Abstract

The elevator comprises a user accommodation platform (2), movable along a helical path over the steps (la), of the staircase. Inside a tubular guide (3) of circular cross-section is located is a truck formed by the two truck halves (4,5) which are provided respectively with the tabs (4a,5a) which connect to the platform (2) by passing through the helical slot (3a). The truck is associated with the guide (3) so that it can slide and rotate in contact with, and is provided with fluid actuated cylinder adapted to cause its translatory motion along the axis of the guide. An annular element (8) made of anti-friction material, is in contact with a disk (7), with a overlying disk (9) is provided with means for the resting of the lower truck half (4) which are constituted by the feet (9a,9b,9c,9d) which slide along s the helical guide (11) which follows the configuration of the spiral staircase (1). The actuation of the fluid-actuated cylinder with a stem (6) produces the translatory motion, which performs the intended helical motion induced by the contact of the slider (10) with the guide.
