Description

Die Erfindung betrifft eine Zahnbürste mit länglichem, quadratischem und/oder rundem Borstenfeld, welches aus einzelnen, nebeneinander an einem Bürstenkörper angeordneten und gegenüber diesen hochstehenden Borstenbündeln oder Borstenbüscheln gebildet ist, wobei wenigstens einzelne Borstenbündel an dem dem Bürstenkörper abgewandten Nutzungsende gegenüber einer etwa parallel zum Bürstenkörper verlaufenden Ebene zumindest teilweise dadurch abgeschrägt und/oder dachförmig geformt sind, dass Borsten dieser Borstenbündel unterschiedlich weit hoch stehen, so dass die am Ende dieser Borstenbündel angeordneten Abschlussflächen als Schrägflächen oder als teilweise schräge Flächen ausgebildet sind, wobei diese Borstenbündel entlang gedachter gerader oder insbesondere bogenförmiger oder bei Rundbürsten zum Beispiel für elektrische Zahnbürsten kreisbogen- oder kreisförmiger Verbindungslinien am Bürstenkörper einander benachbart angeordnet sind.The invention relates to a toothbrush having an elongated, square and / or round bristle field, which is formed of individual, adjacent to a brush body and opposite this upstanding bristle bundles or bristle tufts, wherein at least individual bristle bundles on the brush body facing away from the use of an approximately parallel to the brush body extending plane at least partially beveled by and / or roof-shaped, that bristles of these bristle bundles are different high, so that the end of this bundle of bristles arranged end surfaces are formed as inclined surfaces or as partially inclined surfaces, said bristle bundles along imaginary straight or curved particular or in circular brushes, for example, for electric toothbrushes circular arc or circular connecting lines on the brush body are arranged adjacent to each other.

Derartige Zahnbürsten sind in vielfältiger Form als Handzahnbürsten oder als elektrische Zahnbürsten bekannt, bei denen an dem Borstenfeld jeweils ein Stiel angreift.Such toothbrushes are known in many forms as manual toothbrushes or as electric toothbrushes, in which a stem acts on the bristle field in each case.

Neben klassischen Borstenfeldern, bei denen die Nutzungsenden aller Borstenbündel in einer gemeinsamen Ebene liegen, wurden zahlreiche Vorschläge gemacht, um die Reinigung der gewölbten Zahnflächen und insbesondere auch der Interdentalräume zwischen benachbarten Zähnen zu verbessern und effektiver zu machen. Vor allem in den Interdentalräumen und auch schon in den Übergängen zu den Interdentalräumen des Gebisses ist mit üblichen Zahnbürsten die Reinigung oft unzureichend.In addition to classic bristle fields, where the ends of use of all bundles of bristles lie in a common plane, numerous proposals have been made to improve the cleaning of the curved tooth surfaces and in particular the interdental spaces between adjacent teeth and make more effective. Especially in the interdental spaces and even in the transitions to the interdental spaces of the dentition, cleaning with conventional toothbrushes is often inadequate.

Zahlreiche Vorschläge gehen dabei dahin, das Borstenfeld einer Handzahnbürste so zu gestalten, dass es von der Seite gesehen eine wellenförmige oder zickzackförmige Kontur hat in der Hoffnung, dass die höherstehenden Bereiche eines solchen Borstenfeldes in die Interdentalräume eingreifen.Numerous proposals are made to make the bristle field of a manual toothbrush so that it has a wavy or zigzag-shaped contour seen from the side in the hope that the higher areas of such a bristle field intervene in the interdental spaces.

Aus EP 1 112 009 A1 ist beispielsweise ein Bürstenkopf einer Handzahnbürste bekannt, bei welchem unterschiedlich lange Borstenbündel in Längsrichtung gesehen hintereinander angeordnet und dabei so abgeschrägt sind, dass jeweils die vordersten, hintersten und dazwischenliegende mittlere Borstenbündel die größere Höhe und dazwischen befindliche Borstenbündel eine geringere Höhe haben, wobei gleichzeitig Abschrägungen an den Nutzungsenden derart angeordnet sind, dass von der Seite gesehen zwei rinnenförmige Einbuchtungen an diesem Borstenfeld gebildet werden. Die Schrägflächen der abgeschrägten Borstenbündel sind dabei jeweils um 180° zueinander verdreht, so dass sie einander zugewandt beziehungsweise im Nachbarbereich voneinander abgewandt sind.Out EP 1 112 009 A1 For example, a brush head of a manual toothbrush is known in which differently long bristle bundles seen in the longitudinal direction arranged one behind the other and are tapered so that in each case the foremost, rearmost and intermediate middle bristle bundles the greater height and bristle bundles located therebetween have a lower height, at the same time chamfers the use ends are arranged such that seen from the side two channel-shaped indentations are formed on this bristle field. The oblique surfaces of the chamfered bristle bundles are each rotated by 180 ° to each other, so that they face each other or are facing away from each other in the neighboring area.

Aus US 6 260 227 B1 ist eine Handzahnbürste bekannt, bei welcher an den beiden in Längsrichtung dieses Borstenfeldes und der gesamten Zahnbürste verlaufenden gedachten Verbindungslinien Borstenbündel in Reihe angeordnet sind, die jeweils abwechselnd entgegengesetzt abgeschrägt sind, das heißt die Borstenbündel sind mit ihrem Abschrägungen ebenfalls jeweils um 180° gegeneinander verdreht angeordnet. Zwischen diesen äußeren Reihen mit an den Nutzungsenden abgeschrägten Borstenbündeln befinden sich weitere Borstenbündel mit geringerer oder gar keiner Abschrägung.Out US 6 260 227 B1 a hand toothbrush is known, in which at the two in the longitudinal direction of this bristle field and the entire toothbrush imaginary connecting lines bristle bundles are arranged in series, which are alternately oppositely chamfered, that is, the bristle bundles are also arranged with their bevels each rotated by 180 ° from each other , Between these outer rows with beveled bristle bundles at the end of use, there are further bristle bundles with less or no chamfer.

All diese Zahnbürsten mit mehr oder weniger sinnreich profilierten Oberflächen der Borstenfelder müssen voraussetzen, dass ein Benutzer die Zahnbürste relativ zu seinen Zähnen sehr präzise bewegt und gleichzeitig andrückt in der Weise, dass tatsächlich längere Borsten in die Interdentalzwischenräume eingreifen und die kürzeren Borsten gleichzeitig die gewölbten Oberflächen der Zähne beaufschlagen.All these toothbrushes profiled with more or less ingenious Bristle patch surfaces require that a user very precisely move and simultaneously press the toothbrush relative to its teeth so that actually longer bristles engage the interdental spaces and the shorter bristles simultaneously engage the domed surfaces of the teeth.

Bedenkt man jedoch, dass schon das Halten einer Zahnbürste, sei es eine Handzahnbürste, sei es eine elektrische Zahnbürste, von der Gewohnheit und der Anatomie des Benutzers abhängt und jeder den entsprechenden Stiel oder Griff unter einem unterschiedlichen Winkel in den Mund einführt, wird deutlich, dass die vorgegebene Orientierung der Schrägflächen an den Nutzungsenden der Borstenbündel dann nicht oder nicht wirksam in die Interdentalzwischenräume eingreifen können, wenn die Bürste zu schräg relativ zum Verlauf des Gebisses gehalten wird, so dass dann ein entsprechend verschlechterter Reinigungseffekt eintritt.However, bearing in mind that even holding a toothbrush, be it a manual toothbrush or an electric toothbrush, depends on the habit and anatomy of the user and each introduces the corresponding handle or handle at a different angle into the mouth, it becomes clear that that the predetermined orientation of the inclined surfaces at the use ends of the bristle bundles can not or not effectively intervene in the interdental spaces when the brush is held too obliquely relative to the course of the bit, so that then a correspondingly deteriorated cleaning effect occurs.

Dies gilt auch für elektrische Zahnbürsten, da der Benutzer auch diese willkürlich erfasst und in einer Weise in seinen Mund hält, wie es für ihn selbst am bequemsten erscheint. Da bei der Benutzung solcher Zahnbürsten nicht zu erkennen ist, wie durch abgeschrägte Borstenbündel gebildete Querrinnen oder dergleichen relativ zu den Zähnen orientiert sind, wird also der angestrebte Effekt allenfalls zufällig und in aller Regel nur unzulänglich erfüllt.This also applies to electric toothbrushes, as the user also grasps them arbitrarily and holds them in his mouth in a way that seems most comfortable to him. Since when using such toothbrushes can not be seen, as are formed by bevelled bristle bundles transverse grooves or the like are oriented relative to the teeth, so the desired effect is at most coincidental and usually met only inadequate.

