Benefits of technology

[0008] Further describing the invention, the hose body includes a reinforcing wire and a collapsible wall. Further, the first coupler carries a first connector and the second coupler carries a second connector. In one possible embodiment the first and second connectors are cooperating male and female connectors that secure two like hoses together.

Problems solved by technology

While such vacuum cleaner designs are particularly useful and beneficial for an operator, some operators have been frustrated by the limited length of hose that is provided on such vacuum cleaners.

Embodiment Construction

[0017] Reference is now made to FIG. 1 showing the electrified extension hose 10 of the present invention in use interconnecting the original equipment hose H and wand W of the canister vacuum cleaner V. As illustrated, that vacuum cleaner V includes a canister housing C mounted on wheels L for movement across the floor. The wand W carries a powerhead P including a motor driven rotary agitator A. A switch S on the wand W allows the operator to turn on both the suction generator G in the canister housing and the motor M of the powerhead P for driving the agitator A. Advantageously, the extension hose 10 of the present invention includes the necessary electrical circuitry to allow proper interconnection between the switch S on the wand W, the motor M in the powerhead P and the suction generator G in the canister housing C to allow proper operation.

[0018] The electrified extension hose 10 includes a flexible hose body 12 including a lumen that defines a dirty air pathway. The hose bod...

Abstract

An electrical extension hose includes a flexible hose body having first and second ends. A first electrified coupler is provided at the first end. A second electrified coupler is provided at the second end. At least two electrical conductors interconnect the first and second couplers. Further, the first and second couplers are capable of mating interconnection. Thus any number of electrical extension hoses may be connected together to construct a working hose of desired length.

Description

[0001] This application claims the benefit of U.S. Provisional Patent Application Ser. No. 60 / 490,633 filed on Jul. 28, 2003.TECHNICAL FIELD [0002] The present invention relates generally to the floor care equipment field and, more particularly, to an electrified extension hose for a vacuum cleaner specially designed to allow one or more such extension hoses to be connected together so the vacuum cleaner operator may construct a hose of desired length. BACKGROUND OF THE INVENTION [0003] It has long been known in the art to equip canister vacuum cleaners with an electrified hose in order to power a motor for driving the rotary agitator of a power nozzle assembly. More recently, stretch hoses have been utilized so that the operator has an additional length of hose to allow operation of the power nozzle assembly a greater distance from the canister of the vacuum cleaner. [0004] In a recent development, the assignee of the present invention has designed an upright vacuum cleaner incorpo...
