Brush, in particular, for

Cleaning of rough surfaces such as carpets, upholstered furniture and the like.

With the brushes known so far for cleaning rough surfaces such as carpets, upholstery and the like, stepped the disadvantage that with the movements of the brush not all impurities are removed and thus the ones to be brushed Surface could not be completely cleaned · This is due to the fact that certain shapes, such as In particular, threads, flakes and the like, adhered so firmly to the rough surface that the tufts of bristles did not or only after relatively long brushing process could be removed from the surface to be cleaned. These kachteile also showed up especially when the brush has been connected to a suction device, e.g. a vacuum cleaner.

Vacuum cleaner brushes have become known in which the tufts of bristles are inclined within the bristle holder on the brush housing and the bristle carriers are resiliently arranged in guides of the burst-tight housing. With these well-known Brushes, however, only a single row of tufts of bristles is provided, which is inclined. In contrast, two types of tufts of bristles are provided in the subject of the application: One is perpendicular tufts of bristles arranged towards the treatment surface and, on the other hand, obliquely directed tufts of bristles. Different between these The suction slot is located on the stored tufts of bristles.

Due to this special design of the vacuum cleaner brush has a beneficial effect when treating rough surfaces

achieved »by the differently positioned tufts of bristles in the Cleaning and brushing process to take over different punctures to have. This eliminates certain impurities that are calibrated on the Carpet are located, from the vertically arranged tufts of bristles ^ loosened and sucked off by the air flow of the suction slot You have inclined tufts of bristles against the vertical tufts of bristles also fulfill an additional task As a result of their inclination, they should intervene like a hook in contaminants that have a linear expansion, such as Threads and the like that get caught in the carpet fabric and confused it, and to a certain extent pulled it out of the carpet surface, loosened it up and thus the airflow of the suction slot must be made accessible, so that these contaminants, which are known to be difficult to suck off, can also enter the suction slot.

Such an effect is provided by the vacuum cleaner brush known institutions not realized. This is due to the fact that only a single, inclined row of tufts of bristles is present · Another disadvantage of the known devices is that behind the tufts of bristles, several bulbs are arranged. This has the disadvantage with the reciprocating movements of the vacuum cleaner brush that it removes the impurities roll and iron into the surface to be treated, so that the tufts of bristles are forced to remove these ironed-in impurities loosen again to feed them to the vacuum cleaner opening.

The subject of the application is such rolling roles not present at all, but the whole brush rests in the first place Line on tufts of bristles, each row of tufts of bristles, be it the vertical or the oblique, strives to remove the impurities to loosen up the carpet and thus the suction air—

In other known devices, which also only have a single row of brushes, are also on the two narrow sides Sliding shoes are provided which, because of their narrow shape, press themselves into the surface of the carpet to be treated, so that not only are traces left in the carpet, but also the correct position of the lower ends of the The tuft of bristles on the carpet hair is subject to fluctuations, depending on how strong the operator touches the mouthpiece on the carpet.

These disadvantages become in the subject matter of the invention avoided not just a single row of tufts of bristles, but several are available, of which the greater part is provided with tufts of bristles that run perpendicular to the surface of the carpet is. Another compensation is the subject of the registration by arranging a front glide achuhea with a wide area created that extends over the entire length of the vacuum cleaner brush extends, and which is drawn down so deep that it is flush with the lower ends of the inclined tufts of bristles. The rear bulge is deliberately not drawn so deep down because the two perpendicular ones are in its vicinity Are rows of tufts of bristles provided that are sufficient? about one To absorb part of the vacuum cleaner pressure. You can see that with this very special construction, the vacuum cleaner brush despite Arrangement of inclined tufts of bristles quite systematically and consciously for an exact weight distribution during the vacuum cleaner movements care is taken so that the desired cleaning of the carpet actually occurs.

Ea brushes are also known in which, although a obliquely directed single row of tufts of bristles is provided,

However, this known device also has the disadvantage that for the purpose of guiding the device over the surface to be cleaned special leadership roles are necessary. Apart from this, the operator needs to use this known vacuum cleaner brush use a very special skill. So it is necessary to turn the mouthpiece a little forward and then to loosen the thread remnants on the carpet. It iat novh another option suggested; in which the rollers are resiliently mounted in the nozzle body. In this case, ee be possible the brush. ·; without tilting it, bring it up to the area to be treated. But here, too, one is in highly dependent on the skill of the operator. This must exert a very specific pressure on the nozzle body. Of course, it cannot be avoided here, that the pressure is either too strong or too weak, so that the desired effect does not occur or occurs only imperfectly.

