Abstract

Es handelt sich um eine Staubsaugerduse (1), welche mit einer Sperreinrichtung zwischen Anschlußstutzen (3) und Düsengehäuse (2) versehen ist, die beide in einem gewissen Schwenkbereich derart miteinander verriegelt, daß beide gemeinsam eine synchrone Schwenkbewegung durchführen. Die Verriegelung kann nach Überwinden eines gefederten Sperrbolzens (7) aufgehoben werden.It is a vacuum cleaner nozzle (1), which is provided with a locking device between the connecting piece (3) and the nozzle housing (2), both of which are locked together in a certain swivel range in such a way that the two together perform a synchronous swivel movement. The lock can be released after overcoming a spring-loaded locking bolt (7).

Description

Die Erfindung betrifft eine Staubsaugerdüse mit einem Anschlußstutzen, welcher im Düsengehäuse verschwenkbar gelagert ist.The invention relates to a vacuum cleaner nozzle with a connecting piece which is pivotally mounted in the nozzle housing.

Derartige Staubsaugerdüsen gehören zum Stand der Technik. Ein verschwenkbarer Anschlußstutzen ist notwendig, um bei der Hin- und Herbewegung des Staubsaugers beim Saugen die Bodenplatte der Staubsaugerdüse parallel auf dem Untergrund zu halten. Des weiteren muß auch unter niedrigen Möbel teil en gesaugt werden können. Dazu muß der angeschlossene Handstaubsauger oder das Saugrohr eines Bodenstaubsaugers extrem flach gelegt werden. Dies wäre ohne schwenkbaren Anschlußstutzen nicht möglich.Such vacuum cleaner nozzles belong to the prior art. A pivotable connection piece is necessary in order to keep the base plate of the vacuum cleaner nozzle parallel to the surface when the vacuum cleaner is being moved back and forth. Furthermore, parts must be able to be sucked under low furniture. To do this, the connected handheld vacuum cleaner or the suction pipe of a cylinder vacuum cleaner must be laid extremely flat. This would not be possible without a swiveling connecting piece.

Da alle diese Staubsaugerdüsen mit ihrer Bodenplatte dicht am Untergrund anliegen, um in den in der Bodenplatte üblichen Kanälen eine hohe Luftgeschwindigkeit zu erzeugen und somit das Saugergebnis günstig zu beeinflussen, ergeben sich jedoch Schwierigkeiten beim Aufsaugen von groben Schmutzteil en, die aufgrund ihrer Abmessungen nicht mehr durch die Saugkanäle gesaugt werden können.Since all of these vacuum cleaner nozzles lie close to the surface with their base plate in order to generate a high air speed in the channels customary in the base plate and thus have a favorable influence on the suction result, difficulties arise when vacuuming up coarse dirt particles, which due to their dimensions no longer exist can be sucked through the suction channels.

Dazu muß die Staubsaugerdüse mit ihrer Bodenplatte vom Untergrund abgehoben werden, um so den groben Schmutztellen einen ungehinderten Zugang zur meist in der Mitte angeordneten zentralen Saugöffnung zu ermöglichen. Dies ist noch einfach beim Hantieren mit dem Saugrohr eines Bodenstaubsaugers, wird jedoch mühsam bei einem angeschlossenen Handstaubsauger. Hier muß der Benutzer das gesamte Gewicht des Handstaubsaugers hochheben, um die Staubsaugerdüse mit ihrer Bodenplatte vom Untergrund abzuheben.For this purpose, the vacuum cleaner nozzle with its base plate has to be lifted off the surface, so that the coarse dirt spots have unhindered access to the central suction opening, which is usually arranged in the middle. This is still easy when handling the suction tube of a cylinder vacuum cleaner, but it becomes tedious when a handheld vacuum cleaner is connected. Here the user has to lift the entire weight of the handheld vacuum cleaner in order to lift the vacuum cleaner nozzle with its base plate off the ground.

Aufgabe der Erfindung ist nun, eine Einrichtung an einer Staubsaugerdüse zu schaffen, welche es ermöglicht, grobe Schmutzteile aufzusaugen, ohne die Staubsaugerdüse vom Untergrund mitsamt Staubsauger abheben zu müssen.The object of the invention is now to provide a device on a vacuum cleaner nozzle which makes it possible to vacuum up coarse dirt particles without having to lift the vacuum cleaner nozzle together with the vacuum cleaner.

Erfindungsgemäß wird die Aufgabe durch die Merkmale des Anspruchs 1 gelöst.According to the invention the object is achieved by the features of claim 1.

Somit hat die Erfindung zum Vorteil, daß Staubsaugerdüsen mit einer Einrichtung versehen werden können, welche es ermöglicht, grobe Schmutzteile aufzusaugen, ohne daß ein angeschlossener Staubsauger unter Kraftaufwand hochgehoben werden muß.The invention thus has the advantage that vacuum cleaner nozzles can be provided with a device which makes it possible to vacuum up coarse dirt particles without a connected vacuum cleaner having to be lifted up with great effort.

