Description

Technical area

The present invention relates in one aspect to a segment, in particular a brushing, cleaning, grinding or polishing segment for detachable arrangement on a circular support of a plate, in particular for the formation of a plate plate or a cleaning, grinding or polishing plate. According to a further aspect, the invention further relates to a carrier of a Tellererbesens and a correspondingly equipped disc brush, which has such a carrier with a plurality of segments disposed thereon, such as brushing or polishing segments.

background

The use of so-called plate brushes is well known for the cleaning of paved areas. Common sweeping and cleaning machines or devices have a motor driven and correspondingly rotatable head, i. a drive train on which a support for the disc brush is arranged rotationally fixed. Common disc brushes have a disc-shaped plate body on which a plurality of bristles are arranged, which faces away from the plate body with its free end, typically approximately axially relative to the axis of rotation of the plate body, or axially and radially outwardly inclined at a predetermined angle are.

From the US 3,766,589 A For example, a disc brush with an upper and a lower plate is known, which are interconnected by means of several bolts. Between the plates, individual, each equipped with bristles segment body can be arranged. By tightening the bolts, those bodies can be clamped between the plates. In such a solution, although individual equipped with bristles segments of a Tellerbesens can be replaced as needed. For the replacement of segments, however, the aid of cooperating with the bolt tools is required. Thus, under certain circumstances, the lower plate must be completely removed and dismantled, which is conveniently only on a completely dismantled by a sweeping or cleaning machine disc brushes should be possible.

In contrast, the present invention seeks to provide an improved plate to form a plate plate or to form a cleaning, grinding or polishing plate and provided for this purpose segments that are as simple and intuitive as possible mounted on the plate and interchangeable if necessary. The assembly and / or disassembly of individual segments on or from a carrier of the plate plate should be possible without tools, so without the aid of fastening tools. The segments and the carrier corresponding therewith should have the simplest possible and robust construction. They should be as simple and inexpensive to produce. According to another aspect, the segments should have an improved life cycle assessment. They should be manufacturable resource-friendly.

Advantageous embodiments

This object is achieved with a segment according to the independent claim 1 as well as with a carrier for forming a pan plate or for forming a cleaning, grinding or polishing plate according to claim 14. Advantageous embodiments are each the subject of dependent claims.

The inventively provided segment is configured for releasable arrangement on a circular, typically disc-like carrier of a plate plate or a cleaning, grinding or polishing plate and provided for this purpose. The segment has a segment body. If the segment is designed as a brush segment to form a plate plate projecting from the underside of several bristles or bristle tufts. In an alternative embodiment of the segment, for example to form a cleaning, grinding or polishing plate or a corresponding disc is on the underside of the segment body an abrasive Grain, and / or a fiber structure, for example. In the form of a fabric or a non-woven arranged.

The segment body has, based on a circular geometry of the carrier, two opposite side edges, which limit the segment body in the circumferential direction. The segment body may have a part-circular geometry. A plurality of circumferentially adjacent to each other arranged segment body can complement each other to a full circle or to a circular ring whose radius substantially corresponds to the radius and the geometry of the wearer of the plate plate or the cleaning, grinding or polishing plate.

The side edges of the segment body may, in relation to the circular geometry or pitch circle geometry, of the segment body extend in the radial direction. Other extensions or, for example, a substantially rectangular geometry of the side edges of the segment body are likewise conceivable in principle.

At an upper side of the segment body, which is remote from the bottom, at least one longitudinal segment guide is arranged. This is designed to cooperate with at least one corresponding thereto designed and arranged on an underside of the carrier carrier guide for the arrangement or attachment of the segment body on the carrier. An elongated segment guide and a carrier guide designed to correspond thereto are translationally displaceable into one another and to one another in the longitudinal direction of the segment guide and carrier guide.

For an arrangement and attachment to the carrier, it is thus necessary and sufficient to align the provided on its top segment guide to the carrier guide and to move the segment guide in the longitudinal direction relative to the carrier guide translational. The segment guide and the carrier guide have corresponding complementary, typically positively interlocking complementary profiles, by means of which can be realized as a result of longitudinal displacement of the segment body relative to the carrier guide a positive connection of segment body and carrier.

