Abstract

The invention relates to a plug coupling for the pivotable connection nozzle of vacuum cleaner accessories for connection to the suction nozzle of the vacuum cleaner. This takes place by a locking knob in the connection nozzle which projects into a locking opening in the suction nozzle. The locking knob is actuated by a pushbutton which, when the connection is pivoted, automatically moves into the vertical plane and slightly beyond against a run-up surface and is thus pressed in. The connection can be released by this means. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Steckkupplung für den schwenkbaren Anschlußstutzen von Staubsaugerzubehörteilen zum Verbinden mit dem Saugstutzen des Staubsaugers, wobei die Verriegelung zwischen Anschlußstutzen und Saugstutzen durch ein Verriegelungsteil und die Betätigung des Verriegelungsteils durch eine vom Verriegelungsteil entfernt angeordnete Drucktaste erfolgt.The invention relates to a plug-in coupling for the pivotable connection piece of vacuum cleaner accessories for connection to the suction port of the vacuum cleaner, the locking between the connection piece and suction port being effected by a locking part and the actuation of the locking part by a push button arranged away from the locking part.

Solche Verriegelungen sind aus der DE-PS 1 450 445 bekannt. Hierbei ist am Anschlußstutzen des Staubsaugerzubehörteils eine Art Hakenfalle vorgesehen, welche über einen Hebel mit einer entfernt liegenden Drucktaste verbunden ist.Such locks are known from DE-PS 1 450 445. Here, a type of hook trap is provided on the connecting piece of the vacuum cleaner accessory, which is connected via a lever to a remote push button.

Nachteilig bei dieser Anordnung ist für den Benutzer, daß er sich beim Lösen der Verbindung tief bücken muß, um die Drucktaste zu erreichen. Dabei muß er dann auch noch gleichzeitig an der anderen Verbindungsseite ziehen, um die Verbindung zu lösen.A disadvantage of this arrangement for the user is that he has to bend down deeply when disconnecting in order to reach the pushbutton. He must then pull the other side of the connection at the same time to release the connection.

Die Erfindung hat nun zur Aufgabe, unter Vermeidung der im Stand der Technik vorhandenen Benutzungsnachteile eine Verbindung zu schaffen, welche auf einfache Art und Weise lediglich durch eine Bewegung der Verbindung selbst gelöst werden kann.The object of the invention is to create a connection which avoids the disadvantages of use which are present in the prior art and which can be solved in a simple manner only by moving the connection itself.

Erfindungsgemäß wird die Aufgabe durch die Merkmale des Anspruchs 1 gelöst. Des weiteren zeigen die Ansprüche 2 und 3 Ausgestaltungen der Erfindung. Dadurch, daß eine elastische Haltenase am Anschlußstutzen angeordnet ist, ist es weiterhin möglich, einen Staubsauger mitsamt Staubsaugerzubehörteil aufzuhängen, ohne daß die Verbindung unbeabsichtigt gelöst wird.According to the invention the object is achieved by the features of claim 1. Furthermore, claims 2 and 3 show embodiments of the invention. Characterized in that an elastic retaining lug is arranged on the connecting piece, it is also possible to hang up a vacuum cleaner together with the vacuum cleaner accessory part without the connection being unintentionally released.

Somit hat die Erfindung zum Vorteil, daß der Benutzer die Verbindung zwischen Staubsauger und Staubsaugerzubehörteil bzw. Saugrohr und Zubehörteil auf einfache Weise durch Verschwenken lösen kann, ohne sich bücken zu müssen.The invention thus has the advantage that the user can easily disconnect the connection between the vacuum cleaner and the vacuum cleaner accessory part or the suction pipe and accessory part by pivoting without having to bend down.

Nachstehend ist ein Ausführungsbeispiel der Erfindung gezeichnet und beschrieben.An exemplary embodiment of the invention is drawn and described below.

