Description

Bürste brush
Die Erfindung betrifft eine Bürste, insbesondere eine Zahnbürste, mit einem in Verlängerung eines Griffs ange¬ ordneten, mit Borsten versehenen Bürstenkopf.The invention relates to a brush, in particular a toothbrush, with a brush head arranged in the extension of a handle and provided with bristles.
Bei den gebräuchlichen Bürsten dieser Art ist der Bür- stenkopf starr ausgebildet. Der Bürstenkopf kann dabei zwar konkav oder konvex gewölbt sein. Es ist jedoch nicht möglich, die vorhandene Form zu ändern. Die Folge davon ist, daß immer nur ein zur vorliegenden Bürstenform pas¬ sender Gebissteil zufriedenstellend gereinigt werden kann.In the case of the usual brushes of this type, the brush head is rigid. The brush head can be concave or convex. However, it is not possible to change the existing form. The consequence of this is that only one part of the denture that matches the shape of the brush can be satisfactorily cleaned.
Es ist auch schon vorgeschlagen worden, einen flexiblen Bürstenkopf vorzusehen und diesen auf einem S-förmig ge¬ bogenen Griff verschiebbar aufzunehmen. Hierbei ist zwar eine Änderung der Bürstenwölbung möglich, indem der Bür¬ stenkopf von einem Ende des S-förmig gebogenen Griffs zum anderen Ende verschoben wird. Die dabei erzielbare Wöl¬ bung des Bürstenkopfes ist jedoch durch die Konfiguration des S-förmig gebogenen Griffs fest vorgegeben. Eine von der Krümmung des Griffs abweichende Wölbung des Bürsten¬ kopfes ist dagegen nicht möglich. Auch hierbei besteht daher die Gefahr, daß einzelne Stellen des Gebisses nicht zufriedenstellend gereinigt werden können. Außerdem macht der genannte Vorschlag einen vergleichsweise komplizier¬ ten Bürstenaufbau erforderlich und führt zu einer schwie¬ rigen Handhabung. Der genannte Vorschlag erweist sich da¬ her auch als nicht bedienungsfreundlich genug.It has also been proposed to provide a flexible brush head and to slidably receive it on an S-shaped handle. This is true a change in the brush curvature is possible by moving the brush head from one end of the S-shaped handle to the other end. However, the curvature of the brush head that can be achieved is fixed by the configuration of the S-shaped handle. On the other hand, a curvature of the brush head that deviates from the curvature of the handle is not possible. Here, too, there is therefore the risk that individual parts of the bit cannot be cleaned satisfactorily. In addition, the proposal mentioned requires a comparatively complicated brush structure and leads to difficult handling. The proposal mentioned therefore also proves to be not user-friendly enough.
Hiervon ausgehend ist es daher die Aufgabe der vorliegen¬ den Erfindung, eine Bürste eingangs erwähnter Art zu schaffen, die trotz Beibehaltung des bewährten Aufbaus mit fest an den Griff angesetzem Bürstenkopf einen in seiner Wölbung individuell verstellbaren Bürstenkopf auf¬ weist.Proceeding from this, it is therefore the object of the present invention to create a brush of the type mentioned at the outset which, despite maintaining the proven design with a brush head firmly attached to the handle, has a brush head which can be individually adjusted in its curvature.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Bürstenkopf zumindest in einer Ebene flexibel ausge¬ bildet ist und daß am griffsfernen Ende des Bürstenkopfes ein Zug- und Schubelement angreift, das andererseits an einem auf dem Griff verstellbar aufgenommenen, arretier¬ baren Betätigungsorgan befestigt ist.This object is achieved according to the invention in that the brush head is flexible at least in one plane and that a pulling and pushing element acts on the end of the brush head remote from the handle, which is attached on the other hand to an actuating member which is adjustably received on the handle.
Diese Maßnahmen ermöglichen in vorteilhafter Weise eine exakte Anpassung der Bürstenwölbung an die Verhältnisse des Einzelfalls und ermöglichen daher in jedem Fall die Erzielung eines optimalen Reinigungseffekts. Dennoch ist es möglich, den bewährten Bürstenaufbau mit fest an den Griff angesetztem Bürstenkopf beizubehalten, was nicht nur eine einfache Handhabung, sondern auch einen einfa¬ chen und robusten Aufbau gewährleistet.These measures advantageously allow an exact adaptation of the brush curvature to the circumstances of the individual case and therefore enable the in any case Achieving an optimal cleaning effect. Nevertheless, it is possible to maintain the proven brush structure with the brush head firmly attached to the handle, which not only ensures simple handling, but also a simple and robust structure.
