Toothbrush drive unit

An interdental brush has a handle with a helix style shape, as well as sections of long and short bristles to maximize plaque removal. The handle has a first end, a second end and a length between the first and second ends. The handle defines a longitudinal axis extending through the handle along the length. A brush extends from the handle and includes a stem projecting along the longitudinal axis and a set of bristles extending laterally outwardly from the stem. Each of the bristles has a bristle length from the stem to a bristle tip, the bristle tips collectively defining a bristle profile. In one embodiment, the bristle profile alternates along the stem between valley sections of short bristle length and mountain sections of long bristle length. The handle includes a grip portion along the length, and the grip portion is shaped such that it is twisted about the longitudinal axis in the manner of a helix.

A support arrangement having an activation mechanism to control the movement of wheels is provided. The support arrangement includes a platform, a chassis attached to the platform, a pair of wheel assemblies movably coupled to the chassis, and the activation mechanism. The pair of wheel assemblies are operable between a first state and a second state. The activation mechanism includes a track having a first stable position and a second stable position spaced along a length of the track, and a pin configured to travel along the track. Wheels are in the first state when the pin is in the first stable position and are in the second state when the pin is in the second stable position.

A braking mechanism operably engaging at least one wheel where the mechanism is capable of transitioning the at least one wheel between unlocked and locked states is provided. The braking mechanism includes a flipper and a cam. The flipper is adapted to move in X, Y and Z-directions and includes a discontinuous track having an open slot portion and a surface path portion. The open slot portion includes a home position and an engaged position. The cam includes a pin which cooperatively moves along the discontinuous track. When the at least one wheel is in an unlocked state, the pin is in the home position and when the at least one wheel is in a locked state, the pin is in the engaged position.
