Description

Die Erfindung betrifft einen Staubsauger nach dem Oberbegriff des Anspruches 1.The invention relates to a vacuum cleaner according to the preamble of claim 1.

Aus der EP-A-0 044 501 ist ein Staubsauger dieser Art bekannt, wobei das Gehäuseteil über eine Saugleitung an ein Reinigungswerkzeug des Staubsaugers und ein Gebläse angeschlossen ist. Der vom Sauggebläse erzeugte Saugluftstrom strömt zum Sauggebläse, nachdem der vom Reinigungswerkzeug kommende staubhaltige Saugluftstrom das Staubfilter- und -sammelbehältnis durchströmt hat.A vacuum cleaner of this type is known from EP-A-0 044 501, the housing part being connected to a cleaning tool of the vacuum cleaner and a blower via a suction line. The suction air flow generated by the suction fan flows to the suction fan after the dust-containing suction air flow coming from the cleaning tool has flowed through the dust filter and collection container.

In bestimmten Zeitabständen muß das Staubfilter- und -sammelbehältnis geleert oder ausgewechselt werden, wenn das Behältnis beispielsweise ein Einwegbeutel ist.The dust filter and collection container must be emptied or replaced at certain intervals, for example if the container is a disposable bag.

Da das Staubfilter- und -sammelbehältnis bei starkem Schmutzanfall häufig geleert bzw. ausgewechselt werden muß, muß auch der Deckel einfach und schnell und ohne besondere Vorsichtsmaßnahmen geöffnet und wiederverschlossen werden können. Hierzu ist der Deckel gelenkig und unlösbar am Gehäuseteil befestigt, so daß er in Offenstellung am Gehäuseteil verbleibt und nicht von diesem abgenommen und auf einer Ablagefläche abgelegt zu werden braucht. Da der Deckel aber relativ groß und schwer ist, besteht die Gefahr, daß er oder sein Gelenk durch Anstoßen am Deckel oder beim Einsetzen des Behältnisses oder auch durch unsachgemäßes Öffnen beschädigt oder zerstört werden. Dann muß meist der Deckel oder das Gehäuseteil ersetzt werden, was mit einem erheblichen Arbeits- und Zeitaufwand und Kosten verbunden ist.Since the dust filter and collection container has to be emptied or replaced frequently in the event of heavy dirt accumulation, the lid must also be able to be opened and closed again simply and quickly and without special precautionary measures. For this purpose, the lid is articulated and permanently attached to the housing part, so that it remains in the open position on the housing part and does not need to be removed from it and placed on a storage surface. However, since the lid is relatively large and heavy, there is a risk that it or its joint may be damaged or destroyed by bumping against the lid or when inserting the container, or also by improper opening. Then usually the lid or the housing part must be replaced, which is associated with a considerable amount of work and time and costs.

Der Erfindung liegt die Aufgabe zugrunde, einen Staubsauger dieser Art so auszubilden, daß der Deckel und das Gehäuseteil beim Anstoßen am Deckel oder beim unsachgemäßen Öffnen des Deckels nicht beschädigt oder zerstört werden können.The invention has for its object to provide a vacuum cleaner of this type so that the lid and the housing part can not be damaged or destroyed when bumping against the lid or when improperly opening the lid.

Diese Aufgabe wird bei einem Staubsauger der gattungsbildenden Art mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst.This object is achieved in a vacuum cleaner of the generic type with the characterizing features of claim 1.

Infolge der erfindungsgemäßen Ausbildung wird der geöffnete Deckel bei übermäßiger Krafteinwirkung aus seiner Offenstellung in eine Freigabestellung bewegt, wobei er den auf ihn wirkenden Kräften ausweichen kann. Hierbei kann der Deckel so weit über die Offenstellung hinausbewegtwerden, bis er belastungsfrei am Gehäuseteil zur Anlage kommt. Durch das Wegschwenken des . Deckels ist sichergestellt, daß der Deckel oder das Gehäuseteil nicht beschädigt werden können. Da der Deckel auch in der Freigabestellung am Gehäuseteil gehalten ist, kann er durch entgegengesetzte Bewegung einfach und schnell in seine Schließstellung zurückgeführt werden.As a result of the design according to the invention, the open lid is moved from its open position into a release position in the event of excessive force, it being able to avoid the forces acting on it. Here, the cover can be moved beyond the open position until it comes into contact with the housing part without load. By swinging the. Lid ensures that the lid or the housing part cannot be damaged. Since the cover is also held in the release position on the housing part, it can be quickly and easily returned to its closed position by moving it in the opposite direction.

