Description

Die Erfindung betrifft einen Staubsauger mit einem durch einen Deckel verschließbaren Staubraum, in dem ein mit einer Versteifungsplatte versehener Filterbeutel an einem schwenkbar angeordneten Halteteil, welches durch Federkraft bei nicht eingesetztem Filterbeutel in eine im Schließweg des Deckels liegende Stellung geschwenkt ist, befestigbar ist, bei dem ferner am Deckel ein durch die in der Versteifungsplatte vorgesehene Einlaßöffnung hindurchgreifender Saugstutzen vorgesehen ist.The invention relates to a vacuum cleaner with a dust chamber which can be closed by a lid, in which a filter bag provided with a stiffening plate can be fastened to a pivotably arranged holding part, which is pivoted by spring force when the filter bag is not inserted into a position lying in the closing path of the lid, in which there is also provided on the cover a suction nozzle which extends through the inlet opening provided in the stiffening plate.

Ein solcher Staubsauger ist durch die DE-A-2730894 bekannt. Bei diesem Staubsauger sind an gegenüberliegenden Seitenwänden des Saugraumes Steckaufnahmen vorgesehen, in die jeweils ein Arm eines zweiarmigen Lagerbockes eingesteckt ist. An diesem Lagerbock ist ein an seinem Ende rechtwinkelig abgebogener Hebel angelenkt. Der zweite nach oben ragende Arm des Lagerbockes dient als Anschlag für den Hebel, wenn dieser in die Betriebslage geschwenkt wird. Das rechtwinkelig abgebogene Ende des Hebels dient in der Betriebslage als Auflage für die Versteifungsplatte des Filterbeutels. An dem abgebogenen Ende jedes Hebels ist noch ein Zapfen angeformt, der beim Auflegen der Versteifungsplatte in eine entsprechende Ausnehmung der Versteifungsplatte eingreift. An dem Hebel greift eine Feder an, die den Hebel nach außen schwenkt, sobald die Versteifungsplatte von dem abgebogenen Ende abgehoben wird. Der Hebel ragt dann nach außen und der Deckel kann nicht auf den Staubraum aufgesetzt werden.Such a vacuum cleaner is known from DE-A-2730894. In this vacuum cleaner plug receptacles are provided on opposite side walls of the suction chamber, into each of which an arm of a two-armed bearing block is inserted. A lever is bent at a right angle at this end bracket. The second upstanding arm of the pedestal serves as a stop for the lever when it is pivoted into the operating position. The right-angled end of the lever serves as a support for the stiffening plate of the filter bag in the operating position. At the bent end of each lever a pin is formed, which engages in a corresponding recess of the stiffening plate when placing the stiffening plate. A spring engages the lever, which pivots the lever outwards as soon as the stiffening plate is lifted from the bent end. The lever then protrudes outwards and the lid cannot be placed on the dust compartment.

Bei diesem Staubsauger sind der Lagerbock und der angelenkte Hebel speziell für die Funktion als Sperrelement ausgebildet. Beim Einsetzen eines neuen Filterbeutels müssen die beiden gegenüberliegenden Hebel mit beiden Händen nach innen geschwenkt und dann die Versteifungsplatte mit den Ausnehmungen auf die Zapfen aufgesteckt werden. Da die Versteifungsplatte nach dem Aufstecken auf die Zapfen in ihrer Lage verbleibt, kann der Deckel mit dem angeformten und in die Einlaßöffnung der Versteifungsplatte eingreifenden Saugstutzen nur in senkrechter Richtung auf den Straubraum aufgesetzt werden. Dies muß ebenfalls beidhändig geschehen.In this vacuum cleaner, the bracket and the articulated lever are specially designed to function as a locking element. When inserting a new filter bag, the two opposite levers must be swiveled inwards with both hands and then the stiffening plate with the recesses must be attached to the pins. Since the stiffening plate remains in its position after being plugged onto the pegs, the cover with the molded-on suction nozzle which engages in the inlet opening of the stiffening plate can only be placed in the vertical direction onto the stowage chamber. This must also be done with both hands.

