Abstract

Die Erfindung betrifft ein teleskopierbares Staubsauger-Saugrohr (10), mit einem Innenrohr (12) und einem Außenrohr (11) und einer endseitig am inneren Ende des Innenrohres (12) befestigten, im Zwischenraum (14) zwischen Innen- (12) und Außenrohr (11) angeordneten Dichtungshülse (13) aus Kunststoff, deren Hülsenwandung einen ersten, der Innenstirnfläche (18) des Innenrohres (12) zugeordneten, ersten axialen Endabschnitt (15) und einen der Innenstirnfläche (18) des Innenrohres (12) abgewandten, zweiten axialen Endabschnitt (17) aufweist, wobei der Zwischenraum (14) zwischen Innen- (12) und Außenrohr (11) mittels einer von der Dichtungshülse (13) ausgebildeten, sich an einer Innenmantelfläche (26) des Außenrohres (11) abstützenden Dichtlippe (27) abgedichtet ist.The invention relates to a telescopic vacuum cleaner suction pipe (10), with an inner tube (12) and an outer tube (11) and one end attached to the inner end of the inner tube (12), in the intermediate space (14) between inner (12) and outer tube (11) arranged sealing sleeve (13) made of plastic, the sleeve wall of a first, the inner end face (18) of the inner tube (12) associated, first axial end portion (15) and one of the inner end face (18) of the inner tube (12) facing away from the second axial End portion (17), wherein the intermediate space (14) between the inner (12) and outer tube (11) by means of one of the sealing sleeve (13) formed on an inner circumferential surface (26) of the outer tube (11) supporting the sealing lip (27) is sealed.

Aufgabe der Erfindung ist es, Staubsauger Saugrohre weiter zu verbessern, insbesondere soweit es die Handhabung bei der Montage, eine vereinfachte Produktion der Dichtungshülse und eine weiter verbesserte Abdichtung des Staubsauger-Saugrohres gegen Leckluftströme betrifft.The object of the invention is to further improve vacuum cleaner suction pipes, especially as far as the handling during assembly, a simplified production of the sealing sleeve and a further improved sealing of the vacuum cleaner suction pipe against leakage air flows.

Gelöst wird die Aufgabe von einem Staubsauger-Saugrohr (10) mit den Merkmalen des Anspruches 1, wobei insbesondere der zweite axiale Endabschnitt der Hülsenwandung unter Ausbildung einer innenumfänglichen Führungsfläche und unter Ausbildung einer sich an der Innenmantelfläche (26) des Außenrohres (11) abstützenden zusätzlichen Dichtlippe (30) trichterförmig erweitert ist.
