Description

Die Erfindung betrifft ein Verfahren zum Herstellen einer Bürste, insbesondere einer Rundbürste, mit einem Borstenteil und einem Träger, in den das Borstenteil ragt und in dem es befestigt ist, wobei das Borstenteil über miteinander verdrillte Drahtabschnitte befestigte Borsten aufweist.The invention relates to a method for producing a brush, in particular a round brush, with a bristle part and a carrier, in which the bristle part protrudes and in which it is fixed, wherein the bristle part has bristles fastened via twisted wire sections.

Darüber hinaus betrifft die Erfindung eine Vorrichtung zur Herstellung einer Bürste sowie eine Bürste selbst.Moreover, the invention relates to a device for producing a brush and a brush itself.

Insbesondere bezieht sich die Erfindung auf das Herstellungsverfahren und eine Vorrichtung zur Herstellung einer Rundbürste sowie eine Rundbürste selbst.In particular, the invention relates to the manufacturing method and an apparatus for producing a round brush and a round brush itself.

Sogenannte gedrehte Rundbürsten besitzen einen Borstenteil, der einerseits aus den Borsten und andererseits aus einem Draht besteht, bei dem Abschnitte miteinander verdrillt sind. Zwischen den verdrillten Drahtabschnitten werden Borsten mittig geklemmt, die dann abstehende Enden aufweisen.So-called turned round brushes have a bristle part, which consists on the one hand of the bristles and on the other hand of a wire, in which sections are twisted together. Between the twisted wire sections bristles are clamped in the middle, which then have projecting ends.

Derartige Bürsten werden insbesondere als Miniaturbürsten eingesetzt, hierbei vor allem als Interdentalbürsten und Mascarabürsten. Der Draht, dessen Abschnitte miteinander verdrillt werden, weist dabei einen Durchmesser von unter 1 mm, bei Interdentalbürsten von wenigen Zehntel Millimetern auf. Insbesondere bei Interdentalbürsten ist es wichtig, dass der Borstenteil sicher im Träger verankert ist. Damit wird ausgeschlossen, dass beim Verklemmen der Interdentalbürste zwischen nahe zueinander stehenden Zähnen sich der Träger vom Borstenteil lösen kann.Such brushes are used in particular as miniature brushes, especially as interdental brushes and mascara brushes. The wire, whose sections are twisted together, has a diameter of less than 1 mm, with interdental brushes of a few tenths of a millimeter. Especially with interdental brushes, it is important that the bristle part is securely anchored in the carrier. This eliminates the possibility of the carrier separating from the bristle part when the interdental brush is jammed between teeth that are close to each other.

Bisherige Miniaturbürsten werden so hergestellt, dass das Borstenteil, welches einen Borstenabschnitt sowie ein trägerseitiges, borstenfreies Ende hat, mit diesem trägerseitigen Ende in einem Loch des Trägers verklebt wird, bei der Herstellung des Trägers umspritzt wird oder durch Verschmelzen oder Schweißen nach einer Induktiverwärmung des Trägers formschlüssig in diesen eingebettet wird.Previous miniature brushes are made so that the bristle portion, which has a bristle portion and a carrier-side, bristle-free end, is glued to this carrier-side end in a hole of the carrier is encapsulated in the manufacture of the carrier or by fusing or welding after an inductive heating of the carrier is positively embedded in these.

Darüber hinaus gibt es aber auch Ansätze, das trägerseitige Ende des Borstenteils in ein Loch des Trägers einzuführen, über eine seitliche Öffnung im Träger das Borstenteil zu deformieren und anschließend die inneren Hohlräume auszuspritzen oder zu verkleben, um einen Formschluss zu erreichen.In addition, however, there are also approaches to introduce the carrier-side end of the bristle part in a hole of the carrier, to deform the bristle part via a lateral opening in the carrier and then eject or glue the inner cavities to achieve a positive fit.

Schließlich gibt es noch bei Interdentalzahnbürsten sogenannte Wechselbürsten, bei denen der Träger einen Stiel oder Griff bildet, der mit einer verriegelbaren und entriegelbaren Befestigungseinrichtung für das trägerseitige Ende des Borstenteils ausgestattet ist. Hier wird beispielsweise das Borstenteil mit seinem trägerseitigen Ende in eine Öffnung eingeführt und anschließend über einen schwenkbaren Hebel gleichzeitig um 90° abgeknickt und geklemmt.Finally, there are so-called change brushes in interdental toothbrushes, in which the carrier forms a handle or handle, which is equipped with a lockable and unlockable fastening means for the carrier-side end of the bristle part. Here, for example, the bristle part is inserted with its carrier-side end in an opening and then bent over a pivotable lever at the same time by 90 ° and clamped.

