Aus der FR 1 248 028 ist ein Gummibesen bekannt, bei dem ein Borstenteil um
einen Haltekörper herumgeführt ist, wobei sich die Borsten im Randbereich
vom Boden entfernt haben. Der Haltekörper ist hierzu an seinen äußeren
Enden hochgezogen.From
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 to develop further that corners are easier and safer to manufacture have 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
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 auf dem ganzen Umfang 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 that runs all the way towards the edge Scope 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 Profilen mit kreisförmigem Querschnitt gelangen bevorzugt solche mit rechteckigem Querschnitt 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 einen polygonförmigen, X- oder Y-förmigen Querschnitt zu geben. Hierdurch wird eine wesentlich verbesserte Reinigungswirkung erzielt. Der rückwärtige Bereich, d.h. die nicht vorspringenden Borsten kann ein Profil mit rundem Querschnitt haben, um eine gute Elastizität in allen Richtungen zur Verfügung zu haben. Die während der bestimmungsgemäßen Verwendung erzielte Reinigungswirkung läßt sich dadurch wesentlich ver-bessern. 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 profiles with circular cross-section are preferably rectangular Cross section for the application, which extend transversely to the cleaning direction. An overlapping, mutual assignment of the bristles has proven to be advantageous proven. If cylindrical designs are used, there is the additional possibility of bristles at least in the above area to give a polygonal, X- or Y-shaped cross section. hereby a significantly improved cleaning effect is achieved. The back one Area, i.e. the non-protruding bristles can have a round profile Cross section have good elasticity available in all directions to have. The achieved during the intended use This significantly improves the cleaning effect. An integration wiping lips in the bristle assembly is also possible, preferably in an arrangement in which every other row within the bristle assembly is formed by at least one wiper lip. A wiper lip can be used also several successive or laterally in the direction of movement spaced partial lips include those of limited length and on each other Gap are assigned. This increases the flexibility of the wiper lip improved overall. Regarding 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.

- A rubber brush according to claim 5, characterized in that the intermediate plate (5) has at least two upwardly projecting retaining lugs (8) which can be made to coincide with corresponding openings (6), passing through the brush body (1) in the transverse direction, and, together with said openings, have retaining pins (9) passing through them.
- A rubber brush according to any one of claims 1 to 6, characterized in that the bristle covering (2) comprises bristles which, in a projecting region, have a profile with polygonal, X-shaped or Y-shaped cross section.
- A rubber brush according to claim 7, characterized in that the bristle covering (2) comprises bristles which, in a non-projecting region, have a profile with a round cross section and, in the projecting region, have a profile with polygonal, X-shaped or Y-shaped cross section.
- A rubber brush according to any one of claims 1 to 8, characterized in that the bristles located in the region of the ends of the brush body (1) extend beyond the end of the brush body (1) by the distance A and the bristles in the region of the lateral outer boundaries extend beyond the latter on both sides by the distance B, B being less than A.
- A process for producing a rubber brush, the rubber brush comprising a brush body (1) with a bristle covering (2) which is arranged on the underside of the brush body, is made of an elastic polymer material and the constituent parts of which merge integrally one into the other, the bristles projecting laterally beyond the border of the brush body (1) and, when the brush is ready for use, the bristle ends being located in one plane, the brush body (1) being a moulding produced independently of the bristle covering (2) and having an underside which is raised in the direction of the border at both ends, and the bristle covering (2) forming a constituent part of a deformable carrying layer (4), which comes into abutting contact with the underside of the brush body (1) at least along the peripheral border, characterized in that in a first step the brush body (1) is produced, in that in another step the carrying layer (4) is produced in an essentially planar form with bristles arranged essentially perpendicularly on it, and in that in a further step the carrying layer (4) is mounted on the brush body (1), the bristles, which project essentially perpendicularly from the carrying layer (4), being displaced laterally outwards over the entire periphery in the raised region.
