CARPET SWEEPER

The invention relates to a carpet sweeper with one on the side Running wheels, manually movable by means of a swiveling handle bar, a housing mounted transversely in it, Rotary brush driven by the wheels and fold-out Dust containers.

The well-known carpet sweepers have disc-like running wheels, which are made of elastic, rubber-like material to dampen noise. However, this has the disadvantage that both the treated carpets, as well as the running wheels are exposed to heavy wear and tear and the running wheels are also exposed deform slightly transversely to the direction of movement. If the Impellers to avoid this disadvantage from one essentially are made of rigid material, the result is a relatively hard, noisy run. .

The object of the invention is now to provide an improved carpet sweeper to create that avoids the previous disadvantages and a smooth, quiet driving style with little Abrasive wear of the running wheels and the carpet connects and also allows the distance between the housing and the rotary brush on the carpet surface directly depending on to vary the pressure exerted on the handlebar.

The invention accordingly relates to a carpet sweeper with a wheel that has been running on since Liehen, by means of a swiveling] handle bar manually movable.Housing, one

in it transversely mounted by the running wheels> driven rotating brush and fold-out dust containers, characterized in that that the running wheels are designed as one-piece spoked wheels made of wear-resistant, semi-hard elastomers, their radial spokes extending from the hub in radial Direction, but not laterally deformable.

According to a preferred embodiment "sweet a ^z 8XE spokes of the wheels, a plate-like form with a sufficient to prevent transverse deformations transverse width, but sufficiently thin in the plane of cross-section.

According to the invention, the impellers can be maintained its low-noise run made of a significantly more abrasion-resistant material, whereby the plate-like ' Training the spokes on the one hand a sufficient stabilization against transverse deformation achieved and on the other hand a adjustable elastic by the pressure exerted on the handlebar Allows deformation of the spokes in the radial direction will. As a result, the housing and the rotary brush are moved closer to the carpet surface when the pressure is stronger, see above that the rotary brush deeper between the pile threads of the carpet penetrates.

In the following the invention will be described with reference to the accompanying drawings Drawings explained further. Show it:

Fig. 1 is a perspective view of a preferred embodiment of the carpet sweeper and

FIG. 2 shows a side view of the carpet sweeper according to FIG partially broken abutment edge.

The carpet sweeper shown in Figs. 1 and 2 has a substantially rectangular housing 1 with a domed top view Upper side, one in the middle sunk into this Handle tangennut 50, a laterally recessed adjusting lever groove 51 and a grip groove on the other side

009850/1329 ^

In the middle of the handle bar groove 50, a handle bar 2 is hinged, by means of which the housing can be moved back and forth on a carpet by a standing user. That Housing 1 consists of light, thin plastic walls and is open at the bottom. In the middle, a rotary brush 3 is rotatably mounted in the outer side walls 7 of the housing 1. The housing 1 runs on running wheels 4 which are arranged laterally in pairs one behind the other and also via a transmission wheel 5 turn the rotary brush 3 so that it opens picks up dust and dirt particles lying on the floor and puts them in the fold-out dust container in the housing 17b spins. At the lower outer edge of the housing 1 is a Bracket web 8-1 with a bumper 82 made of a shock-absorbing Material, such as rubber attached.

The running wheels 4 are made in one piece from an abrasion-resistant elastomer worked and have a hub 4b, from this radially outwardly extending spokes 4a and an outer running surface. The spokes 4a have a plate-like shape with a shape sufficient to prevent undesired transverse deformations Transverse width, but sufficiently small in the plane of the wheel, so that it is sufficient for radial deformation Have flexibility. The wheels 4 can be on their tread also be finely fluted or roughened.
