Abstract

The vacuum cleaner nozzle has thread pickups which are arranged on both sides of the suction channel, bounded by mouthpiece edges, with their longitudinal axes parallel to the suction channel and they consist of oblique bristle material attached to a bearing plate. In order to maintain the full effect of the thread pickups when vacuum cleaning various types of carpets, provision is made for the thread pickups (6 and 7) themselves or in relation to one another to be set back at different depths in relation to the relevant mouthpiece edge (4 or 5). <IMAGE>

Description

Die Erfindung bezieht sich auf eine Staubsaugerdüse, bei der zu beiden Seiten des durch Mundstückkanten begrenzten Saugkanals aus auf einer Tragplatte befestigtem Schrägborstenstoff bestehende Fadenheber mit ihrer Längsachse parallel zu dem Saugkanal angeordnet sind.The invention relates to a vacuum cleaner nozzle, in which on both sides of the suction channel delimited by the edges of the mouthpiece, thread levers consisting of inclined bristle material attached to a support plate are arranged with their longitudinal axis parallel to the suction channel.

Eine solche Staubsaugerdüse ist durch die DE-PS 15 03 830 bekannt. Bei dieser Düse sind die Fadenheber flach ausgebildet und in einer Ebene angeordnet. Mit einer Staubsaugerdüse müssen verschiedene Teppicharten und zwar solche mit weicherem oder härterem Flor bearbeitet werden. Je nach Festigkeit des Flors ergeben sich verschie- -. dene Eindringtiefen der Düse. Beim Absaugen eines Teppichs mit weichem Flor liegen bei der bekannten Düse infolge des tieferen Einsinkens der Düse in den Flor die Fadenheber fest auf dem Flor auf. Hierdurch werden die schrägstehenden Borsten des Schrägborstenstoffes vollkommen angedrückt, so daß sie ihre Funktion nicht mehr erfüllen können. Außerdem ergibt sich durch das feste Anliegen ein erhöhter Strömungswiderstand, der einen Luftstrom unter den Fadenheber hindurch erschwert bzw. ganz verhindert.Such a vacuum cleaner nozzle is known from DE-PS 15 03 830. In this nozzle, the thread lifters are flat and arranged in one plane. With a vacuum cleaner nozzle, different types of carpets must be processed, namely those with a softer or harder pile. Depending on the strength of the pile, different -. penetration depths of the nozzle. When vacuuming a carpet with a soft pile, the thread lifters in the known nozzle lie firmly on the pile as a result of the nozzle sinking deeper into the pile. As a result, the inclined bristles of the inclined bristle material are completely pressed so that they can no longer fulfill their function. It also results from the fixed There is an increased flow resistance, which impedes or completely prevents an air flow under the thread lifter.

Der Erfindung liegt die Aufgabe zugrunde, eine Staubsaugerdüse so auszubilden, daß die Wirkung des Fadenhebers beim Absaugen verschiedener Teppicharten erhalten bleibt und eine Erhöhung des Strömungswiderstandes am Fadenheber weitgehend vermieden ist.The invention has for its object to design a vacuum cleaner nozzle so that the effect of the thread lifter is maintained when vacuuming different types of carpets and an increase in flow resistance at the thread lifter is largely avoided.

Die Lösung der gestellten Aufgabe gelingt nach der Erfindung dadurch, daß die Fadenheber in sich oder in bezug zueinander gegenüber der betreffenden Mundstückkante verschieden tief zurückgesetzt sind. Auf diese Weise wird erreicht, daß beim Absaugen eines Teppichs mit festem oder weichem Flor der eine oder andere Fadenheber bzw. Teile der Fadenheber wirksam sind.The object is achieved according to the invention in that the thread lifters in themselves or in relation to each other are set to different depths relative to the relevant mouthpiece edge. In this way it is achieved that one or the other thread lifter or parts of the thread lifter are effective when vacuuming a carpet with a firm or soft pile.

Eine unterschiedlich tiefe Anordnung der Fadenheber gegenüber der Mundstückkante wird auf einfache Weise dadurch erreicht, daß die Fadenheber unterschiedlich dicke Tragplatten aufweisen.A different depth arrangement of the thread lifters with respect to the edge of the mouthpiece is easily achieved in that the thread lifters have support plates of different thicknesses.

