O DISPOSITIVO CONSISTE NUMA ESTRUTURA DE ALAVANCA QUE SE ACOPLA A UMA CADEIRA DE RODAS ATRAVÉS DO EIXO TRASEIRO (5) E DO SISTEMA DE FIXAÇÃO (2). ESTE DISPOSITIVO COMPREENDE DOIS EIXOS PARALELOS, EIXO FRONTAL (3) E EIXO TRASEIRO (5), LIGADOS ENTRE SI POR UM EIXO PERPENDICULAR (4). AO EIXO TRASEIRO (5) ESTÃO ACOPLADAS AS RODAS DIANTEIRAS (6) E RODAS TRASEIRAS (11), E AO EIXO FRONTAL (3) ESTÃO LIGADOS OS GUIADORES (1) E UMA ESTRUTURA DE TRAVÃO (9), QUE INCLUI UMA MANETE (10). A RODA GRANDE DE PASSAGEM DE ESFORÇO (7) E RODA PEQUENA DE PASSAGEM DE ESFORÇO (8) PERMITEM TRANSFERIR O ESFORÇO DE MOVIMENTO DA RODA GRANDE DA CADEIRA DE RODAS PARA AS RODAS TRASEIRAS (11) DO DISPOSITIVO.THE PRESENT INVENTION REFERS TO A DEVICE THAT ALLOWS THE USER OF A WHEELCHAIR TO TRANSPOSE UNLEVELS, SUCH AS FOR EXAMPLE: A STEP, WITH INDEPENDENCE. THE DEVICE CONSISTS OF A LEVER STRUCTURE THAT ENGAGES A WHEELCHAIR VIA THE REAR AXLE (5) AND THE FIXING SYSTEM (2). THIS DEVICE COMPRISES TWO PARALLEL AXLES, FRONT AXLE (3) AND REAR AXLE (5), CONNECTED TO EACH OTHER BY A PERPENDICULAR AXLE (4). TO THE REAR AXLE (5) THE FRONT WHEELS (6) AND REAR WHEELS (11) ARE COUPLED, AND TO THE FRONT AXLE (3) THE HANDLEBARS (1) AND A BRAKE STRUCTURE (9) ARE CONNECTED, WHICH INCLUDES A LEVER (10 ).