Aufgabe der Erfindung ist es, ein Verfahren zum Herstellen einer Bürste, insbesondere einer Rundbürste, zu schaffen, das einerseits kostengünstig ist und andererseits eine sichere Fixierung des Bürstenteils im Träger sicherstellt.The object of the invention is to provide a method for producing a brush, in particular a round brush, on the one hand is inexpensive and on the other hand ensures a secure fixation of the brush part in the carrier.

Darüber hinaus soll eine kostengünstige Vorrichtung zur Herstellung einer Bürste angegeben werden sowie eine kostengünstige Bürste selbst.In addition, a cost-effective device for producing a brush is to be specified as well as a cost-effective brush itself.

Die oben genannte Aufgabe wird bei einem Verfahren der eingangs genannten Art durch folgende Schritte gelöst:

  • Vorsehen eines Ankerteils am trägerseitigen Ende des Borstenteils und, anschließend,
  • gemeinsames Einstoßen des Ankerteils und des trägerseitigen Endes des Borstenteils in ein Loch im Träger unter Verformung der Lochwand durch das Ankerteil zur unlösbaren Verankerung des Borstenteils im Träger.
The above object is achieved in a method of the type mentioned by the following steps:
  • Providing an anchor part at the carrier-side end of the bristle part and, subsequently,
  • joint collision of the anchor part and the carrier-side end of the bristle part in a hole in the carrier under deformation of the hole wall by the anchor part for permanent anchoring of the bristle part in the carrier.

Beim erfindungsgemäßen Verfahren wird der Draht im Träger mittels eines separaten Ankerteils fixiert. Diese Fixierung erfolgt durch das Ankerteil selbst, welches ein Übermaß gegenüber dem Loch aufweist und die Lochwand verformt. Das Ankerteil kann dabei auch die Lochwand teilweise plastisch verformen, wie es bei der bevorzugten Ausführungsform der Fall ist. Auch ein Einschneiden des Ankerteils in die Lochwand ist als plastisches Verformen zu verstehen. Bei der Erfindung kommt es zu einer unlösbaren Verankerung des Borstenteils im Träger, das heißt, die beiden Teile können nur gewaltsam oder durch Zerstörung voneinander getrennt werden.In the method according to the invention, the wire is fixed in the carrier by means of a separate anchor part. This fixation is carried out by the anchor part itself, which has an excess over the hole and deforms the hole wall. The anchor part can also partially plastically deform the hole wall, as is the case in the preferred embodiment. Also a cutting of the Anchor parts in the hole wall is to be understood as a plastic deformation. In the invention, there is an insoluble anchoring of the bristle part in the carrier, that is, the two parts can be separated only by force or by destruction.

Gemäß der bevorzugten Ausführungsform wird das Ankerteil ausschließlich durch das Einstoßen im Träger verankert, es sind keine weiteren Verfahrensschritte zur zusätzlichen Sicherung des Borstenteils im Träger nachgeschaltet.According to the preferred embodiment, the anchor part is anchored exclusively by the impact in the carrier, there are no further process steps for additional securing of the bristle part in the carrier downstream.

Zur Befestigung des Ankerteils am Draht wird zumindest ein Drahtabschnitt, vorzugsweise aber beide miteinander verdrillte Drahtabschnitte, am trägerseitigen Ende gebogen. Im gebogenen Ende wird dann das Ankerteil aufgenommen.For attachment of the anchor part to the wire, at least one wire section, but preferably both twisted wire sections, is bent at the carrier-side end. In the bent end of the anchor part is then added.

Optional kann es dabei bevorzugt sein, dass beim Einstoßen das Ankerteil das Borstenteil mitnimmt und es im Träger klemmt. Durch das umgebogene Ende ist in Auszugsrichtung eine zusätzliche formschlüssige Sicherung erreicht.Optionally, it may be preferred that upon impact, the anchor part entrains the bristle part and clamps it in the carrier. By the bent end an additional positive locking is achieved in the extension direction.

