Der Borstenbesatz 14 weist aus häarartigen Borsten 14' bestehende Borstenbüschel auf, die in bekannter Art und Weise in die Vertiefungen gestopft sind. Die Borsten 14' können aus unterschiedlichsten Materialien wie Naturhaar, Kunsthaar, pflanzlichen Fasern, Kunststoffen (wie z. B. Polymex) oder Metall oder aus einer Kombination der genannten Materialien bestehen. Die Borsten 14' des Borstenbesatzes 14 stehen von der Borstenbesatzseite 24 ab, wobei die Borsten in einer Umgebung der Mitte (Mittenborsten) zumindest nahezu rechtwinklig, eine Richtung R definierend, von der Borstenbesatzseite 24 abstehen und die restlichen Borsten (Aussenborsten) je weiter diese von den Mittenborsten entfernt sind von der Richtung R nach aussen abweichen.The bristle stocking 14 comprises bristle-like bristles 14 'consisting of bristle tufts which are stuffed into the recesses in a known manner. The bristles 14 'may consist of a wide variety of materials such as natural hair, synthetic hair, vegetable fibers, plastics (such as Polymex) or metal or a combination of the materials mentioned. The bristles 14 'of the bristle facing 14 protrude from the bristle facing side 24, wherein the bristles project in an environment of the middle (middle bristles) at least approximately at right angles, defining a direction R, from the bristle facing side 24 and the remaining bristles (outer bristles) the further from the center bristles are different from the direction R to the outside.

Die Länge der Borsten 14' wird vorzugsweise zwischen 35 mm und 150 mm und der Durchmesser der Borsten 14' wird vorzugsweise zwischen 0.1 mm und 3.0 mm gewählt. Die Vertiefungen im Borstenträger 12a in welche die Borstenbüschel gestopft sind, weisen vorzugsweise einen Durchmesser von etwa 4mm auf.The length of the bristles 14 'is preferably between 35 mm and 150 mm and the diameter of the bristles 14' is preferably selected between 0.1 mm and 3.0 mm. The recesses in the bristle carrier 12a into which the bristle tufts are stuffed preferably have a diameter of about 4 mm.

Eine Borstenbesatzmantelfläche 26 ist eine den Borstenbesatz 14 umhüllende Fläche, in welcher die äussersten Borsten 14' des Borstenbesatzes 14 liegen. In diesem Ausführungsbeispiel wird die Borstenbesatzmantelfläche 26 nur durch eine äussere Borstenbesatzmantelfläche 26' gebildet. In nachfolgenden Ausführungsbeispielen kommen innere Borstenbesatzmantelflächen 26" hinzu.A bristle embossing surface 26 is a surface surrounding the bristle stock 14 in which the outermost bristles 14 'of the bristle trim 14 lie. In this exemplary embodiment, the bristle-embossing jacket surface 26 is formed only by an outer bristle-embossing jacket surface 26 '. In subsequent exemplary embodiments, inner bristle embossing lateral surfaces 26 "are added.

Die Ausrichtung der Aussenborsten, welche auf der äusseren Borstenbesatzmantelfläche 26' liegen, kann bis zu 45 Grad von der Richtung R abweichen.The orientation of the outer bristles which lie on the outer bristle embossing surface 26 'may deviate up to 45 degrees from the direction R.

Am Borstenträger 12a sind an dessen Endbereichen 16, welche in Längsrichtung L voneinander abgewandt sind, Aussenlamellen 18 angebracht. Jede Gruppe von Aussenlamellen 18 ist über einen U-förmigen Lamellenträger 27 am Borstenträger 12a befestigt. Dafür weist der Borstenträger 12a Nuten 28 und Verankerungslöcher 30 auf. Die Nuten 28 sind an den Endbereichen 16 im Bereich der Seitenflächen 23 in den Borstenträger 12a eingeformt und an jedem Ende der Nuten 28 befindet sich ein Verankerungsloch 30. Die Lamellenträger 27 weisen eine in die Nuten 28 passende Wulst und Haltenasen 32 auf, die formschlüssig in die Nuten 28 und die jeweiligen Verankerungslöcher 30 eingreifen. Die an diese Lamellenträger 27 angeordneten Aussenlamellen 18 sind stabförmig und weisen eine annähernd rechteckige Querschnittsfläche auf, wobei die Grösse und die Form der Querschnittsfläche über die Länge der Aussenlamellen 18 variieren kann. Die bevorzugte Grösse der Querschnittsfläche der stabförmigen Aussenlamellen 18 liegt zwischen 0.25mm2 und 50mm2. In bevorzugter Weise nimmt die Grösse der Querschnittsfläche zum freien Ende der Aussenlamellen 18 hin stetig ab.On the bristle carrier 12 a outer lamellae 18 are attached to the end portions 16 which are remote from each other in the longitudinal direction L. Each group of outer plates 18 is attached via a U-shaped plate carrier 27 on the bristle carrier 12a. For this purpose, the bristle carrier 12a has grooves 28 and anchoring holes 30. The grooves 28 are formed at the end portions 16 in the region of the side surfaces 23 in the bristle carrier 12a and at each end of the grooves 28 is an anchoring hole 30. The plate carrier 27 have a groove 28 in the matching bead and retaining lugs 32, the form-fitting in the grooves 28 and the respective anchoring holes 30 engage. The outer plates 18 arranged on these plate carriers 27 are bar-shaped and have an approximately rectangular cross-sectional area, wherein the size and the shape of the cross-sectional area can vary over the length of the outer plates 18. The preferred size of the cross-sectional area of the rod-shaped outer plates 18 is between 0.25 mm 2 and 50 mm 2 . In a preferred manner, the size of the cross-sectional area decreases continuously towards the free end of the outer disks 18.

