Abstract

The handle (1) and the bristle bearer (2) of a toothbrush are connected to one another via a hinge (9). The axis (10a, 11a) of rotation of the hinge (9) forms an angle ( alpha ) with the longitudinal axis (1a) of the handle (1). In a first position of the bristle bearer (2), the brush surface (5) extends approximately parallel to the longitudinal axis (1a) of the handle (1). If the bristle bearer (2) is rotated by 180 DEG , the brush surface (5) forms an angle with the longitudinal axis (1a) of the handle (1). The toothbrush can thus be changed over from a position for cleaning the front teeth to a position for cleaning the back teeth. <IMAGE>

Description

Die vorliegende Erfindung betrifft eine Zahnbürste gemäss Oberbegriff des Anspruches 1.The present invention relates to a toothbrush according to the preamble of claim 1.

Es sind verschiedene Zahnbürsten bekannt, bei denen der die Borsten tragende Borstenträger und der Handgriff ge­lenkig miteinander verbunden sind, was es ermöglicht, den Borstenträger in seiner Stellung bezüglich des Handgrif­fes zu ändern.Various toothbrushes are known in which the bristle holder carrying the bristles and the handle are connected to one another in an articulated manner, which makes it possible to change the position of the bristle holder with respect to the handle.

In der amerikanischen Patentschrift 1,532,522 und der deutschen Gebrauchsmusterschrift 82 17 254 sind Zahn­bürsten dieser Art gezeigt, bei denen der Borstenträger und der Handgriff mittels eines Drehgelenkes miteinander verbunden sind, dessen Drehachse wenigstens im Bereich des Drehgelenkes mit den Längsachsen des Borstenträgers und des Handgriffes fluchtet. Dies bedeutet, dass die durch die Borstenenden festgelegte Bürstfläche in jeder Stellung des Borstenträgers im wesentlichen immer etwa parallel zur Längsachse des Handgriffes verläuft.In the American patent specification 1,532,522 and the German utility model 82 17 254 toothbrushes of this type are shown, in which the bristle holder and the handle are connected to one another by means of a swivel joint, the axis of rotation of which, at least in the region of the swivel joint, is aligned with the longitudinal axes of the bristle holder and the handle. This means that the brush surface defined by the bristle ends essentially always runs approximately parallel to the longitudinal axis of the handle in each position of the bristle carrier.

In der französischen Patentschrift 611.386 ist eine Zahn­bürste gezeigt, bei der die Gelenkverbindung zwischen dem Handgriff und dem Borstenträger so ausgebildet ist, dass der Borstenträger um eineim wesentlichen rechtwinklig zur Längsachse des Handgriffes verlaufende Achse schwenkbar ist und zwischen zwei Stellungen umgestellt werden kann. In beiden Stellungen des Borstenträgers verläuft die Bürstfläche in einem Winkel zur Längsachse des Hand­griffes.French patent 611,386 shows a toothbrush in which the articulated connection between the handle and the bristle holder is designed in such a way that the bristle holder can be pivoted about an axis which is essentially perpendicular to the longitudinal axis of the handle and can be switched between two positions. In both positions of the bristle holder, the brush surface runs at an angle to the longitudinal axis of the handle.

Die Umstellbarkeit des Borstenträgers ermöglicht zwar bei allen vorstehend erwähnten Zahnbürsten ein leichteres und gründlicheres Reinigen eines grösseren Teils der Zähne eines Gebisses als dies mit Zahnbürsten ohne verstell­barem Borstenträger möglich ist. Doch ist es bei diesen vorbekannten Zahnbürsten nach wie vor schwierig, die hin­terer Zähne gut reinigen zu können.The adjustability of the bristle holder allows easier and more thorough cleaning of a larger part of the teeth of a bit in all toothbrushes mentioned above than is possible with toothbrushes without an adjustable bristle holder. However, it is still difficult with these previously known toothbrushes to be able to clean the rear teeth well.

Der vorliegenden Erfindung liegt nun die Aufgabe zugrun­de, eine Zahnbürste der eingangs genannten Art von ein­fachem Aufbau zu schaffen, deren Borstenträger ohne wei­teres so in seiner Lage bezüglich des Handgriffes ver­stellt werden kann, dass mühelos ein gleich gründliches Reinigen aller Zähne eines Gebisses möglich ist.The present invention has for its object to provide a toothbrush of the type mentioned simple construction, the bristle holder can be easily adjusted in position with respect to the handle so that an equally thorough cleaning of all teeth of a bit is possible.

