Abstract

Beschrieben und dargestellt ist ein Staubsauger-Saugrohr (1) mit mindestens einem Innenrohr (2), mindestens einem Außenrohr (3), und mindestens einer Verriegelungsvorrichtung (4), wobei das Innenrohr (2) eine Zahnleiste (5) mit Zähnen aufweist, wobei die Verriegelungsvorrichtung (4) am Außenrohr (3) befestigt ist, wobei die Verriegelungsvorrichtung (4) durch manuelle Betätigung durch einen Benutzer aus einer Verriegelungsposition in eine Freigabeposition verbringbar ist, wobei die Verriegelungsvorrichtung (4) eine Zahnstange (6) mit Zähnen aufweist, und wobei in der Verriegelungsposition die Zahnstange (6) im Eingriff mit der Zahnleiste (5) des Innenrohrs (2) gehalten wird, wodurch die Position des Innenrohrs (2) relativ zum Außenrohr (3) festgelegt ist.Described and illustrated is a vacuum cleaner suction tube (1) having at least one inner tube (2), at least one outer tube (3), and at least one locking device (4), wherein the inner tube (2) has a toothed bar (5) with teeth, wherein the locking device (4) is fastened to the outer tube (3), wherein the locking device (4) can be moved from a locking position into a release position by manual operation by a user, the locking device (4) having a toothed rack (6), and wherein in the locking position, the rack (6) is held in engagement with the rack (5) of the inner tube (2), whereby the position of the inner tube (2) is fixed relative to the outer tube (3).

Ein Staubsauger-Saugrohr, das eine präzise und unkomplizierte Einstellung der Länge ermöglicht, wird realisiert, indem die Verriegelungsvorrichtung (4) durch Verschiebung relativ zum Außenrohr (3) und in Achsrichtung des Außenrohrs (3) in die Freigabeposition verbringbar ist, und dass die Zahnstange (6) in der Freigabeposition durch eine Relativkraft zwischen Außenrohr (3) und Innenrohr (2) ohne den Einfluss einer Federkraft aus dem Eingriff mit der Zahnleiste (5) herausdrückbar ist, indem die Zahnflanken der Zähne der Zahnleiste (5) die Zahnflanken der Zähne der Zahnstange (6) nach oben schieben, wodurch das Innenrohr (2) relativ zum Außenrohr (3) verschiebbar ist.

Figure imgaf001
A vacuum cleaner suction tube, which allows a precise and straightforward adjustment of the length is realized by the locking device (4) by displacement relative to the outer tube (3) and in the axial direction of the outer tube (3) can be brought into the release position, and that the rack (6) in the release position by a relative force between the outer tube (3) and inner tube (2) without the influence of a spring force out of engagement with the toothed strip (5) can be pushed out by the tooth flanks of the teeth of the toothed strip (5) the tooth flanks of the teeth push the rack (6) upwards, whereby the inner tube (2) relative to the outer tube (3) is displaceable.
