Description

Die Erfindung betrifft ein Staubsaugermundstück mit einem verschwenkbaren Anschlußstutzen und einem Mund­stückkörper, der an einem gelenkig mit dem Anschluß­stutzen verbundenen Zwischenkanal kippbar gelagert ist, bei welchem Mundstück ferner mit dem Anschlußstutzen ein auf der abzusaugenden Fläche aufliegendes Abstütz­element verbunden ist.The invention relates to a vacuum cleaner mouthpiece with a pivotable connecting piece and a mouthpiece body which is tiltably mounted on an intermediate channel articulated to the connecting piece, in which mouthpiece a supporting element resting on the surface to be suctioned is further connected to the connecting piece.

Ein solches Staubsaugermundstück ist durch die DE-PS 28 46 847 bekannt. Wegen der verschwenkbaren Auf­hängung an dem Zwischenkanal kann sich der Mundstück­körper so einstellen, daß seine Mundstücksohle möglichst parallel zur abzusaugenden Fläche gerichtet ist. Dies ist jedoch nur dann der Fall, wenn die beim Hin- und Herbewegen an der Mundstücksohle wirksam werdenden Rei­bungskräfte klein sind. Ansonsten wird der Mundstück­körper infolge dieser Reibungskräfte um seine Aufhänge­achse gekippt. Dies tritt vor allem beim Bewegen des Mundstückes in rückwärtiger Richtung auf und führt zu dem sogenannten "Rattern" des Mundstückes.Such a vacuum cleaner mouthpiece is known from DE-PS 28 46 847. Because of the pivotable suspension on the intermediate channel, the mouthpiece body can adjust itself so that its mouthpiece sole is directed as parallel as possible to the surface to be extracted. However, this is only the case if the frictional forces which become effective during the back and forth movement on the mouthpiece sole are small. Otherwise, the mouthpiece body is tilted around its suspension axis due to these frictional forces. This occurs especially when moving the mouthpiece in the backward direction and leads to the so-called "rattling" of the mouthpiece.

Der Erfindung liegt die Aufgabe zugrunde, ein Staub­saugermundstück der eingangs beschriebenen Art so weiterzubilden, daß ein Kippen des Mundstückkörpers in beiden Bewegungsrichtungen sicher verhindert wird und somit die Mundstücksohle immer voll auf der abzu­saugenden Fläche aufliegt.The invention has for its object to develop a vacuum cleaner mouthpiece of the type described in such a way that tilting of the mouthpiece body is reliably prevented in both directions of movement and thus the mouthpiece sole always lies fully on the surface to be extracted.

Die Lösung der gestellten Aufgabe gelingt nach der Erfin­dung dadurch, daß an der in Bezug auf die Arbeitsrich­tung des Staubsaugermundstückes hinteren Längsseite des Mundstückkörpers ein Koppelelement mit seinem einen Ende angelenkt ist, das mit seinem anderen Ende gelenkig mit dem Anschlußstutzen verbunden ist, daß ferner der Zwischenkanal aus zwei in Richtung der Längsachse des Zwischenkanals durch eine Gelenkstelle voneinander ent­koppelten Teilkanälen besteht. Durch die Aufteilung des Zwischenkanals in zwei in Längsrichtung des Zwischen­kanals voneinander entkoppelte Teilkanäle kann über den Zwischenkanal keine horizontale Kraft auf den Mundstück­körper übertragen werden. Die beim Hin- und Herbewegen des Mundstückes wirkenden Horizontalkräfte werden über das Koppelelement auf den Mundstückkörper übertragen. Dabei ist es besonders vorteilhaft, daß das Koppelele­ment an einer möglichst tiefliegenden Stelle am Mund­stückkörper angelenkt ist. Hierdurch ergibt sich ein äußerst kleiner Hebelarm zwischen der an der Mundstück­sohle wirksamen Reibungskraft und der horizontalen Schiebekraft, sodaß das auf den Mundstückkörper wirken­de Kippmoment entsprechend stark reduziert ist.The object is achieved according to the invention in that on the rear longitudinal side of the mouthpiece body in relation to the working direction of the vacuum cleaner mouth, a coupling element is articulated at one end, which is articulated at its other end to the connecting piece, that the intermediate channel consists of two sub-channels decoupled from one another in the direction of the longitudinal axis of the intermediate channel by an articulation point. Due to the division of the intermediate channel into two subchannels decoupled from one another in the longitudinal direction of the intermediate channel, no horizontal force can be transmitted to the mouthpiece body via the intermediate channel. The horizontal forces acting when the mouthpiece is moved back and forth are transmitted to the mouthpiece body via the coupling element. It is particularly advantageous that the coupling element is articulated at the lowest possible point on the mouthpiece body. This results in an extremely small lever arm between the frictional force acting on the mouthpiece sole and the horizontal pushing force, so that the tilting moment acting on the mouthpiece body is correspondingly greatly reduced.

