Abstract
The roller skate is fitted with a brake comprising at least one pair of disks (16, 17) supporting, through their tapered side, the two sides of at least the rear wheel (6) when the skater displaces his or her weight backwards. Braking is effected through the friction of the disks on the wheel, i.e. through the friction of the flat side of the disks on a brake lining. In one system of operation, the disks are fitted on a support fixed to the boot and joined to a frame bearing the wheels. In another system of operation, the disks are fitted on a main frame bearing the boot and the front wheels, the two rear wheels being fitted on an auxiliary frame joined to the main frame.
