Description
Die Erfindung betrifft eine Zahnbürste mit einem auswechselbaren, in einer länglichen Halteaussparung eines mit einem Stiel und einem Griffstück verbundenen Kopfteils einrastbaren Borsteneinsatz und einem mit dem Borsteneinsatz verbundenen Drückerknopf, der durch eine nahe dem griffseitigen Ende der Halteaussparung angeordneten Öffnung der Rückwand der Halteaussparung ragt, wobei beiderseits des Drückerknopfes und stirnseitig an dem dem Drückerknopf abgekehrten Ende des Borsteneinsatzes an dessen Umfangsfläche jeweils Rastleisten vorspringen, die in Rastnuten an der Innenwand der Halteaussparung eingreifen, die nur im Bereich der Rastleisten an der Innenwand der Halteaussparung angeordnet sind.The invention relates to a toothbrush with a interchangeable, in an elongated recess head part connected with a handle and a handle snap-in bristle insert and one with the Bristle insert connected push button, which is activated by a near the handle-side end of the holding recess arranged opening of the rear wall of the retaining recess protrudes, being on both sides of the pusher button and the front at the end of the Bristle insert on the circumferential surface of each Protruding ledges project into locking grooves on the inner wall the holding recess intervene that only in Area of the locking strips on the inner wall of the Retaining recess are arranged.
Derartige, auch als Wechselkopf-Zahnbürsten bezeichnete Zahnbürsten sind in zahlreichen Ausführungsformen bekannt. Ihnen ist gemeinsam, daß der Borsteneinsatz auswechselbar ist, wobei die Verbindung zwischen dem Borsteneinsatz und dem Kopfteil durch eine Rastverbindung erfolgt. Zum einen soll der Borsteneinsatz bei der Benutzung der Zahnbürste fest im Kopfteil verankert sein, so daß er sich nicht unbeabsichtigt lösen kann. Zum anderen soll die Rastverbindung aber so leicht lösbar sein, daß der Borsteneinsatz in einfacher Weise und ohne Verwendung eines Werkzeugs ausgewechselt werden kann. Such, also referred to as interchangeable toothbrushes Toothbrushes are known in numerous embodiments. They have in common that the bristle insert is interchangeable is, the connection between the bristle insert and the headboard is done by a snap connection. On the one hand the bristle insert should be used when using the toothbrush be firmly anchored in the headboard so that it does not move can unintentionally solve. On the other hand, the Snap connection but so easy to release that the Bristle insert in a simple manner and without use of a tool can be replaced.
Bei einer bekannten Zahnbürste (DE-GM 91 09 625) ist der Borsteneinsatz so gestaltet, daß seine Seitenwände in Richtung der Borsten konvergieren. Diese Seitenwände und die jeweils zugeordneten Innenwände der Halteaussparung sind eben und frei von Nuten ausgeführt. Die von Rastleisten bzw. Rastvorsprüngen und zugeordneten Rastnuten gebildeten Rastverbindungen sind jeweils an den beiden Enden des Borsteneinsatzes vorgesehen. Da diese Rastverbindung an beiden Enden des Borsteneinsatzes nahe an dessen borstenseitiger Außenfläche angreift, besteht bei einer Durchbiegung des Kopfteils die Gefahr, daß die Rastverbindung an einem Ende des Borsteneinsatzes ausklinkt und sich der Borsteneinsatz vom Kopfteil löst. Um dies zu vermeiden, muß insbesondere an der griffseitigen Rastverbindung eine verhältnismäßig große Hinterschneidung vorgesehen sein, um einen formschlüssigen Halteeingriff zu gewährleisten. Dies hat andererseits aber zur Folge, daß zum Lösen des Borsteneinsatzes eine verhältnismäßig starke Verformung und damit große Kraft erforderlich ist.In a known toothbrush (DE-GM 91 09 625) Bristle insert designed so that its side walls in Converge towards the bristles. These sidewalls and the respective assigned inner walls of the holding recess are flat and free of grooves. The of Locking strips or locking projections and assigned Locking grooves formed locking connections are in each case on the provided at both ends of the bristle insert. This one Snap connection at both ends of the bristle insert close attacks on its bristle-side outer surface with a deflection of the head part, the risk that the Snap connection at one end of the bristle insert unlatches and the bristle insert detaches from the head part. To avoid this, the handle-side locking connection a relatively large Undercut can be provided to form a positive To ensure hold engagement. On the other hand, this has with the result that a to loosen the bristle insert relatively strong deformation and therefore great force is required.