Dadurch, daß die Fadenheber um ihre Längsachse gewölbt ausgebildet sind, ist der Fadenheber in sich verschieden tief gegenüber der Mundstückkante zurückgesetzt. Damit bleiben bei verschiedenem starken Einsinken der Staubsaugerdüse in den Teppichflor immer noch Teile des Fadenhebers voll wirksam.Because the thread lifters are curved around their longitudinal axis, the thread lifter is set back at different depths in relation to the edge of the mouthpiece. This means that parts of the thread lifter remain fully effective if the vacuum cleaner nozzle sinks into the carpet pile to varying degrees.

Eine Wölbung des Fadenhebers wird dadurch erreicht, daß die Tragplatte für den Schrägborstenstoff gewölbt ausgebildet ist oder auch dadurch, daß der Fadenheber eine flache Tragplatte aufweist, die mit ihren beiden Längsseiten in zwei entsprechende, an der Unterseite der Staubsaugerdüse vorgesehene Längsschlitze eingesteckt ist, deren Abstand zueinander kleiner als die Breite des Fadenhebers ist. Im letzten Fall wird die Wölbung des Fadenhebers durch das Einstecken in die Längsschlitze erreicht.A curvature of the thread lifter is achieved in that the support plate for the inclined bristle material is arched or in that the thread lifter has a flat support plate which, with its two longitudinal sides, is inserted into two corresponding longitudinal slots provided on the underside of the vacuum cleaner nozzle is stuck, the distance from each other is smaller than the width of the thread lifter. In the latter case, the thread lifter is arched by inserting it into the longitudinal slots.

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

  • Fig. 1 eine Staubsaugerdüse, bei der die Fadenheber zueinander verschieden tief gegenüber der Mundstückkante zurückgesetzt sind;
  • Fig. 2 eine Staubsaugerdüse, bei der die Fadenheber um ihre Längsachse gewölbt ausgebildet sind;
  • Fig. 3 einen Fadenheber mit gewölbter Tragplatte und
  • Fig. 4 einen Fadenheber mit flacher Tragplatte, bei dem die Wölbung durch das Einstecken in Längsschlitze erzielt wird.
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 nozzle in which the thread lifters are set back to one another at different depths from the edge of the mouthpiece;
  • Fig. 2 is a vacuum cleaner nozzle in which the thread lifters are curved around their longitudinal axis;
  • Fig. 3 is a thread lifter with a curved support plate and
  • Fig. 4 is a thread lifter with a flat support plate, in which the curvature is achieved by inserting into longitudinal slots.

Die in Fig. 1 dargestellte Staubsaugerdüse 1 weist einen Sauganschluß 2 auf, der mit einem an der Unterseite der Staubsaugerdüse 1 vorgesehenen Saugkanal 3 in Saugverbindung steht. Der Saugkanal 3 wird zu beiden Seiten von Mundstückkanten 4 und 5 begrenzt. Parallel zu dem Saugkanal 3 sind Fadenheber 6 und 7 angeordnet. Der in Arbeitsrichtung vor dem Saugkanal 3 angeordnete Fadenheber 6 ist gegenüber der Mundstückkante 4 um das Maß a und der hinter dem Saugkanal 3 angeordnete Fadenheber 7 um das Maß b zurückgesetzt. Das Maß b ist kleiner als das Maß a. Dieser unterschiedlich tiefe Versatz der Fadenheber 6 und 7 gegenüber den Mundstückkanten 4 und 5 wird durch unterschiedlich dicke Tragplatten 8 und 9 erreicht. Die Tragplatte 9 ist hierbei dicker ausgebildet als die Tragplatte 8.The vacuum cleaner nozzle 1 shown in FIG. 1 has a suction connection 2, which is in suction connection with a suction channel 3 provided on the underside of the vacuum cleaner nozzle 1. The suction channel 3 is delimited on both sides by mouthpiece edges 4 and 5. Thread lifters 6 and 7 are arranged parallel to the suction channel 3. The thread lifter 6 arranged in front of the suction channel 3 in the working direction is set back by the dimension a and the thread lifter 7 arranged behind the suction channel 3 by the dimension b. The dimension b is smaller than the dimension a. This differently deep offset of the thread lifters 6 and 7 with respect to the mouthpiece edges 4 and 5 is achieved by supporting plates 8 and 9 of different thicknesses. The support plate 9 is made thicker than the support plate 8.

