BALANCED POSITIONAL GAME DEVICE Russian patent published in 2022 - IPC A63F3/00 

FIELD: balanced positional games.

SUBSTANCE: invention relates to balanced positional games, where weighted game pieces (for example, chess, checkers) are used as game elements. The device consists of a game table (GT) with a playing field (PF) for game pieces (GP) with an area of ​​ GT, a larger area of ​​ PF, a base having a lower part in contact with the PF, and a horizontal upper part; a support assembly installed between the upper part of the base and the lower surface of the GT, having an upper support with a recess fixed to the lower part of the GT, a support element (SE) interacting with the recess in the upper support, ensuring the mobility of the GT relative to the upper part (UP) of the SE; GT weights attached to the underside of the GT, providing the position of the center of gravity GT below the contact surface of the HF OE with a recess in the upper support, while the recess in the upper support has the shape of a trihedral prism with roundings of the upper part, and the SE has the shape of a prism with roundings in the upper part with radii smaller than the radii of roundings in the upper part of the upper supports; the angle α between the side surfaces of the SE HF and the recess in the upper support is determined by the formula: where ƒ_sl is the coefficient of sliding friction GP over PF.

EFFECT: increased sensitivity to the weight of the GP and the occurrence of imbalance and elimination of the possibility of free rotation of the GT about the vertical axis in the event of an imbalance when removing or installing the GP in the plane of the table.
