Abstract

A vacuum cleaner nozzle having a first nozzle part (11) which has brush elements (23) or the like facing the floor and a second nozzle part (25) which is movably arranged with respect to the first part (11) and which has at least one suction opening (27) through which air flows to an outlet tube (13) connected to the nozzle. The second nozzle part (25) is supported by the first nozzle part (11) by means of a resilient element (31). The resilient element maintains the second part (25) above the floor when the nozzle is moved on a hard surface and allows the second part (25) to move toward the floor when the nozzle is moved on a soft surface, such as a soft carpet.

Claims

1. A vacuum cleaner nozzle comprising a first nozzle part (11) which has brush elements (23) facing a floor and defining a space (24) in which a second nozzle part (25) is movably arranged with respect to the first part (11), the second nozzle part having at least one suction opening (27) through which air flows to an outlet tube (13) which is connected to the nozzle, wherein the second nozzle part (25) is supported from the first nozzle part (11) by means of a resilient element (31), and the resilient element is operable to maintain the second nozzle part (25) above the floor when the nozzle is moved on a rigid surface and permits the second nozzle part (25) to move toward the floor when the nozzle is moved on a yieldable surface.

2. A vacuum cleaner nozzle according to claim 1, wherein the second nozzle part (25) is connected to the first nozzle part (11) by a flexible sealing member (29).

3. A vacuum cleaner nozzle according to claim 2, wherein the second nozzle part (25) comprises a plate (26) whose lower side forms an inlet part with channels opening into the suction opening (27), and wherein the suction opening is arranged centrally on the plate and the sealing member (29) surrounds the suction opening.

4. A vacuum cleaner according to claim 1, wherein opposite ends of the first nozzle part (11) are provided with a supporting wheel 22.

5. A vacuum cleaner nozzle according to claim 1, wherein at least one brush element is placed in front of the second nozzle part.

6. A vacuum cleaner according to claim 1, further comprising means (34) for limiting downward movement of the second nozzle part (25).

7. A vacuum cleaner nozzle according to claim 1, wherein at least one brush element is placed behind the second nozzle part.

8. A vacuum cleaner nozzle comprising a first nozzle part (11) and a second nozzle part (25), said first nozzle part (11) being connected to an outlet tube (13) via a pivot (12) with at least one wheel being located near said pivot, said first nozzle part having brush elements (23) facing a floor and defining a space (24) in which the second nozzle part (25) is movably arranged with respect to said first nozzle part (11), said second nozzle part (25) having at least one suction opening (27) through which air flows toward the outlet tube (13), wherein the second nozzle part is supported from the first nozzle part by a resilient element (31), and said resilient element is operable to maintain the second nozzle part (25) above a floor when the nozzle is moved across a rigid surface and permits the second nozzle part (25) to move toward the floor when the nozzle is moved across a yieldable surface.

9. A vacuum cleaner nozzle according to claim 8, wherein the second nozzle part (25) is connected to the first nozzle part (11) by a flexible sealing member (29).

10. A vacuum cleaner nozzle according to claim 9, wherein the second nozzle part (25) comprises a plate (26) whose lower side forms an inlet part with channels opening into the suction opening (27), and wherein the suction opening is arranged centrally on the plate and the sealing member (29) surrounds the suction opening.

11. A vacuum cleaner according to claim 8, wherein opposite ends of the first nozzle part (11) are provided with a supporting wheel 22.

12. A vacuum cleaner nozzle according to claim 8, wherein at least one brush element is placed in front of the second nozzle part.

13. (new) A vacuum cleaner according to claim 8, further comprising means (34) for limiting downward movement of the second nozzle part (25) .

14. A vacuum cleaner nozzle according to claim 8, wherein at least one brush element is placed behind the second nozzle part.
