Description

Borstenleiste bristle strip
Die Erfindung betrifft eine Borstenleiste für eine Staubsaugerdüse nach dem Oberbegriff von Anspruch 1.The invention relates to a bristle strip for a vacuum cleaner nozzle according to the preamble of claim 1.
Die Erfindung betrifft weiterhin eine Staubsaugerdüse.The invention further relates to a vacuum cleaner nozzle.
Die verschiedenen Staubsaugertypen gemäß dem Stand der Technik lassen sich prinzipiell in zwei unterschiedliche Bauformen unterteilen:The various vacuum cleaner types according to the prior art can in principle be divided into two different types:
Bei sogenannten Bodenstaubsaugern sind in einem zumeist auf Rollen gelagerten Gehäuse Motor, Gebläse, Filtereinheit und elektronische Einrichtungen angeordnet. Ein oft teleskopartig in der Länge verstellbares Saugrohr ist an einem Ende mittels eines flexiblen Saug- schlauchs mit dem Gehäuse beziehungsweise dem Gebläse des Bodenstaubsaugers verbunden und weist an seinem anderen Ende eine Bodendüse auf, die mit der zu reinigenden Oberfläche in Kontakt tritt.In so-called canister vacuum cleaners, the motor, blower, filter unit and electronic devices are arranged in a housing, which is usually mounted on rollers. An often telescopically adjustable in length suction pipe is connected at one end by means of a flexible suction hose with the housing or the blower of the vacuum cleaner and has at its other end a floor nozzle, which comes into contact with the surface to be cleaned.
Eine zweite Bauform bilden die sogenannten Handstaubsauger. Im Unterschied zu den Bodenstaubsaugern ist hier das Saugrohr starr mit dem Staubsaugergehäuse verbunden. Auch hier sind Motor, Gebläse, Elektrik und Filtereinheit in dem Gehäuse untergebracht. Dieses weist zusätzlich auf der dem Saugrohranschluss gegenüberliegenden Seite einen in Verlängerung des Saugrohrs angebrachten Stiel zur Handhabung auf.A second design form the so-called hand vacuum cleaner. In contrast to the cylinder vacuum cleaners here, the suction pipe is rigidly connected to the vacuum cleaner housing. Again, engine, blower, electrical and filter unit are housed in the housing. This additionally has on the side opposite the suction pipe connection on an extension of the suction pipe attached handle for handling.
Bei beiden Staubsaugertypen wird mittels einer Düse der von Motor und Gebläse erzeugte Unterdruck auf die zu reinigende Oberfläche übertragen. Dabei handelt es sich in der Regel entweder um harte, glatte Oberflächen von Bodenbelägen wie Parkett, PVC, Stein etc. oder um textile Oberflächen wie etwa Teppichböden, Möbelpolster oder dergleichen. Die unterschiedliche Beschaffenheit der Oberfläche stellt teilweise gegensätzliche Anforderungen an die Funktionalität von Düsen wie z.B. Bodendüsen, Polsterdüsen oder dergleichen. Bei strukturierten, luftdurchlässigen Oberflächen wie beispielsweise Teppichen ist in der Regel ein möglichst gutes Aufliegen der Bodendüse erwünscht, um eine tiefreichende und hohe Saugwirkung zu erzielen. Bei glatten Boden-Oberflächen hingegen reicht die unmittelbare Saugwirkung oft nicht aus, um festsitzende Schmutzpartikel von der Oberfläche zu lösen. Zudem besteht, je nach konstruktiver Ausführung, die Gefahr eines Festsaugens der Bodendüse an der Oberfläche und damit eventuell auch die einer Beschädigung des Bodenbelags durch Verkratzen.In both types of vacuum cleaner, the negative pressure generated by the motor and blower is transmitted to the surface to be cleaned by means of a nozzle. These are usually either hard, smooth surfaces of floor coverings such as parquet, PVC, stone, etc., or textile surfaces such as carpets, furniture upholstery or the like. The different nature of the surface makes partially conflicting demands on the functionality of nozzles such as floor nozzles, upholstery nozzles or the like. For structured, air-permeable surfaces such as carpets, the best possible contact with the floor nozzle is desirable in order to achieve a deep and high suction effect. For smooth floor surfaces, however, the direct suction is often not sufficient to release stuck dirt particles from the surface. moreover There is, depending on the design, the risk of a solid suction of the floor nozzle on the surface and thus possibly also a damage to the floor covering by scratching.
