Description

Der Gegenstand der Erfindung betrifft eine Halteplatte aus Kunststoff oder dergl. an einem Staubsaugerfilterbeutel, wobei die Halteplatte eine Öffnung für den Sauganschlußstutzen des Staubsaugers aufweist und für den Saugbetrieb mit dem Staubsaugerfilterbeutel in eine Plattenaufnahme des Staubsaugers formschlüssig einsteckbar ist.The object of the invention relates to a holding plate made of plastic or the like. On a vacuum cleaner filter bag, the holding plate having an opening for the suction connection piece of the vacuum cleaner and for the suction operation with the vacuum cleaner filter bag can be positively inserted into a plate holder of the vacuum cleaner.

Eine derartige Halteplatte ist aus der DE-A-2 116 579 bekannt.Such a holding plate is known from DE-A-2 116 579.

Bei einer älteren Halteplatte gemäß DE-A-3 403 135 ist zur staubdichten Verbindung der den Filterbeutel tragenden Halteplatte mit dem Sauganschlußstutzen des Staubsaugers die öffnung für den Sauganschlußstutzen von einem elastischen Dichtring umgeben, wobei die Platte außerhalb des Dichtringes äußerst biegesteif ist. Die Halteplatte ist in eine zugeordnete Plattenaufnahme des Staubsaugers formschlüssig eingesteckt. Um ein dichtes Anliegen der Halteplatte mit dem Sauganschlußstutzen bzw. dessen Einsaugöffnung zu erreichen, besitzt die Plattenaufnahme ober- und unterseitig u-förmige Führungsnuten, die unterschiedliche Tiefen aufweisen. Den Führungsnuten mit der größeren Tiefe sind mindestens ein Federelement zugeordnet, welches die Halteplatte nach dem Einstecken in die Plattenaufnahme dicht gegen den Grund der anderen Führungsnut drückt, wobei sich der Dichtring gegen die Plattenaufnahme abstützt und die Dichtwirkung in axialer Richtung erzielt. Für die Federelemente sind an der Halteplatte entsprechende Ein- oder Ausschnitte vorgesehen, die in unmittelbarer Nähe des seitlichen Randes der Platte liegen. Der Einsatz von Federelementen zur Erzielung einer Dichtwirkung zwischen der Halteplatte und dem Sauganschlußstutzen des Staubsaugers bedeutet einen erheblichen konstruktiven Aufwand. Außerdem ist beim Einsetzen des Staubfilterbeutels besondere Aufmerksamkeit geboten.In an older holding plate according to DE-A-3 403 135, the opening for the suction connecting piece is surrounded by an elastic sealing ring for the dust-tight connection of the holding plate carrying the filter bag to the suction connection piece of the vacuum cleaner, the plate outside the sealing ring being extremely rigid. The holding plate is positively inserted into an associated plate receptacle of the vacuum cleaner. In order to achieve a tight fit of the holding plate with the suction connection piece or its suction opening, the plate receptacle has U-shaped guide grooves on the top and bottom sides, which have different depths. The guide grooves with the greater depth are assigned at least one spring element, which presses the holding plate tightly against the base of the other guide groove after insertion into the plate holder, the sealing ring being supported against the plate holder and achieving the sealing effect in the axial direction. For the spring elements, corresponding incisions or cutouts are provided on the holding plate, which lie in the immediate vicinity of the lateral edge of the plate. The use of spring elements to achieve a sealing effect between the holding plate and the suction connection piece of the vacuum cleaner means a considerable design effort. In addition, special attention is required when inserting the dust filter bag.

