The handle contains circumferential grooves (18), as well as several knobs (21) arranged in two rows extending at 45 degrees to each other along the handle to prevent the toothbrush rolling off a surface. The brush may be concave and integrally formed from the handle is used.

Description

Die Erfindung bezieht sich auf eine Hand-Zahnbürste mit einem Bürstenkopf und einem langgestreckten Griffteil.The invention relates to a hand toothbrush with a brush head and an elongated handle part.

Hand-Zahnbürsten sind Zahnbürsten, bei denen die Putzbewegung ausschließlich von der Hand, also manuell, erbracht wird. Der Bürstenkopf und der Griffteil sind daher drehfest miteinander verbunden. Der Querschnitt des Griffteils ist nicht wesentlich größer als der des Bürstenkopfes. Bekannte Hand-Zahnbürsten haben einen Griffteil, der einen dreieckigen oder rechteckigen Querschnitt und häufig eine geringe Querschnittsfläche aufweist. Beim Halten des Griffteiles in der Hand liegt mindestens eine der Flächen des Griffteiles derart in der Hand, daß der Anstellwinkel der Zahnbürste, und dadurch insbesondere der Anstellwinkel des Bürstenkopfes im Verhältnis zu der Hand festgelegt ist. Für eine gründliche Säuberung der Zähne sollte der Bürstenkopf einen Winkel von ungefähr 45° zu den Zähnen haben. Dieser optimale Bürstenkopf-Winkel kann bei den herkömmlichen Zahnbürsten nur durch Drehen des Handgelenks eingestellt werden. Dies ist unbequem und unter Umständen derart anstrengend, daß diese Haltung während des Putzens der Zähne nicht eingehalten werden kann. Zum Putzen des Ober- und Unterkiefers müssen verschiedene Anstellwinkel eingestellt werden, die ungefähr eine Winkeldifferenz von 90° zueinander haben. Diese Winkeldifferenz läßt sich bei Zahnbürsten-Griffteilen mit dreieckigem oder rechteckigem Querschnitt nur durch Schwenken des Handgelenkes oder Umgreifen einstellen.Hand toothbrushes are toothbrushes in which the cleaning movement is carried out exclusively by hand, i.e. manually. The brush head and the handle part are therefore connected to one another in a rotationally fixed manner. The cross section of the handle part is not significantly larger than that of the brush head. Known hand toothbrushes have a handle part that has a triangular or rectangular cross section and often has a small cross-sectional area. When the handle part is held in the hand, at least one of the surfaces of the handle part lies in the hand in such a way that the angle of attack of the toothbrush, and in particular the angle of attack of the brush head in relation to the hand, is fixed. For a thorough cleaning of the teeth, the brush head should have an angle of approximately 45 ° to the teeth. With conventional toothbrushes, this optimal brush head angle can only be set by turning the wrist. This is inconvenient and may be so strenuous that this posture cannot be maintained while brushing the teeth. To clean the upper and lower jaw, different angles of attack must be set, approximately one Have an angular difference of 90 ° to each other. In the case of toothbrush handle parts with a triangular or rectangular cross section, this angular difference can only be set by swiveling the wrist or reaching around.

Aufgabe der Erfindung ist es, die Handhabung einer Hand-Zahnbürste zu verbessern.The object of the invention is to improve the handling of a hand toothbrush.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.This object is achieved by the features of claim 1.

Der Griffteil der Zahnbürste hat im wesentlichen kreisförmigen Querschnitt, so daß durch Drehen des Griffteiles in einer Hand jeder Anstellwinkel des Bürstenkopfes eingestellt werden kann. Während die Hand in einer bequemen Stellung verbleibt, die das Putzen der Zähne erleichtert, wird die Zahnbürste in der Hand gedreht und der optimale Anstellwinkel des Bürstenkopfes auf diese Weise eingestellt. Es wird also nicht die Hand, sondern die in der Hand gehaltene Zahnbürste zum Einstellen des optimalen Anstellwinkels gedreht. Dadurch wird ein genaues Einstellen des optimalen Bürstenkopf-Anstellwinkels ermöglicht, ohne daß die Hand eine unbequeme oder ermüdende Haltung einnehmen muß. Ferner wird das Greifen und Halten des runden Griffes als angenehm empfunden. Das Zähneputzen wird daher erleichtert und in seinem Ergebnis verbessert.The handle part of the toothbrush has an essentially circular cross-section, so that by turning the handle part in one hand every angle of the brush head can be adjusted. While the hand remains in a comfortable position that makes brushing the teeth easier, the toothbrush is rotated in the hand and the optimal angle of the brush head is adjusted in this way. So it is not the hand that is turned, but the toothbrush that is held in the hand in order to set the optimal angle of attack. This enables a precise adjustment of the optimal brush head angle of attack without the hand having to take an uncomfortable or tiring posture. Furthermore, gripping and holding the round handle is perceived as pleasant. Brushing your teeth is therefore made easier and the result improved.