Es besteht deshalb die Aufgabe, eine Zahnbürste der eingangs genannten Art, sei es eine Handzahnbürste, sei es eine elektrische Zahnbürste, zu schaffen, die der Benutzer nahezu beliebig in den Mund einführen kann, das heißt die auch unter verschiedenen Winkeln ihres Griffes gehalten und benutzt werden kann und dennoch eine intensive Reinigung der Zahnoberflächen und der Interdentalzwischenräume beziehungsweise der Übergänge dazwischen ermöglicht.It is therefore an object to provide a toothbrush of the type mentioned, be it a manual toothbrush, be it an electric toothbrush, which the user can insert almost anywhere in the mouth, that is also held and used at different angles of their grip become can and still allows intensive cleaning of the tooth surfaces and the interdental spaces or the transitions between them.

Zur Lösung dieser scheinbar widersprüchlichen Aufgabe ist bei einer derartigen Zahnbürste der eingangs genannten Art vorgesehen, dass wenigstens einzelne Borstenbündel des Borstenfeldes mit ihren Schrägflächen relativ zueinander und gegenüber den Verbindungslinien um unterschiedliche Winkel verdreht angeordnet sind, welche Winkel von 90° und von 180° abweichen.To solve this seemingly contradictory task is provided in such a toothbrush of the type mentioned that at least individual bristle bundles of the bristle field are arranged with their inclined surfaces relative to each other and against the connecting lines twisted at different angles, which angle of 90 ° and deviate from 180 °.

Im Gegensatz zu den vorbekannten Lösungen werden also die Schrägflächen nicht relativ zueinander so angeordnet, dass sie gemeinsame eine Dachform oder eine Rinne bilden, sondern sie werden relativ regellos angeordnet, so dass bei der Benutzung einer solchen Bürste mit unterschiedlichen oder gar wechselnden Winkelstellungen des Handgriffes relativ zum Gebiss dennoch immer wieder Schrägflächen die Zähne im Übergang zu dem Interdentalzwischenraum und in diesem und außerdem auch an ihren Oberflächen beaufschlagen, wobei dem Benutzer zu Hilfe kommt, dass die Borsten der Borstenbündel biegsam sind, so dass eine nahezu richtig in einen Zahnzwischenraum eingreifende Schrägfläche durch den Druck der Bürste vollständig in diesen Zwischenraum eingreift und gleitet.In contrast to the previously known solutions, therefore, the inclined surfaces are not arranged relative to each other so that they form a common roof shape or gutter, but they are relatively randomly arranged so that when using such a brush with different or even changing angular positions of the handle relative To denture again and again oblique surfaces act on the teeth in the transition to the interdental space and in this and also on their surfaces, the user comes to the aid that the bristles of the bristle bundles are flexible, so that an almost correctly intervening in a tooth space inclined surface the pressure of the brush completely engages in this gap and slides.

Durch die relativ regellose gegenseitige Anordnung von Schrägflächen treffen also immer wieder solche Schrägflächen auch "richtig" in die für die Reinigung besonders wichtigen Zahnzwischenräume und verbessern somit die Reinigungswirkung, obwohl an der Oberfläche des Borstenfeldes kein Relief einer Gebissinnen- oder -außenseite möglichst genau nachgebildet ist.Due to the relatively random mutual arrangement of inclined surfaces, such oblique surfaces always make "right" turns into the interdental spaces which are particularly important for cleaning and thus improve the cleaning effect, although no relief of a denture inside or outside is reproduced as exactly as possible on the surface of the bristle field ,

In scheinbar widersinniger Weise wird also von einer solchen Nachbildung des Gebiss-Reliefs abgesehen, aber ausgenutzt, dass mit Schrägflächen versehene Borstenbündel in Interdentalzwischenräumen eine gute Reinigungswirkung entfalten. Durch die mehr oder weniger unregelmäßige gegenseitige Verdrehung der Schrägflächen wird die Wahrscheinlichkeit erhöht, dass solche Schrägflächen in die Interdentalzwischenräume eingreifen und dort eine Reinigungswirkung erzielen, vor allem dann, wenn eine übliche, relativ lange Putzdauer vom Benutzer eingehalten wird.In a seemingly contradictory way is thus of such Reproduction of the denture relief apart, but exploited that provided with inclined surfaces bristle bundles in interdental spaces unfold a good cleaning effect. Due to the more or less irregular mutual rotation of the inclined surfaces, the probability is increased that such inclined surfaces intervene in the interdental spaces and achieve a cleaning effect, especially if a usual, relatively long cleaning time is maintained by the user.

Besonders günstig ist es dabei, wenn innerhalb des Borstenfeldes einander unmittelbar benachbarte Borstenbündel mit ihren Schrägflächen relativ zueinander verdreht angeordnet sind. Für je mehr Borstenbündel dies zutrifft, um so größer wird die Wahrscheinlichkeit, dass bei nahezu beliebigen individuellen Ansatzwinkeln der Zahnbürste doch ein oder mehrere Borstenbündel den jeweiligen Interdentalzwischenraum zwischen zwei Zähnen optimal erfasst und reinigt.It is particularly advantageous if within the bristle field directly adjacent bristle bundles are arranged with their inclined surfaces rotated relative to each other. For more bundles of bristles this is true, the greater the likelihood that at almost any individual approach angles of the toothbrush but one or more bristle bundles optimally captures and cleans the respective interdental space between two teeth.

Dabei kann eine weitere Ausgestaltung der Erfindung im Hinblick darauf, dass solche Borstenfelder eine Vielzahl von Borstenbündeln umfasst, vorsehen, dass einzelne, einander unmittelbar benachbarte oder aber durch zwischen ihnen befindliche Borstenbündel beabstandete Borstenbündel mit ihren Schrägflächen gegeneinander und/oder gegenüber einer gedachten Verbindungslinie um 90° und/oder um 180° gegeneinander verdreht angeordnet sind, dass aber weitere Borstenbündel des Borstenfeldes um einen oder mehrere verschiedene, demgegenüber abweichende Winkel verdreht angeordnet sind.In this case, a further embodiment of the invention with regard to the fact that such bristle fields comprises a plurality of bristle bundles, provide that individual, immediately adjacent or spaced by them bristle bundles bristle bundles with their inclined surfaces against each other and / or with respect to an imaginary connecting line to 90th ° and / or are arranged rotated by 180 ° from each other, but that more bristle bundles of the bristle field are arranged rotated by one or more different, contrasting angle.

Somit kann die Verteilung der Schrägflächen der einzelnen Borstenbündel in ihrer gegenseitigen relativen Position und Verdrehung noch mehr variiert werden und es können beispielsweise "Paare" von Borstenbündeln innerhalb des gesamten Borstenfeldes vorkommen, bei denen die jeweils höchsten Stellen der Schrägflächen unmittelbar aneinander grenzen, wenn diese zu dem Paar gehörenden beiden Borstenbündel mit ihren Schrägflächen relativ zueinander um 180° verdreht angeordnet sind. Gleichzeitig kann ein solches "Paar" jedoch insgesamt gegenüber anderen Borstenbündeln mit Schrägflächen um einen von 180° oder von 90° abweichenden Winkel verdreht angeordnet sein. Das Gleiche gilt für Borstenbündel mit Winkelstellungen von 90°, wobei auch eine relative Verdrehung benachbarter Borstenbündel um abweichende Winkel innerhalb des gesamten Borstenfeldes dazu führen kann, dass weiter voneinander entfernte Borstenbündel zufällig mit ihren Schrägflächen relativ zueinander in einem Winkel von 90° oder auch von 180° angeordnet sind. Dies kann dazu beitragen, dass eine Vielzahl von mit Schrägflächen an den Nutzungsenden versehene Borstenbündel mehr oder weniger zufällig relativ zueinander verdreht über das Borstenfeld verteilt sind und somit dem Benutzer bei unterschiedlichsten individuellen Haltungen der Bürste relativ zu seinem Gebiss immer wieder auch "idealorientierte" Borstenbündel bei der Reinigung der Zähne zur Verfügung stehen. Vor allem kann dabei entweder dafür gesorgt werden, dass jeweils einander benachbarte Borstenbündel um einen gleichen, relativ geringen Winkel zueinander verdreht sind, so dass gewissermaßen eine Reihe von innerhalb dieser Reihe jeweils um den selben Winkelbetrag zum Nachbar-Borstenbündel verdrehte Bündel vorhanden sind, es kann jedoch auch eine weitgehend zufällige gegenseitige verdrehte Lage angewandt werden.Thus, the distribution of the inclined surfaces of the individual bristle bundles in their mutual relative position and rotation can be varied even more and, for example, "pairs" of bristle bundles within the entire bristle field happen, in which the respective highest points of the inclined surfaces directly adjoin one another, when these belonging to the pair of two bristle bundles with their inclined surfaces are arranged rotated relative to each other by 180 °. At the same time, however, such a "pair" can be arranged as a whole rotated relative to other bristle bundles with inclined surfaces by an angle deviating from 180 ° or from 90 °. The same applies to bristle bundles with angular positions of 90 °, wherein a relative rotation of adjacent bundles of bristles to differing angles within the entire bristle field can cause that more distant bristle bundles coincidentally with their inclined surfaces relative to each other at an angle of 90 ° or even 180 ° are arranged. This can contribute to the fact that a multiplicity of bristle bundles provided with oblique surfaces at the ends of use are distributed more or less randomly relative to one another over the bristle field and therefore always provide the user with "ideal-oriented" bristle bundles relative to his dentition in the case of different individual positions of the brush the cleaning of the teeth are available. Above all, it can either be ensured that each neighboring bristle bundles are rotated by a same, relatively small angle to each other, so that in a sense a number of within this row each twisted by the same angular amount to the neighboring bristle bundle, it can however, a largely random mutual twisted position can also be applied.