Das trägerseitige Ende des Borstenteils kann U-förmig oder zur Bildung einer geschlossenen oder fast geschlossenen Schlaufe gebogen sein.The wearer-side end of the bristle portion may be U-shaped or bent to form a closed or almost closed loop.

Als Ankerteil wird beispielsweise ein Ankerplättchen, insbesondere ein flaches Ankerplättchen verwendet, welches sich quer zur Stoßrichtung erstreckt.As an anchor part, for example, an anchor plate, in particular a flat anchor plate is used which extends transversely to the impact direction.

Alternativ hierzu kann das Ankerteil bogenförmig verlaufen und abstehende Füße haben. Somit wäre es möglich, das Ankerteil als Stanzteil auszuführen oder als gebogenen Haltedraht. Auch hier können Widerhaken oder dergleichen vorgesehen sein.Alternatively, the anchor part may be arcuate and have protruding feet. Thus, it would be possible to perform the anchor part as a stamped part or as a curved retaining wire. Again, barbs or the like may be provided.

Eine bevorzugte Ausführungsform sieht vor, dass das Ankerteil als Schlinge ausgeführt ist, die durch einen gebogenen Draht gebildet wird.A preferred embodiment provides that the anchor part is designed as a loop, which is formed by a bent wire.

Insbesondere wird das Ankerteil, wenn es abstehende Füße oder abstehende Enden hat, mit diesen voraus in das Loch gedrückt.In particular, the anchor part, if it has protruding feet or protruding ends, with these pressed ahead in the hole.

Wie bereits erwähnt, wird das erfindungsgemäße Verfahren vorzugsweise zum Herstellen einer Miniaturbürste, insbesondere in Form einer Mascara- oder Interdentalbürste eingesetzt. Solche Bürsten haben einen maximalen Durchmesser im Bürstenabschnitt von weniger als 10 mm.As already mentioned, the method according to the invention is preferably used for producing a miniature brush, in particular in the form of a mascara or interdental brush. Such brushes have a maximum diameter in the brush section of less than 10 mm.

Die Drahtabschnitte werden, damit möglichst keine freien, scharfen Enden abstehen, aus zwei ineinander übergehenden Drahthälften gebildet. Die freien Enden des Drahtes liegen nach der Befestigung vollständig innerhalb des Trägers, stehen also nicht aus diesem heraus. Es ist in diesem Bereich auch keine Nachbearbeitung, zum Beispiel durch Zuschnitt des aus dem Träger herausstehenden Endes notwendig, denn, wie bereits erwähnt, sollen die beiden freien Enden der Drahtabschnitte komplett im Träger liegen.The wire sections are formed so that as possible no free, sharp ends protrude from two merge into one another wire halves. The free ends of the wire lie completely inside the carrier after attachment, So do not stand out of this. It is in this area no rework, for example, by cutting the protruding from the carrier end necessary, because, as already mentioned, the two free ends of the wire sections are completely in the carrier.

Bevorzugt ist der Träger gleich das Griffteil selbst. Als Alternative hierzu könnte der Träger auch in einem Griffteil lösbar und damit austauschbar temporär arretierbar sein.Preferably, the carrier is the same as the handle part itself. Alternatively, the carrier could also be detachable and temporarily lockable in a handle part.

Der Träger sollte stirnseitig ein Loch aufweisen, in dem das Borstenteil befestigt wird.The carrier should have a frontal hole in which the bristle part is attached.

Dabei wird bevorzugt nur ein einziges Borstenteil im Träger befestigt, sodass die Bürste sehr filigran ausgeführt ist.In this case, preferably only a single bristle part is fixed in the carrier, so that the brush is made very filigree.

Das Ankerteil kann in die seitliche Lochwand oder in den Lochboden eingedrückt werden. Insbesondere bei der Ausführungsform mit einer Schlinge als Ankerteil wird dieses in den Lochboden eingedrückt.The anchor part can be pressed into the side hole wall or into the hole bottom. In particular, in the embodiment with a loop as the anchor part of this is pressed into the hole bottom.

