Patent ID: 7948097

Claim:
An apparatus for actuating a locking element, comprising: a converter for converting mechanical into electrical energy, said converter comprising a Magnetic circuit ( 5 ) and an induction coil ( 1 ) through which magnetic flux from the magnetic circuit passes, wherein a first one of the magnetic circuit ( 5 ) and the induction coil ( 1 ) is formed as a movable component relative to the apparatus and a respective second one of the magnetic circuit ( 5 ) and the induction coil ( 1 ) is formed as a fixed component relative to the apparatus, the movable component is attached to the apparatus by a leaf spring ( 7 ), the movable component is arranged such that the movable component is deflectable so as to carry out oscillating movements in only one plane, the magnetic circuit ( 5 ) comprises two permanent magnets ( 2 , 3 ) arranged spaced apart in parallel to each other, the induction coil ( 1 ) is arranged in a space between the two magnets ( 2 , 3 ) maintaining gaps between the induction coil ( 1 ) and each of said magnets ( 2 , 3 ), and the movable component is arranged such that the movable component is deflectable so as to carry out oscillating movements in a direction transverse to a direction of the magnetic flux.
