Abstract

The toothbrush has a plate (1) supporting rows of bristles (3) and comprising a magnet at its each end, where the plate is of curved shape. The bristles are implanted perpendicular to the plate, where certain rows of bristles are longer than the other rows. The short rows of bristles rub the surfaces of teeth while the longer rows of bristles penetrate into interdental spaces.

Description

De nombreuses brosses à dents présentent une surface plane de l'ensembleMany toothbrushes have a flat surface of the whole

des poils constituant la brosse à dents. Celles-ci présentent l'inconvénient majeur constitué par cette surface, qui, prenant appui sur la surface extérieure des dents, ne permet pas aux poils de brosse qui se trouvent donc vis-à-vis des interstices dentaires  bristles constituting the toothbrush. These have the major disadvantage constituted by this surface, which, resting on the outer surface of the teeth, does not allow the bristles which are therefore vis-à-vis the dental interstices

de pénétrer correctement dans ces intervalles qu'il y a pourtant lieu de nettoyer efficacement. (Les poils en regard sont trop courts à ce moment là).  to penetrate properly in these intervals that it is nevertheless necessary to clean effectively. (The hairs are too short at this time).

Si l'on observe la brosse proposée (figure 1), la plaque (1) servant de support aux poils de brosse est perpendiculaire à la ligne d'axe (a figure 1) du manche (2) ; Le plan de friction constitué par l'ensemble des poils et du support ne présente plus une surface plane mais au contraire incurvée (1) ; le milieu de la courbe décrite se trouve perpendiculaire à l'axe du manche, les extrémités de l'arc de cercle situées à gauche et à droite du manche étant elles dans une projection avancée par rapport au manche.  If we observe the brush proposed (Figure 1), the plate (1) for supporting the bristles is perpendicular to the axis line (a Figure 1) of the handle (2); The friction plane formed by the set of bristles and the support no longer has a flat but curved surface (1); the middle of the curve described is perpendicular to the axis of the handle, the ends of the arc to the left and right of the handle being they in an advanced projection relative to the handle.

Nous obtenons ainsi une surface sensiblement parallèle à celle que représente la forme des mâchoires humaines, et, notamment sur le devant de la bouche; ainsi d'une part elle facilitera son introduction dans la bouche au fur et à mesure du déplacement de la dite brosse, et d'autre part, elle se rapprochera de la forme anatomique des mâchoires humaines.  We thus obtain a surface substantially parallel to that which represents the shape of the human jaws, and especially on the front of the mouth; thus on the one hand it will facilitate its introduction into the mouth as the displacement of the said brush, and secondly, it will approach the anatomical shape of the human jaws.

Les poils de la brosse ne sont plus d'aspect rectiligne (figure 2) ; leur implantation ou leur mise à longueur suivant la technique de fabrication donne un aspect en arc de cercle.  The bristles of the brush are no longer rectilinear (Figure 2); their implantation or their length according to the manufacturing technique gives an appearance in an arc.

La réalisation convexe de l'implantation des poils (figure 3) constituant la brosse dans le cas proposé fait qu'au contraire, et, surtout en raison du mode de brossage conseillé, c'est-à-dire: vertical (de haut en bas de la dent) et non plus horizontal comme c'est le cas pour la majorité des brosses actuelles. Les poils les plus longs qui passeront entre les dents, auront alors tout le loisir de pénétrer dans les interstices interdentaires, ceci renforcera donc l'efficacité du brossage.  The convex realization of the implantation of the bristles (FIG. 3) constituting the brush in the proposed case makes it, on the contrary, and, above all, because of the recommended brushing mode, that is to say: vertical (from top to bottom). bottom of the tooth) and no longer horizontal as is the case for most current brushes. The longer hairs that pass between the teeth, will then have the opportunity to enter the interdental interstices, this will enhance the effectiveness of brushing.

On peut tout aussi bien envisager que si nous continuons à observer (figure 3) la brosse de profil, ou par le dessus, certaines rangées de poils perpendiculaires à la plaque de la brosse (1) sont plus longues que d'autres. Le fait de faire glisser la brosse non seulement en vertical au moment du brossage, mais simultanément en latéral pour le déplacement de la brosse, nous aurons alors les rangées les plus longues qui pourront pénétrer efficacement dans les interstices inter-dentaires pendant que les rangées les plus courtes seront-elles occupées à brosser les surfaces dentaires qui leur seront présentées à ce moment là.  We can also consider that if we continue to observe (Figure 3) the profile brush, or from above, some rows of bristles perpendicular to the brush plate (1) are longer than others. Sliding the brush not only vertically at the time of brushing, but simultaneously at the side for brush movement, we will have the longest rows that can effectively penetrate the interstitial gaps while the rows Shorter will they be busy brushing the dental surfaces that will be presented to them at that time.

Ceci représente un avantage non négligeable par rapport aux brosses dites "conventionnelles" et contribuera à la lutte contre la plaque dentaire: Les rangées de poils sont donc perpendiculaires à la plaque (1) de l'élément brossant, de plus, les longues rangées de poils sont différentes de façon à ce que certaines rangées plus longues pénétreront dans les espaces inter-dentaires pendant que dans le même temps certaines rangées plus courtes frotteront les surfaces des dents qui leur seront présentées.  This represents a significant advantage over so-called "conventional" brushes and will contribute to the fight against dental plaque: The rows of bristles are therefore perpendicular to the plate (1) of the brushing element, moreover, the long rows of The bristles are different so that some longer rows will penetrate the interdental spaces while at the same time some shorter rows will rub the surfaces of the teeth that will be presented to them.

Pour renforcer son efficacité et afin de mieux lutter contre les maladies bactériennes buccales, chaque extrémité du corps de la brosse comporte un aimant (4) propre à limiter la formation de la plaque dentaire, donc, à améliorer encore l'hygiène bucco-dentaire.  To enhance its effectiveness and to better fight against oral bacterial diseases, each end of the body of the brush has a magnet (4) to limit the formation of dental plaque, so to further improve oral hygiene.
