Description

Zahnbürste für Zahnprothesen Toothbrush for dentures
Die Erfindung betrifft eine Zahnbürste für Zahnpro¬ thesen, bestehend aus einem Handgriff und einem sich anschließenden Borstenträger, der konvex gekrümmt aus¬ gebildet ist und an seiner konvexen Außenseite mit Reinigungsborsten versehen ist.The invention relates to a toothbrush for dental prostheses, consisting of a handle and an adjoining bristle holder which is convexly curved and is provided with cleaning bristles on its convex outside.
Zahnprothesenträger oder Träger von kieferorthopädi- schen Regulierungsspangen haben im allgemeinen das Problem, die Zahnprothese oder Spange zu reinigen. Schwierig ist dieses Problem vor allem für Personen in vorgerücktem Alter, Seh- und Bewegungsbehinderte. Besonders schwierig ist die Reinigung für alle Prothe¬ senträger unterwegs, z. B. im Restaurant, wo es darauf ankommt, die Reinigung schnell und unauffällig durchzu ühren.Denture wearers or wearers of orthodontic regulation braces generally have the problem of cleaning the denture or brace. This problem is particularly difficult for people of advanced age, the visually impaired and those with movement problems. Cleaning is particularly difficult for all prosthesis wearers on the go, e.g. B. in the restaurant, where it is important to carry out the cleaning quickly and unobtrusively.
Die verbreitete chemische Reinigung ist nach neuen wissenschaftlichen Erkenntnissen der Universität Er¬ langen abzulehnen, weil die Prothesen durch den An¬ griff der aggressiven Chemikalien in Mitleidenschaft gezogen werden. Der Stand der Technik (vgl. DE-OS 33 27 129, DE-OS 36 15 936) kennt darüberhinaus auf¬ wendige elektrische Reinigungseinrichtungen mit einem speziell für diesen Reinigungszweck ausgebildeten Bürstensatz. Solche Einrichtungen sind lediglich für das häusliche Badezimmer geeignet und können nicht ständig mitgeführt werden. Aus diesem Grunde sind nach dem Stande der Technik (DE-GM 87 15 690) auch pinselartige Reinigungsgeräte bekannt, die in einem schmalen Büschel angeordnete Reinigungsborsten aufwei¬ sen, die von einer aufschraubbaren Schutzkappe abge- deckt sind, so daß die gesamte Reinigungsvorrichtung etwa die Form eines Füllfederhalters hat. Die Reini¬ gung einer Zahnprothese mit einem solchen schmalen Büschel von Reinigungsborsten ist indessen sehr müh¬ sam und zeitaufwendig.The widespread chemical cleaning is new to reject scientific knowledge from the University of Er¬langen because the prostheses are affected by the attack of the aggressive chemicals. The prior art (cf. DE-OS 33 27 129, DE-OS 36 15 936) also knows complex electrical cleaning devices with a brush set specially designed for this cleaning purpose. Such facilities are only suitable for the domestic bathroom and cannot be carried around at all times. For this reason, brush-like cleaning devices are known from the prior art (DE-GM 87 15 690), which have cleaning bristles arranged in a narrow tuft, which are covered by a screw-on protective cap, so that the entire cleaning device is approximately the same Has the shape of a fountain pen. Cleaning a dental prosthesis with such a narrow tuft of cleaning bristles is, however, very laborious and time-consuming.
