ABSTRACT:
An automated dental flosser (10) comprises a pair of pivotally supported tines (18) which support a movable floss span (17). A pair of rotatably supported subcapstans (38, 40) are floss-connected to each end of the floss span, respectively, and are alternately driven to reciprocate the span longitudinally. A floss dispensing spool (50) and a floss take-up spool (56), floss-connected to respective subcapstans, dispense and take up floss. A floss-engaging portion of each subcapstan differs from the other in diameter to result in a net transfer of the floss from one spool to the other. Means for reciprocating the tines moves the span up and down. A pair of stationary shield tines (16) shield the user's teeth from the reciprocating tines. A second embodiment (90) includes an astable pulse generator (106) that generates a train of pulses of alternately reversing electric charge. Pulses of one charge are of longer duration than those of the other charge. A reversible DC motor (104) is drivingly connected to floss dispensing and take-up spools (98, 100) which are floss-connected to each end, respectively, of a tine supported floss span (96). The motor, energized by the alternating pulses, alternately reverses direction to reciprocate the floss span. A net transfer of floss from one spool to the other results from the longer pulses. A third embodiment (116) includes two ultrasonic transducers (127, 128) connected to floss-supporting tines (118). The transducers are mounted at right angles to each other for reciprocating the tines and floss span up and down and side to side.
