Steerable vehicle driven by physical strength of the user has four wheels, chassis, and steering basket in parallelogram-type assembly

摘要

The vehicle has up to four wheels or pairs of wheels. It has a chassis (2) allowing space for the user to move, and a steering basket (1). This is fastened to the chassis via joints (6), so that it can move freely to left or right dependent upon the desired steering direction, and forms a moveable parallelogram with the front pair of wheels (4) fastened to the side. The steering basket has pairs of steering supports (3), which carry the body weight and determine the direction of travel by moving to left and right. The chassis also has a stand board (21), to stiffen it, and to support one or both feet.