Die Fig. 1 zeigt das Arbeiten mit einem sogenannten Stiel- oder Handstaubsauger (1), an welchem ein Staubsaugerzubehörteil (2) angeordnet ist. Solch ein Staubsaugerzubehörteil (2) ist mit seinem Anschlußstutzen (3) am Saugstutzen (4) des Stiel- oder Handstaubsaugers (1) befestigt. In der Vergrößerung ist dieser Bereich deutlicher dargestellt.
Im üblichen Fall muß nun der Benutzer, wenn er das Staubsaugerzubehörteil (2) wechseln will, auf die Drucktaste (5) drücken, um das Staubsaugerzubehörteil (2) vom Stiel- oder Handstaubsauger (1) zu lösen.
Dazu muß er sich bücken. Gemäß der Erfindung ist aber im Bereich der Drucktaste (5) an dem Staubsaugerzubehörteil (2) eine Anlauffläche (6) angeordnet. Wenn nun der Benutzer gemäß Fig. 2 den Stiel- oder Handstaubsauger (1) senkrecht stellt und ihn noch ein wenig nach vorn drückt, so gelangt die Drucktaste (5) gegen die Anlauffläche (6) an dem Staubsaugerzubehörteil (2) zur Anlage und wird eingedrückt, so daß die Verbindung entriegelt und Anschlußstutzen (3) und Saugstutzen (4) voneinander gelöst werden können. Dies geschieht durch Ziehen in Pfeilrichtung, wobei das Staubsaugerzubehörteil durch den Fuß des Benutzers kurz belastet wird.
Der Ablauf dieser Entriegelung und der Aufbau der Mechanik ist im einzelnen in den Figuren 3 - 5 dargestellt.Fig. 1 shows the work with a so-called stick or hand vacuum cleaner (1), on which a vacuum cleaner accessory (2) is arranged. Such a vacuum cleaner accessory (2) is attached with its connecting piece (3) to the suction piece (4) of the stick or hand-held vacuum cleaner (1). This area is shown more clearly in the enlargement.
In the usual case, the user must now, if he Vacuum cleaner accessory (2), press the push button (5) to detach the vacuum cleaner accessory (2) from the stick or hand-held vacuum cleaner (1).
To do this, he has to bend down. According to the invention, however, a contact surface (6) is arranged in the area of the push button (5) on the vacuum cleaner accessory (2). If the user now, according to FIG. 2, puts the stick or hand-held vacuum cleaner (1) vertically and pushes it forward a little, the pushbutton (5) comes to bear against the contact surface (6) on the vacuum cleaner accessory (2) and becomes pressed in so that the connection is unlocked and the connecting piece (3) and suction piece (4) can be detached from one another. This is done by pulling in the direction of the arrow, the vacuum cleaner accessory being briefly loaded by the user's foot.
The sequence of this unlocking and the structure of the mechanics is shown in detail in FIGS. 3-5.

Fig 3 zeigt die Verbindung im verriegelten Zustand. Der Anschlußstutzen (3) des Staubsaugerzubehörteils (2) und der Saugstutzen (4) des nicht dargestellten Staubsaugers sind ineinandergeschoben und durch den aus dem Anschlußstutzen (3) herausragenden Verriegelungsknopf (7) miteinander verbunden. Dieser Verriegelungsknopf (7) ist an einem Hebel (8) befestigt und durch die Feder (9) nach außen gedrückt.
An diesen Hebel (8) greift ein Zwischenhebel (10) an, der einstückig mit der Drucktaste (5) verbunden ist. Am Gehäuse (11) des Staubsaugerzubehörteils (2) ist eine Anlauffläche (6) angeformt.
Wird nun gemäß Fig. 4 der Anschlußstutzen (3) mit dem Saugstutzen (4) des Staubsaugers (nicht dargestellt) in die Senkrechte geschwenkt und darüber hinaus nach vorn gedrückt, so läuft die Drucktaste (5) gegen die Anlauffläche (6) an. Der an der Drucktaste (5) einstückig angeformte Zwischenhebel (10) wird verschwenkt und drückt das Ende (12) des Hebels (8) in die andere Richtung, so daß der am Hebel (8) angeordnete Verriegelungsknopf (7) nach innen gezogen wird und die Verriegelungsöffnung (13) im Saugstutzen (4) freigibt. Der Saugstutzen (4) kann somit in Pfeilrichtung vom Anschlußstutzen (3) abgezogen werden.Fig. 3 shows the connection in the locked state. The connector (3) of the vacuum cleaner accessory (2) and the suction connector (4) of the vacuum cleaner, not shown, are pushed into each other and connected to each other by the locking button (7) protruding from the connector (3). This locking button (7) is attached to a lever (8) and pressed outwards by the spring (9).
An intermediate lever (10), which is integrally connected to the push button (5), engages on this lever (8). A contact surface (6) is formed on the housing (11) of the vacuum cleaner accessory part (2).
If the connecting piece (3) with the suction piece (4) of the vacuum cleaner (not shown) is now pivoted into the vertical and also pushed forward, as shown in FIG. 4, the push button (5) runs against the contact surface (6). The integrally formed on the push button (5) intermediate lever (10) is pivoted and presses the end (12) of the lever (8) in the other direction, so that the locking button (7) arranged on the lever (8) is pulled inwards and the Locking opening (13) in the suction port (4) releases. The suction nozzle (4) can thus be removed from the connection nozzle (3) in the direction of the arrow.

