Description
STAUBSAUGER MIT BEWEGBARER STOSSLEISTE VACUUM CLEANER WITH MOVABLE BUMPER
Die Erfindung betrifft einen Staubsauger mit einem Gehäuse, in das ein Saugstutzen einmündet zum Anschließen eines Saugschlauches und an dem Laufrollen zum Verfahren des Staubsaugers entlang einer zu reinigenden Bodenfläche drehbar gelagert sind, und mit einer das Gehäuse in Umfangsrichtung zumindest teilweise umgebenden Stoßleiste, die außenseitig über das Gehäuse hervorsteht.The invention relates to a vacuum cleaner with a housing into which a suction nozzle opens for connecting a suction hose and are rotatably mounted on the rollers for moving the vacuum cleaner along a floor surface to be cleaned, and with a housing circumferentially at least partially surrounding bumper, the outside over the housing protrudes.
Ein derartiger Staubsauger ist aus der Patentschrift DE 196 16 156 Cl bekannt. Mit seiner Hilfe kann eine Bodenfläche gereinigt werden. Hierbei wird der Staubsauger vom Benutzer üblicherweise am Saugschlauch hinter sich her gezogen. Trifft der Staubsauger auf ein Hindernis, beispielsweise ein Möbelstück, so wird der Stoß gegen das Hindernis von der Stoßleiste abgeschwächt. Wird allerdings beim Auftreffen auf das Hindernis vom Benutzer eine Zugbelastung auf den Staubsauger ausgeübt, so kann dies zur Folge haben, daß die Stoßleiste am Hindernis entlang gleitet und sich dabei der Staubsauger verdreht. Dadurch wird die Verfahrbarkeit des Staubsaugers beeinträchtigt und die Gefahr einer Beschädigung des Hindernisses ist nicht auszuschließen.Such a vacuum cleaner is known from the patent DE 196 16 156 Cl. With its help, a floor surface can be cleaned. In this case, the user usually pulls the vacuum cleaner on the suction hose behind him. If the vacuum cleaner hits an obstacle, for example a piece of furniture, the impact against the obstacle is attenuated by the protective strip. However, if the user exerts a tensile load on the vacuum cleaner when hitting the obstacle, this may result in the impact strip sliding along the obstacle while the vacuum cleaner is twisting. As a result, the mobility of the vacuum cleaner is impaired and the risk of damaging the obstacle can not be ruled out.
Aufgabe der vorliegenden Erfindung ist es, einen Staubsauger der gattungsgemäßen Art derart weiterzubilden, daß er auch beim Auftreffen auf ein Hindernis auf einfache Weise verfahrbar ist, ohne daß die Gefahr einer Beschädigung des Hindernisses besteht. Diese Aufgabe wird bei einem Staubsauger der eingangs genannten Art erfin- dungsgemäß dadurch gelöst, daß die Stoßleiste in Umfangsrichtung des Gehäuses bewegbar am Gehäuse gelagert ist.Object of the present invention is to develop a vacuum cleaner of the generic type such that it can be moved easily when hitting an obstacle without the risk of damaging the obstacle exists. This object is achieved according to the invention in a vacuum cleaner of the type mentioned, that the bumper is movably mounted on the housing in the circumferential direction of the housing.
Die bewegliche Lagerung der Stoßleiste am Gehäuse ermöglicht es, diese bei einem Auftreffen auf ein Hindernis am Hindernis abzurollen, so daß keine Gefahr besteht, daß das Hindernis beschädigt wird. Hierbei wird lediglich von der Stoßleiste eine Abrollbewegung durchgeführt, nicht aber vom Gehäuse. Ein Verdrehen des Staubsaugers beim Auftreffen auf das Hindernis wird dadurch verhindert. Der vom Benutzer hinter sich hergezogene Staubsauger fährt somit am Hindernis entlang und ist deshalb auf einfache Weise verfahrbar.The movable mounting of the bumper strip on the housing makes it possible to roll them when hitting an obstacle on the obstacle, so that there is no risk that the obstacle is damaged. Here, a rolling movement is performed only by the bumper, but not by the housing. A rotation of the vacuum cleaner when hitting the obstacle is prevented. The vacuum cleaner pulled behind by the user thus travels along the obstacle and can therefore be moved in a simple manner.
Günstig ist es, wenn die Stoßleiste das Gehäuse in Umfangsrichtung vollständig umgibt. Es kann allerdings auch vorgesehen sein, daß die Stoßleiste lediglich in einem bezogen auf die vom Benutzer über den Saugschlauch auf den Staubsauger einwirkenden Zugbelastung vorderen Bereich des Gehäuses angeordnet ist.It is advantageous if the bumper completely surrounds the housing in the circumferential direction. However, it can also be provided that the bumper is arranged only in a front of the housing relative to the tensile load acting on the vacuum cleaner by the user via the suction hose.