Eine weitere Ausführungsform der Erfindung sieht vor, dass nicht nur radial abstehende Borsten vorgesehen sind, sondern zusätzlich im Wesentlichen parallel zum trägerseitigen Ende des verdrillten Drahtabschnitts verlaufende Borsten vorhanden sind. Diese Borsten sind ebenfalls im Loch befestigt und ragen aus ihm heraus. Die Befestigung der Borsten erfolgt vorzugsweise ebenfalls über das Ankerteil, insbesondere ist eine solche Befestigung sehr einfach bei der Ausführungsform mit dem als Schlinge ausgebildeten Ankerteil. Hier lassen sich Borsten in der Schlinge fassen, sodass ihre beiden Enden parallel aus dem Loch heraus verlaufen.A further embodiment of the invention provides that not only radially projecting bristles are provided, but additionally bristles extending substantially parallel to the carrier-side end of the twisted wire section are present. These bristles are also mounted in the hole and protrude out of it. The attachment of the bristles is preferably also via the anchor part, in particular, such attachment is very simple in the embodiment with the anchor part designed as a loop. Here, bristles can be held in the loop so that their two ends run parallel out of the hole.

Die zusätzlichen Borsten erstrecken sich zu den radial abstehenden Borsten, ohne zwischen sie hineinzuragen. Durch die zusätzlichen Borsten lässt sich insbesondere bei Interdentalbürsten eine neue Art von Reinigung erreichen, indem nämlich die radialen Borsten zwischen den benachbarten Zähnen reinigen, wogegen die zusätzlichen Borsten die einwärts verlaufende Vertiefung zwischen benachbarten Zähnen und dem Zahnfleisch reinigen.The additional bristles extend to the radially protruding bristles without protruding between them. The extra bristles provide a new way of cleaning, especially with interdental brushes, by cleaning the radial bristles between the adjacent teeth, while the additional bristles clean the inward depression between adjacent teeth and the gum.

Die vorgenannte Aufgabe wird auch durch eine Vorrichtung zur Herstellung einer Bürste, insbesondere einer Rundbürste gelöst, die einen Träger und ein im Träger befestigtes Borstenteil aufweist. Das Borstenteil hat über miteinander verdrillte Drahtabschnitte fixierte Borsten und dient insbesondere zur Durchführung des vorgenannten Verfahrens. Mittels einer Halterung für den Träger und einer Zustelleinrichtung lassen sich Borstenteil und Träger miteinander verbinden. Die Zustelleinrichtung sorgt für eine lineare Relativbewegung zwischen Träger einerseits und Borstenteil sowie einem mit dem Borstenteil verbundenen Ankerteil andererseits. Bei dieser Zustellbewegung wird das Borstenteil samt Ankerteil in dem Träger unlösbar befestigt.The aforementioned object is also achieved by a device for producing a brush, in particular a round brush, which has a carrier and a bristle part fastened in the carrier. The bristle part has fixed bristles via twisted wire sections and serves in particular for implementation the aforementioned method. By means of a holder for the carrier and a delivery device, bristle part and carrier can be connected to each other. The feed device ensures a linear relative movement between the carrier on the one hand and the bristle part and an anchor part connected to the bristle part on the other. In this feed movement, the bristle part and anchor part in the carrier is permanently attached.

Obwohl natürlich auch der Träger relativ zu dem feststehenden Borstenteil bewegt werden kann, ist es bei der bevorzugten Ausführungsform umgekehrt vorgesehen, indem nämlich nur das Borstenteil samt Ankerteil bewegt wird und in den stehenden Träger eindringt.Although, of course, the carrier can be moved relative to the fixed bristle part, it is provided in the preferred embodiment vice versa, namely, only the bristle part is moved together with anchor part and penetrates into the stationary support.

Die erfindungsgemäße Bürste, die insbesondere als Rundbürste ausgeführt ist, weist einen Träger, ein im Träger aufgenommenes und befestigtes Borstenteil, das über miteinander verdrillte Drahtabschnitte fixierte Borsten besitzt, auf. Das Borstenteil ist über ein an seinem trägerseitigen Ende angebrachtes Ankerteil in einem Loch des Trägers unlösbar befestigt, wie zuvor bereits anhand des Verfahrens erläutert.The brush according to the invention, which is designed in particular as a round brush, has a carrier, a bristle part received and fastened in the carrier, which has fixed bristles via twisted-together wire sections. The bristle part is permanently fastened in a hole in the carrier by means of an anchor part attached to its carrier-side end, as already explained above with reference to the method.

