Definitions

  • soles In the skiing world, particular attention is paid to the research and creation of equipment with soles able to produce the maximum speed on the snow. For this reason, in recent years, soles have been produced in sinterized Polyethylene with a variable density and mixed with particular additives like graphite powder, fluorine and other materials and mixtures which remain industrial secrets. The soles are therefore formed uniformly of a single material or mixture across their width, length and thickness. The soles produced in this way are then assembled as skis by the producer.
  • the faster ski is obviously the one that slides on the film of water.
  • This layer of water which acts as a lubricant between the sole and the snow is not uniform but instead has a thickness that gradually increases from the tip to the tail of the ski. Nevertheless, in conditions of high humidity and snow temperature, the excessive quantity of water that forms can cause the so called suction phenomenon, hence compromising the speed of the ski.
  • the object is hence to improve the sliding of the ski both when the veil of water is excessive or when the veil of water is not present
  • the scope of the present find is to favour the expulsion of excess water which forms between the sole and the snow by the insertion of wedges of water repellent material PTFE (Teflon), in the most critical points of the ski, similar or of another type as illustrated in Fig. (9)F.
  • PTFE water repellent material
  • These inserts can be placed along the entire length of the sole of the ski (from the tip to the tail of the ski). In particular in cross-country skis these inserts will be placed preferably in the rear area of the ski starting from the point where the heel of the boot is found towards the tail where the veil of water is greater and in the front part of the ski starting from the area which goes from the point where the tip of the foot is found towards the spatola of the ski.
  • inserts must be of such a shape that they will convey the excess water towards the sides of the ski expelling it to the outside.
  • the number of inserts, their form, their thickness, the type of material used and their placing are all to be considered as part of this present find as illustrated in Fig. N° (4) (5).
  • the ski moves on the snow deforming and/or shattering the "uneveness" present on the snow surface greatly reducing the sliding of the ski.
  • the scope of the present find is that of resolving the problem by inserting materials that create friction, for example rubber or other materials, in strategic points of the sole. The heat generated by these inserts during the sliding phase of the ski favour the formation of a film of water between the sole and the snow as illustrated in Fig. (1)C.
  • the number of these friction inserts must be such as to produce the right heating during the sliding phase so as to obtain an "energy exchange”: the creation of friction produces heat that in turn produces a veil of water that acts as a lubricant for the sole thereby increasing the sliding. This, in turn, increases the speed of the ski.
  • the friction inserts must be of a costituent material (polimeric plastics, elastomerics, rubber and others) and must be of a dimension, type of surface, outline, number and placement on the ski, to offer the most advantages possible in respect to the friction caused by the inserts themselves as illustrated in Fig. N° (1) (2) (3).
  • these inserts will be placed preferably in the front area of the ski starting from the balancing point of the ski itself towards the tip and from the zone between the heel of the boot and the tail of the ski.
  • These inserts can be of various materials, forms, widths and multiple thicknesses and even in flushtive shapes that are however designed to optimize the system, and are all considered inclusive of the present find.
  • a sole for skis obtained by multiple extrusion or coupling, by means of gluing or other systems, on the whole length, or part of it, with antirepellent plastic materials like PTFE (Teflon) or a mixture of elastomerics and other materials with a chemical composition that is different to the sole itself as shown in Fig. N° (6) (7).
  • antirepellent plastic materials like PTFE (Teflon) or a mixture of elastomerics and other materials with a chemical composition that is different to the sole itself as shown in Fig. N° (6) (7).
  • the inserts regarding both the systems for the formation of water particles (veil of water) or for the expulsion of excess water Fig. (9) C-F, can be placed on the inside of the sole as per example in Fig. D1, or they can occupy the entire length of the sole itself as in the example in Fig. D2. Furthermore, the inserts can be made of two or more different materials mounted between them with the scope of improving or augmenting the performance as in Fig. (8). Even in this case all the above mentioned premises are to be considered in regards to the form, the materials and the placement.
