Fig. 1 bis 3 zeigen einen vorderen Teil einer Handzahnbürste 1, der mit einem Bürstenkopf 2 ausgestattet ist. Der Bürstenkopf 2 weist einen Borstenträger 3 auf, in welchem jeweils aus einer Mehrzahl von Borsten gebildete Borstenbüschel 4, 5, 6 verankert sind. Mit 4 sind diejenigen Borstenbüschel bezeichnet, die im wesentlichen senkrecht zum Borstenträger 3 gerichtet sind. Es sind ausserdem zum Borstenträger schräggestellte Borstenbüschel 5, 6 vorhanden, wobei die Borstenbüschel 5 in Längsrichtung der Zahnbürste nach hinten, die Borstenbüschel 6 hingegen nach vorne geneigt sind. Der Neigungswinkel dieser Borstenbüschel 5, 6 gegenüber der Senkrechten kann bis zu 45° betragen (in der Zeichnung ist ein kleinerer Neigungswinkel dargestellt). Die freistehenden Enden aller Borsten bilden eine gegebenenfalls ebene Bürstfläche 10 (Fig. 3). Die Längsachse der Zahnbürste 1 ist in Fig. 2 mit 7 bezeichnet.1 to 3 show a front part of a manual toothbrush 1, which is equipped with a brush head 2. Of the Brush head 2 has a bristle carrier 3, in which tufts of bristles each formed from a plurality of bristles 4, 5, 6 are anchored. At 4, those are tufts of bristles referred to, which is substantially perpendicular to Bristle carrier 3 are directed. It is also a bristle holder inclined bristle tufts 5, 6 present, the bristle tufts 5 in the longitudinal direction of the toothbrush backwards, the bristle tufts 6, however, inclined forward are. The angle of inclination of these bristle tufts 5, 6 compared to the vertical can be up to 45 ° (in the Drawing is shown a smaller angle of inclination). The free ends of all bristles form one if necessary flat brush surface 10 (Fig. 3). The longitudinal axis of the Toothbrush 1 is designated 7 in FIG. 2.

Wie aus Fig. 2 ersichtlich sind die Borstenbüschel 4, 5, 6 nebeneinander in mehreren zur Längsrichtung der Zahnbürste rechtwinklig gerichteten Querreihen 14, 15, 16 angeordnet; gegebenenfalls sind drei Gruppen von je drei Querreihen 14 vorhanden, die durch die senkrecht zum Borstenträger 3 gerichteten Borstenbüschel 4 gebildet sind. Zwischen diesen Gruppen sind jeweils zwei Querreihen 15, 16 nebeneinander angeordnet, von denen die Querreihen 15 die nach hinten geneigten Borstenbüschel 5 enthalten, während in den Querreihen 16 die nach vorne geneigten Borstenbüschel 6 angeordnet sind, derart, dass sich die Borstenbüschel 5, 6 der benachbarten Querreihen 15, 16 gegenseitig kreuzen und paarweise ein X-förmige Anordnung bilden (vgl. insbesondere Fig. 1). Alle schräggestellten Borstenbüschel 5 bzw. 6 einer Querreihe 15 bzw. 16 weisen den gleichen Neigungswinkel auf. Der Neigungswinkel der Borstenbüschel 5 der einen Querreihe 15 eines Querreihenpaares 15, 16 gegenüber der Senkrechten gleicht dem negativen Neigungswinkel der Borstenbüschel 6 der anderen Querreihe 16, so dass ein in Längsrichtung symmetrisches X-Gebilde entsteht. Die beiden Querreihenpaare 15, 16 mit den sich kreuzenden, geneigten Borstenbüscheln 5, 6 sind in einem etwa einer durchschnittlichen Zahnbreite entsprechenden Abstand angeordnet.As can be seen from FIG. 2, the bristle tufts 4, 5, 6 side by side in several to the longitudinal direction of the toothbrush perpendicular rows 14, 15, 16 arranged; if necessary, three groups of three transverse rows are 14 available, which by the perpendicular to the bristle carrier 3 Bristle tufts 4 are formed. Between these Groups are two transverse rows 15, 16 next to each other arranged, of which the transverse rows 15 to the rear inclined bristle tufts 5 included while in the transverse rows 16 the bristle tufts 6 which are inclined towards the front are such that the bristle tufts 5, 6 of the cross rows 15, 16 cross each other and form an X-shaped arrangement in pairs (cf. in particular Fig. 1). All inclined bristle tufts 5 or 6 of a transverse row 15 and 16 have the same angle of inclination on. The angle of inclination of the tufts of bristles 5 a transverse row 15 of a transverse row pair 15, 16 opposite the vertical is equal to the negative angle of inclination Bristle tufts 6 of the other transverse row 16, so that an in Longitudinal symmetrical X-structure is created. The two Cross rows 15, 16 with the intersecting, inclined Tufts of bristles 5, 6 are roughly average Tooth width corresponding distance arranged.