Im Hinblick darauf, dass auch bereits Zahnreinigungsgeräte mit nur einem einzigen Borstenbündel zur gezielten Reinigung von Interdental-Zwischenräumen bekannt geworden sind, ist die vorgesehene Anordnung von Borstenbündeln mit abgeschrägten Nutzungsflächen in unterschiedlichen gegenseitigen Positionen als günstiger zum Reinigen von Interdentalzwischenräumen anzusehen, weil der Benutzer nicht mehr "genau zielen" muss, um einen jeweiligen Interdentalzwischenraum zu treffen, sondern weil die Vielzahl unterschiedlich orientierter Borstenbündel dazu führt, dass mit sehr großer Wahrscheinlichkeit immer wieder "richtig orientierte" Borstenbündel an den einzelnen Interdentalzwischenräumen angreifen, wenn der Benutzer seine Zahnbürste in üblicher, aber doch individueller Weise ansetzt und entlang seinen Zahnreihen insbesondere mit Auf- und Abbewegungen benutzt.In view of the fact that tooth cleaning devices with only a single bundle of bristles have already become known for the purpose of purposely cleaning interdental spaces, the proposed arrangement of bundles of bristles with bevelled surfaces of use is in different mutual positions Consider as cheaper for cleaning interdental spaces, because the user does not have to "aim exactly" to meet a respective interdental space, but because the large number of differently oriented bristle bundles leads to the fact that with very high probability again and again "correctly oriented" bristle bundles to the attack individual interdental spaces when the user attaches his toothbrush in the usual, but individual way and uses along its rows of teeth in particular with up and down movements.

Eine abgewandelte Ausführungsform der erfindungsgemäßen Zahnbürste, sei sie von Hand oder elektrisch betrieben, die vor allem auch darauf abzielt, die jeweils den Interdental-Zwischenräumen benachbarten Zahnoberflächen gut zu erfassen, kann bei einer erfindungsgemäßen Zahnbürste darin bestehen, dass in ihrem Borstenfeld mit Schrägflächen oder schrägstehender Fläche versehene Borstenbündel und Borstenbündel mit etwa horizontaler, gerundeter und/oder angespitzter oder anders konturierter Nutzungsfläche miteinander kombiniert sind und dass derartige verschieden gestaltete Borstenbündel innerhalb des Borstenfeldes einander unmittelbar benachbart und/oder jeweils als Gruppen angeordnet sind, innerhalb welchen Gruppen gleiche oder ähnliche Borstenbündel zusammengefasst sind, wobei innerhalb wenigstens einer Gruppe Borstenbündel mit Schrägflächen angeordnet sind, die gegeneinander oder gegenüber ihren gedachten Verbindungslinien um von 90° oder 180° abweichende Winkel verdreht zueinander angeordnet sind.A modified embodiment of the toothbrush according to the invention, be it manually or electrically operated, which also aims to capture well the respective tooth surfaces adjacent the interdental spaces, may consist in a toothbrush according to the invention in that in its bristle field with inclined surfaces or obliquely Surface provided bristle bundles and bristle bundles are combined with approximately horizontal, rounded and / or sharpened or differently contoured use surface and that such differently shaped bristle bundles within the bristle field immediately adjacent to each other and / or are arranged as groups, within which groups the same or similar bristle bundles are, wherein within at least one group of bristle bundles are arranged with inclined surfaces, which against each other or with respect to their imaginary connecting lines by 90 ° or 180 ° different angle are arranged twisted to each other.

Zum Beispiel könnte bei einer Handzahnbürste das längliche Borstenfeld an seinen beiden Enden, also an dem dem Handgriff zugewandten und an dem diesem entgegengesetzten Ende jeweils eine Gruppe von Borstenbündeln haben, die an ihren Enden eine ebene oder gerundete oder angespitzte oder andersartig geformte Nutzungsfläche bilden, also nicht zu den Borstebündeln mit schrägen Nutzungsflächen gehören, während dazwischen Borstenbündel mit erfindungsgemäß relativ zueinander angeordneten Schrägflächen vorgesehen sein könnten. Der Mittelbereich eines Borstenfeldes einer solchen Zahnbürste könnte dann also vor allem zum Reinigen der Interdentalzwischenräume hilfreich sein, während die benachbarten Bereiche überwiegend zur Reinigung der Zahnoberflächen dienen.For example, in the case of a manual toothbrush, the elongated bristle field could each have a group of bundles of bristles at its two ends, that is to say at the end facing the handle and at the end opposite thereto, which have a group of bristle bundles at their ends form flat or rounded or sharpened or differently shaped use surface, so do not belong to the bristle bundles with oblique use surfaces, while between bristle bundles could be provided with according to the invention relatively inclined surfaces. The central region of a bristle field of such a toothbrush could then be helpful, above all, for cleaning the interdental spaces, while the adjacent regions serve predominantly for cleaning the tooth surfaces.

Bei einer insbesondere elektrischen Zahnbürsten mit rundem Borstenfeld könnten ebenso häufig auf Kreisen angeordnete Borstenbündel gruppenweise in der vorbeschriebenen Weise gestaltet sein.In a particular electric toothbrushes with a round bristle field bristle bundles arranged on circles could also be designed in groups in the manner described above.

Einerseits könnten also jeweils ein oder zwei Bereiches des Borstenfeldes, bei einem länglichen Borstenfeld insbesondere die in Längsrichtung voneinander entfernten Bereiche dieses Borstenfeldes, mit Borstenbündeln versehen sein, deren Enden gerundet, angespitzt oder mit einer geraden Abschlussfläche versehen sind, und zwischen diesen Gruppen von Borstenbündeln könnte wenigstens eine Gruppe mit abgeschrägten oder dachförmig geformten Borstenbündeln angeordnet sein, die zumindest teilweise gegeneinander erfindungsgemäß verdreht angeordnet sind. Statt dessen oder zusätzlich könnten aber auch zwischen Gruppen von Borstenbündeln mit abgeschrägten Nutzflächen, die relativ zueinander verdreht angeordnet sind, Gruppen von Borstenbündeln mit ebenen, abgerundeten oder angespitzten Nutzungsflächen vorgesehen sein.On the one hand, in each case one or two regions of the bristle field, in the case of an elongated bristle field, in particular the regions of this bristle field which are remote from one another in the longitudinal direction, could be provided with bundles of bristles whose ends are rounded, sharpened or provided with a straight end surface, and between these groups of bristle bundles at least one group may be arranged with bevelled or roof-shaped bristle bundles, which are arranged at least partially rotated relative to one another according to the invention. Instead or in addition, however, groups of bundles of bristles with flat, rounded or sharpened areas of use could also be provided between groups of bristle bundles with slanted useful surfaces which are arranged rotated relative to one another.

