Description

Die Erfindung betrifft eine lösbare Anordnung eines Funktionsteiles in einer Gehäuseöffnung eines Staubsaugergehäuses gemäß dem Oberbegriff des Anspruches 1.The invention relates to a detachable arrangement of a Functional part in a housing opening of a vacuum cleaner housing according to the preamble of claim 1.

Eine solche lösbare Anordnung eines Funktionsteiles an einem Staubsaugergehäuse ist durch die DE-A-43 35 993 bekannt. Bei dieser bekannten Anordnung ist ein das Funktionsteil bildendes eckiges Ausblasgitter in seiner einen Breitenrichtung größer als die lichte Weite einer am Staubsaugergehäuse vorgesehenen Gehäuseöffnung bemessen. Damit kann dieses Ausblasgitter mit seinen beiden entsprechend gegenüberliegenden Randkanten die die Gehäuseöffnung enthaltende Gehäusewand des Staubsaugergehäuses untergreifen. Im Bereich der einen zu untergreifenden Begrenzungskante der Gehäuseöffnung ist ein gesondertes Federelement vorgesehen. Beim Einsetzen des Ausblasgitters in die Gehäuseöffnung wird zunächst die eine Randkante unter die eine Begrenzungskante eingeführt. Dabei trifft die entsprechende Randkante des Ausblasgitters auf das Federelement. Gegen die Federkraft dieses Federelementes wird das Ausblasgitter soweit in die Gehäuseöffnung vorgeschoben, bis seine gegenüberliegende andere Randkante an der der einen Begrenzungskante gegenüberliegenden Begrenzungskante vorbei in die Gehäuseöffnung hineingedrückt werden kann. Durch die Federkraft des Federelementes wird das Ausblasgitter dann entgegen der Einsteckrichtung soweit verschoben, bis die andere Randkante auf ein Anschlagteil trifft. In dieser Stellung untergreifen die beiden Randkanten des Ausblasgitters die entsprechenden Begrenzungskanten der Gehäuseöffnung. Da das Ausblasgitter durch die Federkraft in dieser Stellung gehalten wird, kann es nicht mehr aus der Gehäuseöffnung herausfallen. Such a releasable arrangement of a functional part on a Vacuum cleaner housing is known from DE-A-43 35 993. At this known arrangement is one that forms the functional part square discharge grille in one width direction larger than the clear width of a provided on the vacuum cleaner housing Dimension the housing opening. This can be used for this outlet grille with its two correspondingly opposite Edge edges of the housing wall containing the housing opening Reach in under the vacuum cleaner housing. In the area of one too lower edge of the housing opening is a separate spring element provided. When inserting the outlet grille the first one is in the housing opening Edge inserted under a boundary edge. there meets the corresponding edge of the outlet grille Spring element. Against the spring force of this spring element the outlet grille pushed so far into the housing opening, until its opposite other edge on one Boundary edge opposite boundary edge past can be pressed into the housing opening. Through the The outlet grille then becomes spring force of the spring element moved against the direction of insertion until the other edge meets a stop part. In this Position reach under the two edges of the outlet grille the corresponding boundary edges of the housing opening. Because the outlet grille by the spring force in this Position is held, it can no longer out of the housing opening fall out.

Der Erfindung liegt die Aufgabe zugrunde, eine lösbare Anordnung eines Funktionsteiles der eingangs beschriebenen Art so weiterzubilden, daß es zur sicheren Halterung des Funktionsteiles in der Gehäuseöffnung keines gesonderten Federelementes bedarf.The invention has for its object a releasable arrangement a functional part of the type described above to further develop that it for the secure mounting of the functional part no separate spring element in the housing opening requirement.