Vorteilhafte Weiterbildungen und zweckmäßige Ausgestal¬ tungen der übergeordneten Maßnahmen sind in den Unteran- sprüchen angegeben. So kann das Zug- und Schubelement zweckmäßig als bandförmige Blattfeder ausgebildet sein. Ein derartiges Element kann sich in vorteilhafter Weise unter Beibehaltung der Zug- bzw. Schubwirkung leicht je¬ der Wölbung anpassen und ergibt zudem eine elastische Rückstellkraft.Advantageous further developments and expedient configurations of the superordinate measures are specified in the subclaims. The pulling and pushing element can expediently be designed as a band-shaped leaf spring. Such an element can advantageously adapt easily to each curvature while maintaining the pulling or pushing effect and also results in an elastic restoring force.
Eine weitere vorteilhafte Maßnahme kann darin bestehen, daß der Bürstenkopf eine die Borsten aufnehmende, flexi¬ ble Leiste aufweist, die mit in Längsrichtung mit Abstand hintereinander angeordneten, portalförmigen Jochen ver¬ sehen ist. Die mit Abstand hintereinander angeordneten Joche ergeben ein Tunnel für eine geschützte Anordnung des Zug- und Schubelements und ermöglichen gleichzeitig die erforderliche Beweglichkeit des Bürstenkopfes.A further advantageous measure can consist in the brush head having a flexible strip which receives the bristles and which is provided with portal-shaped yokes arranged one behind the other in the longitudinal direction. The yokes, which are arranged one behind the other at a distance, create a tunnel for a protected arrangement of the pulling and pushing elements and at the same time allow the required mobility of the brush head.
Weitere vorteilhafte Ausgestaltungen und zweckmäßige Fortbildung der übergeordneten Maßnahmen ergeben sich aus den restlichen Unteransprüchen in Verbindung mit der nachstehenden Beispielsbeschreibung.Further advantageous refinements and appropriate further training of the superordinate measures result from the remaining subclaims in connection with the example description below.
Nachstehend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher erläutert. Hierbei zeigen: Figur 1 eine Seitenansicht einer erfindungsgemäßenAn exemplary embodiment of the invention is explained in more detail below with reference to the drawing.

Die der Zeichnung zugrundeliegende Zahnbürste besteht, wie beispielsweise die Figur 1 erkennen läßt, aus einem stielformigen Griff 10, der einen in seiner Verlängerung angeordneten Bürstenkopf 11 trägt. Dieser ist mit reihen- förmig angeordneten Borstenbüscheln 12 versehen. Der Bür¬ stenkopf 11 ist in zur Mittellängsebene der Bürste paral¬ leler Richtung flexibel verformbar, d. h. bezüglich einer zur Mittellängsebene quer verlaufenden Achse wölbbar. Der Bürstenkopf 11 kann dabei von der der Figur 1 zugrunde¬ liegenden, borstenseitigen Konvexwölbung über die der Fi¬ gur 2 zugrundeliegende Streckstellung in die der Figur 3 zugrundeliegende konkav gewölbte Stellung gebracht werden. Alternativ oder zusätzlich zur Flexibilität parallel zur Mittellängsebene wäre auch eine Flexibilität quer hierzu denkbar. Der Bürstenkopf 11 besteht, wie am besten aus Figur 5 er¬ kennbar ist, aus einer flexiblen, an den Griff angeform¬ ten Basisleiste 11a, in die die Borstenbüschel 12 einge¬ setzt sind, und die auf der von den Borstenbüscheln .12 abgewandten Seite von mit Abstand hintereinander angeord¬ neten, portalförmigen Jochelementen 11b übergriffen wird. Diese begrenzen dementsprechend einen den Bürstenkopf 11 durchsetzenden Tunnel 18. Die Unterseite der Basisleiste 11a schließt bündig an die Unterseite des benachbarten Griffs 10 an. Die Oberseite der Jochelemente 11b geht bündig in die Oberseite des benachbarten Griffs 10 über. Zwischen den einander benachbarten Jochelementen 11b sind Lücken 13 vorgesehen. Diese ermöglichen trotz einer ver¬ gleichsweise großen Gesamtdicke des Bürstenkopfes 11 eine ungehinderte Flexiblität parallel zur Mittellängsebene. Die die Borstenbüschel 12 aufnehmende Basisleiste 11a fungiert praktisch als Federleiste, die nach einer Aus¬ lenkung automatisch in die der Figur 2 zugrundeliegende Streckstellung zurück kehrt.The toothbrush on which the drawing is based, as shown for example in FIG. 