Abstract
A powered toothbrush is provided with a pair of disc-like rotary brushes mounted for rotation about a axis generally perpendicular to the length of the brush. The rotary brushes are in axially spaced relationship and are provided with inwardly directed bristles. Between the rotary brushes, upper and lower linear brushes are mounted above and below the axis of rotation for linear reciprocating motion generally perpendicular to that axis. The upper brush has upwardly directed bristles, and the linear brushes are mounted to the rotary brushes so as to be brought into reciprocal, linear movement when the rotary brushes are reciprocated angularly.
Claims13
A toothbrush comprising;
- a elongated main body;
- a generally disc-shaped rotary brush having generally axially directed peripheral bristles;
- axle means mounting said rotary brush to said main body for rotational movement about an axis which is transverse to the length of said body;
- means at least partially disposed in said main body for providing reciprocating, rotary motion to said rotary brush;
- a linear brush having bristles directed away from said axis;
- and
- means for mounting said linear brush to said rotary brush so that said linear brush reciprocates linearly along the length of said body as said rotary brush reciprocates rotationally.
