Description

La présente invention concerne une brosse à dents dite transversale selon le préambule des revendications 1 et 5 et à manche de préhension à la main ou de fixation sur une machine à moteur pour assurer respectivement le brossage manuel ou mécanique des dents avec une efficacité améliorée.The present invention relates to a so-called transverse toothbrush according to the preamble of claims 1 and 5 and with grip handle by hand or fixing on a motorized machine to ensure manual or mechanical brushing of the teeth with improved efficiency.

La brosse à dents selon l'invention se compose d'un corps de brosse sensiblement rectangulaire avec un manche de direction sensiblement inclinée, de préférence perpendiculaire par rapport à la direction longitudinale du corps de brosse. Cette nouvelle configuration bien que semblant à première vue mal fonctionner car n'atteignant pas les dents du fond, permet un brossage efficace car elle favorise un brossage transversal consistant en un déplacement transversal de haut en bas perpendiculaire aux rangées de dents et parallèle aux dents et à leur implantation.The toothbrush according to the invention consists of a brush body substantially rectangular with a substantially inclined steering stick, preferably perpendicular relative to the longitudinal direction of the brush body. This new configuration although seemingly malfunctioning at first sight because it does not reach the back teeth, allows effective brushing because it promotes a transverse brushing consisting of a displacement transverse from top to bottom perpendicular to the rows of teeth and parallel to the teeth and their implantation.

Ce brossage « dit transversal » nettoie les parties proéminentes mais également les interstices et les parties en retrait des dents où les déchets ont tendance à rester coincé et à s'accumuler. Il permet également d'exercer une meilleure action de massage sur la hauteur des gencives avec une grande efficacité au niveau du collet de la dent pour en éliminer le tartre. Cette tenue du manche est la seule qui permet un mouvement naturel, aisé de va et vient vertical. Pour les enfants la tenue de cette brosse dont le manche est différent devient un jeu en ayant une meilleure hygiène. Des études entreprises ont permis de constater que les personnes handicapées ont plus de facilité à faire le mouvement de haut en bas que celui de poussées et tractions horizontales.This “transverse” brushing cleans the prominent parts but also the interstices and recessed parts of the teeth where the waste tends to get stuck and accumulate. It also allows to exert a better massage action on the height of the gums with great efficiency at the level of the tooth neck to remove tartar. This holding of the handle is the only one that allows a natural movement, easy back and forth vertical. For children holding this brush with a different handle becomes a game in having better hygiene. Studies have shown that people disabled have an easier time moving up and down than pushing and horizontal pull-ups.

Plusieurs modèles de brosses à dents permettent de brosser les dents de haut en bas en ayant la forme d'un T majuscule ; le corps de brosse occupant la branche supérieure horizontale et le manche la tige verticale du T.Several models of toothbrushes can brush your teeth from top to bottom having the form of a capital T; the brush body occupying the upper branch horizontal and the handle the vertical rod of the T.

Certains modèles sont fixes, tels ceux décrits dans les documents DE-A-3228946 et FR-A-2 583 963. Ce premier document décrit un corps de brosse droit ou bien courbe afin de tenir compte de la concavité de la mâchoire. Le document FR-A-2 583 963 montre une brosse où son orientation se fait par déformation du manche qui doit être fabriqué en un matériau aux propriétés mécanique appropriées ou bien en une matière plastique souple moulée sur un insert métallique. Ces deux documents ne font pas ressortir qu'un tiers environ du manche en partant du corps de brosse doit présenter une courbe concave par rapport au visage lorsque la brosse est en position de nettoyage.Some models are fixed, such as those described in documents DE-A-3228946 and FR-A-2 583 963. This first document describes a straight or curved brush body in order to take into account the concavity of the jaw. Document FR-A-2 583 963 shows a brush where its orientation is by deformation of the handle which must be made of a material with suitable mechanical properties or a flexible plastic molded on an insert metallic. These two documents do not show that about a third of the handle when leaving of the brush body must have a concave curve relative to the face when the brush is in the cleaning position.

