Definitions

  • the invention relates to a ski or a snowboard with layers of transparent plastic. Skis with Layers of transparent plastic are e.g. through the FR-A 2 512 681 has become known.
  • a ski is increasingly winning that too Appearance of the ski influences the purchase decision.
  • various means including technical ones, that are used for Influencing the appearance of the ski can be used. So e.g. are already transparent layers as top layers for the top of the ski or as a tread surface for Protection of the decor or of decorative layers used either on the back of the transparent layer or are attached below the transparent outer layer.
  • the object of the invention is to use transparent To expand ski components, on the one hand to Influencing the appearance of the ski and / or on the other to achieve a technical effect.
  • the ski or the snowboard at least partially perpendicular to the Tread level transparent over its entire cross-sectional height
  • the ski or that Snowboard in its entirety perpendicular to the tread plane transparent over its entire cross-sectional height whereby however, this may not be the case in all areas of the ski must (therefore "at least in some areas ").
  • functional parts made of opaque material, especially metal, such as for alpine skis the steel edges, binding attachment parts or reinforcing elements form zones which are formed by that exclude transparency. It is also possible, for decorative reasons or for marking opaque, i.e. attaching non-transparent inserts in the ski body, which then contrast zones to the transparent ones Form areas of the ski.
  • Transparent in the sense of the invention means not only clear, but also translucent.
  • those parts of the ski are to be referred to as “transparent” where the degree of transmission in the visible spectral range is different from zero, for example at least 10%, but is preferably considerably higher.
  • a source of light that is located, for example, under the running surface of the ski should at least still be perceived as a glow on the ski surface.
  • the transparency can also be "colored", so it does not have to extend across the full width of the visible spectrum. On the other hand, discoloration due to radiation (light, UV) or aging is rather undesirable. Transparent materials that are as stable as possible with respect to radiation and aging should therefore be used with regard to their transparency.
  • the inner components at least be transparent in some areas, e.g. the bearing Layers made of glass fiber reinforced plastic can exist in the transparent glass fibers with transparent resin are bound. If the reinforcement inserts partly made of transparent glass fibers and partly consist of opaque carbon fibers also special technical and design Effects are achieved.
  • the core zones of the ski can be seen either by using transparent core material or make it transparent that inner Cavities are formed. For this, e.g. the supporting one Ski body formed from one or more hollow bodies whose walls (at least partially) are made of transparent glass fiber reinforced plastic.
  • honeycomb cell walls are not made of transparent Material.
  • honeycomb cell walls also made of glass fiber reinforced, if necessary - Made of plastic.
  • the invention not only enables the production of Skis of previously unknown appearance, but also gives an insight into the inside of the ski to Determine processing errors, e.g. a incorrect orientation of the glass fibers or air bubbles in hardened synthetic resin.
  • Fiber composite plastics with directional reinforcement fibers can their excellent material properties such as high strength, rigidity and corrosion resistance only fully play when it is succeeds in increasing the fibers according to the load orientate. Even small deviations from the direction of the fibers to the direction of loading cause considerable losses in the strength of the component.
  • the control the correct orientation of the reinforcing fibers so far either failed during ski making for technological reasons or because the individual ski components were not allowed to be viewed (were opaque). Then you have consciously Fiber composite materials oversized to one to compensate for possible loss of strength, however at the expense of the total weight.
  • the invention can be applied to all types of Skis (alpine skis, cross-country skis, water skis etc.) apply, with the term ski also Snowboards are included.
  • Fig. 1 shows in cross section a ski that one at appropriate choice of materials in the sense of the invention as can train transparent skis.
  • the ski according to FIG. 1 belongs to the type of shell skis and consists of a flat lower assembly with the outsole 1, e.g. made of polyethylene, and the side steel edges 2.
  • the inside of the ski is laterally and upwards from a shell 3 made of unreinforced Plastic enclosed.
  • the inner bearing Construction of the ski is done with a hollow body 4 Walls 5,6 made of fiber-reinforced thermoplastic or thermosetting plastic.
  • the inner hollow body 4 fills the interior between the top shell 3 and the lower assembly 1.2 such that the Outer walls 5 on the inner walls of the shell 3 or lower assembly 1.2.
  • the hollow body 4 has also vertical partition walls 6, which the Interior of the hollow body 4 in three air-filled hollow chambers divide.
  • a transparent for the outsole 1 Polyethylene and also for the shell 3 a transparent Plastic, e.g. a UV stabilized thermoplastic, such as such as thermoplastic polyurethane or polyamide used.
  • a transparent synthetic resins e.g. Polyester resin or Epoxy resin used as a binder for the fiber inlays the fiber deposits entirely or predominantly consist of transparent glass fibers.
  • Such a ski could then be viewed from above 2 appearance, with the ski body in the areas A is transparent from top to bottom, while the edge zones B, furthermore the tip and end area C, D and the binding attachment area E appears opaque because of the Steel edges 2, also the tip and end protection made of metal and a reinforcement insert or binding attachment plate in the binding attachment area.
  • the Tip protection could e.g. also from a so-called Clip-on tip exist, this clip-on tip also can be at least partially transparent, in particular from transparent, preferably thermoplastic Plastic can exist.
  • FIG. 4 Additional dark vertical stripes characterize the appearance the transparent ski (Fig. 4), if like Fig. 3 can be seen, e.g. on the top of the inner Hollow body 4 longitudinal inserts 7 e.g. out Resin-bonded carbon fibers are arranged.
  • This Deposits 7 have a triangular shape in the case of FIG. 3 Cross section on and are over an intermediate wall 6 arranged.
  • FIGS. 5 and 6 also has in the embodiment the appearance of the transparent ski dark opaque stripes F, but now with flat strip-shaped inserts 8 between the top of the inner hollow body 4 and the shell 3 are formed.
  • FIGS. 5 and 6 in the rest of a glass fiber braid existing fiber reinforcements of the two lateral hollow chambers individual threads 9 made of carbon fibers braided, e.g. in an inclined position (helical), which then as a dark zigzag pattern or Cross pattern G appear.
  • the compressed air becomes overpressure removed in the hoses and the ski removed from the mold. After demolding, any will still be over the side surfaces of the lower component group protrude Cut off edges of the cover film.
  • the hoses from the cavities of the now cured hollow body for reuse be removed. If the tubes in the ski body must remain with regard to the effect according to the invention at least partially transparent be, e.g. are made of transparent polyamide.