Diese Aufgabe wird erfindungsgemäss durch die Merkmale des kennzeichnenden Teils des Anspruches 1 gelöst.According to the invention, this object is achieved by the features of the characterizing part of claim 1.

Dadurch, dass die Gelenkverbindung zwischen Borstenträger und Handgriff so ausgebildet ist, dass die Bürstfläche von einer ersten Stellung, in der sie etwa parallel zur Längsachse des Handgriffes verläuft, in eine zweite Stel­lung und umgekehrt bringbar ist, in der die Bürstfläche unter einem Winkel zur Längsachse des Handgriffes ver­läuft, lässt sich dieselbe Zahnbürste durch Umstellen des Borstenträgers relativ zum Handgriff ohne Schwierigkeiten an den jeweiligen Einsatzzweck, nämlich das Reinigen der Vorderzähne einerseits und das Reinigen der hinteren Zähne andererseits, anpassen.Characterized in that the articulated connection between the bristle holder and the handle is designed such that the brush surface can be brought from a first position, in which it runs approximately parallel to the longitudinal axis of the handle, to a second position and vice versa, in which the brush surface is at an angle to the longitudinal axis of the handle, the same toothbrush can be adjusted by moving the bristle holder relative to the handle without difficulty to the respective application, namely cleaning the front teeth on the one hand and cleaning the rear teeth on the other.

Im folgenden wird der Erfindungsgegenstand anhand der Zeichnung näher erläutert. Es zeigt rein schematisch:

  • Fig. 1 in Seitenansicht und teilweise im Schnitt eine erfindungsgemässe Zahnbürste mit dem Borsten­träger in der Stellung zum Reinigen der Vorder­zähne,
  • Fig. 2 ebenfalls in Seitenansicht und teilweise im Schnitt die Zahnbürste nach Fig. 1 mit dem Bor­stenträger in der Stellung zum Reinigen der Backenzähne, und
  • Fig. 3 In Seitenansicht bzw. im Schnitt den Bereich der Gelenkverbindung zwischen dem Borstenträger und dem Handgriff der Zahnbürste gemäss den Figuren 1 und 2.
The subject of the invention is explained in more detail below with reference to the drawing. It shows purely schematically:
  • 1 is a side view and partially in section of a toothbrush according to the invention with the bristle holder in the position for cleaning the front teeth,
  • Fig. 2 also in side view and partially in section, the toothbrush of FIG. 1 with the bristle holder in the position for cleaning the molars, and
  • 3 shows, in side view or in section, the area of the articulated connection between the bristle holder and the handle of the toothbrush according to FIGS. 1 and 2.

Die in den Figuren 1 und 2 gezeigte Zahnbürste besteht aus einem geraden Handgriff 1 und einem Borstenträger 2 mit einer Bürste 3, die durch Borsten 4 gebildet ist, deren Enden eine Bürstfläche 5 bilden. Im gezeigten Ausführungsbeispiel liegt diese Bürstfläche 5 in einer Ebene, die in den Figuren mit E bezeichnet ist. Es ist selbstverständlich auch denkbar, die Bürstfläche 5 statt eben gekrümmt auszubilden. Die Borsten sind in einem Bor­stenhalteteil 6 gehalten, der gegenüber einem Halsteil 7 des Borstenträgers 2 abgewinkelt ist. Die Längsachse 6a des Borstenhalteteils 6 und die Längsachse 7a des Hals­teils 7 verlaufen demzufolge unter einem Winkel α zuei­nander.The toothbrush shown in Figures 1 and 2 consists of a straight handle 1 and a bristle holder 2 with a brush 3, which is formed by bristles 4, the ends of which form a brush surface 5. In the exemplary embodiment shown, this brush surface 5 lies in a plane which is denoted by E in the figures. It is of course also conceivable to design the brush surface 5 instead of being curved. The bristles are held in a bristle holding part 6 which is angled relative to a neck part 7 of the bristle holder 2. The longitudinal axis 6a of the bristle holding part 6 and the longitudinal axis 7a of the neck part 7 consequently run at an angle α to one another.

