Description

Staubsauger mit einem Deckelentriegelungselement Vacuum cleaner with a lid unlocking element
Die Erfindung betrifft einen Staubsauger gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a vacuum cleaner according to the preamble of claim 1.
Ein auf dem Markt befindlicher Staubsauger weist ein Gehäuse auf, in dem eine Staubsammelraum angeordnet ist, der durch einen Staubraumdeckel verschließbar ist, der zum Tragen des Staubsaugers von Hand einen stegartigen Griffabschnitt aufweist, der an eine Ausnehmung des Staubraumdeckels angrenzt, in die ein Entriegelungselement eines Rastelements hineinragt, das mit einem Gegenrastelement des Gehäuses zusammenwirkt, um den Staubraumdeckel in einer Schließposition zu halten.A marketed in the vacuum cleaner has a housing in which a dust collection chamber is arranged, which is closed by a dust compartment lid, which has a web-like handle portion for supporting the vacuum cleaner by hand, which adjoins a recess of the dust chamber lid, in which an unlocking a Detent element projects, which cooperates with a counter-latching element of the housing to hold the dust chamber cover in a closed position.
Bei diesem Staubsauger nach dem Stand der Technik ist der Staubraumdeckel schwenkbar am Gehäuse gelagert. Durch öffnen des Staubraumdeckels wird der Staubraum zugänglich um einen gefüllten Staubbeutel entnehmen und einen neuen leeren Staubbeutel einsetzen zu können. An einem dem Scharniergelenk gegenüberliegenden Ende des Staubraumdeckels ist ein stegartiger Griff an dem Staubraumdeckel angeformt. Damit der stegartige Griff von einer Hand umgriffen werden kann, ist in der Wand des Staubraumdeckels eine Grifföffnung erforderlich. In die Grifföffnung ragt das Entriegelungselement durch dessen Betätigung ein Rastelement betätigt wird, um den Staubraumdeckel öffnen zu können.In this prior art vacuum cleaner, the dust compartment lid is pivotally mounted on the housing. By opening the dust compartment lid, the dust compartment is accessible to remove a filled dust bag and to be able to use a new empty dust bag. At a hinge joint opposite end of the dust chamber lid, a web-like handle on the dust chamber cover is formed. So that the web-like handle can be grasped by one hand, a handle opening is required in the wall of the dust chamber lid. In the handle opening the unlocking protrudes by the actuation of a locking element is actuated to open the dust chamber cover can.
Nachteilig an diesem Stand der Technik ist es jedoch, dass die Grifföffnung verhältnismäßig groß gestaltet sein muss. Dies hat im Wesentlichen zwei Gründe. Zum Einen muss die Grifföffnung so bemessen sein, dass beim Umgreifen des stegartigen Griffabschnitts vier Finger einer Hand die Grifföffnung durchgreifen. Zum Anderen soll die Grifföffnung deutlich größer gestaltet werden als es nur zum Durchgreifen der vier Finger nötig wäre. Es ist nämlich sicherzustellen, dass beim Durchgreifen der Grifföffnung mit den Fingern das Entriegelungselement nicht unbeabsichtigt betätigt und das Rastelement gelöst wird. Dies hätte nämlich zur Folge, dass beim Durchgreifen der Grifföffnung zum Tragen des Staubsaugers die Entriegelung des Staubraumdeckels versehentlich betätigt wird und sich der Staubraumdeckel öffnet während der Staubsauger getragen wird. Aufgabe der Erfindung ist es, einen Staubsauger mit einer verbesserten Deckelverriegelung zu schaffen.A disadvantage of this prior art, however, is that the handle opening must be made relatively large. This has two main reasons. On the one hand, the handle opening must be dimensioned so that when grasping the web-like handle section four fingers of one hand reach through the handle opening. On the other hand, the handle opening should be made much larger than it would only be necessary to reach through the four fingers. It is namely to ensure that when reaching through the handle opening with the fingers, the unlocking element is not actuated unintentionally and the locking element is released. This would have the consequence that when reaching through the handle opening for carrying the vacuum cleaner, the unlocking of the dust chamber lid is accidentally operated and the dust chamber lid opens while the vacuum cleaner is worn. The object of the invention is to provide a vacuum cleaner with an improved lid lock.
