Abstract
A skate is provided, consisting of an upper chassis (3) which supports a boot (4) and which is articulated onto a lower chassis (1) provided with rollers (2), about a pin (5) located in the front half of the lower chassis. The upper chassis (3) is elastically supported. The inclination of the upper chassis (3) can be modified using an adjustment device with prepositioning, comprising a wedging part and a prepositioning member (12) that arms a spring whose relaxation brings the wedging part into the desired position when it is released by the upper chassis. A relatively weak actuation spring is sufficient.
