Aufgabe der Erfindung ist es, einen Staubsauger mit einer verbesserten Art der Aufbewahrung einer Saugdüseneinheit am Staubsauger zu schaffen.The object of the invention is to provide a vacuum cleaner with an improved way of storing a suction nozzle unit on the vacuum cleaner.

Diese Aufgabe wird bei einem gattungsgemäßen Staubsauger dadurch gelöst, dass die Saugdüseneinheit zur Befestigung am Gehäuse des Staubsaugers ein Rastmittel aufweist, welches in ein Gegenrastmittel am Gehäuse eingreift.This object is achieved in a generic vacuum cleaner characterized in that the suction nozzle unit for attachment to the housing of the vacuum cleaner has a locking means which engages in a counter-locking means on the housing.

Durch die erfindungsgemäße Ausbildung von Staubsauger und Saugdüseneinheit wird eine verbesserte Aufbewahrung für die Saugdüseneinheit erzielt. Insbesondere besteht der Vorteil darin, dass sich die Saugdüseneinheit besser in die Form des Staubsaugers integriert. Da sich die Saugdüseneinheit in den Staubsauger im Wesentlichen vollständig integriert, wird die Gefahr verringert, dass der Staubsauger während des Betriebes aufgrund von deutlich vorspringenden Teilen der Saugdüseneinheit bspw. an Möbelstücken hängen bleibt. Damit ist auch die Gefahr wesentlich reduziert, dass die Saugdüseneinheit während des Betriebes des Staubsaugers beschädigt wird. Für den Benutzer erscheint der erfindungsgemäße Staubsauger auch optisch ansprechender, da keine wesentlich vorstehenden Teile mehr vorhanden sind, welche die den Staubsauger prägende Form optisch stören würden.The inventive design of the vacuum cleaner and suction nozzle unit an improved storage for the suction nozzle unit is achieved. In particular, the advantage is that the suction nozzle unit is better integrated into the shape of the vacuum cleaner. Since the suction nozzle unit in the vacuum cleaner substantially completely integrated, the risk is reduced that the vacuum cleaner during operation due to significantly projecting parts of the suction nozzle unit, for example. Hanging on pieces of furniture. This also significantly reduces the risk that the suction nozzle unit is damaged during operation of the vacuum cleaner. For the user, the vacuum cleaner according to the invention also appears visually appealing, since no substantially protruding parts are present, which would disturb the shape of the vacuum cleaner form visually.

In einer bevorzugten Ausgestaltung der Erfindung schließt der Wandabschnitt der Saugdüseneinheit eine am Gehäuseunterteil vorgesehene Aufnahme ab. Dabei kann die am Gehäuseunterteil vorgesehene Aufnahme nischenartig hinter die äußere Oberfläche des Gehäuseunterteils zurückspringen. Insbesondere kann die rückspringende Aufnahme direkt am Gehäuseunterteil angeformt sein. Aufgrund der gehäuseunterteilseitigen Anordnung der Aufnahme bleibt die Saugdüseneinheit in der eingesetzten Position für den Benutzer des Staubsaugers weitgehend optisch verborgen, ohne dass die Saugdüseneinheit von einer gesonderten Abdeckung überdeckt werden muss. Aufgrund des flächig abschließenden Wandabschnitts der Saugdüseneinheit kann diese aber auch in einer am Gehäuseoberteil vorgesehenen Aufnahme einsetzbar sein. Wesentlich für die Erfindung ist ein Wandabschnitt der Saugdüseneinheit, der in seiner Gestalt der Form des Staubsaugergehäuses angepasst ist. Die Anpassung wird dabei im Wesentlichen durch Weiterführung der Oberflächenkontur des Staubsaugers über den Wandabschnitt der Saugdüseneinheit hinweg erreicht. Für den erfindungswesentlichen Kern ist es dabei unschädlich, wenn zum Zwecke weiterer Funktionen Teile der Saugdüseneinheit geringfügig über den angepassten Wandabschnitt nach außen vorstehen.In a preferred embodiment of the invention, the wall section of the suction nozzle unit includes a receptacle provided on the lower housing part. In this case, the receptacle provided on the lower housing part can spring back niche-like behind the outer surface of the housing lower part. In particular, the recessed receptacle can be formed directly on the housing base. Due to the lower housing-side arrangement of the intake, the suction nozzle unit remains largely optically hidden in the inserted position for the user of the vacuum cleaner, without the suction nozzle unit having to be covered by a separate cover. Due to the flat final wall portion of the suction nozzle unit but this can also be used in a provided on the housing top recording. Essential to the invention is a wall portion of the suction nozzle unit, which is adapted in shape to the shape of the vacuum cleaner housing. The adaptation is achieved essentially by continuing the surface contour of the vacuum cleaner over the wall section of the suction nozzle unit. For the core essential to the invention, it is harmless if, for the purpose of further functions, parts of the suction nozzle unit protrude slightly beyond the adapted wall section to the outside.

