des Patentanspruchs 1.The invention relates to a vacuum cleaner nozzle according to the preamble
of
Eine solche Staubsaugerdüse ist bereits aus FR-A- 1422936 bekanntSuch a vacuum cleaner nozzle is already known from FR-A-1422936
Staubsaugerdüsen der hier in Rede stehenden Art sind üblicherweise mehrteilig ausgeführt. Der Düsenkörper selbst ist dabei regelmäßig als Kunststoffgehäuse ausgebildet und dient neben seiner Funktion als durchströmtes Bauteil als Träger für sämtliche Funktionseinheiten der Düse. Das Düsengehäuse wird nach unten, d.h. in Richtung zum zu saugenden Boden durch eine Gleitsohle aus Stahlblech abgeschlossen, in der Strömungskanäle zur Erzielung einer optimalen Saugwirkung und eines optimalen Schmutzpartikeltransportes eingeformt sind. Dabei sind die Strömungskanäle durch wulstartig hervortretende Saugabrißkanten zur Erzielung einer optimalen Staubaufnahme umgeben. Weiter ist im Bereich der Gleitsohle üblicherweise eine Borstenträgerplatte angeordnet, welche mittels im Gehäuse gelagerter und angeordneter Treter in unterschiedliche Stellungen für unterschiedliche Bodenbeläge umgeschaltet werden kann.Vacuum cleaner nozzles of the type in question here are common executed in several parts. The nozzle body itself is included regularly designed as a plastic housing and serves alongside its function as a flow-through component as a carrier for everyone Functional units of the nozzle. The nozzle housing is after below, i.e. towards the floor to be sucked by a Sliding sole made of sheet steel completed in the Flow channels for optimal suction and optimal dirt particle transport are molded. The flow channels are protruding through bulges Vacuum tear-off edges for optimal dust absorption surround.

Hinsichtlich ihrer Funktionsfähigkeit zeigen diese bekannten Düsen durchaus zufriedenstellende Gebrauchseigenschaften. Es ist jedoch ein Nachteil dieser bekannten Düsen, daß die Zusammensetzung aus einer relativ großen Zahl von Bauteilen und Funktionseinheiten einen relativ großen Fertigungs- und insbesondere Montageaufwand bedingt. Dies ist insbesondere deshalb von Bedeutung, da es sich bei einer gattungsgemäßen Staubsaugerdüse um ein Erzeugnis der industriellen Massenfertigung handelt, wo die Stückkosten von ausschlaggebender Bedeutung sind.With regard to their functionality, these show known ones Nozzles quite satisfactory performance. It However, a disadvantage of these known nozzles is that the Composed of a relatively large number of components and functional units a relatively large manufacturing and in particular due to assembly work. This is particularly so important because it is a generic Vacuum cleaner nozzle around a product of industrial mass production deals where the unit cost of crucial Meaning.
Ausgehend von diesem Stand der Technik ist es die Aufgabe der
vorliegenden Erfindung, eine Staubsaugerdüse nach dem Oberbegriff
des Patentanspruchs 1 zu schaffen, bei der der
Fertigungs- und Montageaufwand bei im wesentlichen gleichbleibenden
Gebrauchseigenschaften verringert ist.Based on this state of the art, it is the task of
present invention, a vacuum cleaner nozzle according to the preamble
of
Diese Aufgabe wird durch eine Staubsaugerdüse nach der Lehre
des Patentanspruchs 1 gelöst.This task is done by a vacuum cleaner nozzle according to the teaching
of
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of Subclaims.
Erfindungsgemäß weist die Staubsaugerdüse einen Düsenkörper und eine den Düsenkörper nach unten abschließende Bodenplatte auf. Die Bodenplatte dient dabei als Gleitplatte, wobei der Begriff "Gleitplatte" im Sinne der vorliegenden Erfindung auch eine Gestaltung mit einschließt, bei der die Platte zur besseren Führung mit Rollkörpern, insbesondere Laufrollen oder Rädern, versehen ist. Im Gegensatz zu den bekannten Staubsaugerdüsen, bei denen der Düsenkörper und die Gleitplatte als separate Bauteile ausgeführt sind, sind gemäß der Erfindung der Düsenkörper und die Bodenplatte als einstückiger Träger ausgeführt. Vorzugsweise besteht ein derartiger Träger aus Kunststoff und ist insbesondere durch Spritzgießen oder Formpressen hergestellt.According to the vacuum cleaner nozzle has a nozzle body and a bottom plate that closes the nozzle body downward on. The base plate serves as a sliding plate, the The term "sliding plate" in the sense of the present invention also includes a design in which the plate for better guidance with rolling elements, in particular rollers or Wheels, is provided. In contrast to the known vacuum cleaner nozzles, where the nozzle body and the slide plate as separate components are executed are according to the invention the nozzle body and the base plate as a one-piece carrier executed. Such a carrier preferably consists of Plastic and is especially by injection molding or Molding presses made.
