Abstract

Die Erfindung bezieht sich auf eine Art Zahnhygienebürsten, die mit zwei borstentragenden Köpfen den kompletten Dentalraum mit Zahnfleisch und Zähnen pflegt und behandelt.The invention relates to a type of dental hygiene brush, the complete dental room with two bristle-bearing heads cares and treats with gums and teeth.

Das Problem die Borsten, die mit den Borstenenden, mit einem Putzspalt dazwischen, die sich spiegelbildlich gegenüberstehen, wird mit einer neuen technischen Möglichkeit durch ein Andoggen der borstentragenden Köpfe gelöst. Maschinelle und Handmontage mit drei Teilen, die spiegelbildlich zueinander passen, oder ein rechtes und linkes Teil erforderlich machen. Ein Anschlag im federnden Bereich des Kopfes verhindert ein Zusammenfallen der Borsten ineinander. Ein Basisteil im Spritz- oder Gießverfahren hergestellt, ermöglicht eine automatische Komplettmontage.

Figure 00000001
The problem of the bristles with the bristle ends, with a cleaning gap between them, which are opposite each other in a mirror image, is solved with a new technical possibility by andogging the bristle-bearing heads. Mechanical and manual assembly with three parts that mirror each other, or require a right and left part. A stop in the resilient area of the head prevents the bristles from collapsing into one another. A base part manufactured by injection or casting enables automatic complete assembly.
