ABSTRACT:
This application includes a number of embodiments of a spring powered toothbrush for cleaning teeth. A wind-up spring is located in the base of the toothbrush which spring provides power for a gear train including a drive shaft assembly that is designed to bring about rapid movement of the brush portion of the toothbrush to aid in cleaning the teeth. The drive mechanism is controlled by a spring biased push button in the toothbrush housing. In one version the brush portion of the toothbrush includes a rotatable brush section that is gear driven by the drive shaft. In another version the upper portion of the toothbrush is vibrated by an offset weight connected to the drive shaft and in a third version the drive shaft includes an offset weight that acts to oscillate a movable brush section by intermittent engagement between the; weight and brush section.
