Method of linkage and locking of connecting coupling member to nozzle base of a vacuum cleaner
First Claim
1. An upright vacuum cleaner comprising:
- a nozzle base having a suction inlet;
an upper housing hingedly connected to the nozzle base, the upper housing being selectively moveable between a generally vertical position and a generally inclined position;
a tube assembly disposed at least partially within the upper housing;
a receiving portion located within the nozzle base; and
a coupling member configured to be received by the receiving portion for coupling the tube assembly to the suction inlet, the coupling member having a thread segment disposed on its outer surface dimensioned to cooperate with a surface of the receiving portion, the thread segment and the cooperating surface of the receiving portion being dimensioned to urge the coupling member into a friction fit seal with the suction inlet upon less than one full rotation of the coupling member.

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. Upon rotation of the coupling member, the thread segment threadingly cooperates with the rear wall of the receiving portion so that the coupling member is urged into a friction fit seal with inlet opening (44). A finger (70) is provided on the peripheral surface of the coupling member to assist in rotating the coupling member.
