Description
Dispositif d'emboîtement d'une tige de brosse à dents sur un axe
Le brevet principal a pour objet un dispositif d'emboîtement axial de la tige d'une brosse à dents automatique sur l'axe de son mécanisme d'entraine- ment dans lequel l'une de ces deux pièces présente un dard s'engageant dans une creusure axiale correspondante de l'autre pièce, l'une de ces deux pièces présentant, en outre, au moins un tenon transversal s'engageant à crans dans un logement pratiqué le long d'une fente longitudinale de l'autre pièce. Dans une forme d'exécution particulière le dard est solidaire dudit axe d'entrnînement; dans une autre forme d'exécution particulière, le dard porte un seul tenon.
La présente invention a pour objet un tel dispositif, présentant tous ces caractères et caractérisé en outre par le fait que la fente s'ouvre dans la paroi de la tige, du côté où sont implantés les poils de la brosse.
Le dessin annexé représente, à titre d'exemple, une forme d'exécution de l'objet de l'invention.
La fig. 1 en est une vue en plan et la fig. 2 une vue en élévation.
Au dessin, comme dans celui du brevet principal, 1 représente la tige de la brosse à dents dans la partie supérieure de laquelle sont implantés les poils 2 et dont l'extrémité inférieure présente un dispositif d'emboltement sur l'axe 3 du mécanisme d'entramv ment de la brosse. Cet axe 3 présente un dard 4, de section droite rectangulaire, s'engageant amoviblement dans une creusure correspondante 5 de la tige.
Le dard porte en outre un tenon transversal 6 qui, lors de l'emboîtement de la tige, pénètre dans la fente 7 pour s'engager dans des logements 8.
La fente est pratiquée du côté où sont 2 implan- tés les poils, dans le but de réduire l'écartement des lèvres de la fente 7 au minimum lorsque l'ensemble de la brosse est soumis à une tension due à son action dans la bouche. Cet écartement est en effet plus faible que si la fente était disposée du côté opposé puisque l'action principale du dard sur les parois de la tige se donne approximativement dans le sens des flèches a et surtout A.
REVENDICATION
Dispositif selon la revendication du brevet prin- cipal et les sous revendications 1 et 2, caractérisé par le fait que la fente s'ouvre dans la paroi de la tige, du côté où sont implantés les poils de la brosse.

Device for interlocking a toothbrush rod on an axis
The main patent relates to a device for axially interlocking the rod of an automatic toothbrush on the axis of its drive mechanism in which one of these two parts has a stinger engaging in a corresponding axial recess of the other part, one of these two parts having, in addition, at least one transverse tenon engaging in detents in a housing formed along a longitudinal slot of the other part. In a particular embodiment, the stinger is integral with said drive axis; in another particular embodiment, the stinger carries a single tenon.
The object of the present invention is such a device, having all these characteristics and further characterized in that the slot opens in the wall of the rod, on the side where the bristles of the brush are located.
The appended drawing represents, by way of example, an embodiment of the object of the invention.
Fig. 1 is a plan view thereof and FIG. 2 an elevation view.
In the drawing, as in that of the main patent, 1 represents the rod of the toothbrush in the upper part of which the bristles 2 are implanted and the lower end of which has a hinging device on the axis 3 of the mechanism d brush start-up. This axis 3 has a stinger 4, of rectangular cross section, removably engaging in a corresponding recess 5 of the rod.
The stinger also carries a transverse tenon 6 which, during the fitting of the rod, penetrates into the slot 7 to engage in the housings 8.
The slit is made on the side where the bristles are 2 implanted, in order to reduce the distance between the lips of the slit 7 to a minimum when the whole of the brush is subjected to a tension due to its action in the mouth. . This spacing is in fact smaller than if the slot were placed on the opposite side since the main action of the stinger on the walls of the rod is given approximately in the direction of the arrows a and especially A.
CLAIM
Device according to the claim of the main patent and the sub-claims 1 and 2, characterized in that the slot opens in the wall of the rod, on the side where the bristles of the brush are implanted.
** ATTENTION ** end of DESC field can contain start of CLMS **.
