Definitions

  • the innovation concerns an all-plastic ski, especially cross-country skis, with a lower G F K laminate (laminate made of glass fiber reinforced plastic) bearing a tread surface on the underside, an upper GRP laminate forming the top surface and a filling arranged between the upper and lower GRP laminate made of foamed plastic.
  • a lower G F K laminate laminate made of glass fiber reinforced plastic bearing a tread surface on the underside
  • an upper GRP laminate forming the top surface
  • All-plastic cross-country skis of the type mentioned above are characterized by a relatively simple construction, but have the disadvantage that the tension of the ski required in the so-called impression zone of the ski (wax zone or no-wax zone of the ski) is difficult to achieve and can only be set relatively imprecisely.
  • a relatively large cross-section must be selected or the upper or lower GRP laminate reinforced, which undesirably increases the material expenditure and the weight of the ski.
  • the innovation is therefore based on the task of avoiding these disadvantages to design a full-plastic ski, especially cross-country skis, of the type mentioned in such a way that the medium tension of the ski (ie the tension of the ski in the impression zone) is reduced while reducing the amount of material and weight and simple manufacture wide limits and can be set very precisely.
  • This object is renewal according achieved in that at the two outer sides of the ski in the region of its A ballonszone each one arranged between the upper and the lower GRP laminate, the side profile of the ski in the area of the impression zone appropriately shaped web is provided from tissue laminate.
  • the production of the ski according to the invention can be carried out in a simple manner so that the two fabric laminate webs are fixed on the two side cheeks of the mold by means of adhesive before the mold is foamed.
  • At least the end of the two fabric laminate webs pointing towards the ski tip is tapered in height and thickness and has a slender, tapering design.
  • the two fabric laminate webs do not hinder the foaming of the interior, which is usually carried out from the ski tip.
  • the thickness of the fabric laminate webs can be between 0.4 and 1 mm.
  • the fabric laminate webs are made transparent, it is possible to print them on the inside, the print being protected against damage by the fabric laminate.
  • the fabric laminate webs provided according to the innovation provide a very desirable lateral protection of the ski against damage of all kinds, especially in the impression zone of the ski (containing the binding area).
  • the cross-country ski 1 contains a lower GRP laminate 3 carrying a tread surface 2 on its underside, an upper GRP laminate 4 forming the top surface, a filling 5 made of foamed plastic, in particular polyurethane, arranged between the upper and lower GRP laminate, and two Fabric laminate webs 6 and 7.
  • These fabric laminate webs 6 and 7 are arranged on the two outer sides of the ski in the region of its impression zone and are shaped corresponding to the side profile of the ski in the region of the impression zone (cf. FIG. 1).
  • the two ends of the fabric laminate webs 6 and 7 are tapered in height and thickness and have a slender, tapering design.
  • This ski is manufactured using a foaming process, with the entry being made at the tip of the ski.
  • the fabric laminate webs are fixed to the metallic side walls of the ski shape by means of adhesive before foaming.
