Abstract
Description
L'invention concerne une brosse à dents à usage domestique. The invention relates to a toothbrush for household use.
Selon les médecins l'emploi de brosses à dents ordinaires ne permet pas un brossage régulier et complet de toutes les dents0 On constate que Si la surface des dents de devant (incisives, canines, quelques molaires) est cor~ecte- ment nettoyée, les autres surfaces (intérieures et dessus des dents) le sont d'une manière peu satisfaisante et certaines zones ne sont que très peu, voire jamais atteintes par la brosse, comme par exemple les dents de sagesse. Outre l'aspect esthétique, il en resulte des inconvénients comme l'apparition d'une mauvaise haleine, la formation de réservoirs d'alimentsentre certaines dents et l'apparition de caries
L'invention a pour but de combler ces lacunes en réalisant une brosse à dents de forme plus rationnelle, de plus grande efficacité et ayant la souplesse d'emploi dtune brosse ordinaire.According to the doctors, the use of ordinary toothbrushes does not allow regular and complete brushing of all the teeth. other surfaces (inside and above the teeth) are unsatisfactory and certain areas are only very little, if ever reached by the brush, such as wisdom teeth. In addition to the aesthetic aspect, this results in drawbacks such as the appearance of bad breath, the formation of food reservoirs between certain teeth and the appearance of cavities.
The object of the invention is to fill these gaps by making a toothbrush with a more rational shape, with greater efficiency and having the flexibility of use with an ordinary brush.
La bresse à dents selon l'invention se compose d'un mn- che unique et d'une tette interchangeable en forme de gouttière. The toothbrush according to the invention consists of a single handle and an interchangeable teat in the shape of a gutter.
Suivant une caractéristique, la surface intérieure de la gouttière comporte des rangées de poils parallèles à l'axe du manche et des rangées dis-osées en arc de cercle dans des plans parallèles entre eux et orthogonaux à l'axe du manche. According to one characteristic, the interior surface of the gutter comprises rows of bristles parallel to the axis of the handle and rows dis-dared in an arc of a circle in planes parallel to each other and orthogonal to the axis of the handle.
Suivant une autre caractéristique, la fixation des poils à l'intérieur de la gouttière est obtenue par surmoulage. According to another characteristic, the fixing of the bristles inside the gutter is obtained by overmolding.
Suivant une autre caractéristique, la liaison du manche et de la gouttière est fixe (par exemple collage ou soudage). According to another characteristic, the connection of the handle and the gutter is fixed (for example gluing or welding).
Suivant une autre caractéristique, la gouttière est fiw xée d'une manière rigide mais amovible sur le manche (par exemple: liaison par tenon et mortaise, par clipsage). According to another characteristic, the gutter is fi xed in a rigid but removable manner on the handle (for example: connection by tenon and mortise, by clipping).
Suivant une autre caractéristique, la gouttière est articulée sur le manche avec point dur pour la position d'emploi la plus fréquente. According to another characteristic, the gutter is articulated on the handle with a hard point for the most frequent position of use.
Le dessin annexé, donné à titre d'exemple non limitatif, permettra de mieux comprendre les caractéristiques de l'invention. The appended drawing, given by way of nonlimiting example, will allow a better understanding of the characteristics of the invention.

La brosse à dents 3 comprend un manche 2 et une tette 1 en forme de gouttière sur la facé interne de laquelle dépassent des soies ou poils 4 (fig. i). The toothbrush 3 comprises a handle 2 and a tette 1 in the form of a gutter on the internal facet of which project bristles or bristles 4 (fig. I).
Suivant une première variante de la brosse 3, le manche 2 et la tête 1 sont réalisés en une seule pièce (fig. 4). According to a first variant of the brush 3, the handle 2 and the head 1 are produced in one piece (fig. 4).
Suivant une deuxième variante de la brosse 3, le manche 2 comporte une mortaise 5 dans laquelle vient coulisser un tenon 6 prévu sur la tete 1 (fig. 5)
Suivant une troisième variante de la brosse 3, l'articulation du manche 2 et de la tette 1 s'effectue par un axe 7 rapporté ou moulé avec l'une des deux pièces (fig. 6).According to a second variant of the brush 3, the handle 2 includes a mortise 5 in which slides a stud 6 provided on the head 1 (fig. 5)
According to a third variant of the brush 3, the articulation of the handle 2 and the tette 1 is effected by an axis 7 attached or molded with one of the two parts (fig. 6).