Erfindungsgemäß wird diese Aufgabe bei einem gattungsgemäßen Staubsauger dadurch gelöst, dass das Entriegelungselement flächenbündig in die Kontur desAccording to the invention, this object is achieved in a generic vacuum cleaner in that the unlocking flush with the contour of the

Staubraumdeckels geschaffen werden kann. In dem eine Durchgrifföffnung verhindert ist, kann sichergestellt werden, dass beim Tragen des Staubsaugers von Hand nicht versehendlich das Entriegelungselement betätigt und die Deckelverriegelung ausgelöst wird. Zum Tragen des Staubsaugers ist dann erfindungsgemäß eine Tragemulde vorgesehen, die von Fingern einer Hand hintergriffen werden kann, ohne durch eineDust space cover can be created. In which a penetration opening is prevented, it can be ensured that when carrying the vacuum cleaner by hand not accidentally actuates the unlocking element and the lid lock is triggered. To carry the vacuum cleaner according to the invention then a support trough is provided, which can be engaged behind by fingers of one hand, without a
Öffnung im Staubraumdeckel hindurchgreifen zu müssen.To have to reach through opening in the dust chamber cover.
In der bevorzugten Ausgestaltung der Erfindung ist das Entriegelungselement einteilig mit dem Staubraumdeckel ausgebildet. Entriegelungselement und Staubraumdeckel können vorzugsweise aus Kunststoff im Spritzgußverfahren hergestellt sein. Durch ein direktes Anformen des Entriegelungselements an den Staubraumdeckel reduziert sich die Teilevielfalt bei der Herstellung und ein Montageschritt für die Befestigung des Entriegelungselements an dem Staubraumdeckel kann entfallen, was die Herstellung des Staubsaugers kostengünstig macht.In the preferred embodiment of the invention, the unlocking element is formed integrally with the dust chamber cover. Entriegelungselement and dust chamber cover may preferably be made of plastic by injection molding. By a direct molding of the unlocking of the dust chamber lid reduces the variety of parts in the production and an assembly step for fixing the unlocking on the dust chamber cover can be omitted, which makes the production of the vacuum cleaner cost.
Das Entriegelungselement kann zur Bildung einer beweglichen Betätigungszunge unter Belassen eines über einen Teil seines Umfangs zwischen Entriegelungselement undThe unlocking may be to form a movable actuating tongue while leaving a part of its circumference between the unlocking and

Entriegelungselement. Der Trennspalt kann sehr klein gewählt werden. Alternativ könnte bei größeren Spalten eine dichtende Einlage aus Weichkunststoff bzw. Elastomer in den Spalt eingelegt sein oder im Zweikomponenten-Spritzgußverfahren direkt an den Staubraumdeckel angespritzt sein. Die freie Kante des Entriegelungselements könnte auch die Ausnehmung des Staubraumdeckels hintergreifen, derart, dass der Trennspalt für einen Beobachter von außen optisch geschlossen erscheint.Unlocking. The separation gap can be chosen very small. Alternatively, in the case of larger gaps, a sealing insert made of soft plastic or elastomer could be inserted into the gap or molded directly onto the dust chamber cover in a two-component injection molding process. The free edge of the unlocking could also engage behind the recess of the dust chamber cover, such that the separation gap for an observer from the outside appears optically closed.