The at least one segment guide on the upper side of the segment body is arranged, with respect to the circumferential direction, between the side edges of the segment body. That is, the segment guide is located outside the side edges of the segment body. It is preferably located at a predetermined distance from the side edges of the segment body.

The segment bodies can be fastened on the underside of the carrier solely by a radially inwardly directed displacement movement. The carrier guide provided at least on one underside of the carrier may define a receptacle for one of the segments. Individual recordings on the underside of the carrier can only be designed virtually and as imaginary pictures, so to speak. They are ultimately defined by the position and the volume of the segment body when they are arranged and fixed to the carrier. The carrier may have on its underside but also several, with the geometry of the individual segments corresponding and existing real, for example, by radially extending partitions separated from each other receptacles for the individual segment body.

The provided for each segment shots on the underside of the carrier are in any case accessible from the outside radially. The receptacles for the segment body are thus open and barrier-free on the underside of the carrier, viewed radially outwards. It is basically possible that the underside of the carrier is completely flat and flat except for the carrier guides. Only the carrier guides can be formed as depressions or elevations on the otherwise plan designed underside of the carrier.

Due to the radially outer to radially inwardly directed assembly of the brush segments on the carrier a particularly intuitive and easy-to-handle replacement of individual brush segments is provided on the carrier. This is made possible by the segment and carrier guides which correspond to one another at the top side of the segments and by the underside of the carrier, wherein at least one guide of a pair formed by a segment and carrier guides is elongated and an insertion and removal line is provided by the longitudinal extension / or fixing direction pretends.

According to a development, the at least one segment guide extends parallel to an imaginary center line extending in the radial direction and centrally between the side edges of the segment. The imaginary center line can form, for example, an axis of symmetry of the segment body. The segment body may be formed with respect to its outer contour with respect to the imaginary center line mirror symmetry. The at least one segment guide can also coincide with the center line and, to that extent, extend strictly radially inwards to the imaginary circle center of the segment body or of the circular carrier.

But it can also be provided an offset of the segment guide to the center line. An offset to the center line segment guide preferably extends substantially parallel to the radially extending center line. A radially inward extension of the segment guide consequently has no point of intersection with the center of the circle of the carrier or with the imaginary circle center of the relevant segment body.

The radially parallel alignment of the segment guide and typically also the corresponding radially parallel alignment of the carrier guide allow a radially outwardly to radially inwardly directed fastening of individual brush segments on the carrier of the plate template. It can be provided in particular for a fastening and arrangement of the brush segments on the carrier of the plate plate to arrange them directly radially outside and below the carrier and bring about only by a radially inwardly directed displacement of individual brush segments relative to the carrier an arrangement and attachment of the brush segments on the carrier.

According to one embodiment, the at least one segment guide on the upper side of the segment body has a T-shaped, L-shaped or dovetail-shaped groove on the upper side of the segmented body. Alternatively it can be provided that the at least one segment guide has a cross-sectionally T-, L- or dovetail-shaped projection which protrudes from the upper side of the segment body. The segment body and its upper side can be substantially flat and with the exception of the segment guide provided therefor just be designed. By means of cross-sectional T, L or dovetail-shaped profile structures, the at least one segment body can be arranged to be displaceable in the radial direction on the carrier.

A T-, L- or dovetail-shaped cross-sectional profile of the segment guide can provide a form-fitting connection, which acts in the axial direction and in the circumferential direction, for the segment body on the carrier. With the axial direction in this case an extension parallel to the axis of rotation of the carrier of the Tellererbesens is meant.

According to a further embodiment, at least two segment guides extending parallel to one another and spaced apart in the circumferential direction are arranged on the upper side of the segment body. The at least two mutually parallel segment guides are typically arranged equidistant from the imaginary center line.

In particular, in the case of two segment guides, these can have mirror-symmetrical L-shaped cross-sectional profiles, in order to engage in a form-fitting manner with the L-shaped cross-sectional profiles of the carrier guides correspondingly designed or complementarily configured on the underside of the carrier. L-shaped cross-sectional profiles of the segment guide and / or the carrier guide can be particularly easy to manufacture, especially in an injection molding process, realize. Also, by means of two mutually parallel segment guides a multiple and thus more secure fixation of the segment body carried on the carrier.