Bei sehr vielen derzeit auf dem Markt befindlichen Staubsaugertypen nimmt jedoch der den Staubbeutelsammelraum verschließende und schwenkbar am Staubsaugergehäuse angelenkte Deckel zugleich dem Sauganschlußstutzen des Staubsaugers auf, während die Halteplatte separat hiervon mit dem Staubsaugerfilterbeutel in einer ggf. schwenkbar im Staubsammelraum gelagerten Plattenaufnahme formschlüssig eingesteckt ist. Bei diesen Staubsaugern erfolgt die Verbindung zwischen dem Sauganschlußstutzen und der Halteplatte selbsttätig beim Schließen des Deckels. Wird der Deckel geschlossen, so schwenkt der Sauganschlußstutzen ggf. zentrierend in die Öffnung der Halteplatte ein. Die geforderte Abdichtung zwischen der Halteplatte und dem Sauganschlußstutzen bewerkstelligt dabei ein den Sauganschlußstutzen umgebender Dichtansatz am Deckel des Staubsaugers, welcher bei geschlossenem Deckel die Einlaßöffnung an der Halteplattenoberseite ringförmig umgreift und in Auflage damit steht. Bei diesen Staubsaugern ist es auch üblich, den Sauganschlußstutzen am Dichtansatz enden zu lassen, so daß der Stutzen nicht in die Öffnung der Halteplatte eingreifen kann.In the case of many types of vacuum cleaner currently on the market, however, the cover which closes the dust bag collecting space and which is pivotably hinged to the vacuum cleaner housing also accommodates the suction connection piece of the vacuum cleaner, while the holding plate is inserted in a form-fitting manner with the vacuum cleaner filter bag in a plate receptacle which may be pivoted in the dust collecting space. In these vacuum cleaners, the connection between the suction connection piece and the holding plate takes place automatically when the lid is closed. If the lid is closed, the suction connection piece swivels centering into the opening of the holding plate, if necessary. The required seal between the holding plate and the suction connection piece accomplishes a sealing approach surrounding the suction connection piece on the cover of the vacuum cleaner, which, when the cover is closed, encompasses the inlet opening on the upper side of the holding plate in a ring and is in contact therewith. With these vacuum cleaners, it is also common to let the suction connection piece end at the sealing attachment, so that the piece cannot engage in the opening of the holding plate.

Die bekannte Halteplatte kann für die letztgenannten Staubsaugertypen zu Problemen führen. Infolge der sich beim Schließen des Staubraumdeckels ergebenden Relativbewegungen zwischen der Halteplatte und dem Sauganschluß im Deckel, die eine genaue Zentrierung der miteinander zu verbindenden Teile erforderlich machen, sind sehr enge Maßtoleranzen sowohl bei der Halteplatte als auch bei den sonstigen mit dem Staubfilterbeutel in Wirkverbindung stehenden Funktionsteilen, wie Deckellagerung, Anordnung des Sauganschlußstutzens am Deckel oder dergl. einzuhalten, damit bei geschlossenem Deckel die optimale Dichtwirkung erzielt wird. Voraussetzung hierfür ist jedoch, daß ein gleichmäßiger Anpreßdruck in der Randzone der Öffnung auf der Halteplatte zwischen dem Sauganschluß und der Halteplatte erreicht wird. Dies ist aber z.B. schon bei leicht gewölbten Halteplatten, oder bei Halteplatten, die entsprechend dem bekannten Technikstand (DE-OS-3 403 135) mittels Federkraft lagefest und in axialer Richtung nicht bewegbar in den Plattenaufnahmen festgesetzt sind, nicht mehr gegeben, da sich das biegesteife Plattenmaterial im Bereich der Öffnung für den Sauganschluß den Formänderungen bzw. Plattenverwerfungen nicht selbständig anpassen kann. Die Verbindung zwischen dem Sauganschluß und der mit diesem bei geschlossenem Staubraumdeckel in Berührung stehenden Halteplate kann undicht werden, da ein ungleichmäßig verteilter Anpreßdruck herrscht. Dieser Nachteil tritt ebenfalls ein, wenn sich z.B. durch Unregelmäßigkeiten im Plattenmaterial unterschiedliche Plattenstärken ergeben. Somit kann ungefilterte, staubbeladene Luft in den Motorgebläseraum gelangen, mit den Folgen, daß der Gebläsemotor u. Umständen beschädigt oder gar zerstört wird. Ebenso kann eine Undichtheit zwischen dem Sauganschluß und der mit diesem bei geschlossen Deckel in Anlage gebrachten Halteplatte auch eintretten, wenn die Plattenaufnahme bzw. die Halteplatte selbst nicht lagerichtig im Staubsauger eingesetzt ist. Ist beispielsweise der Schwenkweg der Plattenaufnahme zu gering, so verbleibt ein keilförmiger Spalt zwischen der Halteplattenoberfläche und dem zugeordneten Dichtansatz am Sauganschluß, durch den ebenfalls ein staubbeladener den Staubsaugerfilterbeutel umgehender Saugluftstrom mit entsprechend nachteiliger Wirkung entsteht.The known holding plate can lead to problems for the latter types of vacuum cleaner. As a result of the relative movements between the holding plate and the suction connection in the lid which occur when the dust chamber lid is closed, which necessitate precise centering of the parts to be connected to one another, there are very narrow dimensional tolerances both for the holding plate and for the other functional parts which are operatively connected to the dust filter bag , such as lid storage, arrangement of the suction connector on the lid or the like. To ensure that the optimum sealing effect is achieved when the lid is closed. The prerequisite for this, however, is that a uniform contact pressure is achieved in the edge zone of the opening on the holding plate between the suction connection and the holding plate. But this is e.g. even with slightly arched holding plates, or with holding plates that are fixed in position by spring force according to the known state of the art (DE-OS-3 403 135) and cannot be moved in the axial direction in the plate receptacles, since the rigid plate material is in the area the opening for the suction connection can not adapt to changes in shape or plate warping independently. The connection between the suction connection and the holding plate which is in contact with it when the dust chamber cover is closed can become leaky, since there is an unevenly distributed contact pressure. This disadvantage also occurs if e.g. irregularities in the plate material result in different plate thicknesses. Thus, unfiltered, dust-laden air can get into the engine blower compartment, with the result that the blower motor u. Is damaged or even destroyed. Likewise, a leak between the suction connection and the holding plate brought into contact with it when the cover is closed can also occur if the plate holder or the holding plate itself is not inserted in the correct position in the vacuum cleaner. If, for example, the swivel path of the plate holder is too small, a wedge-shaped gap remains between the holding plate surface and the associated sealing attachment on the suction connection, which likewise creates a dust-laden suction air flow that bypasses the vacuum cleaner filter bag with a correspondingly disadvantageous effect.

