Description
Es ist bekannt, Staubsauger auf mehreren, insbesondere auf drei Rollen zu lagern, von denen eine um eine senkrechte Achse schwenkbar ist, während die Achsen der übrigen Rollen starr am Staubsaugergehäuse bzw. an einem besonderen Fahrgestell angeordnet sind. Bei Staubsaugern liegender Bauart erfolgt die Anordnung der drei Rollen in der Weise, daß an einem Ende des StaubSaugers die beiden nicht schwenkbaren Rollen nebeneinander in einer Achse angeordnet sind, während sich die schwenkbare Rolle an dem anderen Ende des Staubsaugers befindet. It is known to store vacuum cleaners on several, in particular on three, rollers one of which is pivotable about a vertical axis, while the axes of the other rollers are rigid on the vacuum cleaner housing or are arranged on a special chassis. More horizontal with vacuum cleaners Design is the arrangement of the three rollers in such a way that at one end of the vacuum cleaner the two non-pivotable rollers are arranged next to each other in an axis, while the pivotable roller is on the other end of the vacuum cleaner.
Um die Standfestigkeit eines derartigen liegenden Staubsaugers zu erhöhen, beispielsweise beim Reinigen von Treppen, in welchem Falle der auf den Stufen stehende; Staubsauger durch die Bewegungen des Saug-Schlauches leicht von seiner Standfläche hinuntergezogen werden kann, ist schon vorgeschlagen worden, die schwenkbare Rolle festzustellen. Hierzu bedient man sich einer am Boden des Staubsaugergehäuses angeordneten Verriegelung, deren bewegbarer Teil zwischen Rolle und Staubsaugergehäuse eingeschoben wird und dabei die Rolle festklemmt. Durch die Erfindung wird die Standsicherheit eines Staubsaugers, insbesondere liegender Bauart, mit drei Laufrollen, von denen die eine schwenkbar angeordnet ist, mit einfacheren Mitteln erzielt. Erfindungsgemäß wird mit der schwenkbar angeordneten Laufrolle ein umlegbares, die Laufrolle vom Boden abhebendes Stützgestell verbunden. Vorzugsweise besteht hierbei das Stützgestell aus einem am Staubsaugergehäuse drehbar gelagerten Bügel, der mit Anschlägen versehen ist, die die standfeste Lage des Bügels bei angehobener Schwenkrolle sichern. Der Bügel kann ferner mit einer Feder versehen sein, durch die er bei Anheben des Staubsaugers selbsttätig in seine Ruhelage zurückgezogen wird. Um 'ein Verrutschen des Bügels auf dem Boden zu erschweren, wird der Bügel zweckmäßig an seinem Fuß mit einer Gummistütze oder mit mehreren Gummistützen verseilen.To increase the stability of such a lying vacuum cleaner, for example when cleaning stairs, in which case the one standing on the steps; Vacuum cleaner by the movements of the suction hose can easily be pulled down from its base is already proposed have been to determine the pivoting role. For this purpose one uses one arranged on the bottom of the vacuum cleaner housing Lock, the movable part of which is inserted between the roller and the vacuum cleaner housing and thereby jamming the roll. The invention increases the stability of a vacuum cleaner, in particular horizontal design, with three rollers, one of which is pivotable, achieved with simpler means. According to the invention With the swiveling castor, a foldable support frame that lifts the castor from the ground becomes tied together. The support frame preferably consists of one on the vacuum cleaner housing rotatably mounted bracket, which is provided with stops that the stable position of the bracket Secure with the swivel castor raised. The bracket can also be provided with a spring by which it automatically retracts into its rest position when the vacuum cleaner is lifted will. In order to make it more difficult for the bracket to slip on the floor the bracket expediently on its foot with a rubber support or with several rubber supports strand.
In der Zeichnung ist der Gegenstand der Erfindung beispielsweise veranschaulicht, und zwar zeigen:In the drawing, the subject matter of the invention is illustrated, for example, and although show:

angeordnet. Die zweite feste Rolle liegt mit der in Abb. ι dargestellten Rolle 2 in einer Achse und ist daher in der Zeichnung ,nicht, sichtbar. Oberhalb der Schwenkrolle 3 isf.; an dem Staubsaugergehäuse ein Bügel 4 drefibar gelagert. Zweckmäßig wird der Bügel 4 an einer Halteplatte 5 der Schwenkrolle mittels eines Gelenkes 6 angebracht. An dem Bügel 4 sitzen Anschlagarme 7, durch die bei angehobener Rolle (vgl. Abb. 2) der Bügel 4 in standfester Lage gehalten wird. Wie aus Abb. 3 hervorgeht, ist an dem Bügel eine Rückzugfeder 8 vorgesehen, die nach Anheben des Staubsaugers den Bügel 4 aus seiner Stützstellung (Abb. 2) in die Ruhelage (Abb. ι und 3) zurückholt. Der Fuß des Bügels ist mit Gummihülsen 9 versehen, die ein Verrutschen des Bügels nach Anheben der Schwenkrolle erschweren.arranged. The second fixed role is with the roller 2 shown in Fig. ι in one axis and is therefore not in the drawing, visible. Above the caster 3 isf .; a bracket 4 drefibar on the vacuum cleaner housing stored. The bracket 4 is expediently attached to a retaining plate 5 of the swivel roller by means of a joint 6 attached. On the bracket 4 are seated stop arms 7 through which when the roller is raised (see Fig. 2), the bracket 4 is held in a stable position. As is apparent from Fig. 3, a return spring 8 is provided on the bracket, which after Lift the vacuum cleaner the bracket 4 from its support position (Fig. 2) into the rest position (Fig. Ι and 3) retrieved. The foot of the bracket is provided with rubber sleeves 9, which make it difficult for the bracket to slip after the swivel castor has been lifted.
