Definitions
- the present invention relates to a toothbrush comprising a handle for educating the user by encouraging him to perform a proper brushing of his teeth.
- toothbrushes such as, for example, that described in the patent application CN 1 084 723 , are generally poorly suited to the implementation of brushing techniques recommended by oral health professionals to obtain the best possible brushing.
- step of brushing the external faces of the teeth is essential because it makes it possible to free out at the best of the gums deposits and bacteria found in the inter-dental spaces and under the gums, said deposits not or poorly evacuated with high risk of cavities.
- a toothbrush such as that described in the patent application FR 2 786 676 , comprising a handle comprising successively, from front to rear, an end or anterior head carrying, on its lower face, the bristles of the brush extending downwards, an intermediate part and a posterior end part, its intermediate part having a cross-section comprising an upwardly pointed top elemental section and a curved downwardly convexly curved lower elementary section.
- This type of brush facilitates the cleaning of the outer faces of the teeth by oscillating his head.
- its handle is placed in a hand of the user so that the edge of the triangular upper part comes to be placed in the inter-phalangeal space distal of the indexes, major and annular of said hand and that the lower part convex surface comes in contact with the thumb.
- the user By performing simultaneous movements in opposite directions, indexes, major and annular and thumb, the user causes oscillations of the handle, the indexes, major and annular alternately receiving the two planar faces of the upper triangular, while the thumb, always in contact with the convex surface, rolls the brush.
- This type of brush is certainly effective, but it can, without any problem, be used in a conventional manner, namely without oscillation.
- the present invention therefore aims to provide an alternative to the known toothbrush, whose handle has a shape particularly suitable for the production of oscillations, allowing, on the one hand, to perform a proper brushing teeth and, d on the other hand, to educate the user by encouraging him to brush his teeth properly.
- the toothbrush according to the invention comprises a handle successively comprising, from front to rear, an anterior portion constituting a head carrying, on its lower face, downwardly extending bristles, an intermediate portion and a posterior portion, said intermediate portion having a cross-section comprising an upper triangular shaped section with an upwardly directed tip having at least two inclined faces intersecting along an upper edge and a lower elementary section delimited by a convexly oriented arc facing downwards.
- each of the inclined plane faces comprises indicating means able to indicate the direction in which the handle must be oscillated according to its angular orientation, said indication means being at least one hologram comprising at least one pattern and / or character able to animate visually and / or change appearance according to the inclination of the handle.
- the indication means are preferably at least one dynamic image in relief comprising at least one pattern and / or character able to animate visually and / or change appearance according to the inclination of the handle.
- each dynamic image in relief is of the hologram type.
- the intermediate portion is such that its longitudinal section, situated in the vertical plane containing the ridge, comprises a lower elementary section which is delimited by a downwardly convex arc, the curvature of said arc being such that its lower point I does not belong to the plane P defined by the free end of each of the hairs.
- the angle between said inclined plane faces is preferably 45 °.
- the head has a convex upper face.
- anterior end portion preferably comprises a neck connecting said head to the intermediate portion, said neck being narrower than said head and intermediate portion.
- the edge has a curvature with convexity facing upwards.
- the bristles are preferably flexible medium or flexible.
- the toothbrush 1 comprises a handle 2 consisting of three parts having distinct characteristics, namely an anterior end portion 21, an intermediate portion 22 and a posterior end portion 23.
- the front end portion 21 constitutes the head 3 of the brush 1 toothbrush which bears the bristles 4, commonly known as silk, extending perpendicularly downwardly from the lower surface 3a of the head 3 (see figure 1 ), Said lower surface being generally planar 3a as in the case of brushes with current teeth.
- This head 3 further comprises an upper face 3 b curved to fit the inside of the cheek of the user to reduce the pressure exerted on it by said cheek to limit crushing of the bristles 4 and friction and therefore to promote oscillation movements of the head 3 on the teeth.
- the anterior end portion 21 also comprises a neck 5 connecting said head 3 to the intermediate portion 22.
- Said neck 5 is advantageously narrower than the head 3 and intermediate portion 22 of the toothbrush 1 to reach more easily molars and premolars of the user.
