ABSTRACT:
The variable geometry wheeled conveyance includes front and rear pairs of wheels carried by a frame longitudinally spaced from one another for rotation about longitudinally spaced axes in a first configuration of the conveyance. A parallelogram linkage connects the wheels and the frame. By displacing the linkage, the wheels are movable into a second configuration with each wheel being rotatable about a transverse axis longitudinally spaced from every other wheel. A timer initiates transformation from the first to the second configuration and also causes a change in a gear ratio from the drive motor to the wheels to simultaneously upon such transformation change the speed of the conveyance.