In die Bodenplatte und damit in den einstückigen Träger sind der zentrale Saugkanal und mindestens ein Strömungskanal zur Verteilung der Saugleistung und zur besseren Abführung der Schmutzpartikel unmittelbar bei der Herstellung des Trägers eingeformt. Dabei ist der Strömungskanal nach unten, d.h. zum zu saugenden Boden hin, offen ausgebildet. Der Strömungskanal mündet in den Saugkanal, der wiederum mit einem Saugrohranschlußstutzen strömungsdurchlässig verbunden ist. In the base plate and thus in the one-piece support the central suction channel and at least one flow channel for Distribution of suction power and for better removal of the Dirt particles immediately during the manufacture of the carrier molded. The flow channel is down, i.e. to the floor open to suction. The flow channel opens into the suction channel, which in turn has a suction pipe connection piece is connected to flow.
Weiter sind erfindungsgemäß in die Bodenplatte des Trägers Dicht- bzw. Abschlußelemente, die zum einen zur Beibehaltung eines mehr oder weniger genau definierten Abstandes der Bodenplatte vom zu saugenden Boden und zum anderen zur zumindest teilweise dichtenden Abgrenzung des zu saugenden Bodenbereichs dienen, unmittelbar eingeformt und/oder eingepreßt, eingespritzt oder eingeklebt. Vorzugsweise können diese Dichtelemente bei der Herstellung des Trägers vor dem Befüllen der Spritzgießform in diese eingelegt und beim Befüllen der Form umspritzt werden.Next are according to the invention in the bottom plate of the carrier Sealing or closing elements, on the one hand for retention a more or less precisely defined distance of the base plate from the floor to be sucked and at least to the other partially sealing boundary of the floor area to be vacuumed serve, directly molded and / or pressed, injected or glued in. These sealing elements can preferably be used in the manufacture of the carrier before filling the Injection mold placed in this and when filling the mold be encapsulated.
Durch die einstückige Gestaltung von Düsenträger und Bodenplatte, wobei zudem die wesentlichen Funktionseinheiten wie Strömungskanal, Saugkanal und den Strömungskanal umgebende Dicht- bzw. Abschlußelemente integraler Bestandteil des Trägers sind, wird die Zahl der separaten Bauteile entscheidend verringert, wodurch sich der Fertigungsaufwand und insbesondere der Montageaufwand in kostengünstiger Weise vermindert.Due to the one-piece design of the nozzle holder and base plate, the essential functional units such as Flow channel, suction channel and surrounding the flow channel Sealing and closing elements an integral part of the Are the number of separate components reduced, which reduces the manufacturing costs and in particular the assembly effort in a cost-effective manner reduced.