- the intermediate portion 22 of the toothbrush 1 is the essential part of it in that its shape facilitates the oscillating movements of the toothbrush 1, as will be explained below. More particularly, the intermediate portion 22 of the brush 1 to teeth preferably includes an upper elementary section in the general shape of a dihedron, comprising two inclined faces 22 a, 22 b intersecting along an upper edge 22 c (see figure 2 ).
- this upper part has an elementary cross-section having an overall inverted V shape, that is to say having its point directed upwards.
- bottom refers to the direction in which the bristles 4 of the toothbrush 1 extend and “high” in the opposite direction.
- the angle between said inclined flat faces 22 a, 22 b is preferably equal to 45 °, to permit brushing the gums by small movements by positioning, instantly and naturally when gripping the handle in inter-phalangeal commissures of the hand, the bristles of the brush 1 at the level of the gingival groove at an angle of 45 ° with respect to the external surface of the teeth according to one of the steps of the STILLMANN method described above. Said positioning is always retained regardless of the grip of the toothbrush 1: the palm or the pen, or the type of the user: male or female, left or right handed, child or adult, seeing or not, young or old.
- the cross section of the intermediate portion 22 is variable along the length of the handle from a minimum value at both ends to a maximum value in the middle portion.
- the edge 22c of the dihedron is thus gradually connected to the anterior portion 21 and posterior 23 of the handle.
- the cross section of the intermediate portion 22 also comprises a lower elementary portion which is delimited by an arc 22 d with convexity facing downwards. This arc defines a convex surface extending along the intermediate portion 22.
- the arc 22 d may be an arc of a circle centered on the vertex or on the edge 22c , that is to say that its radius of curvature can be equal to the width of the inclined plane faces 22 a, 22 b or alternatively the radius of curvature may be slightly different from such a circular arc (see figure 2 ).
- the intermediate and posterior end portions 22 have their entire length, on the one hand, an upper part having an elementary cross-section in the overall form of inverted V and, on the other hand, a lower elementary part delimited by a convexly curved arc facing downwards.
- the edge 22c of the dihedral preferably has a curvature with convexity facing upwards (Cf. figure 3 ).
- the longitudinal section of the intermediate portion 22, located in the vertical plane containing the edge 22c also comprises a lower elementary section which is delimited by a bow 22 e convexity facing downwards.
- the curvature of said arc 22 e is such that its lower point I is situated above or below the plane P defined by the free end of each of the bristles 4 (cf. figure 3 ).
- This feature prevents any bacterial contact contamination of the bristles 3 of the toothbrush 1 on a flat surface and contributes to the proper brushing of the teeth avoiding any unwanted bacterial transmission within the mouth of the user.
- each of the planar inclined faces 22 a, 22 b comprises indication means adapted to indicate the direction in which the handle 2 is to be oscillated in function of the angular orientation of said handle 2.
- said indication means are at least one dynamic relief image 6, advantageously of the hologram type, comprising patterns and / or characters that become animated visually and / or change in appearance according to the inclination of the handle 2 of the brush 1 to teeth, according to the invention, to encourage its user to perform a cleaning of the lateral faces of the teeth by oscillation of the head 3 of said brush 1.
- the user grasps the handle 2 in his right hand, for example, in accordance with Figures 6A, 6B , that is to say by placing, on the one hand, the edge 22c of the intermediate portion 22 of said handle 2 in the inter-phalangeal space distal of its indexes, major, annular and auricular and, d on the other hand, the lower part of the convex surface 22 d of said intermediate portion 22 resting on its thumb.
- the user can, if he wishes, perform simultaneous movements in the opposite direction of his fingers, in order to cause oscillations of the handle 2, his indexes, major, annular and auricular alternately receiving the two inclined plane faces 22 a , 22 b of the intermediate portion 22, while his thumb always in contact with the convex surface 22 d , rolls the brush 1.
- This reciprocating movement of the handle 2 of the toothbrush 1 2 allows a scan of the hair 4 of the gum to the tooth avoiding the twist of the wrist of the user, which is difficult to memorize by young users and hardly applicable in the elderly.
