Patent

CA 2221796

An electrical driven toothbrush has a rotatable shaft (12) with a remote end (20) which fits into a slot (22) in a bristle holder (13). The holder (13) is mounted for rotation on a post (18) supported by a head (11). When the shaft (12) rotates, the remote end (20) describes a circle and drivingly engages the slot (22) to cause the holder (13) to vibrate.

On décrit une brosse à dents électrique présentant un arbre rotatif (24) dont l'extrémité supérieure s'emboîte dans une fente (22) ménagée dans le support de poils de brosserie (13). Ledit support (13) est monté de façon à pouvoir tourner sur un montant (18) soutenu par une tête (11). Lorsque l'arbre (12) tourne, l'extrémité distale (20) décrit un cercle et s'emboîte dans la fente (22) avec un mouvement d'entraînement qui fait vibrer le support de poils de brosserie (13).
