DEVICE FOR PRODUCING THE ENERGY REQUIRED FOR OPERATING A SMALL ELECTRICAL APPLIANCE

摘要

The invention concerns an apparatus (1) comprising at least an element (3), such as a key, for controlling a function, a multiplying-gear including a motion input wheel (12) and a motion output wheel (13), and means for storing and restoring electric power. The invention is characterised in that: said motion input wheel (12) comprises means (28, 29, 35, 36, 41, 45) to be urged in engagement with each said element (3) when said element (3) starts its displacement such that said displacement drives in rotation said input wheel (12), those same means (28, 29, 35, 36, 41, 45) enabling said input wheel to be disengaged from each said element (3), at the end of said element (3) displacement, such that said end of displacement does not stop the wheel (12) rotation; said motion output wheel (13) comprises a permanent magnet which, over its periphery, forms an alternation of North and South magnetic poles; the device comprises at least a coil (42) placed in the proximity of the motion output wheel (13).
