Description

Die Erfindung betrifft eine Zahnbürste mit einer auswechselbaren Borstenplatte nach dem Oberbegriff des Anspruchs 1.The invention relates to a toothbrush with an exchangeable bristle plate according to the preamble of claim 1.

Zahnbürsten mit einem wechselbaren Borstenabschnitt werden dem wachsenden Hygiene- und Umweltbewußtsein gerecht. Jährlich werden ungeheure Mengen an Zahnbürsten verbraucht, und zwar mit steigender Tendenz, wobei der Verbraucher alle 2 bis 3 Monate die Zahnbürste wechseln soll. Das ist hygienisch notwendig. Nicht notwendig ist dagegen, die Zahnbürste komplett wegzuwerfen.Toothbrushes with an exchangeable bristle section are growing Hygiene and environmental awareness. Every year there are enormous amounts of Toothbrushes are consumed, and with an increasing tendency, the Consumers should change their toothbrush every 2 to 3 months. It is hygienic necessary. However, it is not necessary to throw the toothbrush away completely.

Abhilfe schaffen hier die sogenannten Wechselkopf-Zahnbürsten, die unter Beibehaltung des Bürstengriffs nur den Borstenkopf ersetzen. Eine derartige Zahnbürste ist bekannt aus G 85 25 867.9, bei der ein Griffteil mit einem Bürstenteil vorgegebener Länge lösbar verbunden ist, damit der gesamte Borstenbereich vollflächig durch ein Verbinderbereich des Griffteils unterstützt ist. Für eine Preßpassung mit nur einer Nut-Federverbindung in Form eines Stiftansatzes ist vorgesehen, daß ein Ansatz am Griffteil hinterschnitten und winkelförmig ausgeführt ist, so daß das Borstenteil mit einem entsprechend passend geformten Ende gegen seitliche Verschiebung und Abheben formschlüssig gesichert gehalten wird. Zum Lösen der Verbindung ist endseitig eine schlitzförmige Ausnehmung eingebracht, in die ein Werkzeug eingeführt werden kann.This is remedied by the so-called interchangeable toothbrushes below Retaining the brush handle only replace the bristle head. Such Toothbrush is known from G 85 25 867.9, in which a handle part with a Brush part of predetermined length is releasably connected, so the entire Bristle area is fully supported by a connector area of the handle part. For a press fit with only one tongue and groove connection in the form of a Pin approach is provided that an undercut on the handle part and is angular, so that the bristle part with a corresponding suitably shaped end against lateral displacement and lifting is positively secured. To end the connection is at the end introduced a slot-shaped recess into which a tool is inserted can be.

Als nachteilig erwiesen hat sich jedoch, daß die Konstruktion zur sicheren Befestigung des Borstenabschnitts zu aufwendig ist, so daß zum Lösen der Verbindung zusätzliche Werkzeuge erforderlich sind oder eingenständige Konstruktionselemente zum Lösen der Verbindung vorgesehen sein müssen.It has proven to be disadvantageous, however, that the construction is safe Attachment of the bristle section is too expensive, so that to solve the Connection additional tools are required or stand alone Construction elements for releasing the connection must be provided.

Aus der DE 44 34 617 A1 ist eine Zahnbürste mit einem auswechselbaren Borsteneinsatz bekannt, der in einer länglichen Halteaussparung eines Kopfteils einrastbar aufgenommen ist. Rastleisten an der Umfangsfläche des Borsteneinsatzes greifen in Rastnuten des Kopfteils. Der Borsteneinsatz verjüngt sich im Grundriß von seinem einen Ende zu seinem anderen Ende und liegt mit glatten, ununterbrochenen Abschnitten seiner Umfangsfläche flächig an glatten, ununterbrochenen Abschnitten der Innenwand an, so daß sich eine Keil- oder Klemmwirkung des Borsteneinsatzes in Längsrichtung ergibt. Bei dieser vorbekannten Zahnbürste wird beim Auswechseln die Borstenplatte durch Druck auf einen Drückerknopf aus der Rastverbindung gedrückt. Das Lösen einer solchen Rastverbindung ist im allgemeinen schwergängig und daher nachteilig in der Handhabung.DE 44 34 617 A1 describes a toothbrush with a replaceable one Bristle insert known in an elongated holding recess of a head part is snapped into place. Snap bars on the peripheral surface of the Bristle insert engage in locking grooves in the head part. The bristle insert tapers in the floor plan from one end to the other end and lies with smooth, uninterrupted sections of its circumferential surface flat on smooth, uninterrupted sections of the inner wall, so that there is a wedge or Longitudinal clamping effect of the bristle insert results. At this Known toothbrush is when replacing the bristle plate by pressure pressed on a push button out of the locking connection. Solving one such latching connection is generally sluggish and therefore disadvantageous in handling.

