Sports equipment for children's playground, has radial bearing with three coils, with third coil having cylindrical area forming gap with support, and an upper front surface along which the lower surface of the second coil slides

摘要

The second coil (2) has its inner cylindrical area (2a) slid against the inner cylindrical area of the first coil. A flange (7) overlaps the outer cylindrical area of the second coil. The third coil (3) has its cylindrical area (3a) forming an intermediate gap (9) with the support, and an upper front surface (3b) along which the lower surface (2d) of the second coil slides. A radial bearing (4) has three built-in coils (1-3), with the inner cylindrical area (1a) of the first coil (1) positioned at the external surface (5c) of a rotating support (5).
