Abrégé

Stair climber (1) comprising a supporting frame (2), a maneuvering tiller (3) constrained to said frame, and a tracked movement device (4) combined with said frame to displace said stair climber along a staircase (S), or along a sliding plane (P), said stair climber further comprising lifting means (5) to lift said tracked device (4) from said sliding plane (P), said lifting means comprising at least one first rear wheel (6) and at least one supporting lever (7) having a first arm (8) to which said at least one first rear wheel is rotatably constrained around a first horizontal axis (X), said supporting lever (7) being rotatably constrained to said supporting frame around a second horizontal axis (Y), wherein said supporting lever (7) comprises a second arm (9) distinct from said at least one first arm (8) and rotatable around said at least one second horizontal axis (Y), and wherein said lifting means further comprise at least one second rear wheel (10) constrained to said at least one second arm (9) in a position with respect to said at least one first rear wheel such that said at least one second rear wheel (10) and said at least one first rear wheel (6) are contemporaneously in contact with said sliding plane (P) at least when said maneuvering tiller (3) is subject to a thrust torque to rotate said supporting frame (2) backwards around said second horizontal axis (Y) and to lift said tracked device (4) from said sliding plane (P), characterized in that said at least one second rear wheel (10) is swivellingly constrained to said at least one second arm (9).

Abrégé

Stairlift (1) for fixed staircase and/or escalator, comprising a supporting frame (2), having a main body (2a) extended vertically and a platform (2b) adapted to carry, in cooperation with said main body, the weight of the load to be lifted on said fixed staircase and/or escalator, and a tracked movement device (3) constrained and movable on command with respect to said frame between an operative position (OP1), wherein it moves said stairlift along a fixed staircase or along a sliding plane, and a non-operative position (OP2), wherein it remains raised from said fixed staircase or said sliding plane, said frame further comprising at least one rotating back wheel (4) that rotates around a first horizontal axis (X) and is constrained integrally to said frame, said back wheel (4) being arranged, with respect to said tracked device, so that to contact said sliding plane or a first stair of an escalator, at least when said tracked movement device (3) is in its non-operative position (OP2), and to be raised from the sliding plane or from said first stair of said escalator, at least when said tracked movement device is in its operative position (OP1), said stairlift being characterized by comprising at least one front supporting leg (5) constrained and movable on command with respect to said frame (2) between a first position (PI), in which in cooperation with said back wheel (4), it is in contact with said sliding plane or a further stair of said escalator, and a second position (P2), in which it is raised from said escalator or said sliding plane.