Eine besondere Ausgestaltung der Erfindung könnte bei einer Zahnbürste mit auf einem äußeren Kreis angeordneten Borstenbündeln und im Inneren dieses Kreise angeordneten weitern Borstenbündeln, die besonders als elektrische Zahnbürste geeignet ist, dadurch gekennzeichnet sein, dass die auf dem äußeren Kreis und/oder in dessen Innerem angeordneten Borstenbündel an ihren freien Enden eine Schrägfläche haben und gegenüber dem Kreis, auf welchem sie angeordnet sind, zumindest teilweise um unterschiedliche Winkelbeträge verdreht angeordnet sind, so dass die Schrägflächen teils zur Mitte des Borstenfelds, teils nach außen, teils in Umfangsrichtung beziehungsweise in Zwischenstellungen dazu gewandt sind.A particular embodiment of the invention could be arranged in a toothbrush with bristle bundles arranged on an outer circle and further bristle bundles arranged in the interior of these circles, which is particularly suitable as an electric toothbrush, be characterized in that arranged on the outer circle and / or in its interior bristle bundles have at their free ends an inclined surface and relative to the circle on which they are arranged, at least partially rotated by different angular amounts are arranged so that the inclined surfaces are partly turned to the middle of the bristle field, partly to the outside, partly in the circumferential direction or in intermediate positions.

Bei derartigen runden Borstenfeldern, die an elektrischen Zahnbürsten oszillierende Teil-Drehbewegungen in jeweils abwechselnd entgegengesetzten Richtungen durchführen, ist es bekannt, insgesamt eine etwa muldenförmige Kontur des Borstenfeldes vorzusehen. Davon weicht die Erfindung mit den schon beschriebenen Effekten ab, indem bewusst gegenüber einer solchen regelmäßigen Kontur eine unregelmäßige Gesamtoberfläche des Borstenfeldes durch relativ zu entsprechenden Verbindungslinien, nämlich Kreisen unterschiedlich verdrehte Borstenbündel mit Schrägflächen vorgesehen werden, so dass deren Schrägflächen jeweils derartig abweichende Orientierungen haben, dass keine möglichst genau an eine Mulde angepasste Oberflächenkontur entsteht, obwohl die jeweiligen Borstenbündel eines solchen Borstenfeldes mit verschieden orientierten Schrägflächen unterschiedlich lang sein können. Somit kann auch mit einer derartigen oszillierenden Zahnbürste erreicht werden, dass der Benutzer je nach individueller Orientierung des Borstenfeldes innerhalb seines Mundes und an seinem Gebiss immer wieder günstig orientierte Borstenbündel mit Schrägflächen im Bereich der Interdentalzwischenräume ansetzen wird, ohne dies gezielt und mit erheblicher Geschicklichkeit anstreben zu müssen.In such round bristle fields, which perform on electric toothbrushes oscillating part-rotational movements in each case alternately opposite directions, it is known to provide an overall trough-shaped contour of the bristle field. The invention deviates therefrom with the effects already described by intentionally providing an irregular overall surface of the bristle field by means of bristle bundles with inclined surfaces that are twisted differently relative to corresponding connecting lines, namely circles, so that their oblique surfaces each have such different orientations that no surface contour which is adapted as precisely as possible to a depression is formed, although the respective bristle bundles of such a bristle field with differently oriented oblique surfaces may be of different lengths. Thus, even with such an oscillating toothbrush can be achieved that the user is always based on the individual orientation of the bristle field within his mouth and on his teeth low-priced oriented bristle bundles with inclined surfaces in the interdental spaces, without targeted and with considerable skill to strive for have to.

Dabei wird wie bei allen vorbeschriebenen Ausgestaltungen ausgenutzt, dass bei einem Borstenbündel mit schräger Nutzungsfläche dessen Oberfläche vergrößert ist und die einzelnen Borsten nicht nur mit ihren in der Regel gerundeten Stirnflächen, sondern auch noch mit Nachbarbereichen dieser Stirnflächen wirksam werden und auch die Zahnflächen gut erfassen können.It is exploited as in all embodiments described above, that in a bundle of bristles with oblique surface area of use is increased and the individual bristles not only with their generally rounded faces, but also with neighboring areas of these faces and effectively capture the tooth surfaces ,

Die mit Schrägflächen versehenen Borstenbündel des Borstenfeldes können dabei derart gegeneinander verdreht innerhalb des Borstenfeldes angeordnet sein, dass durch die jeweils nicht parallelen, sondern unterschiedlich orientierten Schrägflächen benachbarter oder in einer gemeinsamen Quer- oder Längsreihe des Borstenfeldes oder auch auf einem Kreis angeordneter Borstenbündel verlaufenden Ebenen einander schneiden und einen Winkelraum miteinander bilden.In this case, the bristle bundles of the bristle field provided with oblique surfaces can be arranged rotated within the bristle field in such a way that planes running through the respective non-parallel but differently oriented inclined surfaces of adjacent or in a common transverse or longitudinal row of the bristle field or on a circle arranged bristle bundles planes cut and form an angle space with each other.

In vielen Fällen sind die Borstenbündel der Borstenfelder von Zahnbürsten jeweils etwa gleich lang, so dass sich insgesamt eine gemeinsame Ebene an den Nutzungsenden der Borstenbündel ergibt. Daneben sind Profilierungen bekannt, durch die die Nutzungsenden der Borstenbündel unterschiedlich geformte Hüllflächen erzeugen. Auch die erfindungsgemäße Zahnbürste kann bei einer Ausgestaltung der Erfindung dadurch gekennzeichnet sein, dass die gegenüber dem Bürstenkörper überstehende Länge einzelner Borstenbündel etwa gleich und die anderer Borstenbündel verschieden groß ist. Es können also unterschiedlich lange Borstenbündel innerhalb des Borstenfeldes in geeigneter Weise kombiniert sein.In many cases, the bristle bundles of the bristle fields of toothbrushes are each about the same length, so that the overall result is a common plane at the ends of use of the bristle bundles. In addition, profilings are known by which the ends of use of the bristle bundles produce differently shaped enveloping surfaces. The toothbrush according to the invention may also be characterized in one embodiment of the invention in that the length of individual bundles of bristles protruding from the brush body is approximately the same and that of the other bundles of bristles is different. Thus, bristle bundles of different lengths can be combined in a suitable manner within the bristle field.

Die Schrägungswinkel der am Ende der Borstenbündel ausgebildeten Schrägflächen können gleich oder zumindest bei einzelnen Borstenbündeln gegenüber anderen Borstenbündeln unterschiedlich sein. Somit kann auch durch die Schrägungswinkel dafür gesorgt werden, dass einzelne Borstenbündel je nach Winkelstellung des Haltegriffs der Zahnbürste durch den Benutzer in optimaler Weise mit den Zähnen und den Zahnzwischenräumen in Berührung kommen und eine entsprechend gute Reinigungswirkung haben, wobei durch die Biegsamkeit der Borsten die Anpassung an die Interdentalzwischenräume in diesen und auch den vorbeschriebenen Fällen noch verbessert werden kann.The helix angles of the inclined surfaces formed at the end of the bundles of bristles may be the same or at least different for individual bristle bundles compared to other bundles of bristles. Thus, also by the helix angle be taken to ensure that individual bristle bundles depending on the angular position of the handle of the toothbrush by the user in an optimal manner with the teeth and the interdental spaces in contact and have a correspondingly good cleaning effect, with the flexibility of the bristles adaptation to the interdental spaces in these and Even the above cases can be improved.

Der Querschnitt der Borstenbündel kann etwa kreisförmig oder von einem Kreis abweichend sein. An sich sind Borstenbündel mit kreisrundem oder auch mit von einem Kreis abweichenden Querschnitten bekannt und die erfindungsgemäße Anordnung der Schrägflächen solcher Borstenbündel in jeweils relativ zueinander verdrehter Lage kann sowohl an runden als auch an in ihrem Querschnitt profilierten Borstenbündeln zur Anwendung kommen, wobei runde Borstenbündel den Vorteil haben, dass die gegenseitige verdrehte Anordnung unabhängig von den entsprechend runden Aufnahmeöffnungen im Bürstenkörper durchgeführt und eventuell auch sehr einfach in der Produktion verändert werden kann, weil die Aufnahmeöffnungen an den Bürstenkörpern nicht entsprechend angepasst werden müssen.The cross section of the bristle bundles may be approximately circular or deviating from a circle. In itself, bristle bundles with circular or even deviating from a circle cross sections are known and the inventive arrangement of the inclined surfaces of such bristle bundles in each relatively rotated position can be applied both round and profiled in their cross-section bristle bundles, round bristle bundles have the advantage have that the mutual twisted arrangement can be performed independently of the corresponding round receiving openings in the brush body and possibly also very easily changed in production, because the receiving openings on the brush bodies do not need to be adjusted accordingly.

