  • the device described can adapt perfectly and indifferently to any length and type of ski: piste, background, hike ... and allows the creation of a monoski, a snowboard , or even a sled depending on the circumstances and the temporary wishes of the user.
  • FIG. 4 illustrates a variant of the previous embodiment in which the sole 4 extends beyond the end of the heels of the skis, forms a half-loop around a rigid return member 2 in which, for example, the heels of the skis, and ends with a tension strap 17 provided with a member 9 for securing and adjusting tension of the usual type coming to cooperate with the second rigid member 3 already mentioned and shaped for this function, and fixed to the skis 5 of any appropriate way (to the fastening 7, to the possible brake, or other body).
  • recesses for the heels of the skis of the return member 2 may advantageously have a shape with a decreasing section towards the rear to receive any width of skis.
  • FIG. 5 another embodiment of the invention is illustrated.
  • the sole 4 is made up, apart from the anterior 1 and posterior 3 rigid members, of a succession of rigid elements or plates 18, articulated to each other in the longitudinal direction and playing both the role of the spacers 8 of the previous case with their support members 11 on the upper surface of the skis and, in the deployed state, forming by their lower face the sliding surface of the sole 4.
  • the articulation between these successive elements 18 can be done, as illustrated in FIG. 6, by the elasticity of a very flexible sliding skin 41, glued on elements 18, and allowing their easy folding. From place to place, a larger gap 45 can be left between two successive elements 18 to allow accordion folding, a removable element of appropriate shape and advantageously provided with support members 11 on the upper face of the skis, coming after deployment ensure the mechanical continuity of the sole.
  • FIG. 7 another type of articulation of the rigid elements 18 is schematically represented. This articulation is done by conventional hinges 46, placed alternately in the upper part and in the lower part of the elements 18 to allow easy accordion folding. These elements 18 already have on the underside the necessary qualities of sliding on snow. Otherwise, an adhesive sliding skin can always be added before use, as is usual with the usual seal skins.
  • the elements 18 can also be, as shown in FIG. 8, discrete detached elements coming to nest successively in each other by complementary shapes 47, 48, the problem of the sliding surface being solved in an identical manner to the previous case.
  • FIG. 9 an exploded cross-section is shown, an embodiment of one of the elements 18 corresponding to FIGS. 5 to 8.
  • the element comprises a rigid core 40 corresponding to the thickness of the skis 5 and to their spacing, and carrying support members 11 on the skis 5.
