A stairs lift system capable of converting stairs climbing operation into a walking movement along a horizontal plane. The system comprises an existing substrate flight of stairs (10) and a second, overlaying layer of stairs (16); each overlaying stair comprising a lifting element (16a). Mechanical, electronic or hydraulic means (134; 234; 334) are provided for lifting the top panel (16a) up to the height of the next-in-line overlaying stair. The lifting means are activated when sensing the presence of a subject having stepped on the first-in-line lifting element top panel (16a). The first-in-line lifting element returns to the initial position once the subject has stepped over to the next-in-line stair; and so forth.

L'invention concerne un système de levage pour escalier qui permet de convertir l'action de monter les escaliers en un mouvement de marche sur un plan horizontal. Ce système comprend une volée de marches d'escalier de support (10) et une seconde couche de marches (16) de recouvrement, chaque marche de recouvrement comprenant un élément de levage (16a). Des moyens mécaniques, électroniques ou hydrauliques (134; 234; 334) permettent de lever le panneau (16a) supérieur de la marche de recouvrement jusqu'à la hauteur de la marche de recouvrement suivante. Ces moyens de levage sont activés lorsque la présence d'une personne venue se placer sur le panneau supérieur du premier élément de levage de la succession est détectée. Le premier élément de levage de la succession retourne à la position initiale une fois que la personne s'est déplacée sur la marche suivante, et ainsi de suite.