Der Wandabschnitt kann von einer Seitenwand des Saugdüsengehäuses gebildet werden. Durch diese Ausgestaltung der Erfindung erübrigt es sich, einen gesonderten Wandabschnitt an der Saugdüseneinheit vorzusehen, der die rückspringende Aufnahme im Wesentlichen flächig abschließt. Statt einem gesonderten Wandabschnitt wird dabei vorzugsweise eine Seitenwand des Saugdüsengehäuses in seiner Gestalt der Form des Gehäuses angepasst. Vorzugsweise ist die Saugdüseneinheit als einstückiges Kunststoffspritzgussteil ausgebildet, d. h. der Wandabschnitt bzw. die Seitenwand ist direkt an die Saugdüseneinheit angeformt.The wall portion may be formed by a side wall of the suction nozzle housing. By this embodiment of the invention, it is unnecessary to provide a separate wall section on the suction nozzle unit, which terminates the recessed receptacle substantially flat. Instead of a separate wall section, a side wall of the suction nozzle housing is preferably adapted in its shape to the shape of the housing. Preferably, the suction nozzle unit is formed as a one-piece plastic injection molded part, d. H. the wall section or the side wall is formed directly on the suction nozzle unit.

Vorzugsweise ist der Wandabschnitt Teil einer Polsterdüse, d. h. die Saugdüseneinheit ist als Polsterdüse ausgebildet. Die Polsterdüse weist ein haubenartiges Gehäuseoberteil auf, dessen Deckfläche den Wandabschnitt bildet.The wall section is preferably part of a upholstery nozzle, that is to say the suction nozzle unit is designed as a upholstery nozzle. The upholstery nozzle has a hood-like housing upper part, whose top surface forms the wall section.

In einer bevorzugten Ausgestaltung der Erfindung weist die Saugdüseneinheit einen rohrförmigen, den Wandabschnitt durchdringenden Anschlussstutzen für ein Saugrohr oder einen Saugschlauch des Staubsaugers auf. Über den rohrförmigen Anschlussstutzen wird die vorzugsweise als Polsterdüse ausgebildete Saugdüseneinheit an das Saugrohr bzw. an den Saugschlauch des Staubsaugers angeschlossen. Der rohrförmige Anschlussstutzen kann nach außen bündig mit dem Wandabschnitt der Saugdüseneinheit abschließen. Der rohrförmige Anschlussstutzen kann jedoch geringfügig über die Oberfläche des Wandabschnitts hervorstehen und einen Halteabschnitt bilden, durch den die Saugdüseneinheit von einem Benutzer von Hand gegriffen und aus der Aufnahme des Staubsaugers herausgenommen werden kann. Damit wird die Entnahme der Saugdüseneinheit aus der Aufnahme am Staubsauger erleichtert.In a preferred embodiment of the invention, the suction nozzle unit has a tubular, the wall section penetrating connection piece for a suction pipe or a suction hose of the vacuum cleaner. About the tubular connection piece, preferably designed as a cushion nozzle suction nozzle unit is connected to the suction pipe or to the suction hose of the vacuum cleaner. The tubular connection piece can terminate flush with the wall section of the suction nozzle unit. However, the tubular spigot may project slightly beyond the surface of the wall portion and form a holding portion through which the suction nozzle unit can be gripped by a user by hand and taken out of the receptacle of the vacuum cleaner. This facilitates the removal of the suction nozzle unit from the receptacle on the vacuum cleaner.

