Der Erfindung liegt die Aufgabe zugrunde, ein Abstreifelement für Staubsaugerdüsen anzugeben, das sich sowohl durch gute Trockensaugeigenschaften als auch gute Naßsaugeigenschaften auf glatten Böden auszeichnet.The invention has for its object a stripping element to specify for vacuum cleaner nozzles that both due to good dry suction properties as well as good wet suction properties distinguished on smooth floors.
Gegenstand der Erfindung und Lösung dieser Aufgabe ist ein
Abstreifelement, bestehend aus einer Bürstenleiste und
einem Schaber aus einem elastomeren Material, der mit der
Bürstenleiste eine in eine Aufnahmenut an der Unterseite
der Staubsaugerdüse befestigbare Funktionseinheit bildet,
Der Schaber besteht aus Gummi oder Kunststoff und ist biegsam ausgebildet. An der Unterseite steht er geringfügig, z.B. ca. 1 mm, gegenüber der Bürstenleiste vor. Je nach Bewegungsrichtung der Staubsaugerdüse legt sich die Wischkante in der einen oder anderen Richtung um. Die Bürstenleiste begrenzt die Umlenkbewegung jedoch in einer Richtung und führt gleichsam zu einer Versteifung des Schabers in dieser Bewegungsrichtung. Das erlaubt es, den Schaber sehr flexibel auszubilden. Die Öffnungen des Schabers und die den Öffnungen zugeordneten Ausklinkungen der Bürstenleiste ermöglichen einen wirksamen Eintritt der Saugluft, wobei von dem Bürstenstreifen aufgenommene Partikel im Luftstrom abgelöst und mit dem Saugluftstrom abgeführt werden. Darüber hinaus sind die Öffnungen in unmittelbarer Nähe der Wischkante so angeordnet, daß stauende Nässe einen Durchlaß findet. Flüssigkeitsansammlungen auf dem zu reinigenden Boden sind in einer Vorwärts- und/oder Rückwärtsbewegung des Saugkopfes überfahrbar und können, sobald sie in den Arbeitsbereich der Staubsaugerdüse gelangen, im Saugluftstrom aufgenommen und abgeführt werden. Ein auf dem zu reinigenden Boden verbleibender Flüssigkeitsfilm wird von der Wischkante des Schabers erfaßt und im Saugluftstrom abgesaugt. Im Ergebnis ermöglicht das erfindungsgemäße Abstreifelement ein wirkungsvolles Trockensaugen und Naßsaugen auf glatten Böden.The scraper is made of rubber or plastic and is flexible. It stands slightly on the bottom, e.g. approx. 1 mm, in front of the brush strip. Each according to the direction of movement of the vacuum cleaner nozzle Wipe edge in one direction or the other. The Brush strip limits the deflection movement in one Direction and leads to a stiffening of the Scraper in this direction of movement. That allows the Training scraper very flexibly. The openings of the Scraper and the notches associated with the openings the brush strip allow an effective entry of the Suction air, being taken up by the brush strip Particles detached in the air flow and with the suction air flow be dissipated. In addition, the openings are in in the immediate vicinity of the wiping edge so that stagnant moisture finds a passage. Fluid retention on the floor to be cleaned are in a forward and / or backward movement of the suction head can be run over and can as soon as they are in the work area of the vacuum cleaner nozzle arrive, taken up in the suction air flow and discharged become. One remaining on the floor to be cleaned Liquid film is captured by the wiping edge of the scraper and extracted in the suction air flow. As a result, enabled the stripping element according to the invention an effective Dry vacuuming and wet vacuuming on smooth floors.