According to a further embodiment, a locking element is arranged on the upper side of the segment body, which is designed to cooperate with a provided on the underside of the carrier counter-latching element to fix the segment body radially on the carrier. At least one of locking element and counter-locking element is axially movable between a locking position and a release position.

For example, in a final assembly position, the segment body is moved along the longitudinal direction of the engaging segment guides and carrier guides spent on the underside of the carrier, the locking element comes with reaching the final assembly position with the support side provided counter-locking element into engagement. The locking element, for example, during a mounting process of the segment body on the carrier against a restoring force are stretched elastically, so that the locking element springs back on reaching the final assembly position of the segment body on the carrier in an initial position and this fixes the segment body radially on the carrier and secured as a result of engagement with the counter-locking element.

For releasing the radial connection of the brush segment and disc brush, it may be provided to elastically deform either the latching element or the counter-latching element at least for a short time, so that the counter-latching element or the latching element is released. Then the segment body, thus the entire brush segment, from a radially inner final assembly position radially outward along the geometry of the segment guide and carrier guide is displaced until the segment guide and the carrier guide disengage.

According to a further embodiment, the latching element has an axially elastic and extending in the radial direction latching tongue whose radially outward edge cooperates with a corresponding thereto formed stop on the underside of the carrier. The latching tongue can in particular protrude by a predetermined amount from the top of the otherwise planar designed segment body, so that it can be pressed by a predetermined amount in the axial direction movable, in particular in the direction of the top of the segment body.

For example, the stop on the underside of the carrier may protrude axially from the otherwise substantially flat underside of the carrier. The stopper may extend axially and circumferentially on the underside of the carrier and accordingly protrude from the underside of the carrier. But it is also conceivable that the stop is designed in the form of an axial recess on the underside of the carrier. The recess may in particular be dimensioned such that it can receive the spring-loaded latching tongue. For example, if the latch reaches the area of the stop, It can relax in the axial direction into its initial position and cooperate insofar with a radially outer and radially outwardly facing edge with a radially inwardly facing stop of the carrier. That mutual contact position of locking tongue edge and stop of the carrier leads to a radial securing of the segment body, thus the entire segment on the carrier of the plate template. The segment or the segment body is secured against a radially outward displacement on the carrier.

According to a further embodiment, the counter-locking element has an axial passage opening in the carrier, the opening boundary, in particular its radially outer opening boundary or the inner wall forms on the underside of the carrier one or the stop for the locking element. To carry out the counter-latching element as an axial passage opening also has the advantage that the latching element or its latching tongue snaps with a final assembly position of the segment body on the carrier from below into the passage opening and comes to lie in the passage opening. The axial passage opening is thus accessible from above, so that, for example, for releasing a segment body which abutting the underside of the passage opening latching tongue through the passage opening against a restoring force of the latching tongue from the detent position into the release position can be transferred.

With individual passage openings in the carrier not only the total weight of the carrier can be reduced. The passage openings at the same time form a counter-latching element cooperating with the latching element, which also forms an intuitive and easy accessibility for the latching element engaged with the counter-latching element.

According to a further embodiment of the segment, the detent element is arranged in the circumferential direction between the two segment guides. The locking element can be located in particular approximately in the middle between the segment guides. An arrangement of the locking element between the segment guides allows a particularly compact design of all engaging with the underside of the carrier components of the brush segment.

According to a development, it is further provided that the latching element and the at least one segment guide are formed in one piece or in one piece. Similarly, the latching element with two segment guides may be formed integrally or in one piece. A close-spaced arrangement of segment guides and locking element allows a particularly compact design of a one-piece holding part, which unites the segment guides and the locking element in a single component.

Due to the mechanical connection with the carrier to be realized by the segment guides and the latching element, higher requirements with regard to manufacturing and component tolerances have to be met for the latching element and the at least one, preferably for both segment guides, than is the case for other areas of the segmented body. By the latching element is arranged close to the at least one segment guide or the latching element between two segment guides, a particularly compact design of the latching element and the segment guide uniting holding member can be realized at the top of the segment body. This can prove advantageous in terms of lower production costs.