Dans les documents US-A-2084873 et US-A-5315730, il est décrit des brosses à dents à tête transversale fixe avec des manches plus ou moins courbes. Ce premier document montre un manche dont la configuration est en forme de « S » et où l'utilisation de la tête (4) est impossible car le manche après la tête comporte une courbure inverse à l'utilisation d'un brossage transversal. En effet, dans ce cas le manche heurte en permanence le menton et la mâchoire inférieure. De même le document US-A-5315730 possède un manche constitué de deux parties droites (11) et (17) faisant un angle de l'ordre de 150° entres elles et dont le plan de la brosse perpendiculaire à la direction des poils fait un angle de 3° à 7° avec la partie adjacente du manche. Une telle brosse est difficile à utiliser puisque le manche butte le menton au cours du brossage.In documents US-A-2084873 and US-A-5315730, brushes are described. teeth with fixed transverse head with more or less curved handles. This first document shows a handle with an "S" shaped configuration and where the use of the head (4) is impossible because the handle after the head has a reverse curvature when using a transverse brushing. Indeed, in this case the handle permanently hits the chin and the lower jaw. Likewise, document US-A-5315730 has a handle consisting of two straight parts (11) and (17) making an angle of the order of 150 ° between them and whose plane of the brush perpendicular to the direction of the bristles makes an angle of 3 ° to 7 ° with the part adjacent to the handle. Such a brush is difficult to use since the handle abuts the chin during brushing.

Il est connu du document patent abstracts of Japan vol. 096, N°004, du 30 avril 1996 § JP-A-07 3132251 , une brosse à dents dont le manche est essentiellement rectiligne et dont seules les extrémités des poils de la brosse dépassent de la projection verticale de la section du manche.It is known from the document patent abstracts of Japan vol. 096, N ° 004, of April 30, 1996 § JP-A-07 3132251, a toothbrush whose handle is essentially straight and whose only the ends of the bristles of the brush protrude from the vertical projection of the section of the handle.

Les informations de ces documents ne font que poser le problème de ce que doit être l'invention géométrique dont la définition précise n'est pas évidente pour l'homme du métier . La solution aux problèmes d'un tel type de brosse n'est pas indiqué pour en résoudre les questions techniques.The information in these documents only poses the problem of what should be the geometric invention, the precise definition of which is not obvious to a person skilled in the art. The solution to the problems of such a type of brush is not indicated to resolve them. technical issues.

Dans le document WO-A-95/01113, le maintien angulaire est obtenu par un goujon en forme de champignon à lamelles longitudinales qui s'engage dans une cavité du manche. Les lamelles évitent le décrochement de la brosse de la cavité du manche. Dans les documents DE-A-2427877 et FR-A-2 583 963 le blocage en rotation s'effectue seulement dans deux positions, l'une longitudinale, l'autre transversale. Ces trois documents ne tiennent pas compte de la courbure du manche afin de rendre possible le brossage transversal sans heurter le menton. Les nombreuses surfaces non étanches des systèmes de rotations sont autant de niches à détritus et à bactéries, réintroduits dans la bouche à la prochaine utilisation de la brosse. Le dentifrice pouvant pénétrer entre ces surfaces et y durcir peut bloquer le système et augmente considérablement l'usure des pièces en friction, donc la durée de vie de l'ensemble. Le document FR-A-2 583 963 fig. 1, 5, 7, et le document DE-A-24 27 877 fig 3, 4, 5, montrent un manche dont la partie concave correspond uniquement à la longueur de dégagement de rotation du corps de brosse, ce qui est nettement insuffisant pour dégager le menton. Le profil du manche du document GB-A-2101476 est totalement inopérationnel étant donné que la naissance du manche butte contre les lèvres et gêne le brossage.In document WO-A-95/01113, the angular support is obtained by a stud in mushroom shape with longitudinal lamellae which engages in a cavity in the handle. The slats prevent the brush from detaching from the handle cavity. In the documents DE-A-2427877 and FR-A-2 583 963 the blocking in rotation is carried out only in two positions, one longitudinal, the other transverse. These three documents do not take into account of the curvature of the handle in order to make possible the transverse brushing without hitting the chin. The many non-sealed surfaces of the rotation systems are as many litter and bacteria kennels, reintroduced into the mouth the next time the brush. Toothpaste that can penetrate and harden between these surfaces can block the system and considerably increases the wear of the friction parts, therefore the service life of all. The document FR-A-2 583 963 fig. 1, 5, 7, and document DE-A-24 27 877 fig 3, 4, 5, show a handle whose concave part corresponds only to the length of clearance for rotation of the brush body, which is clearly insufficient to release the chin. The handle profile of document GB-A-2101476 is completely inoperative being given that the birth of the handle abuts against the lips and hinders brushing.