Ist das Entriegelungselement als Betätigungszunge ausgebildet, so kann diese um eine Grundlinie im Übergangsbereich zwischen Entriegelungselement und Staubraumdeckel schwenkbar sein. Vorzugsweise ist dieser Übergangsbereich filmscharnierartig ausgebildet. Zur Ausbildung des Filmscharniers kann der Straubraumdeckel entlang dieser Grundlinie, die vorzugsweise eine Sehnenlinie ist, in seiner Wandstärke reduziert sein.If the unlocking element is designed as an actuating tongue, then this can be pivotable about a baseline in the transition region between the unlocking element and the dust chamber cover. Preferably, this transition region is formed like a film hinge. To form the film hinge of the Straubraumdeckel along this baseline, which is preferably a chord line, be reduced in its wall thickness.
In einer bevorzugten Ausgestaltung ist das Rastelement an einer der Betätigungszunge gegenüberliegenden Seite des Übergangsbereichs, also der Grundlinie bzw. der Sehnenlinie an der Innenseite des Staubraumdeckels angeordnet und von mindestens einem Vorsprung an der Innenseite der Betätigungszunge auslösbar. Durch diese Gestaltung wird das Rastelement, welches hinter einem Gegenrastelement am Gehäuse hintergreift konstruktiv von dem Betätigungselement bzw. der Betätigungszunge getrennt.In a preferred embodiment, the latching element is arranged on one of the actuating tongue opposite side of the transition region, ie the base line or the chord line on the inside of the dust chamber cover and triggered by at least one projection on the inside of the actuating tongue. By this design, the locking element, which engages behind a counter-locking element on the housing constructively separated from the actuating element or the actuating tongue.
Wird zwischen Rastelement und Vorsprung ein Spalt belassen, so kann konstruktiv erreicht werden, dass eine geringfügige Bewegung der Betätigungszunge, beispielsweise durch versehendliches leichtes Drücken der Betätigungszunge noch keine Entriegelung des Staubraumdeckels bewirkt. In diesem Fall kann die Betätigungszunge je nachIf a gap is left between the detent element and the projection, then it can be achieved structurally that a slight movement of the actuating tongue, for example due to accidental slight pressing of the actuating tongue, does not cause any unlocking of the dust chamber cover. In this case, the operating tongue may vary depending on
Spaltweite mehr oder wenig geringfügig schwenken ohne das Rastelement zu berühren.Swing the gap more or less slightly without touching the locking element.
Erst durch weitergehendes Drücken der Betätigungszunge mit deutlicher Kraft wird dann das Rastelement mittels des Vorsprungs bzw. der Vorsprünge entriegelt. Durch dieseOnly by further pressing the actuating tongue with clear force then the locking element is unlocked by means of the projection or the projections. Through this

Thus, the reliability of the lid unlocking is ensured even with improper operation by a user.
Der Staubraumdeckel kann optional zum Tragen des Staubsaugers von Hand einen Griffabschnitt aufweisen, der sich zwischen einer freien Kante des Staubraumdeckels und dem Entriegelungselement erstreckt. Dieser Griffabschnitt ist vorzugsweise als Tragemulde ausgebildet, derart, dass keine Öffnung vorhanden ist, durch die Finger einer Hand beim Tragen hindurchgreifen könnten. Die erfindungsgemäße Tragemulde ist so gestaltet, dass die Finger einer Hand vielmehr allenfalls von unten gegen die Betätigungszunge des Entriegelungselements drücken und somit die Verriegelung eher unterstützen als ein unbeabsichtigtes Lösen bewirken könnten.The dust compartment lid may optionally have a handle portion for carrying the vacuum cleaner by hand extending between a free edge of the dust compartment lid and the unlocking member. This handle portion is preferably formed as a support trough, such that no opening is present, could reach through the fingers of a hand while wearing. The support trough according to the invention is designed so that the fingers of a hand rather press at most from below against the actuating tongue of the unlocking and thus support the lock rather than an unintentional release could cause.