Anhand der nachfolgenden Beschreibung ist ein Ausführungsbeispiel gezeichnet und beschriedben.On the basis of the following description, an exemplary embodiment is drawn and described.

Es zeigt:

  • Fig. 1 Eine Staubsaugerdüse im entriegelten Zustand mit einem Teil schnitt,
  • Fig. 2 eine Seitenansicht zu Fig. 1 mit Teil schnitt,
  • Fig. 3 eine Staubsaugerdüse im verriegelten Zustand mit einem Teilschnitt,
  • Fig. 4 eine Seitenansicht zu Fig. 3 mit Teilschnitt.
It shows:
  • 1 A vacuum cleaner nozzle in the unlocked state with a part cut,
  • 2 is a side view of FIG. 1 with part section,
  • 3 is a vacuum cleaner nozzle in the locked state with a partial section,
  • Fig. 4 is a side view of Fig. 3 with partial section.

In Fig. 1 ist eine Staubsaugerdüse 1 dargestellt, welche einen im Düsengehäuse 2 verschwenkbar angeordneten Anschl ußstutzen 3 aufweist. Unten am Düsengehäuse 2 ist eine Bodenplatte 4 angeordnet ( siehe Fig. 2).In Fig. 1, a vacuum cleaner nozzle 1 is shown, which has a connection piece 3 pivotably arranged in the nozzle housing 2. A bottom plate 4 is arranged at the bottom of the nozzle housing 2 (see FIG. 2).

Aus den Figuren 1 und 2 ist zu erkennen, daß am Anschl ußstutzen 3 eine Anlauffläche 5 und ein vertiefter Absatz 6 angeordnet ist, welcher je nach Winkel der Schwenkbewegung des Ansaugstutzens 3 in den Bereich eines beweglich im Düsengehäuse 2 gelagerten Bolzens 7 gerät.From Figures 1 and 2 it can be seen that a contact surface 5 and a recessed shoulder 6 is arranged on the connecting piece 3, which, depending on the angle of the pivoting movement of the suction piece 3, comes into the region of a bolt 7 movably mounted in the nozzle housing 2.

Der Bolzen 7 liegt in einer Führungshülse 8 und besitzt eine Druckfeder 9.The bolt 7 lies in a guide sleeve 8 and has a compression spring 9.

In den Fig. 1 und 2 liegt dieser Bolzen 7 gegen die Anlauffläche 5 an, und der Ansaugstutzen 3 kann beinahe in seinem gesamten Schwenkbereich verschwenkt werden, bis er in die Stellung in Fig. 3 und 4 gebracht wird.1 and 2, this bolt 7 bears against the contact surface 5, and the intake manifold 3 can be pivoted almost in its entire pivoting range until it is brought into the position in FIGS. 3 and 4.

Hier gerät der Bolzen 7 in den Bereich des Absatzes 6; und die Druckfeder 9 drückt ihn in diesen Absatz 6 hinein. Somit sind Düsengehäuse 2 und Anschlußstutzen 3 so miteinander verriegelt, daß beim Herunterschwenken des Anschlußstutzens 3 das Düsengehäuse 2 so mitverschwenkt, daß sich die Vorderkante 10 des Düsengehäuses 2 im gleichen Maße anhebt, wie der Anschlußstutzen 3 verschwenkt. Somit können grobe Schmutzteile aufgesaugt werden.Here the bolt 7 comes into the area of paragraph 6; and the compression spring 9 presses it into this paragraph 6. Thus, the nozzle housing 2 and connecting piece 3 are locked together so that when the connecting piece 3 is pivoted down, the nozzle housing 2 is also pivoted in such a way that the front edge 10 of the nozzle housing 2 rises to the same extent as the connecting piece 3 pivots. Coarse dirt can thus be vacuumed up.

Um wieder die Entriegelung für den normalen Gebrauch herzustellen, muß der Benutzer z.B. mit Hilfe seines Fußes eine Kraft auf das Düsengehäuse 2 aufbringen und gleichzeitig den Anschlußstutzen 3 nach unten verschwenken. Durch die konische Ausbildung der Bolzenspitze 11 rutscht dann der Bolzen 7 gegen die Kraft der Druckfeder 9 über den Absatz 6 zurück auf die Anlauffläche 5 und eine "normale" Benutzung ist wieder möglich.In order to restore the release for normal use again, the user must e.g. apply a force to the nozzle housing 2 with the help of his foot and at the same time pivot the connection piece 3 downwards. Due to the conical design of the pin tip 11, the pin 7 then slips back against the force of the compression spring 9 via the shoulder 6 onto the contact surface 5 and "normal" use is possible again.
