Abstract
A rolling device comprises a wheel pair, consisting of two wheels ( )affixed to wheel-holders ( ), which are interconnected by two cross-guides ( ) thus forming a parallelogram link chain. One cross-guide ( ) is rotatably secured to extension of the platform providing an acute angle between a rotation axis ( ) and the pivot axes ( ) of the four links which constitute the parallelogram link chain. The second cross-guide ( ) is secured at the platform extension using a universal joint. One such tilt-steering wheel pair mechanism together with at least one fixed wheel is attached at opposite ends of the rolling device to make it work.
