摘要： A jack with a foot resting on the ground and with a supporting plate that rises away from the foot, lifts the vehicle, and pivots around one or more articulations on a supporting component around an axis paralleling the length of the vehicle. The object is to make it possible to compensate for tilting along the vehicle without causing unilateral stress that could damage the bottom of the vehicle with local pressure. The jack accordingly has at least one support (17) on or between the articulations (15 and 16) and between the supporting plate (8) and the supporting component (3), and the articulations allow a limited pitch paralleling the length of the vehicle on the part of the plate.

摘要： An automotive jack in which an upright member is provided with a pivotable base plate hinged on a first pivot at the bottom of the upright member. This upright member has a second pivot on which a supporting arm is turnable. The supporting arm is pivoted by an actuating device. A spring pivots the base plate along the length of the upright member, and the supporting arm has, at one end, a load interception head for pivoting the base plate through a stop against the force of the spring into a position at an angle to the length of the upright member when the jack is folded together. The sole of the base plate has an entire surface butting against the ground for any extensions and loads of the jack due to the pivoting of the base plate about the first pivot.
摘要翻译：一种汽车千斤顶，其中直立构件设置有铰接在直立构件的底部的第一枢轴上的可枢转的底板。该直立构件具有支撑臂可转动的第二枢轴。支撑臂由致动装置枢转。弹簧沿着直立构件的长度枢转基板，并且支撑臂的一端具有负载拦截头，该负载拦截头用于使基板抵抗弹簧的力而通过止动件枢转到与当千斤顶折叠在一起时直立构件的长度。由于基板围绕第一枢轴的枢转，基板的底部具有与顶板对接的任何伸展和负载的整个表面。

摘要： A jack in which a base plate is pivotable on an upright to a bottom surface. A supporting arm is also pivotable on the upright, and is actuated for being pivoted. The base plate is held in a predetermined position by a spring which has two sections. A first section of the spring rests against the upright and the base plate, whereas the second section of the spring rests against the base plate and an end of the supporting arm when this arm is completely folded up against the upright. The second section of the spring, furthermore, generates a spring torque which is directed opposite to the spring torque that is generated by the first spring section. The spring torque of the second spring section, moreover, exceeds the spring torque of the first spring section.
摘要翻译：一个千斤顶，其中底板可在直立件上枢转到底面。支撑臂也可在立柱上枢转，并被致动以枢转。基板通过具有两个部分的弹簧保持在预定位置。弹簧的第一部分靠在立柱和基板上，而弹簧的第二部分则抵靠着基板和支撑臂的一端，当这个臂完全折叠在立柱上时。此外，弹簧的第二部分产生与由第一弹簧部分产生的弹簧扭矩相反的弹簧扭矩。此外，第二弹簧部分的弹簧扭矩超过第一弹簧部分的弹簧扭矩。
