<p>A ski sledge is disclosed which comprises steering means, a front ski, two guide rods and two rear skis. The front ski is pivoted on the steering means, while both guide rods are connected at their front ends in common with the steering means and at their rear ends to a rear ski coordinated therewith. The connection between rear skis and guide rods is accomplished by first pivot means comprising annular spring means, which are deformable radially and peripherally, but substantially rigid in directions transverse to the annulus plane. Second pivot means comprising similar annular spring means serve for connection between guide rods and the steering means However, the latter spring means 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.</p> |