Die Lochwand wird gemäß der bevorzugten Ausführungsform durch das Ankerteil plastisch verformt, um dadurch im Träger verankert zu sein. Unter plastischem Verformen ist in diesem Zusammenhang natürlich auch ein Einschneiden zu verstehen. Die erfindungsgemäße Bürste kann optional auch die im Zusammenhang mit dem Verfahren genannten Eigenschaften aufweisen, wie sie zuvor beschrieben und in den Unteransprüchen angegeben sind.The hole wall is plastically deformed by the anchor part according to the preferred embodiment, to thereby be anchored in the carrier. Under plastic deformation is in this context, of course, a cut to understand. The brush according to the invention may optionally also have the properties mentioned in connection with the method, as described above and indicated in the subclaims.

In Figur 1 ist eine Vorrichtung zur Herstellung einer Bürste 10 stilisiert dargestellt. Die Bürste 10 ist als Rundbürste ausgeführt und umfasst einen Träger 12, der vorzugsweise als langgestreckter Körper ausgeführt ist und gleichzeitig das Griffteil bildet.In FIG. 1 a device for producing a brush 10 is shown stylized. The brush 10 is designed as a round brush and comprises a support 12, which is preferably designed as an elongated body and at the same time forms the handle part.

Stirnseitig besitzt der Träger 12 ein Loch 14, in dem ein sogenanntes Borstenteil 16 befestigt ist.The end face of the carrier 12 has a hole 14 in which a so-called bristle part 16 is attached.

Das Borstenteil 16 ist ein sogenanntes gedrehtes Borstenteil mit einem Draht 18, dessen zwei Hälften miteinander verdrillt werden. Zwischen den verdrillten Drahtabschnitten werden Borsten 20 geklemmt. Das Borstenteil 16 umfasst somit einen mit den Borsten 20 versehenen Abschnitt 22 sowie einen borstenfreien, trägerseitigen Abschnitt 24.The bristle part 16 is a so-called twisted bristle part with a wire 18, the two halves of which are twisted together. Between the twisted wire sections bristles 20 are clamped. The bristle part 16 thus comprises a section 22 provided with the bristles 20 and a bristle-free, carrier-side section 24.

Der borstenseitige Abschnitt 24 ist an seinem trägerseitigen Ende gebogen, vorzugsweise zu einem U oder zu einer geschlossenen Schlaufe. Das gebogene trägerseitige Ende trägt das Bezugszeichen 26.The bristle-side portion 24 is bent at its wearer-side end, preferably to a U or to a closed loop. The curved carrier-side end bears the reference numeral 26.

In dem trägerseitigen, gebogenen Ende 26 wird ein Ankerteil 28, hier ein sogenanntes Ankerplättchen, aufgenommen.In the carrier-side, curved end 26, an anchor member 28, here a so-called anchor plate recorded.

Mit diesem Ankerplättchen 28, dessen Breite größer als der Durchmesser des Lochs 14 ist, wird das Borstenteil 16 mit dem Träger 12 verbunden.With this anchor plate 28, whose width is greater than the diameter of the hole 14, the bristle portion 16 is connected to the carrier 12.

Diese Arretierung des Borstenteils 16 am Träger 12 erfolgt durch eine Relativbewegung zwischen den beiden Einheiten, nämlich dem Träger 12 einerseits und dem Borstenteil 16 samt Ankerteil 28 andererseits.This locking of the bristle part 16 on the carrier 12 is effected by a relative movement between the two units, namely the carrier 12 on the one hand and the bristle part 16 together with the anchor part 28 on the other.

Beim hier dargestellten Beispiel werden das Borstenteil 16 samt Ankerteil 28 in das Loch 14 hineingestoßen. Zu diesem Zweck besitzt die Vorrichtung einen linear verfahrbaren Werkzeugkopf als Zustelleinrichtung 30, die Ankerteil 28 und Borstenteil 16 hält und das Ankerteil 28 und damit auch das Borstenteil 16 in das Loch 14 stößt.In the example shown here, the bristle part 16 together with the anchor part 28 are pushed into the hole 14. For this purpose, the device has a linear movable tool head as a delivery device 30, the anchor member 28 and bristle part 16 holds and the anchor member 28 and thus also the bristle member 16 abuts in the hole 14.

Bei dieser linearen Zustellbewegung drückt sich das Ankerteil 28 in die Lochwand 32, um diese plastisch zu verformen, insbesondere um sich in diese einzuschneiden.In this linear feed movement, the anchor member 28 presses into the hole wall 32 in order to plastically deform, in particular in order to cut into it.