Weitere Merkmale besonderer Ausführungsarten der Erfindung ergeben sich aus den weiteren Ansprüchen, der Beschreibung und den Zeichnungen.Further features of special embodiments of the invention result from the further claims, the description and the drawings.

Die Erfindung wird nachstehend anhand mehrerer in den Zeichnungen dargestellter Ausführungsbeispiele näher beschrieben.The invention is described below with reference to several exemplary embodiments shown in the drawings.

Fig. 1 zeigt einen Teil eines Staubsaugergehäuses 1, in dem ein Motorgehäuse untergebracht ist, das einen von einem (nicht dargestellten) Reinigungswerkzeug des Staubsaugers kommenden Saugluftstrom über eine (nicht dargestellte) Saugleitung einem als Beutel 3 ausgebildeten Staubfilter- und -sammelbehältnis zuführt. Der Beutel 3 liegt in einem mit einem Deckel verschließbaren Aufnahmeraum 4 des Gehäuseteiles 1, aus dem er zum Entleeren oder, wenn er als Einwegbeutel ausgebildet ist, zum Auswechseln leicht entnommen und in den er entsprechend einfach und schnell wieder eingesetzt werden kann. Der Beutel 3 ist mit einer (nicht dargestellten) Staubluftzuführleitung _ verbunden. Der vom Motorgebläse 2 erzeugte Saugluftstrom durchströmt den Beutel 3, wobei der aufgenommene Schmutz und Staub in bestimmten Zeitabständen entfernt werden muß.1 shows a part of a vacuum cleaner housing 1, in which a motor housing is accommodated, which feeds a suction air stream coming from a (not shown) cleaning tool of the vacuum cleaner via a (not shown) suction line to a dust filter and collecting container designed as a bag 3. The bag 3 lies in a receptacle 4 of the housing part 1 which can be closed with a lid, from which it can be easily removed for emptying or, if it is designed as a disposable bag, for replacement and into which it can be reinserted simply and quickly. The bag 3 is connected to a dust air supply line (not shown). The suction air flow generated by the motor fan 2 flows through the bag 3, the dirt and dust that has been absorbed having to be removed at certain time intervals.

Der großflächig ausgebildete Deckel 5 ist über einen Schwenkarm 6 gelenkig und unlösbar mit dem Gehäuseteil 1 verbunden. Der Schwenkarm 6 ist ein zweiarmiger, länglicher, plattenartiger Hebel. Sein einer Hebelarm 7 ist in Längsrichtung teilkreisförmig gekrümmt und mit einem etwa in halber Länge und radial zu ihm verlaufenden Haltesteg 18 um eine Schwenkachse 8 schwenkbar am Gehäuseteil 1 befestigt. Am anderen, etwa gleich langen und gerade ausgebildeten Hebelarm 12 ist der Deckel 5 schwenkbar gelagert. Die zugehörige Schwenkachse 9 liegt unmittelbar benachbart zu einem konkav gekrümmten Randabschnitt 7b (Fig. 2) des Hebelarmes 7. Das freie Ende 7a des Hebelarmes 7 ist durch einen dünnen Federsteg 10 gebildet, de 7 wesentlich dünner ist als der zwischen dem Haltesteg 18 und dem Hebelarm 12 liegende Armabschnitt 10' (Fig. 2) sowie der Hebelarm 12. Die Enden 7a und 12a des Schwenkarmes 6 weisen jeweils ein Rastglied 11 bzw. 13 einer Haltevorrichtung 11, 16 und 13, 14 auf, mit denen der Deckel 5 in seiner Offenstellung gemäß Fig. 2 gegenüber dem Gehäuseteil verriegelt ist.The large cover 5 is articulated and non-detachably connected to the housing part 1 via a swivel arm 6. The swivel arm 6 is a two-armed, elongated, plate-like lever. One of its lever arms 7 is curved in the form of a part circle in the longitudinal direction and is fastened to the housing part 1 by means of a retaining web 18 which extends approximately in half length and runs radially to it about a pivot axis 8. On the other, approximately equally long and straight lever arm 12, the cover 5 is pivotally mounted. The associated pivot axis 9 is immediately adjacent to a concavely curved edge section 7b (FIG. 2) of the lever arm 7. The free end 7a of the lever arm 7 is formed by a thin spring web 10, which is 7 significantly thinner than that between the holding web 18 and the Lever arm 12 lying arm section 10 '(Fig. 2) and the lever arm 12. The ends 7a and 12a of the swivel arm 6 each have a locking member 11 or 13 of a holding device 11, 16 and 13, 14 with which the cover 5 in its 2 is locked against the housing part.