- patterns and / or characters of the dynamic images in relief 6 covering the inclined flat faces 22 a, 22 b of the handle 2 will visually animate and / or change in appearance to indicate to the user to brush 1 teeth according to the invention the direction in which it is to oscillate the handle 2 for optimal effector brushing teeth, said user being positioned in front of a mirror from which to view said inclined plane faces 22 a, 22 b of the handle 2.
- the posterior end portion 23 is advantageously curved upwards, so as to prevent slipping of the toothbrush 1 between the fingers, during this oscillation movement.
- the bristles 4 of the toothbrush 1 according to the invention will preferably be medium or flexible flexibility to promote oscillations of said brush 1 and prevent gum injury by friction.
- each of the planar inclined faces 22 a, 22 b may receive educational, recreational or advertising representations, and / or at least one code in at least two dimensions of the flashcode type QR code or the like referring, for example, a website presenting the modified STILLMANN method.

Description
La présente invention concerne une brosse à dents comprenant un manche permettant d'éduquer l'utilisateur en l'incitant à effectuer un brossage correct de ses dents.The present invention relates to a toothbrush comprising a handle for educating the user by encouraging him to perform a proper brushing of his teeth.
Les brosses à dents utilisées couramment telles que, par exemple, celle décrites dans la demande de brevet
Parmi les diverses méthodes de brossage qui ont été conseillées, celle dite de STILLMANN modifiée préconise de brosser les dents selon au moins les étapes suivantes :
- brosser la surface masticatoire des dents par un mouvement d'avant en arrière,
- positionner les poils de la brosse au niveau du sillon gingivo-dentaire selon un angle de 45° par rapport à la surface externe des dents,
- brosser les dents au niveau des gencives par des petits mouvements circulaire,
- brosser la surface externe des dents en allant de la gencive vers la dent par un mouvement oscillatoire de rouleau.
- brush the masticatory surface of the teeth by moving back and forth,
- position the bristles of the brush at the level of the gingival groove at an angle of 45 ° with respect to the external surface of the teeth,
- brush your teeth at the gums by small circular movements,
- brush the outer surface of the teeth going from the gum to the tooth by an oscillatory movement of the roller.
On comprend bien que l'étape de brossage des faces externes des dents est essentielle car elle permet de dégager au mieux vers l'extérieur des gencives les dépôts et les bactéries se trouvant dans les espaces inter dentaires et sous les gencives, lesdits dépôts non ou mal évacués représentant un risque élevé de caries.It is well understood that the step of brushing the external faces of the teeth is essential because it makes it possible to free out at the best of the gums deposits and bacteria found in the inter-dental spaces and under the gums, said deposits not or poorly evacuated with high risk of cavities.
Pour pallier cet inconvénient, on connait déjà une brosse à dents, telle que celle décrite dans la demande de brevet
Ce type de brosse permet de faciliter le nettoyage des faces externes des dents en faisant osciller sa tête. Pour cela, on place son manche dans une main de l'utilisateur de sorte que l'arête de la partie supérieure triangulaire vienne se placer dans l'espace inter-phalangien distal des index, majeur et annulaire de ladite main et que la partie inférieure à surface convexe vienne en contact avec le pouce. En effectuant des mouvements simultanés, en sens inverse, des index, majeur et annulaire et du pouce, l'utilisateur provoque des oscillations du manche, les index, majeur et annulaire recevant alternativement les deux faces planes de la partie supérieure triangulaire, tandis que le pouce, toujours en contact avec la surface convexe, fait rouler la brosse.This type of brush facilitates the cleaning of the outer faces of the teeth by oscillating his head. For this purpose, its handle is placed in a hand of the user so that the edge of the triangular upper part comes to be placed in the inter-phalangeal space distal of the indexes, major and annular of said hand and that the lower part convex surface comes in contact with the thumb. By performing simultaneous movements in opposite directions, indexes, major and annular and thumb, the user causes oscillations of the handle, the indexes, major and annular alternately receiving the two planar faces of the upper triangular, while the thumb, always in contact with the convex surface, rolls the brush.
Ce type de brosse est certes efficace, mais elle peut, sans aucun problème, être utilisée de manière classique, à savoir sans oscillation.This type of brush is certainly effective, but it can, without any problem, be used in a conventional manner, namely without oscillation.