Fig. 4 bis 6 zeigen eine weitere Variante einer mit einem Bürstenkopf 2a ausgestatteten Handzahnbürste 1a. Der Borstenträger, die aufrechtstehenden und geneigten Borstenbüschel sowie die entsprechenden Querreihen sind weiterhin mit den gleichen Bezugsziffern bezeichnet wie in Fig. 1 bis 3. Bei dieser Ausführungsform ist allerdings nur eine Gruppe von drei aus senkrecht zum Borstenträger 3 stehenden Borstenbüscheln 4 gebildeten Querreihen 14 vorhanden, die - in Längsrichtung der Zahnbürste gesehen - zwischen je zwei Paaren von Querreihen 15, 16 angeordnet ist, die mit schrägstehenden, sich paarweise kreuzenden Borstenbüscheln 5, 6 versehen sind. Auch bei dieser Variante bilden die freistehenden Borstenenden eine ebene Bürstfläche 10 (Fig. 6).4 to 6 show a further variant of one with a Brush head 2a equipped manual toothbrush 1a. The bristle carrier, the upright and inclined tufts of bristles and the corresponding cross rows are still designated by the same reference numerals as in FIG. 1 to 3. In this embodiment, however, there is only one Group of three standing perpendicular to the bristle carrier 3 Bristle tufts 4 transverse rows 14 formed, the - seen in the longitudinal direction of the toothbrush - between two pairs of transverse rows 15, 16 are arranged, the with sloping tufts of bristles crossing in pairs 5, 6 are provided. Form also with this variant the free-standing bristle ends have a flat brush surface 10 (Fig. 6).

Eine in Fig. 7 bis 9 dargestellte dritte Ausführungsform einer Handzahnbürste 1b mit einem Bürstenkopf 2b entspricht im wesentlichen der ersten Variante nach Fig. 1 bis 3; die Querreihen 14 weisen die gleiche Anzahl von Borstenbüscheln, aber die äussersten seitlichen Aussenbüschel 18, 19 jeder Querreihe 14 sind in Querrichtung der Zahnbürste nach aussen geneigt (Fig. 8 und 9). Auch den mit den in Längsrichtung geneigten Borstenbüscheln 5, 6 versehenen, mit der mittleren Gruppe von Querreihen 14 benachbarten Querreihen 15, 16 ist seitlich je ein Auswenbüschel 20, 21 bzw. 22, 23 zugeordnet, das jeweils sowohl in Längsrichtung, als auch in Querrichtung der Zahnbürste 1b nach aussen schräggestellt ist (vgl. Fig. 8). Die Aussenbüschel 18, 20, 22 bzw. 19, 21, 23 bilden auf diese Weise je eine seitliche Längsreihe 26, 27 von in Querrichtung nach aussen schräg abstehenden Borstenbüscheln. Die durch alle Borstenbüschelenden gebildete Bürstfläche 10 ist wiederum eben ausgestaltet (Fig. 9).A third embodiment shown in FIGS. 7 to 9 corresponds to a manual toothbrush 1b with a brush head 2b essentially the first variant according to FIG. 1 to 3; the transverse rows 14 have the same number of Bristle tufts, but the outermost side tufts 18, 19 of each transverse row 14 are in the transverse direction Toothbrush inclined outwards (Fig. 8 and 9). Also the with the bristle tufts 5, 6 inclined in the longitudinal direction provided, with the middle group of transverse rows 14 adjacent Transverse rows 15, 16 is a tuft at each side 20, 21 or 22, 23 assigned, each in both Longitudinal direction, as well as in the transverse direction of the toothbrush 1b is inclined towards the outside (see Fig. 8). The outside tufts 18, 20, 22 and 19, 21, 23 form on this One lateral longitudinal row 26, 27 each in the transverse direction tufts of bristles protruding outwards. The brush surface 10 formed by all ends of the tufts of bristles is again flat (Fig. 9).