Zurp Stand der Technik (DE-OS 34 24 568) gehört schließlich auch ein in einem tragbaren Etui unterge¬ brachter Reinigungssatz für Zahnprothesen, der unter anderem verschiedenartig ausgebildete Bürsten umfaßt. Zu diesem Bürstensatz gehört auch die Bürste nach dem Gattungsbegriff des Schutzanspruches 1 der vorliegen¬ den Gebrauchsmusteranmeidung. Diese vorbekannte Zahn¬ bürste mit konvex gekrümmtem Borstenträger ist jedoch nicht dazu geeignet, alle Probiemzonen von Zahnprothe¬ sen oder Zahnspangen, wie zum Beispiel enge Höhlungen, Vertiefungen, Rinnen oder dergleichen zu¬ verlässig und schnell zu reinigen. Das ergibt sich allein schon daraus, daß diese vorbekannte Bürste lediglich Bestandteil eines Bürstensatzes ist, deren einzelne Bürsten jeweils bestimmten Funktionen bei der Reinigung von Prothesen angepaßt sind. Es ist Aufgabe der Erfindung, die Zahnbürste nach dem Gattungsbegriff des Schutzanspruches 1 dahingehend weiterzubilden, daß eine schnelle und zuverlässige Reinigung aller Problemzonen von Zahnprothesen oder Zahnspangen mit einer einzigen Zahnbürste möglich ist.Finally, the prior art (DE-OS 34 24 568) also includes a cleaning set for dental prostheses, which is accommodated in a portable case and which, among other things, comprises brushes of various types. This brush set also includes the brush according to the preamble of protection claim 1 of the present utility model avoidance. However, this previously known toothbrush with a convexly curved bristle carrier is not suitable for reliably and quickly cleaning all the problem areas of dental prostheses or braces, such as narrow cavities, depressions, channels or the like. This results from the fact that this previously known brush is only part of a brush set, the individual brushes of which are each adapted to certain functions when cleaning prostheses. It is an object of the invention to develop the toothbrush according to the preamble of protection claim 1 in such a way that a quick and reliable cleaning of all problem areas of dental prostheses or braces is possible with a single toothbrush.
Zur Lösung dieser Aufgabe schlägt die Erfindung aus¬ gehend von der Zahnbürste der eingangs genannten Art vor, daß der Borstenträger die Form einer Spirale mit zum äußeren Ende hin abnehmendem Krümmungsradius hat und daß die Borsten den Borstenträger quer zur Krüm¬ mungsebene der Spirale nach beiden Seiten überragen.To achieve this object, the invention proposes, starting from the toothbrush of the type mentioned at the outset, that the bristle carrier has the shape of a spiral with a radius of curvature decreasing towards the outer end and that the bristles support the bristle carrier transversely to the curvature plane of the spiral on both sides tower over.
Die besondere Gestalt des Borstenträgers und die An- Ordnung der Borsten machen es möglich, bei entspre¬ chender Stellung des Handgriffes die unterschiedlich geformten Bereiche des Bürstenkopfes für die Reini¬ gungsarbeit einzusetzen. Auf diese Weise kann man mit dieser Zahnbürste auch bequem die oben angeführten Problembereiche von Zahnprothesen reinigen. Da die Borsten den Borstenträger nicht nur nach außen, son¬ dern auch nach den Seiten hin überragen, wird der Borstenträger beim Eindringen in Öffnungen, Höhlungen oder Rinnen der Prothese von den Borsten geführt und im Abstand zu den Oberflächen der Prothese gehalten. Das hat den besonderen Vorteil, daß bei der Reini¬ gungsarbeit im Bereich von Rinnen, Höhlungen oder Öffnungen im wesentlichen nur die Reinigungsborsten, nicht aber der Borstenträger mit der Prothese in Berührung kommen. Diese Führung des Bürstenkopfes durch die Borsten selbst ist insbesondere für Sehbe¬ hinderte und bewegungseingeschränkte Personen wich¬ tig, die normalerweise bei der Reinigung der Prothese große Schwierigkeiten haben, den Bürstenkopf richtig zu führen. Dadurch, daß die Prothese nur mit den Reinigungsborsten, nicht aber mit dem Borstenträger in Berührung kommt, werden auch unbeabsichtigte Be¬ schädigungen der Prothese durch den starren Borsten- träger vermieden.The special shape of the bristle holder and the arrangement of the bristles make it possible to use the differently shaped areas of the brush head for the cleaning work, with the handle being in an appropriate position. In this way you can also use this toothbrush to comfortably clean the problem areas of dental prostheses listed above. Since the bristles project beyond the bristle carrier not only to the outside but also to the sides, the bristle carrier is guided by the bristles when penetrating into openings, cavities or grooves in the prosthesis and held at a distance from the surfaces of the prosthesis. This has the particular advantage that during cleaning work in the area of channels, hollows or openings, essentially only the cleaning bristles but not the bristle carrier come into contact with the prosthesis. This guiding of the brush head through the bristles themselves is particularly important for visually impaired and movement-restricted persons who normally have great difficulty in properly guiding the brush head when cleaning the prosthesis. Because the prosthesis only with the cleaning bristles, but not with the bristle holder comes into contact, unintentional damage to the prosthesis by the rigid bristle carrier is also avoided.
