  • Method of linkage and locking of connecting coupling member to nozzle base of a vacuum cleaner
    Patent number: 6571425
    Abstract: An upright vacuum cleaner (10) includes an upper housing (12) and a nozzle base (14). An underside (20) of the nozzle base includes a main suction opening (26) formed therein which is in fluid communication with the upper housing via a hose assembly (28). The hose assembly is coupled to the nozzle suction opening via a coupling member (40). The coupling member is substantially cylindrical in shape and is dimensioned to be inserted into a receiving portion (42) of the nozzle base. The coupling member includes a first tapered end (60) dimensioned to be frictionally fit within a suction inlet (44) of the receiving portion. A second end (62) of the coupling member is configured to be supported on a rear wall (50) of the receiving portion. A quarter turn thread segment (72) is disposed on the coupling member's peripheral surface.