Anstelle eines rechteckförmigen Querschnittes können die stabförmigen Aussenlamellen 18 auch andere Formen von Querschnittsflächen aufweisen. Beispielsweise können die stabförmigen Aussenlamellen 18 dreieckige, viereckige, rechteckige, kreisförmige, ellipsenförmige, polygonartige, S-förmige, sternförmige oder 8-förmige Querschnittsflächen aufweisen. Einige dieser Beispiele sind in Figur 12 gezeigt.Instead of a rectangular cross-section, the rod-shaped outer plates 18 may also have other shapes of cross-sectional areas. For example, the rod-shaped outer plates 18 may have triangular, quadrangular, rectangular, circular, elliptical, polygonal, S-shaped, star-shaped or 8-shaped cross-sectional areas. Some of these examples are in FIG. 12 shown.

Die integral mit den Aussenlamellen 18 gespritzten Lamellenträger 27 werden bevorzugt aus einem Kunststoff wie zum Beispiel einem thermoelastischen Elastomer, aus Polyethylen (PE), aus Polypropylen (PP) oder aus einem Gemisch der genannten Materialien gefertigt. Die Aussenlamellen 18 werden zum Beispiel an den Lamellenträger 27 angespritzt oder die Aussenlamellen 18 werden zusammen mit dem Lamellenträger 27 in einem Zwei- oder Mehrkomponentenspritzverfahren hergestellt. Zur Montage werden die Lamellenträger 27 an den Enden aufgespreizt und in Längsrichtung L in die Nuten 28 des mit Borsten 14' besetzten Borstenträger 12a eingefahren bis die Haltenasen 32 in die Verankerungslöcher 30 eingreifen und der Lamellenträger 27 fest vom Borstenträger 12a gehalten ist.The plate carriers 27 injected integrally with the outer plates 18 are preferably made of a plastic such as, for example, a thermoelastic elastomer, polyethylene (PE), polypropylene (PP) or a mixture of the materials mentioned. The outer plates 18 are, for example, molded onto the plate carrier 27 or the outer plates 18 are produced together with the plate carrier 27 in a two-component or multi-component injection molding process. For assembly, the plate carriers 27 are spread open at the ends and retracted in the longitudinal direction L into the grooves 28 of bristle 14 'occupied bristle carrier 12a until the retaining lugs 32 engage in the anchoring holes 30 and the plate carrier 27 is held firmly by the bristle carrier 12a.

Die Ausrichtung der Aussenlamellen 18 ist bei auf den Borstenträger 12a aufgesetztem Lamellenträger 27 so gewählt, dass die Aussenlamellen 18 zumindest nahezu an die äussere Borstenbesatzmantelfläche 26' des Borstenbesatzes 14 anliegen und zumindest nahezu parallel zu benachbarten äussersten Borsten 14' des Borstenbesatzes 14 verlaufen, wobei das freie Ende der Aussenlamellen 18 bevorzugt näher an der Borstenbesatzseite 24 liegt als das freie Ende der Borsten 14' des Borstenbesatzes 14.The orientation of the outer plates 18 is selected so that the outer plates 18 at least almost rest against the outer Borstenbesatzmantelfläche 26 'of the bristle trim 14 and at least almost parallel to adjacent outermost bristles 14' of the bristle facing 14, with the attached to the bristle carrier 12a plate carrier 27, wherein the free end of the outer blade 18 is preferably closer to the bristle facing side 24 than the free end of the bristles 14 'of the bristle trim 14th

In einer anderen Ausführungsform können die zumindest nahezu an die äussere Borstenbesatzmantelfläche 26' anliegenden Aussenlamellen 18 anstatt parallel zu benachbarten äussersten Borsten 14' des Borstenbesatzes 14 mit einem Winkel von bis zu 40 Grad zu benachbarten äussersten Borsten 14' verlaufen. Anstatt nur einreihig können die Aussenlamellen 18 auch zwei- oder mehrreihig angeordnet sein.In another embodiment, the outer plates 18 abutting the outer bristle covering surface 26 'at least almost parallel to adjacent outermost bristles 14' of the bristle lining 14 may extend at an angle of up to 40 degrees to adjacent outermost bristles 14 '. Instead of only single row, the outer plates 18 can also be arranged in two or more rows.

Ausführungsformen bei denen die freien Enden der Aussenlamellen 18 und die freien Enden der Borsten 14' des Borstenbesatzes 14 gleich weit von der Borstenbesatzseite 24 entfernt sind oder bei denen die freien Enden der Aussenlamellen 18 weiter entfernt sind von der Borstenbesatzseite 24 als die freien Enden der Borsten 14' des Borstenbesatzes 14 sind ebenfalls möglich. Vorzugsweise ist der Unterschied der Abstände der freien Enden der Aussenlamellen 18 zur Borstenbesatzseite 24 und der freien Enden der Borsten 14' des Borstenbesatzes 14 zur Borstenbesatzseite 24 kleiner als 10mm.Embodiments in which the free ends of the outer blades 18 and the free ends of the bristles 14 'of the bristle trim 14 are equidistant from the bristle trim side 24 or where the free ends of the outer blades 18 are farther from the bristle trim side 24 than the free ends of the bristles 14 'of the bristle trim 14 are also possible. Preferably, the difference of the distances of the free ends of the outer disk 18 to the bristle facing side 24 and the free ends of the bristles 14 'of the bristle facing 14 to the bristle facing side 24 is less than 10mm.

