发明名称 VACUUM-CLEANER-HOSE ASSEMBLY HAVING A SWIVEL BEND AND VACUUM CLEANER COMPRISING SUCH ASSEMBLY
摘要 <p>A vacuum-cleaner-hose assembly comprises a vacuum-cleaner hose (6, 36) and a swivel coupling (3, 33) for coupling the vacuum-cleaner hose (6, 36) to a housing (4) of a vacuum-cleaner so as to allow it to be swivelled about a swivel axis (5) and at an angle relative to said swivel axis (5). The swivel coupling (3, 33) comprises a hose guide (8, 38) which surrounds a flexible portion (24, 54) of the vacuum-cleaner hose (6, 36) and holds said portion of the vacuum-cleaner hose (6, 36) in a curved position. Since the vacuum-cleaner hose is held in a curved position, the connection of the vacuum-cleaner hose to the swivel coupling can be arranged closer to that end of the swivel coupling which is to be connected to the vacuum-cleaner, as a result of which the swivel coupling can be smaller and the swivel coupling or at least a combination of the swivel coupling and an adjoining coupling portion of the vacuum-cleaner hose projects less far in relation to the swivel axis of the swivel coupling.</p>
