerer der vor­beschriebenen Merkmale und Maßnahmen ergibt sich eine Unterdecke mit Kassette, die ein sicheres und festes Be­ festigen der Kassette in Gebrauchsstellung aber auch ein einfaches Abklappen erlaubt, ohne daß das Abklappen die Gefahr einer Lösebewegung der gesamten Kassette von den Tragprofilen zur Folge hätte, wobei aber in vorteilhafter Weise zusätzliche Gelenkstücke od. dgl. Einzelteile und deren Herstellung und Montage vermieden werden.Especially when combining one or more of the features and measures described above, there is a false ceiling with a cassette, which is a safe and firm loading fix the cassette in the position of use but also allows easy folding, without the folding would have the risk of a loosening movement of the entire cassette from the support profiles, but in an advantageous manner additional joint pieces or the like. Individual parts and their manufacture and assembly are avoided.

Nachstehend ist die Erfindung mit ihren ihr als wesent­lich zugehörenden Einzelheiten anhand der Zeichnung noch näher beschrieben. Es zeigt in schematisierter Dar­stellung :

  • Fig. 1 eine Ansicht einer erfindungsgemäßen Unterdecke mit einer abgeklappten Kassette,
  • Fig. 2 eine Seitenansicht eines Tragprofiles mit einer teilsweise abgeklappten Kassette,
  • Fig. 3 eine Stirnansicht der Kassette mit Blick auf den Endflansch, welcher Einhängevorsprünge zum Zu­sammenwirken mit Tragflanschen an den Tragpro­filen hat, und in vergrößtertem Maßstab
  • Fig. 4 die durch einen Kreis in Fig. 3 markierte Einzel­heit, insbesondere die Verrastung des Halte­flansches an dem Tragprofil und die Ausbildung des Einhängevorsprunges an dem Endflansch der Kassette.
The invention is described in more detail below with its details that are essential to it, using the drawing. It shows in a schematic representation:
  • 1 is a view of a false ceiling according to the invention with a folded cassette,
  • 2 is a side view of a support profile with a partially folded cassette,
  • Fig. 3 is an end view of the cassette with a view of the end flange, which has hook-in projections for interacting with support flanges on the support profiles, and on an enlarged scale
  • Fig. 4 shows the detail marked by a circle in Fig. 3, in particular the locking of the retaining flange on the support profile and the formation of the hanging projection on the end flange of the cassette.

Eine im Ganzen mit 1 bezeichnete, in Fig. 1 in einem Aus­schnitt dargestellte Unterdecke ist im wesentlichen ge­bildet durch abgehängte Tragprofile 2, die in den Fig. 2 bis 4 besser dargestellt sind. An diesen Tragprofilen 2 sind viereckige Kassetten 3 befestigt, die an ihrem den Tragprofilen 2 zugewandten und in Gebrauchsstellung dazu parallel verlaufenden Rändern hochstehende Halteflansche 4 mit Raststellen 5, insbesondere eingeprägten Rastnasen 5 haben. Die Tragprofile 2 weisen jeweils eine in ihre Längs­richtung verlaufende, nach unten offene und sich an ihrem Eintritt verengende Rastfuge 6 auf, was man besonders deut­lich auch im Zusammenwirken mit dem Rastvorsprung 5 des Halteflansches 4 in Fig. 4 erkennt.An overall ceiling designated 1, shown in a detail in FIG. 1, is essentially formed by suspended support profiles 2, which are better shown in FIGS. 2 to 4. On these support profiles 2 square cassettes 3 are attached, which on their side facing the support profiles 2 and in the use position parallel upstanding edges have upstanding retaining flanges 4 with locking points 5, in particular impressed locking lugs 5. The support profiles 2 each have a locking joint 6 which runs in their longitudinal direction, is open at the bottom and narrows at their entry, which can also be seen particularly clearly in cooperation with the locking projection 5 of the holding flange 4 in FIG. 4.

