Elektrische ZahnbürsteElectric toothbrush
Die Erfindung betrifft eine elektrische Zahnbürste mit einer von einem Elektromotor über ein Getriebe angetrie¬ benen Zahnburstenachse, wobei das Getriebe über eine quer zur Zahnburstenachse verlaufenden Achse in einem Halter gehäusefest gehalten ist.The invention relates to an electric toothbrush with a toothbrush axis driven by an electric motor via a gear, the gear being held in a holder fixed to the housing via an axis extending transversely to the toothbrush axis.
Bei elektrischen Zahnbürsten der vorstehenden Art tritt das Problem auf, daß es zu einer Beschädigung oder gar Zerstörung ihres Getriebes kommen kann, wenn die Zahnbür¬ ste versehentlich fallengelassen wird und dabei unglück¬ licherweise mit der Stirnseite ihrer Zahnburstenachse auf den Boden trifft. Die dann axial in die Zahnburstenachse gelangende Stoßkraft ist meist so groß, daß das Getriebe zerstört wird.In the case of electric toothbrushes of the above type, the problem arises that damage or even destruction of their gear can occur if the toothbrush is accidentally dropped and, unfortunately, hits the floor with the end face of its toothbrush axis. The impact force then axially into the toothbrush axis is usually so great that the gearbox is destroyed.
Der Erfindung liegt das Problem zugrunde, eine elektri¬ sche Zahnbürste der eingangs genannten Art mit möglichst geringem Aufwand so auszubilden, daß sie auch einen un¬ glücklichen Sturz, bei dem sie mit der Zahnburstenachse auftrifft, ohne Schaden zu überstehen vermag.The invention is based on the problem of designing an electric toothbrush of the type mentioned at the beginning with as little effort as possible so that it can withstand an unfortunate fall in which it hits the toothbrush axis without damage.
Dieses Problem wird erfindungsgemäß dadurch gelöst, daß die Achse an gegenüberliegenden Seiten jeweils in Längs¬ richtung der Zahnburstenachse federnd gelagert ist.This problem is solved according to the invention in that the axis is resiliently mounted on opposite sides in the longitudinal direction of the toothbrush axis.
Bei einer solchen Zahnbürste kann sich die Zahnbursten¬ achse zusammen mit dem Getriebe relativ zu ihrem Elektro¬ motor elastisch verschieben, wenn eine Schlagkraft auf ihre Zahnburstenachse wirkt. Dadurch wird der Schlag ela¬ stisch abgefangen, so daß es nicht zu einer Beschädigung des Getriebes oder anderer Bauteile der Zahnbürste kommt.
Die federnde Lagerung der Achse der Zahnbürste kann auf unterschiedliche Weise erfolgen. Eine sehr einfache Aus¬ führungsform besteht darin, daß die Achse durch eine Dämpfungsbuchse in dem Halter gelagert ist.In such a toothbrush, the toothbrush axis can move elastically together with the gearbox relative to its electric motor when an impact force acts on its toothbrush axis. As a result, the impact is intercepted elastically so that the gearbox or other components of the toothbrush are not damaged. The resilient mounting of the toothbrush axis can be done in different ways. A very simple embodiment consists in that the axle is supported in the holder by a damping bush.
Alternativ ist es jedoch auch möglich, wenn die Achse in einem rohrschellenartigen Federteil in dem Halter gela¬ gert ist.Alternatively, however, it is also possible for the axle to be mounted in the holder in a tube-like spring part.
Die erfindungsgemäße federnde Lagerung der Achse des Ge¬ triebes kann bei unterschiedlich gestalteten Getrieben erfolgen. Besonders vorteilhaft ist sie jedoch bei einer elektrischen Zahnbürste anwendbar, dessen Zahnbursten¬ achse von einer umlaufenden Motorwelle in eine Pendelbe¬ wegung um ihre Längsachse und eine hin- und hergehende Bewegung in Richtung ihrer Längsachse versetzbar ist, wo¬ bei zur Erzeugung der Pendelbewegung auf der Zahnbursten¬ achse eine radial zu ihr ausgerichtete und fest mit ihr verbundene Schwinge vorgesehen ist und wobei die Zahnbür¬ ste zur Erzeugung der hin- und hergehenden Bewegung der Zahnburstenachse einen von dem Elektromotor angetriebenen Exzenter hat, der in einen mit der Zahnburstenachse ver¬ bundenen Mitnehmer eingreift, und die sich dadurch aus¬ zeichnet, daß der Mitnehmer eine quer zur Zahn¬ burstenachse verlaufende Bohrung hat, in die der Exzenter zur Erzeugung einer kreisförmigen Bewegung des Mitnehmers eingreift, daß der Mitnehmer desweiteren eine quer zur Zahnburstenachse verlaufende Nut hat, mit der er quer zur Zahnburstenachse verschiebbar über einen fest mit der Zahnburstenachse verbundene, als Nutenstein ausgebildete und radial zur Zahnburstenachse ausgerichtete Schwinge greift, daß die Schwinge um die Längsachse der Zahn¬ burstenachse begrenzt kippbar in der Nut gehalten ist und daß zur Erzeugung der Pendelbewegung der Schwinge und da-
mit der Zahnburstenachse die Schwinge mit dem Mitnehmer durch eine Schwenkverbindung gekuppelt ist.The resilient mounting of the axis of the transmission according to the invention can take place with differently designed transmissions. However, it is particularly advantageously applicable to an electric toothbrush whose toothbrush axis can be set in a pendulum motion about its longitudinal axis and a reciprocating motion in the direction of its longitudinal axis by a rotating motor shaft, whereby to generate the pendulum motion on the Toothbrush axis a radially aligned and firmly connected rocker is provided and the toothbrush for generating the reciprocating movement of the toothbrush axis has an eccentric driven by the electric motor, which in a driver connected to the toothbrush axis engages, and which is characterized in that the driver has a bore extending transversely to the toothbrush axis, into which the eccentric engages to produce a circular movement of the driver, that the driver furthermore has a groove running transversely to the toothbrush axis, with which it can be moved across the toothbrush axis via e A rocker, which is firmly connected to the toothbrush axis and is designed as a sliding block and is oriented radially to the toothbrush axis, engages in that the rocker is held in the groove such that it can be tilted to a limited extent about the longitudinal axis of the toothbrush axis, and in with the toothbrush axis the rocker is coupled to the driver by a swivel connection.
