Abstract
Abstract There is provided a steering mechanism for a wind propelled land vehicle wherein steering is made possible by the footboard being connected with the front axle by means of a steering head in the manner of a hinge connection inclined at an angle to the direction of travel. This connection features two bushes spaced a distance apart from each other, between which is positioned a sleeve affixed to the footboard. A steering pivot pin, whose longitudinal axis inclines at an angle to the direction of travel, is fitted through the bushes and the sleeve. This connection of the footboard with the front axle enables steering by a transfer of the weight of a person standing on the footboard causing the latter to be tilted out of its horizontal position into an inclined position. This action generates a torque which is transmitted to the front axle, causing this to deflect, so that the direction of travel is changed.
