Abstract

The toothbrush design is intended to provide simultaneously a cleaning effect for the entire surface of the teeth, as well as for the gum parts. It has several brushes (4), driven by an electric motor, fitted on the free front ends of brush axes (2). The latter protrude from the motor retaining housing (1) which serves simultaneously as the hand grip for the brush tools. The brushes are of polygonal shape and cross section in relation to the rotary brush axis. The polygon corners are connected by convex curves. Preferably a two-corner section is used. A triangular section, however, may be used. In any case all the brushes are of the same polygonal shape. The brush axes are typically at such distance that the surfaces swept by the polygonal brushes partly intersect during rotation, the brush axes being yieldable and flexible.

Description

Zahnputzgerät mit mehreren motorisch drehan<je- Toothbrushing device with several motorized rotating

triebenen Bürstenkörpern Die Erfindung bezieht sich auf ein Zahnputzgerät mit mehreren motorisch drehangetriebenen Bürstenkörpern, welche an den vorderen freien Enden von Bürstenachsen angeordnet sind, die beabstandet zueinander von einem vorzugsweise gleichzeitig als Handhabe ausgebildeten, den Motor aufnehmenden Gehäuse vorstehen. driven brush bodies The invention relates to a toothbrushing device with several motorized rotating brush bodies, which are attached to the front free ends of brush axes are arranged, which are spaced apart from one another by a preferably at the same time designed as a handle, the motor receiving housing protrude.

Motorisch angetriebene, elektrische Zahnbürsten sind in mannigfachen Ausführungen zahlreich bekannt. Teilweise arbeiten sie mit in bestimmter Amplitude und Frequenz schwingenden Bürsten und teilweise mit rotierenden Bürsten.Motor-driven, electric toothbrushes are available in a variety Numerous versions known. Sometimes they work with in a certain amplitude and frequency oscillating brushes and partly with rotating brushes.

Bei elektrischen Zahnbürsten mit rotierenden Bürsten sind auch Anordnungen bekannt, bei denen mehrere Bürsten, die an beabstandeten Drehachsen angeordnet sind, in der Benutzungslage den zu reinigenden Zahn umgeben. Mit den bisher bekannt gewordenen elektrischen Zahnbürsten ist aber eine vollständige flächendeckende, auch in Vertiefungen wirkende Reinigung der Zähne nicht immer möglich.There are also arrangements for electric toothbrushes with rotating brushes known in which several brushes, which are arranged on spaced axes of rotation, surround the tooth to be cleaned in the position of use. With the ones that have become known so far Electric toothbrushes are, however, a complete area covering, even in depressions acting Cleaning the teeth is not always possible.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Zahnputzgerät der eingangs genannten Art die Bürstenkörper so auszubilden und anzuordnen, dass eine vollständige flächendeckende Reinigung aller Zahn-und Schleimhautanteile, die regelmässiger Pflege bedürfen, tatsächlich wirksam erreicht werden kann.The invention is based on the object of a toothbrushing device of the type mentioned to train and arrange the brush body so that a complete area-wide cleaning of all tooth and mucous membrane parts that require regular maintenance, can actually be achieved effectively.

Zur Lösung dieser Aufgabe wird erfindungsgemäss vorgeschlagen, dass die Bürstenkörper im Querschnitt zur Bürstendrehachse die Form eines Vieleckes haben, welches zwischen den Ecken durch konvex gekrümmte Kurven verbunden ist. Die im Querschnitt als gekrümmte Kurven bezeichneten Teile sind am Bürstenkörper selbst, der eine mehr oder weniger-große axiale Erstreckung hat, teilzylindrische gewölbte Flächen. Diese vorzugsweise zweieckige oder dreieckige Ausbildung der Bürstenkörper gestattet eine wesentlich wirksamere flächendeckende Reinigung der Zähne als es mit bisher bekannten, rotationssymmetrisch ausgebildeten Bürstenkörpern möglich war.To solve this problem, it is proposed according to the invention that the brush bodies have the shape of a polygon in the cross-section to the brush axis of rotation, which is connected between the corners by convex curved curves. The in cross section Parts known as curved curves are on the brush body itself, the one more or less-large axial extent, part-cylindrical curved surfaces. These preferably two-cornered or triangular design of the brush body allows one much more effective comprehensive cleaning of the teeth than with previously known, rotationally symmetrical brush bodies was possible.

In besonders zweckmässiger Ausgestaltung der Erfindung haben die Bürstenachsen einen solchen Abstand zueinander, dass sich die von den Vieleckformen der Bürstenkörper bei der Rotation überstrichenen Flächen teilweise überschneiden. Dadurch ist der flächendeckende Angriff der Bürstenkörper am Zahn weiterhin erhöht.In a particularly expedient embodiment of the invention, the brush axes such a distance from each other that the polygonal shapes of the brush body partially overlap areas swept during rotation. This is the Area-wide attack of the brush body on the tooth continues to increase.

