SKI - OR TREKKING- STICK EQUIPPED WITH MAGNETIC- INDUCTIVE HARVESTER DEVICE FOR ELECTRIC GENERATION

摘要

A ski- or trekking-pole (1) is described, composed of at least one shaft (3) interposed between at least one handle (5) and at least one ring (7) placed at the two opposite ends of the shaft (3), comprising at least one harvester device (9) for generating electric current composed of at least one moving magnetic element (11) sliding along at least one sliding guide (13); at least one fixed magnetic element (15) arranged in the vertically lower end of the sliding guide (13), the fixed magnetic element (15) and the moving magnetic element (11) sliding along the sliding guide (13) being mutually oriented in such a way as to oppose the two faces with the same polarity in order to generate a magnetic repulsion force; and at least one first winding (17) made of electrically conductive material adapted to concatenate a magnetic field of the moving magnetic element (11) sliding along the sliding guide (13).