Aufgabe der Erfindung ist es daher, eine Zahnbürste mit einer auswechselbaren Borstenplatte zu schaffen, die einerseits eine sichere Befestigung der Borstenplatte an einem Zahnbürstenkörper und andererseits ein einfaches Wechseln der Borstenplatte erlaubt.The object of the invention is therefore a toothbrush with a replaceable Bristle plate to create a secure attachment of the one hand Bristle plate on a toothbrush body and on the other hand a simple one Exchange of the bristle plate allowed.

Diese Aufgabe wird durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst.This task is characterized by the characteristics of the characteristic part of the Claim 1 solved.

Hierdurch wird eine Zahnbürste mit einer auswechselbaren Borstenplatte geschaffen, die eine versatzsichere Verankerung der Borstenplatte auf der Trägerplatte einer ansonsten unveränderten Zahnbürste erlaubt und dabei sehr einfach zu handhaben und zu lösen ist. Es wird nur ein geringfügiger Anteil des Gesamtmaterials der Zahnbürste gewechselt. Die rundkeilförmige Hinterschneidung, in die der Rundkeil der Borstenplatte schließend eingreift, macht jeglichen Versatz nach oben unmöglich. Es ist auch nicht möglich, durch Druck auf die zentrale Verriegelung die Borstenplatte nach oben auszustoßen. In Verbindung mit der längsgeformten Zentralverriegelung wird jegliche seitliche Verschiebbarkeit unterbunden, so daß die Borstenplatte unverrückbar fest verankert ist. Entscheidend ist allerdings, daß diese feste Verankerung einfach lösbar ist durch ein Biegen, wodurch sich die Hinterschneidung öffnet.This will make a toothbrush with a replaceable bristle plate created an offset-safe anchoring of the bristle plate on the Carrier plate of an otherwise unchanged toothbrush allowed and very much is easy to use and to solve. It will only be a minor part of the All toothbrush material changed. The round wedge-shaped undercut, in which the round wedge of the bristle plate engages makes any offset upwards impossible. It is also not possible to press on the central locking mechanism expels the bristle plate upwards. In Connection with the longitudinally shaped central locking system is any side Slidability prevented, so that the bristle plate is immovable is anchored. It is crucial, however, that this firm anchoring is simple can be released by bending, which opens the undercut.

Als vorteilhaft hat sich insoweit erwiesen, wenn die Hinterschneidung von innen nach außen hin sich jeweils verkleinert, um beim Biegen das Lösen des Eingriffs des formangepaßten Endes der Borstenplatte zu begünstigen.It has proven to be advantageous if the undercut from the inside towards the outside it shrinks to loosen the engagement when bending favor the shape-matched end of the bristle plate.

Als Material für den Zahnbürstenkörper wird vorzugsweise Kunststoff, wie Polypropylen (PP), Polyethylenterephthalat (PET) oder Polyethylenterephthalat für Spritzguß geeignet (PETG); verwendet. Dieses Material ist hinreichend flexibel, was für die Wechselfunktion und für den Gebrauch der Zahnbürste vorteilhaft ist.Plastic, such as, is preferably used as the material for the toothbrush body Polypropylene (PP), polyethylene terephthalate (PET) or polyethylene terephthalate for Suitable for injection molding (PETG); used. This material is sufficiently flexible which is advantageous for the changing function and for the use of the toothbrush.

    • Die Fig. 1 und 2 zeigen ein kopfseitiges Teilstück einer Zahnbürste mit einem Zahnbürstenhals 1 eines Zahnbürstenkörpers, an den sich kopfseitig eine Trägerplatte 2 anschließt. Vorzugsweise ist die Trägerplatte 2 einstückig mit dem Zahnbürstenhals 1 verbunden.1 and 2 show a head-side section of a toothbrush with a Toothbrush neck 1 of a toothbrush body, on the head side of which is a carrier plate 2 connects. The carrier plate 2 is preferably in one piece with the toothbrush neck 1 connected.

    Die Trägerplatte 2 besitzt die äußeren Konturen eines Zahnbürstenkopfes wählbarer Abmessungen. In der Trägerplatte 2 ist eine längsgeformte Öffnung ausgebildet, die eine Nut 3 für eine Nut-Verbindung mit einer auswechselbaren Borstenplatte 6 bildet Die Nut 3 ist zentral angeordnet, d.h. entlang einer Mittelline der Trägerplatte 2.The carrier plate 2 has the outer contours of a toothbrush head selectable Dimensions. An elongated opening is formed in the carrier plate 2, the one groove 3 for a groove connection with an interchangeable Bristle plate 6 forms the groove 3 is arranged centrally, i.e. along a center line the carrier plate 2.

    Zahnbürstenhalsseitig wird die Trägerplatte 2 begrenzt von einem hinterschnittenen Anschlag 4 des Zahnbürstenkörpers. Diese Hinterschneidung des Anschlages 4 ist rundkeilförmig ausgeführt, wobei die Hinterschneidung von innen nach außen zur randseitigen Begrenzung der Trägerplatte 2 hin sich verkleinert.On the toothbrush neck side, the carrier plate 2 is delimited by an undercut Stop 4 of the toothbrush body. This undercut of the Stop 4 is designed like a round wedge, the undercut from the inside outwards towards the edge of the carrier plate 2 is reduced.

