Abstract

An improved dental flossing tool having reciprocating tines supporting the flossing material and biased apart to assure proper tension on the flossing material, while having means carried by the tines for moving the flossing material between the tines and having removable head means to permit replacement of the head to provide sterile use for subsequent users.

Claims

1. A dental flossing tool comprising:

a hollow, generally cylindrical handle,

a bifurcated head portion mounted on one end of said handle and having a pair of arms extending upwardly from said handle,

means carried by the arms of said head portion and movable within said arms for supporting a quantity of dental flossing material,

a motor located within said handle, and

drive means coupling said motor to move the flossing material supporting means to provide movement to said flossing material in a direction substantially parallel to the longitudinal axis of said tools.

2. The dental flossing tool of claim 1 wherein:

the arms of said head portion extend at an angle of approximately 60°

to the axis of said handle.

3. The dental flossing tool of claim 1 wherein:

said drive means includes a pair of tines each moveable within a respective one of said arms and each carrying said floss supporting means, and

a crank driven by said motor for causing reciprocal movement of said tines to move said floss supporting means.

4. The dental flossing tool of claim 3 wherein:

said crank serves to cause alternate reciprocating movement of said tines.

5. The dental flossing tool of claim 3 wherein:

said crank serves to cause simultaneous reciprocating movement of said tines.

6. The dental flossing tool of claim 3 wherein:

said floss supporting means are wheels and said crank serves to cause reciprocal movement of said tines and also to cause rotation of said wheels.

7. The dental flossing tool of claim 1 wherein:

said floss supporting means are wheels.

8. The dental flossing tool of claim 7 wherein:

said wheels are driven by said drive means.

9. The dental flossing tool of claim 1 wherein:

said head portion is removably mounted on said handle.

10. The dental flossing tool of claim 1 further comprising:

resilient means normally urging said arms apart to assure proper tension on said flossing material.

11. The dental flossing tool of claim 1 wherein:

said drive means includes a clutch member, and

means driveable by said clutch for moving said floss supporting means.

12. The dental flossing tool of claim 1 wherein:

said head portion is removably mounted on said handle and said means driveable by said clutch is located within said head portion, while said clutch is located within said handle.
