Abstract
Description
Appareil d'hygiène dentaire destiné au nettoiement simultané des dents des deux maxillairesDental hygiene device intended for the simultaneous cleaning of the teeth of the two maxillae
La présente invention a pour objet un appareil d'hygiène dentaire, destiné au nettoiement simultané des dents des deux maxillaires .The present invention relates to a dental hygiene device, intended for the simultaneous cleaning of the teeth of the two maxillae.
De façon traditionnelle, le brossage des dents est réalisé au moyen d'une brosse à dents comportant un manche dont une extrémité est garnie de poils parallèles destinés à être imprégnés de pâte dentifrice. Le brossage est réalisé manuellement selon des mouvements dans des directions préférentielles . II existe également des brosses à dents à fonctionnement électrique, lesquelles sont essentiellement de deux types, celles comprenant une brosse identique à une brosse manuelle reliée à un mécanisme d'entraînement lui imprimant un mouvement de vibration ou de va-et-vient, et celles comprenant à l'extrémité d'un manche fixe, une ou plusieurs brosses aptes à être animées d'un mouvement de rotation.Traditionally, toothbrushing is carried out by means of a toothbrush comprising a handle, one end of which is lined with parallel bristles intended to be impregnated with toothpaste. Brushing is carried out manually according to movements in preferred directions. There are also electrically operated toothbrushes, which are essentially of two types, those comprising a brush identical to a manual brush connected to a drive mechanism imparting to it a vibration or reciprocating movement, and those comprising at the end of a fixed handle, one or more brushes capable of being driven in a rotational movement.
Que ce soit avec des brosses manuelles ou électriques, le brossage pour être efficace doit durer un minimum de temps pour chacune des dents, et par conséquent l'opération totale de brossage dure relativement longtemps, en tout cas plusieurs minutes. Cette durée semble cependant trop longue, et l'opération trop fastidieuse pour la plupart des gens, lesquels abrègent le brossage bien avant d' atteindre le seuil d'efficacité. Pour pallier cet inconvénient, il a été proposé des appareils permettant de nettoyer simultanément plusieurs dents voire toutes, comme c'est le cas avec les appareils décrits par exemple dans les documents GB 546.136, US 4.224.710 et ΞP 101.618. A cet effet, ces appareils comportent un bloc destiné à être introduit dans la bouche de l'utilisateur, et comprenant deux faces opposées dans chacune desquelles est pratiquée une gorge destinée à accueillir une arcade dentaire ou une partie de celle-ci, les gorges étant garnies intérieurement de brosses, ou éléments de brosses .Whether with manual or electric brushes, brushing to be effective must last a minimum of time for each of the teeth, and therefore the total brushing operation lasts relatively long, at least several minutes. However, this duration seems too long, and the operation too tedious for most people, who shorten brushing well before reaching the threshold of effectiveness. To overcome this drawback, devices have been proposed for simultaneously cleaning several or even all teeth, as is the case with the devices described for example in documents GB 546,136, US 4,224,710 and ΞP 101,618. To this end, these devices comprise a block intended to be introduced into the mouth of the user, and comprising two opposite faces in each of which is practiced a groove intended to accommodate a dental arch or a part thereof, the grooves being internally lined with brushes, or brush elements.
Dans le document GB 546.136, l'appareil est destiné à être animé d'un mouvement de va-et-vient comme avec une brosse à dents, de même pour l'appareil du document US 4.224.710 où les brosses sont de plus montées sur des systèmes amortisseurs. En ce qui concerne l'appareil décrit dans le document EP 0.101.618, les brosses y sont animées d'un mouvement de rotation. Les appareils de conception simple, c'est-à-dire ceux des documents GB 546.136, US 4.224.710 sont d'un usage fastidieux, tandis que celui du document ΞP 101.618 est d'une trop grande complexité pour garantir sa longévité.In document GB 546.136, the device is intended to be moved back and forth as with a toothbrush, similarly to the device of document US 4,224,710 where the brushes are further mounted on damping systems. As regards the apparatus described in document EP 0.101.618, the brushes are driven therein by a rotational movement. The devices of simple design, that is to say those of the documents GB 546.136, US 4,224,710 are tedious to use, while that of the document ΞP 101,618 is too complex to guarantee its longevity.
