Abstract:
A vehicle system, comprising a vehicle having two pairs of wheels and a bottom; and a device for transverse movement of said vehicle, said device comprising longitudinal rotatable axles, transverse rotatable axles, four rotatable wheels fixedly connected with said longitudinal rotatable axles, couplings through which said wheels are connected with said transverse rotatable axles, said transverse rotatable axles including at least two transverse rotatable axles which are spaced from one another in a longitudinal direction so that one of said pairs of wheels of said vehicle can contact one of said transverse rotatable axles and the other of said pairs of said wheels of said vehicle can contact the other of said transverse rotatable axles and thereby the rotation of said wheels of said vehicle causes a rotation of said wheels of said device; means for holding said device in a suspended condition under said bottom of said vehicle, said means including cables connecting said device with a handle for lowering and lifting of said device and also connectable with said axles of said vehicle, said cables having an opposite end connected to a semi-circular lever located in one of said couplings for blocking said device, said semi-circular lever having a radius corresponding to a radius of an axis of said device, said semi-circular lever having a convex surface provided with a projection having a side corresponding to openings on an axle of said device for contacting, so that when said cable is tightened, said semi-circular levers contact with the axle of said device to transfer a rotation of said wheels of said vehicle to a rotation of said wheels of said device and to block said rotation.
