Abstract:
PCT No. PCT/EP92/00860 Sec. 371 Date Oct. 15, 1993 Sec. 102(e) Date Oct. 15, 1993 PCT Filed Apr. 16, 1992 PCT Pub. No. WO93/16079 PCT Pub. Date Aug. 19, 1993.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). The axles are mounted on a chassis (52) of the device, and spaced apart in the longitudinal direction of the 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 the inner race means (25). The guide track has a center of curvature which defines a virtual axis (44) that forms the steering axis and is disposed on either the inside or the outside of the inner race means (25). The associated axle (40) cooperates with the arcuate guide track to permit pivotal steering movement of the wheel (10) by relative movement between the guide track and the axle.
