<p>An extensible hose assembly, particularly for a carpet-, floor-, moquette-, wall-cleaner or the like, comprising at least one first conduit (2) and at least one second conduit (3). The first conduit (2) is composed of at least one first pair (4, 4') of substantially rigid tubular members, coupled together in telescopically sliding relationship, whereas the second conduit (3) is made of a material adapted to convey a working fluid at a predetermined maximum temperature. The assembly further includes first connecting means (6) for joining an end (5) of the second conduit (3) to a source (S) of working fluid and means (U) for delivering the latter at the opposite free end (5') of said second conduit (3). The second conduit (3) is substantially unitary and flexible and is of variable configuration and length to adjust the distance (1) between the above mentioned opposite free ends (5, 5'). Also, the first conduit (2) is external to the second conduit (3) to define a mechanically protective covering, adapted to be manually grasped by a user, and to fit length adjustments on the second conduit (3).</p> |