Zumindest einzelne Kassetten 3 sind zusätzlich zu ihrer Verrastung mittels einer im folgenden noch näher zu be­schreibenden Schwenklagerung abklappbar, wie es in den Fig. 1 und 2 angedeutet ist. Durch das Abklappen der Kas­sette 3 kann eine Montageöffnung 7 an der Unterdecke 1 frei­gegeben werden, um oberhalb dieser Unterdecke 1 verlaufen­de Installation inspizieren oder reparieren zu können. Die abgeklappte Kassette 3 hängt dann mittels ihrer Schwenk­lagerung an zwei parallelen Tragprofilen 2.At least individual cassettes 3 can be folded down in addition to their latching by means of a pivot bearing to be described in more detail below, as is indicated in FIGS. 1 and 2. When the cassette 3 is folded down, an assembly opening 7 on the suspended ceiling 1 can be opened in order to be able to inspect or repair the installation running above this suspended ceiling 1. The folded cassette 3 then hangs on two parallel support profiles 2 by means of its pivot bearing.

Die Ausbildung des Schwenklagers der Kassette 3 ist eben­falls vor allem anhand der Fig. 4 zu erkennen. Dabei wird auch deutlich, daß die Kassette 3 im Bereich ihres Schwenk­lagers einen rechtwinklig zum Tragprofil 2 verlaufenden hochstehenden Endflansch 8 hat. An beiden Enden hat dieser Endflansch 8 gemäß Fig. 3 einen Ausschnitt 9, der zu den Tragprofilen 2 hin jeweils offen ist.The formation of the pivot bearing of the cassette 3 can also be seen above all from FIG. 4. It is also clear that the cassette 3 has in the region of its pivot bearing a vertical end flange 8 extending at right angles to the support profile 2. 3 has a cutout 9 at both ends, which is open towards the support profiles 2.

In Fig. 4 erkennt man nun vor allem, daß der Endflansch 8 im Bereich seines von der Kassettenoberfläche 10 abge­wandten Randes 11 jeweils einen gegen das Tragprofil 2 hin über den Ausschnitt 9 tragenden, einstückig angebrachten Vorsprung 12 hat. Das Tragprofil 2 hat seitlich seiner Rastfuge 6 am unteren Rand zur Mitte der Kassette 3 hin­weisende Tragflansche 13 und die Ausschnitte 9 übergreifen in Gebrauchsstellung mittels der Vorsprünge 12 diese Trag­flansche 13. Man erkennt schon in Fig. 4, daß der Vorsprung 12 bis über einen Tragflansch 13 ragt. Dadurch ist deut­lich, daß beim Ausrasten des Halteflansches 4 und dem da­raus resultierenden teilweisen Absenken der Kassette 3 der Vorsprung 12 auf dem Tragflansch 13 des Tragprofiles 2 zu liegen kommt. Somit kann die Kassette um die so gebildete Schwenklagerung zwischen Vorsprung 12 und Tragflansch 13 abgeklappt werden. Zusätzlich kann sie aber in vorteil­hafter Weise auch in Längsrichtung des Tragprofiles 2 und seiner Tragflansche 13 verschoben werden, so daß sie beim Abklappen von der Nachbarkassette soweit abdrücken kann, daß das Abklappen problemlos und ungestört durchgeführt werden kann.4, it can be seen above all that the end flange 8 in the region of its edge 11 facing away from the cassette surface 10 each has a protrusion 12 which is integrally attached to the support profile 2 and supports the cutout 9. The support profile 2 has laterally its locking joint 6 at the lower edge toward the center of the cassette 3 supporting flanges 13 and the cutouts 9 overlap these supporting flanges 13 in the use position by means of the projections 12. It can already be seen in FIG. 4 that the projection 12 protrudes over a support flange 13. This makes it clear that when the retaining flange 4 is disengaged and the resulting partial lowering of the cassette 3, the projection 12 comes to rest on the supporting flange 13 of the supporting profile 2. Thus, the cassette can be folded down around the pivot bearing formed in this way between the projection 12 and the support flange 13. In addition, it can also be moved in an advantageous manner in the longitudinal direction of the support profile 2 and its support flanges 13, so that when they are folded down from the adjacent cassette they can be pressed so far that the folding can be carried out without problems and undisturbed.

