Abstract

An electrically powered mechanically driven toothbrush comprising an elongated preferably cylindrical thin casing formed in two parts, one for batteries, the other for the motor. The toothbrush shank is secured to the motor section while a switch physically separates the batteries from the motor and selectively connects the motor to the batteries for operation.

Claims

1. A mechanically driven toothbrush comprising an elongated tubular relatively thin casing having a maximum outside diameter of 28 mm, said casing being formed in two sections having the same diameter and detachably secured to each other, a motor in one of said sections, the other of said sections being substantially twice the length of said one section, means for causing vibrations drivingly connected to said motor disposed in said one section, a toothbrush shank detachably secured to said one section, batteries in said other section, and switch means mounted in said one section and having contact means extending into said other section for selectively electrically operatively connecting said motor to said batteries, said switch means being disposed and extending between said motor and said batteries, said switch means extending transversely of said casing and being mounted on the sides of the casing and being selectively actuable from both sides of said casing, said contact means including a pair of contact springs connected respectively to said motor and said batteries, said switch means including a displaceable pin, said pin having an insulating jacket thereon and an annular groove therein, said casing having elastic covers on opposed sides thereof, said pin being engageable by said covers and being movable diametrically of said casing to selectively engage said contact springs in said groove and with said insulative jacket to respectively complete and break an operative electric circuit from said batteries to said motor.
