ABSTRACT:
A ski-sledge is disclosed which comprises steering column, a front ski, two guide rods and two rear skis. The front ski is pivoted on the steering column, while both guide rods are connected at their front ends in common with the steering column and at their rear ends to a rear ski coordinated therewith. The connection between rear skis and guide rods is accomplished by first pivot joints comprising annular spring assembly, which are deformable radially and peripherally, but substantially rigid in directions transverse to the annulus plane. Second pivot joints comprising similar annular spring assemblies serve for connection between guide rods and the steering column. However, the latter spring assemblies are nearly rigid in radial direction. Due to these features the ski-sledge is easier and more precisely to ride and generally better to handle.
