Dental flossing device
First Claim
1. A dental flossing device, comprising:
- a housing manually grippable by a user;
a pair of spaced arms projecting from one end of the housing and including floss-engaging means for engaging the opposite ends of a length of dental floss to be tautly secured along a dental floss axis between said arms;
and a drive within said housing for displacing the length of dental floss when secured between said arms;
characterized in that said drive displaces at least one end of the length of dental floss, when secured between the arms, through a unidirectional, curved, closed-loop planar path defined by the two axes substantially perpendicular to each other and to said dental floss axis.

Abstract
A dental flossing device includes a housing manually grippable by a user, a pair of spaced arms projecting from one end of the housing for engaging the opposite ends of a length of dental floss to be tautly secured along a dental floss axis between the arms, and a drive for displacing the length of dental floss when secured between the arms. The drive displaces at least one end of the length of dental floss, when secured between the arms, through a unidirectional, curved closed-loop planar path defined by the two axes substantially perpendicular to each other and to the dental floss axis. In one described embodiment, only one end of the length of dental floss is displaced in the above-defined unidirectional, curved, closed-loop path; and in a second described embodiment, each of the two ends of the length of dental floss is displaced in the above-defined unidirectional, curved, closed-loop path.