La présente invention a donc pour but de proposer une alternative à la brosse à dents connue, dont le manche a une forme convenant tout particulièrement à la production des oscillations, permettant, d'une part, de réaliser un brossage correct des dents et, d'autre part, d'éduquer l'utilisateur en l'incitant à effectuer un brossage correct de ses dents.The present invention therefore aims to provide an alternative to the known toothbrush, whose handle has a shape particularly suitable for the production of oscillations, allowing, on the one hand, to perform a proper brushing teeth and, d on the other hand, to educate the user by encouraging him to brush his teeth properly.
A cet égard, la brosse à dents selon l'invention comprend un manche comportant successivement, de l'avant vers l'arrière, une partie antérieure constituant une tête portant, sur sa face inférieure, des poils s'étendant vers le bas, une partie intermédiaire et une partie postérieure, ladite partie intermédiaire ayant une section transversale comprenant une section élémentaire supérieure de forme triangulaire à pointe dirigée vers le haut comportant aux moins deux faces inclinées se recoupant le long d'une arête supérieure et une section élémentaire inférieure délimitée par un arc à convexité tournée vers le bas. Ladite brosse à dents est remarquable en ce que chacune des faces planes inclinées comporte des moyens d'indication aptes à indiquer la direction dans laquelle le manche doit être oscillé en fonction de son orientation angulaire, lesdits moyens d'indication étant au moins un hologramme comportant au moins un motif et/ou caractère apte à s'animer visuellement et/ou changer d'apparence selon l'inclinaison du manche.In this respect, the toothbrush according to the invention comprises a handle successively comprising, from front to rear, an anterior portion constituting a head carrying, on its lower face, downwardly extending bristles, an intermediate portion and a posterior portion, said intermediate portion having a cross-section comprising an upper triangular shaped section with an upwardly directed tip having at least two inclined faces intersecting along an upper edge and a lower elementary section delimited by a convexly oriented arc facing downwards. Said toothbrush is remarkable in that each of the inclined plane faces comprises indicating means able to indicate the direction in which the handle must be oscillated according to its angular orientation, said indication means being at least one hologram comprising at least one pattern and / or character able to animate visually and / or change appearance according to the inclination of the handle.
Les moyens d'indication sont de préférence au moins une image dynamique en relief comportant au moins un motif et/ou caractère apte à s'animer visuellement et/ou changer d'apparence selon l'inclinaison du manche.The indication means are preferably at least one dynamic image in relief comprising at least one pattern and / or character able to animate visually and / or change appearance according to the inclination of the handle.
Selon un mode de réalisation préféré, chaque image dynamique en relief, est du type hologramme.According to a preferred embodiment, each dynamic image in relief, is of the hologram type.
De manière avantageuse, la partie intermédiaire est telle que sa section longitudinale, située dans le plan vertical contenant l'arête, comprend une section élémentaire inférieure qui est délimitée par un arc à convexité tournée vers le bas, la courbure dudit arc étant telle que son point inférieur I n'appartient pas au plan P défini par l'extrémité libre de chacun des poils.Advantageously, the intermediate portion is such that its longitudinal section, situated in the vertical plane containing the ridge, comprises a lower elementary section which is delimited by a downwardly convex arc, the curvature of said arc being such that its lower point I does not belong to the plane P defined by the free end of each of the hairs.
En outre, l'angle entre lesdites faces planes inclinées est de préférence égal à 45°.In addition, the angle between said inclined plane faces is preferably 45 °.
De manière avantageuse, la tête comporte une face supérieure bombée.Advantageously, the head has a convex upper face.
En outre, la partie extrême antérieure comporte de préférence un col reliant ladite tête à la partie intermédiaire, ledit col étant plus étroit que lesdites tête et partie intermédiaire.In addition, the anterior end portion preferably comprises a neck connecting said head to the intermediate portion, said neck being narrower than said head and intermediate portion.
Par ailleurs, l'arête présente une courbure à convexité tournée vers le haut.In addition, the edge has a curvature with convexity facing upwards.
Enfin, les poils sont de préférence de souplesse médium ou souple.Finally, the bristles are preferably flexible medium or flexible.