In Fig. 10 bis 12 ist eine vierte Variante einer Handzahnbürste 1c mit einem Bürstenkopf 2c dargestellt, der eine Gruppe von vier und zwei Gruppen von zwei Querreihen 14 mit senkrecht zum Borstenträger 3 stehenden Borstenbüscheln 4 aufweist, zwischen denen jewils zwei Querreihen 15, 16 mit den zum Borstenträger 3 in Längsrichtung geneigten, sich paarweise kreuzenden Borstenbüscheln 5, 6 angeordnet sind. Bei dieser Variante überragen die schräggestellten Borstenbüschel 5, 6 in der Höhe die meisten der aufrechtstehenden Borstenbüschel 4; aber auch die vordere Gruppe von senkrecht zum Borstenträger 3 stehenden Borstenbüschel 4 weist unterschiedlich lange Borstenbüschel 4 auf, so dass im vorderen Bereich des Bürstenkopfes 2c ein in Längsrichtung geneigter, dem vorderen Ende des Bürstenkopfes 2c hinzu sich erhebender Bürstflächenteil 29 gebildet wird (Fig. 10).10 to 12 is a fourth variant of a manual toothbrush 1c with a brush head 2c, the one Group of four and two groups of two transverse rows 14 with bristle tufts standing perpendicular to the bristle carrier 3 4, between each of which two transverse rows 15, 16 with the bristle carrier 3 inclined in the longitudinal direction, bristle tufts 5, 6 crossing in pairs are arranged. In this variant, the inclined ones protrude Bristle tufts 5, 6 in height most of the upright tufts of bristles 4; but also the front one Group of bristle tufts perpendicular to the bristle carrier 3 4 has tufts 4 of different lengths on, so that in the front area of the brush head 2c longitudinally inclined, the front end of the brush head 2c in addition rising brush surface part 29 is formed will (Fig. 10).

Selbstverständlich könnte ein derartig geneigter Bürstflächenteil 29 auch den anderen vorstehend beschriebenen Ausführungsformen zugeordnet sein. Diese Ausführungsformen könnten aber auch mit in der Höhe die aufrechtstehenden Borstenbüschel 4 überragenden geneigten Borstenbüscheln 5, 6 ausgestattet sein.Of course, such an inclined brush surface part 29 also the other embodiments described above be assigned. These embodiments but could also stand upright at height Bristle tufts 4 projecting inclined bristle tufts 5, 6 be equipped.