Le fonctionnement est le suivant
- le mode de brossage est le meme que celui nécessaire avec les brosses à dents ordinaires,
- la gouttière recouvrant toute la surface des dents, seul uii mouvement de translation horizontale suffit;
- avec la variante non articulée il est nécessaire de sortir la brosse de la bouche, de la retourner et de la rentrer de nouveau, pour passer d'un coté à l'autre de la mâchoire. The operation is as follows
- the brushing mode is the same as that required with ordinary toothbrushes,
- the gutter covering the entire surface of the teeth, only a horizontal movement of translation is sufficient;
- with the non-articulated variant it is necessary to take the brush out of the mouth, turn it over and back in again, to pass from one side to the other of the jaw.
Les avantages de l'iuveution sont les suivants
- la forme de 1 gouttière permet le brossage de toute la surface de la dent et de la liaison dent-gencive
- la variante articulée de l'invention permet deatbeindre plus facilement les dents du lond (type dents de sagesse); elle permet de ne pas avoir à sortir la brosse de la bouche dans le cas indiqué précédemment; indépendamment de la position du manche, la gouttière suit parfaitement le contour des dents à nettoyer; la présence possible d'un point dur permet de prilrilesier la position manche-gouttière qui est la plus employée lors du brossage.The advantages of iuveution are as follows
- the shape of 1 gutter allows brushing of the entire surface of the tooth and the tooth-gum connection
- the articulated variant of the invention makes it easier to reach london teeth (wisdom teeth type); it eliminates the need to remove the brush from the mouth in the case indicated above; regardless of the position of the handle, the gutter perfectly follows the contour of the teeth to be cleaned; the possible presence of a hard point allows to prilrile the handle-gutter position which is most used during brushing.
Dans la variante des figures 9 et 10, la gouttière 1 comporte deux parois latérales 8 qui sont reliées entre elles par un axe d'articulation- 9, disposé longitudinalement par rapport au manche 2. il va de soi que cet axe 9 peut être réalisé de diverses façons. En particulier
- on peut réaliser séparément les deux parois latérales 8, que relie une charnière dans laquelle est engagé un axe 9, tandis qu'un ressort ou caoutchouc, non représenté, tend à rappeler les deux parois 8 l'une vers l'antre (flache 10, figure 9)
- on peut réaliser d'une pièce les deux parois 8 en mati re plastique injectée, l'axe 9 étant matérialise par une zone de moindre épaisseur ou "charnière voile" prévue dans la matière plastique, dont l'élasticité propre constitue le moyen de rappel
Dans un cas comme dans l'autre, la gouttière 1 occupe au repos la position d la figure 9, c'est-à-dire que les deux parois 8 sont proches l'une de l'autre, ce qui permet de brosser efficacement des dents 11 peu larges (par exemple les incisives). ,çu contraire, lorsqu'on brosse une dent large (par exemple une molaire 12, figure 10), les deux parois 8 stécarteht élastiquement. On voit que dans tous les cas cela assure un brossage efficace. In the variant of Figures 9 and 10, the gutter 1 has two side walls 8 which are connected together by a hinge pin 9, arranged longitudinally relative to the handle 2. it goes without saying that this axis 9 can be produced in various ways. In particular
- the two side walls 8 can be produced separately, which is connected by a hinge in which an axis 9 is engaged, while a spring or rubber, not shown, tends to bring the two walls 8 back towards one another (flache 10, figure 9)
- The two walls 8 can be produced in one piece from injected plastic, the axis 9 being materialized by a zone of lesser thickness or "veil hinge" provided in the plastic, whose own elasticity constitutes the means of reminder
In one case as in the other, the gutter 1 occupies at rest the position of FIG. 9, that is to say that the two walls 8 are close to each other, which makes it possible to brush effectively. teeth 11 not very wide (for example the incisors). , seen otherwise, when brushing a wide tooth (for example a molar 12, Figure 10), the two walls 8 stecarteht elastically. We see that in all cases this ensures effective brushing.
