Abstract (en)

[origin: DE19924450C1] The suction tube has an outer tube, an inner tube with an axial latching strip, and at least one locking body (18) movable along the tube, with locking surfaces for engagement with counter locking surfaces in the latching strip. There is a collar on the outer tube with a housing containing the locking body, a spring (23) securing the locking position and an actuator for the locking body. The actuator is a rotation body (22) acting directly on the locking body and the locking position is secured by the spring.

Abstract (de)

Dargestellt und beschrieben ein teleskopierbares Staubsauger-Saugrohr (10) mit einem Außenrohr (12), einem mit einer sich axial erstreckenden Rastleiste (15) versehenen Innenrohr (11), mindestens einem Sperrflächen (17) aufweisenden, in Richtung einer Längsmittelachse (x) des Staubsauger-Saugrohres (10) bewegbaren Sperrkörper (18), der in mit Gegensperrflächen (16) versehene Rastausnehmungen (14) der Rastleiste (15) zeitweise eingreift, einem am Außenrohr (12) angeordneten, das Innenrohr (11) übergreifenden Manschette (20) einschließlich eines Gehäuses (21), in dem der Sperrkörper (18), eine die Sperrstellung sichernde Feder (23) und eine Betätigungsvorrichtung (22) für den Sperrkörper (18) angeordnet sind. Aufgabe der Erfindung ist es, ein neues teleskopierbares Staubsauger-Saugrohr (10) zu schaffen, bei dem konstruktiv bedingt der oben dargelegte Fall nicht eintreten kann. Die Lösung dieser Aufgabe ergibt sich dadurch, dass die Betätigungsvorrichtung (22) als unmittelbar auf den Sperrkörper (18) einwirkender Rotationskörper (22,51,61) ausgebildet ist und dass die Sperrstellung des Rotationskörpers (22) durch die Feder (23)gesichert wird. <IMAGE>
