FIELD: snow moving vehicles. SUBSTANCE: proposed folding sledge contains framework on which strips are rigidly secured to form seat, and supports to which strips are rigidly secured to form backrest. Framework with support is mounted on runners with footstep. Support is made for moving forward relative to runners by means of articulated clamps installed in point of butt-joining of support with runners. Strips forming backrest for sledging in sitting position are rigidly secured being driven into space between strips of seat in rear part of sledge to hold backrest in said position. The same strips in position for sledging in lying position are rigidly secured in space between strips of seat in front part of sledge to be held in seal position. Backrest forming strips are rigidly connected to support by means of U-shaped plate and cross plate, and vertical parts of U-shaped plate are commensurable in height with height between framework and runners. EFFECT: simplified design, improved reliability, possibility of transformation of sledge for sledging in sitting position or lying position. 2 dwg |