Die Lösung der gestellten Aufgabe gelingt durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale. Der federnd ausgebildete Bereich kann bei der Herstellung des Funktionsteiles geschaffen werden, desgleichen der entsprechende Abstützteil. Damit entfallen sowohl der entsprechende Materialaufwand als auch die Herstellungskosten für ein gesondertes Federelement. Außerdem ergeben sich keine zusätzlichen Montagekosten für ein solches gesondertes Federelement.The task is solved by the in the license plate of claim 1 specified features. The bouncy trained area can in the manufacture of the functional part be created, as is the corresponding one Support part. This eliminates both the corresponding Material costs as well as the manufacturing costs for one separate spring element. In addition, there are no additional ones Assembly costs for such a separate spring element.

Sowohl die Federfunktion als auch die Verriegelungsfunktion können dadurch zusammengefaßt werden, daß wechselseitig mindestens an einer Seitenkante des Funktionsteiles und der dieser Seitenkante entsprechenden Begrenzungskante der Gehäuseöffnung einander gegenüberliegend ein eine in Löserichtung des Funktionsteiles geneigte Anlauffläche aufweisender Vorsprung und eine in ihrer Kontur dem Vorsprung entsprechende Vertiefung vorgesehen ist, wobei die Seitenkante und/ oder die Begrenzungskante im Bereich des Vorsprunges bzw. der Vertiefung federnd ausgebildet sind.Both the spring function and the locking function can be summarized in that mutually at least on one side edge of the functional part and the this side edge corresponding boundary edge of the Housing opening opposite one another in the release direction of the functional part inclined contact surface Projection and a contour corresponding to the projection Depression is provided, the side edge and / or the boundary edge in the area of the projection or the Depression are resilient.

Dadurch, daß die Anlauffläche zusätzlich gegenüber der Einfügerichtung des Funktionsteiles in die Gehäuseöffnung keilförmig geneigt ausgebildet ist, wird der Kraftaufwand beim Einführen des Funktionsteiles in die Gehäuseöffnung vermindert.Because the contact surface is also opposite to the insertion direction of the functional part in the housing opening wedge-shaped is inclined, the effort when Inserting the functional part into the housing opening is reduced.

Vorteilhafterweise kann der federnde Bereich auch an mindestens an einem der die Begrenzungskanten untergreifenden Halteelemente vorgesehen sein. Advantageously, the resilient area can also at least on one of the edges under the boundary Holding elements may be provided.

Der sichere Sitz des Funktionsteiles in der Gehäuseöffnung wird bei einer solchen Ausbildung des Funktionsteiles dadurch erreicht, daß den beiden von den Halteelementen untergriffenen Begrenzungskanten jeweils ein Anschlagglied zugeordnet ist und der Abstand zwischen diesen gegenüberliegenden Anschlaggliedern gleich oder geringfügig kleiner als der Abstand zwischen den Außenkanten der beiden Halteelemente in derem entspannten Zustand ist.The functional part is securely seated in the housing opening with such a formation of the functional part achieved that the two gripped by the holding elements Boundary edges each assigned a stop member and the distance between them is opposite Stop members equal or slightly smaller than that Distance between the outer edges of the two holding elements in in a relaxed state.

Anhand eines in der Zeichnung dargestellten Ausführungsbeispieles wird die Erfindung nachfolgend näher beschrieben.

