Description

Die Erfindung betrifft ein Staubsaugermundstück gemäß dem Oberbegriff des Anspruches 1.The invention relates to a vacuum cleaner mouthpiece according to the preamble of claim 1.

Ein solches Staubsaugermundstück ist durch die DE-PS 30 09 648 bekannt. Bei diesem Mundstück ist das verschwenkbar am Zwischenkanalteil angeordnete Mundstückteil vollkommen von der senkrechten Komponente des über den Handhabungsstiel auf das Mundstück ausgeübten Kraft entkoppelt. Das Mundstückteil stellt sich daher beim Saugen entsprechend der jeweiligen Bewegungsrichtung des Mundstückes leicht schräg und zwar so, daß die im bezug auf die Bewegungsrichtung jeweils vordere Begrenzungskante des Saugkanales auf die zu reinigende Fläche zu gekippt wird. Damit dringt diese Kante beim Reinigen von Teppichen stärker in den Teppichflor ein, was zu einer Erhöhung der Schiebekraft führt. Infolge der Schrägstellung des Mundstückteiles kann es auch leicht zum sogenannten Rattern des Mundstückteiles kommen.Such a vacuum cleaner mouthpiece is known from DE-PS 30 09 648. In the case of this mouthpiece, the mouthpiece part which is pivotably arranged on the intermediate channel part is completely decoupled from the vertical component of the force exerted on the mouthpiece via the handling handle. The mouthpiece part is therefore slightly inclined when sucking in accordance with the respective direction of movement of the mouthpiece, in such a way that the front boundary edge of the suction channel in relation to the direction of movement is tilted toward the surface to be cleaned. This edge penetrates more strongly into the carpet pile when cleaning carpets, which increases the pushing force. As a result of the inclination of the mouthpiece part, so-called rattling of the mouthpiece part can easily occur.

Der Erfindung liegt die Aufgabe zugrunde, ein Staubsaugermundstück der gattungsgemäßen Art so weiterzubilden, daß das Mundstückteil beim Reinigen kippfrei über die zu reinigende Fläche bewegbar ist.The invention has for its object to develop a vacuum cleaner mouthpiece of the generic type so that the mouthpiece part can be moved over the surface to be cleaned without tilting during cleaning.

Die Lösung der gestellten Aufgabe gelingt durch die im Kennzeichen des Anspruches 1 angegebenen Merkmale. Bei einer solchen Ausbildung des Staubsaugermundstückes wird wegen des Achsabstandes zwischen der Schwenkachse des Ansaugstutzens und der Drehachse der Tragrolle durch die auf den Handhabungsstiel ausgeübte Kraft ein auf den Zwischenkanalteil wirkendes Kippmoment erzeugt. Dieses Kippmoment wiederum hat eine entsprechende Andrückkraft des Mundstückteiles an die zu reinigende Fläche zur Folge. Infolge der Lage der Kippachse wirkt diese Andrückkraft im wesentlichen auf die hinteren Stützauflagen des Mundstückteiles, so daß einem nach Vornekippen des Mundstückteiles entgegengewirkt wird. Somit wird ein stabiles Gleitverhalten des Mundstückteiles auf unterschiedlichen Bodenbelägen erreicht.The problem is solved by the features specified in the characterizing part of claim 1. In such a configuration of the vacuum cleaner mouthpiece, a tilting moment acting on the intermediate channel part is generated because of the center distance between the pivot axis of the suction nozzle and the axis of rotation of the support roller due to the force exerted on the handle. This tilting moment in turn has a corresponding pressing force of the mouthpiece part against the surface to be cleaned Episode. As a result of the position of the tilt axis, this pressing force essentially acts on the rear support supports of the mouthpiece part, so that one counteracts after the mouthpiece part tilts forward. A stable sliding behavior of the mouthpiece part on different floor coverings is thus achieved.

Die Anlenkung des Mundstückteiles erfolgt an einem an der Unterseite des Gehäuses des Zwischenkanalteiles angeformten Ansatz. Auf diese Weise läßt sich am einfachsten die notwendige tiefe Lage der Kippachse erreichen.The mouthpiece part is articulated on an attachment molded onto the underside of the housing of the intermediate channel part. This is the easiest way to achieve the necessary deep position of the tilt axis.