Der Erfindung liegt somit die Aufgabe zugrunde, eine biegesteife Halteplatte der eingangs genannten Art so auszubilden, daß sie im Bereich der Öffnung für den Sauganschluß elastischer wird und daß auch bei abweichenden Maßtoleranzen der mit dem Staubsaugerfilterbeutel in Wirkverbindung stehenden Funktionsteile sowie bei Unregelmäßigkeiten im Plattenmaterial oder auf der Oberfläche der Halteplatte selbst eine optimale Staubabdichtung zwischen dem Sauganschluß des Staubsaugers und der Halteplatte erreicht wird.The invention is therefore based on the object to form a rigid holding plate of the type mentioned in such a way that it becomes more elastic in the area of the opening for the suction connection and that even in the case of deviating dimensional tolerances of the functional parts which are operatively connected to the vacuum cleaner filter bag and in the event of irregularities in the plate material or the surface of the holding plate itself optimal dust seal between the suction connection of the vacuum cleaner and the holding plate is achieved.

Die gestellte Aufgabe wird erfindungsgemäß gelöst durch die Merkmale des Anspruches 1.The object is achieved according to the invention by the features of claim 1.

Vorteilhafte Ausgestaltungen gehen aus den Unteransprüchen hervor.Advantageous configurations emerge from the subclaims.

Die mit der Erfindung erzielten Vorteile sind insbesondere darin zu sehen, daß sich die Halteplatte in der Plattenaufnahme des Staubsaugers beim Schließen des Staubraumdeckels schon bei der ersten Berührung mit dem Sauganschluß selbsttätig den auf sie wirkenden Belastungen anpaßt und bei geschlossenem Deckel absolut dicht mit dem rundum gleichmäßig belasteten Sauganschluß abschließt. Durch die besondere Anordnung der Elastizitätszonen durch die Wahl der begrenzenden Plattenausschnitt auf der Halteplatte ist gewährleistet, daß keine engen Maßtoleranzen zwischen den Funktionsteilen eingehalten werden müssen. Trotz des biegesteifen Plattenmaterials wird erreicht, daß die Halteplatte selbstdichtend wirkt, weil die Dichtwirkung zwischen der erfindungsgemäß sehr elastischen Halteplattenfläche im Bereich der Öffnung und dem darüberliegenden Sauganschluß erzielt wird.The advantages achieved by the invention can be seen in particular in the fact that the holding plate in the plate receptacle of the vacuum cleaner automatically adapts to the stresses acting on it when the dust chamber cover is first touched, and when the cover is closed it is absolutely tight with all around loads the suction connection. The special arrangement of the elastic zones by the choice of the limiting plate cutout on the holding plate ensures that no tight dimensional tolerances between the functional parts have to be observed. Despite the rigid plate material, it is achieved that the holding plate acts self-sealing because the sealing effect between the very elastic holding plate surface according to the invention is achieved in the area of the opening and the suction connection above it.

