2108484 9218210 PCTABS00016 A sporting device steerable by weight displacement, for example in the form of a roller skate or roller ski comprises at least first and second wheels (10A, 10B) mounted on bearings for rotation about respective axles (46), said axles being mounted on said device, for example on a chassis (52) of said device, and spaced apart in the longitudinal direction of said device, with at least one of the wheels being steerable on displacement of the user's weight about an inclined steering axis (44) which intersects the ground substantially at the center (64A, 64B) of the contact patch of the respective wheel with the ground. The inclined steerable axis (44) extends downwardly and rearwardly for a front wheel (10A) and downwardly and forwardly for a rear wheel (10B). The steering axis is defined by a generally arcuate guide track (40; 42; 38; 87) provided within said inner race means (25). Said guide track has a center of curvature defining a virtual axis (44) forming said steering axis and disposed either inside or outside of said inner race means (25). The associated axle (40) has means (72, 74; 45, 47; 86) cooperating with said arcuate guide track to permit pivotal steering movement of said wheel (10) by relative movement between said guide track and said axle.