Le document EP-A-0 077 869 montre une brosse à deux positions transversales et deux positions longitudinales où l'extrémité du manche en forme de queue mâle se glisse dans les queues d'aronde femelle du corps de brosse . Le blocage en position est obtenu par un système de billes et de ressort placés dans le corps de brosse. Ce document ne tient pas compte du galbe nécessaire du manche pour permettre le passage du menton. Ce système présente aussi l'inconvénient que le blocage en position n'est pas définitif et que le corps de brosse peut se désolidariser du manche dans la bouche et qu'il peut être avaler ou causer un accident plus grave par obstruction des voies respiratoires supérieures.Document EP-A-0 077 869 shows a brush with two transverse positions and two longitudinal positions where the end of the handle in the shape of a male tail slides into the female dovetails of the brush body. Locking in position is obtained by a ball and spring system placed in the brush body. This document does not hold account of the necessary curve of the handle to allow the passage of the chin. This system also has the disadvantage that the locking in position is not final and that the body of brush may detach from the handle in the mouth and it may be swallowing or causing a more serious accident due to obstruction of the upper respiratory tract.

Les manches montrés dans ces antériorités tiennent seulement compte de la rotation du corps de brosse en ignorant complètement le problème posé pour le passage du menton. Dans d'autres modèles, le corps de brosse est monté rotatif sur le manche, pour le ramener dans le prolongement du manche dans un brossage traditionnel des dents d'avant en arrière.The sleeves shown in these prior art only take into account the brush body rotation completely ignoring the problem posed for the passage of the chin. In other models, the brush body is rotatably mounted on the handle, to bring it back in the extension of the handle in a traditional brushing of the teeth from front to back.