Bei einem aus der US-A-27 42105 bekannten Staubsauger ist ebenfails ein gesonderter Schwenkhebel als Sperrelement vorgesehen. Der Schwenkhebel ist entweder am Staubsaugergehäuse oder an dem den Staubraum abschließenden Deckel angelenkt. Durch eine Feder wird der Schwenkhebel beim Öffnen des Deckels in seine Sperrlage geschwenkt. Beim Schließen des Deckels wird der Sperrhebel durch die Versteifungsplatte des Filterbeutels aus seiner Sperrlage gedrängt und der Deckel kann ohne Behinderung geschlossen werden. Ist dagegen kein Filterbeutel in den Staubraum eingesetzt, verbleibt der Schwenkhebel in der Sperrlage und verhindert ein Schließen des Deckels. Auch bei diesem Staubsauger dient der Schwenkhebel nur als Sperrelement und erfüllt keine weitere Funktion.In a vacuum cleaner known from US-A-27 42105, a separate pivot lever is also provided as a locking element. The swivel lever is either articulated on the vacuum cleaner housing or on the cover that closes off the dust chamber. The spring is pivoted into its locked position when the cover is opened. When the lid is closed, the locking lever is pushed out of its locked position by the stiffening plate of the filter bag and the lid can be closed without hindrance. If, on the other hand, no filter bag is inserted in the dust chamber, the swivel lever remains in the locked position and prevents the lid from closing. With this vacuum cleaner too, the swivel lever only serves as a locking element and has no other function.

Der Erfindung liegt die Aufgabe zugrunde, einen Staubsauger der eingangs beschriebenen Art konstruktiv so auszubilden, daß das Schließen des Deckels bei nicht eingesetztem Filterbeutel mit den ohnehin vorhandenen und benötigten Geräteteilen verhindert ist. Darüber hinaus wird eine einfache Handhabung des Staubsaugers beim Einsetzen des Filterbeutels und Schließen des Deckels angestrebt.The invention has for its object to construct a vacuum cleaner of the type described in such a way that the closure of the lid is prevented when the filter bag is not inserted with the already available and required device parts. In addition, easy handling of the vacuum cleaner when inserting the filter bag and closing the lid is sought.

Die Lösung der gestellten Aufgabe gelingt nach der Erfindung dadurch, daß der Deckel zur Staubsaugervorderseite hin abgewinkelt und mit dem Ende des abgewinkelten Teiles am Staubsaugergehäuse angelenkt ist, daß ferner der Saugstutzen an dem abgewinkelten Teil angeformt und das Halteteil dem Saugstutzen gegenüberliegend an der vorderen Begrenzungswand des Staubraumes angelenkt und rahmenartig ausgebildet ist sowie an den beiden senkrecht zur Schwenkachse verlaufenden Seiten Führungsnuten für die Versteifungsplatte des Filterbeutels aufweist, wobei der Deckel mit seiner Knickstelle beim Schließen bei nicht eingelegtem Filterbeutel auf das Halteteil auftrifft und mit diesem verklemmt, wogegen das Halteteil bei eingelegtem Filterbeutel durch den auf die Versteifungsplatte auftreffenden Saugstutzen in seine Betriebslage verschwenkt wird.The object is achieved according to the invention in that the lid is angled toward the front of the vacuum cleaner and is articulated with the end of the angled part on the vacuum cleaner housing, that the suction nozzle is also formed on the angled part and the holding part is opposite the suction nozzle on the front boundary wall of the Dust space is articulated and frame-like and has guide grooves for the stiffening plate of the filter bag on the two sides perpendicular to the swivel axis, the cover hitting the clamping part with its kink when the filter bag is not inserted and jammed with it, whereas the holding part with the filter bag inserted is pivoted into its operating position by the suction nozzle striking the stiffening plate.

Das für die Halterung des Filterbeutels ohnehin erforderliche Halteteil übernimmt im Zusammenwirken mit dem entsprechend gestalteten Deckel gleichzeitig die Funktion eines Sperrelementes. Der Filterbeutel kann mit seiner Versteifungsplatte mit einer Hand in die Führungsnuten eingeschoben werden, wobei sich das Halteteil in der senkrechten Stellung befindet und damit besonders leicht zugänglich ist. Der Deckel ist am Staubsaugergehäuse angelenkt, so daß das Verschließen des Staubraumes durch bloßes Zurückschwenken des Deckels erfolgt. Dabei gelangt der am Deckel angeformte Saugstutzen selbsttätig in die Einlaßöffnung der Versteifungsplatte und schwenkt außerdem das Halteteil in seine Betriebslage. Bei nicht eingesetztem Filterbeutel stößt der Saugstutzen durch die Rahmenöffnung des Halteteiles, das dann in seiner senkrechten Stellung verbleibt und ein Schließen des Deckels verhindert.The holding part, which is required anyway for holding the filter bag, takes on the function of a blocking element in cooperation with the appropriately designed cover. With its stiffening plate, the filter bag can be inserted into the guide grooves with one hand, the holding part being in the vertical position and thus being particularly easily accessible. The lid is hinged to the vacuum cleaner housing, so that the dust chamber is closed by simply pivoting the lid back. The suction nozzle formed on the lid automatically enters the inlet opening of the stiffening plate and also swivels the holding part into its operating position. When the filter bag is not inserted, the suction nozzle pushes through the frame opening of the holding part, which then remains in its vertical position and prevents the lid from closing.