Dadurch, daß das Koppelelement als Tragplatte ausgebil­det ist, kann ein gesondertes Abstützelement für das Mundstück eingespart werden. Fertigungstechnische Vor­teile ergeben sich daraus, daß die Tragplatte einteilig mit dem Gehäuse des Mundstückkörpers ausgebildet und einerseits über ein Filmscharnier an dem der abzusau­genden Fläche benachbarten Rand der hinteren Längs­seite des Gehäuses sowie andererseits mittels ange­formter Laschen an dem Anschlußstutzen angelenkt ist. Die Tragplatte kann somit in einem Herstellungsvorgang zusammen mit dem Gehäuse des Mundstückkörpers herge­stellt werden. Darüberhinaus entfällt ein gesonderter Montagevorgang für das Anlenken der Tragplatte an dem Mundstückkörper.Because the coupling element is designed as a support plate, a separate supporting element for the mouthpiece can be saved. Manufacturing advantages result from the fact that the support plate is formed in one piece with the housing of the mouthpiece body and is articulated on the one hand via a film hinge on the edge of the rear longitudinal side of the housing adjacent to the surface to be suctioned off and on the other hand by means of integrally formed tabs on the connecting piece. The support plate can thus be produced in one manufacturing process together with the housing of the mouthpiece body. In addition, there is no separate one Assembly process for the articulation of the support plate on the mouthpiece body.

Bei einem Staubsaugermundstück, das an dem Anschluß­stutzen ein Räderpaar aufweist, kann die Tragplatte mit ihren angeformten Laschen auf der Achse des Räder­paares gelagert werden. Für die Räder sind Durchtritts­schlitze an der Tragplatte ausgebildet, so daß die Räder über die Auflageebene der Tragplatte vorstehen können. Dies hat besondere Vorteile, wenn mit dem Mundstück glatte Böden gesaugt werden, da dann das Mundstück von dem Räderpaar abgestützt und dadurch eine Berührung der Tragplatte mit dem glatten Boden vermieden wird.In the case of a vacuum cleaner mouthpiece which has a pair of wheels on the connecting piece, the support plate with its integrally formed tabs can be mounted on the axle of the pair of wheels. Passage slots are formed on the support plate for the wheels so that the wheels can protrude beyond the support plane of the support plate. This has particular advantages if smooth bottoms are sucked with the mouthpiece, since then the mouthpiece is supported by the pair of wheels and contact between the support plate and the smooth bottom is avoided.

Anhand eines in der Zeichnung dargestellten Ausführungs­beispieles wird der Anmeldungsgegenstand nachfolgend näher beschrieben. Es zeigt:

  • Fig. 1 eine Seitenansicht eines Staubsaugermundstückes nach der Erfindung,
  • Fig. 2 das Staubsaugermundstück nach Fig. 1 im Schnitt,
  • Fig. 3 in einem Teilschnitt den aus zwei Teilkanälen bestehenden Zwischenkanal.
The subject of the application is described in more detail below using an exemplary embodiment shown in the drawing. It shows:
  • 1 is a side view of a vacuum cleaner mouthpiece according to the invention,
  • 2 the vacuum cleaner mouthpiece according to FIG. 1 in section,
  • Fig. 3 in a partial section, the intermediate channel consisting of two sub-channels.