Düsen, insbesondere Bodendüsen, Polsterdüsen oder dergleichen, gemäß dem Stand der Technik sind deshalb in der Regel mit einer oder mit mehreren Borstenleisten ausgestattet. Diese sind so angeordnet, dass sich ihre Borsten von der Unterseite der Bodendüse, welche die zu reinigende Oberfläche kontaktiert, im Wesentlichen senkrecht zur Bodendüse in Richtung Boden erstrecken. Gewöhnlich sind diese Borsten mittels eines Fußschalters an der Bodendüse über eine Mechanik zwischen einer ausgefahrenen Stellung, in der die Borsten aus der Unterseite der Bodendüse hervorragen und so mit dem Bodenbelag in Kontakt treten können und gegebenenfalls einen Abstand zwischen Düse und Bodenbelag erzeugen, sowie einer versenkten Stellung, in der sie im Wesentlichen funktionslos in die Bodendüse eingefahren sind, schaltbar.Nozzles, in particular floor nozzles, upholstery nozzles or the like, according to the prior art are therefore usually equipped with one or more bristle strips. These are arranged so that their bristles extend from the underside of the floor nozzle, which contacts the surface to be cleaned, substantially perpendicular to the floor nozzle in the direction of the floor. Usually, these bristles are by means of a foot switch on the floor nozzle via a mechanism between an extended position in which the bristles protrude from the bottom of the floor nozzle and so can come into contact with the floor covering and optionally create a distance between the nozzle and floor covering, as well as a sunk Position in which they are essentially retracted without function in the floor nozzle, switchable.
Auf diese Weise wird im ausgefahrenen Zustand eine Bürstwirkung auf die zu reinigende Oberfläche ausgeübt und festsitzender Schmutz von der zu reinigenden Oberfläche abgelöst, der dann abgesaugt werden kann. Durch den vergrößerten Abstand zwischen Düse und Oberfläche wird auch ein ausreichend großer Luftstrom seitlich in die Düse ermöglicht und ein Festsaugen der Düse auf der zu reinigenden Oberfläche beziehungsweise ein Verkratzen der Oberfläche im Fall der Bodenreinigung verhindert. Im eingefahrenen Zustand hingegen steht ein genügend großer Unterdruck für das Reinigen von textilen Oberflächen zur Verfügung.In this way, in the extended state, a brushing action is exerted on the surface to be cleaned and fixed dirt is removed from the surface to be cleaned, which can then be sucked off. Due to the increased distance between the nozzle and the surface, a sufficiently large air flow is also made possible laterally into the nozzle and prevents the nozzle from adhering to the surface to be cleaned or scratching the surface in the case of floor cleaning. In the retracted state, however, there is a sufficiently large negative pressure for the cleaning of textile surfaces available.
Bodendüsen gemäß dem Stand der Technik sind in der Regel mit einer separaten Borstenleiste ausgestattet, die aus drei Teilen besteht: einer Metallschiene, einem Einlegedraht sowie Polyamidborsten. Diese drei Elemente müssen in mehreren Montage- und Fertigungsschritten zu einer funktionsfähigen Borstenleiste zusammengefügt werden. Diese Montage ist zeit- und kostenaufwändig.Prior art floor jets are typically equipped with a separate bristle bar that consists of three parts: a metal rail, an insert wire and polyamide bristles. These three elements must be assembled in several assembly and manufacturing steps to form a functional bristle strip. This assembly is time consuming and costly.
Darüber hinaus sind Borstenleisten bekannt, die einteilig aus einem Material hergestellt sind. Diese sind zwar einfach zu fertigen, es muss aber zwischen den unterschiedlichen Anforde- rungen, welche die Borsten einerseits und der Borstenleistenrücken andererseits stellen, ein Kompromiss gefunden werden.In addition, bristle strips are known, which are made in one piece from a material. Although these are easy to manufacture, they have to be differentiated between the different requirements. ments, which represent the bristles on the one hand and the bristle backs on the other hand, a compromise can be found.
Es ist eine Aufgabe der Erfindung, eine einteilige Borstenleiste für eine Staubstaugerdüse zur Verfügung zu stellen, die einfach und kostengünstig hergestellt werden kann und die hinsichtlich ihrer Funktionalität optimiert ist.It is an object of the invention to provide a one-piece bristle strip for a Staubstaugerdüse which can be produced easily and inexpensively and which is optimized in terms of their functionality.
Diese Aufgabe wird mit den Merkmalen der unabhängigen Ansprüche gelöst.This object is achieved with the features of the independent claims.
Vorteilhafte Ausführungsformen der Erfindung sind in den abhängigen Ansprüchen angegeben.Advantageous embodiments of the invention are indicated in the dependent claims.