In weiterer Ausgestaltung lehrt die Erfindung, daß der Schaber aus einer kopfseitigen Verdickung und einer daran angeformten biegsamen Abziehlippe besteht, wobei die kopfseitige Verdickung an der Bürstenleiste anliegt und wobei die Abziehlippe, welche die Wischkante aufweist sowie die Öffnungen enthält, mit Abstand frei beweglich zur Bürstenleiste ausgerichtet ist. Die Bürstenleiste weist zweckmäßig eine die Borsten einfassende Kopfleiste auf. Vorzugsweise ist die Anordnung so getroffen, daß die kopfseitige Verdickung des Schabers an einem Schenkel dieser Kopfleiste anliegt sowie die Oberseite der Kopfleiste umfaßt. Die kopfseitige Verdickung des Schabers sowie die Kopfleiste der Bürstenleiste können z.B. durch Verklebung miteinander verbunden sein. Jedenfalls sind die Kopfleiste der Bürstenleiste sowie die kopfseitige Verdickung des Schabers gemeinsam in eine Aufnahmenut an der Unterseite der Staubsaugerdüse gehalten. Die Aufnahmenut kann an einer gehäusefesten Sohle angeordnet sein, sie kann aber auch Teil einer heb- und senkbaren Anordnung sein. In weiterer Ausgestaltung lehrt die Erfindung, daß die kopfseitige Verdickung des Schabers und das obere Ende der Bürstenleiste in die Aufnahmenut einer Klemmleiste eingespannt sind, die einen die flexible Abziehlippe an ihrer zur Bürstenleiste abgewandten Außenseite oberhalb der Öffnungen stützende Schenkel aufweist. Die Klemmleiste ist beispielsweise heb- und senkbar innerhalb des Saugkopfes der Staubsaugerdüse untergebracht und kann mittels einer Betätigungseinrichtung ein- und ausgefahren werden.In a further embodiment, the invention teaches that the Scraper with a thickening on the top and one on it integrally formed flexible pull lip, the thickening on the brush bar and the pull-off lip which has the wiping edge and the openings contains, freely movable to the distance Brush strip is aligned. The brush strip points expediently a head strip enclosing the bristles. The arrangement is preferably such that the head-end thickening of the scraper on one leg this top bar is applied as well as the top of the Includes header. The thickening of the scraper at the top as well as the head strip of the brush strip can e.g. by Adhesive bonded together. Anyway, they are Head strip of the brush strip and the thickening on the head side of the scraper together in a receiving groove on the Bottom of the vacuum cleaner nozzle held. The receiving groove can be arranged on a housing-fixed sole, it can but also be part of a raised and lowered arrangement. In Another embodiment teaches the invention that the head Thickening of the scraper and the top of the Brush strip clamped in the receiving groove of a terminal strip are those who have the flexible pull-off lip on theirs outside of the brush strip facing away from the Has openings supporting legs. The terminal block is for example, can be raised and lowered within the suction head the vacuum cleaner nozzle and can by means of a Actuating device can be retracted and extended.

Das in den Figuren dargestellte Abstreifelement 1 besteht
aus einer Bürstenleiste 2 und einem Schaber 3 aus einem
elastomeren Material, z.B. aus Gummi oder einem flexiblen
Kunststoff. Die Bürstenleiste 2 und der Schaber 3 sind
unmittelbar hintereinander angeordnet und bilden eine
Funktionseinheit, die in einer Aufnahmenut 4 an der in Fig.
1 nur angedeuteten Unterseite einer Staubsaugerdüse
befestigbar ist. Einer vergleichenden Betrachtung der Fig.
1 und 2 entnimmt man, daß der Schaber 3 eine gegenüber der
Bürstenleiste 2 unterseitig vorstehende glatte Wischkante 5
sowie oberhalb der Wischkante 5 in Längsrichtung gereihte
Öffnungen 6 aufweist. Im Bereich dieser Öffnungen 6 ist die
Bürstenleiste 2 mit Ausklinkungen 7 versehen (Fig. 3). Die
Wischkante 5 steht etwa 0,5 bis 2 mm an der Unterseite der
Bürstenleiste 2 vor. Der Schaber 3 ist flexibel und legt
sich je nach Bewegungsrichtung der Staubsaugerdüse nach
außen von der Bürstenleiste 2 weg oder nach innen zur
Bürstenleiste 2 hin um. Die Bürstenleiste 2 begrenzt die
Umlenkbewegung des Schabers 3 in der einen Richtung und
verhindert, daß der Schaber 3 unter der Saugwirkung der
Staubsaugerdüse vom Boden abhebt. Der Schaber 3 kann daher
aus sehr flexiblem Material gefertigt werden. Der Fig. 1
entnimmt man, daß der Schaber 3 im Ausführungsbeispiel und
nach bevorzugter Ausführungsform der Erfindung aus einer
kopfseitigen Verdickung 8 und einer daran angeformten
biegsamen Abziehlippe 9 besteht, wobei die kopfseitige
Verdickung 8 an der Bürstenleiste 2 anliegt und wobei die
Abziehlippe 9 mit Abstand frei beweglich zur Bürstenleiste
2 ausgerichtet ist. Der Fig. 1 entnimmt man ferner, daß die
Bürstenleiste 2 eine die Borsten einfassende Kopfleiste 10
aufweist und daß die kopfseitige Verdickung 8 des Schabers
3 einerseits an einem Schenkel der Kopfleiste 10 anliegt
und andererseits die Oberseite der Kopfleiste 10 umfaßt.
