Abstract

In accordance with the present invention, there is provided an improved wand for connecting a vacuum cleaner suction nozzle having an electric motor therein to a suction hose. A wand of this type normally serves as both a rigid handle for manipulating the nozzle and as a conduit for the passage of air from the nozzle to the hose. In addition, the present wand is provided with a sheath of preferably electrical insulating material for retaining an electric cord for supplying current to the motor in the nozzle from conductors carried by the suction hose.

Claims

1. In a wand for a vacuum cleaner, a tubular sheath formed with a channel extending lengthwise along one exterior side thereof, electric conductors disposed in said channel, a first tubular conduit insertable axially into said sheath from one end thereof and extending therein to adjacent the opposite end of said sheath, a second tubular conduit insertable axially into said opposite end of said sheath for telescopic engagement within said sheath with the adjacent end of said first tubular conduit, releasable locking means carried by one of said tubular conduits in the region of the telescopic engagement and engageable with the other of said tubular conduits for coupling said conduits together, said sheath being formed with an aperture through the side thereof in said region of the telescopic engagement, and manually operable means accessible through said aperture for releasing said locking means.

2. A wand as described in claim 1 in which said first conduit is telescopically received within said second conduit and is formed with a recess in the portion thereof which is received within said second conduit, said locking means comprising a spring-loaded detent carried by said second conduit engageable with said recess to lock said conduits together, and a finger-operable member accessible through said aperture for disengaging said detent from said recess.

3. A wand as described in claim 2 in which said detent is mounted on a resilient arm secured on the exterior of said second conduit, said detent being urged by said arm inwardly through an opening in said second conduit to engage said recess, and a cam surface formed on said sheath to be engaged by said arm for moving said detent outwardly through said opening as said second conduit is inserted into said opposite end of said sheath to cause said detent to clear the end of said first conduit.

4. A wand as described in claim 2 in which said detent is mounted on a resilient arm secured on the exterior of said second conduit, said detent being urged by said arm inwardly through an opening in said second conduit to engage said recess, said arm being accessible through said aperture for lifting movement by the finger to release said detent from said recess, and means on said sheath for limiting the extent of said movement.