Bei einer besonders bevorzugten Ausführungsform bildet die Stoßleiste einen um eine senkrecht zur Bodenfläche ausgerichtete Drehachse frei drehbaren Stoßring aus. Durch die freie Drehbarkeit des Stoßrings wird die Verfahrbarkeit des Staubsaugers zusätzlich verbessert. Der Stoßring ist bevorzugt kreisringförmig ausgestaltet.In a particularly preferred embodiment, the protective strip forms a shock ring that is freely rotatable about a rotation axis oriented perpendicular to the bottom surface. Due to the free rotation of the shock ring, the movability of the vacuum cleaner is further improved. The shock ring is preferably designed annular.
Es kann beispielsweise vorgesehen sein, daß der Stoßring ein ringförmiges Tragteil umfaßt, an dem außenseitig ein Stoßband aus einem gummielastischen Material gehalten ist. Das Tragteil kann aus einem starren Material, ins- besondere aus einem starren Kunststoffmaterial gefertigt sein und kann dem Stoßring die erforderliche mechanische Belastbarkeit verleihen. Durch den Einsatz des gummielastischen Stoßbands wird beim Auftreffen des Staubsaugers auf ein Hindernis eine Beschädigung desselben verhindert.It can be provided, for example, that the impact ring comprises an annular support member on the outside of a bumper made of a rubber-elastic material is held. The supporting part can be made of a rigid material, in particular be made of a rigid plastic material and can give the bumper the required mechanical strength. The use of the rubber-elastic shock strip prevents the same when hitting the vacuum cleaner on an obstacle damage.
Als günstig hat es sich erwiesen, wenn der Stoßring zwischen einem Gehäuseunterteil und einem Gehäuseoberteil des Staubsaugers angeordnet ist. Das Gehäuseunterteil weist bevorzugt eine wannenförmige Außenkontur auf und umfaßt eine parallel zur Bodenfläche ausgerichtete Bodenwand, an der die Laufrollen drehbar gelagert sind. Hierbei ist es von Vorteil, wenn die Laufrollen jeweils an einem Schwenkteil drehbar gelagert sind, das um eine senkrecht zur Bodenfläche ausgerichtete Schwenkachse verschwenkbar am Gehäuseunterteil gehalten ist.As low it has been found when the shock ring is arranged between a lower housing part and a housing upper part of the vacuum cleaner. The lower housing part preferably has a trough-shaped outer contour and comprises a parallel to the bottom surface aligned bottom wall on which the rollers are rotatably mounted. It is advantageous if the rollers are each rotatably mounted on a pivot member which is held about a pivot axis aligned perpendicular to the bottom surface pivotally mounted on the housing base.
Die Lagerung des Stoßrings erfolgt vorteilhafterweise mit Hilfe von Tragrollen, auf denen der Stoßring aufsitzt. Die Drehachsen der Tragrollen sind bevorzugt radial zur Drehachse des Stoßrings ausgerichtet. Es können beispielsweise vier in Umfangsrichtung in gleichmäßigem Abstand zueinander angeordnete Tragrollen zum Einsatz kommen, auf denen der Stoßring mit einer parallel zur Bodenfläche ausgerichteten Stützfläche aufsitzt.The bearing of the shock ring is advantageously carried out with the help of support rollers on which the shock ring is seated. The axes of rotation of the support rollers are preferably aligned radially to the axis of rotation of the shock ring. For example, four support rollers arranged in the circumferential direction at a uniform distance from one another may be used, on which the impact ring is seated with a support surface aligned parallel to the bottom surface.