Zur Verminderung der Schiebekraft ist es vorteilhaft, daß als Stützauflagen an jeder Längsseite des Mundstückteiles zwei Rollen vorgesehen sind.To reduce the pushing force, it is advantageous that two rollers are provided as support pads on each long side of the mouthpiece part.

Um bei mit einer gleichmäßigen Fugenstruktur (Kachelböden) versehenen Böden ein gleichzeitiges Eintauchen aller Rollen des Mundstückteiles in die Fugen zu vermeiden, sind die auf der einen Längsseite des Mundstückteiles angeordneten Rollen gegenüber den auf der anderen Längsseite angeordneten Rollen in Längsrichtung des Mundstückteiles achsversetzt. Durch eine höhenverstellbare Anordnung der Rollen des Mundstückteiles wird ein selbsttätiges Einstellen des Abstandes zwischen der Unterseite des Mundstückteiles und der zu reinigenden Fläche in Abhängigkeit von dem am Mundstückteil wirkenden Unterdruck und der über den Handhabungsstiel ausgeübten Andrückkraft erreicht.In order to avoid simultaneous immersion of all rollers of the mouthpiece part in the joints in the case of floors provided with a uniform joint structure (tile floors), the rollers arranged on one long side of the mouthpiece part are axially offset in the longitudinal direction of the mouthpiece part compared to the rollers arranged on the other long side. Through a height-adjustable arrangement of the rollers of the mouthpiece part, an automatic adjustment of the distance between the underside of the mouthpiece part and the surface to be cleaned is achieved as a function of the negative pressure acting on the mouthpiece part and the pressing force exerted on the handle.

Die Aufnahme von Fäden und Flusen wird dadurch wesentlich verbessert, daß an dem Mundstückteil vor und hinter dem Saugkanal ballig ausgebildete Fadenheber in einem zu den äußeren Längsseiten des Mundstückteiles hin ansteigenden Neigungswinkel gegenüber der Auflageebene des Mundstückteiles angeordnet sind.The inclusion of threads and fluff is significantly improved in that thread-shaped thread lifters are arranged on the mouthpiece part in front of and behind the suction channel in an inclination angle that increases towards the outer longitudinal sides of the mouthpiece part relative to the support plane of the mouthpiece part.

Dadurch, daß die den Saugkanal begrenzenden Arbeitskanten im Bereich der Fadenheber auf gleiche Höhe durchgezogen sind, er folgt auch im Bereich der Fadenheber eine die Schmutzaufnahme verbesserende mechanische Bearbeitung des Teppichflores.Characterized in that the working edges delimiting the suction channel are pulled through at the same height in the area of the thread lifter, he mechanical processing of the carpet pile also improves the dirt pick-up in the area of the thread lifter.

Eine Steigerung des Unterdruckes im Saugkanal des Mundstückteiles ist dadurch erzielbar, daß nach der hinteren Arbeitskante des Saugkanales eine sich zumindest über eine Teillänge des Mundstückteiles erstreckende elastische Schürze angeordnet ist.An increase in the negative pressure in the suction channel of the mouthpiece part can be achieved in that an elastic apron extending at least over a partial length of the mouthpiece part is arranged after the rear working edge of the suction channel.

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

  • FIG 1 ein Staubsaugermundstück im Schnitt,
  • FIG 2 eine Unteransicht des Staubsaugermundstückes.
The subject of the application is described in more detail below using an exemplary embodiment shown in the drawing. It shows:
  • 1 shows a vacuum cleaner mouthpiece in section,
  • 2 shows a bottom view of the vacuum cleaner mouthpiece.

