Abstract

A wand for an appliance includes 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.

Dependent claims

A wand, for an appliance, comprising:

first and second tubes;
and
a support mechanism,
one of the first and second tubes being slideable telescopically within the other of the first and second tubes along a common axis,
the first and second tubes being selectively securable to one another in an extended position or to allow movement therebetween, the support mechanism being located between overlapping portions of the first and second tubes,
wherein the first tube comprises a first tapered end portion, the second tube comprises a second tapered end portion, and the support mechanism comprises a first element having a first tapered portion and a second element having a second tapered portion, the first and second tapered portions being axially spaced from one another along the common axis, the first tapered portion arranged to provide support between the first and second tubes by engagement with the first tapered end portion, the second tapered portion arranged to provide support between the first and second tubes by engagement with the second tapered end portion, and one of the first and second elements being movable with respect to the first and second tubes along the common axis.
