Embodiment Construction

[0022] Before describing the various preferred embodiments, it is instructive to define the various types of motions that the movable bristles of the various toothbrushes may undergo. As used herein, the term “angular motion” refers to any angular displacement. “Linear motion” is movement along a straight or substantially straight, line or direction. “Curvilinear motion” is movement that is neither completely linear nor completely angular but is a combination of the two (e.g., curvilinear). These motions can be constant or periodic. Constant motion refers to motion that does not change direction or path (i.e., is unidirectional). Periodic motion refers to motion that reverses direction or path. Constant angular motion is referred to as rotary motion, although features herein may be described as “rotatably mounted” which is intended to merely mean that angular motion, whether periodic or constant, is possible. Periodic angular motion is referred to as oscillating motion. Curvilinear ...

Abstract

An electric toothbrush is provided. The electric toothbrush has an elongated body, a head, and a neck extending between the body and the head. A plurality of bristle carriers each having a plurality of bristle tufts are disposed on the head. An electric motor is operatively connected to a shaft, wherein operation of the electric motor moves the shaft in a reciprocating motion and wherein the shaft is operatively connected to at least one of the bristle carriers to move the bristle carriers.

Description

CROSS REFERENCE TO RELATED APPLICATION [0001] This application claims the benefit of U.S. Provisional Application No. 60 / 464,787, filed Apr. 23, 2003, the substance of which is incorporated herein by reference.FIELD OF THE INVENTION [0002] The present invention relates to the field of toothbrushes, and more particularly, the invention relates to the field of electrically powered toothbrushes. BACKGROUND OF THE INVENTION [0003] Most known electric toothbrushes utilize a single bristle carrier that is powered or otherwise driven by an electric motor incorporated in the toothbrush. The bristle carriers in these toothbrushes generally undergo rotary motion. Although satisfactory in certain respects, a need still exists for an improved powered toothbrush design. [0004] Numerous attempts have been made to improve the design, efficiency, cleaning efficacy, simplicity, and / or commercial viability of electric toothbrushes. One approach has been the provision of multiple powered bristle carri...