According to a development it is further provided that the segment body is designed in several parts. It has a lower base part and an upper holding part, which are interconnected. Base part and holding part are typically positively connected to each other, for example, clipped together. Such form-fitting connections prove to be manufacturing and assembly technically particularly practical and are easy to implement. Furthermore, it is conceivable to use an upper holding part several times for a plurality of base parts, which naturally are subject to comparatively high wear according to the bristles arranged thereon. The multicomponent structure of the segment body fundamentally enables a resource-saving and cost-saving, at least partial recycling of used segment bodies.

According to a further embodiment, the bristles, the abrasive grain and / or the fiber structure are arranged on the base part of the brush segment and the at least one segment guide is arranged on the holding part. Both are preferred Segment guides, if present, arranged on the holding part. In a one-piece or one-piece design of segment guides and locking element is of course also provided that the locking element is also arranged on the holding part. Thus, all components of the brush segment which engage with the underside of the carrier in a form-fitting manner can be arranged solely on the holding part and provided thereon.

The holding part may have a particularly compact design. Due to its mechanical interaction and its positive engagement with the at least one carrier guide and the counter-locking element, the holding part should comply with lower manufacturing tolerances than the base part. Consequently, larger manufacturing and assembly tolerances are allowed for the base part as for the holding part. In this way, the base part can be made of a less expensive material than the holding part, which is present in lesser quality or purity. Also, the base part may have higher manufacturing tolerances than the holding part.

According to a development, it is further provided that the base part has a plurality of bristle openings accessible from above for receiving bristles or bristle tufts. The holding part extends in its mounting position on the base part over all bristle openings. It may in this case form an upper closure lid for the base part. The base part may, in particular, have a far-reaching base area provided with a plurality of bristle openings.

Approximately U-shaped bent bristles or bristle tufts can be inserted through downwardly projecting bristle ends through individual bristle openings from above, so that the free ends of the U-shaped bent bristles or bristle tufts protrude downwards from the base part, thus protruding from the bottom of the segment body and projecting therefrom , By the holding part at the same time acts as a closure cover for the base part, it can prevent the bristles or bristle tufts from the bristle openings in a corresponding fixation on the base part. The holding part can, as it were, form an abutment for the U-shaped bent regions of the bristles or bristle tufts. The multi-part design and the subdivision of the segment body in a base part and in a holding part thus proves to be advantageous for the mounting and fixing of the bristles or bristle tufts on the segment body.

In this case, it can be provided, in particular, that the holding part and the base part can be connected to one another in a form-fitting manner, for example by being clipped together. It is also conceivable here that used brush segments are reprocessed by the holding part separated from the base part, torn bristles or bristle tufts are replaced on the base part and hereafter the holding part is again connected to the base part. Base part and / or holding part can in this respect also be repeatedly and bristles or bristle tufts fitted.

According to a further embodiment, at the outer edge of the holding part distributed, several downwardly extending to the base part locking members, for example in the form of locking lugs, which cooperate form-fitting with a formed on the edge of the base part counter-latching structure. The counter-latching structure can be formed for example in the form of a circumferential groove or a circumferential projection either on the inside or on the outside of a side wall of the base part. In principle, it is also conceivable that upwardly projecting latching members, for example in the form of individual latching noses, are arranged on the base part, while the holding part is configured with a form-fitting structure corresponding therewith, for example in the form of a circumferential groove or a corresponding projection. It is also conceivable that both the holding part and the base part are provided with locking members. Conversely, it is also conceivable that the base part with a plurality of latching members and the holding part are provided with a positive locking structure.

By means of latching lugs and a counter-latching structure on the holding part and on the base part, a positive connection of holding part and base part, for example in the form of a clip connection can be provided. This is particularly easy to implement in the manufacturing and assembly process of individual segment body, preferably without tools.