Um beim Greifen von Hand ein Abrutschen von dem geringfügig vorstehenden, rohrförmigen Anschlussstutzen zu verhindern, kann der rohrförmige Anschlussstutzen mindestens einen Halteabschnitt aufweisen, durch den die Saugdüseneinheit aus der rückspringenden Aufnahme entnehmbar ist. Durch den mindestens einen Halteabschnitt wird ein Hinterschnitt gebildet, der von einer Hand des Benutzers hintergriffen werden kann, wodurch ein Abrutschen der Hand von der Saugdüseneinheit verhindert ist.In order to prevent hand slipping from the slightly projecting, tubular connecting piece when gripping by hand, the tubular connecting piece can have at least one holding portion, through which the suction nozzle unit can be removed from the recessed receptacle. By the at least one holding portion an undercut is formed, which can be engaged behind by a hand of the user, whereby a slipping of the hand is prevented by the suction nozzle unit.

Vorzugsweise sind zwei kreisabschnittsförmige Halteabschnitte gegenüberliegend an einer Außenwand des rohrförmigen Anschlussstutzens vorgesehen. Vorzugsweise wird die Saugdüseneinheit am rohrförmig vorstehenden Anschlussstutzen mittels Daumen und Zeigefinger an gegenüberliegenden Seiten hinter den kreisabschnittsförmigen Halteabschnitten gegriffen. Während des Herausziehens der Saugdüseneinheit aus der Aufnahme kommen Daumen und Zeigefinger an den Rückseiten der kreisabschnittsförmigen Halteabschnitte zu liegen, wodurch ein Abrutschen der Finger von dem rohrförmigen Anschlussstutzen zuverlässig verhindert ist.Preferably, two circular portion-shaped holding portions are provided opposite to an outer wall of the tubular connecting piece. Preferably, the suction nozzle unit is gripped on the tubular projecting connecting piece by means of thumb and forefinger on opposite sides behind the circular segment-shaped holding sections. During the extraction of the suction nozzle unit from the recording thumb and forefinger come to rest on the backs of the circular portion-shaped holding portions, whereby a slipping of the fingers of the tubular connection piece is reliably prevented.

Zur Befestigung der Saugdüseneinheit am Gehäuse des Staubsaugers kann die Saugdüseneinheit das erfindungsgemäße Rastmittel aufweisen, welches in ein Gegenrastelement am Gehäuse eingreift. Durch das Rastmittel wird die Saugdüseneinheit zuverlässig in der Aufnahme des Staubsaugers gehalten. Dabei kann die Aufnahme auf in andere Richtungen als ausschließlich nach oben hin offen ausgebildet werden. Die Saugdüseneinheit wird mit der erfindungsgemäßen Ausbildung auch ohne Schwerkraftunterstützung in der Aufnahme gehalten. Durch das Rastmittel wird es möglich, dass die Öffnung der Aufnahme bspw. an einer Seitenwand des Staubsaugers oder sogar an der Unterseite des Staubsaugers vorgesehen sein kann. Ein Herausrutschen der Saugdüseneinheit aus der Aufnahme aufgrund der Schwerkraft ist damit zuverlässig verhindert. Durch das erfindungsgemäße Rastmittel kann die Lage der Öffnung der Aufnahme weitgehend frei gewählt werden.For attachment of the suction nozzle unit on the housing of the vacuum cleaner, the suction nozzle unit may comprise the latching means according to the invention, which engages in a counter-latching element on the housing. By the locking means, the suction nozzle unit is reliably held in the receptacle of the vacuum cleaner. The recording can be formed open in directions other than exclusively upwards. The suction nozzle unit is held with the inventive design without gravity support in the recording. By the latching means, it is possible that the opening of the receptacle, for example, may be provided on a side wall of the vacuum cleaner or even on the underside of the vacuum cleaner. Slipping out of the suction nozzle unit from the recording due to gravity is thus reliably prevented. By the locking means according to the invention, the position of the opening of the recording can be chosen largely freely.

