    摘要： A small, personal, all terrain vehicle is disclosed of the articulated, multi-unit type. A first and second unit, having track members pivotably mounted thereto, are also pivotably and rotatably interconnected to each other. A motor is provided in the second unit for driving the track members of the first and second units. The first unit includes a seat for a driver and a steering mechanism causing the pivoting of the second unit with respect to the first unit. The all terrain vehicle is of a small size, in the preferred embodiment being four feet wide and eight feet long, for the personal transportation of the driver. The all terrain vehicle provides advantageous weight distribution in that the weight of the driver of the all terrain vehicle is located in the first unit to provide substantial traction to the track members of the first unit and the weight of the motor is located in the second unit to provide substantial traction to the track members of the second unit. The interconnection of the first and second units and the pivotable interconnection of the track members to the first and second units assure that all four track members engage the travel surface.

    摘要： Collapsible frame for wheeled vehicles, comprising a main structure to which rear forks are pivoted and carry wheels, a front footboard carrying a steering wheel, and a seat. Said forks, footboard and seat are clampable to an open position where the frame is at running conditions and are operable to assume a closed position where the forks and footboard enter the main structure on which the seat can be overturned, in this case the frame occupying a rather reduced volume or space.

    摘要： The present invention provides a multi-stage tilting and multi-rotor flying car including: a main frame externally shaped like a rectangle and internally partitioned to have a grid structure; a body mounted at a center of the main frame in consideration of balance; a plurality of rotors mounted to the main frame to face upward; a plurality of wheels mounted to the main frame to face downward; body wings provided at opposite sides of the body; and an automatic driving controller provided in the body and controlling the rotors and the wheels, thereby having effects on spending only the minimum necessary flying time for taking off and landing in a narrow area, and improving flight performance three times higher in flight time and flight speed and five times higher in fight distance than a rotary-wing aircraft such as a helicopter while flying in the fixed-wing mode.

    摘要： Disclosed is an air-transportable and highly autonomous vehicle of the type comprising a single-unit chassis supported in the front by a set of driving and steering wheels and at the rear by two axles to which suspension leaf-springs are coupled. The leaf-springs may slide longitudinally relative to the axles. The stack of leaves is carried in its transverse median plane by an equalizer mechanism which is angularly movable on the end of a pivotal shaft. In this vehicle, each end of a pivotal arm (17) is carried in a fixed sleeve (18) with which it is rendered rigid, the sleeve being extended downwardly by a member (20) for fixing one of the ends (21.sub.1) of a part (21)of the reaction links. This sleeve is surmounted by an equalizer support (22) which is also fixed and receives the ends (23.sub.1) of the other part (23) of the links, the free ends (21.sub.2 -23.sub.2) of all of the links (21-23) being assembled with supports which are fixed against rotation and clamped to the two axles (16). The suspension leaf-springs (15) are fixed to a base (31) which is mounted to be angularly movable on rolling bearings (32) carried by the two ends of the pivotal shaft (16).