According to a further embodiment, the holding part and / or the base part are formed as a plastic injection-molded component. It can be provided in particular that both the holding part and the base part are made as plastic injection-molded components. For the holding part and for the base part in this case different plastics or plastic mixtures can be provided. The holding part typically has a higher value plastic than the base part. This is particularly advantageous in such embodiments, when both the segment guide or the segment guides and the latching element are integrated into the holding part. Recycled or recycled plastics or plastic granules may also be used for the base part up to a certain proportion. The manufacturing and production costs for the base part can be lowered in this way.

According to a further aspect, the invention further relates to a carrier for forming a plate plate or for forming a cleaning, grinding or polishing plate, to which a plurality of the previously described segments are detachably arranged and fixable. The carrier has a circular carrier disc, which is rotatably drivable with respect to a rotational axis on a sweeping, cleaning or polishing machine. At the bottom of the carrier disk or the carrier a plurality of receptacles for the brush segments described above are provided. The recordings adjoin one another in the circumferential direction of the carrier disk. They are bounded by imaginary side edges or margins formed by dividers.

The side edges of the receptacles provided on the underside of the carrier disk can extend in the radial direction, that is, from a radial outer edge of the carrier disk to the center of the carrier disk.

On the underside of the carrier disk and in the region of each (imaginary) receptacle, at least one longitudinally extended carrier guide corresponding to the segment guide of the segment body is provided. The carrier guide is located between the side edges of the respective recording. It is located in particular at a predetermined distance in the circumferential direction to the side edges of the respective recording. The at least one elongated carrier guide at the bottom the support disk is configured corresponding to or complementary to the segment guide on the upper side of the segment body. The carrier guide may be formed according to the cross-section segment guide. The carrier guide may have a cross-sectionally T-, L- or dovetail-shaped groove or a correspondingly configured projection on the underside of the carrier disk.

Because carrier guides are arranged only on the underside of the carrier, the receptacles provided for the segments remain freely accessible from the outside radially. This allows a particularly simple and intuitive attachment and arrangement of individual segments on the carrier.

According to a further embodiment, at least two mutually parallel and circumferentially spaced carrier guides are arranged on the underside of the carrier disc and in the region of each of the receptacles. Such a circumferentially spaced arrangement of two carrier guides allows an L-shaped cross-sectional geometry of the carrier guides, which are positively engageable with corresponding or complementary thereto designed L-shaped segment guides a respective segment body in such a way that the segment body is guided in the radial direction on the underside of the carrier until a final assembly position is reached, in which the latching element of the segment body cooperates with the counter-latching element of the carrier disc.

The carrier guides extend parallel to an imaginary, in the radial direction and centered between the side edges of the respective receiving center line of the respective recording. The imaginary center lines of the receptacle and the segment body can come to lie substantially overlapping one another when the segment body is introduced from radially outward into the receptacle on the underside of the carrier disk.

According to a further embodiment, the carrier disc, thus the carrier on a cooperating with the locking element of the brush segment counter-locking element. The counter-locking element can in particular as an axial passage opening be configured in the carrier or in the carrier disk. An opening boundary, in particular a radially outer side edge of the passage opening can form one or the stop for the latching element of the brush segment.

According to a further aspect, finally, a disc brush or a cleaning, grinding or polishing plate is provided for arrangement on a cleaning, sweeping or polishing machine, which has a previously described carrier and at least one segment arranged thereon.

Instead of a brush segment equipped with bristles, it is also conceivable that no bristles are arranged on the underside of the segment body, but only a cleaning structure reaching into contact position with a surface to be cleaned, for example in the form of a woven fabric, a knitted fabric or an abrasive grain. The arrangement of bristles projecting from the underside of the segment body is merely exemplary and in principle the segment body can also be designed as a segment of a grinding or polishing segment, the segment body having on its underside a grinding, polishing or abrasive surface.

The disc brush is basically both for use in road and pavement cleaning, a cleaning, grinding or polishing plate is preferably used for the areas of interior cleaning.

It should also be noted that all the features and advantages described in relation to the brush segment also apply in the same or analogous manner to the carrier of the plate and the plate broom; and vice versa.

