Zahnbürste BeschreibungToothbrush description
Die Erfindung betrifft eine Zahnbürste mit einem aus einer Platte mit einseitig darin angeordneten Borstenbündeln bestehenden Bürstenkopf und einem mit einem Ende der Platte verbundenen Griffteil nach dem Oberbegriff des Anspruchs 1.The invention relates to a toothbrush with a brush head consisting of a plate with bundles of bristles arranged therein on one side and a handle part connected to one end of the plate according to the preamble of claim 1.
Es ist eine Vielzahl von derartigen Zahnbürsten bekannt, wobei in aller Regel der Bürstenkopf gerade oder unter einem Wi kel fest mit dem Griff, der ebenfalls gewinkelt sein kann, verbunden ist.There are a variety of such toothbrushes known, as a rule, the brush head straight or under a Wi angle with the handle, which can also be angled, connected.
Es erscheint wünschenswert, den vorgegebenen Winkel zwischen Bürsten¬ kopf und Griffteil verändern zu können, um eine parallele Ausrichtung des Bürstenkopfes zu dem jeweils auf einem mehr oder weniger halb¬ kreisförmigen Bogen angeordneten Zähnen, insbesondere im hinteren Be¬ reich des Gebisses, erreichen zu können.It seems desirable to be able to change the predetermined angle between the brush head and the handle part in order to be able to achieve a parallel alignment of the brush head with the teeth arranged on a more or less semicircular arc, particularly in the rear area of the bit .
Aufgabe der Erfindung ist es daher, eine Zahnbürste zu konstruieren, die es ermöglicht, während der Benutzung auf einfache Weise den Winkel zwischen Bürstenkopf und Griffteil zu verändern.The object of the invention is therefore to construct a toothbrush which enables the angle between the brush head and the handle part to be changed in a simple manner during use.
Diese Aufgabe wird durch eine Zahnbürste mit den Merkmalen des An¬ spruchs 1 gelöst.This object is achieved by a toothbrush with the features of claim 1.
Vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen zu entnehmen.Advantageous embodiments of the invention can be found in the subclaims.

Aus der DE-A 554 155 ist bereits eine Zahnbürste mit einem verstell¬ baren Bürεtenkörper bekannt, dessen Winkel durch eine bewegliche Stielhälfte in der Weise einstellbar ist, daß die eine Hälfte des Stieles mit einem Z.ahn versehen ist, der in entsprechende Lücken der anderen Stielhälfte derart eingreift, daß der Bürstenkörper in mehreren Schwenkstellungen unverrrückbar zum Handgriff gehalten wird. Diese Anordnung gestattet nur eine unveränderliche Einstellung des Bürstenkörpers, während erfindungsgemäß eine flexible Verstellbarkeit des Bürstenkörpers während des Zähneputzens gefordert und gewähr¬ leistet ist.From DE-A 554 155 a toothbrush with an adjustable brush body is already known, the angle of which can be adjusted by means of a movable half of the handle in such a way that one half of the handle is provided with a tooth which fits into corresponding gaps engages the other half of the handle in such a way that the brush body is held immovably to the handle in several pivot positions. This arrangement allows only an unchangeable adjustment of the brush body, while according to the invention a flexible adjustability of the brush body during brushing is required and guaranteed.
Ebenfalls unterschiedlich hinsichtlich Aufgabenstellung und -lösung ist die aus der DE-A 283 892 bekannte Zahnbürste, die eine Verstellbarkeit des Borstenkörpers durch eine in einem Hohlraum des Stieles angeordnete Spindel zum Gegenstand hat und damit in keinem näheren Zusammenhang zur erfindungsgemäßen Ausgestaltung steht.The toothbrush known from DE-A 283 892 is also different with regard to the task and solution, and has as its object the adjustability of the bristle body by means of a spindle arranged in a cavity of the stem, and is therefore in no way related to the configuration according to the invention.
Nachstehend soll die Erfindung anhand von Ausführungsbeispielen unter Bezug auf schematische Zeichnungen näher erläutert werden. Es zeigt:The invention will be explained in more detail below using exemplary embodiments with reference to schematic drawings. It shows:
Fig. 1 ein Funktionsschema einer Zahnbürste mit zwei Griffteilen,1 is a functional diagram of a toothbrush with two handle parts,
Fig. 2 eine Zahnbürste, bei der die Griffteile durch Pendelstege mit¬ einander verbunden sind,2 shows a toothbrush in which the handle parts are connected to one another by pendulum webs,
Fig. 3 eine Zahnbürste, bei der die Griffteile durch separat einge¬ setzte Stege verbunden sind,3 shows a toothbrush in which the handle parts are connected by webs which are inserted separately,
Fig. 4 eine Zahnbürste, bei der die Griffteile durch ein weiches flexibles Material verbunden sind,4 is a toothbrush in which the handle parts are connected by a soft, flexible material,
Fig. 5 eine Zahnbürste mit in einem Halter verschiebbaren Halterteilen, Fig. 6 einen Schnitt entlang Linie VII-VII in Fig. 5.5 shows a toothbrush with holder parts which can be displaced in a holder, 6 shows a section along line VII-VII in FIG. 5.