Ein Kehrgerätekopf 10 für einen Handwischer oder für eine Fegbürste unterscheidet sich vom Kehrgerätekopf 10 für einen Bodenwischer oder für einen Schrubber dadurch, dass auf den Besenstilhalter 20 verzichtet wird, und beim Handwischer wird an den Borstenträger 12a zusätzlich ein Handgriff angeformt. Der Borstenträger 12a für einen Handwischer oder für eine Fegbürste ist vorzugsweise zwischen 5cm und 30cm lang, zwischen 2cm und 10cm breit und zwischen 0.3cm und 5cm hoch.A sweeping head 10 for a hand wiper or for a sweeping brush differs from the sweeping head 10 for a floor wiper or a scrubber in that the brush holder 20 is dispensed with, and in the hand wiper 12a, a handle is additionally formed on the bristle carrier. The bristle carrier 12a for a hand wiper or for a brush is preferably between 5cm and 30cm long, between 2cm and 10cm wide and between 0.3cm and 5cm high.

Für den Kehrgerätekopf 10 für den Handwischer wird der Handgriff in Längsrichtung L an den Borstenträger 12a angeformt.For the sweeping head 10 for the hand wiper handle in the longitudinal direction L is formed on the bristle carrier 12a.

Die Länge der Borsten 14' für den Schrubber wird vorzugsweise zwischen 15mm und 60mm und der Durchmesser der Borsten 14' wird vorzugsweise zwischen 0.1mm und 4.0mm gewählt. Die Länge der Aussenlamellen 18 sind an diese Längen entsprechend anzupassen.The length of the bristles 14 'for the scrubber is preferably between 15mm and 60mm and the diameter of the bristles 14' is preferably chosen between 0.1mm and 4.0mm. The length of the outer plates 18 are adapted to these lengths accordingly.

Für die in den Figuren 3 bis 5 gezeigten Ausführungsformen des Kehrgerätekopfes 10 für einen Bodenwischer oder für einen Schrubber wird ein in Figur 2 gezeigter Borstenträger 12b verwendet. Als Borstenbesatz 14 wird für diesen Borstenträger 12b der in Zusammenhang mit Figur 1 beschriebene Borstenbesatz 14 verwendet. Die Besetzung des Borstenträgers 12b mit Borstenbüscheln erfolgt wie für den Borstenträger 12a in derselben Art und Weise.For those in the FIGS. 3 to 5 shown embodiments of the sweeping head 10 for a floor wiper or a scrubber is a in FIG. 2 shown bristle carrier 12b used. As bristle trim 14 is for this bristle carrier 12 b in connection with FIG. 1 described bristle stock 14 used. The bristle carrier 12b is filled with bristle tufts in the same way as for the bristle carrier 12a.

Der Borstenträger 12b hat weitgehend dieselbe Gestalt und ist aus demselben Material und in derselben Weise gefertigt wie der Borstenträger 12a für einen Bodenwischer oder für einen Schrubber. Der Borstenträger 12b weist auch dieselben Masse auf wie der Borstenträger 12a für einen Bodenwischer oder für einen Schrubber. Der Borstenträger 12b unterscheidet sich vom Borstenträger 12a dadurch, dass er keine Nuten 28 und keine Verankerungslöcher 30 aufweist. Zusätzlich weist der Borstenträger 12b jedoch schlitzartige Durchgänge 34, Aussparungen 36 und Löcher 38 auf.The bristle carrier 12b has substantially the same shape and is made of the same material and in the same manner as the bristle carrier 12a for a floor wiper or for a scrubber. The bristle carrier 12b also has the same mass as the bristle carrier 12a for a floor wiper or for a scrubber. The bristle carrier 12b differs from the bristle carrier 12a in that it has no grooves 28 and no anchoring holes 30. In addition, however, the bristle carrier 12b has slit-like passages 34, recesses 36 and holes 38.

Die schlitzartigen Durchgänge 34 führen dazu, dass Gebiete an der Borstenbesatzseite 24 entstehen, die nicht mit Borsten besetzt sind, wodurch Lücken 35 im Borstenbesatz 14 entstehen. In Analogie zur äusseren Borstenbesatzmantelfläche 26' werden dadurch innere Borstenbesatzmantelflächen 26" gebildet. Jede innere Borstenbesatzmantelfläche 26" umhüllt eine Lücke 35 und die an diese Lücke angrenzenden Borsten 14'. Wie im Zusammenhang mit dem ersten Ausführungsbeispiel erwähnt, wird die Borstenbesatzmantelfläche 26 durch die äussere Borstenbesatzmantelfläche 26' und die inneren Borstenbesatzmantelflächen 26" gebildet.The slot-like passages 34 cause areas on the bristle facing side 24 are formed which are not occupied by bristles, whereby gaps 35 in the bristle trim 14 arise. In correspondence with the outer bristle-embossing jacket surface 26 ', inner bristle-embossing jacket surfaces 26 "are thereby formed. Each inner bristle-embossing jacket surface 26" encloses a gap 35 and the bristles 14 'adjacent to this gap. As mentioned in connection with the first embodiment, the bristle-embossing surface 26 is formed by the outer bristle-embossing surface 26 'and the inner bristle-embossing surface 26 ".

