Yo-yo has free-running casing positioned at least partly within external boundary of rotation wheel and mounted to rotate freely wrt. wheel, device(s) for fixing casing wrt. wheel

摘要

The yo-yo has a rotation wheel (1) and a chord (5) to be held by the user, whereby the wheel has a spooling device (6) for the chord and an essentially linear acceleration force that acts on the yo-yo is at least partly converted into a rotation of the wheel. The yo-yo also has a free-running casing (10) positioned at least partly within the external boundary of the rotation wheel and mounted to rotate freely wrt. the wheel and at least one device (20) for fixing the casing wrt. the wheel.
