Abstract
Vertical stairs include a bearing structure 2, which is arranged between a first station “A” and at least one second station “B”, and at least one board 3, which can slide by at least one slide 31 along at least one guide 41 in a mechanical system 4, adapted to move the at least one board 3 along the guide 41. The mechanical system 4 allows the at least one board 3 to be moved along a vertical axis “Z” as a function of the distribution of the weight of at least one user “U” on at least one portion of the at least one board 3, and as a function of the direction in which the user “U” wants to move along the vertical axis “Z” between the stations.