1, consists of a handle-shaped handle 10 which carries a brush head 11 arranged in its extension. This is provided with bristle tufts 12 arranged in a row. The brush head 11 can be flexibly deformed in the direction parallel to the central longitudinal plane of the brush, ie it can be arched with respect to an axis running transversely to the central longitudinal plane. The brush head 11 can be brought from the bristle-side convex curvature on which FIG. 1 is based, via the stretching position on which FIG. 2 is based, to the concavely arched position on which FIG. 3 is based. As an alternative or in addition to the flexibility parallel to the central longitudinal plane, flexibility across this would also be conceivable. The brush head 11 consists, as can best be seen from FIG. 5, of a flexible base strip 11a molded onto the handle, into which the bristle tufts 12 are inserted, and on the side facing away from the bristle tufts .12 is overlapped by portal-shaped yoke elements 11b arranged one behind the other at a distance. These accordingly limit a tunnel 18 passing through the brush head 11. The underside of the base strip 11a is flush with the underside of the adjacent handle 10. The top of the yoke elements 11b merges flush with the top of the adjacent handle 10. Gaps 13 are provided between the adjacent yoke elements 11b. Despite a comparatively large overall thickness of the brush head 11, these enable unhindered flexibility parallel to the central longitudinal plane. The base strip 11a receiving the bristle tufts 12 practically functions as a spring strip which, after a deflection, automatically returns to the extended position on which FIG. 2 is based.
Am griffernen Ende der Basisleiste 11b greift ein durch den Tunnel 18 hindurchgeführtes Zug- und Schubelement 14 an, das andererseits an einem Betätigungsorgan 16 in Form einer verschiebbar auf dem Griff 10 aufgenommenen, arre¬ tierbaren Schiebenocke befestigt ist. Das Schub- und Zug¬ element 14 ist als bandförmige Blattfeder ausgebildet, deren Enden mit der Basisleiste lla bzw. dem Betätigungs¬ organ 16 verstiftet sein können, wie bei 15 angedeutet ist. Die das Schub- und Zugelement 14 bildende Blattfeder wird durch Verschieben des Betätigungsorgans 16" zum Bür- stenkopf hin gestaucht und durch Verschieben des Betäti¬ gungsorgans 16 vom Bürstenkopf 11 weg gespannt. Da das Zug- und Schubelement 14 die Basisleiste 11a übergreift, wird diese, wie die Figur 1 zeigt, im Falle einer Anspan¬ nung des Zug- und Schubelements 14 nach unten, d.h. bor¬ stenseitig konvex gewölbt. Im Falle einer Stauchung des Zug- und Schubelements 14 wird die Basisleiste 11a, wie die Figur 3 zeigt, nach oben, d.h. borstenseitig konkav durchgewölbt. Um dies zu erleichtern, kann der den Tunnel 18 durchgreifende Abschnitt der das Zug- und Schubelement 14 bildenden Blattfeder durch Formgebung bzw. Vorspannung so ausgebildet sein, daß im Falle einer Stauchung eine nach oben gerichtete Wölbung erfogt.At the gripping end of the base bar 11b, a pulling and pushing element 14 engages through the tunnel 18, which on the other hand is fastened to an actuating member 16 in the form of a lockable sliding cam which is slidably received on the handle 10. The push and pull element 14 is designed as a band-shaped leaf spring, the ends of which can be pinned to the base strip 11a or the actuating member 16, as indicated at 15. The leaf spring forming the push and pull element 14 is moved to the office by moving the actuating member 16 " . sten head compressed and tensioned by moving the actuator 16 away from the brush head 11. Since the pulling and pushing element 14 engages over the base strip 11a, this is, as shown in FIG. 1, in the event of tensioning of the pulling and pushing element 14 downward, ie convexly curved on the bristle side. In the event of compression of the pulling and pushing element 14, the base strip 11a, as shown in FIG. 3, is arched upwards, ie concavely on the bristle side. In order to facilitate this, the section of the leaf spring forming the pulling and pushing element 14 penetrating through the tunnel 18 can be designed by shaping or pretensioning such that an upward curvature occurs in the event of a compression.
