Abstract
Abstract The sweeping machine is fitted with a roller brush, whereby the lateralroller mountings of the sweeping machine cover the roller body and its axially extended retaining profiles for the brush units.
In order to effect and thereby simplify the replacement of brush units without removal of the entire roller brush, the sweeping machine is constructed such that the retaining profiles (1) feature an open construction radially toward the exterior, at the most according to the length of a brush unit (3) in at least one lateral zone of the roller body (2). The brush units (3) in this location are arranged such that they are secured radially by at least one retaining element (4) that surrounds all of the brush units (3).
In order to effect and thereby simplify the replacement of brush units without removal of the entire roller brush, the sweeping machine is constructed such that the retaining profiles (1) feature an open construction radially toward the exterior, at the most according to the length of a brush unit (3) in at least one lateral zone of the roller body (2).

Description

Roller Brush for a Sweeping Machine The invention relates to a roller brush for a sweeping machine, whereby the lateral roller mountings of the sweeping machine cover the roller body with its brush unit retaining profiles that extend in an axial direction and a plurality of brush units are arranged one after the other in the retaining profiles.
Roller brushes for sweeping machines~of the above-mentioned type, are known.
The replacement of brush units, with which the roller body is fitted, is especially difficult, because the brush units cannot simply be laterally removed from the retaining profiles, since the roller mountings of the sweeping machine are in the way, i.e. the normal removal/insertion path for the brush units is blocked by the roller mountings. These machines, which are employed in the cleaning of vehicle routes, primarily in airports, require for replacement of worn brush units the removal of the entire brush body from the sweeping machine~ only after which the removal of worn and the fitting of new brush units, can be carried out. Furthermore, af~er removal of the roller brush, the retrieval of certain securing elements is necessary, which elements hold entire rows of brush units in their retaining profiles. The retaining profiles have the form of cross-sectionally u-shaped longditudinal strips, with which the entire roller body is fitted and which remain fixed to the roller body. The cross-sectionally u-shaped retaining profiles feature at their free shank ends inwardly-oriented elbows, so that by means of these flanges, the inserted brush units are radially secured in the retaining profiles.
The invention, therefore, addresses the problem of improYing a roller brush for a sweeping machine of the type first mentioned such that the fitting of the roller brush with brush units, or, rather the replacement of such brush units is unhampered by the lateral roller mountings of th~ sweeping machine that block off the insertion channels, without necessitating the removal of the entire roller brush from the sweeping machine in question, the axis length of which can be up to 4 mO

The solution provided by the invention with a roller brush of the type first mentioned owes to the distinguishing features given in the description of the main claim. Advantageous developments and practical embodiments suggest themselves in the sub claims. From GB-PS 736 326 is known a roller brush with an open recess at the end of a narrow insertion slot for a length of brush elements; however, apart from the fact that this invention relates only to a roller brush for a small household sweeping machine, this open recess dictates that the length of brush element be extremely elastic, and therefore capable of being removed from or inserted into the recess, which is shorter than the overall length of the brush element.
The basis of the invention, that is, that the retaining profile should have an open design in the lateral zone being considered, implies simply that in this zone, the inwardly-oriented elbows are not present, or rather, have been removed, so that the brush units arranged in this zone rest freely in the retaining profiles and can therefore be easily removed. Because, however, the brush units arranged in this zGne must be secured, at least one retaining element has been included that surrounds all of the brush units, which retaining element radially retains the brush units. With respect to length, the open area of each retaining profile may be kept slightly shorter than the length of a brush unit, whereby the one end of the brush units is already secured by the elbows that begin at that point. Consequently~ it is necessary for the elbow to have a slight overlap of between 20 and 30 mm, in order to provide a stop for the brush unit in question. Because the several brush units Iying one after the other in the retaining profiles are generally ca. 400 mm in length, the brush unit in question can simply be tipped out from underneath the relatively short overlap of the elbow. At the other end of the brush units inserted in this removal area is arranged the retaining element, which in a practical embodiment advantageously assumes the ~orm of a securing ring that overlaps the ends of the brush units, this securing ring being arranged on the roller body such that it can be removed. This securing ring fulfils the same role as the flange overlap at the other ends.
In order at any one time to be able to remove the entire row of brush units