Le document US-A-5 499 422 décrit une brosse dont le blocage en position du manche par rapport au corps de brosse s'effectue à l'aide d'une rondelle anti friction pressée par un rivet entre une surface du manche et une surface du corps de brosse. Le document GB-A-2 101 476 montre un système de blocage en position constitué par une forme de « U » renversé présentant un trou circulaire et en regard le dos de la tête présente une cavité. L'extrémité du manche ayant deux tétons vient s'emboíter dans le trou et la cavité. Il est dit que la force élastique du « U » sur la cavité de la tête est suffisante pour maintenir par friction le manche dans la position choisie lors du brossage. Il est de toute évidence que la très faible surface de contact entre les tétons et leurs logements et que la pression du « U » insuffisante compte tenu qu'il doit être très flexible pour changer la tête ne peuvent assurer un maintient ferme en position du manche par rapport à la tête et que les faibles surfaces en friction vont très rapidement s'user et se désajuster. Une autre variante décrit un système de fentes et rainures sur la tête et le manche l'ensemble étant maintenu par la pièce élastique du « U » ici encore la pression du « U » insuffisante compte tenu qu'il doit être très flexible pour changer la tête ne peuvent assurer un maintient ferme en position du manche par rapport à la tête. Il est dit également qu'il existe des moyens de verrouillages adaptés soit que le manche est constitué d'une rainure et de joint à ressort ou de moyens équivalents soit que la tige est avec ressort pour rendre la tête interchangeable. La tête interchangeable implique le risque du détachement et de l'avalement du corps de brosse lors de son utilisation et éventuellement le risque d'un accident plus grave par obstruction des voies respiratoires. L'importante surface entre les deux supports opposés et le mécanisme non protégé constituent une niche à détritus et à bactéries non compatible avec nos règles d'hygiène. Dans le document US-A-4 020 521 la tête de la brosse comporte une projection d'une longueur égale à la hauteur du manche et moulée dans le même temps que la tête. Cette projection comprend sur sa périphérie plusieurs dentelures. Le manche d'une seule pièce côté main comporte un trou pour maintenir un tube de dentifrice. De l'autre coté, le manche a une largeur égale à celle de la tête lorsqu'il est dans l'alignement de la tête. Coté tête, un trou dentelé, traversant de part en part le manche est centré sur la projection de la tête. Les dentelures verticales et parallèles de la projection dont le diamètre est légèrement plus grand que celui du trou coopèrent afin que l'emboítement soit serré. Pour permettre l'emboítement et la rotation du manche par rapport à la tête une fente perpendiculaire à l'axe longitudinale du manche est réalisée de l'extrémité du manche au trou. Dans ce document le mécanisme ne présente aucun moyen, lors de l'utilisation de la brosse pour empêcher le déboítement corps de brosse et manche dans ce cas le risque d'avaler le corps de brosse est important et le risque d'obstruction des voies respiratoires aussi. Le mécanisme ne présente aucune protection pour l'isoler des détritus, bactéries ainsi que du dentifrice. De plus sur la fig. ( 1) il est visible que l'extrémité du manche fendu lorsqu'il est en position transversal fait saillie à l'extérieur du corps de brosse et vient buter sur le haut des gencives rendant impossible l'utilisation de la brosse en position transversale.
La brosse à dents dite transversale est décrite dans la partie caractérisante des revendications 1 et 5.Document US-A-5 499 422 describes a brush whose locking in position of the handle relative to the brush body is effected by means of an anti-friction washer pressed by a rivet between a surface of the handle and a surface of the brush body. Document GB-A-2 101 476 shows a position locking system constituted by an inverted "U" shape having a circular hole and facing the back of the head has a cavity. The end of the handle having two nipples fits into the hole and the cavity. It is said that the elastic force of the "U" on the head cavity is sufficient to frictionally hold the handle in the position chosen during brushing. It is obvious that the very small contact surface between the nipples and their housings and that the pressure of the "U" insufficient considering that it must be very flexible to change the head cannot ensure a firm hold in position of the handle relative to the head and that the low friction surfaces will wear out and adjust very quickly. Another variant describes a system of slots and grooves on the head and the handle, the whole being held by the elastic piece of the "U", here again the pressure of the "U" is insufficient, given that it must be very flexible to change the head cannot provide a firm hold in position of the handle relative to the head. It is also said that there are suitable locking means either that the handle consists of a groove and spring seal or equivalent means or that the rod is with spring to make the head interchangeable. The interchangeable head involves the risk of detachment and swallowing of the brush body during its use and possibly the risk of a more serious accident by obstruction of the respiratory tract. The large surface between the two opposite supports and the unprotected mechanism constitutes a trash and bacteria niche not compatible with our hygiene rules. In document US-A-4,020,521 the head of the brush has a projection of a length equal to the height of the handle and molded at the same time as the head. This projection includes on its periphery several serrations. The one-piece handle on the hand side has a hole to hold a tube of toothpaste. On the other side, the handle has a width equal to that of the head when it is in alignment with the head. On the head side, a serrated hole, going right through the handle is centered on the projection of the head. The vertical and parallel serrations of the projection whose diameter is slightly larger than that of the hole cooperate so that the socket is tight. To allow nesting and rotation of the handle relative to the head a slot perpendicular to the longitudinal axis of the handle is made from the end of the handle to the hole. In this document the mechanism has no means, when using the brush to prevent dislocation of the brush body and handle in this case the risk of swallowing the brush body is important and the risk of obstruction of the respiratory tract also. The mechanism has no protection to isolate it from detritus, bacteria and toothpaste. Also in fig. (1) it is visible that the end of the split handle when in the transverse position protrudes outside the brush body and abuts on the top of the gums making it impossible to use the brush in the transverse position.
The so-called transverse toothbrush is described in the characterizing part of claims 1 and 5.

