ABSTRACT A driving system which enables to move people or goods in a ver- tical, inclined, horizontal, circular pattern, or any other di- rection from a starting point "A" to a destination point "B", said driving system being based on the idea to transform rota- tional energy in translation movement by using two components: 1) a rotating drive sheave secured to a body carriage and equiped with an external helicoidal profile having a nominal medium diameter "Dm" and pitch "R", and 2) a guiding path extending between said points "A" and "B", comprising a plurality of equally spaced apart rollers, wherein the distance between two adjacent rollers is equal to said pitch "R"; sustaining means holding the said drive sheave in a constant adjacent relation to said guiding path, wherein the distance between the centre line of said drive sheave's helicoidal pro- file and the radial centre line axis of the adjacent engaged guiding path's roller is equal to "Dm"/2, enables that accord- ingly to the said drive sheave's direction of rotation, the said body carriage to be moved between said points "A" and "B" onward or backward. Or a driving system as described above where the two said components are: 1) a supporting body having wrapped around a helicoidal pattern a plurality of rollers, and 2) a guiding path comprising a plurality of helicoidal sectors; both said components being coaxially disposed and having the same nominal diameter "Dm" and pitch "R".