Durch die Erfindung werden Zonen unterschiedlicher Elastizität auf der Halteplatte ohne Änderung der Werkstoffkomponenten bzw. ohne Änderung der Materialstärke geschaffen. Die Plattenausschnitte, welche die Elastizitätszonen begrenzen sind werkzeugmäßig einfach zu realisieren und stellen z.B. bei aus thermoplastischem Kunststoff gefertigten Halteplatten keinerlei Probleme beim Spritzen dar. Ferner wird durch die Verwendung von Plattenausschnitten wesentlich weniger Material zur Plattenherstellung benötigt als bisher, so daß die Halteplatten auch kostengüngstiger werden.The invention creates zones of different elasticity on the holding plate without changing the material components or without changing the material thickness. The panel cutouts that limit the elasticity zones are easy to implement using tools and provide e.g. in the case of holding plates made of thermoplastic plastic, there are no problems with spraying. Furthermore, the use of plate cutouts means that much less material is required for plate production than before, so that the holding plates are also less expensive.

Bei dem Fig. 1 dargestellten Staubsauger 1 vom Typ eines Bodenstaubsaugers ist bei geöffnetem Staubraumdeckel 2, welcher am Staubsaugergehäuse schwenkbar angelenkt ist, der Staubsammelraum 3 zugänglich. Der Staubsammelraum 3 dient zur Aufnahme des Staubsaugerfilterbeutels 4.In the vacuum cleaner 1 shown in FIG. 1 of the type of a floor vacuum cleaner, the dust collecting space 3 is accessible when the dust chamber cover 2 is open, which is pivotably articulated on the vacuum cleaner housing. The dust collecting space 3 serves to hold the vacuum cleaner filter bag 4.

Der Staubsaugerfilterbeutel 4 ist über eine vorzugsweise aus einem thermoplastischen Kunststoff bestehende biegesteife Halteplatte 5 in einer Plattenaufnahme 6 im Staubsammelraum 3 lösbar befestigt. Die Verbindung zwischen der Halteplatte 5 und dem Staubsaugerfilterbeutel 4 kann beispielsweise über eine Klebeverbindung oder auch über eine Schweißverbindung hergestellt werden. Hierzu weist die Halteplatte eine kreisförmige Befestigungszone 7 (Fig. 2 u. 3) auf.The vacuum cleaner filter bag 4 is detachably fastened in a plate receptacle 6 in the dust collecting space 3 via a rigid holding plate 5 preferably made of a thermoplastic plastic. The connection between the holding plate 5 and the vacuum cleaner filter bag 4 can be established, for example, via an adhesive connection or also via a welded connection. For this purpose, the holding plate has a circular fastening zone 7 (FIGS. 2 and 3).

Die Halteplatte 5 ist in bekannter Weise formschlüssig in die Plattenaufnahme 6 einzustecken, welche dann den unteren sowie jeweils einen seitlichen Begrenzungsgrand 8 (Fig. 2) der Halteplatte 5 nach Art einer anschlagbegrenzten Führung umgreift. Die Plattenaufnahme 6 selbst ist anschlagbegrenzt schwenkbar im Staubsaugergehäuse gelagert.The holding plate 5 is to be positively inserted into the plate receptacle 6 in a known manner, which then engages around the lower and one lateral boundary 8 (FIG. 2) of the holding plate 5 in the manner of a stop-limited guide. The plate receptacle 6 itself is pivotally limited in the vacuum cleaner housing.

Die Halteplatte 5 weist mittig eine Öffnung 9 mit einer umlaufenden Dichtlippe 10 für einen im Staubraumdeckel 2 angeordneten Sauganschlußstutzen 11 auf, dessen Öffnung von einem Dichtansatz 12 für die Halteplatte 5 in ebenfalls bekannter Weise umgeben ist.The holding plate 5 has an opening 9 in the middle with a circumferential sealing lip 10 for a suction connection piece 11 arranged in the dust chamber cover 2, the opening of which is surrounded by a sealing attachment 12 for the holding plate 5 in a likewise known manner.