Detailed description

In the Fig. 1 and 3 a with respect to a rotation axis 1 on a sweeping or cleaning machine rotatably storable plate brush 10 is shown. The disc brush 10 has a disc-like and circular support 12, on its underside 15 a plurality of receptacles 18 for each brush, cleaning, grinding or polishing segments are provided. A brush segment 40 is, for example, in FIG Fig. 5 presented with its individual parts. Instead of brush segments 40 provided with bristles 6 or bristle tufts, the circular brush 10 can also be configured equally with cleaning segments not shown here, on whose underside facing a surface to be machined or cleaned, instead of bristles, a grinding or cleaning pad is arranged or formed. The plate broom would then not designed as a broom but as a cleaning, grinding or polishing plate.

The individual brush segments 40, which can be arranged on the support 12 and are of widely identical design, each have a segment body 42, which is like a piece of cake or with respect to its opposite side edges 17, 19, as in FIG Fig. 10 For example, shown wedge-shaped. In Fig. 10 only a conceivable geometric configuration of a segment body 42 is shown. Advantageously, several, in the circumferential direction u adjacent to each other on the underside of the carrier 12 arranged segment body 42 complement each other to a full circle or a circular ring, as for example in Fig. 3 is shown. Here, a total of nine immediately adjacent in the circumferential direction u adjacent segment body 42 a closed circumferential ring, wherein the segment body 42 are not mutually, but only and exclusively on the underside 15 of the carrier 12 of the plate recess 10 are detachably arranged. The carrier 12 is configured as a circular or as an annular far-reaching flat carrier disk 14.

On the underside of the carrier 12, a plurality of receptacles 18, each for a segmented body 42, are formed. The receptacles 18 can adjoin one another directly in the circumferential direction. The receptacles 18 are directly radially accessible from the outside. That is, the receptacles 18 are viewed open in the radial direction outward and barrier-free, so that individual brush or cleaning segments 40 particularly simple and intuitive from radially outside to radially inside at the bottom of the carrier 12 in an in Fig. 1 shown final assembly position can be spent.

For a sliding movement and for a radial guidance of the segment body 42 on the support 12, both carrier side and segment body side are provided with each other corresponding or complementarily configured guides. In the present case, each of the receptacles 18 on the underside of the carrier 12 has two mutually parallel carrier guides 20, 22. The carrier guides are in this case, with respect to the circumferential direction u, offset from an imaginary center line 25 of the receptacle 18 offset and spaced therefrom.

The center line 25 extends centrally between the, relative to the circumferential direction (u) outer side edges 17, 19 of the receptacle 18. The center line 25 extends exactly in the radial direction (r), that is from the outer edge of the support disk 14 radially inwardly to the center 11. Corresponding to the two parallel carrier guides 20, 22, two likewise parallel aligned segment guides 50, 52 are provided on the upper side 48 of the segment body 42. The segment guide 50 can be brought into positive engagement with the carrier guide 20. The segment guide 52 is positively engageable with the carrier guide 22 designed to correspond thereto in a form-fitting manner.

At least one of carrier guides 20, 22 and segment guides 50, 52 has an elongated contour, so that the segment body 42 is linearly and translationally guided in the course of a radially inwardly directed assembly movement, until it has an in Fig. 1 indicated final assembly position reached. In principle, it is sufficient if only a carrier guide 20 or a segment guide 50 are arranged on the underside 15 of the carrier 12 and on the upper side 48 of the segment body 42. In this case, one of the carrier guide 20 or segment guide 50 is configured in the form of a T-shaped or dovetail-shaped groove, while the other of carrier guide 20 and segment guide 50 is configured in the form of a T-shaped or dovetail-shaped profile projection.

In the present exemplary embodiment, with two carrier guides provided on the carrier 12 each and two segment guides 50, 52 configured on the segment body 42, all carrier guides 20, 22 and segment guides 50, 52 are L-shaped in cross-section. The segment guides 50, 52 and the Carrier guides 20, 22 are designed as guide profiles or carrier profiles which project in cross-section L-shaped and project from the underside 15 or from the upper side 48, which engage in a form-fitting manner. The two carrier guides 20, 22 are symmetrical to each other. The same applies to the segment guides 50, 52. The segment guides 50, 52 come to lie between the legs of the carrier guides 20, 22. The free ends of the segment guides 50, 52 project L-shaped away from each other while the free ends of the support guides 20, 22 are L-shaped toward each other.