Der Querschnitt wenigstens einzelner Borstenbündel kann vieleckig oder viereckig, insbesondere quadratisch sein und die am Nutzungsende einzelner derartiger Borstenbündel angeordneten Schrägflächen können ebenfalls vieleckig oder viereckig sein - was sich aus der Kontur der Borstenbündel entsprechend ergibt - wobei die Seiten der Vielecke oder Vierecke in der senkrechten Projektion der Borstenbündel übereinanderliegen oder gegeneinander derart verdreht sein können, dass die höchste Stelle der Schrägfläche kürzer als die Seitenlänge des Viel- oder Vierecks ist und insbesondere an einer Ecke des im Querschnitt viel- oder viereckigen Borstenbündel-Querschnitts angeordnet ist. Vor allem in einem solchen Falle, in dem die Schrägfläche relativ zum Querschnitt des Borstenbündels so orientiert ist, dass ihre höchste Stelle in einer Ecke des eckigen Querschnitts angeordnet ist, ergibt sich praktisch eine Spitze, gegenüber welcher die Schrägfläche und deren Begrenzungen schräg abfallen, so dass eine solche Spitze tief in Inderdentalzwischenräume eindringen kann, selbst wenn die Schrägfläche nicht genau zutreffend mit der benachbarten Zahnoberfläche übereinstimmt. Eine entsprechend gründliche Reinigung insbesondere auch im Bereich der Interdentalzwischenräume kann erzielt werden.The cross section of at least individual bundles of bristles may be polygonal or quadrangular, in particular square, and the inclined surfaces arranged at the end of use of such bundles of bristles may also be polygonal or quadrilateral - which results from the contour of the bundles of bristles - the sides of the polygons or quadrilaterals in the vertical projection the bristle bundles can be superimposed or rotated against each other such that the highest point of the inclined surface is shorter than the side of the polygon or quadrilateral and in particular at a corner of the im Cross-section square or square bristle bundle cross-section is arranged. Especially in such a case, in which the inclined surface is oriented relative to the cross section of the bristle bundle so that their highest point is located in a corner of the polygonal cross section, practically results in a tip, against which the inclined surface and its boundaries fall obliquely, so such a tip can penetrate deeply into interdental spaces, even if the bevel does not exactly coincide with the adjacent tooth surface. A correspondingly thorough cleaning, especially in the area of the interdental spaces, can be achieved.

Wenn vorstehend von Schrägflächen gesprochen wird, sind in der Regel ebene Schrägflächen gemeint, jedoch ist es auch möglich, dass die Schrägfläche(n) wenigstens eines Borstenbündels konvex oder konkav in einer oder in mehreren Richtungen gekrümmt ist (sind). Hat die schräge Nutzungsfläche also in sich eine beispielsweise konkave Krümmung, ist eine noch bessere Anpassung an die konvexe Wölbung einer Zahnfläche möglich. Darüber hinaus kann so der höchste Bereich der Schrägfläche entsprechend spitz und fein sein und besonders tief in einen Interdentalzwischenraum eindringen.When referring to oblique surfaces above, planar oblique surfaces are generally meant, but it is also possible that the oblique surface (s) of at least one bristle bundle is (are) curved convexly or concavely in one or more directions. If the inclined surface of use thus has a concave curvature, for example, an even better adaptation to the convex curvature of a tooth surface is possible. In addition, so the highest area of the inclined surface can be correspondingly pointed and fine and penetrate particularly deep into an interdental space.

Eine spezielle Anordnung kann vorsehen, dass nebeneinander angeordnete Borstenbündel gegenüber dem Bürstenkörper unterschiedlich weit hoch stehen oder unterschiedliche Längen haben, wobei insbesondere innerhalb einzelner Reihen gleichlange Borstenbündel angeordnet und die Schrägflächen der Borstenbündel einer solchen Reihe und/oder die einer benachbarten Reihe mit unterschiedlich langen Borstenbündeln teilweise gegeneinander verdreht angeordnet sein können. Es sind also nicht nur hinsichtlich der jeweiligen relativen Verdrehwinkel der einzelnen Borstenbündel um ihre Längsachsen, sondern auch hinsichtlich der Länge und auch der Schrägungswinkel der schrägen Nutzungsflächen unterschiedlichste gegenseitige Kombinationen möglich, um ein Borstenfeld zur Verfügung zu stellen, das bei unterschiedlichsten individuellen Anwendungen der Zahnbürste, sei sie von Hand oder elektrisch zu betreiben, die Wahrscheinlichkeit erhöht ist, dass die Zahnoberflächen, die Übergänge zu den Zahnzwischenräumen und schließlich auch die Zahnzwischenräume selbst während eines Putzvorganges möglichst häufig optimal beaufschlagt werden.A special arrangement may provide that juxtaposed bundles of bristles are at different heights relative to the brush body or have different lengths, in particular within equal rows arranged bristle bundles and the oblique surfaces of the bristle bundles of such a row and / or an adjacent row with bristles of different lengths partially can be arranged rotated against each other. So it's not just the relative relative angles of rotation of the individual Bristle bundles around their longitudinal axes, but also in terms of length and also the helix angle of the inclined surfaces use a variety of combinations possible to provide a bristle field available that increases the probability of a variety of individual applications of the toothbrush, be it manually or electrically operated is that the tooth surfaces, the transitions to the interdental spaces and finally also the interdental spaces are applied as often as possible even during a cleaning process as often as possible.

Vor allem bei Kombination einzelner oder mehrerer der vorbeschriebenen Merkmale und Maßnahmen ergibt sich eine Zahnbürste mit einem Borstenfeld, bei welchem der Benutzer nicht selbst versuchen muss, eine bestmögliche Orientierung des Borstenfeldes relativ zu seinem Gebiss zu finden, was schwierig ist, sondern bei welchem die Wahrscheinlichkeit erheblich gesteigert ist, dass bei unterschiedlichsten Winkelstellungen der Zahnbürste relativ zu dem Gebiss immer wieder bestimmte Borstenbündel in eine optimale Lage relativ zu den Zähnen und vor allem zu den Zahnzwischenräumen gelangen und eine entsprechend gute Reinigungswirkung haben.Especially when combining one or more of the features and measures described above results in a toothbrush with a bristle field, in which the user does not have to try himself to find the best possible orientation of the bristle field relative to his dentition, which is difficult, but where the probability is increased significantly that at different angular positions of the toothbrush relative to the teeth repeatedly certain bristle bundles get into an optimal position relative to the teeth and especially to the interdental spaces and have a correspondingly good cleaning effect.

Bei der nachfolgenden Beschreibung der verschiedenen Ausführungsbeispiele erhalten übereinstimmende Teile oder Gegenstände auch bei unterschiedlicher Gestaltung, aber übereinstimmender Funktion jeweils die selben Bezugszahlen.In the following description of the various embodiments, matching parts or objects are given the same reference numbers, even if the design is different but the function is the same.

Von einer Handzahnbürste ist dabei in den Fig. 1 und 2 jeweils ein im Ganzen mit 1 bezeichnetes Borstenfeld und der zugehörige Bürstenkörper 2, nicht aber der vollständige Hangriff 3, sondern nur ein Stück davon dargestellt.Of a manual toothbrush is shown in FIGS. 1 and 2, respectively, a designated as a whole with 1 bristle field and the associated brush body 2, but not the full hang handle 3, but only a part of it.

Die Fig. 3 bis 5 zeigen Bürstenkörper 2 mit kreisrunder Kontur und entsprechend runden Borstenfeldern 1, welche in elektrisch angetriebene Zahnbürsten einzusetzen sind.3 to 5 show brush body 2 with circular contour and correspondingly round bristle fields 1, which are to be used in electrically driven toothbrushes.

In allen Fig. sind also die wesentlichen Teile der jeweiligen Zahnbürste dargestellt, wobei entweder ein längliches oder ein rundes Borstenfeld 1 vorgesehen sein kann, welches aus einzelnen, nebeneinander an einem Bürstenkörper 2 angeordneten und gegenüber diesem hochstehenden Borstenbündeln 4 gebildet ist, die ihrerseits aus einzelnen Borsten bestehen.In all figures, therefore, the essential parts of the respective toothbrush are shown, wherein either an elongated or a round bristle field 1 may be provided which is formed of individual, juxtaposed on a brush body 2 and opposite this upstanding bristle bundles 4, which in turn consists of individual Bristles exist.