Die Fig. 5 zeigt in vergrößerter Einzeldarstellung den Bereich der Verriegelung zwischen Anschlußstutzen (3) und Saugstutzen (4). Der Hebel (8) trägt den Verriegelungsknopf (7), welcher durch die Feder (9) gelagert ist. Demgegenüber liegt im Saugstutzen (4) die Verriegelungsöffnung (13), welche im verriegelten Zustand den Verriegelungsknopf (7) aufnimmt. Zusätzlich ist am Anschlußstutzen (3) eine elastische Haltenase (14) fest angeordnet, welche bis in den Bereich der Verriegelungsöffnung (13) hineinragt und durch einen einseitigen Schlitz (15) durch den Verriegelungsknopf (7) hindurchtritt. Diese Haltenase (14) verhindert das unbeabsichtigte Lösen der Verbindung. Dies könnte geschehen, wenn der Benutzer den Staubsauger in die Senkrechte bringt, um ihn mitsamt Staubsaugerzubehörteil (2) aufzuhängen. Durch die kurzzeitige senkrechte Position ist die Verbindung kurzzeitig gelöst, und es könnte geschehen, daß beim Aufhängen das Staubsaugerzubehörteil (2) abrutschen würde.
Das verhindert die Haltenase (14), die das Eigengewicht des Staubsaugerzubehörteils (2) trägt, ohne die Verbindung zu lösen.5 shows an enlarged individual representation of the area of the locking between the connection piece (3) and the suction piece (4). The lever (8) carries the locking button (7) which is supported by the spring (9). In contrast, in the suction port (4) is the locking opening (13) which receives the locking button (7) in the locked state. In addition, an elastic retaining lug (14) is fixedly arranged on the connecting piece (3), which protrudes into the area of the locking opening (13) and passes through the locking button (7) through a slot (15) on one side. This retaining lug (14) prevents the connection from being unintentionally released. This could happen if the user brings the vacuum cleaner upright to hang it together with the vacuum cleaner accessory (2). Due to the short vertical position, the connection is temporarily disconnected, and it could happen that the vacuum cleaner accessory (2) would slide off when hanging up.
This prevents the retaining lug (14), which carries the weight of the vacuum cleaner accessory (2) without loosening the connection.

Fig. 6 zeigt noch einmal das Staubsaugerzubehörteil (2) mit Anschlußstutzen (3). An ihm erkennt man den Verriegelungsknopf (7), welcher unten von der Haltenase (14) durchdrungen ist. Die Drucktaste (5) liegt in Höhe der Anlauffläche (6) und kann gegen diese anlaufen.
Solche Verbindungen sind selbstverständlich für alle Staubsaugerverbindungen denkbar, z.B. auch für Schlittenstaubsauger, bei denen das Staubsaugerzubehörteil nicht direkt am Anschlußstutzen eines Staubsaugers, sondern an einem Saugrohr befestigt ist.Fig. 6 shows again the vacuum cleaner accessory (2) with connection piece (3). It shows the locking button (7), which is penetrated at the bottom by the retaining lug (14). The push button (5) is at the level of the contact surface (6) and can run against it.
Such connections are of course conceivable for all vacuum cleaner connections, for example also for sledge vacuum cleaners, in which the vacuum cleaner accessory is not attached directly to the connecting piece of a vacuum cleaner, but to a suction pipe.
