Abstract
This invention relates to an apparatus providing rapid adjustment of a mirror which is pivotable about a vertical axis and retained in a housing, especially a vehicle rear view mirror, whereby the mirror is operated by an actuator having movement separated from the axis of rotation of the mirror itself and causing the mirror to rotate beyond its preset adjustment position through a preset angle, the mirror retaining contact which the actuator by means of a spring element. Movement of the actuator is controlled by a rotatable operating disk having a peripheral control curve. As the operating disk rotates, it passes through a movement arc which determines the movement of the actuator and the pivot angle of the mirror; this arc is followed by a rest phase arc which determines the final adjustment position of the actuator and the mirror; this arc is followed by a return arc which controls the return of the mirror and the actuator to their initial adjustment positions; the duration, extent and limits of the pivoting movement are all controlled by the configuration of the operating disk.
