Abstract
The vibratory-rotary motion converter may comprise a vibratory member having a generally cylindrical external surface, supporting means for supporting the vibratory member for axial vibratory motion along the cylindrical axis of such surface, vibration producing means for causing such axial vibratory motion of such member, a rotary member slidably and rotatably mounted around such cylindrical surface for rotary motion relative thereto about the cylindrical axis thereof, a shoulder member on the vibratory member and having a shoulder facing toward said rotary member, and at least one flexible resilient arm on the rotary member and having an end portion extending toward said shoulder for engagement therewith, the arm being oriented for flexing motion in a direction such that the end portion of the arm has axial and circumferential components of motion relative to the cylindrical axis, the rotary member being biased toward the shoulder to produce a yieldable biasing force between the shoulder and the end portion of the arm so that axial vibration of the vibratory member produces flexure of the arm and consequent rotation of the rotary member. One display device comprises a rotary hub frictionally driven by such rotary member and rotatably mounted around the cylindrical surface of the vibratory member, at least one mobile display element positioned outwardly from the rotary hub, and a flexible resilient spoke-like connecting element extending between the rotary hub and the mobile display element for causing such element to rotate with the rotary hub while affording flexibility therebetween.