    Auf die Trägerplatte 2 ist eine in den Fig. 3 bis 5 dargestellte Borstenplatte 6 aufschnappbar. Die Borstenplatte 6 besitzt Abmessungen, die an die Abmessungen der Trägerplatte 2 angepaßt sind, damit die Borstenplatte vollständig von der Trägerplatte 2 abgestützt wird. Hierdurch werden auch Kanten vermieden, die beim Zähneputzen störend sein könnten. Die Borstenplatte 6 weist an ihrer Unterseite eine vorspringende längsförmige Feder 5 auf (vgl. Fig. 5), die formschlüssig in die Nut 3 der Trägerplatte einsetzbar ist. Ferner besitzt die Borstenplatte 6 an einer dem Zahnbürstenhals 1 zugewandten Seite ein Ende, das als Rundkeil 7 ausgebildet ist. Der Rundkeil ist formangepaßt an die rundkeilige Hinterschneidung des Anschlages 4 für eine formschlüssige Preßpassung von Borstenplatte 6 und Anschlag 4 bei einer Verankerung von Borstenplatte 6 und Trägerplatte 2 über die Nut-Feder-Verbindung 3, 5.A bristle plate 6 shown in FIGS. 3 to 5 is on the carrier plate 2 snappable. The bristle plate 6 has dimensions that match the dimensions the support plate 2 are adapted so that the bristle plate completely from the support plate 2 is supported. This also avoids edges that when brushing your teeth could be annoying. The bristle plate 6 has on it Underside of a projecting longitudinal spring 5 (see. Fig. 5), the form-fitting can be inserted into the groove 3 of the carrier plate. The bristle plate also has 6 on one side facing the toothbrush neck 1 has one end, which as Round wedge 7 is formed. The round wedge is matched to the round wedge Undercut of the stop 4 for a positive interference fit Bristle plate 6 and stop 4 when anchoring bristle plate 6 and Carrier plate 2 via the tongue and groove connection 3, 5.

    Die Borstenplatte 6 ist somit mit ihrer Unterseite flächig auf die Trägerplatte 2 aufsetzbar. Von der der Unterseite gegenüberliegenden Oberseite der Borstenplatte 6 erstreckt sich ein Feld von Borsten 8, die in der Borstenplatte 6 verankert sind und damit von dieser getragen werden.The underside of the bristle plate 6 is thus flat on the carrier plate 2 attachable. From the top of the bristle plate opposite the underside 6 extends a field of bristles 8, which is anchored in the bristle plate 6 and are therefore borne by it.

    Der Zahnbürstenkörper besteht mindestens im Bereich der Trägerplatte 2 und des Zahnbürstenhalses 1 aus einem flexiblen Material. Besonders bevorzugt ist Polypropylen (PP), Polyethylenterephthalat (PET), oder Polyethylenterephthalat für Spritzguß geeignet (PETG). Die Borstenplatte 6 selbst kann von einer dünnen Plastikplatte gebildet werden.The toothbrush body consists at least in the area of the carrier plate 2 and Toothbrush neck 1 made of a flexible material. Is particularly preferred Polypropylene (PP), polyethylene terephthalate (PET), or polyethylene terephthalate suitable for injection molding (PETG). The bristle plate 6 itself can be thin Plastic plate are formed.

    Das Aufbringen und Lösen der Borstenplatte 6 geschieht denkbar einfach wie folgt:The application and detachment of the bristle plate 6 is very simple follows:

    Der Rundkeil 7 wird schräg von oben in das Gegenstück, d. h. die Hinterschneidung des Anschlags 4, eingesetzt und die Borstenplatte 6 fest niedergedrückt, so daß die Zentralverriegelung 3, 5 einschnappt. Jetzt ist die Borstenplatte 6 unverrückbar fest verankert.The circular wedge 7 is slanted from above into the counterpart, d. H. the undercut of the stop 4, inserted and the bristle plate 6 firmly depressed, so that the central locking 3, 5 snaps. Now the bristle plate 6 firmly anchored.

    Zum Lösen wird der Zahnbürstenhals 1 mit der Trägerplatte 2 etwas konvex gebogen, wodurch die Keilhalterung 4, 7 ausgehebelt und die Borstenplatte 6 frei gegeben wird. Zum Biegen können die Finger der einen Hand zur Unterstützung etwa in Höhe des Zahnbürstenhalses 1 unter die Zahnbürste gehalten und mit dem Daumen der anderen Hand die Spitze der Borstenplatte 6 nach unten gedrückt werden.To release the toothbrush neck 1 with the carrier plate 2 is somewhat convex bent, which levered the wedge holder 4, 7 and the bristle plate 6 free is given. The fingers of one hand can be used to support bending about the level of the toothbrush neck 1 held under the toothbrush and with the tip of the bristle plate 6 with the thumb of the other hand be pressed.
