SELF-ROTATING LEVER TEETERING-BOARD Russian patent published in 2015 - IPC A63G11/00 

FIELD: machine building.

SUBSTANCE: invention relates to devices for carnival for children and adults, for muscle exercises and development of vestibular apparatus. The teetering-board can be used both room for young children, and large for adults and popular for pleasure grounds.