The provision of comparatively elongated guides on the underside 15 of the carrier 12 and on the upper side 48 of the segment body 42 proves to be particularly advantageous for the assembly process, than that with an already small radial overlap of a radially inner portion of the segment body 42 with a radially outer Section of the receptacle 18 is already a linear guide of the segment body 42 can be achieved on the support 12, long before the conically aligned side edges 47, 49 of the segment body 42 come into contact with circumferentially adjacent segment body. In this way, a particularly simple and intuitive insertion of the segment body 42 is provided in the receptacles 18 of the carrier 12. At least one of the guides 20, 22, 50, 52 advantageously has a longitudinal extent which is greater than half the radial extent of the relevant segment body 42.

On the upper side 48 of the segment body 42, a latching element 56 in the form of a latching tongue 57 is further formed. The latching element 56 is in the axial direction (z), that is perpendicular to the plane of the segment body 42 deformable. In the in the Fig. 2 and 6 reproduced representations, the locking element 56 protrudes from the top 48 of the segment body 42. The free end of the latching tongue 57 is arranged in particular at a predetermined axial distance to the underlying upper side 48 of the segmented body 42, or its holding part 46 forming the upper region of the segmented body 42.

At the free and axially movable spring-loaded end of the latching tongue 57, a radially outwardly facing edge is formed, which in a horizontal and merges radially outwardly projecting base portion. The edge 58 extends substantially vertically, that is in the axial direction (z). With reaching one in the Fig. 1 and 2 shown final assembly position, the locking element 56 comes with a designed as a through hole 28 counter-latching element 26 of the carrier 12 in operative connection. When inserting the segment body 42 in the receptacle 18, the latching element 56, thus experience its latching tongue 57 downwardly directed elastic deformation. With reaching the in Fig. 2 shown final assembly position, the locking element 56 can dive with its edge 58 from below into the through hole 28 of the counter-latching element 26, wherein the base portion 59 axially on the underside 15 of the carrier 12 comes to rest and limits an upward movement of the locking element 56.

In the in Fig. 2 shown final assembly position reaches the edge 58 radially to the inner wall 30 of the through hole 28 to the plant. In this case, provision is made in particular for the edge 58 to come into abutment with the radially inwardly directed inner wall 30 of the passage opening 28. In this way, the segment body 42 and thus the entire brush segment 40 is secured against a radially outward displacement on the carrier 12.

From the FIGS. 5 and 6 also shows that the segment body 42 of the brush segment 40 is designed in several parts. The segment body 42 has a base part 44, which forms the underside 45 of the segment body 42, from which the bristles 6 protrude and protrude at a predetermined angle. The segment body 42 also has a holding part 46 which, for example, can be positively connected to the base part 44.

The base part 44 has a substantially planar base surface with a plurality of bristle openings 62, through which individual bristles, typically U-shaped bent bristles, can be inserted. Individual legs of U-shaped bent bristles may be inserted through adjacent adjacently arranged bristle openings 62 from above, so that the bristle legs interconnecting U-shaped bent portions of the bristles between the base member 44 and the holding member 46 attached thereto are clamped. That pinching the bent bristle areas at the same time causes a securing of the bristles 6 on the segment body 42 and the brush segment 40th

How out Fig. 6 can be seen, along the outer periphery of the holding part 46 a plurality of downwardly projecting latching members 60 are formed, which is formed with a corresponding thereto counter-latching structure 61 on a side wall or on the side edge 47, 49 of the base member 44. In the present case, the counter-latching structure 61 is designed as a latching strip projecting on the inside of the side edges 47, 49, as shown in FIG Fig. 9 evident. Manufacturing and assembly technology may be provided so far, first provide the base member 44, then the individual bristles 6 or bristle tufts hindurchzustecken from above through the bristle openings 62 and then as the closure cover for the base member 44 acting holding member 46 to connect to the base member 44, thus clipping.