In einer bevorzugten Ausgestaltung ist der Griffteil im Querschnitt kreisrund ausgebildet. Dadurch kann der Griffteil in der Hand stufenlos auf jeden Anstellwinkel gedreht und in diesen Winkel gehalten werden.In a preferred embodiment, the grip part is circular in cross section. As a result, the handle part can be rotated continuously in the hand to any angle of attack and held at this angle.

Der runde Griff bietet außerdem in Längsrichtung eine hohe Stabilität gegen Biegemomente.The round handle also offers great stability in the longitudinal direction against bending moments.

Vorzugsweise ist der Griffteil im Querschnitt gleichseitig vieleckig, insbesondere achteckig, ausgebildet. Mindestens sind jedoch fünf- bis sechseckige Querschnittsformen vorgesehen. Auf diese Weise läßt sich der Griffteil in der Hand in kleinen Stufen in bestimmte Bürstenkopf-Anstellwinkel einstellen. Durch die Seitenflächen des Griffteils ist der Griffteil griffiger und dadurch gegen Verdrehen in der Hand gesichert.The grip part is preferably polygonal in cross section, in particular octagonal, in cross section. However, at least pentagonal to hexagonal cross-sectional shapes are provided. In this way, the handle part in the hand can be adjusted in small increments to certain brush head angles of attack. Due to the side surfaces of the handle part, the handle part is easier to grip and therefore secured against twisting in the hand.

In einer bevorzugten Ausgestaltung weist der Griffteil in Umfangsrichtung verlaufende Nuten auf. Diese Nuten erhöhen die Griffigkeit des Griffteils in axialer Richtung, so daß insbesondere bei axialen Putzbewegungen der Griffteil der Zahnbürste fest in der Hand gehalten werden kann und gegen axiales Verrutschen gesichert ist.In a preferred embodiment, the grip part has grooves running in the circumferential direction. These grooves increase the grip of the grip part in the axial direction, so that the grip part of the toothbrush can be held firmly in the hand and is secured against axial sliding, in particular during axial cleaning movements.

Vorzugsweise weist der Griffteil Noppen auf, die ein Rollen bzw. Kippen des Griffteiles auf einer Unterlage verhindern. Dies ist insbesondere bei einem Griffteil mit kreisrundem Querschnitt sinnvoll, um zu vermeiden, daß der auf einer Unterlage liegende Griffteil der Zahnbürste so weit kippen kann, so daß der Bürstenkamm des Bürstenkopfes mit der Unterlage in Berührung käme. Durch die Noppen wird ein derartiges Kippen des Griffteiles vermieden, so daß eine Verschmutzung des Bürstenkammes durch Berührung mit der Unterlage ausgeschlossen ist. Die Noppen können dabei so klein ausgestaltet sein, daß sie das Halten des Griffteiles in der Hand nicht behindern.The grip part preferably has knobs which prevent the grip part from rolling or tilting on a base. This is particularly useful in the case of a grip part with a circular cross section, in order to avoid that the grip part of the toothbrush lying on a base can tilt so far that the brush comb of the brush head would come into contact with the base. Such a tilting of the handle part is avoided by the knobs, so that contamination of the brush comb by contact with the base is excluded. The knobs can be designed so small that they do not hinder the holding of the handle part in the hand.

Vorzugsweise sind mehrere Noppen in einer Reihe in Längsrichtung hintereinander angeordnet. Dadurch können die Noppen klein ausgestaltet werden, wobei die Wirkung weniger Noppen in einer Reihe ausreichend ist, um ein Kippen des Griffteiles zu vermeiden.A plurality of knobs are preferably arranged one behind the other in a row in the longitudinal direction. As a result, the knobs can be made small, the effect of fewer knobs in a row being sufficient to prevent the handle part from tipping over.