Das Loch 14 ist in der dargestellten Ausführungsform übertrieben groß gezeichnet.The hole 14 is drawn exaggerated in the illustrated embodiment.

Die Vorschubbewegung ist so lang, dass das freie, spitze Ende des Borstenteils 16 nicht mehr aus dem Loch 14 heraussteht und, vorzugsweise, die Borsten 20 nicht in das Loch 14 hineinragen.The feed movement is so long that the free, pointed end of the bristle part 16 no longer protrudes from the hole 14 and, preferably, the bristles 20 do not protrude into the hole 14.

Eine Nachbearbeitung des Borstenteils 16, vor allem des trägerseitigen Endes 26, ist nicht erforderlich.A post-processing of the bristle portion 16, especially the carrier-side end 26 is not required.

Darüber hinaus ist gemäß der bevorzugten Ausführungsform eine zusätzliche Sicherung des Borstenteils 16 im Träger 12, zum Beispiel durch ein Umspritzen, Verkleben oder Erwärmen des Trägers 12 überflüssig.Moreover, according to the preferred embodiment, additional securing of the bristle portion 16 in the carrier 12, for example by overmolding, gluing or heating of the carrier 12 is unnecessary.

Zur Halterung des Trägers 12 besitzt die Vorrichtung eine lösbare Halterung 34.For holding the carrier 12, the device has a releasable holder 34th

Die Vorrichtung ist insbesondere eine vollautomatisch arbeitende Vorrichtung, z.B. ein Bearbeitungszentrum, in dem die Zustelleinrichtung 30 mit einer Zuführeinrichtung für die Borstenteile 16 einerseits und die Ankerteile 28 andererseits ausgestattet ist. Kurz vor der Stoßbewegung werden Borstenteil 16 und Ankerteil 28 zugeführt und zueinander positioniert, um dann gemeinsam in den Träger 12 hineingestoßen zu werden.In particular, the device is a fully automatic device, e.g. a machining center in which the feed device 30 is equipped with a supply device for the bristle parts 16 on the one hand and the anchor parts 28 on the other hand. Shortly before the thrust movement bristle part 16 and anchor member 28 are supplied and positioned to each other, to then be pushed into the carrier 12 together.

Die Vorrichtung sollte auch mehrere Stationen aufweisen, beispielsweise indem zahlreiche Träger an einer Seite eines Drehtisches parallel zueinander aufgenommen werden. Dann können nämlich zahlreiche Träger in einer Station in die entsprechenden Halterungen 34 eingesetzt, nach dem Drehen in die nächste Station mit den Borstenteilen 16 versehen werden, um dann schließlich in einer dritten Station aus der Vorrichtung ausgeworfen zu werden.The device should also have multiple stations, for example, by numerous carriers are added to one side of a turntable parallel to each other. Then, many carriers in a station can be inserted into the respective brackets 34, provided with the bristle parts 16 after turning to the next station, and finally ejected from the device at a third station.

In Figur 2 ist die fertige Bürste zu erkennen, wobei auch hier das Loch 14 zu Übersichtszwecken übergroß dargestellt ist. Gut zu erkennen ist jedoch, dass sich das Ankerteil 28 in die Lochwand 32 hineindrückt, zu der auch ein Lochboden 34 zählt.In FIG. 2 is to recognize the finished brush, whereby here too the hole 14 is shown oversized for the purpose of clarity. However, it is easy to see that pushes the anchor member 28 in the hole wall 32, to which a hole bottom 34 counts.

Die dargestellte Rundbürste ist eine sogenannte Miniaturbürste, insbesondere eine Mascara- oder Interdentalbürste, bei der der verwendete Draht einen Durchmesser von wenigen Zehntel Millimetern besitzt.The round brush shown is a so-called miniature brush, in particular a mascara or interdental brush, in which the wire used has a diameter of a few tenths of a millimeter.

Bei der Ausführungsform nach den Figuren 3 und 4 ist lediglich ein anderes Ankerteil 28 vorgesehen, sodass bezüglich Herstellungsverfahren, Vorrichtung und Bürste selbst auf die erste Ausführungsform verwiesen werden kann und bereits eingeführte Bezugszeichen für gleiche oder funktionsgleiche Teile verwendet werden.In the embodiment of the Figures 3 and 4 merely another anchor part 28 is provided, so that reference can be made to the first embodiment with respect to the manufacturing process, apparatus and brush itself and already introduced reference numerals are used for the same or functionally identical parts.