Die in Längsrichtung L länglichen, schlitzartigen Durchgänge 34 sind von der Oberseite 22 zur Borstenbesatzseite 24 verlaufend in den Borstenträger 12b mittig eingeformt. An einem dem Borstenbesatz 14 zugewandten Bereich der Seitenflächen 23 sind mehrere Aussparungen 36 angebracht. Für die Befestigung des Besenstielhalters 20 sind zwei Löcher 38 vorgesehen, wobei der Besenstielhalter 20 zwei Noppen aufweist, die in diese Löcher 38 eingreifen. Fixiert wird der Besenstielhalter 20 mittels einer in den Borstenträger 12b einzudrehenden Schraube 40.The slot-like passages 34 which are elongate in the longitudinal direction L are formed centrally in the bristle carrier 12b from the upper side 22 to the bristle-filling side 24. At a bristle facing 14 facing region of the side surfaces 23 a plurality of recesses 36 are attached. For the attachment of the broomstick holder 20, two holes 38 are provided, wherein the broomstick holder 20 has two nubs, which engage in these holes 38. The broomstick holder 20 is fixed by means of a screw 40 to be screwed into the bristle carrier 12b.

Ein Kehrgerätekopf 10 für einen Handwischer oder für eine Fegbürste unterscheidet sich vom Kehrgerätekopf 10 für einen Bodenwischer oder für einen Schrubber dadurch, dass auf den Besenstilhalter 20 und die Löcher 38 verzichtet wird, und beim Handwischer wird an den Borstenträger 12b zusätzlich ein Handgriff angeformt. Die Masse für den Borstenträger 12b für einen Handwischer oder für eine Fegbürste sind dieselben wie für den Borstenträger 12a für einen Handwischer oder für eine Fegbürste.A sweeping head 10 for a hand wiper or for a sweeping brush differs from the sweeping head 10 for a floor wiper or a scrubber in that the brush holder 20 and the holes 38 is omitted, and the hand wiper 12b, a handle is additionally formed on the bristle carrier. The mass for the bristle carrier 12b for a hand wiper or for a sweeping brush are the same as for the bristle carrier 12a for a hand wiper or for a sweeping brush.

In den Figuren 3 bis 5 sind verschiedene Ausführungsform einer länglichen, eine Längsrichtung L definierenden Lamellenkappe 42 mit Lamellenbesatz 15 gezeigt. Die Lamellenkappe 42 wird von der Oberseite 22 her auf den bereits mit Borsten 14' besetzten Borstenträger 12b aufgesetzt. In den Abbildungen 3 bis 5 ist der Verlauf des Borstenbesatzes 14 für den Fall, dass die Lamellenkappe 42 auf den Borstenträger 12b aufgesetzt ist, punktiert angedeutet.In the FIGS. 3 to 5 different embodiments of an elongated, a longitudinal direction L-defining lamellar cap 42 with lamellar trim 15 are shown. The lamellar cap 42 is placed from the upper side 22 onto the bristle carrier 12b already occupied with bristles 14 '. Figures 3 to 5 show the course of the Bristle trim 14 in the event that the lamellar cap 42 is placed on the bristle carrier 12b, dotted lines indicated.

Die Lamellenkappe 42 ist auf den Borstenträger 12b aus Figur 2 passend geformt. An ihrer Innenseite weist die Lamellenkappe 42 Noppen 46 auf, welche dafür bestimmt sind, in die Aussparungen 36 des Borstenträgers 12b einzugreifen, wodurch die Lamellenkappe 42 mit dem Borstenträger 12b verbunden wird.The lamellar cap 42 is made on the bristle carrier 12b FIG. 2 shaped appropriately. On its inside, the lamellar cap 42 has nubs 46, which are intended to engage in the recesses 36 of the bristle carrier 12b, whereby the lamellar cap 42 is connected to the bristle carrier 12b.

Wie in Figur 3 gezeigt, sind in einer ersten Ausführungsform der Lamellenkappe 42 einen Lamellenbesatz 15 bildende Aussenlamellen 44 von der Lamellenkappe 42 abstehend angeformt. Bei auf den Borstenträger 12b aufgesetzter Lamellenkappe 42 mit den daran angeordneten Aussenlamellen 44, umgeben die Aussenlamellen 44 den Borstenbesatz 14 und liegen zumindest nahezu an die äussere Borstenbesatzmantelfläche 26' an. Die Aussenlamellen 44 haben annähernd die Form eines schlanken, gleichschenkligen Trapezes mit einer längeren und einer kürzeren Parallelseite, wobei die längere Parallelseite bei der Lamellenkappe 42 liegt. In ihrer Längsrichtung sind die Aussenlamellen 44 jeweils symmetrisch entlang einer Lamellenachse 47 (nur bei einer Aussenlamelle 44 eingezeichnet) geformt und die Lamellenachse 47 verläuft zumindest annähern parallel zu benachbarten äussersten Borsten 14'. Eine Querschnittsfläche durch eine Aussenlamelle 44 weist vorzugsweise eine Grösse zuwischen 0.25mm2 und 50mm2 auf.As in FIG. 3 Shown in a first embodiment of the lamellar cap 42 a lamellae 15 forming outer fins 44 of the lamellar cap 42 are formed projecting. When mounted on the bristle carrier 12b lamellar cap 42 with the outer plates arranged thereon 44, the outer plates 44 surround the bristle stocking 14 and are at least almost to the outer bristle coating surface 26 'at. The outer plates 44 have approximately the shape of a slender, isosceles trapezium with a longer and a shorter parallel side, the longer parallel side is at the lamella 42. In their longitudinal direction, the outer plates 44 are each symmetrically along a blade axis 47 (shown only with an outer plate 44) formed and the blade axis 47 extends at least approximately parallel to adjacent outermost bristles 14 '. A cross-sectional area by an outer plate 44 preferably has a size zuwischen 0.25mm 2 and 50mm. 2

