Abstract

Die Erfindung betrifft ein teleskopierbares Staubsauger-Saugrohr (1) mit einem Außenrohr (2), einem darin teleskopierbaren Innenrohr (3) mit Rastvertiefungen (7), einer Verdrehsicherung (4d; 16) und einer Verriegelungseinrichtung mit einem Rastelement (15), welches von einem ihm etwa diametral gegenüberliegenden Betätigungselement (5) aus der Rastvertiefung (7) auszurücken ist, wobei die Verriegelungseinrichtung aus einer zumindest das Innenrohr (3) formschlüssig umgreifenden Bügelfeder (6) besteht, die unter Vorspannung einer Feder das Rastelement (15) in eine in Teleskoprichtung nächstgelegene Rastvertiefung (7) des Innenrohres (3) wieder einrückt
Der Erfindung liegt die Aufgabe zugrunde, ein teleskopierbares Staubsauger-Saugrohr der eingangs genannten Gattung zu schaffen, welches nicht nur den Herstellungs- und Montageaufwand der Verriegelungstechnik erheblich herabsetzt, sondern auch stets eine sichere, stoßartigen Druckbelastungen standhaltende Verriegelung bei einfacher ergonomischer Handhabung gewährleistet.
Diese Aufgabe wird in Verbindung mit dem eingangs genannten Gattungsbegriff erfindungsgemäß dadurch gelöst, daß die Bügelfeder (6) aus einer ringförmigen Feder mit rechteckigem oder kreisrundem Querschnitt besteht, die alternativ das Innenrohr (3) oder eine Führungshülse (4) oder das Außenrohr (2) nicht nur form-, sondern auch kraftschlüssig umgreift und deren freie Enden (12, 13) vom Betätigungselement (5) zum Lösen der Verriegelung auseinanderzuspreizen sind, wodurch das Rastelement (15) aus der Rastvertiefung (7) herausgehoben ist.