Eine zweckmäßige Weiterbildung der Erfindung sieht vor, daß der Querschnitt des Borstenträgers an der mit Borsten besetzten Seite etwa halbkreisförmig abge¬ rundet ist und daß die Borstenenden in jeder Quer¬ schnittsebene des Borstenträgers auf einem Kreis- oder Ellipsenbogen liegen. Hierdurch ergibt sich eine weitgehend gleichmäßige Reinigungswirkung bei allen denkbaren Stellungen des Handgriffes.An expedient development of the invention provides that the cross-section of the bristle carrier is rounded off approximately semicircularly on the side covered with bristles and that the bristle ends lie on a circular or elliptical arc in each cross-sectional plane of the bristle carrier. This results in a largely uniform cleaning effect in all conceivable positions of the handle.
Zweckmäßig ist weiterhin vorgesehen, daß die Länge der quer zur Krümmungsebene der Spirale verlaufenden Borsten zum äußeren Ende des Borstenträgers hin über dessen Länge allmählich kleiner wird. Hierdurch ist es noch besser möglich, mit dem äußeren Ende des Bürstenkopfes in schmale Hohlräume der Prothese oder der Spange einzudringen.It is furthermore expediently provided that the length of the bristles running transversely to the plane of curvature of the spiral towards the outer end of the bristle carrier gradually decreases over its length. This makes it even better possible to penetrate the narrow end of the prosthesis or brace with the outer end of the brush head.
Schließlich ist vorgesehen, daß der Polpunkt der Spi¬ rale in der Höhe der Längsachse des Handgriffes liegt. Auf diese Weise wird erreicht, daß die gewölb- ten Bereiche der Spirale den Handgriff der Zahnbürste in der' Krümmungsebene der Spirale nach beiden Seiten hin überragen. Dabei ist der sich an den Handgriff anschließende, erste Abschnitt des Bürstenkopfes nur schwach gekrümmt und mehr für die Reinigung der großen Flächen und flachen Wölbungen der Prothese ge¬ eignet. Der nach der anderen Seite vorstehende, stär¬ ker gekrümmte Teil des 3ürstenkopfes ist demgegenüber mehr für die oben diskutierten Problembereiche derFinally, it is provided that the pole point of the spiral lies at the height of the longitudinal axis of the handle. In this way it is achieved that the curved areas of the spiral project beyond the handle of the toothbrush on both sides in the plane of curvature of the spiral. The first section of the brush head adjoining the handle is only slightly curved and is more suitable for cleaning the large surfaces and flat arches of the prosthesis. The protruding part of the brush head protruding to the other side, on the other hand, is more for the problem areas discussed above
Prothese geeignet. Durch Verdrehen der Zahnbürste um 180° um die Längsachse des Handgriffes kann man den einen oder den anderen Bereich des Bürstenkopfes zum Einsatz bringen.Suitable for prosthesis. By turning the toothbrush by 180 ° around the longitudinal axis of the handle, one or the other area of the brush head can be used Bring effort.
Um einen ästhetisch ansprechenden und gegen Biegebean¬ spruchungen unempfindlichen Übergang zwischen dem im wesentlichen geradlinig verlaufenden Handgriff und dem spiralig verlaufenden Bürstenkopf zu erhalten, ist weiterhin vorgesehen, daß der Borstenträger im Übergangsbereich zum Handgriff entgegengesetzt zur Krümmung der Spirale gekrümmt ist. Dabei nimmt die Länge der Borsten im Ubergangsbereich zum Handgriff hin allmählich ab. Hierdurch wird ein optisch an¬ sprechender Übergang zwischen dem Handgriff und den langen Borsten des Bürstenkopfes geschaffen.In order to obtain an aesthetically pleasing transition that is insensitive to bending stresses, between the essentially straight handle and the spiral brush head, it is further provided that the bristle carrier in the transition area to the handle is curved opposite to the curvature of the spiral. The length of the bristles in the transition area towards the handle gradually decreases. This creates an optically appealing transition between the handle and the long bristles of the brush head.
Um die Zahnbürste in beiden Drehstellungen sicher halten und führen zu können, ist der Handgriff an seinem dem Borstenträger zugewandten Ende mit zwei gegenüberliegenden Griffmulden versehen, deren Ober¬ flächen senkrecht zur Krümmungsebene der Spirale ver- laufen.In order to be able to hold and guide the toothbrush securely in both rotational positions, the handle on its end facing the bristle holder is provided with two opposing recessed grips, the surfaces of which run perpendicular to the plane of curvature of the spiral.