Bei dieser Ausführungsform wird ein Ankerteil 28 verwendet, das bogenförmig verläuft und seitlich sich überkreuzende, abstehende Füße 36 besitzt.In this embodiment, an anchor member 28 is used which is arcuate and laterally has crossing, protruding feet 36.

Natürlich müssen sich die Füße 36 nicht kreuzen, sie könnten auch U- oder V-förmig, das heißt parallel oder nach außen verlaufen. Die Füße 36 können auch mit Widerhaken versehen sein.Of course, the feet 36 do not have to cross, they could also be U- or V-shaped, that is parallel or outward. The feet 36 may also be barbed.

In der dargestellten Ausführungsform nach Figuren 3 und 4 wird das Ankerteil 28 durch einen zur Schlinge gebogenen Draht gebildet.In the illustrated embodiment according to Figures 3 and 4 the anchor part 28 is formed by a wire bent into a loop.

Anstatt der Verwendung eines gebogenen Drahtes kann natürlich auch ein Stanzteil oder dergleichen verwendet werden.Of course, instead of using a bent wire, a stamped part or the like may be used.

Über die Vorrichtung werden das Ankerteil 28 und das mit ihm in Zustellrichtung formschlüssig verbundene Borstenteil 16 in das Loch 14 des Trägers 12 hineingestoßen und darin verankert. Das Ankerteil 28 nimmt, da es im gebogenen trägerseitigen Ende 26 aufgenommen ist, beim Zustellen das Borstenteil 16 mit.About the device, the anchor member 28 and the form-fittingly connected in the feed bristle part 16 are pushed into the hole 14 of the carrier 12 and anchored therein. The anchor member 28 takes, since it is received in the curved carrier-side end 26, when delivering the bristle member 16 with.

Die abstehenden Füße 36 drücken oder schneiden sich in die Lochwand 32, hier zum Beispiel in den Lochboden 38, ein (siehe Figur 4), um darin bleibend verankert zu werden.The protruding feet 36 press or intersect in the hole wall 32, here for example in the hole bottom 38, a (see FIG. 4 ) in order to be permanently anchored therein.

Auch bei dieser Ausführungsform ragt das spitze, freie Ende des Abschnitts 24 nicht aus dem Loch 14 heraus. Ferner wird auch hier keine zusätzliche Sicherung des Borstenteils 16 am Träger 12 vorgesehen.Also in this embodiment, the pointed, free end of the portion 24 does not protrude out of the hole 14. Furthermore, no additional securing of the bristle part 16 on the carrier 12 is provided here as well.

Bei den gezeigten Ausführungsformen der Miniatur-Rundbürste ist nur ein einziges Borstenteil 16 am Träger 12 befestigt, und zwar über die Stirnseite.In the illustrated embodiments of the miniature round brush only a single bristle portion 16 is attached to the support 12, via the end face.

Der Träger 12 bildet gleichzeitig das Griffteil. Ein Lösen von Borstenteil 16 und Träger 12 erfolgt durch Zerstören. Bei der Einheit von Träger 12 und Borstenteil 16 handelt es sich folglich um ein Einweg-Teil.The carrier 12 simultaneously forms the handle part. A release of bristle portion 16 and support 12 is done by destroying. The unit of carrier 12 and bristle portion 16 is thus a disposable part.

Die Ausführungsformen nach den Figuren 5 und 6 zeigen den Träger 12, der unterschiedliche Formen aufweist, nämlich einerseits (Figur 5) ein kreiszylindrisches Ende mit einem kreiszylindrischen Loch 14 und andererseits (Figur 6) ein im Querschnitt ovales Ende mit einem länglichen, hier insbesondere einem ovalen Loch 14. Mit dem Bezugszeichen 32 ist die Lochwand bezeichnet, zu der auch jeweils der Lochboden 38 zu zählen ist. Auch hier schneidet sich das Trägerteil 28 entweder in den zylindrischen Abschnitt der Lochwand 32 und/oder in den Lochboden 38 ein.The embodiments according to the FIGS. 5 and 6 show the carrier 12, which has different shapes, namely on the one hand ( FIG. 5 ) a circular cylindrical end with a circular cylindrical hole 14 and on the other hand ( FIG. 6 ) An oval in cross-section end with an elongated, in particular an oval hole 14. The reference numeral 32 denotes the hole wall, to which also the hole bottom 38 is to count. Again, the support member 28 cuts either in the cylindrical portion of the hole wall 32 and / or in the hole bottom 38 a.