Bei einer anderen bekannten Zahnbürste (DE-OS 30 38 895) sind die Rastleisten an den zueinander parallelen Seitenflächen des Borsteneinsatzes im Abstand zueinander angeordnet. Da die Umfangsfläche des Borsteneinsatzes am gesamten Umfang senkrecht zur borstenseitigen Grundfläche des Borsteneinsatzes verläuft, erfolgt die Verbindung zwischen dem Borsteneinsatz und dem Kopfteil ohne Klemmwirkung nur durch die an den Rastleisten aufgebrachten Rastkräfte.In another known toothbrush (DE-OS 30 38 895) are the locking bars on the parallel to each other Side surfaces of the bristle insert at a distance from each other arranged. Since the peripheral surface of the bristle insert on entire circumference perpendicular to the base surface on the bristle side of the bristle insert, the connection is made between the bristle insert and the headboard without Clamping effect only by the on the locking bars applied locking forces.
Auch bei einer Zahnbürste der eingangs genannten Gattung (DE-PS 37 24 640) verläuft die Umfangsfläche des Borsteneinsatzes senkrecht zur borstenseitigen Grundfläche des Borsteneinsatzes, und die Verankerung des Borsteneinsatzes erfolgt ausschließlich durch die Halteleisten, die sich hierbei über einen wesentlichen Teil der Länge der zueinander parallelen Seitenflächen des Borsteneinsatzes erstrecken. Die die Rastleisten aufnehmende Rastnut erstreckt sich über den gesamten inneren Umfang der Halteaussparung wodurch die Berührungsfläche zwischen der Umfangsfläche des Borsteneinsatzes und der Halteaussparung weiter verringert wird.Even with a toothbrush of the type mentioned at the beginning (DE-PS 37 24 640) runs the peripheral surface of the Bristle insert perpendicular to the base on the bristle side of the bristle insert, and the anchoring of the Bristle use is made exclusively by Retaining strips, which cover an essential part the length of the parallel side surfaces of the Extend bristle insert. The locking bars receiving locking groove extends over the entire inner circumference of the holding recess whereby the Contact surface between the peripheral surface of the Bristle insert and the holding recess further reduced becomes.
Aufgabe der Erfindung ist es daher, eine Zahnbürste der eingangs genannten Gattung zu schaffen, bei der die Vorteile einer leichten Lösbarkeit des Borsteneinsatzes mit den Vorteilen einer im Betrieb sicheren und spielfreien Verbindung zwischen Borsteneinsatz und Kopfteil verbunden werden.The object of the invention is therefore a toothbrush to create the type mentioned, in which the Advantages of an easy detachability of the bristle insert with the advantages of a safe and reliable operation backlash-free connection between bristle insert and Headboard to be connected.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß sich der Borsteneinsatz über den größten Teil seiner Länge zu dem dem Drückerknopf abgekehrten Ende verjüngt und in dem sich verjüngenden Bereich mit glatten, ununterbrochenen Abschnitten seiner Umfangsfläche flächig an glatten, ununterbrochenen Abschnitten der Innenwand der Halteaussparung anliegt.This object is achieved in that the bristle insert extends over most of its length tapered to the end facing away from the push button and in the tapered area with smooth, uninterrupted portions of its peripheral surface on smooth, uninterrupted sections of the inner wall of the Retaining recess is present.
Durch die sich zum kopfseitigen Ende hin verjüngende Grundrißgestalt des Borsteneinsatzes und der Halteaussparung wird eine Keil- oder Klemmwirkung erreicht, durch die der Borsteneinsatz sicher im Kopfteil gehalten wird. Diese Klemmwirkung tritt an verhältnismäßig großen, ununterbrochenen Flächenbereichen der Umfangsfläche des Borsteneinsatzes ein, so daß dieser auch bei einer Verformung des Kopfteils bei der Benutzung noch sicher gehalten wird. Due to the tapering towards the head end Floor plan of the bristle insert and Retaining recess becomes a wedge or clamping effect reached, through which the bristle insert securely in the head part is held. This clamping effect occurs proportionately large, uninterrupted areas of the Circumferential surface of the bristle insert, so that it too if the head section is deformed when still in use is kept safe.