En référence aux
La partie extrême antérieure 21 constitue la tête 3 de la brosse 1 à dents qui porte ses poils 4, communément appelés soie, s'étendant perpendiculairement vers le bas à partir de la surface inférieure 3a de la tête 3 (Cf.
Cette tête 3 comporte en outre une face supérieure 3b bombée de manière à épouser l'intérieur de la joue de l'utilisateur pour réduire la pression exercée sur elle par ladite joue afin de limiter l'écrasement des poils 4 et les frottements et donc de favoriser les mouvements d'oscillation de la tête 3 sur les dents.This
Par ailleurs, la partie extrême antérieure 21 comporte également un col 5 reliant ladite tête 3 à la partie intermédiaire 22. Ledit col 5 est avantageusement plus étroit que les tête 3 et partie intermédiaire 22 de la brosse 1 à dents de sorte à atteindre plus facilement molaires et prémolaires de l'utilisateur.Furthermore, the
La partie intermédiaire 22 de la brosse 1 à dents est la partie essentielle de celle-ci en ce que sa forme facilite les mouvements d'oscillation de la brosse 1 à dents, comme il sera précisé plus loin. Plus particulièrement, la partie intermédiaire 22 de la brosse 1 à dents comporte de préférence une partie élémentaire supérieure en forme générale de dièdre, constituée de deux faces inclinées 22a, 22b se recoupant le long d'une arête supérieure 22c (Cf.
Autrement dit, cette partie supérieure présente une section transversale élémentaire ayant une forme globale de V inversé, c'est-à-dire ayant sa pointe dirigée vers le haut.In other words, this upper part has an elementary cross-section having an overall inverted V shape, that is to say having its point directed upwards.
On désigne ici par "bas" la direction dans laquelle les poils 4 de la brosse 1 à dents s'étendent et par "haut" la direction opposée.The term "bottom" refers to the direction in which the
On comprend bien que lesdites faces inclinées 22a, 22b sont de préférence planes. Toutefois, elles pourront être non planes et être, par exemple, au moins en partie incurvées, bombées ou encore crénelées, sans sortir du cadre de la présente invention.Said inclined surfaces is well understood that 22 a, 22 b are preferably flat. However, they may be non-planar and be, for example, at least partly curved, curved or crenellated, without departing from the scope of the present invention.
L'angle entre lesdites faces planes inclinées 22a, 22b est de préférence égal à 45°, afin de permettre un brossage des dents au niveau des gencives par des petits mouvements en positionnant, instantanément et naturellement lors de la préhension du manche dans les commissures inter-phalangiennes de la main, les poils de la brosse 1 au niveau du sillon gingivo-dentaire selon un angle de 45° par rapport à la surface externe des dents conformément à l'une des étapes de la méthode de STILLMANN précédemment décrite. Ledit positionnement est toujours conservé quelle que soit la prise en main de la brosse 1 à dents : à la paume ou au stylo, ou le type de l'utilisateur : homme ou femme, gaucher ou droitier, enfant ou adulte, voyant ou non, jeune ou vieux.The angle between said inclined
La section transversale de la partie intermédiaire 22 est variable suivant la longueur du manche en partant d'une valeur minimale aux deux extrémités jusqu'à une valeur maximale dans la partie médiane. L'arête 22c du dièdre se raccorde ainsi progressivement aux parties antérieure 21 et postérieure 23 du manche. La section transversale de la partie intermédiaire 22 comprend également une partie élémentaire inférieure qui est délimitée par un arc 22d à convexité tournée vers le bas. Cet arc définit une surface convexe s'étendant le long de la partie intermédiaire 22. L'arc 22d peut être un arc de cercle centré sur le sommet ou sur l'arête 22c, c'est-à-dire que son rayon de courbure peut être égal à la largeur des faces planes inclinées 22a, 22b ou bien encore le rayon de courbure peut être légèrement différent d'un tel arc de cercle (Cf.
Selon un mode avantageux, les parties intermédiaire 22 et extrême postérieure 23 comportent sur toute leur longueur, d'une part, une partie supérieure présentant une section transversale élémentaire en forme globale de V inversé et, d'autre part, une partie élémentaire inférieure délimitée par un arc à convexité tournée vers le bas.According to an advantageous embodiment, the intermediate and
En outre, pour permettre une adaptation parfaite du manche 2 de la brosse 1 à dents à la morphologie de la main de l'utilisateur, l'arête 22c du dièdre présente de préférence une courbure à convexité tournée vers le haut (Cf.
