Definitions
- the invention relates to a ski with layers of transparent plastic.
- the appearance of the ski also has an increasing influence on the decision to buy.
- various means including technical ones, that are used to influence the appearance of the ski. So e.g. transparent layers are already used as cover layers for the top of the ski or as tread coverings to protect the decor or decorative layers, which are applied either on the back of the transparent layer or below the transparent outer layer.
- the object of the invention is to expand the use of transparent ski components, on the one hand to influence the appearance of the ski and / or on the other hand to achieve a technical effect.
- the entire ski body is transparent at least in some areas. It is therefore not just a surface layer or tread layer that is transparent in order to be able to recognize lettering, symbols or decorations lying behind or behind it, but according to the invention the ski as such, ie in its entirety - at least in some areas - is transparent.
- the ski is transparent over its entire cross-sectional height at least perpendicular to the tread plane, although this does not have to be the case at all points on the ski (hence "at least For example, functional parts made of opaque material, especially metal, such as the steel edges, binding attachment parts or reinforcing elements form in alpine skis, zones which are excluded from transparency. It is also possible for decorative reasons or for marking opaque, ie to insert non-transparent inserts in the ski body, which then form contrast zones with the transparent 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 transmittance in the visible spectral range is different from zero, for example at least 10%, but is preferably considerably higher.
- a light source located, for example, under the tread of the ski should at least 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 must also be transparent at least in some areas, for example the load-bearing ones Layers that can consist of glass fiber reinforced plastic in which transparent glass fibers are bound with transparent synthetic resin. If the reinforcing inserts consist partly of transparent glass fibers and partly of opaque carbon fibers, special technical and design effects can also be achieved.
- the core zones of the ski can be made transparent either by using transparent core material or by forming internal cavities.
- the supporting ski body can be formed from one or more hollow bodies, the walls of which (at least partially) consist of transparent glass fiber-reinforced plastic. Another possibility would be the arrangement of a honeycomb core with standing honeycomb cell walls, which then also one
- honeycomb cell walls themselves are not made of transparent material.
- the honeycomb cell walls can also be made of plastic, if necessary reinforced with glass fibers.
- the invention not only enables the production of skis of previously unknown appearance, but also provides an insight into the interior of the ski in order to determine any processing errors, for example incorrect orientation of the glass fibers or air bubbles in the hardened synthetic resin.
- Fiber composite plastics with directional reinforcement fibers can only fully exploit their excellent material properties such as high strength, rigidity and corrosion resistance if the fibers can be oriented according to the load. 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 of the correct orientation of the reinforcement fibers during the ski production has so far failed either for technological reasons or also because the individual ski components did not allow a look through (were opaque).
- the fiber composite materials were then deliberately overdimensioned to compensate for a possible loss of strength, but at the expense of the total weight.
- skis alpine skis, cross-country skis, water skis etc.
- ski also encompassing other devices, such as snowboards.
- FIGS. 2, 4 and 6 show ski cross-sections of different exemplary embodiments and FIGS. 2, 4 and 6 the associated views of the ski in a top view.
- Fig. 1 shows in cross section a ski that can be designed as a transparent ski with the appropriate choice of material in the sense of the invention.
- 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 enclosed on the side and upwards by a shell 3 made of non-reinforced plastic.
- Construction of the ski is formed by a hollow body 4 with walls 5, 6 made of fiber-reinforced thermoplastic or thermosetting plastic.
- the inner hollow body 4 fills the interior between the upper shell 3 and the lower assembly 1, 2 such that the
- Outer walls 5 rest against the inner walls of the shell 3 or the lower assembly 1, 2.
- the hollow body 4 also has vertical partition walls 6 which divide the interior of the hollow body 4 into three air-filled hollow chambers.
- a transparent polyethylene is used for the outsole 1 and also a transparent plastic for the shell 3, e.g. a UV-stabilized thermoplastic, such as thermoplastic polyurethane or polyamide, is used.
- a transparent plastic for the shell 3 e.g. a UV-stabilized thermoplastic, such as thermoplastic polyurethane or polyamide.
- transparent synthetic resins e.g. Polyester resin or epoxy resin is used as a binder for the fiber inlays, the fiber inlays consisting entirely or predominantly of transparent glass fibers.
- Such a ski could then have an appearance according to FIG. 2 in a top view, the ski body being transparent in the areas A from top to bottom, while the edge zones B, also the tip and end area C, D and the binding attachment area E appear 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 also consist, for example, of a so-called clip-on tip, whereby this clip-on tip can also be at least partially transparent, in particular made of transparent, preferably thermoplastic, plastic.
- Additional dark longitudinal stripes characterize the appearance of the transparent ski (FIG. 4) if, as can be seen from FIG. 3, e.g. on the top of the inner hollow body 4 longitudinal inserts 7 e.g. made of resin-bonded carbon fibers. In the case of FIG. 3, these inserts 7 have a triangular cross section and are arranged over an intermediate wall 6.
- the appearance of the transparent ski has dark opaque stripes F, which are now formed by flat strip-shaped inserts 8 between the top of the inner hollow body 4 and the shell 3.
- individual threads 9 made of carbon fibers are also braided in the fiber reinforcements of the two lateral hollow chambers, which are otherwise made of a glass fiber tubular braid, for example in an inclined position (helical), which then form a dark zigzag pattern or cross pattern G appear.
- a ski in accordance with the illustrated exemplary embodiments can be carried out using a mold consisting of two mold halves, in the mold cavity of which the ski is shaped, the following process steps being provided: a) into the recess of the first (lower) mold half Components of the lower assembly (outsole.
- the compressed air pressure in the hoses is eliminated and the ski is removed from the mold. After demolding, any will still be over the edges of the cover film projecting beyond the side surfaces of the lower component group are cut off.
- the hoses can be removed from the cavities of the now hardened hollow bodies for reuse. If the hoses remain in the ski body, they must be at least partially transparent with regard to the effect according to the invention, for example consist of transparent polyamide.
