Abstract:
A lifting device for disabled people designed to be permanently installed at a location for overcoming a difference in level between a lower surface and an upper surface, comprising:a supporting frame mounted beneath said upper surface, a sliding foldaway platform movable between a retracted position and an extracted position with respect to said supporting frame and also movable in said extracted position between a lowered condition in which the platform rests on said lower surface and a raised condition in which the platform is substantially arranged at the level of said upper surface, articulated parallelogram linkage means connected between said platform and said frame and first electrically actuated means for moving said platform between said retracted position and said extracted position and second electrically actuated means for moving said platform by means of said articulated parallelogram linkage means between said lowered condition and said raised condition, wherein said platform is equipped with a rear extractable extension slidably mounted underneath the platform for movement between a retracted position and an extracted position in which the extension acts as a rear ramp for engaging said upper surface and wherein said sliding extension is provided with a rear board which can move between a closed position and an open position by effect of the movement of said sliding extension between said retracted position and said extracted position respectively.
