Abstract
A vacuum cleaner wand includes inner and outer relatively telescopable pipes, a cord magazine chamber on the outer pipe, a sheath tube connected to the inner pipe and slidably extending into the chamber, a slider guided slidably parallel to the sheath tube in the chamber, and a flexible electrical cord. The cord extends along inside the sheath tube, bends 180° as a fixed loop at an end of the sheath tube, extends back between the sheath tube and the slider, bends 180° as a movable loop through an opening in the slider, and extends between the slider and a sidewall of the chamber. Thereby the cord has an adjustable extended length corresponding to the selected telescoped length of the wand. The sliding sheath tube slides the cord, which in turn moves the slider, so that the cord remains kink-free.