Der an die kürzere Parallelseite angrenzende Endbereich der Aussenlamellen 44 ist mehrfach, vom freien Ende her geschlitzt und bildet feine Lamellen-Stäbchen 48. Die Ausrichtung der feinen Stäbchen 48 der Aussenlamellen 44 ist so gewählt, dass diese, bei auf den Borstenträger 12b aufgesetzter Lamellenkappe 42 zumindest nahezu parallel zu benachbarten äussersten Borsten 14' des Borstenbesatzes 14 verlaufen. Wiederum bei aufgesetzter Lamellenkappe 42 auf den Borstenträger 12b, kann die Länge der Aussenlamellen 44 kürzer, gleichlang oder länger als die Länge der benachbarten Borsten 14' des Borstenbesatzes 14 gewählt werden, wobei wie in Fig. 3 gezeigt die gleichlange Ausführung bevorzugt ist.The adjacent to the shorter parallel side end portion of the outer plate 44 is repeatedly, slotted from the free end and forms fine lamellar rods 48th Die Alignment of the fine rods 48 of the outer disk 44 is selected so that they extend at least almost parallel to adjacent outermost bristles 14 'of the bristle lining 14, when attached to the bristle carrier 12b lamella 42. Again, with the lamella cap 42 mounted on the bristle carrier 12b, the length of the outer lamellae 44 may be shorter, equal to, or longer than the length of the adjacent bristles 14 'of the bristle lining 14, as in FIG Fig. 3 shown the same length execution is preferred.

In einer anderen Ausführungsform können die zumindest nahezu an die äussere Borstenbesatzmantelfläche 26'' anliegenden Aussenlamellen 44 anstatt mit ihrer Lamellenachse 47 zumindest nahezu parallel zu benachbarten äussersten Borsten 14' des Borstenbesatzes 14 mit einem Winkel von bis zu 40 Grad zu benachbarten äussersten Borsten 14' des Borstenbesatzes 14 verlaufen.In another embodiment, the outer lamellae 44, which abut at least almost on the outer bristle embossing lateral surface 26 ", can be at least almost parallel to adjacent outermost bristles 14 'of the bristle trimming 14 at an angle of up to 40 degrees to adjacent outermost bristles 14' of the bristle trimming 14 Bristle trim 14 run.

Es ist noch zu bemerken, dass, falls die Lamellenkappe 42 nur Aussenlamellen 44 aufweist, die Durchgänge 34 des Borstenträgers 12b nicht benötigt werden und somit auf diese Durchgänge 34 verzichtet werden könnte.It should also be noted that if the lamellar cap 42 only has outer lamellae 44, the passages 34 of the bristle carrier 12b are not required and thus these passages 34 could be dispensed with.

In einer weiteren Ausführungsform, welche in Figur 4 gezeigt ist, sind an der Lamellenkappe 42, anstelle der Aussenlamellen 44 der in Figur 3 gezeigten Ausführungsform, Innenlamellen 50 angeordnet, welche mittig in Längsrichtung L verlaufen und den Lamellenbesatz 15 bilden. Weiter sind die Innenlamellen 50 so angeordnet, dass diese, bei auf den Borstenträger 12b aufgesetzter Lamellenkappe 42, die Aussparungen 36 des Borstenträgers 12b - Fig. 2 - durchgreifen, und die Ausrichtung der Innenlamellen 50 ist so gewählt, dass die Innenlamellen 50 zumindest nahezu an die innere Borstenbesatzmantelflächen 26" des Borstenbesatzes 14 anliegend und zumindest nahezu rechtwinklig zur Borstenbesatzseite 24 verlaufen. Die Innenlamellen 50 weisen eine zungen- oder plattenartige Rechtecksform auf, wobei die Dicke der Innenlamellen 50 vorzugsweise mit zunehmendem Abstand von der Lamellenkappe 42 abnimmt und vorzugsweise zwischen 1mm und 10mm dick ist. Die Innenlamellen 50 sind, in dem von der Lamellenkappe 42 abgewandten freien Endbereich, in in der Richtung R verlaufende, runde Lamellen-Stäbchen 52 unterteilt. Im aufgesetzten Zustand der Lamellenkappe 42 auf den Borstenträger 12b, können die freien Enden der Innenlamellen 50 und die freien Enden der Borsten 14' des Borstenbesatzes 14 näher, gleichweit oder weiter von der Borstenbesatzseite 24 entfernt sein, wobei eine Ausbildungsform mit etwas näher zur Borstenbesatzseite 24 gelegenen freien Enden der Innenlamellen 50 als die freien Enden der Borsten 14' des Borstenbesatzes 14 liegen, bevorzugt ist.In a further embodiment, which in FIG. 4 are shown are on the lamellar cap 42, instead of the outer blade 44 of in FIG. 3 shown embodiment, inner plates 50 are arranged, which run centrally in the longitudinal direction L and form the lamellar trim 15. Furthermore, the inner disks 50 are arranged such that, when the disk cap 42 is attached to the bristle carrier 12b, they engage the cutouts 36 of the bristle carrier 12b. Fig. 2 - pass through, and the orientation of the inner disk 50 is selected so that the inner disk 50th extend at least almost to the inner bristle embossing lateral surfaces 26 "of the bristle trim 14 and at least approximately perpendicular to the bristle facing side 24. The inner plates 50 have a tongue-like or plate-like rectangular shape, the thickness of the inner plates 50 preferably decreases with increasing distance from the lamellar cap 42 and preferably The inner lamellae 50 are, in the free end region facing away from the lamellae cap 42, divided into round lamellae rods 52 extending in the direction R. In the fitted state of the laminae cap 42 on the bristle carrier 12b, the free ones can Ends of the inner fins 50 and the free ends of the bristles 14 'of the bristle trim 14 closer, equidistant or farther away from the bristle trim side 24, wherein an embodiment with slightly closer to the bristle facing side 24 free ends of the inner fins 50 as the free ends of the bristles 14' of bristle trim 14 lie n, is preferred.

