Abstract

The invention relates to a toothbrush comprising bristles disposed in such a way as to create a guide space (E) which, during brushing, ensures that the bristles are kept in close contact with the anatomy of the teeth. Guide bristles delimit the guide space and are disposed in a V-shape with a truncated point so that they are ideally positioned in the dental plaque retention areas. The guide bristles are vertical or angular and are at least 3mm taller than the bristles disposed inside the guide space (E). In the case of brushes with bristles that are disposed outside the guide space (E), the height of said bristles can be smaller than or equal to that of the guide bristles so as to reinforce the action of the guide bristles .

Description

La présente invention concerne une brosse à dents destinée à atteindre plus facilement les zones de plaque lors d'un mouvement de translation sur les arcades dentaires en étant guidé par l'implantation spécifique des soies. The present invention relates to a toothbrush intended to more easily reach the plate areas during a translational movement on the dental arches being guided by the specific implantation of the bristles.

Cette brosse est constituée d'un manche (II) et d'une partie active (I) FIG 1, FIG 2 et FIG 3. This brush consists of a handle (II) and an active part (I) FIG 1, FIG 2 and FIG 3.

La partie active (I) est constituée d'une surface (A) partie supérieure arrondie ou triangulaire à pointe arrondie et de longueur (d) de 4 à 7 mm, et d'une surface (B) partie inférieure rectangulaire (FIG 2), ovoïde (FIG 3) ou triangulaire (FIG 1) dont la pointe est arrondie et est dirigée vers le manche (II) et de longueur (c) de 15 et 25 mm. The active part (I) consists of a surface (A) rounded or triangular upper part with rounded tip and length (d) of 4 to 7 mm, and a surface (B) rectangular lower part (FIG 2) , ovoid (FIG 3) or triangular (FIG 1) whose tip is rounded and is directed towards the handle (II) and length (c) of 15 and 25 mm.

Les touffes situées sur la partie supérieure (A), sont verticales ou angulées et d'une hauteur comprise entre 7 et 9mm. The tufts on the upper part (A), are vertical or angled and a height between 7 and 9mm.

Les touffes situées sur la partie inférieure (B) sont positionnées de façon à constituer un espace dit espace guide déterminé par une hauteur et un lieu d'implantation spécifique. The tufts located on the lower part (B) are positioned so as to constitute a space called guide space determined by a specific height and location.

Des touffes dites touffes guides sont disposées sur la partie inférieure (B) en forme de V, dont la pointe est tronquée et dirigée vers le manche, dont l'angle ss du V est inférieur à 150 eut délimitant un espace dit espace guide (E). Des touffes plus hautes dites touffes guides sont disposées latéralement sur de cette partie inférieure (B). Tufts said tufts guides are arranged on the bottom portion (B) V-shaped, the tip is truncated and directed towards the handle, whose angle ss V is less than 150 having delimiting a space called guide space (E ). Higher tufts called guide tufts are arranged laterally on this lower part (B).

Ces touffes guides sont d'une longueur de 8 à 12 mm et sont disposées symétriquement par rapport à un axe médian longitudinal médian (oc). La distance (a) séparant les extrémités de deux touffes guides symétriques par rapport à

l'axe longitudinal médian (a) les plus éloignées du manche est de 7 à 13 mm. These guide tufts are 8 to 12 mm long and are arranged symmetrically with respect to a median longitudinal median axis (oc). The distance (a) separating the ends of two symmetric guide tufts with respect to

the median longitudinal axis (a) farthest from the handle is 7 to 13 mm.

La distance (b) séparant les extrémités de deux touffes guides symétriques par rapport à l'axe longitudinal médian (a) les plus proche du manche est de 2 à 5 mm.

The distance (b) separating the ends of two symmetrical guide tufts with respect to the nearest median longitudinal axis (a) of the handle is 2 to 5 mm.

Les touffes guides disposées symétriquement par rapport à l'axe (a) et dont l'écartement entre elles se rétrécit progressivement en allant vers le manche délimitent l'espace guide (E). The guide tufts arranged symmetrically with respect to the axis (a) and whose spacing between them narrows gradually towards the handle delimit the guide space (E).

Le nombre de touffes guides disposées symétriquement par rapport à l'axe (a) doivent permettre de délimiter un espace guide (E) d'une longueur (c) de 15 mm à 25 mm. The number of guide tufts arranged symmetrically with respect to the axis (a) must make it possible to define a guide space (E) of length (c) of 15 mm to 25 mm.

Des touffes plus courtes disposées dans la partie centrale de la surface (B) entre les touffes guides sont destinées aux faces triturantes des dents et sont d'une hauteur comprise entre 5 et 8 mm. Shorter tufts arranged in the central part of the surface (B) between the guide tufts are intended for the triturating faces of the teeth and have a height of between 5 and 8 mm.

Des touffes verticales d'une hauteur égale ou inférieure aux touffes guides peuvent se situer à l'extérieur de l'espace guide délimité par ces touffes guides en particulier si la forme de la surface (B) est rectangulaire FIG (2) ou ovoïde FIG (3) de façon à renforcer l'action des touffes guides . Vertical tufts of a height equal to or less than the guide tufts may lie outside the guide space delimited by these guide tufts, in particular if the shape of the surface (B) is rectangular FIG (2) or ovoid FIG (3) so as to enhance the action of the guide tufts.

Les touffes guide délimitant l'espace guide permettent d'assurer lors d'un mouvement de translation sur l'arcade un brossage complet des trois faces en maintenant un contact étroit des touffes guides sur les zones de rétention de plaque dentaire, malgré des différences anatomiques des dents. The guide tufts delimiting the guide space make it possible to ensure, during a translational movement on the arch, a complete brushing of the three faces while maintaining a close contact of the guide tufts on the areas of retention of dental plaque, despite anatomical differences. teeth.

Le mouvement est guidé par l'implantation spécifique des touffes guides , les dents étant maintenues dans l'espace guide. La différence de hauteur entre les touffes guides et les autres touffes est au minimum de 3 mm. The movement is guided by the specific implantation of the guide tufts, the teeth being held in the guide space. The difference in height between the guide tufts and the other tufts is at least 3 mm.

Cette brosse peut également être mécanisée avec les mêmes formes de tête et surtout les mêmes positions de touffes. This brush can also be mechanized with the same shapes of head and especially the same positions of tufts.

Les mouvements initiés par le mécanisme seront une translation de va et vient sur le plan horizontal et d'une rotation de va et vient par rapport à un axe central de la tête. The movements initiated by the mechanism will be a translation back and forth on the horizontal plane and a rotation back and forth relative to a central axis of the head.

Plusieurs tailles de brosses en fonction de l'âge des utilisateurs seront réalisées.Several brush sizes depending on the age of the users will be realized.