In der Offenstellung liegt das nockenförmige Rastglied 11 des Hebelarmes 7 in einem nutförmig ausgebildeten Rastgegenglied 16 einer Gehäusewand 17, während das schulterförmig ausgebildete Rastglied 13 des Hebelarmes 12 an einem bügelartigen Rastgegenglied 14 des Deckels 5 anliegt. Gleichzeitig stützt sich der Schwenkarm 6 mit einem Vorsprung 20 an einer Innenfläche 15 des Deckels 5 ab, wodurch der Deckel beim Öffnen auf die Haltevorrichtung 13, 14 eine Gegenkraft ausübt, so daß die Rastvorrichtung in Schließstellung und während des Öffnens nicht unbeabsichtigt gelöst wird.In the open position, the cam-shaped locking member 11 of the lever arm 7 lies in a groove-shaped locking counter-member 16 of a housing wall 17, while the shoulder-shaped locking member 13 of the lever arm 12 bears against a bow-like locking counter-member 14 of the cover 5. At the same time, the swivel arm 6 is supported with a projection 20 on an inner surface 15 of the lid 5, whereby the lid exerts a counterforce when opening the holding device 13, 14, so that the latching device is not unintentionally released in the closed position and during opening.

Wenn der Deckel 5 zum Öffnen in Richtung des Pfeiles Pin Fig. 2 geschwenkt wird, schwenkt auch der über die Haltevorrichtung 13, 14 fest mit dem Deckel 5 verbundene Schwenkarm 6 um seine Schwenkachse 8 am Gehäuseteil 1, bis das Rastglied 11 am Ende 7a des Hebelarmes 7 in das Rastgegenglied 16 der Gehäusewand 17 einrastet. Hierbei kommt der Haltesteg 18 an einem Anschlag 19 des Gehäuseteiles 1 zur Anlage, so daß der Schwenkarm nicht über die Offenstellung hinaus verschwenkt werden kann. Der Deckel 5 befindet sich nun in einer annähernd senkrechten Stellung zum Gehäuseteil 1 und damit in seiner gebrauchsmäßigen Offenstellung, in der der Beutel 3 aus dem Aufnahmeraum 4 herausgenommen und anschließend wieder in diesen eingesetzt werden kann (Fig. 2).If the cover 5 is pivoted to open in the direction of the arrow Pin Fig. 2, the pivot arm 6, which is firmly connected to the cover 5 via the holding device 13, 14, pivots about its pivot axis 8 on the housing part 1 until the latching member 11 at the end 7a of the Lever arm 7 engages in the locking counter member 16 of the housing wall 17. Here, the holding web 18 comes to rest against a stop 19 of the housing part 1, so that the swivel arm cannot be pivoted beyond the open position. The lid 5 is now in an approximately vertical position to the housing part 1 and thus in its open position in use, in which the bag 3 can be removed from the receiving space 4 and then reinserted into it (FIG. 2).

Beim Öffnen des Deckels 5 dient der vom Haltesteg abgewandte, ununterbrochene, konvex gekrümmte Randabschnitt 7c des Hebelarmes 7 als Führungsteil, mit dem der Schwenkarm 6 längs eines freien Endes 17a (Fig. 1) der Gehäusewand 17 gleitet. Dadurch ist der Deckel beim Verschwenken genau gegenüber dem Gehäuseteil 1 ausgerichtet, so daß er leichtgängig verschwenkt werden kann und eine Beschädigung der Gelenkteile einwandfrei verhindert ist.When opening the cover 5, the uninterrupted, convexly curved edge section 7c of the lever arm 7 facing away from the holding web serves as a guide part with which the swivel arm 6 slides along a free end 17a (FIG. 1) of the housing wall 17. As a result, the cover is aligned exactly with respect to the housing part 1 when pivoting, so that it can be pivoted smoothly and damage to the joint parts is properly prevented.

Wirken auf den Deckel 5 in seiner Offenstellung nach Fig. 2, z.B. durch Anstoßen am Deckel beim Herausnehmen oder Wiedereinsetzen des Beutels 3 oder auch beim Öffnen durch unsachgemäße Bedienung übermäßige Kräfte, dann wird der Deckel 5 über die Offenstellung hinaus in eine Freigabestellung (Fig. 3) geschwenkt. Dabei wird das Rastgegenglied 14 über das Rastglied 13 hinweg gedrückt, so daß die Haltevorrichtung 13, 14 gelöst ist und der Deckel in Richtung des Pfeiles P den auf ihn wirkenden Kräften ausweichen kann. Gleichzeitig bleibt aber die Rastverbindung der Haltevorrichtung 11,16 bestehen, da der Anschlag 19 des Gehäuseteiles 1 verhindert, daß sich der Schwenkarm 6 mitdrehen kann. Infolge dieser Ausweichbewegung des Deckels 5 ist sichergestellt, daß die Krafteinwirkung auf den Deckel und damit das Gehäuseteil nicht zu einer Beschädigung oder Zerstörung dieser Teile führen kann.Act on the lid 5 in its open position according to Fig. 2, e.g. by bumping the lid when removing or reinserting the bag 3 or when opening it due to improper operation, excessive forces are applied, then the lid 5 is pivoted beyond the open position into a release position (FIG. 3). The locking counter-member 14 is pressed over the locking member 13 so that the holding device 13, 14 is released and the cover in the direction of arrow P can avoid the forces acting on it. At the same time, however, the latching connection of the holding device 11, 16 remains, since the stop 19 of the housing part 1 prevents the swivel arm 6 from rotating. As a result of this evasive movement of the cover 5, it is ensured that the force acting on the cover and thus the housing part cannot lead to damage or destruction of these parts.

