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 locking joint on its underside, so that the upstanding retaining flanges of the cassettes can be locked in position in use.

Bei einer bekannten Unterdecke dieser Art (siehe z.B. in der AT-B 368 786) 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 (see e.g. in AT-B 368 786), 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 foldable 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 und 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 Flansches (4) ein Einhängezwischenraum für die Kassette (3) frei bleibt. Wird die Rastverbindung der Halteflansche an den Rastfugen der Tragprofile gelöst, gelangt durch das Abklappen der Kassette jeder der an den Endflanschen befindlichen Vorsprüngen 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 and 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 flange (4), a space for hanging the cassette (3) remains free. If the locking connection of the holding flanges is released at the locking joints of the support profiles, each of the projections located on the end flanges on the upper side of the support flange of the support profile passes through the folding of the cassette, so that the cassette then hangs positively on it, but advantageously also in the direction of Carrier profile is displaceable. 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 gemäß Anspruch 1 vorgesehen, daß 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 provided according to claim 1 that the end region of the Retaining flanges near the insertion cut-out with a projection also have a cutout, so that in the longitudinal direction of the retaining flange between the projection and the top of the retaining flange, an insertion space remains free for the cassette.

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 cut-out with a relatively narrow entry together with the hook-in projection, which, however, expands inside is so that it allows the desired pivoting movements and yet can 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 Befestigen 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 allows the cassette to be securely and firmly attached in the use position, but also allows it to be simply folded down without the danger of the entire cassette being released from the support profiles would result, 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 teilweise 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 vergrößertem 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. Square cassettes 3 are fastened to these supporting profiles 2 and have upstanding holding flanges 4 with locking points 5, in particular stamped-in locking lugs 5, on their edges facing the supporting profiles 2 and parallel to them in the position of use. 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-down 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 and supports the support profile 2 via the cutout 9. The support profile 2 has laterally its locking joint 6 on 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 extends over a supporting flange 13 protrudes. 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 thus formed 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 push so far that the folding can be carried out easily 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 Tragprofilverlauf 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 profile of the supporting profile. 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 Einhängeflansch 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 the flange 4 at a certain inclined position because of the cutout 16 can not yet collide laterally with the support profile 2 and its mounting flange 13, so that in this position the projection 12 can be conveniently brought over this mounting 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 Offnung 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 raised edge 14 can engage in a form-fitting 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.