La brosse suivant l'invention est constituée d'un corps de brosse ( 1 ) de forme allongée rectangulaire de préférence comportant une à quatre rangées longitudinales de trous ( 3 ) pratiqués dans le corps de brosse pour maintenir les poils et d'un manche allongé ( 2 ) perpendiculaire à la direction longitudinale du corps de brosse. Le manche (2 ) est relié directement au corps de brosse ( 1 ) sur un grand coté latéral ( 4) de celui-ci , ou bien sur la face arrière du corps de brosse de façon à ce que le plan de la face avant du corps de brosse ( 1 ) soit dans un plan décalé parallèlement au plan contenant le manche qui présente immédiatement après sa naissance un galbe ( 5 ) permet le dégagement du menton lors de l'utilisation de la brosse. Chacune des deux ailes du corps de brosse disposée de chaque côté du manche (2) a une longueur suffisante pour que les touffes extrêmes de poils atteignent les dents du fond lorsque la naissance du manche est en contact avec la commissure des lèvres. Le manche a été étudié dans sa section qui après sa naissance est de forme ovoïde dont les diamètres sont de 5,5 millimètres par 5 millimètres et présente une courbe ou galbe ( 5 ) régulier d'une hauteur de 6,7 centimètres et d'une profondeur maximum de 10 millimètres par rapport à une ligne reliant les deux extrémités de ce galbe. Il permet ainsi d'après les études entreprises, ceci dans 95% des cas, laisse le passage du menton lorsque la brosse est utilisée dans la position la plus confortable, c'est à dire le coude collé au corps , l'avant bras le poignet et la main dans un même plan très proche de la poitrine afin de réduire au maximum les efforts dus au brossage. Cette position de brossage étant la plus naturelle permet aux poils de la brosse d'être uniformément en contact avec les dents et les gencives dans le but d'une efficacité maximum. Après le premier galbe, le manche présente une courbe inverse de 2° qui prend du volume puisque cette zone est celle qui est tenue par la main son épaisseur va de 14 millimètres à 27 millimètres .L'intérieur du manche dans cette partie plus grosse est alors creux pour une économie de poids et de matière première. La zone de préhension est surmoulée dans un matériau élastique ( 7 ) et comprend 10 demi cercles ( 8 ) pour une meilleure tenue de la brosse. Il se termine par un trépied dont les pointes ( 9 ) sont espacées de 20 millimètres ce qui permet à la brosse de se tenir debout sans appui pour une meilleure hygiène, (fig 1 ).
La brosse à moteur est fixée au manche après la partie galbée nécessaire au dégagement du menton. Les autres exemples de brosse sont pourvus du même manche que celui décrit ci dessus.The brush according to the invention consists of a brush body (1) of elongated rectangular shape preferably comprising one to four longitudinal rows of holes (3) made in the brush body to hold the bristles and of an elongated handle. (2) perpendicular to the longitudinal direction of the brush body. The handle (2) is connected directly to the brush body (1) on a large lateral side (4) thereof, or else on the rear face of the brush body so that the plane of the front face of the brush body (1) either in a plane offset parallel to the plane containing the handle which immediately after its birth a curve (5) allows the chin to be released when the brush is used. Each of the two wings of the brush body arranged on each side of the handle (2) has a length sufficient for the extreme tufts of bristles to reach the back teeth when the birth of the handle is in contact with the corner of the lips. The handle has been studied in its section which after its birth is ovoid in shape, the diameters of which are 5.5 millimeters by 5 millimeters and has a regular curve or curve (5) with a height of 6.7 centimeters and a maximum depth of 10 millimeters in relation to a line connecting the two ends of this curve. It allows thus according to the studies undertaken, this in 95% of the cases, leaves the passage of the chin when the brush is used in the most comfortable position, ie the elbow glued to the body, the forearm the wrist and hand in the same plane very close to the chest in order to minimize the efforts due to brushing. This brushing position being the most natural allows the bristles of the brush to be uniformly in contact with the teeth and gums for the purpose of maximum efficiency. After the first curve, the handle has a reverse curve of 2 ° which takes volume since this area is the one held by the hand its thickness goes from 14 millimeters to 27 millimeters. The interior of the handle in this larger part is so hollow for a saving of weight and raw material. The gripping area is overmolded in an elastic material (7) and includes 10 semi-circles (8) for better grip of the brush. It ends with a tripod whose tips (9) are spaced 20 millimeters apart which allows the brush to stand upright without support for better hygiene, (fig 1).
The motor brush is attached to the handle after the curved part necessary to clear the chin. The other examples of brushes have the same handle as that described above.