In Fig. 4 erkennt man ferner, daß der Tragflansch 13 des Tragprofiles 2 an seinem freien Rand einen nach oben stehenden Randsteg 14 hat und der Vorsprung 12 an dem Aus­schnitt 9 des Endflansches 8 eine Hakenform mit einem in Gebrauchsstellung nach unten weisenden Endstück 15 hat. Somit ergibt sich beim Absenken des Vorsprunges 12 auf den Tragflansch 13 durch den hochstehenden Rand 14 und dieses Endstück 15 Formschluß, der ein Abrutschen des Vorsprunges 12 von dem Tragflansch beim Abklappen verhindert. Zusätz­lich kann dieser Vorsprung 15 noch etwas aus der Zeichen­ebene nach vorne gebogen sein, so daß auch bei abgeklappter Kassette dieser Formschluß erhalten bleibt, so daß die er­findungsgemäße einstückige Schwenklagerung besonders gut und sicher gehandhabt werden kann.In Fig. 4 it can also be seen that the support flange 13 of the support profile 2 has at its free edge an upstanding web 14 and the projection 12 on the cutout 9 of the end flange 8 has a hook shape with an end piece 15 pointing downwards in the use position. Thus, when the projection 12 is lowered onto the support flange 13 by the upstanding edge 14 and this end piece 15, there is a positive fit, which prevents the projection 12 from slipping off the support flange when it is folded down. In addition, this projection 15 can also be bent slightly forward from the plane of the drawing, so that this positive locking is retained even when the cassette is folded down, so that the one-piece pivot bearing according to the invention can be handled particularly well and safely.

In Fig. 4 wird ferner deutlich, daß die seitliche Aus­dehnung des Vorsprunges 12 bis nahe an die Ebene reicht, in welcher der parallel zum Tragprofilverkauf orientierte Halteflansch 4 angeordnet ist. Daraus ergibt sich dann von selbst, daß der Vorsprung 12 über den Tragflansch 13 zu­gegen kommt und beim Absenken von selbst auf diesem auf­liegen wird.In Fig. 4 it is also clear that the lateral extension of the projection 12 extends close to the plane in which the holding flange 4 is arranged parallel to the support profile sale. It then follows automatically that the projection 12 comes across the support flange 13 and will automatically rest on it when it is lowered.

In Fig. 2 erkennt man, daß der Endbereich der Halteflansche 4 nahe dem Einhängeausschnitt 9 mit Vorsprung 12 eben­falls einen Ausschnitt 16 hat, so daß in Längsrichtung des Halteflansches 4 zwischen dem Vorsprung 12 und der Ober­seite des Halteflansches 4 ein Einhängezwischenraum für die Kassette 3 frei bleibt. In Fig. 2 ist angedeutet, daß bei einer bestimmten Schräglage der Flansch 4 aufgrund des Ausschnittes 16 noch nicht seitlich mit dem Tragprofil 2 und dessen Einhängeflnasch 13 kollidieren kann, so daß in dieser Lage der Vorsprung 12 bequem über diesen Trag­flansch 13 gebracht werden kann, wenn die Kassette bei der Montage eingehängt oder bei irgendeiner Demontage ausge­hängt werden soll.In Fig. 2 it can be seen that the end region of the holding flanges 4 near the hanging cutout 9 with projection 12 also has a cutout 16, so that in the longitudinal direction of the holding flange 4 between the projection 12 and the top of the holding flange 4 there is a free space for the cassette 3 remains. In Fig. 2 it is indicated that at a certain inclined position, the flange 4 cannot yet collide laterally with the support profile 2 and its suspension clip 13 due to the cutout 16, so that in this position the projection 12 can be conveniently brought over this support flange 13, if the cassette is to be mounted during assembly or to be removed during any disassembly.