Ein Ausführungsbeispiel der Erfindung wird im folgen¬ den anhand der Zeichnung näher erläutert. Es zeigen:An embodiment of the invention is explained in more detail below with reference to the drawing. Show it:
Fig. 1 Eine Zahnbürste gemäß der Erfin- düng in Seitenansicht;1 shows a toothbrush according to the invention in a side view;
Fig. 2 die Zahnbürste gemäß Fig. 1 in Draufsicht;FIG. 2 shows the toothbrush according to FIG. 1 in a top view;
Fig. 3 einen Schnitt entlang der Linie III-III in Fig. 1.3 shows a section along the line III-III in FIG. 1.
In der Zeichnung ist der Handgriff der Zahnbürste mit dem Bezugszeichen 1 bezeichnet. Der Handgriff 1 weist zwei einander gegenüberliegende Griffmulden 2 und ei- nen verjüngten Endbereich 3 auf. Am vorderen Ende geht der Handgriff 1 in einen Borstenträger 4 über, der einen etwa halbkreisförmigen Querschnitt hat und in Seitenansicht (Fig. 1) etwa die Form einer Spirale mit sich über die Länge verkleinerndem Krümmungsra¬ dius hat. Der Polpunkt dieser Spirale liegt etwa in der Verlängerung der Längsachse des Handgriffes 1, derart, daß der schwächer gekrümmte Bereich der Spirale in Fig. 1 oberhalb der Längsachse des Hand- griffes 1 und der stärker gekrümmte Bereich der Spirale unterhalb dieser Längsachse liegen. Zwischen der Spirale und dem Handgriff 1 "befindet sich ein Übergangsbereich 4a des Borstenkopfes 4, der entgegen¬ gesetzt zur Krümmung der Spirale gekrümmt ist.In the drawing, the handle of the toothbrush is designated by the reference number 1. The handle 1 has two opposing recessed grips 2 and a NEN tapered end portion 3. At the front end, the handle 1 merges into a bristle carrier 4, which has an approximately semicircular cross section and, in a side view (FIG. 1), has approximately the shape of a spiral with a radius of curvature that decreases over the length. The pole point of this spiral lies approximately in the extension of the longitudinal axis of the handle 1, such that the weakly curved area of the spiral in FIG. 1 lies above the longitudinal axis of the handle 1 and the more curved area of the spiral lies below this longitudinal axis. Between the spiral and the handle 1 " there is a transition region 4a of the bristle head 4, which is curved in the opposite direction to the curvature of the spiral.
Die konvex gekrümmte Außenseite des Borstenträgers 4 ist mit Borsten 5 besetzt. Diese Borsten 5 verlaufen etwa senkrecht zur Oberfläche des Borstenträgers 4 und überragen den Borstenträger 4 quer zur Krümmungs- ebene der Spirale nach beiden Seiten hin. Die Enden der Borsten 5 liegen in Bezug auf jeden Querschnitt des Borstenträgers 4 etwa auf einem Kreisbogen oder Ellipsenbogen (vgl. Fig. 3 ). Die Länge der seitlich vorstehenden Borsten 5 wird zum Ende des Borstenträ- gers 4 hin allmählich kleiner, so daß man mit dem Ende des Bürstenkopfes 4, 5 besser in enge Höhlungen oder Rinnen der Prothese eindringen kann. Im Über¬ gangsbereich 4a nimmt die Länge der Borsten 5 zum Handgriff 1 hin allmählich ab, so daß sich optisch ein fließender Übergang zwischen dem Handgriff 1 und dem Bürstenkopf 4, 5 ergibt. The convexly curved outside of the bristle carrier 4 is covered with bristles 5. These bristles 5 run approximately perpendicular to the surface of the bristle carrier 4 and project beyond the bristle carrier 4 transversely to the plane of curvature of the spiral on both sides. The ends of the bristles 5 lie in relation to each cross section of the bristle carrier 4 approximately on an arc of a circle or an ellipse (cf. FIG. 3). The length of the laterally projecting bristles 5 gradually becomes smaller towards the end of the bristle carrier 4, so that the end of the brush head 4, 5 can better penetrate narrow cavities or grooves in the prosthesis. In the transition area 4a, the length of the bristles 5 gradually decreases toward the handle 1, so that there is a visually smooth transition between the handle 1 and the brush head 4, 5.
