Benefits of technology

[0010]It is an advantage of the present invention to provide an improved stick vac cleaner of the second general type described above.
[0011]According to the present invention there is provided a stick-vac cleaner comprising a handheld vacuum cleaner which is attached to an elongate, rigid wand and which is fluidly connected to a cleaner head provided at the end of the wand, wherein the cleaner head is connected to the wand via a mechanical steering couple for directionally steering the cleaner head in plane parallel contact with the floor as the wand is rotated about its axis.
[0012]By providing a mechanical steering couple between the wand and cleaner head according to the present invention, the maneuverability of the stick-vac cleaner is greatly improved compared to conventional stick-vac cleaners of the second general type.
[0013]Any suitable mechanical steering couple may be used. In particular, the mechanical steering couple may be configured to constrain the wand and the cleaner head for

Problems solved by technology

In the case of these stick vac cleaners, the wand and floor tool are typically conceived and marketed as low-cost accessories for a handheld vacuum clean

Embodiment Construction

[0030]FIG. 1 shows a stick-vac cleaner 1 in use, comprising a handheld vacuum cleaner 3 which is carried in the hand, an elongate wand 5 attached to the handheld cleaner 3 and which reaches down to the floor and a cleaner head 7 provided at the end of the wand 5, which makes contact with the floor (the floor itself, though implicit, is not explicitly shown in FIG. 1).

[0031]Referring to FIG. 2, the handheld vacuum cleaner 3 comprises a motor-driven fan which is arranged inside a motor casing 9 for drawing air in through a suction nozzle 11 positioned at the front of the hand held vacuum cleaner 3. The elongate wand 5 is connected to the suction nozzle 11, and the cleaner head 7 is in turn connected to the lower end of the wand 5. In use, dirty air is drawn in through a suction opening 12 (FIG. 3) on the underside of the cleaner head 7 and is ducted to the suction nozzle 11 on the handheld vacuum cleaner 3, through the wand 5.

[0032]Dirty air entering the suction nozzle 11 passes throu...

Abstract

A vacuum cleaner of the stick-vac type, the cleaner including a handheld vacuum cleaner which is attached to an elongate, rigid wand and which is fluidly connected to a cleaner head provided at the end of the wand. The cleaner head is connected to the wand via a mechanical steering couple for directionally steering the cleaner head in plane parallel contact with the floor as the wand is rotated about its axis.

Description

REFERENCE TO RELATED APPLICATIONS[0001]This application claims the priority of United Kingdom application No. 1016563.7, filed Oct. 1, 2010, the entire contents of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to the field of vacuum cleaners, and more specifically to “stick-vac” type vacuum cleaners of the general type comprising a handheld vacuum cleaner which is attached to an elongate, rigid wand and which is fluidly connected to a cleaner head provided at the end of the wand.BACKGROUND OF THE INVENTION[0003]Broadly speaking, there are four types of vacuum cleaner: “upright” vacuum cleaners, “cylinder” cleaners (also referred to as “canister” cleaners), “handheld” vacuum cleaners and “stick” vacuum cleaners, the latter being popularly referred to as “stick-vac” cleaners, or simply “stick-vacs”.[0004]Upright cleaners and cylinder cleaners are well known. They tend to be mains-operated and are used for relatively heavy-duty cle...