Bei einer solchen Zahnbürste genügt ein einziger, vom Elektromotor der Zahnbürste angetriebener Exzenter, um beide Bewegungen der Zahnburstenachse zu erzeugen. Des¬ halb kann man die Achse dieses einzigen Exzenters auf einfache Weise gemäß der Erfindung federnd gelagert wer¬ den, um Stöße abzufangen.With such a toothbrush, a single eccentric, driven by the electric motor of the toothbrush, is sufficient to generate both movements of the toothbrush axis. Therefore, the axis of this single eccentric can easily be resiliently mounted according to the invention in order to absorb shocks.
Die Erfindung läßt zahlreiche Ausführungsformen zu. Zur weiteren Verdeutlichung ihres Grundprinzips wird nachfol¬ gend auf die Zeichnung Bezug genommen. Diese zeigt inThe invention permits numerous embodiments. To further clarify its basic principle, reference is made below to the drawing. This shows in

Fig.3 eine perspektivische Darstellung eines Federteils zur Lagerung der Achse,3 shows a perspective view of a spring part for mounting the axle,
Fig.4 eine Seitenansicht des Federteils mit der Zahnburstenachse und einem Halter.4 shows a side view of the spring part with the toothbrush axis and a holder.
Die Figur 1 zeigt von einer elektrischen Zahnbürste einen gehäusefest in ihr anzuordnenden Halter 1, in welchem eine Zahnburstenachse 2 derart gelagert ist, daß sie in Längsrichtung eine hin- und hergehende Bewegung und zu¬ sätzlich um ihre Längsachse 3 eine pendelnde Bewegung auszuführen vermag. Auf das freie, in Figur 1 gesehen linke Ende der Zahnburstenachse 2 ist eine nicht ge¬ zeigte, jedoch übliche Aufsteckbürste aufzustecken.
Zum Antrieb der Zahnburstenachse 2 dient ein Elektromotor 4, welcher mittels einer nicht zu erkennenden Motorwelle ein Ritzel 5 antreibt, das mit der Verzahnung eines ge¬ häusefest gelagerten Kronenrads 6 kämmt. Dieses Kronenrad 6 hat einen sich quer zur Zahnburstenachse 2 erstrecken¬ den Exzenter 7, welcher durch eine Bohrung eines Mitneh¬ mers 9 hindurchführt. Der Mitnehmer 9 bewegt sich deshalb bei laufendem Elektromotor 4 kreisförmig in einer par¬ allel zur Ebene des Kronenrades 6 verlaufenden Ebene. Das Kronenrad 6 bildet mit dem Mitnehmer 9 und weiteren, in Figur 1 nicht zu sehenden Bauteilen ein Getriebe 24.FIG. 1 shows an electric toothbrush with a holder 1 which is fixed to the housing and in which a toothbrush axis 2 is mounted such that it can perform a reciprocating movement in the longitudinal direction and, in addition, can perform an oscillating movement about its longitudinal axis 3. On the free left end of the toothbrush axis 2 as seen in FIG. An electric motor 4 is used to drive the toothbrush axis 2, which drives a pinion 5 by means of a motor shaft which cannot be recognized and which meshes with the toothing of a crown wheel 6 mounted fixed to the housing. This crown wheel 6 has an eccentric 7 which extends transversely to the toothbrush axis 2 and which passes through a bore in a driver 9. The driver 9 therefore moves in a circular manner in a plane running parallel to the plane of the crown gear 6 when the electric motor 4 is running. The crown gear 6 forms a gear 24 with the driver 9 and other components that cannot be seen in FIG. 1.
