Description

Technisches GebietTechnical field

Die Erfindung betrifft einen Gummibesen, umfassen einen Besenkörper mit einer an dessen Unterseite angeordneten, einstückig ineinander übergehend ausgebildeten Borstenbestückung aus einem elastischen, polymeren Werkstoff.The invention relates to a rubber broom, comprising a broom body one arranged on its underside, integrally merging trained bristle assembly from an elastic, polymeric Material.

Stand der TechnikState of the art

Ein solcher Gummibesen ist aus der EP-B 0 405 819 bekannt. Der Besenkörper und die Borstenbestuckung bilden dabei ein einziges Formteil, daß im Spritzgießverfahren erzeugt ist. Das zur Herstellung verwendete Formwerkzeug ist so gestaltet, daß der Rand des Besenkörpers von in seitlicher Richtung vorstehenden Borsten übergriffen ist. Hierdurch ist es möglich, unter Verwendung eines solchen Gummibesens Staub und Schmutz auch aus dem Bereich von Ecken zwischen einer Bodenfläche und einer die Bodenfläche begrenzenden Wand zu entfernen. Die Herstellung des benötigten Formwerkzeugs ist indessen äußerst schwierig und die Ausformung der erzeugten Spritzgießteile problematisch. Häufig reißen hierbei Borsten ab, was einen Gummibesen unverkäuflich macht.Such a rubber broom is known from EP-B 0 405 819. Of the The broom body and the bristle assembly form a single molded part, that is produced in the injection molding process. The one used to manufacture Mold is designed so that the edge of the broom body from in bristles protruding laterally. This is it possible, using such a rubber broom dust and dirt also from the area of corners between a floor surface and a die Remove the wall that delimits the floor area. The production of the required mold is extremely difficult and the molding the injection molded parts produced problematic. Often bristles break off, which makes a rubber broom unsaleable.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt die Aufgabe zugrunde, einen solchen Gummibesen derart weiterzuentwickeln, daß sich bei einfacherer und sicherer Herstellbarkeit Ecken von Räumen ähnlich einfach reinigen lassen wie mit der bekannten Ausführung.The invention has for its object such a rubber broom further develop that with easier and safer manufacturability Have corners of rooms cleaned just as easily as with the known one Execution.

Diese Aufgabe wird erfindungsgemäß bei einem Gummibesen der eingangs genannten Art mit den kennzeichnenden Merkmalen von Anspruch 1 gelöst. Auf vorteilhafte Ausgestaltungen nehmen die Unteransprüche Bezug.This object is achieved with a rubber broom at the beginning said type solved with the characterizing features of claim 1. The subclaims refer to advantageous refinements.

Bei dem erfindungsgemäßen Gummibesen ist es vorgesehen, daß der Besenkörper ein von der Borstenbestückung unabhängig erzeugtes Formteil ist und eine Unterseite aufweist, die in Richtung des Randes an zumindest einer Stelle hochgezogen ist, wobei die Borstenbestückung einen Bestandteil einer verformbaren Tragschicht bildet und wobei die Tragschicht die Unterseite zumindest entlang des umlaufenden Randes anliegend berührt. Die Erfindung macht sich hierbei die Erkenntnis zu Nutze, daß die einen Bestandteil der Borstenbestückung bildende Tragschicht nach ihrer Formgebung und Verfestigung weiterhin verformbar ist, was es erlaubt, der Tragschicht herstellungsbedingt eine im wesentlichen ebene Gestalt zu geben mit im wesentlichen senkrecht darauf angeordneten Borsten und die Tragschicht im Anschluß an ihrer Formgebung und Verfestigung auf einen unabhängig davon hergestellten Besenkörper aufzuspannen, dessen Unterseite in Richtung des Randes zumindest an einer Stelle hochgezogen ist. Die im wesentlichen senkrecht aus der Tragschicht hervorstehenden Borsten werden dabei in dem hochgezogenen Bereich in seitlicher Richtung nach außen verlagert, was es erlaubt, unter Verwendung des erfindungsgemäßen Gummibesens Eckbereiche zwischen dem Fußboden und einer senkrecht darauf stehenden Wand einwandfrei zu reinigen, ohne daß sich eine Anschlagberührung des Besenkörpers an der Wand ergibt.In the rubber broom according to the invention it is provided that the Broom body is a molded part produced independently of the bristle configuration and has an underside which in the direction of the edge on at least one Point is pulled up, the bristle assembly is part of a deformable base layer and wherein the base layer is the underside touched at least along the circumferential edge. The invention makes use of the knowledge that part of the Base layer forming bristle assembly according to their shape and Solidification is still deformable, which allows the base course to give an essentially flat shape with im bristles arranged substantially perpendicular to it and the base layer in the Connection to their shape and solidification on one independently produced broom body, the underside towards the Edge is pulled up at least in one place. The essentially Bristles protruding perpendicularly from the base layer are in the hoisted area shifted sideways outwards what it allowed, using the rubber broom according to the invention Corner areas between the floor and one perpendicular to it Clean the wall perfectly without touching the Broom body on the wall.