Der Staubraumdeckel kann zusätzlich mindestens einen Vorsprung mit einer Seitenkante aufweist, die in einer geschlossenen Lage des Staubraumdeckels an einer Haltewand des Gehäuses anliegt. Durch diese Anlage der Seitenkante an der Haltewand ist der Staubraumdeckel zusätzlich fixiert, derart, dass eine Stau brau mdeckelbewegung verhindert ist, die ein Herausrutschen des Rasthakens bzw. der Zähne von dem Gegenrasthaken verursachen könnte. Hierdurch wird eine erhöhte Sicherheit gegen Lösen der Deckelverriegelung geschaffen. Es zeigen:The dust chamber cover may additionally have at least one projection with a side edge which rests against a retaining wall of the housing in a closed position of the dust chamber cover. By this system, the side edge of the retaining wall of the dust chamber lid is additionally fixed, such that a congestion brewing mdeckelbewegung is prevented, which could cause slipping out of the latching hook and the teeth of the Gegenrasthaken.

Ein in Figur 1 in der Draufsicht dargestellter Staubsauger 1 weist ein Gehäuse 2 auf, das von einem Staubraumdeckel 3 verschlossen ist. Im Staubraumdeckel 3 ist eine Ansaugöffnung 4 eingebracht, über die von einer Saugdüse über ein Saugrohr und/oder Saugschlauch staubbeladene Luft angesaugt wird. Die Ansaugöffnung 4 ist zum Ankoppeln eines Schlauchstutzens (nicht dargestellt) ausgebildet. In Nähe der Ansaugöffnung 4 ist ein Tragegriff 5 an den Staubraumdeckel 3 mit angeformt. Der Tragegriff 5 ist bügelartig geformt und begrenzt eine im Staubraumdeckel 3 vorgesehene Grifföffnung 6, die in ihrer Lage und Größe zum Durchgreifen von vier Fingern einer Hand ausgebildet ist. Der Staubraumdeckel 3 ist um eine Schwenkachse 7 schwenkbar am Gehäuse 2 gelagert. Die Schwenkachse 7 verläuft im wesentlichen parallel zur Längserstreckung des Tragegriffs 5. Der Staubraumdeckel 3 trägt außer der Ansaugöffnung 4 noch einen weiteren kreisförmigen Durchbruch 8, über den ein im Gehäuse 2 drehbewegliches und axial zu drückendes Betätigungselement 9 zum Ein- und Ausschalten, sowie zur Leistungssteuerung zugänglich ist. Zumindest annähernd koaxial zum Mittelpunkt des kreisförmigen Durchbruchs 8 verlaufend sind kreisbogenförmige Lüftungsschlitze 10 in den Staubraumdeckel 3 integriert, über die gefilterte Abluft ausgeblasen wird. In einem mittleren Bereich des Staubraumdeckels 3 ist ein Fenster 11 einer Filterwechselanzeige positioniert.A vacuum cleaner 1 shown in Figure 1 in plan view has a housing 2 which is closed by a dust chamber cover 3. In the dust chamber cover 3, a suction port 4 is introduced, is sucked on the dust-laden air from a suction nozzle via a suction pipe and / or suction hose. The suction port 4 is designed for coupling a hose nozzle (not shown). In the vicinity of the suction port 4, a carrying handle 5 is integrally formed on the dust chamber cover 3 with. The carrying handle 5 is bow-shaped and defines a provided in the dust chamber cover 3 handle opening 6, which is formed in position and size for reaching through four fingers of a hand. The dust chamber cover 3 is mounted pivotably about a pivot axis 7 on the housing 2. The pivot axis 7 extends substantially parallel to the longitudinal extension of the carrying handle 5. The dust chamber cover 3 carries out of the Suction opening 4 still another circular opening 8, via which a rotatable in the housing 2 and axially to be pressed actuator 9 for switching on and off, and for power control is accessible. At least approximately coaxial with the center of the circular aperture 8 extending arcuate ventilation slots 10 are integrated into the dust chamber cover 3, is blown through the filtered exhaust air. In a central region of the dust chamber cover 3, a window 11 of a filter change indicator is positioned.