Vorzugsweise sind zwei Noppen-Längsreihen vorgesehen, die derart angeordnet sind, daß der Bürstenkamm des Bürstenkopfes ungefähr die Winkelhalbierende zwischen beiden Noppenreihen bildet. Bei dieser Konfiguration kann der Griffteil ungefähr in einem Bereich von 180° auf einer Unterlage drehen, ohne daß jedoch der Bürstenkamm die Unterlage berühren kann.Preferably two longitudinal rows of nubs are provided, which are arranged such that the brush comb of the brush head forms approximately the bisector between the two rows of nubs. With this configuration, the handle part can rotate approximately in a range of 180 ° on a base without the brush comb being able to touch the base.

In einer bevorzugten Ausgestaltung weist der Bürstenkamm eine in Längs- und/oder Querrichtung konkave Konturlinie auf. Dadurch ist der Bürstenkamm der Kontur der Zähne angepaßt und die Putzwirkung verbessert.In a preferred embodiment, the brush comb has a concave contour line in the longitudinal and / or transverse direction. As a result, the brush comb is adapted to the contour of the teeth and the cleaning effect is improved.

Der Bürstenkopf und das Griffteil können einstückig miteinander ausgebildet sein. Der Bürstenkopf oder der Bürstenkamm kann jedoch auch trennbar und auswechselbar an dem Griffteil befestigt sein.The brush head and the handle part can be integrally formed with one another. However, the brush head or the brush comb can also be attached to the handle part in a separable and replaceable manner.

Im folgenden werden unter Bezugnahme auf die Zeichnungen Ausführungsbeispiele der Erfindung näher erläutert.Exemplary embodiments of the invention are explained in more detail below with reference to the drawings.

In Figur 1 ist eine Hand-Zahnbürste 10 dargestellt, die aus einem Bürstenkopf 12, einem Griffteil 14 und einem Halsteil 15 besteht, der den Bürstenkopf 12 und das Griffteil 14 verbindet. Der Bürstenkopf 12, der Griffteil 14 und der Halsteil 15 sind aus Kunststoff und einstückig miteinander ausgebildet.FIG. 1 shows a hand toothbrush 10 which consists of a brush head 12, a handle part 14 and a neck part 15 which connects the brush head 12 and the handle part 14. The brush head 12, the handle part 14 and the neck part 15 are made of plastic and are integrally formed with one another.

Wie in Figur 2 dargestellt, ist der Griffteil 14 im Querschnitt kreisrund und zum freien Ende hin sich leicht verjüngend ausgebildet. Dadurch liegt der Griffteil 14 gut in der Hand und die Zahnbürste kann in jedem beliebigen Winkel in der Hand gehalten werden. In dem an den Halsteil 15 angrenzenden Griffbereich 16 des Griffteiles 14 sind in zehn Umfangsrichtung verlaufende Ringnuten 18 vorgesehen, die eine Tiefe von ungefähr 1 mm haben. Die Breite der Nuten 18 beträgt ebenfalls ungefähr 1 mm, während die Breite der zwischen den Nuten 18 liegenden ringförmigen Stege 19 ungefähr 2 mm beträgt.As shown in Figure 2, the handle portion 14 is circular in cross-section and slightly tapered towards the free end. As a result, the grip part 14 lies well in the hand and the toothbrush can be held in the hand at any angle. In the grip area 16 of the grip part 14 adjoining the neck part 15, annular grooves 18 are provided which extend in ten circumferential directions and have a depth of approximately 1 mm. The width of the grooves 18 is also approximately 1 mm, while the width of the annular webs 19 lying between the grooves 18 is approximately 2 mm.

Auf fünf der acht Stege 19 sind jeweils zwei Noppen 21,22 vorgesehen, die ungefähr 1 mm von dem jeweiligen Steg 19 abstehen. Wie in Figur 2 zu erkennen ist, sind die Noppen 21,22 zueinander ungefähr in einem Winkel von 90° angeordnet, wobei sie einen Bürstenkamm 24 des Bürstenkopfes 12 winkelhalbierend zwischen sich einschließen. Die fünf Noppen 21,22 einer Reihe sind in Längsrichtung hintereinander auf einer Linie angeordnet. Die Noppen 21,22 verhindern ein Rollen bzw. Kippen des Griffteiles 14 auf einer Unterlage über einen bestimmten Punkt hinaus, so daß der Bürstenkamm 24 des Bürstenkopfes 12 nicht mit der Unterlage in Berührung kommen kann, und dadurch eine Verschmutzung des Bürstenkopfes 12 durch die Unterlage ausgeschlossen wird.Five knobs 21, 22 are provided on five of the eight webs 19, which protrude approximately 1 mm from the respective web 19. As can be seen in FIG. 2, the knobs 21, 22 are arranged at an angle of approximately 90 ° to one another, enclosing a brush comb 24 of the brush head 12 bisecting the angle between them. The five knobs 21, 22 of a row are arranged one behind the other on a line in the longitudinal direction. The knobs 21, 22 prevent the handle part 14 from rolling or tipping over a base beyond a certain point, so that the brush comb 24 of the brush head 12 cannot come into contact with the base, and thus contamination of the brush head 12 from the base is excluded.

