Abstract: A roller skate in which the automatic action of normal walking produces a driving action on the wheels by means of a pedal on which the foot is placed. A heel kick to the pedal of the skate on the driving surface puts a multi-position control device into operative position for driving action. During the lifting of the skate, the control device comes back to a standby position. A toe kick to the pedal effects a braking position of the control device. The braking then is controlled by the depression of the pedal and is progressive. The control device is locked in the position selected and a new position requires the reversion to the standby position by lifting of the skate.

Abstract: Propelling roller skate comprising a selector on which the pedal is articulated and which is adapted to be placed in two positions: a propulsion position and a braking position. The selector is articulated on the brake device which also carries the shaft of the propulsion lever.The brake device is itself adapted to turn about the drive shaft of the driving wheels. The selector carries a stop finger carrying a brake stop and a propulsion stop cooperating respectively with the brake device and with the propulsion device to prevent the movement which does not correspond to the position selected.

Abstract: A roller skate in which the automatic action of normal walking produces a driving action on the wheels. A heel kick to the pedal of the skate causes the putting in operative position of a control device. During the lifting of the skate, the control device comes back to a standby position. A toe kick to the pedal after the waiting position causes the putting in braking position of the control device. The braking is controlled by the depression of the pedal and is progressive. The control device is locked in the position selected and a new position requires the reversion to the standby position.
