Description

Die Erfindung betrifft ein Saugmundstuck gemäß dem Oberbegriff des ersten Anspruchs.The invention relates to a suction mouthpiece according to the preamble of the first claim.

Ein bekanntes Saugmundstück dieser Art (DE-OS 28 46 847)weist einen Düsenkörper auf, der über ein daran gelenkig angesetztes Absaugrohrstück über ein weiteres schwenkbares Rohrgelenk mit einem Absaugstutzen für den Anschluß an einen Staubsauger ausgestattet ist. Der Absaugstutzen ist dabei zusätzlich mit einem um die Rohrlängsachse drehbaren Rohrgelenk versehen. Der an das Absaugrohrstück angekoppelte Absaugstutzenteil ist mit auf gegenüberliegenden Seiten angeordneten Laufrädern versehen, die in der Hauptschieberichtung hinter dem Düsenkörper auf der abzusaugenden Fußbodenfläche abrollen.A known suction mouthpiece of this type (DE-OS 28 46 847) has a nozzle body, which is equipped with a suction pipe piece articulated thereon via a further pivotable pipe joint with a suction nozzle for connection to a vacuum cleaner. The suction nozzle is additionally provided with a pipe joint that can be rotated about the pipe longitudinal axis. The suction nozzle part coupled to the suction pipe piece is provided with impellers which are arranged on opposite sides and roll in the main sliding direction behind the nozzle body on the floor surface to be extracted.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Saugmundstück gemäß dem Oberbegriff des ersten Anspruchs Maßnahmen zu treffen, durch welche ein geschlossener Aufbau erreicht wird.The invention has for its object to take a suction mouthpiece according to the preamble of the first claim measures by which a closed structure is achieved.

Die Lösung dieser Aufgabe erfolgt gemäß der Erfindung durch die kennzeichnenden Merkmale des ersten Anspruchs.This object is achieved according to the invention by the characterizing features of the first claim.

Bei einer Ausgestaltung eines Saugmundstücks gemäß der Erfindung werden die dem Absaugrohrstück zugeordneten Rohrgelenke durch eine auf dieses Absaugrohrstück aufgesteckte Abdeckkappe geschützt, die gleichzeitig auch die seitlich überstehenden Laufräder übergreift. Die Abdeckkappe bildet dabei einen Schutz für die an den Rohrgelenken notwendigen Dichtungslippen, wobei insbesondere der Düsenkörper im Bereich des dort vorgesehenen Rohrgelenks so niedrig ausgebildet werden kann, daß die Dichtungslippe in den Bereich verlegt werden kann, in dem sonst die Gefahr des Anstoßens an Möbelkanten oder dgl. gegeben ist. Die Abdeckung der Räder bewirkt dabei, daß insbesondere beim Saugen unter Polstermöbeln mit Fransen oder Stoffborden die Gefahr vermindert wird, daß sich diese Dekorationselemente im Spalt zwischen den Rädern verfangen. Die Abdeckkappe weist zu ihrer Halterung in Richtung der Schwenkachse an gegenüberliegenden Seitenrändern vorzugsweise Seitenwangen auf, die senkrecht zur Schwenkachse des Rohrgelenks stehen und Rastmittel tragen, welche mit Gegenrasten am Absaugrohrstück lösbar in Eingriff stehen. Das Absaugrohrstück kann hierzu angepaßte senkrecht nach oben gerichtete Wandungsteile aufweisen, welche die Gegenrasten tragen. Die Oberseite der Abdeckkappe ist dabei vorzugsweise rechteckförmig und mit einer solchen Breite ausgebildet, daß sie die äußeren Stirnflächen der Laufräder übergreift und mit den Seitenwangen vor die Stirnflächen der Laufräder greift.In one embodiment of a suction mouthpiece according to the invention, the pipe joints assigned to the suction pipe piece are protected by a cover cap which is fitted onto this suction pipe piece and which at the same time also overlaps the laterally projecting impellers. The cover cap forms a protection for the sealing lips necessary on the pipe joints, in particular the nozzle body in the area of the pipe joint provided there can be made so low that the sealing lip can be moved to the area in which there is otherwise the risk of bumping against furniture edges or Like. Is given. The covering of the wheels has the effect that, especially when vacuuming under upholstered furniture with fringes or fabric shelves, the risk is reduced that these decorative elements get caught in the gap between the wheels. The cover cap has to hold it in the direction of the pivot axis on opposite side edges, preferably side cheeks which are perpendicular to the pivot axis of the pipe joint and carry latching means which are releasably engaged with counter-catches on the suction pipe piece. For this purpose, the suction pipe section can have adapted wall parts which are oriented vertically upward and which bear the counter-catches. The top of the cap is preferably rectangular and of such a width that it overlaps the outer end faces of the impellers and engages with the side cheeks in front of the end faces of the impellers.

