Abstract
The two skates steered by leaning sideways normally curve along circles of similar curvature. As the two circles are offset by the legs' distance they intersect. In order to avoid this disadvantage it is desirable that the outer leg's curved track has a larger radius than the inner leg's curved track. Using lean-controlled steered skates with tiltable wheels comprising a parallelogram fourfold linked chain including two horizontal cross-guides the purpose is achieved by affixing the two cross-guides rotatably to extensions of the frame in such a way that the rotation axis makes a solid angle with the vertical middle plane.
Claims1
a rolling device which is steered by leaning sideways, having at least one pair of wheels oriented side by side, wherein the two wheels of the wheel pair are rotatably affixed to two wheel holders and wherein the two wheel holders are pivotably interconnected using an upper horizontal cross-guide and a lower horizontal cross-guide so that a parallelogram or trapezium-like closed fourfold linked chain results, wherein the two horizontal cross-guides are rotatably affixed each to at least one extension of the frame of the rolling device, wherein the direction of the rotation axes makes a solid angle alpha with the direction of the pivot axes of the fourfold linked chain, wherein the two cross-guides and the at least one extension have bore-holes which accommodate axles, bearings, spherical bushings or the like allowing rotation around the said rotation axes, the said bore-holes being now positioned so that the said rotation axes each make a solid angle beta to the plane which is defined by being perpendicular to the wheels' axes and by being located in the middle of the distance between the two wheels of the wheel pair.
