ABSTRACT:
A land transportation device for compact, sandy and open land, with or without a slope, based on the intersection of two reinforced and identical truncated rings in orthogonal planes with respect to each other. The geometric centers shifted of the rings are shifted over the line of intersection of these planes. The weight of the device is reduced since it is made up of two light truncated rings, while at the same time, the cabin space is increased. The rings present a soft friction surface which gives the device better adherence to the ground, reducing the vibrations and facilitating the movement of the device. The device also possesses a hinge system which makes it possible to fold the ring on two axes, parallel to each other, thereby reducing its size. The disassembled device can be placed in a rectangular box for transportation and storage.
