ABSTRACT:
A hand powered rotatable toothbrush is characterized by elements, such as tufts of brush bristles, positionally fixed to the brush head to frictionally engage tooth surfaces and thereby positionally stabilize the brush head so that a distal portion of the brush handle can be longitudinally reciprocated relative to the brush head. One or more rotatable brush members mounted on the brush head are operatively connected to the distal handle portion, as by a rack and pinion, to cause the brush members to be rotated in response to longitudinal handle reciprocation. In one embodiment the rotatable brush member cyclically rotates in opposite directions in response to back and forth linear motion of the handle. In another embodiment the rotation of the brush member is in the same direction, irrespective of the direction in which the handle moves.
