Elektrisch angetriebene ZahnbürsteElectric toothbrush
Die Erfindung betrifft eine elektrisch angetriebene Zahnbürste mit einem Antriebsmotor und Getriebemitteln sowie mit einem ersten oszillierend um eine Rotationsachse hin- und herschwingend angetriebenen Borstenträger und einem zweiten Borstenträger, der jeweils entgegengesetzt zum ersten Borstenträger oszillierend um eine Rotationsachse hin- und herschwingend antreibbar ist.The invention relates to an electrically driven toothbrush with a drive motor and gear means as well as with a first bristle carrier driven to swing back and forth about a rotation axis and a second bristle carrier which can be driven to swing back and forth about a rotation axis in an oscillating manner opposite to the first bristle carrier.
Eine derartige Zahnbürste ist beispielsweise in der US-PS 5 070 587 beschrieben. Diese Zahnbürste umfaßt mehrere in Reihen oder entlang von Kreislinien nebeneinander angeordnete Borstenträger, die jeweils oszillierend um ihre eigenen Rotationsachsen hin- und herschwingend antreibbar sind. Diese Konstruktion benötigt eine Vielzahl von Antriebsübertragungselementen, insbesondere in Form von Zahnritzeln und ist daher relativ aufwendig in der Herstellung und in ihrer Montage.Such a toothbrush is described, for example, in US Pat. No. 5,070,587. This toothbrush comprises several bristle carriers arranged next to one another in rows or along circular lines, each of which can be driven to swing back and forth around its own axis of rotation. This design requires a large number of drive transmission elements, particularly in the form of pinions, and is therefore relatively complex to manufacture and assemble.
In der DE-28 47 631 Al ist eine elektrisch angetriebene Zahnbürste beschrieben, die einen kreisscheibenförmigen, mit Borsten besetzten Borstenträger umfaßt, der um seine Rotationsachse hin- und hergehend oszillierend antreibbar ist.DE-28 47 631 A1 describes an electrically driven toothbrush which comprises a circular disk-shaped bristle carrier fitted with bristles which can be driven in an oscillating manner back and forth about its axis of rotation.
Der Erfindung liegt die Aufgabe zugrunde, eine in ihrer Konstruktion und Funktionsweise einfache elektrisch angetriebene Zahnbürste zu schaffen.The invention is based on the object of creating an electrically powered toothbrush that is simple in its construction and functioning.
Zur Lösung dieser Aufgabe ist die erfindungsgemäße Zahnbürste dadurch gekennzeichnet, daß beide Borstenträger eine gemeinsame Rotationsachse haben.To achieve this object, the toothbrush according to the invention is characterized in that both bristle carriers have a common axis of rotation.
Weitere Merkmale der Erfindung ergeben sich aus den Unteransprüchen.Further features of the invention emerge from the subclaims.
Die Erfindung wird im folgenden anhand der Zeichnung näher beschrieben.The invention is described in more detail below with reference to the drawing.
Figur 1 zeigt in schematischer Darstellung eine Gesamtansicht der erfindungsgemäßen Zahnbürste;Figure 1 shows a schematic representation of an overall view of the toothbrush according to the invention;
Figur 2 zeigt in schematischer Darstellung eine erste Ausführungsform des Antriebsmechanismus der erfindungsgemäßen Zahnbürste;Figure 2 shows a schematic representation of a first embodiment of the drive mechanism of the toothbrush according to the invention;
Figur 3 zeigt in schematischer Darstellung eine zweite Ausführungsform der erfindungsgemäßen Zahnbürste.Figure 3 shows a schematic representation of a second embodiment of the toothbrush according to the invention.
Gemäß Figur 1 ist am vorderen Ende eines Zahnbürstengehäuses A ein zwei Borstenträger umfassender Borstenträgersatz 1.2 angeordnet, dessen Borstenträger um die Achse X-X oszillierend hin- und herschwingend antreibbar sind.According to Figure 1, a bristle carrier set 1.2 comprising two bristle carriers is arranged at the front end of a toothbrush housing A, the bristle carriers of which can be driven to swing back and forth in an oscillating manner about the axis X-X.
