摘要

A jack to lift cars with a stationary leg of U-shaped cross section, and equipped with a foot of settlement; with a support arm disposed in the stationary leg rotatably about a transverse axis of rotation disposed in the branches of its u-profile and applicable against the bottoms of a vehicle to be lifted, and with a threaded spindle operable by means of a crank, which on one side is supported on the upper end of the stationary leg on a spindle nut and, on the other hand, by a corresponding support, on the support arm, in such a way that it can be made rotate, fitting the spindle nut, with two diametrically opposed pivots arranged in it, in support slots, open on one side, of the u profile branches of the stationary leg, and meeting the open end of the slots on the side of the joining web of the stationary column which joins the u-profile branches together, while the grooves extend into said branches in an inclined direction relative to the longitudinal direction thereof. So as to form an enlarged support opening in a circular shape in the interior and the pivots being of circular cylindrical cross section, correspondingly adapted by means of at least one flattening, arranged at the periphery, to the width of the part of the grooves support formed narrowly on the side of the opening, for the purpose of introducing the pivots in the support grooves, characterized in that the support grooves (32) extend in the branches (14) of the u profile of the standing leg ( 10), from above and outside, inclined inwards and downwards, and because the flattening (44) of the pivots (40) is provided in the part of the periphery of the pivots that is set apart from the support (30) of the spindle.