Die Erfindung baut auf der gattungsgemäßen Borstenleiste dadurch auf, dass das Trägerelement zumindest teilweise aus einer Hartkomponente und die Borsten zumindest teilweise aus einer Weichkomponente bestehen. Die Wahl von Komponenten mit unterschiedlichen Härtegraden für unterschiedliche Bereiche der Borstenleiste stellt eine Optimierung derselben hinsichtlich der Funktionalität dar. Beispielsweise können die Trägerelementbereiche aus PP, PP-GF oder dergleichen hergestellt werden. Die Borstenelementbereiche hingegen können beispielsweise aus TPE, PVC, Silikon, Elastomer oder ähnlichem gefertigt werden. Damit sind die tragenden Bereiche der Borstenleiste hinsichtlich ihrer tragenden Funktionalität optimiert, gleichzeitig können die Borsten ausreichend flexibel sein. Zusätzlich entfallen auf diese Weise nach der Herstellung der Borstenleiste weitere Montageschritte, wie etwa das Anbringen zusätzlicher Versteifungselemente, was eine Kosteneinsparung ermöglicht. Des Weiteren kann auf zusätzliche Montagewerkzeuge verzichtet werden. Gegebenenfalls geht mit der Einstückigkeit aufgrund eines Fehlens von Verbindungen und Verbindungsmaterialien, wie etwa Klebstoffen, eine höhere Zuverlässigkeit der Borstenleiste einher.The invention is based on the generic bristle strip in that the carrier element consists at least partially of a hard component and the bristles at least partially made of a soft component. The choice of components with different degrees of hardness for different regions of the bristle strip represents an optimization of the same in terms of functionality. For example, the carrier element regions of PP, PP-GF or the like can be produced. The bristle element areas, however, can be made of TPE, PVC, silicone, elastomer or the like, for example. Thus, the bearing areas of the bristle strip are optimized in terms of their supporting functionality, while the bristles can be sufficiently flexible. In addition, this eliminates after the manufacture of the bristle strip further assembly steps, such as the attachment of additional stiffening elements, which allows a cost savings. Furthermore, can be dispensed with additional assembly tools. Optionally, the integrity due to a lack of joints and bonding materials, such as adhesives, increases the reliability of the bristle molding.
Bei einer bevorzugten Ausführungsform ist vorgesehen, dass die Borsten an das Trägerelement in einem Spritzgussverfahren angespritzt sind. Mit Hilfe des Spritzgussverfahrens können die Borsten besonders einfach und kostengünstig an das Trägerelement angeformt und so die Einteiligkeit erreicht werden. - A -In a preferred embodiment it is provided that the bristles are injection-molded onto the carrier element in an injection molding process. With the help of the injection molding process, the bristles can be particularly easily and inexpensively molded to the support element and so the one-piece can be achieved. - A -
Bei einer ebenfalls vorteilhaften Ausführungsform ist vorgesehen, dass die Borsten im Wesentlichen kegelförmig sind. Dabei ist insbesondere vorgesehen, dass die breitere Kegelbasis den Anbindungspunkt der Borsten an das Trägerelement bildet und die gegebenenfalls auch stumpfe Kegelspitze der zu reinigenden Oberfläche zugewandt ist. Auf diese Weise kann eine ausreichende Flexibilität und Luftdurchlässigkeit der Borsten erreicht werden, während gleichzeitig für eine ausreichend stabile Anformung der Borsten an das Trägerelement gesorgt ist.In a likewise advantageous embodiment, it is provided that the bristles are substantially conical. In this case, provision is made in particular for the wider cone base to form the attachment point of the bristles to the carrier element and for the optionally also blunt conical tip to face the surface to be cleaned. In this way, a sufficient flexibility and air permeability of the bristles can be achieved, while at the same time ensuring a sufficiently stable formation of the bristles on the support element.
Des Weiteren kann vorteilhaft vorgesehen sein, dass die Borstenenden abgerundet sind. Dies erhöht die Lebensdauer der Borsten und damit auch die der Borstenleiste und schont empfindliche Oberflächen bei deren Reinigung.Furthermore, it can be advantageously provided that the bristle ends are rounded. This increases the service life of the bristles and thus also of the bristle strip and protects sensitive surfaces during their cleaning.
Bei einer weiteren Ausführungsform kann vorgesehen sein, dass die Borsten in mehreren Reihen und/oder zueinander versetzt angeordnet sind. Dies ermöglicht eine ausreichend dichte Besetzung des Trägerelements mit Borsten bei einer gleichzeitig optimalen Beweglichkeit der Borsten zu- und gegeneinander.In a further embodiment it can be provided that the bristles are arranged in a plurality of rows and / or offset from each other. This allows a sufficiently dense occupation of the carrier element with bristles with a simultaneously optimal mobility of the bristles on and against each other.
