发明名称 Dynamic play equipment for children
摘要 The invention concerns a dynamic game for children consisting of a cylinder (1) open at its ends and capable of rotating about its longitudinal central axis (X). The invention is characterized in that: the cylindrical body (1) consists of parallel slats (6); the slats (6) are maintained in place by two peripheral rings (8) fixed on their outer surface and supporting a continuous raceway (10); the diameter of the cylinder (1) is such that the user should be lying down; the pairs of support rollers (4) are positioned such that they form between them an angle of at least 120° relative to the cylinder center; the support frame (2) for the cylinder (1) consists of two fixed rings (12) supporting the guide rollers (4) pressed against the two raceways (10) provided at the cylinder periphery.