Dadurch, daß am Außenumfang des Saugstutzens gegenüber dessen Ende mindestens um die Stärke der Versteifungsplatte zurückgesetzte Vorsprünge vorgesehen sind, wird auch bei einer gegenüber dem Außendurchmesser des Saugstutzens zu großen Einlaßöffnung ein Verschwenken des Halteteiles beim Schließen des Deckels erreicht.Characterized in that on the outer periphery of the suction nozzle opposite to the end of at least the thickness of the stiffening plate projections are provided, even when the inlet opening is too large compared to the outer diameter of the holding part is pivoted when closing the lid.

Eine Verbesserung der Sperrwirkung wird noch dadurch erreicht, daß an dem Deckel eine oder mehrere parallel zum Saugstutzen verlaufende Rippen vorgesehen und an dem Halteteil in ihrer Lage zu den Rippen ausgerichtete Sperrnasen angeformt sind. Beim Schließen des Deckels treffen die Rippen auf die Sperrnasen, wenn das Halteteil bei nicht eingelegtem Filterbeutel nicht zurückgeschwenkt wird. Durch dieses Aufeinandertreffen der Rippen und Sperrnasen wird auch bei einer eventuellen leichten Schrägstellung des Halteteiles mit Sicherheit eine Sperrwirkung erreicht.An improvement in the locking effect is achieved in that one or A plurality of ribs running parallel to the suction nozzle are provided and locking lugs are formed on the holding part in their position relative to the ribs. When the lid is closed, the ribs meet the locking lugs if the holding part is not pivoted back when the filter bag is not inserted. Through this meeting of the ribs and locking lugs, a locking effect is achieved with a possible slight inclination of the holding part.

Anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispiels wird der Anmeldungsgegenstand nachfolgend näher beschrieben. Es zeigt

  • Figur 1 einen Staubsauger mit eingelegtem Filterbeutel und geschlossenem Deckel,
  • Figur 2 einen Staubsauger mit eingelegtem Filterbeutel und geöffnetem Deckel,
  • Figur 3 einen Staubsauger ohne eingelegten Filterbeutel und geöffnetem Deckel,
  • Figur 4 einen Staubsauger mit eingelegtem Filterbeutel und geschlossenem Deckel, dessen Saugstutzen am Außenumfang Radialvorsprünge aufweist.
The subject of the application is described in more detail below with reference to an exemplary embodiment shown schematically in the drawing. It shows
  • FIG. 1 shows a vacuum cleaner with an inserted filter bag and closed lid,
  • FIG. 2 shows a vacuum cleaner with an inserted filter bag and open lid,
  • FIG. 3 shows a vacuum cleaner without a filter bag inserted and the lid open,
  • Figure 4 shows a vacuum cleaner with an inserted filter bag and closed lid, the suction nozzle on the outer circumference has radial projections.