Ein mit 1 bezeichnetes Staubsaugermundstück weist einen Mundstückkörper 2 und einen Anschlußstutzen 3 auf. Über einen aus einem ersten und zweiten Teilkanal 4a und 4b bestehenden Zwischenkanal 4 ist der Mundstückkörper 2 mit dem Anschußstutzen 3 mechanisch und saugmäßig ver­bunden. Der Mundstückkörper 2 ist mittels einer Schwenk­achse 5 an dem ersten Teilkanal 4a verschwenkbar befe­stigt. Mit dem zweiten Teilkanal 4b ist der Anschluß­stutzen 3 verschwenkbar verbunden. Die beiden Teilkanäle 4a und 4b sind in Längsrichtung kräftemäßig voneinander entkoppelt. Bei dem dargestellten Ausführungsbeispiel ist diese Entkopplung dadurch erreicht, daß der erste Teilkanal 4a mit einem der Öffnung 6 des zweiten Teil­kanals 4b angepaßten Rohransatz 7 in die Öffnung 6 des zweiten Teilkanals 4b eingesteckt ist. Der Außendurch­messer des Rohransatzes 7 ist kleiner gewählt als der Innendurchmesser der Öffnung 6 des zweiten Teilkanals 4b, sodaß die beiden Teilkanäle 4a und 4b in Längsrich­tung gegeneinander bewegbar sind. Der Rohransatz 7 ist mit Dichtlippen 8 versehen, durch die ein Ansaugen von Nebenluft über den zwischen dem Rohransatz 7 und der Öffnung 6 bestehenden Ringspalt 9 verhindert wird. Es sind auch andere Arten der Abdichtung möglich, so kann beispielsweise innerhalb des Ringspaltes 9 ein Dichtring auf dem Rohransatz 7 angeordnet werden.A vacuum cleaner mouthpiece designated 1 has a mouthpiece body 2 and a connecting piece 3. The mouthpiece body 2 is mechanically and suction-connected to the connecting piece 3 via an intermediate channel 4 consisting of a first and second subchannel 4a and 4b. The mouthpiece body 2 is pivotally attached to the first subchannel 4a by means of a pivot axis 5. With the second sub-channel 4b, the connecting piece 3 is pivotally connected. The two sub-channels 4a and 4b are in the longitudinal direction of their strength decoupled. In the exemplary embodiment shown, this decoupling is achieved in that the first subchannel 4a is inserted into the opening 6 of the second subchannel 4b with a tube extension 7 adapted to the opening 6 of the second subchannel 4b. The outer diameter of the tube extension 7 is selected to be smaller than the inner diameter of the opening 6 of the second sub-channel 4b, so that the two sub-channels 4a and 4b can be moved relative to one another in the longitudinal direction. The tube extension 7 is provided with sealing lips 8, by means of which secondary air is prevented from being sucked in via the annular gap 9 existing between the tube extension 7 and the opening 6. Other types of sealing are also possible, for example a sealing ring can be arranged on the tubular extension 7 within the annular gap 9.

Als Abstützelement für das Staubsaugermundstück 1 ist auf einer mit dem Anschlußstutzen 3 verbundenen Achse 10 ein Räderpaar 11 vorgesehen. Auf der Achse 10 des Räderpaares 11 ist zusätzlich eine Tragplatte 12 mittels an ihr angeformten Laschen 13 verschwenkbar gelagert. Die Tragplatte 12 ist ferner über ein Filmscharnier 14 an der in Bezug auf die Arbeitsrichtung des Staubsauger­mundstückes 1 hinteren Längsseite des Gehäuses 15 des Mundstückkörpers 2 angelenkt. Die Tragplatte 12 bildet somit das Koppelelement zwischen dem Mundstückkörper 2 und dem Anschußstutzen 3. Die Tragplatte 12 wird zweck­mäßigerweise in einem Arbeitsgang zusammen mit dem Gehäuse 15 des Mundstückkörpers 2 hergestellt, wobei gleichzeitig das Filmscharnier 14 ausgebildet wird.A pair of wheels 11 is provided as a supporting element for the vacuum cleaner mouthpiece 1 on an axle 10 connected to the connecting piece 3. On the axle 10 of the pair of wheels 11, a support plate 12 is additionally pivotally mounted by means of tabs 13 formed thereon. The support plate 12 is also articulated via a film hinge 14 on the rear longitudinal side of the housing 15 of the mouthpiece body 2 with respect to the working direction of the vacuum cleaner mouthpiece 1. The support plate 12 thus forms the coupling element between the mouthpiece body 2 and the connecting piece 3. The support plate 12 is expediently produced in one operation together with the housing 15 of the mouthpiece body 2, the film hinge 14 being formed at the same time.

Durch die Entkopplung der beiden Teilkanäle 4a und 4b in Längsrichtung können über den Zwischenkanal 4 keine Horizontalkräfte auf den Mundstückkörper 2 übertragen werden. Die beim Hin- und Herbewegen des Staubsauger­mundstückes 1 wirksam werdenden Horizontalkräfte werden vielmehr über die Tragplatte 12 auf den Mundstückkörper 2 übertragen. Da die Tragplatte 12 über das Filmschar­nier 14 an dem unteren, der abzusaugenden Fläche benach­barten Rand des Gehäuses 15 angelenkt ist, besteht zwischen den Angriffspunkten der Reibungskraft und der Horizontalkraft nur ein kleiner senkrechter Abstand, sodaß das durch diese Kräfte hervorgerufene und auf den Mundstückkörper 2 wirkende Kippmoment entsprechend klein ist. Es ist daher wichtig, die Anlenkverbindung der Tragplatte 12 an dem Mundstückkörper 2 so tief als möglich vorzusehen. Infolge des nur noch kleinen Kipp­momentes neigt der Mundstückkörper 2 beim Rückwärtsbe­wegen nicht mehr zum Rattern und es ist bei der Vor­wärtsbewegung des Mundstückes eine einwandfreie und vollständige Auflage des Mundstückkörpers 2 auf der abzusaugenden Fläche gewährleistet.By decoupling the two subchannels 4a and 4b in the longitudinal direction, no horizontal forces can be transmitted to the mouthpiece body 2 via the intermediate channel 4 will. The horizontal forces which become effective when the vacuum cleaner mouthpiece 1 is moved back and forth are rather transmitted to the mouthpiece body 2 via the support plate 12. Since the support plate 12 is articulated via the film hinge 14 to the lower edge of the housing 15 adjacent to the surface to be extracted, there is only a small vertical distance between the points of application of the frictional force and the horizontal force, so that the force caused by these forces and acting on the mouthpiece body 2 Tilting moment is correspondingly small. It is therefore important to provide the articulation of the support plate 12 on the mouthpiece body 2 as deep as possible. As a result of the only small tilting moment, the mouthpiece body 2 no longer tends to rattle when it is moved backwards, and a perfect and complete support of the mouthpiece body 2 on the surface to be suctioned off is ensured during the forward movement of the mouthpiece.