Die Erfindung ist anhand eines unmaßstäblich dargestellten Ausführungsbeispiels näher erläutert.The invention is explained in more detail using an exemplary embodiment that is not shown to scale.

Es zeigen:

  • Fig. 1 ein komplettes Saugmundstück in perspektivischer Ansicht,
  • Fig. 2 das Saugmundstück mit angehobener Abdeckkappe und
  • Fig. 3 einen prinzipiellen Querschnitt durch das Saugmundstück.
Show it:
  • 1 is a complete suction mouthpiece in a perspective view,
  • Fig. 2, the suction mouthpiece with a raised cap and
  • Fig. 3 shows a basic cross section through the suction nozzle.

Ein Saugmundstück für einen Staubsauger weist einen Düsenkörper 1 auf, der mit einer Mundstückplatte 2 über eine abzusaugende Bodenfläche 3 zu führen ist. In der Bodenplatte 2 ist ein nach oben gerichteter, quer zur Hauptverschieberichtung verlaufender Saugkanal 4 vorgesehen, der in der Mitte seiner Längserstreckung in einen im wesentlichen nach oben gerichteten Kanalstutzen 5 übergeht. In den Kanalstutzen 5 greift seitlich von oben ein Absaugrohrstück 6 gelenkig ein, wobei es dort um eine Schwenkachse 7 schwenkbar gelagert ist und nach Art eines Rohrschwenkgelenks in den Kanalstutzen eingreift. Zur Abdichtung ist dabei das in den Kanalstutzen eintauchende freie Ende des Absaugrohrstücks 6 als Dichtlippe 8 ausgebildet, die insbesondere an der parallel zur Schwenkachse 7 verlaufenden, zur Oberseite des Düsenkörpers 1 benachbarten Kante ausgebildet ist. Das andere Ende des Absaugrohrstücks 6 ragt entgegen der Hauptfahrrichtung über den Düsenkörper 1 nach hinten hinaus und geht dort in ein weiteres Rohrschwenkgelenk 9 über, das um seine zugeordnete Drehachse 10 ebenfalls begrenzt schwenkbar ist.A suction mouthpiece for a vacuum cleaner has a nozzle body 1 which is to be guided with a mouthpiece plate 2 over a bottom surface 3 to be suctioned off. Provided in the base plate 2 is an upwardly directed suction channel 4 which runs transversely to the main direction of displacement and which in the middle of its longitudinal extent merges into an essentially upwardly directed channel socket 5. A suction pipe piece 6 engages laterally from above in the channel connection piece 5, where it is pivotably mounted about a pivot axis 7 and engages in the channel connection piece in the manner of a pipe swivel joint. For sealing purposes, the free end of the suction tube piece 6, which dips into the duct connection, is designed as a sealing lip 8, which is formed in particular on the edge which runs parallel to the pivot axis 7 and is adjacent to the upper side of the nozzle body 1. The other end of the suction pipe section 6 protrudes rearward beyond the main direction of travel beyond the nozzle body 1 and merges there into a further pipe swivel joint 9, which can also be pivoted to a limited extent about its assigned axis of rotation 10.

Die Schwenkachsen 7 und 10 verlaufen parallel zueinander. Der über das Rohrschwenkgelenk 9 an das Absaugrohrstück 6 angekoppelte Absaugstutzen 11 ist beidseitig mit Laufrädern 12 versehen, welche achsengleich zum Rohrschwenkgelenk 9 gelagert sind und auf der zu reinigenden Bodenfläche 3 frei abrollen. Die Laufräder 12 nehmen dabei Kräfte auf, welche von einem ein an den Absaugstutzen 11 anzusteckenden, von Hand zu führenden Saugrohr oder einem daran anzusteckenden Staubsauger ausgeübt werden. Diese Kräfte wirken sich durch die Zwischenschaltung des Rohrschwenkgelenks 9 praktisch nicht auf den Düsenkörper 1 aus.The pivot axes 7 and 10 run parallel to each other. The suction nozzle 11, which is coupled to the suction pipe piece 6 via the pipe swivel joint 9, is provided on both sides with impellers 12 which are mounted in the same axis as the pipe swivel joint 9 and roll freely on the floor surface 3 to be cleaned. The impellers 12 absorb forces which are exerted by a suction pipe to be connected to the suction nozzle 11, to be guided by hand, or a vacuum cleaner to be connected to it. Due to the interposition of the tubular swivel joint 9, these forces have practically no effect on the nozzle body 1.