Der Borstenträger 2 und der Handgriff 1 sind über ein Drehgelenk 9 miteinander verbunden. Dieses Drehgelenk 9 besteht aus einem vom Borstenträger 2 abstehenden Gelenk­zapfen 10, der in ein Sackloch 11 im Handgriff 1 ein­greift.The bristle carrier 2 and the handle 1 are connected to one another via a swivel joint 9. This hinge 9 consists of a hinge pin 10 protruding from the bristle carrier 2, which engages in a blind hole 11 in the handle 1.

Die Längsachse 10a des Gelenkzapfens 10 fluchtet mit der Längsachse 7a des Halsteiles 7. Dies trifft auch für die Längsachse 11a des Sackloches 11 zu, die demzufolge mit der längsachse 1a des Handgriffes 1 einen Winkel α ein­schliesst. Der Borstenträger 2 lässt sich demzufolge um die Längsachse 7a bzw. die Längsachse 10a des Halsteiles 7 bzw. des Gelenkzapfens 10 verdrehen.The longitudinal axis 10a of the pivot pin 10 is aligned with the longitudinal axis 7a of the neck part 7. This also applies to the longitudinal axis 11a of the blind hole 11, which consequently forms an angle α with the longitudinal axis 1a of the handle 1. The bristle carrier 2 can accordingly be rotated about the longitudinal axis 7a or the longitudinal axis 10a of the neck part 7 or the pivot pin 10.

In der in Fig. 1 gezeigten Stellung des Borstenträgers 2 verläuft die Bürstfläche 5 und somit die Ebene E etwa pa­rallel zur Längsachse 1a des Handgriffes 1. Diese Stel­lung des Borstenträgers 2 erlaubt nun ein leichtes Hand­haben der Zahnbürste beim Reinigen der Vorderzähne.In the position of the bristle holder 2 shown in FIG. 1, the brush surface 5 and thus the plane E runs approximately parallel to the longitudinal axis 1 a of the handle 1. This position of the bristle holder 2 now permits easy handling of the toothbrush when cleaning the front teeth.

Wird nun der Borstenträger 2 um 180° gedreht, so nehmen Handgriff 1 und Borstenträger 2 die in Fig. 2 gezeigte gegenseitige Lage ein. In dieser Stellung des Borsten­trägers 2 bilden nun die Bürstfläche 5 (und damit auch die Ebene E) und die Längsachse 1a des Handgriffes 1 einen Winkel 2 α , der doppelt so gross ist wie die in den Figuren 1 und 2 mit α bezeichneten Winkel. Die Zahn­bürste ist an zwei Stellen jeweils um den Winkel α ab­gekröpft, wie das aus Fig. 2 deutlich hervorgeht.If the bristle holder 2 is now rotated by 180 °, the handle 1 and bristle holder 2 assume the mutual position shown in FIG. 2. In this position of the bristle carrier 2, the brush surface 5 (and thus also the plane E) and the longitudinal axis 1a of the handle 1 form an angle 2 a, which is twice as large as the angle designated by α in FIGS. 1 and 2. The toothbrush is bent at two points by the angle α, as can be clearly seen in FIG. 2.

In der in Fig. 2 gezeigten gegenseitigen Anordnung von Borstenträger 2 und Handgriff 1 lässt sich die Zahnbürste beim Reinigen der Hinterzähne leicht handhaben.In the mutual arrangement of bristle holder 2 and handle 1 shown in FIG. 2, the toothbrush can be easily handled when cleaning the rear teeth.

Um sicherzustellen, dass der Borstenträger 2 in seiner jeweiligen Stellung bezüglich des Handgriffes 1 festge­halten ist, müssen Arretiermittel vorgesehen werden, wel­che ein ungewolltes Verdrehen des Borstenträgers 2 bezüg­lich des Handgriffes 1 verhindern. Eine solche Arretie­rung kann beispielsweise durch einen entsprechend ausge­bildeten Passitz zwischen dem Gelenkzapfen 10 und dem Sackloch 11 erreicht werden. Die zwischen dem Gelenk­zapfen 10 und der Wandung des Loches 11 auftretenden Rei­bungskräfte verhindern ein ungewolltes Verdrehen des Bor­stenträgers 2, lassen jedoch bei entsprechender Kraftan­wendung ein Umstellen des Borstenträgers 2 zu.In order to ensure that the bristle holder 2 is held in its respective position with respect to the handle 1, locking means must be provided which prevent the bristle holder 2 from being rotated unintentionally with respect to the handle 1. Such locking can be achieved, for example, by a suitably designed fit between the pivot pin 10 and the blind hole 11. The frictional forces occurring between the pivot pin 10 and the wall of the hole 11 prevent the bristle carrier 2 from being rotated unintentionally, but allow the bristle carrier 2 to be rearranged when the appropriate force is applied.