Beim dargestellten Ausführungsbeispiel ist zur Abstüt­zung des Mundstückes ein Räderpaar 11 vorgesehen. Auf ein solches Räderpaar 11 kann gegebenenfalls verzichtet werden und die Abstützung des Mundstückes allein über die Tragplatte 12 erfolgen.In the illustrated embodiment, a pair of wheels 11 is provided to support the mouthpiece. Such a pair of wheels 11 can optionally be dispensed with and the mouthpiece is supported solely via the support plate 12.

Die Darstellung in Fig. 3 zeigt eine weitere Möglichkeit der Entkoppelung der beiden Teilkanäle 4a und 4b. Die voreinanderliegenden Enden 16 und 17 der beiden Teil­kanäle sind über ein elastisches Verbindungsteil 18, zum Beispiel einen Faltenbalg miteinander verbunden. Ein solches Verbindungsteil 18 gewährleistet einerseits un­abhängige Bewegungen der beiden Teilkanäle 4a und 4b gegeneinander und übernimmt andererseits gleichzeitig die notwendigen Dichtfunktionen.The illustration in FIG. 3 shows a further possibility of decoupling the two subchannels 4a and 4b. The ends 16 and 17 of the two sub-channels lying in front of one another are connected to one another via an elastic connecting part 18, for example a bellows. Such a connecting part 18 ensures, on the one hand, independent movements of the two subchannels 4a and 4b against one another and, on the other hand, takes over the necessary sealing functions at the same time.

Der Verschiebeweg zwischen den beiden Teilkanälen 4a und 4b wird durch einen an dem Übergang zwischen dem ersten Teilkanal 4a und dem Rohransatz 7 vorgesehenen Anschlagrand 19 begrenzt, der bei einer entsprechenden Verschiebebewegung der beiden Teilkanäle 4a und 4b auf den Rand 20 der Öffnung 6 trifft.The displacement path between the two subchannels 4a and 4b is limited by a stop edge 19 provided at the transition between the first subchannel 4a and the pipe extension 7, which meets the edge 20 of the opening 6 when the two subchannels 4a and 4b are moved accordingly.

Desgleichen wird die Verschwenkbewegung des Mundstück­körpers 2 durch eine an dem zweiten Teilkanal 4b ange­formte erste Anschlagnase 21 begrenzt. Eine ebenfalls an dem zweiten Teilkanal 4b angeformte zweite Anschlag­nase 22 begrenzt die Verschwenkbewegung zwischen dem Anschlußstutzen 3 und dem zweiten Teilkanal 4b und er­möglicht das Abheben des Mundstückkörpers 2 von der ab­zusaugenden Fläche. Hierzu muß der Anschlußstutzen 3 über ein angeschlossenes Saugrohr entsprechend weit im Uhrzeigersinn verschwenkt werden. Sobald die auf der Innenseite des Anschlußstutzens 3 vorgesehene Anschlag­fläche 23 auf die zweite Anschlagnase 22 trifft, wird der zweite Teilkanal 4b nach oben mitgenommen und da­durch der Mundstückkörper 2 vom Boden abgehoben. Die erste Anschlagnase 21 legt sich dabei an der Wand des Gehäuses 15 an.Likewise, the pivoting movement of the mouthpiece body 2 is limited by a first stop lug 21 formed on the second subchannel 4b. A second stop lug 22, which is also formed on the second subchannel 4b, limits the pivoting movement between the connecting piece 3 and the second subchannel 4b and enables the mouthpiece body 2 to be lifted off the surface to be suctioned off. For this purpose, the connecting piece 3 must be pivoted far clockwise via a connected suction pipe. As soon as the abutment surface 23 provided on the inside of the connection piece 3 meets the second abutment nose 22, the second sub-channel 4b is carried upwards and the mouthpiece body 2 is thereby lifted off the floor. The first stop lug 21 lies against the wall of the housing 15.