Die Anpassung bzw. Anschmiegung der Bürstenkörper an verschiedene Zahngrößen und -formen ist dadurch erleichtert, dass in weiterer zweckmässiger Ausgestaltung der Erfindung die Bürstendrehachsen biegeelastisch ausgebildet sind.The adaptation or nestling of the brush body to different Tooth sizes and shapes is facilitated by the fact that in a further expedient embodiment the Invention, the brush axes of rotation are designed to be flexible.

Zweckmässige Ausführungsformen der Erfindung werden anhand der beigefügten Zeichnung beispielsweise beschrieben.Expedient embodiments of the invention are based on the attached Drawing described for example.

Es zeigen Fig. 1 perspektivisch ein erfindungsgemässes Zahnputzgerät; Fig. 2 schematisch den Angriff der erfindungsgemässen Bürstenkörper bei der Behandlung eines Zahnes mit dem erfindungsgemässen Zahnputzgerät; Fig. 3 und 4 Schnittansichten bevorzugter Querschnittsformen der Bürstenkörper.1 shows a tooth cleaning device according to the invention in perspective; 2 schematically shows the attack of the brush bodies according to the invention during the treatment of a tooth with the tooth cleaning device according to the invention; 3 and 4 are sectional views preferred cross-sectional shapes of the brush body.

Das Zahnputzgerät umfasst ein Gehäuse 1, welches einen nicht dargestellten Elektromotor mit geeignetem Getriebe für den Drehantrieb von aus dem Gehäuse 1 vorstehenden Bürstendrehachsen 2 enthält. Der Druckschalter für die Inbetriebsetzung des Motors ist mit 3 bezeichnet. Die Bürstendrehachsen 2 sind zu der aus Fig. 2 näher ersichtlichen besseren Anpassung an verschiedene Zahngrößen und Zahnformen biegeeleastisch ausgebildet und tragen an ihrem vorderen Ende Bürstenkörper 4, die aus geeigneten Borsten gebildet sind. Die Bürstenkörper 4 sind im Schnitt gemäss Fig. 3 und 4 als Zweieck 5 (Fig.3) oder als Dreieck 6 (Fig. 4) ausgebildet, wobei zwischen den Ecken die Begrenzungsflächen bzw. die im Schnitt nach den Fig. 3 und 4 sichtbaren Kurven 7 bzw. 8 nach außen gekrümmt sind.The toothbrushing device comprises a housing 1, which has a not shown Electric motor with a suitable gear for the rotary drive of protruding from the housing 1 Contains brush axes of rotation 2. The pressure switch for starting the engine is denoted by 3. The brush axes of rotation 2 can be seen in more detail in relation to that of FIG Better adaptation to different tooth sizes and tooth shapes designed to be flexible and at their front end they carry brush bodies 4 which are formed from suitable bristles are. The brush bodies 4 are in section according to FIGS. 3 and 4 as a triangle 5 (FIG. 3) or designed as a triangle 6 (Fig. 4), the boundary surfaces between the corners or the curves 7 and 8 visible in the section according to FIGS. 3 and 4 to the outside are curved.

Aus Fig. 2 ist der flächendeckende wirksame Angriff der Bürstenkörper 4 eines Zahnputzgerätes nach Fig.1 an einem Zahn 9 ersichtlich. Neben der Möglichkeit derartiger im Querschnitt vieleckig ausgebildeter Bürstenkörper, die von den Vieleckformen bei der Rotation überstrichenen Flächen sich überschneiden zu lassen, besteht ein wesentlicher weiterer Vorteil derartig viel eckig ausgebildeter Bürstenkörper darin, daß in Verbindung mit der biegeelastischen Ausbildung der Bürstendrehachsen zusätzlich zu der Rotation der Bürsten eine Schwingung überlagert wird, die sich in einem unterschiedlich starken Andruck des Bürstenkörpers an den Zahn bzw. das zu massierende Zahnfleisch auswirkt.From Fig. 2 the area-wide effective attack of the brush body 4 of a toothbrushing device according to FIG. 1 can be seen on a tooth 9. Besides the possibility such brush body with a polygonal cross-section that is derived from the polygonal shapes There is a possibility of overlapping areas swept over during rotation Another significant advantage of such a large number of angular brush bodies in it, that in conjunction with the flexible design of the brush axes of rotation in addition a vibration is superimposed on the rotation of the brushes, which is different strong pressure of the brush body on the tooth or the gums to be massaged affects.

Die Erfindung ist nicht auf Zahnputzgeräte mit drei rotierenden Bürstenkörpern beschränkt. Auch kann die Drehrichtung der Bürstenkörper gleichsinnig oder gegensinnig sein.The invention does not apply to toothbrushes with three rotating brush bodies limited. The direction of rotation of the brush bodies can also be the same or opposite be.
