Abstract

Scissor jack vehicle lift, being of the type that are constituted by four arms of section in "U" articulated at their ends, determining a deformable parallelogram, presenting the ends of the arms corresponding to two opposite vertex teeth that they mesh with each other, while between the other two remaining vertices there is a spindle which is operable by one of its ends, by threading the end corresponding to the opposite vertex in a nut-like part and which also serves as means of articulation of the ends of the concurrent arms in such vertex; essentially, it is characterized in that said nut-shaped part is constituted by a cylindrical body provided with a through-hole radially affected by a thread on which the spindle is threaded, said hole being slightly displaced towards one of the ends of the cylindrical body itself, for which the end extends into an axial appendage of smaller diameter, determining an annular staggering between it and the base or end of the cylindrical body from which it emerges; with the particularity that the main cylindrical body is through through orifices faced and practiced for this purpose in two of the lateral and superimposed wings of the "U" profiles constituting the arms, while the emerging axial appendage passes through of holes provided in the same manner in the other two wings of the said "U" profiles of the arms, the staging determining the end of the cylindrical body itself and the emerging axial appendix, against the internal wing, while externally said appendix is riveted against the lateral surface of the external wing superimposed on the previous one and corresponding to the "U" profile of one of the articulated arms.