Die Erfindung betrifft außerdem eine Staubsaugerbodendüse mit einer erfindungsgemäßen Borstenleiste. Auf diese Weise können die Vorteile der erfindungsgemäßen Borstenleiste auch im Rahmen einer Staubsaugerbodendüse verwirklicht werden.The invention also relates to a Staubsaugerbodendüse with a bristle strip according to the invention. In this way, the advantages of the bristle strip according to the invention can also be realized in the context of a Staubsaugerbodendüse.
Der Erfindung liegt die Erkenntnis zugrunde, dass bei einer Herstellung der Borstenleiste für eine Staubsaugerbodendüse aus zumindest zwei Komponenten mit unterschiedlicher Härte erhebliche Montagekosten eingespart werden können und gleichzeitig die Funktionalität der Borstenleiste verbessert werden kann. Dabei kann die vorliegende Erfindung bei allen gängigen Staubsaugertypen eingesetzt werden.The invention is based on the finding that in a production of the bristle strip for a Staubsaugerbodendüse from at least two components with different hardness considerable installation costs can be saved and at the same time the functionality of the bristle strip can be improved. The present invention can be used in all common types of vacuum cleaner.
Die Erfindung wird nun mit Bezug auf die begleitenden Zeichnungen anhand einer besonders bevorzugten Ausführungsform beispielhaft erläutert.The invention will now be described by way of example with reference to the accompanying drawings with reference to a particularly preferred embodiment.

Figur 1 zeigt eine perspektivische Darstellung der erfindungsgemäßen Borstenleiste 10. Die Borstenleiste 10 weist ein Trägerelement 12 auf. Dieses ist in einem 2K-Spritzgussverfahren aus einer Hartkomponente, wie beispielsweise PP oder PP-GF hergestellt. An das Trägerelement 12 sind in vier Längsreihen je vierzig beziehungsweise neununddreißig Borsten 14 angespritzt. Diese bestehen aus einer Weichkomponente, wie etwa TPE, PVC, Silikon oder Elastomer.FIG. 1 shows a perspective view of the bristle strip 10 according to the invention. The bristle strip 10 has a carrier element 12. This is made in a 2K injection molding process from a hard component such as PP or PP-GF. Forty or thirty-nine bristles 14 are molded onto the carrier element 12 in four longitudinal rows. These consist of a soft component, such as TPE, PVC, silicone or elastomer.

In particular, FIG. 2a shows a longitudinal section through the bristle strip 10 along its axis A, perpendicular to the orientation of the bristles 14. FIG. 2b shows a longitudinal section along the axis A of the bristle strip 10 along the orientation of the bristles 14. Figure 2c shows an enlarged detail of Figure 2b, as indicated by the dash-dotted circles.

The sectional view extends perpendicular to the axis A of the bristle strip 10.
Aufgrund des 2K-Spritzgussverfahrens besteht das Trägerelement 12 aus einem steifen Material und kann so die Kräfte aufnehmen und weitergeben, die bei einem Ausfahren beziehungsweise Einfahren der Borstenleiste an der Unterseite der Staubsaugerbodendüse auftreten. Gleichzeitig kann durch die weiche Komponente der Borsten 14 eine Flexibilität derselben erreicht werden. Durch die konische beziehungsweise kegelförmige Ausgestaltung der Borsten 14 wird ein ausreichend großer Übergangsbereich zwischen Borsten 14 und Trägerelement 12 bereitgestellt. Die Enden 16 der Borsten 14 sind abgerundet. Gleichzeitig erlaubt die Anordnung der Borsten 14 einen ausreichend hohen Luftstrom zwischen den einzelnen Borsten 14. Die in der vorstehenden Beschreibung, in den Zeichnungen, sowie in den Ansprüchen offenbarten Merkmale der Erfindung können sowohl einzeln als auch in beliebiger Kombination für die Verwirklichung der Erfindung wesentlich sein.Due to the 2K injection molding process, the support member 12 is made of a rigid material and can thus absorb and pass on the forces that occur during an extension or retraction of the bristle strip on the underside of the Staubsaugerbodendüse. At the same time, flexibility of the bristles 14 can be achieved by the soft component. Due to the conical or cone-shaped configuration of the bristles 14, a sufficiently large transition region between bristles 14 and carrier element 12 is provided. The ends 16 of the bristles 14 are rounded. At the same time, the arrangement of the bristles 14 allows a sufficiently high air flow between the individual bristles 14. The features of the invention disclosed in the foregoing description, in the drawings and in the claims may be essential to the realization of the invention either individually or in any combination.