Die Figuren 7 und 8 zeigen die Bürste mit einem Träger nach Figur 6. Man erkennt an diesen Ausführungsformen, dass durch die längliche Form des Loches 14 genügend Platz für die Unterbringung des U-förmig gebogenen Borstenteils 16 ist. Bei dieser Ausführungsform ist das Borstenteil auf der gesamten Längserstreckung mit Borsten 20 versehen, sodass auch im Loch 14 Borsten 20 liegen. In Figur 8 ist ferner zu erkennen, dass das Ankerteil 28 sich in den Lochboden 38 hineinschneidet.The FIGS. 7 and 8 show the brush with a carrier FIG. 6 , It can be seen from these embodiments that due to the elongated shape of the hole 14 there is sufficient space for housing the U-shaped bristle part 16. In this embodiment, the bristle part is provided with bristles 20 over the entire longitudinal extent, so that bristles 20 are also located in the hole 14. In FIG. 8 It can also be seen that the anchor part 28 cuts into the hole bottom 38.

Die Ausführungsform nach den Figuren 9 und 10 zeigt eine besondere und neuartige Ausgestaltung, da zu den radial verlaufenden Borsten 20 auch noch axial zum trägerseitigen Ende des verdrillten Drahtabschnitts parallel verlaufende zusätzliche Borsten 40 vorgesehen sind. Diese Borsten 40 werden zusammen mit den Borsten 20 gestanzt und können natürlich nachbearbeitet werden (geschnitten, verrundet). Auch vorbearbeitete Borsten mit vorverrundeten, zugespitzten oder geschlitzten Enden etc. sind natürlich verarbeitbar. Die Borsten 40 werden zusammen mit dem verdrillten Draht um 180° umgebogen und über das Trägerteil 28 (im Beispiel die Schlinge) gefasst und im Loch 14 gehalten.The embodiment according to the FIGS. 9 and 10 shows a special and novel design, since the radially extending bristles 20 and axially parallel to the carrier-side end of the twisted wire section parallel extending additional bristles 40 are provided. These bristles 40 are punched together with the bristles 20 and can of course be reworked (cut, rounded). Also pre-machined bristles with pre-rounded, pointed or slotted ends etc. are of course processable. The bristles 40 are bent together with the twisted wire by 180 ° and taken over the support member 28 (in the example, the loop) and held in the hole 14.

Alternativ können die zusätzlichen Borsten 40 natürlich auch über ein Ankerplättchen im Loch befestigt werden, indem sie um das Ankerplättchen herumgebogen sind.Alternatively, the additional bristles 40 may of course also be secured in the hole via an anchor plate by being bent around the anchor plate.

Die zusätzlichen Borsten 40 erstrecken sich vorzugsweise nicht ganz bis zu den radial verlaufenden Borsten 20 und sind sozusagen endseitig von diesen beabstandet. Die zusätzlichen Borsten 40 dienen dazu, den Übergang zwischen der Zahnoberfläche und dem Zahnfleisch zu reinigen.The additional bristles 40 preferably do not extend all the way to the radially extending bristles 20 and are so to speak spaced therefrom at the ends. The additional bristles 40 serve to clean the transition between the tooth surface and the gum.

Alternativ zu den gezeigten Rundbürsten könnten natürlich auch Bürsten hergestellt werden, die nicht kreiszylindrisch sind, sondern konische Bürstenformen ergeben oder spiralförmig oder auch Bürsten, bei denen der Draht nicht den Mittelpunkt des Bürstenquerschnitts bildet. Es müssen auch nicht gleichmäßig am Umfang verteilte Borsten 20 vorgesehen sein, hier ließen sich auch Borsten zu einer Spirale oder dergleichen zusammenfassen.As an alternative to the round brushes shown, brushes could naturally also be produced which are not circular-cylindrical but result in conical brush shapes or spirally or else brushes in which the wire does not form the center of the brush cross-section. It must also not uniformly distributed around the circumference bristles 20 may be provided here could be bristles to form a spiral or the like summarized.
