Roller or inline skate for e.g. recreation, has spring ratchet cooperating with asymmetric toothed ratchet wheel fixed on wheel of skate, so that rotation of ratchet wheel is free in positive direction of movement

摘要

The skate has a spring ratchet (2) cooperating with an asymmetric toothed ratchet wheel (4) fixed on a wheel (3) of a skate, so that the rotation of the wheel (4) is free in a positive direction of movement and is blocked in a negative direction of movement. The spring ratchet is rigidly fixed on a frame (1) and is slightly supported on the asymmetric wheel. The positive direction is the direction of forward motion of a human being.