Dabei sind in den Ausführungsbeispielen gemäß Fig. 1, 3 und 5 alle Borstenbündel 4, in den Ausführungsbeispielen gemäß Fig. 2 und 4 in noch zu beschreibender Weise einzelne Borstenbündel 4 an dem dem Bürstenkörper 2 abgewandten Nutzungsende gegenüber einer etwa parallel zum Bürstenkörper 2 verlaufenden Ebene dadurch abgeschrägt, dass Borsten dieser Borstenbündel 4 unterschiedlich weit hoch stehen, so dass die am Nutzungsende dieser Borstenbündel 4 angeordneten Abschluss- oder Nutzungsflächen als Schrägflächen 5 oder auch als teilweise schräge Flächen ausgebildet sind.In the exemplary embodiments according to FIGS. 1, 3 and 5, all bristle bundles 4, in the exemplary embodiments according to FIGS. 2 and 4, in a manner to be described, separate bristle bundles 4 are opposite the end of use facing away from the brush body 2 an approximately parallel to the brush body 2 extending plane slanted characterized in that bristles of these bristle bundles 4 are different levels high, so that the end of use of these bundles of bristles 4 arranged termination or use surfaces are formed as inclined surfaces 5 or as partially inclined surfaces.

Beispielsweise ist im Zentrum der runden Borstenfelder 1 gemäß den Fig. 3 bis 5 jeweils ein zentrales Bortenbündel 4 dargestellt, bei welchem zwei im Winkel stehende Schrägflächen zu einer dachförmigen Form des Nutzungsendes 5 führen, was auch bei weiteren Borstenbündeln 4 der Fall sein könnte.For example, a central bundle bundle 4 is shown in the center of the round bristle fields 1 according to FIGS. 3 to 5, in which two angled inclined surfaces lead to a roof-shaped shape of the end of use 5, which could also be the case with further bristle bundles 4.

Die einzelnen Borstenbündel 4 sind entlang gedachter Verbindungslinien in Reihen angeordnet, wobei bei den Ausführungsformen gemäß Fig. 1 und 2 der Längsrand 6 des Bürstenkörpers 2 im Bereich des Borstenfeldes 1 eine solche etwas bogenförmige Verbindungslinie darstellt oder bildet, parallel zu welcher weitere gedachte Verbindungslinien in Längserstreckungsrichtung zwischen dort jeweils angeordneten Borstenbündeln 4 vorhanden sind. Ferner erkennt man deutlich quer zur Längserstreckungsrichtung verlaufende Reihen von Borstenbündeln, die also auf gedachten geraden Linien einander benachbart sind.The individual bristle bundles 4 are arranged along imaginary connecting lines in rows, wherein in the embodiments according to FIGS. 1 and 2, the longitudinal edge 6 of the brush body 2 in the region of the bristle field 1 represents or forms such a somewhat arcuate connecting line, parallel to which further imaginary connecting lines in the longitudinal direction of extension between each arranged bristle bundles 4 are present. Furthermore, one can clearly see rows of bundles of bristles running transversely to the direction of longitudinal extension, which are thus adjacent to one another on imaginary straight lines.

Die runden Borstenfelder 1 gemäß Fig. 3 zeigen deutlich gedachte kreisförmige Linien, insbesondere eine äußere Kreislinie auf welcher die äußeren Borstenbündel jeweils in einer Reihe angeordnet sind, die dann auch den äußeren Hüllkreis dieses Borstenfeldes 1 ergibt. Im Inneren eines solchen äußeren Kreises ist ein zweiter engerer Kreis vorhanden, auf welchem weitere Borstenbündel 4 angeordnet sind, wobei der äußere und dieser innere Kreis konzentrisch zueinander sind. Im gemeinsamen Zentrum befindet sich dann ein weiteres Borstenbündel 4, welches in den dargestellten Ausführungsbeispielen am Nutzungsende dachförmig abgeschrägt ist.The round bristle fields 1 according to FIG. 3 show clearly imaginary circular lines, in particular an outer circular line on which the outer bristle bundles are each arranged in a row, which then also results in the outer enveloping circle of this bristle field 1. Inside such an outer circle there is a second narrower circle on which further bristle bundles 4 are arranged, the outer and inner circles concentric with one another. In the common center is then another bundle of bristles 4, which is beveled roof-shaped in the illustrated embodiments at the end of use.

Beim Vergleich der einzelnen Borstenbündel 4 innerhalb des jeweiligen Borstenfelds 1 der verschiedenen Ausführungsbeispiele erkennt man, dass wenigstens einzelnen dieser Borstenbündel 4 mit ihren Schrägflächen 5 relativ zueinander und gegenüber den erwähnten und beschriebenen gedachten Verbindungslinien um unterschiedliche Winkel verdreht angeordnet sind, wobei diese Winkel von 90° und von 180° abweichen. Vor allem sind innerhalb des jeweiligen Borstenfelds 1 einander unmittelbar benachbarte Borstenbündel 4 mit ihren Schrägflächen 5 relativ zueinander verdreht angeordnet, das heißt die Schrägflächen 5 dieser Borstenbündel sind jeweils in einer etwas anderen Richtung orientiert, aber nicht einander entgegengesetzt und auch nicht rechtwinklig zueinander angeordnet. Legt man Durchmesserlinien jeweils durch die höchsten Stellen der Schrägflächen, sind also diese Durchmesserlinien relativ zueinander entsprechend verschwenkt angeordnet.When comparing the individual bristle bundles 4 within the respective bristle field 1 of the various embodiments, it can be seen that at least some of these bristle bundles 4 are arranged with their inclined surfaces 5 rotated relative to each other and opposite the mentioned and described imaginary connecting lines by different angles, said angle of 90 ° and deviate from 180 °. Above all, each other directly adjacent bristle bundles 4 are arranged with their inclined surfaces 5 rotated relative to each other within the respective bristle field 1, that is, the inclined surfaces 5 of these bristle bundles are each oriented in a slightly different direction, but not opposed to each other and not arranged at right angles to each other. If you put diameter lines respectively through the highest points of the inclined surfaces, so these diameter lines are arranged relative to each other pivoted accordingly.

Betrachtet man dabei Fig. 5, erkennt man, dass die auf dem äußeren Kreis des runden Borstenfelds 1 nebeneinander angeordneten Borstenbündel 4 gegenüber ihrer kreisförmigen Verbindungslinie nicht verdreht sondern gleich angeordnet sind, also gegenüber dem sie in Gedanken verbindenden Kreis alle die selbe Orientierung haben. Für diese äußeren Borstenbündel 4 und ihre Schrägflächen 5 des Ausführungsbeispiels nach Fig. 5 ist also das Merkmal der gegenseitigen verdrehten Anordnung bei gleichzeitig verdrehter Anordnung gegenüber der Verbindungslinie nicht erfüllt, wohl aber bei den im Inneren dieses äußeren Kreises befindlichen Borstenbündeln 4.Looking at FIG. 5, it can be seen that the bundles of bristles 4 juxtaposed on the outer circle of the round bristle field 1 are not rotated relative to their circular connecting line but are arranged the same, ie they all have the same orientation with respect to the circle connecting them in their thoughts. For these outer bristle bundles 4 and their oblique surfaces 5 of the embodiment of FIG. 5, therefore, the feature of the mutual twisted arrangement with the same twisted arrangement with respect to the connecting line is not met, but in the interior of this outer circle bristle bundles 4th

Vor allem bei der relativ großen Anzahl von Borstenbündeln 4 können auch einzelne, einander unmittelbar benachbarte oder aber durch zwischen ihnen befindliche Borstenbündel 4 beabstandeten Borstenbündel 4 mit ihren Schrägflächen 5 gegeneinander und/oder gegenüber einer gedachten Verbindungslinie doch um 90° oder auch um 180° gegeneinander verdreht angeordnet sein, wobei aber dann weitere Borstenbündel 4 des Borstenfeldes 1 um einen oder mehrere verschiedene, demgegenüber abweichende Winkel verdreht angeordnet sind. Es kann vor allem bei einer Vielzahl von Borstenbündeln 4 schon durch Zufall auftreten, dass durch die gegenseitige Verdrehte Anordnung auch Borstenbündel 4 mit ihrem Schrägflächen 5 um 90° oder um 180° gegeneinander verdreht angeordnet sind, wobei aber gleichzeitig weitere Borstenbündel 4 mit ihren Schrägflächen 5 um demgegenüber abweichende Winkelbeträge um ihre Längserstreckungsachse relativ zueinander verdreht befestigt sind.Especially in the relatively large number of bristle bundles 4 can also be individual, immediately adjacent or spaced by them bristle bundles 4 spaced bundles of bristles 4 with their inclined surfaces 5 against each other and / or against an imaginary connecting line but rotated by 90 ° or 180 ° against each other, but then more bristle bundles 4th of the bristle field 1 are arranged rotated by one or more different, contrasting angle. Especially with a large number of bristle bundles 4, it may happen by chance that bristle bundles 4 with their oblique surfaces 5 are also rotated by 90 ° or 180 ° relative to each other due to the mutual twisted arrangement, but at the same time further bristle bundles 4 with their oblique surfaces 5 In contrast, deviating angle amounts are fixed around their longitudinal axis of rotation relative to each other twisted.