Par ailleurs, la section longitudinale de la partie intermédiaire 22, située dans le plan vertical contenant l'arête 22c, comprend également une section élémentaire inférieure qui est délimitée par un arc 22e à convexité tournée vers le bas. La courbure dudit arc 22e est telle que son point inférieur I est situé au-dessus ou en-dessous du plan P défini par l'extrémité libre de chacun des poils 4 (Cf.
Cette caractéristique empêche toute contamination bactérienne par contact des poils 3 de la brosse 1 à dents sur une surface plane et contribue au brossage correct des dents en évitant toute transmission bactérienne indésirable à l'intérieur de la bouche de l'utilisateur.This feature prevents any bacterial contact contamination of the
Suivant une caractéristique essentielle de la présente invention, chacune des faces planes inclinées 22a, 22b comporte des moyens d'indication aptes à indiquer la direction dans laquelle le manche 2 doit être oscillé en fonction de l'orientation angulaire dudit manche 2. Selon un mode préféré de réalisation représenté à la
Ainsi, pour effectuer un nettoyage des faces latérales des dents par oscillation de la tête 3 de la brosse 1, l'utilisateur saisit le manche 2 dans sa main droite par exemple, conformément aux
Ensuite, comme il est indiqué par les flèches sur les
Afin d'inciter l'utilisateur à effectuer ces oscillations, les motifs et/ou caractères des images dynamiques en relief 6 recouvrant les faces planes inclinées 22a, 22b du manche 2 vont s'animer visuellement et/ou changer d'apparence pour indiquer à l'utilisateur de la brosse 1 à dents selon l'invention la direction dans laquelle il doit osciller le manche 2 pour effecteur un brossage de dents optimal, ledit utilisateur étant positionné devant un miroir lui permettant de voir lesdites faces planes inclinées 22a, 22b du manche 2.In order to encourage the user to perform these oscillations, patterns and / or characters of the dynamic images in relief 6 covering the inclined flat faces 22 a, 22 b of the
Ainsi, lorsque le manche 2 est dans la position représentée sur la
Ainsi, en regardant dans le miroir les images dynamiques en relief 6 recouvrant les faces planes inclinées 22a, 22b du manche 2, l'utilisateur sera donc incité de façon visuelle voire ludique à produire des oscillations de la brosse 1 à dents afin d'effectuer un brossage correct de ses dents pour l'application des techniques de brossage recommandées.Thus, looking into the mirror dynamic images in relief 6 covering the inclined flat faces 22 a, 22 b of the
Suivant une caractéristique complémentaire de la présente invention, la partie extrême postérieure 23 est avantageusement incurvée vers le haut, de sorte à éviter tout glissement de la brosse 1 à dents entre les doigts, au cours de ce mouvement d'oscillation.According to a complementary feature of the present invention, the
On comprend également bien que les poils 4 de la brosse 1 à dents selon l'invention seront de préférence de souplesse médium ou souple pour favoriser les oscillations de ladite brosse 1 et éviter toute blessure par frottement des gencives.It is also understood that the
Enfin, chacune des faces planes inclinées 22a, 22b pourra recevoir des représentations éducatives, ludiques ou encore publicitaires, et/ou au moins un code à au moins deux dimensions du type flashcode, QR code ou similaire renvoyant, par exemple, à un site internet présentant la méthode dite de STILLMANN modifiée.Finally, each of the planar inclined faces 22 a, 22 b may receive educational, recreational or advertising representations, and / or at least one code in at least two dimensions of the flashcode type QR code or the like referring, for example, a website presenting the modified STILLMANN method.
On comprend bien que la brosse 1 à dents, selon l'invention, s'applique tout particulièrement au brossage des dents d'un humain.It is well understood that the
Enfin, il est clair que la présente invention ne se limite pas à la seule forme d'exécution de cette brosse 1 à dents ; elle en embrasse, au contraire, toutes les variantes de réalisation et d'application respectant le même principe.Finally, it is clear that the present invention is not limited to the sole embodiment of this
