Abstract
A vibration motor comprises a first member for receiving an external vibration, a second member set to be brought into collision with the first member as a result of the receipt of the external vibration, and a converting mechanism provided at the first member and/or the second member and having an asymmetric configuration for establishing a relative movement of the second member upon collision of the first member thereto.
Claims10
A motor device, comprising:
- an annular member movable linearly in a direction normal to an axis of the annular member in response to an applied external reciprocal vibratory pressure;
- a plurality of equally pitched inwardly extending projections positioned at an inner annulus edge of the annular member, the distal end of each of the projections being bent obliquely to the radii of the annular member;
- a rotatable shaft member having an axis and mounted coaxially within the annulus of the annular member;
- and
- a plurality of equally pitched outward projections extending in radial alignment with a radial line of the rotatable shaft member, the outward projections being spaced from the inward projections, the inward extending projections being brought into engagement with the outward extending projection in response to the external reciprocal vibratory movement of the annular member, the vibratory engagement rotating the shaft member in a single direction.

A motor device comprising:
- a first member having a first plurality of equally pitched projections, said member being reciprocally vibratable;
- a second member having an axis, mounted adjacent the first member, the second member having a second plurality of equally pitched projections opposing and spaced from the first plurality of projections;
- at least the plurality of projections of one of the first and second members each having a surface that extends obliquely to corresponding opposing surfaces of the plurality of projections of the other of the first and second members;
- the first member, the second member and the projections being disposed and dimensioned for the oblique surfaces of the projections to engage the opposing projections to move the second member in one direction in response to the vibratory reciprocation of the first member.

The device of claim 8 wherein the second member rotates in one direction.
A motor device, comprising:
- an annular member movable linearly in a direction normal to an axis of the annular member in response to an applied external reciprocal vibratory pressure;
- a plurality of equally pitched inwardly extending bi-metallic projections positioned at an inner annulus edge of the annular member;
- the distal end of each of the projections being bent in one direction obliquely to the radii of the annular member;
- a rotatable shaft member having an axis and mounted coaxially within the annulus of the annular member;
- and
- a plurality of equally pitched outward projections extending in radial alignment with a radial line of the rotatable shaft member, the inward extending projections being brought into engagement with the outward extending projection in response to the external reciprocal vibratory movement of the annular member, the vibratory engagement rotating the shaft member in the one direction;
- and wherein the bimetal projections bend in the opposite oblique direction in accordance with a predetermined temperature for reversing rotation of the shaft member to turn in the opposite direction.

A motor device comprising:
- a first member having a first plurality of equally pitched projections, said member being reciprocally vibratable;
- a second member having an axis, mounted adjacent the first member, the second member having a second plurality of equally pitched projections opposing the first plurality of projections;
- at least the plurality of projections of one of the first and second members each being of bimetal and having a surface that extends obliquely to corresponding opposing surfaces of the plurality of projections of the other of the first and second members;
- the first member, the second member and the projections being disposed and dimensioned for the oblique surfaces of the bimetal projections to engage the opposing projections to move the second member in one direction in response to the vibratory reciprocation of the first member, wherein the bimetal projections bend in the opposite oblique direction in accordance with a predetermined temperature for reversing rotation of the shaft member to the opposite direction.