Vorzugsweise verlaufen die Umfangsfläche des Borsteneinsatzes und die Innenwand der Halteaussparung im wesentlichen senkrecht zur borstenseitigen Grundfläche des Borsteneinsatzes. Deshalb tritt die den Borsteneinsatz abstützende Keilwirkung nur in Längsrichtung des Borsteneinsatzes auf; das Lösen des Borsteneinsatzes wird dadurch nicht beeinträchtigt, zumal sich der Drückerknopf in demjenigen Bereich des Borsteneinsatzes befindet, in dem die Haltewirkung im wesentlichen nur durch die beiderseitigen Rastleisten verursacht wird.Preferably, the peripheral surface of the Bristle insert and the inner wall of the holding recess in the substantially perpendicular to the bristle-side base of the Bristle insert. Therefore, the bristle insert occurs supporting wedge effect only in the longitudinal direction of the Bristle insert on; loosening the bristle insert will not affected, especially since the push button located in that area of the bristle insert in which the holding effect essentially only by the mutual locking bars is caused.
Gemäß einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, daß sich der Borsteneinsatz mit seinem Drückerknopf am griffseitigen Ende der Öffnung der Rückwand abstützt. Dadurch wird der Borsteneinsatz in seiner Längsrichtung elastisch eingespannt, wobei die Abstützung einerseits am Drückerknopf und andererseits an den sich keilförmig verjüngenden Seitenflächen erfolgt. Da diese beiden Abstützbereiche in ausreichend großem Abstand zueinander liegen, wirkt sich die elastische Federung des dazwischen befindlichen Materials günstig auf die Verankerungswirkung aus. Mit anderen Worten der Borsteneinsatz wird von seinem den Drückerknopf aufweisenden Ende her in die Keilverbindung mit dem Kopfteil gedrückt. Die flächige, nicht durch Leisten oder Nuten unterbrochene Berührung zwischen dem Bürstenkopf und dem Kopfteil in dem sich verjüngenden Abschnitt bewirkt eine sichere Abstützung und Verbindung.According to a preferred embodiment of the invention provided that the bristle insert with his Push button at the handle end of the opening of the Supports the rear wall. This will make the bristle insert in its longitudinal direction clamped elastically, the Support on the one hand on the push button and on the other hand the tapered side surfaces. There these two support areas at a sufficiently large distance lie to each other, the elastic suspension of the material in between on the cheap Anchoring effect. In other words the Bristle insert is from his the push button having end in the wedge connection with the Headboard pressed. The flat, not by strips or Grooves interrupted contact between the brush head and the head part in the tapered section secure support and connection.
Gemäß einer vorteilhaften Ausführungsform der Verbindung ist vorgesehen, daß der Borsteneinsatz im Grundriß einen halbkreisförmigen Abschnitt mit größerem Radius an seinem griffseitigen Ende aufweist, von dem im wesentlichen geradlinige Umfangsabschnitte zu einem halbkreisförmigem Abschnitt mit kleinerem Radius am entgegengesetzten Ende konvergieren. According to an advantageous embodiment of the connection it is provided that the bristle insert in the floor plan semicircular section with a larger radius at its has handle-side end, of which essentially rectilinear peripheral sections to a semicircular Smaller radius section at the opposite end converge.
Nachfolgend wird ein Ausführungsbeispiel der Erfindung
näher erläutert, das in der Zeichnung dargestellt ist.
Es zeigt:
Die in Fig. 1 gezeigte Zahnbürste weist ein Hauptteil 1
auf, das einstückig aus Kunststoff geformt ist und ein
Griffstück 2, einen Stiel 3 und eine Kopfteil 4 aufweist.