Von den verschiedenen weiteren Möglichkeiten zur Ausbil­dung der Arretiermittel ist in Fig. 3 rein schematisch eine Variante gezeigt. Bei dieser Ausführungsform ist an der Stirnseite 12 des Halsteiles 7 des Borstenträger 2 ein Vorsprung 13 vorgesehen, der mit zwei sich diametral gegenüberliegenden Vertiefungen 14 und 15 zusammenwirkt, die an der Stirnseite 16 des Handgriffes 1 angeordnet sind. In den beiden in Fig. 1 und 2 gezeigten Stellungen des Borstenträgers 2 greift der Vorsprung 13 entweder in die Vertiefung 14 oder die Vertiefung 15 im Handgriff 1 ein. Es versteht sich, dass anstelle des Vorsprunges 13 eine Vertiefung vorgesehen werden kann, während anstelle der beiden Vertiefungen 14, 15 zwei Vorsprünge vorzusehen sind.A variant of the various other possibilities for the formation of the locking means is shown purely schematically in FIG. 3. In this embodiment, a projection 13 is provided on the end face 12 of the neck part 7 of the bristle carrier 2, which cooperates with two diametrically opposite recesses 14 and 15 which are arranged on the end face 16 of the handle 1. In the two positions of the bristle carrier 2 shown in FIGS. 1 and 2, the projection 13 engages either in the depression 14 or in the depression 15 in the handle 1. It goes without saying that a depression can be provided instead of the projection 13, while two projections are to be provided instead of the two depressions 14, 15.

Das Drehgelenk 9 kann auch anders als wie gezeigt ausge­bildet werden. So lässt sich der Gelenkzapfen 10 statt am Borstenträger 2 am Handgriff 1 anbringen, während im Bor­stenträger 2 das Sackloch 11 ausgebildet wird.The swivel joint 9 can also be designed differently than shown. Thus, the pivot pin 10 can be attached to the handle 1 instead of the bristle holder 2, while the blind hole 11 is formed in the bristle holder 2.

Anstelle der in den Figuren gezeigten Ausführungsform eines Drehgelenkes kann auch ein Drehgelenk vorgesehen werden, dessen Drehachse rechtwinklig zur Längsachse 1a des Handgriffes 1 und parallel zur Ebene E verläuft. An­ders ausgedrückt steht dann die Drehachse rechtwinklig zur Zeichenebene. Auch bei einer solchen Ausführungsform eines Drehgelenkes muss eine geeignete Arretierung vorge­sehen werden, um den Borstenträger 2 in den beiden gewün­schten Stellungen zu arretieren. Diese Arretiervorrich­tung kann beispielsweise als Rasteinrichtung ausgebildet werden.Instead of the embodiment of a swivel joint shown in the figures, a swivel joint can also be provided, the axis of rotation of which runs perpendicular to the longitudinal axis 1a of the handle 1 and parallel to the plane E. In other words, the axis of rotation is perpendicular to the plane of the drawing. In such an embodiment of a swivel joint, a suitable locking device must also be provided in order to lock the bristle holder 2 in the two desired positions. This locking device can for example be designed as a locking device.

Daneben ist es auch denkbar, statt eines Drehgelenkes ein Kugelgelenk mit entsprechenden Arretiermitteln vorzuse­hen.In addition, it is also conceivable to provide a ball joint with corresponding locking means instead of a swivel joint.

Obschon die vorliegende Erfindung anhand einer Zahnbürste mit abgewinkeltem Borstenträger beschrieben wurde, ist es selbstverständlich auch möglich, die erfindungsgemässe Idee bei einer Zahbürste vorzusehen, deren Borstenträger nicht abgewinkelt ist.Although the present invention has been described with reference to a toothbrush with an angled bristle holder, it is of course also possible to provide the inventive idea for a toothbrush whose bristle holder is not angled.
