Electric vacuum cleaner suction hose has spring-loaded ratchet element securing telescopic tubular sections of hose in required relative position and cooperating 2-armed operating lever

摘要

The suction hose (1) has at least 2 telescopic tubular sections (2,3,4) adjusted relative to one another to provide a required suction hose length and locked in the required position by a spring-loaded ratchet element (6), providing an axially and radially releasable coupling. The ratchet element is operated by a 2-armed operating lever (7) provided by the outer tubular section, with one arm (7a) of the operating lever having an end projection (13) cooperating with an indent (15) in the outside (3a) of the inner tubular section.