Ein mit 1 bezeichnetes Staubsaugermundstück weist einen Zwischenkanalkeil 2, ein Mundstückteil 3 und einen Anschlußstutzen 4 auf. Das Mundstückteil 3 ist an einem am einen Ende des Zwischenkanalteiles 2 an der Unterseite von dessen Gehäuse angeformten Ansatz 5 um eine Kippachse 6 kippbar angelenkt. Am anderen Ende des Zwischenkanalteiles 2 ist der Anschlußstutzen 4 um eine Schwenkachse 7 höhenverschwenkbar mit dem Zwischenkanalteil 2 verbunden. An diesem Ende des Zwischenkanalteiles 2 sind ferner an dessen Seitenwänden nach außen abstehende Lagerzapfen 8 angeformt, auf denen jeweils eine tonnenförmig ausgebildete Tragrolle 9 drehbar gelagert ist. Die Mittelachse der Lagerzapfen 8 bildet somit die Drehachse 10 für die Tragrollen 9. Die Tragrollen 9 sind durch eine Rastverbindung 11 in axialer Richtung auf den Lagerzapfen 8 gesichert. Im Bereich ihres größten Durchmessers sind die Tragrollen 9 mit einer weichen Auflage 12 versehen.A vacuum cleaner mouthpiece designated 1 has an intermediate channel wedge 2, a mouthpiece part 3 and a connecting piece 4. The mouthpiece part 3 is articulated on a projection 5 integrally formed on one end of the intermediate channel part 2 on the underside of its housing, about a tilt axis 6. At the other end of the intermediate duct part 2, the connecting piece 4 is connected to the intermediate duct part 2 such that it can be pivoted in height about a pivot axis 7. At this end of the intermediate channel part 2, outwardly projecting bearing pins 8 are also formed on the side walls thereof, on each of which a barrel-shaped support roller 9 is rotatably mounted. The central axis of the bearing pin 8 thus forms the axis of rotation 10 for the support rollers 9. The support rollers 9 are secured to the bearing pin 8 in the axial direction by a latching connection 11. In the area of their largest diameter, the support rollers 9 are provided with a soft pad 12.

Das Mundstückteil 3 weist einen Saugkanal 13 auf, der sich von den Querseiten 14 des Mundstückteiles 3 ausgehend zu dessen Quermittelachse 15 hin stetig erweitert. Ein am Mundstückteil 3 vorgesehener und entsprechend dem Kippradius des Mundstück teiles 3 bogenförmig ausgebildeter Saugstutzen 16 greift in das ebenfalls entsprechend bogenförmig ausgebildete eine Ende 17 des Zwischenkanalteiles 2 ein. Der Saugkanal 13 kann somit über seinen Saugstutzen 16, den Zwischenkanalteil 2, den Anschlußstutzen 4 und eine an diesen ansteckbare Saugleitung mit einem Staubsauger in Saugverbindung gebracht werden.The mouthpiece part 3 has a suction channel 13 which, starting from the transverse sides 14 of the mouthpiece part 3, continuously widens towards its transverse central axis 15. A provided on the mouthpiece part 3 and corresponding to the tilt radius of the mouthpiece Part 3 arcuate suction nozzle 16 engages in the correspondingly arcuate one end 17 of the intermediate channel part 2. The suction channel 13 can thus be brought into suction connection with a vacuum cleaner via its suction nozzle 16, the intermediate channel part 2, the connecting piece 4 and a suction line which can be plugged onto the latter.

Am Mundstückteil 3 sind in dessen Eckbereichen vier Rollen 18 und 19 drehbar angeordnet. Hierbei sind die auf der einen Längsseite des Saugkanales 13 angeordneten Rollen 18 gegenüber den auf der anderen Längsseite angeordneten Rollen 19 in Richtung der Längsmittelachse 20 des Mundstückteiles 3 gleichmäßig versetzt. Die Rollen 18 und 19 stützen das Mundstückteil 3 auf der abzusaugenden Fläche ab, so daß die den Saugkanal 13 begrenzenden vorderen und hinteren Arbeitskanten 21 und 22 in einem kleinen Abstand 23 über der abzusaugenden Fläche liegen. Werden die Rollen 18 und 19 höhenverstellbar im Mundstückteil 3 angeordnet, so können diese bei entsprechendem, am Mundstückteil 3 wirkenden Unterdruck soweit nach oben bewegt werden, daß die Arbeitskanten 21 und 22 auf der abzusaugenden Fläche aufliegen. Da beim Saugen von Teppichen am Mundstückteil 3 ein wesentlich höherer Unterdruck auftritt als beim Saugen von glatten Böden, wird somit beim Reinigen eines Teppichbodens selbsttätig der Eingriff der Arbeitskanten 21 und 22 in den Teppichflor erreicht.Four rollers 18 and 19 are rotatably arranged on the mouthpiece part 3 in the corner regions thereof. Here, the rollers 18 arranged on one long side of the suction channel 13 are evenly offset in the direction of the longitudinal central axis 20 of the mouthpiece part 3 compared to the rollers 19 arranged on the other long side. The rollers 18 and 19 support the mouthpiece part 3 on the surface to be suctioned off, so that the front and rear working edges 21 and 22 delimiting the suction channel 13 lie at a small distance 23 above the surface to be suctioned off. If the rollers 18 and 19 are arranged in a height-adjustable manner in the mouthpiece part 3, they can be moved upwards with a corresponding negative pressure acting on the mouthpiece part 3 so that the working edges 21 and 22 rest on the surface to be suctioned off. Since a significantly higher vacuum occurs when vacuuming carpets on the mouthpiece part 3 than when vacuuming smooth floors, the engagement of the working edges 21 and 22 in the carpet pile is thus automatically achieved when cleaning a carpet.