Wird mit einer solchen Staubsaugerdüse ein Teppich mit hartem Flor abgesaugt, so sinken die Mundstückkahten 4 und 5 nur wenig in den Teppichflor ein, so daß der hinter dem Saugkanal 3 angeordnete Fadenheber 7 intensiver als der vor dem Saugkanal 3 angeordnete Fadenheber 6 zur Wirkung kommt. Beim Absaugen eines Teppichs mit weichem Flor sinken die Mundstückkanten 4 und 5 tiefer in den Flor ein, wodurch dann die Schrägborsten des hinter dem Saugkanal 3 angeordneten Fadenhebers 7 an die Tragplatte 9 angedrückt werden können, so daß dieser Fadenheber seine Funktion nicht mehr voll erfüllen kann. Dafür kommt jedoch der vor dem Saugkanal 3 angeordnete Fadenheber 6 besser zur Wirkung, da er gegenüber der Mundstückkante 4 so weit zurückgesetzt ist, daß seine Schrägborsten auch bei einem tieferen Einsinken der Mundstückkanten 4 und 5 in ihrer Wirkung nicht beeinträchtigt werden.If a carpet with a hard pile is suctioned off with such a vacuum cleaner nozzle, the mouthpiece seams 4 and 5 sink only a little into the carpet pile, so that the thread lifter 7 arranged behind the suction channel 3 has a more intensive effect than the thread lifter 6 arranged in front of the suction channel 3. When vacuuming a carpet with a soft pile, the mouthpiece edges 4 and 5 sink deeper into the pile, as a result of which the inclined bristles of the thread lifter 7 arranged behind the suction channel 3 can be pressed onto the support plate 9, so that this thread lifter can no longer fully fulfill its function . For this, however, the thread lifter 6 arranged in front of the suction channel 3 has a better effect since it is set back so far relative to the mouthpiece edge 4 that its inclined bristles are not impaired in their action even when the mouthpiece edges 4 and 5 sink in deeper.

Bei der in Fig. 2 dargestellten Staubsaugerdüse 1 sind die Fadenheber 6 und 7 an ihrer Oberfläche gewölbt ausgeführt. Durch diese Wölbung sind die Fadenheber 6 und 7 in sich verschieden tief gegenüber den Mundstückkanten 4 und 5 zurückgesetzt. Damit bleibt je nach Einsinktiefe der Mundstückkanten 4 und 5 in den Teppichflor immer ein Teilbereich der Fadenheber 6 und 7 voll wirksam. Durch die gewölbte Form der Fadenheber 6 und 7 ergibt sich nur eine geringe Auflagefläche der Fadenheber, so daß insbesondere bei dieser Form der Strömungswiderstand sehr gering bleibt und damit stets ein Luftstrom unter den Fadenhebern hindurch möglich ist. Die Wölbung der Fadenheber 6 und 7 kann dadurch erreicht werden, daß - wie in Fig. 3 dargestellt - eine gewölbte Tragplatte 10 vorgesehen ist, auf deren Wölbung der Schrägborstenstoff 11 befestigt ist. Es besteht aber auch die Möglichkeit, eine flache Tragplatte 12 vorzusehen und diese mit ihren Längsseiten in Längsschlitze 13 einzustecken, deren Abstand kleiner ist als die Breite der Tragplatte 12. Durch eine solche geometrische Ausbildung wird die Tragplatte 12 beim Einstecken in die Längsschlitze 13 zwangsläufig gewölbt. Um den Fadenheber sicher in den Längsschlitzen 13 zu halten, sind an den äußeren Längskanten dieser Längsschlitze 13 sägezahnartige Zacken vorgesehen, die mit ihren Spitzen in den Fadenheber eingreifen.In the vacuum cleaner nozzle 1 shown in FIG. 2, the thread lifters 6 and 7 are curved on their surface. This curvature means that the thread lifters 6 and 7 are set back at different depths in relation to the mouthpiece edges 4 and 5. Depending on the sinking depth of the mouthpiece edges 4 and 5 into the carpet pile, a partial area of the thread lifters 6 and 7 always remains fully effective. Due to the curved shape of the thread lifters 6 and 7, there is only a small contact surface of the thread lifters, so that the flow resistance remains very low, in particular with this shape, and an air flow under the thread lifters is therefore always possible. The curvature of the thread lifters 6 and 7 can be achieved in that - as shown in FIG. 3 - an arched support plate 10 is provided, on the curvature of which the oblique bristle material 11 is fastened. But there is also the possibility to provide a flat support plate 12 and this with its long sides in Insert longitudinal slots 13, the spacing of which is smaller than the width of the support plate 12. Such a geometric configuration inevitably causes the support plate 12 to be arched when it is inserted into the longitudinal slots 13. In order to hold the thread lifter securely in the longitudinal slots 13, sawtooth-like teeth are provided on the outer longitudinal edges of these longitudinal slots 13 and engage with their tips in the thread lifter.
