Abstract
A method and apparatus permitting arbitrary, relative motions of a distal end of a toothbrush or flosser with respect to a handle with real-time selectable motions. The toothbrush has a handle and a post, with a mechanism mechanically coupling the handle to the post permitting relative translational movement of the post with respect to the handle.
Claims21
A toothbrush comprising
- a motor operatively coupled to a first barrel cam,
- a second barrel cam and a third barrel cam operatively connected to the first barrel cam by a transmission rod,
- a first linear slide rod operatively coupled to the first barrel cam, a second linear slide rod operatively coupled to the second barrel cam, and a third linear slide rod operatively coupled to the third barrel cam, and
- a distal end assembly, where the distal end assembly is operatively coupled to the first linear slide rod, second linear slide rod, and third linear slide rod.

A toothbrush comprising
- a motor operatively coupled to a first barrel cam,
- a second barrel cam and a third barrel cam operatively connected to the first barrel cam by a transmission rod,
- a first linear slide rod have a drive slot operatively coupled to the first barrel cam, a second linear slide rod having a drive slot operatively coupled to the second barrel cam, and a third linear slide rod having a drive slot operatively coupled to the third barrel cam,
- a distal end assembly, where the distal end assembly is operatively coupled to the first linear slide rod, second linear slide rod, and third linear slide rod, and
- a mode selection switch operatively coupled to the transmissions rod that varies the rotational phase relationship between the first barrel cam and the second barrel cam as well as varies the rotational phase relationship between the first barrel cam and the third barrel cam.