Um die Saugleistung der Staubsaugerdüse über die gesamte Breite der Düse zu verteilen, sind gemäß einem Ausführungsbeispiel der Erfindung die in den Saugkanal mündenden Strömungskanäle im wesentlichen parallel zur Vorder- und/oder Hinterkante des Trägers bzw. der Bodenplatte angeordnet und nach axial außen, bezogen auf die Längsachse der Strömungskanäle, offen. Um zudem die Saugleistung über die Länge der Kanäle möglichst gleichmäßig zu verteilen, sind die Strömungskanäle dabei vorzugsweise doppelparabolisch, d.h. sowohl im Querschnitt als auch im Längsschnitt, bezogen auf die Längsachse der Strömungskanäle, parabolisch ausgebildet, wobei im Querschnitt ein nach unten offenes Parabol-Profil mit zwei Parabelästen gebildet wird, während sich im Längsschnitt ein vom Saugkanal weg parabolisch verengendes Schnittprofil ergibt, wobei nur ein Parabelast, der im wesentlichen dem Grund der Strömungskanäle entspricht, vorhanden ist.To the suction power of the vacuum cleaner nozzle over the entire Distributing the width of the nozzle are according to one embodiment of the invention which opens into the suction channel Flow channels essentially parallel to the front and / or Arranged rear edge of the carrier or the base plate and axially outwards, based on the longitudinal axis of the Flow channels, open. To also the suction power over the The length of the channels should be distributed as evenly as possible Flow channels are preferably double parabolic, i.e. both in cross section and in longitudinal section, based on the longitudinal axis of the flow channels, parabolic, with a parabolic profile open at the bottom with two parabolic branches is formed while extending in longitudinal section a cutting profile parabolically narrowing away from the suction channel results, with only a parabolic load, which is essentially the Corresponds to the flow channels, is present.
Grundsätzlich kann die Staubsaugerdüse der Erfindung in an sich bekannter Weise als reine Gleitdüse, d.h. ohne Rollenelemente, ausgebildet sein. Insbesondere jedoch wenn der Träger und damit die Bodenplatte aus Kunststoff besteht, der gegenüber einer Metallausführung den Nachteil einer höheren Verschleißanfälligkeit aufweist, ist die Staubsaugerdüse im Bereich der Bodenplatte mit mindestens zwei vorderen Laufrollen versehen, die im Strömungskanal im Bereich der axial äußeren Enden so angeordnet sind, daß sie die Strömungskanäle nach außen im wesentlichen abschließen. Vorzugsweise ist jede der Laufrollen über zwei elastisch verformbare Achsschenkel im Strömungskanal gelagert, wobei jeder dieser Achsschenkel entweder im Boden des Strömungskanals einstückig angeformt oder dort befestigt, insbesondere nach Art einer Schnappverbindung verrastet ist. Aufgrund der elastischen Verformbarkeit der Achsschenkel weichen diese seitlich aus, wenn beispielsweise der Benutzer der Staubsaugerdüse von oben unbeabsichtigterweise auf den Träger tritt. Die Gefahr eines Bruches und damit einer Beschädigung der Rollenhalterung ist dadurch entscheidend vermindert. Vorzugsweise sind bei dieser Gestaltung die Durchmeser der Laufrollen zumindest geringfügig größer als die Tiefe der Strömungskanäle in diesem Bereich gewählt. Dadurch ergibt sich nach einer elastischen Verformung bzw. einem elastischen seitlichen Ausweichen der Achsschenkel bei einer unbeabsichtigten Belastung ein Form- und Kraftschluß direkt zwischen dem Boden der Strömungskanäle und damit dem Träger, den Laufrollen und dem Boden, wobei auch unter dieser Belastung die Bodenplatte und damit die besonders empfindlichen Kanten der Strömungskanäle einen ausreichenden Sicherheitsabstand vom Boden beibehalten, wodurch eine Beschädigung der Kanten zuverlässig verhindert wird.Basically, the vacuum cleaner nozzle of the invention can be found in known as a pure sliding nozzle, i.e. without roller elements, be trained. But especially if the Carrier and thus the base plate is made of plastic, the the disadvantage of a higher version compared to a metal version Has the susceptibility to wear, is the vacuum cleaner nozzle in the Area of the base plate with at least two front rollers provided in the flow channel in the area of the axial outer ends are arranged so that they flow channels essentially complete to the outside. Each is preferably the rollers on two elastically deformable steering knuckles in the Flow channel stored, each of these knuckles either integrally formed in the bottom of the flow channel or attached there, especially in the manner of a snap connection is locked. Because of the elastic deformability the steering knuckle dodge these sideways when for example, the user of the vacuum cleaner nozzle from above accidentally steps on the wearer. The danger of one Breakage and thus damage to the roll holder thereby significantly reduced. Preferably in this Design the diameter of the rollers at least slightly greater than the depth of the flow channels in this area chosen. This results in an elastic deformation or an elastic lateral deflection of the steering knuckle in the event of an unintended load, a positive and non-positive connection directly between the bottom of the flow channels and thus the Carrier, the rollers and the floor, also under this Loading the base plate and thus the particularly sensitive Edges of the flow channels a sufficient safety distance retained from the ground, causing damage the edges are reliably prevented.
