Roller skate with wheels in line - having ball bearing between hub and tyre and axis of hub being eccentric and cooperating with axle moving in curved hole against spring

摘要

The skate has its wheels (14) held between the lateral wings (11A) of the lower part of the chassis. Each wheel has a hub (17) which is fixed in rotation and has a ball bearing between it and the tyre (19). The transversal axle of articulation of the hub (13) is eccentric horizontally with respect to the centre of the wheel (O). A fixed axle (23), joined to the chassis, moves in a curved oblong hole (22) which is radial with respect to the eccentric axle. The axle rests on a spring (20) and its movement is limited by the ends (C, D) of the hole. USE/ADVANTAGE - Roller skate with wheels in line and each hub having eccentric axle changing its angular clearance and absorbing vibration.
