The drawing shows in

Pig. 1 is a perspective view of a vacuum cleaner with a vertical suction arrangement according to the invention;

Pig. 2 is an enlarged perspective view of a Nozzle arrangement according to the invention;

'Fig. 3 is a bottom view of the nozzle assembly, with a Part of the brush core has broken away;

Pig. Figure 4 is a section along line 4-4 of Pig. 3 under ■ '/ i ed would result in the brush position before insertion their sweeping effectj and in

Pig. 5 shows a view corresponding to FIG. 4 for reproduction the sweeping effect of the brush.

The vacuum cleaner 1 in the illustrated embodiment contains a suction nozzle 2, a container 3 »a Liotor suction fan unit 4 and a handle 5.

JJie nozzle 2 carries the vacuum cleaner 1 on the floor surface and is moved back and forth across the floor to collect dirt and dust. A suction pipe 6 is general inserted between nozzle 2 and container 3, so that the operator stand and the vacuum cleaner with the handle 5 can be handled easily.

According to Figures 2 to 5, the suction pipe 6 and 9 forms an extension of downwardly open nozzle housing 7 with the side walls 8 A Plansch 10 projects forwardly from the housing 7 and is particularly solid construction so that it

the arrangement during suction operation, for example when bumping into it able to protect. The splash 10 is provided with a slot 11 provided so that air and dust particles over the carpet or the like, and under the front part of the housing 7 can flow when the suction nozzle 2 is moved forward.

The suction nozzle 2 is partially supported for reciprocating movement over the .Bodenfläche 12 by wheels 13, which in suitable Bores in the rear of the side walls 8 and 9 are fastened by screws 14 and clamping nuts 15 and it is the Allow the operator to easily move the vacuum cleaner 1 over the floor surface 12. In addition, the wheels deliver a convenient axis of rotation of the nozzle 2 for creating clearance over obstacles,

7ie one out! '' Ig. 3 recognizes is a suitable brush core in suitable bores in the side walls 8 and 9, for example supported by pin-like bearings 17 and 1δ, which are in the core are embedded.

The tufts of bristles 19 are embedded in the core 16 in the form of a plurality of helical rows. TSs are six tufts of bristles in the embodiment shown. λ

The tufts 19 form a brush, which dust and dirt sweeps from the floor surface 12 into a suitable suction chamber 20 which is formed by a partition wall 21 which extends extends downward in the housing 7 behind the brush. The, / and 21 ends in an edge 22 above the floor surface the brush. Dust and dirt is removed from the floor surface 12 by the brush, enters the suction chamber 20, moves through the suction tube 6 and enters the container 3.

The reproduced suction nozzle 2 produces a better effect because of the bristles used. As can be seen in particular from Figures 3> 4 and 5 are the tufts of bristles

19 so mounted in the brush core 16 that it has a Zinke1 form a radial direction and also run at an angle to the core circumferential surface, Fig. 4 shows the effect of Tufts 19 extend over surface 12 during free counterclockwise rotation the tufts 23, which touch the bottom surface 12 downwards, so that they are on the surface slightly in front of a grab vertical plane 24, which contains the core longitudinal axis, v / hen the suction nozzle 2 moves forward, press the tufts 23 against the bottom surface 12 and are suddenly released backwards so that a snapping or sweeping effect is exerted on the dust, thereby inevitably all dust and dirt particles 25 in the eye hammer

20 arrive, as FIG. 5 indicates.

Because the brush is located in its own separate chamber 26 and relatively spaced from the suction flow seated in the chamber 20, the action of the brush sweeps the deaf from the front air flow path directly into the path at the narrow opening to chamber 20. Us is therefore on the brush does not require any actual vacuum, and the main air flow is restricted to the narrow slot 27.

The off-center, angled brush tufts according to FIGS. 4 and 5 produce an overflow rotation of the brush relative to the floor surface 12. This creates a self-propulsion system, which difficult material, such as sawdust and can carry away hair.

The suction nozzle 2 according to the invention can also be equipped with a

Bare vacuum devices other than that The reproduced vacuum cleaner embodiment is used, for example also in vacuum cleaners with a flexible suction tube, various canisters, vacuum cleaners, central system vacuum cleaners and the same.

The invention thus provides a novel system for removing dust and dirt from a carpet paved or smooth floor proposed. By using of the off-center bristles in the correct arrangement in a suitable nozzle, one obtains a substantial better suction.