On connaît également par les documents US 5.337.435 US 5.177.827, DE 34 37 191 des appareils analogues à celui du document EP 0.101.618 en ce sens qu'ils comprennent dans une enveloppe destinée à être placée dans la bouche, une série de brosses aptes à être animées d'un mouvement en vue du nettoiement des dents. Outre leur complexité de construction, ces appareils sont confrontés à l'inconvénient du dépôt de pâte dentifrice, laquelle en séchant a tendance à entraver le mouvement des brosses.We also know from documents US 5,337,435 US 5,177,827, DE 34 37 191 of devices similar to that of document EP 0.101.618 in the sense that they comprise in an envelope intended to be placed in the mouth, a series brushes capable of being moved in order to clean the teeth. In addition to their construction complexity, these devices are faced with the drawback of depositing toothpaste, which when drying tends to impede the movement of the brushes.
On connaît également le document DE 201.20.955 qui décrit un appareil de brossage automatique, comprenant deux blocs munis chacun d'une gorge garnie de poils et destinée à accueillir une arcade dentaire, ainsi qu'un moyen moteur, destiné à être lui- aussi placé dans la bouche et qui est apte à faire bouger un bloc par rapport à l' autre en sorte de créer un mouvement de brossage. Un tel appareil, outre l' inconfort de son utilisation, est peu efficace du fait de la faible amplitude du mouvement de bros age.Document DE 201.20.955 is also known, which describes an automatic brushing device, comprising two blocks each provided with a groove furnished with bristles and intended to accommodate a dental arch, as well as a motor means, intended to be also placed in the mouth and which is able to move one block relative to the other so as to create a brushing movement. Such an apparatus, in addition to the discomfort of its use, is not very effective due to the small amplitude of the brushing movement.
On connaît aussi par le document WO 02/47512 un appareil de brossage automatique qui comprend d'une part deux éléments en matériau déformable présentant la forme d'une goulotte, garnis intérieurement de poils et destinés chacun à couvrir une arcade dentaire, et d'autre part un moyen moteur apte à être tenu à la main et solidarisé auxdits éléments par l'intermédiaire de trois liaisons, l'une, centrale, liée aux bords internes desdits éléments, et les deux autres, latérales, liées pour l'une aux bords externes droits desdits éléments tandis que l'autre est liée aux bords externes gauches . Le moyen moteur est apte à animer la liaison centrale et les liaisons latérales de manière opposée, et dans un mouvement alternatif, en sorte de réaliser un mouvement de cisaillement apte à déformer lesdits éléments afin de générer un mouvement de brossage. Un tel appareil est d'une grande complexité de fabricationAlso known from document WO 02/47512 is an automatic brushing device which comprises on the one hand two elements of deformable material having the shape of a chute, internally lined with bristles and each intended to cover a dental arch, and on the other hand, a motor means capable of being held at the hand and secured to said elements by means of three links, one, central, linked to the internal edges of said elements, and the other two, lateral, linked for one to the straight external edges of said elements while the other is linked to the left outer edges. The drive means is capable of animating the central connection and the lateral connections in an opposite manner, and in an alternating movement, so as to produce a shearing movement capable of deforming said elements in order to generate a brushing movement. Such a device is of great manufacturing complexity

Le vilebrequin 50 traverse verticalement l'enveloppe 20, au travers d'une rotule élastique 22 et son extrémité extérieure 51 présente latéralement un moyen 52 d'assujettissement du bloc 1, qui consiste en l'occurrence en un évidement 53 dans lequel est introduit sans jeu un embout 17 qui fait saillie du bloc 1 en avant de la partie courbe de celui-ci. Le vilebrequin 50, en association avec l'excentrique 31, transforme le mouvement de rotation du moteur 3 en un déplacement de l'axe XX' de l'embout 17, et donc du bloc 1, selon un cercle, que l'on peut assimiler à des oscillations ou à des vibrations.The crankshaft 50 passes vertically through the casing 20, through an elastic ball joint 22 and its outer end 51 has laterally a means 52 for securing the block 1, which in this case consists of a recess 53 into which is introduced without game a tip 17 which projects from block 1 in front of the curved part thereof. The crankshaft 50, in association with the eccentric 31, transforms the rotational movement of the engine 3 into a displacement of the axis XX 'of the end piece 17, and therefore of the block 1, in a circle, which can be likened to oscillations or vibrations.
