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
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
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
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
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
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
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

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
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-
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-

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
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
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

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
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,
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

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
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
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

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
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
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
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
Der erfindungsgemässe Kehrgerätekopf 10 kann auch für andere Haushaltsbürsten und Haushaltsbesen, wie zum Beispiel eine Schmutzbürste verwendet werden.The