Die Differenz der Abstände der freien Enden der Innenlamellen 50 zur Borstenbesatzseite 24 zu den freien Enden der Borsten 14' sollte 10mm nicht übersteigen. Die Länge der Lamellen-Stäbchen 52 liegt vorzugsweise zwischen 3mm und 20mm. Der Durchmesser der Lamellen-Stäbchen 52 liegt vorzugsweise zwischen 0.1mm und 3.0mm.The difference in the distances of the free ends of the inner plates 50 to the bristle side 24 to the free ends of the bristles 14 'should not exceed 10mm. The length of the lamellar rods 52 is preferably between 3mm and 20mm. The diameter of the lamellar rods 52 is preferably between 0.1 mm and 3.0 mm.

Anstelle der in Längsrichtung L mittig angeordneten, länglichen, geraden Durchgänge 34 können die Durchgänge andere Formen aufweisen, wie z. B. längliche, zickzackförmige oder längliche, wellenlinienförmige (sinusförmige) Formen. Anstatt die Durchgänge 34 in Längsrichtung L mittig anzuordnen, können die Durchgänge 34 auch abweichend von dieser in Längsrichtung L mittigen Anordnung angeordnet sein. Weitere Formen für die Durchgänge 34 wie Kreise, Ellipsen und Rechtecke sind ebenfalls möglich. Die Anordnung der Innenlamellen 50 an der Lamellenkappe 42 ist an die Anordnung der Durchgänge 34 anzupassen. Es können anstelle der einreihigen Ausbildungsform auch zwei- oder mehrreihige Ausbildungsformen der Innenlamellen zur Anwendung kommen.Instead of in the longitudinal direction L arranged centrally, elongated, straight passages 34, the passages may have other shapes, such as. As elongated, zigzag or elongated, wavy (sinusoidal) shapes. Instead of centering the passages 34 in the longitudinal direction L, the passages 34 may also be centered in the longitudinal direction L, notwithstanding this Arrangement can be arranged. Other shapes for the passages 34 such as circles, ellipses and rectangles are also possible. The arrangement of the inner plates 50 on the lamella cap 42 is adapted to the arrangement of the passages 34. Instead of the single-row embodiment, it is also possible to use two or more rows of embodiments of the inner disks.

Anstelle der zungen- oder plattenartigen Innenlamellen 50 sind auch stabförmige Innenlamellen denkbar, analog zu den verschiedenen Ausführungen der Aussenlamellen 18, 44.Instead of the tongue or plate-like inner fins 50, rod-shaped inner fins are also conceivable, analogous to the different embodiments of the outer fins 18, 44.

In Figur 5 ist eine Kombination der beiden in den Figuren 3 und 4 gezeigten Ausführungsformen gezeigt, in welcher sowohl die Aussenlamellen 44 wie auch die Innenlamellen 50 an der Lamellenkappe 42 in oben beschriebener Art und Weise zusammen angeformt sind. Sämtliche im Zusammenhang mit den in den Figuren 3 und 4 aufgezeigten weitern Ausführungsformen der Borstenträgers 12b der Aussenlamellen 44, der Innenlamellen 50 und der Lamellenkappe 42 können auch bei einer kombinierten Ausführungsform zur Anwendung kommen.In FIG. 5 is a combination of the two in the FIGS. 3 and 4 shown embodiments, in which both the outer disk 44 and the inner disk 50 are integrally formed on the disk cap 42 in the manner described above. All in connection with those in the FIGS. 3 and 4 Further embodiments of the bristle carrier 12b of the outer disks 44, the inner disks 50 and the disk cap 42 can also be used in a combined embodiment.

Als Material für den Lamellenbesatz 15, bestehend aus Aussenlamellen 44 und/oder Innenlamellen 50, wie auch für die Lamellenkappe 42 wird von Vorteil ein thermoplastisches Elastomer, Polypropylen (PP), Polyethylen (PE) oder ein Gemisch der genannten Materialen verwendet.As a material for the lamellae 15, consisting of outer plates 44 and / or inner plates 50, as well as for the lamellar cap 42 is advantageously a thermoplastic elastomer, polypropylene (PP), polyethylene (PE) or a mixture of said materials used.

Die dem Lamellenträger 27 beziehungsweise der Lamellenkappe 42 gegenüberliegenden, freien Endbereiche des Lamellenbesatzes 15 können auch anders als oben beschrieben geformt werden. Die nachfolgend beschriebenen Ausführungsformen für die freien Endbereiche der Innenlamellen 50 können sinngemäss auf die Endbereiche der Aussenlammellen 18, 44 oder der stabförmigen Innenlamellen übertragen werden.The lamella carrier 27 or the lamellar cap 42 opposite, free end portions of the lamellae 15 can also be shaped differently than described above. The embodiments described below for the free end regions of Inner fins 50 can be transferred analogously to the end regions of the outer plates 18, 44 or the rod-shaped inner plates.