Mit 1 ist das Gehäuse eines Staubsaugers bezeichnet, in dem ein einen Filterbeutel aufnehmender Staubraum 3 vorgesehen ist. An dem Gehäuse 1 ist ein den Staubraum verschließender Deckel 4 angelenkt. An dem Deckel 4 ist ferner ein Saugstutzen 5 angeformt, der in eine in der Versteifungsplatte 6 des Filterbeutels 2 vorgesehene Einlaßöffnung 7 hineinragt. An der vorderen Begrenzungswand 8 des Staubraumes 3 ist ein rahmenartig ausgebildetes Halteteil 9 schwenkbar angeordnet. Auf der dem Staubraum zugewandten Seite des Halteteils 9 sind auf beiden Seiten Führungsnuten 10 ausgebildet, in welche die Versteifungsplatte 6 einsteckbar ist. An dem Deckel 4 sind ferner Rippen 11 angeformt, die mit an dem Halteteil 9 angeformten Sperrnasen 12 zusammenwirken.With 1 the housing of a vacuum cleaner is designated, in which a dust bag 3 is provided which holds a filter bag. A lid 4, which closes the dust chamber, is articulated on the housing 1. A suction nozzle 5 is also formed on the cover 4 and projects into an inlet opening 7 provided in the stiffening plate 6 of the filter bag 2. On the front boundary wall 8 of the dust chamber 3, a frame-like holding part 9 is pivotally arranged. On the side of the holding part 9 facing the dust chamber, guide grooves 10 are formed on both sides, into which the stiffening plate 6 can be inserted. Ribs 11 are also formed on the cover 4, which cooperate with locking lugs 12 formed on the holding part 9.

In Fig. ist der Deckel 4 in aufgeklappter Stellung gezeigt. In dieser Stellung wird das Halteteil 9 durch nicht dargestellte Federn in seine senkrechte Lage geschwenkt. In dieser Lage kann die Versteifungsplatte 6 des Filterbeutels 2 ohne Schwierigkeiten in die Nuten 10 des Halteteils 9 eingesteckt oder aus diesen Nuten 10 herausgezogen werden. Ist ein Filterbeutel 2 mit seiner Versteifungsplatte 6 in die Führungsnuten 10 des Halteteils 9 eingesteckt, so stößt der Saugstutzen 5 beim Schließen des Deckels 4 auf die Versteifungsplatte 6 und verschwenkt das Halteteil 9 im Uhrzeigersinn. Damit werden auch die mit dem Halteteil 9 verbundenen Sperrnasen 12 von den Rippen 11 weggeschwenkt, so daß der Deckel 4 ungehindert geschlossen werden kann.In Fig. The lid 4 is shown in the opened position. In this position, the holding part 9 is pivoted into its vertical position by springs, not shown. In this position, the stiffening plate 6 of the filter bag 2 can be easily inserted into the grooves 10 of the holding part 9 or pulled out of these grooves 10. If a filter bag 2 with its stiffening plate 6 is inserted into the guide grooves 10 of the holding part 9, the suction nozzle 5 strikes the stiffening plate 6 when the lid 4 is closed and pivots the holding part 9 clockwise. Thus, the locking lugs 12 connected to the holding part 9 are pivoted away from the ribs 11, so that the cover 4 can be closed unhindered.

Ist dagegen, wie in Fig.3 3 gezeigt, kein Filterbeutel 2 in dem Staubraum 3 eingesetzt, so stößt der Saugstutzen 5 des Deckels 4 ungehindert durch die Rahmenöffnung des Halteteils 9. Das Halteteil 9 verbleibt somit in seiner senkrech-, ten Lage und der Deckel 4 trifft mit seinen Rippen 11 auf die Sperrnasen 12 und kann nicht geschlossen werden.If, on the other hand, as shown in FIG. 3, no filter bag 2 is inserted in the dust chamber 3, the suction nozzle 5 of the cover 4 pushes freely through the frame opening of the holding part 9. The holding part 9 thus remains in its vertical position and Cover 4 meets the locking lugs 12 with its ribs 11 and cannot be closed.

Bei der Darstellung nach Fig. 4 sind an dem Saugstutzen 5 Radialvorsprünge 13 vorgesehen. Diese Radialvorsprünge 13 sind gegenüber dem Ende 14 des Saugstutzens 5 zurückgesetzt. Ist nämlich die Einlaßöffnung 7 in der Versteifungsplatte 6 größer ausgebildet als der Saugstutzen 5, dann kann dieser durch die Einlaßöffnung 7 hindurchtreten, ohne das Halteteil 9 zu verschwenken. In diesem Fall treffen die Radialvorsprünge 13 auf die Versteifungsplatte 6 und nehmen das Halteteil 9 mit.4, radial projections 13 are provided on the suction nozzle. These radial projections 13 are set back from the end 14 of the suction nozzle 5. If the inlet opening 7 in the stiffening plate 6 is larger than the suction nozzle 5, then this can pass through the inlet opening 7 without pivoting the holding part 9. In this case, the radial projections 13 meet the stiffening plate 6 and take the holding part 9 with them.