Mit 1 ist ein Teil eines Staubsaugergehäuses bezeichnet, an dessen Oberseite eine Gehäuseöffnung 2 vorgesehen ist, die mittels eines Ausblasgitters 3 abdeckbar ist. Das rechteckig ausgebildete Ausblasgitter 3 weist an seinen beiden Schmalseiten als Halteelemente gegenüber dem eigentlichen Gitterkörper 4 des Ausblasgitters 3 gleich weit vorstehende Ansatzleisten 5a und 5b auf. Im eingesetzten Zustand des Ausblasgitters 3 untergreifen diese Ansatzleisten 5a und 5b die entsprechenden Begrenzungskanten 6 der Gehäuseöffnung 2 und halten somit das Ausblasgitter 3 in der Gehäuseöffnung 2. Damit die Ansatzleisten 5a und 5b die Begrenzungskanten 6 untergreifen können, ist der Abstand 7 zwischen den Außenkanten der Ansatzleisten 5a und 5b größer bemessen als die Öffnungsweite 8 der Gehäuseöffnung 2. Die Länge 9 des Gitterkörpers 4 ist gegenüber der Öffnungsweite 8 mindestens um die Breite 10 einer Ansatzleiste 5a bzw.5b kürzer bemessen. Beim Einsetzen des Ausblasgitters 3 in die Gehäuseöffnung 2 wird die eine Ansatzleiste 5a soweit unter die entsprechende Begrenzungskante 6 der Gehäuseöffnung 2 geschoben, bis der gegenüber den Ansatzleisten 5a und 5b erhabene Gitterkörper 4 gegen die Begrenzungskante 6 der Gehäuseöffnung 2 stößt. In dieser Stellung kann dann beim Hineindrücken des Ausblasgitters 3 in die Gehäuseöffnung 2 die andere Ansatzleiste 5b an der entsprechenden Begrenzungskante 6 der Gehäuseöffnung 2 vorbeigeführt werden. Danach muß das Ausblasgitter 3 seitlich verschoben werden, damit auch die andere Ansatzleiste 5b die entsprechende Begrenzungskante 6 untergreift. Das Verschieben des Ausblasgitters 3 erfolgt selbsttätig durch entsprechende Federkräfte.With 1 a part of a vacuum cleaner housing is referred to the top of which a housing opening 2 is provided, the can be covered by means of a discharge grille 3. The rectangular trained discharge grille 3 points to its two Narrow sides as holding elements compared to the actual one Lattice body 4 of the outlet grille 3 protrudes equally far Neck strips 5a and 5b. When in use Blow out grilles 3 reach under these attachment strips 5a and 5b the corresponding boundary edges 6 of the housing opening 2 and thus hold the outlet grille 3 in the housing opening 2. So that the attachment strips 5a and 5b the boundary edges 6 can reach under, is the distance 7 between the outer edges the extension strips 5a and 5b larger than that Opening width 8 of the housing opening 2. The length 9 of the grid body 4 is at least around the opening width 8 Width 10 of an extension bar 5a or 5b is shorter. At the Inserting the outlet grille 3 in the housing opening 2 the one extension bar 5a so far under the corresponding Boundary edge 6 of the housing opening 2 pushed until the lattice body 4 raised in relation to the attachment strips 5a and 5b abuts the boundary edge 6 of the housing opening 2. In this position can then be when pushing in the outlet grille 3 in the housing opening 2, the other extension bar 5b at the corresponding boundary edge 6 of the housing opening 2 to be led past. Then the outlet grille 3 must be on the side be moved so that the other attachment bar 5b engages under corresponding boundary edge 6. The move the outlet grille 3 is carried out automatically by appropriate Spring forces.

