A mobility aid system for overcoming a level difference as a flight of stairs that extends between a landing (A) and a floor (Z) that is raised with respect to the landing by a vertical drop (H) assessed on a vertical axis (Y), the flight of stairs comprising a plurality of steps (S) each defining a treading surface (C) arranged horizontally and spaced vertically with respect to the preceding one by a drop (h), the system comprising a plurality of lifting devices each comprising a frame, a lifting platform being attached to the frame pivotally with respect to a horizontal direction (X) perpendicular to the vertical axis (Y), said platform being movable between a resting position arranged in a substantially vertical arrangement according to said axis (Y) to a working position arranged in substantially horizontal arrangement according to the direction (X), in said working position said platform also being movable along said frame according to said vertical axis (Y), said system comprising a lifting device arranged on the landing (A) of the flight of stairs and one lifting device for each step (S);
- the aid system further comprises an elevator base that can be translated along said vertical axis (Y) between the landing (A) and the raised floor (Z), wherein the elevator base is defined by one or more of the lifting platforms actuated in combination in translation along the respective frames.
A group of two or more lifting devices each of which comprising a frame, a platform being attached to the frame pivotally with respect to a horizontal direction (X) perpendicular to the vertical axis (Y), said platform being movable between a resting position arranged in a substantially vertical arrangement according to said axis (Y) to a working position arranged in substantially horizontal arrangement according to the direction (X), in said working position said platform also being movable along said frame according to said vertical axis (Y), said lifting device further comprising driving means to move the platform vertically and platform overturning means to bring the platform from the resting position to the working position, said group comprising means for managing said driving and overturning means of said two or more lifting devices to move said platforms of said two or more lifting devices in a coordinate manner in order to arrange said platforms at different levels with respect to said vertical axis (Y) to define a flight of stairs,
- wherein each frame defines at least a lower face perpendicular to said vertical axis (Y) and two main faces of which a front face and the other rear face, that are mutually opposite and parallel and arranged along the axis (Y), the attachment between said platform and said frame being performed on such lower face or on the rear face, wherein said platform in said resting position is leant against said front face.
