摘要

A disc or wheel (3) has balls (4) filled with air, gas or foam rubber and functioning as a cog. The balls are fixed in the disc or wheel with axle (4) or shaft through a hole (6). A counter wheel (7) has cavities (8) and is pivot mounted, and lifts a column (9) for fixing a transparent or partly covered dome (10). Figures such as animals, people or objects can depict movements of daily life to the child by passing beneath the dome and are set in motion by a drive wheel (3). USE/ADVANTAGE - The child's toy has no harmful parts as the rotary connection consists of balls in matching recesses on counter wheel.