De manière avantageuse, le vilebrequin est percé d'un canal 54 connecté au réservoir 4 , et apte à être abouté à un canal 18 percé dans l'embout 17 et débouchant dans les gorges 10 et 11 en plusieurs orifices 19.Advantageously, the crankshaft is pierced with a channel 54 connected to the reservoir 4, and capable of being abutting a channel 18 pierced in the end piece 17 and opening into the grooves 10 and 11 in several orifices 19.
Le réservoir 4 est par ailleurs associé à des moyens de délivrance de pâte dentifrice, qui consistent en un piston 40 apte à se déplacer axialement dans le réservoir 4, mû par un dispositif à vis sans fin 41 entraînée par une mollette filetéeThe reservoir 4 is also associated with means for delivering toothpaste, which consist of a piston 40 capable of moving axially in the reservoir 4, driven by a worm device 41 driven by a threaded wheel.
42 manœuvrable manuellement.42 manually operated.
On notera que la distribution de pâte dentifrice peut également être réalisée par l'intermédiaire d'un système à fonctionnement électrique, dans tous les cas il est prévu d'équiper le canal 18 d'un système anti-retour.It will be noted that the distribution of toothpaste can also be carried out by means of an electrically operated system, in all cases it is planned to equip the channel 18 with a non-return system.
On notera que du point de vue fabrication, le bloc 1 peut être réalisé par l'assemblage de deux pièces, une pour chacune des arcades . Ξn référence maintenant à la figure 5, on peut voir un mode de réalisation particulier du bloc 1, lequel présente deux zonesIt will be noted that from the manufacturing point of view, the block 1 can be produced by assembling two parts, one for each of the arches. Référencen now referring to FIG. 5, we can see a particular embodiment of block 1, which has two zones
E constituées d'une matière plus souple que celle employée pour le reste du bloc 1, et qui consiste par exemple en un élastomère. Ces deux zones Ξ sont, dans le mode de réalisation représenté, disposées dans la partie courbe des arcades, de préférence en regard des zones destinées à recevoir les canines, en sorte de permettre l'écartement des deux branches du U que forme le bloc 1, et donc l'adaptation de ce dernier à des anatomies différentes .E made of a more flexible material than that used for the rest of block 1, and which for example consists of an elastomer. These two zones Ξ are, in the embodiment shown, arranged in the curved part of the arches, preferably opposite the zones intended to receive the canines, so as to allow the spacing of the two branches of the U formed by the block 1 , and therefore the adaptation of the latter to different anatomies.
Selon une variante, non représentée, le bloc 1 est constitué de plusieurs sections rigides réunies deux à deux par une zone Ξ, lui donnant une forme annelée favorisantAccording to a variant, not shown, the block 1 consists of several rigid sections joined in pairs by a zone Ξ, giving it a ringed shape favoring
1' adaptation. En référence maintenant aux figures 6a et 6b, on peut voir que, de manière simplifiée et schématique, le bloc 1 est constitué de l'assemblage de différents composants, principalement de parois agencées pour former les gorges 10 et 11 , et qui sont attachées les unes aux autres par 1' intermédiaires de zones P, faites, comme les zones Ξ d'une matière souple telle qu'un élastomère.1 adaptation. With reference now to FIGS. 6a and 6b, it can be seen that, in a simplified and schematic manner, the block 1 is consisting of the assembly of different components, mainly walls arranged to form the grooves 10 and 11, and which are attached to each other by 1 'intermediaries of zones P, made, like the zones Ξ of a flexible material such that 'an elastomer.
Cette construction autorise un certain evasement des gorges 10 et 11, et favorise, de manière accrue lorsqu'elle est associée à des zones Ξ, l'adaptation du bloc 1 à l'anatomie de 1'utilisateur. This construction allows a certain flaring of the grooves 10 and 11, and promotes, in an increased manner when associated with zones Ξ, the adaptation of the block 1 to the anatomy of the user.