Wichtig für die Erfindung ist, daß der Exzenter 7 mit ei¬ ner Achse 17 unter Zwischenschaltung jeweils einer Dämp¬ fungsbuchse 22, 23 an seinen gegenüberliegenden Enden in dem Halter 1 gelagert ist.It is important for the invention that the eccentric 7 with its axis 17 is mounted in the holder 1 at its opposite ends with the interposition of a damping bushing 22, 23 in each case.
Die Figur 2 verdeutlicht, daß der Mitnehmer 9 in seiner der Zahnburstenachse 2 zugewandten Stirnfläche 10 eine als T-Nut ausgebildete, quer zur Zahnburstenachse 2 ver¬ laufende Nut 11 hat, welche über eine als Nutenstein aus¬ gebildete Schwinge 12 greift, die ihrerseits in der Nut 11 um die Längsachse 3 der Zahnburstenachse 2 kippbar eingreift.FIG. 2 illustrates that the driver 9 has in its end face 10 facing the toothbrush axis 2 a groove 11 which is designed as a T-groove and runs transversely to the toothbrush axis 2 and which engages over a rocker arm 12 which is designed as a sliding block and which in turn engages in the groove 11 engages tiltably about the longitudinal axis 3 of the toothbrush axis 2.
Die Zahnburstenachse 2 hat desweiteren einen radial aus¬ gerichteten Nocken 13, welcher durch eine Schwenkverbin¬ dung 14 mit dem Mitnehmer 9 derart verbunden ist, daß sie zusammen mit der Zahnburstenachse 2 um die Längsachse 3 pendeln kann, was dem Mitnehmer 9 nicht möglich ist, weil er vom Exzenter 7 gehalten wird. Die Schwenkverbindung 14 ist bei diesem Ausführungsbeispiel durch eine Ausnehmung 15 in der Stirnfläche 10 des Mitnehmers 9 gebildet, in die der Nocken 13 eingreift und die sich jeweils von ei¬ ner Kippkante 16, welche gegen jeweils eine Seite des
Nockens 13 anliegt, nach oben und unten in ihrer Breite erweitert. Bewegt sich in Figur 2 gesehen der Mitnehmer 9 durch die Bewegung des Exzenters 7 nach rechts oder links, dann kippt der Nocken 13 entsprechend nach rechts oder links, so daß die Zahnburstenachse 2 die gewünschte Pendelbewegung ausführt. Da die Nut 11 T-nutenförmig aus¬ gebildet ist, führt die Bewegung des Mitnehmers 9 nach vorn oder hinten dazu, daß sich die Zahnburstenachse 2 mit der Schwinge 12 entsprechend hin- und herbewegt.The toothbrush axis 2 also has a radially oriented cam 13 which is connected to the driver 9 by a pivot connection 14 such that it can oscillate about the longitudinal axis 3 together with the toothbrush axis 2, which is not possible for the driver 9, because it is held by the eccentric 7. In this exemplary embodiment, the swivel connection 14 is formed by a recess 15 in the end face 10 of the driver 9, in which the cam 13 engages and which each protrude from a tilting edge 16 which is directed against one side of the Cam 13 abuts, expanded in width up and down. Seen in Figure 2, the driver 9 moves by the movement of the eccentric 7 to the right or left, then the cam 13 tilts accordingly to the right or left, so that the toothbrush axis 2 performs the desired pendulum movement. Since the groove 11 is T-shaped, the movement of the driver 9 forwards or backwards causes the toothbrush axis 2 to move back and forth with the rocker 12 accordingly.
Zu erkennen ist in Figur 2 auch die Achse 17, welche mit¬ tig durch das Kronenrad 6 hindurchführt und dieses sowie den Exzenter 7 trägt. Um diese Achse 17 kann bei ent¬ sprechender Ausbildung des Zahnbürstengehäuses sein vor¬ derer Bereich mit der Zahnburstenachse 2 relativ zu einem Bereich mit dem Elektromotor 4 abgeknickt werden.The axis 17 can also be seen in FIG. 2, which passes through the crown wheel 6 and carries it as well as the eccentric 7. If the toothbrush housing is designed accordingly, its front region with the toothbrush axis 2 can be bent relative to a region with the electric motor 4 about this axis 17.
Die Figur 3 zeigt ein rohrschellenartiges Federteil 25, in welchem die Achse 17 des Getriebes der Zahnbürste sitzt. Figur 4 verdeutlicht, daß dieses Federteil 25 in einem Halter 26 beweglich gehalten ist, so daß er sich, wie strichpunktiert angedeutet, verformen kann und da¬ durch der Achse 17 eine Bewegung in Richtung der Längs¬ achse 3 der Zahnburstenachse 2 ermöglicht.
FIG. 3 shows a tube-like spring part 25, in which the axis 17 of the gear of the toothbrush is seated. FIG. 4 illustrates that this spring part 25 is movably held in a holder 26, so that it can deform, as indicated by dash-dotted lines, and thereby enables movement in the direction of the longitudinal axis 3 of the toothbrush axis 2 through the axis 17.