Die Borsten können säulenförmig ausgebildet, jedoch bedarfsweise auch im vorspringenden Bereich von verjüngtem Querschnitt sein. Neben kreisförmigen Profilen gelangen bevorzugt rechteckige Profile zur Anwendung, die sich quer zur Reinigungsrichtung erstrecken. Eine überlappende, gegenseitige Zuordnung der Borsten hat sich als vorteilhaft bewährt. Sofern zylindrische Ausbildungen zur Anwendung gelangen, besteht die zusätzliche Möglichkeit, den Borsten zumindest im vorstehenden Bereich ein polygonförmiges, X- oder Y-förmiges Profil zu geben. Hierdurch wird eine wesentlich verbesserte Reinigungswirkung erzielt. Der rückwärtige Bereich kann ein rundes Profil haben, um eine gute Elastizität in allen Richtungen zur Verfügung zu haben.. Die während der bestimmungsgemäßen Verwendung erzielte Reinigungswirkung läßt sich dadurch wesentlich verbessern. Eine Integration von Abstreiflippen in die Borstenbestückung ist ebenfalls möglich, bevorzugt in einer Anordnung, bei der jede zweite Zeile innerhalb der Borstenbestückung durch zumindest einer Abstreiflippe gebildet ist. Eine Abstreiflippe kann dabei auch mehrere in Bewegungsrichtung aufeinander folgende oder seitlich beabstandete Teillippen umfassen, die von begrenzter Länge und einander auf Lücke zugeordnet sind. Die Flexibilität der Abstreiflippe wird hierdurch insgesamt verbessert. In bezug auf das Abstreifen von Schmutz und/oder Wasser von unebenen Oberflächen und insbesondere aus Eintiefungen läßt sich so eine verbesserte Rakelwirkung erzielen.The bristles can be columnar, but if necessary also in protruding area of tapered cross-section. In addition to circular Profiles are preferably rectangular profiles that are used transversely extend to the cleaning direction. An overlapping, mutual assignment the bristle has proven to be advantageous. Provided cylindrical training apply, there is the additional possibility that Bristles are polygonal, X- or Y-shaped, at least in the above area To give profile. This significantly improves Cleaning effect achieved. The rear area can have a round profile to have good elasticity in all directions. The cleaning effect achieved during the intended use can be significantly improved. An integration of wiper lips in the bristle assembly is also possible, preferably in one Arrangement in which every other line within the bristle assembly at least one wiper lip is formed. A wiper lip can also be used several successive or laterally spaced in the direction of movement Partial lips include those of limited length and each other to gap assigned. The flexibility of the wiper lip is hereby overall improved. With regard to wiping off dirt and / or water from uneven surfaces and especially from recesses can be one achieve improved squeegee effect.

Als zweckmäßig hat es sich erwiesen, wenn der Gummibesen symmetrisch gestaltet ist, derart, daß die Unterseite an beiden Enden in Richtung des Randes hochgezogen ist. Ein solcher Gummibesen läßt sich gleich gut in bezug auf die Reinigung rechter wie linker Ecken verwenden, ohne daß es des Umdrehens des Besenkörpers bedarf.It has proven to be useful if the rubber broom is symmetrical is designed such that the bottom at both ends in the direction of Edge is pulled up. Such a rubber broom can be used equally well in with regard to the cleaning of right and left corners, without this Turning the broom body required.

Die Unterseite kann auch auf dem ganzen Umfang in Richtung des Randes hochgezogen sein, um in sämtlichen Richtungen über den Randbereich vorstehende Borsten zur Verfügung zu haben.The bottom can also go all the way towards the edge be pulled up in all directions over the edge area to have the above bristles available.

Im Hinblick auf die einem Kreisbogen angenäherte Schwenkbewegung, die sich während der bestimmungsgemäßen Verwendung eines Besen ergibt, hat es sich als vorteilhaft bewährt, wenn die Unterseite abgerundet in den hochgezogenen Bereich übergeht. Eine Überlastung der an der Übergangsstelle vorhandenen Borsten läßt sich hierdurch vermeiden.With regard to the swiveling movement approximating an arc, the has resulted during the intended use of a broom it has proven to be advantageous if the underside is rounded off in the raised area merges. An overload of at the This makes it possible to avoid existing bristles at the transition point.