Im Mittenbereich des Mundstückteiles 3 sind beidseitig zu dessen Saugkanal 13 Fadenheber 24 und 25 angeordnet. Wie aus FIG 1 erkennbar ist, ist zumindest der vordere Fadenheber 24 ballig ausgebildet und nach außen schräg ansteigend am Mundstück 3 angeordnet. Zur Erhöhung des am Mundstückteil 3 wirksam werdenden Unterdruckes ist nach der hinteren Arbeitskante 22 zu beiden Seiten des hinteren Fadenhebers 25 jeweils eine elastische Schürze 26 angeordnet, die mit ihrem freien Ende auf der abzusaugenden Fläche schleift und somit den Raum unter dem Mundstückteil 3 zu dessen Rückseite hin abdichtet.In the central area of the mouthpiece part 3 13 thread lifters 24 and 25 are arranged on both sides of its suction channel. As can be seen from FIG. 1, at least the front thread lifter 24 is of spherical design and is arranged on the mouthpiece 3 so as to rise obliquely outwards. To increase the vacuum acting on the mouthpiece part 3, an elastic apron 26 is arranged after the rear working edge 22 on both sides of the rear thread lifter 25, the free end of which is to be suctioned off Surface grinds and thus seals the space under the mouthpiece part 3 to the rear.

Wie die Schnittdarstellung nach FIG 1 zeigt, liegt die Kippachse 6 des Mundstückteiles 3 höhenmäßig unterhalb der Drehachse 10 der Tragrollen 9 und ist ferner in waagrechter Richtung vor den die hinteren Stützauflagen bildenden Rollen 19 zur Längsmittelachse 20 hin angeordnet. Die Lage der Kippachse 6 ist dabei so gewählt, daß die Verlängerung 28 der zwischen der Schwenkachse 7 und der Kippachse 6 gezogenen Verbindungslinie 27 die Auflageebene 29 des Mundstückteiles 3 in dem Bereich zwischen der Längsmittelachse 20 und dem Auflagepunkt 30 der hinteren Rollen 19 schneidet. Infolge des Achsabstandes 31 zwischen der Schwenkachse 7 und der Drehachse 10 wird durch die waagerechte Komponente der auf das Staubsaugermundstück 1 ausgeübten Schiebekraft ein Kippmoment auf das Zwischenkanalteil 2 ausgeübt. Dieses Kippmoment erzeugt am Mundstückteil 3 eine senkrecht gerichtete Kraft, welche über die Kippachse 6 in das Mundstückteil 3 eingeleitet wird und dieses gegen die abzusaugende Fläche drückt. Durch die beschriebene Lage der Kippachse 6 wird eine Ausgewogenheit der verschiedenen am Mundstückteil 3 angreifenden Kräfte erzielt, so daß ein stabiles Gleitverhalten des Mundstückes gewährleistet ist.As the sectional view according to FIG. 1 shows, the tilt axis 6 of the mouthpiece part 3 is located below the axis of rotation 10 of the support rollers 9 and is furthermore arranged in a horizontal direction in front of the rollers 19 forming the rear support supports towards the longitudinal central axis 20. The position of the tilt axis 6 is chosen so that the extension 28 of the connecting line 27 drawn between the pivot axis 7 and the tilt axis 6 intersects the support plane 29 of the mouthpiece part 3 in the area between the longitudinal central axis 20 and the support point 30 of the rear rollers 19. As a result of the center distance 31 between the pivot axis 7 and the axis of rotation 10, a tilting moment is exerted on the intermediate channel part 2 by the horizontal component of the pushing force exerted on the vacuum cleaner mouthpiece 1. This tilting moment generates a vertically directed force on the mouthpiece part 3, which force is introduced into the mouthpiece part 3 via the tilting axis 6 and presses it against the surface to be extracted. The described position of the tilt axis 6 achieves a balance of the various forces acting on the mouthpiece part 3, so that a stable sliding behavior of the mouthpiece is ensured.