Bei dem in FIG 1 und 2 dargestellten Ausführungsbeispiel ist hierzu an den beiden Längsseiten 11 der Gehäuseöffnung 2 durch Einschnitte 12 ein federnder Bereich 13 ausgebildet. In der Mitte dieses Bereiches 13, der der Mitte der Gehäuseöffnung 2 entspricht, ist eine im Querschnitt dreieckförmige Vertiefung 14 vorgesehen. Desgleichen ist in der Mitte des Gitterkörpers 4 an dessen gegenüber den die Halteelemente 5a und 5b aufweisenden Schmalseiten um 90° oder angenähert 90° abgewinkelten Längsseiten 15 jeweils ein im Querschnitt ebenfalls dreieckförmiger Vorsprung 16 angeformt. Dieser Vorsprung 16 verläuft außerdem von der Innenseite zur Oberseite des Ausblasgitters 3 hin keilförmig ansteigend. Beim Einfügen des Ausblasgitters 3 in die Gehäuseöffnung 2 wird, wie bereits erwähnt, die eine Anschlagleiste 5a unter die entsprechende Begrenzungskante 6 der Gehäuseöffnung 2 geschoben und dann das Ausblasgitter in die Gehäuseöffnung 2 hineingedrückt. In dieser Stellung ist der an der Längsseite 15 des Gitterkörpers 4 vorgesehene Vorsprung 16 gegenüber der mittig zur Gehäuseöffnung 2 liegenden Vertiefung 14 seitlich etwas verschoben. Der Vorsprung 16 trifft somit beim Hineindrücken des Ausblasgitters 3 in die Gehäuseöffnung 2 an einer vom Grund 17 der Vertiefung 14 weiter seitlich liegenden Stelle auf die eine Wand 18 der Vertiefung 14 auf. Durch den beim Einfügen des Ausblasgitters 3 in die Gehäuseöffnung 2 auf dieses ausgeübten Druck wird die Längsseite 11 der Gehäuseöffnung 2 in dem federnden Bereich 13 etwas nach außen gedrückt, so daß der Vorsprung 16 in die Vertiefung 14 gleiten kann. Durch den keilförmigen Verlauf des Vorsprunges 16 wird das Hineindrücken desselben in die Vertiefung erleichtert.In the embodiment shown in Figures 1 and 2 for this purpose on the two long sides 11 of the housing opening 2 a resilient region 13 is formed by incisions 12. In the center of this area 13, that of the center of the housing opening 2 corresponds to a triangular cross section Well 14 provided. Likewise, in the middle of the Lattice body 4 on the opposite of which the holding elements 5a and 5b narrow sides by 90 ° or approximately 90 ° angled long sides 15 each in cross section also formed triangular projection 16. This Projection 16 also runs from the inside to Top of the outlet grille 3 rising wedge-shaped. When inserting the outlet grille 3 into the housing opening 2 is, as already mentioned, the one stop bar 5a under the corresponding boundary edge 6 of the housing opening 2 pushed and then the outlet grille into the housing opening 2 pushed in. In this position it is on the long side 15 of the grid body 4 provided projection 16 with respect to depression 14 lying centrally to the housing opening 2 laterally shifted something. The protrusion 16 thus hits when it is pushed in the outlet grille 3 in the housing opening 2 at one from the bottom 17 of the recess 14 lying laterally Place on one wall 18 of the recess 14. By the when inserting the outlet grille 3 into the housing opening 2 on this pressure, the long side 11 of the Housing opening 2 in the resilient area 13 somewhat outwards pressed so that the projection 16 into the recess 14th can slide. Due to the wedge-shaped course of the projection 16 will push the same into the recess facilitated.

Beim Hineindrücken des Ausblasgitters 3 in die Gehäuseöffnung 2 muß außerdem durch entsprechenden seitlichen Druck auf das Ausblasgitter 3 dessen Gitterkörper 4 in Anlage an der entsprechenden Begrenzungskante 6 der Gehäuseöffnung 2 gehalten werden, damit die andere Ansatzleiste 5b an der betreffenden Begrenzungskante 6 vorbeigeführt werden kann. Ist dies geschehen, dann wird das Ausblasgitter 3 losgelassen und der Vorsprung 16 wird durch das Rückfedern der Längsseiten 11 der Gehäuseöffnung 2 in der jeweiligen Vertiefung 14 zentriert. Dabei wird das Ausblasgitter 3 entsprechend seitlich verschoben, so daß auch die andere Ansatzleiste 5b die entsprechende Begrenzungskante 6 der Gehäuseöffnung 2 untergreift. Danach wird das Ausblasgitter 3 durch die in den Vertiefungen 14 zentrierten Vorsprünge 16 in seiner Einbaulage gesichert.When pushing the outlet grille 3 into the housing opening 2 must also by appropriate lateral pressure on the Blow-out grille 3 whose grille body 4 is in contact with the corresponding boundary edge 6 of the housing opening 2 be held so that the other extension bar 5b on the relevant boundary edge 6 can be passed. If this has happened, then the outlet grille 3 is released and the projection 16 is by the spring back of the Long sides 11 of the housing opening 2 in the respective recess 14 centered. The outlet grille 3 becomes corresponding laterally shifted so that the other attachment bar 5b, the corresponding boundary edge 6 of the housing opening 2 reaches under. Then the outlet grille 3 through the projections 16 centered in the recesses 14 in secured in its installation position.

