ABSTRACT:
A minicar which can be folded into a smaller size, when not in use, is provided. The minicar is comprised of two main frames which are connected by a parallelogram linkage system. The minicar is unfolded and folded by swinging one of the frames in an arc with respect to the other frame. A separate linkage system is attached to the parallelogram linkage system to fold and unfold the rear wheels of the minicar. The rear wheels swing in an arc when the minicar is being folded or unfolded. The minicar has two stable states, the folded state and the unfolded state. In the unfolded state, one frame member is above and offset from the other frame member and the wheels are in the operating position. When the minicar is in the folded state, one frame is almost directly above the other frame and all the wheels are almost completely under the top frame. The minicar also comprises a foldable enclosure which folds into layers when the minicar is not being used.