Die Tragrollen sind vorzugsweise jeweils an einem Lagerstift gelagert, der am Gehäuseunterteil gehalten ist. Hierbei ist es günstig, wenn die Lagerstifte mit dem Gehäuseunterteil verrastbar sind, denn dadurch wird die Montage des Staubsaugers vereinfacht. Um den Stoßring in radialer Richtung abzustützen, ist bei einer vorteilhaften Ausführungsform vorgesehen, daß der Stoßring an mehreren in Umfangsrich- tung des Gehäuses verteilt angeordneten Stützrollen anliegt. Die Drehachsen der Stützrollen sind bevorzugt parallel zur Drehachse des Stoßrings ausgerichtet. Vorzugsweise kommen vier in Umfangsrichtung des Gehäuses gleichmäßig verteilt angeordnete Stützrollen zum Einsatz. Zur Anlage an die Stützrollen kann der Stoßring beispielsweise eine zylinderförmige, koaxial zur Drehachse des Stoßrings ausgerichtete Stützfläche aufweisen.The support rollers are preferably each mounted on a bearing pin which is held on the housing base. It is advantageous if the bearing pins can be latched to the lower housing part, because the assembly of the vacuum cleaner is simplified. In order to support the thrust ring in the radial direction, it is provided in an advantageous embodiment that the thrust ring rests against a plurality of support rollers distributed in the circumferential direction of the housing. The axes of rotation of the support rollers are preferably aligned parallel to the axis of rotation of the shock ring. Preferably, four in the circumferential direction of the housing evenly distributed support rollers are used. For abutment with the support rollers, the impact ring can have, for example, a cylindrical support surface aligned coaxially to the axis of rotation of the impact ring.
Die Stützrollen sind bei einer vorteilhaften Ausführungsform jeweils an einem Lagerstift gelagert, der mit einem unteren Ende am Gehäuseunterteil und mit einem oberen Ende am Gehäuseoberteil gehalten ist.The support rollers are mounted in an advantageous embodiment in each case on a bearing pin, which is held with a lower end on the lower housing part and with an upper end on the upper housing part.
Bevorzugt ist zwischen zwei benachbarten Stützrollen jeweils eine Tragrolle angeordnet. Dies verleiht dem Stoßring eine hohe mechanische Belastbarkeit.Preferably, a support roller is arranged between each two adjacent support rollers. This gives the bumper a high mechanical strength.
Günstig ist es, wenn das Gehäuseoberteil ein an den Stoßring angrenzendes Basisteil aufweist, an das sich dem Stoßring abgewandt ein Hauptteil anschließt, wobei das Basisteil außenseitig über das Hauptteil hervorsteht. Das Hauptteil ist somit gegenüber dem Basisteil und dem Stoßring zurückgesetzt. Eine Beschädigung des Hauptteils beim Auftreffen des Staubsaugers auf ein Hindernis wird dadurch verhindert. Außerdem erhält der Staubsauger durch das außenseitig über das Hauptteil hervorstehende Basisteil eine hohe Standfestigkeit. Zieht der Benutzer den Staubsauger am Saugschlauch hinter sich her, so besteht keine Gefahr, daß der Staubsauger verkippt. Die Verfahrbar- keit des Staubsaugers wird folglich verbessert. Von Vorteil ist es, wenn das Gehäuseunterteil und/oder das Basisteil im Übergangsbereich zum Stoßring bogenförmig gekrümmt sind. Beispielsweise kann vorgesehen sein, daß das Basisteil und das Gehäuseunterteil in ihrem dem Stoßring benachbarten Bereich konvex gekrümmt sind.It is advantageous if the housing upper part has a base part adjoining the impact ring, to which a main part adjoins the impact ring, wherein the base part protrudes on the outside over the main part. The main part is thus reset relative to the base part and the impact ring. Damage to the main part when hitting the vacuum cleaner on an obstacle is prevented. In addition, the vacuum cleaner receives by the outside over the main part protruding base part high stability. If the user pulls the vacuum cleaner on the suction hose behind him, there is no danger that the vacuum cleaner tips. The mobility of the vacuum cleaner is thus improved. It is advantageous if the lower housing part and / or the base part are arcuately curved in the transition region to the thrust ring. For example, it can be provided that the base part and the lower housing part are convexly curved in their region adjacent to the impact ring.