Vorzugsweise sind die vorderen und/oder hinteren Kanten der Strömungskanäle, bezogen auf eine Richtung quer zu ihrer Längsachse, zumindest bereichsweise als Saug- bzw. Strömungsabrißkanten ausgebildet, um die Saugleistung der Düse zu erhöhen. Diese Saug- bzw. Strömungsabrißkanten können beispielsweise dadurch gebildet werden, daß die Kanten selbst wulstförmig aus der Ebene der Bodenplatte vorspringen. Vorzugsweise jedoch werden die Strömungsabrißkanten dadurch gebildet, daß der Flächenbereich vor der vorderen Strömungskanalkante und/oder der Flächenbereich hinter der hinteren Strömungskanalkante zumindest geringfügig gegenüber der Horizontalen bzw. der Ebene der Bodenplatte geneigt ist, wobei die Neigung so gewählt wird, daß die Strömungskanalkante ein zumindest geringfügig keilförmiges Profil erhält.The front and / or rear edges are preferably the Flow channels related to a direction transverse to their Longitudinal axis, at least in some areas as suction or flow separation edges trained to increase the suction power of the nozzle increase. These suction or flow separation edges can for example, be formed by the edges themselves Jump out from the level of the base plate in a bead shape. However, the flow separation edges are preferred formed that the surface area in front of the front flow channel edge and / or the area behind the rear Flow channel edge at least slightly compared to the Horizontal or the plane of the base plate is inclined, wherein the inclination is chosen so that the flow channel edge receives at least slightly wedge-shaped profile.
Zur Verbesserung der Reinigungseigenschaften der Staubsaugerdüse gemäß der Erfindung sind in an sich bekannter Weise streifen- oder bandförmige Fadenheber auf der Bodenplatte unmittelbar vor und/oder hinter dem Saugkanal angeordnet. Diese Fadenheber werden dabei entweder bei der Herstellung des Trägers unmittelbar eingeformt, insbesondere eingespritzt, oder auf den Träger oder in entsprechende vorgesehene Ausnehmungen des Trägers geklebt, gepreßt oder geschweißt.To improve the cleaning properties of the vacuum cleaner nozzle according to the invention are in a manner known per se strip or ribbon-shaped thread lifters on the base plate arranged immediately before and / or behind the suction channel. These thread lifters are used either in the manufacture of the Directly molded into the carrier, in particular injected, or provided on the carrier or in appropriate Recesses of the carrier glued, pressed or welded.
Die Staubsaugerdüse gemäß der Erfindung weist zum Anschluß des Saugrohres eines Staubsaugers einen Saugrohranschlußstutzen auf. Dabei kann dieser Saugrohranschlußstutzen ebenfalls einstückig an den Träger im Bereich des Saugkanals angeformt werden, wodurch sich eine weitere Reduzierung der Teile ergibt. Vorzugsweise jedoch ist der Saugrohranschlußstutzen als Gelenkstutzen ausgeführt, der mit seinem ersten Ende am Ausgang des Saugkanals und mit seinem zweiten Ende am Saugrohr eines Staubsaugers befestigbar, insbesondere nach Art einer Schnappverbindung lösbar verrastbar ist.The vacuum cleaner nozzle according to the invention has for connecting the Suction pipe of a vacuum cleaner a suction pipe connection piece on. This intake manifold connection piece can also integrally formed on the carrier in the area of the suction channel be, which results in a further reduction in parts results. However, the intake manifold connecting piece is preferred designed as an articulated socket with its first end on Exit of the suction channel and with its second end on the suction pipe attachable to a vacuum cleaner, especially in the manner of a Snap connection is releasably lockable.
Die Dicht- bzw. Abschlußelemente, die die Strömungskanäle zumindest bereichsweise mit Abstand umgeben, bestehen vorzugsweise in Abhängigkeit vom gewünschten Verwendungszweck aus einem Borstenkranz und/oder aus Dichtlippen, insbesondere aus Dichtlippen aus einem Elastomermaterial. Dabei werden Dichtlippen insbesondere bei der geplanten Verwendung der Düse für glatte Böden bzw. zum Naßsaugen verwendet.The sealing or closing elements, the flow channels Surrounded at least in certain areas, preferably exist depending on the intended use a bristle ring and / or from sealing lips, in particular from Sealing lips made of an elastomer material. Thereby sealing lips especially with the planned use of the nozzle for smooth floors or used for wet vacuuming.