Jede Zahnbürste weist einen Bürstenkopf 1 auf, der aus einer Platte 2 besteht, in die einseitig Borstenbündel 3 eingesetzt sind. Ein ge¬ gebenenfalls verjüngtes und/oder mit einem nicht dargestellten Vor¬ sprung versehenes Ende 4 der Platte 2 ist gelenkig und zugfest mit einem Griff 5 verbunden, wobei der Griff 5 geradlinig (Fig. 5) oder gewinkelt (Fig. 1 bis 4) ausgeführt sein kann.Each toothbrush has a brush head 1, which consists of a plate 2, in which bristle bundles 3 are inserted on one side. A possibly tapered and / or provided with a projection (not shown) end 4 of the plate 2 is articulated and tensile connected to a handle 5, the handle 5 being straight (FIG. 5) or angled (FIGS. 1 to 4) can be executed.
Fig. 2 zeigt ein derartiges Ausführungsbeispiel, bei dem die Griff- teile 7 z.B. durch Anspritzen mit Pendelstegen 81 verbunden sind, wobei deren Anlenkpunkte 11 an den Griffteilen 7 und an der Platte 2 zur Erhöhung der Beweglichkeit ausgedünnt bzw. eingekerbt sind bzw. sein können. Hierdurch werden Scharniere gebildet.2 shows such an exemplary embodiment, in which the handle parts 7 are connected, for example by injection molding, to pendulum webs 8 1 , the articulation points 11 of which are thinned or notched on the handle parts 7 and on the plate 2 to increase mobility can. This creates hinges.
Bei dem in Fig. 3 dargestellten Ausführungsbeispiel sind parallel zueinander ausgerichtete separate Stege 8' ' zwischen den Griffteilen 7 befestigt.In the embodiment shown in FIG. 3, separate webs 8 ″ aligned parallel to one another are fastened between the handle parts 7.
Bei dem in Fig. 4 dargestellten Ausführungsbeispiel sind die beiden Griffteile 7 durch eine elastische, z.B. schaumartige Zwischenlage 12 miteinander verbunden, die eine relative Bewegung der beiden Griffteile 7 gegeneinander ermöglicht.In the embodiment shown in Fig. 4, the two handle parts 7 are separated by an elastic, e.g. Foam-like intermediate layer 12 connected to each other, which enables a relative movement of the two handle parts 7 against each other.
Es besteht auch die Möglichkeit, die geraden Teilstücke bei ge¬ winkelten Griffen 5 oder die ganzen Griffteile 7, wenn sie gerade sind, direkt miteinander zu kuppeln, z.B. in der Art einer Schwalbenschwanzführung. Hierbei können geeignete Maßnahmen zur Verringerung der Reibung z.B. durch Verringerung der Kontaktflächen und anderes mehr vorgesehen werden.There is also the possibility of coupling the straight sections with angled handles 5 or the entire handle parts 7 if they are straight, e.g. in the manner of a dovetail guide. Suitable measures to reduce the friction e.g. by reducing the contact areas and more.

Bei dem schematisch in Fig. 5 dargestellten Ausführungsbeispiel weist der Griff 5 einen Halter 13 auf, der an der oberen Kante 9 mit dem Ende 4 der Platte 2 des Bürstenkopfeε 1 gelenkig aber zugfest verbunden ist. Die gelenkige Verbindung kann durch MaterialVerdünnung mittels eines Zugteils oder auch eines Kugelgelenkes erfolgen. Im Halter 13 sind um jeweeils 90° versetzt drei Griffteile 14 verschiebbar angeordnet, deren zum Bürstenkopf 1 gerichtete Enden an den drei freien um jeweils 90° versetzten Kanten des Endes 4 der Platte 2 angelenkt sind. Durch diese Ausführung ist der Bürstenkopf 1 in praktisch jeder Richtung durch Bewegen einzelner oder mehrer Griffteile 14 verstellbar. In the exemplary embodiment shown schematically in FIG. 5, the handle 5 has a holder 13 which is connected at the upper edge 9 to the end 4 of the plate 2 of the brush head 1 in an articulated but tensile manner. The articulated connection can be made by thinning the material by means of a tension member or a ball joint. In the holder 13 are offset by 90 ° each three handle parts 14 slidably arranged, the ends directed towards the brush head 1 are articulated on the three free edges of the end 4 of the plate 2, each offset by 90 °. With this design, the brush head 1 can be adjusted in practically any direction by moving individual or multiple handle parts 14.