An einem dem Tragegriff 5 gegenüberliegenden Ende des Staubraumdeckels 3 ist eine Tragemulde 12 an einer freien Kante des Staubraumdeckels 3 angeformt. Die Tragemulde 12 ist rinnenartig nach außen gebogen ausgebildet, so dass die Tragemulde 12 von vier Fingern einer Hand hintergriffen werden kann. Beim Hintergreifen der Tragemulde 12 mit vier Fingern einer Hand kommt bei üblicher Handhabung der Daumen einer Hand auf der Oberseite des Staubraumdeckels 3 zu liegen. In diesem Liegebereich des Daumens ist ein erfindungsgemäßes Entriegelungselement 13 positioniert. Das Entriegelungselement 13 weist eine Betätigungsfläche 14 auf, die zumindest annähernd flächenbündig mit der Oberfläche des Staubraumdeckels 3 verläuft. Das Entriegelungselement 13 ist zungenförmig gestaltet und wird durch einen vorzugsweise parabelförmig verlaufenden Trennspalt 15 von dem Staubraumdeckel 3 optisch abgetrennt. Das Entriegelungselement 13 ist entlang einer Sehnenlinie 16 zwischen den Endpunkten des parabelförmig verlaufenden Trennspaltes 15 filmschamierartig schwenkbar.At a handle 5 opposite end of the dust chamber cover 3, a support trough 12 is integrally formed on a free edge of the dust chamber cover 3. The support trough 12 is formed like a trough bent outwards, so that the support trough 12 can be engaged behind by four fingers of one hand. When grasping the carrying trough 12 with four fingers of one hand, the thumb of one hand comes to rest on the top side of the dust space cover 3 with conventional handling. In this lying area of the thumb, an unlocking element 13 according to the invention is positioned. The unlocking element 13 has an actuating surface 14 which extends at least approximately flush with the surface of the dust chamber cover 3. The unlocking element 13 is designed tongue-shaped and is optically separated by a preferably parabolic separating gap 15 of the dust chamber cover 3. The unlocking element 13 is pivotable along a chord line 16 between the end points of the parabolic separating gap 15 in a film-like manner.
Das Entriegelungselement 13 ist in Figur 2 in einer perspektivischen Ansicht auf einen Ausschnitt des Staubraumdeckels deutlicher gezeigt. An der Betätigungsfläche 14 ist ein Schriftzug 17 angebracht, der einen Benutzer auf das Entriegeln des Staubraumdeckels 3 durch Drücken der Betätigungsfläche 14 hinweist. Erfindungsgemäß soll das Entriegeln durch Drücken mittels eines Daumens einer Hand erfolgen können. Die weiteren vier Finger einer Hand unterstützen diese Entriegelungsbewegung dadurch, dass die vier Finger einer Hand die Tragemulde von der Unterseite des Staubraumdeckels 3 hintergreifen. Um dem drückenden Daumen einen sicheren Halt zu bieten, ist die Oberfläche der Betätigungsfläche 14 strukturiert, so dass ein Abrutschen verhindert ist. Im Ausführungsbeispiel wird die Oberflächenstruktur durch eine Vielzahl von kugelabschnittsförmigen Noppen 18 gebildet, die eine unebene Oberfläche auf der Betätigungsfläche 14 bilden, damit der Daumen Halt findet und somit ein Abrutschen zuverlässig verhindert ist. Die Anbindung des Entriegelungselements 13 an den Staubraumdeckel 3 erfolgt durch direktes Anformen. Entlang der Sehnenlinie 16 verläuft im wesentlichen die Biegeachse, um die das Entriegelungselement 13 schwenkbar und nach innen zu drücken ist. Entlang der Sehnenlinie 16 kann die Materialdicke ausgedünnt sein, um ein Filmscharnier auszubilden. Bei ausreichender Elastizität des Werkstoffes, wie beispielsweise duktiler Kunststoff, für Entriegelungselement 13 und Staubraumdeckel 3 kann ein scharnierartiges Schwenken auch bei konstanter Wandstärke möglich sein, ohne eine filmschamierartige Ausdünnung zu benötigen.The unlocking element 13 is shown more clearly in Figure 2 in a perspective view of a section of the dust chamber cover. On the actuating surface 14, a lettering 17 is