First Claim
1. An electric toothbrush comprising:
- a body having a handle, a head, and a neck extending between said handle and said head, said body defining a hollow interior region within said body;
at least one bristle holder disposed along said head;
a motor, power source, and drive mechanism adapted to move said at least one bristle holder upon actuation, said motor, said power source, and said drive mechanism disposed in said hollow interior region of said body; and
an actuator assembly adapted to activate said motor and thereby move said at least one bristle holder, said actuator assembly including;
(i) a positionable member having an outer face accessible along an outer surface of said body of said toothbrush, said positionable member also having an oppositely directed base, said outer face having a raised region that extends outwardly from said base and which defines an aperture extending through said member from said outer face to said base, (ii) a spring member disposed within said hollow interior region of said body and proximate to said positionable member, said spring member having a first end engaged to said body of said toothbrush and a second free end opposite from said first end, (iii) a depressible member disposed in said aperture defined in said raised region of said positionable member, said depressible member having an outer end accessible along an outer surface of said body of said toothbrush and an interior end opposite from said outer end, said interior end disposed within said hollow interior region of said body, and (iv) a cam member engaged with said spring member and movable therewith, said cam member having a cam surface directed towards said base of said positionable member and said interior end of said depressible member.

Abstract
An actuator assembly for an electric toothbrush is disclosed. The actuator assembly includes a positionable member accessible along the outer surface of the toothbrush body. The actuator assembly further includes a spring member retained within the interior of the toothbrush body which urges a cam member against the underside of the positionable member. The positionable member defines an aperture extending through its midsection within which is disposed a depressible member. The depressible member has an outer end which is also accessible along the outer surface of the toothbrush body. Upon pressing the depressible member, the cam member and spring are urged against an electrical circuit provided within the body of the toothbrush which is used to selectively operate a motor and drive mechanism to move one or more sets of bristles. The actuator assembly additionally includes a feature of providing a raised region along an outer surface of the positionable member which guards against accidental or unintentional depressing of the depressible member.

17. An actuator assembly adapted for use with and incorporation within an electric toothbrush, said actuator assembly comprising:
-
a linearly positionable member adapted for placement along an outer region of said toothbrush, said member having an outer face and an oppositely directed base face, said member defining an aperture extending through said member between said outer face and said base face, said member further having a raised region adjacent said aperture;
a depressible member moveably retained within said aperture defined in said positionable member, said depressible member having an outer end and an opposite inner end;
a spring and cam assembly disposed along said base face of said positionable member and adapted for securing within said toothbrush, said spring and cam assembly having a cam surface that contacts said inner end of said depressible member and urges said outer end of said depressible member outward from said outer face of said positionable member; and
wherein said raised region of said positionable member extends outward from said outer face a distance that is equal to or greater than the distance which said outer end of said depressible member extends from said outer face. - View Dependent Claims (18, 19, 20)
