FIELD: transport engineering.
SUBSTANCE: invention to sledge with handlebar. Proposed device contains ski in which support 2 with seat 3 is mounted. Runners 6 are found on bottom of ski and recess is made for turnable skate 5. When moving down the slope in deep snow, device slides on bottom of ski, while when moving along ice-covered surface or hard crust, it slides on runners 6. skate 5 is arranged in front part of ski and is secured on steering column 12, and keel 8 is secured on axle 7 in rear part of ski, skate and keel being controlled by handlebar 14 but turn in opposite sides relative to direction of movement of device. Skate 5 sets direction of movement. When turning handlebar, for instance, to the left, skate, rigidly coupled with handlebar, also turns to the left, pulling front part of ski to the left, and keel 8, turning to the right, will bring rear part of ski to the right, thus accelerating entering left-hand turn. Skate 5 and keel 8 project over sliding surface of ski by 5-10 mm.
EFFECT: facilitated steerability and increased maneuverability.
