Description

L'invention a pour objet une brosse à dents électrique comportant une partie portant les poils dont l'axe de rotation de la brosse est situé dans un plan perpendiculaire au manche. The subject of the invention is an electric toothbrush comprising a part carrying the bristles whose axis of rotation of the brush is situated in a plane perpendicular to the handle.

I1 existe de nombreuse brosses rotatives électriques. Ces brosses ont un moteur électrique, en général dans le manche, et la partie portant les poils tourne ou vibre dans le même sens ou dans un plan sensiblement parallèle à l'axe longitudinal du manche
Du fait de cette configuration, il est impossible de brosser verticalement, notamment la face intérieure de certaines dents.There are numerous electric rotary brushes. These brushes have an electric motor, generally in the handle, and the part carrying the bristles rotates or vibrates in the same direction or in a plane substantially parallel to the longitudinal axis of the handle.
Due to this configuration, it is impossible to brush vertically, in particular the inner face of certain teeth.

L'invention tend à résoudre ce problème. The invention tends to solve this problem.

A cet effet, la brosse à dents selon l'invention comporte une partie portant les poils dont l'axe de rotation de la brosse est situé dans un plan perpendiculaire à l'axe longitudinal du manche, et ce grâce à un moyen agissant comme un retour d'angle. To this end, the toothbrush according to the invention comprises a part carrying the bristles whose axis of rotation of the brush is situated in a plane perpendicular to the longitudinal axis of the handle, and this by means of a means acting as a angle return.

La forme générale de la brosse à dents est donc un T ou un L. The general shape of the toothbrush is therefore a T or an L.

La partie de la brosse qui porte les poils est rotative. Elle a une forme cylindrique, cylindrocônique, en spirale etc... The part of the brush which carries the bristles is rotatable. It has a cylindrical, cylindroconical, spiral shape, etc.

L'axe de la partie portant les poils est fixé à l'embout du manche soit par une de ses extrémités, soit en son milieu. La forme générale de la brosse est en forme de L, lorsque l'embout du manche est fixé à l'une des extrémités de la partie portant les poils. La forme générale de ladite brosse est en forme de T lorsque l'embout du manche est fixé au milieu de l'axe de la partie portant les poils. The axis of the part carrying the bristles is fixed to the end of the handle either by one of its ends, or in the middle. The general shape of the brush is L-shaped, when the end of the handle is fixed to one of the ends of the part carrying the bristles. The general shape of said brush is T-shaped when the tip of the handle is fixed to the middle of the axis of the part carrying the bristles.

Le manche de la brosse peut comporter un embout qui, par des moyens d'accrochage, permet de fixer et d'adapter la tête de la brosse. Ladite tête de la brosse comprend le moyen qui fait office de raccord avec l'embout et la partie portant les poils. The handle of the brush may include a tip which, by means of attachment, makes it possible to fix and adapt the head of the brush. Said brush head comprises the means which acts as a connection with the nozzle and the part carrying the bristles.

Les moyens d'accrochage entre l'embout du manche et le raccord de la tête peuvent être assurés par des "clips".  The attachment means between the end of the handle and the head connector can be provided by "clips".

Le moteur électrique, qui assure la rotation, peut être disposé dans le manche, la transmission de la rotation de l'axe moteur peut être transmise par câble. The electric motor, which ensures the rotation, can be placed in the handle, the transmission of the rotation of the motor axis can be transmitted by cable.

Au niveau du raccord et de la partie portant les poils, un moyen agissant comme un renvoi d'angle permet de changer de 900 l'angle de l'axe de rotation. At the connection and the part carrying the bristles, a means acting as an angle gear allows the angle of the axis of rotation to be changed by 900.

La partie portant les poils tourne entrainé par un pignon qui engrène sur une vis sans fin reliée aux câbles de transmission. La partie cylindrique portant les poils peut être partiellement recouverte par un capot de protection.  The part carrying the bristles rotates driven by a pinion which meshes on an endless screw connected to the transmission cables. The cylindrical part carrying the bristles can be partially covered by a protective cover.

La partie portant les poils peut, bien entendu, avoir un volume autre que cylindrique, par exemple un volume ellipsoïde de révolution, une spirale, cylindrocônique... De même, la nature et les caractéristiques des poils peuvent varier pour obtenir des effets spécifiques. The part carrying the bristles can, of course, have a volume other than cylindrical, for example an ellipsoid volume of revolution, a spiral, cylindroconical ... Likewise, the nature and the characteristics of the bristles can vary to obtain specific effects.

La partie portant les poils peut être reliée au raccord de manière rigide ou articulée de manière à permettre à l'axe de rotation de s'orienter de lui-même perpendiculairement au plan des dents. The part carrying the bristles can be rigidly or articulated to the fitting so as to allow the axis of rotation to orient itself perpendicular to the plane of the teeth.

L'articulation entre le raccord et la partie portant les poils peut être une rotule. Ladite rotule peut comporter des moyens de blocage et/ou de freinage qui permettent de régler la force avec laquelle il est possible de faire tourner la partie portant les poils. Des butées peuvent également empêcher la rotation au delà d'un certain angle formé entre l'axe de rotation de la partie portant les poils et l'axe du manche. Cet angle peut par exemple, être de 600. The articulation between the fitting and the part carrying the bristles can be a ball joint. Said ball joint may include locking and / or braking means which make it possible to adjust the force with which it is possible to rotate the part carrying the bristles. Stops can also prevent rotation beyond a certain angle formed between the axis of rotation of the part carrying the bristles and the axis of the handle. This angle can for example be 600.