Because the several brush units Iying one after the other in the retaining profiles are generally ca. 400 mm in length, the brush unit in question can simply be tipped out from underneath the relatively short overlap of the elbow. At the other end of the brush units inserted in this removal area is arranged the retaining element, which in a practical embodiment advantageously assumes the ~orm of a securing ring that overlaps the ends of the brush units, this securing ring being arranged on the roller body such that it can be removed. This securing ring fulfils the same role as the flange overlap at the other ends.
In order at any one time to be able to remove the entire row of brush units
-3~ 980`7 from their retaining profile, it is merely necessary to loosen this securing ring and withdraw it ~rom ;ts ~verlapp;ng position, wh;ch is very simple, and then, as has already been mentioned, the first brush unit is withdrawn from the removal area, or from the open zone of the retaining profile. The other brush units remaining in the retaining profile are slid one after the other into the removal position, and similarly retrieved from this location.
The process of replacing the brush units occurs in the same way, but in reverse order, whereby lastly the securing ring is held by suitable means in ;ts ~ixing position on the roller body. Because there occurs considerable centrifugal force during the rotat;on of such a roller brush, ;t is advantageous to construct the roller brush in such a way that the brush units installed in the radially open zone of the retaining profiles are secured radially in the middle by means of another retaining element. This retaining element acts very much like a clamp, wh;ch must be opened at least at one point, so that it may be placed against or withdrawn from the roller brush.
The roller brush according to the invention is further described by means of the attached drawings of the embodiments o~ the invention.

Schematically described are:
Fig. 1 a sweeping machine with a roller brush, from the side;
fig. 2 a partial section through the roller brush along line II-II
in Fig. 3;
Fig. 3 a partial longditudinal section through the roller brush along line III-III according to Fig. 2, Fig. 4 a longditudinal section through the roller brush with a lateral roller mounting;
Fig. 5 a top view of the retaining profile of the roller brush and Fig. 6 a special embodiment of the securing ring.
In Fig. 1, the sweeping machine 8, in highly schematic presentation, features frontally located roller mountings 9, between which, similarl~
~269~3~7 .. . ..
recognizable, the roller brush 10 is arranged so that it can turn and be powered in a suitable manner. Further evident in Fig. 17 iS that the roller mountings 9 have been designed so that, apart from brush 11, the roller body 2 with retaining profile 1, and its complement is fully covered as viewed from the side, so that there is no possibility of laterally removing the brush units 3 situated in the retaining profile 3. As can be seen in Fig.
2, the retaining profiles 1 have a somewhat u-shaped cross-section, whereby at the free shank ends, elbows 7, oriented toward the inside, have been installed, which elbows 7 prevent a radial falling or flying out of the brush units 3. In each of the retaining profiles 1, which are fixed with screw connections 12 to the cylindrical roller body 2, sit brush units serially in a row according to the length of the entire roller brush, for example, ten brush units 3.
It can be seen in Figs. 4 and 5 that the retaining profiles 1 feature an open construction radially toward the outside in at least one lateral zone of the roller body 2 at the most according to the length L of a brush unit 3, i.e., the elbows 7 are not present in this 'removal zone'. Instead of this arrangement, a retaining element 4 for the brush units located in this zone is situated at the end of the roller body 2, which retaining element 4 secures these brush units 3 in the radial direction, so that these brush units 3 are securely held to the roller body 2. In a practical embodiment, and as shown in Fig. 4, the retaining element 4 assumes the form of a securing ring 5 that overlaps the ends 3' of the brush units 3, and this securing ring 5 is positioned on the roller body 2 such that it can be removed. Apart from the fact that one could secure the other ends 3" with a circumferential band or clamp, the embodiment represented in Fig. 4, 5 is preferred, i.e., the elbows 7 with their end 7' overlap by 20 to 30 mm the brush units 3 or rather their ends 3", whereby the overlapping ends 7' of the right-angular profiles 7 excercise the securing function. Between the end of the roller body 2 and the lateral roller mounting 9, there is enough space to permit, after removal from the roller body 2, a slight lateral shifting of the ring 5. In this way, the brush units 3 can be easily removed from the retaining profiles after ~2~g~07 tipping or lateral shifting. During centrifugal loading, in order to prevent the bending and loosening from their end mountings (~ing 5) and angled profile ends, of the brush units 3 located ;n the removal zone, an additional, centrally situated retaining element 6 may be included, that assumes the role of a transformational clamp and is so designed that it can be slid laterally over the roller body with its retaining profile-and brush units and securely locked.
Basically, the securing ring 5 can be constructed in two parts that come together (see Fig. 6), which may be required if there is too little room for a lateral sliding of the ring toward the arrows as indicated in Fig. 4.
The ring halves could be closed together at a connection point. This two-part arrangement ensures that the securing ring can rest in its lateral position against the roller body 2 or the brush units 3 located in the removal zone.
