CONSTRUCTION SET FOR DEVELOPMENT OF RUNNING GEAR DRIVE OF LARGE MODELS Russian patent published in 2024 - IPC A63H33/04 A63H31/08 

FIELD: sports; games; mass entertainment.

SUBSTANCE: solution relates to large model constructors intended for development of spatial thinking in children and gaining experience in creation of functional structures and models. Constructor developing drive of running gear of large models contains one or more wheels, which is a disc with gear or two discs, between which there is a gear. At that, pinion diameter is smaller than that of disc(s). Besides, this set comprises transmission gears secured on model body to make one gearing per wheel gear or several independent gearing.
