Definitions

  • the present invention relates to an improved ski construction.
  • skis In the utilization of skis it is desirable that the skis grip satisfactorily upon hard or soft vsnow and upon uphill or downhill terrain.
  • vIt is, therefore, among the objects of the present invention to provide a ski construction which may be readily adjusted or modified to accommodate different snow conditions or different terrain conditions permitting the inclusion in one ski of an all-around adaptability without necessitating substantially additional equipment and which adjustments may be readily made by the average skier without difficulty.
  • the central part of the ski be arched particularlywhen utilized for climbing uphill and to retain the shape it is necessary to lock the skis n together after usage with a block tied in between to cause the wood to retain the arch formation after each usage of the skis.
  • edge of the ski afford a certain and sure grip to the snow which cannot be attained Withan all Wooden construction and it has been found that solid -metal constructions are not altogether satisfactory for the edges of skis because of the weight and also of the fact that they weaken the wooden structure.
  • slots may be cut in the body thereof at predetermined intervals to enhance elasticity of the ski.
  • the side portions may be omitted with the result that the edges will run only along the bottom of the edges of the ski.
  • This groove is so shaped as to receive an intermediate edging device to enable better gripping of hard snow on which a central groove would not be of substan- 'tal Value.