Das Lösen des Ausblasgitters 3 erfolgt durch einen seitlich auf dieses ausgeübten Druck. Als Angriffsflächen zum Ausüben dieses Druckes sind an der Oberseite des Ausblasgitters 3 Fingermulden 19 ausgeformt. Durch einen solchen seitlichen Druck gleiten die Vorsprünge 16 an den schrägen Flächen der Vertiefungen 14 entlang, so daß es zu einer seitlichen Verschiebung des Ausblasgitters 3 kommt, bis die andere Ansatzleiste 5b die Begrenzungskante 6 nicht mehr untergreift. Beim Entlanggleiten der Vorsprünge 16 an den Vertiefungen 14 werden die Längsseiten 11 in ihrem federnden Bereich 13 entsprechend nach außen geweitet. Durch die Spannung des federnden Bereiches 13 wird das Ausblasgitter 3, wenn es genügend weit seitlich verschoben ist, aus der Gehäuseöffnung 2 herausgedrückt.The discharge grille 3 is released by a side to this pressure. As targets to exercise of this pressure are on the top of the outlet grille 3 Finger depressions 19 formed. By such a side Pressure slide the projections 16 on the inclined surfaces of the Wells 14 along so that it becomes a lateral Displacement of the outlet grille 3 comes up to the other Extension bar 5b no longer engages under the boundary edge 6. When the projections 16 slide along the depressions 14 are the long sides 11 in their resilient Area 13 expanded accordingly outwards. Through the Tension of the resilient area 13, the outlet grille 3, if it is shifted sideways enough out of the Housing opening 2 pushed out.

