Abstract:
A ring assembly for encircling a finger, said ring assembly comprising, in combination, a radially inner ring and a radially outer ring, each of said rings having a diameter, the diameter of the radially outer ring, being larger than the diameter of the radially inner ring, said rings being concentric and being located in the same plane, each of said rings defining an outermost circumferential surface, said rings each being adapted to encircle a finger, said circumferential surfaces of said rings facing each other radially and being separated from each other by at least a radial working clearance space so as to be coaxially rotatable relative to each other, a plurality of magnets mounted fixedly in said radially outer ring and a plurality of magnets mounted fixedly in said radially inner ring, said magnets being disposed respectively adjacent the radial working clearance space separating said radially inner ring from said radially outer ring, said plurality of magnets being also spaced circumferentially apart, one of said inner ring and said outer ring having at least one portion extending radially beyond a portion of said other ring, whereby said inner and outer rings are kept in approximate axial alignment with each other.