Die Anordnung des Sauganschlußstutzens 11 im Staubraumdeckel 2 ist so gewählt, daß bei geschlossenem Staubraumdeckel 2 die Öffnung 9 in der eingesteckten Halteplatte 5 deckungsgleich der Sauganschlußstutzenöffnung gegenübersteht, wobei die Dichtwirkung zwischen dem Sauganschlußstuzen 11 und der Halteplatte durch den Anpreßdruck des Deckels bzw. des Dichtansatzes 12 des Sauganschlußstutzens 11 auf die Halteplatte 5 erzielt wird.The arrangement of the suction connection piece 11 in the dust chamber cover 2 is selected so that when the dust chamber cover 2 is closed, the opening 9 in the inserted holding plate 5 is congruent with the suction connection piece opening, the sealing effect between the suction connection piece 11 and the holding plate being caused by the contact pressure of the cover or the sealing attachment 12 of the suction connector 11 is achieved on the holding plate 5.

Um zu gewährleisten, daß diese Verbindung bei geschlossenem Staubraumdeckel 2 absolut staubdicht hergestellt wird, weist die Halteplatte 5 im biegesteifen Plattenmaterial ein oder mehrere Plattenausschnitte 13 auf. Die Plattenausschnitte 13, welche das zwischen den Ausschnitten und der Öffnung 9 befindliche Plattenmaterial elastischer gestalten, sind dabei auf der Halteplatte 5 außerhalb der Befestigungszone 7 zwischen der Öffnung 9 für der Sauganschlußstutzen 11 und mindestens einem Begrenzungsrand 8 der Halteplatte 5 angeordnet. Durch diese Plattenausschnitte 13 wird die biegesteife Halteplatte 5 im Plattenbereich um die Öffnung 9 herum wesentlich elastischer als die übrige Plattenfläche, so daß der Öffnungsbereich der Halteplatte 5 bei geschlossenem Staubraumdeckel 2 und unterstützt durch einem gleichmäßig im Öffnungsbereich wirkenden Anpreßdruck des Sauganschlußstutzens 11 bzw. des Dichtansatzes 12 selbstdichtend mit dem Sauganschluß in Wirkverbindung tritt. Hierdurch werden Undichtheiten oder Nebenluftwege vollkommen ausgeschaltet. Die konzentrisch zur Öffnung 9 auf der Halteplatte 5 angeordnete Dichtlippe 10 unterstützt dabei die Dichtwirkung zusätzlich.In order to ensure that this connection is made absolutely dust-tight when the dust chamber cover 2 is closed, the holding plate 5 has one or more plate cutouts 13 in the rigid plate material. The plate cutouts 13, which make the plate material between the cutouts and the opening 9 more elastic, are arranged on the holding plate 5 outside the fastening zone 7 between the opening 9 for the suction connecting piece 11 and at least one boundary edge 8 of the holding plate 5. By means of these plate cutouts 13, the rigid holding plate 5 in the plate area around the opening 9 is substantially more elastic than the rest of the plate surface, so that the opening area of the holding plate 5 when the dust chamber cover 2 is closed and is supported by a contact pressure of the suction connection piece 11 or the sealing attachment which acts uniformly in the opening area 12 self-sealingly engages with the suction connection. This completely eliminates leaks or secondary airways. The sealing lip 10 arranged concentrically to the opening 9 on the holding plate 5 additionally supports the sealing effect.

Nach der Erfindung sind numehr mehrere Varianten bezüglich der Ausbildung und Anordnung der Plattenausschnitte 13 möglich.According to the invention, only a number of variants are possible with regard to the design and arrangement of the plate cutouts 13.

Nach Fig. 2 ist beispielsweise eine Ausführung gewählt (siehe auch Fig. 3), bei der die Plattenausschnitte 13 gradlinig verlaufend auf der Halteplatte 5 angeordnet sind und jeweils am unteren Begrenzungsrand 8 der Halteplatte 5 in Platteneinsteckrichtung gesehen offen enden. Die Abbildung zeigt dabei zwei Plattenausschnitte 13 beiderseits der Öffnung 9 für den Sauganschlußstutzen 11, denen zweckmäßigerweise in der Plattenaufnahme 6 (Fig. 8) des Staubsaugers 1 angepaßte Gegenstücke 14 in Form von Stegen oder dergl. zugeordnet sind. Bei dem hier gezeigten Ausführungsbeispiel bewirken die z.B. angeformten Gegenstücke 14 eine vorteilhafte Versteifung der Plattenaufnahme 6, insbesondere eine Verstärkung der Halteplatten-Führungen dieser Plattenaufnahme.According to Fig. 2, for example, an embodiment is selected (see also Fig. 3) in which the plates Cutouts 13 are arranged in a straight line on the holding plate 5 and each open at the lower boundary edge 8 of the holding plate 5 seen in the plate insertion direction. The figure shows two plate cutouts 13 on both sides of the opening 9 for the suction connection piece 11, which are suitably assigned counterparts 14 in the form of webs or the like in the plate receptacle 6 (FIG. 8) of the vacuum cleaner 1. In the embodiment shown here, the counterparts 14, for example molded on, bring about an advantageous stiffening of the plate holder 6, in particular a reinforcement of the holding plate guides of this plate holder.

