Abstract
A wand for a domestic appliance (e.g., a vacuum cleaner) includes a plurality of tubes which are dimensioned to telescope inside one another. Each tube is associated with a securing mechanism for securing the tube in an extended position with respect to another of the tubes. Adjacent securing mechanisms are positioned on their respective tubes such that, when the tubes are retracted, one securing mechanism presses against another to release the other securing mechanism. Thus, a user does not need to separately operate each securing mechanism when extending the wand. Also, the tubes automatically secure themselves in an extended position with respect to one another. A hook on the widest tube cooperates with a collar on the narrowest tube to retain the tubes in a stored position.
