DAS SYSTEM SKIS FOR SIMULTANEOUS STEPLESS MOVEMENT Russian patent published in 2022 - IPC A63C5/06 A63C5/08 

FIELD: sports equipment.

SUBSTANCE: invention relates to ski movement and can be used for movement on a hard snow track. Skis for movement with simultaneous stepless movement, containing boots pivotally fixed on the shoe parts of the skis, while the soles are made in the form of cranks, on the free surface of the crank soles, connecting rods are pivotally, with one end are fixed, and the other ends pivotally interact with the sliders mounted on the shoe part of the ski bodies, made with the possibility of reversible linear movement, in the course of the user’s movement, while the front parts of the sliders interact with the dampers, while the efforts of the dampers on the sliders and the stroke of the sliders are regulated by screws, in addition, the screws with marks applied to them with digital information, made with the ability to be used as indicators, showing the compression force of the dampers and the angle of separation of the crank from the upper surface of the shoe part of the skis, and the distances between the points of the centers of the mentioned hinges form open triangles, made with the ability to change the stiffness of the system by changing the lengths of the adjustable sides of the open triangles, while the sliding surfaces on both sides of the shoe parts of the skis are made with the possibility of variable stiffness, allowing for a leg thrust to slide on parallel skis in the direction of movement, with simultaneous stepless moves, or when pushing with the legs in different directions at sharp angles in the direction of movement from the shoe parts of the skis, the user performs work in the form of a reversible elastic deformation of the skis, forming cyclic traces, in the form of second-order curves.

EFFECT: increase in the efficiency of the product is provided.