Bei allen vorstehend beschriebenen Ausführungsformen von Zahnbürsten 1, 1a, 1b und 1c sorgen beim Zahnreinigungsvorgang die senkrecht zum Borstenträger 3 stehenden Borstenbüschel 4 vor allem für die Reinigung von Zahnflächen. Mit den in Längsrichtung der Zahnbürste schräggestellten Borstenbüscheln 5, 6 werden die Zahnzwischenräume besser erreicht und der Zahnfleischsaum (d.h. der Bereich des Überganges Zähne/Zahnfleisch) wirkungsvoller behandelt. Beim Zahnreinigungsvorgang, d.h. bei der Hin- und Herbewegung der Zahnbürste in Längsrichtung kommen dabei bei Bewegung in einer Richtung die nach hinten geneigten Borstenbüschel 5 der Querreihen 15, bei der Bewegung in der anderen Richtung die anderen, nach vorne geneigten Borstenbüschel 6 der Querreihen 16 zur Wirkung, nämlich zum besseren Eindringen in die schwer erreichbaren Interdentalräume. Während diese in einer Richtung geneigten und in der einen Bewegungsrichtung wirksamen Borstenbüschel 5 bzw. 6 an den Zähnen anstossen und in die Interdentalräume gedrängt werden, werden die anders geneigten Borstenbüschel 6 bzw. 5 über die Zahnoberflächen geschleppt und üben eine Wischwirkung aus. In der anderen Bewegungsrichtung werden die Rollen der Borstenbüschel 5,6 getauscht. Durch diese in beiden Bewegungsrichtungen stattfindende Stoss-/Schleppwirkung der in Längsrichtung der Zahnbürste symmetrisch angeordneten, schrägstehenden Borstenbüschelreihen 15, 16 mit sich paarweise kreuzenden Borstenbüscheln 5, 6 wird eine doppelte Reinigungswirkung erreicht und eine hervorragende Massage des Zahnfleisches bewirkt. Die eine bessere Durchblutung des Gewebes bewirkende Massage hat eine positive Auswirkung auf die Gesunderhaltung des Zahnfleischsaumes.In all of the above-described embodiments of Toothbrushes 1, 1a, 1b and 1c take care of the tooth cleaning process the bristle tufts perpendicular to the bristle carrier 3 4 especially for cleaning tooth surfaces. With the toothbrush slanted in the longitudinal direction Tufts of bristles 5, 6 improve the interdental spaces reached and the gum line (i.e. the area of the Transition teeth / gums) treated more effectively. In the tooth cleaning process, i.e. in the float the toothbrush in the longitudinal direction come when moving the bristle tufts inclined backwards in one direction 5 of the transverse rows 15 when moving in the in the other direction the other bristle tufts inclined forward 6 of the transverse rows 16 to effect, namely to better penetration into the difficult to reach interdental spaces. While these are inclined in one direction and in the bristle tufts 5 effective in one direction of movement or 6 knock on the teeth and into the interdental spaces the bristle tufts are inclined differently 6 or 5 dragged over the tooth surfaces and have a wiping effect. In the other direction the roles of the tufts of bristles 5,6 are exchanged. By this taking place in both directions of movement Impact / drag effect in the longitudinal direction of the toothbrush symmetrically arranged, sloping rows of bristles 15, 16 with tufts of bristles crossing in pairs 5, 6 a double cleaning effect is achieved and an excellent massage of the gums. The massage that improves blood circulation in the tissue has a positive effect on maintaining health of the gumline.

Durch das Hervorstehen der der in Längsrichtung geneigten, sich kreuzenden Borstenbüscheln 5, 6 gegenüber den aufrechtstehenden Borstenbüscheln 4 (vgl. als Beispiel die vierte Variante gemäss Fig. 10 bis 12) wird der Effekt des Eindringens in die Zahnzwischenräume zusätzlich verstärkt.By the protrusion of the inclined in the longitudinal direction, intersecting bristle tufts 5, 6 compared to the upright Bristle tufts 4 (see, for example, the fourth variant according to FIGS. 10 to 12) the effect of Penetration into the interdental spaces additionally reinforced.

Die Neigung der Bürstfläche im vorderen Bereich 29 (Fig. 10) bewirkt eine bessere Anpassung an die Gebiss- und Zahnform.The inclination of the brush surface in the front area 29 (Fig. 10) causes better adaptation to the dentition and Tooth shape.