attached, which indicates a user to unlock the dust chamber cover 3 by pressing the actuating surface 14. According to the unlocking should be able to be done by pressing a thumb of a hand. The other four fingers of a hand support this unlocking movement in that the four fingers of one hand engage behind the support trough from the bottom of the dust chamber cover 3. In order to provide the pushing thumb with a secure hold, the surface of the actuating surface 14 is structured, so that slipping is prevented. In the exemplary embodiment, the surface structure is formed by a plurality of spherical segment-shaped nubs 18 having an uneven surface on the Forming actuating surface 14, so that the thumb finds support and thus slipping is reliably prevented. The connection of the unlocking element 13 to the dust chamber cover 3 is effected by direct molding. Along the chord line 16 extends substantially the bending axis, around which the unlocking element 13 is to be pressed pivotally and inwardly. Along the chord line 16, the material thickness may be thinned to form a film hinge. With sufficient elasticity of the material, such as ductile plastic, for unlocking element 13 and dust chamber cover 3, a hinge-like pivoting can be possible even with a constant wall thickness, without requiring a filmschamierartige thinning.
In Figur 3 ist eine perspektivische Ansicht von unten auf einen Ausschnitt des Staubraumdeckels 3 mit integriertem Entriegelungselement 13 gezeigt. Im Vordergrund ist die Rückseite der Tragemulde 12 dargestellt. Die Tragemulde 12 weist eine Vielzahl von Rippen 19 auf, die zur Versteifung der rinnförmig gebogenen Tragemulde 12 dienen. An der Unterseite des Entriegelungselements 13 sind zwei gegenüberliegende, parallel zueinander ausgerichtete Innenlaschen 20 angeformt, die zwei im wesentlichen senkrecht zur inneren Oberfläche des Entriegelungselements 13 nach Innen gerichtete VorsprüngeFIG. 3 shows a perspective view from below of a section of the dust compartment cover 3 with integrated unlocking element 13. In the foreground, the back of the support trough 12 is shown. The support trough 12 has a plurality of ribs 19, which serve for stiffening the trough-shaped curved trough 12. On the underside of the unlocking element 13, two opposite, parallel aligned inner plates 20 are formed, the two substantially perpendicular to the inner surface of the unlocking element 13 inwardly directed projections
21 bilden. An der dem Trennspalt 15 gegenüberliegenden Seite der Sehnenlinie 16 ist ein Rastelement 22 an der Innenseite des Staubraumdeckels 3 angeformt. Das Rastelement21 form. At the separation gap 15 opposite side of the chord line 16, a locking element 22 is integrally formed on the inside of the dust chamber cover 3. The locking element
22 weist einen annähernd rechteckigen Wandabschnitt 23 auf, der mit seiner einen Seitenkante an die innere Oberfläche des Staubraumdeckels 3 angeformt ist. Der22 has an approximately rectangular wall portion 23 which is integrally formed with its one side edge to the inner surface of the dust chamber cover 3. Of the
Wandabschnitt 23 ragt senkrecht von der inneren Oberfläche des Staubraumdeckels 3 vor. Am freien Ende des Wandabschnitt 23 sind zwei rinnenförmige Zähne 24 angeformt, die Rasthaken 25 des Rastelements 22 bilden. Jede der beiden Rasthaken 25 ist über einen Steg 26 mit einem der Innenlaschen 20 verbunden. Zwischen Innenlasche 20 und Wandabschnitt 23 ergibt sich unterhalb des Stegs 26 ein freier Spalt 27, der eine Biegeelastizität des Rastelements 22 trotz Anbindung an die Innenlaschen 20 aufrecht erhält. Außerhalb der Kontur des Trennspaltes 15 sind zwei parallel zu den Innenlaschen 20 verlaufende Außenlaschen 28 an den Staubraumdeckel 3 angeformt. Die Außenlaschen 28 springen im wesentlichen senkrecht von der inneren Oberfläche des Staubraumdeckels 