Roller ski having leg operated braking means

摘要

Roller footwear devices, such as roller skis and roller skates, having sets of wheels on spaced apart parallel axles mounted on a web supporting foot-fastening means as well as brake means arranged to act on at least one of the wheels. A brake-actuating means is operatively associated with the brake means via intermediate actuation means so arranged as to cause the brake-actuating means to activate the brake means by action from the leg or knee region on moving the latter substantially at right angles to the axles of the wheels starting from a position adopted by this region during normal operation of the device.