In this case, it is provided in particular that the holding part 46 extends over the entire surface of the base part 44, so that, for example, an outer edge of the holding part 46 comes to bear directly on the corresponding outer edge of the base part 44. In that regard, the directly adjoining reaching edge portions of the base member 44 and holding member 46 can stabilize each other structurally.

It is further provided that on the upper side 48 of the holding part 46, all components of the brush segment 40 which engage in a form-fitting manner with the underside 15 are arranged or formed. On the holding part 46 both segment guides 50, 52 and the latching element 56 are arranged. The latching element 56 is located, with respect to the circumferential direction of the brush segment 40, approximately centrally between the mutually parallel segment guides 50, 52. The holding part 46 is formed together with the segment guides 50, 52 and the latching element 56 designed as a one-piece plastic injection-molded component. Suitable plastics for this purpose are polypropylene, polyamide, polyethylene or mixtures thereof, optionally also fiber-reinforced, in question.

From the representation according to the Fig. 6 and 7 is also apparent that the two segment guides 50, 52 are each designed in several parts. Thus, the in Fig. 7 Segment guide 50 shown on the left has a radially inner or upper guide part 50a and a radially outer or lower guide part 50b. The same applies to the other segment guide 52 with a radially inner guide part 52a and a radially outer guide part 52b.

The provision of two or more radially spaced apart guide parts 50a, 52a and 50b, 52b may prove to be advantageous for a tilt-free insertion or pushing on the continuous and elongated support guides 20, 22 on the underside 15 of the support 12. Slip and / or static friction between the intermeshing segment guides 50, 52 and carrier guides 20, 22 can be reduced in this manner while saving material.

In the illustration according to Fig. 8 the axial position of the locking element 56 to the segment guides 50, 52 can be seen particularly well. In Fig. 9 Finally, it is shown how the two with their free and away from each other, in the circumferential direction outwardly projecting L-shaped legs of the segment guides 50, 52 cooperate with the complementary thereto, inwardly projecting profiles of the support guides 20, 22 form-fitting manner. By means of the complementarily configured and mutually engaging L-shaped profiles 53 of the carrier guide 20, 22 and segment guide 50, 52, the brush segment 40 is axially fixed to the carrier 12.

For an assembly, it is only necessary to align the mutually corresponding profiles of the segment guides 50, 52 corresponding to the carrier guides 20, 22 aligned on the underside 15 of the carrier 12 and to move the brush segment 40 radially inward, corresponding to the longitudinal extent of the carrier guides 20, 22 until the latching element 56 engages with the counter-latching element 26. Characterized in that the counter-latching element 26 is formed as a through hole 28 in the carrier 12, the brush segment 40 can be easily solved by depressing the locking element 56 again from the carrier.

Through the through hole 28 which is latched to the counter-latching element 26 latching element 56 at any time from above particularly simple and accessible through the support plate 14 therethrough. In that regard, not only a tool-free installation, but also a tool-free disassembly of the brush segment 40 from the carrier 12 of the plate recess 10 done.

For the connection to a drive or to a power head of a sweeping or cleaning machine, the carrier 12 may be provided with a hub 70. As in Fig. 3 shown, the hub 70 has a hollow shaft 71 for receiving a drive shaft, which is not shown here. The shaft 71 has, as in Fig. 3 shown, a radial and elongated groove or an internal toothing for forming a torque-transmitting connection with the drive shaft. The shaft 71 is connected to a radially widened flange 73, which can be screwed onto the upper side 16 of the carrier 12, for example. For this purpose, the flange 73 and the support body 12 a plurality of mutually corresponding and mutually aligned in the mounting position mounting holes, through which a fastening means, for example in the form of a bolt can be passed. Instead of being fastened to the upper side 16 of the carrier 12, it is also conceivable to arrange the hub 70 with its flange 73 on the underside 15 of the carrier so that the shaft 71 projects axially through a passage opening 13 of the carrier.

Instead of a multi-part embodiment of carrier 12 and hub 70, the hub 70 and the carrier 12 may also be configured in one piece, or in one piece, for example in the form of a plastic injection-molded component.