Die Unterseite des Besenkörpers kann im zentralen Bereich durch eine unabhängig erzeugte Zwischenplatte gebildet sein, die in eine Öffnung des Besenkörpers einfügbar ist und die den Besenkörper und die Tragschicht miteinander verbindet. Die zusätzliche Herstellung der Zwischenplatte ist zwar mit besonderem Aufwand verbunden, der Aufwand wird jedoch bei weitem wett gemacht durch die sich ergebende Werkstoff- und Gewichtsersparnis. Außerdem eröffnet die Zwischenplatte die Möglichkeit, die Tragschicht nahezu in eine beliebige, konvex nach unten vorstehende Form zu bringen und unverrückbar an dem Besenkörper festzulegen, ohne daß es des Einsatzes eines sekundären Klebstoffes bedarf. Hierzu kann die Tragschicht oberseitig mit sich parallel zu ihrer Längsrichtung erstreckenden Vorsprünge von T-förmigem Profil versehen sein, wobei die Vorsprünge in ihrem Querschnitt entsprechende, nach unten offene Aufnahmen der Zwischenplatte eingefügt sind. Eine derartige Halterung der Tragschicht hat außerdem in gewisser Hinsicht elastisch nachgiebige Eigenschaften, was es weitestgehend ausschließt, daß sich während der bestimmungsgemäßen Verwendung eine unbeabsichtigte Loslösung der Tragschicht von dem Besenkörper ergibt. Auch ist es bei einer solchen Ausbildung nicht erforderlich, für die Herstellung des Besenkörpers und der Tragschicht bzw. der Borsten artverwandte Werkstoffe zu verwenden, um eine hinreichend stabile Festlegung aneinander zu ermöglichen. Sowohl für die Herstellung des Besenkörpers, als auch für der Zwischenplatte und der Tragschicht können daher Werkstoffe verwendet werden, die in spezifischer Weise an die besonderen Erfordernisse des betreffenden Einzelteils angepaßt sind. Als vorteilhaft hat es sich bewährt, für die Herstellung des Besenkörpers Polypropylen zu verwenden, für die Herstellung der Zwischenplatte Polyamid und für die Herstellung der Tragschicht einschließlich der Borsten eine thermoplastisch verarbeitbare Gummisorte (TPE).The underside of the broom body can be opened in the central area independently generated intermediate plate formed in an opening of the Broom body is insertable and the broom body and the base layer connects with each other. The additional manufacture of the intermediate plate is true involves a lot of effort, but the effort is far outweighed made by the resulting material and weight savings. In addition, the intermediate plate opens up the possibility of the base layer almost to bring it into any shape convexly projecting downwards and fix immovably on the broom body without it being insert needs a secondary adhesive. For this purpose, the base layer can be on the top with projections of T-shaped extending parallel to their longitudinal direction Profile be provided, the projections in their cross section Appropriate, open downward recordings of the intermediate plate inserted are. Such a support of the base layer also has a certain degree In terms of resilient properties, it is largely excludes that during the intended use unintentional detachment of the base layer from the broom body results. Also with such training it is not necessary for the production of the Brush body and the base layer or the bristles related materials to use to make a sufficiently stable fixation to each other enable. Both for the manufacture of the broom body, as well as for the The intermediate plate and the base layer can therefore use materials be, which in a specific way to the special requirements of the relevant item are adjusted. It has proven to be advantageous for to use the manufacture of the polypropylene broom body for which Production of the intermediate plate polyamide and for the production of the Base layer including the bristles a thermoplastically processable Rubber grade (TPE).

Die Zwischenplatte kann zumindest zwei nach oben vorstehende Haltelaschen aufweisen, die mit entsprechenden, den Besenkörper in Querrichtung durchdringenden Öffnungen in Deckung bringbar und gemeinsam mit diesen von Haltebolzen durchgriffen sind. Nach eingetretenem Verschleiß der Borstenbestückung ist es hierdurch ganz besonders einfach möglich, die verschlissene Borstenbestückung durch eine neue zu ersetzen.The intermediate plate can have at least two holding tabs projecting upwards have, with corresponding, the broom body in the transverse direction penetrating openings can be covered and together with these are penetrated by retaining bolts. After wear and tear Bristle assembly makes it particularly easy to do that to replace worn bristles with a new one.

Die Tragschicht kann in Umfangsrichtung von einem Wulst begrenzt sein, der den unteren Rand des Besenkörpers außenseitig umschließt. Hierdurch wird nicht nur verhindert, daß sich bei einer Anschlagberührung von Wänden oder Möbeln eine Beschädigung ergibt sondern zusätzlich das Eindringen von Schmutz in den Zwischenraum zwischen der Tragschicht und dem Besenkörper verhindert. Unter hygienischen Gesichtspunkten ist das von großem Vorteil.The base layer can be delimited in the circumferential direction by a bead which encloses the lower edge of the broom body on the outside. This will not only prevents that when touching walls or Furniture is damaged but additionally penetrates Dirt in the space between the base course and the Broom body prevented. From a hygienic point of view, this is from great advantage.