Das Rastmittel wird vorzugsweise von mindestens zwei U-förmigen Laschen an der Saugdüseneinheit gebildet, die in der verrasteten Position mindestens eine am Gehäuse des Staubsaugers vorgesehene Rippe umgreifen. Die U-förmige Lasche bzw. die Laschen können in ihrem entspannten Zustand vorzugsweise eine geringere Spaltweite als die Dicke der Rippe aufweisen. Beim Aufsetzen der U-förmigen Laschen auf die am Staubsauger vorgesehene Rippe werden die U-förmigen Laschen elastisch aufgeweitet und klemmen sich aufgrund der elastischen Vorspannkräfte an die am Staubsauger vorgesehene Rippe. Durch diese Ausbildung wird eine zuverlässige Verrastung der Saugdüseneinheit am Staubsauger geschaffen, die von einem Benutzer bei Bedarf wieder leicht lösbar ist.The latching means is preferably formed by at least two U-shaped tabs on the suction nozzle unit, which engage in the latched position at least one provided on the housing of the vacuum cleaner rib. The U-shaped tab or the tabs may preferably have a smaller gap width than the thickness of the rib in their relaxed state. When placing the U-shaped tabs on the provided on the vacuum cleaner rib, the U-shaped tabs are elastically expanded and clamp due to the elastic biasing forces on the provided on the vacuum cleaner rib. By this design, a reliable locking of the suction nozzle unit is created on the vacuum cleaner, which is easily solved by a user when needed again.

Zweckmäßigerweise sind an einer den U-förmigen Laschen zugewandten Seitenwand der Polsterdüse Abstandshalter vorgesehen.Expediently, spacers are provided on a side wall of the upholstery nozzle facing the U-shaped tabs.

Besagte Abstandshalter können als linsenförmig vorstehende Noppen ausgebildet und vorzugsweise an die Seitenwand angeformt sein.Said spacers may be formed as lumps projecting lugs and preferably formed on the side wall.

Wenn die Saugdüseneinheit bspw. zweiteilig ausgebildet wird, so kann an einer Innenwand des rohrförmigen Anschlussstutzens ein zusätzliches Rastmittel vorgesehen sein, durch das bspw. eine Fugendüse mit der vorzugsweise als Polsterdüse ausgebildeten Saugdüseneinheit verrastbar ist. Dies hat den Vorteil, dass der Benutzer in der Aufnahme des Staubsaugers zwei Arten von Düsen zur Verfügung hat. Je nach Wunsch kann der Benutzer entweder die Fugendüse oder die Polsterdüse auf das Saugrohr bzw. den Saugschlauch des Staubsaugers aufsetzen.If, for example, the suction nozzle unit is formed in two parts, then an additional latching means can be provided on an inner wall of the tubular connection piece, by means of which, for example, a crevice nozzle can be latched with the suction nozzle unit, which is preferably designed as a cushioning nozzle. This has the advantage that the user has two types of nozzles available in the receptacle of the vacuum cleaner. As desired, the user can either place the crevice nozzle or the upholstery nozzle on the suction pipe or the suction hose of the vacuum cleaner.

Zum lösbaren Halten der Fugendüse an der Polsterdüse kann die Fugendüse einen vorspringenden Ringabschnitt aufweisen, der in einer mit der Polsterdüse verrasteten Position von den Rastmitteln übergriffen ist.For releasably holding the crevice nozzle to the upholstery nozzle, the crevice nozzle may have a projecting annular portion which is overlapped by the latching means in a latched position with the upholstery nozzle.