In der den Düsenkörper 1 nach oben überdekkenden Oberseite 13.2 einer Haube befindet sich ein Ausschnitt 13, der das dort angeordnete Rohrschwenkgelenk mit der Schwenkachse 7 und den anschließenden Teil des Absaugrohrstückes 6 nach oben frei läßt. Als Abschluß für diesen Ausschnitt 13 ist eine Abdeckkappe 14 vorgesehen, die der Kontur des Ausschnitts 13 angepaßt und auf der in der Betriebslage obenliegenden Seite des Absaugrohrstücks 6 lösbar von oben aufzusetzen und daran festzusetzen ist. Hierfür weist die Abdeckkappe 14 an ihren in Richtung der Schwenkachse gegenüberliegenden Seitenrändern Seitenwangen 15 auf, die senkrecht zur Schwenkachse 7 stehen und Rastmittel 16 tragen, welche mit Gegenrasten 17 an Haltestegen 17.1 am Absaugrohrstück 6 lösbar in Eingriff stehen bzw. zu bringen sind. Die Oberseite der Abdeckkappe 14 ist rechteckförmig ausgebildet und weist eine Breite auf, die mindestens dem Abstand der äußeren Stirnflächen der Laufräder 12 entspricht. Dabei erstreckt sich die Abdeckkappe 14 vom Düsenkörper 1 aus über die Mitte der Laufräder 12 hinweg und deckt zugleich den nach oben gerichteten Spalt des Rohrschwenkgelenks 9 ab. Dabei greifen die Seitenwangen 15 vor die Stirnflächen der Laufräder 12, decken dieselben jedoch nur zu einem Bruchteil seitlich ab. An der gegenüberliegenden Seite greift die Abdeckkappe 14 mit ihrer parallel zur Schwenkachse 7 verlaufenden Kante 18 in den Ausschnitt 13 ein, untergreift eine benachbarte Kante 13.1 dieses Ausschnitts 13 und taucht bei einer Verschwenkung des Absaugrohrstücks 6 gegenüber dem Düsenkörper 1 unter die betreffende vorn liegende Kante 13.1 bzw. die Oberseite 13.2 der den Düsenkörper 1 nach oben abdeckenden Haube. Dadurch ist auch die mit dieser Kante etwa auf gleicher Höhe liegende Dichtlippe 8 von der Abdeckkappe 14 gegen Beschädigungen geschützt, die durch Anstoßen an Möbelkanten oder dgl. beim Saugen auftreten können.In the top 13.2 of a hood, which covers the nozzle body 1 upwards, there is a cutout 13 which leaves the pipe swivel joint arranged there with the swivel axis 7 and the adjoining part of the suction pipe piece 6 free upwards. As a conclusion for this cutout 13, a cover cap 14 is provided which is adapted to the contour of the cutout 13 and can be detachably placed on the side of the suction tube piece 6 lying in the operating position from above and fixed thereon. For this purpose, the cover cap 14 has, at its side edges opposite in the direction of the pivot axis, side cheeks 15 which are perpendicular to the pivot axis 7 and carry latching means 16, which have counter latches 17 are releasably engaged or to be brought into place on holding bars 17.1 on the suction pipe section 6 The top of the cover cap 14 is rectangular and has a width which corresponds at least to the distance between the outer end faces of the impellers 12. The cover cap 14 extends from the nozzle body 1 over the center of the impellers 12 and at the same time covers the upward gap of the tubular swivel joint 9. The side cheeks 15 engage in front of the end faces of the impellers 12, but cover them to the side only to a fraction. On the opposite side, the covering cap 14 engages in the cutout 13 with its edge 18 running parallel to the pivot axis 7, engages under an adjacent edge 13.1 of this cutout 13 and, when the suction pipe piece 6 is pivoted relative to the nozzle body 1, dips under the relevant front edge 13.1 or the top 13.2 of the hood covering the nozzle body 1 upwards. As a result, the sealing lip 8, which is located approximately at the same height with this edge, is also protected by the cover cap 14 against damage which may occur due to bumping against furniture edges or the like during suction.