3 vor. In einer geschlossenen Lage des Staubraumdeckels 3 am Gehäuse 2 liegen Seitenkanten 29 der Außenlaschen 28 an einer Haltewand 30 in der Nähe eines Gegenrastelements 31 am Gehäuse 2 an. Eine perspektivische Ansicht auf einen Ausschnitt des Gehäuses 2 mit dem angeformten Gegenrastelement 31 ist in Figur 4 gezeigt. Das Gegenrastelement 31 ist an die Oberseite des Gehäuses 2 angeformt und wird gebildet durch einen Dom 32, der rampenartig geformt ist und an dessen oberem freien Ende ein Gegenrasthaken 33 auskragend angeformt ist. In einer geschlossenen Lage des Staubraumdeckels 3 verrasten der Zahn 24 bzw. die Zähne 24 an dem hinterschnittenen Gegenrasthaken 33. Unterhalb des Gegenrasthakens 33 ist ein im wesentlichen quaderförmiger Lagerbock 34 angeordnet. Der Lagerbock 34 ist an die Oberfläche des Gehäuses 2 angeformt und in einem mittleren Bereich unterhalb des Gegenrasthakens 33 zur Bildung einer Aufnahmetasche 35 ausgespart. In die Aufnahmetasche 35 taucht in der geschlossenen Lage des Staubraumdeckels 3 das freie Ende des Rastelements 22 d.h. die Zähne 24 bzw. der Rasthaken 25 ein. Mittels zweier gegenüberliegender Innenwände 36 der Aufnahmetasche 35 wird das Rastelement 22 dadurch geführt und zentriert, dass seitliche Kanten des Wandabschnitts 23 des Rastelement 22 an den Innenwänden 36 anliegen, wenn der Staubraumdeckel 3 geschlossen ist. In einem Frontbereich des Lagerbocks 34 sind Haltewände 30 ausgebildet, an denen die Seitenkanten 29 der Außenlaschen 28 in der geschlossenen Lage des Staubraumdeckels 3 anliegen.Wall section 23 protrudes perpendicularly from the inner surface of the dust chamber cover 3. At the free end of the wall portion 23, two groove-shaped teeth 24 are formed, forming the latching hooks 25 of the locking element 22. Each of the two latching hooks 25 is connected via a web 26 with one of the inner flaps 20. Between inner tab 20 and wall portion 23 results below the web 26, a free gap 27, which maintains a bending elasticity of the locking element 22 despite connection to the inner plates 20. Outside the contour of the separating gap 15, two outer flaps 28 extending parallel to the inner flaps 20 are integrally formed on the dust chamber cover 3. The outer plates 28 project substantially perpendicularly from the inner surface of the dust chamber cover 3. In a closed position of the dust chamber cover 3 on the housing 2 are side edges 29 of the outer plates 28 on a retaining wall 30 in the vicinity of a counter-latching element 31 on the housing 2 at. A perspective view of a section of the housing 2 with the molded counter-latching element 31 is shown in FIG. The counter-latching element 31 is integrally formed on the upper side of the housing 2 and is formed by a dome 32, which is ramp-shaped and at the upper free end of a counter-latching hook 33 is formed projecting. In a closed position of the dust chamber cover 3, the tooth 24 or the teeth 24 latch on the undercut counter-latch hook 33. Underneath the counter-latch hook 33, a substantially block-shaped bearing block 34 is arranged. The bearing block 34 is integrally formed on the surface of the housing 2 and recessed in a central region below the Gegenrasthakens 33 to form a receiving pocket 35. In the receiving pocket 35 immersed in the closed position of the dust chamber cover 3, the free end of the locking element 22 that is, the teeth 24 and the latch hook 25 a. By means of two opposite inner walls 36 of the receiving pocket 35, the locking element 22 is guided and centered by that lateral edges of the wall portion 23 of the locking element 22 abut against the inner walls 36 when the dust chamber cover 3 is closed. In a front region of the bearing block 34 retaining walls 30 are formed, against which the side edges 29 of the outer plates 28 in the closed position of the dust chamber cover 3.