Die das Betätigungsorgan 16 bildende Schiebenocke kann, wie am besten aus Figur 4 erkennbar ist, mit einem in eine Nut 19 des Griffs 10 eingreifenden Zapfen 17 verse¬ hen sein. An diesem ist im dargestellten Beispiel das Zug- und Schubelement 14 befestigt. Die Nut 19 besitzt mehrere, hier durch bohrungsför ige Querschnittserweite¬ rungen gebildete Rastkerben 20, in welche der Zapfen 17 beim Verschieben des Betätigungsorgans 16 einrastbar ist. Der Querschnitt des als Rastkopf fungierenden Zapfens 17 entspricht dementsprechend in etwa dem Querschnitt der als Rastkerben 20 fungierenden Querschnittserweiterungen der Nut 19. Die Rastkerben 20 sind jeweils unterschiedli¬ chen Wölbungen des Bürstenkopfes 11 zugeordnet. Im dar¬ gestellten Beispiel sind lediglich drei Rastkerben 20 an¬ gedeutet, wobei die mittlere Rastkerbe der der Figur 2 zugrundeliegenden Streckstellung und die beiden äußeren Rastkerben den den Figuren 1 und 3 zugrundeliegenden Wöl- bunden zugeordnet sein sollen. Sofern neben den darge¬ stellten Extremstellungen weitere Zwischenstellungen ein¬ stellbar sein sollen, sind einfach weitere Rastkerben vorzusehen.The sliding cam forming the actuating member 16 can, as can best be seen from FIG. 4, be provided with a pin 17 engaging in a groove 19 of the handle 10. The pulling and pushing element 14 is fastened to this in the example shown. The groove 19 has a plurality of notches 20, which are formed here by bore-shaped cross-sectional expansions, into which the pin 17 can be latched when the actuating member 16 is moved. The cross section of the pin 17 acting as a locking head corresponds approximately to the cross section of the cross-sectional expansions of the groove 19 functioning as locking notches 20. The locking notches 20 are each assigned different curvatures of the brush head 11. In the example shown, only three notches 20 are indicated, the middle notch of the stretching position on which FIG. 2 is based and the two outer notches of the bulges on which FIGS. 1 and 3 are based. should be assigned to bundles. If further intermediate positions are to be adjustable in addition to the extreme positions shown, further locking notches are simply to be provided.
Die Nut 19 kann auf dem Griff 10 so positioniert sein, daß sie direkt an den Tunnel 18 des Bürstenkopfes 11 an¬ schließt. Im dargestellten Beispiel ist die Nut 19 vom Bürstenkopf 11 beabstandet. Dementsprechend ist der Griff 10 mit einem einerseits in den Tunnel 18 und andererseits in die Nut 19 einmündenden, durch eine Längsausnehmung gebildeten Führungskanal 21 versehen, durch den die das Zug- und Schubelement 14 bildende Blattfeder durchsteck¬ bar ist. Der Führungskanal 21 ergibt eine exakte Gerad¬ führung des durchgesteckten Zug- und Schubelements 14, so daß dieses griffseitig nicht ausweichen kann. Im Gegen¬ satz dazu ist, wie am besten aus Figur 5 ersichtlich ist, der lichte Querschnitt des Tunnels 18 gegenüber dem Quer¬ schnitt des Zug- und Schubelements 14 vergrößert.The groove 19 can be positioned on the handle 10 so that it connects directly to the tunnel 18 of the brush head 11. In the example shown, the groove 19 is spaced from the brush head 11. Accordingly, the handle 10 is provided with a guide channel 21, which opens on the one hand into the tunnel 18 and on the other hand into the groove 19 and is formed by a longitudinal recess, through which the leaf spring forming the pulling and pushing element 14 can be pushed. The guide channel 21 results in exact straight guidance of the push-pull and push-in element 14, so that it cannot deflect on the handle side. In contrast to this, as can best be seen from FIG. 5, the clear cross section of the tunnel 18 is enlarged compared to the cross section of the pulling and pushing element 14.
Der vorstehenden Beispielsbeschreibung liegt zwar eine von Hand bewegbare Zahnbürste zugrunde. Selbstverständ¬ lich wäre es aber auch denkbar, die erfindungsgemäßen Maßnahmen im Rahmen einer motorisch bewegbaren Bürste, beispielsweise einer elektrisch oder durch Wasserkraft bewegbaren Bürste, zur Anwendung zu bringen. The example description above is based on a toothbrush that can be moved by hand. Of course, it would also be conceivable to apply the measures according to the invention in the context of a brush that can be moved by motor, for example a brush that can be moved electrically or by hydropower.