In allen Fig. wird deutlich, dass die Schrägflächen 5 sehr verschieden orientiert sind, also viele Ebenen durch solche Schrägflächen 5 entstehen, die einander schneiden und Winkelräume bilden und also beim Ansetzen des Borstenfeldes 1 an ein Gebiss dieses in unterschiedlicher Weise und dabei auch so beaufschlagen, wie es zum Reinigen der Zahnflächen und der Interdentalzwischenräume besonders günstig ist.In all Fig. It is clear that the inclined surfaces 5 are oriented very different, so many levels arise through such inclined surfaces 5, which intersect and form angled spaces and thus applied when attaching the bristle field 1 to a denture this in a different manner and thereby so as it is particularly favorable for cleaning the tooth surfaces and the interdental spaces.

Während die Ausführungsbeispiele gemäß Fig. 1, 3 und 5 Borstenfelder 1 zeigen, bei denen alle Borstenbündel 4 an den Nutzungsflächen Schrägflächen 5 haben, die auch dachförmig ausgebildet sein können, zeigen die Fig. 2 und 4 Ausführungsbeispiele, bei welchen in dem Borstenfeld 1 mit Schrägflächen 5 oder schrägstehender Fläche versehene Borstenbündel 4 mit solchen kombiniert sind, deren Nutzungsflächen anders geformt sind. In beiden Ausführungsbeispielen sind dabei diese nicht mit Schrägflächen 5 versehenen Borstenbündel 4a an den Nutzungsenden gerundet, könnten aber auch angespitzt oder mit einer horizontalen ebenen Fläche oder in anderer beliebiger Form konturiert sein.While the embodiments of FIGS. 1, 3 and 5 show bristle fields 1, in which all bundles of bristles 4 on the use surfaces oblique surfaces 5, which may also be roof-shaped, Figs. 2 and 4 show embodiments in which in the bristle field 1 with Bevel surfaces 5 or inclined surface provided bristle bundles 4 are combined with those whose use surfaces are shaped differently. In both embodiments, these are not provided with inclined surfaces 5 bristle bundles 4a at the end of use rounded, but could also be sharpened or contoured with a horizontal flat surface or in any other shape.

Derartige Borstebündel 4a sind dabei innerhalb des Borstenfeldes 1 einander unmittelbar benachbart und gleichzeitig als Gruppen angeordnet, innerhalb welchen Gruppen gleiche oder ähnliche derartige Borstenbündel 4a zusammengefasst sind. Dies erkennt man besonders deutlich in Fig. 2, wobei beidseits einer Gruppe von Borstenbündeln 4 mit Schrägflächen 5 solche Borstenbündel 4a mit einer anders konturierten Nutzungsfläche vorgesehen sind. In diesem Falle ist also eine Gruppe von Borstenbündeln 4 mit Schrägflächen 5 als geschlossene Gruppe vorgesehen, obwohl auch Borstenbündel 4 mit Borstenbündeln 4a unregelmäßig gemischt sein könnten.Such bristle bundles 4a are in this case immediately adjacent to one another within the bristle field 1 and at the same time as groups, within which groups the same or similar such bristle bundles 4a are combined. This can be seen particularly clearly in Fig. 2, wherein on both sides of a group of bundles of bristles 4 with inclined surfaces 5 such bristle bundles 4a are provided with a different contoured area of use. In this case, therefore, a group of bundles of bristles 4 with inclined surfaces 5 is provided as a closed group, although bristle bundles 4 could also be mixed irregularly with bristle bundles 4a.

Beim Ausführungsbeispiel nach Fig. 4 ist eine innere Gruppe von Borstenbündeln 4 mit Schrägflächen 5 von einer weiteren Gruppe von Borstenbündeln 4a mit anders, nämlich gerundet konturierter Nutzungsfläche kombiniert, die auf einen Kreis außen um die Borstenbündel 4 mit Schrägflächen 5 angeordnet sind.In the embodiment according to FIG. 4, an inner group of bristle bundles 4 with inclined surfaces 5 is combined by another group of bristle bundles 4a having a different, namely rounded, contoured use surface, which are arranged on a circle outside around the bristle bundles 4 with inclined surfaces 5.

In dieser kombinierten Anordnung von unterschiedlichen Borstenbündeln 4 du 4a gemäß Fig. 2 und 4 sind aber die mit Schrägflächen 5 versehenen Borstenbündel 4 wiederum jeweils gegeneinander oder gegenüber einer gedachten Verbindungslinie um von 90° oder 180° abweichende Winkel verdreht zueinander angeordnet.In this combined arrangement of different bundles of bristles 4 du 4a shown in FIG. 2 and 4 but provided with inclined surfaces 5 bristle bundles 4 are in turn each against or against an imaginary connecting line by 90 ° or 180 ° different angle rotated to each other.

Bei dem länglichen Borstenfeld 1 gemäß Fig. 2 sind also die in Längsrichtung voneinander entfernten Bereiche dieses Borstenfeldes 1 mit Borstenbündeln 4a versehen, deren Nutzungsenden gerundet sind, aber auch eine andere Kontur haben könnten, und dazwischen befindet sich eine Gruppe von Borstenbündeln 4 mit abgeschrägter oder auch dachförmiger Nutzungsfläche.In the elongated bristle field 1 according to FIG. 2, therefore, the regions of this bristle field 1 which are separated from one another in the longitudinal direction are provided with bundles of bristles 4a whose ends of use are rounded but could also have a different contour, and a group of bristle bundles 4 is therebetween beveled or roof-shaped use area.

In Fig. 4, sind, wie schon erläutert, auf dem äußeren Kreis dieses runden Borstenfeldes 1 Borstenbündel 4a mit abgerundeter Nutzungsfläche und im Inneren des Kreises solche mit Schrägflächen angeordnet, wobei diese wiederum um unterschiedliche Winkelbeträge verdreht orientiert sind. Die Schrägflächen 5 sind dabei teils zur Mitte des Borstenfeldes 1, teils nach außen, teils in Umfangsrichtung beziehungsweise auch in Zwischenstellungen dazu gewandt, was auch für die inneren Borstenbündel innerhalb des äußeren Kreises gemäß Fig. 5 zutrifft.In Fig. 4, as already explained, arranged on the outer circle of this round bristle field 1 bristle bundles 4a with rounded use surface and inside the circle with inclined surfaces, which in turn are rotated by different angular amounts oriented. The inclined surfaces 5 are partly to the center of the bristle field 1, partly outwardly, partly in the circumferential direction or in intermediate positions turned to what is true for the inner bristle bundles within the outer circle of FIG. 5.

Es sei erwähnt, dass aber auch Borstenbündel 4 mit Schrägflächen 5 und Borstenbündel 4a miteinander vermischt sein könnten.It should be noted, however, that bristle bundles 4 with oblique surfaces 5 and bristle bundles 4a could also be mixed with one another.

Fig. 5 könnte als Sonderfall des Ausführungsbeispiels nach Fig. 4 angesehen werden, weil dabei auf dem äußeren Kreis angeordnete Borstenbündel 4 mit Schrägflächen 5 versehen sind, die aber gegenüber dem Verbindungskreis nicht unterschiedlich verdreht, sondern alle radial zur Mitte hin orientiert sind. Dadurch ergeben sich aber zusammen mit den Borstenbündeln 4 innerhalb dieses Kreises wiederum zahlreiche Konstellationen zwischen einzelnen Borstenbündeln, deren Schrägflächen relativ zueinander um von 90° und von 180° abweichende Winkel relativ zueinander um ihr rechtwinklig zum Bürstenkörper 2 orientierten Längsachsen verdreht sind.Fig. 5 could be regarded as a special case of the embodiment of FIG. 4, because in this case arranged on the outer circle bristle bundles 4 are provided with inclined surfaces 5, but not twisted differently from the connection circle, but are all oriented radially towards the center. This, however, together with the bundles of bristles 4 within this circle turn numerous constellations between individual bristle bundles, the inclined surfaces are rotated relative to each other by 90 ° and 180 ° deviating angle relative to each other at right angles to the brush body 2 oriented longitudinal axes.

