PCT No. PCT/SE82/00122 Sec. 371 Date Dec. 13, 1982 Sec. 102(e) Date Dec. 13, 1982 PCT Filed Apr. 14, 1982 PCT Pub. No. WO82/03560 PCT Pub. Date Oct. 28, 1982.Roller skate comprising a plate (1) for the user's foot and one front wheel (2) and a rear wheel (3) having a convex curved running surface and rotably mounted on shafts (7, 5). One wheel is pivotable between side angle positions on either side of a center position in which the direction of rolling of the wheel concerned extends in the longitudinal direction of the skate. A steering mechanism (15) is provided for pivoting of the wheel (2) and having a sensing member (22) which is arranged to rest against the subsurface on which the wheel is designed to roll. The sensing member is connected with the pivotable wheel in such a way that the angle of pivoting is governed by the inclination of the skate in relation to the subsurface, due to the member resting against the subsurface. The steering arrangement is so designed that the rolling direction of the wheel extends in the longitudinal direction of the skate when this adopts a position at right angles to the subsurface with its standing longitudinal plane, while when the skate is inclined towards the subsurface during rolling it swivels in a different direction dependent on the direction of the inclination.