Bei einer besonders bevorzugten Ausführungsform des erfindungsgemäßen Staubsaugers ist das Basisteil zylindersymmetrisch ausgestaltet und das Hauptteil weist einen kreisbogenförmig gekrümmten Mittelabschnitt auf, der das Basisteil überspannt. Es hat sich gezeigt, daß dadurch die Verfahrbarkeit des Staubsaugers unter Gewährleistung einer hohen Kippsicherheit weiter verbessert werden kann. Das zylindersymmetrische Basisteil weist eine Symmetrieachse auf, die in der Ebene verläuft, die durch den kreisbogenförmig gekrümmten Mitte I abschnitt definiert wird. An den Mittelabschnitt schließt sich seitlich jeweils ein Seitenabschnitt des Gehäuseoberteils an. Einer der Seitenabschnitte kann einen Staubraumdeckel aufweisen, der vom Benutzer zum Einsetzen eines Staubbehälters in das Gehäuse ausgeschwenkt oder abgehoben werden kann. Der andere Seitenabschnitt des Gehäuseoberteils weist bei einer vorteilhaften Ausführungsform ein Zubehörfach auf, das von einem Zubehörfachdeckel abgedeckt ist. Im Zubehörfach können verschiedene Saugdüsen deponiert werden, die wahlweise mit dem freien Ende des Saugschlauches verbindbar sind. Es kann auch vorgesehen sein, daß an einem Seitenabschnitt ein Filterfachdeckel angeordnet ist, der ein Filteraufnahmefach überdeckt und Auslaßöffnungen aufweist, über die die Abluft des Staubsaugers abgegeben werden kann. Die Abluft durchströmt hierbei im Filteraufnahmefach ein Luftfilter, vorzugsweise ein HEPA-Filter. Durch Abnehmen oder Verschwen- ken des Filterfachdeckels ist dem Benutzer das Filteraufnahmefach zugänglich, so daß er das Abluftfilter auf einfache Weise entnehmen kann.In a particularly preferred embodiment of the vacuum cleaner according to the invention, the base part is designed cylindrically symmetrical and the main part has a circular arc-shaped curved central portion which spans the base part. It has been shown that thereby the mobility of the vacuum cleaner can be further improved while ensuring a high tilting safety. The cylindrically symmetrical base part has an axis of symmetry which extends in the plane which is defined by the arcuate curved center I section. At the middle section, a side section of the housing upper part adjoins laterally. One of the side sections may have a dust compartment lid which can be swung or lifted by the user to insert a dust container into the housing. The other side portion of the upper housing part, in an advantageous embodiment, an accessory compartment, which is covered by an accessory compartment cover. In the accessory compartment various suction nozzles can be deposited, which can be connected to the free end of the suction hose. It can also be provided that on a side portion a filter compartment cover is arranged, which covers a filter receiving compartment and having outlet openings through which the exhaust air of the vacuum cleaner can be discharged. The exhaust air flows through this in the filter receiving compartment an air filter, preferably a HEPA filter. By removing or blurring ken the filter compartment cover the user is the filter receptacle accessible so that he can remove the exhaust filter in a simple manner.
Oberseitig ist am Mitte I abschnitt des Staubsaugers bei einer bevorzugten Ausführungsform ein kreisbogenförmig gekrümmter Handgriff gehalten, an dem der Staubsauger angehoben werden kann. Der Handgriff ist für den Benutzer auf einfache Weise zugänglich.On the upper side portion of the vacuum cleaner is held in a preferred embodiment, a circular arc-shaped curved handle on which the vacuum cleaner can be raised. The handle is easily accessible to the user.
Von Vorteil ist es, wenn der Saugstutzen am Mittelabschnitt gehalten ist. Der Mittelabschnitt kann eine hohe mechanische Stabilität aufweisen, und eine Zugbelastung, die vom Benutzer über den Saugschlauch auf den Staubsauger ausgeübt wird, wird bei Anordnung des Saugstutzens am Mittelabschnitt von diesem aufgenommen.It is advantageous if the suction nozzle is held at the central portion. The central portion may have a high mechanical stability, and a tensile load exerted by the user on the vacuum hose on the vacuum cleaner, is taken with the arrangement of the suction nozzle at the central portion thereof.

The upper housing part 16 is seated on supports 53 of the lower housing part 14 and is bolted to the lower housing part 14 via connecting screws, not shown in the drawing.
Das Gehäuseunterteil 14 und das Gehäuseoberteil 16 definieren zwischen sich einen umlaufenden Ringraum 55, der zwischen der Seitenwand 28 des Gehäuseunterteils 14 und der Seitenwand 31 des Basisteils 30 angeordnet ist und den Stoßring 18 aufnimmt. Letzterer weist ein starres, in der Draufsicht kreisringförmiges Tragteil 57 auf, das auf seiner Außenseite ein aus einem gummielastischen Material gefertigtes Stoßband 59 trägt. Das Stoßband 59 ragt außenseitig über den Ringraum 55 und folglich auch über das Gehäuse 12 hervor.The lower housing part 14 and the upper housing part 16 define therebetween a circumferential annular space 55 which is arranged between the side wall 28 of the housing lower part 14 and the side wall 31 of the base part 30 and receives the thrust ring 18. The latter has a rigid, in plan view annular support member 57 which carries on its outside a made of a rubber-elastic material bumper 59. The bumper 59 protrudes on the outside via the annular space 55 and consequently also on the housing 12.