In order to eliminate these disadvantages, according to the invention, a part of the bristle tufts or all of the bristle tufts are used obliquely, seen in the direction of movement of the brush, inclined from the top front to the bottom back within a bristle carrier or stored within a plurality of bristle carriers on the brush housing, the bristle carrier (s) within guides of the Brush housing are resiliently guided. This arrangement and storage of tufts of bristles achieves that When the brush moves backwards, the tufts of bristles as a result of the inclination, somewhat like the prongs of a rake, also are mounted obliquely to the surface to be raked, into the impurities adhering to the surface to be cleaned to a certain extent hook and thereby lift these impurities from the surface and loosen them.

Able to relatively quickly this otherwise firmly adhering Brushing impurities onto a shovel, for example, and thus removing them.

In a special embodiment of the invention, it is expedient to arrange rows of tufts of bristles on the brush, of which the rear or the rear rows are fixed to the brush housing are arranged, while one or more rows of tufts of bristles arranged at the front of the brush, as described above, at an angle and are spring-mounted in the brush housing. Here, between the stationary rows of tufts of bristles on the one hand and the inclined and beveled rows of tufts of bristles on the other arranged a suction slide. Through this design The brush eliminates the need to use a special shovel, rather it is sufficient to move the brush back and forth over the too cleaning surface, with the inclined and cushioned tufts of bristles during the backward movements of the brush have the scratching effect and loosen certain stubborn dirt from the rough surface. Purch this easing the impurities offer the suction air flow a better surface to attack, so that it can pass through the behind the inclined bristles arranged suction slot can be easily sucked off. In the case of the brushing process, it is also particularly beneficial that it consists of back and forth movements, because the brushes follow the backward movement a forward movement takes place, during which impurities possibly still adhering to the tufts of bristles as a result of the scratching process are released and thereby free of interference from the air flow can be discharged,

The loosening process, reminiscent of a raking or scratching effect, is practiced by inclined tufts of borate, on the other hand, because they are not rigid prongs or pins, but flexible tufts of bristles are not rigidly mounted in the brush housing »but resiliently resilient in the longitudinal direction of the bristles. In this way, the pressure exerted by these inclined tufts of bristles on the surface to be cleaned can be adjusted and the desired loosening effect can be achieved without, on the other hand, the rough surface to be cleaned, in particular the carpet or the upholstery, from being too hard and sharp brushing will wear out prematurely. This is important because the inclined bristles are expediently made relatively stiff.

The brush housing 1 has an elongated recess 5 on the underside in the vicinity of the rear Ki, which recess serves to receive a tuft carrier 6. Within this bristle tuft carrier 6, two bristle tuft rails T, B provided with bristles are mounted. A suction channel 9 leads from the suction nozzle 2 of the brush to the suction opening 10. In front of this suction opening 10, a bristle bar 13 is mounted in the wall 11 of the brush housing 1 within a slot guide 12 so as to be easily displaceable. The slot guide 12 and thus also the bristle ens chi ene 13 are inclined obliquely from the front top to the rear bottom so that the tufts of bristles 14 mounted in this rail 13 also assume a corresponding inclined position.

The wall 11 is formed downwards to form a guide shoe 15, so that the brush when placed on the surface to be cleaned, in particular the carpet 16 to be cleaned, on the Front edge rests on the shoe 15 while in the rear Part of the two tufted bristle rails 7 »8 firmly arranged in the housing rest on the carpet 16.

During the cleaning process, when moving backwards in the direction of arrow 17, the inclined position of the tufts of bristles 14 exerts a scratching effect on those contaminants that are firmly attached to the carpet, which loosens these contaminants, and under certain circumstances even raises them slightly so that the air flow sucks these parts through the channel 9 into the suction nozzle 2. If any contaminants get stuck below the bristles 14, when the brush moves forwards against the direction of the arrow 17, these parts are released again and are also sucked off by the air flow «
