Abstract: An attachment member having a cross bar and a pair of legs is attached to the under side of a vehicle to be towed in such a manner that it is attached to the rear of the rear wheel axle and also in front of the rear wheel axle with the legs extending beneath the axle so as to be clear of the axle when the vehicle is resting on all four wheels. When it is desired to tow the vehicle a tow bar is fitted to the attachment means at two positions with the rear end of the tow bar protruding to the rear of the towed vehicle. The legs of the attachment member are provided with sliders which can be moved to positions beneath the axle so that when the rear end of the tow bar is raised, the sliders engage the under side of the rear wheel axle and the vehicle is lifted.

Abstract translation: 具有横杆和一对腿的附接构件被附接到车辆的下侧，以被牵引的方式使得其被附接到后轮轴的后部并且还附接到后轮轴的前方， 腿部延伸到轴下方，以便当车辆搁置在所有四个车轮上时，该车腿可以远离车轴。 当需要牵引车辆时，拖杆在两个位置处装配到附接装置，拖杆的后端突出到拖车的后部。 连接构件的腿部设置有可移动到轴下方的位置的滑块，使得当拖杆的后端升高时，滑块接合后轮轴的下侧并且车辆被提升。