Selon un autre exemple de réalisation, le manche ( 2 ) est monté mobile sur le corps de la brosse ( 1) de façon à ce que les axes longitudinaux du manche et du corps de brosse puissent prendre des directions différentes. Cette mobilité permet plusieurs configurations avantageuses de la brosse. La première consiste à transformer la brosse transversale selon l'invention, en une brosse longitudinale où les axes du manche et du corps de brosse sont alignés, le manche pouvant prendre toutes les directions intermédiaires par rapport au corps de brosse que permettent les moyens de fixations et de blocages mécaniques du manche au corps de brosse . Ainsi le corps de brosse, sur son plan médian transversal présente un cône tronqué ( 10) en forme d'engrenage d'un angle de 70° avec 12 dents arrondies en relief (11) de valeur 0,5 et 12 dents en arrondies en creux ( 12 ) de valeur 0,5 . La forme arrondie des dents a été étudiée pour limiter l'usure du mécanisme et pour faciliter l'orientation du manche par déformation élastique des pièces coopérant. Les dents sont équidistantes entre elles. L'angle obtenu entre une dent en relief et la dent suivante en creux est de 15°. Sur la base supérieure du cône tronqué est centré un axe (13) dont la partie supérieure a un rayon de 1,85 millimètre pour une hauteur de 1 millimètre et dont la partie inférieure a un rayon de 1,55 millimètre pour une hauteur de 1 millimètre. Cette partie supérieure de l'axe est appelée lèvre de rétention ( 14 ). Cet ensemble cône plus axe est de même matière que le corps de brosse et moulé dans le même temps. Le manche est prolongé à son extrémité par une cloche ( 15 ) dont la base circulaire a un diamètre de 11,6 millimétres le sommet un diamètre de 5 millimétres la hauteur étant de 4,6 millimètres. Le sommet est alésé (16) au rayon de 1.55 millimètre pour s'enclipser sur l'axe et rendre l'ensemble indémontable.According to another exemplary embodiment, the handle (2) is mounted mobile on the body of the brush (1) so that the longitudinal axes of the handle and the brush body can take different directions. This mobility allows several configurations advantageous of the brush. The first consists in transforming the transverse brush according to the invention, in a longitudinal brush where the axes of the handle and of the brush body are aligned, the handle can take all intermediate directions relative to the body brush that allow the means of mechanical fixing and blocking of the handle to brush body. Thus the brush body, on its transverse median plane has a cone truncated (10) in the form of a gear at an angle of 70 ° with 12 rounded teeth in relief (11) with a value of 0.5 and 12 recessed rounded teeth (12) with a value of 0.5. The rounded shape teeth has been studied to limit the wear of the mechanism and to facilitate the orientation of the handle by elastic deformation of the cooperating parts. Teeth are equidistant between they. The angle obtained between a raised tooth and the next hollow tooth is 15 °. On the upper base of the truncated cone is centered an axis (13) whose upper part has a radius of 1.85 millimeters for a height of 1 millimeter and the lower part has a radius of 1.55 millimeters for a height of 1 millimeter. This part upper axis is called retention lip (14). This cone plus axis assembly is same material as the brush body and molded at the same time. The handle is extended at its end by a bell (15) whose circular base has a diameter of 11.6 millimeters the top a diameter of 5 millimeters, the height being 4.6 millimeters. The summit is bored (16) with a radius of 1.55 millimeter to snap onto the axis and make the assembly cannot be dismantled.