In den Figuren 6 und 7 ist die Ausführungsform der Innenlamelle 50 mit Stäbchen 52 detaillierter gezeigt. Am freien Endbereich der Innenlamellen 50 sind zwei, in Längsrichtung L verlaufende Reihen von Stäbchen 52 angeordnet, wobei die Stäbchen 52 parallel und in Richtung R verlaufend ausgerichtet sind. Eine einreihige Ausführungsform oder eine mehr als zweireihige Ausführungsform ist selbstverständlich ebenfalls möglich.In the FIGS. 6 and 7 For example, the embodiment of the inner fin 50 with rods 52 is shown in more detail. At the free end region of the inner disk 50, two, extending in the longitudinal direction L rows of rods 52 are arranged, wherein the rods 52 are aligned parallel and in the direction R extending. A single-row embodiment or a more than two-row embodiment is of course also possible.

Anstelle der Rechtecksform der Innenlamellen 50 sind auch andere Formen denkbar, insbesondere solche, die bei auf den Borstenträger 12b aufgesetzter Lamellenkappe 42 der Ausrichtung der den Kanten dieser Formen benachbarten Borsten des Borstenbesatzes 14 Rechnung tragen, wie zum Beispiel eine Trapezform.Instead of the rectangular shape of the inner lamellae 50, other shapes are also conceivable, in particular those which, when the lamellar cap 42 is placed on the bristle carrier 12b, take into account the alignment of the bristles of the bristle facing 14 adjacent to the edges of these shapes, for example a trapezoidal shape.

Zwei weitere Ausführungsformen für Innenlamellen 50 mit bezüglich der Richtung R schräg gestellten Stäbchen sind in den Figuren 8 bis 11 gezeigt. Die Ausführungsform gemäss den Figuren 8 und 9 unterscheidet sich von der bereits erwähnten Ausführungsform der Innenlamellen 50 mit zweireihig angeordneten, in Richtung R ausgerichteten Stäbchen 52 - Fig. 6 und 7 - dadurch, dass die Stäbchen 52 der einen Reihe und jener der anderen Reihe, bezüglich der Richtung R in Längsrichtung L gegenseitig schräg verlaufen. Die Ausführungsform gemäss den Figuren 10 und 11 unterscheidet sich von der Ausführungsform der Innenlamellen 50 mit zweireihig angeordneten, in Richtung R ausgerichteten Stäbchen 52 - Fig. 6 und 7 - dadurch, dass die Stäbchen 52 der einen Reihe jene der anderen Reihe kämmend kreuzen. Die Stäbchen 52 weichen in beiden Ausführungsformen vorzugsweise nicht mehr als 45 Grad von der Richtung R ab.Two further embodiments for inner plates 50 with respect to the direction R inclined rods are in the FIGS. 8 to 11 shown. The embodiment according to the FIGS. 8 and 9 differs from the already mentioned embodiment of the inner disk 50 with two rows arranged, aligned in the direction of R rods 52 - 6 and 7 - In that the rods 52 of one row and those of the other row, with respect to the direction R in the longitudinal direction L are mutually inclined. The embodiment according to the FIGS. 10 and 11 differs from the embodiment of the inner fins 50 with two rows arranged, aligned in the direction R rods 52 - 6 and 7 - in that the rods 52 of one row are those of the other Intersecting row combing. The rods 52 preferably do not deviate more than 45 degrees from the direction R in both embodiments.

Entsprechend den verschiedenen Ausführungsformen für die stabförmigen Aussenlamellen 18 können auch die Stäbchen 52 in verschiedenen Ausführungsformen zur Anwendung kommen. Beispielsweise können die Stäbchen 52 dreieckige, viereckige, rechteckige, kreisförmige, ellipsenförmige, polygonartige, S-förmige, sternförmige oder 8-förmige Querschnittsflächen aufweisen. Einige dieser Beispiele sind in Figur 12 gezeigt.According to the various embodiments for the rod-shaped outer lamellae 18, the rods 52 can also be used in various embodiments. For example, the rods 52 may have triangular, quadrangular, rectangular, circular, elliptical, polygonal, S-shaped, star-shaped or 8-shaped cross-sectional areas. Some of these examples are in FIG. 12 shown.

Die zungen- oder plattenförmigen Innenlamellen 50 können auch - ohne Stäbchen 52 - mit einem lappenartigen Endbereich ausgestattet sein. Bei solchen Innenlamellen 50 erweisen sich wenige, in Längsrichtung L möglichst zusammenhängende Innenlamellen 50 als besonders geeignet, insbesondere zum Wasserschieben.The tongue-shaped or plate-shaped inner plates 50 can also be equipped with a flap-like end region-without rods 52. In such inner lamellae 50, a few inner lamellae 50 which are as coherent as possible in the longitudinal direction L prove to be particularly suitable, in particular for pushing water.

Für die Reinigung von mit Haaren und/oder Staub bedeckten Böden ist die Kombination eines Borstenträgers 12a, 12b aus Polypropylen (PP) mit einem Lamellenbesatz 15 aus Polyethylen (PE) wegen der statischen Ladung des Lamellenbesatzes 15 besonders geeignet. Durch die statische Ladung des Lamellenbesatzes 15 werden die Haare und/oder der Staub vom Lamellenbesatz 15 angezogen. Die statische Ladung kann mittels eines Additivs wie z. B. Kohlenstoff verstärkt werden.For the cleaning of soils covered with hair and / or dust, the combination of a bristle carrier 12a, 12b made of polypropylene (PP) with a lamellae 15 made of polyethylene (PE) is particularly suitable because of the static charge of the lamellae 15. Due to the static charge of the lamellar trim 15, the hair and / or the dust from the lamellar trim 15 are tightened. The static charge can by means of an additive such. B. carbon are amplified.