Aus der Freigabestellung kann der Deckel 5 in die Schließstellung (Fig. 1) einfach und schnell durch Verschwenken entgegen der Richtung des Pfeiles P gebracht werden. Dabei wird selbsttätig die Rastverbindung der Haltevorrichtung 13, 14 wieder hergestellt und die Rastverbindung der Haltevorrichtung 11, 16 gelöst, so daß der Deckel nach dem Schließen ohne zusätzliche Maßnahmen erneut geöffnet werden kann.From the release position, the cover 5 can be brought into the closed position (FIG. 1) simply and quickly by pivoting against the direction of the arrow P. The locking connection of the holding device 13, 14 is automatically restored and the locking connection of the holding device 11, 16 is released, so that the lid can be opened again after closing without additional measures.

Der die höchstzulässige Offenstellung begrenzende Anschlag kann z.B. als Kapsel 50 (Fig. 4, 5) ausgebildet sein, die die Windungen der Schenkelfelder45 koaxial übergreift. Ein Teil der Kapselwand ist entfernt, so daß zwei Anschlagkanten 51 und 52 entstehen, an welchem die Schenkel 46 und 47 der Schenkelfeder 45 unter Einschließung des höchstzulässigen Öffnungswinkels a anliegen.The stop limiting the maximum permissible open position can e.g. be designed as a capsule 50 (FIGS. 4, 5) which coaxially engages over the turns of the leg fields 45. Part of the capsule wall is removed, so that two stop edges 51 and 52 are formed, on which the legs 46 and 47 of the leg spring 45 lie, including the maximum permissible opening angle a.

Bei einer weiteren Möglichkeit (Fig. 6, 7) einer Begrenzung des höchstzulässigen Öffnungswinkels a ist der Anschlag als Lasche 53 ausgebildet, welche mit Öffnungen 54, 54' versehen ist, in die die Schenkel 46 und 47 der Schenkelfeder 45 ragen. Der höchstzulässige Öffnungswinkel a der beiden Schenkel 46 und 47 wird durch Anliegen dieser Schenkel an den sich auf größtem Abstand zueinander befindenden Wänden der Öffnungen 54, 54' gebildet.In a further possibility (FIGS. 6, 7) of limiting the maximum permissible opening angle a, the stop is designed as a tab 53 which is provided with openings 54, 54 'into which the legs 46 and 47 of the leg spring 45 protrude. The maximum permissible opening angle α of the two legs 46 and 47 is formed by the abutment of these legs on the walls of the openings 54, 54 'which are at the greatest distance from one another.

Eine weitere Möglichkeit besteht darin, die Vorspannung der Schenkelfeder 45 so zu wählen, daß der Offnungswinkel der beiden Schenkel 46 und 47 in entspanntem Zustand der Schenkelfeder 45 geringer ist als der höchstzulässige Öffnungswinkel a.Another possibility is to choose the pretension of the leg spring 45 so that the opening angle of the two legs 46 and 47 in the relaxed state of the leg spring 45 is less than the maximum permissible opening angle a.

Zur weiteren Öffnung des Deckelteiles 5 ist es dann erforderlich, den Deckel 5 von Hand weiterzubewegen. Um eine Deformierung der Schenkelfeder 45 zu vermeiden, ist es angebracht, den höchstzulässigen Öffnungswinkel a durch z.B. die vorgenannten Anschlagelemente 50 bzw. 53 zu begrenzen. Der maximale Öffnungswinkel a ist kleiner als 180°.To open the cover part 5 further, it is then necessary to move the cover 5 further by hand. In order to avoid deformation of the leg spring 45, it is appropriate to adjust the maximum permissible opening angle a by e.g. limit the abovementioned stop elements 50 and 53. The maximum opening angle a is less than 180 °.