Die positionsrichtige Verrastung der Fugendüse an der Polsterdüse kann bspw. mittels einer Nut-/Feder-Verbindung vorgegeben sein. Dabei kann die Nut als eine Aussparung in dem vorspringenden Ringabschnitt der Fugendüse ausgebildet sein. Als Gegenstück ist die Feder als ein sich axial erstreckender Steg an der Innenwand des rohrförmigen Anschlussstutzens der Polsterdüse ausgebildet. Aufgrund der im Wesentlichen rotationssymmetrischen Gestalt der Fugendüse könnte diese von einem Benutzer bspw. in verschiedenen Drehpositionen in den rohrförmigen Anschlussstutzen der Polsterdüse eingeschoben werden. Um jedoch ein positionsgenaues Einsetzen der Fugendüse in die Polsterdüse zu gewährleisten wird die Fugendüse derart an dem rohrförmigen Anschlussstutzen positioniert, dass die Aussparung des vorspringenden Ringabschnitts der Fugendüse mit dem sich axial erstreckenden Steg an der Innenwand des rohrförmigen Anschlussstutzens fluchtet. Nur in dieser gegenseitigen Position von Fugendüse und Polsterdüse kann die Fugendüse in den rohrförmigen Anschlussstutzen axial eingeschoben werden, bis der vorspringende Ringabschnitt der Fugendüse von den Rastmitteln der Polsterdüse übergriffen werden und dadurch die Fugendüse in der Polsterdüse verrastet.The positionally correct locking of the crevice nozzle to the upholstery nozzle can, for example, be predetermined by means of a tongue and groove connection. In this case, the groove may be formed as a recess in the projecting annular portion of the crevice nozzle. As a counterpart, the spring is formed as an axially extending web on the inner wall of the tubular connecting piece of the upholstery nozzle. Due to the substantially rotationally symmetrical shape of the crevice nozzle, this could be inserted by a user, for example, in different rotational positions in the tubular connection piece of the upholstery nozzle. However, in order to ensure a positionally accurate insertion of the crevice nozzle in the upholstery nozzle, the crevice nozzle is positioned on the tubular connection piece, that the recess of the projecting annular portion of the crevice is aligned with the axially extending web on the inner wall of the tubular connecting piece. Only in this mutual position of crevice nozzle and upholstery nozzle, the crevice nozzle can be inserted axially into the tubular connection piece until the projecting annular portion of the crevice nozzle are overlapped by the locking means of the upholstery nozzle and thereby locks the crevice nozzle in the upholstery nozzle.

Zusätzlich kann die Fugendüse mindestens eine, vorzugsweise zwei Rastnasen aufweisen die sich an einer Wand der rückspringenden Aufnahme abstützen. An einer dem Rastmittel zugewandten Seitenwand der Saugdüseneinheit kann mindestens ein vorspringender Abstandshalter vorgesehen sein, der zusammenwirkend mit dem Rastmittel und der mindestens einen Rastnase der Fugendüse die Saugdüseneinheit in einer vorgespannten Lage am Gehäuse des Staubsaugers hält. Nachdem die vorzugsweise als U-förmige Laschen ausgebildeten Rastmittel der Saugdüseneinheit an die Rippe des Staubsaugergehäuses aufgesteckt sind, bewirken die vorspringenden Abstandshalter, dass die Saugdüseneinheit von Polsterdüse und Fugendüse derart gegenüber dem Staubsaugergehäuse verkippt wird, dass die an der Fugendüse vorgesehene mindestens eine Rastnase hinter einen zur Rastnase korrespondierenden Rücksprung verrastet. Damit wird die Saugdüseneinheit in einer vorgespannten Lage am Gehäuse des Staubsaugers gehalten.In addition, the crevice nozzle may have at least one, preferably two latching noses which are supported on a wall of the recessed receptacle. At least one protruding spacer may be provided on a side wall of the suction nozzle unit facing the latching means, which in cooperation with the latching means and the at least one latching lug of the crevice nozzle holds the suction nozzle unit in a prestressed position on the housing of the vacuum cleaner. After the detent means of the suction nozzle unit, which are preferably designed as U-shaped tabs, are attached to the rib of the vacuum cleaner housing, the protruding spacers cause the suction nozzle unit of the upholstery nozzle and crevice nozzle to be tilted relative to the vacuum cleaner housing such that the at least one latching nose provided at the crevice nozzle is behind one latched to the latch nose corresponding recess. Thus, the suction nozzle unit is held in a biased position on the housing of the vacuum cleaner.

Vorteilhafter Weise kann die rückspringende Aufnahme als Griffmulde ausgebildet sein. Bei entnommener Saugdüseneinheit kann der Benutzer den Staubsauger tragen, indem er seine Hand in die rückspringende Aufnahme einführt und in die in der Aufnahme vorgesehene Griffmulde einlegt und den Staubsauger anhebt.Advantageously, the recessed receptacle may be formed as a recessed grip. With the suction nozzle unit removed, the user can carry the vacuum cleaner by inserting his hand into the recessed receptacle and inserting it into the recessed grip provided in the receptacle and lifting the vacuum cleaner.