Bei den in den Fig. 3 und 5 gezeigten Ausbildungsformen verlaufen die Aussenlamellen 44 in einer ununterbrochenen Reihe um den Borstenträger 12b bzw. den Borstenbesatz 14 herum. Es ist auch denkbar, die Reihe der Aussenlamellen 44 unterbrochen auszubilden, beispielsweise so dass nur in den Endbereichen 16 des Borstenträgers 12b Aussenlamellen vorhanden sind.In the in the FIGS. 3 and 5 the outer lamellae 44 run around the bristle carrier 12b and the bristle lining 14 in an uninterrupted row. It is also conceivable to form the row of outer disks 44 interrupted, for example so that only in the end portions 16 of the bristle carrier 12b outer plates are present.

Es soll noch darauf hingewiesen werden, dass es auch möglich ist, den Borstenträger 12a, 12b und den Lamellenbesatz 15 einteilig zu fertigen, wobei dann auf den Lamellenträger 27 beziehungsweise auf die Lamellenkappe 42 verzichtet werden kann. An den in einem ersten Arbeitsschritt gespritzten Borstenträger 12a, 12b wird hierzu der Lamellenbesatz 15 angespritzt. Alternativ kann der Borstenträger 12a, 12b zusammen mit dem Lamellenbesatz 15 in einem Arbeitsschritt gefertigt werden. Dazu wird ein Zwei- oder Mehrkomponentenspritzverfahren verwendet. Die Form des Borstenträgers 12a, 12b ist an diese Herstellungsverfahren leicht anzupassen. In einem weiteren Arbeitsschritt wird der Borstenträger 12a, 12b mit den, den Borstenbesatz 14 bildenden Borsten gestopft, wozu eventuell der Lamellenbesatz 15 auf die Seite gedrückt werden muss. In einem darauffolgenden Arbeitsschritt werden die Borsten des Borstenbesatzes 14 auf die gewünschte Länge geschnitten.It should also be pointed out that it is also possible to manufacture the bristle carrier 12a, 12b and the lamella trim 15 in one piece, in which case the plate carrier 27 or the lamella cap 42 can be dispensed with. For this purpose, the lamellar stock 15 is injection-molded onto the bristle carrier 12a, 12b sprayed in a first working step. Alternatively, the bristle carrier 12a, 12b can be manufactured together with the lamellae trim 15 in one work step. For this purpose, a two-component or multi-component injection method is used. The shape of the bristle carrier 12a, 12b is easily adapted to these manufacturing processes. In a further step, the bristle carrier 12a, 12b is stuffed with the bristles forming the bristle stock 14, for which purpose the fin stock 15 may have to be pressed onto the side. In a subsequent step, the bristles of the bristle trim 14 are cut to the desired length.

Für einen Bodenwischer und einen Schrubber wird an einem der oben beschriebenen Kehrgeräteköpfe 10 ein Besenstiel mit Hilfe des Besenstielhalters 20 an den Kehrgerätekopf 10 angebracht.For a floor wiper and a scrubber, a broomstick is attached to the sweeping head 10 by means of the broomstick holder 20 on one of the sweeping device heads 10 described above.

Neben den verbesserten Kehreigenschaften bietet der erfindungsgemässe Kehrgerätekopf 10 Stütz- und Schutzfunktionen. Aussenlamellen 18, 44 schützen Möbel und Wände vor Schlägen. Der Lamellenbesatz 15, insbesondere mit Aussenlamellen 18, 44, bietet für den Borstenbesatz 14 eine Stützfunktion und somit auch eine Schutzfunktion, da der Borstenbesatz 14 bei der auf dem Kehrgerätekopf 10 stehender Lagerung eines Handbesens oder eines Handfegers durch den im Vergleich mit dem Borstenbesatz 14 steifen Lamellenbesatz 15 gestützt wird, wodurch der Borstenbesatz 14 länger in Form bleibt und die Lebensdauer des Kehrgerätekopfes 10 verlängert wird.In addition to the improved Kehreigenschaften the inventive sweeping head 10 provides support and protection functions. Outer plates 18, 44 protect furniture and walls from being hit. The lamellar stocking 15, in particular with outer lamellae 18, 44, provides for the bristle stocking 14 a support function and thus also a protective function, since the bristle trim 14 is supported on the sweeping head 10 standing storage of a hand broom or a Handfegers by the stiff compared with the bristle trim 14 lamellae 15, whereby the bristle trim 14 stays in shape longer and the life of the sweeping head 10 is extended.

Ein weiterer Vorteil des Lamellenbesatzes 15 mit Aussenlamellen 18, 44 zeigt sich beim Kehren von Fugen, Ritzen, Kanten und Ecken da dank den Aussenlamellen 18, 44 diese gut gereinigt werden.Another advantage of Lamellenbesatzes 15 with outer plates 18, 44 shows when sweeping joints, cracks, edges and corners because thanks to the outer plates 18, 44 they are cleaned well.

Der erfindungsgemässe Kehrgerätekopf 10 kann auch für andere Haushaltsbürsten und Haushaltsbesen, wie zum Beispiel eine Schmutzbürste verwendet werden.The inventive sweeper head 10 can also be used for other household brushes and household brooms, such as a dirt brush.
