<p>A vacuum cleaner device has a nozzle which, via a pivotal connection, is connectable to a lower end of a vacuum cleaner pipe which, at its upper end via a vacuum cleaner hose is connectable to a vacuum cleaner. The vacuum cleaner pipe has inner and outer parts (1, 2; 10) which are longitudinally displaceable in relation to one another, and a joint (12, 25) whose pivot axis is parallel with the pivot axis of the connection. The joint (12, 25) of the vacuum cleaner pipe is disposed on the inner section (1, 2) and, for locking of the joint, is insertable in the outer section (10).</p> |