Vorzugsweise ist am Staubsauger ein weiterer Griff vorgesehen, so dass auch bei in die Aufnahme eingesetzter Saugdüseneinheit der Staubsauger von einem Benutzer getragen werden kann.Preferably, a further handle is provided on the vacuum cleaner, so that even when inserted into the receptacle suction nozzle unit of the vacuum cleaner can be worn by a user.

Ein in Figur 1 ausschnittsweise dargestellter Staubsauger 1 zeigt in perspektivischer Ansicht ein Gehäuse 2. Eine Gehäusekappe 3 sitzt auf einem Gehäuseunterteil 4 des Gehäuses 2 auf und umschließt nicht dargestellte elektrische Komponenten des Staubsaugers 1, wie beispielsweise ein Gebläseaggregat, eine Kabeltrommel oder elektronische Steuerungselemente. In einem mittleren Frontbereich 5 der Bodenfläche des Gehäuseunterteils 4 ist eine Laufrolle 6 in einem schwenkbar an dem Gehäuseunterteil 4 gelagerten Laufrollengehäuse 7 drehbar gelagert. Zur drehbaren Lagerung weist die Laufrolle 6 zwei gegenüberliegende Achszapfen 8 auf, die in zugeordnete, am Laufrollengehäuse 7 angeformte Rastelemente 9 einrasten. Dem Laufrollengehäuse 7 ist im mittleren Frontbereich 5 eine Aufnahme 10 in das Gehäuseunterteil 4 eingeformt vorgelagert. Die Aufnahme 10 ist rückspringend ausgebildet, d.h. sie ist nischenartig hinter die äußere Oberfläche des jeweiligen zugeordneten Gehäuseteils zurückgesetzt und kann in Abwandlung zu dem dargestellten Ausführungsbeispiel an jeder anderen geeigneten Stelle des Gehäuses 2 bzw. eines anderen Bauteils des Staubsaugers 1 vorgesehen sein. Die Aufnahme 10 muss nicht angeformt sein, sondern kann auch als gesondertes Bauteil in das Gehäuse 2 bzw. den Staubsauger 1 integriert sein. Die Aufnahme 10 weist im Ausführungsbeispiel eine Öffnung mit rechteckiger Kontur auf. Je nach Art und Ausgestaltung einer Saugdüseneinheit 12 sind die Konturen der Öffnung 11 und die Kontur der Saugdüseneinheit 12 aufeinander angepasst und können neben der dargestellten Rechteckform auch andere geeignete Formen aufweisen. In der in Figur 1 dargestellten eingesetzten Position der Saugdüseneinheit 12 in das Gehäuseunterteil 4 des Gehäuses 2, schließt ein Wandabschnitt 13 der Saugdüseneinheit 12 flächenbündig mit der Oberfläche des Gehäuseunterteils 4 ab. Trotz eines geringfügig über die Oberfläche des Wandabschnitts 13 vorstehenden rohrförmigen Anschlussstutzens 14 integriert sich die Saugdüseneinheit 12 annähernd vollständig in die Oberfläche des Gehäuseunterteils 4. Eine solche optisch ansprechende und betriebssichere Integration der Saugdüseneinheit 12 in den Staubsauger 1 ist insbesondere auch in eine obenliegende Gehäusekappe 3 von Vorteil.An in FIG. 1 A housing cap 3 is seated on a housing lower part 4 of the housing 2 and surrounds not shown electrical components of the vacuum cleaner 1, such as a blower unit, a cable drum or electronic Controls. In a central front region 5 of the bottom surface of the lower housing part 4, a roller 6 is rotatably mounted in a pivotally mounted on the lower housing part 4 roller housing 7. For rotatable mounting, the roller 6 has two opposite journals 8, which engage in associated, integrally formed on the roller housing 7 locking elements 9. The roller housing 7 is a receptacle 10 in the middle front portion 5 formed in the housing lower part 4 upstream. The receptacle 10 is designed to spring back, ie it is niche-like set behind the outer surface of the respective associated housing part and may be provided in a modification to the illustrated embodiment at any other suitable location of the housing 2 and another component of the vacuum cleaner 1. The receptacle 10 does not have to be formed, but can also be integrated as a separate component in the housing 2 or the vacuum cleaner 1. The receptacle 10 has in the embodiment an opening with a rectangular contour. Depending on the type and configuration of a suction nozzle unit 12, the contours of the opening 11 and the contour of the suction nozzle unit 12 are adapted to each other and can also have other suitable shapes in addition to the illustrated rectangular shape. In the in FIG. 1 shown used position of the suction nozzle unit 12 in the lower housing part 4 of the housing 2, a wall portion 13 of the suction nozzle unit 12 is flush with the surface of the housing lower part 4 from. Despite a slightly above the surface of the wall portion 13 projecting tubular connecting piece 14, the suction nozzle unit 12 integrates almost completely in the surface of the housing base 4. Such visually appealing and reliable integration of the suction nozzle unit 12 in the vacuum cleaner 1 is in particular in an overhead housing cap 3 of Advantage.