Innenseitig ist an das Tragteil 57 ein im Querschnitt im wesentlichen Z-förmi- ges Halteteil 61 angeformt, das eine zylindermantelförmige Stützwand 34 ausbildet, an die sich ein radial nach innen gerichteter Stützrand 66 anschließt.On the inside, a holding part 61 which is substantially Z-shaped in cross section is formed on the carrying part 57 and forms a cylindrical jacket-shaped supporting wall 34, to which a radially inwardly directed supporting edge 66 adjoins.
Der Stoßring 18 ist um eine senkrecht zur Bodenwand 20 ausgerichtete Drehachse 68 frei drehbar. Die Drehachse 68 verläuft in der Mittelebene 35 des Gehäuses 12 und ist kolinear ausgerichtet zur Symmetrieachse des zylindersymmetrischen Basisteils 30. Radial zur Drehachse 68 ausgerichtet sind am Gehäuseunterteil 14 in Umfangsrichtung des Gehäuses 12 in gleichmäßigem Abstand zueinander angeordnete erste Lagerstifte 70 gehalten, die mit dem Gehäuseunterteil 14 verrastet sind und an denen jeweils eine Tragrolle 72 frei drehbar gelagert ist. Der Stoßring 18 stützt sich mit dem Stützrand 66 auf den Tragrollen 72 ab.The thrust ring 18 is freely rotatable about an axis of rotation 68 aligned perpendicular to the bottom wall 20. The axis of rotation 68 extends in the median plane 35 of the housing 12 and is aligned colinearly to the axis of symmetry of the cylindrically symmetrical base portion 30. Radially aligned with the axis of rotation 68 are held on the housing base 14 in the circumferential direction of the housing 12 at a uniform distance from one another arranged first bearing pins 70 which are connected to the housing lower part 14 are latched and on each of which a support roller 72 is freely rotatably mounted. The thrust ring 18 is supported by the support edge 66 on the support rollers 72.
Parallel zur Drehachse 68 sind in Umfangsrichtung des Gehäuses 12 in gleichmäßigem Abstand zueinander vier zweite Lagerstifte 74 dem Ringraum 55 benachbart angeordnet, an denen jeweils eine Stützrolle 76 frei drehbar gelagert ist. Der Stoßring 18 stützt sich mit der Stützwand 64 in radialer Richtung an den Stützrollen 76 ab. Die zweiten Lagerstifte 74 sind mit einem unteren Ende 78 am Gehäuseunterteil 14 und mit einem oberen Ende 79 am Basisteil 30 gehalten. Das Gehäuseunterteil 14 und das Basisteil 30 weisen hierzu entsprechende Ausnehmungen auf, in die die zweiten Lagerstifte 74 mit ihrem jeweiligen Ende 78 bzw. 79 eintauchen.Parallel to the axis of rotation 68 four second bearing pins 74 are arranged adjacent to the annular space 55 in the circumferential direction of the housing 12 at a uniform distance from each other, on each of which a support roller 76 freely rotatably mounted is. The thrust ring 18 is supported by the support wall 64 in the radial direction on the support rollers 76. The second bearing pins 74 are held with a lower end 78 on the lower housing part 14 and an upper end 79 on the base part 30. For this purpose, the lower housing part 14 and the base part 30 have corresponding recesses into which the second bearing pins 74 with their respective ends 78 and 79 dive.
Zum Reinigen der Bodenfläche 26 wird an den Saugstutzen 41 ein Saugschlauch angeschlossen. Der Benutzer zieht hierbei üblicherweise den Staubsauger 10 mittels des Saugschlauches hinter sich her. Trifft der Staubsauger 10 auf ein Hindernis, beispielsweise auf ein Möbelstück, so stößt er mit dem weichen Stützband 59 gegen das Hindernis und kann sich anschließend aufgrund der drehbaren Lagerung des Stoßrings 18 am Hindernis entlang abrollen, wobei das Gehäuse 12 seine Ausrichtung relativ zum Benutzer beibehält. Der Staubsauger 10 zeichnet sich somit durch eine einfache Verfahrbarkeit aus. Außerdem weist er eine sehr kompakte Bauform und eine hohe Standfestigkeit auf. To clean the bottom surface 26, a suction hose is connected to the suction 41. The user usually pulls the vacuum cleaner 10 here by means of the suction hose behind him. Hits the vacuum cleaner 10 to an obstacle, for example, a piece of furniture, so he pushes with the soft support belt 59 against the obstacle and can then roll due to the rotatable mounting of the thrust ring 18 along the obstacle, the housing 12 maintains its orientation relative to the user , The vacuum cleaner 10 is thus characterized by a simple mobility. In addition, it has a very compact design and high stability.