Die Ausführung der Halteplatte 5 entsprechend Fig. 2 ist schon in vielen Fällen ausreichend, um der Platte die erforderliche Elastizität zu geben. Insbesondere ist die gewählte Anordnung der Plattenausschnitte 13 sehr gut geeignet, die Fluchtungsfehler in der Schwenkebene des Staubraumdeckels 2 zwischen der Halteplatte 5 und dem Deckel mit den Sauganschlußstutzen 11 zu kompensieren.2 is sufficient in many cases to give the plate the required elasticity. In particular, the selected arrangement of the plate cutouts 13 is very well suited to compensate for the misalignment in the pivoting plane of the dust chamber cover 2 between the holding plate 5 and the cover with the suction connection piece 11.

Beim Ausführungsbeispiel gemäß Fig. 4 sind ebenfalls zwei Plattenausschnitte 13 vorgesehen, von denen der eine am oberen Begrenzungsrand 8 und der andere am unterend Begrenzungsrand 8 offen endet. Die Plattenausschnitte 13 verlaufen ebenfalls gerade und sind auf das Zentrum der Öffnung 9 für den Sauganschlußstutzen 11 zentriert.In the exemplary embodiment according to FIG. 4, two plate cutouts 13 are likewise provided, one of which ends openly at the upper boundary edge 8 and the other at the lower boundary edge 8. The plate cutouts 13 also run straight and are centered on the center of the opening 9 for the suction connection piece 11.

In den Fig. 5 bis 7 hingegen sind Halteplatten 5 gezeigt, bei denen die Plattenausschnitte 13 nicht bis direkt an die Plattenränder reichen. Dabei sind entsprechend Fig. 5 jeweils rechts und links der Öffnung 9 Plattenausschnitte 13 und gemäß Fig. 6 diagonal auf der Halteplatte 5 verlaufende Ausschnitte vorgesehen.5 to 7, on the other hand, holding plates 5 are shown, in which the plate cutouts 13 do not extend directly to the plate edges. 5, plate cutouts 13 are provided on the right and left of the opening, and cutouts running diagonally on the holding plate 5 according to FIG. 6.

Nach Fig. 7 sind die durch die Plattenausschnitte 13 begrenzten Elastizitätszonen konzentrisch zur Öffnung des Sauganschlußstutzens 11 vorgesehen.According to FIG. 7, the elastic zones delimited by the plate cutouts 13 are provided concentrically to the opening of the suction connection piece 11.

Wie insbesondere aus Fig. 5 ersichtlich, kann sich die Halteplatte 5 bei fest eingespanntem Begrenzungsrand 8 in der Plattenaufnahme 6 und selbst bei einem Fluchtungsfehler zwischen ihr und der Plattenaufnahme 6 im Bereich der Öffnung 9 dem Sauganschlußstutzen 11 staubdicht anpassen. Dabei herrscht praktisch überall der gleiche Anpreßdruck auf der Plattenoberfläche im Bereich der Öffnung 9, so daß die Staubdichtheit immer gewährleistet ist.As can be seen in particular from FIG. 5, the holding plate 5 can adapt to the suction connector 11 in a dust-tight manner when the boundary edge 8 is firmly clamped in the plate receptacle 6 and even in the event of an alignment error between it and the plate receptacle 6 in the region of the opening 9. The same contact pressure prevails practically everywhere on the plate surface in the area of the opening 9, so that dust-tightness is always guaranteed.

Abweichend von den hier beschriebenen Ausführungsbeispielen sind selbstverständlich weitere Gestaltungsmöglichkeiten der Elastizitätszonen auf der Halteplatte 5 denkbar und möglich. Auch könnte die Halteplatte 5 statt aus Kunststoff aus Pappe gefertigt sein.Deviating from the exemplary embodiments described here, further design options for the elasticity zones on the holding plate 5 are of course conceivable and possible. The holding plate 5 could also be made of cardboard instead of plastic.