Im Ausführungsbeispiel ist die Saugdüseneinheit 12, wie in den Figuren 2 und 3 gezeigt, als eine Polsterdüse 23 ausgebildet, bei der eine Seitenwand des Saugdüsengehäuses 15 den Wandabschnitt 13 bildet. Der geringfügig über die Oberfläche des Wandabschnitts 13 vorstehende rohrförmige Anschlussstutzen 14 weist zwei an seiner Außenwand 16 vorgesehene Halteabschnitte 17 auf. Die Halteabschnitte 17 sind gegenüberliegend an der Außenwand 16 angeformt und weisen eine Kreisabschnittsform auf. Der rohrförmige Anschlussstutzen 14 durchdringt geometrisch den Wandabschnitt 13 der Saugdüseneinheit 12. An den rohrförmige Anschlussstutzen 14 ist ein nichtdargestelltes Saugrohr oder ein Saugschlauch des Staubsaugers 1 ein- bzw. aufsteckbar.In the embodiment, the suction nozzle unit 12, as in the FIGS. 2 and 3 shown as a cushioning nozzle 23 is formed, in which a side wall of the suction nozzle housing 15 forms the wall portion 13. The slightly above the surface of the wall portion 13 projecting tubular connection piece 14 has two provided on its outer wall 16 holding portions 17. The holding portions 17 are formed opposite to the outer wall 16 and have a circular section shape. The tubular connecting piece 14 geometrically penetrates the wall portion 13 of the suction nozzle unit 12. At the tubular connection piece 14 is a not shown suction pipe or a suction hose of the vacuum cleaner 1 on or plugged.

Wie in Figur 3 gezeigt sind an einem der rückspringenden Aufnahme 10 zugewandten Ende des rohrförmigen Anschlussstutzens 14 drei gleichmäßig über den Umfang verteilte Rastungen 18 vorgesehen. Die Rastungen 18 weisen nach innen vorspringende Rastnasen 19 auf, die am freien Ende von federnd an den rohrförmigen Anschlussstutzen 14 angeformten Federzungen 20 vorgesehen sind. Im Ausführungsbeispiel entstehen die Federzungen 20 durch jeweils zwei parallel verlaufende axiale Ausnehmungen 25 in der Seitenwand des rohrförmigen Anschlussstutzens 14. Durch die Rastungen 18 kann eine in die kreisförmige Öffnung des rohrförmigen Anschlussstutzens 14 eingeführte Fugendüse 21 (Figur 4) am Saugdüsengehäuse 15 lösbar befestigt werden.As in FIG. 3 Shown at one of the recessed receptacle 10 facing the end of the tubular connecting piece 14 three uniformly distributed over the circumference notches 18 are provided. The detents 18 have inwardly projecting locking lugs 19, which are provided at the free end of resiliently integrally formed on the tubular connecting piece 14 spring tongues 20. In the embodiment, the spring tongues 20 formed by two parallel axial recesses 25 in the side wall of the tubular connecting piece 14. By the notches 18 can be inserted into the circular opening of the tubular connecting piece 14 crevice nozzle 21 (FIG. FIG. 4 ) are releasably secured to the suction nozzle housing 15.