Im Kopfteil 4 ist ein Borsteneinsatz 5 auswechselbar
aufgenommen, der Borsten 6 trägt. Der Borsteneinsatz 5 ist
in eine Halteaussparung 7 des Kopfteils 4 einrastend
eingesetzt.The toothbrush shown in FIG. 1 has a
Wie man in Einzelheiten in den Fig. 3-5 erkennt, ist der
dort mit nur angedeuteten Borsten 6 dargestellte
Borsteneinsatz 5 länglich ausgeführt und erstreckt sich
von einem breiteren, griffseitigen Ende 8 zu einem
schmaleren, entgegengesetzten Ende 9.3-5, is the
shown there with only indicated
Der aus Kunststoff bestehende Borsteneinsatz 5 ist an
seiner Rückseite mit einem Drückerknopf 10 versehen, der im
eingesetzten Zustand durch eine Öffnung 11 in der Rückwand
12 des Kopfteils 4 ragt. Der Drückerknopf 10 und die
zugeordnete Öffnung 11 sind gegenüber der Längsmitte der
Halteaussparung 7 versetzt und sind nahe dem griffseitigen
Ende der Halteaussparung 7 angeordnet.The
Aus der Umfangsfläche 13 des Borsteneinsatzes 5, die ebenso
wie die zugeordnete Innenwand 14 der Halteaussparung 7 im
wesentlichen senkrecht zur borstenseitigen Grundfläche 15
des Borsteneinsatzes 5 verläuft, springen beiderseits des
Drückerknopfes 10 Rastleisten 16 vor, die in
gegenüberliegende Rastnuten 17 der Innenwand 14 der
Rastaussparung 7 eingreifen Eine stirnseitige Rastleiste
18 an dem dem Drückerknopf 10 abgekehrten Ende des
Borsteneinsatzes 5 greift in eine dort in der Innenwand 14
der Halteaussparung 7 vorgesehene Rastnut 19.From the
Wie man besonders deutlich aus Fig. 4 erkennt, verjüngt
sich der Borsteneinsatz 5 - im Grundriß gesehen - über den
größten Teil seiner Länge zu dem dem Drückerknopf 10
abgekehrten Ende 9. In dem sich verjüngenden Bereich 20
liegt die Umfangsfläche 13 des Borsteneinsatzes 5 flächig,
d.h. mit einer glatten, ununterbrochenen Fläche an einem
ebenfalls glatten, ununterbrochenen Abschnitt 21 der
Halteaussparung 7 an. Dieser Abschnitt 21 ist auch nicht
durch Rastnuten unterbrochen.As can be seen particularly clearly from FIG. 4, tapered
the bristle insert 5 - seen in plan - over the
most of its length to that of the
Im eingesetzten Zustand ragt der Drückernopf 10 mit seiner
vorzugsweise gewölbten Oberfläche 22 über die Außenseite
des Kopfteils 4 hinaus, wie man aus Fig. 1 erkennt, so daß
der Borsteneinsatz 5 durch einen verhältnismäßig leichten
Druck auf die gewölbte Außenfläche 22 des Drückerknopfes
10 gelöst werden kann. Gleichwohl ist der Borsteneinsatz 5
im eingesetzten Zustand durch die zwischen den Flächen 20
und 21 auftretende Keil- bzw. Klemmwirkung sicher im
Kopfteil 4 gehalten. Stattdessen kann der Drückerknopf
auch so ausgeführt sein, daß er bündig mit der Außenseite
des Kopfteils abschließt oder insgesamt über diese
vorsteht.In the inserted state, the button knob 10 projects with its

Vorzugsweise sind die Abmessungen des Borsteneinsatzes 5
und des Kopfteils 4 so gewählt, daß sich der Borsteneinsatz
5 mit seinem Drückerknopf 10 am griffseitigen Ende 11a
der Öffnung 11 der Rückwand 12 abstützt, so daß der
Borsteneinsatz 5 von dort her in den Keil-Klemmsitz
zwischen den Flächen 20 und 21 gedrückt wird. Die hierfür
erforderliche Längsverschiebung des Borsteneinsatzes 5
beeinträchtigt die Rastwirkung zwischen den Rastleisten
16, 18 und den jeweils zugeordneten Rastnuten 17 bzw. 19
nicht. Wie man aus Fig. 4 erkennt, weist der
Borsteneinsatz 5 im Grundriß vorzugsweise einen
halbkreisförmigen Abschnitt mit größerem Radius an seinem
griffseitigen Ende 8 auf. Von diesem Abschnitt verlaufen
im wesentlichen geradlinige Umfangsabschnitte
konvergierend zu einem halbkreisförmigem Abschnitt mit
kleinerem Radius am entgegengesetzten Ende 9. Abweichend
hiervon kann auch eine andere, sich zum einen Ende hin
verjüngende Grundrißform gewählt werden.The dimensions of the