Eine Teilschnittansicht durch das Gehäuse 2 und dem Staubraumdeckel 3 mit dem erfindungsgemäßen Rastelement 22 und dem erfindungsgemäßen Gegenrastelement 31 ist in Figur 5 in der Schließposition des Staubraumdeckels 3 gezeigt. In dieser Ansicht sind auch eine der Innenlaschen 20 und eine der Außenlaschen 28 dargestellt. Der Gegenrasthaken 33 übergreift in der geschlossenen Lage des Staubraumdeckels 3 die Zähne 24 des Rasthakens 25 und hält dadurch den Staubraumdeckel in seiner geschlossenen Lage. Durch diese Verrastung ist auch sichergestellt, dass beim Tragen des Staubsaugers an der Tragemulde 12 sich der Staubraumdeckel 3 nicht unbeabsichtigt öffnet. Die gegenseitige Lage und Ausrichtung von Gegenrasthaken 33 und Rasthaken 25 ist so gewählt, dass bei einer durch das Tragen an der Griffmulde 12 durch die Schwerkraft induzierte Kraft kein Lösen der Rastverbindung verursachen kann, sondern vielmehr diese Kraft zu einem verstärkten Ineinandergreifen von Gegenrasthaken 33 und Rasthaken 25 führt, was die Festigkeit und Zuverlässigkeit gegen Lösen erhöht.A partial sectional view through the housing 2 and the dust chamber cover 3 with the latching element 22 according to the invention and the counter-latching element 31 according to the invention is shown in FIG. 5 in the closed position of the dust chamber cover 3. In this view, one of the inner plates 20 and one of the outer plates 28 are shown. The Gegenrasthaken 33 engages in the closed position of the dust chamber cover 3, the teeth 24 of the latching hook 25 and thereby holds the dust chamber cover in its closed position. By this locking is also ensured that when carrying the vacuum cleaner on the support trough 12, the dust chamber lid 3 does not open unintentionally. The mutual position and orientation of the counter-latching hooks 33 and latching hooks 25 is selected such that a force induced by gravity on the recessed grip 12 can not cause disengagement of the latching connection, but rather this force results in increased engagement of the counter-latching hooks 33 and latching hooks 25 leads, which increases the strength and reliability against loosening.
Eine Teilschnittansicht durch Gehäuse 2 und Staubraumdeckel 3 in einer zu Rastelement 22 und Gegenrastelement 31 nach Figur 5 versetzt liegenden Ebene ist in Figur 6 gezeigt. In dieser Schnittansicht ist dargestellt, wie die Seitenkante 29 einer Außenlasche 28 an der Haltewand 30 des Lagerbocks 34 anliegt. Durch diese Anlage der Seitenkante 29 an der Haltewand 30 ist der Staubraumdeckel 3 zusätzlich fixiert, derart, dass eine Staubraumdeckelbewegung verhindert ist, die ein Herausrutschen des Rasthakens 25 bzw. der Zähne 24 von dem Gegenrasthaken 33 verursachen könnte. Hierdurch wird eine erhöhte Sicherheit gegen Lösen der Deckelverriegelung geschaffen. A partial sectional view through housing 2 and dust chamber cover 3 in a plane offset from latching element 22 and counter-latching element 31 according to FIG. 5 is shown in FIG. In this sectional view is shown how the side edge 29 of an outer flap 28 rests against the retaining wall 30 of the bearing block 34. By this system, the side edge 29 on the retaining wall 30 of the dust chamber cover 3 is additionally fixed, such that a Staubraumdeckelbewegung is prevented, which could cause a slipping out of the latching hook 25 and the teeth 24 of the Gegenrasthaken 33. As a result, increased security against loosening the lid lock is created.