La figure 10 est une vue schématique de la brosse vue en coupe. Figure 10 is a schematic view of the brush seen in section.

Les figures 11 et 12 sont des vues mettant en évidence le fonctionnement de la brosse sur le maxillaire supérieur par un brossage de la face extérieure et de la face intérieure des dents. Figures 11 and 12 are views showing the operation of the brush on the upper jaw by brushing the outer face and the inner face of the teeth.

La brosse à dents est composée d'un manche 1 etd'une tête 2. The toothbrush consists of a handle 1 and a head 2.

La tête 2 de la brosse à dents est composée d'une partie portant les poils 3 et d'un raccord 4. Ledit raccord 4 vient s'accrocher au manche 1 qui comporte un embout 5 de raccordement. The head 2 of the toothbrush is composed of a part carrying the bristles 3 and of a fitting 4. Said fitting 4 is hooked onto the handle 1 which has a connecting piece 5.

Un bouton marche-arrêt 6 commande le moteur 7 qui est alimenté par des piles rechargeables 8. Un bouton inverseur 9 permet de changer le sens de rotation de la partie portant les poils. An on-off button 6 controls the motor 7 which is powered by rechargeable batteries 8. A reversing button 9 allows the direction of rotation of the part carrying the bristles to be changed.

La rotation de l'axe moteur est transmise par un câble 10 qui va jusqu'à l'embout 5 de raccordement. Le raccord 4 de la tête 2 vient s'emboîter dans l'embout 5 par des moyens d'accrochage tels que des "clips", non représentés sur les figures. Un autre câble 11 transmet la rotation dans le raccord 4. Au niveau du raccord 4 et de la partie portant les poils 3, un renvoi d'angle 12 permet de changer de 900 l'angle de l'axe de rotation. The rotation of the motor axis is transmitted by a cable 10 which goes to the connection end piece 5. The connector 4 of the head 2 fits into the end piece 5 by attachment means such as "clips", not shown in the figures. Another cable 11 transmits the rotation in the connector 4. At the connector 4 and the part carrying the bristles 3, an angle gear 12 allows the angle of the axis of rotation to be changed by 900.

Ledit renvoi d'angle peut être constitué d'une vis sans fin 13 reliée au câble 11 sur lequel engrène un pignon 14 qui fait tourner l'axe du cylindre portant les poils 3. Said bevel gear may consist of an endless screw 13 connected to the cable 11 on which a pinion 14 meshes which rotates the axis of the cylinder carrying the bristles 3.

Le cylindre portant les poils 3 peut être articulé avec le raccord 4 par une rotule 15. Ladite rotule 15 permet, à la partie portant les poils 3, de tourner autour de l'axe du manche 1. Des butées, non représentées sur les figures, peuvent limiter l'angle formé entre l'axe longitudinal de la partie portant les poils 3 et l'axe du manche 1 à environ 600. The cylinder carrying the bristles 3 can be articulated with the connector 4 by a ball joint 15. Said ball joint 15 allows the bristle bearing part 3 to rotate around the axis of the handle 1. Stops, not shown in the figures , may limit the angle formed between the longitudinal axis of the part carrying the bristles 3 and the axis of the handle 1 to approximately 600.

La tête 2 de la brosse à dents, composée du raccord 4 et de la partie portant les poils 3, peut être donc interchangeable. L'embout 4 du manche 1 peut donc recevoir plusieurs types de tête 2. Les figures 10 et 11 permettent de bien comprendre l'action de la partie portant les poils 3 qui brosse toujours les dents de bas en haut dans un plan perpendiculairement au plan de l'axe du manche 1. Le sens des flèches F1 et F2 montre que le brossage peut se faire dans les meilleures conditions sur la face extérieure des dents 16 aussi bien que sur la face intérieure des dents 16. The head 2 of the toothbrush, composed of the connector 4 and the part carrying the bristles 3, can therefore be interchangeable. The end piece 4 of the handle 1 can therefore receive several types of head 2. FIGS. 10 and 11 allow a good understanding of the action of the part carrying the bristles 3 which always brushes the teeth from bottom to top in a plane perpendicular to the plane of the axis of the handle 1. The direction of the arrows F1 and F2 shows that brushing can be done under the best conditions on the outside face of the teeth 16 as well as on the inside face of the teeth 16.

Un capot de protection 17 peut être disposé de manière à recouvrir partiellement la partie cylindrique portant les poils 3 ; le capot peut avoir une forme demi cylindique. A protective cover 17 can be arranged so as to partially cover the cylindrical part carrying the bristles 3; the cover may have a semi-cylindrical shape.

Selon le mode de réalisation représenté sur les figures, la brosse à dents a une forme générale de T. La partie portant les poils 3 est raccordée en son milieu à l'embout 5 du manche 1 de la brosse à dents.  According to the embodiment shown in the figures, the toothbrush has a general shape of T. The part carrying the bristles 3 is connected in its middle to the nozzle 5 of the handle 1 of the toothbrush.