Der Griffbereich 16 hat ungefähr einen Durchmesser von 11 mm, während das freie Ende 17 einen Durchmesser von ungefähr 9 mm hat. Der Halsteil 15 ist im Querschnitt rund ausgebildet und hat einen Durchmesser von ungefähr 6 mm, kann jedoch auch rechteckig ausgebildet sein. In jedem Fall weist er jedoch einen geringeren Querschnitt als der Griffbereich 16 auf, so daß der Bürstenkopf 12 gegenüber dem Griffteil 14 leicht federnd befestigt ist.The grip area 16 has a diameter of approximately 11 mm, while the free end 17 has a diameter of approximately 9 mm. The neck part 15 is round in cross section and has a diameter of approximately 6 mm, but can also be rectangular. In any case, however, it has a smaller cross section than the handle area 16, so that the brush head 12 is slightly resiliently fastened relative to the handle part 14.

Wie in Figur 2 dargestellt ist, ist die Konturlinie 26 des Bürstenkammes 24 in der Querebene konkav ausgebildet. Auch die Konturlinie 28 des Bürstenkammes in der Längsebene ist konkav ausgebildet, wie in Fig 3 gezeigt. Durch die konkave Gestaltung der Bürstenkopfkontur wird eine gleichmäßige Reinigungswirkung des Bürstenkammes auf den größtenteils konvex geformten Zahnoberflächen erreicht.As shown in Figure 2, the contour line 26 of the brush comb 24 is concave in the transverse plane. The contour line 28 of the brush comb in the longitudinal plane is also concave, as shown in FIG. 3. The concave design of the brush head contour achieves a uniform cleaning effect of the brush comb on the largely convex tooth surfaces.

In den Figuren 4 bis 6 ist eine zweite Ausführungsform einer Zahnbürste 30 dargestellt, die sich von der ersten Ausführungsform der Figuren 1 bis 3 dadurch unterscheidet, daß der Griffteil 34 im Querschnitt gleichseitig achteckig ausgebildet ist, wie in Figur 5 dargestellt. Dabei werden von den Nuten 38 Stege 39 mit ebenfalls achteckigem Querschnitt gebildet. Der Bürstenkopf 12 gleicht dem Bürstenkopf 12 der Zahnbürste 10 der Figuren 1 bis 3. Die Maße der Zahnbürste 30 sind ungefähr gleich den Maßen der Zahnbürste 10 der Figuren 1 bis 3.FIGS. 4 to 6 show a second embodiment of a toothbrush 30, which differs from the first embodiment of FIGS. 1 to 3 in that the handle part 34 is of an octagonal cross section, as shown in FIG. 38 grooves 39 are also formed from the grooves with an octagonal cross section. The brush head 12 is similar to the brush head 12 of the toothbrush 10 of FIGS. 1 to 3. The dimensions of the toothbrush 30 are approximately the same as the dimensions of the toothbrush 10 of FIGS. 1 to 3.

Die Längskanten 40 des Griffteiles bieten beim Halten des Griffteiles 34 in der Hand einen guten Halt des Griffteiles gegen Verdrehen, während die Nuten 38 einen guten Halt gegen Verrutschen in axialer Richtung gewähren.The longitudinal edges 40 of the grip part offer a good grip of the grip part against twisting while holding the grip part 34 in the hand, while the grooves 38 provide a good grip against slipping in the axial direction.

Ferner bieten die Umfangsflächen 41 des Griffteiles 34 Aufstandflächen, auf denen die Zahnbürste 12 auf einer Unterlage abgestellt werden kann. Die Zahnbürste 30 ist durch die Außenflächen 41 gegen Rollen und Kippen gesichert, so daß der Bürstenkamm 24 des Bürstenkopfes 12 nicht mit dem Untergrund in Berührung kommt und daher nicht verschmutzen kann.Furthermore, the circumferential surfaces 41 of the grip part 34 offer contact surfaces on which the toothbrush 12 can be placed on a base. The toothbrush 30 is secured by the outer surfaces 41 against rolling and tilting, so that the brush comb 24 of the brush head 12 does not come into contact with the surface and therefore cannot become dirty.