Bei dem Ausführungsbeispiel nach FIG 3 und 4 ist an der einen Ansatzleiste 5a durch einen bogenförmigen Ausschnitt 20 ein federnder Bügel 21 gebildet. Im Inneren des Staubsaugergehäuses 1 sind den Begrenzungskanten 6 Anschlagglieder 22 und 23 zugeordnet. Der lichte Abstand 24 dieser Anschlagglieder 22 und 23 ist gleich groß bzw. vorteilhafterweise geringfügig kleiner als der Abstand 7 zwischen den Außenkanten der Ansatzleisten 5a und 5b gewählt. Beim Einsetzen des Ausblasgitters 3 in die Gehäuseöffnung 2 wird dieses mit der einen Ansatzleiste 5a unter die entsprechende Begrenzungskante 6 der Gehäuseöffnung 2 eingesteckt. Dabei trifft der federnde Bügel 21 auf das eine Anschlagglied 22. Durch seitlichen Druck auf das Ausblasgitter 3 wird der federnde Bügel 21 verformt und dabei gespannt. Infolge der Verformung des federnden Bügels 21 kann das Ausblasgitter 3 gegenüber der Gehäuseöffnung 2 soweit verschoben werden, daß es mit seiner anderen Ansatzleiste 5b an der entsprechenden Begrenzungskante 6 der Gehäuseöffnung 2 vorbei in diese hineingedrückt werden kann. Danach wird das Ausblasgitter 3 durch die Spannung des federnden Bügels 21 seitlich verschoben, so daß auch die andere Ansatzleiste 5b die Begrenzungskante 6 untergreift und schließlich an dem anderen Anschlagglied 23 zur Anlage kommt. Da der lichte Abstand 24 zwischen den Anschlaggliedern 22 und 23 dem Abstand 7 zwischen den Außenkanten der Ansatzleisten 5a und 5b entspricht, ist das Ausblasgitter 3 in seiner Lage gegen seitliches Verschieben gesichert und wird durch die die Begrenzungskante 6 untergreifenden Ansatzleisten 5a und 5b in der Gehäuseöffnung 2 gehalten. Wird der lichte Abstand 24 zwischen den Anschlaggliedern 22 und 23 etwas kleiner als der Abstand 7 zwischen den Außenkanten der Ansatzleisten 5a und 5b gewählt, dann bleibt der federnde Bügel 21 etwas gespannt und hält das Ausblasgitter 3 mit seinen Ansatzleisten 5a und 5b in Anlage an den Anschlaggliedern 22 und 23. Damit wird ein Klappern des Ausblasgitters 3 verhindert.In the embodiment of Figures 3 and 4 is on one Neck bar 5a through an arcuate cutout 20 resilient bracket 21 formed. Inside the vacuum cleaner housing 1 are the boundary edges 6 stop members 22nd and 23 assigned. The clear distance 24 of these stop members 22 and 23 is the same size or advantageously slightly smaller than the distance 7 between the outer edges the attachment strips 5a and 5b selected. When inserting the outlet grille 3 in the housing opening 2 with this one extension bar 5a under the corresponding boundary edge 6 of the housing opening 2 inserted. It hits the resilient bracket 21 on the one stop member 22. By lateral pressure on the outlet grille 3 is the resilient Bracket 21 deformed and tensioned. As a result of the deformation of the resilient bracket 21, the outlet grille 3 opposite the housing opening 2 are moved so far that it with its other attachment bar 5b at the corresponding boundary edge 6 of the housing opening 2 pressed into it can be. Then the outlet grille 3 through the Tension of the resilient bracket 21 laterally shifted so that the other attachment bar 5b also engages under the boundary edge 6 and finally on the other stop member 23 for Facility is coming. Since the clear distance 24 between the stop members 22 and 23 the distance 7 between the outer edges of the Approach strips 5a and 5b corresponds to the outlet grille 3 secured in its position against lateral displacement and is by the attachment strips below the boundary edge 6 5a and 5b held in the housing opening 2. Will the clear distance 24 between the stop members 22 and 23rd slightly smaller than the distance 7 between the outer edges of the Neck strips 5a and 5b selected, then the resilient remains Bracket 21 a little tense and keeps the outlet grille 3 its shoulder strips 5a and 5b in contact with the stop members 22 and 23. This will make the exhaust grate rattle 3 prevented.

Das Lösen des Ausblasgitters 3 erfolgt wiederum durch entsprechenden seitlichen Druck auf dasselbe, so daß dieses gegen den nachgebenden federnden Bügel 21 soweit seitlich verschoben wird, bis die andere Ansatzleiste 5b die Begrenzungskante 6 nicht mehr untergreift und das Ausblasgitter 3 damit aus der Gehäuseöffnung 2 herausgenommen werden kann.The discharge grille 3 is released again by appropriate lateral pressure on the same so that this against the yielding resilient bracket 21 to the side is moved until the other attachment bar 5b the boundary edge 6 no longer reaches under and the outlet grille 3 so that can be removed from the housing opening 2.

Ein wiederholtes Lösen und Einsetzen des Ausblasgitters 3 kann dann erforderlich sein, wenn dieses eine von der normalen der Gitterfläche abweichende Ausblasrichtung. besitzt. Es kann dann durch Wenden des Ausblasgitters 3 die Ausblasrichtung geändert werden.Repeated loosening and insertion of the outlet grille 3 may be required if this is one of the Normal discharge direction deviating from the grille area. owns. It can then by turning the outlet grille 3 Blow direction can be changed.