Um die Handhabbarkeit der Staubsaugerdüse weiter zu verbessern, kann nach einem weiteren Ausführungsbeispiel der Erfindung im Bereich des saugrohrseitigen Endes des Saugkanals am Träger mindestens eine hintere Laufrolle angeordnet sein. Dabei kann diese hintere Laufrolle als einzige Laufrolle oder in Verbindung mit den vorstehend beschriebenen vorderen Laufrollen Verwendung finden.To further improve the manageability of the vacuum cleaner nozzle, can according to a further embodiment of the Invention in the area of the suction pipe-side end of the suction channel at least one rear roller can be arranged on the carrier. This rear roller can be the only roller or in conjunction with the front casters described above Find use.

- 1 in cross section along the section line AA of FIG. 2nd
In Fig. 1 ist in perspektivischer Ansicht ein Ausführungsbeispiel
einer erfindungsgemäßen Staubsaugerdüse gezeigt. Die
Staubsaugerdüse weist dabei einen Düsenkörper 1 auf, an den
eine Bodenplatte 2 einstückig angeformt ist, wodurch insgesamt
ein einstückiger Träger gebildet wird. In den Träger eingeformt
sind dabei Strömungskanäle 3 und 4 sowie ein Saugkanal
5. Der Saugkanal ist im wesentlichen zentral, bezogen auf die
Breite der Düse, angeordnet und mündet einerseits in die
Strömungskanäle 3 und 4 und andererseits in einen Saugrohranschlußstutzen
6, der als Gelenkstutzen ausgeführt ist.In Fig. 1 is an embodiment in perspective view
shown a vacuum cleaner nozzle according to the invention. The
The vacuum cleaner nozzle has a
Wie insbesondere der Darstellung nach Fig. 3 zu entnehmen ist,
besteht der Saugrohranschlußstutzen aus einem düsenseitigen
Gelenkteil 7, das in einer entsprechend gestalteten zum Saugkanal
5 führenden Öffnung des Trägers gelenkig so verrastet
ist, daß das Gelenkteil 7 um die Achse 8 verschwenkbar ist,
und einem saugrohrseitigen Gelenkteil 9, das am Gelenkteil 7
drehbar angelenkt ist.As can be seen in particular from the illustration according to FIG. 3,
the intake manifold connection piece consists of a nozzle-side
Hinge
Im Bereich des saugrohrseitigen Endes des Saugkanals 5 sind am
Träger zwei hintere Laufrollen 10 auf einer gemeinsamen Achse
angeordnet, um die Handhabbarkeit der Staubsaugerdüse zu
verbessern. In the area of the suction pipe-side end of the
In Fig. 2 ist die Staubsaugerdüse gemäß Fig. 1 in Ansicht von
unten dargestellt. Dabei ist der Darstellung zu entnehmen, daß
die Strömungskanäle 3 und 4 im wesentlichen parallel zur
Vorder- bzw. Hinterkante der Bodenplatte, d.h. senkrecht zur
Schnittlinie A-A verlaufen. Dabei sind die Strömungskanäle 3
und 4 nach axial außen offen ausgebildet, wobei im jeweils
axial äußersten Bereich je eine vordere Laufrolle 11 angeordnet
ist. Im axial inneren Bereich münden beide Strömungskanäle
in den Saugkanal 5. Jede Laufrolle 11 ist dabei auf zwei Achsschenkeln
12 gelagert, die in entsprechende Ausnehmungen im
Grund der Strömungskanäle 3 und 4 eingerastet sind. Die Achsschenkel
12 sind dabei aus einem elastisch nachgiebigen
Material. Der Durchmesser, d.h. genauer der maximale Mitteldurchmesser
der Laufrollen 11 ist dabei zumindest geringfügig
größer gewählt als die Tiefe der Strömungskanäle 3 und 4 in
diesem Bereich. Dies bedeutet mit anderen Worten, daß, wenn
der Bediener der Staubsaugerdüse unbeabsichtigt von oben auf