In allen Ausführungsbeispielen ist vorgesehen, dass der Querschnitt der Borstenbündel 4 und 4a etwa kreisförmig und gleich ist, jedoch könnte dieser Querschnitt auch von einem Kreis abweichen und beispielsweise vieleckig oder viereckig, insbesondere quadratisch sein, wodurch sich in Kombination mit Schrägflächen unterschiedliche zusätzliche Effekte erzielen lassen.In all embodiments, it is provided that the cross section of the bristle bundles 4 and 4a is approximately circular and equal, but this cross section could also differ from a circle and be polygonal or quadrangular, in particular square, for example, which can be used in combination with inclined surfaces to achieve different additional effects ,

Im Querschnitt runde Borstenbündel 4 und 4a erleichtern jedoch die Bestückung eines entsprechende Aufnahmeöffnungen aufweisenden Bürstenkörpers 2, da die Aufnahmeöffnungen in allen Fällen gleich bleiben unabhängig davon, ob und um welchen Winkelbetrag die zugehörigen Borstenbündel relativ zueinander beziehungsweise zu Verbindungslinien und damit auch zum Bürstenkörper 2 verdreht eingesetzt werden.Cross-section round bristle bundles 4 and 4a, however, facilitate the placement of a corresponding receiving openings having brush body 2, since the receiving openings remain the same regardless of whether and at what angle the associated bristle bundles relative to each other or to connecting lines and thus also used to the brush body 2 twisted become.

Es sei außerdem erwähnt, dass in allen Ausführungsbeispielen die Borstenbündel 4 und 4a der Borstenfelder 1 eine übereinstimmende Länge haben, also gegenüber dem Bürstenkörper 2 um einen übereinstimmenden Betrag überstehen.It should also be mentioned that in all embodiments, the bristle bundles 4 and 4a of the bristle fields 1 have a matching length, so over the brush body 2 survive by a matching amount.

Es wäre aber auch möglich, davon abzuweichen und Borstenbündel 4 und 4a unterschiedlicher Länge in geeigneter Weise zu kombinieren.However, it would also be possible to deviate from this and to combine bristle bundles 4 and 4a of different lengths in a suitable manner.

Ferner könnte abweichend von den Ausführungsbeispielen vorgesehen sein, dass einzelne oder alle Schrägflächen 5 der verschiedenen Borstenbündel 4 statt der in den Ausführungsbeispielen gezeigten ebenen Form konvex oder konkav in einer oder mehreren Richtungen gekrümmt sein könnten. Die Schrägflächen 5 könnten also ballig oder muldenförmig oder auch Teile von Zylindern oder Hohlzylindern sein, wobei dies bezüglich der einzelnen Borstenbündel 4 des Borstenfeldes 1 auch wechseln könnte.Furthermore, it could be deviating from the exemplary embodiments that individual or all oblique surfaces 5 of the different bristle bundles 4 could be curved convexly or concavely in one or more directions instead of the planar shape shown in the exemplary embodiments. The inclined surfaces 5 could thus be spherical or trough-shaped or even parts of cylinders or hollow cylinders, and this could also change with respect to the individual bristle bundles 4 of the bristle field 1.

Bei Betrachtung der Borstenfelder 1 gemäß den Ausführungsbeispielen und vor allem bei denen gemäß Fig. 1, 3 und 5 wird deutlich, dass durch die relative Unregelmäßigkeit der gegenseitigen Anordnung der Schrägflächen 5 beziehungsweise der unterschiedlichen Winkel, die die durch sie verlaufenden Ebenen im Raum einnehmen, entsprechend viele Möglichkeiten und somit eine hohe Wahrscheinlichkeit besteht, dass eine solche Schrägfläche 5 mit ihrem höherstehenden Rand in einen Interdentalzwischenraum eindringt unabhängig davon, wie genau ein Benutzer die Zahnbürste mit dem entsprechende Borstenfeld 1 in den Mund einführt und darin bewegt. Gegenüber regelmäßig vorgegebenen Konturierungen von Borstenfeldern, die eine entsprechend präzise Bewegungsrichtung gegenüber den einzelnen Zähnen erfordern, um eventuell in der gewünschten Weise wirksam zu werden, ist also der Benutzer frei in der Art, wie und vor allem unter welchem Winkel er den Handgriff einer elektrischen oder einer handbetätigten Zahnbürste erfasst und eventuell auch während des Putzvorganges - bevorzugt auf und ab - bewegt und eventuell verändert. Im Verlaufe eines solchen Zahnputzvorganges entlang den Zahnreihen werden immer wieder Borstenbündel mit ihren Schrägflächen in eine günstige Lage relativ zu den Zähnen und den Zahnzwischenräumen gelangen und können dann entsprechend tief in diese eindringen und eine gründliche Reinigungswirkung entfalten.When viewing the bristle fields 1 according to the embodiments and especially in those according to FIGS. 1, 3 and 5, it is clear that the relative irregularity of the mutual arrangement of the inclined surfaces 5 or the different angles which occupy the planes passing through them in space, accordingly many possibilities and thus there is a high probability that such an inclined surface 5 penetrates with its raised edge in an interdental space regardless of how exactly a user introduces the toothbrush with the corresponding bristle field 1 in the mouth and moves therein. Compared with regularly given contouring of bristle fields that require a correspondingly precise direction of movement relative to the individual teeth to possibly be effective in the desired manner, so the user is free in the way and especially at what angle he the handle of an electric or a hand-operated toothbrush detected and possibly during the cleaning process - preferably up and down - moves and possibly changed. In the course of such Zahnputzvorganges along the rows of teeth bristle bundles are always pass with their inclined surfaces in a favorable position relative to the teeth and the interdental spaces and can then penetrate correspondingly deep into this and develop a thorough cleaning effect.

Die Zahnbürste kann insbesondere als Handzahnbürste ein längliches Borstenfeld 1 und als elektrisch angetriebene Zahnbürste ein rundes Borstenfeld 1 haben, welches aus einzelnen, nebeneinander an einem Bürstenkörper 2 angeordneten und gegenüber diesem im Wesentlichen rechtwinklig hochstehenden Borstebündeln 4 gebildet ist. Wenigstens einzelne Borstenbündel 4 sind dabei an den dem Bürstenkörper 2 abgewandten Nutzungsende gegenüber einer etwa parallel zum Bürstenkörper 2 verlaufenden Ebene zumindest teilweise dadurch abgeschrägt oder dachförmig geformt, dass Borsten dieser Borstenbündel 4 unterschiedlich weit hoch stehen, so dass die am Nutzungsende dieser Borstenbündel 4 angeordneten Abschlussflächen als Schrägflächen 5 oder als teilweise schräge Flächen ausgebildet sind, wobei diese Borstenbündel 4 entlang gedachter gerader oder bogenförmiger oder bei Rundbürsten kreisbogen- oder kreisförmiger Verbindungslinien am Bürstenkörper 2 einander benachbart in Reihe angeordnet sind. Wenigstens einzelne, insbesondere größere Gruppen oder auch alle Borstenbündel 4 dieses Borstenfeldes 1 sind dabei mit ihren Schrägflächen 5 relativ zueinander und gegenüber den Verbindungslinien um unterschiedliche Winkel verdreht angeordnet, so dass eine Vielzahl von unterschiedlich orientierten Schrägflächen beim Putzen der Zähne zur Verfügung stehen und die Wahrscheinlichkeit groß ist, dass eine solche Schrägfläche in günstiger Orientierung vor allem in einen Zahnzwischenraum eingreift und diesen gründlich reinigt.In particular, the toothbrush can have an elongated bristle field 1 as a manual toothbrush and a round bristle field 1 as an electrically driven toothbrush, which is formed from individual bristle bundles 4 arranged side by side on a brush body 2 and projecting at right angles thereto. At least individual bristle bundles 4 are at the end facing away from the brush body 2 at least partially beveled by a plane extending approximately parallel to the brush body 2 by or roof-shaped that bristles of these bristle bundles 4 are different high, so that the end of use of these bristle bundles 4 arranged end surfaces are formed as inclined surfaces 5 or as partially inclined surfaces, said bristle bundles 4 along imaginary straight or arcuate or at Circular brushes circular or circular connecting lines on the brush body 2 adjacent to each other are arranged in series. At least individual, in particular larger groups or all bristle bundles 4 of this bristle field 1 are arranged with their inclined surfaces 5 relative to each other and against the connecting lines twisted at different angles, so that a variety of differently oriented inclined surfaces when brushing the teeth are available and the probability it is great that such an inclined surface engages in a favorable orientation especially in a tooth space and cleans it thoroughly.