Selon une première variante, à l'intérieur de la cloche (fig 3b) et à sa partie supérieure, face à l'extrémité du manche se trouvent deux dents ( 17 ) arrondies à 0 5, pour le blocage en position de l'ensemble manche, cloche et corps de brosse. Sur la partie interne de ia cloche et sur toute sa hauteur se trouve une partie de cylindre conique (18) en regard des dents en relief du corps de brosse dans le but de centrer et d'assurer le blocage en position du manche. Le passage d'une dent à une autre est possible grâce à élasticité des pieces coopérant. L'étanchéité pour la partie supérieure de la cloche est assurée par le diamètre de l'axe identique à celui de l'alésage de la cloche . L'étancheité inférieure est assurée par une rampe circulaire en creux (19) dans le corps de brosse et par la base de la cloche (20) qui vient s'y loger.According to a first variant, inside the bell (fig 3b) and at its upper part, opposite the end of the handle are two teeth (17) rounded to 0 5, for locking in position of the handle, bell and brush body assembly. On the internal part of ia bell and over its entire height is a portion of conical cylinder (18) opposite the teeth in relief of the brush body in order to center and ensure the locking in position of the handle. The transition from one tooth to another is possible thanks to the elasticity of the pieces cooperating. The tightness for the upper part of the bell is ensured by the diameter of the axis identical to that of the bore of the bell. The lower seal is ensured by a circular recessed ramp (19) in the brush body and by the base of the bell (20) which comes to stay there.

Selon une deuxieme variante se trouvent à l'intérieur de la cloche (fig 3a) trois parties de cylindre ( 21 ) équidistante les unes des autres pour venir en contact avec les dents en relief et ainsi assurer le centrage de l'ensemble. Le blocage en position est permis grace à un linguet ( 22 ) faisant office de dent et coopérant avec les dents du cône du corps de brosse. Le changement de position du manche est permis dans l'élasticité des pièces coopérant.According to a second variant are located inside the bell (fig 3a) three cylinder parts (21) equidistant from each other to come into contact with the teeth in relief and thus ensure the centering of the assembly. Locking in position is allowed thanks to a latch (22) acting as a tooth and cooperating with the teeth of the cone of the body brush. The position of the handle can be changed in the elasticity of the pieces cooperating.

Selon un autre exemple de réalisation, sensiblement sur le plan median transversal du corps de brosse (fig 2b) se trouve un cône tronqué de surface lisse (23) surmonte du même type d'axe que celui décrit où le cône est dentelé et dont le manche présente en regard à son extrémité une cloche circulaire dont la surface interne s'emboíte exactement sur la surface externe du cône du corps de brosse. Le sommet de la cloche étant percé comme dans les exemples décrit ci dessus. Le blocage en position est réalisé par friction des deux cônes l'un dans l'autre.According to another exemplary embodiment, substantially on the transverse median plane of the brush body (fig 2b) is a truncated cone with a smooth surface (23) surmounted by same type of axis as that described where the cone is serrated and whose handle presents opposite at its end a circular bell whose internal surface fits exactly on the external surface of the cone of the brush body. The top of the bell being pierced as in the examples described above. Locking in position is achieved by friction of the two cones one in the other.