Die Kassette 3 kann z. B. aus Blech geformt sein, so daß ihre Randflansche 4 und 8 hochgebogen und die Ausschnitte 9 und 16 und der Vorsprung 12 ausgestanzt sein können. Somit kann in wenigen Arbeitsgängen eine einstückige Kassette 3 gefertigt werden, die dennoch ein Abschwenken erlaubt, ohne daß zusätzliche Endstücke od. dgl. Einzel­teile angefertigt und montiert werden müssen.The cassette 3 can e.g. B. be formed from sheet metal so that its edge flanges 4 and 8 bent up and the cutouts 9 and 16 and the projection 12 can be punched out. Thus, a one-piece cassette 3 can be manufactured in a few work steps, which nevertheless allows pivoting without additional end pieces or the like. Individual parts have to be manufactured and assembled.

In Fig. 4 ist dargestellt, daß der Ausschnitt 9 an dem rechtwinklig zum Tragprofil 2 verlaufenden Endflansch 8 der Kassette 3 auf der dem Halteflansch 4 zugewandten Seite unterhalb des Einhängevorsprunges 12 seitlich offen ist und an der dieser Öffnung 17 gegenüberliegenden Seite eine zum Rand 11 des Flansches 8 hin laufende Begrenzung 18 hat, von welcher der Einhängevorsprung 12 gegen das Tragprofil 2 hin vorsteht. Somit kann in Gebrauchsstellung der Trag­flansch 13 des Halteprofiles 2 in diese seitliche Öffnung 17 ragen, wodurch sichergestellt ist, daß beim Abklappen und Absenken der Vorsprung 12 auf diesem Tragflansch 13 zu liegen kommt und mit diesem zusammen das Schwenklager für die abklappbare Kassette bilden kann.In Fig. 4 it is shown that the cutout 9 on the end flange 8 of the cassette 3, which runs at right angles to the support profile 2, is open laterally on the side facing the holding flange 4 below the hook-in projection 12 and on the side opposite this opening 17 to the edge 11 of the Has flange 8 outward boundary 18, from which the hanging projection 12 protrudes against the support profile 2. Thus, in the position of use, the support flange 13 of the holding profile 2 can protrude into this lateral opening 17, which ensures that when the projection 12 is folded down and lowered, it comes to rest on this support flange 13 and together with it can form the pivot bearing for the foldable cassette.

Für die vorerwähnte einfache Herstellung ist es dabei vor­teilhaft, daß die Oberseite des Einhängevorsprunges 12 bündig mit dem oberen Rand 11 des Endflansches 8 ist. Prak­tisch ist der Vorsprung 12 eine Fortsetzung des Endflansches 8 und entsteht eigentlich dadurch, daß unterhalb des Vor­sprunges 12 in den Flansch 8 die Ausnehmung bzw. der Aus­schnitt 9 angebracht wird.For the aforementioned simple manufacture, it is advantageous that the top of the hanging projection 12 is flush with the upper edge 11 of the end flange 8. In practice, the projection 12 is a continuation of the end flange 8 and actually arises from the fact that the recess or the cutout 9 is made below the projection 12 in the flange 8.

Eine weitere Ausgestaltung der Erfindung zur Verbesserung der Halterung der abgeklappten Kassette könnte noch darin bestehen, daß seitlich des Endstückes 15 eine nicht näher dargestellte Sicke rechtwinklig zum Rand 11 des Flansches 8 verläuft, in welche der hochstehende Rand 14 bei abge­klappter Kassette formschlüssig eingreifen kann.A further embodiment of the invention to improve the holder of the folded cassette could still consist in the fact that a bead (not shown in detail) extends at the side of the end piece 15 at right angles to the edge 11 of the flange 8, into which the upstanding edge 14 can engage in a positive manner when the cassette is folded down.

Alle in der Beschreibung, den Zusammenfassung, den An­sprüchen und der Zeichnung dargestellten Merkmalen und Konstruktionsdetails können sowohl einzeln als auch in beliebiger Kombination miteinander wesentliche Bedeutung haben.All features and construction details shown in the description, the summary, the claims and the drawing can have significant meaning both individually and in any combination with one another.
