Title
(EN) ELECTRIC TOOTHBRUSH HAVING DUAL HEADS WITH OSCILLATORY MOVEMENT
(FR) BROSSE A DENT ELECTRIQUE A DOUBLE TETE AVEC MOUVEMENT OSCILLANT
Abstract
(EN)
A brush head portion for an electric toothbrush is adapted to be removably connected to a power handle. The brush head portion comprises a pair of opposed bristle head portions. A longitudinal hollow shaft and terminates at a fixed cover portion which is shaped and dimensioned so as to overlie the pair of opposed bristle head portions, which are mounted on a stem. A longitudinal drive shaft extends through the hollow shaft, and transmits rotational driving force to a crank formed at the outer end of the drive shaft. A drive means is located between each of the bristle head portions and the underside of a respective region of the fixed cover portion , and is mounted on the crank so as to have reciprocating motion imparted thereto as the crank is driven. A wedge is formed on the underside of the fixed cover portion in the region overlying each respective bristle head portion, or on the top surface of each respective block. When a reciprocating motion is imparted to the drive means by the crank, the drive means is moved from side-to-side so as to slide from the top towards the bottom of one of the wedges and from the bottom towards the top of the other of the wedges, so as to impart an oscillatory movement to the pair of opposed bristle head portions.
(FR)
L'invention porte sur une tête de brosse à dent électrique qui est adaptée pour être raccordée amovible à une prise de force. La partie tête comporte une paire de têtes opposées pourvues de poils. Un arbre creux longitudinal se termine au niveau d'un couvercle fixe qui est conçu et dimensionné de façon à recouvrir la paire de têtes opposées qui sont montés sur une tige. Un arbre de commande longitudinal s'étend dans l'arbre creux et transmet une force d'entraînement rotative à une manivelle formée à l'extrémité extérieure de l'arbre de commande. Un dispositif de commande est placé entre chacune des têtes et sous une région respective du couvercle fixe, et est monté sur la manivelle de sorte que lui soit communiquer un mouvement de va et vient lors de l'entraînement de la manivelle. Un coin est formé sur le dessous du couvercle fixe dans la région recouvrant chaque tête, ou sur la surface supérieure de chaque bloc respectif. Lorsqu'un mouvement de va et vient est communiqué au dispositif de commande par la manivelle, le dispositif de commande se déplace d'un côté à l'autre de façon à coulisser du haut vers le bas d'un des coins et du bas vers le haut de l'autre coin et à communiquer ainsi un mouvement oscillant à la paire de têtes opposées.
