PERFECTED LADDER FOR MOTOR VEHICLES AND ASSEMBLY METHOD THEREOF
A ladder (4) comprising: - a pair of uprights (8,12), directed along a prevailing vertical direction (Y-Y), - said uprights (8,12) being connected to each other by at least one cross member (16), perpendicular to said uprights (8,12), directed along a transverse direction (X-)X, perpendicular to said vertical direction (Y-Y), said cross member (16) acting as a step of the ladder (4), wherein - the uprights (8,12) comprise coupling portions (24) at the upper fixing ends (20,) - said coupling portions (24) having two horizontal planes (28,32) and a vertical joining rib (36), so as to present overall a 'C' shape, - said coupling portions (24) being provided with at least one fixing hole (40) for inserting at least one fixing bolt (44) of the ladder (4) to an associable chassis (48).
L'invention concerne une échelle (4) comprenant : une paire de montants (8, 12), dirigés le long d'une direction verticale dominante (Y-Y), lesdits montants (8, 12) étant reliés l'un à l'autre par au moins un élément transversal (16), perpendiculaire auxdits montants (8, 12), dirigé le long d'une direction transversale (X-X), perpendiculaire à ladite direction verticale (Y-Y), ledit élément transversal (16) agissant comme un échelon de l'échelle (4). Selon l'invention : les montants (8, 12) comprennent des portions d'accouplement (24) au niveau des extrémités de fixation supérieures (20), lesdites portions d'accouplement (24) ayant deux plans horizontaux (28, 32) et une nervure de jonction verticale (36), de manière à présenter globalement une forme en « C », lesdites portions d'accouplement (24) étant pourvues d'au moins un trou de fixation (40) servant à insérer au moins un boulon de fixation (44) de l'échelle (4) à un châssis associable (48).
