  • Publication number: 20090072528
    Abstract: A wand for an appliance includes comprises first and second tubes and a support mechanism, in which the second tube slides telescopically within the first tube along a common axis. The first and second tubes are arranged to be selectively secured to one another in an extended position or to allow movement therebetween and the support mechanism is located between overlapping portions of the tubes. The support mechanism includes tapered portions arranged to provide support between the tubes at separate points along the common axis of the tubes. By supporting adjacent tubes at a plurality of points along the common axis, the tubes are held more firmly with respect to one another. One tapered portion is able to move with respect to the tubes along the common axis, which reduces play between the tubes. The structural strength and quality of the wand are improved.
