International ClassA63C 017/02Foreign Application Priority Data1992-04-27 FRAbstractRoller skates in which the sole plate has a downward inclination or tilt towards the front in relation to the ground. The inclination of the roller skate is due to the fact that at the front a so-called "semi-rigid" steering system 7 is used, and at the rear a spring steering system 7' or another raised semi-rigid steering system is used, the combination of which provides an angle of inclination of between 3° and 15° in the unloaded position of the plate, thereby improving the comfort of the roller skate user. | |