den Träger tritt, die Achsschenkel 12 seitwärts ausweichen,
bis die Laufrollen 12 auf dem Grund der Strömungskanäle 3 und
4 zur Anlage kommen. Dadurch ergibt sich ein Kraftschluß
zwischen dem Grund der Strömungskanäle, der Laufrolle und dem
Boden, wobei unter allen Umständen ein Sicherheitsabstand
zwischen dem Boden der Gleitsohle bzw. der Unterfläche der
Bodenplatte 2 und dem Boden verbleibt. Dadurch wird eine
Beschädigung der Kanten der Strömungskanäle 3 und 4 zuverlässig
ausgeschlossen.In Fig. 2, the vacuum cleaner nozzle according to FIG. 1 is in view of
shown below. It can be seen from the illustration that
the
Wie ebenfalls aus der Darstellung nach Fig. 2 zu ersehen ist,
sind in der Bodenplatte 2 Dicht- bzw. Abschlußelemente in Form
von Elastomerdichtlippen 13 und 14 angeordnet. Die Dichtlippen
13,14 erstrecken sich dabei im wesentlichen über die gesamte
Breite der Staubsaugerdüse und schließen zwischen sich mit
Abstand die Strömungskanäle 3 und 4 ein. Wie aus der
Darstellung nach Fig. 3 ersichtlich, sind die Dichtlippen als
separat vorgefertigte Dichtleisten in entsprechende nutartige
Ausnehmungen 15 und 16 der Bodenplatte 2 eingelegt und dort
durch Ultraschallschweißen oder Verkleben befestigt. As can also be seen from the illustration in FIG. 2,
are in the
Zur Verbesserung der Reinigungswirkung der Staubsaugerdüse
sind im Bodenbereich der Bodenplatte 2 vor und hinter der
Öffnung des Saugkanals 5 je ein Fadenheberstreifen 17 und 18
angeordnet. Diese Fadenheberstreifen 17 und 18 bestehen dabei
in an sich bekannter Weise aus einem florartigen Textilmaterial,
dessen Flor jeweils in Richtung der Öffnung des
Saugkanals 5 weist. Die Fadenheber sind bei dem gezeigten Ausführungsbeispiel
in Vertiefungen der Bodenplatte 2 eingeklebt.To improve the cleaning effect of the vacuum cleaner nozzle
are in the bottom area of the
Die Strömungskanäle 3 und 4 weisen beim gezeigten Ausführungsbeispiel
ein doppelparabolisches Profil auf. Dabei ist, wie
der Darstellung nach Fig. 3 zu entnehmen ist, der Strömungskanal
4 (dies gilt in identischer Weise auch für den
Strömungskanal 3) im Querschnitt dergestalt parabelförmig
ausgebildet, daß der Grund des Strömungskanals 4 den Scheitel
der Parabel und die nach unten zur Bodenplatte weisenden Wandbereiche
die Parabeläste bilden. In ähnlicher Weise definiert
der Längsschnitt durch den Strömungskanal 4 in einer Ebene,
die im wesentlichen senkrecht zur Ebene der Bodenplatte 2
verläuft und durch den Scheitel bzw. Grund des Strömungskanals
4 verläuft, ein parabelförmiges von axial außen sich in
Richtung zum Saugkanal 5 aufweitendes Profil, wobei jedoch bei
diesem Ausführungsbeispiel durch den Grund des Strömungskanals
4 lediglich ein Parabelast verwirklicht ist, da der Strömungskanal
4 diametral gegenüber, d.h. nach unten, offen ist.The
Die Vorderkanten 19 und die Hinterkanten 20 der Strömungskanäle
3 und 4 sind als Strömungsabriß- oder Strömungsleitkanten
ausgebildet. Dazu sind die hinter den Kanten 20
liegenden Flächenbereiche der Bodenplatte 2 und die vor den
Kanten 19 liegenden Flächenbereiche der Bodenplatte 2 in aus
den Figuren nicht ersichtlicher Weise um einige wenige Winkelgrade
gegenüber der Bodenplattenebene oder Horizontalebene von
den Kanten 19 und 20 weg nach oben geneigt, wodurch sich eine
schwach keilförmige Strömungsabrißkantenform ergibt.The front edges 19 and the
