Definitions

  • the invention has for its object a ski of universal utility which does not have the above mentioned drawbacks.
  • the ski according to the invention is characterized by the fact that the outer covering of the sole of the ski is divided into different parts having different frictional characteristics relative to the snow. To obtain these results there will be selected different materials which differ as to the physical condition of the surface, such as by their coefficient of friction, by the hardness of the material, by their resistance to abrasion and generally by all characteristics which determine sliding of skis.
  • the covering of the sole is longitudinally divided into two equal parts each one of which has a very different characteristic from that of the other material relative to its ability to slide. It is evident that it is possible to provide a different geometric division and a greater number of 3,520,546 Patented July 14, 1970 materials according to need. It can be advantageous to paint these different materials in different colours.
  • FIGS. 1 and 2 show schematically two soles of skis, each provided with a covering according to the invention positioned according to two modifications.
  • FIG. 1 shows a sole subdivided longitudinally into two equal parts one of which is covered by material 10 and the other by material 11.
  • the length of the sole is subdivided into four segments of substantially equal lengths covered alternately with material 10 and material 11.
  • the covering parts are applied to the sole of the ski in a conventional manner well known to those skilled in the art and which does not form part of the present invention.
  • a ski for use under various surface conditions of snow comprising an elongate ski body having a continu ous smooth running surface, said running surface being divided by the longitudinal center line of the ski into two adjacent equal areas each extending from said center line to the respective lateral edge of the ski body, each of said areas having different frictional surface characteristics from the other.
  • a ski for use under various snow conditions comprising an elongate ski body having a continuous smooth running surface, said running surface being divided by transverse lines into a plurality of substantially equal adjacent areas arranged successively in the lengthwise direction of the ski, adjacent ones of said areas having different frictional surface characteristics.