Wie in Figur 4 gezeigt, besitzt die Fugendüse 21 dazu einen vorspringenden Ringabschnitt 22, der in einer mit der Polsterdüse 23 verrasteten Position (Figur 5) von den Rastungen 18 bzw. von den Rastnasen 19 übergriffen wird. Der vorspringende Ringabschnitt 22 der Fugendüse 21 weist eine nutartige Aussparung 24 auf. Der rohrförmige Anschlussstutzen 14 der Polsterdüse 23 trägt an seiner Innenwand einen sich in axialer Richtung längserstreckenden Steg 26 (Figur 3), welcher in der eingesetzten Position der Fugendüse 21 in die Polsterdüse 23 in der Nut 24 zu liegen kommt. Die Fugendüse 21 trägt an einer Seitenwand vorzugsweise zwei parallel verlaufende nach außen vorspringende Rastnasen 27, die sich in der Aufbewahrungsposition der Saugdüseneinheit 12 in der Aufnahme 10 an einer Wand 28 der Aufnahme 10 abstützen (Figur 6).As in FIG. 4 shown has the crevice nozzle 21 to a projecting annular portion 22 which in a latched with the upholstery nozzle 23 position (FIG. FIG. 5 ) is overlapped by the detents 18 and 19 of the locking lugs. The projecting annular portion 22 of the crevice nozzle 21 has a groove-like recess 24. The tubular connecting piece 14 of the upholstery nozzle 23 carries on its inner wall a longitudinally extending web 26 in the axial direction (FIG. FIG. 3 ), which comes to rest in the inserted position of the crevice nozzle 21 in the upholstery nozzle 23 in the groove 24. The crevice nozzle 21 carries on a side wall preferably two parallel outwardly projecting locking lugs 27 which are supported in the storage position of the suction nozzle unit 12 in the receptacle 10 on a wall 28 of the receptacle 10 ( FIG. 6 ).

In Figur 5 ist in einem vorderen Bereich des Saugdüsengehäuses 15 ein Rastmittel 29 vorzugsweise einteilig angeformt. In der Aufbewahrungsposition (Figur 1) greift das Rastmittel 29 in ein Gegenrastmittel 30 am Gehäuse 2 des Staubsaugers 1 ein. Das Rastmittel 29 besteht vorzugsweise aus zwei U-förmigen Laschen 31, die am Saugdüsengehäuse 15 angeformt sind. Das Gegenrastmittel 30 wird von einer am Gehäuse 2 des Staubsaugers 1 angebrachten Rippe 32 gebildet. In der verrasteten Position umgreifen die U-förmigen Laschen 31 die Rippe 32.In FIG. 5 is in a front region of the suction nozzle 15, a locking means 29 preferably integrally formed. In the storage position ( FIG. 1 ) engages the locking means 29 in a counter-locking means 30 on the housing 2 of the vacuum cleaner 1 a. The latching means 29 preferably consists of two U-shaped tabs 31 which are integrally formed on the suction nozzle housing 15. The counter-locking means 30 is formed by a attached to the housing 2 of the vacuum cleaner 1 rib 32. In the latched position, the U-shaped tabs 31 engage around the rib 32.

Schließlich sind an einer den U-förmigen Laschen 31 zugewandten Seitenwand 33 der Polsterdüse 23 Abstandshalter 34 vorgesehen. Die Abstandshalter 34 sind als linsenförmig vorstehende Noppen ausgebildet und vorzugsweise an die Seitenwand 33 angeformt. In der Aufbewahrungsposition sitzen die U-förmigen Laschen 31 auf der Rippe 32 auf. Die Abstandshalter 34 stützen sich in dieser Position an einer Seitenwand der Rippe 32 derart ab, dass die Saugdüseneinheit 12 geringfügig in Pfeilrichtung P um die fiktive Drehachse A in Nähe der U-förmigen Laschen 31 gekippt wird. Dadurch werden die Rastnasen 27 in ihre vorspringende Richtung gedrückt, so dass, wie in Figur 6 dargestellt, die Rastnasen 27 vorgespannt hinter der Wand 28 verrasten. Die Wand 28 ist Teil eines Stegabschnittes 35, der den Griffbereich einer Griffmulde 36 bildet.Finally, spacers 34 are provided on a side wall 33 of the upholstery nozzle 23 facing the U-shaped tabs 31.
