Dental flosser
First Claim
1. A dental flosser comprising a flosser element drivingly connected to a drive head member, said drive head member having a means for converting a reciprocating drive from a drive shaft of an electric motor into clockwise and counterclockwise rotational motion for rotating said flosser element, said converting means comprising a bushing with a laterally extending pin, a cylindrical sleeve that surrounds said bushing, a spiral groove in an inner surface of said bushing to engage said pin such that inter-engagement causes said bushing to be rotated as it is moved forwards and backwards within said sleeve.

Abstract
A dental flosser has a bushing with a lateral pin that engages in a spiral groove in a sleeve that surrounds the bushing. The bushing is driven backwards and forwards by a shaft and this causes a flosser element base anchor to be rotated clockwise and counterclockwise, and moved backwards and forwards at the same time during use.
