Abstract
A wand for a domestic appliance (e.g., 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.
Claims33
A wand configured for use in a domestic appliance, comprising a storage tube and a plurality of movable tubes which are dimensioned to telescope inside the storage tube and one another and a securing mechanism associated with each tube operable to secure its respective movable tube in an extended position with respect to an adjacent tube and releasable to allow telescopic sliding of the movable tube with respect to its adjacent tube, the securing mechanisms being arranged so as to lie adjacent one another when the movable tubes are in a fully retracted position, each securing mechanism being configured so as to be released by an adjacent securing mechanism when the respective movable tube is retracted,
- wherein each securing mechanism is configured to be movable between a locked position in which it locks its respective tube to an adjacent tube and an unlocked position in which it allows movement between the tubes, adjacent securing mechanisms being positioned on adjacent tubes and configured such that, when the respective tubes are retracted, one securing mechanism applies a radially outward force against an underside of its outwardly adjacent securing mechanism so as to move the outwardly adjacent securing mechanism into the unlocked position.
