Patent ID: 8901759

Claim:
System ( 1 ) for converting potential or kinetic energy of a body weighing upon or travelling over a support or transit plane into useful energy comprising: a fixed framework ( 2 ) with which at least one footboard ( 3 ) is associated in a mobile manner defining said support or transit plane and that is mobile, by the action of said body, between an initial position and an end position, characterised in that it comprises: a magnetic interaction device ( 4 ) comprising at least a fixed element ( 42 ) and a mobile element ( 43 ) that are associated with one another in a mobile manner relative to one another, said mobile element ( 43 ) of which is associated with at least one magnet ( 40 ); means for counteracting the relative motion of said fixed element ( 42 ) and said mobile element ( 43 ) and at least one activation magnet ( 41 ), associated with said at least one footboard ( 3 ) or with said fixed framework ( 2 ), for setting said mobile element ( 43 ) in motion with respect to said fixed element ( 42 ), wherein said magnetic interaction device takes up a first configuration in which said activation magnet ( 41 ) is outside of the field of interaction with the said at least one magnet ( 40 ) of said mobile element ( 43 ) and a second configuration in which said activation magnet ( 41 ) is inside the field of interaction with said at least one magnet ( 40 ) of said mobile element ( 43 ); and means for transmitting the motion of said footboard ( 3 ) between said initial position and said end position to one from said activation magnet ( 41 ) and the combination of said fixed element ( 42 ) and said mobile element ( 43 ) for the passage of said magnetic interaction device ( 4 ) from said first configuration to said second configuration, vice-versa, setting said mobile element ( 43 ) in motion with respect to the fixed element ( 42 ) without any contact, wherein the relative motion of said fixed element ( 42 ) and said mobile element ( 43 ) makes useful energy available that can be used in the form of variation of a magnetic flux.