In dem Gehäuse A ist gemäß den Figuren 2 und 3 ein batterie- oder netzgespeister Antriebsmotor 3 untergebracht, der über eine Pleuelstange 3.1 ein Schubelement 4 in Richtung des Doppelpfeiles fl antreibt.According to Figures 2 and 3, a battery- or mains-powered drive motor 3 is housed in the housing A, which drives a thrust element 4 in the direction of the double arrow fl via a connecting rod 3.1.
Der Borstentragersatz 1, 2 umfaßt einen ersten inneren kreisförmigen Borstenträger 1 und einen zweiten äußeren kreisringförmigen Borstenträger 2, der den ersten Borstenträger 1 umgibt. Die beiden Borstenträger können mit jeweils unterschiedlich langen Borsten 1.1 bzw. 2.1 besetzt sein.The bristle carrier set 1, 2 comprises a first inner circular bristle carrier 1 and a second outer circular bristle carrier 2, which surrounds the first bristle carrier 1. The two bristle carriers can each be equipped with bristles 1.1 and 2.1 of different lengths.
Gemäß Figur 2 treibt das Schubelement 4 zwei stangenförmige Antriebsmittel in Form von Pleuelstangen 4.1 bzw. 4.2 an. Die Pleuelstange 4.1 greift exzentrisch zur Rotationsachse X-X an einem Schwenkhebel 1.2 an, der an dem inneren Borstenträger 1 befestigt ist. Die zweite Pleuelstange 4.2 ist an dem zweiten Borstenträger 2 angelenkt, und zwar, bezogen auf die gemeinsame Rotationsachse X-X, im wesentlichen gegenüberliegend zu dem Anlenkpunkt der Pleuelstange 4.1 an dem Hebel 1.2. Auf diese Weise ist gewährleistet, daß bei hin- und herschwingendem Schubelement 4 über die beiden Pleuelstangen 4.1 und 4.2 die beiden Borstenträger 1 bzw. jeweils gegenläufig angetrieben werden.According to Figure 2, the thrust element 4 drives two rod-shaped drive means in the form of connecting rods 4.1 and 4.2. The connecting rod 4.1 engages eccentrically to the rotation axis X-X on a pivot lever 1.2, which is attached to the inner bristle carrier 1. The second connecting rod 4.2 is hinged to the second bristle carrier 2, namely, in relation to the common rotation axis X-X, essentially opposite to the hinge point of the connecting rod 4.1 on the lever 1.2. In this way, it is ensured that when the thrust element 4 swings back and forth, the two bristle carriers 1 and 2 are each driven in opposite directions via the two connecting rods 4.1 and 4.2.
Bei der Ausführungsform gemäß Figur 5 sind an dem gemeinsamen Schubelement 5 stangenförmige Antriebselemente in Form von Zahnstangen 5.1 bzw. 5.2 angebracht. Die erste Zahnstange 5.1 kämmt mit einem an dem inneren Borstenträger 1 angebrachten Ritzel 6, während die zweite Zahnstange 5.2 mit einem am äußeren Borstenträger 2 vorgesehenen Ritzel 2.2 kämmt. In diesem FallIn the embodiment according to Figure 5, rod-shaped drive elements in the form of racks 5.1 and 5.2 are attached to the common pusher element 5. The first rack 5.1 meshes with a pinion 6 attached to the inner bristle carrier 1, while the second rack 5.2 meshes with a pinion 2.2 provided on the outer bristle carrier 2. In this case
greifen die beiden Zahnstangen 5.1 bzw. 5.2 an den beiden Borstenträgern - bezogen auf deren gemeinsame Rotationsachse - an sich diametral gegenüberliegenden Seiten an.The two racks 5.1 and 5.2 engage the two bristle carriers on diametrically opposite sides relative to their common axis of rotation.
