The present invention relates to a Locking/unlocking system of superimposable elements, comprising a first element (2) or upper element, and a second element (3), or lower element, to be locked and unlocked, superimposed each other along a plane (4) of relative motion, and a operating device (1), said system being characterized in that said first element (2) and said second element (3) provide each one the same number of a plurality of housings (210, 310), and reciprocally positioned so as to form pairs of housings (210, 310), each one providing inside centring means (220, 320), said system being further characterized in that it provides a plurality of first magnetic elements (230') having a first length, a plurality of second magnetic elements (230") having a second length, lower than the length of said plurality of first magnetic elements (230'), and a plurality of third magnetic elements (230'"), having a third length equal to the half of the sum of said first and second lengths, the total height of said pairs of housings (210, 310) having the measure equal to or bigger than the double of said first length, inside each one of said pairs of housings (210, 310) being provided a pair of magnets, consisting of one of said first (230') magnetic elements and of one of said second (230") magnetic elements, or a pair of said third (230"') magnetic elements, the position each other and the orientation of their polarity being combined randomly, so that their faced ends correspond to, or are offset with respect to, said plane (4), said operating device (1) providing a plurality of interference elements (110, 120, 130), comprised of magnetic (120, 130) material, ferromagnetic material or magnetically inert (110) material, oriented and combined so as to attract, reject or leave unaltered said pairs of magnets (230', 230"; 230'") so as, bringing said operating device (1) close to one of said two elements (2; 3), said pairs of magnets (230', 230"; 230'") are all aligned along said plane (4), permitting the relative motion of the two elements (2, 3). |