Die im Bereich der stirnseitigen Enden befindlichen Borsten der Borstenbestückung 2 werden dadurch in eine Lage überführt, die sie das stirnseitige Ende des Besenkörpers 1 um das Maß A übergreifen. Der Gummibesen läßt sich hierdurch ausgezeichnet zum Reinigen der Ecke zwischen einer ebenen Bodenfläche und einer senkrecht darauf stehenden Wänden benutzen.The bristle assembly 2 forms part of a deformable Base layer 4, which is produced in a flat shape and during its attachment the underside of the broom body 1 is deformed so that a continuous contact on the underside of the broom body 1 results at least along the circumferential edge. The in the field of Bristles of the bristle assembly 2 located at the front ends thereby transferred to a position which is the front end of the broom body 1 overlap by dimension A. This allows the rubber broom to be used excellent for cleaning the corner between a flat floor surface and use walls perpendicular to it.

Der in Figur 1 gezeigte Gummibesen ist so ausgebildet, daß die die Borstenbestückung 2 aufweisende Tragschicht 4 nur im Bereich der einander gegenüberliegenden, stirnseitigen Enden hochgezogen ist, wodurch nur in diesen beiden Bereichert seitlich überstehende Borsten der Borstenbestückung 2 verfügbar sind. Die Erfindung ist aber nicht auf diese Ausbildung beschränkt sondern umfaßt auch Ausführungen, bei denen der Besenkörper 1 in allen Richtungen von in seitlicher Richtung überstehenden Borsten der Borstenbestückung 2 umschlossen ist. Eine solche Ausbildung ist in Figur 2 in quergeschnittener Darstellung wiedergegeben. Die darin enthaltene, die Borstenbestückung 2 aufweisende Tragschicht 4 ist auf eine Zwischenplatte 5 aufgespannt, die auf dem ganzen Umfang in Richtung des Randes des Besenkörpers 1 hochgezogen und im mittleren Bereich konvex ausgebildet ist. Die Borsten der Borstenbestückung 2 stehen dadurch nicht nur analog Figur 1 in Längsrichtung über die beiden Enden des Besenkörpers 1 vor sondern zusätzlich beiderseits in seitlicher Richtung über die äußere Begrenzung des Besenkörpers 1 um das Maß B. Auch bei dieser Ausführung ist die Tragschicht 4 in ebener Form erzeugt und nachträglich durch Aufspannen auf die Zwischenplatte 5 in die gezeigte Form überführt. Die Tragschicht 4 ist formschlüssig an der Zwischenplatte 5 festgelegt. Zu diesem Zwecke ist sie oberseitig mit sich parallel zu ihrer Längsrichtung erstreckenden Vorsprüngen 7 von T-förmigem Profil versehen, wobei die Vorsprünge 7 in ihrem Querschnitt entsprechende, nach unten offene Aufnahmen der Zwischenplatte 5 eingefügt sind. Die Zwischenplatte 5 besteht aus Polypropylen. Sie ist mit vier nach oben stehenden Haltelaschen 8 versehen, die mit entsprechenden, den Besenkörper 1 in Querrichtung durchdringenden Öffnungen 6 in Deckung bringbar und gemeinsam mit diesen von Haltebolzen 9 durchdrungen sind. Die Haltebolzen 9 sind leicht entfernbar, was gestattet, die Borstenbestückung 2 nach eingetretenem Verschleiß durch eine neue zu ersetzen.The rubber broom shown in Figure 1 is designed so that the Bristle 2 base layer 4 only in the area of each other opposite, front ends is pulled up, whereby only in these two enriches laterally protruding bristles of the bristle assembly 2 are available. The invention is not limited to this training but also includes versions in which the broom body 1 in all Directions of bristles of the Bristle assembly 2 is enclosed. Such an embodiment is shown in FIG reproduced cross-sectional representation. The contained therein, the Base layer 4 having bristles 2 is on an intermediate plate 5 stretched across the entire circumference towards the edge of the Broom body 1 is pulled up and is convex in the central region. As a result, the bristles of the bristle assembly 2 are not only analogous to FIG. 1 but in the longitudinal direction over the two ends of the broom body 1 additionally on both sides in a lateral direction over the outer boundary of the Broom body 1 by dimension B. Also in this version is the base layer 4 created in a flat form and subsequently by clamping onto the The intermediate plate 5 is converted into the shape shown. The base layer 4 is positively attached to the intermediate plate 5. For this purpose it is on the top side with projections extending parallel to their longitudinal direction 7 provided by T-shaped profile, the projections 7 in their cross section corresponding, open downward shots of the intermediate plate 5 inserted are.