Die Kopfleiste 10 sowie die kopfseitige Verdickung 8 des
Schabers 3 können fest miteinander verbunden, z.B. verklebt,
sein. Jedenfalls sind sie gemeinsam in die Aufnahmenut
4 an der Unterseite der Staubsaugerdüse eingesetzt. Im
Ausführungsbeispiel besteht die Aufnahmenut 4 aus einer
Klemmleiste 11, die einen die flexible Abziehlippe an ihrer
zur Bürstenleiste 2 abgewandten Außenseite oberhalb der
Öffnungen 6 stützenden Schenkel 11' aufweist. Dieser Schenkel
11' begrenzt die Umlenkbewegung der Abziehlippe 9 nach
außen und trägt dazu bei, daß die Abziehlippe 9 mit ausreichender
Andrückkraft auf dem zu reinigenden Boden aufliegt,
wenn die Staubsaugerdüse (in Fig. 1 nach rechts)
bewegt wird.The
Der Schaber 3 kann oberhalb der Öffnungen 6 auch einen Steg
12 aufweisen, der an der von der Bürstenleiste 2 abgewandten
Außenseite angeformt ist und an der Gehäusewand
13 der Staubsaugerdüse anliegt.The
In Fig. 4 ist ein Einbaubeispiel für das erfindungsgemäße
Abstreifelement 1 dargestellt. Die in Fig. 4 dargestellte
Staubsaugerdüse ist für das Trockensaugen auf Teppichböden,
für das Trockensaugen auf Glattböden sowie für das
Naßsaugen auf Glattböden eingerichtet und besteht in ihrem
Aufbau aus einem Saugkopf 14 mit einer Bodenplatte 15, die
einen bodenseitig offenen, kanalförmigen Saugmund 16 aufweist
und mit Saugmundkanten sowie Fadenhebern zum Trockensaugen
von Teppichböden ausgerüstet ist. Das erfindungsgemäße
Abstreifelement 1 ist in Bewegungsrichtung der
Staubsaugerdüse vor dem Saugmund 16 angeordnet und an einen
Halter 17 angeschlossen, der im Saugkopf 14 heb- und
senkbar angeordnet ist. Durch eine Betätigungseinrichtung
18 ist das Abstreifelement 1 mit dem Halter 17 ein- und
ausfahrbar. Der flexible Schaber 3 ist außenseitig, die
Bürstenleiste 2 innenseitig zum Saugmund 16 der
Staubsaugerdüse hin angeordnet. Zum Saugen von Glattböden
wird das Abstreifelement 1 ausgefahren, wobei die Bürstenleiste
2 auf dem zu reinigenden Boden aufliegt. Die
Abziehlippe 9 des Schabers 3 liegt ebenfalls an dem Boden
an und wird bei einer Vorwärtsbewegung der Staubsaugerdüse
nach innen, zum Bürstenstreifen 2 hin umgelenkt. Die
Umlenkbewegung ist durch den verhältnismäßig steifen
Bürstenstreifen 2 jedoch begrenzt. Dieser verhindert auch,
daß die biegsame Abziehlippe 9 unter der Saugwirkung von
dem Boden abhebt.4 is an installation example for the
In dem in Fig. 4 dargestellten Ausführungsbeispiel ist
hinter dem Saugmund 16 eine Gummileiste 19 fest an der
Unterseite des Saugkopfes 14 angeordnet. Im Rahmen der
Erfindung liegt es, an dieser Stelle ebenfalls ein erfindungsgemäß
ausgebildetes Abstreifelement 1, bestehend aus
Bürstenleiste 2 und Schaber 3, anzuordnen. Das hintere
Abstreifelement kann, wie in Fig. 4 dargestellt, höhenfest
an dem Saugkopf angeordnet sein. Es ist ferner möglich, ein
vorderes und hinteres Abstreifelement, jeweils erfindungsgemäß
ausgebildet, an eine Halteplatte anzuschließen, die
in dem Saugkopf heb- und senkbar angeordnet ist und mittels
einer Betätigungsvorrichtung ein- und ausgefahren werden
