ABSTRACT:
A device for applying dental floss between the teeth including a frame having a handle and a trigger. A motor and drive shaft is mounted in the frame, including motor control means operably connected to the trigger and power source means for supplying power to the motor. A drive wheel and a plurality of guide pulleys are positioned in the frame to define a path for a closed loop of dental floss under suitable tension. The path includes an open span sized to permit passage of the dental floss between a person's teeth. The drive wheel is positioned to engage the drive shaft to cause rotation of the wheel by the motor.
In a preferred embodiment, the frame includes a first portion mounting the motor to permit the drive shaft to extend outward from the first portion of the frame and a second portion mounting the guide pulleys and the drive wheel to position the dental floss loop. The second portion has a drive shaft receiving opening positioned to permit the drive shaft to engage the drive wheel upon insertion of the shaft into the opening. Mounting means removably mounting the first and second portions to one another in a drive shaft engaging position is provided. In a preferred embodiment, the mounting means includes a pair of bayonet rods mounted on the first portion of the frame extending outward in triangular relationship with the drive shaft and the second portion of the frame defines a pair of bayonet accepting means which hold the two parts of the frame together during operation.
